Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, specifically relating to a soil remediation agent dispensing device. Background Technology

[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. There are many methods of soil remediation, among which the application of remediation agents to the soil is one of them. When applying remediation agents, a special remediation agent application device is required.

[0003] However, most existing application devices require drilling holes in the soil to be repaired before the repair agent is applied into the holes. This requires drilling rigs and related tools, increasing equipment rental, maintenance and labor costs, and making the operation quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a soil remediation agent dispensing device that integrates drilling and dispensing into one unit, reducing the overall cost of the equipment, saving time from multiple operations, and improving remediation efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A soil remediation agent dispensing device includes a drill rod and a drill bit. The drill rod is hollow, and the drill bit is disposed at the bottom of the drill rod and communicates with it. A rotating rod is sleeved on the surface of the drill rod, and a soil-supporting mechanism is disposed inside the rotating rod. The soil-supporting mechanism includes: a rotating plate rotatably connected to the top of the drill rod and fixedly connected to the bottom of the inner wall of the rotating rod; four arc-shaped grooves, each formed at the top of the rotating plate and extending to the bottom of the rotating plate; four sliding blocks, each fixedly connected to the top of the drill bit and slidably connected to the inside of the arc-shaped grooves; limiting blocks, each fixedly connected to the top of the drill bit; and a guide plate connected to the bottom of the inner wall of the drill rod and located between the rotating plate and the drill bit, with the limiting blocks slidably connected to both sides of the guide plate.

[0007] Preferably, the drill bit is conical in shape and is composed of four arc-shaped segments joined together.

[0008] Preferably, a circular component is fixedly connected to the top of each sliding block, and the circular component is located on the top of the rotating plate.

[0009] Preferably, a toothed disc is fixedly connected to the top of the drill rod surface, and a toothed ring is fixedly connected to the top of the inner wall of the rotating rod, the toothed ring meshing with the toothed disc.

[0010] Preferably, a handle is fixedly connected to the top of the drill rod, and the top of the handle has a feeding port.

[0011] Preferably, an auxiliary bucket is fixedly connected to the inner wall of the dispensing port, and the auxiliary bucket is wider at the top and narrower at the bottom and is conical in shape.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, when soil remediation agents need to be applied, the drill bit is inserted into the soil by first holding the drill rod and rotating rod. Then, the rotating rod is rotated counterclockwise. The counterclockwise rotation of the rotating rod drives the rotating plate to rotate, which in turn squeezes the sliding block to slide along the arc-shaped groove. At the same time, the sliding block causes the drill bit to separate and move outward. As the drill bit moves outward, it also causes the limiting block to move smoothly outward along the direction of the guide plate. After the drill bit separates, its interior is hollow. As the drill bit moves outward, it can also clear the soil in the bottom hole. Then, the remediation agent is applied into the inside of the drill rod through the top application port. The remediation agent will move down the drill rod and fall onto the soil at the center hole of the drill bit. This design integrates drilling and application of remediation agents into one unit, which not only saves the total cost of equipment and labor, but also allows for precise application with the assistance of the drill rod, thereby improving the accuracy of the remediation.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a soil remediation agent dispensing device includes a drill rod 1 and a drill bit 101. The drill rod 1 is hollow, and the drill bit 101 is located at the bottom of the drill rod 1 and communicates with it. A rotating rod 2 is sleeved on the surface of the drill rod 1, and a soil-supporting mechanism is provided inside the rotating rod 2. The soil-supporting mechanism includes: a rotating plate 201, which is rotatably connected to the top of the drill rod 1 and fixedly connected to the bottom of the inner wall of the rotating rod 2; four arc-shaped grooves 202, each formed at the top of the rotating plate 201 and extending to the bottom of the rotating plate 201; four sliding blocks 203, each fixedly connected to the top of the drill bit 101 and slidably connected inside the arc-shaped grooves 202; and four limiting blocks 204, each fixedly connected to the top of the drill bit 101; and a guide. Plate 205 and guide plate 205 are connected to the bottom of the inner wall of drill rod 1 and located between rotating plate 201 and drill bit 101. Limiting block 204 is slidably connected to both sides of guide plate 205. With the cooperation of soil supporting mechanism, the soil around drill bit 101 can be pushed outward while drilling, so that drill bit 101 is hollow. Then, repair agent is put into the drill rod 1. The repair agent will fall into the soil between drill bit 101 along the drill rod 1, so as to realize continuous operation of drilling and application of repair agent, making the whole repair process more efficient and significantly improving work efficiency. At the same time, it reduces the complexity of operation steps and equipment. Operators do not need to switch between drilling and application of repair agent. Instead, they can complete two tasks at the same time with one device, simplifying the operation process and saving equipment purchase and maintenance costs.

[0022] like Figure 4 As shown, the drill bit 101 is conical in shape and is composed of four arc-shaped segments. The conical design of the drill bit 101 can effectively reduce the resistance during drilling, allowing the drill bit 101 to enter the soil more smoothly. At the same time, the four arc-shaped segments of the drill bit 101 can improve the overall stability of the drill bit 101. The splicing structure of the arc-shaped segments can effectively disperse the pressure generated during drilling and can evenly push the soil around the drill bit 101 outward, allowing the remediation agent to be applied to a larger area, thus enabling the remediation of a larger area of ​​soil.

[0023] like Figure 4As shown, a circular component 3 is fixedly connected to the top of the sliding block 203. The circular component 3 is located on the top of the rotating plate 201. The circular component 3 can limit the sliding block 203 inside the arc groove 202, preventing the sliding block 203 from shifting when sliding inside the arc groove 202, and at the same time preventing the sliding block 203 and the drill bit 101 from moving down and affecting the normal use of the soil supporting mechanism.

[0024] like Figure 3 As shown, a geared disc 401 is fixedly connected to the top of the surface of the drill rod 1, and a geared ring 402 is fixedly connected to the top of the inner wall of the rotating rod 2. The geared ring 402 meshes with the geared disc 401. The meshing connection between the geared disc 401 and the geared ring 402 can achieve stable rotational transmission through interaction. When the rotating rod 2 rotates, it can drive the geared ring 402 to mesh and rotate around the geared disc 401, which can ensure the stability during the rotation process.

[0025] like Figures 1-2 As shown, a handle 501 is fixedly connected to the top of the drill rod 1. The top of the handle 501 has an insertion port 502. The design of the handle 501 provides a stable gripping position for the operator when drilling, making the operation more comfortable and effortless. Moreover, through the handle 501, the operator can better control the direction, depth and force of the drill rod 1, improving the stability of the drilling operation.

[0026] like Figures 1-2 As shown, the inner wall of the inlet 502 is fixedly connected to the auxiliary hopper 6. The auxiliary hopper 6 is wide at the top and narrow at the bottom and is conical in shape. The conical auxiliary hopper 6 effectively controls the flow path of the repair agent through the design of being wide at the top and narrow at the bottom, avoiding leakage or overflow of the repair agent during operation. This design can reduce the waste of the repair agent and maximize the utilization rate of the repair agent.

[0027] The working principle of this utility model is as follows: When it is necessary to apply a remediation agent to the soil for remediation, the drill bit 101 can be inserted into the soil by first holding the drill rod 1 and the rotating rod 2. Then, the rotating rod 2 is rotated counterclockwise. The counterclockwise rotation of the rotating rod 2 can drive the rotating plate 201 to rotate. The rotation of the rotating plate 201 will squeeze the sliding block 203 to slide along the arc groove 202. At the same time, the sliding block 203 can drive the drill bit 101 to separate and move to one end. As the drill bit 101 moves to one end, it can drive the limiting block 204 to move along the guide plate 205. While moving smoothly outwards, the drill bit 101 separates and its interior is hollow. As the drill bit 101 moves outwards, it can clear away the soil in the bottom hole. Then, the remediation agent is placed inside the drill rod 1 through the top inlet 502. The remediation agent will move down the drill rod 1 and fall onto the soil at the center hole of the drill bit 101. This design integrates drilling and remediation agent placement, which not only saves the total cost of equipment and labor, but also allows for precise placement with the assistance and guidance of the drill rod 1, thereby improving the accuracy of the remediation.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
