Corn and rice thresher roller

technical field

The utility model relates to a part of a grain crop thresher, in particular to a corn and rice thresher roller.

Background technique

The corn thresher is used to remove the corn kernels on the peeled corn. The corn thresher has a frame. The core part of the corn thresher is the corn thresher roller positioned horizontally on the frame. The corn thresher roller has a cylindrical roller, and the cylindrical roller has an axis and a cylinder. The axes of the cylindrical rollers are on the same straight line as the main shaft of the threshing machine. The main shaft of the threshing machine is evenly distributed with radial spikes on the circumference of the cylindrical roller. The lower half cylinder of the cylindrical roller has sieve holes. There is a side feed port at the front end of the cylindrical roller, and a side discharge port at the rear end of the cylindrical roller. There is a shield around the corn threshing roller. There is a vibrating screen under the corn thresher roller. After the vibrating screen There is a grass exhaust fan above the end of the vibrating screen, and there is a grain outlet below the rear end of the vibrating screen. During the threshing operation of the corn thresher, the main shaft of the thresher is driven by the power machine to rotate, and the corn bucket is loaded into the cylindrical roller from the feeding port of the cylindrical roller, and the corn bucket entering the cylindrical roller is nailed by the nail on the main shaft. The teeth drive the rotation and move forward. During the movement, the corn is squeezed and rubbed in the cylindrical roller to remove the corn kernels from the corn cob, and the detached corn kernels are released from the lower half of the cylindrical roller. The sieve hole is sieved out, and after being sieved by the vibrating sieve, the broken grass is sucked out by the grass discharge fan, the corn kernels flow out from the grain outlet, and the corn cobs after the corn kernels are removed are discharged from the outlet of the cylindrical roller. This corn thresher roller can only be used for corn thresher.

The rice thresher is used to remove the rice grains from the cut rice grains. The feeding rice thresher has a frame. The core component of the rice thresher is the rice thresher roller placed horizontally on the frame. The rice thresher roller has two parallel cylindrical rollers, the upper and the lower. The cylindrical roller has a roller shaft whose axis is on the same line as the axis of the cylindrical roller, and the outer wall of the cylindrical roller is uniformly distributed with racks along the circumference, and radial bow teeth are evenly distributed on the racks. There is a fence around the drum of the rice thresher, there is a vibrating screen under the drum of the rice thresher, there is a rice feeding platform at one end of the drum of the rice thresher, and there is a straw discharge port at the other end of the drum of the rice thresher. 1. There is a horizontal rice clamping and conveying device between the lower two parallel cylindrical rollers, there is a grass discharge fan above the rear end of the vibrating screen, and there is a grain outlet below the rear end of the vibrating screen. This rice thresher roller can only be used for rice threshing; the rice grain clamping and conveying device is horizontal, and when threshing, the detached rice grains will fall on the horizontal rice grain layer and be discharged with the straw, so that the entrainment of the thresher High rate. In the prior art, there is no corn and rice thresher roller that can be used for both corn threshing and rice threshing.
