Abstract

The invention discloses a forced compression device of a low power roller tractor. The device comprises a lifter, a hydraulic oil cylinder is arranged in the lifter, the lifter is connected with a lifting rod, the lower end of the lifting rod is hinged to a lower link, the device further comprises an oil absorption filter, an oil absorption gear pump, an oil return filter, a floating multiway valve, a right oil cylinder and a left oil cylinder, one end of the oil absorption gear pump is connected to the hydraulic oil cylinder through the oil absorption filter, the other end of the oil absorption gear pump is connected with the inlet path of the floating multiway valve, the floating multiway valve is connected with the right oil cylinder and the left oil cylinder in sequence, the upper end of the right oil cylinder and the upper end of the left oil cylinder are both hinged to the lifting rod, a loop of the floating multiway valve is connected to the hydraulic oil cylinder through the oil return filter, a position control operation handle is further installed on the lifter, and the operation handle is connected with the floating multiway valve through a Q-shaped support. By means of the device, the problems that it is difficult for the low power roller tractor to break ground in hard soil, and the ploughing depth is shallow are solved.

Description

technical field [0001] The invention relates to a tractor auxiliary device; in particular, it relates to a low-power wheeled tractor pressure device. Background technique [0002] At present, most of the existing small and medium-power wheeled tractors in China can only realize the lifting of agricultural implements, and the lowering is passively lowered by the self-weight of agricultural implements. For hard soil, there are defects such as slow entry into the soil and shallow entry into the soil. [0003] After retrieving, do not find that existing tractor can have the device that makes agricultural implement be forced into the soil. Contents of the invention [0004] The purpose of the present invention is to provide a low-power wheeled tractor pressing device, which solves the problems of difficulty in entering the soil and shallow plowing depth of medium and small-power wheeled tractors in hard soil. [0005] In order to achieve the above object, the present inventio...
