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.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] A soil sample pretreatment structure for soil testing includes a base 1 and a drying fan 2. The bottom of the drying fan 2 is provided with a holding and turning component 3, and the interior of the holding and turning component 3 is provided with a reverse turning component 4.
[0029] The container tilting assembly 3 includes a first upright plate 301 and a second upright plate 302. The first upright plate 301 and the second upright plate 302 are respectively fixedly connected to the two sides of the top of the base 1. A ventilation mesh tube 303 is provided between the first upright plate 301 and the second upright plate 302. A first support tube 304 is fixedly connected to the left side of the ventilation mesh tube 303, and a second support tube 305 is fixedly connected to the right side of the ventilation mesh tube 303. The opposite sides of the first support tube 304 and the second support tube 305 pass through the first upright plate 301 and the second upright plate 302 respectively. The surfaces of the first support tube 304 and the second support tube 305 are rotatably connected to the inner walls of the first upright plate 301 and the second upright plate 302 respectively through bearings. A first drive motor 306 is provided on the left side of the first upright plate 301. The output shaft of the first drive motor 306 is fixedly connected to the left side of the first support tube 304.
[0030] In this embodiment: by setting up a base 1, a drying fan 2, a holding and turning component 3, and a reverse turning component 4, the base 1 provides a supporting foundation for the entire device during use. The drying fan 2 improves the drying efficiency of soil samples through airflow. The holding and turning component 3 holds the soil samples to be dried and continuously turns the soil, thereby improving the efficiency and uniformity of the soil sample drying process. The reverse turning component 4 continuously turns the soil samples in the opposite direction to the holding and turning component 3, further improving the efficiency and uniformity of the soil sample drying process. Furthermore, the turning and reverse turning continuously disperse and mix the soil samples, making the internal components of the soil samples uniform and ensuring the accuracy and representativeness of subsequent test results.
[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the reverse toggle assembly 4 includes a second drive motor 401, which is located on the right side of the second upright plate 302. The output shaft of the second drive motor 401 is fixedly connected to a rotating rod 402. The left side of the rotating rod 402 passes through the second support tube 305 and the ventilation mesh tube 303 in sequence and extends into the inner cavity of the first support tube 304. The side of the rotating rod 402 near the inner wall of the ventilation mesh tube 303 is rotatably connected to the inner wall of the ventilation mesh tube 303 through a bearing.
[0032] Specifically, such as Figure 2 , Figure 4 As shown, a toggle plate 403 is fixedly connected to the surface of the rotating rod 402. There are several toggle plates 403, which are distributed alternately on the surface of the rotating rod 402.
[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a second fixed bracket 404 is fixedly connected to the bottom of the second drive motor 401, and the side of the second fixed bracket 404 near the second upright plate 302 is fixedly connected to the second upright plate 302.
[0034] In this embodiment: by setting up a second drive motor 401, a rotating rod 402, a toggle plate 403, and a second fixed bracket 404, in use, the output shaft of the second drive motor 401 is started, causing the rotating rod 402 to rotate in the opposite direction to the ventilation net cylinder 303. The reverse rotation of the rotating rod 402 will drive multiple toggle plates 403 to toggle the soil sample in the ventilation net cylinder 303 in the opposite direction, thereby further improving the efficiency and uniformity of the soil sample drying process. Furthermore, by flipping and toggle in the opposite direction, the soil sample can be continuously broken up and mixed, making the internal composition of the soil sample uniform, which can ensure the accuracy and representativeness of subsequent test results. The second fixed bracket 404 can support and fix the second drive motor 401.
[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the top of the ventilation screen cylinder 303 is provided with an inlet / outlet 5, and the top of the inlet / outlet 5 is provided with a screen cover 6. The two sides of the front side of the screen cover 6 are rotatably connected to the two sides of the front side of the top of the ventilation screen cylinder 303 through a steering shaft, and the rear sides of the two sides of the screen cover 6 are connected to the rear sides of the top of the two sides of the ventilation screen cylinder 303 through a locking buckle.
[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a first fixed bracket 7 is fixedly connected to the bottom of the first drive motor 306, and the side of the first fixed bracket 7 near the first upright plate 301 is fixedly connected to the first upright plate 301.
[0037] In this embodiment: by setting the inlet and outlet 5, the soil sample that needs to be air-dried can be conveniently added into the ventilation net cylinder 303. After air-drying, the ventilation net cylinder 303 can be flipped so that the inlet and outlet 5 faces downward, and the air-dried soil sample can be unloaded. By setting the net cover 6, the inlet and outlet 5 of the ventilation net cylinder 303 can be closed during the air-drying process. By setting the first fixed bracket 7, the first drive motor 306 can be supported and fixed.
[0038] Specifically, such as Figure 1 As shown, support frames 8 are fixedly connected to both sides of the air drying fan 2, and the two support frames 8 are fixedly connected to the top of the first vertical plate 301 and the second vertical plate 302 respectively.
[0039] Specifically, such as Figure 1 , Figure 2 As shown, a guide plate 9 is provided at the bottom of the ventilation screen 303, and a support plate 10 is fixedly connected to both sides of the bottom of the guide plate 9. The bottom of the support plate 10 is fixedly connected to the top of the base 1.
[0040] In this embodiment: by setting the support frame 8, the air drying fan 2 can be supported and fixed; by setting the guide plate 9, the air-dried soil sample can be guided when it is fed; and by setting the support plate 10, the guide plate 9 can be supported and fixed.
[0041] Working Principle: In use, the soil sample to be air-dried is first placed into the ventilation mesh cylinder 303 through the inlet / outlet 5. Then, the mesh cover 6 is closed. The ventilation mesh cylinder 303 holds the soil sample to be air-dried. The air-drying fan 2 is then started, using airflow to assist in the air-drying of the soil sample in the ventilation mesh cylinder 303. Simultaneously, the first drive motor 306 is started, causing its output shaft to drive the first support pipe 304 to rotate within the first vertical plate 301 via bearings. The first support pipe 304 drives the ventilation mesh cylinder 303 to rotate. At the same time, the second support pipe 305 also rotates within the second vertical plate 302 via bearings. This rotation of the ventilation mesh cylinder 303 continuously rotates the soil sample inside, thereby improving the air-drying efficiency of the soil sample. The drying process improves efficiency and uniformity. Simultaneously, the second drive motor 401 is activated, causing its output shaft to drive the rotating rod 402 to rotate in the opposite direction to the ventilation screen 303. This reverse rotation of the rotating rod 402 drives multiple actuating plates 403 to actuate the soil sample within the ventilation screen 303, further enhancing the efficiency and uniformity of the drying process. Furthermore, the flipping and actuation continuously disperse and mix the soil sample, ensuring uniform composition and guaranteeing the accuracy and representativeness of subsequent test results. After drying, the first drive motor 306 flips the ventilation screen 303 so that the inlet / outlet 5 faces downwards, and then the screen cover 6 is opened to discharge the dried soil sample. The discharge soil sample is then guided by the guide plate 9.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
