FIG. 1 is a schematic view of the present invention;

in the figure: a hopper body-1, a feeding pipe-2, a charging hopper-3 and an anti-sticking layer-4.

Detailed Description

Referring to fig. 1, the present invention provides a straight-edge vacuum hopper for preventing particles from being accumulated and bonded: comprises a bucket body 1;

the feeding pipes 2 fixedly penetrate through the inner side and the outer side of the hopper body 1 and are communicated with the extraction part;

a charging hopper 3 is fixedly arranged on the inner side of the hopper body 1, and the periphery of the top end of the charging hopper is in sealing fit with the inner wall of the hopper body 1, so that materials are pre-packaged and the sealing property is provided;

the inner walls of the hopper body 1 and the charging hopper 3 are respectively provided with an anti-sticking layer 4, so that the adhesion degree is reduced;

the inner wall of the charging hopper 3 is enclosed by a vertical edge and a bevel edge, the space of the inner wall of the charging hopper 3 is gradually reduced from top to bottom, and according to the above, the effect of collecting materials is ensured, the supporting stress to the materials is reduced, and the possibility of blockage is reduced.

Wherein the periphery of the top end of the charging hopper 3 is in transition connection with the inner wall of the hopper body 1 through an arc-shaped surface,
