Description

Technical Field

[0001] This utility model relates to the technical field of mining conveying equipment, specifically to a scraper structure for a mining conveyor. Background Technology

[0002] The working principle of a scraper conveyor is to use an open chute as a load-bearing component for coal, gangue, or other materials, and to fix scrapers onto a chain (forming a scraper chain) as a traction component. When the head drive unit starts, it drives the sprocket on the head shaft to rotate, causing the scraper chain to circulate and move the material along the chute until it is unloaded at the head of the conveyor. The scraper chain runs in a stepless closed loop around the sprocket, completing the material conveying process.

[0003] Publication (Announcement) No.: CN215796365U discloses a self-lubricating scraper for mining. Lubricating blocks are fixedly installed on the axe heads at both ends of the scraper body. The lubricating blocks are located on the surface of the scraper body axe heads that contacts the bottom plate of the scraper conveyor or scraper transfer machine, which is the upper surface of the scraper body axe heads. An installation groove is formed on the upper surface of the scraper body axe heads for installing the lubricating blocks. The surface of the lubricating blocks that contacts the bottom plate of the scraper conveyor or scraper transfer machine is higher than the upper surface of the scraper body axe heads.

[0004] The existing technical problems in mining conveying equipment are as follows: the replacement of worn conveyor scrapers and the disassembly of chains are difficult and inconvenient to replace; the lack of protective measures for worn conveyor scrapers increases the number of times the conveyor scrapers need to be replaced and maintained, resulting in a decrease in the efficiency of mining conveying equipment.

[0005] Therefore, a scraper structure for a mining conveyor is needed. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a scraper structure for a mining conveyor, aiming to solve the technical problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a scraper structure for a mining conveyor, comprising a conveyor frame and a scraper conveying channel. One side of the conveyor frame is configured as the scraper conveying channel, and several conveyor scraper assemblies are evenly distributed within the channel. The internal clamping of each scraper assembly is configured as a double chain, which drives the scraper assembly to slide within the scraper conveying channel to transport coal between two adjacent scraper assemblies. Each scraper assembly includes a main scraper, a chain clamping plate, and a wear-resistant plate. The main scraper is slidably disposed within the scraper conveying channel, and a slot is formed at the bottom of the main scraper. The upper part of the placement slot is evenly provided with screw holes one. A chain clamping plate is installed inside the placement slot. The upper part of the chain clamping plate is symmetrically provided with limiting blocks. A chain is sleeved around the limiting block. The two sides of the limiting block are provided with screw hole sleeve one. The screw hole sleeve one and the screw hole one are fixedly installed with countersunk bolts to fix the chain clamping plate inside the placement slot. The double chain clamping is installed between the placement slot and the chain clamping plate. A wear-resistant plate is installed on the surface of the main scraper facing the sliding direction. One side of the wear-resistant plate is provided with screw hole two. A screw hole three is opened on the main scraper, which is coaxial with screw hole two. Screw hole two and screw hole three are fixedly installed with countersunk bolts.

[0008] Preferably, the main scraper has an insertion groove in the middle of the side facing its sliding direction. A first-type card holder is evenly distributed axially inside the insertion groove. The main scraper surfaces on both sides of the insertion groove are symmetrically configured with arc-shaped card blocks. An arc-shaped insert plate is provided on the end face of the arc-shaped card block away from the main scraper. An arc-shaped slot is symmetrically opened on the side of the wear-resistant plate facing the main scraper. The arc-shaped slot extends towards the main scraper to form an arc-shaped card groove. A columnar protrusion is provided in the middle of the side of the wear-resistant plate facing the main scraper. A second-type card plate is axially positioned on the columnar protrusion and spaced apart. When the wear-resistant plate is installed with the main scraper, the columnar protrusion is inserted into the insertion groove, and the second-type card plate passes between two adjacent first-type card holders. By rotating the wear-resistant plate, the second-type card plate is rotated and locked inside the first-type card holder. The arc-shaped slot and the arc-shaped insert plate are inserted, and the arc-shaped card groove and the arc-shaped card block are inserted, thus forming a position for the wear-resistant plate to be installed on the main scraper.

[0009] Preferably, the two arc-shaped blocks and the two arc-shaped inserts are arranged in a horizontal rotational symmetry, and the two arc-shaped slots and the two arc-shaped card slots are arranged in a horizontal rotational symmetry.

[0010] Preferably, a long through hole is opened in the middle of the wear-resistant plate.

[0011] Preferably, the insertion slot, arc-shaped card block, arc-shaped insertion plate, arc-shaped slot, and arc-shaped card groove are arranged with a coaxial structure.

[0012] Preferably, the wear-resistant plate includes a high-manganese steel layer, a chromium cast iron layer, and an alumina ceramic layer arranged sequentially, with the high-manganese steel layer being attached to the main scraper.

[0013] In summary, this utility model provides a scraper structure for a mining conveyor. This utility model patent uses a screw hole sleeve and a screw hole to be fixedly installed with countersunk bolts, thereby achieving the fixed installation between the chain clamping plate and the main scraper. This completes the clamping installation of the double chain between the chain clamping plate and the main scraper, enabling the conveyor scraper assembly to be pulled by the double chain to transport coal.

[0014] Screw holes two and three are fixedly installed by countersunk bolts to achieve the fixed installation of the main scraper and the wear-resistant plate, thereby increasing the wear resistance of the main scraper. When the wear-resistant plate wears out, only the wear-resistant plate needs to be replaced, which improves the utilization rate of the main scraper and the timeliness of wear replacement.

[0015] Rotate the wear-resistant plate counterclockwise to make the second clamping plate rotate and engage inside the first clamping seat. Simultaneously, the arc-shaped slot engages with the arc-shaped insert plate, and the arc-shaped groove engages with the arc-shaped clamping block to form a wear-resistant plate clamping position on the main scraper. Then, use countersunk bolts to fix the screw holes two and three to achieve the fixed installation of the wear-resistant plate on the main scraper. This structure also enables rapid replacement of the wear-resistant plate due to wear, which helps to improve the efficiency of the mining conveyor. Attached Figure Description

[0025] This utility model relates to a scraper structure for a mining conveyor, comprising a conveyor frame 1 and a scraper conveying channel 2. The scraper conveying channel 2 is located on one side of the conveyor frame 1. Several conveyor scraper assemblies 3 are evenly distributed within the scraper conveying channel 2. The internal clamping of each conveyor scraper assembly 3 is configured with a double chain 4, which drives the scraper assembly 3 to slide within the scraper conveying channel 2, thereby transporting coal between two adjacent conveyor scraper assemblies 3. Each conveyor scraper assembly 3 includes a main scraper 5, a chain clamping plate 6, and a wear-resistant plate 7. The main scraper 5 is slidably disposed within the scraper conveying channel 2. A placement slot 11 is formed at the bottom of the main scraper 5, and screw holes 1 are evenly distributed at the top of the placement slot 11. 2.

A screw hole 3 16 is opened on the main scraper 5 and is coaxially set with screw hole 2 15. Screw hole 2 15 and screw hole 3 16 are fixedly installed by countersunk bolts.

[0026] To address the problems of difficult replacement and poor wear resistance of conveyor scrapers in existing technologies, this utility model patent adopts the following technical structure: several conveyor scraper assemblies 3 are evenly distributed within the scraper conveying channel 2. Each conveyor scraper assembly 3 includes a main scraper 5, a chain clamping plate 6, and a wear-resistant plate 7. A slot 11 is placed at the bottom of the main scraper 5, and limit blocks 13 are symmetrically arranged on the upper part of the chain clamping plate 6. One section of the double chain 4 is sleeved and installed around the limit block 13, and fixed by countersunk bolts through screw hole sleeve 14 and screw hole 12, thereby achieving the fixed installation between the chain clamping plate 6 and the main scraper 5. This completes the clamping and installation of the double chain 4 between the chain clamping plate 6 and the main scraper 5, enabling the conveyor scraper assembly 3 to be pulled by the double chain 4 to transport coal.

[0027] To achieve wear-resistant use of the conveyor scraper assembly 3, a wear-resistant plate 7 is installed on one side of the main scraper 5 in the sliding direction. One side of the wear-resistant plate 7 is provided with a second screw hole 15. The main scraper 5 is provided with a third screw hole 16 coaxially arranged with the second screw hole 15. The second screw hole 15 and the third screw hole 16 are fixedly installed by countersunk bolts to achieve fixed installation of the main scraper 5 and the wear-resistant plate 7, thereby increasing the wear resistance of the main scraper 5. When the wear-resistant plate 7 wears, only the wear-resistant plate 7 needs to be replaced, thus improving the utilization rate of the main scraper 5 and improving the timeliness of wear replacement.

[0028] In at least one embodiment, the main scraper 5 has an insertion groove 17 in the middle of the side facing its sliding direction.

This structure also enables rapid replacement of the wear-resistant plate 7 due to wear, which is beneficial to improving the efficiency of the mining conveyor.

[0030] In at least one embodiment, to ensure that the wear-resistant plate 7 can be quickly and securely installed on the main scraper 5, the two arc-shaped blocks 22 and the two arc-shaped inserts 23 are arranged in a horizontally rotationally symmetrical manner, and the two arc-shaped slots 24 and the two arc-shaped grooves 25 are also arranged in a horizontally rotationally symmetrical manner.

[0031] In at least one embodiment, an elongated through hole 31 is provided in the middle of the wear-resistant plate 7.
