Description

Technical Field

[0001] This utility model relates to the field of tape conveyor technology, specifically a tape conveyor with a liftable guide trough structure. Background Technology

[0002] Belt conveyors, as core equipment for modern industrial bulk material handling, are widely used in mining, ports, power, and building materials industries. At material transfer points, guide chutes are crucial devices for preventing material spillage and dust dispersion; their sealing performance directly affects the cleanliness of the production environment, material loss, and equipment operational safety.

[0003] Currently, most material guide chutes used in the industry are fixed structures. Their bottoms are sealed to the running conveyor belt via rubber plates or other seals. However, during long-term continuous operation, the seals gradually wear down due to constant friction with the belt, leading to increased sealing gaps and consequently material spillage and dust problems. Because these fixed structures lack adjustability, once wear occurs, the machine must be stopped and the relevant parts disassembled for replacement or adjustment, which undoubtedly interrupts the production process and reduces equipment operating rates.

[0004] Existing technology 201621374608.1 discloses an adjustable wear-resistant sealing device for a conveyor belt collection trough, including an adjustable side plate that can slide up and down on the collection trough, a polyurethane blade connected to the bottom of the adjustable side plate, and a drive mechanism located on the side wall of the collection trough and connected to the adjustable side plate to drive the adjustable side plate to move the polyurethane blade up and down. The drive mechanism has a worm gear reducer fixed to the side wall of the collection trough, a drive power unit located at the power input end of the worm gear reducer, and a power transmission unit located between the power output end of the worm gear reducer and the adjustable side plate. However, during use, new limitations have been exposed, especially in harsh environments such as mines. First, its drive and execution components are usually installed as a whole on both sides of the tail chute, that is, at a high position of the equipment, making manual emergency operation inconvenient and requiring climbing to operate, and maintenance difficult. Second, the motor drive has safety restrictions in places with explosion-proof requirements, increasing the complexity and cost of the system. In addition, the screw drive mechanism has high requirements for the cleanliness of the working environment. In dusty and humid conditions, it is prone to jamming and corrosion, which can lead to a decrease in transmission efficiency or even failure, affecting the reliability of the adjustment function. Utility Model Content

[0005] The present invention aims to solve the above problems and thus provide a lifting guide trough structure for conveyor belt machines that avoids working at heights.

[0006] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0007] A lifting guide trough structure for a conveyor belt machine includes fixed supports on both sides of the conveyor belt machine frame. An adjusting plate is connected to the fixed supports via a sliding guide structure. The adjusting plate can be raised and lowered along the sliding guide structure. A wear-resistant sealing plate is provided at the bottom of the adjusting plate, and an elastic sealing edge is provided at the top of the adjusting plate extending horizontally inward. A manual self-locking winch is installed at the lower part of the conveyor belt machine frame, and a first fixed pulley is provided at the top of the conveyor belt machine frame. A second fixed pulley is provided above the adjusting plate. The wire rope on the manual self-locking winch passes around the first and second fixed pulleys in sequence and is fixed to the top of the conveyor belt machine frame.

[0008] Compared with the prior art, the present utility model adopting the above technical solution has the following outstanding features:

[0009] By installing a manual self-locking winch at the bottom of the conveyor belt frame and using a traction system consisting of fixed pulleys and wire ropes to drive the lifting and lowering of the high-position adjustment plate, operators can perform adjustments from the ground without having to climb, reducing operational difficulty and safety risks. The purely mechanical transmission method is highly adaptable to dusty and humid environments, avoiding the limitations of electric systems in explosion-proof environments and the problem of screw assembly jamming, thus improving reliability. Simultaneously, this structure allows for real-time adjustment of the sealing gap during conveyor belt operation, effectively compensating for wear and helping to maintain production continuity.

[0010] As a preferred embodiment, a further technical solution of this utility model is:

[0011] Furthermore, the fixed support includes multiple support rods spaced apart along the running direction of the conveyor belt. The support rods include vertical poles and horizontal poles that are perpendicular to each other. The bottom end of the vertical pole is fixed to the frame of the conveyor belt, one end of the horizontal pole is fixed to the top end of the vertical pole, and the other end of the horizontal pole points into the conveyor belt. This provides a stable installation foundation for the entire lifting guide chute, distributes the load, and its modular design allows for flexible arrangement and installation according to the size of the conveyor belt and the length of the guide chute on site, enhancing the overall rigidity and adaptability of the structure.

[0012] Furthermore, the crossbar is groove-shaped, and the inner ends of the two crossbars are symmetrically equipped with sealing plates. The sliding guide structure includes a longitudinal guide groove set on the adjusting plate. A guide bolt passes through the guide groove and the sealing plate. A guide nut connected to the end of the guide bolt is set inside the crossbar. A sliding gap is formed between the rod body of the guide bolt and the groove wall of the guide groove. The cooperation between the guide bolt and the guide groove ensures the linearity and stability of the lifting and lowering movement of the adjusting plate.

[0013] Furthermore, the wear-resistant sealing plate is made of rubber. Rubber material has good elasticity and a certain degree of wear resistance, which can effectively adhere to the surface of the tape to form a seal. At the same time, it is relatively economical and suitable for working conditions that require frequent replacement or are cost-sensitive.

[0014] Furthermore, the wear-resistant sealing plate is installed at the bottom of the adjusting plate via a detachable connection. After the sealing plate wears out, it can be easily replaced individually without disassembling the entire feed chute or adjusting plate, which greatly simplifies the maintenance process, shortens downtime, and reduces maintenance costs.

[0015] Furthermore, the elastic sealing edge is made of rubber. The rubber sealing strip is soft and can adapt well to the irregular gap between the rubber and the side wall of the upstream chute, forming an effective secondary seal. This further prevents fine materials and dust from escaping from the top and enhances the overall sealing effect.

[0016] Furthermore, the manual self-locking winch, the first fixed pulley, the second fixed pulley, and the wire rope constitute a drive unit. At least two drive units are provided on one side and are symmetrically arranged on both sides of the conveyor belt frame. The multiple drive units on one side mean that the different positions of the adjusting plate along the length direction can be controlled independently or in a coordinated manner. This not only makes the overall lifting and lowering more stable, but more importantly, it makes it possible to adjust the tilt of the adjusting plate. For example, when the conveyor belt deviates or has uneven wear, the height of one end can be adjusted separately to compensate, which improves the precision and applicability of the adjustment.

[0021] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0022] This structure is mainly installed below the tail or transfer point of the belt conveyor. Its core function is to allow the height of the guide chute sealing plate to be adjusted via ground operation during normal operation of the belt conveyor, in order to compensate for wear and prevent material spillage.

[0023] A lifting guide chute structure for a conveyor belt machine includes fixed supports 2 on both sides of the conveyor belt machine frame 1. The fixed supports 2 are symmetrically installed on both sides of the conveyor belt frame 1 (typically longitudinal beams on both sides of the conveyor belt) via clamps, welding, or bolts. Adjusting plates 3, made of steel plates, are connected to the fixed supports 2 via a sliding guide structure. The length of the adjusting plates 3 matches the required enclosed guiding area. The adjusting plates 3 can be raised and lowered along the sliding guide structure. A wear-resistant sealing plate is provided at the bottom of the adjusting plates 3. 4. An elastic sealing edge 5 extends horizontally inward from the top of the adjusting plate 3. A manual self-locking winch 6 is installed at the lower part of the conveyor belt frame 1. The manual self-locking winch 6 is about 1 meter above the ground for easy operation by the operator standing. A first fixed pulley 7 is installed at the top of the conveyor belt frame 1, and a second fixed pulley 8 is installed on the upper part of the adjusting plate 3. The second fixed pulley 8 is located on the upper part of the two opposing sides of the adjusting plates 3. The steel wire rope on the manual self-locking winch 6 passes through the first fixed pulley 7 and the second fixed pulley 8 in sequence and is fixed to the top of the conveyor belt frame 1. A fixing lug 9 connected to the steel wire rope is provided at the top of the conveyor belt frame 1 and directly above the second fixed pulley 8.

[0024] Furthermore, the fixed bracket 2 includes multiple support rods spaced apart along the running direction of the conveyor belt. The support rods include vertical poles and horizontal poles that are perpendicular to each other. The bottom end of the vertical pole is detachably fixed to the conveyor belt frame 1 by bolts. One end of the horizontal pole is fixed to the top end of the vertical pole, and the other end of the horizontal pole is welded or bolted to the top end of the vertical pole. The other end of the horizontal pole points towards the inside of the conveyor belt, providing a stable installation foundation for the entire lifting guide chute and distributing the load. Its modular design facilitates flexible arrangement and installation according to the size of the conveyor belt and the length of the guide chute on site, enhancing the overall rigidity and adaptability of the structure.

[0025] Furthermore, the crossbars are groove-shaped, and symmetrical sealing plates are arranged at the inner ends of the two crossbars. The bottom of the sealing plates on both sides forms an angle between 60-90° and the horizontal plane. Because the longitudinal section of the discharge chute is not exactly a rectangle with equal width, it may also be bucket-shaped. When the longitudinal section of the discharge chute is rectangular, the sealing plates are set perpendicular to the horizontal plane, causing the rubber plate to also be in a vertical state. When the discharge chute is bucket-shaped, the two sealing plates have an inward octagonal inclined structure. The inclination angle of the sealing plates (along with the adjusting plate 3 and the wear-resistant sealing plate 4 connected to them) is consistent with the inclination angle of the side wall of the bucket-shaped chute, ensuring that the gap between the adjusting plate and the side wall of the bucket-shaped chute is of consistent width in the vertical direction. The sliding guide structure includes the longitudinal section set on the adjusting plate 3. The guide groove 10 is oriented in the direction of the guide, and the guide bolt 12 passes through the guide groove 10 and the sealing plate. The guide nut 11 connected to the end of the guide bolt 12 is provided in the crossbar. A sliding gap is formed between the rod body of the guide bolt 12 and the groove wall of the guide groove 10. The cooperation between the guide bolt 12 and the guide groove 10 ensures the linearity and stability of the lifting and lowering movement of the adjusting plate 3. The guide nut 11 can be tightened appropriately after the adjusting plate 3 is accurately positioned. Its purpose is not to rigidly clamp the adjusting plate 3 and the crossbar, but to provide a moderate anti-loosening force to prevent the adjusting plate 3 from producing unexpected swaying or shaking due to the existence of the guide gap during long-term operation and vibration of the belt conveyor. At the same time, it retains its sliding property when it needs to be adjusted again.

[0026] Furthermore, the wear-resistant sealing plate 4 is a rubber plate. The rubber plate is made of flame-retardant material. The rubber material has good elasticity and a certain degree of wear resistance, which can effectively adhere to the surface of the tape to form a seal. At the same time, its cost is relatively economical and it is suitable for working conditions that require frequent replacement or are cost-sensitive.

[0027] Furthermore, the wear-resistant sealing plate 4 is installed at the bottom of the adjusting plate 3 via a detachable connection. After the sealing plate wears out, it can be easily replaced without disassembling the entire feed chute or adjusting plate 3, which greatly simplifies the maintenance process, shortens downtime, and reduces maintenance costs.

[0028] Furthermore, the elastic edge seal 5 is a rubber seal. The rubber seal is soft and made of flame-retardant material, which can adapt well to the irregular gap between the rubber seal and the side wall of the upstream chute, forming an effective secondary seal, further preventing fine materials and dust from escaping from the top, and enhancing the overall sealing effect.

[0029] Furthermore, the manual self-locking winch 6, the first fixed pulley 7, the second fixed pulley 8, and the wire rope constitute a set of drive units. At least two sets of these drive units are provided on one side and are symmetrically arranged on both sides of the conveyor belt frame 1. The multiple sets of drive units on one side mean that the different positions of the adjusting plate 3 along the length direction can be controlled independently or in a coordinated manner. This not only makes the overall lifting and lowering more stable, but more importantly, it provides the possibility of tilting the adjusting plate 3. For example, when the conveyor belt deviates or has uneven wear, the height of one end can be adjusted separately to compensate, which improves the precision and applicability of the adjustment.

[0030] The outstanding advantages of this conveyor belt's liftable guide chute structure lie in its low-position operation and improved environmental adaptability. The specific working process is as follows: The operator does not need to climb; they simply stand beside the conveyor belt and crank the manual self-locking winch 6 handwheel, which is installed at the lower part of the conveyor belt frame 1 (approximately 1 meter above the ground). By winding the steel wire rope, the rope passes sequentially around the first fixed pulley 7 at the top of the conveyor belt frame 1 and the second fixed pulley 8 on the upper part of the adjusting plate 3, finally securing it to the top of the frame. This transmission process constitutes a labor-saving moving pulley system, which can smoothly lift the adjusting plate 3, connected to the fixed bracket 2 via a sliding guide structure, and its bottom wear-resistant sealing plate 4 upwards. This allows for real-time and convenient compensation for increased sealing gaps due to wear, even while the conveyor belt is continuously running. This purely mechanical drive effectively avoids the safety risks associated with operating from heights and has strong tolerance to dusty and humid mining environments. It overcomes the limitations of electric systems in explosion-proof environments and the tendency for screw drives to jam. Furthermore, since the drive unit has at least two sets of symmetrically arranged units on each side, operators can selectively operate different rope coilers on one side or the same side individually. This not only achieves smooth overall lifting and lowering of the adjusting plate 3, but also enables it to tilt along its length, precisely adapting to complex working conditions such as belt misalignment or uneven local wear. Simultaneously, the wear-resistant sealing plate 4 is detachably installed at the bottom of the adjusting plate 3, allowing for easy replacement when worn, simplifying maintenance. The elastic sealing edge 5 extending horizontally inward from the top of the adjusting plate 3 forms an effective seal with the upstream chute sidewall, preventing dust escape. The modular fixing bracket 2, composed of mutually perpendicular uprights and crossbars, provides a stable and adaptable installation foundation for the entire structure.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
