Description

  The present invention is a fish fastening mechanism for a fish clamp, which is devised so that fish caught mainly by fishermen, anglers, etc. or fresh fish cookers can be easily tightened from raw fish etc. It is about.

  Conventionally, when tightening captured fish, tools such as knives, knives, or perforations are used, and when tightening fish, the tips of these blades are inserted between the raw fish's elasto and the spinal nerves of the raw fish. As well as cutting the blood, the freshness of the captured fish is kept.

  However, according to the above-mentioned method, a considerable amount of experience and skill is required to fasten a large amount of raw fish quickly, and with the aging of fishermen and other fishermen engaged in such fishery, There is a current situation where such work is becoming difficult.

Problems to be solved by the invention

  Therefore, the present invention solves the above-mentioned problems, and can save a large amount of raw fish in a short time without requiring much experience and skill, yet is easy to operate and energy efficient. It creates a robust fish tightening mechanism for fish clamps that is good and can withstand use even at relatively rough handling sites.

Means for solving the problem

  In order to solve the above-mentioned object, in the fish tightening mechanism according to claim 1 of the present invention, a high torque rotation is obtained by combining a rechargeable battery and a small high power motor, and the rotation is performed accordingly. It is equipped with a rotation-linear conversion mechanism that moves the cutting blade back and forth for tightening.

  The rotation-linear conversion mechanism employs a pendulum type inertial rotation continuation mechanism for maintaining the rotational force of a driving source such as a motor, and the rotation-linear conversion mechanism uses a cutting blade to rotate the drive shaft. In order to convert to reciprocating motion, a crank mechanism was adopted.

  A series of functions on the mechanism will be described with reference to FIG. 1. A bevel gear 3 is attached as a drive gear to the drive shaft 1 of a motor or the like, and a bevel gear as a follower gear is attached to the driven shaft 2. A gear 4 is attached. These gears are fixed to the respective shafts by means such as press fitting, and are rotated integrally with the rotation of the respective shafts.

  Then, when the drive shaft 1 is rotated, the driven gear 4 is rotated by the drive-side bevel gear 3 so that the drive shaft 1 and the driven shaft 2 are rotated orthogonally.

  And it is comprised as a crank, The pin 6 which is implanted in the arbitrary positions on the rotation circumference of the rotary disk of the rotary disk 5 with the axis | shaft fixed as a component at right angles with respect to the rotary disk. In the pin, a bearing 7 that can rotate about the pin is inserted. The rotation center of the pendulum 8 and the pendulum that are attached to the pin by press-fitting the bearing is made to coincide with the rotation center of the driven shaft 2.

  Since the crank mechanism is configured in this way, the rotation of the drive shaft is converted into the orthogonal rotation of the driven shaft, and the bearing inserted into the pin on the rotating disk is rotated at an arbitrary turning radius around the driven shaft. I was able to rotate.

  A crank mechanism configured to give a linear motion to the cutting blade is attached with a link 9 to a pin 6, and the link is provided with a long hole for fitting into a bearing 7 inserted into the pin of the rotating disk 5. The link can keep up with the swinging movement of the crank in a circumferential motion, and the mechanism is simplified.

  In addition, a semicircular groove is provided on the outer edge of the link 9 in the straight direction, and a guide pin 10 is attached to the groove so as to contact the radial surface of the semicircular groove of the link, thereby stabilizing the linear motion of the link. In addition, rotation was not generated in the linear motion of the link.

  In this way, the rotation of the drive shaft is converted in the rotation direction by the drive gear and the driven gear, and the crank movement of the pin of the rotating disk accompanying the rotation of the driven shaft, the long hole of the link inserted and joined to the pin bearing This changes the crankshaft motion of the pin and bearing to the linear motion of the link.

  In addition, the pendulum 8 provided coaxially with the driven shaft 2 prevents uneven crank motion, smoothes a series of rotation to linear operation, and enables stable supply of battery current of a motor, etc. In addition to the effect of prolonging, the pendulum type inertial rotation continuation mechanism is adopted.

  Then, by setting the threaded portion and the protruding portion so that an arbitrary cutting blade 11 (for example, a knife blade or a saw blade) can be attached to the tip of the link that performs linear motion, the cutting according to the target fish is performed. The blade can be easily replaced by one mounting screw 12.

  In the fish tightening mechanism according to claim 2, two sets of rotation-linear conversion mechanisms are used, and the two sets of rotation-linear conversion mechanisms are in a normal state in which the phases are shifted from each other by 180 degrees on the driven shaft. By setting it to operate, the two sets of rotation-linear conversion mechanisms and the linear motion of the cutting blade were alternately advanced and retracted to improve the fish tightening efficiency.

  Further, in the fish tightening mechanism according to the third aspect, the rotational motion of the drive shaft is not converted into linear motion, the rotation of the drive shaft is taken out as it is, and the rotary blade 13 (drill-like rotation is attached to the tip of the rotational shaft. A fixing mechanism 14 (three-way chuck or the like) that can be attached to and detached from the blade is provided, and an arbitrary rotary blade can be attached, and a method of cutting the spinal nerve of the raw fish with the rotary blade was adopted.

The invention's effect

  In the fish tightening mechanism according to claim 1, the conventional method has a large amount without experience and skill, and the live fish cannot be tightened for a long time. By adopting it as a container, even an inexperienced person can do the work with a little proficiency. In addition, even an old fisherman who is losing physical strength can perform the fish tightening work for a long time without fatigue.

  The electric fish tightening mechanism according to claim 2 can realize an effect that the number of fish tightening tails per unit time is approximately twice that of the fish tightener adopting the fish tightening mechanism according to claim 1, and alternate between the two blades. It has the effect of suppressing the vibration of the device by the reciprocating operation and enabling a smoother mechanism operation.

  The fish tightening device employing the fish tightening mechanism according to claim 3 can contribute to fish tightening and processing of seafood that cannot be solved by the conventional method, that is, reciprocal cutting with a knife-like blade. For example, it can be used for processing hard boned fish and armor.

  Referring to FIG. 4, the fish tightener employing the fish tightening mechanism of the present invention will be described. The main body case 15 for housing the fish tightening mechanism, the electrical / battery unit cover 16, the blade cover 17, the contents of the motor 18, the pendulum type It comprises a rotation-linear conversion mechanism including an inertial rotation continuation mechanism, a link 9, a blade attachment part, an electrical / battery part 19, and an on / off switch 20. Most functional components, including motors, can be handled as a single unit if they are built into the housing to make them easier to handle as a unit. This contributes to improved productivity and ease of handling in terms of management. improves.

  If the projection 9 that fits into the hole of the cutting blade and the screw (female screw) that fixes the cutting blade are provided at the tip of the link 9 to which the cutting blade is attached, it is easy to use one mounting screw 12 (male screw). The cutting blade can be attached and detached. Therefore, it goes without saying that different types of cutting blades can be handled by setting two holes as standard dimensions in the mounting portion of the cutting blade.

  In order to maintain the watertightness of the case inside and outside the case, the link mechanism that goes back and forth can enhance the waterproof effect by using an appropriate packing for the sliding portion.

  In order not to impair the fish tightening effect of the cutting blade, the semi-circular groove is provided at both ends of the outer edge of the link 9 in order to maintain the straight movement of the sliding link mechanism and maintain the mechanism operation without waste. Engaging the groove portion with the guide pin 10 provided on the main body so that the link slides along the guide pin can realize an efficient mechanism operation and contribute to the extension of the service life of the main body. .

The package containing the components should be watertight to protect the precision operating mechanism, motor 18, electrical / battery unit 19, etc. from moisture and moisture (mainly seawater). Therefore, the exterior package is configured as a structure using the packing 21 in the combination part so as to have waterproofness.

  FIG. 5 shows a basic package of the application example of FIG. 4. The package is composed of about three packages such as a main body 15, an electrical / battery unit cover 16, a blade cover 17, and the like. In the case of mass production using engineering plastics, the number of molds can be minimized, so that the cost of the molds can be saved and the efficiency of parts management is improved.

  In addition, by forming a portion corresponding to the handle of the package into an uneven or corrugated shape with good grip, it is possible to constitute a fish clamp for raw fish that can be used for long-time work.
