[0029] At the same time, in order to better exert the ditching ability of the ditcher, specifically, a hydraulic motor 3 is provided on the ditcher main body 29. The hydraulic motor 3 is welded to the tail end of the ditcher main body 29 through a mounting member. The mounting plate 16 is threadedly connected to the mounting member at the bottom of the hydraulic motor 3. The milling head 2 is rotatably connected to the rotating end of the hydraulic motor 3.

[0030] Furthermore, in order to enable the ditcher to travel normally in the non-working state, specifically, the ditcher main body 29 is provided with a hydraulic cylinder 4. One end of the hydraulic cylinder 4 is arranged at the upper end of the tail of the ditcher main body 29, and the other end of the hydraulic cylinder 4 is welded to the top end of the milling head 2. The hydraulic cylinder 4 retracts and extends the piston rod at the other end to lift and retract the milling head 2. At the same time, the soil discharging device 1 installed on the milling head 2 can be retracted, so that the ditcher can travel normally during the non-working stage.

[0031] Furthermore, in order to better control the operation of the ditcher, specifically, a power unit 5 is arranged at the inner side end of the ditcher main body 29, an air-cooled diesel engine 6 is arranged in the middle section of the ditcher main body 29, and a hydraulic piston pump 12 is arranged at the front part of the upper side wall of the ditcher main body 29. The air-cooled diesel engine 6 can be controlled by the signal of the remote control. The air-cooled diesel engine 6 drives the hydraulic piston pump 12 through a synchronous belt to provide power for the hydraulic motor 3, so that the hydraulic motor 3 drives the milling head 2 to rotate. The power unit 5 can be controlled by the signal of the remote control, and the power unit 5 can control the extension and retraction of the hydraulic cylinder 4.

[0032] It should be noted that, in order to control the normal walking and turning of the ditcher, specifically, a reduction motor 14 is arranged at the inner tail end of the ditcher main body 29, and a generator 15 is arranged at the inner side end of the ditcher main body 29. The generator 15 generates electricity to supply the reduction motor 14. The reduction motor 14 can be controlled by the signal of the remote control. After deceleration, the reduction motor 14 controls the rotation of the driving wheel a 23 and the driving wheel b 24. The driving wheel a 23 and the driving wheel b 24 drive the crawler 27 to rotate, so that the vehicle can move forward. There are two reduction motors 14, which can respectively control the rotation speed and rotation direction of the driving wheel a 23 and the driving wheel b 24 to realize the turning and backward movement of the ditcher.

[0033] Finally, to better utilize the performance of the trencher, specifically, a hydraulic oil tank 7 is provided on the inner sidewall of the trencher main body 29.

[0034] Combined Figures 1 - 8 , the specific use process of a tracked electric range-extended remote-controlled trencher in this embodiment is as follows: 1: According to the actual usage situation, start the air-cooled diesel engine 6 to run through the remote control. The air-cooled diesel engine 6 drives the hydraulic piston pump 12 to work through the synchronous belt, driving the hydraulic piston pump 12 to provide power for the hydraulic motor 3. After the hydraulic motor 3 starts, it drives the milling head 2 installed at the rotating end of the hydraulic motor 3 to rotate; 2. Start the power unit 5 through the remote control to control the operation of the hydraulic cylinder 4. The hydraulic rod at the other end of the hydraulic cylinder 4 extends, causing the position of the milling head 2 provided at the other end of the cylinder to change, driving the milling head 2 to descend until it contacts the ground in the area where trenching is required, and start the trenching work; 3. When the milling head 2 is trenching, as the trencher moves, the soil scattered by the milling head 2 in the trench will move along the guide plate 22 and finally be dispersed to both sides of the trench through the diverter plate 20, and there will be no problem of soil backfilling. To ensure the normal progress of the trenching work, the cross-sectional dimension of the milling head 2 and the distance between the two limit plates 21 both meet the required trenching dimensions; 4. When the air-cooled diesel engine 6 drives the hydraulic piston pump 12 to work through the synchronous belt, the rear end of the hydraulic piston pump 12 drives the generator 15 to generate electricity through the V-belt, and the electricity generated by the generator 15 is supplied to the battery pack of the reduction motor 14; 5. Start the two reduction motors 14 through the remote control. The reduction motors 14 drive the crawler 27 to rotate through the driving wheel a 23 and the driving wheel b 24, completing the walking action. The movement of the trencher can be controlled by controlling the driving wheel a 23 and the driving wheel b 24 by the reduction motors 14. The crawler teeth 28 welded on the crawler 27 contact the soil, and through the wavy structure of the crawler teeth 28, the ground can be better grasped, enabling the trencher to overcome structures such as low slopes and ridges in the working area and better adapt to working in environments such as farmland; 6. After the trenching work is completed, the power unit 5 controls the two hydraulic cylinders 4 to retract the piston rods of the hydraulic cylinders 4, changing the position of the milling head 2 provided at the other end of the cylinder, thereby driving the milling head 2 to rise and leave the ground, ending the work.
