Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, and more specifically to a soil drying and screening device for soil detection. Background Art

[0002] Soil testing refers to the use of appropriate analytical methods to determine the soil's physical and chemical indicators, heavy metals, inorganic substances, organic matter, dioxins and other material components that have an important impact on human health and maintaining ecological balance, thereby monitoring and predicting soil environmental quality.

[0003] Fresh soil samples contain more water, which will affect the concentration and distribution of various substances in the soil samples, resulting in the accuracy of the test results being affected. Drying can remove excess water in the soil, so that the moisture content of the soil samples reaches a stable state, thereby ensuring the accuracy and reliability of the test results. Soil samples are mixed with non-soil materials such as plant residues, stones, tiles, etc. These impurities will interfere with the process and results of soil testing. Through the screening device, these impurities can be effectively removed to improve the accuracy and precision of the test.

[0004] After searching, it was found that a soil drying and screening device for soil detection was disclosed in the document with publication number CN219943532U. The document has the function of drying the soil, but when processing sticky soil, due to the sticky effect between soil particles, they are easy to pile up tightly to form relatively static clumps. This stacking state not only leads to insufficient contact between the soil and the heat source, thereby reducing the heat transfer efficiency, but also makes it difficult for the moisture inside the soil to be effectively evaporated, resulting in unsatisfactory drying efficiency. For this reason, we propose a soil drying and screening device for soil detection. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model proposes a soil drying and screening device for soil testing, which can effectively stir the soil and ensure that the soil is in full contact with the heat source, thereby greatly improving the heat transfer efficiency and further significantly improving the drying efficiency, which is facilitating subsequent soil testing.

[0006] In order to solve the above technical problems, the utility model proposes a soil drying and screening device for soil detection, comprising a material storage barrel and a pressure plate, wherein the pressure plate is located in the material storage barrel, a groove is provided at the bottom of the pressure plate, a plurality of sliding sleeves are fixedly connected to the inner wall of the pressure plate, a plurality of inner walls of the sliding sleeves are slidably connected to stirring rods, and a plurality of bottoms of the stirring rods are embedded with rotatable balls;

[0007] The tops of the multiple stirring rods are fixedly connected with connecting rods, the tops of the multiple connecting rods pass through the sliding sleeve and are slidably connected with it, the circumferential outer walls of the multiple connecting rods are sleeved with first springs, and the circumferential outer walls of the multiple connecting rods are fixedly connected with limiting sleeves.

[0008] Furthermore, one end of the first spring is fixedly connected to the inner wall of the sliding sleeve, and the other end of the first spring is fixedly connected to the stirring rod.

[0009] Furthermore, a plurality of heating tubes are fixedly connected to the inner wall of the storage barrel.

[0010] Furthermore, a motor is fixedly connected to the inner wall of the storage barrel, a fixed shaft is fixedly connected to the output end of the motor, and the top of the fixed shaft passes through the storage barrel and is rotatably connected thereto;

[0011] The top of the fixed shaft is fixedly connected with a fixed platform, and the top of the fixed platform is fixedly connected with a vibrator.

[0012] Furthermore, a convex plate is installed at the movable end of the vibrator, and a screen is fixedly connected to the circumferential outer wall of the convex plate.

[0013] Furthermore, a mounting bracket is fixedly connected to the circumferential outer wall of the storage barrel, a cylinder is fixedly connected to the top of the mounting bracket, an output end of the cylinder passes through the mounting bracket and extends to below it, a connecting shaft is fixedly connected to the output end of the cylinder, and the bottom of the connecting shaft is fixedly connected to the top of the pressure plate.

[0014] Furthermore, a fixing sleeve is fixedly connected to the circumferential outer wall of the connecting shaft, a second spring is sleeved on the circumferential outer wall of the connecting shaft, and a sealing cover is slidably connected to the circumferential outer wall of the connecting shaft.

[0015] Furthermore, the top of the second spring is fixedly connected to the fixing sleeve, and the bottom of the second spring is fixedly connected to the sealing cover.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the utility model, when the pressure plate moves downward, the pressure plate drives multiple stirring rods to penetrate into the screen. At this time, the ball at the bottom of the stirring rod is in close contact with the top of the convex plate. The design of the ball reduces the friction between the stirring rod and the convex plate, making the stirring process smoother. When the convex plate rotates, the stirring rod can effectively stir the soil to ensure that the soil is in full contact with the heat source, thereby greatly improving the heat transfer efficiency. At the same time, this stirring action also helps the moisture inside the soil to evaporate quickly and effectively, thereby significantly improving the drying efficiency, which is beneficial to subsequent soil testing.

[0018] 2. In the utility model, the soil is evenly spread on the top of the convex plate, and then the soil is efficiently heated by the heating tube. At the same time, the motor drives the fixed shaft to rotate, thereby driving the vibrator to start working, and the convex plate and the screen rotate accordingly. The vibrator effectively disperses the soil on the top of the convex plate through the centrifugal force generated. In addition, the vibration generated by the vibrator further refines the soil and disperses it into small pieces or powder. After being screened by the screen, the refined soil rolls out of the mesh, realizing a convenient feeding process. This process not only improves the efficiency of soil treatment, but also helps to ensure sufficient contact between the soil and the heat source, thereby optimizing the drying effect.

[0019] 3. In the utility model, the design of the convex plate cleverly promotes the rolling of the soil and effectively prevents the accumulation of soil during the heating process. At the same time, the grooves arranged at the bottom of the pressure plate ensure sufficient contact between the pressure plate and the top of the convex plate, so that the soil can be processed more delicately during the rolling process, which not only improves the soil processing efficiency, but also ensures the uniformity and fineness of the soil quality.

[0020] 4. In the utility model, when the soil clumps after drying, the cylinder pushes the pressure plate downward, and the pressure plate applies a moderate squeezing force to the agglomerated soil, effectively crushing the agglomerates, thereby making the soil finer. This process not only improves the effect of soil treatment, but also ensures the accuracy of subsequent soil testing.

[0021] 5. In the utility model, when the connecting shaft moves downward, the sealing cover is tightly buckled on the top of the storage barrel by the elastic force of the second spring. This design cleverly reduces the heat loss inside the storage barrel and ensures the efficient drying process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 3 and Figure 4 As shown, a soil drying and screening device for soil detection includes a pressing plate 5 and a storage barrel 1. The pressing plate 5 is located in the storage barrel 1. A groove 20 is provided at the bottom of the pressing plate 5. A plurality of sliding sleeves 6 are fixedly connected to the inner wall of the pressing plate 5. A stirring rod 7 is slidably connected to the inner wall of the plurality of sliding sleeves 6. A rotatable ball 8 is embedded at the bottom of the plurality of stirring rods 7. A connecting rod 9 is fixedly connected to the top of the plurality of stirring rods 7. The top of the plurality of connecting rods 9 passes through the sliding sleeve 6 and is slidably connected thereto. A first spring 10 is sleeved on the outer circumference wall of the plurality of connecting rods 9. One end of the first spring 10 is fixedly connected to the inner wall of the sliding sleeve 6. The other end of the first spring 10 is fixedly connected to the stirring rod 7. A limiting sleeve 11 is fixedly connected to the outer circumference wall of the plurality of connecting rods 9. When the pressing plate 5 moves downward, the pressing plate 5 drives the plurality of stirring rods 7 to penetrate into the interior of the screen 21. At this time, the ball 8 at the bottom of the stirring rod 7 is in close contact with the top of the convex plate 19. The design of the ball 8 reduces the friction between the stirring rod 7 and the convex plate 19, making the stirring process smoother. When the convex plate 19 rotates, the stirring rod 7 can effectively stir the soil to ensure that the soil is in full contact with the heat source, thereby greatly improving the heat transfer efficiency. At the same time, this stirring action also helps the moisture inside the soil to evaporate quickly and effectively, thereby significantly improving the drying efficiency, which is beneficial to subsequent soil testing.

[0031] A discharge window (not shown) is provided on the storage barrel 1. The setting of the discharge window allows the dried and screened soil to be easily discharged from the discharge window. By opening the discharge window, the processed soil can be easily exported for subsequent soil testing.

[0032] like Figure 2As shown, a plurality of heating tubes 22 are fixedly connected to the inner wall of the storage barrel 1. Through the operation of the heating tubes 22, the temperature inside the storage barrel 1 can be quickly increased, so that the moisture in the soil can be effectively evaporated, thereby achieving the purpose of drying. In addition, the heating tubes 22 can also cooperate with the stirring rod 7 and the convex plate 19 to ensure that the soil is evenly heated during the drying process, avoiding local overheating or uneven drying. This uniform heating method not only improves the drying efficiency, but also ensures the quality of the dried soil, which is conducive to subsequent soil testing.

[0033] like Figure 2 As shown, the inner wall of the storage barrel 1 is fixedly connected to a motor 15, and the output end of the motor 15 is fixedly connected to a fixed shaft 16. The top of the fixed shaft 16 passes through the storage barrel 1 and is rotatably connected thereto; the top of the fixed shaft 16 is fixedly connected to a fixed platform 17, and the top of the fixed platform 17 is fixedly connected to a vibrator 18, and a protective cover is provided on the outside of the vibrator 18. The motor 15 drives the fixed shaft 16 to rotate, thereby driving the vibrator 18 to start working, and causing the convex plate 19 and the screen 21 to rotate accordingly. The vibrator 18 effectively disperses the soil on the top of the convex plate 19 through the centrifugal force generated. In addition, the vibration generated by the vibrator 18 further refines the soil and disperses it into small pieces or powder.

[0034] like Figure 2 , Figure 5 and Figure 6 As shown, a convex plate 19 is installed at the movable end of the vibrator 18. The design of the convex plate cleverly promotes the rolling of the soil and effectively prevents the accumulation of the soil during the heating process. At the same time, the grooves set at the bottom of the pressure plate ensure the full contact between the pressure plate and the top of the convex plate, so that the soil can be processed more delicately during the rolling process, which not only improves the soil processing efficiency, but also ensures the uniformity and fineness of the soil quality. The outer wall of the circumference of the convex plate 19 is fixedly connected with a screen 21. The soil is screened by the screen 21, and the refined soil rolls out of the mesh, realizing a convenient material discharge process.

[0035] like Figure 1 and Figure 3 As shown, the outer circumferential wall of the storage barrel 1 is fixedly connected to the mounting frame 2, the top of the mounting frame 2 is fixedly connected to the cylinder 3, the output end of the cylinder 3 passes through the mounting frame 2 and extends to the bottom thereof, the output end of the cylinder 3 is fixedly connected to the connecting shaft 4, and the bottom of the connecting shaft 4 is fixedly connected to the top of the pressure plate 5. The outer circumferential wall of the connecting shaft 4 is fixedly connected to a fixing sleeve 13, the outer circumferential wall of the connecting shaft 4 is sleeved with a second spring 14, the outer circumferential wall of the connecting shaft 4 is slidably connected to a sealing cover 12, the top of the second spring 14 is fixedly connected to the fixing sleeve 13, and the bottom of the second spring 14 is fixedly connected to the sealing cover 12.

[0036] Working principle: the soil is evenly spread on the top of the convex plate 19, and then the soil is efficiently heated by the heating tube 22. At the same time, the motor 15 drives the fixed shaft 16 to rotate, thereby driving the vibrator 18 to start working, and the convex plate 19 and the screen 21 rotate accordingly. The centrifugal force generated by the vibrator 18 effectively disperses the soil on the top of the convex plate 19. In addition, the vibration generated by the vibrator 18 further refines the soil and disperses it into small pieces or powder. After being screened by the screen 21, the refined soil rolls out from the mesh.

[0037] The cylinder 3 drives the sealing cover 12 and the pressure plate 5 to move downward through the connecting shaft 4. When the connecting shaft 4 moves downward, the sealing cover 12 is tightly buckled on the top of the storage barrel 1 by the elastic force of the second spring 14;

[0038] The pressure plate 5 drives the multiple stirring rods 7 to penetrate into the screen 21. At this time, the ball 8 at the bottom of the stirring rod 7 is in close contact with the top of the convex plate 19. The design of the ball 8 reduces the friction between the stirring rod 7 and the convex plate 19, making the stirring process smoother. When the convex plate 19 rotates, the stirring rod 7 can effectively stir the soil to ensure that the soil is in full contact with the heat source, thereby greatly improving the heat transfer efficiency. At the same time, this stirring action also helps the moisture inside the soil to evaporate quickly and effectively, thereby significantly improving the drying efficiency.

[0039] When the soil lumps up after drying, the cylinder 3 pushes the pressing plate 5 to move downward, and the pressing plate 5 applies a moderate squeezing force to the agglomerated soil, effectively crushing the agglomerates, thereby making the soil finer.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
