It is connected between upper end by spring 1, the lower end of clamping limb 25 is hingedly connected with clamping jaw 27, and clamping jaw 27 and clamping limb 25 are cut with scissors
Place is met to connect by wind spring, since clamping jaw 27 is connect with the hinged place of clamping limb 25 by wind spring, two clamping jaws 27
It can be freely adjusted clamping force encountering different size of bivalves, to improve use scope.
In the present embodiment, the locking mechanism 19 that pin rod 22 is separated or connected with groove 20 is provided on crane 12, and
The block 11 that can be unlocked to locking mechanism 19 is fixed on hanger 5.
In the present embodiment, locking mechanism 19 includes the lever 28 being hingedly connected on crane 12, and lever 28 is in Z-shaped
Shape, and one end of lever 28 offers strip groove 29, and the effect of strip groove 29 is to release lever 28 to pin rod 22 in rotation side
To restraining force, so that it is guaranteed that pin rod 22 can move linearly under the action of guide sleeve 23, pin rod 22 far from rotating cylinder 15 one
End is slidably connected with strip groove 29, and 28 other end of lever can be contradicted with the block 11 being fixed on hanger 5 and be connected, and the end and liter
Frame 12 is dropped to connect by spring 2 30.
The present invention also provides a kind of application methods of fishing gear for fresh water bivalves, and operation is as follows when in use,
The following steps are included:
Step 1: such as Fig. 1, elevating lever 3 is controlled by control switch corresponding on dredger 1 and transfers hanger 5 to underwater
To appropriate depth, same moving down with hanger 5, crane 12 also synchronizes and is displaced downwardly to suitable position in water with hanger 5, first
Beginning state lower link 1 and connecting rod 29 are horizontal horizontal, and two clamping limbs 25 in clamping device 17 are in open configuration at this time,
With the movement of dredger 1, clamping device 17 is also being moved synchronously, when waterproof high-definition camera 18 shoots with video-corder bivalves, fishing
Personnel control the work rotation of motor 2 13 by control switch corresponding on dredger 1, and the rotation of motor 2 13 passes through polygon rod
14 drive rotating cylinders 15 rotate, rotating cylinder 15 rotation while groove 20 and pin rod 22 generation power effect so that rotating cylinder 15 is rotating
While moved down along polygon rod 14, i.e., generate active force between the screw inclined plane of groove 20 and pin rod 22, the active force by
The rotation of rotating cylinder 15 is applied on pin rod 22, and according to Newton's third law, pin rod 22 applies reaction force to rotating cylinder 15, so that turning
Cylinder 15 moves downward rotating cylinder 15 with downward movement tendency, and under the guiding role of groove 20 while rotation,
Moving down for rotating cylinder 15 drives change 21 to synchronize and move down, and change 21 is moved down through two connecting rods 3 24 respectively to described in two
The effect of 25 applied force of clamping limb, so that the upper end of two clamping limbs 25 is located remotely from each other, and can according to lever principle
Know, the lower end of two clamping limbs 25 is close to each other, and then drives that two clamping jaws 27 are close to each other clamps bivalves, so
It controls motor 2 13 by control switch corresponding on dredger 1 afterwards to stop working, at this time since pin rod 22 still connects with groove 20
It connects, therefore pin rod 22 applies position-limiting action, the anti-work for avoiding rotating cylinder 15 from being applied by spring 1 to rotating cylinder 15 by groove 20
It firmly moves up and clamping device 17 is caused to unclamp bivalves, improve the stability of clamping, it is right in two clamping limbs 25
The upper end of two clamping limbs 25 is located remotely from each other while bivalves clamps, while spring 1 is elongated, and make spring
One 26 obtain a restoring force；
Since clamping jaw 27 is connect with the hinged place of clamping limb 25 by wind spring, two clamping jaws 27 are encountering difference
The bivalves of size can freely be adjusted clamping force, to improve use scope, avoid the rigidity of clamping limb 25 larger to bivalves
Damage, and the bivalves of different size can be clamped；
Step 2: after clamping device 17 clamps bivalves, motor is controlled by control switch corresponding on dredger 1
2 13 stop working, and control motor 1 by control switch corresponding on dredger 1 and work, and motor 1 drives snail after being powered
Bar 4 rotates, and the rotation of worm screw 4 drives turbine 8 to rotate, and the rotation synchronous drive connecting rod 1 of turbine 8 is rotated around the center of turbine 8,
Such as Fig. 1 and Fig. 2, according to the motion trail analysis crane 12 of parallelogram mechanism while rising and to hanger 5
Close, until clamping device 17 is located at the top of storage box 10, block 11 contradicts with locking mechanism 19 connect simultaneously at this time, simultaneously
Corresponding control switch control motor 1 stops working on dredger 1, such as Fig. 4 and Fig. 6, contradicts in block 11 and arrives locking mechanism
When lever 28 in 19, apply the power for being directed toward crane 12 to lever 28, to compress to spring 2 30, so that spring two
30 obtain a restoring force, and the lever 28 while compression of spring 2 30 is rotated around the junction of lever 28 and crane 12,
So that pin rod 22 is far from rotating cylinder 15, until the groove 20 on pin rod 22 and rotating cylinder 15 is detached from, pin rod 22 and rotating cylinder 15 at this time
The effect for not generating power, under the restoring force effect of spring 1, the upper end of two clamping limbs 25 is close to each other, and passes through
3 24 pairs of changes 21 of connecting rod apply upward power, so that rotating cylinder 15 moves up reset along polygon rod 14, and can according to lever principle
Know, the lower end of two clamping limbs 25 is located remotely from each other while the upper end of two clamping limbs 25 is close to each other, i.e., and two
A clamping jaw 27 is located remotely from each other, and to the relaxation of the bivalves of clamping, bivalves is fallen in storage box 10, due in clamping device 17 by bivalves
Storage is moved to during 10, clamping jaw 27 remains the clamping to bivalves, bivalves will not be made to fall off, caught to improve
Efficiency is fished out, the amount of labour is reduced；
After bivalves is fallen in storage box 10, motor 1 is controlled by control switch corresponding on dredger 1 and is reversely turned
Dynamic, the reversion of motor 1 drives worm screw 4 to rotate backward, so that turbine 8 be driven to rotate backward, and then drives connecting rod 1 around turbine
8 center reversely rotates, similarly according to the motion trail analysis crane 12 of parallelogram mechanism in the same of decline
Shi Bingxiang hanger 5 is separate, until connecting rod 1 is in horizontal horizontal, while clamping device 17 resets, at this time block 11 and locking machine
Structure 19 separates, while corresponding control switch control motor 1 stops working on dredger 1, in block 11 and locking mechanism 19
In lever 28 separate after, spring 2 30 restoring force effect under, lever 28 is anti-around lever 28 and the junction of crane 12
To rotation, so that pin rod 22 is close to the rotating cylinder 15 after reset, and is slidably connected with groove 20, to carry out freshwater mussel next time
The fishing of class, entire process of catching is simple and convenient and time saving and energy saving, can be improved catching rate for fishing personnel
And safety；
Step 3: after storage box 10 fills bivalves, elevating lever 3 is controlled by control switch corresponding on dredger 1 and is driven
Hanger 5 moves up, while storage box 10 being made to expose the surface and the bivalves inside storage box 10 is emptied on dredger 1, then
Hanger 5 is driven to be displaced downwardly to the following suitable position of the water surface again by control switch corresponding on dredger 1 control elevating lever 3.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
For staff it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification is only this
The preference of invention, is not intended to limit the invention, and without departing from the spirit and scope of the present invention, the present invention also has
