Problems solved by technology

For the net lifting machine of this structure, since it is impossible to maintain equal strength when the person pulls the rope by hand, when the strength is insufficient, the contact between the rope and the surface of the working wheel will be poor, which will easily cause slipping and idling of the working wheel. Wear and loss of work efficiency
When the fishing net is damaged and crossed, it is easy to rewind and cause a safety accident
The net lifting machine of this structure is laborious and time-consuming, and is also prone to accidents
[0003] At present, there is also a pinch wheel mechanism to press the steel rope of the fishing net on the working wheel, but when the net is closed, when the line rope has other sundries, it is easy to damage the pinch wheel mechanism
In addition, the pressure produced by the existing pinch wheel mechanism is relatively large, which easily deforms the line rope and accelerates the wear and tear of the line rope, shortening the service life of the fishing net

Embodiment Construction

[0022] Such as figure 2 , image 3 , Figure 4 Shown, the present invention comprises frame 1, traction wheel 3, positioning wheel 4,5 and pressure wheel mechanism, and frame 1 side installs traction wheel 3, and traction wheel 3 is driven to rotate by the power unit installed in frame 1, A positioning wheel 4,5 is respectively set on both sides below the traction wheel, and the pinch wheel 6 on the pinch wheel mechanism is pressed on the traction wheel 3 . During work, the key line 15 of described fishing net walks around from one positioning wheel 4 to the traction wheel 3 top and then passes through another positioning wheel 5 below, and the pinch wheel 6 is pressed on the key line. Because the effect of pinch roller 6 makes key line 15 stick on the upper circumferential surface of traction wheel 3, key line 15 and traction wheel 3 contact area are big and produce enough frictional force, the phenomenon of traction wheel 3 idling and skidding can not take place. No need...

Abstract

The invention discloses a net hauling machine. The net hauling machine comprises a machine frame, a traction wheel, positioning wheels and a wheel pressing mechanism, wherein one side of the machine frame is provided with the traction wheel; the traction wheel is driven to rotate by a power device arranged in the machine frame; both sides of the lower side of the traction wheel are provided with one positioning wheel respectively; and a pressing wheel on the wheel pressing mechanism is pressed on the traction wheel. The pressing wheel is pressed on a wire rope to keep close to the upper peripheral surface of the traction wheel, and the large contact area of the wire rope and the traction wheel can generate enough great frictional force, so that the traction wheel cannot be idle. The wire rope can be automatically pulled up by the traction wheel without being pulled up by hands, so that the net hauling machine saves manpower and effectively reduces the wastage of the wire rope.

Description

(1) Technical field: [0001] The invention relates to a fishing machine, in particular to an automatic net lifting machine installed on a gillnet fishing boat. (two) background technology: [0002] For the convenience of sea fishing operations, many fishing boats are equipped with net lifting machines. Such as figure 1 As shown, the existing net lifting machine is composed of two parts, the machine base A and the machine head. The machine head includes a shell B, a motor C installed in the shell B, and four working wheels D installed outside the shell B. The four The working wheels D are distributed in a rectangular shape. The output shaft of the motor C is connected to the rotating shaft of the working wheels D through gears. Driven by the motor C, the four working wheels D rotate simultaneously, and the main rope E of the fishing net bypasses the four working wheels D respectively. During use, one person needs to tighten the line rope E at one end, so that the line rope E...
