[0002] The hydraulic valve box of the trenching plow is located at the top platform of the trenching plow. The valve box body is installed vertically, the valve box shell is smooth, and the valve box material is alloy steel. At present, a pair of handles are welded on the valve box as gripping fulcrums to facilitate disassembly of the valve box.

[0003] However, because welding generates a large amount of heat, it can cause the alloy steel to deform, affecting the flatness of the valve box sealing end surface and potentially exacerbating oil leakage. Therefore, no welding or modification can be performed on the valve box itself. In addition, the valve box is surrounded by other equipment, which limits the position of personnel during the disassembly process. There is no protective grille at the bottom of the valve box, and the valve box end cover weighs approximately 40 kg, requiring manual handling during the disassembly process. For such a heavy shell, manual handling poses a risk of falling from a height.

[0007] Furthermore, a valve box is provided in the valve box end cover, and an oil drain port is provided on the valve box end cover to drain the compensating hydraulic oil leaked in the valve box.

[0008] Furthermore, the two slide rails are fixedly connected to one side of the main frame along the width direction of the main frame.

[0009] Furthermore, both ends of the support plate are respectively arranged on the slide rails so that the support plate slides along the length direction of the slide rails.

[0010] Furthermore, a first connecting plate is vertically connected to the support plate, and a second connecting plate is vertically connected to one end of the support plate away from the first connecting plate, so that the first connecting plate and the second connecting plate are arranged in parallel.

[0011] Furthermore, two ends of the third connecting plate are respectively vertically connected to the first connecting plate and the second connecting plate, so that the third connecting plate is parallel to the support plate.

[0012] Furthermore, a limit block is provided on the main frame to limit the sliding position of the support plate.
