[0028] Currently, most belt conveyors adopt the TD75 and DTⅡ design selection standards. In existing technologies, the dustproof seal in the middle of the belt conveyor mainly relies on the guide trough. The single-layer rubber baffle of the guide trough has poor sealing with the belt and is prone to wear, which affects the dust removal effect in the middle of the belt conveyor. Ultimately, this causes dust generation and poor dust removal effect when the belt conveyor is conveying dry powder materials.

[0029] In view of this, this application proposes a dustproof material guide trough for a belt conveyor.

[0030] In the embodiments of this application, reference is made to Figures 1 to 3The aforementioned dustproof guide chute for a belt conveyor includes a conveyor belt 1 mounted on a support 2. A guide chute 3 covers the outer side of the conveyor belt 1. The guide chute 3 includes a cover 310 with a gap between it and the conveyor belt 1. The cover 310 covers the conveyor belt 1. Guide plates 320 are installed on both sides of the cover 310 near the conveyor belt 1. Dustproof plates 330 are installed on the outer side of the guide plates 320. Both the guide plates 320 and the dustproof plates 330 are mounted on the cover 310 via a clamping structure 340. Both the guide plates 320 and the dustproof plates 330 are in soft contact with the conveyor belt 1, forming a dustproof barrier between the guide plates 320 and the corresponding dustproof plates 330. Dust-proof space: When the conveyor belt 1 is running, the material is conveyed on the conveyor belt 1. The cover 310 covers the conveyor belt 1. The guide plate 320 and the dustproof plate 330 are in soft contact with the conveyor belt 1. The guide plate 320 guides the material and prevents dust, blocking most of the dust. A small amount of dust will pass through the guide plate 320 and be blocked by the dustproof plate 330. This part of the dust will be confined within the dustproof space. The cover 310 covers the space above the conveyor belt 1, the guide plate 320 guides the material to prevent the material from spilling, and the dustproof plate 330 prevents the dust from escaping. The soft contact between the two and the conveyor belt 1 ensures a sealing effect. The dustproof space formed is used to collect dust.

[0031] In this embodiment, the cover 310 includes a top plate 311 and side plates 312 located on both sides of the top plate 311. The two side plates 312 are symmetrically distributed on both sides of the top plate 311, and the top plate 311 and the two side plates 312 are connected by screws. The top plate 311 and the side plates 312 are connected by screws to form the cover 310, which together cover the conveyor belt 1. The split design and screw connection facilitate installation and disassembly, making it convenient to maintain and repair the inside of the cover 310. This improves the ease of installation and maintenance of the cover 310 and reduces maintenance costs.

[0032] In this embodiment, the guide plate 320 includes a connecting part 321 and a guiding part 322. Both side plates 312 are inclined towards the middle. The guide plate 320 is installed on the corresponding side plate 312. The connecting part 321 is parallel to and fits against the corresponding side plate 312. The guiding part 322 fits against the contact surface of the conveyor belt 1. The inclined arrangement of the side plates 312 causes the material to concentrate towards the middle of the conveyor belt 1. The shape and installation method of the guide plate 320 enable it to better fit the conveyor belt 1 and the side plate 312, effectively guiding the material. This improves the guiding effect of the material and reduces the scattering of the material during the conveying process.

[0033] In this embodiment, the guide plate 320 is a structure made of elastic material, specifically rubber. When the guide plate 320 made of elastic material comes into contact with the conveyor belt 1, it can undergo elastic deformation according to factors such as the running condition of the conveyor belt 1 and the weight of the material. The characteristics of the elastic material enable the guide plate 320 to better adapt to different states of the conveyor belt 1, maintain good contact with the conveyor belt 1, enhance the fit between the guide plate 320 and the conveyor belt 1, and improve the guiding and dustproof effects.

[0034] In this embodiment, several support members 4 are respectively provided on both sides of the cover 310. The support members 4 are equidistantly distributed. One end of the support member 4 is connected to the cover 310, and the other end of the support member 4 is connected to the bracket 2. The support members 4 provide support for the cover 310. Through the equidistantly distributed support members 4, the weight of the cover 310 is evenly transferred to the bracket 2, ensuring the stability of the cover 310. This improves the structural stability of the cover 310, enabling it to better bear the weight of materials and itself, and extending its service life.

[0035] In this embodiment, the dustproof plate 330 is a structure made of flexible material, specifically soft rubber or silicone. The flexible material dustproof plate 330 can better adapt to different states of the conveyor belt 1 under the action of gravity. The dustproof plate 330 includes an installation part 331 and a dustproof part 332. The installation part 331 is attached to the guide plate 320. The end of the dustproof part 332 away from the installation part 331 is fixedly connected to a counterweight strip 333. The counterweight strip 333 is used to keep the dustproof part 332 vertical and has soft contact with the conveyor belt 1. The counterweight strip 333 keeps the dustproof part 332 in a vertical state, forming a dustproof space between the dustproof part 332 and the inclined guide plate 320. This avoids the guide plate 320 affecting the dustproof effect of the dustproof plate 330. At the same time, the dustproof space collects dust, which is convenient for centralized cleaning later. This improves the dustproof performance of the dustproof plate 330, effectively blocks dust from being blown out, and the flexible material is less likely to damage the conveyor belt 1.

[0036] In this embodiment, the clamping structure 340 includes an L-shaped pressure block 341. One end of the short side of the pressure block 341 contacts the side of the cover 310, or it can be hinged. The long side of the pressure block 341 extends to the outside of the guide plate 320 and the dustproof plate 330. A V-shaped clamping block 342 is provided between the long side of the pressure block 341 and the dustproof plate 330. Both ends of the clamping block 342 press on the dustproof plate 330, and the long side of the pressure block 341 presses on the clamping block 342. A bolt assembly 343 is provided through the middle of the pressure block 341, and the other end of the bolt assembly 343 is connected to the cover 310. The pressure block 341 is connected to the cover 310 through the bolt assembly 343. The guide plate 320 and dustproof plate 330 are fixed to the cover 310 by clamping block 342. The V-shaped clamping block 342 has its two ends pressing on the dustproof plate 330, and the long side of the pressing block 341 pressing on the clamping block 342. Under pressure, the clamping block 342 can evenly press the two ends on the guide plate 320 and dustproof plate 330. Through the tightening force of bolt assembly 343, the guide plate 320 and dustproof plate 330 are firmly installed on the cover 310, ensuring their stable position. This method facilitates the installation and fixing of the guide plate 320 and dustproof plate 330, with good fixing effect and easy maintenance and replacement.

[0037] In this embodiment, the head and tail of the conveyor are respectively covered with dustproof housings 5, and the two housings 5 ​​are respectively connected to the two ends of the cover 310. The housings 5 ​​at the head and tail of the conveyor are connected to the cover 310 to form a closed space together. This further improves the dustproof effect, reduces the leakage of dust at the head and tail of the conveyor, and improves the working environment.

[0038] In this embodiment, a dustproof partition curtain is provided between the cover 310 and the two shells 5. The partition curtain is made of flexible material. The partition curtain plays a buffering and sealing role between the cover 310 and the shell 5, reducing dust leakage at the connection. The flexible material of the partition curtain can adapt to the relative movement between the cover 310 and the shell 5, while blocking dust leakage through the connection, enhancing the sealing performance at the connection between the cover 310 and the shell 5, reducing dust leakage, and improving the overall dustproof effect.

[0039] In this embodiment, a dust suction pipe 6 is also connected to the cover 310, and the other end of the dust suction pipe 6 is connected to a dust collection device. The negative pressure generated by the dust collection device is used to suck out the dust inside the cover 310 through the dust suction pipe 6, thereby reducing the dust concentration inside the cover 310. This further improves the working environment, reduces the harm of dust to equipment and personnel, and helps to improve the operating efficiency and service life of the equipment.

[0040] This application's technical solution involves setting a guide chute on the outer side of the conveyor belt. The guide chute includes a cover body that covers the conveyor belt. Guide plates are installed on both sides of the cover body near the conveyor belt, and dustproof plates are installed on the outer side of the guide plates. Both the guide plates and dustproof plates are mounted on the cover body via a clamping structure. Both the guide plates and dustproof plates are in soft contact with the conveyor belt, forming a dustproof space between the guide plates and their corresponding dustproof plates. When the conveyor belt is running, the material is conveyed on the conveyor belt. The cover body covers the conveyor belt, and the guide plates and dustproof plates are in soft contact with the conveyor belt. The guide plates play a role in... The guide plate and dustproof plate serve to guide and prevent dust from escaping. The guide plate will pass through the guide plate and be blocked by the dustproof plate, thus confining the dust within the dustproof space. The cover encloses the space above the conveyor belt, the guide plate guides the material to prevent spillage, and the dustproof plate prevents dust from escaping. Both the guide plate and the conveyor belt make soft contact to ensure a sealing effect. The resulting dustproof space is used to collect dust.
