Abstract

The invention relates to agricultural machinery and is intended for use in combine harvesters. The purpose of the invention is to improve the quality of cleaning the deck. The device contains mounted on the rotor 2 brush elements 4, made sectional. Each section is spring-loaded in the radial direction by means of springs 5. On the outer side of the deck, additional brush elements 8 are installed. When the casing 1 sticks, the brush elements 4 located on the rotor 2 are transferred from the inoperative position to the working position and fixed by means of the stops 7 to the rotor surface . During the rotation of the rotor, the sections of the brush elements are in contact with the surface of the casing, with this, due to the prune of the brush, they oscillate. When brushing elements 4 are touched, additional brush elements 8 are introduced through the holes of the deck prior to interaction with the latter, resulting in cleaning of the brush elements. 3 il.

The invention relates to agricultural machinery, in particular to devices for threshing and separation of a heap of grain, and is intended; for use in combine harvesters.

The purpose of the invention is to improve the quality of cleaning the deck.

FIG. I shows a threshing and separating device with a cleaning device; Fig.2 multi-sectional brush element; nafig.Z-paths of movement of tape sections; items.

j The threshing and separating device consists of a separation casing 1, IpoTopa 2 with scourges 3, and on the rotor 2 there are ball-shaped brushes 4 fixed to the rotor 2, consisting of 5 sections 6 mounted on springs, each brush element is provided with a stop 7, an additional multi-brush elements 8 sectional are located outside the skin- | xa 1. The latter are fixed on the guide pads 9, which are pivotally fixed on the side panels of the threshing-grinding device 10, the brushes are equipped with adjusting strips 11. I The proposed device works | as follows.

 When the internal surface of the IIOCTH separating casing is 1 sticking, there are 1 brush elements located on the roto ™

;) e 2, are transferred to the working position of the elements, each section of the grip is fixed by means of stops 7 to the surface of the rotor 2. When the rotor rotates, the section 6 of the brush elements are in contact with the inner surface of the casing 1, at the expense of pr40

the exact elements are spring-loaded in the radial direction, and additional brush elements are mounted on the outer side of the deck so that additional brush elements can be placed in its openings.

Life 5 they fluctuate. When sticking the brush elements manually or automatically moves the adjustment bar 11, thereby moving along the guide bar 9 additional multisectional elements 8, which enter the openings of the casing 1 before contact with the brush elements t SH 4. When the rotor 2 rotates, these brushes from stuck in them grains, particles of straw, chaff. After the cleaning of the brush elements 4 is completed, additional brush elements are removed from the casing I. After the cleaning of the casing 1 surface is completed, the brush elements 4 are attached to the surface of the rotor 2 in an inoperative position.

Claims (1)

Invention Formula A device for cleaning the threshing device on a separating device, including a brush cleaner installed on the rotor between the whips along its axis and with the ability to interact with the deck, equipped with a fixing mechanism in the workplace and off positions, characterized in that, in order to improve the quality of the cleaning of the deck, the brush cleaning agent is made in the form of several sectional 40 the exact elements are spring-loaded in the radial direction, and additional brush elements are mounted on the outer side of the deck so that additional brush elements can be placed in its openings. phi.2 CpL / g.Z.
