Description

Technical Field

[0001] This utility model relates to the technical field of soil impurity removal devices, and in particular to a soil quick-drying impurity removal device for soil testing. Background Technology

[0002] In the field of soil testing, efficient purification and rapid drying of soil samples are crucial for ensuring the accuracy and reliability of test results. Soil testing covers a wide range of areas, including soil composition analysis, fertility assessment, and pollution detection. Before conducting these tests, it is necessary to obtain clean and dry soil samples to avoid interference from impurities and moisture. Therefore, developing a rapid drying and purification device that meets the needs of soil testing is of paramount practical significance. It directly affects the efficiency and quality of soil testing work, and consequently impacts decision-making in various fields such as agricultural production guidance and environmental monitoring.

[0003] In existing soil impurity removal and drying technologies, common impurity removal methods mainly rely on simple manual sieving or the use of some relatively simple mechanical sieving equipment. Manual sieving depends on workers manually operating the screen and constantly shaking it to separate soil particles from impurities. This method is entirely manpower-intensive and inefficient. Some traditional mechanical sieving equipment usually uses a motor to drive the screen to make simple reciprocating linear or circular motions. The movement of soil on the screen is relatively simple and it is difficult to achieve effective separation of particles of different sizes from impurities. In terms of drying technology, most methods adopt natural air drying or sun drying. Natural air drying is greatly affected by environmental factors, takes a long time, and cannot guarantee that the soil sample will not be contaminated during the drying process.

[0004] However, existing technologies have a significant problem: low efficiency and poor results in impurity removal. Traditional impurity removal methods, whether manual sieving or simple mechanical sieving, cannot quickly and thoroughly remove impurities from the soil. Due to the wide variety and size of impurities in soil samples, simple sieving is insufficient to fully separate impurities from the soil, resulting in a large amount of impurities remaining. This not only affects the accuracy of subsequent test results but also damages the testing equipment, seriously impacting work efficiency and failing to meet the needs of modern soil testing for speed and efficiency. Therefore, a soil quick-drying impurity removal device for soil testing is proposed to solve the above problems. Utility Model Content

A ball is slidably connected to the bottom of each movable column, and the outer wall of the ball is slidably connected to the outer wall of the concave-convex ring.

The bottom of the drive motor is fixedly connected to the top of the base plate, and the output end of the drive motor is fixedly connected to the bottom of the rotating disk.

[0011] As a further description of the above technical solution:

[0012] The drying assembly includes a drying chamber, the outer wall of which is fixedly connected to a discharge ramp and a control console. The discharge ramp is located above the screening assembly.

[0013] As a further description of the above technical solution:

[0014] The screening assembly includes a vibrating box, the bottom of which is fixedly connected to the top of the movable column, and a guardrail is provided on the outer wall of the vibrating box, the bottom of which is fixedly connected to the top of the support plate.

[0015] As a further description of the above technical solution:

[0016] The vibrating box has a slidably connected screening tray and a carrying tray inside, with the screening tray located above the carrying tray. Both the screening tray and the carrying tray have handles fixedly connected to their side walls.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the drive motor drives the rotating disk to rotate, and the wave-shaped concave and convex ring on the top of the rotating disk rotates accordingly. The concave and convex ring pushes the movable column up and down by the rolling ball, which drives the fixed plate to repeatedly compress the buffer spring, so that the vibrating box will continuously bounce up and down. The soil is vibrated, the impurities are left in the screening tray, and the fine soil falls into the carrying tray, achieving the effect of rapid impurity removal. This solves the problems of low efficiency and poor effect of traditional impurity removal, and improves the efficiency and quality of impurity removal.

[0025] 2. In this utility model, the operator manually slides the linkage handle inward. The displacement of the linkage handle causes the limit plate to move, so that the locking column is disengaged from the vibrating box. The limit spring is then compressed. At this time, the operator can pull the bearing tray by the handle to take out the bearing tray and the screening tray, which achieves the effect of quickly taking soil and cleaning impurities. This solves the problem of the previous cumbersome and time-consuming operation of taking soil and cleaning impurities, and improves work efficiency. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a soil quick-drying and impurity removal device for soil testing, comprising a base plate 1, which serves as a supporting foundation for the entire device and supports components such as a screening component, a drying component, and a vibration component. The top of the base plate 1 is provided with a screening component and a drying component. The drying component is used to heat and dry the soil to remove moisture from the soil for subsequent screening operations. The drying component is located on the side of the screening component, which is used to screen the dried soil and separate impurities. The vibration component is provided below the screening component, and a support plate 2 is provided between the screening component and the vibration component. The support plate 2 is made of aluminum alloy and serves to separate the screening component and the vibration component and provide support for the screening component.

[0035] The vibration assembly includes a rotating disk 10, which is made of aluminum alloy and has good wear resistance and stability. A concave-convex ring 11 is fixedly connected to the top of the rotating disk 10. The concave-convex ring 11 is made of the same material as the rotating disk 10 and has a wave-like shape. Its function is to cause the movable columns 15 to move up and down through its own rotation, thereby driving the screening assembly to vibrate. A support assembly and a power assembly are arranged below the rotating disk 10 to ensure its stability during rotation. The power assembly is located in the middle of the support assembly and provides power for the rotation of the rotating disk 10. Multiple movable columns 15 are arranged above the concave-convex ring 11. The movable columns 15 are made of stainless steel and their function is... The rotational motion of the concave-convex ring 11 is converted into vertical linear motion and transmitted to the screening assembly. The top of each movable column 15 is fixedly connected to the bottom of the screening assembly by bolts, and the bottom of each movable column 15 is fixedly connected to a fixed plate 17 by welding. Each movable column 15 is fitted with a buffer spring 16, which acts as a buffer when the movable column 15 moves up and down, reducing the impact and wear between components. One end of each buffer spring 16 is fixedly connected to the bottom of the support plate 2, and the other end is fixedly connected to the outer wall of the fixed plate 17. Each movable column 15 has a ball bearing 14 slidably connected to its bottom. When the concave-convex ring 11 rotates, the ball bearing 14 moves on its surface. The rolling motion causes the movable column 15 to move up and down. The outer wall of the ball 14 is slidably connected to the outer wall of the concave-convex ring 11. The support assembly includes multiple fixed columns 13, which are distributed circumferentially below the rotating disk 10. The bottom of the rotating disk 10 has a groove 12. The bottom of each fixed column 13 is fixedly connected to the top of the base plate 1, and the top of each fixed column 13 is slidably connected to a ball 14. The outer wall of each ball 14 is slidably connected to the inside of the groove 12. The function of the fixed columns 13 and the ball 14 is to support the rotating disk 10 and ensure that the rotating disk 10 can rotate smoothly. The power assembly includes a drive motor 9, the bottom of which is fixedly connected to the top of the base plate 1. The output end of the drive motor 9 is fixedly connected to the top of the base plate 1. The drying assembly includes a drying box 5, which is fixedly connected to the bottom of the rotating disk 10. The outer wall of the drying box 5 is fixedly connected to a discharge ramp 6 and a control console 7. The discharge ramp 6 is located above the screening assembly. Multiple support rods 8 are fixedly connected to the bottom of both the drying box 5 and the support plate 2. Their function is to support the drying box 5 and the support plate 2 and ensure their stability. The bottom of each support rod 8 is fixedly connected to the top of the base plate 1. The screening assembly includes a vibrating box 4, which is made of metal. Its function is to accommodate the screening tray 18 and the carrying tray 19 for screening the soil. The bottom of the vibrating box 4 is fixedly connected to the top of the movable column 15. A guardrail 3 is provided on the outer wall of the vibrating box 4. The bottom of the guardrail 3 is fixedly connected to the top of the support plate 2.

[0036] Specifically, when using this soil quick-drying and impurity removal device for soil testing, the operator first places the soil to be tested in the drying chamber 5. The heating element inside the drying chamber 5 generates heat after being powered on, heating and drying the soil to remove moisture. The dried soil slides down the discharge slope 6 and is discharged into the screening tray 18 inside the vibrating chamber 4. At this time, the operator starts the drive motor 9 via the control panel 7. The output of the drive motor 9 drives the rotating disk 10 to rotate. Supported by the fixed column 13 and the rolling balls 14, the rotating disk 10 rotates in a circular motion. The rotation of the rotating disk 10 causes the concave-convex ring 11 at its top and the sliding groove 12 at its bottom to rotate synchronously. The rotation of the concave-convex ring 11 and the sliding groove 12 causes the multiple rolling balls 14 above and below to slide. The lower rolling ball 14 is located at the top of the fixed column 13 and slides inside the sliding groove 12. Since the bottom of the fixed column 13 is fixed to the top of the base plate 1, the rolling balls 14 slide within the sliding groove 12. The inner sliding support supports the rotating disk 10, ensuring that the rotating disk 10 can rotate smoothly. At the same time, the rolling of the ball 14 reduces the friction between the rotating disk 10 and the fixed column 13. The upper concave-convex ring 11 is wavy. When the concave-convex ring 11 rotates, the ball 14 at the bottom of the inner side of the movable column 15 rolls on the outer wall of the concave-convex ring 11. Due to the wavy shape of the concave-convex ring 11, the ball 14 moves up and down with the undulation of the concave-convex ring 11 during the rolling process. When the ball 14 is at the crest of the concave-convex ring 11, the movable column 15 is in a higher position. When the ball 14 is at the trough of the concave-convex ring 11, the movable column 15 is in a lower position. Therefore, as the concave-convex ring 11 rotates, the rolling of the ball 14 causes the movable column 15 to move up and down repeatedly. The repeated displacement of the movable column 15 also drives the fixed plate 17 to move synchronously. Since the fixed plate 17 is fixedly connected to the bottom of the movable column 15, when the movable column 15 moves up and down, the fixed plate 17 also moves up and down accordingly. The displacement of the fixed plate 17 causes the buffer spring 16 to be repeatedly compressed and stretched. The elasticity of the buffer spring 16 plays a role in buffering and shock absorption, reducing the impact force between the movable column 15 and the support plate 2. At the same time, since the bottom of the vibrating box 4 is fixedly connected to the top of the movable column 15, the up and down movement of the movable column 15 is directly transmitted to the vibrating box 4, causing the vibrating box 4 to move up and down as well. The up and down movement of the vibrating box 4 causes the soil placed in the screening tray 18 to be subjected to vibration force. Under the action of vibration force, larger impurities cannot pass through the screen holes of the screening tray 18 due to their own weight and shape, and remain on the surface of the screening tray 18. Soil particles, on the other hand, pass through the screen holes of the screening tray 18 and fall into the bearing tray 19 below, thus completing the soil impurity removal work and achieving a fast and efficient impurity removal effect. When it is necessary to stop the screening operation, the operator turns off the drive motor 9 through the control panel 7, the rotating disk 10 stops rotating, and the movable column 15 and the vibrating box 4 also stop moving.

[0037] Reference Figure 4 and Figure 5 Inside the vibrating chamber 4, a screening tray 18 and a support tray 19 are slidably connected via a sliding fit structure. The screening tray 18 is located above the support tray 19 and is made of a metal plate with sieve holes. The function of the screening tray 18 is to screen the soil, allowing smaller soil particles to fall through the sieve holes into the support tray 19, while larger impurities remain on the surface of the screening tray 18. The support tray 19 is used to collect the soil that has passed through the sieve holes of the screening tray 18. Handles 20 are fixedly connected to the side walls of both the screening tray 18 and the support tray 19, allowing workers to easily pull them out of the vibrating chamber 4. Locking posts 21 are slidably connected to the left and right sides of the interior of both the screening tray 18 and the support tray 19. The function of the locking posts 21 is to fix the screening tray 18 and the support tray 19 inside the vibrating chamber 4 during the screening process, preventing them from shaking or falling out during vibration. The outer wall of one side of the locking posts 21 is slidably connected to the interior of the vibrating chamber 4. Limiting plates 22 are fixedly connected to the side walls of the locking pins 21. The function of the limiting plates 22 is to limit the sliding range of the locking pins 21 and prevent them from coming out of the screening tray 18 and the carrying tray 19. The limiting plates 22 are slidably connected inside the screening tray 18 and the carrying tray 19. A linkage handle 23 is fixedly connected to the outer wall of the limiting plates 22. Its function is to provide an operating interface for the operator. The limiting plates 22 and the locking pins 21 are moved by sliding the linkage handle 23. Limiting springs 24 are provided on the side of the limiting plates 22. The function of the limiting springs 24 is to provide an outward elastic force when the locking pins 21 are inserted into the vibrating box 4, so that the locking pins 21 are stably fixed inside the vibrating box 4. When it is necessary to remove the screening tray 18 and the carrying tray 19, the limiting springs 24 are compressed and store elastic potential energy. One end of the limiting springs 24 is fixedly connected to the side wall of the limiting plates 22, and the other end of the limiting springs 24 is fixedly connected to the inside of the screening tray 18 and the carrying tray 19.

[0038] Specifically, after the soil impurity removal is completed, the worker holds the linkage handle 23 and applies a pushing force towards the inside of the screening tray 18 and the carrying tray 19, sliding the linkage handle 23. Since the linkage handle 23 is fixedly connected to the limiting plate 22, when the linkage handle 23 moves, it will directly pull the limiting plate 22. The limiting plate 22 moves linearly along the same direction as the linkage handle 23 on the sliding track inside the screening tray 18 and the carrying tray 19. Because the locking pin 21 is fixedly connected to the limiting plate 22, the movement of the limiting plate 22 will drive the locking pin 21 to move synchronously. The locking pin 21, which was originally inserted into the vibrating box 4, moves linearly from its position inside the vibrating box 4 into the screening tray 18 and the carrying tray 19 under the action of the limiting plate 22, and finally detaches from the inside of the vibrating box 4. At the same time, when the limiting plate 22 moves inward, the limiting spring 24 is gradually compressed, and the elastic potential energy continuously increases. At this time, the worker holds the carrying tray 19 with his hand. The handle 20 on the side wall applies a pulling force to the outside of the vibrating box 4. Under the pulling force applied by the worker, the carrying tray 19 moves in a straight line from the inside of the vibrating box 4 to the outside of the vibrating box 4 along the sliding track inside the vibrating box 4 until it is completely removed from the vibrating box 4. The worker can then pour out the soil after impurity removal from the carrying tray 19. Similarly, the worker holds the handle 20 on the side wall of the screening tray 18 and applies a pulling force to the outside of the vibrating box 4. The screening tray 18 moves in a straight line from the inside of the vibrating box 4 along the sliding track inside the vibrating box 4 and is removed from the vibrating box 4. Then, the impurities remaining inside the screening tray 18 are cleaned, thereby achieving the effect of quickly removing soil and cleaning impurities. When the screening tray 18 and the carrying tray 19 need to be used again, they are pushed back into the vibrating box 4. Under the restoring force of the limit spring 24, the locking pin 21 is inserted back into the vibrating box 4 to complete the fixation.

[0039] Working Principle: When using this soil quick-drying and impurity removal device for soil testing, the operator first places the soil in the drying chamber 5 for heating and drying. The dried soil is then discharged through the discharge ramp 6 into the screening tray 18 inside the vibrating chamber 4. At this time, the operator starts the drive motor 9 via the control console 7. The drive motor 9 drives the rotating disk 10 to rotate. The rotation of the rotating disk 10 causes the concave-convex ring 11 at the top and the sliding groove 12 at the bottom to rotate synchronously. The rotation of the concave-convex ring 11 and the sliding groove 12 causes multiple rolling balls 14 above and below to slide. The lower rolling balls 14 are located inside the fixed column 13, which supports the rotating disk 10. The upper concave-convex ring 11 is wavy, which causes the moving column 15 to move up and down repeatedly through the rolling balls 14. The repeated displacement of the moving column 15 also drives the fixed plate 17 to move synchronously. The movement of the movable column 15 causes the buffer spring 16 to be repeatedly compressed, and the displacement of the movable column 15 also causes the entire vibrating box 4 to repeatedly bounce up and down, which in turn causes the soil to be subjected to vibration force. Larger impurities remain on the surface of the screening tray 18, while the soil falls into the carrying tray 19, thus completing the soil impurity removal work and achieving a fast and efficient impurity removal effect. After the soil impurity removal work is completed, the operator manually slides the linkage handle 23 inward. The displacement of the linkage handle 23 causes the limit plate 22 to move accordingly, which in turn causes the locking column 21 to move and disengage from the inside of the vibrating box 4. At the same time, the limit spring 24 is compressed. At this time, the operator can pull the carrying tray 19 with the handle 20 to take out the soil after impurity removal. Similarly, the screening tray 18 can also be taken out to clean the impurities inside, thus achieving the effect of quickly taking out the soil and cleaning the impurities.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
