The rear end of the front and rear adjustment plate 9 protrudes from the roller fixing frame 7 and is provided with a folded edge 11 bent downward by 90°. The folded edge 11 is threadedly connected with an adjusting bolt 12 for adjusting the front and rear position of the front and rear adjustment plate 9. The front end of the adjusting bolt 12 is rotatably connected to the roller fixing frame 7 (specifically, it can be, but is not limited to, a bearing rotation connection).

[0031] As a further improvement of this embodiment, in order to control the adjustment accuracy, scales 25 arranged along the front and rear directions are provided on the roller fixing frames 7 on both sides of the front and rear adjustment plates 9, and pointers 26 cooperating with the scales 25 are provided at the center positions of both ends of the front and rear adjustment plates 9.

[0032] Side support plates 13 are fixedly installed on the front and rear adjustment plates 9, and a handle 14 is connected between the rear ends of the side support plates 13 on both sides. The front end of the side support plate 13 protrudes forward from the roller fixing frame 7 to form a protrusion 31, and the protrusion 31 also protrudes forward from the track 1, and a horizontal counterweight 32 is connected between the rear bottom ends. An electric cutter 15 is arranged between the front sides of the protrusion 31. The electric cutter 15 is installed between the protrusions 31 so that the angle can be adjusted forward and backward through the motor mounting plate 16. The electric cutter 15 is installed on the motor mounting plate 16 with adjustable cutting height. The output shaft of the electric cutter 15 is vertically forward and extends out of the motor mounting plate 16.

[0035] To further improve stability, a third arcuate groove 33 matching the rotation trajectory of the electric cutter 15 is provided on the other side of the lower portion of the connecting plate 34. The third arcuate groove 33 on the connecting plate 26 is connected to the motor mounting plate 16 by bolts.

[0036] To prevent the electric cutter 15 from interfering with the motor mounting plate 16 during its rotation around the rotation center, the hole on the motor mounting plate 16 for passing through the output shaft end of the electric cutter 15 is adapted to the running trajectory of the output shaft end during rotation.

[0037] During use of the present invention, the first handle bolt 18 is loosened and the motor mounting plate 16 is rotated to adjust the cutting angle of the electric cutter 15 . After the adjustment is completed, the first handle bolt 18 is tightened.

[0038] Loosen the second handle bolt 29 and the bolt between the third arc groove 33 of the connecting plate 26 and the motor mounting plate 16, and rotate the electric cutter 15 around the rotation connection point with the motor mounting plate 16 to adjust the cutting blade height of the electric cutter 15, thereby adjusting the cutting depth. After the adjustment is completed, tighten the second handle bolt 29 and the bolt between the third arc groove 33 of the connecting plate 26 and the motor mounting plate 16.

[0039] The cutting position of the electric cutter 15 in the front-to-back direction can be adjusted by loosening the bolts between the front-to-back adjustment plates 9 and the roller fixing frame 7 and rotating the adjustment bolts 12 .
