Technical Field

[0001] This utility model belongs to the field of soil testing technology, specifically a soil analysis device for soil testing. Background Technology

[0002] Soil serves as the fundamental carrier for agricultural production, ecological environment, and geological research. The accurate detection of its physical and chemical properties, nutrient content, and pollution status is of great significance for sustainable agricultural development, environmental protection, and land resource management. With global population growth, arable land degradation, and intensifying environmental pollution problems, the demand for soil quality monitoring and assessment is becoming increasingly urgent, driving the rapid development of soil analysis technologies and related equipment.

[0003] In existing technologies, traditional soil analysis devices mostly rely on manual screening before pretreatment. Manual screening is time-consuming and labor-intensive, and after a long period of labor, uneven screening and missed screening may occur, which in turn leads to a decrease in soil screening efficiency, affects the analysis results, and increases labor costs.

[0004] Therefore, this utility model provides a soil analysis device for soil testing. Utility Model Content

The screening plate has screening grooves inside, and the screening plates are arranged at equal intervals inside the main housing. The diameter of the screening grooves decreases layer by layer. Through the above structure, the connecting block enables the screening plate to move back and forth quickly, so that the soil can be quickly screened and filtered after being added to the screening plate, which improves the screening efficiency of the device. At the same time, the use of screening grooves of different sizes enables multi-layer screening, which improves the particle uniformity of the soil during testing, reduces the influence of soil impurities on the test results, and improves the stability and practicality of the device.

[0011] Preferably, the outer wall of the limiting block and the inner wall of the limiting frame are both coated with a friction-reducing coating. Through the above structure, coating the outer wall of the limiting block and the inner wall of the limiting frame with a friction-reducing coating prevents the limiting block and the limiting frame from being worn by friction after long-term use, reduces maintenance costs, and improves the durability of the device.

[0012] Preferably, the screening plate is made of lightweight stainless steel. Through the above structure, the screening plate is made of lightweight stainless steel, so that the screening plate will not be corroded and worn after long-term soil screening, thus extending the service life of the screening plate, reducing maintenance costs, and improving the corrosion resistance and adaptability of the device.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 3 As shown in the embodiment of this utility model, a soil analysis device for soil testing includes a main housing 1. A feed hopper 101 is fixedly connected to the upper surface of the main housing 1. A first fixing block 11 is fixedly connected to the outer wall of the main housing 1. A motor 12 is fixedly connected to the upper surface of the first fixing block 11. A polarization shaft 13 is fixedly connected to the output end of the motor 12. The outer wall of the polarization shaft 13 is rotatably connected to the interior of a second fixing block 14. A vibration block 15 is slidably connected to the outer wall of the second fixing block 14. A connecting shaft 16 is fixedly connected to the outer wall of the vibration block 15. During operation, after soil is added from the feed hopper 101 into the main housing 1, the operator can start the motor 12. The motor 12 drives the polarization shaft 13 to rotate. 3. When rotating, the vibrating block 15 is driven to reciprocate. When the vibrating block 15 moves, it drives the connecting shaft 16 to move, which in turn causes the connecting shaft 16 to reciprocate rapidly. The main housing 1, the first fixing block 11, and the second fixing block 14 play the role of overall support and fixation. Through the above structure, the structural characteristics of the polarization shaft 13 are used to enable the vibrating block 15 to reciprocate rapidly, so that the soil can be filtered in multiple layers at the same time after being added into the device. This improves the efficiency of soil pretreatment before analysis and the efficiency of impurity screening. Compared with traditional manual screening, it reduces the labor intensity of workers, saves the downtime caused by screening, and improves the stability and practicality of the device.

[0026] like Figure 1 and Figure 3As shown, a connecting block 161 is rotatably connected inside the connecting shaft 16, and a screening plate 2 is fixed to the outer wall of the connecting block 161. Screening grooves 201 are formed inside the screening plate 2. The screening plates 2 are arranged at equal intervals inside the main housing 1, and the diameter of the screening grooves 201 decreases layer by layer. During operation, when the connecting shaft 16 moves, it drives the connecting block 161 to move, which in turn drives the screening plate 2 to move, causing the screening plate 2 to move rapidly back and forth. This allows the soil to be screened through the screening grooves 201, improving the uniformity of soil particles. The main housing 1 provides overall support and fixation. Through this structure, the connecting block 161 enables the screening plate 2 to move rapidly back and forth, allowing the soil to be quickly screened and filtered after being added to the screening plate 2, thus improving the screening efficiency of the device. Simultaneously, the use of screening grooves 201 of different sizes achieves multi-layer screening, improving the uniformity of soil particles during testing, reducing the impact of soil impurities on the test results, and enhancing the stability and practicality of the device.

[0027] like Figures 3 to 4 As shown, a limiting block 21 is fixedly connected to the upper surface of the screening plate 2, and a limiting frame 22 is fixedly connected to the inner wall of the main housing 1. The outer wall of the limiting block 21 is slidably connected to the inner wall of the limiting frame 22, and the outer wall of the screening plate 2 is slidably connected to the inner wall of the main housing 1. A hopper 102 is fixedly connected to the inner wall of the main housing 1. During operation, when the screening plate 2 moves, it will drive the limiting block 21 to move. When the limiting block 21 moves, its outer wall will slide on the inner wall of the limiting frame 22, so that the screening plate 2 remains stable when moving. The screening plate 2 and the main housing 1 play a role in overall support and fixation, and the hopper 102 plays a role in collecting and gathering the soil after screening. Through the above structure, the cooperation of the limiting block 21 and the limiting frame 22 realizes the function of limiting the movement of the screening plate 2, so that the screening plate 2 maintains a fixed movement path when moving, which improves the stability of the screening plate 2 when screening soil, improves the screening efficiency, and improves the stability of the device.

[0028] like Figure 1 , Figure 4 and Figure 5As shown, a conveyor belt 3 is fixed to the inner wall of the main housing 1, and a positioning block 31 is fixed to the surface of the conveyor belt 3. A collection box 32 is set inside the positioning block 31. During operation, before collecting soil, the operator can place the collection box 32 above the conveyor belt 3 and use the positioning block 31 to limit its movement. At this time, the conveyor belt 3 can be started to transport the collection box 32 to the collection position. When the soil falls to the bottom of the main housing 1, it will fall into the collection box 32. After the collection box 32 has finished collecting, the conveyor belt 3 can be started again to transport the collection box 32 back to the initial position and remove it. Through the above structure, the conveyor belt 3 realizes the function of quickly transporting soil samples, so that the soil remains stable during the movement process, reducing the pollution and impact on the soil during manual transfer, and improving the stability and practicality of the device.

[0029] like Figure 1 As shown, an observation slot 401 is provided inside the main housing 1. During operation, a glass plate is installed on the inner wall of the observation slot 401, allowing the soil to be observed in real time during sieving, thereby controlling the amount of soil added. The main housing 1 serves as the overall support and fixation. Through the above structure, the observation slot 401 enables the function of quickly observing the inside of the main housing 1, allowing the soil sieving operation to be observed in real time, providing convenience for the timing of soil addition and removal, and improving the intuitiveness and convenience of the device.

[0030] like Figure 3 As shown, the outer wall of the limiting block 21 and the inner wall of the limiting frame 22 are both coated with a friction-reducing coating. During operation, the friction-reducing coating reduces the friction between the limiting block 21 and the limiting frame 22, thus reducing long-term wear and tear and improving service life. Through this structure, the friction-reducing coating prevents the limiting block 21 and the limiting frame 22 from being worn down by friction after prolonged use, reducing maintenance costs and improving the durability of the device.

[0031] like Figure 3 As shown, the screening plate 2 is made of lightweight stainless steel. During operation, the use of lightweight stainless steel in the screening plate 2 makes it more adaptable to different soil conditions and improves its corrosion resistance. Through the above structure, the use of lightweight stainless steel in the screening plate 2 ensures that it will not be corroded or worn after long-term soil screening, thus extending its service life, reducing maintenance costs, and improving the corrosion resistance and adaptability of the device.

[0032] During operation, after soil is added into the main housing 1 from the feed hopper 101, the operator can start the motor 12. The motor 12 drives the polarization shaft 13 to rotate, which in turn pushes the vibrating block 15 to reciprocate. The movement of the vibrating block 15 then drives the connecting shaft 16 to move, resulting in rapid reciprocating motion of the connecting shaft 16. The main housing 1, the first fixing block 11, and the second fixing block 14 provide overall support and fixation. During operation, when the connecting shaft 16 moves, it drives the connecting block 161 to move. When the 61 unit moves, it drives the screening plate 2 to move, causing the screening plate 2 to move rapidly back and forth, thereby screening the soil through the screening trough 201 and improving the uniformity of soil particles. The main housing 1 plays a role in overall support and fixation. During operation, when the screening plate 2 moves, it drives the limiting block 21 to move. When the limiting block 21 moves, its outer wall slides against the inner wall of the limiting frame 22, so that the screening plate 2 remains stable during movement. The screening plate 2 and the main housing 1 play a role in overall support and fixation. The hopper 102 plays a role in collecting... The function of collecting and screening soil: During operation, before collecting the soil, the operator can place the collection box 32 above the conveyor belt 3 and use the positioning block 31 to limit it. At this time, the conveyor belt 3 can be started to transport the collection box 32 to the collection position. When the soil falls to the bottom of the main housing 1, it will fall into the collection box 32. After the collection box 32 has finished collecting, the conveyor belt 3 can be started again to transport the collection box 32 back to the initial position and take it out. During operation, the inner wall of the observation slot 401 is equipped with a glass plate so that the soil can be screened. The soil input can be monitored in real time, thereby controlling the amount of soil added. The main housing 1 plays a role in overall support and fixation. During operation, the outer wall of the limiting block 21 and the inner wall of the limiting frame 22 are sprayed with a friction-reducing coating to reduce the friction between the limiting block 21 and the limiting frame 22, thereby reducing the wear of the limiting block 21 and the limiting frame 22 due to long-term friction and improving their service life. During operation, the screening plate 2 is made of lightweight stainless steel, which makes the screening plate 2 more adaptable to different soil conditions and improves its corrosion resistance.
