Abstract

The invention discloses a pressing control device for a rolling brush of a snow sweeper and belongs to the technical field of engineering machinery. The device comprises a lifting cylinder and a hydraulic pump, wherein the lifting cylinder is used for driving the rolling brush to press down; the hydraulic pump is used for supplying pressure oil to the lifting cylinder; a solenoid directional valve is arranged between the lifting cylinder and the hydraulic pump; a sensor used for sensing the abrasion of the rolling brush is also arranged on the device; the sensor is connected with an electric control end of the solenoid directional valve through a controller; an automatic pressing switch for the rolling brush and a snow sweeping operation handle are arranged at a control end of the controller. The pressing control device is capable of solving the problem of easy abrasion of the rolling brush or incomplete snow sweeping caused by the difficulty in controlling the contact pressure between the rolling brush of the snow sweeper and the ground within the optimal scope.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery manufacturing, in particular to a rolling brush downward pressure control device for a snow removal vehicle. Background technique [0002] The rolling brush down pressure control device of the snow removal vehicle is a device that controls the rolling brush set on the snow removal vehicle to press against the ground, so that the rolling brush contacts the ground and generates a certain contact pressure to clean the snow on the road surface; figure 1 The shown snow removal vehicle rolling brush downward pressure control device includes a lifting oil cylinder 01 that drives the rolling brush downward and a hydraulic pump 02 that provides pressure oil for the lifting oil cylinder 01. One-way hydraulic pressure is sequentially arranged between the lifting oil cylinder 01 and the hydraulic pump 02. Lock 04 and solenoid reversing valve 03. The electric control end of solenoid reversing valve 03 ...
