Speed feedback system of vehicle-mounted asphalt distribution equipment

Abstract

The invention discloses a speed feedback system of vehicle-mounted asphalt distribution equipment. The speed feedback system comprises a control system, a speed relay and an audible and visual alarm device, wherein an output end of the speed relay is connected with the audible and visual alarm device for guaranteeing normal work of the asphalt distribution equipment and a control system for controlling work of a pump A and a pump B respectively; an output end of the control system is simultaneously connected with the pump A and the pump B to control the working speeds of the pump A and the pump B; and the speed relay is also in line connection with a running speedometer of the asphalt distribution truck. According to the speed feedback system, the problems existing in the prior art are solved; by additionally arranging the speed feedback system on the vehicle-mounted asphalt distribution equipment, the discharge speed of the asphalt distribution equipment can be automatically and accurately controlled; the structure is simple; and the speed feedback system is suitable for being widely used on equipment in related industries.

Description

technical field [0001] The invention relates to the field of asphalt paving equipment for roads and bridges, and specifically designs a speed feedback system for vehicle-mounted asphalt spreading equipment. Background technique [0002] Asphalt distributor is a special equipment for road and bridge construction. There is a two-component high-performance asphalt on the market, which needs to be transported and mixed through double pipelines at the construction site, and then sprayed. The discharge speed of the pipeline cannot be accurately controlled, and the speed of the sprinkler needs to be well controlled during on-site construction. The operation is difficult and the degree of automation is low. Contents of the invention [0003] Purpose of the invention: In order to solve the above problems, the present invention provides a speed feedback system of a vehicle-mounted asphalt spreading equipment with a high degree of automation and simple control. [0004] Technical sc...
