Description

Technical Field

[0001] This utility model relates to the field of ore feeding and transportation technology in mining grinding systems, and in particular to a novel anti-jamming device for a feeding trolley. Background Technology

[0002] The feeding trolley is a front-end device in the grinding system, mainly serving as an intermediate transmission medium between conveying equipment such as the blast mill and belt conveyor, and the grinding equipment. As a mining production and transportation device, during feeding operation, the blast mill and belt conveyor sometimes experience uneven ore conveying and excessive load, leading to frequent jamming and full buckets in the feeding trolley. Sometimes, it is necessary to frequently stop the mill, blast mill, and belt conveyor to clear the jammed ore, affecting production.

[0003] Based on the phenomenon of feed trolley jamming on site, a feed trolley anti-jamming device is designed to prevent feed trolley jamming, reduce grinding downtime and maintenance labor time, save costs, improve production efficiency, and ensure safe operation of equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel anti-jamming device for feeding trolleys.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel anti-jamming device for a feeding trolley includes a feeding trolley and an anti-jamming device. The anti-jamming device is installed on the side of the feeding trolley. A structural steel plate is fixedly installed on the side wall of the feeding trolley. Two angle steels are fixedly installed on the structural steel plate. A photoelectric switch is fixedly installed on each angle steel. The two photoelectric switches are arranged in parallel and opposite directions. A wear-resistant liner is fixedly installed on the inner wall of the feeding trolley.

[0007] Preferably, a protective steel plate is fixedly installed on the wear-resistant liner, the structural steel plate and the wear-resistant liner are connected together, and a displacement rod is movably installed between the structural steel plate and the wear-resistant liner, with the displacement rod located below the protective steel plate.

[0008] Preferably, a hinge is fixedly installed on the structural steel plate, and a movable steel plate is fixedly installed on the movable end of the hinge, and the hinge is used to rotate the movable steel plate.

[0009] Opposite arrangement of photoelectric switches: The flow of ore on the side of the feeding trolley is monitored in real time by two parallel and opposite photoelectric switches. When the ore accumulates and jams in the hopper, the movable steel plate is driven to rotate by the displacement rod, which obstructs the photoelectric signal and forms a precise non-contact detection, avoiding the lag and wear problems of traditional mechanical contact detection.

[0010] Rapid response control: When the through signal is blocked, the iron plate machine and belt conveyor are immediately stopped, the ore feeding path is cut off, the ore is prevented from accumulating, the hopper jamming failure is stopped from the source, and the safety and reliability of equipment operation are significantly improved.

[0011] Multi-layer protective structure:

[0012] The combination of wear-resistant inner lining plates and protective steel plates can effectively resist the impact and friction when ore falls, reduce wear on the equipment body, and extend service life.

[0013] The structural steel plate and the wear-resistant liner are movably connected by a displacement rod. When a jam occurs, the movable steel plate is allowed to be displaced by the ore pressure, forming a buffer protection and avoiding structural damage caused by rigid collision.

[0014] Hinged moving steel plate: The moving steel plate can rotate flexibly through the hinge, which not only ensures that it does not affect the flow of ore during normal feeding, but also responds quickly to the drive of the displacement rod when the bucket is jammed, forming a reliable signal triggering mechanism that combines flexibility and stability.

[0015] Proactive prevention of bucket jamming: Through real-time detection and immediate shutdown, long-term downtime for maintenance caused by bucket jamming is avoided, reducing the frequency of manual bucket cleaning and equipment damage, and lowering maintenance costs; Automated control process: The mechanical structure (displacement rod, movable steel plate) is combined with electrical control (through-beam switch, equipment linkage) to form an automated closed loop of "detection-trigger-shutdown", which improves the intelligence level of the feeding system and adapts to the needs of industrial automated production.

[0016] Modular design: The anti-jamming device is installed as an independent module on the side of the feeding trolley and is fixed to the trolley body by angle steel and structural steel plates. It does not change the original main structure of the equipment and is convenient for the transformation and upgrading of existing production lines.

[0017] Highly adaptable: The spacing between the through-beam switches, the size of the movable steel plate, and the stroke of the displacement rod can be adjusted according to different specifications of the feeding trolley, making it suitable for conveying various ore materials and possessing broad engineering application value.

[0024] like Figures 1-4 As shown, the overall concept of the technical solution in this application embodiment is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a novel anti-jamming device for a feeding trolley, comprising a feeding trolley 11 and an anti-jamming device 12. The anti-jamming device 12 is installed on the side of the feeding trolley 11. A structural steel plate 7 is fixedly installed on the side wall of the feeding trolley 11. Two angle steels 6 are fixedly installed on the structural steel plate 7. A photoelectric switch 1 is fixedly installed on each angle steel 6. The two photoelectric switches 1 are arranged in parallel and opposite directions. A wear-resistant liner 8 is fixedly installed on the inner wall of the feeding trolley 11.

[0026] A protective steel plate 5 is fixedly installed on the wear-resistant liner 8. The structural steel plate 7 and the wear-resistant liner 8 are connected together. A displacement rod 4 is movably installed between the structural steel plate 7 and the wear-resistant liner 8, and the displacement rod 4 is below the protective steel plate 5. A hinge 3 is fixedly installed on the structural steel plate 7. A movable steel plate 2 is fixedly installed at the movable end of the hinge 3, and the hinge 3 is used to rotate the movable steel plate 2. The displacement rod 4 can drive the movable steel plate 2. The movable steel plate 2 can block the signal of the photoelectric switch 1. After the photoelectric switch 1 blocks the signal, the signal controls the iron plate machine and the belt conveyor 9 to stop running. The belt conveyor 9 stops feeding ore 10. The feeding trolley 11 can promptly prevent the ore 10 from continuing to accumulate and jam in the bucket. The anti-jamming device 12 on the feeding trolley 11 plays a technical role. This utility model solves the problem of bucket jamming caused by the feeding trolley feeding ore in the prior art.

[0027] The through-beam switch 1 is a slotted photoelectric switch with IP67 protection rating and an adjustable detection distance of 50-100mm; the displacement rod 4 is made of 304 stainless steel and has a designed stroke of 30±2mm. The through-beam switch 1 is electrically connected to the belt conveyor 9 through a PLC controller.

[0028] Opposite arrangement of photoelectric switches: The flow of ore on the side of the feeding trolley is monitored in real time by two parallel and opposite photoelectric switches. When the ore accumulates and jams in the hopper, the movable steel plate is driven to rotate by the displacement rod, which obstructs the photoelectric signal and forms a precise non-contact detection, avoiding the lag and wear problems of traditional mechanical contact detection.

[0029] Rapid response control: When the through signal is blocked, the iron plate machine and belt conveyor are immediately stopped, the ore feeding path is cut off, the ore is prevented from accumulating, the hopper jamming failure is stopped from the source, and the safety and reliability of equipment operation are significantly improved.

[0030] Multi-layer protective structure:

[0031] The combination of wear-resistant inner lining plates and protective steel plates can effectively resist the impact and friction when ore falls, reduce wear on the equipment body, and extend service life.

[0032] The structural steel plate and the wear-resistant liner are movably connected by a displacement rod. When a jam occurs, the movable steel plate is allowed to be displaced by the ore pressure, forming a buffer protection and avoiding structural damage caused by rigid collision.

[0033] Hinged moving steel plate: The moving steel plate can rotate flexibly through the hinge, which not only ensures that it does not affect the flow of ore during normal feeding, but also responds quickly to the drive of the displacement rod when the bucket is jammed, forming a reliable signal triggering mechanism that combines flexibility and stability.

[0034] Proactive prevention of bucket jamming: Through real-time detection and immediate shutdown, long-term downtime for maintenance caused by bucket jamming is avoided, reducing the frequency of manual bucket cleaning and equipment damage, and lowering maintenance costs; Automated control process: The mechanical structure (displacement rod, movable steel plate) is combined with electrical control (through-beam switch, equipment linkage) to form an automated closed loop of "detection-trigger-shutdown", which improves the intelligence level of the feeding system and adapts to the needs of industrial automated production.

[0035] Modular design: The anti-jamming device is installed as an independent module on the side of the feeding trolley and is fixed to the trolley body by angle steel and structural steel plates. It does not change the original main structure of the equipment and is convenient for the transformation and upgrading of existing production lines.

[0036] Highly adaptable: The spacing between the through-beam switches, the size of the movable steel plate, and the stroke of the displacement rod can be adjusted according to different specifications of the feeding trolley, making it suitable for conveying various ore materials and possessing broad engineering application value.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
