DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] Embodiment 1

[0037] like Figure 1-Figure 5 As shown, a farmland soil pollution control and restoration device proposed in Example 1 of the present application includes:

[0038] Support frame 1, a ground-inserting rod 101 is fixedly connected to the bottom of the support frame 1, and a support vertical pipe 102 is fixedly connected to the upper end of the support frame 1, wherein the ground-inserting rod 101 is used as a fixing member to firmly set up the support frame 1 on the ground. The length of the ground-inserting rod 101 can be changed according to the hardness of the soil. The softer the soil, the longer the length of the ground-inserting rod 101 is required;

[0039] The intermittent soil drilling member 2 comprises a cylindrical frame 201 fixedly connected to the top of the support vertical tube 102, a threaded ring 202 is rotatably installed in the cylindrical frame 201, a spliced ​​drill pipe 203 which slides through the cylindrical frame 201 and the support vertical tube 102 is installed through the threaded inner thread of the threaded ring 202, and a medicament tube 204 is detachably connected to the top of the spliced ​​drill pipe 203. It should be noted that the outer side of the spliced ​​drill pipe 203 is constructed with a sliding groove along its length direction, and the inner sides of the support vertical tube 102 and the cylindrical frame 201 are both constructed with convex strips which slide with the sliding groove to limit the rotation of the spliced ​​drill pipe 203, so as to ensure that the threaded ring 202 can drive the spliced ​​drill pipe 203 to move downward when rotating;

[0040] The driving member 3 includes an impeller 301 fixedly connected to the outside of the threaded ring 202 and located in the cylindrical frame 201. A pressure water pipe 302 is connected to one side of the cylindrical frame 201. The bottom of the cylindrical frame 201 is fixedly connected to a shunt pipe 303 arranged on the circumferential side of the spliced ​​drill pipe 203. The driving member 3 serves as a driving component of the intermittent soil drilling member 2, wherein the pressure water pipe 302 is connected to the existing water supply equipment. By controlling the intermittent supply of water flow, the impeller 301 can be intermittently rotated, thereby driving the spliced ​​drill pipe 203 to be gradually inserted into the deep soil layer. During the process of the spliced ​​drill pipe 203 intermittently going downward, the chemical pipe 204 can also continuously inject chemical into it. During the intermittent stop period, the chemical can fully cover the soil of each stage layer, thereby ensuring the uniform coverage of the chemical and ensuring the soil repair effect;

[0041] The water collecting sunshade 4 is fixedly connected to the cylindrical frame 201 and is used to collect rainwater and block sunlight. In hot sunny weather, it can reduce water loss and ensure the softness of the soil in this part, so that the spliced ​​drill pipe 203 can continue to go deep. In windy and rainy weather, it can receive rainwater as a counterweight to ensure the stability of the device and improve safety.

[0042] The device as a whole needs to be placed on the ground using a support frame 1, and then connected to the ground using a ground rod 101 to fix the device. After that, water can be injected into the cylindrical frame 201 through a pressure water pipe 302, and the impeller 301 is driven to rotate by the water flow. At the same time, the water flow will be sprayed toward the soil near the spliced ​​drill pipe 203 through the diversion pipe 303 to soften the soil in the area so that the spliced ​​drill pipe 203 can penetrate the soil smoothly. At the same time, the rotation of the impeller 301 will drive the threaded ring 202 to rotate, and produce a threaded fit with the spliced ​​drill pipe 203, so that the spliced ​​drill pipe 203 can continue to penetrate the soil. The entire process relies on the water flow control device for operation, and no electronic components are required for control, which reduces the risk of device failure, can adapt to most severe weather, ensure the safety of the device, and increase the service life of the device.

[0043] like Figure 4 As shown, in the first embodiment, the support frame 1 includes a frame plate 103, a support vertical pipe 102 is fixedly installed through the frame plate 103, a plurality of inclined support plates 104 are connected in an array on the circumferential side of the support vertical pipe 102, a nail rod 105 is movably installed through the bottom end of the inclined support plate 104, and a plurality of inclined grooves 106 are arrayed along the length direction of the nail rod 105, wherein the inclined support plate 104 serves as an auxiliary support member, which can make the connection between the support vertical pipe 102 and the frame plate 103 more stable, and the inclined groove 106 on the nail rod 105 is inclined upwardly arranged, and after the nail rod 105 is inserted into the soil, the soil will be filled therein by the extrusion force, thereby improving the stability of the nail rod 105 in the soil and further improving the stability of the device.

[0044] Embodiment 2

[0045] like Figure 7-Figure 8As shown, this embodiment further improves the present application on the basis of the first embodiment. Considering that the length of penetration into the soil needs to be adjusted according to the situation, in order to better improve the adaptability of the device, in the second embodiment, the spliced ​​drill pipe 203 includes a plurality of spliced ​​pipes 2031, wherein a threaded hole 2032 is configured at the bottom of one of the spliced ​​pipes 2031, and a plurality of injection holes 2033 arranged near the bottom of the spliced ​​pipe 2031 are configured on its circumferential side, a column block 2034 is connected to the inner thread of the threaded hole 2032, a conical plug 2035 is fixedly connected to the bottom of the column block 2034, a plug-in hole 2036 is configured at the top of the spliced ​​pipe 2031, and a plurality of L-shaped vertical grooves 2037 are configured on the inner wall of the plug-in hole 2036 along its circumferential array, and a plug-in column pipe 2038 connected to the plug-in hole 2036 is fixedly connected to one end of the drug tube 204 at the bottom of the other spliced ​​pipe 2031, and the plug-in column pipe 2038 connected to the plug-in hole 2036 is fixedly connected to the bottom of the other spliced ​​pipe 2031 and one end of the drug tube 204. The outer peripheral array structure of 038 is provided with a plurality of protrusions 2039 which are engaged with the L-shaped vertical groove 2037. The setting of the conical plug 2035 enables it to be inserted into the soil more easily. The setting of the injection hole 2033 on the circumferential side allows the spliced ​​drill pipe 203 to continuously inject medicine into the soil layer during the process of penetrating into the soil, thereby avoiding soil blockage and increasing safety. There are multiple spliced ​​tubes 2031, which are mainly used to extend the overall length after the end-to-end connection to adapt to soil repair operations at different depths and increase the flexibility of the device. Compared with the traditional connection method, the setting of the protrusion 2039 and the L-shaped vertical groove 2037 only requires the plug-in column tube 2038 to be inserted into the plug-in hole 2036 and then rotated to connect the two spliced ​​tubes 2031 together. The operation can be reversed when disassembling. The operation is more convenient and saves manpower.

[0046] Embodiment 3

[0047] like Figure 5-Figure 6 As shown, this embodiment further improves the present application on the basis of the second embodiment. Considering that the device needs to intermittently penetrate into the soil to ensure that the agent can fully penetrate into the soil, in the third embodiment, the pressure water pipe 302 includes a transverse pipe 3021 fixedly connected to the side of the cylindrical frame 201, and the other end of the transverse pipe 3021 is connected to a pressure storage member 3022 installed on the water collecting light shield 4, and a pressure valve 3023 for intermittently opening and closing the transverse pipe 3021 is installed in the transverse pipe 3021. It should be noted that the function of the pressure valve 3023 is that the pressure valve 3023 will only be opened when the water pressure in the water pipe reaches a certain level. When the pressure is insufficient, the pressure can be stored by the pressure storage member 3022, so as to achieve the effect of intermittent rotation of the impeller 301, so that the spliced ​​drill pipe 203 can stay in the soil layers of different depths for a certain period of time, so that the agent can be fully injected into each soil layer to ensure the repair effect.

[0048] like Figure 3 and Figure 6As shown, in the third embodiment, the pressure storage member 3022 includes a ring-shaped tube 5 fixedly connected to the water collecting light shield 4, one end of the ring-shaped tube 5 is connected to the transverse tube 3021, and the upper side of the ring-shaped tube 5 is connected to a plurality of squeeze bottles 6 fixed to the water collecting light shield 4 along its circumferential array. The pressure valve 3023 includes a rotating rod 30231 that rotates and passes through the transverse tube 3021, one end of the rotating rod 30231 is fixedly connected to a valve plate 30232 located in the transverse tube 3021, and a torsion spring 30233 is connected between the other end of the rotating rod 30231 and the outer wall of the transverse tube 3021. The elastic force of the torsion spring 30233 can be used as a force to prevent the valve plate 30232 from rotating. Only when the pressure stored in the pressure storage member 3022 is greater than the force of the torsion spring 30233, the valve plate 30232 will flip over to open the cross pipe 3021, so that it can intermittently provide water flow to the cylindrical frame 201. On the one hand, this water supply method is to allow the stored water sprayed onto the soil in the early stage to penetrate into the soil smoothly to avoid waste of water resources. On the other hand, it can make the spliced ​​drill pipe 203 stay in different soil layers for a certain period of time to ensure sufficient injection of the agent.

[0049] like Figure 3 As shown, in the third embodiment, the squeeze bottle 6 includes a bottle body 601, the upper end of the bottle body 601 is open and the end is configured with a retaining ring 602, a piston block 603 is slidably installed in the bottle body 601, and the squeeze bottle 6 has two structures, one of which is an integral plastic bottle that can shrink and deform, such as a beverage bottle. When the pressure valve 3023 closes the cross tube 3021, water will flow toward the squeeze bottle 6 for storage, and the height of the squeeze bottle 6 needs to be higher than the cylindrical frame 201. At this time, the potential pressure in the bottle body 601 is greater than the potential pressure of the cross tube 3021, and after continuous water flow injection, the cross tube 3021 and The pressure in the bottle body 601 will gradually exceed the elastic force of the torsion spring 30233 of the pressure valve 3023, thereby pushing the valve plate 30232 to flip and open the cross tube 3021. After the pressure is released, the pressure returns to a level less than the elastic force of the torsion spring 30233. At this time, the water flow in the bottle body 601 is lost and the bottle body 601 shrinks. Another structure is that the bottle body 601 has a piston block 603, and the up and down movement of the piston block 603 is used to control the water pressure in the bottle body 601. Compared with the deformation of the bottle body 601 itself, this structure is safer and can increase the service life of the device.

[0050] Embodiment 4

[0051] like Figure 5As shown, this embodiment further improves the present application on the basis of the third embodiment. Considering that the device will encounter greater resistance when penetrating into the soil, precise softening of the soil can reduce the resistance and better perform in-depth operations. In the fourth embodiment, the diversion pipe 303 includes an annular frame 3031 fixedly sleeved on the support vertical pipe 102, and a plurality of water spray pipes 3032 are connected along a circumferential array at the bottom of the annular frame 3031. A flow pipe 3033 connected to the bottom of the cylindrical frame 201 is fixedly connected to the top of the annular frame 3031. The water spray pipe 3032 can spray water on the soil near the spliced ​​drill pipe 203 to ensure that the water penetrates into the soil for softening. The water flow is diverted to the plurality of water spray pipes 3032 by the annular frame 3031, so that the water flow can penetrate more evenly around the spliced ​​drill pipe 203 to ensure the in-depth operation of the spliced ​​drill pipe 203.

[0052] like Figure 1 and Figure 3 As shown, in embodiment 4, the water-collecting sunshade 4 includes an arc-shaped half-frame 401 fixedly connected to the cylindrical frame 201 and opening downwardly arranged, the upper side of the arc-shaped half-frame 401 is connected to a water-collecting frame 402 opening upwardly arranged, and a plurality of over-pressure leakage pipes 403 arranged toward the ground are installed in the water-collecting frame 402. The arc-shaped half-frame 401 can block sunlight from more directions, so as to reduce moisture loss in the soil near the spliced ​​drill pipe 203 and ensure the softening degree, and the water-collecting frame 402 is used to collect rainwater on rainy days. On the one hand, it can be used as a counterweight to increase the safety of the device, and on the other hand, the over-pressure leakage pipe 403 can be used to gradually drip rainwater downwards, so that the rainwater assists the soil to flow through the hose, thereby increasing the functionality of the device.

[0053] like Figure 3 and Fig. 9 As shown, in the fourth embodiment, the overpressure leakage pipe 403 includes a conical frame 4031 fixedly connected to the bottom of the water collecting frame 402, the bottom of the conical frame 4031 is fixedly connected with a drip pipe 4032 that runs through the arc-shaped half frame 401, the top of the conical frame 4031 is constructed with a cross plate 4033, and the edge of the conical frame 4031 is fixedly connected with four elastic sheets 4034 that are in conflict with the cross plate 4033. When the rainwater storage reaches a certain level, the water pressure will pass through the elastic sheet 4034 over the conical frame 4031 and enter the drip pipe 4032, so as to achieve rapid water release. It should be noted that there is a gap between the elastic sheet 4034 and the cross plate 4033. When the water pressure is less than the elastic force of the elastic sheet 4034, the water will still flow, but the flow rate is small, which can also play a role in assisting in softening the soil for a long time.

[0054] like Figure 2 and Figure 4As shown, in Example 4, the number of water spray pipes 3032 and over-pressure leakage pipes 403 is the same, and a plurality of through grooves 1031 arranged opposite to the water spray pipes 3032 and the over-pressure leakage pipes 403 are constructed on the frame plate 103. A funnel plate 1032 is constructed at the upper end of the through groove 1031 and a water retaining plate 1033 is constructed at the lower end. It should be noted that the bottom openings of the water spray pipes 3032 and the over-pressure leakage pipes 403 are both facing the funnel plate 1032. The funnel plate 1032 can effectively receive and store water sources, and accurately inject it into the soil around the spliced ​​drill pipe 203 through the water retaining plate 1033, thereby reducing the scope of water diffusion and infiltration into the soil, thereby ensuring the softening efficiency of the area.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
