Description

Agricultural thresher device

Technical Field

The invention relates to the field of agricultural machinery, in particular to an agricultural thresher device.

Background

The thresher is a common agricultural mechanical device and generally comprises a machine shell and a roller which is arranged in the machine shell and is axially horizontal, when the thresher works, a straw is fed into the position of the roller in the machine shell, the roller is driven to rotate by a motor, and the rice on the straw is threshed by the rotating roller. The root of the straw needs to be held by a worker in the working process of the existing thresher, and the straw is pressed at the position of the roller, so that the roller is kept in contact with the straw. Some thrashers need not the staff handheld straw, directly put into the casing with the straw can, but there is the problem that can't keep the contact all the time between straw and the roller in its working process to the straw is mixed together with the unhulled rice easily after final thrashing.

The invention aims to provide an agricultural thresher device to solve the problems of the prior art.

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

an agricultural thresher device which characterized in that: the cylinder comprises a cylinder body which is vertical in the axial direction, the bottom of the cylinder body is closed, the top of the cylinder body is open and is provided with a cylinder opening, a lower support hydraulic cylinder which is vertical in the axial direction is eccentrically and fixedly arranged at the bottom of the cylinder body, a piston rod of the lower support hydraulic cylinder is vertically upwards and fixedly connected with a supporting seat, an axially vertical motor is fixedly arranged in the supporting seat, an output shaft of the motor vertically upwards penetrates out of the supporting seat, a supporting plate which is vertical in the axial direction is arranged in the cylinder body and is positioned above the supporting seat, the bottom center of the supporting plate is fixed at the shaft end of the output shaft of the motor, the top of the supporting plate is connected with a cylinder, the cylinder is coaxially sleeved with an upper pressure plate, the top of the cylinder is connected with an upper platform, an upper connecting plate is arranged at the, each connecting rod upwards passes fixed connection in the upper junction plate again after the upper mounting plate respectively, the barrel inner wall is equipped with the arc wall corresponding to under bracing pneumatic cylinder eccentric direction one side position, and a plurality of axial vertical rubber rollers are installed to the arc wall internal rotation, and every rubber roller all has one side to expose from the arc wall at place, and the barrel bottom is equipped with the discharge gate corresponding to the spatial position between under bracing pneumatic cylinder, each rubber roller.

The agricultural thresher device is characterized in that: the supporting seat top is equipped with the lower annular that encircles the center, and the supporting disk bottom corresponds lower annular position and is equipped with the annular, installs a plurality of balls between the upper and lower annular.

The agricultural thresher device is characterized in that: the center of the bottom in the cylinder body is connected with an outer sheath, and the outer sheath is coaxially sleeved outside the lower support hydraulic cylinder.

The agricultural thresher device is characterized in that: and a plurality of salient points are formed on the surface of each rubber roller respectively.

The agricultural thresher device is characterized in that: the outer diameter of the upper pressure plate is smaller than or equal to that of the support plate.

When the rice straw separating machine works, firstly, the supporting seat, the supporting disk and the parts above the supporting seat are integrally lifted to the position above the opening of the cylinder body through the lower supporting hydraulic cylinder, a worker places rice straws on the supporting disk and on the side opposite to the eccentric direction of the lower supporting hydraulic cylinder, the rice straws are integrally distributed in an arc direction, the roots of the rice straws are inward, the upper connecting plate and the upper pressing disk are driven to move downwards through the upper hydraulic cylinder after the rice straws are integrally placed, the roots of the rice straws are pressed on the supporting disk through the upper pressing disk, and the worker can release hands to separate from the machine. Then the lower support hydraulic cylinder drives the support seat, the support plate and the parts above the support seat to integrally move downwards, so that the rice straw clamped between the upper pressure plate and the support plate is positioned in the cylinder body, and then the motor drives the support plate to integrally rotate. The rotation in-process is because the lower support pneumatic cylinder is eccentric mounting in the barrel bottom, therefore the rice pole contacts gradually with the barrel inner wall when rotating, and when the rice pole rotated to lower support pneumatic cylinder eccentric direction one side, the rice pole received the rubber roller extrusion of barrel inner wall to keep in contact with the rubber roller, make the rice pole break away from at the rotation in-process corn through the bump on rubber roller surface.

According to the rice straw threshing machine, rice straws can be stacked on the supporting plate in multiple layers, so that threshing operation can be performed on a large number of rice straws at one time, the root parts of the rice straws are clamped by the supporting plate and the upper pressure plate in a matching mode in the threshing process, manual rice straw operation is not needed, threshing is realized by utilizing the contact of the rubber roller and the rotating rice straws, the rice straws are gradually extruded and bent when being in contact with the rubber roller in the rotating process, and therefore the rice straws can be kept in contact with the rubber roller all the time in the threshing process. The threshed straw is clamped between the supporting disk and the upper pressure disk and cannot be mixed with the rice.

Compared with the prior art, the threshing machine reduces the working intensity of threshing operation, can perform threshing operation on a large number of rice straws at one time, improves the working efficiency, and can completely separate the rice straws from the rice straws after threshing.

Detailed Description

The invention is further illustrated with reference to the following figures and examples.

As shown in fig. 1-3, the agricultural thresher device comprises an axially vertical cylinder body 1, the bottom of the cylinder body 1 is closed, the top of the cylinder body 1 is open and is provided with a cylinder opening, an axially vertical lower support hydraulic cylinder 2 is eccentrically fixed at the bottom of the cylinder body 1 rightwards, the center of the bottom in the cylinder body 1 is connected with an outer sheath 3, and the outer sheath 3 is coaxially sleeved outside the lower support hydraulic cylinder 2. The piston rod of lower supporting hydraulic cylinder 2 is vertical upwards and fixedly connected with supporting

seat

4, 4 internal fixations of supporting seat have the vertical motor 5 of axial, the vertical upwards of output shaft of motor 5 wears out from supporting seat 4, it is equipped with the vertical supporting disk 6 of axial to lie in 4 tops of supporting seat in the
