A high-efficiency garden soil remediation device

Abstract

This invention relates to the field of soil remediation technology and discloses a high-efficiency soil remediation device for gardens, including a storage roller installed at the rear of a tractor. This invention achieves the distribution of remediation fluid to different depths of the soil through the synergy of a sleeve structure and a squeeze plug design. After the sleeve is inserted into the soil, the outer spray nozzle penetrates into the middle and deep layers, while the inner nozzle corresponds to the surface layer, creating a depth difference. To match the higher remediation requirements of the middle and deep layers, this invention uses first, second, and third squeeze plugs with successively decreasing diameters, with a larger diameter difference between the second and third squeeze plugs. When the hollow rod moves the squeeze plugs downwards, the combination with the larger diameter difference generates a stronger squeezing force on the lower storage chamber, resulting in a greater spray volume of remediation fluid in the middle and deep layers than on the surface. This method relies on the quantitative distribution based on the physical properties of the mechanical structure, eliminating the need for additional control devices. It ensures stable proportions and avoids errors from manual adjustment, thereby solving the problem of excessive spraying on the surface and insufficient spraying in deeper layers in traditional methods, significantly improving the utilization efficiency of the remediation fluid.

Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, specifically, it relates to a highly efficient soil remediation device for gardens. Background Technology

[0002] In the field of garden soil remediation, the precise application of remediation solutions is crucial for improving soil quality and ensuring healthy plant growth. Garden plants exhibit a significant depth distribution characteristic: the absorbing roots responsible for nutrient and water uptake are primarily concentrated in the deep soil layers. This area serves as a critical interface for material exchange between plants and soil, and its physicochemical properties directly determine the plant's growth status: porosity affects root respiration efficiency, organic matter content restricts nutrient supply capacity, and pollutant concentration relates to the safety of plant physiological metabolism. In contrast, the topsoil primarily serves a physical cover function, with sparsely distributed plant roots, and its demand for remediation solutions is significantly lower than that of the middle and deep soil layers. Furthermore, excessive spraying of remediation solutions onto the topsoil may disrupt its ecological balance.

[0003] However, existing equipment fails to accurately distinguish this layered demand: some equipment can only spray the soil surface, and the remediation solution cannot penetrate into the middle and deep root active areas, so the key soil environment where plant roots are located cannot be effectively improved; other equipment can cover multiple layers of soil, but lacks a differentiated control mechanism, and the amount of remediation solution sprayed in the middle and deep layers and the surface layer tends to be the same, which not only causes insufficient remediation in the middle and deep layers and affects the remediation effect, but also leads to an excess of remediation solution in the surface layer, resulting in a waste of resources.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A highly efficient soil remediation device for gardens includes a storage roller installed at the rear of a tractor.

[0006] The storage roller is filled with remedial fluid, and several pairs of sleeves are installed around the storage roller. The sleeves are used to insert into the soil and deliver the remedial fluid. The insert has three evenly distributed positioning blocks installed inside. An upper liquid storage chamber and a lower liquid storage chamber are provided between adjacent positioning blocks. Spray nozzles are opened on the two positioning blocks near the outer side and the side wall of the insert. The three positioning blocks are respectively movably connected to a first extrusion plug, a second extrusion plug, and a third extrusion plug. The diameters of the first extrusion plug, the second extrusion plug, and the third extrusion plug decrease sequentially, and the difference between the diameters of the first extrusion plug and the second extrusion plug is less than the difference between the diameters of the second extrusion plug and the third extrusion plug. A hollow rod is installed between the first extrusion plug, the second extrusion plug, and the third extrusion plug. A positioning shaft is installed inside the storage roller. A protrusion is installed at the bottom of the positioning shaft and is aligned directly downwards. The protrusion is used to lift the hollow rod downwards. The hollow rod moves downward, causing the first, second, and third squeeze plugs to move downward simultaneously, thereby squeezing the repair fluid inside the upper and lower liquid storage chambers and discharging it through the corresponding spray nozzles. The liquid content sprayed from the spray nozzle closer to the outside is greater than that from the other spray nozzle.

[0007] In a preferred embodiment of the present invention, a fixed shaft is rotatably mounted through the end face of the storage roller. One end of the fixed shaft is fixedly connected to the positioning shaft, and a connecting seat is welded to the other end of the fixed shaft. An arched bracket is mounted on the connecting seat, and a reinforcing rib is installed at the bend of the arched bracket. The reinforcing rib is in an inclined state. A connecting frame is mounted on the connecting seat, and an insert shaft is mounted on the connecting frame. The insert shaft is used to connect with the bracket at the rear of the tractor.

[0008] In a preferred embodiment of the present invention, the side wall of the storage roller is provided with a liquid injection port, and a sealing plug is installed on the liquid injection port by screwing on it. The sealing plug is used to seal the storage roller to prevent liquid leakage. The end of the insert is chamfered to facilitate insertion of the insert into the soil.

[0009] In a preferred embodiment of the present invention, a synchronizing seat is installed on the top of the hollow rod, and a ball bearing is installed on the synchronizing seat, the ball bearing being in contact with the end face of the positioning shaft.

[0010] In a preferred embodiment of the present invention, both the second and third squeeze plugs are provided with drain ports. One end of each drain port is connected to the inner cavity of the hollow rod, and the other end is connected to the upper and lower liquid storage chambers, respectively. The hollow rod is also provided with an inlet port, which is connected to the inner cavity of the storage roller. Liquid in the storage roller enters the hollow rod through the inlet port and is fed into the upper and lower liquid storage chambers through the drain ports. As the hollow rod moves downward, the inlet port is covered and sealed by the sliding cover installed on the sleeve, and the two drain ports slide and seal inside the corresponding positioning blocks to ensure the sealing of the upper and lower liquid storage chambers.

[0011] In a preferred embodiment of the present invention, a synchronization plate is installed on the side wall of the hollow rod, and a limiting rod is movably provided at both ends of the synchronization plate. The bottom of the limiting rod is installed in the inner cavity of the storage roller, and a limiting plate is installed on the top of the limiting rod. The diameter of the limiting plate is larger than the diameter of the limiting rod, and the limiting plate is used to prevent the synchronization plate from separating from the limiting rod.

[0012] In a preferred embodiment of the present invention, a limiting spring is sleeved on the limiting rod, and the limiting spring is always in a compressed state. One end of the limiting spring is engaged with the bottom of the synchronization plate, and the other end of the limiting spring is engaged with the inner wall of the storage roller. The elastic force of the limiting spring is used to push the hollow rod to fit against the surface of the positioning shaft.

[0013] In a preferred embodiment of the present invention, a plurality of pairs of card seats are installed on the inner side wall of the storage roller, and the card seats are placed on both sides of the corresponding insert sleeve. A stirring plate is rotatably installed on the card seats. A pressure arm is installed on one end of the stirring plate. One end of the pressure arm is slidably connected to the synchronous plate. The synchronous plate moves down to squeeze the pressure arm to rotate, thereby driving the stirring plate to deflect and stir the repair liquid.

[0014] In a preferred embodiment of the present invention, a retaining shaft is installed at the rotation center of the pressure arm, and both ends of the retaining shaft are rotatably connected to the retaining seat. A torsion spring is sleeved on the retaining shaft, one end of the torsion spring is engaged with the retaining seat, and the other end of the torsion spring is engaged with the side wall of the stirring plate.

[0015] In a preferred embodiment of the present invention, a side plate is installed on the side wall of the synchronization plate, a slide rod is installed on the side plate, a strip groove is opened on the pressure arm, and the slide rod is slidably disposed inside the strip groove.

[0016] Compared with the prior art, the present invention has the following advantages: This invention achieves precise distribution of remediation fluid to different soil depths through the synergy of a sleeve structure and a squeeze plug design. After the sleeve is inserted into the soil, the outer spray nozzle penetrates into the middle and deep layers, while the inner nozzle corresponds to the surface layer, creating a natural depth difference. To match the higher remediation requirements of the middle and deep layers, this invention uses first, second, and third squeeze plugs with successively decreasing diameters, with a larger diameter difference between the second and third squeeze plugs. When the hollow rod moves the squeeze plugs downward, the combination with the larger diameter difference generates a stronger squeezing force on the lower liquid storage chamber, resulting in a greater amount of remediation fluid sprayed into the middle and deep layers than into the surface layer. This method relies on the quantitative distribution based on the physical properties of the mechanical structure, eliminating the need for additional control devices. It ensures stable proportions and avoids errors from manual adjustment, thereby solving the problem of excessive spraying to the surface layer and insufficient spraying to the deep layer in traditional methods, and significantly improving the utilization efficiency of the remediation fluid.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0021] like Figures 1 to 9As shown, a high-efficiency soil remediation device for gardens includes a storage roller 1 installed at the rear of a tractor.

[0022] The storage roller 1 is filled with remediation fluid, and several pairs of inserts 12 are installed around the storage roller 1. The inserts 12 are used to insert into the soil and transport the remediation fluid. The insert 12 has three evenly distributed positioning blocks 121 installed inside. An upper liquid storage chamber 122 and a lower liquid storage chamber 123 are provided between adjacent positioning blocks 121. Spray nozzles 124 are opened on the two positioning blocks 121 near the outside and the side wall of the insert 12. The three positioning blocks 121 are respectively movably connected to a first extrusion plug 133, a second extrusion plug 134, and a third extrusion plug 135. The diameters of the first extrusion plug 133, the second extrusion plug 134, and the third extrusion plug 135 decrease sequentially, and the difference in diameter between the first extrusion plug 133 and the second extrusion plug 134 is less than the difference in diameter between the second extrusion plug 134 and the third extrusion plug 135. A hollow rod 13 is installed between the first extrusion plug 133, the second extrusion plug 134, and the third extrusion plug 135. A positioning shaft 15 is installed inside the storage roller 1. A protrusion 151 is installed at the bottom of the positioning shaft 15, and the protrusion 151 is aligned directly downwards. The protrusion 151 is used to lift the hollow rod 13 downwards. The hollow rod 13 moves downward, causing the first squeeze plug 133, the second squeeze plug 134, and the third squeeze plug 135 to move downward simultaneously. This squeezes the remediation fluid inside the upper and lower storage chambers 122 and 123, discharging it through the corresponding spray nozzles 124. The spray nozzles closer to the outer edge have a higher fluid content than the other nozzles. This structural design utilizes the difference in squeeze plug diameters to achieve differentiated spraying of the remediation fluid, allowing deeper soil layers to receive more remediation fluid, meeting their higher remediation needs and laying the foundation for subsequent efficient remediation.

[0023] like Figures 1 to 9 As shown in the specific embodiment, a fixed shaft 11 is rotatably mounted through the end face of the storage roller 1. One end of the fixed shaft 11 is fixedly connected to the positioning shaft 15, and the other end of the fixed shaft 11 is welded to a connecting seat 111. An arched bracket 112 is mounted on the connecting seat 111, and a reinforcing rib 115 is installed at the bend of the arched bracket 112. The reinforcing rib 115 is in an inclined state. A connecting frame 113 is mounted on the connecting seat 111, and an insert shaft 114 is mounted on the connecting frame 113. The insert shaft 114 is used to connect with the bracket at the rear of the tractor. These connection structures ensure the stability of the connection between the device and the tractor. At the same time, the fixed connection between the fixed shaft 11 and the positioning shaft 15 provides a basis for the rotation of the storage roller 1 and the stationary position of the positioning shaft 15, ensuring the smooth generation of subsequent relative motion and ensuring the stable operation.

[0024] like Figures 1 to 9As shown, the storage roller 1 further includes an injection port 16 on its side wall. A sealing plug 161 is screwed onto the injection port 16 to seal the storage roller 1 and prevent liquid leakage. The end of the insert 12 is chamfered to facilitate insertion into the soil. The design of the injection port 16 and the sealing plug 161 facilitates the injection and storage of the remediation fluid and prevents leakage. The chamfered end of the insert 12 makes it easier to insert into the soil, ensuring that the remediation fluid can be delivered to the required depth and improving the practicality of the device. Example

[0025] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, a synchronizing seat 153 is mounted on the top of the hollow rod 13, and ball bearings 152 are mounted on the synchronizing seat 153. The ball bearings 152 are in contact with the end face of the positioning shaft 15. The ball bearings 152 reduce the friction between the synchronizing seat 153 and the positioning shaft 15, making the downward movement of the hollow rod 13 smoother, ensuring the stability of the synchronous downward movement of the squeeze plug, and contributing to the smooth operation of the repair fluid spraying process.

[0026] like Figures 1 to 9 As shown, in a specific embodiment, both the second squeeze plug 134 and the third squeeze plug 135 are provided with drain ports 136. One end of each drain port 136 is connected to the inner cavity of the hollow rod 13, and the other end is connected to the upper liquid storage cavity 122 and the lower liquid storage cavity 123, respectively. The hollow rod 13 is also provided with an inlet port 131, which is connected to the inner cavity of the storage roller 1. The liquid in the storage roller 1 enters the hollow rod 13 through the inlet port 131 and is input into the upper liquid storage cavity 122 and the lower liquid storage cavity 123 through the drain ports 136. When the hollow rod 3 moves down, the inlet port 131 is covered and sealed by the sliding cover 132 installed on the sleeve 12, and the two drain ports 136 slide inside the corresponding positioning blocks 121 to seal, ensuring the sealing of the upper liquid storage cavity 122 and the lower liquid storage cavity 123. This structure enables automatic replenishment of the repair fluid while ensuring the sealing of the storage chamber during spraying to prevent leakage and ensure that the repair fluid can be accurately discharged from the spray nozzle 124, thereby improving the utilization efficiency of the repair fluid.

[0027] like Figures 1 to 9As shown, a synchronization plate 14 is further installed on the side wall of the hollow rod 13. Limiting rods 141 are movably installed through both ends of the synchronization plate 14. The bottom of the limiting rods 141 is installed in the inner cavity of the storage roller 1, and a limiting plate 142 is installed on the top of the limiting rods 141. The diameter of the limiting plate 142 is larger than the diameter of the limiting rod 141, and the limiting plate 142 is used to prevent the synchronization plate 14 from separating from the limiting rods 141. A limiting spring 143 is sleeved on the limiting rod 141, and the limiting spring 143 is always in a compressed state. One end of the limiting spring 143 is engaged with the bottom of the synchronization plate 14, and the other end of the limiting spring 143 is engaged with the inner wall of the storage roller 1. The elastic force of the limiting spring 143 is used to push the hollow rod 13 to fit against the surface of the positioning shaft 15. The coordination of the synchronization plate 14, the limit rod 141, and the limit spring 143 enables the hollow rod 13 to automatically reset, preparing for the next squeezing spray, ensuring the continuity of the operation, reducing manual operation, and improving the efficiency of the operation. Example

[0028] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, several pairs of retainers 211 are installed on the inner wall of the storage roller 1, and the retainers 211 are positioned on both sides of the corresponding insert sleeve 12. A stirring plate 2 is rotatably mounted on the retainer 211. A pressure arm 21 is installed at one end of the stirring plate 2, and one end of the pressure arm 21 is slidably connected to the synchronous plate 14. When the synchronous plate 14 moves down, it squeezes the pressure arm 21 to rotate, thereby driving the stirring plate 2 to deflect and stir the repair fluid. A retaining shaft 213 is installed at the center of rotation of the pressure arm 21. Both ends of the retaining shaft 213 are rotatably connected to the retainer 211. A torsion spring 212 is sleeved on the retaining shaft 213. One end of the torsion spring 212 is engaged with the retainer 211, and the other end of the torsion spring 212 is engaged with the side wall of the stirring plate 2. The setting of the stirring plate 2 can stir the repair fluid, prevent it from settling and ensuring that the concentration of the repair fluid is uniform. The synchronous plate 14 drives the movement of the pressure arm 21 to realize the automation of stirring, without the need for additional power, thus saving energy.

[0029] like Figures 1 to 9 As shown in the specific embodiment, a side plate 222 is installed on the side wall of the synchronization plate 14, and a slide rod 22 is installed on the side plate 222. A strip groove 221 is opened on the pressure arm 21, and the slide rod 22 is slidably disposed inside the strip groove 221. The cooperation between the slide rod 22 and the strip groove 221 ensures that the pressure arm 21 can be smoothly driven to rotate when the synchronization plate 14 moves down, thereby enabling the stirring plate 2 to work normally, ensuring the stable progress of the stirring process, and further ensuring the uniformity of the repair fluid.

[0030] The implementation principle of the efficient soil remediation device for gardens according to the present invention is as follows: This invention utilizes the relative motion created by the rotation of the storage roller 1 and the fixed state of the positioning shaft 15 to achieve precise spraying of the repair fluid through the coordinated linkage of mechanical structures. Before operation, the device is connected to the tractor's rear bracket via the insert shaft 114 on the connecting frame 113. One end of the fixed shaft 11 is fixed to the positioning shaft 15, and the other end is connected to the storage roller 1 via the connecting seat 111 and the arched bracket 112, ensuring that the positioning shaft 15 remains stationary during operation, while the storage roller 1 can move with the tractor and rotate around the fixed shaft 11. At this time, the repair fluid is injected through the injection port 16 of the storage roller 1 and sealed with the sealing plug 161. Due to the chamfered design at the end and the weight of the device, the insert sleeve 12 naturally inserts into the soil under the tractor's traction. The outer side of the insert sleeve 12 penetrates deeper into the soil, while the inner side is relatively close to the surface, laying the foundation for the stratified delivery of the repair fluid. This structural design not only ensures a stable connection between the device and the tractor but also achieves the prerequisite for stratified spraying of the repair fluid through the depth difference of the insert sleeve. At the same time, the sealing structure ensures the effective storage of the repair fluid before operation.

[0031] During operation, the tractor drives the device forward, and the storage roller 1 rotates around the fixed shaft 11 as it moves, while the positioning shaft 15 remains stationary. This relative motion causes the protrusion 151 at the bottom of the positioning shaft 15 to periodically contact and squeeze the synchronous seat 153 at the top of the hollow rod 13 (the ball bearings 152 on the synchronous seat 153 fit against the end face of the positioning shaft 15 to reduce frictional resistance). When the hollow rod 13 moves down, it synchronously drives the first extrusion plug 133, the second extrusion plug 134 and the third extrusion plug 135 to slide in the positioning block 121, forming a direct extrusion on the upper liquid storage chamber 122 and the lower liquid storage chamber 123 separated by the positioning block 121 inside the insert 12. Because the diameters of the first squeeze plug 133, the second squeeze plug 134, and the third squeeze plug 135 decrease sequentially, and the diameter difference between the second squeeze plug 134 and the third squeeze plug 135 is greater, the squeezing force on the lower liquid storage chamber 123 is greater than that on the upper liquid storage chamber 122. This results in the spray nozzle 124 (corresponding to the deep soil layer) near the outer side of the sleeve 12 discharging more remediation fluid than the inner spray nozzle 124 (corresponding to the surface soil layer). This can specifically meet the remediation needs of deep soil layers. This quantitative distribution achieved through mechanical structural differences requires no additional power control and can accurately match the remediation needs of different soil depths, improving both the utilization efficiency of the remediation fluid and the applicability of the device.

[0032] During the extrusion spraying process, the sliding cover 132 on the insert 12 moves down with the hollow rod 13 to cover the inlet 131, while the drain port 136 slides and seals within the positioning block 121, ensuring that the repair fluid in the storage chamber is discharged only from the spray port 124 to avoid leakage. As the storage roller 1 continues to rotate, after the protrusion 151 of the positioning shaft 15 disengages from the synchronous seat 153, the limiting spring 143 at the bottom of the synchronous plate 14 (which is always in a compressed state) pushes the synchronous plate 14 to move up along the limiting rod 141, causing the hollow rod 13 and each extrusion plug to reset. At this time, the inlet 131 reopens, and the repair fluid in the storage roller 1 enters the inner cavity of the hollow rod 13 through the inlet 131, and then flows into the upper storage chamber 122 and the lower storage chamber 123 through the drain port 136, respectively, to replenish the repair fluid and prepare for the next extrusion spraying. This automatic sealing and resetting fluid replenishment mechanism ensures the continuity and stability of the spraying process, reduces manual intervention, and avoids waste and pollution of the repair fluid.

[0033] Furthermore, when the hollow rod 13 moves up and down, the synchronous plate 14 drives the sliding rod 22 to slide within the strip groove 221 of the pressure arm 21 via the side plate 222, causing the pressure arm 21 to rotate around the retaining shaft 213. This, in turn, causes the stirring plate 2 to deflect within the storage roller 1, stirring the repair fluid and preventing sedimentation. When the synchronous plate 14 moves upward, the torsion spring 212 on the retaining shaft 213 drives the stirring plate 2 to reset, ensuring uniform concentration of the repair fluid. The entire process relies on the relative motion formed by the rotation of the storage roller 1 and the fixation of the positioning shaft 15. Through the synergistic action of various structures, the repair fluid is sprayed in layers with quantitative precision, automatically replenished, and stirred to prevent sedimentation, efficiently completing the restoration of garden soil. The linkage design between the stirring mechanism and the main operation ensures the uniformity of the repair fluid without adding extra power, further improving the restoration effect and the overall efficiency of the device.
