[0021] The cam 306 is provided on the locking cam 305 to lock the locking cam 306. The cam 306 is provided on the locking cam 305 to lock the locking cam 306.

[0022] In the embodiment, an arch plate 4 is provided on the slag discharger body 1, and an arch brush plate 402 is provided below the horizontal plate of the arch plate 4. Brushes 405 are evenly provided on the inner surface of the arch brush plate 402, and the bristles 405 are in contact and adapted with the ash pushing plate 2. An electric telescopic rod 401 is connected between the top surface of the arch brush plate 402 and the bottom surface of the horizontal plate of the arch plate 4. Cross bars 403 are symmetrically fixed at both ends of the arch brush plate 402, and the cross bars 403 are inserted into the vertical plates of the arch plate 4.

At this time, the spring is in a compressed state, and the horizontal bar 304 is in the installation groove 303. After it is fully inserted, the spring is stretched, and the horizontal bar 304 pops out and slides into the through hole 203, so that the connection between the trapezoidal block 302 and the trapezoidal cover 202 is completed, and then the protective cover 306 slides down along the limiting vertical rod 305 until it touches The two magnetic blocks 204 are attracted to each other by being squeezed to the trapezoidal block 302, and the installation is simpler and faster. The limiting U-shaped plate 3 plays a role of limiting and stabilizing the ash pushing plate 2. When sweeping and brushing operations are required, the ash pushing plate 2 is rotated to stop just below the arch brush plate 402, and the electric telescopic rod 401 is controlled to stretch. At this time, the arch brush plate 402 descends, so that the bristles 405 sweep and brush both sides of the ash pushing plate 2, which is convenient for regular cleaning of the ash pushing plate 2 to avoid a lot of ash sticking to one side of the ash pushing plate 2, affecting the ash pushing operation.
