[0031] 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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a soil sample drying device, including a heating chamber 1, a switch door 11 on the side wall of the heating chamber 1, multiple arrays of heating boxes 12 fixedly connected to the inner wall of the heating chamber 1, a rotating support assembly 2 inside the heating chamber 1, the rotating support assembly 2 including a support column 21, a ring 22 fixedly connected to the end of the support column 21, a support plate 23 rotatably connected to the surface of the ring 22, a storage box 29 placed on the surface of the support plate 23, multiple arrays of support columns 21 provide stable support for the ring 22 and allow the support plate 23 to rotate along the surface of the ring 22, the support plate 23 provides a placement platform for placing the storage box 29, the storage box 29 contains soil samples to be dried.

[0033] Reference Figure 2 - Figure 3The support plate 23 has a groove 24 on its surface. Two symmetrically arranged sliding plates 25 are slidably connected inside the groove 24. Clamping plates 26 are fixedly connected to the surface of each sliding plate 25. The two sets of sliding plates 25 are threaded together by a bidirectional threaded rod 27, which passes through and is rotatably connected to the side wall of the support plate 23. A rotating wheel 28 is fixedly connected to the end of the bidirectional threaded rod 27. The groove 24 provides a track for the two sets of sliding plates 25 to slide along. The rotating wheel 28 facilitates the rotation of the bidirectional threaded rod 27, thereby causing the two sets of sliding plates 25 and the clamping plate 26 to move towards each other, thus clamping and fixing the storage box 29 placed on the surface of the support plate 23, ensuring the stability of the storage box 29. A motor 210 is fixedly connected to the inner wall of the heating chamber 1. The output shaft of the motor 210 is fixedly connected to the bottom surface of the support plate 23. The motor 210 drives the support plate 23 to rotate along the surface of the ring 22 through its output shaft, thereby causing the storage box 29 to rotate synchronously, improving the uniformity of heating of the soil sample.

[0034] Reference Figure 2 , Figure 4 The heating chamber 1 is equipped with a cutting assembly 3, which is used to cut the soil sample contained in the storage box 29, increasing the surface area of ​​the soil sample and thus improving drying efficiency. The cutting assembly 3 includes a fixed shaft 31, which is fixedly connected to the inner wall of the heating chamber 1. A sleeve 32 is fitted onto the outer surface of the fixed shaft 31. Multiple arrays of cutting blades 33 are fixedly connected to the side wall of the sleeve 32. A limiting groove 34 is formed on the outer wall of the sleeve 32. A limiting block 35 is fixedly connected to the side wall of the fixed shaft 31. The limiting block 35 is slidably connected inside the limiting groove 34. Through the cooperation of the limiting block 35 and the limiting groove 34, the fixed shaft 31 and the sleeve 32 are kept in a stable position and do not rotate relative to each other. Under the action of gravity, the sleeve 32 and the cutting blades 33 slide downward and extend into the storage box 29. By rotating the storage box 29, the cutting blades 33 remain in a fixed position, thus achieving the cutting of the soil sample. A lifting plate 36 is fixedly connected to the top of the sleeve 32. The lifting plate 36 facilitates the upward movement of the sleeve 32, allowing the cutting blade 33 to be moved outside the storage box 29, thus making it easier to retrieve the storage box 29.

[0035] Working principle: When in use, the soil sample to be dried is placed on the surface of the support plate 23. The rotating wheel 28 rotates the bidirectional threaded rod 27, which drives the two sets of sliding plates 25 and clamping plates 26 to move towards each other, clamping and fixing the storage box 29 placed on the surface of the support plate 23 to ensure the stability of the storage box 29. The motor 210 drives the support plate 23 to rotate along the surface of the ring 22 through its output shaft, so that the storage box 29 rotates synchronously, improving the uniformity of heating of the soil sample.

[0036] During the rotation of the storage box 29, the fixed shaft 31 and the sleeve 32 are kept in a stable position by the cooperation of the limiting block 35 and the limiting groove 34, and no relative rotation occurs. Under the action of gravity, the sleeve 32 and the cutting blade 33 slide downward and extend into the storage box 29. By rotating the storage box 29 and fixing the position of the cutting blade 33, the soil sample is cut, increasing the surface area of ​​the soil sample and thus improving the drying efficiency.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
