Embodiment

In weeding device shown in Fig. 1, two lobate tool rests 7 are placed on driving shaft 1.Integral type cutter and rake teeth are all settled in two front ends of two lobate tool rests 7.Every one end is all the same setting.Integral type cutter and rake teeth 3 and 6 are all settled in tool rest 7 two sides, and these two rake teeths are flexibly connected by screw rod 2 with tool rest 7, and rake teeth 3 and 6 can do both forward and reverse directions 360 ° rotation relative to tool rest 7 around connector screw rod 2.

See Fig. 3,4.The upper end of integral type cutter and rake teeth arranges installing hole 8, for screw rod 2 through it being flexibly connected with tool rest.The oblique outside, front end of rake teeth 6 and form cutter 5.The angle [alpha] 1 in the oblique outside of cutter 5 is 25 ~ 45 °.Integral type cutter on the right side of tool rest shown in Fig. 5 and rake teeth, identical with harrow tooth structure with the integral type cutter on the left of the tool rest shown in Fig. 4, institute's difference is, the direction in oblique outside is just the opposite, and angle [alpha] 2 equals α 1.

Shown in Fig. 2 is inactive state.The point of a knife of cutter 5 is towards the right side, blade (in fact not putting the first edge on a knife or a pair of scissors) towards a left side.Weeding device entirety is rotated by shown in dotted arrow with driving shaft 1, and due to centrifugal action, the integral type cutter at two ends and rake teeth then become the state straight with tool rest 7, when hoeing up weeds, be then in blade incision soil, instead of point of a knife is first cut in soil.Such mode is conducive to protecting cutter.

Due to cutter 5 and cutter 4 oblique outside, so when weeding device circles, cutter 5 and cutter 4 can cut off oblique for the grass on both sides.When cutter 5 and cutter 4 move to soon close to ground, just can realize mowing with pasting, make cutting height be down to zero.

When cutter 5 and cutter 4 also do not touch ground, the vertical grass segmentation aloft in front can be cut off, when cutter 5 and cutter 4 touch ground or afterwards, remaining for front vertical grass (being cut off top) can down cut off again by the cutter of the other end again.Such circulation is gone down, and the vertical grass on ground will be slit into broken section.Therefore such grass-remover not only has mowing function, and that grass can also be cut is very broken, reaches the degree of pulverizing.

Behind cutter incision ground, grass roots can cut off by oblique outer blade.This has dug grass roots compared with simple rake teeth and utilized pulls the mode that strength pulls apart grass roots, better effects if of hoeing up weeds, but also grass roots can be cut broken, reaches the degree of pulverizing equally.

Grass after pulverizing or grass roots scattered on the ground, along with ensuing hoeing up weeds is loosened the soil and ploughed under in soil, fertilizer is rotted in these broken grass (comprising root) fermentation of being more convenient for.

In addition, behind cutter incision ground, also can by loose for topsoil scribing, better effects if of loosening the soil.

If there is larger stone on ground, when such stone encountered by cutter, the cutter 5 of rake teeth 3 and 6 and front end and cutter 4 will make counter-rotation around connector screw rod 2 relative to tool rest 7.At this moment tool rest does not encounter stone, so can also continue to rotate with axle.So tool rest can't damage, also tool rest will be made to stop even making motor stalling so that scaling loss due to the stop of stone.

As shown in Figure 6, three cover 3 lobate tool rests 9,10,11 evenly split on driving shaft 1.The equilibrium of three covers 3 lobate tool rest 9,10,11 is staggered settles (see Fig. 7).
