Specific embodiment
As shown in Figure 1, this soil repairing and treating device, the controlling device for being installed on driving equipment bottom including one, the improvement
Device is entered in soil by the pressure assembly vertical depression in driving equipment, is pushed controlling device by pressure assembly and will be administered
Improvement liquid in device extrudes into soil;
Controlling device includes a mounting plate 70, and a piece down-pressed pole 2 of setting is respectively welded at the angle of bottom four of mounting plate 70,
Bottom connection one First piston bar 13 of setting of down-pressed pole 2, the bottom activity of First piston bar 13 are inserted in a ground inserted link 12,
There is an open-topped liquid storage chamber 22, the sealed bottom of First piston bar 13 is inserted in liquid storage chamber simultaneously inside ground inserted link 12
Entire liquid storage chamber is sealed, a lateral axle sleeve 7 is respectively set in the two sides of the bottom of every ground inserted link 12, and activity is packed into lateral axle sleeve 7
One second piston bar 51, the external of second piston bar 51 are arranged a movable block 5, connect on the movable block 5 of adjacent two ground inserted link 12
A cutting line 16 is connect, when relatively inserted link pushes First piston bar 13, is made by administering liquid ejection second piston bar 51
Cutting line 16 cuts soil along horizontal plane lateral displacement, administers liquid and squeezes out from the liquid aperture that goes out on cutting line 16.
Wherein, movable block 5 is tapered, and one connecting bushing 52 of welding setting, cutting line 16 are one on external tapered surface
The hollow metal thin bar of root, the internal liquid-conveying ducts with a both ends open, respectively liquid aperture is communicated with liquid-conveying ducts out, is cut
The both ends of secant 16 are inserted in connecting bushing 52 respectively and are adhesively fixed.It is (hydraulic by pressure assembly when needing to administer
Power) entire controlling device is pressed into soil, in extrusion process, liquid will be administered from cutting line and go out liquid aperture row
Out, the purpose that side cutting edge goes out liquid can be realized in this way.
Wherein, respectively one first electromagnet 6 of insertion setting, the first electromagnet 6 are in a ring, embedding on the end face of lateral axle sleeve 7
Enter to be arranged in simultaneously gluing hydropexis in the annular groove that lateral 7 end face of axle sleeve opens up, movable block 5 is metal block, with energization
First electromagnet 6 is fixed, the power supply line of the first electromagnet 6 from cabling inside lateral axle sleeve and be inserted into lateral axle sleeve and
In the outlet-pipe 3 being fixedly welded outside ground inserted link, final access is in the control host side of driving equipment, by controlling host control
Power on/off processed.When the first electromagnet 6 must be electric, second piston bar cannot stretch out at this time, and the lateral position of cutting line will not occur
It is mobile, it is at this time the process of longitudinal injection liquid soil, and when needing cutting line to make transverse cuts, need to manually control disconnection
Power supply enables second piston bar to eject under the action of liquid extruding force, realizes the lateral displacement cutting of cutting line, in turn
Realize the injection of lateral liquid soil.
Wherein, outlet-pipe 3 is metal tube, is weldingly fixed in the outside wall surface of lateral axle sleeve 7 and ground inserted link 12.
Wherein, as shown in figure 5, one first sealing piston 131, the first sealing piston is arranged in the bottom of First piston bar 13
The 131 entire liquid storage chambers of sealing, the extrusion channel 55 with a both ends open in lateral axle sleeve squeeze out channel 55 and liquid storage chamber
It communicates, the inner end of the second piston bar 51 is respectively provided with one second sealing piston 54, and the sealing of the second sealing piston 54 squeezes out logical
Road 55, the inside of second piston bar 51 have the feed pathway 53 of a side opening, and the inlet end of feed pathway 53 opens up
In the second sealing piston 54, feed pathway 53 is communicated with channel 55 is squeezed out, and connecting bushing is arranged in the output end of feed pathway 53
52, the improvement liquid in feed pathway 53 is discharged by being pressed into cutting line 16.When pushing the first sealing piston, ground is inserted
Bar position is different, administers liquid and enters in the feed pathway of second piston bar, then is entered in cutting line by pressure extrusion, this
When due to pressure it is very big, the speed of the liquid of discharge is limited, therefore entire second piston bar can be under liquid squeezing action to overhanging
Out, as shown in figure 3, since cutting line is installed on the movable block of second piston bar, therefore after movable block laterally ejects, cutting line
It can make lateral displacement cutting action, and then change lateral position degree, cutting injection is carried out to transverse direction.
In the present embodiment, down-pressed pole 2 is welded and fixed with 70 bottom of mounting plate, passes through at the top of down-pressed pole 2 and First piston bar
Flanged joint is fixed, and ground inserted link and lateral axle sleeve the same side are also provided with a longitudinally disposed sliding slot, embedding on the bottom surface of sliding slot
Enter to be provided with the second electromagnet 21, the access of the second electromagnet 21 passes through control host side in the control host side of driving equipment
Control button controls power on/off, and sliding is packed into a sliding block 11 in sliding slot, and a protrusion 4 is arranged in the outboard end of sliding block 11, and protrusion 4 is inserted into
It in the slot of one limit plate 8 and is adhesively fixed, protrusion 4 is made with sliding block 11 of the metal material of integral type, such as Fig. 2 and Fig. 4 institute
Show.The effect of limit plate 8 is for fixing residence inserted link, so that entirely inserted link will not be downward in cutting line transverse cuts
It is inserted in deeper soil, when the second electromagnet power loss, limit plate lower end surface is contacted with soil surface, with the inserted link that lands
Constantly insertion, limit plate passes through sliding block along sliding slot upward sliding, but once wants transverse cuts, controls the second electromagnet at this time
Must be electric, using magnetic-adsorption sliding block, limit plate relatively fix by inserted link at this time, at this time the pressure in the case where applying to First piston bar
When, whole ground inserted link just will not descending depth again, i.e., eject second piston bar using hydraulic coupling, transverse cuts can be realized
It administers.
Wherein, the inside of First piston bar has a transition passage (not shown), the input terminal setting one of transition passage
Root perfusion tube 14, perfusion tube 14 connect external infusion pump (not shown), and the liquid outlet end of transition passage passes through the first sealing and lives
Plug 131 is administered liquid and is entered in feed pathway across the first sealing piston 131, can carry out fluid infusion in time, very convenient.
Wherein, the section of sliding slot 15 and sliding block 11 is in T-shaped, and anti-limited slip block 11 is separated with sliding slot 15.
The beneficial effects of the present invention are: the present invention is being inserted perpendicularly into after in soil, depth can control to carry out difference
The reparation of the soil horizon of depth, and traversing improvement can be realized, and then carry out to region is administered after the completion of operating in depth
The greater area of input for administering liquid, reduction are longitudinally inserted into number, working efficiency are promoted, so that the utilization rate of soil remediation liquid is more
It is high.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
