Description

Description

The innovation relates to a vehicle for receiving and storing flowable Bulk goods «it is a transport container to hold the bulk goods as well as a first screw conveyor arranged in the bottom area of the transport container for the forced emptying of the container.

Such vehicles are used, for example, in agriculture used, fertilizers in the form of dust or granules, animal feed, To transport and store grain, sugar beet pulp and the like. So far, these goods have been placed directly on trailers, e.g. in agriculture, in containers placed on trailers or transported or temporarily stored on tipping trailers. These vehicles or containers are emptied by hand or by means of a screw conveyor provided in the bottom area of the transport container. It is not yet known to produce these goods from the Pulling off the vehicle or the container and at the same time moving it upwards in such a way that they can be transferred to other containers or the like, e.g. the receptacle of a fertilizer spreader. There are therefore so far to fill such containers to carry out lengthy transport work by hand.

The object of the present invention is to create a transport vehicle for receiving and storing flowable bulk goods, which can easily be emptied by machine and the transfer of the bulk material in it in a second container or the like, e.g. in a fertilizer spreader. The vehicle should be particularly suitable for agricultural use.

This object is achieved in that the first A second screw conveyor is connected downstream, which is in a rear end of the transport container to both a horizontal as well as un a vertical axis pivotably articulated conveyor pipe is arranged that both conveyor screws nit one each The output shaft of a transmission driven by a cardan shaft are coupled and that one of the arranged in the transport container first screw conveyor shaft connected in parallel one of the two output shafts of the gearbox nit the second screw conveyor via a Universal joint connection connects.

The pivoting mounting of the delivery pipe enables a quick Aligning the dispensing end of this tube with respect to a receiving opening or the like of a receiving container. This will be tedious maneuvering movements superfluous. The two output shafts of the transmission provided according to the innovation are used to drive the first screw conveyor located in the transport container and the parallel drive second screw conveyor arranged in the conveyor pipe. This enables the second screw conveyor to rotate more rapidly to be given as the first, un in this way at the transfer point between the first screw conveyor and the second screw conveyor to exclude a backlog of material and thereby particularly strong signs of wear.

The invention further provides that a tubular bellows movable in all directions between an outlet opening at the rear end the first screw conveyor and the inlet end of the conveyor tube of the second screw conveyor is provided. This way it becomes dust free Transfer of the material from one screw conveyor to the other

made possible without thereby reducing the freedom of movement of the conveyor pipe is restricted in a disruptive manner.

Furthermore, the innovation suggests that the transmission outside of the transport container is arranged. It is therefore easily accessible and protected against the sometimes aggressive bulk materials. In the same sense, a further suggestion of the innovation works, accordingly the shaft for driving the second screw conveyor is arranged under the transport container.

Finally, the invention also proposes that the universal joint upstream of the second screw conveyor should be outside the transport container and is arranged outside of the conveyor pipe. The heavily used parts of this joint are made this way not contaminated or attacked by the bulk goods concerned. The trouble-free operation of the entire vehicle will also further secured in this way.

In the following part of the description, an embodiment of the vehicle according to the innovation described with reference to drawings. It shows:

In the embodiment of the innovation according to the vehicle according to the 1 to 3 is a single-axle trailer which has a frame 1 with a drawbar 2 and two running wheels 3 having. The frame 1 carries a transport container 4 with a roof 5. In the roof 5, a ventilation nozzle 6 is provided. Furthermore, a filler neck 7 for a pneumatic one opens in the roof area Filling of the container 4. It is of course possible to use the transport container 4 without a roof 5, if this is the case The type of bulk goods to be transported or stored as well as the weather conditions permit. The frame 1 is in the exemplary embodiment connected with three height-adjustable supports 8, which keep the vehicle in the parking position even on uneven ground Hold it securely while relieving the impellers 3.

As FIG. 2 shows in particular, the transport container 4 is a when looking in the longitudinal axis of the vehicle, the lower section 9 tapers downwards in a U-shape. Forms in the lower area he a channel, in vi / elcher a first screw conveyor 10 arranged is. The axis of this first screw conveyor 10 runs centrally in relation to the vehicle frame in the vehicle longitudinal direction.

The first screw conveyor 10 is at least in the area of a front wall 11 and a rear wall 12 of the transport container 4 are rotatably mounted. Your in the direction of the drawbar 2 from the transport container 4 protruding end is connected to an output shaft 13 of a transmission 14 shown schematically. This gear 14 is connected to a cardan shaft 15, which produce a drive connection to a tractor, not shown can.

The transmission 14 has a second output shaft 16, which is connected to a

of the transport container 4 arranged shaft 17 is coupled.

A universal joint connection 18 connects to the rear end of the shaft 17. This universal joint 18 includes a transmission shaft 19 which is on the one hand non-rotatably coupled to the ^w elle 17 and on the other hand with a worm shaft 20th The screw shaft 20 carries a second screw conveyor 21 within a conveyor pipe 22. A tubular bellows 23, movable in all directions, establishes a connection between the outlet opening of the first screw conveyor 10 in the rear wall 12 of the transport container 4 with the inlet end of the conveyor pipe 22, which enables this conveyor pipe 22 to pivot enabled. The mounting of the conveyor pipe 22 is made so that it can be pivoted both about a horizontal axis running parallel to the wheel axis and about a vertical axis.

The inclination of the conveyor pipe 22 is determined by a pull rope 24, About a pulley 25 in the upper area of the rear wall 12 to a Cable drum 26 with crank 27 runs.

The charging of the vehicle according to the innovation can be carried out pneumatically the filler neck 7 take place. If the transport container 4 is open at the top, it can also be loaded by means of a lift truck, front loader or e.g. directly from the combine harvester into consideration.

The transport container 4 is emptied via the two screw conveyors 10 and 21 connected in series, with the flow of force for driving the second screw conveyor 21 not over the first Conveyor screw 10 is performed, but starting from the second

Output shaft 16 of the transmission 14 leads over the shaft 17. In this way it is readily possible to give the second conveyor screw 21 a greater Uadrehungszahl than the first and so that the bulk material at the transfer point between the first screw conveyor 10 and the second screw conveyor 21 located in the transport container 4 abzufordern faster than it is supplied to this point, . In this way, a backwater and a harmful grinding effect can be eliminated. It has proven to be useful to let the second screw conveyor run about three times as fast as the first screw conveyor 10. The optimal speed ratio between the two screw conveyor 10, 21 depends on the bulk goods that can be considered in each case and can also be changed as a result, that the two screw conveyors 10, 21 do not have the same pitch.

The bulk material located in the transport container 4 can therefore without Difficulties are transferred to other containers or the like, for example also in the receptacle of a fertilizer spreader. Disturbances when emptying the transport container 4 are not to be feared.
