[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] Reference below Figure 1-Figure 4 A coal conveyor belt with impurity removal function according to an embodiment of the present invention is described.

[0032] The coal conveyor belt with impurity removal function according to the embodiment of the present invention comprises a coal conveyor body 1 , a belt, a suspension 3 and an impurity removal hook 4 .

[0033] The belt is rotatably arranged on the coal conveyor body 1, and the suspension 3 is arranged above the belt;

[0034] The debris removal hook 4 is connected to the suspension frame 3 through the chain 2, and the debris removal hook 4 is arranged adjacent to the belt so as to hook the impurities in the coal material.

[0035] The coal conveyor belt with impurity removal function of the embodiment of the present invention can hook out non-metallic impurities such as woven bags and plastics by setting the impurity removal hook 4, thereby avoiding the problem of coal machine blockage and coal shortage caused by coal flow entering the coal bunker of the coal washing plant. In addition, the impurity removal hook 4 is used to hook the impurities, and no large-scale point equipment is required. Therefore, the coal conveyor belt with impurity removal function has the advantages of low investment cost and good effect.

[0036] The coal conveyor belt with impurity removal function in the embodiment of the present invention has the advantages of simple structure, easy installation and low investment cost.

[0037] Furthermore, in the process of conveying the coal flow, the woven bags caught by the debris removal hook 4 can be manually removed after being accumulated for a certain period of time.

[0038] like Figure 1 and Figure 3 As shown, the impurity removing hook 4 includes a main body rod 41 and a plurality of hook bodies 42 disposed on the main body rod 41 . The hook bodies 42 are disposed on the main body rod 41 at intervals along the extending direction of the main body rod 41 so as to hook impurities from multiple directions.

[0039] The coal conveyor belt with impurity removal function in the embodiment of the present invention can remove impurities in multiple directions, especially soft impurities such as woven bags and plastics, by dividing the impurity removal hook 4 into a main rod 41 and a plurality of hook bodies 42 arranged on the main rod 41. The coal conveyor belt with impurity removal function in the embodiment of the present invention improves the thoroughness of impurity removal.

[0040] like Figure 1 and Figure 3 As shown, the lengths of the plurality of hooks 42 increase along the direction from the belt to the suspension 3 .

[0041] The coal conveyor belt with impurity removal function of the embodiment of the present invention increases the length of the plurality of hook bodies 42 along the direction from the belt to the suspension 3, so that each hook body 42 has a chance to hook and set impurities to prevent the impurities from being missed. Therefore, the coal conveyor belt with impurity removal function of the embodiment of the present invention improves the thoroughness of impurity removal.

[0042] like Figure 1 and Figure 3 As shown, the hook body 42 is a sickle-shaped hook. Thus, the stability of the hook body 42 hooking the impurities can be ensured, and the problem of falling off can be prevented during the movement of the coal flow.

[0043] There are multiple impurity removal hooks 4, and the multiple impurity removal hooks 4 are arranged at intervals along the width direction of the coal conveyor body 1. In this way, the problem of impurities being missed can be prevented. Furthermore, the coal conveyor belt with impurity removal function in the embodiment of the present invention further improves the adequacy of impurity removal.

[0044] A plurality of impurity removal hooks 4 are arranged at intervals along the length direction of the coal conveyor body 1. Thus, the problem of impurity leakage can be prevented. Furthermore, the coal conveyor belt with impurity removal function of the embodiment of the present invention further improves the adequacy of impurity removal.

[0045] The coal conveyor belt with impurity removal function in the embodiment of the present invention further includes a permanent magnetic cylinder, which is connected to the suspension 3 through a chain 2, and the magnetic cylinder is mounted on the belt. Thus, iron blocks in the coal flow can be removed. This further avoids the problem of iron blocks in the coal flow entering the coal bunker of the coal washing plant and damaging the conveying equipment.

[0046] like Figure 1 and Figure 2 As shown, the suspension 3 includes a portal frame 31 and a transverse top plate 32 arranged on the top of the portal frame 31 , the lower end of the portal frame 31 is connected to the coal conveyor body 1 , and the lower end of the transverse top plate 32 is fixed with a chain 2 .

[0047] The coal conveyor belt with impurity removal function of the embodiment of the present invention can provide tension support for the impurity removal hook 4 by dividing the suspension 3 into a portal frame 31 and a horizontal top plate 32. Therefore, the coal conveyor belt with impurity removal function has the advantage of simple structure.

[0048] like Figure 1 and Figure 4 As shown, the coal conveyor belt with impurity removal function in the embodiment of the present invention also includes an impurity turning mechanism 65 and support rods. The support rods are rotatably mounted on both sides of the width direction of the coal conveyor body 1. The impurity turning mechanism 65 is sleeved on the support rods, and the impurity turning mechanism 65 is located directly above the belt so as to turn over the impurities mixed in the coal flow to above the coal flow.

[0049] Optionally, the portal frame 31 can be telescopically arranged to adjust the inclination angle between the debris removing hook 4 and the belt, so that the debris removing hook 4 can be adjusted to find a better hooking effect.

[0050] The coal conveyor belt with impurity removal function of the embodiment of the present invention can turn the impurities buried under the coal flow to the surface of the coal flow through the impurity turning mechanism 65 and the support rod, and then use the impurity removal hook 4 to hook the impurities turned to the surface, so as to avoid the impurities pressed at the bottom of the coal flow from being missed. Therefore, the coal conveyor belt with impurity removal function of the embodiment of the present invention further improves the thoroughness of impurity removal.

[0051] like Figure 1 and Figure 4 As shown, there are multiple hook tooth rows, which are arranged on the cylinder sleeve 51 at intervals along the extension direction of the support rod, and two adjacent hook tooth rows are staggered along the axial direction of the cylinder sleeve 51.

[0052] The coal conveyor belt with impurity removal function of the embodiment of the present invention improves the thoroughness of turning over impurities by providing multiple hook tooth rows, which are spaced apart along the extension direction of the support rod on the cylinder sleeve 51. Therefore, the hook tooth row cooperates with the impurity removal hook 4 to further improve the thoroughness of impurity removal.

[0053] like Figure 1 and Figure 4 As shown, the hook teeth 52 include arc teeth and hook teeth, and the arc teeth and hook teeth form a V-shaped hook tooth group 52. Thus, the strength of the flip can be increased during rotation, thereby further improving the thoroughness of the impurity removal.

[0054] like Figure 1 As shown, the coal conveyor body 1 includes a driving assembly, an inclined section 12, and a front horizontal section 11 and a rear horizontal section 13 connected to the front and rear ends of the inclined section 12; the front horizontal section 11 is arranged corresponding to the higher end of the inclined section 12, the rear horizontal section 13 is arranged corresponding to the lower end of the inclined section 12, the turning mechanism 65 is arranged above the corresponding belt of the front horizontal section 11, the suspension 3 is arranged in the front horizontal section 11 or in the area below the inclined section 12, the debris removing hook 4 is arranged above the inclined section 12 through the chain 2, the turning mechanism 65 is arranged above the corresponding belt of the front horizontal section 11, and the front horizontal section 11 is arranged corresponding to the higher end of the inclined section 12.

[0055] In the coal conveyor belt conveyor with impurity removal function of the embodiment of the present invention, the impurity turning mechanism 65 is arranged above the corresponding belt of the front horizontal section 11, that is, the coal is turned first. Then, the impurity removal hook 4 is set above the inclined section 12 through the chain 2, and the larger coal blocks can roll down first, and the lighter impurities will float above the coal flow, and it is more convenient to hook the impurities with the impurity removal hook 4. Therefore, the coal conveyor belt conveyor with impurity removal function of the embodiment of the present invention has the advantage of further improving the impurity removal effect.
