[0063] In summary, the working principle of the present invention is as follows: when the trenching equipment is used, the device is first moved to the desired position, and the multi-stage hydraulic rod 5 is started through an external controller (the controller is not drawn in the figure). The operation of the multi-stage hydraulic rod 5 can move the sliding plate 6 downward, thereby adjusting the distance between the coulter 75 and the ground, and the depth of the trenching can be adjusted. When the distance between the coulters 75 needs to be adjusted, the handle 714 can be pulled outward, and the plug 713 can be moved away from the inner cavity of the adjacent slot 715 under the connection of the pull rod 712. Then the movable plate 71 can be slid upward. By means of the inclined slot 761 provided on the movable plate 71, the adjacent mounting seats 74 can slide under the limit of the adjacent guide rails B741 and the adjacent guide blocks B742 under the connection of the guide rods 76, so that the distance between the adjacent plow blades 75 can be adjusted. After adjusting to the appropriate position, the handle 714 is released and the elastic force of the resetting telescopic rod 7141 and the resetting spring 7142 can make the plug 713 stably inserted into the inner cavity of the slot 715. After the ditching work is completed, the pump body 12 can be started by the external controller to pump the water in the inner cavity of the water tank 11 into the spraying machine. The inner cavity of the tube 15 is sprayed out through the guide tube 16 to clean the mud adhering to the plow blade 75. After the cleaning is completed, the pump body 12 can be turned off by the controller. Then, the distance between the plow blades 75 can be adjusted by the multi-stage hydraulic rod 5. After the appropriate position is adjusted, the fixed motor 82 can be started by the controller. The rotation of the power output shaft of the fixed motor 82 drives the reciprocating screw 83 fixed to the shaft end of the power output shaft of the fixed motor 82 to rotate. The screw nut 84 movably sleeved on the outer periphery of the reciprocating screw 83 can reciprocate back and forth under the limit of the limit block 841 and the limit rod 842. The moisture on the periphery of the plow blade 75 can be wiped off by the wiping roller 86 located at the bottom of the cleaning plate 85. When the cleaning plate 85 moves toward the rear side, the tooth roller 863 engaged with it can be rotated with the cooperation of the rack plate 864. The wiping roller 86 can be rotated by the support rod 861 fixed on the tooth roller 863, thereby improving the wiping effect on the plow blade 75. When the screw nut 84 moves back and forth, the gas can be filled into the inner cavity of the cleaning plate 85 and sprayed out by squeezing or stretching the capsule 854, thereby drying the wiping roller 86 and improving the wiping effect on the plow blade 75.
