[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The purpose of the present invention is to provide a soil impurity removal device to solve the problems existing in the above-mentioned prior art, realize continuous operation processing of soil, reduce workload, and achieve better separation effect.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The present invention provides a soil impurity removal device, such as Figure 1-5 As shown, it includes: a support structure 1, a track 2, a drive component 3, and a first adsorption component 4. The track 2 and the drive component 3 are fixedly connected to the support structure 1. The track 2 includes a first part 21 and a second part 22. The first part 21 carries a positive charge, and the second part 22 carries a negative charge or is uncharged. The first part 21 is smoothly connected to the second part 22. Each first adsorption component 4 is slidably connected to the track 2 in turn. Each first adsorption component 4 is conductive with the track 2. The drive component 3 can drive each first adsorption component 4 to slide along the track 2.

[0028] The soil impurity removal equipment provided by the present invention has a first portion 21 of the track 2 that carries positive electricity, and a second portion 22 that carries negative electricity or is uncharged. When impurity separation is performed, each first adsorption member 4 is driven by the driving component 3 to slide along the track 2, and the soil carrying impurities is made to pass through the gaps between each first adsorption member 4 at the first portion 21. When the first adsorption member 4 is located on the first portion 21, the first adsorption member 4 is connected to the first track 2 and carries positive electricity. Since most of the light impurities in the soil (such as weeds, wood chips, plastic particles, etc.) carry negative electricity, these impurities can be adsorbed on the first adsorption member 4. When the first adsorption member 4 that is adsorbed with impurities slides to the second portion 22, the charge state on the first adsorption member 4 is the same as that of the second portion 22 and it is unable to adsorb impurities carrying negative electricity, and the impurities will fall off. Then, the impurities and soil are collected at the corresponding positions of the second portion 22 and the first portion 21, respectively, to complete the separation. Compared with manual separation, the device is used to separate soil and impurities. The separation is performed by using electric adsorption, which can continuously remove impurities in the soil as the soil continuously passes through the first adsorption component 4, thereby realizing continuous operation of the soil, reducing workload, being more efficient and faster, and achieving better separation effect.
