[0042] Specifically, box 1 is connected with fixed plate 101 near the discharge end, dust collecting hood 8 extends upward near one end of fixed plate 101 and is slidably connected with fixed plate 101, two guide grooves 102 are provided on fixed plate 101, the upwardly extending portion of dust collecting hood 8 is connected with guide groove 102, thereby achieving vertical sliding connection with fixed plate 101, the fixed plate and the extension of one end of dust collecting hood 8 jointly block the smoke dust, so that the smoke dust can only pass from the bottom of dust collecting hood 8, further improving the smoke dust collection effect of dust collecting hood 8.

[0043] Further, the bottom end of the dust cover 8 away from the fixed plate 101 is rotatably connected with a baffle switch 10 for controlling the contraction of the telescopic column 9. In the specific implementation, the telescopic column 9 will continue to slowly extend downward, and after the baffle switch 10 contacts the material conveyed on the body 16 of the conveying belt, the telescopic column 9 will quickly contract by a set length.
