In the prior art, a connecting flange is usually used as an intermediate connecting mechanism, and a large gear and a lower hook upper and lower cam are installed on both sides of the connecting flange, and the lower hook upper and lower cams are embedded in the outer side of the large gear, wherein the large gear and the lower hook upper and lower cams are integrally processed (such as Figure 5-6 ). In this way, the transmission mechanism drives the large gear to rotate, so that the upper and lower cams of the lower hook and the front and rear cams of the lower hook rotate accordingly to realize the action of lowering the hook. However, the front and rear cams of the lower hook are integrated with the large gear. After the front and rear cams of the lower hook are worn, it is inconvenient to replace them, and the replacement cost is high; and the processing procedures are high and the processing cost is high.

The front and rear waist grooves of the lower hook are arranged on the front and rear cams of the lower hook, and the front and rear screw holes of the lower hook are arranged on the large gear. The front and rear waist grooves of the lower hook and the front and rear screw holes of the lower hook correspond one to one, and the front and rear waist grooves of the lower hook and the front and rear screw holes of the lower hook are matched with front and rear bolts of the lower hook.
[0007] In this way, the front and rear waist grooves of the lower hook are aligned with the front and rear screw holes of the lower hook, and the front and rear bolts of the lower hook are tightened to fix the front and rear cams of the lower hook to one side of the large gear, which makes installation and disassembly more convenient.
[0008] As a further improvement of the utility model, the adjustable movable structure 2 includes a plurality of upper and lower waist grooves of the lower hook and upper and lower screw holes of the lower hook. The upper and lower waist grooves of the lower hook are arranged on the upper and lower cams of the lower hook, and the upper and lower screw holes of the lower hook are arranged on the large gear. The upper and lower waist grooves of the lower hook and the upper and lower screw holes of the lower hook correspond one to one, and the upper and lower waist grooves of the lower hook and the upper and lower screw holes of the lower hook are matched with upper and lower bolts of the lower hook.
[0009] In this way, the upper and lower waist grooves of the lower hook are aligned with the upper and lower screw holes of the lower hook, and the upper and lower bolts of the lower hook are tightened to fix the upper and lower cams of the lower hook to the other side of the large gear, which makes installation and disassembly more convenient.
[0010] As a further improvement of the utility model, the front and rear waist grooves of the lower hook are processed into arc shapes and are provided with seven of them, four of which are arranged in an arc shape near the outer periphery of the front and rear cams of the lower hook, and the remaining three are arranged in an arc shape near the middle of the front and rear cams of the lower hook.
[0011] In this way, since the center of gravity of the front and rear cams of the lower hook and the center of gravity of the large gear have a large deviation, the front and rear cams of the lower hook can be installed and fixed to the large gear more firmly through the cooperation of the seven waist grooves and screw holes, and the arc-shaped setting also makes it easier to rotate and adjust the angle of the front and rear cams of the lower hook on the large gear.
[0012] As a further improvement of the utility model, the upper and lower waist grooves of the lower hook are processed into arc shapes and are provided with four of them, three of which are arranged in an arc shape near the outer periphery of the upper and lower cams of the lower hook, the remaining three are arranged in an arc shape near the middle of the front and rear cams of the lower hook, and the remaining one is arranged near the middle of the front and rear cams of the lower hook.
[0013] In this way, since the deviation between the center of gravity of the upper and lower cams of the lower hook and the center of gravity of the large gear is smaller, the upper and lower cams of the lower hook and the large gear can be installed and fixed more firmly through the cooperation of the four waist grooves and screw holes, and the arc setting also makes it easier to rotate and adjust the angle of the upper and lower cams of the lower hook on the large gear.

DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings:
[0022] like Figure 1-4 The split large gear of a fishing net machine shown in the figure includes a large gear, which is characterized in that one side of the large gear is connected to the front and rear cams of the lower hook through an adjustable movable structure 1, and the other side of the large gear is connected to the upper and lower cams of the lower hook through an adjustable movable structure 2.
[0023] The adjustable movable structure 1 includes a plurality of front and rear waist grooves of the lower hook and front and rear screw holes of the lower hook. The front and rear waist grooves of the lower hook are arranged on the front and rear cams of the lower hook, and the front and rear screw holes of the lower hook are arranged on the large gear. The front and rear waist grooves of the lower hook and the front and rear screw holes of the lower hook correspond to each other one by one, and the front and rear waist grooves of the lower hook and the front and rear screw holes of the lower hook are matched with the front and rear bolts of the lower hook.
[0024] The second adjustable movable structure includes a plurality of lower hook upper and lower waist grooves and lower hook upper and lower screw holes. The lower hook upper and lower waist grooves are arranged on the lower hook upper and lower cams, and the lower hook upper and lower screw holes are arranged on the large gear. The lower hook upper and lower waist grooves and the lower hook upper and lower screw holes correspond to each other one by one, and the lower hook upper and lower waist grooves and the lower hook upper and lower screw holes are matched with lower hook upper and lower bolts.
[0025] The front and rear waist grooves of the lower hook are processed into arc shapes and are provided with seven of them, four of which are arranged in an arc shape near the outer periphery of the front and rear cams of the lower hook, and the remaining three are arranged in an arc shape near the middle part of the front and rear cams of the lower hook.
[0026] The upper and lower waist grooves of the lower hook are processed into arc shapes and are provided with four of them, three of which are arranged in an arc shape near the outer periphery of the upper and lower cams of the lower hook, the other three are arranged in an arc shape near the middle of the front and rear cams of the lower hook, and the remaining one is arranged near the middle of the front and rear cams of the lower hook.
[0027] In the utility model, the large gear is used as the intermediate connecting piece, the front and rear waist grooves of the lower hook are aligned with the front and rear screw holes of the lower hook, and the front and rear bolts of the lower hook are tightened to fix the front and rear cams of the lower hook to one side of the large gear, and the upper and lower waist grooves of the lower hook are aligned with the upper and lower screw holes of the lower hook, and the upper and lower bolts of the lower hook are tightened to fix the upper and lower cams of the lower hook to the other side of the large gear.
[0028] Since the center of gravity of the front and rear cams of the lower hook has a large deviation from the center of gravity of the large gear, it is required to select the cooperation of seven waist grooves and screw holes to more firmly install and fix the front and rear cams of the lower hook and the large gear; and since the center of gravity of the upper and lower cams of the lower hook has a smaller deviation from the center of gravity of the large gear, the cooperation of four waist grooves and screw holes can make the upper and lower cams of the lower hook and the large gear more firmly installed and fixed.
[0029] Since the lower hook realizes its forward, backward, upward and downward movement by the cooperation of the lower hook front and rear cams and the lower hook upper and lower cams, it is generally selected to determine the angle of the lower hook upper and lower cams on the large gear. By rotating the lower hook upper and lower cams, while ensuring that the lower hook upper and lower waist grooves are assembled and matched with the corresponding lower hook upper and lower screw holes, after the angles of the lower hook upper and lower cams are adjusted, the lower hook upper and lower bolts are screwed to assemble and fix the lower hook upper and lower cams and the large gear, and then the lower hook front and rear cams are assembled. Similarly, rotate the lower hook front and rear cams to ensure that the lower hook front and rear waist grooves are assembled and matched with the corresponding lower hook front and rear screw holes. After the angles of the lower hook front and rear cams are adjusted, the lower hook front and rear bolts are screwed to assemble and fix the lower hook front and rear cams and the large gear.
[0030] After working for a long time, the front and rear cams of the lower hook and the upper and lower cams of the lower hook will wear out. At this time, you only need to unscrew the corresponding bolts to remove the front and rear cams of the lower hook or the upper and lower cams of the lower hook, and then replace them with new ones and use them again. The replacement is more convenient, and the cams are separate individuals, so the processing is also more convenient and simple.
[0031] In the utility model, the front and rear cams of the lower hook and the upper and lower cams of the lower hook are fixedly connected with the large gear by bolts. No matter which one is worn out, it can be quickly disassembled and replaced, and each can be processed separately, so that the processing procedure is simpler and the processing cost is reduced.
[0032] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed herein, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
