Description
- The present invention relates to the field of bulk transfer machines for particulate materials, and more particularly to a nozzle for providing particulate materials to a suction intake hose connected to a bulk transfer apparatus.
- Pneumatic bulk transfer apparatuses are widely used in agriculture and industry for transferring grain and various other types of particulate materials such as, for example, grain, fertilizer, pellets, etc. Such devices have substantially facilitated the bulk transfer of particulate materials, a previously laborious and time-consuming task accomplished by shoveling. For example, bulk transfer apparatuses are used for transferring grain from a storage facility of a farm to a delivery truck. Typically, an end portion of an intake hose is placed by an operator in close proximity to the particulate materials that are to be transferred, which are rendered airborne by an airstream caused by suction through the intake hose.
- To facilitate portability and enable use at different locations, pneumatic bulk transfer apparatuses have been provided as mobile units, for example, mounted on a trailer and powered by a tractor.
- Unfortunately, in various applications there is a need for using a long intake hose making it difficult for an operator to handle the end portion of the intake hose, in particular in a confined storage facility. Furthermore, using a long intake hose substantially increases suction loss, thus, the airstream for rendering the particulate materials airborne is reduced causing a substantial reduction in the efficiency of the transfer of the particulate materials. This is of particular concern when mobile units having limited power are employed.
- It is desirable to provide a nozzle for being connected to the end portion of the intake hose of a bulk transfer apparatus that is simple and easily maneuverable.
- It is also desirable to provide a nozzle for being connected to the end portion of the intake hose of a bulk transfer apparatus that has an improved rate of transfer of particulate materials when suction is weak.
- It is also desirable to provide a nozzle that is adapted for providing an active area for receiving particulate material that is significantly wider than the width of the vacuum hose.
- Accordingly, one object of the present invention is to provide a nozzle for being connected to the end portion of the intake hose of a bulk transfer apparatus that is simple and easily maneuverable.
- Another object of the present invention is to provide a nozzle for being connected to the end portion of the intake hose of a bulk transfer apparatus that has an improved rate of transfer of particulate materials when suction is weak.
- Another object of the present invention is to provide a nozzle that is adapted for providing an active area for receiving particulate material that is significantly wider than the width of the vacuum hose.
- According to one aspect of the present invention, there is provided a nozzle for providing particulate materials to a suction intake hose connected to a bulk transfer apparatus. A body structure of the nozzle comprises a connecting mechanism for connecting to an end portion of the suction intake hose. A support mechanism is mechanically connected to the body structure for movably supporting the nozzle. A particulate materials transport mechanism is placed in front of the body structure. The particulate materials transport mechanism comprises a movable mechanical structure for mechanically transporting the particulate materials into an airstream generated by suction through the suction intake hose. A hood is mounted to a front portion of the body structure for guiding the airstream towards an opening in fluid communication with the connecting mechanism.
- According to another aspect of the present invention, there is further provided a nozzle for providing particulate materials to a suction intake hose connected to a bulk transfer apparatus. A body structure of the nozzle comprises a connecting mechanism for connecting to an end portion of the suction intake hose. Two independently rotatable wheels are mounted to a left hand side of the body structure and a right hand side of the body structure in proximity to a rear portion of the body structure. A first drive mechanism and a second drive mechanism drive the first wheel and the second wheel, respectively. The first drive mechanism and the second drive mechanism are capable of simultaneously driving the first wheel in a forward direction and the second wheel in a rearward direction. A particulate materials transport mechanism is placed in front of the body structure. The particulate materials transport mechanism comprises a movable mechanical structure for mechanically transporting the particulate materials into an airstream generated by suction through the suction intake hose. A hood is mounted to a front portion of the body structure for guiding the airstream towards an opening in fluid communication with the connecting mechanism.
- The advantage of the present invention is that it provides a nozzle for being connected to the end portion of the intake hose of a bulk transfer apparatus that is simple and easily maneuverable.
- A further advantage of the present invention is that it provides a nozzle for being connected to the end portion of the intake hose of a bulk transfer apparatus that has an improved rate of transfer of particulate materials when suction is weak.

- Referring to
FIGS. 1 a to 1 c, anozzle 100 for providing particulate materials to a suction intake hose connected to a bulk transfer apparatus according to a preferred embodiment of the invention is provided. Abody structure 7 of thenozzle 100 comprises aconnecting mechanism 3 for connecting to an end portion of the suction intake hose (not shown) of the bulk transfer apparatus. The intake hose is connected using, for example, mating connectors, a screw mechanism, a clamp mechanism, or a tight fit between the intake hose and a tube portion of theconnecting mechanism 3. A support mechanism such as, for example,wheel spindle assembly 4 is mechanically connected to thebody structure 7 for movably supporting the nozzle. Ahood 1 is mounted to a front portion of thebody structure 7. Thehood 1 comprises anopening 3A which is connected via a duct to theconnecting mechanism 3 which is placed at a rear portion of thebody structure 7. A particulatematerials transport mechanism 2 is placed in front of thebody structure 7 and is covered at least partially by thehood 1. The particulatematerials transport mechanism 2 is movable mounted to the hood 1 (as shown inFIG. 1 a) or, alternatively, mounted to the front portion of thebody structure 7 using a suitable holding mechanism such as, for example, a cantilever structure. The particulatematerials transport mechanism 2 comprises a movable mechanical structure such as, for example, an auger, for mechanically transporting the particulate materials into an airstream generated by suction through the suction intake hose. For example, the particulatematerials transport mechanism 2 transports the particulate materials to an area in immediate proximity to the opening 3A. Thehood 1 guides the airstream with the airborne particulate materials towards theopening 3A in thehood 1. The particulatematerials transport mechanism 2 is rotatably mounted to thehood 1 using mounts known in the art such as, for example, various types of bearings. The particulatematerials transport mechanism 2 is driven using a drive mechanism such as, for example,electric motor 15A andbelt drive 15B comprising a belt and pulleys mounted to theelectric motor 15A and the particulatematerials transport mechanism 2 outside thehood 1. - The
body structure 7, theconnecting mechanism 3, thehood 1, and the auger are preferably made of a metal such as, for example, steel or aluminum. Of course other materials such as, for example, plastic materials or carbon fiber materials are also employable. - As illustrated in
FIG. 1 a, the particulatematerials transport mechanism 2 preferably comprises an auger rotatable mounted to thehood 1 and oriented substantially horizontal with a left hand portion and a right hand portion each transporting the particulate materials towards the center, i.e. in front of the opening 3A. Employment of the particulatematerials transport mechanism 2 increases the amount of particulate materials rendered airborne into the airstream and, therefore, improves the rate of transfer of the particulate material, in particular when suction is weak. The problem of weak suction is frequently encountered in agriculture when a long intake hose is needed or the hose becomes fully or partially clogged or filled. - Preferably, the support mechanism comprises two independently rotatable
wheel spindle assemblies 4 with a firstwheel spindle assembly 4 being mounted to a left hand side of thebody structure 7 and a secondwheel spindle assembly 4 being mounted to a right hand side of thebody structure 7. Thewheel spindle assemblies 4 are rotatably mounted to thebody structure 7 using mounts known in the art such as, for example, various types of bearings. Further preferably, thewheel spindle assemblies 4 are mounted to a rear portion of thebody structure 7. In the preferred embodiment, illustrated inFIGS. 1 a and 1 b, a first drive mechanism and a second drive mechanism are employed for driving the first wheel and the second wheel, respectively. The first drive mechanism and the second drive mechanism are capable of driving the first wheel and the second wheel differently. For example, the first drive mechanism and the second drive mechanism are capable of simultaneously driving the first wheel in either a forward or rearward direction and the second wheel in either a forward or rearward direction. The first drive mechanism and the second drive mechanism comprise, for example, preferably variable speed electric motors 8 and 9 in concert withbelt drives - Alternatively, pneumatic or hydraulic motors are employed. Further alternatively, chain drives, shaft drives or direct drives are used instead of the belt drives 6 and 10. In a further alternative embodiment of the present invention, an arrangement of one or more belts may be provided mounted on various diameter pulleys to provide the wheels with operator variable speed in a manner known to a person skilled in the art.
- The capability of simultaneously driving one wheel forward and the other rearward substantially increases the maneuverability of the
nozzle 100 by enabling turning of thenozzle 100 around a substantially vertically oriented axis placed between the twowheels 4. Increased maneuverability is advantageous when thenozzle 100 is used in confined spaces which are frequently encountered in storage facilities. - In the preferred embodiment the
nozzle 100 comprises ahandle 5 mounted to thebody structure 7 in proximity to aplane 19 through the center of thefirst wheel 4 and the center of thesecond wheel 4 and oriented substantially vertical, as illustrated in Figure 1 c. This placement of thehandle 5 substantially simplifies handling of the nozzle by an operator by slightly pushing down thehandle 5 for lifting thehood 1 off the ground and driving thenozzle using controls 11 disposed onswitch mount 12. For example, a left hand control is used for controlling the left hand drive and a right hand control is used for controlling the right hand drive. Further controls are optionally placed on the switch mount such as, for example, a control for controlling the particulatematerials transport mechanism 2 and a control for remotely controlling the bulk transfer apparatus. - Handling of the
nozzle 100 is further simplified by placing the connectingmechanism 3 in proximity to theplane 19 between thefirst wheel 4 and thesecond wheel 4, in order to minimize movement of the intake hose during turning of the nozzle. - Optionally, the first drive mechanism and the second drive mechanism are omitted and the support mechanism comprises only the two independently
rotatable wheels 4. The nozzle is then manually moved by an operator using thehandle 5. - Further optionally, the
nozzle 100 comprises a lefthand side caster 20 and a righthand side caster 20 mounted, for example, to thehood 1, as illustrated inFIGS. 2 a and 2 b, or, alternatively, to the front portion of thebody structure 7. - In alternative embodiments, the movable mechanical structure of the particulate
materials transport mechanism 2 comprises, for example, one or more rotatably mounted cylinders having rods or bristles, made of, for example, metal or plastic material, protruding there from, as illustrated inFIGS. 3 a and 3 b. In a further alternative embodiment of the present invention, drag chain conveyors (not shown) are connected to the front of the nozzle to draw particulate material into the airstream of the nozzle. - The
nozzle 100 is, for example, electrically operated with the power being provided, for example, via an electric power cable attached to the intake hose. - Optionally, the
nozzle 100 comprises headlights 14 mounted, for example, to a top front portion of thehood 1, as illustrated inFIG. 1 a, facilitating use of the nozzle in sparse lighting conditions. - Further optionally, the
nozzle 100 comprises a sensor orcamera 13 mounted, for example, to thehandle 5. The sensor orcamera 13 are useful, for example, for remotely sensing the intake of the particulate materials and/or for sensing a dust concentration in the air surrounding the nozzle, thus, increasing safety by, for example, warning an operator when there is an explosive dust concentration in the air. - In a
further embodiment 200 the nozzle is remotely operable by providing aremote control mechanism 30 for remotely controlling the first and the second drive mechanism. For example, a remotely located operator is provided with video images from thecamera 13 displayed on a monitor (not shown) and moves thenozzle 200 by using, for example, a joystick providing control commands to the nozzle viacable 32. Optionally, the particulatematerials transport mechanism 2 is also remotely controlled usingremote control mechanism 30. Alternatively, wireless transmission is employed. - In one embodiment of the present invention, in place of wheels, preferably rubberized tracks (not shown) are provided to support and guide the nozzle.
- The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
