Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.

In the description of the present invention, it should be understood that the orientation or positional relationship referred to in the description of the orientation, such as the upper, lower, front, rear, left, right, etc., is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

Referring to fig. 1 and 2, the utility model discloses a rotary grid slag extractor, which comprises a first support 10 and a second support which are used as bearing main bodies, wherein a conveying chain 21 is arranged between the first support 10 and the second support, a plurality of grid teeth 22 are arranged on the conveying chain 21 along the moving direction, and the conveying chain 21 circularly moves under the driving of a driving device. Fig. 1 is a cross-sectional view so that the first support 10 is temporarily visible, and in fact the second support has the same configuration as the first support 10 and is parallel to the latter.

The rotary grid slag extractor also comprises a cleaning roller. The cleaning roller includes motor, stack shell 31 and sets up a plurality of scrapers 32 in stack shell 31 week side, a plurality of scrapers 32 equidistant arrangement on same bus, the motor drives stack shell 31 is rotatory, stack shell 31 drives scrape 32 the swing and it is crisscross with the grid tooth 22 that corresponds to scrape 32, it is flexible lamellar body to scrape 32, it is close to scrape 32 the inboard of stack shell 31 is the narrow limit, it keeps away from to scrape 32 the outside of stack shell 31 is the broadside, the inboard width of scraping 32 is less than the clearance of two adjacent grid teeth 22 on the same bus, the outside width of scraping 32 is greater than the clearance of two adjacent grid teeth 22 on the same bus.

With particular reference to fig. 1, the wiper strip 32 is suitably bent back when it is rotated, in which process the narrower inner and middle sides of the wiper strip 32 first snap into between two adjacent grid teeth 22; the wider outer side of the scraping bar 32 then enters between two adjacent grid teeth 22, and after the barrel 31 continues to rotate, the outer side of the scraping bar 32 gradually separates from two adjacent grid teeth 22 (it can be seen in fig. 2 that the left and right sides of the scraping bar 32 need to be bent properly to be drawn out between two grid teeth 22), and the wider outer side of the scraping bar 32 is forcibly drawn out to play a role of deeply brushing the grid teeth 22.
