Description

Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a mining belt conveyor with anti-jamming function. Background Art

[0002] Belt conveyors for coal mines mainly refer to belt conveyors used in coal mining, production, transportation and processing.

[0003] China Authorization Announcement No. CN210762802U discloses a mining conveying mechanism for preventing material from getting stuck, comprising a supporting bottom bar and a motor base, wherein the tail end of the supporting bottom bar is fixedly mounted with a supporting long vertical bar, the head end of the supporting bottom bar is fixedly mounted with a supporting short vertical bar, the right side of the supporting short vertical bar is movably mounted with a first conveying roller, the top end of the supporting long vertical bar is fixedly mounted with a supporting diagonal bar, the head end of the supporting diagonal bar is fixedly connected to the supporting short vertical bar, the tail end of the supporting diagonal bar is fixedly connected to a supporting cross bar, and the left end of the supporting cross bar is movably mounted with a second conveying roller. The mining conveying mechanism for preventing material from getting stuck is provided with an inclined roller, and the conveyor belt pressed into an arc shape can ensure that the ore is not easy to fall, greatly enhancing the safety factor. A ball bearing is provided between the inclined roller and the fixed rod, which can greatly avoid the problem of fine sand and gravel in the mine floating to the connection between the inclined roller body and the fixed rod causing blockage at the connection, greatly enhancing work efficiency, while increasing service life and practicality.

[0004] However, this device has the following drawbacks: When conveying coal, due to the wet surface of the coal, some of the coal will adhere to the conveyor belt when it contacts it. If the coal on the conveyor belt is not cleaned promptly, a large amount of coal will adhere to the conveyor belt over time, causing the coal to accumulate on the conveyor belt. The accumulated coal is likely to fall onto the rollers, causing the rollers to become stuck, resulting in a material jam. To address these drawbacks, we propose a mining belt conveyor that is anti-jamming. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-4 The utility model provides a technical solution: an anti-jamming mining belt conveyor, comprising: a belt conveyor body, an anti-jamming structure and a transmission structure.

[0030] See Figure 1The belt conveyor body includes a base 10, a conveyor belt 11, a roller 12 installed on the upper surface of the base 10, and a driving structure arranged on the surface of the base 10 for driving the conveyor belt 11 to rotate. The driving structure includes a driving roller 40 and a driven roller 41 respectively rotatably installed on both sides of the base 10, and a motor 42 fixedly installed on the back of the base 10 for driving the driving roller 40 to rotate. The driving roller 40 and the driven roller 41 are connected by the conveyor belt 11. The driving motor 42 can drive the driving roller 40 to rotate, and the transmission of the conveyor belt 11 can drive the driven roller 41 to rotate, so that the conveyor belt 11 can be used to transport coal.

[0031] See Figure 2 The anti-stuck material structure includes a scraper assembly arranged on the surface of the base 10, and a conveying assembly arranged below the scraper assembly for transporting coal.

[0032] See Figure 2 The scraper assembly includes a support frame 20 fixedly mounted on the surface of the base 10, a scraper 21 fixedly mounted on the upper surface of the support frame 20, and a tensioning wheel component arranged on the surface of the base 10 for driving the conveyor belt 11 close to the scraper 21.

[0033] See Figure 2-4 The tensioning wheel component includes two support plates 50 fixedly mounted on the inner wall of the base 10, through holes opened on the surfaces of the two support plates 50, a guide rod 51 slidably mounted on the inner wall of the through hole, and a tensioning wheel 52 rotatably mounted at the lower end of the guide rod 51. The scraper 21 is located between the two support plates 50, and the scraper 21 is located directly above the material receiving barrel 30.

[0034] A limit plate 54 is fixedly installed on the upper end of the guide rod 51, and the limit plate 54 can prevent the guide rod 51 from escaping from the through hole. A compression spring 53 is sleeved on the surface of the guide rod 51, and one end of the compression spring 53 is fixedly connected to the lower surface of the support plate 50, and the other end of the compression spring 53 is fixedly connected to the upper surface of the tensioning wheel 52.

[0035] The compression spring 53 can drive the tensioning wheel 52 to contact the conveyor belt 11 and make the conveyor belt 11 always contact the scraper 21. When the driving structure drives the conveyor belt 11 to rotate, the scraper 21 can be used to scrape off the coal attached to the conveyor belt 11, thereby avoiding a large amount of coal adhering to the conveyor belt 11 and causing coal accumulation, and further avoiding the defect of coal falling and jamming the roller 12 due to coal accumulation on the conveyor belt 11.

[0036] See Figure 2The conveying assembly includes a material receiving barrel 30 fixedly mounted on the lower surface of the support frame 20, and a spiral auger 31 rotatably mounted on the inner wall of the material receiving barrel 30, and a feed trough is provided at the upper end of the material receiving barrel 30. When the scraper 21 scrapes the coal on the conveyor belt 11, the coal will enter the material receiving barrel 30 along the feed trough.
