Description

Technical Field

[0001] This application relates to the field of soil remediation, and in particular to a chemical injection device for soil remediation engineering. Background Technology

[0002] Soil remediation engineering refers to engineering activities that use physical, chemical, or biological technologies to treat and restore polluted or degraded soil in order to improve soil quality and restore soil ecological functions. Its purpose is to remove pollutants from the soil, reduce the risk of soil pollution, and improve soil fertility and productivity, thereby ensuring ecological environment safety and sustainable agricultural development.

[0003] In soil remediation projects, in order to improve the soil environment, it is often necessary to inject specific agents into the soil. The traditional method of agent injection is to directly insert the agent tube into the soil and then inject the agent through the agent tube.

[0004] However, when the agent tube is directly inserted into the soil, it may encounter resistance, making it difficult for the agent tube to reach the ideal depth, thus affecting the distribution effect of the agent in the soil and reducing the effect of soil remediation. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that the agent tube may encounter resistance when directly entering the soil, making it difficult for the agent tube to reach the ideal depth, thereby affecting the distribution effect of the agent in the soil and reducing the effect of soil remediation. This application provides an agent injection device for soil remediation engineering.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A chemical injection device for soil remediation includes an injection box, a handle fixed to the injection box, a chemical tank fixed inside the injection box, a chemical tube fixed to the chemical tank, an injection pump fixed inside the chemical tank, an auxiliary mechanism between the injection box and the chemical tube, a positioning mechanism on the injection box, and a battery fixed inside the injection box.

[0008] By adopting the above technical solution, the auxiliary mechanism is used to send the pesticide tube into the soil, and then the pesticide in the pesticide tube is injected into the soil through the auxiliary mechanism. This makes it easier for the pesticide tube to enter the soil and reduces the possibility that the pesticide tube does not enter the soil deeply enough.

[0009] Furthermore, the auxiliary mechanism includes a drill rod mounted on the injection box, a drill bit fixed to the end of the drill rod away from the injection box, an injection hole opened on the drill bit, an auger fixed to both the drill rod and the drill bit, and a drive assembly disposed between the drill rod and the injection box.

[0010] By adopting the above technical solution, the drill rod and drill bit are allowed to penetrate deep into the soil, and then the chemical in the chemical tube is allowed to enter the soil through the injection hole of the drill bit. This makes it easier for the chemical tube to enter the soil and reduces the possibility that the chemical tube may not penetrate deep enough into the soil.

[0011] Furthermore, the drive assembly includes a support ring rotatably connected to the injection tank, the reagent tube passing through the support ring, the support ring being fixedly connected to the drill pipe, and a gear being fixed on the support ring.

[0012] By adopting the above technical solution, the gear drives the support ring to rotate, and the support ring drives the drill rod to rotate, which makes it easier for the drill rod and drill bit to drill into the soil.

[0013] Furthermore, a support frame is fixed on the injection box, a drive motor is fixed on the support frame, and a second gear is fixed on the output end of the drive motor, with the first gear meshing with the second gear.

[0014] By adopting the above technical solution, the drive motor drives gear two to rotate, gear two drives gear one to rotate, thereby making it easy for gear one to drive the support ring to rotate.

[0015] Furthermore, the positioning mechanism includes a positioning disk disposed on one side of the drill bit, the positioning disk being provided with a positioning rod one, a positioning rod two being slidably connected to the positioning rod one, the end of the positioning rod two away from the positioning rod one being fixedly connected to the injection box, a limit component being provided between the positioning rod one and the positioning rod two, and a support component being provided on the positioning rod one.

[0016] By adopting the above technical solution, the positioning plate is made to contact the ground, and the injection box is moved along the directions of positioning rod one and positioning rod two, thereby reducing the possibility of the drill rod and drill bit deviating during the drilling process.

[0017] Furthermore, the support assembly includes a support block fixed on the first positioning rod, the support block being located at the end of the first positioning rod near the injection box, and a support spring being sleeved on the second positioning rod, the two ends of which are fixedly connected to the support block and the injection box.

[0018] By adopting the above technical solution, the positioning rod one and positioning rod two are supported by the support spring on the support block, so that positioning rod one can extend from positioning rod two when the positioning plate is not in contact with the ground.

[0019] Furthermore, the limiting component includes a limiting block fixed on the second positioning rod. The limiting block is located at the end of the second positioning rod close to the first positioning rod. The first positioning rod has a limiting groove, and the limiting block is located in the limiting groove and is slidably connected to the first positioning rod.

[0020] By adopting the above technical solution, when positioning rod one and positioning rod two are in an extended state, the limiting block abuts against the inner wall of the limiting groove, thereby allowing positioning rod one and positioning rod two to remain in an extended state.

[0021] Furthermore, the positioning disk is provided with a positioning pin, which is located on the side of the positioning disk away from the positioning rod.

[0022] By adopting the above technical solution, when the positioning disc touches the ground, the positioning pin on the positioning disc is inserted into the ground, thereby further improving the stability of the positioning disc when it touches the ground.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application utilizes a drive motor to rotate gear two, which in turn rotates gear one, which in turn rotates a support ring. The support ring then drives the drill rod to drill a hole, which in turn drives the drill bit to rotate. The drill rod and drill bit together drive the auger to rotate. Under the rotation of the auger, the drill bit and drill rod enter the soil. After the drill bit has drilled to a suitable depth, the injection pump delivers the pesticide into the pesticide tube, which then enters the injection hole of the drill bit. This allows the pesticide to enter the soil more easily, reducing the possibility of insufficient depth of the pesticide tube in the soil.

[0025] 2. In this application, after the drill bit is brought into contact with the ground, the positioning pin on the positioning plate is inserted into the ground. When the drill bit and drill rod enter the soil, the injection box approaches the ground. The injection box drives the second positioning rod, allowing the second positioning rod to slide on the first positioning rod. At the same time, the limiting block on the second positioning rod slides in the limiting groove. Simultaneously, the injection box compresses the support spring on the support block, allowing the first and second positioning rods to support the injection box. When the drill bit and drill rod are pulled out of the soil, the support spring pushes the first and second support rods to return to their original positions. At the same time, the limiting block prevents the second support rod from detaching from the first support rod, thus achieving the purpose of reducing the possibility of the drill rod and drill bit deviating during the drilling process.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a reagent injection device for soil remediation engineering.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A chemical injection device for soil remediation includes an injection box 1, a handle 2 fixed on the injection box 1, a chemical tank 3 fixed in the injection box 1, a chemical tube 4 fixed on the chemical tank 3, a chemical injection pump 8 fixed in the chemical tank 3, an auxiliary mechanism 6 between the injection box 1 and the chemical tube 4, a positioning mechanism 5 on the injection box 1, and a battery 7 fixed in the injection box 1.

[0035] When using this agent injection device, first inject the agent into the agent tank 3 through the injection port on one side of the injection tank 1. Then, hold the handle 2 and move the injection tank 1 to the required position. Next, place the auxiliary mechanism 6 and positioning mechanism 5 on the injection tank 1 onto the ground. The positioning mechanism 5 provides positioning support for the auxiliary mechanism 6. Then, use the auxiliary mechanism 6 to send the agent tube 4 into the soil. Then, use the injection pump 8 to send the agent from the agent tank 3 into the agent tube 4. Then, the agent from the agent tube 4 enters the auxiliary mechanism 6 and then enters the soil from the auxiliary mechanism 6, completing the agent injection work. By using the auxiliary mechanism 6 to send the agent tube 4 into the soil, and then letting the agent in the agent tube 4 be injected into the soil through the auxiliary mechanism 6, the agent tube 4 can enter the soil more easily, reducing the possibility that the agent tube 4 does not enter the soil deeply enough.

[0036] Reference Figure 2 , Figure 3 and Figure 4The auxiliary mechanism 6 includes a drill rod 61 mounted on the injection box 1. A drill bit 62 is fixed to one end of the drill rod 61 away from the injection box 1. An injection hole is provided on the drill bit 62. A screw conveyor 63 is fixed to both the drill rod 61 and the drill bit 62. A drive assembly 64 is provided between the drill rod 61 and the injection box 1.

[0037] In addition, the drive assembly 64 includes a support ring 641 rotatably connected to the injection box 1, a reagent tube 4 passing through the support ring 641, the support ring 641 being fixedly connected to the drill rod 61, and a gear 642 being fixed on the support ring 641.

[0038] Furthermore, a support frame 644 is fixed on the injection box 1, a drive motor 645 is fixed on the support frame 644, and a gear 643 is fixed on the output end of the drive motor 645. Gear 642 meshes with gear 643.

[0039] First, the drill bit 62 is placed against the ground. Then, the drive motor 645 drives the gear 2 643 to rotate, which in turn drives the gear 1 642 to rotate. The gear 1 642 then drives the support ring 641 to rotate, which in turn drives the drill rod 61 to drill a hole. The drill rod 61 drives the drill bit 62 to rotate, and the drill rod 61 and drill bit 62 together drive the auger 63 to rotate. The rotation of the auger 63 allows the drill bit 62 and drill rod 61 to enter the soil. After the drill bit 62 has drilled to a suitable depth, the injection pump 8 delivers the pesticide into the pesticide pipe 4, which then enters the injection hole of the drill bit 62, allowing the pesticide to enter the soil. When necessary... When the drill rod 61 and drill bit 62 are pulled out, the drive motor 645 drives the gear 2 643 to reverse, which in turn drives the gear 1 642, which in turn drives the support ring 641 to rotate in the opposite direction. This causes the drill rod 61 and drill bit 62 to rotate in the opposite direction. Under the action of the auger, the drill rod 61 and drill bit 62 are pulled out of the soil. The drill rod 61 and drill bit 62 are then driven into the soil by the auger 63. The chemical tube 4 follows the drill rod 61 and drill bit 62 into the soil, allowing the chemical to be injected into the soil through the chemical hole of the drill bit 62. This makes it easier for the chemical tube 4 to enter the soil and reduces the possibility that the chemical tube 4 may not reach the required depth.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The positioning mechanism 5 includes a positioning disk 51 disposed on one side of the drill bit 62. The positioning disk 51 is provided with a positioning rod 52. A positioning rod 53 is slidably connected to the positioning rod 52. The end of the positioning rod 53 away from the positioning rod 52 is fixedly connected to the injection box 1. A limit component 55 is provided between the positioning rod 52 and the positioning rod 53. A support component 54 is provided on the positioning rod 52.

[0041] In addition, the support assembly 54 includes a support block 541 fixed on the positioning rod 52. The support block 541 is located at the end of the positioning rod 52 near the injection box 1. A support spring 542 is sleeved on the positioning rod 53. Both ends of the support spring 542 are fixedly connected to the support block 541 and the injection box 1.

[0042] Furthermore, the limiting component 55 includes a limiting block 551 fixed on the second positioning rod 53. The limiting block 551 is located at one end of the second positioning rod 53 near the first positioning rod 52. The first positioning rod 52 has a limiting groove 552. The limiting block 551 is located in the limiting groove 552 and is slidably connected to the first positioning rod 52.

[0043] Furthermore, the positioning disk 51 is provided with a positioning pin 56, which is located on the side of the positioning disk 51 away from the positioning rod 52.

[0044] After the drill bit 62 is brought into contact with the ground, the positioning pin 56 on the positioning plate 51 is inserted into the ground. When the drill bit 62 and the drill rod 61 enter the soil, the injection box 1 approaches the ground. The injection box 1 drives the second positioning rod 53, allowing the second positioning rod 53 to slide on the first positioning rod 52. At the same time, the limiting block 551 on the second positioning rod 53 slides in the limiting groove 552. Simultaneously, the injection box 1 compresses the support spring 542 on the support block 541, allowing the first positioning rod 52 and the second positioning rod 53 to support the injection box 1. When the drill bit 62 and the drill rod 61 are pulled out of the soil, the support spring 542 pushes the first support rod and the second support rod to return to their original positions. At the same time, the limiting block 551 prevents the second support rod from detaching from the first support rod. By inserting the positioning pin 56 on the positioning plate 51 into the ground and then moving the injection box 1 along the first and second support rods, the possibility of the drill rod 61 and the drill bit 62 deviating during the drilling process can be reduced.

[0045] Working principle: When using this drug injection device, first inject the drug into the drug tank 3 through the injection port on one side of the injection tank 1. Then, hold the handle 2 and move the injection tank 1 to the desired position. Then, insert the positioning pin 56 on the positioning plate 51 into the ground, so that the positioning plate 51 touches the ground. Then, press down the handle 2 to make the injection tank 1 drive the drill rod 61 and the drill bit 62, so that the drill bit 62 touches the ground. Then, the drive motor 645 drives the gear 2 643 to rotate, the gear 2 643 drives the gear 1 642 to rotate, the gear 1 642 drives the support ring 641 to rotate, the support ring 641 drives the drill rod 61 to drill a hole, and the drill rod 61 drives the drill bit 62 to rotate. The drill rod 61 and drill bit 62 drive the auger 63 to rotate. Under the rotation of the auger 63, the drill bit 62 and drill rod 61 enter the soil. At the same time, the injection box 1 drives the positioning rod 2 53 to slide on the positioning rod 1 52. Simultaneously, the limiting block 551 on the positioning rod 2 53 slides in the limiting groove 552. At the same time, the injection box 1 squeezes the support spring 542 on the support block 541, so that the positioning rod 1 52 and positioning rod 2 53 support the injection box 1. After the drill bit 62 drills to a suitable depth, the injection pump 8 sends the agent into the agent tube 4, and then from the agent tube 4 into the injection hole of the drill bit 62, so that the agent enters the soil from the injection hole.
