Description

[Detailed description of the invention] The purpose of this invention is to cut frozen fish into two stages: rough cutting and thin cutting.

Conventionally, when feeding frozen fish as feed for aquaculture fish, it was thawed and cut into appropriate pieces depending on the growth rate of the aquaculture fish. However, this method not only contaminates seawater due to thawing and causes pollution problems, but also has the drawback of losing freshness.

By the way, this invention eliminates these drawbacks, and attempts to efficiently cut frozen fish into appropriate sizes without thawing it and throw it as fresh bait. It is. The structure will be explained in detail with reference to the drawings. 1 is a driving roller, 2 is a driven roller, and 3 is an endless transfer belt, which is suspended between the rollers 1 and 2. Reference numeral 4 denotes a ratchet wheel, which is fixed to the shaft end of the driving roller 1. 5 is a pawl, and the ratchet wheel 4
engages and disengages in order to drive intermittently. Reference numeral 6 denotes lower teeth, which are attached to a stand and horizontally fixed close to the driving roller 1 in the longitudinal direction. Reference numeral 7 denotes an upper blade, which is located almost directly above the lower blade 6, and is configured so that both blades mesh with each other to perform cutting, and the upper blade is formed into a slightly arcuate blade. Reference numeral 8 is a continuous rod, the upper end of which is pivotally connected to the side surface of the upper blade 7, and the lower end of which is eccentrically pivotally connected to the crank disk 9. Reference numeral 10 denotes an interlocking rod, which is located between the interlocking rod 8 and the pawl 5, and is pivotally connected to both of them in an interlocking manner. 11 is the discharge port 12,1
Reference numeral 2' denotes a discharge path which serves as a passage for cut frozen fish, and is structured into two stages, upper and lower.In the case of one-stage cutting, operate the handle 15 to lift a part of the upper discharge channel 12 upward; In this case, the discharge passage 12 is lowered to form a series of passages. Reference numeral 13 denotes a saw, which is provided in the shape of a comb at the end edge of the discharge path 12, and is formed so that the circular saw 14 can be rotated between each saw. Reference numeral 16 denotes a guide, which has strip plates erected on the left and right sides, and the upper tooth attachment portion is loosely inserted between the plates for vertical movement. 17 is a machine frame, 18 is a switch box, 19 is a machine stand, 20 and 20' are pulleys,
An endless belt is wound around this, and the circular saw machine 14 is rotated by transmission from an arbitrary drive mechanism.

This idea is structured as above, so
Next, to explain its operation, as the linking rod 8 rises in conjunction with the rotational movement of the crank disk 9 transmitted by an arbitrary drive mechanism, the upper blade 7 is pulled upwards via the linking rod 10. The pawl 5 catches the teeth of the ratchet wheel 4 and causes intermittent rotational movement of the driving roller 1 within the range of the momentum of pulling it forward.

The frozen fish placed on the transfer belt 3 stretched between the driving roller 1 and the driven roller 2 moves forward toward the lower blade 6 by this intermittent movement.

Due to the rotation of the crank disk 9, the connecting rod 8 is pulled down together with the upper blade 7, and at the same time the pawl 5 is disengaged from the teeth of the ratchet gear 4, idling backward, and the frozen fish on the feed belt 3 is lowered within the range of intermittent movement. The upper blade 7 and lower blade 6 engage to perform rough cutting (cross cutting only) by the amount that extends forward from the blade 6, and the discharge path 1 is cut.
2 and then to the discharge path 12, where it is automatically transferred to the top of the sana 13 according to its inclination. Next, the rotating force of the circular saw 14 is used to cut the fish into evenly sized pieces (only vertically), and the cut frozen fish falls from between the circular saws 14 onto the lower discharge passage 12'. It is discharged outside the machine from the discharge port. This operation is repeated, and the frozen fish that has been cut into pieces is fed directly as feed to farmed fish.

In this case, whether to cut in one step or into two steps can be performed arbitrarily depending on whether the upper discharge passage 12 is raised or lowered by operating the handle 15 and discharged from the discharge port.

As described above, this invention uses the intermittent movement of the transfer belt and the cutting teeth to roughly cut frozen fish, and then uses the rotational force of the circular saw to cut it into even pieces to make it easier to eat as feed for farmed fish. Since it is configured so that it can be cut to size and fed, there is no need for thawing as in conventional methods, and it is possible to efficiently feed farmed fish with fresh, high-nutrient content as it is, and it is easy to operate. If so, there may be practical benefits to solving the pollution problem.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. An endless transfer belt 3 is wound around a driving roller 1 and a driven roller 2 which are mounted on both left and right ends, and a ratchet is formed so that a pawl 5 can be engaged and released from the shaft end of the driving roller 1. A wheel 4 is provided, and the upper end of the connecting rod 8 is pivoted to the side surface of the upper blade 7 provided above so as to be able to engage with the lower blade 6 mounted horizontally close to the driving roller 1.
