Step five: the front end of the culture rope enters a mussel separation tube, and the mussel separation tube separates inner mussels on the culture rope;
step six: the separated mussels are discharged from the through groove.
Compared with the prior art, the device has the following advantages:
1. In the mussel picking process of the device from the culture rope, the culture rope is firstly placed on a mussel slideway of an operation table through a crane, and then the end part of a cable penetrates through a mussel separating tube and is connected to the front end of the culture rope. The drive mechanism and the strander are then simultaneously activated. The driving mechanism drives the round table-shaped shell to rotate, and the cable winch pulls the culture rope through the cable, so that the front end of the culture rope enters the round table-shaped shell and advances towards the mussel separating tube. Mussels gradually enter the round table-shaped shell under the drive of the culture rope, and at the moment, the outer mussels on the culture rope are contacted with the inner wall of the round table-shaped shell and are extruded, so that the outer mussels are subjected to acting force opposite to the movement direction of the culture rope; when the round table-shaped shell rotates, the outer mussels are driven to deflect relative to the culture ropes, so that the outer mussels are subjected to torque action in the circumferential direction. The mussels on the outer side are separated from the culture rope under the action of acting force and torque given by the circular table-shaped shell, so that the number of the mussels is reduced. Because the outside mussel drops before being attached to the inside mussel, the outside mussel is transmitted to the inside mussel under the action of the acting force and the torque given by the round table-shaped shell, so that the closely connected inside mussel is loose, the adhesive force of the inside mussel attached to the culture rope is greatly reduced, and the gap between the mussels is increased. As the culture ropes move forwards into the mussel separating pipes, the root parts of the inner mussels are contacted with the end parts of the mussel separating pipes and are extruded; under the action of mussel separating pipe ends, the inner mussels are separated from the culture ropes. The separated mussels are discharged through the through groove. Above-mentioned in-process, because round platform shape casing makes the outside mussel receive round platform shape casing simultaneously and give effort and moment of torsion effect, this makes the outside mussel easily separate from breeding the rope, also makes the adhesion of inboard mussel adhesion on breeding the rope reduce greatly simultaneously to reduce the extrusion of mussel separator tube to the mussel, avoid the mussel damage. According to the structure, the outside mussels and the inside mussels are separated in sequence, so that the picking efficiency of the mussels is remarkably improved.
2. After mussels enter the round table-shaped shell, the outside mussels firstly contact and squeeze the movable strips. The movable bar drives the movable bar connecting rod to move outside the circular truncated cone-shaped shell and simultaneously compresses the first reset spring. The compressed first return spring enables the movable strip to have a movement trend of approaching to the axis of the round table-shaped shell. The mussel in the outside separates, drops from inboard mussel under round platform shape casing's effort and moment of torsion effect, also makes inboard mussel loose simultaneously, and the gap between the mussel increases, thereby this helps the activity strip to inject the mussel in the gap of mussel thereby further loosely breeds the mussel on the rope, helps improving the mussel picking efficiency of this device. When the mussel is separated from the culture rope and falls, the movable strip extrudes the falling mussel under the action of the first reset spring, so that the mussel is helped to be discharged out of the circular-table-shaped shell, and the mussel is accelerated to be discharged.
3. Mussels enter the circular table-shaped shell, the extrusion rod is extruded by the mussels and is retracted into the extrusion rod shell, and meanwhile the second reset spring is compressed. Under the action of the second reset spring, the extrusion rod extrudes mussels outside the round table-shaped shell, so that gaps between the mussels outside the round table-shaped shell and the mussels in the round table-shaped shell are increased, the torque action of the round table-shaped shell on the mussels is improved, and the mussel picking efficiency of the device is further improved. Simultaneously, the structure makes the cultivation rope both ends that are in the round platform shape casing receive the stretching, effectively improves the tensioning degree of this part cultivation rope, further improves the moment of torsion effect of round platform shape casing to the mussel.
4. After mussels enter the round table-shaped shell, the auxiliary separating knife is extruded by the mussels, so that the auxiliary separating rod is retracted into the auxiliary separating rod shell, and the third reset spring is compressed. Under the action of a third return spring, the auxiliary separating knife is inserted into the gap of the mussel. The mussels continuously move under the combined action of the torque action of the round table-shaped shell and the reaction force of the mussel separating tube, so that the auxiliary separating rod performs retracting and extending movements. The auxiliary separating knife moves up and down under the drive of the auxiliary separating rod, so that the mussel is subjected to acting force in the up-down direction by the auxiliary separating knife, and the mussel picking efficiency of the device is further improved.

Detailed Description
The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1 to 4, a mussel picking device comprises an operation table 1 for placing a culture rope 7, wherein the operation table 1 comprises a mussel slideway 11 and a culture rope recovery slideway 12 in the same direction, a baffle 22 is vertically and fixedly arranged at one end of the culture rope recovery slideway 12, a mussel separation tube 2 is fixedly arranged on the baffle 22, and the axis of the mussel separation tube 2 is parallel to the length direction of the culture rope recovery slideway; the operation table 1 is respectively provided with a cable winch 13, a cable 131 is wound on the cable winch 13, one end of the culture rope 7 passes through the mussel separating tube 2, and the end of the culture rope is detachably connected with the end of the cable 131; further comprises:
the round table-shaped shell 3 is coaxially arranged with the mussel separating tube 2, the small-diameter end part of the round table-shaped shell 3 is fixedly arranged on the rotating wheel 61, the rotating wheel 61 is coaxially arranged and rotationally connected with the mussel separating tube 2, and the large-diameter end part of the round table-shaped shell 3 is a free end; two through grooves 31 for discharging mussels are formed in the inner wall of the circular truncated cone-shaped shell 3; the operation table 1 is further provided with a driving mechanism capable of driving the rotating wheel 61 to rotate.
In the process of picking mussels from the culture rope 7, the culture rope 7 is firstly placed on the mussel slideway 11 of the operation table 1 through the crane, and then the end part of the cable 131 penetrates through the mussel separating tube 2 and is connected to the front end of the culture rope 7. The drive mechanism and the strander 13 are then activated simultaneously. The driving mechanism drives the round table-shaped shell 3 to rotate, and the cable twisting machine 13 pulls the culture rope 7 through the cable 131, so that the front end of the culture rope 7 enters the round table-shaped shell 3 and advances towards the mussel separating tube 2. Mussels are driven by the culture rope 7 to gradually enter the round table-shaped shell 3, and at the moment, the mussels on the outer side of the culture rope 7 are contacted with the inner wall of the round table-shaped shell 3 and are extruded, so that the mussels on the outer side are subjected to acting force in the opposite direction to the movement direction of the culture rope 7; when the round table-shaped shell 3 rotates, the outer mussels are driven to deflect relative to the culture ropes 7, so that the outer mussels are subjected to torque action in the circumferential direction. The outside mussels are separated from the culture rope 7 under the action of the acting force and the torque given by the round table-shaped shell 3, so that the number of the mussels is reduced. In addition, because the number of mussels on the culture rope 7 is large, the whole weight of the culture rope 7 is large, and the culture rope 7 is also under tension by the cable twisting machine 13, so that the torque action of the round table-shaped shell 3 on the outer mussels is insufficient to drive the culture rope 7 to twist, and the round table-shaped shell 3 effectively separates the outer mussels from the culture rope 7. Because the outside mussel drops before attaching on the inboard mussel, the outside mussel receives the effort and the moment of torsion effect that round platform shape casing 3 gave and transmits for the inboard mussel, makes closely continuous inboard mussel loose, reduces the adhesive force that the inboard mussel attached to on breeding rope 7 greatly, and the gap between the mussel increases. As the culture rope 7 moves forward into the mussel separating tube 2, the root of the inner mussel is contacted with the end of the mussel separating tube 2 and is extruded; under the action of the end part of the mussel separating tube 2, the inner mussels are separated from the culture ropes 7. The separated mussels are discharged through the through-groove 31.
Above-mentioned in-process, because round platform shape casing 3 makes the outside mussel receive round platform shape casing 3 simultaneously and give effort and moment of torsion effect, this makes the outside mussel easily separate from breeding rope 7, also makes the adhesive force that inboard mussel attached to on breeding rope 7 reduce greatly simultaneously to reduce mussel separator tube 2 to the extrusion of mussel, avoid the mussel damage. According to the structure, the outside mussels and the inside mussels are separated in sequence, so that the picking efficiency of the mussels is remarkably improved.
Specifically, six strip-shaped movable strips 32 are arranged in the round table-shaped shell 3 around the axis of the round table-shaped shell 3; the outer end of each movable strip 32 is hinged to the end part of the circular truncated cone-shaped shell 3 with the large diameter, and the inner end of each movable strip extends to the end part of the circular truncated cone-shaped shell 3 with the small diameter; each movable bar 32 is hinged with a movable bar connecting rod 33, the movable bar connecting rods 33 are inserted into positioning holes 331 formed in the inner wall of the circular truncated cone-shaped shell 3, and each movable bar connecting rod 33 is sleeved with a first reset spring 34; one end of the first return spring 34 is propped against the movable strip 32, and the other end is propped against the inner wall of the circular truncated cone-shaped shell 3; under the action of the first return spring 34, one end of the movable bar 32 is close to the axis of the truncated cone-shaped housing 3.
After the mussels enter the truncated cone-shaped shell 3, the outside mussels contact and press the movable strip 33. The movable bar 33 drives the movable bar connecting rod 33 to move outwards of the truncated cone-shaped shell 3, and simultaneously compresses the first reset spring 34. The compressed first return spring 34 causes the movable bar 33 to have a movement tendency toward the axis of the truncated cone-shaped housing 3. The mussel in the outside separates, drops from inboard mussel under round platform shape casing 3 effort and moment of torsion effect, also makes inboard mussel loose simultaneously, and the gap between the mussel increases, thereby helps the mussel on the movable strip 33 inner intubate further loose string 7 in the gap of mussel, helps improving the mussel picking efficiency of this device.
After the mussel is separated from the culture rope 7 and falls, the movable strip 33 extrudes the falling mussel under the action of the first reset spring 34, so that the mussel is helped to be discharged out of the round table-shaped shell 3, and the mussel is accelerated to be discharged.
Specifically, one end of the mussel separating tube 2 protrudes into the truncated cone-shaped housing 3 and a separating gap 21 is formed between the end and the inner wall of the truncated cone-shaped housing 3.
The setting of separation clearance 21 helps mussel separator tube 2 to contact and extrude the root of inboard mussel, and round platform shape casing 3 inner wall contacts and extrudes the top of outside mussel again simultaneously, and this structure makes outside mussel and inboard mussel receive round platform shape casing 3 and mussel separator tube 2's effect simultaneously, further improves the mussel picking efficiency of this device.
Specifically, a plurality of cylindrical extrusion rod shells 4 are vertically and fixedly arranged on the inner wall of the round table-shaped shell 3 around the axis of the round table-shaped shell 3; an extrusion rod 41 is inserted in the axial direction of each extrusion rod shell 4, and a second reset spring 42 is also arranged in each extrusion rod shell 4; one end of the second return spring 42 is pressed against the pressing rod 41, and the other end is pressed against the bottom of the pressing rod housing 4.
In the process that mussels enter the round table-shaped shell 3, the extrusion rod 41 is extruded by the mussels and is retracted into the extrusion rod shell 4, and meanwhile the second return spring 42 is compressed. Under the action of the second reset spring 42, the extrusion rod 41 extrudes mussels outside the round table-shaped shell 3, so that gaps between the mussels outside the round table-shaped shell 3 and the mussels inside the round table-shaped shell 3 are increased, the torque action of the round table-shaped shell 3 on the mussels is improved, and the mussel picking efficiency of the device is further improved. Simultaneously, the structure makes the both ends of the cultivation rope 7 in the round platform shape shell 3 receive the stretching, effectively improves the tensioning degree of this part cultivation rope 7, further improves the moment of torsion effect of round platform shape shell 3 to the mussel.
Specifically, a plurality of cylindrical auxiliary separating rod shells 52 are fixedly arranged on the inner wall of the circular truncated cone-shaped shell 3 around the axis of the circular truncated cone-shaped shell 3, and the axis of each auxiliary separating rod shell 52 is perpendicular to the axis of the circular truncated cone-shaped shell 3; an auxiliary separating rod 5 is axially inserted into the auxiliary separating rod housing 52, and a third return spring 53 is further arranged in the auxiliary separating rod housing 52; one end of the third return spring 53 is propped against the auxiliary separating rod 5, and the other end is propped against the bottom of the auxiliary separating rod shell 52; an auxiliary separating knife 51 is fixedly arranged on the end part of the auxiliary separating rod 5 extending out of the auxiliary separating rod shell 52; the auxiliary separating blade 51 is directed toward the small diameter end of the circular-truncated-cone-shaped housing 3.

The auxiliary separating blade 51 is inserted into the slit of the mussel by the third return spring 53. The mussels are continuously moved by the torque action of the circular truncated cone-shaped housing 3 and the reaction force of the mussel separating tube 2, thereby causing the auxiliary separating rod 5 to make retracting and extending movements. The auxiliary separating knife 51 moves up and down under the drive of the auxiliary separating rod 5, and the auxiliary separating knife 51 enables mussels to be subjected to acting force in the up-down direction, so that the mussel picking efficiency of the device is further improved.
Specifically, an arc-shaped strip 411 is fixedly arranged at the end of the extrusion rod 41 extending out of the extrusion rod shell 4, and the plane of the arc-shaped strip 411 is perpendicular to the axis of the truncated cone-shaped shell 3.
The arc strip 411 is arranged to help to increase the contact area between the extrusion rod 41 and mussels, and further increase the gap between the mussels outside the circular truncated cone-shaped shell 3 and the mussels inside the circular truncated cone-shaped shell 3.

B) The inner ends of the movable strips 32 are inserted into gaps among mussels under the action of the first return springs 34;
After the mussels enter the truncated cone-shaped shell 3, the outside mussels contact and press the movable strip 33. The movable bar 33 drives the movable bar connecting rod 33 to move outwards of the truncated cone-shaped shell 3, and simultaneously compresses the first reset spring 34. The compressed first return spring 34 causes the movable bar 33 to have a movement tendency toward the axis of the truncated cone-shaped housing 3. The mussel in the outside separates, drops from inboard mussel under round platform shape casing 3 effort and moment of torsion effect, also makes inboard mussel loose simultaneously, and the gap between the mussel increases, thereby helps the mussel on the movable strip 33 inner intubate further loose string 7 in the gap of mussel, helps improving the mussel picking efficiency of this device. After the mussel is separated from the culture rope 7 and falls, the movable strip 33 extrudes the falling mussel under the action of the first reset spring 34, so that the mussel is helped to be discharged out of the round table-shaped shell 3, and the mussel is accelerated to be discharged.
C) The extrusion rod 41 extrudes mussels outside the truncated cone-shaped shell 3 under the action of the second return spring 42;
In the process that mussels enter the round table-shaped shell 3, the extrusion rod 41 is extruded by the mussels and is retracted into the extrusion rod shell 4, and meanwhile the second return spring 42 is compressed. Under the action of the second reset spring 42, the extrusion rod 41 extrudes mussels outside the round table-shaped shell 3, so that gaps between the mussels outside the round table-shaped shell 3 and the mussels inside the round table-shaped shell 3 are increased, the torque action of the round table-shaped shell 3 on the mussels is improved, and the mussel picking efficiency of the device is further improved. Simultaneously, the structure makes the both ends of the cultivation rope 7 in the round platform shape shell 3 receive the stretching, effectively improves the tensioning degree of this part cultivation rope 7, further improves the moment of torsion effect of round platform shape shell 3 to the mussel.
D) The auxiliary separating knife 51 is inserted into a gap between mussels under the action of a third return spring 53;
After mussels enter the truncated cone-shaped shell 3, the auxiliary separating knife 51 is extruded by the mussels, the auxiliary separating rod 5 is retracted into the auxiliary separating rod housing 52, and the third return spring 53 is compressed. The auxiliary separating blade 51 is inserted into the slit of the mussel by the third return spring 53. The mussels are continuously moved by the torque action of the circular truncated cone-shaped housing 3 and the reaction force of the mussel separating tube 2, thereby causing the auxiliary separating rod 5 to make retracting and extending movements. The auxiliary separating knife 51 moves up and down under the drive of the auxiliary separating rod 5, and the auxiliary separating knife 51 enables mussels to be subjected to acting force in the up-down direction, so that the mussel picking efficiency of the device is further improved.
Step five: the front end of the culture rope 7 enters a mussel separation tube 2, and the mussel separation tube 2 separates inner mussels on the culture rope 7;
As the culture rope 7 moves forward into the mussel separating tube 2, the root of the inner mussel is contacted with the end of the mussel separating tube 2 and is extruded; under the action of the end part of the mussel separating tube 2, the inner mussels are separated from the culture ropes 7. Outside mussel and inboard mussel receive round platform shape casing 3 and mussel separator tube 2's effect simultaneously, further improve the mussel of this device and pick efficiency.
Step six: the separated mussels are discharged from the through groove 31.
