Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a device for treating soil acidification using a variety of substances. Background Technology

[0002] Soil acidification refers to the process by which soil absorptive complexes absorb a certain amount of exchangeable hydrogen or aluminum ions, leading to the leaching of alkaline (basic) ions from the soil. Lime can be applied to adjust acidity and supplement calcium.

[0003] A known authorized patent application with application number CN202320513642.6 discloses an experimental device for soil acidification improvement. Its background art addresses the problem that "in practical use, lime is mostly sprinkled on the ground when added to the soil, which cannot guarantee even distribution, resulting in poor improvement effect." To address this, the proposed solution includes: "a mixing assembly comprising a plate, a shell fixedly connected to the surface of the plate, a bearing fixedly connected inside the shell, a first rotating rod rotatably connected inside the bearing, the first rotating rod movably penetrating and extending to the outside of the shell, and multiple mixing rods fixedly connected to the surface of the first rotating rod."

[0004] However, the following problems were found in the implementation of the above technical solutions: Although the provided technical solutions achieved the effect of uniform powder spreading, lime powder has now been proven to accelerate the release of metals in acidic soils. Calcite powder is now commonly used for soil improvement treatment. Moreover, the above structure is not convenient for adjusting the discharge amount of calcite powder. The volume of the hopper is fixed, which can easily lead to too much or too little calcite powder discharge when dealing with different types of soil or degrees of acidification, thereby reducing the effectiveness and flexibility of soil treatment. In addition, the above solutions are not convenient for crushing lumpy calcite powder, which can easily affect the discharge of calcite powder. Utility Model Content

[0005] This invention proposes a device for treating soil acidification using multiple substances, which solves the problems in related technologies where lime powder has been proven to accelerate the release of metals in acidic soils, and where the existing structure is not convenient for adjusting the discharge of calcite powder and for crushing agglomerated calcite powder.

[0006] The technical solution of this utility model is as follows: a device for treating soil acidification using multiple substances, comprising: a trolley and a hopper fixedly installed on its top, wherein the trolley is provided with a material discharge port;

[0007] A connecting pipe fixedly installed at the bottom of the hopper;

[0008] A feed housing fixedly installed at the bottom of the connecting pipe;

[0009] A motor that is fixedly installed on one end face of the feed housing and whose output end moves through the feed housing;

[0010] A feed impeller fixedly connected to one output end of the motor;

[0011] An electric push rod that is fixedly installed on the other end face of the feeding shell and whose output end moves through the feeding shell;

[0012] And a circular block rotatably connected to the output end of the electric push rod, wherein one end face of the circular block is provided with a clearance groove adapted to the feeding impeller.

[0013] Preferably, the interior of the hopper is equipped with a stirring and crushing mechanism for agitating and crushing the calcite powder.

[0014] The mixing and pulverizing mechanism includes a mounting plate fixedly installed on the top of the hopper, a rotating shaft rotatably connected to the mounting plate, a spiral blade fixedly installed on the bottom surface of the rotating shaft, two frame-type mixing blades symmetrically fixedly installed on the surface of the rotating shaft, multiple pulverizing rods rotatably connected between the inner walls of the frame-type mixing blades, and a second motor fixedly installed on the top of the mounting plate. The output end of the second motor moves through the mounting plate and is connected to the rotating shaft. The spiral blade is located inside the connecting pipe.

[0015] Preferably, the top of the trolley is provided with a spreading mechanism for spreading calcite powder.

[0016] The laying mechanism includes a toothed ring rotatably connected to the top of the trolley and corresponding to the material drop port, a T-shaped plate fixedly installed inside the toothed ring, a scraper fixedly installed at the bottom of the T-shaped plate, and a power component on the trolley for driving the toothed ring to rotate.

[0017] The power components include a third motor fixedly mounted on the top of the trolley via a base block, and a gear fixedly connected to the output end of the third motor and meshing with a gear ring.

[0018] Preferably, a spray pipe corresponding to the material discharge port is fixedly installed at the bottom of the trolley, a liquid storage tank is fixedly installed at the top of the trolley, a pump body is fixedly installed on one side of the liquid storage tank, and the output end of the pump body is connected to the spray pipe through a pipe passing through the trolley.

[0019] The working principle and beneficial effects of this utility model are as follows:

[0020] I. This utility model uses an electric push rod to move a circular block to the right, allowing the block to slide through the clearance groove and the feeding impeller, thus blocking the receiving space on the feeding impeller and reducing its carrying capacity. Conversely, by moving the circular block to the left using the electric push rod, the receiving space of the feeding impeller can be expanded. Therefore, this allows for easy adjustment of the calcite powder discharge amount according to the degree of soil acidification, avoiding excessive or insufficient calcite powder discharge. It facilitates adjustment for different types of soil, effectively improving the effectiveness and flexibility of soil remediation.

[0021] Second, this utility model uses a motor to drive the rotating shaft, frame-type stirring blade, and spiral blade to rotate, which facilitates the stirring of calcite powder by the frame-type stirring blade. At the same time, the crushing rod can break up the clumps of calcite powder, preventing the clumps from affecting the feeding. The rotation of the spiral blade ensures the smoothness and continuity of the calcite powder feeding, avoids blockage, and improves the efficiency of soil remediation. Attached Figure Description

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] Please see Figure 1 - Figure 5 The present invention provides a device for treating soil acidification using multiple substances, comprising: a trolley 1 and a hopper 2 fixedly installed on its top, the trolley 1 having a material discharge port, wherein the trolley 1 is equipped with a controller for controlling the electrical components in the device;

[0032] The connecting pipe 3 is fixedly installed at the bottom of the hopper 2;

[0033] The material discharge shell 4 is fixedly installed at the bottom of the connecting pipe 3. The material discharge shell 4 is made of transparent material and has scales on its surface.

[0034] A motor 5 is fixedly installed on one end face of the feeding shell 4 and its output end moves through the feeding shell 4;

[0035] The feeding impeller 6 is fixedly connected to the output end of the motor 5. The outer surface of the feeding impeller 6 is adapted to the inner wall of the feeding shell 4 to prevent material jamming.

[0036] An electric push rod 7 is fixedly installed on the other end face of the feeding shell 4 and its output end moves through the feeding shell 4;

[0037] And a circular block 8 rotatably connected to the output end of the electric push rod 7. One end face of the circular block 8 is provided with a clearance groove that is compatible with the feeding impeller 6. The outer surface of the circular block 8 is compatible with the inner wall of the feeding shell 4, which can avoid the phenomenon of material jamming.

[0038] The technical solution provided in this embodiment is as follows: During use, the trolley 1 is moved to the operating position, and an external power supply is connected to the device. Simultaneously, personnel use testing instruments to test the soil. Then, calcite powder (or stone powder, fly ash, mineral phosphate powder, etc.) is added to the hopper 2. Motor 5 drives the feeding impeller 6 and the circular block 8 to rotate, aligning the receiving space on the feeding impeller 6 with the connecting pipe 3, allowing the calcite powder to fall from the connecting pipe 3 into the receiving space on the feeding impeller 6. After a certain period, motor 5 drives the feeding impeller 6 to rotate, aligning the receiving spaces in other positions with the connecting pipe 3 for reloading, and discharging the calcite powder through the discharge port on the feeding shell 4. This allows the calcite powder to pass through the discharge port. When the calcite powder is discharged onto the soil surface for treatment, and the discharge rate needs to be adjusted based on the test data, the electric push rod 7 moves the circular block 8 to the right. This causes the circular block 8 to slide through the clearance groove and the discharge impeller 6, blocking the receiving space on the discharge impeller 6 and reducing its carrying capacity. Conversely, moving the circular block 8 to the left with the electric push rod 7 expands the receiving space of the discharge impeller 6. This allows for easy adjustment of the calcite powder discharge rate according to the degree of soil acidification, avoiding excessive or insufficient discharge. It also facilitates adjustment for different types of soil, effectively improving the effectiveness and flexibility of soil treatment.

[0039] Furthermore, the interior of hopper 2 is equipped with a stirring and crushing mechanism for agitating and crushing calcite powder.

[0040] The mixing and crushing mechanism includes a mounting plate 9 fixedly installed on the top of the hopper 2, a rotating shaft 10 rotatably connected to the mounting plate 9, a spiral blade 11 fixedly installed on the bottom surface of the rotating shaft 10, two frame-type stirring blades 12 symmetrically fixedly installed on the surface of the rotating shaft 10, multiple crushing rods 13 rotatably connected between the inner walls of the frame-type stirring blades 12, and a second motor 14 fixedly installed on the top of the mounting plate 9. The output end of the second motor 14 moves through the mounting plate 9 and is connected to the rotating shaft 10. The spiral blade 11 is located inside the connecting pipe 3.

[0041] Specifically, after calcite powder is added to hopper 2, motor 214 drives shaft 10 to rotate, which in turn drives frame-type stirring blades 12 and spiral blades 11 to rotate. The frame-type stirring blades 12 stir the calcite powder, and during this stirring process, the calcite powder passes between the crushing rods 13, causing the crushing rods 13 to rotate and break up any clumps of calcite powder, preventing clumps from clogging the connecting pipe 3 during discharge. The spiral blades 11 also rotate, causing the calcite powder to tumble upwards, which, combined with the frame-type stirring blades 12, facilitates thorough stirring and crushing of the calcite powder. After stirring for a period of time, motor 214 drives shaft 10 to reverse direction, allowing the spiral blades 11 to transport the calcite powder through the connecting pipe 3 to the discharge shell 4 for discharge, ensuring smooth and continuous calcite powder discharge.

[0042] Furthermore, the top of the cart 1 is equipped with a spreading mechanism for spreading calcite powder.

[0043] The laying mechanism includes a toothed ring 15 rotatably connected to the top of the trolley 1 and corresponding to the material drop port, a T-shaped plate 16 fixedly installed inside the toothed ring 15, a scraper 17 fixedly installed at the bottom of the T-shaped plate 16, and a power component provided on the trolley 1 for driving the toothed ring 15 to rotate.

[0044] The power components include a motor 18 fixedly mounted on the top of the trolley 1 via a base block, and a gear 19 fixedly connected to the output end of the motor 18 and meshing with the gear ring 15.

[0045] Specifically, after the calcite powder falls onto the soil, the motor 18 drives the gear 19 to rotate, and the gear 19 drives the gear ring 15 to rotate, thereby causing the T-shaped plate 16 to drive the scraper 17 to rotate, so that the scraper 17 can come into contact with the calcite powder on the soil, thus achieving the effect of evenly spreading the calcite powder.

[0046] Furthermore, a nozzle 20 corresponding to the material discharge port is fixedly installed at the bottom of the cart 1, and a liquid storage tank 21 is fixedly installed at the top of the cart 1. A pump body 22 is fixedly installed on one side of the liquid storage tank 21. The output end of the pump body 22 is connected to the nozzle 20 through a pipe passing through the cart 1. Multiple nozzles are installed on the surface of the nozzle 20. An injection pipe is installed at the top of the liquid storage tank 21. The input end of the pump body 22 extends into the interior of the liquid storage tank 21 through a pipe.

[0047] Specifically, when treating soil acidification, the soil conditioner is injected into the storage tank 21, and then pumped by the pump body 22 and transported through the pipeline to the spray nozzle 20 for spraying onto the soil. This allows the conditioner and calcite powder to be used together for further treatment and improvement of the soil, thereby achieving the purpose of treatment with multiple substances and improving the treatment effect. Alternatively, the conditioner and calcite powder can be used separately as needed.

[0048] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
