[0002] In modern society, with the acceleration of industrialization, the widespread development of agricultural activities and the continuous advancement of urbanization, soil pollution is becoming increasingly serious. Soil pollution not only leads to a decline in soil quality and affects the growth and yield of crops, but may also endanger human health and the balance of the ecosystem through the transmission of the food chain. Traditional soil remediation methods often focus on a single remediation technology, such as chemical remediation, physical remediation or biological remediation, which makes it difficult to achieve a comprehensive and efficient remediation effect. In the process of soil remediation and ecological restoration, the crushing of contaminated soil is one of the key steps. It helps to increase the contact area between the soil and the remediation agent and improve the remediation efficiency. However, the existing soil Most crushing devices can only complete the crushing function, and lack an effective mechanism to automatically and evenly add soil remediation agents during the crushing process, resulting in insufficient mixing of the remediation agent and the soil, affecting the uniformity and stability of the remediation effect. At the same time, the soil is often mixed with various impurities such as stones. Before soil remediation, the soil needs to be screened to remove these impurities to ensure that the remediation work is carried out on pure soil.

A tooth block is arranged on the outer surface of the toggle wheel 8, and the tooth block on the outer surface of the toggle wheel 8 is designed with missing teeth. A spring is connected between the material dropping plate 12 and the function plate 14, and the outer surface of the material dropping plate 12 fits the inner surface of the feed tube 11, the material shaking teeth 15 are evenly arranged at one end of the function plate 14, and a gap is left between the end of the function plate 14 where the material shaking teeth 15 are arranged and the opening of one end of the material dropping trough 13; The connecting gear 17 is meshed with the functional gear 18, and the adjacent connecting gears 17 are fixedly connected, the outer surface of the lower end of one side of the toggle tooth 20 is in contact with the upper end of the limit seat 19, and a spring is connected between the side surface of one end of the toggle tooth 20 that is in contact with the upper end of the limit seat 19 and the upper surface of the sliding plate 7, and the toggle tooth 20 is meshed with the functional gear 18; During normal use, firstly, a sufficient amount of powder repair agent is poured into the inside of the feed barrel 11, and then the hanger 1 is mounted on the power carrier and the drive motor 3 is started. At this time, the drive motor 3 is started to drive the two crushing wheels 2 to rotate at the same time through the first connecting chain 4. With the movement of the power carrier and the rotation of the crushing wheel 2, the crushing wheel 2 can crush the soil on the ground during the movement; During the crushing process, as the crushing wheel 2 rotates, the crushing wheel 2 on one side drives the toggle wheel 8 to rotate through the second connecting chain 9, and the toggle wheel 8 drives the sliding plate 7 to slide by the tooth block on the surface intermittently meshing with the tooth block at the lower end of the sliding plate 7, and then the sliding plate 7 drives the dividing plate 6 to slide through the driving rod 10, and the dividing plate 6 slides relative to the dividing box 5 and drives the sliding plate 7 to reset in the opposite direction under the action of the spring between the dividing box 5, so that the dividing plate 6 and the sliding plate 7 can intermittently reciprocate. At this time, with the reciprocating sliding of the dividing plate 6 and the misalignment and overlap of the holes on the surface of the dividing plate 6 and the dividing box 5, the powder repair agent above the dividing plate 6 in the dividing box 5 is gradually shaken down to between the two crushing wheels 2 and fully mixed with the soil; During the forward sliding of the sliding plate 7, the toggle tooth 20, under the support of the upper end of the limit seat 19, enables the sliding plate 7 to mesh with the functional gear 18 through the toggle tooth 20 at the upper end to drive the functional gear 18 to rotate. The functional gear 18 drives the blanking plate 12 to rotate through the meshing with the driving gear 16 through the connecting gear 17. During the rotation of the blanking plate 12, the powder repairing agent can enter the blanking trough 13 through the gap between the functional plate 14 and the blanking trough 13. At the same time, the functional plate 14 drives the shaking tooth 15 to rotate under the support of the spring between the blanking plate 12 to scrape the material inside the upper feeding barrel 11, so that the powder repairing agent will not pile up and cause powder The material body cannot fall normally, and as the blanking tray 12 rotates, the outer surface of the functional plate 14 is squeezed and rotated, so that the functional plate 14 rotates and enters the blanking trough 13 without blocking the normal rotation of the blanking tray 12. When the blanking trough 13 filled with powder repair agent opens downward toward the dividing plate 6, the powder repair agent in the blanking trough 13 falls into the upper surface of the dividing plate 6 in the dividing box 5 through the lower end of the feeding cylinder 11, completing the blanking. When the sliding plate 7 slides in the opposite direction, the toggle tooth 20 is squeezed by the functional gear 18. At this time, the limit seat 19 does not support the toggle tooth 20, so that the toggle tooth 20 rotates to let the functional gear 18 pass, thereby achieving the purpose of driving the blanking tray 12 to rotate in one direction.

The screening gear 27 drives the soil-scooping cylinder 22 to rotate by meshing with the connecting tooth plate 25. The lower end of the soil-scooping cylinder 22 rotates to the ground to shovel soil into the interior of the soil-scooping cylinder 22. After entering the soil-scooping cylinder 22, the fully crushed soil leaks out along the holes on the surface of the soil-scooping cylinder 22 during the rotation process, while stones and inadequately crushed agglomerated soil gradually enter the inner layer of the spiral soil-scooping cylinder 22 as the soil-scooping cylinder 22 rotates, until the stones and inadequately crushed agglomerated soil enter the interior of the central rod 21 through the upper end of the guide groove 23 and are discharged downward along the guide groove 23 and the outlet plate 24 to both sides of the hanger 1 to wait for collection and cleaning.
