Description

The invention relates to agricultural machinery, in particular, to seed structures of harvesting catchers, and can advantageously be used for harvesting easily perennial grasses, as well as leguminous crops, in particular peas.

A grain collector for harvesting machines is known, including an i.e. with a removable grill consisting of longitudinal slats, and in the side wall of the chic has a discharge opening, closed by a shield 1.

The disadvantages of this device are significant losses of seeds of perennial grasses during harvesting, large labor intensity and time spent on unloading seeds from the device. This is due to the fact that the main part of the seeds, which is inside the velocity mass, hangs in it or does not succeed to be separated during the time it passes through the crate of the box and, together with the velocity mass, is placed in the swath and falls to the ground. In addition, the accumulated seeds are manually removed through a hole in the side wall. into any container, while there are also losses of seeds due to spilling them on the ground, especially in windy weather.

The grain collector of the harvesting machine is known, which contains a seed separator with a container installed under it, the bottom of which is connected by means of a suction-driven pneumatic actuator to a storage unit n 2

The losses of seeds that a known device permits are due to the insufficient effectiveness of the pneumatic effect on the mass to be cleaned. The greatest intensity of air flow to the mass to be trafficked is observed in the zone of connection of the pneumatic actuator to the container and decreases as it moves away from it. Moreover, in some areas of the separating surface, the pneumatic effect does not have a significant effect on the release from the mass of showered seeds. Irregularity of pneumatic over the area of the separating surface does not allow to create an optimal pneumatic mode, and insufficient intensity of air flow on a part of the separating surface impairs the separating ability of the seed catcher, increases seed losses in the process of planting the rolls.

The known device is complicated in construction; mechanical conveyors (chain-slatted and screw), having their own drives, are used to collect spilling seeds. The presence of these conveyors increases the metal capacity of the device, reduces reliability in operation, and also increases its overall height, especially in the case of using this catcher with harvesting machines such as self-propelled

MOWER EY-301, as this catcher in this case is located under the mower-conditioner. The overall height of the catcher in this case is limited by the clearance of the harvester.

The purpose of the invention is to increase the efficiency of the release of seeds from the harvested mass by increasing the pneumatic effect on it.

The goal is achieved by the fact that in the device the bottom of the container is made corrugated and having holes made in the hollows of the corrugation, each of which communicates with the pneumatic conduit.

FIG. Figure 1 shows schematically the proposed sem catcher with a separator made in the form of an infinite moving surface; in fig. 2 - the same with a separator, made in the form of an oscillating greping board; in fig. 3 - part of the bottom of the tank with a pneumatic line divided into a number of hoses; in fig. 4 - part of the bottom of the tank, in a perspective view.

This catcher is installed behind the unloading window of the header 1. It can be attached to it and lean on support wheels or skis (not shown) or attached to the self-propelled mower from below. This catcher contains a separator 2, which can be made, for example, in the form of a chain conveyor with elliptical asterisks 3, the chains of which are connected by rods 4 forming a separating surface (Fig. 1). When harvesting individual crops, the rods 4 may be covered with a mesh with the required cell size. The separating surface can also be made in the form of a flat oscillating grappling sieve 5 (Fig. 2). Under the separator 2 there is a container 6 for collecting seeds isolated from the beveled mass, having a corrugated bottom 7. In the valleys of the corrugation, through holes 8 are made round or in the form of slots. A pneumatic actuator 9 is connected to the bottom 7 and connects it to the accumulator 10 and the fan 11. The pneumatic actuator 9 is connected to the bottom 7 in the form of a series of hoses with walls 12.

The device works as follows.

In the process of mowing and laying in an agricultural crop, the folded mass is fed through the unloading window of the header 1 to the separator 2, which is transported, above the tank 6. The descent from the separator 2 is put into the roller. During the passage of the ground mass above the tank 6, it is subjected to mechanical action (shaking) from the side of the separator 2 and pneumatic effects (sucking air through it) from the side of the seed collection system, including
