Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural engineering and can be used for crop threshing. A threshing device comprises loading screw units, beating chambers and unloading unit set on a drive shaft. Each beating chamber is formed by a drive threshing disc and a separating perforated disc. The threshing device is equipped with a separating unit mounted on the drive shaft and a fixed shear rake. The separating unit is made as a rotating faceplate with cutting peripheral sections and is set between the coupled threshing units and loading units with horizontal screws.

EFFECT: threshing device is of high productivity and process reliability.

Description

The invention relates to agricultural machinery.

A threshing device is known, consisting of two drive augers, a threshing chamber with main and additional disks, moreover, conical rollers are mounted in additional disks with the possibility of rotation around their axes (1).

A disadvantage of the known design is the excessive complexity of the design.

A threshing device (2) is known, including a loading and unloading device and a threshing chamber formed by two disks, one of which is mounted on a drive shaft.

A disadvantage of the known device is that it is intended for threshing only corn, and the threshing is accompanied by damage to the grain.

The closest in technical essence to the claimed device is a threshing device (3), selected as a prototype, including a loading screw device mounted on the drive shaft, an unloading device and a threshing chamber formed by two disks, one of which is drive, and the second is separating with perforated surface. The loading device is made in the form of a vertical screw mounted on the drive shaft.

The disadvantage of this device is the low bandwidth.

The technical task of the invention is to increase the technological reliability and throughput of the threshing device.

The task is achieved in that the threshing device comprising a loading screw device mounted on a drive shaft, an unloading device and a threshing chamber formed by two disks, one of which is a drive and the other separating with a perforated surface, according to the invention is equipped with a fixed opposing comb and mounted on the drive shaft, a separation device made in the form of a face plate rotating with a cutting segment on the periphery of the face plate mounted between the pair threshing devices and loading devices with screws mounted horizontally.

Comparison of the claimed device with the prototype shows that the introduction of a stationary opposing comb fixed on the frame of the loading device and mounted on the drive shaft of the separation device made in the form of rotating with cutting segments on the periphery of the face plate installed between paired threshing devices and loading devices with screws, is new mounted horizontally.

The use of the separation device will allow to separate the grain-straw mass into two streams, increasing almost twice the throughput of the threshing device.

Thus, the claimed device meets the criteria of the invention of "novelty."

The device meets the criterion of "inventive step", as a result is achieved that satisfies the existing need, attempts to obtain which to date have not been successful by specialists, namely: improving technological reliability and throughput.

The invention is “industrially applicable”, as it can be used in agriculture for threshing grain mass on combines and stationary threshers.

The invention is illustrated by drawings.

Figure 1 schematically shows a threshing device, a top view; figure 2 place "B" of figure 1; figure 3 is a view along aa of figure 2; figure 4 is a view along A ₁ -A _{1 of} figure 2.

The threshing device contains paired threshing devices 1 and 2, loading screw devices 3 mounted horizontally on the drive shaft 4, an unloading device 5 and threshing chambers 6 formed by two disks 7 and 8, one of which 7 is a drive, and the second is a separating 8, stationary the opposing comb 9 mounted on the frame 10, the separation device 11 mounted on the drive shaft 4, made in the form of rotating with cutting segments 12 on the periphery of the faceplate 13, mounted between paired threshers ln devices 1 and 2 and loading devices 3 with screws located horizontally.

The technological process proceeds as follows.

Cut bread mass with the help of reel 14 and screws 15 enters the loading screw devices 3 to the cutting segments 12 and the counter comb 9 and is divided by them into two streams, which are sent by the screws of the loading device 3 to the threshing chambers 1 and 2. The threshing products are brought out through the unloading fixture 5.

The implementation of the invention will increase almost twice the threshing of the grain mass.
