Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, specifically to a guide trough. Background Technology

[0002] Traditional belt conveyor chutes often suffer from poor sealing between the belt supported by idlers and the chutes' sealing strips, leading to dust generation and material leakage during transport. Current improved chutes utilize idlers and double sealing strips; however, the idlers cannot provide continuous support, causing localized belt sagging and resulting in inadequate sealing. Furthermore, if the double sealing strips are in close contact with the belt, they are prone to friction damage. When two belt conveyors cross vertically, material falling into the chutes rarely lands precisely on the belt's centerline, easily causing belt deviation. Utility Model Content

[0003] This utility model was made to solve the above-mentioned technical problems. One of its objectives is to provide a guide groove that can prevent the tape from running off-track.

[0004] Another objective of this invention is to provide a material guide trough with better sealing effect, so as to avoid dust or material leakage during material transportation.

[0005] According to one embodiment of the present invention, a material guide trough is provided, comprising: a frame with a feed inlet at the top; a conveyor belt disposed in the frame; a plurality of first rollers disposed on the frame to provide horizontal support for the conveyor belt; a plurality of second rollers disposed at an incline on the frame to provide support for both sides of the conveyor belt toward the center; and a discharge chute disposed at the feed inlet, with a discharge outlet at the lower end that converges toward the center and is opposite to the conveyor belt.

[0006] In one embodiment, the material chute is bolted to the frame.

[0007] As one implementation, the inner side of the discharge chute is provided with a liner.

[0008] As one embodiment, the guide trough further includes: two sets of first seals disposed in the frame, with their lower ends respectively abutting against two sides of the upper surface of the tape; wherein the tape, the first seals and the top surface of the frame form a sealed space.

[0009] As one embodiment, a support plate is provided in the material drop section of the guide trough to support both sides of the tape along the length direction.

[0010] As one implementation, the front and rear ends of the tray are provided with arc-shaped guide surfaces.

[0011] In one embodiment, in the non-discharge section of the guide chute, a tray is provided every 2 to 6 of the second idlers.

[0012] In one embodiment, the first sealing element is a flexible strip.

[0013] As one embodiment, the guide trough further includes a second sealing element disposed on both sides of the frame.

[0014] In one embodiment, the second seal is a transparent plate.

[0015] Based on the above description and practical application, it can be seen that the material guide chute of this utility model is equipped with a discharge chute at the feed inlet of the frame. The lower end of the discharge chute forms a discharge outlet that converges towards the center and is opposite to the conveyor belt. When two belt conveyors are perpendicularly feeding material, the material falls into the material guide chute. Even if its falling direction is biased towards the sides of the feed inlet, it can be guided by the discharge chute and fall in the middle of the conveyor belt, preventing the conveyor belt from running off-center. This ensures that the material guide chute can operate stably for a long time.

[0016] In addition, the guide chute is equipped with first sealing elements on both sides of the frame and the conveyor belt, forming a closed space between the conveyor belt, the first sealing elements and the top surface of the frame for material movement, which improves the sealing effect during material conveying and can significantly avoid dust and material leakage.

[0017] Furthermore, in the material drop section of the guide chute, support plates are installed to provide longitudinal support to both sides of the conveyor belt. This prevents downward displacement of the conveyor belt between the second idlers, thereby avoiding gaps between the conveyor belt and the first seal and further improving the airtightness of the guide chute during use.

[0018] In addition, transparent second seals are installed on both sides of the frame to further improve the sealing effect and ensure that the material guide chute does not generate dust when conveying materials. Attached Figure Description

[0024] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0025] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] According to one embodiment of this utility model, a material guide trough is provided. Please refer to [reference needed]. Figure 1 and Figure 2 The material guide chute includes a frame 1, a conveyor belt 2, several first rollers 3, several second rollers 4, and a discharge chute 5.

[0027] The frame 1 is the main support structure of the material guide chute. It has multiple support rods at the bottom and sides, and a top plate at the top. A feed inlet is formed on the top plate. The material enters the frame 1 through the feed inlet and is then conveyed by other structures within the frame 1.

[0028] The conveyor belt 2 is arranged inside the frame 1 along its length. Several first idlers 3 are distributed below the conveyor belt 2 along its length. The two ends of the first idlers 3 are rotatably connected to the frame 1, and the upper side abuts against the conveyor belt 2 to form a horizontal support for the first conveyor belt 2. By rotating the first idlers 3, the conveyor belt 2 is driven to move forward to convey materials.

[0029] Several second idlers 4 are distributed along the length of the conveyor belt 2 on the lower side of both sides. The second idlers 4 are inclined and rotatably connected to the frame 1 at both ends. The upper side of the second idler 4 abuts against the lower side of the conveyor belt 2, forming a support for the two sides of the conveyor belt 2 towards the middle, so that the conveyor belt 2 forms a near-arc structure with the two sides raised upward and the middle concave, which can prevent the material from falling from the sides.

[0030] The material discharge chute 5 is located at the feed inlet of the frame 1, and its lower end forms a discharge outlet that converges towards the center and faces the conveyor belt 2. When the two belt conveyors are perpendicularly discharging material, the material falls into this guide chute. Even if its falling direction is biased towards the sides of the feed inlet, it can be guided by the material discharge chute 5 and land in the middle of the conveyor belt 2, preventing the conveyor belt 2 from running off-center and ensuring the long-term stable operation of the guide chute. A certain distance is reserved between the lower end of the material discharge chute 5 and the conveyor belt 2 to facilitate material passage and ensure that material does not accumulate in the material discharge chute 5.

[0031] As one implementation method, the material discharge chute 5 is bolted to the frame 1 for easy assembly and disassembly.

[0032] As one implementation, a liner 9 is provided on the inner side of the material discharge chute 5. The liner 9 can be made of wear-resistant structural components, which can extend its service life. Alternatively, the liner 9 can be installed on the inner wall of the material discharge chute 5 using countersunk bolts. After the liner 9 is damaged from long-term use, it can be removed and replaced with a new liner 9 using bolts, without having to replace the entire material discharge chute 5, which can reduce maintenance costs to some extent. In addition, the countersunk bolts are located inside the surface of the liner 9, so they will not affect the material falling into the frame 1.

[0033] In one embodiment, the feed channel also includes two sets of first seals 6. For example... Figure 1 As shown, the first sealing element 6 is disposed in the frame 1, with its upper end fixedly connected to the frame 1 and its lower end abutting against two sides of the upper surface of the tape 2. Therefore, a sealed space is formed between the tape 2, the two sets of first sealing elements 6, and the top surface of the frame 1. This is equivalent to the entire material guide chute, except for the inlet and outlet, being a sealed space for material conveying. This improves the sealing effect during material conveying and significantly avoids dust and material leakage. In a specific embodiment, the first sealing element 6 is a flexible strip. During the material conveying process of the tape 2, the lower end of this type of first sealing element 6 can stably abut against the tape 2, maintaining a good sealing effect.

[0034] As one implementation, a support plate 8 is provided in the material drop section of the feed chute, providing longitudinal support to both sides of the conveyor belt 2. The material drop section refers to the section with the feed inlet. In this section, material falls onto the conveyor belt 2 through the feed inlet, impacting the belt and causing downward displacement. In the area between the two idlers, after the conveyor belt 2 deflects downward, a gap forms between its upper surface and the first seal 6, allowing dust from inside the frame 1 to easily overflow from this area. By providing the support plate 8, a larger range of support is provided along the length of the conveyor belt 2, preventing this portion of the belt 2 from moving downward, thus avoiding the risk of contact with the first seal 6. This ensures that during operation, the material remains in a relatively sealed space within the feed chute, preventing dust and material leakage.

[0035] Furthermore, in this embodiment, the front and rear ends of the tray 8 are provided with arc-shaped guide surfaces. When the tape 2 comes into contact with the tray 8, the tape 2 will not experience significant wear due to the guide surfaces. Even further, the left and right sides of the tray 8 are also provided with arc-shaped guide surfaces, which can also reduce friction with the tape 2 and improve the service life of both. In a specific embodiment, the tray 8 is a smooth polyurethane board, which can further reduce friction with the tape 2 and improve the service life of both.

[0036] As one implementation, in the non-dropping section of the guide chute, a pallet 8 is provided every 2 to 6 second idlers 4, which can improve the tightness of the connection between the tape 2 and the first seal 6 in the non-dropping section of the guide chute, avoid gaps between the two, and ensure that dust and material leakage are avoided throughout the entire conveying path.

[0037] As one implementation, the guide trough also includes a second sealing element 7, which is disposed on both sides of the frame 1. The second sealing element 7 can enclose the various idler rollers, conveyor belts 2, and other structural components inside the frame 1, further improving the effect of the guide trough in suppressing dust and material leakage. Furthermore, in this embodiment, the second sealing element 7 is a transparent plate, which is bolted to the frame 1. This allows users to easily observe the operation of the internal idler rollers and support plates 8, effectively preventing dust overflow and facilitating installation and disassembly. It should be noted that, in order to demonstrate the relevant structures inside the guide trough, [the following text is incomplete and requires further context]. Figure 2 The second seal 7 is omitted.

[0038] In one embodiment, a connecting plate is provided on the frame 1, and an elongated hole is provided on the connecting plate. The second seal 7 is bolted into the elongated hole to facilitate adjustment of the installation position of the second seal 7.

[0039] When two belt conveyors are perpendicularly discharging material, the ordinary belt conveyor's guide chute lacks a material-gathering function. Material may impact the edge of the belt 2, causing additional horizontal thrust and deviation of the belt 2. Alternatively, material may impact the side plate of the guide chute, leading to wear and leakage if not replaced promptly. This invention combines the guide chute with a discharge chute 5. The discharge chute 5 is installed inside the guide chute, and liners 9 are installed on the side walls of the discharge chute 5, extending its service life and effectively preventing material deviation.

[0040] In ordinary belt conveyors, gaps exist between adjacent idlers in the guide trough, preventing continuous support of the outer edge of the belt 2. This causes the belt 2 to sag, creating gaps between it and the rubber strip inside the guide trough. Material or dust can easily spill out from these gaps, affecting the working environment. Even using double sealing strips cannot eliminate these gaps. If the guide trough rubber strip is pressed tightly against the belt 2, significant friction is generated, leading to internal power loss in the belt conveyor. Furthermore, the guide trough sealing strip or double sealing strip is prone to wear, resulting in a short service life. Excessive compression can also cause the rubber strip and belt 2 to rub together and heat up, melting the rubber surface and causing adhesion during shutdown, affecting startup. In this invention, the lower end of the first sealing element 6 rests against the rubber pad, resulting in near-line contact. The small contact area minimizes wear and reduces service life. Moreover, due to the support of the support plate 8, the first sealing element 6 can better adhere to the rubber strip, preventing material and dust spillage.

[0041] Ordinary belt conveyor chutes lack external seals, allowing dust to easily spill out between the chute's rubber strip and the belt 2, affecting the working environment. Some chutes have external seals, but these hinder maintenance and observation of the internal equipment's operation. This invention addresses this issue by using a first seal 6 between the first sealing element 6 and the belt 2, and a second seal 7 on the outside of the chute frame 1. The second seal 7 is made of a transparent plate, allowing real-time observation of the internal equipment's operation and effectively preventing dust spillage. When maintenance is required, the second seal 7 can be removed by unscrewing the connecting bolts.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
