Abstract

The invention relates to a main line paying-off device for abyssal fish long lines and belongs to the technical field of fishery equipment. The main line paying-off device for the abyssal fish long lines comprises a motor (1), a traction idler wheel (10) and a pressing wheel (8). The main line paying-off device is characterized by further comprising a pair of guide wheels (13); the pair of guide wheels (13) is arranged below the traction idler wheel (10) in parallel and is rigidly connected by a reinforced supporting column (13); the reinforced supporting column (13) is horizontal; a paying-off slide groove (14) is arranged at a line outlet end of the traction idler wheel (10); the cross section of the paying-off slide groove (14) is U-shaped and the side wall of the paying-off slide groove (14) is hinged with a movable stopping rod (14a); a guide line channel is formed between the movable stopping rod (14a) and the lower wall of the paying-off slide groove (14); a guide wheel (12) is provided with a V-shaped wheel groove. According to the main line paying-off device for the abyssal fish long lines, the line jumping trouble in the paying-off process is avoided; the transmission between the motor and the traction wheel adopts gear transmission so that the stability is high and the reliability is high.

Description

technical field

[0001] The invention relates to a main line setting-off device for longline fishing of deep-sea fish, and belongs to the technical field of fishery equipment. Background technique

[0002] see figure 1 , the fishing method of longline fishing is to release a main line of tens of kilometers from the boat in the sea, and there are branch lines and floats tied at a certain distance on it, and the buoyancy of the floats is used to suspend the bait on the branch line in water of a certain depth , to lure fish to take the bait, so as to achieve the purpose of fishing.

[0003] Longline fishing boats are generally equipped with a main line release device for releasing the main line to the sea.

[0004] The pay-off device generally adopts a motor to drive the traction roller, and the traction roller drives the guide wheel and the pressure roller to rotate to release the trunk line. The function of the pressure roller is to prevent slippage between the wire rope an...
