Abstract

The invention relates to agriculture and can be used when harvesting seeds of herbs with the collection of seed lots in the combine bunker. The purpose of the invention is to improve the quality of seeds. A seed pile is extracted from the canted crop, which with the help of an elevator enters the distribution auger through the receiving chamber. The loose seeds from the heap are poured through the slots of the casing and fall into the first section of the hopper. The rest of the seed heap auger transports to the second section. First, unload the second section. The unloading of seeds from the first section is carried out by gradual movement of one part of the visor in the direction of the other part after returning the last to the position when loading the bunker. 2 sec. and 2 z. p. f-ly, 2 ill.

Description

Yo

The invention relates to agriculture and can be used when harvesting seeds of herbs with the collection of seed lots in the combine bunker.

The purpose of the invention is to improve the quality of seeds.

Fig. 1 shows a combine harvester bunker for carrying out the method, a longitudinal section; figure 2 - section aa in figure 1.

The bunker has a housing 1, the bottom of which is made with inclined side walls connected below each other through a radial chute 2, as well as a lower discharge device in the form of a screw 3 placed in chute 2, a housings placed above the screw 3 and made of two different . hinged in height moving parts 4 and 5, the edges of which are placed in guides

6 mounted on the side walls of the bunker, distribution screw 7, the beginning of which is located in the receiving chamber 8 connected to the output part of the elevator 9, and the partition 10 installed in the bunker perpendicular to the axis of the distribution screw 7. The partition 10 divides the bunker into two sections 11 and 12. The distribution screw 7 in the first section 11 is enclosed by a cylindrical casing 13 made in the form of a sieve. The casing 13 may be provided with a drive (not shown) of rotation in the direction opposite to the direction of rotation of the screw 7. Drives movable parts 4 and 5 along the discharge screw 3 are provided with actuators made in the form of hydraulic cylinders 14 and 15, respectively, which are connected to the hydraulic system (not shown) combine.

ABOUT

oh oh

 The proposed method is carried out using this bin as follows.

From the crop of crops harvested or harvested from the floor, for example, clover, the seed heap is extracted, which with the help of an elevator 9 enters the distribution auger 7 through the receiving chamber 8. The free seeds from the heap are poured through the slots of the casing 13 and enter the first section 11 bunker. The rest of the seed pile, consisting of non-dried seeds and various plant impurities, is transported further by the screw 7 to the second section 12.

By rotating the casing 13, its openings are less clogged, and the opposite directions of rotation of the casing 13 and screw 7 provide better mixing of the pile.

Selected in section 11, the free seeds are unloaded separately from the rest of the pile. Section 12 is first unloaded, for which, when the 3 auger is on, part 4 of the visor is gradually moved under part 5. Unloading seeds from section 1 is gradually moving part of the visor 5 towards part 4 after the latter is returned to the position when the hopper is loaded.

Such an unloading of the bunker allows to collect separately free seeds into vehicles, which do not require (or require less) post-harvest treatment, and seed heaps, as a rule, of high humidity.

Separating free seeds from a pile before entering the bunker reduces the moisture content of seeds by reducing the time they come in contact with impurities, which reduces the cost of processing seeds and improves their quality.

Claims (4)

1. A method of combine harvesting of grass testes, including the isolation of seed seed from the crop, feeding it into the bunker sections and subsequent unloading of them, characterized in that, in order to improve the quality of the seeds, in the bunker when feeding the heap into the section the free seeds, which are collected in one of the sections, and the subsequent unloading of free seeds is carried out separately from the rest of the heap. 2. A device for combine harvesting of grass testes, comprising a housing mounted in it a lower discharge device, an upper distributor jaw, the initial part of which is placed in the receiving chamber for a pile fed to the bunker, and a partition installed perpendicular to the screw axis into two sections of the bunker cavity, characterized in that the hopper is provided with a cylindrical lattice cover covering the screw section located in the section adjacent to the receiving chamber. 3. The device according to claim 2, wherein it is provided with a drive for rotating the housing around the axis of the screw. 4. The device according to Clause 3, characterized in that the directions of rotation of the casing and the screw are opposite. LT G 4 at c i- cii I j I five
