The inside of hollow structure is socketed a valve core plate, the valve core plate the end face positioned at the bellmouth fix a construction profile and
One end inside the consistent conical plate of the construction profile of the bellmouth, the other end of the valve core plate and the second hollow structure
Between fix and filled out inside a helical spring, the sealing space that first hollow structure and second hollow structure are constituted
Filled with hydraulic oil.
Preferably, the electromagnet includes the iron core that outside is socketed with coil.
Preferably, the current input terminal of the coil connects a current switch by wire.
Preferably, the central shaft is in one end away from electromagnet positioned at the annular stop ring and the first hollow structure
Between axis body be provided with multiple open tubular columns.
Preferably, during the axial line of multiple open tubular columns is generally aligned in the same plane.
Preferably, the axial line of multiple open tubular columns is evenly distributed at the conplane circumference.
Preferably, the two ends of the central shaft are socketed in the inside of two rollers by bearing.
Preferably, being provided with Cleat structures at the circumference of the roller.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention can realize equidistant borehole, in addition, this practicality can realize quick borehole work under semiautomatic action
Make, it is time saving and energy saving, the efficiency of work can greatly be accelerated, and also the device is mechanical mechanism, it is not necessary to other energy conducts
Auxiliary, practical simplicity.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, a kind of embodiment that the present invention is provided:A kind of crops chemical fertilizer hole-tapering device, including inside
For the central shaft 1 of the first hollow structure 4, the inside of described one end of central shaft 1 is provided with electromagnet, the first of the central shaft 1
Hollow structure 4 is socketed an annular stop ring 5 in the inside of one end positioned at electromagnet, and first hollow structure 4 is positioned at ring
Shape spacing ring 5 and its be located at the inside of electromagnet one end between place a permanent magnet 6, the axis body surface of the central shaft 1 is set
Have multiple with its integral structure open tubular column 11, the open tubular column 11 is provided centrally with the second hollow structure 12, the sky
One end of stem 11 is provided with the through-hole structure 10 for connecting the hollow structure 12 of the first hollow structure 4 and second, described hollow
The end of post 11 is provided with taper header structure 13, and the taper header structure 13 is internally provided with bellmouth 18, described second
The inside of hollow structure 12 is socketed a valve core plate 15, and the valve core plate 15 fixes a structure in the end face positioned at the bellmouth 18
The profile conical plate 17 consistent with the construction profile of the bellmouth 18, the other end of the valve core plate 15 and the second hollow knot
A helical spring 16,12 structures of first hollow structure 4 and second hollow structure are fixed between one end inside structure 12
Into sealing space inside be filled with hydraulic oil.
The electromagnet includes the iron core 8 that outside is socketed with coil 7;The current input terminal of the coil 7 is connected by wire 9
A current switch is connect, electromagnetism operation principle is realized;The central shaft 1 is positioned at the hollow structure 4 of annular stop ring 5 and first
Axis body between one end away from electromagnet is provided with multiple open tubular columns 11;The axial line of multiple open tubular columns 11 is located at same
In plane;The axial line of multiple open tubular columns 11 is evenly distributed at the conplane circumference, realizes equidistant effect;
The two ends of the central shaft 1 are socketed in the inside of two rollers 2 by bearing;Anti-skid bulge is provided with the circumference of the roller 2
Structure 3, realizes rolling action.
Specifically used mode:In present invention work, in use, the device is pushed into suitable position, then by bellmouth
18 alignments need the position of borehole, then can be achieved to promote by hand push central shaft 1, and in pushing course, pass through electric current
Switch constantly opens and closes the electric current led in coil 7, according to electromagnetic conversion principle so that iron core 8, can produce and permanent magnetism
Body 6 is in opposite end magnetic identical magnetic pole, when bellmouth 18 moves to basal surface, closes electric current now, now spiral bullet
Spring 16 resets permanent magnet 6 in the presence of itself, meanwhile, bellmouth 18 can dig out soil now, when bellmouth 18
Dig out after soil, firing current, now, according to identical charges repel each other the principle that there is a natural attraction between the sexes, enable to permanent magnet 6 to promote hydraulic pressure
Oil, soil is ejected, similarly, you can realize quick borehole.
