This solves the problem that it is inconvenient to operate when cleaning the residue on the inner wall of the discharge channel, which requires workers to reach into the discharge channel.

[0042] Specifically, a positioning component 204 is arranged on the top side of the outer end of channel A201;

[0043] Positioning assembly 204 includes a U-shaped block 2041, guide rods 2042, an L-shaped plate 2043, and a top plate 2044; the U-shaped block 2041 is fixed to the top side of the outer end of channel A201; wherein, the hole of the U-shaped block 2041 is fitted with the positioning plate 205 fixed to the top side of the outer end of channel B202; two guide rods 2042 are symmetrically fixed to the top side of the U-shaped block 2041; the transverse section of the L-shaped plate 2043 is sleeved on the two guide rods 2042; the top plate 2044 is fixed to... The top ends of the two guide rods 2042; among them, a spring 2045 is sleeved on the guide rod 2042 between the top plate 2044 and the transverse section of the L-shaped plate 2043. The two ends of the spring 2045 are fixedly connected to the top plate 2044 and the transverse section of the L-shaped plate 2043 respectively.
