Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a universal chain separation tongue plate for scraper conveyors. Background Art

[0002] Scraper conveyor is a continuous transport equipment. This conveyor puts the material in the conveying trough and uses the chain to pull the scraper to push the material to move, so as to transport the material. There is a guard plate, also called a tongue plate, at the head of the scraper conveyor, which plays a role in lifting and guiding the scraper when the scraper chain separates from the sprocket.

[0003] The tongue plate of the existing scraper conveyor is welded to the conveying trough box. During operation, the scraper conveyor's upper chain drives the scraper and will always be in contact and friction with the tongue plate. When the scraper conveyor is operating normally, the chain is loosest at the separation point of the upper chain and the sprocket. The gap between the tongue plate and the sprocket can easily get the chain stuck, causing a chain break accident (the conventional solution is to install a chain picker in the middle of the tongue plate and the toothed wheel to avoid the chain and tongue plate from getting stuck). However, the chain picker is easy to fall off and wear, so it often does not work. At the same time, the chain and the tongue plate are in contact and friction, and both are worn, reducing their service life and increasing the investment in manpower and material resources. Utility Model Content

[0004] In view of the above problems, the utility model proposes a universal chain separation tongue plate for a scraper conveyor to solve the above problems.

[0005] The utility model is implemented as follows: a universal chain separation tongue plate for a scraper conveyor comprises a conveying trough and a tongue plate body, the inner wall of the conveying trough is rotatably connected with a rotating shaft, the outer wall of the rotating shaft is fixedly connected with two symmetrically distributed turntables, the outer walls of the two turntables are fixedly connected with sprockets, gaps are left between the front and rear end surfaces of the tongue plate body and the front and rear end surfaces inside the conveying trough, two support rods are fixedly connected between the inner walls of the conveying trough, the upper end surfaces of the two support rods are fixedly connected with two symmetrically distributed sleeves, the lower end surface of the tongue plate body is fixedly connected with four symmetrically distributed first sliding rods, the four first sliding rods are respectively slidably connected with four sleeves, and a lifting mechanism for lifting the tongue plate body is provided inside the conveying trough.

[0006] In order to facilitate the lifting and lowering of the tongue plate body, the universal chain separation tongue plate of the scraper conveyor of the utility model is preferably selected, and the lifting mechanism includes a threaded rod, a second sliding rod, two sliders and two connecting rods. The threaded rod is rotatably connected to the inner wall of the conveying trough, and the sliding rod is fixedly connected to the inner wall of the conveying trough. The two sliders are respectively threadedly connected to the two ends of the threaded rod and slidably connected to the second sliding rod. The upper ends of the two connecting rods are hinged to the lower end surface of the tongue plate body, and the lower ends of the two connecting rods are respectively hinged to the two sliders.

[0007] In order to facilitate the two sliders to move relative to or away from each other when the threaded rod rotates, it is preferred that the thread directions of the two ends of the threaded rod are opposite to each other as the universal chain separation tongue plate of the scraper conveyor of the utility model.

[0008] In order to facilitate the rotation of the threaded rod, as a preferred embodiment of the universal chain separation tongue plate of the scraper conveyor of the utility model, the front end of the threaded rod extends to the outside of the conveying trough and is fixedly connected with a rotating handle.

[0009] In order to facilitate the coordination between the tongue plate body and the rotating shaft and the rotating disk, the tongue plate body is preferably in a convex shape as the universal chain separation tongue plate of the scraper conveyor of the utility model.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The universal chain separation tongue plate of the scraper conveyor is modified on the basis of the original tongue plate. The tongue plate that lifts the chain part is cut off, and the tongue plate body is supported by the support rod, sleeve, first slide bar and lifting mechanism, so that the tongue plate body does not contact the chain. This tongue plate body only lifts the scraper, which effectively avoids the chain jamming phenomenon between the sprocket and the tongue plate body when the chain is loose. Because the tongue plate body does not contact the chain, the wear problem of the chain and the tongue plate body is solved, and the use effect is good. Through the cooperation of the threaded rod, the second slide bar, the slider and the connecting rod, the two sliders can be driven to move relative or opposite to each other along the second slide bar, thereby driving the tongue plate body to rise and fall through the connecting rod, which is convenient for freely adjusting the height of the tongue plate body according to the tightness of the chain, so that the tongue plate body can better lift the scraper.

This tongue plate body 7 only lifts the scraper, which effectively avoids the chain jamming phenomenon between the sprocket 4 and the tongue plate body 7 when the chain is loose. Because the tongue plate body 7 does not contact the chain, the wear problem of the chain and the tongue plate body 7 is solved, and the use effect is good.

[0020] As a technical optimization scheme of the utility model, the lifting mechanism includes a threaded rod 9, a second sliding rod 10, two sliders 11 and two connecting rods 12. The threaded rod 9 is rotatably connected to the inner wall of the conveying trough 1, the sliding rod is fixedly connected to the inner wall of the conveying trough 1, the two sliders 11 are respectively threadedly connected to the two ends of the threaded rod 9 and are slidably connected to the second sliding rod 10, the upper ends of the two connecting rods 12 are hinged to the lower end surface of the tongue plate body 7, and the lower ends of the two connecting rods 12 are respectively hinged to the two sliders 11.
