[0028] Working principle:

[0029] When the cutting of the blocking zone for forest fire extinguishing is needed, the device is moved to the required working site, after the device is moved to the required working site, the external power supply of the second motor 201 is connected and started, the second motor 201 drives the worm 202 to rotate, the worm 202 drives the worm gear 203 to rotate (the worm 202 and the worm gear 203 have self-locking function, when the plate body 205 does not drive the column 207 to move, the column 207 is not easy to move under the influence of the outside world, thereby increasing the stability of the column 207), the worm gear 203 drives the threaded rod 204 to rotate, the threaded rod 204 drives the plate body 205 to move downward and in turn drives the column 207 to move downward, the column 207 contacts the soil in the forest during downward movement, and in turn the column 207 is inserted into the ground, after the column 207 moves to the limit distance, the second motor 201 is turned off, by the above-mentioned manner, the column 207 is inserted into the ground, the contact between the device and the ground is increased, and in turn the stability of the device is increased, on the inclined road, the stability of the device can also be increased according to the above-mentioned manner, and the column 207 can be reset by reversely rotating the second motor 201;

[0030] Then the blocking zone to be cut is placed in the frame body 8 on both sides, after the blocking zone is placed in the frame body 8, the two bolts 9 are screwed, the bolts 9 rotate on the frame body 8 and move downward, in turn the bolts 9 drive the cross blocks 10 to move downward through the bearings, the lower ends of the two cross blocks 10 contact the blocking zone and in turn fix it, after the blocking zone is fixed, the rotation of the two bolts 9 is stopped;

[0031] Then the external power supply of the first motor 6 is connected and started, the first motor 6 drives the cutting blade 7 to rotate, then the external power supply of the air cylinder 4 is connected and started, the output end of the air cylinder 4 is elongated and drives the box body 5 to move downward and in turn drives the cutting blade 7 to move downward, the cutting blade 7 contacts the blocking zone and in turn cuts the blocking zone, and the debris generated in the cutting of the blocking zone falls into the collecting box 304 for collection, preventing the debris from falling into the forest and causing environmental pollution, after the cutting of the blocking zone is completed, the air cylinder 4 is started to make its output end retract and drive the cutting blade 7 to move upward to reset, after the cutting blade 7 is reset, the air cylinder 4 and the first motor 6 are turned off, then the two bolts 9 are reversely rotated to cancel the fixation of the blocking zone, the workers manually take out the cut blocking zone to complete the cutting work of the blocking zone, then the subsequent forest fire extinguishing work can be carried out by using the cut blocking zone.

[0032] When the debris in the collecting box 304 needs to be collected, the connecting block 301 is moved downward, at this time, the first spring 303 is contracted, and the movement of the connecting block 301 is stopped after the connecting block 301 is separated from the collecting box 304, thereby canceling the limiting of the collecting box 304 in the frame 1, at this time, the second spring 306 rebounds to drive the vertical plate 305 to move rightward, the vertical plate 305 moves rightward to push the collecting box 304 to move, since the lower end of the collecting box 304 is relatively smooth, after the vertical plate 305 moves rightward to push the collecting box 304, the collecting box 304 slides in the frame 1 for a distance and then slides out of the frame 1, when the collecting box 304 contacts the anti-skid layer 13, the collecting box and the anti-skid layer 13 generate a large friction force to slow down the collecting box 304 and finally make the collecting box 304 stop sliding, then the collecting box 304 is taken out of the frame 1, after the collecting box is taken out of the frame 1, the connecting block 301 is loosened, the first spring 303 rebounds to reset the connecting block 301, then the collecting box 304 is cleaned, after the cleaning of the collecting box 304 is completed, the collecting box 304 is positioned in the frame 1 again according to the above manner, and the cleaning work of the collecting box 304 is completed.
