Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mining equipment, and particularly relates to a wear-resistant groove of a scraper transfer machine. BACKGROUND

[0002] The scraper transfer machine is used in the transportation roadway of a high-efficiency and high-yield fully-mechanized coal mining face, and the two ends of the scraper transfer machine are connected with the tail of a conveyor and a belt conveyor respectively, so that the coal transported by the scraper conveyor of the fully-mechanized coal mining face can be lifted from the bottom of the roadway and then transferred to the belt conveyor, and once the scraper transfer machine fails, the continuity of the use of the scraper transfer machine will be affected, and the coal mine production will be greatly influenced.

[0003] The groove and the protruding groove of the scraper transfer machine are important components of the scraper transfer machine, which are used to lift the coal output by the scraper conveyor at a low position to a high position, and then the coal is transported to the belt conveyor through the head of the transfer machine to complete the transportation of the coal, and the middle plate and the bottom plate are key components of the groove and the protruding groove, and since the groove and the protruding groove are at the inflection point of the slope and the straight line transportation, the scraper chain is in close contact with the middle plate and the bottom plate during the operation of the scraper chain, which causes the abrasion of the middle plate and the bottom plate, reduces the service life of the groove and the protruding groove, and directly affects the production efficiency of the coal mining face and the coal production. SUMMARY

[0004] The utility model discloses a wear-resistant groove of a scraper transfer machine which overcomes the defects of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model takes the technical scheme: a wear-resistant groove of a scraper transfer machine, which comprises a groove body, the groove body is composed of a protruding groove and a groove at two ends and a chute connecting them, a middle plate is arranged in the middle of the groove body, and a bottom plate is arranged at the bottom of the groove body, a chain drives a scraper to pass through the surface of the middle plate, and then passes through the back of the middle plate and the surface of the bottom plate through rotation, characterized in that: a front bottom plate is arranged at the bottom of the protruding groove, and a front middle plate is arranged at the middle of the protruding groove; a middle bottom plate is arranged at the bottom of the chute, and a middle middle plate is arranged at the middle of the chute; a rear bottom plate is arranged at the bottom of the groove, and a rear middle plate is arranged at the middle of the groove; the thickness of the front bottom plate and the rear bottom plate is 5-10 mm larger than that of the middle bottom plate; the thickness of the front middle plate and the rear middle plate is 5-10 mm larger than that of the middle middle plate; a wear-resistant layer is welded on the surface chain channel area of the front middle plate and the front bottom plate, and a wear-resistant layer is welded on the back of the rear middle plate and the surface chain channel area of the rear bottom plate.

[0006] The connecting end of the front bottom plate and the middle bottom plate and the connecting end of the rear bottom plate and the middle bottom plate are machined into bevels; the connecting end of the front middle plate and the middle middle plate and the connecting end of the rear middle plate and the middle middle plate are machined into bevels, so that they are smoothly connected.

[0007] The thickness-to-length ratio of the bevel is 1:10-15.

[0008] The wear-resistant layer has a thickness of 3-5mm and a width of 50-100mm.

[0009] The utility model discloses the beneficial effect is: the thickness of the middle plate and the bottom plate of convex slot and recess has been increased, and the groove is processed at the connecting place, guarantees the smooth transition of the scraper. At the same time, the wear-resistant layer is welded on the working surface of the middle plate and the bottom plate of the scraper chain close to the recess and the convex slot, the wear resistance of the middle plate and the bottom plate is enhanced, the service life of the concave and convex groove of the transfer machine is prolonged, the coal mining cost is reduced, and the working face production efficiency is improved.
