Description

Cylinder type threshing device

Technical Field

The invention relates to the field of agricultural machinery, in particular to a barrel type threshing device.

Background

The thresher generally comprises a machine shell and a roller which is arranged in the machine shell and is axially horizontal, a worker feeds a straw into the position of the roller in the machine shell downwards during working, the roller is driven to rotate by a motor, and the straw is threshed by the rotating roller. The existing thrasher is in the working process, paddy which is thrashed when the roller rotates is easy to fly upwards, and the space is reserved above the roller for the paddy to stretch into, so that devices such as a baffle plate and the like cannot be arranged to block the flying paddy, the upward flying paddy can fly to the periphery of the machine shell and is difficult to collect, and the problem of waste is caused.

The invention aims to provide a cylinder type threshing device for threshing, which solves the problem that rice flies upwards in a threshing machine in the prior art.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the utility model provides a threshing device is threshed to cylinder threshing which characterized in that: including grudging post, a threshing cylinder, threshing copper draws together inner tube, urceolus, and urceolus one end is sealed, the other end is the nozzle, and the urceolus rotates to be connected on the grudging post, and the blind end of urceolus is fixed with the motor, the coaxial rotation of inner tube is installed in the urceolus, and inner tube one end is sealed, the other end is the nozzle, and the nozzle and the urceolus nozzle direction of inner tube are the same, motor output shaft passes urceolus blind end and fixed connection in the inner tube blind end, and the inner wall of inner tube is equipped with multichannel recess, and every recess is on a parallel with the inner tube axial respectively, rotates respectively in every recess and installs the axial and is on a parallel with the axial rubber roller of inner tube, and every rubber roller is partly exposed from the place recess respectively, the nozzle coaxial coupling of urceolus has the flexible pipe, and the, the top of the cover is divided into the end of the sleeve opening, the top of the cover is provided with a central through hole, and an elastic rubber ring is coaxially fixed on the inner wall of the central through hole.

The cylinder type threshing device is characterized in that: the axial length of the inner cylinder is consistent with the axial length of the cylinder cavity in the outer cylinder, and the outer diameter of the inner cylinder is consistent with the diameter of the cylinder cavity in the outer cylinder.

The cylinder type threshing device is characterized in that: the outer wall ring sleeve of urceolus is fixed with the clamp, and the clamp bottom is connected with the connecting plate, and the connecting plate lower part is rotated through the horizontal pivot of axial and is installed in the grudging post.

The cylinder type threshing device is characterized in that: limiting plates are connected to two symmetrical sides of the vertical frame respectively and used for limiting rotation of the connecting plates.

The cylinder type threshing device is characterized in that: the surface of the rubber roller is fully distributed with rubber salient points.

When the rice thresher works, the collar clamp is rotated to enable the opening of the outer cylinder to be upward, a worker holds the root of the rice straw by hands, the rice straw is fed into the inner cylinder after passing through the elastic rubber ring, the inner cylinder is driven to rotate through the motor, the rice is separated by utilizing the contact between the rubber roller in the groove on the inner wall and the rice straw when the inner cylinder rotates, and the axial direction of the inner cylinder is not mutually vertical to the feeding direction of the rice straw, so that the threshed rice is difficult to have enough momentum to fly out of the inner cylinder, and finally the threshed rice falls into the inner cylinder.

According to the rice straw separating device, the opening of the outer barrel is connected with the elastic telescopic pipe, the cover is covered on the opening of the elastic telescopic pipe, after the cover can be taken down from the opening, the roots of the rice straws are fully plugged with the elastic rubber rings of the cover, then the cover is installed on the opening, the elastic telescopic pipe is adjusted by bending in all directions by workers during working, so that the rice straws extending into the inner barrel can be fully contacted with the rubber rollers in all directions, and meanwhile, the elastic rubber rings are in a closed state because the roots of the rice straws are fully plugged with the elastic rubber rings, so that even rice straws with large momentum fly upwards, the rice straws can be blocked at the elastic rubber rings, and finally the rice straws can still fall into the inner barrel.

In the invention, the adjusting clamp is rotated in one direction, so that the threshing cylinder is inclined upwards in the cylinder opening, and the limiting plate on one side of the vertical frame limits the rotation of the connecting plate. After the work is finished, the hoop rotates to the other direction until the opening of the threshing cylinder is vertically downward, the limiting plate on the other side of the vertical frame limits the rotation of the connecting plate, and then the cover cap is taken down, so that the rice collected in the inner cylinder can be poured out.

Compared with the prior art, the rice threshing machine has the advantages that a large amount of rice cannot fly out in the working process, a blocking effect can be realized on a small amount of flying-out rice, the rice collecting efficiency after threshing and threshing is improved, the rice in the inner barrel can be poured out conveniently, and the rice threshing machine is convenient to use.
