Description

Technical Field

[0001] This utility model relates to the field of dust prevention technology, and in particular to a belt conveyor device for loading and unloading stone materials with an adjustable dust cover. Background Technology

[0002] Stone materials refer to granular or blocky materials formed from natural rocks through mining, crushing, screening, or processing. They are mainly used in construction, road, and water conservancy projects. Based on their source, they can be divided into natural stone materials (such as granite, limestone, and basalt) and artificial stone materials (such as recycled aggregates). Based on particle size, they are divided into coarse aggregates (particle size > 4.75mm, such as crushed stone and pebbles) and fine aggregates (such as river sand and manufactured sand).

[0003] In the existing technology, when loading and unloading stones, belt conveyors are used to transport the stones to loading and unloading vehicles. During the process of transporting stones by belt conveyors, dust is easily generated at the end of the belt conveyor. Dust covers are usually installed at the end of the belt conveyor. However, the dust protection effect of existing dust covers is relatively average. When there is a lot of dust on the stones, they cannot play a good dust protection role, resulting in poor performance of the dust covers. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that when loading and unloading stones, belt conveyors are used to transport the stones to loading and unloading vehicles. During the process of transporting stones by belt conveyors, dust is easily generated at the end of the belt conveyor. Dust covers are usually installed at the end of the belt conveyor. However, the dust protection effect of existing dust covers is relatively poor. When there is a lot of dust on the stones, they cannot play a good dust protection role, resulting in poor performance of the dust covers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a belt conveyor device for loading and unloading stone materials with an adjustable dust cover, comprising: a belt conveyor, and further comprising:

[0006] Two fixed plates are fixedly connected to opposite sides of the belt conveyor near the top. The top of the fixed plates is provided with a sliding groove, and U-shaped strips are slidably connected inside the two sliding grooves. Dust cover bodies are fixedly connected to opposite sides of the U-shaped strips.

[0007] A dust collection mechanism is disposed above one of the dust cover bodies. The dust collection mechanism includes multiple diversion pipes II. The outer surfaces of the multiple diversion pipes II are fixedly connected at equal intervals to the top of one of the dust cover bodies. One end of the multiple diversion pipes II is fixedly connected to a guide pipe II. One end of the guide pipe II is fixedly connected to a U-shaped pipe. A filter box is fixedly connected to the top of one of the dust cover bodies. The filter box is fixedly connected to the U-shaped pipe. A fan is fixedly connected to one side of the filter box. The exhaust end of the fan extends into the interior of the filter box.

[0008] The spray mechanism is located above another of the dust cover bodies.

[0009] Preferably, the top of the filter box has two filter frames slidably connected, and the top of each filter frame has a handle fixedly connected.

[0010] Preferably, the other end of the second diversion pipe is fixedly connected to an air hood, and the multiple air hoods, multiple second diversion pipes, second guide pipes, U-shaped pipes and filter boxes are interconnected.

[0011] Preferably, the spraying mechanism includes multiple diversion pipes, the outer surfaces of which are fixedly connected at equal intervals to the top of another dust cover body, and one end of each diversion pipe is fixedly connected to an atomizing nozzle.

[0012] Preferably, the other end of the plurality of diverter pipes is fixedly connected to a guide pipe, and the guide pipe, the plurality of diverter pipes, and the plurality of atomizing nozzles are interconnected.

[0013] Preferably, a water pump is fixedly connected to the top of another dust cover body, the discharge end of the water pump is fixedly connected to the outer surface of the guide pipe, and the suction end of the water pump is fixedly connected to a suction pipe.

[0014] Preferably, a guide rod is fixedly connected to the opposite side of the inner wall of the groove, and the guide rod is slidably connected to the U-shaped strip.

[0015] Preferably, the top of the fixing plate is provided with a plurality of limiting holes at equal intervals, and the opposite sides of the U-shaped strip are fixedly connected to limiting blocks. The top of the limiting blocks is threaded with a screw, and one end of the screw is movably connected to the inside of one of the limiting holes.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. This utility model controls the water pump to start via a controller, drawing water from the water source through a pumping pipe. The water is then sprayed onto the surface of the stones being transported on the belt conveyor through a first guide pipe, a second diversion pipe, and an atomizing nozzle, wetting the dust on the stone surface and reducing the amount of dust generated during subsequent loading and unloading of the stones into the loading and unloading truck. Simultaneously, the controller also controls the exhaust fan to start, drawing air into the filter box. External air passes through an exhaust hood, a second diversion pipe, a second guide pipe, and a U-shaped pipe into the filter box, drawing in the dust generated when the stones fall into the loading and unloading truck. The dust is then filtered through a filter frame, and the filtered air is discharged through the exhaust fan. In this way, the combined spraying and dust collection mechanisms reduce the amount of dust generated during stone loading and unloading, thereby improving the effectiveness of the dust cover.

[0018] 2. In this utility model, by manually rotating the screw upwards, it disengages from the inside of the limiting hole, releasing the limiting block and the U-shaped strip. At this time, the dust cover body can be pushed, causing the U-shaped strip to slide to one side along the outer surface of the guide rod, adjusting the dust cover body near the end of the belt conveyor to a suitable distance, and moving the dust collection mechanism to a suitable position. In this way, when the stones conveyed by the belt conveyor fall into the loading and unloading vehicle and generate dust, the dust collection mechanism can easily absorb the dust generated by the falling stones, thereby avoiding large-scale dust pollution.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figure 1-4 As shown, this utility model provides a stone loading and unloading belt conveyor device with an adjustable dust cover, including: a belt conveyor 1, and two fixing plates 2, respectively fixedly connected to opposite sides of the belt conveyor 1 near the top. The top of the fixing plates 2 has a sliding groove 206, and U-shaped strips 201 are slidably connected inside the two sliding grooves 206. Dust cover bodies 202 are fixedly connected to opposite sides of the U-shaped strips 201. A dust suction mechanism is disposed above one of the dust cover bodies 202, and the dust suction mechanism includes multiple diversion pipes 4. The outer surface is fixedly connected at equal intervals to the top of one of the dust cover bodies 202. One end of the multiple diversion pipes 4 is fixedly connected to the guide pipe 401, and one end of the guide pipe 401 is fixedly connected to the U-shaped pipe 402. The top of one of the dust cover bodies 202 is fixedly connected to the filter box 404, which is fixedly connected to the U-shaped pipe 402. One side of the filter box 404 is fixedly connected to the exhaust fan 405, and the exhaust end of the exhaust fan 405 extends into the interior of the filter box 404. The spray mechanism is located above another dust cover body 202.

[0028] Furthermore, such as Figure 1-4 As shown, two filter frames 406 are slidably connected to the top of the filter box 404. A handle 407 is fixedly connected to the top of the filter frame 406. The filter frame 406 is designed to facilitate the filtration of dust, and the handle 407 is designed to facilitate the removal of the filter frame 406 for cleaning or replacement of the dust filtered by the filter frame 406.

[0029] Furthermore, such as Figure 1-4 As shown, the other end of the diversion pipe 4 is fixedly connected to the air hood 403. The multiple air hoods 403, multiple diversion pipes 4, the guide pipe 401, the U-shaped pipe 402 and the filter box 404 are connected to each other, so that the outside gas enters the interior of the filter box 404 by passing through the air hood 403, the diversion pipe 4, the guide pipe 401 and the U-shaped pipe 402 in sequence.

[0030] Furthermore, such as Figure 1-4 As shown, the spraying mechanism includes multiple diversion pipes 3. The outer surfaces of the multiple diversion pipes 3 are fixedly connected at equal intervals to the top of another dust cover body 202. One end of the diversion pipe 3 is fixedly connected to an atomizing nozzle 304. Through the setting of the atomizing nozzle 304, water can be sprayed out in an atomized state, which can play a certain dust reduction effect and wet the dust on the surface of the stone.

[0031] Furthermore, such as Figure 1-4 As shown, the other end of the multiple diversion pipes 3 is fixedly connected to the guide pipe 301. The guide pipe 301, the multiple diversion pipes 3 and the multiple atomizing nozzles 304 are connected. With the above arrangement, water can pass through the guide pipe 301, the diversion pipes 3 and the atomizing nozzles 304 in sequence and be sprayed onto the surface of the stone conveyed on the belt conveyor 1.

[0032] Furthermore, such as Figure 1-4 As shown, a water pump 302 is fixedly connected to the top of another dust cover body 202. The discharge end of the water pump 302 is fixedly connected to the outer surface of the guide pipe 301, and the suction end of the water pump 302 is fixedly connected to the suction pipe 303. The water pump 302 is started by the controller, so that it draws water from the water source through the suction pipe 303 and delivers the water to the guide pipe 301.

[0033] Furthermore, such as Figure 1-4 As shown, a guide rod 207 is fixedly connected to the opposite side of the inner wall of the slide groove 206. The guide rod 207 is slidably connected to the U-shaped strip 201. With the above arrangement, when the dust cover body 202 is pushed, the U-shaped strip 201 can slide to one side along the outer surface of the guide rod 207.

[0034] Furthermore, such as Figure 1-4 As shown, the top of the fixed plate 2 is provided with multiple limiting holes 205 at equal intervals. Each side of the U-shaped strip 201 is fixedly connected to a limiting block 203. The top of the limiting block 203 is threaded with a screw 204. One end of the screw 204 is movably connected to the inside of one of the limiting holes 205. By rotating the screw 204 by hand, it can be rotated upward and disengaged from the inside of the limiting hole 205, thus releasing the limiting of the limiting block 203 and the U-shaped strip 201.

[0035] Working principle: In use, the screw 204 is rotated by hand to rotate it upwards, disengaging it from the limiting hole 205 and releasing the limiting block 203 and U-shaped strip 201. At this time, the dust cover body 202 can be pushed, causing the U-shaped strip 201 to slide to one side along the outer surface of the guide rod 207, adjusting the dust cover body 202 near the end of the belt conveyor 1 to a suitable distance, and moving the dust collection mechanism to a suitable position. This way, when the stones conveyed by the belt conveyor 1 fall into the loading and unloading vehicle, generating dust, the dust collection mechanism can easily absorb the dust generated by the falling stones, thus avoiding large-scale dust pollution. Conversely, when this device is not needed, adjusting the U-shaped strip 201 and dust cover body 202 to a position closer to the middle of the belt conveyor 1 can reduce the space occupied by this device. By connecting the water pipe 303 to a water source and controlling the water pump 302 to start via the controller, the dust collection mechanism can be activated. Water is drawn from the water source through the water pipe 303 and sprayed onto the surface of the stones conveyed on the belt conveyor 1 through the first guide pipe 301, the first branch pipe 3, and the atomizing nozzle 304. This wets the dust on the surface of the stones, reducing the amount of dust generated when the stones are loaded and unloaded into the loading and unloading vehicle. Simultaneously, the exhaust fan 405 is started by the controller to draw air into the filter box 404. Outside air enters the filter box 404 through the exhaust hood 403, the second branch pipe 4, the second guide pipe 401, and the U-shaped pipe 402. The dust generated when the stones fall into the loading and unloading vehicle is drawn into the filter box 404 and filtered through the filter frame 406. The filtered air is then discharged through the exhaust fan 405. In this way, the combined spraying and dust collection mechanisms reduce the amount of dust generated during stone loading and unloading, thereby improving the effectiveness of the dust cover body 202.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
