Description

one

The invention relates to agricultural machinery and can be used in the construction of threshers for

corn.

The purpose of the invention is to simplify the design, increase productivity and complete threshing.

Figure 1 presents the scheme of the device for threshing cobs; Fig. 2 is a diagram of the drive of rotation of the rolls; Fig. 3-10 shows the arrangement of the mutual arrangement of the rolls after Q, their rotation for every 45 °; 11 to 18, the same embodiment.

The device has mounted on the shafts 1 and in pairs located the oblomichic capture system of the cob, its thresh and ejection of the rod (not shown).

A four-roll device provides threshing from one feed line (not shown). To expand the threshing front, the device can be made six or eight roll. Moreover, to improve threshing, the rolls 2 may have a textured surface in the form of grooves, shchipov, chevrons, etc.

The device works as follows.

The two upper rollers 2 are rotated so that their surfaces draw the cobs into the inter-roll space. The lower rolls 2 rotate in the directions indicated by the arrows, pairwise in opposite direction.

driven on each shaft 1 driven wheel-4 can interact

4 kinematic gears between all gears with a shift in rotation angle

Lamy 1 is made with a gear ratio, so that at the moment, for example,

equal to one. The rolls 2 are set to fully open the upper rolls 2 when

the distance between their cylindrical surfaces will be maximum, the lower rolls 2 will have a different distance between the surfaces, for example such as to prevent through-slipping of the cob CJlbnU. I DV. I - J and j (ivx 1-1-1,1-l V j -.- v- „.j -.

In this way, the direction of displacement of the axis of each 25 cut upper and lower pair of rolls. The bottom 2 of one pair can coincide with the pair of rolls 2 that rotate, not by shifting the axis of the roll 2 to another to engage and pick the cob, it

The pair is positioned one-way with the WTO-holds the cob and turns it.

In the process of cob interacting with the axles are located at an angle of 45 ° with each other, the upper surfaces of the rolls 2 are threshed to the barrel (see Figures 11-18) -. All elements of the mouth-grains. The threshing cycle of the cob is completed; the rotations are mounted on the frame 8. In the device, for one revolution of the rolls, after which the device can be provided for automatic readiness to begin the next cob
