[0015] The present invention provides a mixing device for carp feed additive production by improvement, which has the following improvements and advantages compared with the prior art: First, the present invention arranges a scraper extrusion unit, and a motor drives a driving shaft to rotate. The rotation of the driving shaft drives a rotating tube, a sliding tube and a fixed tube to rotate through two bevel gears, so that the rotation of the scraper can scrape the residual material adhered to the inner wall of the box body onto the guide plate. The rotation of the driving shaft drives the cam to rotate. When the cam squeezes the strip plate to drive the connecting rod and the sliding piston to move downward, the sliding piston moves downward to squeeze the gas in the air storage chamber into multiple fixed tubes through the rotating tube and the sliding tube, so that the gas pushes the sliding rod and the extrusion plate to move, so that the extrusion plate contacts the guide plate.

The reciprocating movement of the reciprocating sleeve drives the fixed ring and the sliding tube and the fixed tube to move, so that the guide plate, the scraper and the V-shaped plate are moved, thereby improving the effect of turning, scraping and stirring the material.

[0017] Thirdly, the present invention arranges a scraping and extruding unit, and the reciprocating movement of the shaft sleeve drives the movement of the extruding rod. When the extruding rod moves upward and contacts the inclined rod, the extruding rod squeezes the inclined rod and drives the movable rod and the baffle to move outward. The movement of the movable rod drives the installed spring to stretch and elastically deform. The movement of the baffle opens the feed pipe, so that the material in the feed box enters the discharge box through the feed pipe, and then is discharged from the discharge port. When the extrusion rod moves downward away from the inclined rod, the installed spring drives the baffle to reset and close the feed pipe, so that intermittent feeding can be carried out, so that the material can be mixed more evenly. When the sliding piston moves downward, the gas in the inflation chamber can be squeezed into the jet head through the one-way air outlet pipe and sprayed out by the jet head. The sprayed gas blows away the material falling from the discharge port, thereby expanding the range of material falling and making the material mixing more even. BRIEF DESCRIPTION OF THE DRAWINGS
