Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a chain tightening adjustment component of a scraper conveyor and the scraper conveyor. Background Art

[0002] Scraper conveyor is a kind of winding body, as a continuous conveying machine with traction mechanism, mainly used for transportation in mining working face. Its traction mechanism is the scraper chain, and the bearing mechanism is the chute.

[0003] When the scraper is conveying, the scraper chain needs to bear the weight of the transported material. Long-term use will cause the chain to loosen, and the scraper chain cannot be used normally, affecting the transmission efficiency of the scraper chain. The prior art uses a chain tightening mechanism to adjust the tension of the scraper chain.

[0004] The current chain tightening mechanism of the scraper usually directly adjusts the position of the sprocket. For example, in the existing patent with patent number 202122574353.0 and patent name "A Feeding Scraper", the sprocket is moved by the tensioning screw to achieve chain tension. However, since only the position of the sprocket can be adjusted, the position of the end plate of the scraper cannot be adjusted, and it is easy for materials to accumulate at the end of the scraper, forming a material accumulation corner, which needs to be cleaned on time. If the cleaning is not timely, the materials may become moldy, affecting the quality of the materials. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a chain tightening adjustment component of a scraper machine and a scraper machine, so that the guide plate and the adjustment sprocket wheel move synchronously, so that materials cannot enter the material accumulation corner, and the materials in the material accumulation corner are prevented from being accumulated and moldy.

[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a tensioning chain adjustment assembly of a scraper machine, comprising a base frame and two side plates arranged at a relative interval, the bottoms of the two side plates are fixedly connected to the base frame, the two side plates are provided with strip guide holes extending along the two end directions thereof, the sides of the two side plates away from each other are provided with slides that can move along the two end directions of the side plates, an adjusting sprocket is provided between the two side plates, the adjusting sprocket is fixedly sleeved on the rotating shaft, the two ends of the rotating shaft respectively pass through the two strip guide holes and are rotatably connected to the two slides; a guide plate is provided between the two side plates, the sides of the two slides facing each other are fixedly connected to the two sides of the guide plate, the guide plate and the adjusting sprocket are arranged at intervals, an end plate is provided at one end of the two side plates, a plurality of screws are provided on the end plate, and the plurality of screws pass through and extend out of the end plate and are threadedly connected to the two slides.
