The working flow is as follows:

when the weed cutting device is used, firstly, the movable carrier 1 moves on the ground with weeds, the second driving structure 4 drives the main rotating shaft 23 to rotate, and the main rotating shaft 23 enables the plurality of cutters 22 to rotate around the axis of the main rotating shaft 23 through the two rotating discs 21, so that the weeds are cut.

Due to the structure consisting of the two rotating discs 21 and the plurality of cutters 22, a plurality of cutting positions exist in weeds, because the cutters 22 rotate around the axis of the main rotating shaft 23, each position is in a moving state, the moving carrier 1 moves on the ground with weeds, the upper ends of the weeds are firstly cut, then the lower ends of the weeds are cut, and among the plurality of cutters 22, the cutters 22 positioned at the lowest position are finally contacted with the weeds, so that the same weed can be cut for a plurality of times, and only a part of the weed is cut each time, thereby better ensuring that the weeds are cut better.

When mowing the lawn, the driving screw 463 can be driven by the driving motor to rotate, and the driving screw 463 makes the driving nut 464 drive the first driving rod 44 to move downwards or upwards through the driving nut 464, the guide rod 465 and the guide plate 466, so that the first driving rod 44 moves downwards or upwards to cause the second driving rod 45 to move upwards or downwards. The first driving rod 44 moves down to drive the connecting plate 43 to move down, and at this time, the second driving rod 45 moves up to move up the pivot at the transmission rod 42, so that the rectangular ring plate 411 moves up according to the lever principle, and the rectangular ring plate 411 drives the mounting block 413 to move up, so that one end of the main rotating shaft 23 moves up. When the drive motor drives the drive screw 463 to rotate reversely, one end of the main rotation shaft 23 can be moved down. Because the driving parts are provided with two groups, one end of the two ends of the main rotating shaft 23 can ascend and the other end of the two ends of the main rotating shaft are descended, so that the main rotating shaft 23 is inclined to the ground, and at the moment, when mowing, the lawn can be cut into a shape that the lawn surface is an inclined plane. In the running process, one end of the main rotating shaft 23 can be lifted and the other end can be lifted, or one end of the main rotating shaft is lifted and the other end of the main rotating shaft is lifted, and the switching is performed in a circulating and reciprocating mode, so that the lawn can be cut into a shape with a plurality of inclined planes staggered.

When in use, the two ends of the main rotating shaft 23 can be lifted and lowered simultaneously, so that the height of the cut lawn surface is controlled.

When using, first air pump 7 is through inside intercommunication of first connecting pipe 6 and main pivot 23, then blow in main pivot 23's inside with the air, the air can blow out from the through-hole again to can blow on cutting knife 22, when cutting knife 22 cuts the lawn, there is some grass adhesion on cutting knife 22, if not in time clear up, can influence the sharpness that cutting knife 22 mowed the lawn, the through-hole department outwards bloies to blow on cutting knife 22, blow away the grass on the cutting knife 22, thereby better assurance mowing effect.

The second air pump 51 sucks air from the upper side of the cutter 22 through the second connecting pipe 52 and the third connecting pipe 53, so that after the air and the cutter 22 cut the lawn, the grass blown by the wind at the through hole on the cutter 22 is sucked away and sucked into the storage chamber, even if the grass cut off is cleaned, the problem that the grass cut off is left on the cut lawn and needs to be cleaned for the second time is solved, and therefore the efficiency is greatly improved and the working time is saved.

When the lawn mower is used, the rotating motor 8 drives the driving shaft 81 to rotate, the driving shaft 81 sequentially drives the third connecting rod 84 to move through the first connecting rod 82 and the second connecting rod 83, the third connecting rod 84 swings back and forth around the supporting shaft 85 through the supporting shaft 85, so that the cleaning brush swings back and forth, the cleaning brush moves to the other end of the movable carrier 1 at one end of the movable carrier 1, grass which is not sucked by the second air pump 51 can be cleaned, grass which falls on a cut lawn can be gathered at the two ends of the movable carrier 1, and the absorption boxes 92 arranged at the two ends of the movable carrier 1 suck the grass into the storage chamber through the action of the third air pump 9 and the fourth connecting pipe 91.

The foregoing description is only of the preferred embodiments of the present disclosure and description of the principles of the technology being employed.
