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.
