Abstract

The invention relates to the technical field of asphalt pavers, and discloses a road asphalt paver double-pump oil supply unloading loop abnormity processing device which comprises a valve body, a shell is arranged at the top of the valve body, and a dredging structure is arranged in the shell. And the dredging structure comprises a moving block, a threaded rod, a movable plate, a top plate, a spring, a protective shell, a threaded cylinder, a rotary knob, a dredging rod, a fixed block, an arc-shaped plate, a limiting plate and a connecting block. The movable plate translates to drive the dredging rod to be inserted into the damping hole to clean blockages, a user can control the movable plate to perform multiple actions such as translation, overturning and resetting only through rotation and effectively complete dredging of the damping hole, and the head of the dredging rod is conical and can quickly break through the blockages in the damping hole.

Description

technical field [0001] The invention relates to the technical field of asphalt paver, in particular to an abnormal treatment device for a double-pump oil supply and unloading circuit of a road asphalt paver. Background technique [0002] The asphalt paver is a machine that evenly spreads the asphalt mixture on the road base, and conducts preliminary vibrating and leveling. There are two types of crawler type and tire type. It consists of two parts: traction, paving, vibrating and ironing. The former includes frame, power unit, traveling device, hopper, material gate, scraper conveyor, screw spreader and cab, etc. Unloading valves are often used in asphalt pavers. Unloading valves refer to certain conditions. A valve that unloads the hydraulic pump. The unloading valve is usually a relief valve with a two-position two-way valve (usually a solenoid valve). Its function is to use it to set the main pressure of the system (oil pump) when it is not unloaded. Through valve act...
