Problems solved by technology

[0002] There are many types of material conveying equipment, such as belt conveyors, bucket elevators, screw conveyors, scraper machines, etc. Among them, there are also many kinds of scraper machines. Because the temperature of the upgraded coal is from 300°C, water is gradually added to cool and humidify to a temperature of 60°C during the transportation process, the scraper machine as a whole, especially the roller chain, must have thermal expansion and contraction, and the chain will appear loose and tight accordingly, and the chain is too tight It will accelerate the wear of the chain and consume more power at the same time. If the chain is too loose, the chain will jump or get stuck, and the material transportation will not be carried out normally. For this reason, many companies use the manual adjustment of the screw nut to adjust the tightness of the chain. There are several problems with this adjustment method: first, whether the adjustment is tight or loose, I have no idea
Tight adjustment may accelerate chain wear, increase power consumption, and even break the chain; if the adjustment is too loose, chain jumping may occur, and it cannot work normally. Cracks, serious deformation of the chain, and severe chain jamming
The second is that the adjustment time cannot be synchronized with the tightness of the chain, and the above phenomenon also occurs.
[0005] However, it is difficult for the above two patents to provide a constant pulling force, and their structures are not suitable for high-temperature scraper machines, and still cannot solve the above-mentioned problems

Abstract

The invention discloses a high-temperature scraper machine. The high-temperature scraper machine comprises a machine head, a middle box body, a machine tail, a rolling wheel chain and a scraper blade, wherein the scraper blade is installed on the rolling wheel chain; the machine tail comprises a tail shell; the inner walls of the two sides of the tail shell are each provided with a guide sliding chute; each chain wheel sliding plate is arranged in the corresponding guide sliding chute; each chain wheel sliding plate is provided with a bearing hole; the two ends of a center shaft of a tail chain wheel are each provided with a bearing; each bearing is arranged inside the bearing hole of the corresponding chain wheel sliding plate; the chain wheel sliding plates are connected with a cross bar through a first connecting mechanism; and the cross bar is connected with a chain tensioning mechanism through a second connecting mechanism. According to the scraper machine disclosed by the invention, the position of the tail chain wheel can be adjusted automatically so that the tensioning force of the rolling wheel chain is effectively controlled; the level, on tightness control of the rolling wheel chain under a high-temperature state, of the coal machine equipment manufacturing industry is increased; and by controlling the tensioning force, the rolling wheel chain is always kept in a most suitable state, equipment faults are reduced, and high-efficiency and high-yield running of the scraper machine is guaranteed.
