TECHNICAL FIELD
[0001] The present application relates to the technical field of soil remediation, in particular to an ecological garden soil remediation device. BACKGROUND
[0002] In the field of ecological garden soil remediation, it is a core requirement to accurately deliver microbial agents or remediation liquid to deep soil. Currently, the mainstream deep intervention technology mainly relies on traditional underground injection devices. These devices usually have a hollow injection rod driven by hydraulic pressure, and a slotted cutter head is provided at the end of the rod body. The cutter head is inserted into the soil by pressing down, and the liquid is released through the liquid outlet on the rod wall during the lifting process.
[0003] However, such traditional design has several inherent defects. First, the liquid outlet at the bottom of the injection rod is easily blocked by soil, roots or clay particles during insertion, resulting in injection failure. Second, the wing-shaped cutter head structure will disturb and hook the surrounding soil during lifting, not only increasing the operation resistance, but also causing secondary damage to the soil aggregate structure that needs to be protected, which is contrary to the original intention of ecological remediation. In addition, the liquid release is not coordinated with the movement of the rod body, often causing the liquid to be released at a single depth, which cannot form a uniform vertical treatment zone, and the remediation effect is greatly reduced. SUMMARY

[0007] Preferably, the liquid path control mechanism further comprises an outer ring one-way valve, the outer ring one-way valve is installed at the through hole of the pressure boosting piston and surrounds the outer side of the inner pressure rod, and the conduction direction of the outer ring one-way valve is from the boosting cylinder cavity above the pressure boosting piston to the cavity of the injection rod; the driving liquid path and the outer ring one-way valve form a sequential action loop, so that when the injection rod is lifted, the liquid medicine preferentially pushes the fender to expand through the driving liquid path, and then pushes the outer ring one-way valve to open to supply a large amount of liquid to the cavity of the injection rod.

[0018] The both sides of injection rod 2 bottom are provided with liquid outlet 23, and liquid outlet 23 is located the upper side of wing -shaped edge of slit cutter head 3 instead of at the tip of injection rod 2, can prevent soil from plugging liquid outlet 23 in the process of insertion, and the top of pressure cylinder 1 is installed with one -way valve 11, and is communicated with liquid storage tank through one -way valve 11, and the flow direction of one -way valve 11 is from liquid storage tank to the inside of pressure cylinder 1, when excavating, the power device of hydraulic system presses down injection rod 2 through power connecting rod 22, vertically inserts slit cutter head 3 into soil through slit cutter head 3, and slit cutter head 3 vertically splits soil and forms a narrow slit, and the power device of hydraulic system pulls up power connecting rod 22, drives injection rod 2 to move up as a whole, and the pressure of last liquid medicine is raised by the space of pressure cylinder 1 being pressed by pressure intensifier piston 21, and the bacteria solution is pressed out from liquid outlet 23 through hollow cavity, and the bacteria solution diffuses in the slit of split soil and the tiny crack and pore around it under high pressure, and, continuously injects during the process of slowly lifting injection rod 2, can form a continuous treatment zone in the vertical direction, instead of an isolated point, greatly improves the uniformity of treatment.
[0019] Please refer to Figures 2-4, the injection rod 2 two sides liquid outlet 23 is equipped with the embedded groove, the embedded groove extends to the top of the slitting cutter head 3 in the form of arc, and the fender 24 is movably installed at the embedded groove, the top of the fender 24 is installed with the rotating shaft 241, the fender 24 is movably connected with the outer wall of the injection rod 2 through the rotating shaft 241, when the hydraulic system pushes the injection rod 2 to be vertically inserted into the soil, the fender 24 is closed and is received into the embedded groove, the inner pressure rod 26 is fixedly connected at the middle through hole of the booster piston 21, the diameter of the inner pressure rod 26 is less than the diameter of the through hole, the outer ring one-way valve 25 is fixedly installed at the outer side through hole of the top end of the inner pressure rod 26, the conduction direction of the outer ring one-way valve 25 is from the inside of the booster cylinder 1 to the outside of the inner pressure rod 26 in the injection rod 2, the bottom of the inner pressure rod 26 is communicated with the support cavity 261, the support cavity 261 movably sleeves the support arc rod 242, the tail end of the support cavity 261 is equipped with a limiting device to avoid the support arc rod 242 from falling off from the support cavity 261, and the outer end of the support arc rod 242 is fixedly connected to the inner side of the bottom of the fender 24.
[0020] Please refer to Figures 5-6 When the hydraulic system power device pulls the power connecting rod 22 upwards, drives the injection rod 2 to move upwards as a whole, the high-pressure liquid on the upper side of the booster piston 21 first enters the support cavity 261 through the inner pressure rod 26, pushes the two side support arc rods 242 to move outwards through the high-pressure liquid, and then pushes the bottom of the fender 24 to open outwards around the rotating shaft 241, the support arc rod 242 stops moving when it moves outwards to the limiting device, and the booster piston 21 continues to move upwards to make the liquid on the upper side pressurize the outer ring one-way valve 25 to open, the remaining liquid passes through the outer ring one-way valve 25 to enter the space outside the inner pressure rod 26 in the injection rod 2, and is discharged from the liquid outlet 23, at this time, the fender 24 blocks the soil from blocking the liquid outlet 23 when moving upwards, and avoids the wing-shaped structure of the slitting cutter head 3 from generating resistance by hooking the soil when moving upwards, after completing the injection, before digging again, when the booster piston 21 moves downwards, the liquid in the inner pressure rod 26 is adsorbed by the negative pressure in the upper cavity of the booster cylinder 1, drives the support cavity 261 to move inwards to reset, drives the fender 24 to be received into the embedded groove for the next insertion work, and in the pressing and puncturing stage, the fender 24 is closed and is received into the embedded groove of the injection rod 2, to avoid generating too much resistance by friction with the soil.
[0021] The working principle of the use method of the present application is as follows: When in use, the hydraulic power device starts to work, pushing down the power connecting rod 22, which drives the injection rod 2 and the slit cutter 3 to vertically insert into the soil. The shuttle-shaped or wing-shaped design of the slit cutter 3 enables it to vertically split the soil like a knife, forming a narrow slit, thereby minimizing the extrusion and damage to the surrounding soil structure. During the downward movement of the injection rod 2, the booster piston 21 fixed at the top end of the injection rod 2 moves downward synchronously in the booster cylinder 1, so that the space above the booster piston 21 forms a negative pressure. This negative pressure sucks the liquid medicine in the external storage tank through the one-way valve 11 at the top end and fills the space. At this stage, the fender 24 is tightly closed and fits in the embedded groove of the injection rod 2 to avoid increasing the downward resistance. Through the control of the hydraulic system or the depth sensor, when the slit cutter 3 reaches the predetermined repair depth, the downward movement stops.
[0022] After reaching the predetermined depth, the hydraulic power device reverses, pulling up the power connecting rod 22, which drives the entire injection rod 2 system to start slowly moving upward. At this time, the booster piston 21 moves upward in the booster cylinder 1, compressing the liquid medicine in the chamber above it. Under pressure, the liquid medicine first enters the bottom support cavity 261 through the internal pressure rod 26, pushing the support arc rod 242 outward, which in turn pushes the bottom of the fender 24, causing the fender 24 to rotate outward around the rotating shaft 241, forming a protective cover covering the outside of the liquid outlet 23, effectively preventing the surrounding soil from rushing into or blocking the liquid outlet 23 during the upward movement.
[0023] When the support arc rod 242 moves outward to the limiting device and the fender 24 is fully expanded, the booster piston 21 continues to move upward, the liquid pressure further increases, and the outer ring one-way valve 25 is opened, a large amount of liquid medicine enters the hollow cavity of the injection rod 2 through the outer ring one-way valve 25 and is shot out from the liquid outlet 23 protected by the fender 24 at high speed. The liquid medicine penetrates into the split soil gap and its surrounding micro-pores under high pressure, and this injection process is synchronized with the slow and continuous upward movement of the injection rod 2, so that the liquid medicine forms a continuous and uniform treatment band in the vertical direction, greatly improving the uniformity and effect of the repair.
[0024] After a single upward injection is completed, the device can be moved to the next injection point to repeat the "downward puncture-upward injection" process. When it is pressed down again, the negative pressure generated in the booster cylinder 1 will replenish fresh liquid medicine through the one-way valve 11, while the liquid medicine in the support cavity 261 will be sucked back, driving the support arc rod 242 and the fender 24 to retract to the closed state, preparing for the next puncture operation.
