Grading adjusting device of live fish grading screening machine

Abstract

The invention relates to a grading adjusting device of a live fish grading screening machine. The grading adjusting device comprises a horizontal rotation mechanism, wherein the horizontal rotation mechanism comprises an inner cylinder wall, an outer cylinder wall, a vertical blocking plate and a slide door; the vertical blocking plate and the slide door are arranged between the inner cylinder wall and the outer cylinder wall; the part, corresponding the slide door, of each of the inner cylinder wall and the outer cylinder wall is respectively provided with a damping slide groove; both sides of the slide door are inserted into the damping slide grooves; a machine frame is uniformly distributed with N transverse rods above the horizontal rotation mechanism; two metal blocks with slopes arerespectively arranged at the bottom part of each transverse rod; when the horizontal rotation mechanism is rotated to the metal blocks, the slide door is driven to move in the damping slide grooves; the direction of the slope of the metal block at the bottom part of one transverse rod is opposite to the direction of the slope of the metal block at the bottom of other transverse rod. The grading adjusting device has the advantages that under the cooperation function of the slide door and the metal blocks, the gap between the slide door and the vertical blocking plate can be changed; the structure is simple, the generation rate of faults is reduced, and the grading efficiency of live fishes is improved.

Description

technical field [0001] The invention relates to a grading adjustment device for a sliding door of a live fish grading and screening machine, and belongs to the technical field of live fish size grading and screening. Background technique [0002] In the Chinese invention patent application with the application publication number CN 107484809A published on December 19, 2017, the applicant proposed a live fish grading and screening machine. The working principle is that when the horizontal rotary mechanism starts to rotate, the cam mechanism Under the action of the cam adjustment plate, it rotates a fixed angle, and the cam mechanism acts on the spring return mechanism, so that the spring return mechanism drives the corresponding adjustment door to rotate synchronously, so that a certain angle gap is formed between the adjustment door and the grille, and the movement The fish slides out from the gap and enters the fish receiving bucket. The above application realizes rapid an...

Problems solved by technology

However, it has been found in use that due to the many parts of the cam mechanism and the spring return mechanism, the structure is complex and the manufacturing cost is high, and if the cam mechanism or the spring return mechanism breaks down, it will affect the rotation of the adjustment door and directly affect the classification of live fish carry out
