Description

Technical Field

[0001] The invention relates to the technical field of saury fishing, and in particular to a shaft-rotating saury fish body primary sorting machine. Background Art

[0002] The annual output of Pacific saury in the Northwest Pacific is huge. The main fishing systems for saury are fish suction pumps and fish sorting systems. At present, the mechanical automation of most fishing boats is in a backward state, and many fishing boats are still in the manual fishing and fish sorting stage. Only a few large fishing boats use fish sorting machines, and their efficiency is incomparable to manual work.

[0003] Among all the existing sorting machines, tubular sorting is the main one. The scale of the sorting machines is relatively small, and there is still a lot of room for improvement in efficiency and sorting methods. Therefore, re-optimizing its working principle is of great significance to increase production, save costs and improve efficiency. Summary of the invention

[0004] The present invention mainly solves the technical problems existing in the prior art, thereby providing a shaft-rotating saury fish body primary sorting machine with high sorting efficiency and low labor cost.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions:

[0006] The shaft-rotating saury fish body primary sorting machine provided by the present invention comprises:

[0007] A sorter, comprising an inlet and an outlet connected to each other, wherein a plurality of partition plates are arranged at intervals on the outlet, and the outlet forms a plurality of sorting channels through the plurality of partition plates;

[0008] The upper box body has a plurality of groups of sorting units arranged inside, and there is a gap between two adjacent groups of sorting units, the gap gradually increases from right to left and corresponds to the position of the sorting channel, wherein the size of the gap at different positions along the length direction of the upper box body matches the size of the saury fish of different grades;

[0009] A gear box connected to the sorting unit and used to drive the sorting unit to rotate;

[0010] A plurality of front fish unloading boxes are arranged at intervals below the sorting unit;

[0011] The rear fish unloading box is arranged at the tail of the upper box body.

[0012] Furthermore, the sorting unit comprises two rollers arranged in parallel with each other, and the two rollers rotate in the same direction; and the two rollers close to each other in two adjacent groups of sorting units rotate in opposite directions.

[0013] Furthermore, the front fish unloading box and the rear fish unloading box are both arranged to be inclined downward, and the angles between the axes of the front fish unloading box and the rear fish unloading box and the horizontal plane are both 7°.

[0014] Furthermore, the gap between the two rollers of each group of the sorting units is 4 mm.

[0015] Furthermore, the roller is conical, with a maximum diameter and a minimum diameter of 24 mm and 16 mm respectively, and an inclination rate of the roller is 33%.

[0016] The beneficial effects of the present invention are as follows: after being diverted through the sorting channel of the sorter, the saury enters the sorting unit of the upper box body, and then, the gear box is used to drive the sorting unit to actively move and rotate, providing power requirements for the graded falling of the saury fish bodies. Then, after the saury fish bodies are driven by the rotation of the sorting unit, they fall into the corresponding front fish unloading box at the gaps at different positions to complete the sorting, and the sorting efficiency is high and the labor cost is low.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] See also Figure 1-5 As shown, the shaft-rotating saury fish body primary sorting machine of the present invention comprises:

[0025] The sorter 1 comprises an inlet 11 and an outlet 12 which are connected to each other, a plurality of partition plates 13 are arranged at intervals on the outlet 12, and the outlet 12 forms a plurality of sorting channels through the plurality of partition plates 13;

[0026] The upper box body 2 is provided with a plurality of groups of sorting units 3 inside, and there is a gap 4 between two adjacent groups of sorting units 3. The gap 4 gradually increases from right to left and corresponds to the position of the sorting channel. The sizes of the gaps at different positions along the length direction of the upper box body 2 match the sizes of the saury fish bodies of different grades.

[0027] The gear box 5 is connected to the sorting unit 3 and is used to drive the sorting unit 3 to rotate;

[0028] A plurality of front fish unloading boxes 6 are arranged at intervals below the sorting unit 3;

[0029] The rear fish unloading box 7 is arranged at the tail of the upper box body 2. In the present embodiment, the functions of the plurality of front fish unloading boxes 6 and the rear fish unloading boxes 7 are to transfer and collect the saury of different sizes after sorting, and transport them to different collection equipments.

[0030] In the present invention, the saury enters the sorting unit 3 of the upper box body 2 after being diverted through the sorting channel of the sorting device 1, and then the gear box 5 is used to drive the sorting unit 3 to actively move and rotate, so as to provide power requirements for the graded falling of the saury fish body. Then, after the saury fish body is driven by the rotation of the sorting unit 3, it falls into the corresponding front fish unloading box 6 at the gaps 4 at different positions to complete the sorting, and the sorting efficiency is high and the labor cost is low.

[0031] Preferably, the sorting unit 3 comprises two rollers (30, 31) arranged in parallel with each other, the rollers (30, 31) rotate clockwise relative to the gear box 5 from top to bottom for odd-numbered rollers, and counterclockwise relative to the gear box 5 for even-numbered rollers; the gap between the rollers (30, 31) in the same group is very small to ensure that their rotation is not affected. Preferably, the gap between the two rollers (30, 31) of each group of sorting units 3 is 4 mm. In this embodiment, bearings can be installed at both ends of each roller (30, 31) to ensure that the rotation of each roller (30, 31) does not interfere with each other.

[0032] The two rollers (30, 31) close to each other of two adjacent groups of sorting units 3 rotate in opposite directions, so that the individual rollers (30, 31) of different groups can form a downward turning motion, thereby promoting the falling of the saury.

[0033] In the present invention, in order to facilitate fish unloading, the front fish unloading box 6 and the rear fish unloading box 7 are both arranged to be tilted downward, and the angles between the axes of the front fish unloading box 6 and the rear fish unloading box 7 and the horizontal plane are both 7°.

[0034] In this embodiment, the rollers (30, 31) are conical, with a maximum diameter and a minimum diameter of 24 mm and 16 mm respectively, and the inclination rate of the rollers (30, 31) is 33%.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
