The invention relates to a threshing machine, in particular for threshing legumes, with a - preferably rotating - sieve drum and with arranged inside the sieve drum, rotating beater blades, which act on the material to be viewed and it against the sieve drum throw, in which a conveyor mat running diagonally upwards is arranged below the sieve drum which fruit emerging from the sieve as well as particles of the threshed through the sieve Good fall and which have such a surface texture that the fruits roll on them, however, the straw particles are lifted up by them.

A pea husking machine is known in which a sieve drum is inclined upwards below a sieve running conveyor mat is arranged on which the peas against the conveying direction in a trough can roll while the pod waste is transported upwards. The disadvantage here is that the peas can fall from the conveyor mat here, in particular can bounce off this, like this that they do not get into the collecting trough. Furthermore, the known machine does not allow a continuous Operation, as the peas cannot be continuously removed from the collecting trough.

The invention is based on the object of creating a threshing machine of the type mentioned at the beginning, in which with certainty all legumes emerging from the sieve drum into the intended Catcher are directed. This is achieved according to the invention in that below the Sieve drum symmetrically to a vertical plane laid through the axis of the sieve drum two obliquely upwardly running conveyor mats are arranged, which form an open channel at their bottom, below which is arranged a collecting channel for the fruits.

Legumes that fall out of the sieve drum and hit one of the conveyor mats bounce off it away. However, you then do not fly out of the threshing machine, but either fall through it through the lower ends of the conveyor mats or onto the conveyor mat from which they have bounced back or on the other conveyor mat. As a result, all of the legumes are down through the space Discharged between the lower ends of the conveyor mats. The conveyor mats work in this sense with the sieve drum together and also with each other.

The invention is explained in more detail below with reference to the drawing using an exemplary embodiment. In the drawing shows

In Fig. 1, 22 denotes the sieve drum of the threshing machine, which with the help of rollers 23, the abut against the outer surface of the drum disks 26 and 27, of bearing points 20, of which only one is shown to be worn. The drum consists of longitudinal strips 30 or 54 and circumferential strips 56 (Fig. 3), between which the spaces 58 with wires 60 and 62, which are preferably made of elastic Are made of plastic, are covered. For example, networks 65 (Fig. 5 and 6) are stretched here, their Edges are piped with edge strips 67.

Claims (1)

A beating drum 32 is arranged coaxially within the drum 22 and is rotatably mounted. These Beating drum 32 is driven by a drive, not shown. The beating drum consists of a cylinder 34 with impact vanes 36. It is mounted with the aid of stub axles 36. Through the Beating drum 32, the pods of the legumes are broken open and together with the fruits and hurled with pieces of straw against the nets 65, which let the fruit through and the rest But essentially hold back parts. Below the sieve drum 22 are two symmetrical to a vertical plane passing through its axis Conveyor mats 41 and 42 are arranged, the parts of which are denoted by 43 and 44, which move obliquely upward are. The legumes 46 passing through the sieve drum 22 coincide with any Pod and straw parts on the obliquely upward moving parts 43 and 44 of the conveyor mats 41 and 42, these are set so that the legumes 46 roll down while the pods and pieces of straw are taken up and thrown off in the lower run of the conveyor mats will. The conveyor mats 41 and 42 form an open channel on their sole as, below which a collecting channel 50 is arranged for the fruit. Claim: Threshing machine, especially for threshing legumes, with one - preferably rotating - sieve drum and with arranged inside the sieve drum, rotating Impact shovels, which act on the crop to be threshed and throw it against the sieve drum, in which a conveyor mat running diagonally upwards is arranged below the sieve drum, on which fruits emerging from the sieve as well as particles of the threshed out through the sieve Guts fall and which have such a surface texture that the fruits roll on them, but the straw particles are conveyed up through them, characterized in that below the sieve drum (22) symmetrically to a vertical plane laid through the axis of the sieve drum two Conveyor mats (43,44) running obliquely upward are arranged, which have an open at their sole Form a channel below which a collecting channel (50) for the fruits is arranged.
