[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the utility model discloses a silicon material conveying device, comprising an annular conveying belt 1, wherein the inner sides of two edges of the conveying belt 1 are respectively connected with annular chains 2.

[0032] A support rod 5 is provided on the chain plate 21 of the chain 2. A sheet-shaped connecting plate is provided at the end of the support rod 5 away from the chain plate 21. The connecting plate is connected to the conveyor belt 1. The chain 2 is connected to the conveyor belt 1 through the support rod 5 and the connecting plate, and a certain distance is left between the conveyor belt 1 and the chain 2. When the conveying distance of the conveyor belt 1 is long, in order to increase the support and stability of the conveyor belt 1, a gear (not shown in the figure) that meshes with the chain 2 can be rotatably arranged on the inner side of the movement track of the chain 2.

[0033] Sprockets 3 are respectively engaged on the two inner sides of the chains 2, and a transmission shaft 4 is coaxially connected between the two sprockets 3 on the corresponding sides of the two chains 2. The sprockets 3 are rotatably arranged on a conveying frame (not shown in the figure), one of the sprockets 3 is transmission-connected to a driving source, and the driving source drives the sprocket 3 to rotate, and the sprocket 3 drives the two chains 2 to perform horizontal circulation motion, and the conveyor belt 1 performs horizontal circulation motion accordingly.

[0034] A plurality of struts 18 are connected between the two chains 2. The plurality of struts 18 are arranged at equal intervals on the track of the chain 2. The struts 18 are arranged horizontally and parallel to the transmission shaft 4. The struts 18 move horizontally and cyclically synchronously with the chain 2 and the conveyor belt 1. A strip-shaped electromagnet 17 is arranged on the side wall of the strut 18 close to the conveyor belt 1. A busbar 6 whose shape matches the movement track of the strut 18 is arranged inside the arrangement area of ​​the strut 18. The electromagnet 17 is electrically connected to the busbar 6, and the busbar 6 can be fixed by a conveyor frame.

[0035] A plurality of tamping assemblies are arranged above the upper section of the conveyor belt 1 at equal intervals in the conveying direction of the conveyor belt 1. The material is conveyed on the upper section of the conveyor belt 1, and the tamping assemblies can flatten and tamp the material on the upper section of the conveyor belt 1. The tamping assemblies include a support plate 9, and a connecting rod 10 connected to the surrounding environment is provided on the top of the support plate 9, and the support plate 9 is fixed by the connecting rod 10. A plurality of tamping rods 7 are arranged below the support plate 9, and a pull wire 8 is connected between the top of the tamping rod 7 and the support plate 9. The tamping rod 7 has a certain weight and naturally droops and remains vertical without external force.

[0036] A receiving hopper is provided at the conveying end of the conveyor belt 1, and the receiving hopper is located outside the rotating part of the conveyor belt 1. The receiving hopper includes an inclined material plate 12, the higher end of which is located below the beginning of the lower section of the conveyor belt 1. Baffles 11 are provided on the edges of both sides of the material plate 12. The end of the baffle 11 close to the conveyor belt 1 is in an arc shape that matches the rotating section of the conveyor belt 1. The end of the baffle 11 and the higher end of the material plate 12 are both kept at a small distance from the conveyor belt 1. A metal detector 13 is provided at the lower end of the receiving hopper material plate 12, and the metal detector 13 detects whether the passing material contains metal objects.

[0037] A discharge assembly is provided below the lower section of the conveyor belt 1, and the discharge assembly discharges metal objects on the conveyor belt 1. The discharge assembly includes a discharge hopper 14, and the discharge hopper 14 covers the entire lower section of the conveyor belt 1. A plurality of vertically arranged mandrels 15 are provided in the discharge hopper 14, and the plurality of mandrels 15 are arranged in a matrix in the discharge hopper 14. A discharge rod 16 is hinged at the top of the mandrel 15, and the rotation axis of the discharge rod 16 is parallel to the transmission shaft 4. The top of the discharge rod 16 is spherical and tilted in a direction away from the beginning of the lower section of the conveyor belt 1. A torsion spring is provided between the discharge rod 16 and the mandrel 15, and the elastic force of the torsion spring drives the discharge rod 16 to swing so that the top of the discharge rod 16 remains in contact with the conveyor belt 1.

[0038] The rotation of the sprocket 3 drives the chain 2 and the conveyor belt 1 to move horizontally in a circular motion, and the electromagnet 17 on the inner side of the conveyor belt 1 moves horizontally in a circular motion synchronously therewith. When the conveyor belt 1 moves to the lower section, the electromagnet 17 is powered off, and otherwise the electromagnet 17 remains powered on. After the material enters the upper section of the conveyor belt 1, the circular motion of the conveyor belt 1 drives the material to move toward the end of the upper section of the conveyor belt 1. The metal objects in the material are adsorbed on the conveyor belt 1 by the electromagnet 17. The tamping assembly flattens the material to prevent the material from piling up, which causes the metal objects on the top of the material pile to be unable to be well adsorbed on the conveyor belt 1. When the material passes through the upper section of the conveyor belt 1 and enters the rotating section on the side of the receiving hopper, the material falls into the receiving hopper under the action of gravity. The metal objects are still adsorbed on the conveyor belt 1 by the electromagnet 17. The material slides to the lower end in the receiving hopper and passes through the metal detector 13 for metal object detection. When the metal objects on the conveyor belt 1 enter the lower section with the conveyor belt 1, the electromagnet 17 is powered off and no longer adsorbs the metal objects. The metal objects fall into the discharge hopper 14 under the action of gravity, and the discharge rod 16 that keeps in contact with the conveyor belt 1 will scrape off the metal objects that may still be attached to the surface of the conveyor belt 1.

[0039] The utility model realizes magnetic separation of materials in the process of conveying materials, separates metal objects from the materials, combines magnetic separation with the conveying step, improves working efficiency, and the materials after magnetic separation are also subjected to metal detection, so that the quality of the materials is controlled. The set tamping component can flatten the materials to avoid the accumulation of materials making it difficult for metal objects on the upper part of the material pile to be adsorbed, so that the metal objects can be better separated from the materials, thereby improving the magnetic separation effect of the materials.

[0040] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
