Description

Description: TECHNICAL FIELD The present invention relates to a fishing net lifting device for fishing boats, and more particularly to a fishing net lifting device for fishing boats that can reduce fatigue of an operator and can be installed in a narrow space. BACKGROUND ART Generally, a fishing net lifting device for a fishing boat is provided at or near the bow of a fishing boat so that an operator can easily raise the fishing net. As shown in FIG. 1, such a conventional fishing net lifting device for a fishing boat is provided with a roller 6, and a motor 1 is connected to the central axis of the roller 6. The motor 1 and the roller 6 can be directly connected, or the central axis of the roller 6 and the drive shaft 2 of the motor 1 can be connected via a belt 3 or a chain. In such a conventional fishing net lifting device for a fishing boat, when a motor (1) is driven by turning on a switch (not shown), the roller 6 is driven by the drive shaft 2 and the belt 3 in the direction of the arrow in FIG. It becomes easy to pull up the fishing net 5 on the fishing boat 10 by rotating to. By the way, in such a conventional fishing net lifting device for fishing boats, as shown in FIG. 2, the contact area between the roller 6 and the fishing net 5 is not so large, so that the rotational force of the roller 6 is transmitted to the fishing net 5 at all. The fishing net 5 cannot be rolled up on the fishing boat 10 and a slip occurs between the two, so that the fishing net is lifted by the operator's manpower. Therefore, the original purpose of the fishing net lifting device is achieved. In the end, there was a problem of weighting the worker's fatigue. Therefore, conventionally, as shown in FIG.
Development and use of fishing net lifting equipment for fishing boats. This includes a first roller 16 and a second roller 18 and an auxiliary roller 17 provided between the two rollers. A motor (not shown) is connected to the first roller 16, and a chain 13 is interposed between the first roller 16 and the second roller 18.
Or connected with a belt. In such a conventional fishing net lifting device for fishing boats, the fishing net 15 comes into great contact with the outer peripheral surfaces of the three rollers 16, 17, 18 as compared with the lifting device shown in FIG. The rotational force is surely transmitted to the fishing net 15 and the fishing net 15 is easily lifted onto the fishing boat 10. By the way, in such a conventional fishing net lifting device for fishing boats, the three rollers 16, 17, 18 must be installed at a predetermined interval, and the transmission of a chain 13 or a belt is carried out between these rollers. Since the means must be further provided, a relatively wide installation space is required, which causes a problem that the working space is reduced and the installation cost is increased. DISCLOSURE OF THE INVENTION An object of the present invention for solving the above-mentioned problems is to provide a fishing net lifting device for a fishing boat which can reliably lift a fishing net on a fishing boat and can be installed in a narrow space. It is to provide. In order to achieve the above object, a fishing net lifting device for a fishing boat according to the present invention comprises a roller provided at or near the bow of a fishing boat and a motor for rotating the roller, and facilitates the fishing net. In a fishing net lifting device for a fishing boat, the roller includes a first roller and a second roller that are connected to the drive shaft of the motor and continuously provided on the same axis, and has a diameter larger than the diameter of the roller. A separating plate provided between the first roller and the second roller, an auxiliary roller provided on one side of the circumference of the separating plate, and guiding a fishing net wound around the second roller through the first roller; It is characterized by comprising. Accordingly, the pulling device according to the present invention comprises:
Can be installed in a small space that is not too big,
The fishing net is wound around the first roller, the auxiliary roller and the second roller in a zigzag manner to increase the contact area, and the fishing net is certainly lifted by the rotational force of the roller, so that the work space can be utilized to the maximum extent, There are effects such as reducing the fatigue of workers. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific features and advantages of the present invention will be described more clearly with reference to the accompanying drawings. As shown in FIG. 4, the fishing net lifting device for a fishing boat according to the present invention is roughly divided into a motor 21 and a roller 26. A drive shaft 22 is connected to the motor 21, and this drive shaft is connected to the central axis of the roller 26.
A guide 23 supports the intermediate portion of the. On the other hand, the roller 26 has a shape in which a first roller 27 and a second roller 28 are integrally formed, and a coupling groove 2 is formed between the first roller 27 and the second roller 28.
9 is provided. A circular diaphragm 30 having a relatively large diameter is coupled to the coupling groove 29 of the roller 26. One side of the partition plate 30 is fixedly supported by a bracket so that it does not rotate with the roller 26 when the motor 21 is driven. An incision groove 31 is formed on one side of the periphery of the partition plate 30.
The auxiliary roller 3 is formed on both sides of the incision groove 31.
2 are combined. In the fishing net lifting apparatus for fishing boats according to the present invention having such a structure, one end of the fishing net 25 is hooked on the outer peripheral surface of the first roller 27, and is passed through the outer peripheral surface of the auxiliary roller 32 to the outer peripheral surface of the second roller 28. Position on top of. In this state, when the motor 21 is driven to pull up the fishing net 25, the roller 26 is rotated by the drive shaft 22. The operator slightly pulls the end of the fishing net 25 on the fishing boat 20 so that the fishing net 25 comes into close contact with the first roller 27, the auxiliary roller 32, and the second roller 28. Here, the contact state between the roller 26 and the fishing net 25 wound around the roller 26 is examined as follows. When the fishing net 25 passes through the auxiliary roller 32 through the outer peripheral surface of the first roller 27, it contacts the outer peripheral surface of the first roller 27 by about 180 ° as shown in FIG.
In addition, since the fishing net 25 is contacted and supported in a tightly pulled state, no slip occurs between the first roller 27 and the fishing net 25. In addition, the fishing net 2 via the first roller 27
When 5 is wound around the second roller 28 through the auxiliary roller 32, the fishing net 25 is contacted and supported by about 180 ° on the outer peripheral surface of the auxiliary roller 32, and is drawn onto the fishing boat 20 after passing through the second roller 28, The second roller 28 is also in close contact with and brought into contact with the second roller 28 by about 180 °. Accordingly, the fishing net 25 has the first roller 27.
Half rotation, auxiliary roller 32 half rotation, second roller 2
8 is wound in half a turn, and is not wound in the same direction, but is wound in a zigzag manner, so that the contact area is maximized and the fishing net is pulled, so that the outer peripheral surface of the roller and the fishing net 25 The contact surface is more closely attached. Therefore, when the motor 21 operates and the roller 26 rotates, even if the end of the fishing net 25 is pulled slightly, the fishing net 25 is pulled up by the rotational force of the roller 26, and the operator raises the fishing net 25. Since it is only necessary to organize and store the work, the work becomes easier and the fatigue of the operator is considerably reduced. Such a fishing net lifting device for a fishing boat according to the present invention can be installed in a narrow space because the roller 26 around which the fishing net 25 is wound is not so large, and this has the effect of widening the work space. is there. As described above, according to the fishing net lifting device for a fishing boat according to the present invention, the lifting device is not so large and can be installed in a narrow space.
The auxiliary roller 32 and the second roller 28 are pulled up by the rotational force of the roller while being wound in contact with a wide surface in a zigzag manner, so that the working space can be utilized to the maximum and the operator's fatigue is reduced. There are effects such as obtaining. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a conventional fishing net pulling device for fishing boats.
