This double speed rice huller has adopted belt drive, has adopted a rice huller motor, is a single motor drive's double speed rice huller, can effectively control the cost of double speed rice huller.
According to the double-speed rice huller, the speed of the movable rubber roll is switched through the action of a set of combined structure of a shifting cylinder, a shifting pull rod and a sliding claw, so that the rotating speed ratio between the movable rubber roll and the fixed rubber roll is switched, and the rice huller obtains different linear speed differences. However, there are the following problems:

2: the problems of rapid wear and heating failure of partial parts exist, and the related speed change structure has high failure rate. Specifically, the surface of a shaft part for mounting the belt pulley, namely a rubber roll shaft, needs to be grooved to provide a vacancy required by axial movement of a sliding claw, impurities such as dust and chaff easily enter the shaft from the vacancy, and a shift-shifting pull rod in the rubber roll shaft is easily affected by the impurities in the switching process to generate heat and lose efficacy, so that the fault rate of the whole related speed change structure is high, and the shift-shifting pull rod needs to be replaced regularly; in addition, the related speed change structure has a large number of parts, and not only are shift pull rods, sliding claws, belt wheels and mounting parts for mounting the belt wheels, such as bearings, connecting keys, bearing end covers and the like, arranged on the rubber roll shaft, but also parts such as air cylinders and the like are arranged on the outer side of the rubber roll shaft in the axial direction, so that the problems of complex structure, inconvenience in mounting, inconvenience in maintenance and the like are caused, and in addition, the shift pull rods are non-standard parts and need to be customized.
3: in the structure, the cylinder drives the shifting pull rod to act, so that a clutch part of the sliding claw in the rice huller can be connected and switched between the fast roller belt wheel and the slow roller belt wheel, and the speed of the movable rubber roller is switched; in addition, whether the sliding claw is connected with the fast roller belt wheel or the slow roller belt wheel, after the sliding claw is connected, the sliding claw must be kept at a fixed position through a retaining force provided by a driving part, namely a shifting cylinder, when the cylinder is weak or the retaining force is insufficient, not only is the connection between the sliding claw and the fast roller belt wheel or the slow roller belt wheel easily disconnected, but also the sliding claw is suddenly disconnected with the fast roller belt wheel and the slow roller belt wheel in the working process of the rice huller, so that the abrasion of the sliding claw, the fast roller belt wheel and the slow roller belt wheel is easily accelerated, and the service life of a related speed change mechanism is shortened.
