the inclined planes of the two metal blocks at the bottom of one transverse rod are opposite to the inclined planes of the metal blocks at the bottom of the other transverse rods in direction, and after the horizontal rotary mechanism rotates for a circle, the position of the sliding door in the damping sliding groove moves to an initial state under the action of the metal blocks.
The working principle of the grading adjusting device is that a fish containing area is formed between each sliding door and the vertical baffle on one side, and the gap between each sliding door and the vertical baffle on the other side is smaller than the size of the minimum screened live fish. Therefore, when the live fish enters the horizontal rotary mechanism from the fish feeding hopper, the live fish can only enter a fish containing area formed by the sliding door and the vertical baffle.

Under the action of the nut adjusting mechanism, the sliding distance of the horizontal rod of the sliding door on the inclined surface of the metal block is adjusted along with the nut adjusting mechanism, so that the opening distance between the sliding door and the vertical baffle is adjusted. Because the width of the metal block is larger than that of the angle steel and the outer side surface of the metal block is flush with the angle steel, the two ends of the horizontal rod cannot touch the angle steel when sliding on the inclined surface of the metal block.
Further, in order to simplify the shape of the metal block, the metal block is shaped as an inverted right triangular prism.
Further, the number of the cross rods is 4.

Preferably, the sliding door 14 has a convex shape as shown in fig. 9, and the width of the lower end of the sliding door is equal to the width of the horizontal bar 14 a. Referring to fig. 4 and 6, a fish holding area is formed between each sliding door 14 and the vertical baffle 13 on one side, and the gap between the sliding door and the vertical baffle on the other side is smaller than the size of the smallest live fish to be screened, so that the live fish can be prevented from leaking from the gap. Preferably, the top of the sliding door 14 is higher than the top of the vertical baffle 13.
The damping spout can adopt the mode of at spout internally mounted friction material to make, and when the sliding door contacted metal block inclined plane, the drive power of motor was greater than friction damping, forces the sliding door to remove along the damping spout, and through the metal block after, the friction damping of spout self guarantees that the sliding door keeps former gesture unchangeable.
Continuing to refer to fig. 1, fig. 2 and fig. 7, 4 cross bars 4 are uniformly arranged on the frame 2 above the horizontal swing mechanism along the radial direction of the swing plane, a metal block 5 with an inclined plane is respectively installed at the bottom of each cross bar near the inner and outer cylinder walls, the distance between the two metal blocks is less than the length of the horizontal bar, the inclined plane of the metal block is over against the rotation direction of the horizontal swing mechanism, when the sliding door rotates to the metal block along with the horizontal swing mechanism, the two ends of the horizontal bar slide along the inclined plane of the metal block to drive the two sides of the sliding door to synchronously move in the damping sliding groove.
As shown in fig. 7 and 8, the inclined planes of the two metal blocks at the bottom of one cross bar are opposite to the inclined planes of the metal blocks at the bottom of the other cross bars, and after one rotation of the horizontal slewing mechanism, the position of the sliding door in the damping chute is moved to the initial state under the action of the metal blocks.

Every time the sliding door passes through a group of metal blocks, the gap between the sliding door and the vertical baffle plate is changed once, so that the grading of multiple groups of live fish sizes can be realized through the multiple groups of metal blocks. The damping spout can adopt spout internally mounted friction material to make, and when the sliding door contacted metal block inclined plane, the drive power of motor was greater than friction damping, forces the sliding door to remove in the damping spout, and through the metal block back, the friction damping of spout self guarantees that the sliding door keeps former gesture unchangeable. During the rotation process of the horizontal swing mechanism, the live fish falls into the corresponding collecting hopper 7 below from the opening between the sliding door and the vertical baffle. Because the inclined plane setting direction of the metal block at the bottom of one cross rod is opposite to the inclined plane direction of the metal blocks at the bottoms of other cross rods, the height of the sliding door is restored to the initial state after the sliding door rotates for a circle, and then the next round of live fish grading screening is carried out.
