Hydraulic tensioning type single-layer wet type scraping plate slag dragging machine

Abstract

The invention provides a hydraulic tensioning type single-layer wet type scraping plate slag dragging machine. The hydraulic tensioning type single-layer wet type scraping plate slag dragging machinecomprises a groove body; the groove body comprises a horizontal groove body and an oblique groove body; the oblique groove body is connected with the horizontal groove body into a whole; emergent slagoutlets are formed in the side wall of the horizontal groove body; manual inserting plate doors are arranged at the upper end of the horizontal groove body; a transmission wheel and a tensioning wheel are correspondingly arranged at the two ends of the groove body; the transmission wheel is arranged on the oblique groove body; an upper guide wheel and a lower guide wheel are arranged in the groove body; the transmission wheel and the tensioning wheel are connected with chain scraping plates; chain scraping plates are tensioned by the upper guide wheel and the lower guide wheel; the transmission wheel is connected with a speed-reducing motor; and a hydraulic tensioning device is arranged at the lower end of the tensioning wheel. With the adoption of the hydraulic tensioning type single-layer wet type scraping plate slag dragging machine, slag scraping and return stroke chains are not abraded, operation tracks of the chains are accurate, and the chains are not separated or clamped.

Description

technical field [0001] The invention relates to a scraper slag remover, in particular to a hydraulically tensioned single-layer wet scraper slag remover. Background technique [0002] The transmission chain in the old-fashioned wet scraper scraper generally adopts plate roller chain, and the scraper is a simple scraper made of channel steel without guide wheels. The chain tensioning device is locked by a rotating screw rod. The original support chain The device is a skateboard type, and its friction mode is sliding friction, and the friction force is large. This structure shows that when the chain is running, the running mode of the slide plate and the chain is sliding, and the friction force is large, which causes the chain rollers to wear quickly. It is easy to cause the chain to get stuck, unchained, or broken, and the service life does not exceed half a year. Disadvantages of the old-fashioned wet scraper scraper: ①The chain is always worn during scraping and return, so...

Problems solved by technology

[0002] The transmission chain in the old-fashioned wet scraper scraper generally adopts plate roller chain, and the scraper is a simple scraper made of channel steel without guide wheels. The chain tensioning device is locked by a rotating screw rod. The original support chain The device is a skateboard type, and its friction mode is sliding friction, and the friction force is large. This structure shows that when the chain is running, the running mode of the slide plate and the chain is sliding, and the friction force is large, which leads to fast wear of the chain rollers.

It is easy to cause the chain to be stuck, unchained, or broken, and the service life is no more than half a year

Disadvantages of the old-fashioned wet scraper scraper: ①The chain is always worn during scraping and return, so the chain wears quickly; ②Since the friction method is sliding friction, and the wear direction is unidirectional wear, not circumferential wear; ③No The chain guide wheel has only the guide track, so the guide is not accurate, and it is easy to cause the chain to be stuck, unchained, or broken; ④The chain tensioning device is locked by a rotating screw. This structure shows that as long as the chain is stretched, it cannot be adjusted in time by manual labor. will cause off-chain

Disadvantages of the tensioning method of the tail tensioning device of the old-fashioned scraper scraper: 1. None of the above three tensioning methods can automatically provide a constant tension for the scraper chain, although the spring tensioning method can Tensioned, but with less spring force as the spring elongates

2. The above three tensioning methods need to be manually tensioned with the elongation of the chain, which is time-consuming and laborious, and the tensioning height on the left and right sides is different during the tensioning process, which is not conducive to the operation of the equipment
