Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor technology, specifically relating to a tail roller seat for a belt conveyor. Background Technology

[0002] Currently, in my country's mining operations, tunneling machines are typically used in conjunction with belt conveyors. The material mined by the tunneling machine is transferred to the belt conveyor for transport. However, existing belt conveyors only have a tail pulley at the tail end. To ensure personnel safety and normal equipment operation, a protective cover is usually installed at the tail pulley. When the tail pulley needs replacement or maintenance, the protective cover must be disassembled, increasing the workload of workers and the downtime of the belt conveyor. Furthermore, because the walls of the tail pulley are relatively smooth, the belt it supports is prone to shifting. Additionally, due to localized spillage and dust in coal mine transportation systems, both sides of the belt surface accumulate coal sludge formed from a mixture of water and dust. When the belt carries this sludge, the tail pulley cannot handle it, causing it to accumulate at the tail end of the belt conveyor. This accumulated sludge adheres to the tail pulley, altering its structural dimensions and making the belt prone to shifting. The accumulated sludge also affects the rotation of the tail pulley, thus impacting the normal operation of the belt conveyor. Summary of the Invention

[0003] The purpose of this utility model is to provide a tail pulley seat for a belt conveyor, which facilitates maintenance or replacement of the tail pulley by workers. At the same time, the tail pulley with spiral grooves can handle coal sludge on the belt.

[0004] The technical solution of this utility model is as follows: a tail roller seat for a belt conveyor, comprising a base and a tail cover. The tail cover has a plurality of scraping rods inside, and an adjusting rod is provided between the scraping rods. The adjusting rod is slidably connected to the side wall of the tail cover. The end of the adjusting rod is provided with a baffle, which is located inside the tail cover. The tail cover is rotatably connected to one side of the upper surface of the base and is fastened to the upper surface of the base. A tail roller is provided in the cavity formed by the base and the tail cover. The tail roller is rotatably connected to the base. Spiral grooves are symmetrically opened on the tail roller, and a belt is attached to the tail roller.

[0005] Preferably, the base includes a set of I-shaped uprights, each with a side wall thickness of 16mm, and each upright has raised portions at both ends of its lower surface. Each upright is provided with a bearing seat, and the shafts at both ends of the tail roller are rotatably connected to the two bearing seats through bearings.

[0006] Furthermore, a tension plate is installed on one side of each of the aforementioned supports, and an ear plate is provided on one side of each tension plate.

[0007] Specifically, the tail shield consists of an outer steel plate and a set of supporting frames. Each supporting frame is composed of several square tubes with a wall thickness of 5mm. The set of supporting frames is set on a set of uprights. The set of supporting frames is connected by several supporting beams. An 8mm thick outer steel plate is wrapped around the frame structure formed by the set of supporting frames and several supporting beams. Several horizontally arranged scraping rods are connected to the outer steel plate, and the scraping rods penetrate the outer steel plate and extend to the outside of the tail shield.

[0008] Furthermore, the adjusting rod is slidably connected to the outer steel plate, and the baffle and several scraping rods at one end of the adjusting rod are slidably connected. The other end of the adjusting rod is provided with a handle.

[0009] Preferably, the tail cover is hinged to the base, and observation ports are symmetrically opened on the tail cover, with an observation cover rotatably connected to each observation port.

[0010] Furthermore, each spiral groove is equipped with reinforcing ribs.

[0011] The beneficial effects of this utility model are as follows: The tail pulley can be inspected and maintained by rotating and opening the tail cover, increasing the convenience of tail pulley maintenance, reducing the labor intensity of workers, and minimizing equipment downtime. The scraping rod removes coal sludge from the belt entering the tail cover, while the baffle limits the belt position to prevent belt deviation. The spiral grooves on the tail pulley wall increase the friction between the tail pulley and the belt, further preventing belt deviation and improving equipment stability and reliability. Simultaneously, the spiral grooves on the tail pulley treat coal sludge on the belt, preventing changes in the tail pulley's structural dimensions due to coal sludge accumulation at the tail of the conveyor, thus preventing belt deviation and ensuring normal rotation of the tail pulley, guaranteeing normal operation of the conveyor and reducing production interruptions caused by equipment failure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] When maintaining or replacing the tail pulley, the protective cover on the outside of the tail pulley needs to be removed first, which increases the workload of the workers and the downtime of the belt conveyor. At the same time, because the cylinder wall of the tail pulley is relatively smooth, the belt it supports is prone to misalignment. In addition, when the belt carries coal sludge, the tail pulley cannot handle the coal sludge on the belt, causing the coal sludge to accumulate at the tail of the belt conveyor. The coal sludge accumulated at the tail of the belt conveyor will adhere to the surface of the tail pulley, causing changes in the structural dimensions of the tail pulley and affecting the normal use of the belt conveyor. In view of this, the inventors of this application provide a tail pulley seat for belt conveyors, which can facilitate the maintenance or replacement of the tail pulley by the workers, and the tail pulley with spiral grooves can handle the coal sludge on the belt.

[0020] like Figure 1-4As shown, a tail pulley seat for a belt conveyor includes a base 1 and a tail cover 2. The tail cover 2 has several scraping rods 21 inside, and adjusting rods 22 are provided between the scraping rods 21. The adjusting rods 22 are slidably connected to the side wall of the tail cover 2. The end of the adjusting rod 22 is provided with a baffle 23, which is located inside the tail cover 2. The tail cover 2 is rotatably connected to one side of the upper surface of the base 1 and is fastened to the upper surface of the base 1. A tail pulley 3 is provided in the cavity formed by the base 1 and the tail cover 2. The tail pulley 3 is rotatably connected to the base 1. Spiral grooves 31 are symmetrically opened on the tail pulley 3, and each spiral groove 31 is provided with a reinforcing rib 32. A belt is attached to the tail pulley 3.

[0021] Based on the above embodiment, the scraper 21 scrapes away the coal slime on the belt, while the baffle 23 limits the position of the belt to prevent belt deviation. Since the tail cover 2 and the base 1 are rotatably connected, the tail pulley 3 can be maintained or replaced simply by rotating the tail cover 2, increasing the convenience of maintenance, reducing the labor intensity of workers, and minimizing equipment downtime. A spiral groove 31 is formed on the wall of the tail pulley 3 to increase the friction between the tail pulley 3 and the belt, further preventing belt deviation on the tail pulley 3 and improving the stability and reliability of the equipment. Simultaneously, the spiral groove on the wall of the tail pulley 3... 31 can treat the coal sludge on the belt conveyor, preventing it from accumulating at the tail of the conveyor and thus preventing changes in the structural dimensions of the tail pulley 3 due to excessive coal sludge adhering to it. It also ensures the normal rotation of the tail pulley 3, guaranteeing the normal operation of the conveyor and reducing production interruptions caused by equipment failure. Specifically, in this embodiment, coal sludge accumulating at the tail of the conveyor and adhering to the tail pulley 3 will cause an increase in the diameter of the tail pulley 3, making the belt prone to deviation. Furthermore, coal sludge adhering to the shaft 33 and bearing of the tail pulley 3 can easily affect the rotation of the tail pulley 3, thereby affecting the operation of the conveyor.

[0022] In this embodiment, the base 1 includes a set of I-shaped uprights 13, each upright 13 having a side wall thickness of 16mm, and each upright 13 having a raised portion 13-1 at both ends of its lower surface. Each upright 13 is provided with a bearing seat 14, and the shafts 33 at both ends of the tail roller 3 are rotatably connected to the two bearing seats 14 through bearings. Each upright 13 has a drawing plate 11 installed on one side, and each drawing plate 11 has an ear plate 12 on one side, that is, the drawing plate 11 and the ear plate 12 are symmetrically arranged on one side of the base 1.

[0023] Based on the above embodiment, the tail cover 2 and the tail roller 3 are supported by the upright 13 with a side wall thickness of 16mm, which enhances the supporting force of the base 1 and thus enhances the overall strength of the tail roller seat. By setting a set of tension plates 11 and ear plates 12 on one side of the upright 13, the overall strength and ease of operation of the tail roller seat hinge are improved. That is, it makes it easier for the staff to hinge other equipment at one end of the tail roller seat, while improving the firmness between the tail roller seat and the other equipment connected to it.

[0024] In this embodiment, the tail shield 2 is composed of an outer steel plate 24 and a set of support frames 25. Each support frame 25 is composed of several square tubes with a wall thickness of 5mm. The set of support frames 25 is set on a set of uprights 13. There are two support frames 25 and two uprights 13, that is, two support frames 25 are respectively set on two uprights 13. The set of support frames 25 are connected by support beams 28. An 8mm thick outer steel plate 24 is wrapped on the frame structure formed by the set of support frames 25 and several support beams 28. Several horizontally arranged scraping rods 21 are connected to the outer steel plate 24, and the scraping rods 21 penetrate the outer steel plate 24 and extend to the outside of the tail shield 2.

[0025] Based on the above embodiment, a support frame 25 is formed by welding square tubes with a wall thickness of 5mm and a length and width of 60mm to enhance the overall strength of the tail cover 2. By covering the frame structure formed by the support frame and the support beam with an outer steel plate 24 with a thickness of 8mm, the impact resistance of the tail cover 2 is enhanced, and the protective effect of the tail cover 2 on the tail roller 3 is improved.

[0026] In this embodiment, the adjusting rod 22 is slidably connected to the outer steel plate 24, and the baffle 23 and several scraping rods 21 at one end of the adjusting rod 22 are slidably connected. The other end of the adjusting rod 22 is provided with a handle 26.

[0027] Based on the above embodiment, by pulling the adjusting rod 22 with the handle 26, the baffle 23 is moved along the scraping rod 21, so that the operator can adjust the position of the baffle 23 inside the tail cover 2 by adjusting the adjusting rod 22, thereby adjusting the overlap position of the belt on the tail roller 3.

[0028] In this embodiment, the tail cover 2 is hinged to the base 1, and observation ports are symmetrically opened on the tail cover 2, with an observation cover 27 rotatably connected to each observation port.

[0029] Based on the above embodiment, the observation port allows staff to more easily observe whether the belt inside the tail shield 2 has shifted.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
