Description

Technical Field

[0001] This utility model relates to the field of anti-dropping technology for belt conveyor heads, and in particular to an anti-dropping side guard for belt conveyor heads equipped with five belts. Background Technology

[0002] The conveyor head of the batching room in the sintering plant is a key node for material conveying. Located at the end of the conveyor, it connects the batching process with subsequent processes. Its core function is to transport the mixed materials such as iron ore powder, fuel, and quicklime prepared in proportion in the batching room to the conveyor head via a drive drum and belt, and then transfer them to the next stage of equipment via the unloading device.

[0003] In daily work, it has been found that in the existing sintering plant, the material in the batching room used for the belt conveyor often falls off the belt conveyor head due to multiple factors. For example, the material at the edge slides outward due to loss of support, and the vibration of transportation causes the material to move to both sides. These scattered materials not only cause waste of raw materials, but also require frequent cleaning by dedicated personnel, increasing the cleaning burden on workers. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art where materials fall off the conveyor head due to multiple factors, such as edge materials slipping outwards due to loss of support, and transportation vibrations causing materials to move to both sides. These scattered materials not only cause waste of raw materials, but also require frequent cleaning by dedicated personnel, increasing the cleaning burden on workers. Therefore, this utility model proposes a five-belt conveyor head anti-drop edge guard.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a five-belt conveyor head anti-drop edge guard, comprising two mounting plates installed on the conveyor frame, the two mounting plates being located on both sides of the conveyor head. The surface of each mounting plate is provided with a protective device, the protective device including a slide rail and an air supply assembly. The slide rail is fixed to the surface of the mounting plate, and an adjusting seat is slidably connected to the surface of the slide rail. A blower body is rotatably connected to the inner wall of the adjusting seat. An air inlet is provided on the surface of the blower body, and a rotary joint is rotatably connected to the inner wall of the air inlet. The air supply assembly is installed on the outer surface of the conveyor frame and is used to connect with the rotary joint to supply air to the blower body. The surface of the mounting plate is provided with an adjusting assembly, which includes a height adjusting part and an angle adjusting part. The height adjusting part is used to control the position of the adjusting seat, and the angle adjusting part is used to control the angle of the blower body. Through the above components, during material drop, the air supply assembly sequentially delivers gas to the rotary joint and the air inlet, and the blower body blows out, which can blow material from the edge of the belt towards the middle of the belt, reducing the phenomenon of material falling off the conveyor head.

[0006] Preferably, the angle adjustment unit includes two guide rods fixed to the surface of the adjustment seat. A slide is slidably connected to the surface of the guide rods. Two racks are fixedly connected to the surface of the slide. A gear is fixedly connected to the surface of the blow knife body. The racks mesh with the gears. A rotating screw is rotatably connected to the surface of the adjustment seat. The rotating screw is threadedly connected to the inner wall of the racks. Through the above components, when adjusting the angle, rotating the rotating screw can control the movement of the slide and racks. When the racks move, they cooperate with the gears to drive the blow knife body to rotate, thereby adjusting the blowing angle.

[0007] Preferably, the height adjustment unit includes a control screw that is rotatably connected to the inner wall of the mounting plate. The control screw is threadedly connected to the inner wall of the adjustment seat. By rotating the control screw, the adjustment seat can be moved on the slide rail, thereby adjusting the height of the blow knife body.

[0008] Preferably, the gas delivery assembly includes a spiral fan, with an inlet pipe and an outlet pipe fixedly connected to the inlet and outlet ends of the spiral fan, respectively. A connector is fixedly connected to the surface of the outlet pipe, and two connecting pipes are installed on the surface of the connector. The other ends of the two connecting pipes are fixedly connected to the surface of the rotary joint. By turning on the spiral fan through the above components, the spiral fan can draw in air through the inlet pipe, and then deliver the gas to the two connecting pipes through the outlet pipe and the connector. The connecting pipes deliver the gas to the rotary joint, the air inlet, and the blower body.

[0009] Preferably, the inner wall of the air intake pipe is threaded with a filter cover, and the surface of the filter cover is provided with a cleaning section.

[0010] Preferably, the cleaning unit includes a rotating ring rotatably connected to the surface of the filter cover, and a cleaning brush is fixedly connected to the surface of the rotating ring. Through the above-mentioned components, the rotating ring can be rotated, and the rotating ring can drive the cleaning brush to rotate, thereby cleaning the dust accumulated on the surface of the filter cover.

[0011] Preferably, the filter cover is made of stainless steel.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a protective device, the air supply component supplies air to the blower body through the rotary joint and air inlet. The blower body blows air towards the edge of the belt, which can actively blow the material that has deviated to both sides back to the middle of the belt, reducing the material falling at the machine head from the source and greatly reducing material waste. In addition, the height adjustment part and angle adjustment part in the adjustment component can flexibly adjust the distance between the blower body and the belt and the blowing angle, improving the overall flexibility.

[0013] In this invention, the stainless steel filter cover can filter impurities in the intake air and prevent the blower body from clogging; the rotating ring drives the cleaning brush to rotate, which can quickly clean the dust on the surface of the filter cover. Attached Figure Description

An air inlet 26 is provided on the surface of the blow knife body 22. A rotary joint 27 is rotatably connected to the inner wall of the air inlet 26. The air supply assembly 24 is installed on the outer surface of the belt conveyor frame and is used to connect with the rotary joint 27 to supply air to the blow knife body 22. An adjusting assembly 23 is provided on the surface of the mounting plate 1. The adjusting assembly 23 includes a height adjusting part and an angle adjusting part. The height adjusting part is used to control the position of the adjusting seat 25, and the angle adjusting part is used to control the angle of the blow knife body 22.

[0018] In this implementation plan: when releasing material, the gas is sequentially delivered to the rotary joint 27 and the air inlet 26 through the gas conveying component 24, and blown out by the blower body 22, which can blow the material on the edge of the belt towards the middle of the belt, reducing the phenomenon of material falling off at the head of the belt conveyor.

[0019] Specifically, the angle adjustment unit includes two guide rods 234 fixed on the surface of the adjustment seat 25, a slide 233 slidably connected to the surface of the guide rods 234, two racks 235 fixedly connected to the surface of the slide 233, a gear 236 fixedly connected to the surface of the blow knife body 22, the racks 235 meshing with the gears 236, and a rotating screw 232 rotatably connected to the surface of the adjustment seat 25, the rotating screw 232 being threadedly connected to the inner wall of the racks 235.

[0020] In this implementation scheme: when adjusting the angle, rotating the rotating screw 232 can control the movement of the slide 233 and the rack 235. When the rack 235 moves, it cooperates with the gear 236 to drive the blow knife body 22 to rotate, thereby adjusting the blowing angle.

[0021] Specifically, the height adjustment unit includes a control screw 231 that is rotatably connected to the inner wall of the mounting plate 1, and the control screw 231 is threadedly connected to the inner wall of the adjustment seat 25.

[0022] In this embodiment: rotating the control screw 231 can drive the adjusting seat 25 to move on the slide rail 21, thereby adjusting the height of the blow knife body 22.

[0023] Specifically, the air supply assembly 24 includes a spiral fan 241. The input end and output end of the spiral fan 241 are respectively fixedly connected to an air inlet pipe 243 and an air outlet pipe 242. A connector 244 is fixedly connected to the surface of the air outlet pipe 242. Two connecting pipes 245 are installed on the surface of the connector 244.

A cleaning brush 248 is fixedly connected to the surface of the rotating ring 247.

[0024] In this implementation scheme: when the spiral fan 241 is turned on, the spiral fan 241 can draw in air through the air inlet pipe 243, and then deliver the air to two connecting pipes 245 through the air outlet pipe 242 and the connector 244 respectively. The connecting pipes 245 deliver the air to the rotary joint 27, the air inlet 26 and the blower body 22. During cleaning, the rotating ring 247 can be rotated, which can drive the cleaning brush 248 to rotate, thereby cleaning the dust accumulated on the surface of the filter cover 246.

[0025] Working principle: During operation, the spiral blower 241 is turned on. The spiral blower 241 draws in air through the inlet pipe 243. The filter hood 246 filters impurities from the gas. The gas is then delivered to two connecting pipes 245 via the outlet pipe 242 and connector 244. The connecting pipes 245 deliver the gas to the rotary joint 27, the inlet 26, and the blower body 22. The blower body 22 blows the gas out, directing material moving towards the sides of the conveyor belt towards the center of the belt, reducing material loss. The angle and position of the blower body 22 can be adjusted as needed. When rotating the control screw 231, the control screw 231 can drive the adjusting seat 25 to move on the slide rail 21, thereby adjusting the height of the blow knife body 22. Rotating the rotating screw 232 can control the movement of the slide 233 and the rack 235. When the rack 235 moves, it cooperates with the gear 236 to drive the blow knife body 22 to rotate, adjusting the blowing angle. When it is necessary to clean the dust on the filter cover 246, the rotating ring 247 can be rotated, which can drive the cleaning brush 248 to rotate and clean the dust on the filter cover 246.
