Specific implementation mode

The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model Define.

Attached Fig. 1 and 2 is please referred to, the utility model embodiment includes：

A kind of adjustment structure on weeder, including trimming roller 1, wheel 2 of beating the grass, rotation seat 3, screw rod 5, sleeve 6, Push rod 7 and motor 8.It trims roller 1 with axial horizontal position to be arranged, trims and be provided with shaft at the axle center of roller 1；Shaft It is provided at both ends with ball bearing 9.The rotary surface for trimming roller 1 is equipped with the blade 10 of multiple row protrusion, and blade 10 is along trimming The axial direction of roller 1 and uniform intervals arrange.Grass structure is removed using roller type, is different from cutting off mode, roller type passes through phase Shear force can uproop weeds, more thoroughly carry out weeds processing, avoid growing repeatedly.In the front side of trimming roller 1 Wheel 2 of beating the grass is set, and wheel 2 of beating the grass is not higher than trimming roller, the axial angles of beat the grass 25 ~ 30 ° of wheel 2 and trimming roller 1 holding.It beats the grass Wheel 2 can gather the weeds of 1 both sides of trimming roller, and angle setting can avoid because trimming drum movement generates outward Extruding force makes the weeds of around it or edge disperse, to improve weeding ratio.Beat the grass wheel 2 rotary surface be provided with Detent projection, it is well known that cutting structure can increase frictional force, and weeds quality is lighter, and the flank of tooth can also play certain Execution.The shaft of wheel 2 of beating the grass is installed on rotation seat 3, and gear 4 for transmission is provided on the mandrel for wheel 2 of beating the grass.Turn Dynamic seat 3 is L-shaped pedestal, and the bottom of rotation seat 3 is provided with run-on point, push rod 7 is also associated on rotation seat 3, during push rod 7 is Blank pipe body, push rod 7 are connect with rotation seat 3 by globular hinge point.Push rod 7 pushes rotation seat 3 to rotate around it a rotation, push rod 7 It is set with sleeve 6 outside.One end of push rod 7 is connected on rotation seat 3, is installed in other end insertion sleeve 6 and on the end and is adjusted Save nut 11.It is also coaxially disposed a screw rod 5 in sleeve 6, is stretched into push rod 7 after one end of screw rod 5 and the cooperation of adjusting nut 11, The other end of screw rod 5 is fixed to 6 upper end of sleeve.Screw rod 5 is driven by motor 8, and when 8 uniform rotation of motor, screw rod 5 can turn therewith Dynamic, due to screw-thread fit, screw rod 5 coordinates with adjusting nut 11, and push rod 7 has been driven to stretch in sleeve 6, and sleeve 6 is fixed Under the premise of, push rod 7 will generate push-and-pull to rotation seat 3, to realize angular adjustment.The adjustment structure is suitable for grass-mowing machine On, it is used to adjust the angle between wheel and trimming roller of beating the grass on grass-mowing machine, based on screw-thread fit, carries out the small model of angle Adjustment is enclosed, stable transmission will not be impacted because of external force, can improve the harmony of equipment entirety.

The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass, is equally included in the patent within the scope of the utility model.
