Hydraulic tensioning device for rubber track tensioning wheel

Abstract

The invention discloses a hydraulic tensioning device for a rubber track tensioning wheel. The hydraulic tensioning device comprises an oil inlet pipe joint, a pressure gauge, a wall penetrating pipejoint, a three-way pipe joint, a high pressure oil pipe, a joint body, a tensioning cylinder and a nut. The hydraulic tensioning device is characterized in that the pressure gauge and the oil inlet pipe joint are installed on the outer side plate of a frame body upper frame, and the oil inlet pipe joint is connected with the tensioning cylinder and the pressure gauge through the wall penetrating pipe joint, the three-way pipe joint and a hydraulic hose. The tensioning cylinder is installed in the square tube of a frame body lower frame main beam, and the piston rod of the cylinder props against a tensioning bracket of the tensioning wheel, to realize tensioning of the tensioning bracket. The hydraulic tensioning device has the effects that the tensioning requirement of a triangular track wheel train walking system of a combine harvester can be met, a rubber track is ensured not to fall off during the transmission process, the impact, on the road surface, of a wheel train can be effectively reduced, dual functions of shock absorption and tensioning are fulfilled, the hydraulic tensioning device can automatically adapt to the tensioning amount, and manual adjustment is not needed.

Description

technical field [0001] The invention relates to the technical field of tensioning equipment, in particular to a hydraulic tensioning device for a rubber track tensioning wheel. Background technique [0002] The combine harvester is a machine that can complete the harvesting, threshing, separation and cleaning of grains at the same time, and finally obtain clean grains. It generally consists of a harvesting platform, a threshing system (including threshing, separation, and grain cleaning devices), conveying, rotating, and walking devices, grain compartments, and operating mechanisms. Using a combine harvester can greatly increase labor productivity and reduce labor intensity. According to the power configuration, it can be divided into traction type, self-propelled type and suspension type. [0003] At present, the hydraulic tensioning device used in the combine harvester on the market cannot meet people's needs. When the traditional hydraulic tensioning device is used, the...

Problems solved by technology

[0003] At present, the hydraulic tensioning device used in the combine harvester on the market cannot meet people's needs. When the traditional hydraulic tensioning device is used, the rubber track is easy to fall off during the transmission process, and it cannot effectively slow down the impact of the road on the wheel train. Shock, can not automatically adapt to the tension, need manual adjustment
