CS231950B1 - Apparatus for seeds cleaning in a harvester bin - Google Patents

Abstract

The device is intended for partial removal dirt from threshed seeds in the harvesting machine magazine. Above the day the hopper and along its side the wall is inside the folding tray perforated bottom and perforated side wall. Between the bottom of the hopper and a side wall is arranged to be dropped Dirt slot.

Description

BACKGROUND OF THE INVENTION The present invention relates to a seed cleaning device in a container of a chuck.

The existing agricultural ski and harvesting machines, in particular cereal combine harvesters, do not achieve good parameters in harvesting pulp and other seeds in which undesirable admixtures often occur. For this reason, after harvesting, the seeds need to be refined, which is a difficult and costly operation.

The seed cleaning device in the container of the chuck of the present invention substantially alleviates this disadvantage. It consists in that a perforated bottom and a perforated side wall are arranged above the bottom of the tipping container and along its side wall, and a discharge dirt slot is arranged between the bottom of the tipping container and the side wall.

The seed cleaning device in the container of the harvesting machine according to the invention brings about a substantial increase in the purity of the threshed seeds transferred from the container of the harvesting machine to the conveying means, making it possible to significantly shorten, make productive and cheaper the additional post-cleaning process.

An exemplary embodiment of the device according to the invention is shown schematically in the accompanying drawing, in which Fig. 1 shows a side view of the device in the basic position, Fig. 2 shows a side view of the device at the beginning of tilting;

The tilting seed hopper 4 is articulated by means of a hinge 4 to the machine frame 6. A linear motor 4, e.g. a hydraulic motor, articulated at its other end with a tilting container 6 is also articulated to the machine frame. Above the bottom of the tilting container 4 and along its side wall J which is provided on the tilting side, a perforated bottom 4 is arranged inside the tilting container 4, extending into the perforated side wall 4 extending up to the edge 3 of the tilting container 4. 3 of the tipping container 4 and the side wall 3, a discharge dirt slot 10 is provided. The tilting hopper 8 is arranged on a ski and harvesting machine (not shown) at the point of delivery of the threshed seeds.

The plant according to the invention operates as follows: The seeds are fed to the tipping container 4 at harvest and fall onto the perforated bottom 4, through which impurities fall directly onto the bottom of the tipping container 4, in particular from the beginning of filling the tipping container. As the machine moves across the field, the hopper 4 shakes the seeds and the contaminants fall to some extent into the bottom of the hopper 4 and through the perforated bottom 4 to the bottom itself. At the beginning of the tilting, which is effected by the linear motor 6, the tilting container 8 is bent and its bottom 2 is tilted. Dirt, which has fallen onto the bottom of the tilting hopper 8, falls down to the discharge slot 10 and falls outside the machine. Upon further tilting up to the extreme tilted position of the hopper 4, the seeds are poured onto and out of the perforated sidewall 8, but at the same time impurities fall down and fall through the perforated sidewall 8 onto the hopper sidewall itself. get out. Upon returning to the position shown in FIG. 2, the dirt will fall from the side wall 6 into the discharge slot 60 and fall out of it, so that in the basic position the tilting hopper 6 is cleared of the dropped dirt and able to receive further threshed seeds. Thus, the perforated bottom 4 and the perforated side wall 8 fall through and outside the harvested seeds considerable amounts of impurities are obtained which would otherwise have to be separated in an additional working process.
