[0027] 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 embodiments described 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.

[0028] like Figure 1-Figure 3 As shown, the utility model provides a device for removing metal debris from a coal conveyor belt, comprising a gantry 1, a material picker 2 and a driving device 3.

[0029] Among them, the gantry 1 is set vertically upward on the ground, and the coal conveyor belt 4 passes through the doorway of the gantry 1; the cross-section of the conveyor belt 41 of the coal conveyor belt 4 is an arc-shaped structure, which is conducive to concentrating the coal and preventing the coal from being scattered during the transportation process. At the same time, it also increases the carrying capacity of the conveyor belt and improves the transportation efficiency.

[0030] The taker 2 is used to take the coal mixed with metal impurities from the coal conveyor belt 4 .

[0031] The driving device 3 is arranged on the gantry 1, and the gantry 1 is also provided with a metal sensor 11 facing the conveyor belt 41. After the metal sensor 11 senses that the coal transported on the conveyor belt 41 is mixed with metal; the driving device 3 drives the material picker 2 to move along the surface of the conveyor belt 41 for carrying the coal, so that the coal mixed with metal impurities enters the material picker 2, thereby completing the removal of metal impurities in the coal.

[0032] In order to enable the material collector to effectively obtain coal mixed with metal impurities, this embodiment discloses an embodiment of the material collector 2:

[0033] The reclaimer 2 includes two symmetrically arranged fan-shaped plates 21, and the straight edges on one side of the two fan-shaped plates 21 are connected by a baffle 22; the driving device 3 drives the reclaimer 2 to rotate along a plane perpendicular to the transmission direction of the coal conveyor belt 4.

[0034] This plane is staggered with the roller located below the conveyor belt 41 in the coal conveyor belt 4, and during the rotation process, the arc-shaped edge of the material picker 2 can fit with the surface of the conveyor belt 41 for carrying the coal. The conveyor belt 41 is made of rubber and can be deformed to increase the fit between the sector plate 21 and the conveyor belt 41, so that the coal doped with metal impurities can enter the material picker 2 to prevent the coal doped with metal impurities inside the material picker 2 from leaking out from the gap between the sector plate 21 and the conveyor belt 41, thereby realizing the separation of the coal doped with metal impurities from the conventional coal.

[0035] Furthermore, in this embodiment, the gantry 1 is provided with a discharge chute 5 on one side of the coal conveyor belt 4, and after the material picker 2 obtains the coal mixed with metal impurities, it continues to rotate toward the discharge chute 5; thereby, during the rotation of the material picker 2, the coal mixed with metal impurities located inside the material picker 2 moves toward the discharge chute 5 under the action of the baffle 2; and is finally left from the conveyor belt 41 and pushed into the discharge chute 5 by the baffle 2 for easy recovery and screening.

[0036] In this embodiment, the driving device 3 is preferably a rotating motor. If the material picker 2 rotates multiple times each time, the material picker 2 will obtain a lot of coal with normal composition; therefore, the rotating motor only rotates one circle each time, and the initial position of the material picker 2 is set to a horizontal position on the side of the lower chute 5.

[0037] In order to allow the material picker 2 to stay in this position, in this embodiment, the gantry 1 is provided with a support device 6 above the unloading chute, and the material picker 2 can pass through the support device 6 during the rotation process; and the support device 6 can support the material picker 2 so that the material picker 2 can maintain a horizontal state.

[0038] This embodiment discloses an embodiment of the support device 6, such as Figure 4 As shown:

[0039] The supporting device 6 includes a clamping groove 61 with an opening toward the material picker 2. Spring telescopic rods 62 are symmetrically and vertically provided on the inner side walls of the clamping groove 61 on both sides. Support blocks 63 are provided at the ends of the spring telescopic rods 62. The gap between the two support blocks 63 is smaller than the distance between the outer side walls of the two fan-shaped plates 21 of the material picker 2. The two support blocks 63 are used to support the material picker 2.

[0040] The distance between the inner side walls of the clamping groove 61 is greater than the distance between the outer side walls of the two fan-shaped plates 21 of the material picker 2, so that the material picker 2 can pass through the clamping groove 61 during the rotation process; and the position where the support block 63 contacts the support block 63 in the process of the material picker 2 passing through the clamping groove 61 is an upward inclined surface 64, so that the material picker 2 can squeeze the two support blocks 63 apart in the process of passing through the clamping groove 61.

[0041] Thus, the material picker 2 can pass through the two support blocks 63 from bottom to top; but cannot pass through the two support blocks 63 from top to bottom, so as to achieve the support effect on the material picker 2 and keep the material picker 2 in a horizontal state.

[0042] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
