Apparatus for discharging flowable material from a vehicle
FIELD OF THE INVENTION
This invention relates to an apparatus for discharging flowable material from a vehicle, and in particular to an apparatus for discharging different materials from a container mounted on a vehicle, and to a vehicle incorporating such apparatus.
BACKGROUND OF THE INVENTION
Flowable bulk material, such as animal feed, wood pellets or wood chips, is typically transported in a container mounted on vehicles or on a trailer towed by a towing vehicle, such container being fitted with a discharge apparatus for discharging material therefrom. The simplest type of discharge apparatus is a closable gate at the rear end of the container, the container being adapted to be tipped such that material falls out of the opened gate under gravity. This method of discharging material is hard to control in terms of low rate and amount of material delivered, is labour intensive and slow.
A more effective discharge apparatus comprises a pneumatic system, wherein flowable material is blown through a delivery conduit coupled at one end to a source of pressurise air (e.g. a vehicle mounted blower) and at an opposite end of a flexible delivery pipe whereby the material can be delivered to a desired location, such a storage bin, the material being passed from the container into the delivery conduit via a rotary valve, said rotary valve serving as an airlock between the delivery conduit and the container and as a means for metering the flow of material into the delivery conduit.
Such rotary valves typically comprise a cylindrical housing having an upper inlet and a lower outlet and having a multi-vane rotor rotatably mounted within the housing in close sliding contact in the inner surfaces of the housing. Rotation of the rotor causes the vanes to transfer material from the inlet to the outlet while minimising the flow of air from the delivery conduit back into the container.
Such rotary valves have to overcome any adverse characteristics of the product being handled. Therefore the design of the rotary valve, in particular the design of the vanes of the rotor thereof, will vary depending on the material to be handled thereby. For rotary valves intended to handle animal feed the vanes are typically formed from metal and are arranged in close sliding contact with the inner surfaces of the housing. However, such close fitting relatively rigid vanes are not suitable for other materials, in particular for wood chips, due to the risk of small particles of the material jamming between the vanes and the housing. For such applications rotary valves having vanes fitted with flexible elastomeric tips that can deflect to avoid such jamming problems are used while still retaining a suitably air tight seal against the inner walls of the valve housing. Therefore such vehicles tend to be designed for use with a specific type of material and different vehicles may be required to deal with different materials. To handle a range of materials a range of vehicles may be required, which can be costly and uneconomic for the haulier.

DETAILED DESCRIPTION OF THE DRAWINGS
A vehicle incorporating a discharge apparatus in accordance with an embodiment of the present invention is illustrated in the accompanying drawings. The vehicle comprises a trailer 2 to be towed behind a convention tractor unit upon which is mounted a substantially rectangular container 4 of conventional construction. It is envisaged that the container may be directly mounted on the chassis a vehicle rather than on a trailer as shown. The vehicle/trailer may include a conventional hydraulic tipping system so that the container 4 can be brought into a tipping position for the purpose of emptying. A discharge opening 6 having a closable gate is provided in a rear wall 8 of the container through which material may be discharged under gravity when the container 4 is brought into its tipping position.
A main discharge apparatus 10 used for emptying flowable material from the container 4, for example animal feed, is integrally fitted to the rear end of the container, as best shown in Figure 2. The main discharge apparatus 10 is mounted beneath a rear end of the container 4 and comprises a rotary valve 12 mounted below an outlet 14 in the floor of the container 4 adjacent the rear wall 8 of the container 4 and a transversely extending discharge 16 conduit mounted below the rotary valve 12. One end of the discharge conduit is coupled to a blower (not shown) mounted on and driven by the vehicle and an opposite end of the discharge conduit incorporates a coupling permitting a further delivery hose (not shown) to be coupled thereto, whereby, in use, the main discharge apparatus can discharge material, delivered into the delivery conduit 16 from the rotary valve 12, through the delivery conduit 16 and the further delivery hose into a suitable storage bin pneumatically via the air blowing through the discharge conduit 16.
The rotary valve 12 comprises a housing having a cylindrical body with an inlet at an upper end communicating with the outlet 14 in the floor of the container 4 and an outlet at a lower end communicating with the discharge conduit 16. As is known in the art, a rotor having a plurality of radially extending vanes is rotatably mounted within the cylindrical body of the housing of the rotary valve 12 for rotation about a substantially horizontal axis, the vanes being arranged to slidingly engage or closely sweep the inner walls of the body of the housing such that the rotor controls the flow of material from the container 4 into the discharge conduit 16 while acting as an air lock between the discharge conduit 16 and the container 4. This is required due to the pressure differential between the delivery conduit 16 and the container 4 when the main discharge apparatus 10 is in use.
A screw conveyor arrangement (not shown) may be provided in the rear end of the container 4 within channels in the floor of the container 4 for conveying material towards the outlet 16 in the floor of the container 4 and into the rotary valve 12.
The design of the rotary valve 12 of the main discharge apparatus 10, in particular the vanes of the rotor thereof, will be specific to the type of material expected to be transported by the vehicle. Typically the rotary valve 12 of the main discharge apparatus 10 will be adapted to deliver animal feed, which is the most common type of material required to be delivered by such vehicles, the vanes of the rotor of the rotary valve 12 therefore being formed from a rigid material, such as metal, and being arranged to create a relatively air tight seal with the walls of the body of the housing.
However, the design of the rotary valve 12 of the main discharge apparatus 10 will not be suitable for all materials that the customer may wish to have delivered by the vehicle. For example, a rotary valve suitable for handling animal feed will not be suitable for handling wood chips. This means that the vehicle must be considered to be suitable for use with only one type of material or must require costly and time consuming modification to replace the rotary valve 12 of the main discharge apparatus 10, in particular the rotor thereof, with one suitable for the specific material to be delivered.
In order to solve this problem a secondary discharge apparatus 20 is provided which can be detachably mounted on the rear wall 8 of the container 4 when required, the secondary discharge apparatus 20 being adapted for discharging a different material to that of the main discharge apparatus 10.
The secondary discharge apparatus 20 comprises a hopper 22 adapted to be releasably mounted onto the rear end wall 8 of the container 4, an inlet opening 24 of the hopper 22 fitting over the discharge opening 6 in the rear wall 8 of the container 4. A resilient seal 25 may be provided around the inlet opening 24 of the hopper 22 for forming a seal against the end wall 8 of the container 4 around the discharge opening 6.
As best illustrated in Figure 3, an elongate bar 26 extends along an upper side of the hopper 22 terminating in coupling spigots 28,30 at either end thereof, said coupling spigots being adapted to be received within receiving hooks 18 provided on either side of the rear wall 8 of the container 4 for mounting and supporting the secondary discharge apparatus 20 on the container 4.
The secondary discharge apparatus 20 further comprises a rotary valve 32 mounted in a lower region of said hopper 22 and provided with a driving motor. A transversely extending discharge conduit 34 is mounted below the rotary valve 32 for receiving material from the hopper 22 via the rotary valve 32. The discharge conduit 34 has an inlet union 36 at one end thereof coupled to a transfer conduit 40 which is in turn coupled to the outlet end of the discharge conduit 16 of the main discharge apparatus 10, when the secondary discharge apparatus 20 is mounted on the container 4, such that the discharge conduit 34 of the secondary discharge apparatus 20, when mounted on the trailer 4, is coupled to the blower of the vehicle via the transfer conduit 40 and the discharge conduit 16 of the main discharge apparatus 10.
The discharge conduit 34 of the secondary discharge apparatus has an outlet union
38 at an end thereof opposite said inlet union 36 to be coupled to a further delivery hose (not shown) for delivering material from the container 4 into a suitable storage bin pneumatically via the air blowing through the discharge conduit 34 of the secondary discharge apparatus 20. During use of the secondary discharge apparatus 20, the rotary valve 12 of the main discharge apparatus 10 is disabled/inoperative so that the discharge conduit 16 of the main discharge apparatus 10 merely serves to convey air from the blower to the discharge conduit 34 of the secondary discharge apparatus 20.
As discussed above, the rotary valve 32 of the secondary discharge apparatus 20 is adapted for use with a different material than that of the main discharge apparatus
10. As shown in Figure 6, in this embodiment the rotary valve 32 of the secondary discharge apparatus 20 is particularly adapted for use with wood chips, the vanes 42 having elastomeric tips 44 formed from rubber or polyurethane, such that the tips 44 of the vanes 42 can deflect should material become jammed between the tips 44 of the vanes 42 and the inner wall 46 of the rotor housing 48.
When it is desired to use the vehicle to transport materials for which the main discharge apparatus 10 is suitable, the secondary discharge apparatus 20 can be detached from the container 4. However, when other materials are to be transported for which the main discharge apparatus 10 is not suitable, the secondary discharge apparatus 20 can be quickly and easily mounted onto the rear wall 8 of the container 6 to permit the vehicle to be quickly adapted for transporting and discharging such other material.
The secondary discharge apparatus 20 constructed according to the present invention can be fitted as an attachment to any desired container 4 since this would require only simple mounting means which can be attached to the rear wall 8 of the container 4.
The secondary discharge apparatus 20 could also be provided with its own blower coupled to the discharge conduit 34.
The invention is not limited to the embodiment(s) described herein but can be 10 amended or modified without departing from the scope of the present invention.
