Compared with the prior art, the invention has the following beneficial effects:

1. can make this device adapt to the not lawn of the high growth of co-altitude through elevation structure, drive through the motor and remove the wheel rotation, because elevation structure's bottom both sides all are equipped with infrared sensor, prune and be equipped with the controller in the casing, when this trimming means's both sides are when removing the process, avoid this device to break away from the lawn through infrared sensor, meet the grass-free area back when one side of trimming means, can make to remove the wheel through the controller and avoid the grass-free area to prune, avoid other plants on trimming means pruning sword lawn.

2. In-process on lawn is pruned to this device, rotation through the drive axostylus axostyle, it rotates to drive runner, because the axial plane of drive runner is equipped with the arc rotary tank, because the both ends of arc rotary tank all are close to the both ends of drive runner respectively, thereby make the column of stirring drive first catch bar and carry out reciprocating motion, when first catch bar carries out reciprocating motion with the second catch bar, can make to right the dysmorphism board and insert the lawn bottom, when ascending, the grass that the drive was stepped on rights.

3. Because right the dysmorphism board and be equipped with spacing flat board, the one end that linkage slope extension board was kept away from to spacing flat board is equipped with the buffering hang plate, can avoid the grass to be blocked absolutely at righting the in-process, the efficiency of righting the structure has been improved, because one side that spacing flat board was kept away from to the bottom of buffering hang plate is equipped with the interlude flat board, the dull and stereotyped other end of interlude is for inserting the inclined plane, the incline direction that inserts the inclined plane is the same with the incline direction of buffering hang plate, can make and right the dysmorphism board and alternate the bottom of being stepped on the lawn more easily, the efficiency of righting is improved, avoid the hourglass to cut.

4. Through first stable splint and the stable splint of second, guaranteed to get the stability of material backup pad, because the both sides central point of getting the material backup pad puts and all is equipped with spacing extension board, and receives spacing dull and stereotyped restriction, has improved the stability of the vertical direction of little grass to the cutting efficiency of cutting knife board has been improved.

5. After the cutting, receive the restriction and the inertia principle of spacing extension board, can make the little grass section of excision receive the bearing of cutting knife board, stably arrange the top of cutting knife board in, when the cutting knife board is close to and receives the material and hinder the piece, because receive the inclination of material hindering the piece with receive the inclination on material inclined plane the same, can block the motion of cutting knife board to make the little grass receive under the circumstances of action of gravity and inertia, fall into and receive the silo, because receive the material spout and keep away from the one end of getting the material backup pad is equipped with reset spring, can make the cutting knife board carry out next cutting work, because the stripper plate the blotter reaches the top of extrusion push pedal is the slope structure, and the inclined plane is in same inclination, when the little grass falls into on the stripper plate, can take the advantage of the situation down, has avoided the forage to fall the wrong position, causes the jam.

6. Because the other end of first extrusion push rod is equipped with linkage structure, through the rotation of driving-disc, can make the linkage change the board and drive first extrusion push rod and carry out opposite direction's reciprocating motion with first linkage push rod to make first extrusion push rod drive the stripper plate and carry out extrusion moulding to the little grass section that falls into, avoided the indiscriminate phenomenon of flying of grass section, improved staff's operational environment's security.

7. Through the fixed intermittent type rotary cam that is equipped with of the other end of fourth linkage push rod to can drive intermittent type slurcam and carry out the protrusion motion along with withdrawing of stripper plate after the interval fixed time, thereby go out the grass group that will take shape through the discharging pipe extrusion, increaseed the recovery efficiency of grass section, simultaneously, because the fixed output of grass group, alleviateed trimming means's heavy burden pressure, reduced the heavy burden pressure on lawn, avoided personnel's repetition to step on.
