DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 the workload, and have a 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 supporting structure 1, a track 2, a driving component 3, and a first adsorption component 4. The track 2 and the driving component 3 are fixedly connected to the supporting 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, and each first adsorption component 4 is conductively connected to the track 2. The driving 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 part 21 of the track 2 that carries positive electricity, and a second part 22 that carries negative electricity or is uncharged. When impurity separation is performed, each first adsorbent 4 is driven to slide along the track 2 by the driving component 3, and the soil carrying impurities passes through the intervals between each first adsorbent 4 at the first part 21. When the first adsorbent 4 is located on the first part 21, the first adsorbent 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 adsorbent 4; when the first adsorbent 4 adsorbed with impurities slides to the second part 22, the charge state on the first adsorbent 4 is the same as that of the second part 22 and cannot 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 part 22 and the first part 21 to complete the separation. Compared with manual separation, the device is used to separate soil and impurities. The separation is performed by using electrical 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 the workload, being more efficient and faster, and achieving better separation effect.

[0029] In a preferred implementation of this embodiment, a plurality of first adsorbents 4 are provided, and there is a gap between two adjacent first adsorbents 4. A plurality of second adsorbents 5 are also provided, and a second adsorbent 5 is provided between each two adjacent first adsorbents 4. Both ends of the second adsorbent 5 are respectively fixedly connected to the two adjacent first adsorbents 4, and the second adsorbent 5 between the two adjacent first adsorbents 4 is only connected to one first adsorbent 4.

Figure 5As shown in the figure, the second adsorbents on the left and right sides of the insulating connector 6 are respectively the left second adsorbent 5a and the right second adsorbent 5b, the first adsorbents on the left and right sides of the insulating adsorbent 5a are respectively the left first adsorbent 4a and the right first adsorbent 4b, one end of the left second adsorbent 5a and the right second adsorbent 5b are respectively fixedly connected to the insulating connector 6, one end of the left second adsorbent 5a is connected to the left first adsorbent 4a (conduction can be achieved through wires or other conductive devices), and the other end is not connected to the right first adsorbent 4b, and the right first adsorbent 4b is not connected. One end of the second adsorbent 5b is connected to the right first adsorbent 4b. When the left first adsorbent 4a slides to the first part 21, the electrical properties of the left second adsorbent 5a are the same as those of the first part 21, and impurities are adsorbed on the left first adsorbent 4a and the left second adsorbent 5a. When the left first adsorbent 4a slides to the second part 22, the impurities on the left first adsorbent 4a and the left second adsorbent 5a fall off. During this process, the charge on the left first adsorbent 4a and the left second adsorbent 5a will not be transferred to the right first adsorbent 4b and the right second adsorbent 5b.

[0031] In a preferred implementation of this embodiment, the track 2 is annular. Each first adsorption member 4 can move along the annular track 2 and pass through the first portion 21 and the second portion 22 of the track 2 multiple times to achieve continuous separation. The track 2 is preferably a runway-type track 2 and is preferably inclined, with one arc segment of the track 2 being higher than another arc segment, and the higher arc segment forming the second portion 22.

[0032] In a preferred embodiment of this embodiment, the first adsorbent 4 is rod-shaped, one end of the first adsorbent 4 is slidably connected to the track 2, each first adsorbent 4 is horizontally arranged and parallel to each other, the second adsorbent 5 is a wire, each second adsorbent 5 is perpendicular to the first adsorbent 4, and multiple second adsorbents 5 are arranged between two adjacent first adsorbents 4, and each second adsorbent 5 between two adjacent first adsorbents 4 is arranged in sequence along the length direction of the first adsorbent 4. The wire and the rod-shaped first adsorbent 4 form a mesh-like electrostatic adsorption structure, which further increases the adsorption area and makes the separation effect better. Among them, the end of the first adsorbent 4 is slidably connected to the track 2 through a sliding contact sheet 9, the sliding contact sheet 9 is a conductor, the sliding contact sheet 9 is slidably connected to the track 2, and the end of the first adsorbent 4 is fixedly connected to the sliding contact sheet 9; the end of the first adsorbent 4 away from the track 2 can be suspended, or can be slidably connected to other structures of insulating materials, or another track 2 can be set at the end of the first adsorbent 4 away from the track 2, and the first part 21 and the second part 22 on the two tracks 2 are the same length and corresponding in position.

[0033] It should be noted that, in addition to the rod-shaped first adsorption member 4 and the wire-shaped second adsorption member 5, the first adsorption member 4 and the second adsorption member 5 can also be replaced by various forms such as an elastic hollow plate with conductive properties, a soft screen, etc.

[0034] In a preferred implementation of this embodiment, an electrostatic generating device 8 is further included. The electrostatic generating device 8 is fixedly connected to the supporting structure 1. The electrostatic generating device 8 has a positive output terminal and a negative output terminal.

The electrostatic generating device 8 makes the first part 21 carry positive electricity and the second part 22 carry negative electricity. When the first adsorbent 4 and the second adsorbent 5 are connected to the first part 21, they carry positive electricity and can adsorb impurities. When the first adsorbent 4 and the second adsorbent 5 are connected to the second part 22, they carry negative electricity and can repel impurities carrying negative charges, so that the impurities can be separated more quickly.

[0035] In a preferred implementation of this embodiment, an electrostatic generating device 8 is also included. The electrostatic generating device 8 is fixedly connected to the supporting structure 1. The electrostatic generating device 8 has a positive output terminal, which is connected to the first part 21. The second part 22 is made of insulating material. The electrostatic generating device 8 makes the first part 21 carry positive electricity. When the first adsorbent 4 and the second adsorbent 5 are connected to the first part 21, they carry positive electricity and adsorb impurities. When the first adsorbent 4 and the second adsorbent 5 are connected to the second part 22, they are not charged and will not adsorb impurities. Impurities can be separated. The method of inputting only positive electricity to the first part 21 consumes less power than the method of inputting positive electricity and negative electricity to the first part 21 and the second part 22 respectively.

[0036] In a preferred implementation of this embodiment, a debris collection and storage device 7 is further included, and the debris collection and storage device 7 can collect impurities that fall off from the first adsorption member 4 and the second adsorption member 5.

[0037] In a preferred implementation of the present embodiment, the debris collection and storage device 7 includes a suction device 71 and a storage box 72. The suction device 71 and the storage box 72 are both fixedly connected to the support structure 1. The suction device 71 is in communication with the storage box 72. The debris capture port 712 of the suction device 71 faces the second portion 22. The suction device 71 can suck in impurities separated from the first adsorbent 4 and the second adsorbent 5, and store the impurities in the storage box 72. The suction device 71 includes a debris collection channel 711, a debris capture port 712 and a negative pressure fan 713. One end of the debris collection channel 711 is connected to the air suction port 7131 of the negative pressure fan 713, and the other end forms the debris capture port 712. The exhaust port 7132 of the negative pressure fan 713 is in communication with the storage box 72.

[0038] In order to improve the automation degree of the device and the effect of impurity removal, in a preferred implementation of the present embodiment, a soil impurity removal control system 10 and an impurity adsorption detection system are also included. The soil impurity removal control system is respectively connected to the drive assembly 3 and the suction device 71 by signals. The impurity adsorption detection system includes a first impurity adsorption detection sensor 101 and a second impurity adsorption detection sensor 102. The first impurity adsorption detection sensor 101 and the second impurity adsorption detection sensor 102 are respectively arranged above and below the second part 22 and are both connected to the soil impurity removal control system 10 by signals. The first impurity adsorption detection sensor 101 and the second impurity adsorption detection sensor 102 can respectively detect the cleanliness of the first adsorption member 4 and the second adsorption member 5 passing through the second part 22 before and after impurities are removed by the impurity collection and storage device 7, and can transmit the detection results to the soil impurity removal control system 10. The soil impurity removal control system 10 can control the rotation speed of the drive assembly 3 and the output power of the suction device 71 according to the detection results. Specifically, the soil impurity removal control system 10 is connected to the negative pressure fan 713 by signals.

[0039] It should be noted that, in addition to the suction device 71 and the storage box 72, the debris collection and storage device 7 provided by the present invention may also be provided with a dust bag or other devices with dust collection and removal functions under the second part 22 to collect impurities.

[0040] In a preferred implementation of this embodiment, the driving assembly 3 includes a motor 31 and a gear 32. The motor 31 is fixedly connected to the support structure 1, and the gear 32 is fixedly connected to the output shaft of the motor 31. A plurality of first adsorption members 4 form an adsorption structure, and the gear 32 is meshed with the adsorption structure. The gear 32 rotates under the drive of the motor 31, and drives the entire adsorption structure to move along the track 2. Among them, the motor 31 is connected to the soil impurity removal control system 10 by signal. In addition, in addition to the gear 32, a belt can be used to connect all the first adsorption members 4 in series, and the motor 31 can be connected to the belt transmission, and each first adsorption member 4 is driven to move along the track 2 by the rotation of the driving belt.

[0041] Specifically, during use, the motor 31 is turned on to make the first adsorption member 4 and the second adsorption member 5 slide along the track, and the debris collection and storage device 7 is turned on at the same time, and the soil carrying impurities is poured from the top of the first part 21. When the impurities carrying negative electricity in the soil slide to the first adsorption member 4 and the second adsorption member 5 of the first part 21, the impurities carrying negative electricity can be adsorbed on the first adsorption member 4 and the second adsorption member 5 carrying positive electricity. When the first adsorption member 4 and the second adsorption member 5 adsorbed with impurities move to the second part 22, since the second part 22 carries negative electricity or insulation, the impurities on the first adsorption member 4 and the second adsorption member 5 will fall off, and at this time, the suction device 71 can suck the impurities into the storage box 72. At the same time, the soil impurity removal control system 10 can adjust the moving speed of the first adsorption member 4 and the second adsorption member 5 and the output power of the suction device 71 according to the detection conditions of the debris adsorption detection system, so as to ensure the impurity removal effect.

[0042] The working principle of the soil impurity removal equipment provided by the present invention is: the impurities in the soil carry negative electricity. When the soil carrying impurities passes through the soil impurity removal equipment, the light impurities in the soil are separated by the attraction and repulsion between the positive and negative charges in the electric field and the gravity of the soil and the impurities themselves.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
