Abstract
The utility model discloses a transmission belt reversing device, comprising a motor shaft, a first pulley installed on the motor shaft and a second pulley installed on the motor shaft. The utility model is characterized in that the left end in an axle hole of the first pulley is provided with a two-way bearing, and the right end in the axle hole of the first pulley is provided with a one-way bearing; the left end in an axle hole of the second pulley is provided with a one-way bearing, and the right end in the axle hole of the second pulley is provided with a two-way bearing. The transmission belt reversing device can be used on a rice grinding and crushing integrated machine, and a belt does not need to be replaced when a rice grinding machine and a crushing machine mutually convert work.
Description
Affiliated technical field
The utility model relates to a kind of drivign belt reversing arrangement, relates in particular to the drivign belt device on the rice milling and grinding machine.
Background technique
At present, a belt pulley only has been installed on the motor shaft in rice milling and grinding machine, when rice milling machine and the mutual conversion work of shredder, must have been changed belt, very trouble.
Summary of the invention
The utility model provides a kind of drivign belt reversing arrangement in order to address the above problem proposition, to its objective is, this drivign belt reversing arrangement does not need to change belt when shredder and the mutual conversion work of rice milling machine.
The technological scheme that adopts is: comprise motor shaft 1, be installed in first belt pulley 2 on the motor shaft 1, be installed in second belt pulley 3 on the motor shaft 1, it is characterized in that: the left end in the axis hole of first belt pulley 2 is installed a two-way bearing 4, right-hand member in the axis hole of first belt pulley 2 is installed a unilateral bearing 5, left end in the axis hole of second belt pulley 3 is installed the interior right-hand member of axis hole of 5, the second belt pulleys 3 of a unilateral bearing a two-way bearing 4 is installed.When motor just changeed, first belt pulley rotated, and second belt pulley stops operating.When motor reversed, second belt pulley rotated, and first belt pulley stops operating.Therefore, when rice milling machine and the mutual conversion work of shredder, do not need to change belt, realize auto reversive purpose.
The beneficial effects of the utility model are: when rice milling machine and the mutual conversion work of shredder, do not need to change belt.
