[0033] The anti-blocking structure includes two front-to-back symmetrical wave plates 212 arranged below the cleaning plate 210. The wave plates 212 are fixed to the inner wall of the box body 100. A plurality of telescopic springs are connected between the cleaning plate 210 and the sliding plate 208. A protrusion 211 is fixed at the front and rear ends of the cleaning plate 210. The lower end of the protrusion 211 is arc-shaped and slides with the wave plate 212.

[0034] The material control component includes two symmetrical unloading platforms 206 arranged above the lead screw 207. The two unloading platforms 206 are arranged to be inclined downward at one end close to each other. A slide groove is opened at the lower end of the unloading platform 206. A baffle 205 is slidably installed inside the slide groove. The two baffles 205 are arc-shaped at one end close to each other. A return spring is connected between the baffle 205 and the slide groove. Two symmetrical upper wedge blocks 202 are arranged on the front and rear sides of the filter plate 201. The upper wedge blocks 202 are fixed to the filter plate 201 through a connecting plate. A lower wedge block 203 is arranged below the upper wedge block 202. The lower wedge block 203 and the upper wedge block 202 are inclined at one end close to each other, and slide in cooperation. The lower wedge block 203 is fixed to the baffle 205. A connecting rod 204 is connected, and the connecting rod 204 is slidably connected to the inner wall of the slide groove. The impurities in the soil are screened and filtered through the screening component. During the screening process, the soil on the filter plate 201 is moved back and forth to both sides by the cleaning component, so that the soil is spread to both sides, increasing the filtering area, and the soil adhering to the surface of the filter plate 201 is scraped off, thereby improving the utilization rate of the filter plate 201. When the soil is moved, the anti-blocking structure is used to apply a certain vibration to the filter plate 201, so that the soil on the filter plate 201 is turned over, and the impurities inside follow the turning over, thereby reducing the impurities clogging in the filter holes, and the vibration is more conducive to the discharge of the soil, which speeds up the filtration speed and improves the filtration efficiency.

[0035] Working principle: first, pour the soil to be tested into the upper side of the box body 100 through the feed port at the upper end of the box body 100, and fall into the bottom of the lower bin 309, drive the rotating motor 301 to drive the rotating shaft 302 to rotate, drive the stirring plate 303 at the lower side to rotate, and at the same time drive the multiple stirring blades 305 on the upper fixed shaft sleeve 304 to rotate, so as to stir and flip the internal soil in all directions. While stirring, the heating tube 306 in the heating box 308 at the rear end of the box body 100 works to heat the internal air, and then use multiple blowing fans 307 to blow the hot air into the box body 100 to dry the stirred soil, reduce the later relatively moist soil from adhering to the filter plate 201, and when the rotating shaft 302 rotates, the rotating plate 310 at the lower end is driven to rotate, and then when the lower feeding port on the rotating plate 310 is connected with the discharge port at the bottom of the lower bin 309, the soil flows out indirectly from between the lower feeding port and the discharge port to discharge the soil inside the lower bin 309.

[0036] The dried soil falls onto the filter plate 201 below, driving the moving motor 209 to rotate the lead screw 207, driving the sliding plate 208 to slide back and forth, and driving the cleaning plate 210 below to slide back and forth, spreading the soil on the filter plate 201 to both sides, increasing the contact area between the soil and the filter plate 201, improving the utilization rate of the filter plate 201, and scraping off the soil adhering to the surface of the filter plate 201. The provided shield 216 blocks the fallen soil to prevent the soil from falling onto the lead screw 207 and adhering to the lead screw 207 to affect the movement of the sliding plate 208. When the cleaning plate 210 moves back and forth, the protrusions 211 at the front and rear ends contact the front and rear ends. The wave plates 212 at both ends slide together, thereby driving the cleaning plate 210 to vibrate up and down when moving back and forth, thereby driving the filter plate 201 to vibrate up and down, and then flipping the soil on the surface and the impurities inside, thereby reducing the clogging of impurities in the filter holes, and the vibration is more conducive to the discharge of soil, which speeds up the filtration speed and improves the filtration efficiency. The impurities after filtration remain above the filter plate 201, and the cleaning plate 210 pushes the filtered impurities to both sides, and pushes the impurities to the material holding frame 214 in the waste bin 215 on both sides for collection. The filtered soil falls into the material holding frame 214 below the filter plate 201 for collection.

[0037] When the amount of soil discharged is large, the filter plate 201 cannot filter a large amount of soil quickly. Therefore, due to the heavy amount of soil, the filter plate 201 will be pressed downward, causing the filter plate 201 to move downward, thereby driving the upper wedge blocks 202 on the upper ends of the connecting plates on both sides to move downward, squeezing the lower wedge blocks 203 below, driving the lower wedge blocks 203 on both sides to move toward each other, and driving the baffles 205 on both sides to move toward each other, thereby closing the gap between the discharge platforms 206 on both sides, and using the baffles 205 on both sides to block the falling soil, thereby reducing the amount of soil falling on the filter plate 201 and alleviating the filtration pressure of the filter plate 201, so that when the weight of the soil on the filter plate 201 increases, the filtration pressure increases, and thus the amount of soil discharged is adaptively reduced, realizing the role of soil adaptive discharge, which can effectively alleviate the filtration pressure of the filter plate 201 and improve the filtration efficiency.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
