[0002] Soil pretreatment is a prerequisite for accurate analysis of soil nutrients, heavy metals, and other indicators. Shaking is a core action in several key stages (such as sample sieving, reagent mixing and extraction, and digestion assistance) – shaking ensures homogenization of soil particles and sufficient contact between reagents and samples, guaranteeing the representativeness and accuracy of subsequent test results. In traditional pretreatment processes, the shaking stage is mostly manual: during sieving, operators need to repeatedly shake the sieve by hand, which is not only labor-intensive but also difficult to control stably in terms of shaking frequency and amplitude, leading to uneven sieving of soil particles and affecting the representativeness of subsequent sample weighing.

The upper end of the operating platform 103 is equipped with a flipping vibration mechanism for flipping the inner cylinder 105. This flipping vibration mechanism allows the inner cylinder 105 to be inverted for material removal. The inner cylinder 105 is equipped with a pulverizing mechanism for crushing soil samples. The pulverizing mechanism can crush the soil for subsequent testing. The inner cylinder 105 is equipped with a water replenishment mechanism for adding water into it. The upper end of the operating table 103 is equipped with a liquid collection mechanism for obtaining liquid. The upper end of the inner cylinder 105 is equipped with a filter cover assembly for water discharge. The filter cover assembly is used to filter the soil to prevent impurities from affecting subsequent testing. The bottom of the inner cylinder 105 is equipped with an ultrasonic generator for assisting in mixing. The ultrasonic generator vibration assists in soil dissolution and subsequent cleaning. The filter cover assembly includes a cover 108, which is threadedly connected to the upper port of the inner cylinder 105. The upper end of the cover 108 is provided with a water outlet pipe 107 for drainage, and a water outlet valve is provided at the position of the water outlet pipe 107. The center position of the cover 108 is provided with a handle 106, and the lower end of the cover 108 is provided with a filter plate 110 for filtering the test liquid. When the flipping and oscillating mechanism drives the outer box 100 to flip, the water outlet pipe 107 is set downward so that the port of the water outlet pipe 107 faces the liquid taking mechanism. Then the water outlet valve is opened, the target liquid is filtered through the filter plate 110, and then the liquid is discharged along the water outlet pipe 107 and collected by the taking cup 101. The liquid dispensing mechanism includes a dispensing positioning groove 102 set on the operating table 103. The inner end of the dispensing positioning groove 102 is provided with an arc-shaped end, and a dispensing cup 101 is provided at the position of the arc-shaped end. This makes it convenient to place the dispensing cup 101 at the end of the dispensing positioning groove 102 for dispensing. The water replenishment mechanism includes a heating ring pipe 304 sleeved on the outside of the inner cylinder 105. Multiple nozzles 305 are arrayed on the inner side of the heating ring pipe 304 to spray water into the outer box 100. The water inlet of the heating ring pipe 304 is connected to the upper end of the water supply pipe 302, and the lower end of the water supply pipe 302 is connected to the output end of the feed pump 301. The pumping end of the feed pump 301 extends into the water storage tank 300, which is located on the outside of the outer box 100. Water in the water storage tank 300 is fed into the heating ring pipe 304 by the feed pump 301, and then the water is sprayed into the outer box 100 along the nozzles 305 to replenish water in the soil. This water replenishment method also facilitates subsequent cleaning treatment. The bottom of the inner cylinder 105 is provided with a drain pipe 109 for drainage. Later, the solenoid valve on the drain pipe 109 is opened to drain the wastewater after cleaning. The crushing mechanism includes a stirring shaft 404 rotatably mounted at the bottom of the outer casing 100. Multiple stirring rods 403 are distributed on the surface of the stirring shaft 404 located inside the outer casing 100. Each stirring rod 403 is set at an acute angle to the horizontal plane, and multiple crushing discs 405 are distributed on its surface. The lower end of the stirring shaft 404 is connected to a second gear 402. One side of the second gear 402 meshes with a first gear 401. The first gear 401 is connected to the output end of a crushing motor 400. The crushing motor 400 is mounted at the bottom of the outer casing 100. Driven by the crushing motor 400, the first gear 401 and the second gear 402 engage, thereby driving the stirring shaft 404 to rotate. The stirring shaft 404 can drive the stirring rods 403 and the crushing discs 405 to rotate, thus thoroughly crushing the soil. The insulation structure includes an outer box 100 fitted outside the inner cylinder 105. The insulation chamber between the outer box 100 and the inner cylinder 105 is filled with liquid, which can be water or oil. The insulation chamber is equipped with a heating pipe 303 for heating the liquid. By energizing the heating pipe 303, the liquid is heated, thereby creating a heating environment outside the inner cylinder 105. Water bath heating ensures the uniformity of heating. Heat exchange fins are provided on the outer side of the inner cylinder 105 where the outer box 100 is located, which helps to improve heat exchange efficiency. The flipping and oscillating mechanism includes two symmetrically arranged support side plates 200. A rotating shaft 204 connected to the outer casing 100 is rotatably mounted on the support side plate 200. One of the rotating shafts 204 has a worm gear 203 at its end. A worm 201 is meshed on the lower side of the worm gear 203. The worm 201 is connected to a steering motor 202 for driving its rotation. Under the drive of the steering motor 202, the worm 201 and the worm gear 203 cooperate with each other, thereby driving the rotating shaft 204 to rotate.

[0021] Working principle: In actual use, soil is added to the outer casing 100. Driven by the crushing motor 400, the first gear 401 and the second gear 402 engage, thereby driving the stirring shaft 404 to rotate. The stirring shaft 404 can drive the stirring rod 403 and the crushing disc 405 to rotate, thus fully crushing the soil. After crushing, water from the water storage tank 300 is sent to the heating ring pipe 304 by the feed pump 301. Then, the water is sprayed into the outer casing 100 along the nozzle 305, completing the water replenishment of the soil. During the water replenishment process, the crushing mechanism can also assist in the removal of target elements from the soil. The liquid is dissolved by energizing the heating tube 303, thereby heating the liquid and creating a heating environment outside the inner cylinder 105. The water bath heating ensures the uniformity of heating, allowing the target liquid to reach the predetermined temperature. When the flipping and oscillating mechanism drives the outer box 100 to flip, the water outlet pipe 107 is set downward so that the port of the water outlet pipe 107 faces the liquid taking mechanism. Then the water outlet valve is opened, and the target liquid is filtered through the filter plate 110. The liquid is then discharged along the water outlet pipe 107 and collected by the material taking cup 101. Later, water is sprayed through the water replenishment mechanism, and then the wastewater is discharged through the drain pipe 109.
