Description

Extirpator

Technical field

The present invention relates to a kind of extirpator, belong to agricultural and horticulture extirpator field.

Background technology

So far, all kinds of extirpators that use both at home and abroad, main purpose is the labour intensity while improving uprooting weed efficiency, reduction uprooting weed.

General extirpator is of a great variety, is mainly divided into complex structure and simple two large classes, and baroque extirpator uprooting weed is effective, can the upright uprooting weed of people, but Heavy Weight, complicated operation, easily fatigue works long hours; Extirpator simple in structure is lightweight, the uprooting weed of need to bending over, and uprooting weed weak effect, can not accomplish that uprooting weed digs up the roots, and bends over for a long time to bring fatigue to people.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of simple in structure, lightweight, uprooting weed is efficient, laborsaving, easy and simple to handle, without the extirpator of bending over, solved baroque extirpator Heavy Weight, complicated operation, work long hours easily tired; Solved the simple extirpator of structure need to bend over uprooting weed, uprooting weed weak effect, can not accomplish that uprooting weed digs up the roots, bend over for a long time to bring tired problem to people.

In order to solve the problems of the technologies described above, technical scheme of the present invention has been to provide a kind of extirpator, it is characterized in that, comprise extirpator main body, extirpator main body is the metal pipe of a hollow bending 90 degree, one end of extirpator main body is handle, the outside of handle is provided with taper knob, the other end of extirpator main body and pedal welding, pedal is provided with foot-operated plate hole, 90 degree places of extirpator main body are provided with otch, through in the extirpator main body of otch, be provided with push rod, the upper end of push rod is connected with push-pull button, the nearly middle part of push rod is provided with the second butterfly limit, the top on the second butterfly limit is provided with spring, the lower end of push rod is provided with the first butterfly limit, weld with slide block through the board butterfly on foot-operated plate hole and board is lateral opening the end of push rod lower end, slide block is provided with a plurality of slide block pawl nails hole, and align with the board pawl nail hole on board, in board pawl nail hole and slide block pawl nail hole, be provided with pawl nail, pedal is connected with board.

Preferably, the inner side of described otch is through pushing the circular arc of backward interior moulding.

Preferably, between described spring and the second butterfly limit, otch, be respectively equipped with the first pad, the second pad.

Preferably, on described slide block, be evenly provided with a plurality of slide block pawl nails hole.

Preferably, the central diameter in described slide block pawl nail hole is more smaller than the central diameter in board pawl nail hole.

Preferably, the surface of described pawl nail is provided with straightedge.

The present invention is simple in structure, lightweight, easy and simple to handle, and its board butterfly is lateral opening to be coordinated with the first butterfly limit of push rod head, guarantees the location of push rod and only has a degree of freedom sliding up and down, the rotation of restriction push rod.It is in order to reduce the friction in the slide block pawl nail hole on pawl nail and slide block that pawl is followed closely the design of surperficial straightedge, thereby can reduce the manufactured materials of spring, reduces costs, weight reduction.By the present invention, make the operating personnel of uprooting weed without bending over, can operate on one's feet, very laborsaving, uprooting weed is efficient.

Embodiment

For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

The present invention is a kind of extirpator, as Fig. 1, Fig. 2, Fig. 4, Fig. 5, shown in Fig. 6, it comprises extirpator main body 2, extirpator main body 2 is the metal pipe that a hollow bending 90 is spent, one end of extirpator main body 2 is the handle of extirpator, handle jacket is sleeve 1 on the other hand, solder joint 6 welding of the other end of extirpator main body 2 and pedal 5, in pedal 5, have a foot-operated plate hole 14, the 90 degree places in extirpator main body 2 open a kerf 7, its inner side is molded into a circular arc 8 through pushing in backward, through in the extirpator main body 2 of otch 7, there is a push rod 9, the upper end of push rod 9 connects push-pull button 10, the the second butterfly limit 19 that has an extrusion modling at the nearly middle part of push rod 9, one first pad 20 is being worn on the top on the second butterfly limit 19, the first pad 20 tops are installed with a spring 21, at otch 7 places near extirpator main body 2, be installed with one second pad 22, the lower end of push rod 9 is squeezed into the first butterfly limit 12, through foot-operated plate hole 14 and board butterfly lateral opening 13, solder joint 11 welding slide blocks 4 in push rod 9 ends, lower end, on slide block 4, evenly have a plurality of slide block pawl nails hole 15, and align with board pawl nail hole 16, but the central diameter in slide block pawl nail hole 15 is more smaller than the central diameter in board pawl nail hole 16, in board pawl nail hole 16 and slide block pawl nail hole 15, be installed with pawl nail 3, pawl is followed closely 3 surfaces straightedge 24 (as shown in Figure 8), board 17 connects by screw 18 with pedal 5.

As shown in Figure 2, structural representation for extirpator assembling section inside, this figure is also that extirpator is under the thrust of spring 21, push rod 9 moves downward, until push rod step 23 (as shown in Figure 7) gear stops to board face 25, pawl is followed closely 3 these time delay slider bore 15 and is opened, and is split into extirpator readiness for operation.

As shown in Figure 3, for careless schematic diagram is grabbed in extirpator work, namely extirpator operator holds taper knob 1 place of extirpator, pawl nail 3 is aimed on the weeds that will pull out, tramp with one's feet and step on sole 5, under the effect of pedal force, pawl nail 3 gos deep in weeds earth around, earth promotes slide block 4 and is slided along board butterfly lateral opening 13 in the first butterfly limit 12 of push rod 9, because align with board pawl nail hole 16 in slide block pawl nail hole 15, but the central diameter in slide block pawl nail hole 15 is more smaller than the central diameter in board pawl nail hole 16, so pawl nail 3 has formed Five-link machine with slide block pawl nail hole 15, pawl is followed closely 3 inward collapsibles, together with the earth of weeds and weeds root, catch, push-pull button 10 is held in operator's one have gentle hands, mention extirpator simultaneously together with another hand, the main root of weeds is firmly held and is pulled up by pawl nail 3 with earth together, when handgrip push-pull button 10 is decontroled, push rod 9 is at the first pad 20, spring 21, under the effect of the second pad 22, move downward, push rod 9 band movable sliders 4 move together, pawl nail 3 is outwards launched, at this moment by the pawl nail 3 weeds roots of holding tightly and earth along with the promotion 9 of slide block 4 and the outside expansion of pawl nail 3, weeds drop from the pawl nail 3 of extirpator together with root.

Board butterfly lateral opening 13 coordinates with the first butterfly limit 12 of push rod 9 heads, is guarantee the location of push rod 9 and only have a degree of freedom sliding up and down the rotation of restriction push rod 9.

Straightedge 24 design that pawl is followed closely 3 surfaces is in order to reduce the friction in the slide block pawl nail hole 15 on pawl nail 3 and slide block 4, thereby can reduce the manufactured materials of spring 21, reduces costs, weight reduction.
