POST-CLEANING MACHINE OF A BREAD-BREEDING COMBINE, comprising rolls forming a bed, characterized in that, in order to increase productivity, it is equipped with a cob removal mechanism, having a bed profile and fixed between endless contours, which have profiles that are attached to endless contours. both sides. 2. An apparatus according to claim 1, characterized in that each scraper is provided with a toothed cutting element, wherein the number of its teeth is equal to the number of rollers.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, devices for treating cobs.

A corn cleaner of a corn combine harvester is known, comprising a device for preventing cob hanging, transporting the working bodies 1.

Also known as a pick-cleaning machine for a corn-harvesting combine harvester, including rollers forming the bed 2.

A disadvantage of the known corn cleaning machines of corn combines is the low productivity in processing the selection material for maize, since the operations for cleaning the apparatus from plant materials are carried out manually with the engine not running.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the corn-cleaning machine of the corn-harvesting combine harvester is equipped with a mechanism for removing cobs from the rollers, made in the form of scrapers having a bed profile and fixed between endless contours located along the rollers on both sides.

In addition, each scraper is equipped with a toothed cutting element, while the number of its teeth is equal to the number of rollers.

FIG. 1 shows the proposed pick-up apparatus, axonometrics; in fig. 2 — a mechanism for removing cobs from rollers, axonometrics; in fig. 3 — scraper of the mechanism for removing cobs from rollers with a toothed cutting element; in fig. 4 — node I in FIG. 3 (a scraper with a gear cutting element).

The apparatus comprises rollers 1 forming bed 2, and a mechanism 3 for removing cobs from rollers 1, including scrapers 4 having a bed profile 2, and fixed between endless contours 5 supported by drive elements 6 and located along rollers 1 on both sides. The infinite circuits 5 can be made in the form of chain or V-belt transmissions, and the drive elements 6, respectively, in the form of sprockets or shchivs. The scrapers 4 are fastened to the endless contours 5 with the help of the rail 7. The gear cutting elements 9 having teeth 10 are attached to the scrapers 4 by means of bolting 8. The gaps between the teeth 10 of the gear cutting elements 9 and the rollers 1 are adjusted due to the ovality of the holes 11 in the cutting elements 9 and by changing the position of the extreme rollers 1 forming the bed 2. Above the beds

2 rollers 1 are located the beaters 12 of the pressing mechanism 13, and the mechanism 3 for removing the cobs from the rollers G has an actuator 14 with a cam-type coupling 15. The device works as follows.

When using a corn scrubber in a corn-harvesting combine harvester, the latter, reaping the harvest of experienced cases, serves portions of the cobs to the rollers 1. The corncobs, the passage through the rollers 1, are cleared of wrapping leaves. The bitters 12 of the thrust mechanism 13 contribute to a more stable flow of the process of cleaning the ears from the wraps. The wrapping leaves are drawn into the gaps between the rollers 1 and further removed from the apparatus, and the cleaned cobs are removed from the rollers 1 and then packed up in a shed. Mechanism 3 removing cobs from rollers

0 1 can be used in continuous and batch modes. In the continuous mode, the clutch 15 of turning on the mechanism 3 is constantly on. The scrapers 4 constantly move in the beds 2 of the rollers 1 at a speed equal to the average speed of the flow of the cobs moving along the rollers 1. In the process of moving the scrapers 4 capture and move the retreating cobs to the gathering of the rollers 1. In this case, there is no need

0 in the inspection of the scrubber after harvesting from each experimental case. In the periodic mode of operation, the clutch 15 for switching on the mechanism 3 is activated only during the stops of the combine to the inter-night track after

when inspecting the apparatus in boxes 2, bedding cobs were found. After their removal, the mechanism 3 is turned off, while the scrapers 4 are stopped in such a position so as not to displace the movement of the cobs in the boxes

0 2 rollers 1.

If, during harvesting, a wound vegetative mass is found on rollers 1, the combine stops, the rollers 1 turn off, the clutch 15 is turned on. The gear cutting elements 9, the passage in the boxes together with the scrapers 4, cut the mass wound on the rollers 1 with their teeth. Then, the mechanism 3 is turned off and the rollers are rolled up to remove this mass.

0 The picker can be used as a stationary brush when threshing corn selection material, while its operation proceeds as described.

The use of the invention provides an increase in labor productivity, while reducing the labor intensity of servicing the scrubber during operation.
