In the known seed drills with a large working width, the one arranged transversely to the direction of travel has Large capacity seed box. In this seed box, the seeds are usually filled from sacks, some of which weigh around 100 kg. When filling in the seeds, the worker holds the sack open the back and lets the crop gradually run into the seed box. But at the same time he has to pay attention Make sure that the sack does not get so deep into the container that it is removed from the sacks at the bottom of the container Stirring tools is detected. Since this work requires very great physical strength, the The invention is based on the object of facilitating the filling of the seeds from the sacks into the seed box.

This is achieved according to the invention in that in the seed box below the upper edge of the seed box a support or storage device for a storage bag filled with seeds is arranged, which as a grid consisting of spaced apart rods or designed as a grate. at with a seed box equipped with such a grid or grate, the sack can slide over the edge of the seed box thrown and placed on the grate and then the seeds are pushed out of the sack or scraped out or the sack opened at the bottom so that the seeds run out of it can.

It is true that a spreader for fertilizers such as lime and the like has already become known, with which in the container below the upper edge of which a sieve box is arranged. This sieve box is intended to to separate out any impurities in the almost powdery fertilizer. It therefore consists of a fine-mesh sieve. However, such a fine-meshed sieve cannot provide the required Have strength to carry a sack of about 100 kg filled with seeds. In addition, is suitable Such a sieve therefore not to solve the problem underlying the invention, since the fine sieve meshes would prevent or at least make it considerably more difficult for the seeds to pass through.

Although a stiffening device on such seed boxes has become known, which from between the two longitudinal walls of the seed box arranged struts. However, these strivings are so sparse attached that the open end of a sack deposited thereon between the struts through on the The bottom of the seed box fall and can be detected by these attached agitators.

All these known devices can therefore not serve the purpose of those arranged according to the invention Meet storage device. According to a development of the invention, the storage device for

the rods forming the seed sacks can be arranged in the longitudinal direction of the seed box. The grid or the The grate can also be carried by plates that are attached across the seed box and reinforce it have roughly the same function as the previously described known stiffening device consisting of struts.

Further details and advantages of the invention emerge from the following description of the in the embodiment shown in the drawing.

Fig. 1 shows a side view of the seed drill, the seed box of which is shown in section;

Fig. 2 is a top plan view of the seeder without the seed box cover;

Fig. 3 shows the machine in an oblique view with the seed box open.

The transverse to the direction of travel extending seed box 1 of the machine shown has a hinged cover 2 and is attached at its ends in the frame of the machine. This frame has side supports 3 which are connected by means of supports 4 to a catwalk 5 attached to the rear. The catwalk preferably consists of sheet metal welded to one another in the form of a box, in order to thereby form a rigid carrier which, together with the seed box and other cross members 6, stiffens the frame against rotation. However, this formation of the catwalk is not the subject of the invention. As usual, the machine has running wheels 7

and a tie rod 8 (drawbar) connected to the frame. In the lower part of the seed box there is, as usual, a shaft 9 provided with agitator arms and outlet openings (not shown) for the seed. The seed box contains stiffening plates 10 running transversely to the seed box. In the upper part of the seed box the rods or supports 11 forming the storage device according to the invention are arranged, which rest on the stiffening plates 10 or are firmly connected to them, but can also be firmly connected to the seed box walls. In the example shown, these rods extend in the longitudinal direction of the seed box and thus parallel to the agitator shaft. The number of rods 11 can be chosen differently. As already mentioned, these rods 11 form a support and shelf for the sacks to be emptied into the seed box. The rods are attached at a certain distance below the upper edge of the seed box, but at a considerable distance above the agitator shaft 9. In the exemplary embodiment there is a bar grate at each end of the seed box, while a part 12 of the seed box opening is left free between the two grids. In the illustrated embodiment, as can be seen in FIG. 3, the several bars, existing grids or grids are stored in the seed box so that they can be folded up so that the organs present in the seed box below can easily be reached if necessary. The rods 11 are held together by transverse rails 14, the outer ones of which are arranged in such a way that they rest on the upper edge of the stiffening plates 10 when the grate is folded down. In Fig. 3 a lying on the grate full sack is shown, from which the seed is emptied into the seed box. Godfather ν τ α ν s ρ rccη ε. 1.
