UA90157U - Garbage truck - Google Patents

Abstract

A garbage truck comprises a base vehicle, a hopper with rear receptacle mounted on the base vehicle, inside which there is placed a loading mechanism of garbage into the hopper, a hydraulic system and an electronic control unit, the hopper is equipped with a stripper plate mounted inside the hopper with possibility of reciprocating movement by means of a hydraulic cylinder, a mechanism of loading garbage into the hopper is made in the form of a bearing plate mounted with possibility of reciprocating movement up and down by means of hydraulic cylinders, and a pressure plate attached to the lower end of the bearing plate with possibility of rotation back and forth using hydraulic cylinders, the hydraulic system comprises a source of hydraulic pressure and hydraulic valves connected by a line with electromagnetic actuators of control valves of hydraulic cylinders of bearing and pressure plates, the electronic control device comprises a control unit, a hydraulic pressure sensor built in line and adjusted for actuation pressure, an upper position sensor of a bearing plate and a programmable microprocessor built in the control unit, wherein the sensor of hydraulic pressure in the line and upper position sensor of the bearing plate are connected to the inlets of the control unit, to the outlets of control unit are connected the electromagnets of valve actuators of hydraulic cylinders of the bearing and pressure plates, and a programmable microprocessor contains information on the procedure of actuation of said electromagnets. The electronic control unit further comprises a lower position sensor of the bearing plate connected to the inlet of the control unit, the bearing plate is made to stop the downward movement in case of actuation of the pressure sensor in the line and failure of the lower position sensor of the bearing plate and further motion up for a set value from the respective activated electromagnet, wherein the programmable microprocessor contains information on the time parameter of activated state of the electromagnet, whose value is proportional to motion up of the bearing plate, and the pressure plate is made with possibility of stop of forward rotation in case of actuation of the pressure sensor in the line and further rotation back from the respective activated electromagnet.
