Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to corn harvesters. The purpose of the invention is to increase the reliability of the process. The mace picker consists of rotating pulling rollers 2. Above them, by means of elastic elements 3, stripper plates (SP) are mounted for movement in a plane perpendicular to the axis of the rollers. SP installed at an angle to each other, the top of which is directed upwards. The device has stops 6, limiting the movement of the joint venture, and the drive oscillations of the joint venture in the same phase. When the combine is moving along a row of maize, the stalks are inserted between the rollers 2 and the LP and are pulled down. The elastic elements 3 are compressed and thereby weaken the force of the stroke of the cob against the joint venture. At the time of the cob separation, its contact area with the joint venture increases. Installing the joint venture at an angle to each other provides automatic change of the gap between them. During the period of pulling the lower part of the stem, the gap is maximum, when the cobs are separated - the minimum, and then again the minimum gap when the upper part of the stem is pulled. In this way, the damage to the stem is reduced, and the leaf buds are reduced. 2 Il. ko OS SP with iCO 4 with

This invention relates to agricultural machinery and can be used in corn harvesters.

The purpose of the invention is to expand it. reliability of the process by reducing damage to the stem when pulling it in the gap between the plates.

FIG. 1 depicts a mast machine, general view, in axonometric view; in fig. 2 - the same section.

The ratchet apparatus consists of 1, two rotating towards each other pulling rollers 2, mounted above them by means of elastic elements 3 of movable strip plates 4, which have an axis of rotation 5. Plates 4 are installed 20 at an angle to each other, the top of which is directed upwards. The apparatus has stops 6, limiting the movement of the plates 4. The stops 6 are adjustable in height. The device also has a power supply .7 providing oscillations of the 4 in one phase.

The proposed apparatus operates as follows.

When the harvester moves along the row, the stalks are inserted into the machine between the rollers 2, the stripper plates 4 installed with a gap c (i, and pulled down. The ear, approaching the plate 4, rotates it. The elastic elements 3 contract and thus weaken The force of the stroke of the cob on the plate. The stops 6 limit the movement of the plate 4 at the moment when the gap between the plates 4 becomes equal to "2 (assuming a 7" 2) that moment the separation of the cob 25

its contact with plate 4 increases and the force of deformation acting on the cob, according to Hooke's law, decreases, which also helps to reduce damage to the cob. The drive provides simultaneous and equal rotation of the plates.

During the period of pulling the lower part of the stem, the gap between the plates 4 is maximal, while separating the cobs is minimal and then again the minimum while pulling the upper part of the stems. Thus, by installing the plates 4 at an angle to each other, the gap between them is automatically changed, which ensures reduction of damage to the stem, leaf brushing and clogging of the pile of leaf-sticking impurities.
