(54) SEPARATING-TRANSPORTING DEVICE TO THE CLEANING MACHINE

I

The invention relates to agricultural machinery, in particular, to separating and transporting devices of harvesting machines intended for harvesting of root and tuber crops or stones from the floor.

Known transport device-. The property to the harvester contains a digging blade, a conveying grating with a rotating beater, and a rotor with radial fingers located above the grate in front of the beater.

However, in the known device, the conditions for transporting and separating a soil layer are not sufficiently effective, since jamming and plugging of the transport grid is observed in the soil layer.

The purpose of the invention is to reduce the clogging of the device by the soil when the soil layer is moved.

The goal is achieved by the fact that the rotor's fingers are located along the

adherent to its surface and deflected in a direction. opposite to the movement of the soil layer along the transport grid.

In addition, the device is equipped with an additional rotor located above the grate behind the beater, while the front rotor is fixed with the possibility of swinging movement relative to the additional rotor and is spring-loaded.

FIG. 1 shows a separating transport device to a harvesting machine, side view; in fig. 2 - also, top view; in fig. 3 - 6 - scheme of the rotors.

The separating-transporting device to the harvesting machine comprises a plowshare 1 with a grill 2, a forward rotating rotor 3 with fingers 4, a rear feeding rotating rotor 5 with fingers 4, a rotating beater 6, as well as a drum-type separator 7 and a bunker 8 of the cleaning machine. The front part of the grid is attached to the share pivotally on the axis 9, the rear part is included in the separating device 7, the rotors are located above the blade and the top of the grid. The fingers of the front feed rotor combs are located tangentially to the circumference, and the fingers of the rear feed rotor combs are radially, with both rotors arranged so that the fingers of one of the rear rotor combs are engaged with the fingers of one of the front rotor combs, forming the contact L1shsho along the entire length of his fingers (Fig. 36), Rear feed rotating rotor 5 is mounted on frame Yu, which is hinged to the frame of the machine, and the front rotor is mounted on frame 11, which is hinged to the rear rotor axis and is suspended by means of elastic elements 12 to the rear frame 10 of the rotor 5,

Bottom under the picking grid, the rotor has a rotating beater, which is the working part for grinding the soil layer and transporting the stones along the grid. The front feed rotor is made with a large number of combs than the rear feed rotor, as many times as the rotational speed of the front feed rotor is less than the rotation speed of the rear feed rotor,

The device works as follows.

When the machine moves the plowshare 1, recessed to the specified depth, it separates the reservoir and feeds it to the grid 2. The front feed rotor 3 rotates along the machine and with its fingers 4 moves part of the reservoir along the spring to the grid 2, partially separating it and rotating it against , the stroke of the beater 6, which crushes and separates the soil environment, as well as fansport stones along the grate, the rear feed rotor 5 rotates along the machine and with its fingers 4 removes mass from the front feed rotor fingers, directing it to the device 7, Fingers The rotors are made of Prussian steel, which ensures their self-cleaning and deflection in case of overload. The soil, crop residues are crushed and sieved with a beater 6, and the stones with the remaining soil are transported by the rear feed rotor to a separating device 7 of the drum type, from where the cleaned stones are sent to the bunker 8. Emptying the hopper is done with

help; hydraulic ram to the vehicle.

When overloading the feed rotors, when they encounter obstacles (large stones and other large objects), the rear feed rotor is raised with the help of frame Yu, which is pivotally connected to the frame of the machine, and the front feed rotor is raised with

0 by means of a frame 11 pivotally connected to the axis of the rear feed rotor by compressing elastic elements 12 connecting the frames of the two feed rotors. Front rotation speed

5 feed rotors are so many times smaller than the rotational speed of the rear feed rotor, how many times the number of combs of the rear rotor is less than the number of front rotor combs, at the result of which the engaging rotor combs form a contact line along the entire length of the front-rotor comb pins, that without blockage and jamming. Besides

In addition, the rotation of the rear rotor at a faster speed than the speed of rotation of the front rotor contributes to better crushing of soil lumps and their separation. Stone Harvest Designs

0 can be semi-mounted or trailed.

The proposed device allows to increase productivity and reliability, to improve the separation and technological process of cleaning. Two feed rotors, located above the pick-up grid, ensure uniform feeding of the mass without clogging, crushing of soil lumps and their separation.
