The rice thresher machine uses a 3 kW motor and a blower. The steering and stopping of the motor and fan are controlled by a reverse switch. The motor rotates clockwise to feed the rice spikes, the counterclockwise turn is mainly used to push out the rice spikes and troubleshoot, and the fan is used to blow off the chips and slag generated in the threshing. The motor passes the pulley, the continuously variable transmission pulley and the synchronous toothed belt pulley, so that the cutter head and the special-shaped cutter rotate the rice ear, and the steering handle is adjusted during operation to increase or decrease the cutter speed; the other transmission line is composed of two levels of triangle. The pulley and the worm gear drive the three groups of rollers to rotate.

The rice thresher machine drum is equipped with a compression spring, a rubber roller and a plastic roller. When the two rubber rollers rotate, the rubber roller functions as both a clamping and a rice ear. The spring can also adjust the two rollers according to the diameter of the rice. The distance between them is adapted to the requirements of different rice threshing. A set of plastic rollers holds and transports the rice to the waste bin. The tool and the cutterhead are lubricated with a drip cup and the oil is made from olive oil. In order to make the structure compact, the cutter head is equipped with plastic bearings. The plastic bearing rotates on the shaft.

The main lubrication part of rice thresher machine is worm gear, worm and plastic bearing. The worm gear and worm are open drive and lubricated with butter. The plastic bearing needs lubrication during operation. The standard needle valve type oil cup is used. The volume is 200 ml. And equipped with a drip-type tubing for this purpose, one end of the tubing is bolted to the oil cup, and the other end is connected to the oil groove on the bearing. During work, the size of the drip in the oil cup tubing can be adjusted. It is best to use olive oil for the lubricating oil, and the price can be tested with other edible oils.
