The invention relates to a device for dispensing a powdery or granular substance used in agriculture and forestry, the device comprising a tank mounted on a chassis, e.g. a tractor and a trailer, which may be provided with a tipping device for tilting the tank and a second tank mounted on the rear of the tank. the device being further provided with a feed screw 11a with filling devices or similar means for conveying the powdered or granular goods.

The above-mentioned device for dispensing powdered or granular goods can be considered to be known from DE-patent 572 164 and from solutions known from DK patent 105 838.

DE-A-572 164 discloses a manure application device which comprises two successive containers in the direction of travel of the device, the rearmost of which must be opened. According to a German patent, the lid of the rear container is openable, 2 62199 whereby in its open position the operating platform is arranged between the containers in the operating spirit. The tanks are not in direct contact with each other.

DK patent 105 830 discloses an artificial fertilizer application device comprising a hopper and a conveyor screw placed on the bottom of the hopper for transferring the artificial fertilizer placed inside the hopper to the application nozzle at the rear of the device.

The prior art conveying and dispensing devices described above, which have a container which is filled with a transportable and dispensable substance, which is then fed through means and devices connected to the container to the intended destination for application, has the disadvantage of filling said container. In the case of small devices in which the tank is correspondingly small, the grievance is not yet harmful. Instead, if the equipment is large, such as lime spreading equipment. in agriculture, especially for large fields, it may take an unreasonable amount of time to fill such a device with the material to be applied. In the case of often transferring an entire truckload to the tank of a device, various methods and devices have been developed for this purpose.

It is known, for example, to use pressure equipment. However, this method has proven to be a relatively pool in practice. Other known devices also have the same drawback, such as screw conveyor-grab devices or other types of conveyor and transfer devices between the truck and the spreading device.

This disadvantage results in a large waste of time, which causes unnecessary costs and impairs the efficiency of the use of the equipment. It should be noted that the trucks used to transport the material to be applied and the equipment used to apply the material are quite expensive, so their operating costs are also high. When both 3 62199 have to stand during filling, there is correspondingly less effective working time.

The object of the invention is to eliminate the above-mentioned drawback by providing an improved device according to a species definition, the filling of which can be carried out much faster than previously known. In this case, the downtimes of both the trucks used for transport and the distribution equipment itself are reduced and the effective operating time is correspondingly increased, so that it is possible to handle larger areas than before.

The invention is mainly characterized by what is set forth in the characterizing part of claim 1.

The invention is further illustrated in the following description with reference to the accompanying drawing, in which Fig. 1 shows a side view of a device according to an embodiment of the invention, Fig. 2 shows a container part of the device,

The device according to the invention has a running platform, such as, for example, a tank 1 fitted to the tractor and its trailer, which is arranged in a manner known per se by means of tipping devices on the platform of the trailer.

The container has an elongated shape and a V-shaped or W-shaped cross-section so that the granular or powdery substance to be dispensed or applied from the container flows better into the container bottom chute or chutes 2, to which conveyor members, e.g. chain conveyor 3 or the like, are placed. , which serves to supply the substance to be applied from the container to the distribution pipes 4 at the front of the container. These distribution pipes protrude laterally from the front of the container to a suitable length and their outer parts 5 are made to fold and pivot to the side of the container. The distribution pipes are fitted with transfer screws which are adapted to transport the material to be fed into the pipes. A similar liquid motor also uses chain conveyors 3. Holes of suitable size are made in the tubes 5 below them, from which the substance to be applied falls down as a thin jet.

According to the invention, a feed tank 6 is arranged in its rear part for filling the tank 1, which is separated from the tank 1 by the rear wall of the tank 1. The feed tank 6 communicates with the actual tank 1 only through a feed pipe 7. Through which powdered or granular material is fed to the tank 1. to meet. Inside the supply pipe are fitted the feed screw 9 used by the stem motor n 8, by means of which the substance is transferred to the tank 1. The supply pipe 7 has an opening in the middle through which the substance enters the pipe. There are one or more pipes 7, preferably two pieces, mounted side by side, each of which feeds into its own trough at the bottom of the pipe.

According to the invention, the feed container 6 can be fixedly attached to the container 1 or can be tilted backwards relative thereto.

If the feed container 6 is fixed with respect to the container 1, it is most preferably set in a somewhat backward tilted position, whereby the rear part of the container 6 becomes considerably lower relative to the bottom of the container 1. This has the advantage that when pouring the material to be spread from the truck platform, the load can be tipped directly into the feed hopper 6 without having to tilt it by means of its own tipping vessel. One or two further support legs 10 can be arranged at the rear edge of the feed container b, which rest on the ground and support it during the filling of the container.

The feed tank 6 can also be made laterally spreadable, which has the advantage that a load can be tipped into the tank from a very wide truck platform. This also speeds up the filling time of the tank, making it easier to reverse the truck to the rear of the tank. The lid halves 11 of the container 6 can be turned vertically to the side during filling, so that the fine cannot affect the fine-grained material.

By using the feed tank according to the invention, the filling of the tank can be carried out very quickly, and no separate transfer devices are required to transfer the substance from the truck to the tank. When the load is poured into the feed tank 6, the screw conveyors quickly take it to the actual tank 1. The truck is immediately released and the spreading device is immediately free for spreading work, even if part of the poured load is still in the feed tank. The supply container is further advantageous in that it acts in a way as a kind of spare or additional container, whereby the container 1 can be filled first and then the supply container 6 can be further filled. Thus, the spreading capacity of the device is increased.

It is natural that various constructions may take place within the scope of the invention. Thus, instead of screw conveyors which convey the substances from the feed container 6 to the actual container 1, other conveyor means known per se, such as, for example, belt, coulter, towing, hollow conveyors and the like, can be used.
