Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil testing technology, and in particular to a soil quick-drying device for soil testing. Background Technology
[0002] The main purpose of rapidly drying soil in soil testing is to eliminate the interference of moisture on experimental results. In experiments that test whether soil contains organic matter, using dry soil can avoid the interference of moisture on experimental phenomena and ensure the accuracy of the experiment. If fresh soil is used, the moisture in the soil will evaporate, which will interfere with the experiment and may lead to the measurement result being too low.
[0003] Traditional soil drying methods commonly involve natural air drying, but this method still has the following drawbacks: natural air drying takes too long, especially during periods of continuous rain or high humidity, which greatly extends the drying time and affects the efficiency and progress of agricultural production. For larger soil tracts, the rate of moisture removal from their interior is significantly slower, resulting in the exterior being completely dry while the interior remains damp, which may ultimately lead to poor drying results and affect the later use of the soil. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new compositional structure that differs from existing technologies. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil quick-drying device for soil testing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A soil quick-drying device for soil testing includes a housing. A fixed shell is fixedly connected to the inner top wall of the housing.

[0023] Reference Figures 1-3A soil quick-drying device for soil testing includes a housing 4. A fixed shell 7 is bolted to the top inner wall of the housing 4. A crushing component is installed inside the fixed shell 7. The crushing component includes multiple connecting shafts 16, which are rotatably connected to the bottom inner wall of the fixed shell 7. The top ends of the multiple connecting shafts 16 pass through the housing 4 and are keyed to a first bevel gear 6. Multiple cutting blades 17 are bolted to the outside of the connecting shafts 16 and are located inside the fixed shell 7. Multiple drainage holes 18 are opened at the bottom of the fixed shell 7. The first bevel gear 6 drives the connecting shafts 16 to rotate, thereby causing the cutting blades 17 to further crush the soil inside the fixed shell 7. Soil particles smaller than the diameter of the drainage holes 18 fall into the guide shell 8 through the drainage holes 18. A feed inlet is opened at the top of the housing 4, and a feed pipe 5 is fixedly connected to the feed inlet. The top of the fixed shell 7 is an open design, and the bottom of the feed pipe 5 is open. The end is located at the opening of the fixed shell 7. The soil that needs to be dried outside enters the fixed shell 7 inside the shell 4 through the feed pipe 5. The top of the shell 4 is rotatably connected to the rotating shaft 15. The top outer wall of the shell 4 is provided with a power component that drives the rotating shaft 15 and the crushing component to rotate. The power component includes a second bevel gear 14, which is keyed to the top of the rotating shaft 15. The first bevel gear 6 meshes with the second bevel gear 14. The rotation of the motor 1 causes the rotating shaft 15 to drive the second bevel gear 14 to rotate, thereby causing the first bevel gear 6 to drive the connecting shaft 16 to rotate. The top outer wall of the shell 4 is fixed with a dustproof shell 2 by bolts. The top outer wall of the dustproof shell 2 is fixed with a motor 1 by bolts. The top of the rotating shaft 15 passes through the shell 4 and is fixed to one end of the output shaft of the motor 1. The first bevel gear 6 and the second bevel gear 14 are located inside the dustproof shell 2. The dustproof shell 2 can protect the first bevel gear 6 and the second bevel gear 14.
[0024] In this invention, it should be noted that a guide shell 8 is bolted to the inner wall of the housing 4. The guide shell 8 is conical, and multiple heating wires 9 are fixed to the outer side of the guide shell 8. The heating wires 9 heat and dry the soil inside the guide shell 8. Multiple arc-shaped plates 20 and scrapers 19 are bolted to the bottom end of the rotating shaft 15. The rotation of the arc-shaped plates 20 can change the movement path of the soil, allowing the soil to contact the guide shell 8 more fully and increasing the soil's residence time for further heating. The scrapers 19 are in close contact with the inner wall of the guide shell 8. The rotation of the rotating shaft 15 causes the arc-shaped plates 20 and scrapers 19 to move together. Rotation of plate 19 causes the arc plate 20 to assist in stirring and further disperse the soil entering the guide shell 8. At the same time, scraper 19 scrapes away the soil dispersed and falling onto the inner wall of the guide shell 8, causing the soil to move downwards along the slope of the guide shell 8. Two limiting plates 10 are fixed between the inner walls on both sides of the bottom of the shell 4 by bolts. A collection box 3 is slidably connected between the two limiting plates 10. The setting of the limiting plates 10 not only restricts the position of the collection box 3, but also makes it easy for workers to install and disassemble the collection box 3, and to take out the dried soil.
[0025] In particular, the top of the collection box 3 is provided with multiple air inlets 11, and a drying assembly is provided on one side of the housing 4. The drying assembly includes a support plate, which is fixed to the outer wall of one side of the housing 4 by bolts. A fan 13 is fixed to the upper surface of the support plate by bolts. One end of the air outlet of the fan 13 extends into the interior of the housing 4 and is connected to a tapered tube 12, which is located above the air inlets 11. A feed inlet is provided in the middle of the top of the collection box 3, and the bottom of the guide shell 8 corresponds vertically to the position of the feed inlet. The soil after initial drying enters the collection box 3 through the guide shell 8. The fan 13 is started, and the fan 13 blows air out through the tapered tube 12 and further dries the soil in the collection box 3 through the air inlets 11.
[0026] Working principle: When soil drying is required, external soil enters the fixed shell 7 inside the housing 4 through the feed pipe 5. The motor 1 is started, and the rotation of the motor 1 causes the rotating shaft 15 to drive the second bevel gear 14 to rotate, thereby causing the first bevel gear 6 to drive the connecting shaft 16 to rotate. This causes the cutting blade 17 to further crush the soil inside the fixed shell 7. The crushed soil falls into the guide shell 8 through the leakage hole 18. The heating wire 9 is started to heat and dry the soil inside the guide shell 8. At the same time, the rotation of the rotating shaft 15 causes the arc plate 20 and scraper 19 to rotate, thereby causing the arc plate 20 to assist in stirring and further disperse the soil entering the guide shell 8. At the same time, the scraper 19 scrapes away the soil dispersed and falling onto the inner wall of the guide shell 8, causing the soil to move down the slope of the guide shell 8 until the initially dried soil enters the collection box 3. At the same time, the blower 13 is started, and the blower 13 blows air out through the conical pipe 12 and further dries the soil in the collection box 3 through the air inlet 11.
