Description

Technical Field

[0001] This utility model relates to the field of soil treatment technology, specifically to a soil crushing device capable of multi-stage filtration and screening. Background Technology

[0002] Soil treatment is an agricultural technique that uses pesticides applied to the soil or surface to achieve weed control through absorption by the roots or shoots of weeds. Its core methods include three stages: pre-sowing, pre-emergence, and post-emergence treatment. Application methods include spraying, mixing with soil, and broadcasting.

[0003] A search revealed that the announcement number is CN223042793U, and the name is "A Crushing and Screening Device for Contaminated Soil," which includes an installation bucket. Research and analysis showed that this device can separate sand, gravel, plant roots, and other impurities mixed in the soil, improving the cleanliness of the crushed soil and thus enhancing the integration of the drug with the soil and ensuring its remediation efficiency. However, it also has the following drawbacks to some extent.

[0004] For example, the crushing and screening device used for contaminated soil does not have the function of multi-stage screening of soil. In soil treatment, single screening cannot effectively distinguish impurities of different particle sizes. As a result, residual impurities will block the subsequent soil mixing and spreading equipment, affecting the continuity of the treatment process. Furthermore, it does not have the function of reprocessing the screened soil. Soil clumps that do not meet the crushing standard or soil particles containing fine impurities can only be collected manually and then crushed again or directly discarded. Manual secondary crushing not only increases labor and time costs, but also makes it difficult to ensure the uniformity of crushing. Direct disposal will result in the waste of soil resources. In order to solve the above technical problems, we have designed a soil crushing device with multi-stage filtration and screening. Utility Model Content

The return mechanism 13 includes a conveying cylinder 25, which is fixedly installed on the right side of the guide frame 28. By setting the guide frame 28, it is convenient to guide the screened soil into the conveying cylinder 25.

[0017] Please see Figure 1 and Figure 4 A screening screen 21 is embedded in the bottom of the inner cavity of the conveying pipe 2, and a turning plate 22 is fixedly installed on the surface of the first spiral shaft 5. By setting the turning plate 22, the soil can be turned over so that the soil falls from the conveying pipe 2 into the crushing frame 7. By setting the screening screen 21, large pieces of debris in the soil can be intercepted to prevent debris from entering the equipment.

[0018] Please see Figure 2 and Figure 3 A second motor 16 is fixedly installed on the left side of the fixed frame 15. The output end of the second motor 16 passes through the inner cavity of the fixed frame 15 and is fixedly connected to a screw 17. A threaded block 18 is threaded on the surface of the screw 17.

[0019] Please see Figure 2 and Figure 3 A cleaning brush 19 is fixedly connected to the front side of the threaded block 18. The front side of the cleaning brush 19 extends into the inner cavity of the screening frame 11. A cleaning scraper 20 is fixedly connected to the surface of the cleaning brush 19. By setting the cleaning brush 19, the surfaces of the screening plate 23 and the screening frame 11 can be cleaned. By setting the cleaning scraper 20, the soil accumulated on the surfaces of the screening plate 23 and the screening frame 11 can be scraped off.

[0020] Please see Figure 1 and Figure 2 The bottom of the conveying cylinder 25 is fixedly connected to a conveying motor 26. The output end of the conveying motor 26 passes through the inner cavity of the conveying cylinder 25 and is fixedly connected to a second spiral shaft 27. The top of the conveying cylinder 25 is connected to the feeding pipe 3.

[0021] Please see Figure 1and Figure 2 The screening frame 11 has a screening plate 23 fixedly connected to its inner cavity in the horizontal direction. A shielding plate 24 is installed on the rear side of the inner cavity of the screening frame 11. The bottom of the crushing frame 7 is connected to a discharge valve 10.

[0023] In operation, the user feeds soil into the conveying pipe 2 through the feeding pipe 3. The user then controls the drive motor 4, which conveys the soil via the first spiral shaft 5. During conveying, the first spiral shaft 5 agitates the soil via the flipping plate 22. The soil then passes through the screening screen 21 and falls into the crushing frame 7. The screening screen 21 intercepts large debris in the soil, and the first spiral shaft 5 conveys the intercepted debris to the receiving box 6 to prevent debris from remaining in the conveying pipe 2. The user then controls the first motor 8 to drive the crushing shaft 9 to crush the soil. After crushing, the user opens the discharge valve 10, allowing the soil to fall into the screening frame 11. The screening plate 23 in the screening frame 11 then performs the first screening of the soil. Afterwards, the screening frame 11 performs a second screening of the soil until it falls into the storage box 12. At the same time, the screening plate 23 and the screening frame 11 guide the screened soil into the conveying cylinder 25 through the guide frame 28. Then, the user operates the conveying motor 26 to drive the second spiral shaft 27 to convey the soil, so that the second spiral shaft 27 can transport the screened soil back into the feeding pipe 3, so that the soil can fall back into the crushing frame 7 for processing. When the screening plate 23 and the screening frame 11 are screening, the user can also operate the second motor 16 according to the screening situation, so that the second motor 16 can drive the cleaning scraper 20 and the cleaning brush 19 through the screw 17 and the threaded block 18 to clean the surface of the screening frame 11 and the screening plate 23, so as to prevent the soil from clogging the screening plate 23 and the screening frame 11.
