Detailed Description

As shown in fig. 1-3, a dust collecting hopper 1 comprises a hopper shell, a cone core 2 arranged in the hopper shell and an adjusting device for driving the cone core 2 to move up and down.

The bucket shell includes fixed plate 3, establishes first casing 4 in fixed plate 3 bottom and establishes the conical second casing 5 in first casing 4 bottom, is equipped with feed inlet 6 and discharge gate 7 on the bucket shell, and discharge gate 7 is established in the bottom of second casing 5, and feed inlet 6 is seted up on the lateral wall of first casing 4, and awl core 2 is established in discharge gate 7 department, adjusts the opening size of discharge gate 7 through reciprocating of awl core 2.

The adjusting device comprises a worm gear mechanism 8 arranged in the bucket shell, a mounting seat 9 arranged on the outer side of the bucket shell, a horizontally arranged adjusting rod 10, a vertically arranged connecting rod 11 and a rotation stopping mechanism for preventing the connecting rod 11 from rotating; the worm and gear mechanism 8 is installed at the bottom of the fixed plate 3, the worm and gear mechanism 8 comprises a shell, a worm wheel and a worm, the end part of the worm is connected with one end of an adjusting rod 10, one end of the adjusting rod 10, which is far away from the worm, extends out of the bucket shell and is provided with a rotating handle 12, in addition, the adjusting rod 10 is also rotatably installed on an installation seat 9, an inner hole is formed in the middle position of the worm wheel, inner threads are formed in the hole wall of the inner hole, a connecting rod 11 comprises an outer thread section, a connecting section arranged at the bottom end of the outer thread section and a rotation stopping section 14 arranged at the top end of the outer thread section, the connecting rod 11 is in threaded connection with the inner hole of the worm wheel through the outer thread section, the rotation stopping section 14 of the connecting rod 11 is arranged above.
