Problems solved by technology

[0002] At present, loaders, skid steer loaders, backhoe loaders and other engineering machinery at home and abroad are equipped with a variety of tools to meet different working conditions; among them, snow blowers are one of the more common tools, mostly used in cold regions Snow removal equipment in winter, but currently the snow blower is generally controlled by a common valve block. When working, part of the pump flow is used for the work of the snow blower, and the excess flow flows back to the oil tank through the overflow valve, which cannot be controlled by the flow required by the snow blower. Set the flow rate, the efficiency loss is large, and the hydraulic shock is large

Abstract

The invention discloses a hydraulic system capable of throwing snow, and belongs to the technical field of engineering machinery. The hydraulic system comprises a snow throwing assembly, a hydraulic pump, a multi-way valve, an operation assembly, a control assembly and a hydraulic oil tank, the hydraulic oil tank is connected with the multi-way valve, the multi-way valve is connected with the operation assembly, the multi-way valve is connected with the snow throwing assembly through the control assembly, and the snow throwing assembly comprises an auger motor, a fan motor, an angle adjustingoil cylinder and a steering motor, the hydraulic pump is connected with the control assembly through the multi-way valve, the multi-way valve is connected with the operation assembly, the multi-way valve is connected with the hydraulic oil tank, and the auger motor, the fan motor, the angle adjusting oil cylinder and the steering motor are all connected with the control assembly. According to thehydraulic system capable of throwing snow, the snow throwing operation is controlled by arranging an independent snow throwing control assembly, the snow throwing operation is conducted according to needs, the loss of hydraulic efficiency is reduced, and impact on the hydraulic system is avoided.

Description

technical field [0001] The invention relates to a hydraulic system capable of throwing snow, belonging to the technical field of engineering machinery. Background technique [0002] At present, loaders, skid steer loaders, backhoe loaders and other engineering machinery at home and abroad are equipped with a variety of tools to meet different working conditions; among them, snow blowers are one of the more common tools, mostly used in cold regions Snow removal equipment in winter, but currently the snow blower is generally controlled by a common valve block. When working, part of the pump flow is used for the work of the snow blower, and the excess flow flows back to the oil tank through the overflow valve, which cannot be controlled by the flow required by the snow blower. If the flow rate is set, the efficiency loss is large, and the hydraulic shock is large. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the p...
