The working principle is as follows: when the mower is used, the driving machine 2 is started, so that the driving machine 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the mowing blade 4 to rotate for mowing, when the mowing blade 4 mows, due to inertia, the mowing blade 4 can beat grass on the inner wall of the mower main body 1, and the grass beating on the inner wall of the mower main body 1 falls onto the baffle ring 33;

when the rotating shaft 3 rotates, the rotating shaft 3 drives the first gear 35 to rotate, the rotating first gear 35 drives the second gear 37 and the third gear 38 to rotate, the rotating third gear 38 drives the fourth gear 40 to rotate, the rotating fourth gear 40 drives the rotating ring 32 to rotate, the rotating ring 32 drives the baffle ring 33 to rotate, the rotating baffle ring 33 drives the grass falling on the baffle ring 33 to move, and when the grass on the baffle ring 33 moves to a certain position, the grass on the baffle ring 33 slides into the collecting box 36;

when the dead angle which can not be harvested needs to be repaired, the electric push rod 22 can be started through the control switch 23, so that the electric push rod 22 pushes the second piston 21 to move, the moving second piston 21 compresses the air in the slide chamber 20, so that the air in the slide chamber 20 enters the slide hole 17 through the connecting hole 25, when the air pressure in the sliding hole 17 is increased, the air pressure presses the first piston 18, the moving first piston 18 pushes the first push rod 19, the push block 15 and the sleeve wheel 14 to move, the moving sleeve wheel 14 extrudes and pulls the transmission belt 13, so that the transmission belt 13 is tightly abutted to the first belt pulley 9 and the second belt pulley 11, the second belt pulley 11 can drive the first belt pulley 9 to rotate through the transmission belt 13, the rotating first belt pulley 9 drives the rotating rod 8 to rotate, the rotating rod 8 drives the grass cutting belt 10 to rotate, and the rotating grass cutting belt 10 repairs the grass at the dead angle;

after the grass at the dead angle is repaired, the control switch 23 controls the electric push rod 22 to reset, after the electric push rod 22 resets, the spring 29 pulls the slide block 28, the movable slide block 28 pulls the pull rod 30 and the pull wheel 31, and the movable pull wheel 31 pulls the transmission belt 13, so that the transmission belt 13 is separated from the contact with the second belt pulley 11, and therefore, when the device is normally used for mowing, the rotating second belt pulley 11 cannot contact the transmission belt 13, and the transmission belt 13 is prevented from being worn by the rotating second belt pulley 11;

it should be noted that if the air cannot push the pulley 14 to push and pull the driving belt 13, water can be injected into the sliding cavity 20, and due to the low compressibility of water, the water can move the first piston 18, the first push rod 19, the push block 15, and the pulley 14 by using water pressure when the electric push rod 22 pushes the second piston 21.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
