Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation, in particular to a dust-free coal raw material transportation device. Background Art

[0002] In industrial production, when coal is transported on a conveyor belt, the coal will fall from the high conveyor belt or hopper onto the conveyor belt below. When the coal falls or is subsequently transported on the conveyor belt, the collision between adjacent coals or the vibration between the conveyor belt will generate dust, and the dust will fly or accumulate on the conveyor belt. When the running conveyor belt transports to the end of one end, the dust accumulated on the conveyor belt will fall and fly. Therefore, the dust falling on the conveyor belt needs to be collected and processed centrally. Utility Model Content

The clamping mechanism contacts the conveyor belt located above the upper support frame. When the conveyor belt passes through the clamping mechanism, it is deformed and gathered inward. The dust-proof mechanism is used to shield the conveyor belt and collect dust generated by the medium on the conveyor belt.

[0010] In the above technical solution, the clamping mechanism is used to gather the conveyor belt and deform it, so that the coal raw materials are moved closer to the middle of the conveyor belt, while preventing dust from overflowing to both sides of the conveyor belt.

[0042] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0043] like Figures 1 to 4 As shown, this embodiment provides a dust-free coal raw material conveying device, comprising:

[0044] The conveyor frame 1 includes an upper support frame and a lower support frame. The upper support frame is provided with a plurality of rollers 11 and a driving mechanism. The rollers 11 are connected to the driving mechanism. The upper support frame is also provided with a clamping mechanism.

[0045] The conveyor belt 2 is wound on two rollers 11 and rolls along the upper support frame and the lower support frame;

[0046] A dust-proof mechanism, which is arranged on the outside of the conveyor belt 2;

[0047] Among them, a feeding device is provided on the side of the conveying frame 1 close to the clamping mechanism, and the feeding device is used to feed the medium toward the conveyor belt 2 above the clamping mechanism. The clamping mechanism contacts the conveyor belt 2 located above the upper support frame. When the conveyor belt 2 passes through the clamping mechanism, it is deformed and gathers inward. The dust-proof mechanism is used to shield the conveyor belt 2 and collect the dust generated by the medium on the conveyor belt 2.

[0048] like Figure 4 and Figure 6 As shown, the conveyor belt 2 is provided with a plurality of cutouts 21 at equal intervals along the length direction.

[0049] like Figure 1 and Figure 2 As shown, the clamping mechanism includes a limit member 31, a connecting rod and a plurality of rollers 32. The limit member 31 includes a limit frame and wing plates arranged on both sides of the limit frame. The limit frame is fixedly connected to the upper support frame, and the two wing plates face the two sides of the upper support frame respectively. The connecting rod is fixedly connected along the path of the limit member 31, and the roller 32 is rotatably connected to the connecting rod. The incision 21 is located at the connection between the wing plate and the limit frame.

[0050] like Figure 1 and Figure 2 As shown, the clamping mechanism is located in the middle of the conveying frame 1 , and the two rollers 11 are respectively located at the two ends of the conveying frame 1 .

[0051] like Figures 1 to 6 As shown, a plurality of pushing members 5 are arranged between the roller 11 and the clamping mechanism, the pushing members 5 are transmission-connected to the driving mechanism, the pushing members 5 are used to contact the bottom surface of the conveyor belt 2 located on the upper support frame, and the pushing members 5 are located on the side of the incision 21 close to the outside.

[0052] Specifically, the conveyor frame 1 includes an upper support frame and a lower support frame, the lower support frame is used to support the whole, the roller 11 is arranged on the upper support frame, and the lower support frame is responsible for overall support. The conveyor belt 2 is transported and transmitted along the roller 11 above the upper support frame and the lower support frame. The limit members 31 are arranged in a linear array equidistantly in the middle position of the upper support frame, and there is a distance between the limit members 31 and the rollers 11. The limit members 31 are in a ladder-like structure, the connecting rod is arranged along the path of the limit members 31, and the rollers 32 are rotatably connected to the connecting rod.

[0053] Discharging process: After the coal raw materials are collected, they are first stored in the feeding equipment, and the feeding equipment feeds the coal raw materials to the conveyor belt 2. Preferably, the feeding position is located above the clamping mechanism, or it can be on the side away from the dust prevention mechanism. The movement direction of the conveyor belt 2 should be toward the dust prevention mechanism. The conveyor belt 2 is located at the limit piece 31. Due to the limitation of the roller 32 and the ladder-shaped limit piece 31, the two sides of the flexible conveyor belt 2 in the width direction will move inward, and the coal raw materials at this position will be gathered in the middle of the conveyor belt 2. At the same time, because the opening position of the incision 21 is located at the connection between the wing plate and the limit piece 31, the two sides of the conveyor belt 2 at the limit piece 31 are in a gathered state, and the flexible conveyor belt 2 will fold at the incision 21 and close the incision 21 to prevent the coal raw materials from falling.

[0054] When the coal raw material moves with the conveyor belt 2 and leaves the limit piece 31, the conveyor belt 2 gradually returns to a flat state, and the conveyor belt 2 that returns to a flat state will be partially lifted up by the pushing piece 5 below. The pushing piece 5 is located on the side of the incision 21 close to the outside world. Therefore, the pushing piece 5 will form a height difference between one side of the incision 21 and the middle of the conveyor belt 2, and the two sides of the incision 21 are high and low to form a gap, and dust can fall downward.

[0055] like Figure 1 and Figure 2 As shown, the driving mechanism is used to drive the pushing member 5 to rotate, and the rotation radius of the pushing member 5 is higher than the height of the conveyor belt 2 located on the upper support frame.

[0056] like Figure 1 and Figure 2 As shown, the push member 5 is a cam structure, an elliptical structure or a diamond structure.

[0057] Specifically, the height of the pushing member 5 should be higher than the height of the conveyor belt 2 so as to raise one side of the cutout 21 to form a notch. It should be noted that after the cutout 21 is deformed to form a notch, the height of the notch should be smaller than the diameter of the coal raw material.

[0058] like Figure 2 and Figure 7 As shown, the dustproof mechanism includes a shield shell 41 and a blanking plate 42. The shield shell 41 is used to shield the conveyor belt 2 located between the clamping mechanism and the pushing member 5. The blanking plate 42 is located below the conveyor belt 2 on one side of the pushing member 5 and is connected to the inner wall of the shield shell 41.

[0059] like Figure 2 As shown, the blanking plate 42 is tilted upward away from the connection with the shield shell 41 , and a dust collecting bin is detachably connected to one side of the shield shell 41 facing the blanking plate 42 , and the inlet of the dust collecting bin is connected to the channel of the blanking plate 42 .

[0060] like Figure 3 , Figure 5 and Figure 7 As shown, the dust prevention mechanism also includes a cleaning brush, on which a baffle 43 and a handle are provided, the handle is connected to the top inner wall of the mask shell 41, the baffle 43 is connected to the handle and a plurality of bristles are provided on the bottom surface, the cleaning brush is located above the conveyor belt 2, the baffle 43 is in contact with the conveyor belt 2, the baffle 43 is in a V-shaped structure, the lateral length of the baffle 43 is greater than the width of the conveyor belt 2, and the middle height of the baffle 43 is lower than the heights on both sides.

[0061] Specifically, the shield shell 41 can effectively prevent dust from flying during the transportation of coal raw materials. The blanking plate 42 is located below the upper conveyor belt 2, that is, below the two pushing members 5, and is used to receive the dust falling from the incision 21. Preferably, there is an inclined surface on the blanking plate 42 to naturally drop the dust into the dust collecting bin for collection.

[0062] The baffle 43 is arranged near the end of the moving direction of the conveyor belt 2 and is located above the conveyor belt 2. The baffle 43 has a V-shaped structure and bristles that contact the conveyor belt 2 are arranged at the bottom. As mentioned above, the conveyor belt 2 located at the limit member 31 can effectively gather the coal raw materials to the middle. The baffle 43 has a V-shape and the middle height is lower than the height on both sides. The two sides of the baffle 43 can also effectively gather the coal raw materials to the middle. At the same time, as the conveyor belt 2 is transported, the coal raw materials accumulated at the baffle 43 overflow along the lower middle part and leave the conveyor belt 2 to complete the transportation. In addition, the bristles at the bottom of the baffle 43 effectively block the continued movement of dust on the conveyor belt 2. The bristles will push the dust here, and when one group of incisions 21 is lifted up by the pushing member 5 and moves to the baffle 43 position, the accumulated dust will fall along the notch to the blanking plate 42, completing the dust removal work of the conveyor belt 2.

[0063] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
