Background

The rotary cultivator is a cultivating machine for cultivating and harrowing, has the characteristics of strong soil crushing capability and flat ground surface after cultivation, can cut off stubbles buried below the ground surface, is convenient for the operation of a seeder, provides a good seedbed for later sowing, and is widely applied.

The differential mechanism is a mechanism which can enable left and right (or front and rear) driving wheels to rotate at different rotating speeds. Mainly comprises a left half shaft gear, a right half shaft gear, two planet gears and a gear carrier. The device has the function of enabling the left wheel and the right wheel to roll at different rotating speeds when the automobile turns or runs on an uneven road surface, namely ensuring that the two sides of the automobile drive the wheels to do pure rolling motion. The differential is provided for adjusting the difference in the rotational speeds of the left and right wheels. In four-wheel drive, all the wheels must be connected to drive four wheels, if the four wheels are mechanically connected, the vehicle cannot rotate at the same speed when the vehicle runs on a curve, and in order to make the curve running rotation speed of the vehicle substantially consistent, an intermediate differential is added to adjust the rotation speed difference between the front wheel and the rear wheel.

In addition, in order to ensure that the vehicle can run straight, the differential is provided with a differential lock, and the differential lock is used for improving the passing capacity of the vehicle on a bad road surface, namely when one drive axle of the vehicle idles, the differential can be quickly locked, so that the two drive axles become rigid connection.
