Description

[Detailed explanation of the invention] (Field of industrial application) The invention is used in aquaculture fisheries to provide feed to farmed fish.
The present invention relates to a bait casting device mainly used for feeding cut fish bait.

(Prior Art) Feeds given to farmed fish include whole baits fed whole fish, cut baits made by cutting the fish bodies into appropriate sizes, artificially prepared baits called pellets, minced baits, and the like.

Conventionally, when feeding cut bait, the fish bodies of frozen or live fish used as bait are manually cut, collected, and transported to a separately installed bait casting machine.
This feeding machine was used to release the fish into the cage.

(Problem to be solved by the invention) However, in the conventional method described above, not only is the workability very poor as it takes time and effort to cut the fish body and transfer the cut bait, but it is also difficult to cut the fish by hand. There was a problem with variations in the size of the bait.

The present invention was developed by focusing on these conventional problems, and it is possible to continuously cut the bait and release the cut bait with one device, and also to make the size of the cut bait uniform. The challenge is to make this possible.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes a supply-side screw feeder that receives and transfers the feed, and a feeder that receives and cuts the feed from the supply-side screw feeder. A cutter unit, a discharge screw feeder that receives and transfers the cut bait cut by the cutter unit, and an air thrower that receives the cut bait from the discharge screw feeder into a bait chute and releases it with air. Consists of a bait machine,
The feeding screw feeder is configured to adjust the helical angle of the alignment screw blade at the tip end to the feeding screw blade at the base end so that the longitudinal direction of the feed to be transferred is oriented in the axial direction of the feeding screw feeder. The cutter unit is formed to be larger than the helical angle, and the cutter unit includes a fixed comb blade, which is disposed on the side of the tip of the supply screw feeder, and whose blade direction is orthogonal to the axial direction of the supply screw feeder; A configuration is adopted in which rotating blades are arranged in parallel on a rotating shaft so as to fit into the gap between fixed comb blades.

(Function) When round bait as bait is put into the supply screw feeder, the bait is transferred to the tip of the supply screw feeder, where the alignment screw blades align the bait in the longitudinal direction. is oriented in the axial direction of the screw feeder on the supply side, so the fixed comb blade whose blade direction is perpendicular to the axial direction of the screw feeder on the supply side and the rotary blade are used to feed the feed from the lateral direction with respect to the longitudinal direction. disconnected.

The cut bait cut by the cutter unit in this manner is transferred to the bait chute of the air bait throwing machine by the discharge side screw feeder, and discharged from the bait chute on the air jet.

Therefore, cutting of the bait and discharging of the cut bait can be performed continuously by one device.

Further, the screw shaft 20 has a feeding screw blade 23 provided on the base end side and having a small helical angle.
and two alignment screw blades 24 and 25 provided on the tip side and having a large helical angle.

The alignment screw blades 24 and 25 are used to feed the feed transferred by the feeding screw blade 23.
This is for aligning the screw blades so that their longitudinal direction faces the axial direction of the screw shaft 20, and both alignment screw blades 24 and 25 have a phase of 180°,
The helical angle is approximately 1/4 pitch with respect to the entire length of the cutter unit 3, and one alignment screw blade 24 is continuous with the feed screw blade 23, and the other alignment screw blade 25 is connected to the feed screw blade 23. It is separated from the blade 23.

The cutter unit 3 is for receiving and cutting the feed from the feed screw feeder 2, and is disposed on the side of the tip of the feed screw feeder 2, and the blade direction is the same as that of the feed screw feeder 2. A fixed comb blade 30 that is orthogonal to the axial direction of the feeder 2, and a rotary blade 3 that is arranged in parallel on a rotating shaft 31 with a constant gap maintained so as to fit into the blade gap of the fixed comb blade 30.
2, and a scraper 33 fixed to the inner surface of the cover 13 of the casing 1 is provided so as to fit between the respective rotary blades 32, 32.

In addition, the blade unit 3 is entirely removable in order to cope with cases where cutting of bait is not required. In this case, either the fixed comb blade 30 or the rotary blade 32 that constitute the blade unit 3 can be removed It may be made removable.

The discharge side screw feeder 4 is for receiving and transferring the cut bait cut by the cutter unit 3, and is provided behind the cutter unit 3, and its tip end is used to receive and transfer the cut bait cut by the cutter unit 3. It extends above the chute 50.

The base end of the screw shaft 40 of the discharge side screw feeder 4 and one end of the rotary shaft 31 of the rotary blade 32 each extend into the drive box 12 and are connected to a drive motor 61 via a power transmission mechanism 60. ing.

The air bait chute 5 has a tubular bait chute 50 with an air inlet 51 at one end and an air bait port 52 at the other end.

This air bait casting machine 5 uses a blower to forcefully blow air from an air inlet 51, and releases cut bait from an air bait casting port 52 on the air jet produced by the forced air. As the speed increases, negative pressure is generated, and the cut bait from the discharge side screw feeder 4 is sucked by this negative pressure, so that the cut bait can be received smoothly.

Next, the cutting action of the cutter unit 3 will be explained.

Since alignment screw blades 24 and 25 with a large helical angle are provided at the tip of the supply side screw feeder 2, the feeding screw blade 23
The round baits F transferred are aligned at this tip so that their longitudinal direction faces in the same direction as the axial direction of the screw shaft 20, and are sent out to the cutter unit 3 in this state. Since the blade direction of the cutter unit 3 is perpendicular to the axial direction of the screw feeder 2 on the supply side, the round bait F is shredded in the gap between the rotary blades 32 in parallel to the longitudinal direction. That will happen. Incidentally, the cutting bait, chips, etc. adhering to the side surface of the rotary blade 32 are scraped off by the scraper 33.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to the above embodiments.
