Tractor distributor with balancing guide rod

Abstract

The invention discloses a tractor distributor with a balancing guide rod. The tractor distributor comprises a valve body, a front cover and a back cover. The valve body is internally provided with a valve rod, the first end of the valve rod extends into the back cover, and the second end of the valve rod extends into the front cover. The front cover is provided with a handle, one end of the handle extends into the front cover and is connected with the valve rod in a clamped mode so that the handle can be pulled to pull the valve rod to do linear movement in the axial direction of the valve rod, and the other end of the handle extends out of the front cover so that manual pulling can be facilitated. The end face of the end, far away from the valve body, of the back cover is provided with a through hole penetrating through the back cover, and the balancing guide rod is arranged in the through hole. The balancing guide rod can do linear movement in the through hole in the axial direction of the valve rod. The tractor distributor with the balancing guide rod has the advantages that the valve rod can automatically change the direction at back pressure, and the working reliability of the distributor can be improved.

Description

technical field [0001] The invention relates to a distributor, in particular to a distributor for a tractor provided with a balance guide rod. Background technique [0002] Hydraulic components have the advantages of high power, simple installation and arrangement, easy control, convenient and comfortable operation, low failure rate, and easy maintenance. They are very suitable for the application of agricultural machinery with variable structures and harsh working conditions. For decades, hydraulic technology has not only been used more and more in agricultural machinery, machine tools, engineering machinery, construction machinery, aerospace equipment, etc., but also formed a huge market. [0003] my country's agricultural machinery uses hydraulic components, with the largest number, the least variety, and the lowest price, so it is the industry with the most potential for development. One of the important factors is that the application of hydraulic technology in agricul...
