Description

This invention relates to the fishing industry.

Devices for sorting fish are known, comprising an orienting device driven in a reciprocating motion and a sorting grid made of a set of fan-shaped tubes. Sorting takes place with the aid of gage gaps, forming x between the pipes. For removal of sorted fractions, there are trays located at a distance much longer than the fish and in a plane intersecting with the plane of the sorting grid.

However, the orientation of fish headfirst after sorting is disturbed, and when sorting fish into two fractions (saury, smelt, sprat, etc.), small fish are not delivered on one side of the plant, and large on the opposite side, which is necessary for rational equipment placement. .

In order to provide oriented delivery of small and large fish for subsequent technological operations, the proposed device is equipped with an additional sorting grid, the gratings are located on opposite sides of the orienting device and have receiving in reciprocating motion under each gage slot

gutters with partition walls and diverting chutes for small and coarse fractions. The gutters have a slope in the direction of fish disposal and are installed relative to the pipe grids at a plant smaller than the length of the fish.

To dispense large and small fractions of fish from opposite sides, diverting chutes and knees are used to turn the fish through 180 °.

FIG. 1 given the proposed device, front view; in fig. 2 - top view; in fig. 3 is a section along A-A in FIG. one; in fig. 4 - receiving chute.

The device consists of a sorting device made of horizontally arranged parallel grooves 1, right and left sorting grids representing a set of fan-shaped flow tubes 2, and receiving grooves 3 under them. The number of receiving grooves is equal to the number of calibrating slots. The boxes are located along the slots at a distance from the pipes that are shorter than the length of the fish, since at this distance the orientation of the fish head-to-face remains. In the grooves 3 (see PPG. 4), after a certain distance along the length, partitions are arranged at an angle to the axis of the grooves, which divide the small box into two parts — channel 5 for small fish and channel 6 for large fish. The channel for large fish passes under the calibrated slot, and the channel for small fish under the pipe. The continuation of the channels are diverting chutes 7 for large fish and diverting chutes 8 for small fish. On the left side of the device, estrus 7 for large fish begins, which is a continuation of the channels of the receiving grooves of the left sorting grid along which the large fish moves, and on the right side - diverting chutes 8 for small fish, which are continued by the channels of the receiving channels of the right sorting grid on which small fish moves. The diverting chutes have a knee 9, due to which the fish is rotated through 180 °, and an inclined part 10. along which the fish are oriented with the head facing forward. Orienting device, right and left sorting grids, receiving grooves, diverting chutes for large fish and diverting chutes for small fish reciprocate in a horizontal plane along the fish movement using any known vibrator, for example a crank rod. The device works as follows. The fish is evenly loaded into the grooves 1 of the orienting device by means of an elevator or a swing conveyor. Depending on how the fish gets into the grooves 1, i.e., with the head or tail part, it orients the head forward to the right or left. In the groove, the fish turns parallel to the axis of oscillation, orients along the back and, under the action of vibration, moves its head forward through it and enters the calibrating slot formed between the tubes 2 of the sorting grid. As the gauge slit progresses, the fish is sorted by thickness and enters the receiving groove 3. Since the groove is set apart from the pipes at a distance shorter than the fish, the fish, falling into the calibrating slot, meets the plane of the receiving groove 3 and begins under the action of vibration, slide along this groove headfirst, completely moving to it. By dividing the partition 4, small fish is retracted into channel 5. Fish of larger size enters channel 6. Large fish from the left sorting grid with the help of knee 9, diverting leaks 7 for large fish is rotated 180 ° and diverted to the opposite end of the rip where it is connected with a stream of large fish from the right grid and comes in separate chutes for further processing. The removal of small fish from the right sorting grid is carried out similarly to the removal of large fish from the left grid, and the removal of small fish from the left sorting grid is carried out similarly to the removal of large fish from the right grid. The subject matter of the invention 1. A device for sorting fish, comprising an orienting device and a sorting grid formed by a set of fan-like diverging tubes, characterized in that, in order to provide oriented delivery of small and large fish for subsequent technological operations, it is equipped with additional sorting grid, the grids are located on opposite sides of the orienting device and have, under each gauge slot, atno reciprocating motion adoptive baffled trough and diverting chutes for fine and coarse fractions having a bias toward retraction fish, the chute mounted relative reschetok pipe at a distance less than the length of the fish. 2. A device according to claim 1, characterized in that in order to dispense large and small fractions of fish from opposite sides, diverting chutes have a track to turn the fish through 180 °.
