Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil turning device. Background Technology

[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. Fundamentally, the technical principles of contaminated soil remediation can include changing the form in which pollutants exist in the soil or how they bind to the soil, reducing their mobility and bioavailability in the environment, and reducing the concentration of harmful substances in the soil.

[0003] Currently, existing devices have relatively simple structures and mostly repair soil by spraying remediation agents. During the spraying process, the liquid covers the soil surface and does not easily penetrate into the soil. The soil and liquid are not mixed evenly, and the liquid on the soil surface is easy to evaporate, which reduces the remediation effect of the liquid and is therefore not conducive to improving the efficiency of soil remediation. Utility Model Content

[0004] In view of this, the present invention aims to provide a soil turning device to improve the efficiency of soil remediation.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A soil turning device,

[0007] Compared with the prior art, this utility model has the following advantages:

[0008] The soil turning device described in this utility model, through the setting of the mounting base, allows the drill bit to be raised and lowered, enabling the turning of soil at different depths. Connecting the water pipe between the drill bit and the storage tank allows the remediation liquid to flow out through the through holes and mix with the soil when the turning blades turn the soil, thus penetrating into the soil and improving the remediation effect of the remediation liquid, thereby improving the soil remediation efficiency.

[0009] Secondly, the design of the first and second grooves provides a clear movement path for the sliding of the mounting base, preventing it from shifting during movement. Simultaneously, it reduces vibration of the mounting base when the drill bit turns over the soil, thus improving its stability. The drive shaft and motor allow the mounting base to move the drill bit up and down, facilitating soil turning at different depths. Furthermore, the lifting and lowering process of the mounting base remains smooth, enhancing the overall stability of the device.

[0010] Furthermore, the use of sliding columns and grooves not only ensures the stability of the mounting base's sliding motion but also distributes some of the load, reducing the burden on the drive shaft and extending its service life, thus lowering maintenance costs. By incorporating a first sleeve, a second sleeve, and a transmission assembly, the first sleeve can be driven to rotate via the drive component, and the second sleeve via the transmission assembly. This allows the drill bit to rotate at different heights, improving the overall quality of soil turning and facilitating thorough mixing of the soil and remediation solution.

[0011] The water pipe passes through the first and second sleeves in sequence, which protect the water pipe from rupture when the soil is turned over, preventing leakage of the remediation solution and affecting the mixing of the soil and the remediation solution. The connecting grooves connect the water pipe to each through hole, which facilitates the full mixing of the remediation solution with the soil when it is turned over, thereby improving the efficiency of soil remediation.

[0012] Furthermore, the meshing connection between the first and second gears ensures smooth transmission between the first and second sleeves, allowing them to rotate synchronously and drive the drill bit. The structure is simple and easy to design and implement. The protective shell protects the first and second gears, preventing soil from adhering to them during soil turning and damaging them, thus ensuring the normal operation of the device.

[0013] The protective cover prevents personnel from colliding with the exposed drill bit, thus avoiding injury. The roller brush cleans the drill bit, preventing soil from corroding it and extending its lifespan, thereby reducing equipment maintenance costs. The telescopic rod and pressure plate flatten the soil turned over by the drill bit, eliminating the need for personnel to manually flatten the soil after turning it over, improving work efficiency and reducing the workload of operators.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] This embodiment relates to a soil turning device that can fully mix soil and remediation solution, thereby improving soil remediation efficiency.

[0032] In terms of overall structure, combined Figures 1 to 4 As shown, the soil turning device of this embodiment includes a body 1, a mounting base 2 slidably mounted on the body 1, a drill bit 3 rotatably connected to the mounting base 2 and extending along the length of the body 1, and a water pipe 4 connected to the drill bit 3, with the other end of the water pipe 4 connected to a storage tank 11 for storing remediation fluid mounted on the body 1. Furthermore, the drill bit 3 is provided with spiral-shaped turning blades 31 and multiple through holes 32 communicating with the water pipe 4.

[0033] At this time, as set up above, the drill bit 3 can be raised and lowered by the mounting base 2, which can turn over soil at different depths. The water pipe 4 is connected between the drill bit 3 and the liquid storage tank 11. When the turning blade 31 turns over the soil, the repair liquid can flow out through each through hole 32 and mix with the soil, penetrate into the soil, improve the repair effect of the repair liquid, and thus help improve the soil repair efficiency.

[0034] It is worth mentioning that the water pipe 4 and the drill bit 3 can be connected via an existing rotary joint. In practice, the remediation fluid in the storage tank 11 can flow into the drill bit 3 through the water pipe 4, causing the mounting base 2 to lower the drill bit 3 to below the soil surface. The drill bit 3 is then driven to rotate, and its rotating blades agitate the soil, allowing the remediation fluid to be discharged from multiple through holes 32 and fully mixed with the soil. This improves the remediation effect of the remediation fluid, thereby increasing the soil remediation efficiency.

[0035] In the specific structure, the drill bit 3 is provided with three sets of through holes 32 arranged along its own axial spacing. Each set of through holes 32 includes four through holes 32 arranged along the circumferential spacing of the drill bit 3. Of course, the number of sets of through holes 32 in this embodiment can be designed and adjusted according to actual needs. For example, it can be set to one set, two sets, four sets, etc. In addition, the number of through holes 32 in each set can also be designed and adjusted according to actual needs. For example, it can be set to one, two, or five, etc.

[0036] It is worth mentioning that the water pipe 4 in this embodiment can be a plastic soft water pipe in the prior art, such as a rubber soft water pipe, a PVC (Polyvinyl chloride) hose, a PVC corrugated pipe, etc.

[0037] Based on the above overall introduction, in this embodiment, as a preferred implementation, such as Figure 1 and Figure 3 As shown, the body 1 includes a base frame 12, and a first bracket 13 and a second bracket 14 arranged at intervals along the width direction of the body 1 on the base frame 12. The first bracket 13 and the second bracket 14 are respectively provided with a first groove 131 and a second groove 141 extending along the height direction of the body 1. The two ends of the mounting base 2 in the length direction slide in the first groove 131 and the second groove 141 respectively.

[0038] Here, the first groove 131 and the second groove 141 provide a clear movement path for the sliding of the mounting base 2, preventing the mounting base 2 from shifting during movement. Simultaneously, they reduce the vibration of the mounting base 2 when the drill bit 3 turns over the soil, thereby improving the stability of the mounting base 2. Furthermore, in this embodiment, the liquid storage tank 11 is located on top of the first support 13 and the second support 14.

[0039] Specifically, in this embodiment, as a preferred implementation, such as Figure 3 and Figure 4 As shown, a drive shaft 132 is rotatably mounted on the first groove 131. The drive shaft 132 extends along the height direction of the body 1, and a motor 133 is mounted on the first groove 131. The motor 133 is used to drive the drive shaft 132 to rotate, which enables the mounting base 2 to slide up and down.

[0040] Therefore, by setting up the drive shaft 132 and the motor 133, the mounting base 2 can be driven to move the drill bit 3 up and down, which is convenient for turning over the soil at different depths. At the same time, it can also keep the lifting process of the mounting base 2 stable and improve the overall stability of the device.

[0041] In specific implementation, the drive shaft 132 of this embodiment is provided with threads. The drive shaft 132 is driven to rotate by the motor 133. Under the drive of the threads, the mounting base 2 can drive the drill bit 3 to move up and down, so as to turn over the soil at different depths and make the soil and remediation liquid fully mixed.

[0042] Furthermore, in this embodiment, as a preferred implementation, it is still as follows: Figure 3 and Figure 4 As shown, the second groove 141 is provided with a sliding column 142 extending along the height direction of the body 1, and the mounting seat 2 is provided with a sliding groove 21 adapted to the sliding column 142 at one end near the second groove 141. The mounting seat 2 slides on the sliding column 142 through the sliding groove 21.

[0043] Here, by setting the sliding column 142 and the sliding groove 21, the stability of the sliding of the mounting base 2 can be further guaranteed, while also sharing part of the load and reducing the burden on the drive shaft 132, thereby extending the service life of the drive shaft 132 and helping to reduce maintenance costs.

[0044] Furthermore, in this embodiment, as a preferred implementation, such as Figure 2 and Figure 4 As shown, the mounting base 2 is provided with a first sleeve 22 extending along the height direction of the machine body 1, and a driving component 23 for driving the first sleeve 22 to rotate. The drill bit 3 is provided with a second sleeve 24 extending along the length direction of the machine body 1, and a transmission component 25 is provided between the first sleeve 22 and the second sleeve 24.

[0045] By setting up the first sleeve 22, the second sleeve 24 and the transmission assembly 25, the first sleeve 22 can be driven to rotate by the drive component 23 and the second sleeve 24 can be rotated by the transmission assembly 25. Thus, the drill bit 3 can rotate at different heights, thereby improving the overall quality of soil turning and facilitating the full mixing of soil and remediation liquid.

[0046] It should be noted that the driving component 23 in this embodiment can be a driving product well known to those skilled in the art, such as motor 133. In the specific structure, both the driving component 23 and the first sleeve 22 are provided with gears. Through the meshing between the two gears, the first sleeve 22 is rotated, and under the action of the transmission component 25, the second sleeve 24 is driven to rotate, thereby realizing the rotation of the drill bit 3.

[0047] It should be noted that the transmission component 25 in this embodiment can be configured using existing structures, such as gear transmission, worm gear transmission, etc. This embodiment preferably uses gear transmission.

[0048] Furthermore, it should be noted that in this embodiment, as a preferred implementation, such as Figure 4As shown, the end of the water pipe 4 away from the liquid storage tank 11 passes through the first sleeve 22 and the second sleeve 24 in sequence and is connected to the drill bit 3. The drill bit 3 is provided with a connecting groove 33 extending along its own axis. The connecting groove 33 is used to connect the water pipe 4 with each through hole 32.

[0049] The advantage of this arrangement is that the water pipe 4 passes through the first sleeve 22 and the second sleeve 24 in sequence, which can protect the water pipe 4 and prevent it from breaking when the soil is turned over, thus preventing the remediation fluid from leaking out and affecting the mixing of the soil and the remediation fluid. Furthermore, by setting up the connecting groove 33, the water pipe 4 can be connected to each through hole 32, which facilitates the full combination of the remediation fluid and the soil when the soil is turned over, thereby improving the efficiency of soil remediation.

[0050] Furthermore, in this embodiment, as a preferred implementation, we continue to refer to... Figure 4 As shown, the transmission assembly 25 includes a first gear 251 sleeved on the first sleeve 22 and a second gear 252 sleeved on the second sleeve 24, and the first gear 251 and the second gear 252 mesh with each other.

[0051] Here, the meshing connection between the first gear 251 and the second gear 252 ensures smooth transmission between the first sleeve 22 and the second sleeve 24, enabling the first sleeve 22 and the second sleeve 24 to rotate synchronously, thereby driving the drill bit 3 to rotate. The structure is simple and easy to design and implement.

[0052] Considering the normal operation of the device, in this embodiment, as a preferred implementation, such as... Figure 2 As shown, a protective shell 221 is fitted onto the first sleeve 22, and the first gear 251 and the second gear 252 are both located inside the protective shell 221.

[0053] Here, by providing a protective shell 221, the first gear 251 and the second gear 252 can be protected. When turning over the soil, soil adhesion to the first gear 251 and the second gear 252 can be prevented, thus avoiding damage to the first gear 251 and the second gear 252 and affecting the transmission between them, thereby ensuring the normal operation of the device. It should be understood that in other embodiments, it is also possible to fit the protective shell 221 onto the second sleeve 24.

[0054] In the specific structure, the first sleeve 22 and the second sleeve 24 in this embodiment are rotatably connected to the protective shell 221, and the protective shell 221 is shaped as a bent tube. Of course, in addition to being shaped as a bent tube, it can also be shaped as other common shapes.

[0055] In addition, in this embodiment, as a preferred implementation, as shown in the figure, the base frame 12 is provided with a protective cover 51 corresponding to the drill bit 3. Inside the protective cover 51 is a roller brush 521, which is used to clean residual soil from the drill bit 3. Here, the protective cover 51 prevents personnel from bumping into the exposed drill bit 3 and causing personal injury. Simultaneously, the roller brush 521 cleans the drill bit 3, preventing soil adhering to it from corroding it, thereby extending the service life of the drill bit 3 and reducing the maintenance cost of the device.

[0056] In the specific structure, the inner wall of the protective cover 51 is provided with a mounting bracket 52, the roller brush 521 rotates on the mounting bracket 52, and the end of the roller brush 521 near the head of the drill bit 3 is inclined downward, so as to facilitate cleaning of the drill bit 3.

[0057] In addition, in this embodiment, as a preferred implementation, such as Figure 1 and Figure 3 As shown, the end of the machine body 1 away from the protective cover 51 is provided with a telescopic rod 15 extending along its own height direction. The driving end of the telescopic rod 15 is provided with a pressure plate 16, which is used to flatten the soil turned over by the drill bit 3.

[0058] Here, by setting up the telescopic rod 15 and the pressure plate 16, the soil turned over by the drill bit 3 can be flattened, avoiding the need for personnel to flatten the soil after it has been turned over, thereby improving work efficiency and reducing the labor intensity of the operators.

[0059] In practice, as the device moves forward, the drill bit 3 will turn over the soil, causing the turned-over soil to rise above the soil surface. At this time, the pressure plate 16 will slide up and down by driving the telescopic rod 15, thereby flattening the turned-over soil.

[0060] In this embodiment, the soil turning device drives the drill bit 3 to descend below the soil surface by driving the mounting base 2, and drives the drill bit 3 to rotate to turn the soil. The repair fluid is discharged through the through holes 32 on the drill bit 3, so that the soil and the repair fluid are fully mixed, thereby improving the repair effect of the repair fluid and improving the soil repair efficiency.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
