The invention provides a transmission belt pulley and a rubber roller rice huller speed change device with the same. The transmission belt pulley is defined by a plurality of fan-shaped belt pulley blocks. Each belt pulley block is provided with a circular arc end portion bonded to an external transmission shaft, an end tooth portion meshed with the external transmission shaft and a fan-shaped installation plate used for connecting the circular arc end portion and the end tooth portion. The transmission belt pulley is simple in structure and convenient to process. According to the rubber roller rice huller speed change device, a chuck is sleeved on the end portion of a rubber roller, the transmission belt pulley is arranged on the end face of the chuck in sliding mode, the belt pulley blocks of the transmission belt pulley can slide radially along the chuck, and the rubber roller rice huller speed change device with the transmission belt pulley is capable of achieving stepless speed change, speed change or change of linear speed of a quick roller and a slow roller, simple in speed change and convenient to adjust.
Description
technical field [0001] The invention relates to the field of agricultural processing machinery, in particular to a transmission pulley and a rubber roller huller transmission device with the transmission pulley. Background technique [0002] The rubber roller huller is the leading equipment in the complete set of rice processing equipment. Its main function is to hustle the rice and separate the rice husk from the rice husk. Its working principle is to use a pair of rubber rollers that rotate in opposite directions, with different rotational speeds and different linear speeds, so that the rice that enters between the two rubber rollers is peeled under the action of the difference in the linear speed of the rubber rollers and the applied pressure. The mixture of rice husk and chaff enters the chaff separation chamber, and the chaff in the mixture is separated after wind selection. At present, the commutation and speed change of the rice huller on the market mainly adopt the ...
