By arranging a scraping component, the effect of scraping off slag is achieved, and the slag is prevented from sticking to the scraper and affecting the slag scooping. At the same time, by arranging a cleaning component, the scraper after scraping can be cleaned by utilizing the principle of friction, and the cleaning effect is excellent.

[0027] Figure 1-3 The figure shows the overall structure of an anti-blocking slag scooping machine applicable to a pulverized coal furnace of the utility model. Figure 1-3 The main body of the anti-clogging slag scooping machine applicable to a pulverized coal furnace in this embodiment includes: a machine body 100, a driving assembly 200, a slag scooping assembly 300, a cleaning assembly 400 and a scraping assembly 500.

[0028] The driving assembly 200 serves as a power source to facilitate the slag collecting machine to collect slag. Specifically, the driving assembly 200 is arranged on the machine body 100. The driving assembly 200 includes a reducer 201 arranged at the front end of the machine body 100, a driving motor 202 arranged at the front end of the reducer 201, a rotating shaft 203 arranged at the rear side of the reducer 201, and a first gear 204 arranged on the rotating shaft 203. The rotating shaft 203 is rotatably connected to the machine body 100 through a bearing. During specific use, the driving motor 202 can be controlled to operate. The operating driving motor 202 can drive the rotating shaft 203 and the first gear 204 to rotate through the reducer 201, so that the first gear 204 drives the slag collecting assembly 300 to rotate and push the slag.

[0029] The slag scooping assembly 300 is used to transport slag. Specifically, the slag scooping assembly 300 includes a chain 301 arranged in the body 100 and a plurality of scrapers 302 arranged on the chain 301. The slag scooping assembly 300 also includes a transmission shaft 303 connected to the bearing of the body 100 and a second gear 304 arranged on the transmission shaft 303 and rotatably connected to the chain 301. During specific use, the rotating first gear 204 can drive the chain 301 and the plurality of scrapers 302 to rotate, and the rotating plurality of scrapers 302 can push the slag to transport the slag, and the chain 301 can drive the second gear 304 and the transmission shaft 303 to rotate, so that the second gear 304 and the transmission shaft 303 support the chain 301.

[0030] It is inevitable that the existing scraper 302 will be stuck with residue, and too much residue will affect the conveying of the scraper 302. In order to solve this problem, a cleaning component 400 is provided. Specifically, the cleaning component 400 includes a fixed plate 401 arranged on the top of the body 100, a cylinder 402 arranged on the top of the fixed plate 401, a fixed seat 403 arranged at the bottom of the cylinder 402, and a brush 404 arranged on the left side of the fixed seat 403. The fixed seat 403 is provided with a plurality of circular holes for installing the scraping component 500. During specific use, the cylinder 402 can be controlled to extend, and the extended cylinder 402 can drive the brush 404 to move downward through the fixed seat 403. The brush 404 can use the principle of friction to clean the scraper 302 after scraping, so as to thoroughly clean the residue.

[0031] The existing scraper 302 will inevitably be stuck with residue during the conveying process. Excessive residue will affect the conveying of the scraper 302 and there is a risk of clogging, which is not easy to use. In order to solve this problem, a scraping assembly 500 is provided. Specifically, the scraping assembly 500 includes a scraping seat 504 arranged on the fixed seat 403 and a scraper 506 arranged on the left side of the scraping seat 504.

The screw 501, the nut 502 and the spring 503 connected thereto form a group, and a number of groups are equidistantly arranged. In specific use, when the cylinder 402 extends to drive the scraping assembly 500 to move downward, since the spring 503 has a certain elastic potential energy, the inclined surface 505 of the scraper seat 504 can guide the scraper 506 to the right side of the scraper 302, and then the scraper 506 can be used to scrape the residue on the side of the scraper 302 to clean the residue and prevent the residue from affecting the use of the scraper 302. At the same time, the nut 502 can be rotated until it is completely separated from the screw 501. After separation, the scraping assembly 500 can be directly removed to facilitate replacement and cleaning of the scraping assembly 500.
