Specific embodiment

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.

Referring to Figures 1 and 2, the tea oil tree WEEDING DEVICE of a kind of environment-friendly type, including top plate 1 and bottom plate 2, top plate 1 and bottom plate 2 It is to be square and size is identical, the distance between above-mentioned top plate 1 and above-mentioned bottom plate 2 are 3~6cm, preferred distance 5cm； The edge of above-mentioned top plate 1 and above-mentioned bottom plate 2 is equipped with the notch 10 to match with the trunk of tea oil tree.Above-mentioned top plate 1 and above-mentioned bottom Multiple equally distributed elastic circular rings 3 are installed between plate 2, the middle part of elastic circular ring 3 is equipped with circular hole 30, and top plate 1 is equipped with more The middle part of a circular groove 11, the bottom surface of circular groove 11 is equipped with the multiple and one-to-one first through hole 111 of circular hole 30, bottom plate 2 be equipped with it is multiple with one-to-one second through-hole 21 of first through hole 111, weeds sequentially pass through from bottom to top first through hole 111, Circular hole 30 and the second through-hole 21 are grown, and when downward coping 1, the inner wall that elastic circular ring 3 is extruded rear circular hole 30 is received to central axis Grip the stem of weeds.

Referring to Figure 1 and Figure 3, the middle part of top plate 1 is equipped with third through-hole 12, and the middle part of bottom plate 2, which is equipped with, runs through third through-hole 12 The screw rod 21 of the top of top plate 1 is extended to, the outside of screw rod 21 is socketed with hand-held rod 5, and the outer diameter of the hand-held rod 5 is logical less than third The aperture in hole 12, the outside of hand-held rod 5 are equipped with fixed ring 51, and the outer diameter of the fixed ring 51 is greater than the aperture of third through-hole 12, Gu Ring 51 is determined for being pressed downward above-mentioned top plate 1.The threaded tube 50 to match with screw rod 21, threaded tube 50 are equipped in hand-held rod 5 Height be greater than the height of screw rod 21 so that bottom plate 2 rises squeezes elastic circular ring 3 enough, the top edge of circular hole 30 is to contract.Hand The top of shadoof 5 is equipped with the handle 52 in inverted " j " font, facilitates extraction WEEDING DEVICE, and the bottom surface of bottom plate 2 is equipped at least three The bundle the thin end of the scroll 22 extended downwardly, the line pricked between the thin end of the scroll 22 are in polygon, are preferably provided with four bundle the thin end of the scroll 22, prick the thin end of the scroll 22 and divide It is not located at four edges of bottom plate 2, pricks the thin end of the scroll 22 and makes bottom plate 2 fixed on the ground, will not be rotated together with hand-held rod 5.

With continued reference to Fig. 1 and Fig. 2, the toroidal cavity 31 for water, the top edge of elastic circular ring 3 are equipped in elastic circular ring 3 Equipped with the water hole 112 that several are connected to circular groove 11, which is uniformly distributed around first through hole 111, rainwater or It irrigates spray water first to flow in above-mentioned circular groove 11, the water hole 112 that water carries over 11 bottom surface of circular groove flows to toroidal cavity 31 Middle collection.

Referring to FIG. 1, FIG. 2 and FIG. 4, the aperture of circular hole 30 is gradually increased tapered shape from top to bottom, and the conical surface of circular hole 30 is oblique Degree is 45 °~60 °, and preferably gradient is 50 °, and it is upward that the aperture on the bottom edge of circular hole 30 enables greatly more weeds to carry over the conical surface It grows, further increases uprooting weed efficiency, meanwhile, the strength that the top of the circular hole 30 after being squeezed clamps the stem of weeds is big, pulls out The success rate of careless weeds is high.The surface of the top edge of circular hole 30 is equipped with multiple protrusions 301 extended to the central axis of circular hole 30, this is convex Portion 301 is in four sides cone-shaped, and when the top edge of circular hole 30 is tightened, the tip of protrusion 301 penetrates the epidermis of the stem of weeds, is increased Frictional force between the top edge and weeds of circular hole 30 further promotes uprooting weed success rate.

With continued reference to Fig. 1 to Fig. 3, when uprooting weed, rotating handle 52 rotates down hand-held rod 5 on screw rod 21, hand-held rod 5 On fixed ring 51 be pressed down against top plate 1, top plate 1, which slowly declines, to be squeezed after elastic circular ring 3 deforms, the water in above-mentioned toroidal cavity It diffuses out from water hole into circular groove, circular groove not only prevents water from diffusing out the outer of top plate 1, water flow can also be guided in The first through hole in portion, water successively runs underneath to the root of weeds along the inner wall of first through hole, circular hole 30 and the second through-hole, to weeds The surrounding soil of root has wetting fluffing action, reduces the bundle soil fertility of the root of weeds, the top of circular hole 30 be gradually reduced to The stem for clamping weeds, is lifted up top plate 1 and bottom plate 2, weeds can be extracted easily, and the uprooting weed time is short, high-efficient.

The WEEDING DEVICE of the utility model passes through the configuration of the elastic circular ring 3 between top plate 1 and bottom plate 2, elastic circular ring 3 Middle part is equipped with hole, and radially gradually smaller circular hole 30, the conical surface for guiding more weeds to carry over circular hole 30 are grown upwards, circular hole 30 Multiple protrusions of top edge there is anti-skidding effect, and circular hole 30 keeps WEEDING DEVICE permeability good；When downward coping 1, Elastic Circular 3 deformation of ring shrinks the top of circular hole 30 to central axis, and the water in elastic circular ring 3 is diffused out from above-mentioned water hole, and water is round recessed The first through hole at flow direction middle part, the inner wall that water carries over first through hole run underneath to the root of weeds, water the soil around root in slot Earth effectively reduces the bundle soil fertility of the root of weeds, and the top of circular hole 30 is gradually reduced to the stem for clamping weeds, is lifted up top Plate 1 and bottom plate 2, weeds can be extracted easily, and can once extract more weeds, and the uprooting weed time is short, high-efficient；And pass through hand-held rod 5 setting, the height that screw rod 21 rises in threaded tube 50 can flexible modulation so that circular hole 30 top edge shrink size can It adjusts, adapts to the different size of weeds of stem, be drawn up conveniently, further increase the efficiency of uprooting weed, simple and convenient, uprooting weed Mode is environmentally protective, and hand-held rod 5 can separate exclusive use, and multiple identical WEEDING DEVICEs can be used in conjunction with same hand-held rod 5, save equipment cost.

The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model For.
