[0027] The equalizing device 4 includes a fixed slide 41 , a reduction motor 42 is arranged on the rear end face of the fixed slide 41 , and a connecting screw 43 is arranged at the output end of the reduction motor 42 , and a feeding sleeve 44 is threadedly slidably connected to the interior of the fixed slide 41 through the connecting screw 43 .

[0028] The fixed slide 41 and the loading sleeve 44 are both slidably connected to the inside of the sealing seat 31 through the sealing groove 36, which can effectively improve the stability of the subsequent sliding displacement of the fixed slide 41 and the loading sleeve 44 inside the sealing seat 31.

[0029] The top of the fixed slide 41 is fitted and connected with the bottom of the material distribution conduit 33, and a storage trough with an adjustable volume is provided between the loading sleeve 44 and the fixed slide 41.
