Problems solved by technology
[0002] At present, when the hydraulic lifting system of domestic large and medium-power tractors is carrying farm implements or carrying plow tools to turn in the field, it is necessary to move the control handle plate of the hydraulic multi-way valve to the lifting position and position it. After the oil cylinder is lifted to the highest position, the multi-way valve will not Return to the neutral position, which will cause power loss and unnecessary heating of the hydraulic system; at the same time, the driver must continue to operate the multi-way valve, which also brings a lot of inconvenience to the driver

Embodiment Construction
[0020] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0021] Such as figure 1 As shown, this embodiment provides a tractor multi-way valve with automatic jump function, including a valve body 100 , a jump check valve body 200 and a connecting block 300 .
[0022] Valve body 100, valve body 100 is provided with a valve body stem 110, the head of the valve body stem 110 is provided with a handle 120, the tail is fixedly connected with a positioning rod 130, and the middle part is provided with an oil inlet 140, which is controlled by operating the handle 120 The displacement of the valve body stem 110 drives the displacement of the positioning rod 130. When the valve body valve rod 110 moves into the valve body 100 until the positioning rod 130 is stuck, it can start to work. A...

The invention discloses a tractor multi-way valve with an automatic skipping function and belongs to the technical field of multi-way valves. The tractor multi-way valve comprises a valve body, a skipping one-way valve body and a connecting block. A valve body valve rod is arranged in the valve body. The head portion of the valve body valve rod is provided with a handle, the tail portion of the valve body valve rod is fixedly connected with a positioning rod, an oil inlet is formed in the middle portion of the valve body valve rod, and the oil inlet is connected with an oil outlet formed in the top of the valve body through an oil inlet channel. The skipping one-way valve body is arranged in the valve body and comprises a skipping valve rod, the head portion of the skipping valve rod is provided with a protrusion, the tail portion of the skipping valve rod is provided with a valve element, and the valve element can move along with the skipping valve rod so as to communicate with the oil inlet channel or cut off the oil inlet channel. A sliding groove is formed in one end of the connecting block, the protrusion can slide in the sliding groove, and the other end of the connecting block is fixedly connected with the head portion of the valve body valve rod. The tractor multi-way valve has an automatic skipping function, the multi-way valve does not need to be continuously operatedduring running of a driver, power losses are reduced, convenience is improved, meanwhile, the structure is simple, and the cost is saved.
