[0003] In view of the above problems, the application number 2018114635696 discloses a fish posture adjusting device, which comprises a vibration rack, the vibration rack comprises a support frame; a vibration device, the vibration device comprises a vibration motor arranged on the side of the support frame; a vibration table structure, the vibration table structure comprises a vibration slide arranged on the top of the support frame, and a fish outlet chute connected to the end of the vibration slide; the vibration slide gradually inclines and extends towards the direction of the fish outlet chute, and the height of the fish outlet chute is lower than the height of the vibration slide; the width of the vibration slide gradually narrows towards the direction of the fish outlet chute, or / and the width of the fish outlet chute gradually narrows towards the end of the fish outlet chute, and the width of the fish outlet chute is not greater than the width of the vibration slide.

[0004] Although the above-mentioned device can distinguish and adjust the head and tail of the fish on the assembly line, improve the efficiency of fish pre-processing treatment flow operation, but in actual use process, the overall structure of the device is complex, the parameter adjustment steps are tedious, and the accuracy rate of head and tail orientation is low, so it is not suitable for processing of large quantities of fish. SUMMARY

[0005] The purpose of the present application is to provide a fish directional conveying tank, which has the advantages of simple structure, convenient operation, and can realize the effect of directional conveying of large quantities of fish.

[0006] The technical problem of the present application is solved by the following technical scheme: a fish directional conveying tank, comprising a tank body, a water pressure impact device, a water circulation device and a fish output device, the water pressure impact device comprises a water outlet pipe and a water suction pipe fixed to the upper edge of the tank body, a water pump with an output end and an input end connected to the water outlet pipe and the water suction pipe respectively, a water jet pipe vertically connected to the nozzle of the water outlet pipe, and a plurality of water jet holes opened in the side wall of the water jet pipe and spaced in parallel; the water circulation device comprises a high baffle and a low baffle fixed inside the tank body, and a circulating water pipe fixed outside the tank body, the high baffle and the low baffle are respectively close to both ends of the tank body, and the tank body is sequentially divided into a water supply tank, a water flow tank and a water discharge tank, the two ends of the circulating water pipe are respectively communicated with the water supply tank and the water discharge tank, the water suction pipe is located in the water supply tank, and the nozzle thereof is close to the tank bottom of the water supply tank, the water jet pipe is located in the water flow tank and is parallel to the side of the high baffle, and the water jet holes of the water jet pipe are directed to the low baffle; the fish output device comprises a belt conveyor obliquely arranged in the tank body, and a plurality of fish conveying channels arranged in parallel on the surface of the belt conveyor, the two ends of the belt conveyor are respectively located on both sides of the low baffle, and the upper end extends out of the tank body and the lower end extends into the bottom of the water flow tank, and the width of the fish conveying channel is only enough for a single fish with its head forward to pass through.

[0007] By adopting the above technical scheme, when the fish ends the scale removal process, it will enter from one end of the water flow tank in a dizzy or dead state. Since the water suction pipe of the water impact device extends into the water supply tank between the high baffle and the one end of the tank body, the water outlet pipe and the water jet pipe extend into the water flow tank between the high baffle and the low baffle, and the two ends of the circulating water pipe are communicated with the water supply tank and the water discharge tank, under the operation of the water pump, all the water in the tank body will continuously circulate out of the water discharge tank, and overflow into and spray into the water flow tank from the top of the water supply tank and the water jet holes of the water jet pipe, thereby forming a certain flow rate of water flow in the water flow tank. At the same time, when the fish in a dizzy or dead state enters the water flow tank, it will quickly float on the water surface of the water flow tank. Since the fish in a dizzy or dead state floats on the calm water surface in a state of head up, tail down and belly up, under the action of the water flow in the water flow tank, the floating fish will not only move towards the direction of the belt conveyor, but also naturally adjust its position and change to a state of head forward, tail down and belly up. Finally, the fish will enter the fish conveying channel in this posture. Since the fish conveying channel is parallel to the belt surface of the belt conveyor and its width is only enough for a single fish with its head forward to pass through, under the operation of the belt conveyor, the fish will be directional conveyed out of the tank body along the fish conveying channel in this posture, and accurately and effectively enter the next dissection process.

[0008] The fish body conveying channel comprises a pair of fish body limiting plates sliding in the groove body and perpendicular to the surface of the belt conveyor belt, a pair of fish body guide plates with one end of each fish body guide plate being connected to the lower end of the two fish body limiting plates, and an adjusting assembly adjusting the spacing between the two fish body limiting plates.

[0009] By adopting the above technical scheme, the fish body limiting plate can effectively limit the two sides of the fish body, so that the fish body maintains a posture with the head facing forward and is conveyed on the belt conveyor in a directional manner; the fish body guide plate can effectively guide the fish body in the water flow tank into each pair of fish body limiting plates, so as to ensure that the fish body quickly and accurately enters the gap between the two fish body limiting plates; and the adjusting assembly can adjust the height of the two fish body limiting plates, so as to ensure that the fish body conveying channel can adapt to the directional conveying of fish of different sizes and types. Since one end of the fish body guide plate of each fish body conveying channel is hinged in the groove body through the hinge shaft and the support frame one, and the fish body guide plate and the fish body limiting plate are connected through the flexible waterproof cloth, after the adjusting assembly adjusts the thickness of the two fish body limiting plates, the fish body guide plate will also correspondingly expand or reduce the flow area, so as to ensure that fish bodies of various sizes quickly enter the gap of the fish body limiting plate.

[0010] The adjusting assembly comprises a pair of sliding rods fixed on the top of the groove body and the rack of the belt conveyor respectively, a plurality of sliding sleeves sliding on the sliding rods and fixedly connected to the fish body limiting plates, and locking screws respectively threadedly connected to the sliding sleeves and capable of locking the sliding of the sliding sleeves. The two sliding rods are respectively close to the upper and lower ends of the belt conveyor.

[0011] By adopting the above technical scheme, when the size of the fish seed is large or small, the locking screws on the two sliding sleeves are first loosened, then the two sliding sleeves on the sliding rods are manually pushed, so that the two fish body limiting plates are respectively close to or away from each other, and finally, after the spacing between the two fish body limiting plates is appropriate, the locking screws are tightened to lock the sliding of the sliding sleeves, that is, the spacing adjustment of the fish body limiting plates is completed.

[0012] The further arrangement of the present application is that the water discharge pipe comprises a hose and a hard pipe, the hard pipe is fixedly connected with the water spraying pipe, the two ends of the hose are respectively connected with the hard pipe and the water pump, the top of the tank body is provided with a lifting assembly for adjusting the height of the hard pipe and the water spraying pipe, the lifting assembly comprises a square frame fixedly installed on the top edge of the tank body, a pair of guide shafts vertically installed in the square frame, a pair of guide shaft support one slidingly installed on the two guide shafts, a support plate fixedly installed on the two guide shaft support one, a plurality of pipe clamp seats for fixing the hard pipe are installed on the support plate, and the two ends of the guide shaft are fixedly connected with the square frame through guide shaft support two.

[0013] By adopting the above technical scheme, the height of the water spraying pipe in the water flow tank can be adjusted by manually adjusting the height of the guide shaft support one and the support plate on the guide shaft according to the water flow in the water flow tank, so as to ensure the water flow in the water flow tank, safely and effectively drive the fish body to move and adjust the posture to enter the fish body conveying channel. The square frame, the guide shaft support two and the pipe clamp seat can facilitate the maintenance and disassembly of the water discharge pipe and the water spraying pipe.

[0014] The further arrangement of the present application is that the tank body in the water flow tank is also provided with a fish body anti-blocking device, the fish body anti-blocking device is located between the water spraying pipe and the belt conveyor, the fish body anti-blocking device comprises a plurality of six-prism flow dividing tables fixedly installed at the bottom of the water flow tank and having sharp ends and wide middle parts, a fixed flow dividing plate fixedly installed at the top of the six-prism flow dividing table and having a shape consistent with the contour of the head and the middle part of the six-prism flow dividing table, a pair of rotating shafts one vertically and rotatably connected with the top of the six-prism flow dividing table and located at the sharp corners of the tail of the six-prism flow dividing table, a movable flow dividing plate fixedly connected with the rotating shafts one, a fixed shaft one fixedly installed in parallel at the top of the six-prism flow dividing table and located at the middle part of the fixed flow dividing plate, a conical sleeve rotatably installed on the fixed shaft one, four blades uniformly fixedly connected with the side wall of the conical sleeve, a fish blocking disc one rotatably installed on the conical sleeve and fixedly connected with the end of the conical sleeve, a fish blocking disc two rotatably installed on the fixed shaft one and located at the sharp end of the conical sleeve, a fish releasing opening opened in the fish blocking disc two and corresponding to the gap between adjacent blades, a fish releasing chute obliquely fixedly installed at the top of the six-prism flow dividing table and having an upper end aligned with the fish releasing opening, a rotating assembly one for driving the rotating shafts one to rotate, a rotating assembly two for driving the fish blocking disc one to rotate relative to the fixed shaft one, and a rotating assembly three for driving the fish blocking disc two to rotate relative to the fixed shaft, one end of the fish releasing chute away from the fish blocking disc two is located between adjacent six-prism flow dividing tables, the gaps between the six-prism flow dividing tables and the side wall of the tank body correspond to the entrances of the respective fish body conveying channels, and the head of the six-prism and the end of the conical sleeve are close to the entrances of the fish body conveying channels, the outer diameters of the fish blocking disc one and the fish blocking disc two are consistent, and the side of the blade away from the conical sleeve does not exceed the outer contour line of the fish blocking disc one or the fish blocking disc two.

[0015] When a large number of fish enter the flow tank, the fish are divided into multiple groups and pass through the gaps between adjacent six-prism shunt tables, the gaps between the six-prism shunt tables and the inner walls of the tank body, and safely and orderly enter the fish conveying channels. If the fish are blocked at the entrances of the gaps, the rotating assembly one drives the rotating shaft one to rotate first, so that the movable shunt plate blocked at the entrance is flipped over the conical sleeve. At the same time, the rotating assembly three drives the fish blocking disc two to rotate, so that the fish releasing opening and the movable shunt plate on the fish blocking disc two are opened to form a gap between the conical sleeve and the blade. Then, part of the fish blocked at the entrance enters the gap, thereby relieving the blockage at the entrance. After the fish are relatively orderly, the rotating assembly one and the rotating assembly three drive the rotating shaft one and the fish blocking disc two to rotate in the opposite direction, and the initial state is restored. Finally, the rotating assembly two drives the fish blocking disc one to rotate, so that the fish in the gap between the conical sleeve and the blade are flipped to above the conical sleeve. Since the top of the conical sleeve is inclined and the lower end of the conical sleeve is aligned with the fish releasing opening and the upper end of the fish releasing chute of the fish blocking disc two, the fish on the top of the conical sleeve will naturally slide out of the gap between the conical sleeve and the blade, and then pass through the fish releasing opening and the fish releasing chute of the fish blocking disc two to return to the front of the entrance again, so as to perform directional conveying of the fish again. The fish blocking disc one and the fish blocking disc two not only ensure that the fish entering the gap enter the gap between the fixed guide plate and the movable guide plate, but also cooperate with the rotation of the conical sleeve to flip the fish in the gap to the top of the conical sleeve while carrying part of the water to the top of the conical sleeve. The part of the water will carry the fish out of the conical sleeve, the fish releasing opening and the fish releasing chute, thereby ensuring that the fish quickly return to the flow tank for directional conveying.

[0016] The rotating assembly one includes a pair of rotating shafts two rotating at the bottom of the tank body, a pair of complete pinions fixed on the two rotating shafts two respectively, a worm gear and worm reduction motor one fixedly installed at the bottom of the tank body, an incomplete gear fixedly installed at the output end of the worm gear and worm reduction motor one and engaged with the two complete pinions, a pair of worms fixed on the two rotating shafts two respectively, and a pair of worm gears engaged with the two worms respectively. One end of the rotating shaft one rotates through the shunt table and the bottom of the tank body and is fixedly connected with the worm gear. The incomplete gear is located in the middle of the complete pinions, and half a circle of teeth of the incomplete gear is engaged with the complete pinions. The half a circle of teeth of the incomplete gear is located on one side of the two complete pinions before rotation.

[0017] When one rotating shaft one on the six-prism shunt table needs to be driven to rotate, first, the worm gear reduction motor one is started to drive the incomplete gear to rotate by ninety degrees, so that the half-circle gear teeth of the incomplete gear mesh with the complete pinion on one side to rotate, then the complete pinion drives the worm to mesh with the worm gear through the rotating shaft two, and finally the worm gear drives the rotating shaft one connected thereto to rotate; when the other rotating shaft one on the six-prism shunt table needs to be driven to rotate, the worm gear reduction motor one is only needed to be started to drive the incomplete gear to rotate reversely by ninety degrees, so that the half-circle gear teeth on the incomplete gear mesh with the complete pinion on the other side to rotate, and then the other rotating shaft two, the worm and the worm gear can drive the other rotating shaft one to rotate. In the process of the half-circle gear teeth of the incomplete gear meshing with the complete pinion on one side, since the other half-circle gear teeth of the incomplete gear are not meshed, and the rotation angle is not more than one hundred and eighty degrees each time, when the complete pinion on one side drives the rotating shaft one connected thereto to rotate, the complete pinion on the other side does not rotate and does not drive the rotating shaft one connected thereto to rotate, so that the two rotating shafts on the six-prism shunt table are driven by the same driving energy source and do not affect the working effect of each other.

[0018] Further, the rotating assembly two comprises a rotating cylinder one fixed to one side of the fish blocking disc one and rotationally connected with the fixed shaft one, a rotating shaft three vertically rotating through the six-prism shunt table and the bottom of the groove body, a pair of bevel gears one fixedly installed on the rotating cylinder one and the rotating shaft three respectively and meshing with each other, and a worm gear reduction motor two fixed to the bottom of the groove body and having an output end connected with the lower end of the rotating shaft three.

[0019] Further, the rotating assembly two comprises a rotating cylinder one fixed to one side of the fish blocking disc one and rotationally connected with the fixed shaft one, a rotating shaft three vertically rotating through the six-prism shunt table and the bottom of the groove body, a pair of bevel gears one fixedly installed on the rotating cylinder one and the rotating shaft three respectively and meshing with each other, and a worm gear reduction motor two fixed to the bottom of the groove body and having an output end connected with the lower end of the rotating shaft three.

[0020] Further, the rotating assembly three comprises a rotating cylinder two fixed to one side of the fish blocking disc two and rotationally connected with the fixed shaft one, a rotating shaft four vertically rotating through the six-prism shunt table and the bottom of the groove body, a rotating shaft five rotating on the bottom of the groove body and connected with the output end of the worm gear reduction motor one, a pair of bevel gears two fixedly installed on the rotating shaft four and the rotating cylinder two respectively and meshing with each other, and a pair of bevel gears three fixedly installed on the rotating shaft four and the rotating shaft five respectively and meshing with each other, wherein the rotating shaft five is located between the two rotating shafts two, and the incomplete gear is fixedly installed on the rotating shaft five.

[0021] When the worm gear reducer one drives the incomplete large gear to rotate, the rotating shaft five will drive the rotating shaft four to rotate through the two mutually meshing bevel gears three, then the rotating shaft four will drive the rotating cylinder two to rotate through the two mutually meshing bevel gears two, and finally the rotating cylinder two drives the fish baffle two connected thereto to rotate. When the worm gear reducer one drives the incomplete large gear to rotate, the rotating shaft one will drive the movable shunt plate of the six-prism shunt table to flip, and the rotating cylinder two will drive the fish baffle two to rotate towards the direction of the movable shunt plate being flipped at this time through the transmission of the rotating shaft four, the rotating shaft five and the bevel gears, so that the synchronous work of the movable shunt plate and the fish baffle two is realized.

[0022] The six-prism shunt table top is vertically fixed with a pair of square cylinder bodies supporting and fixing the two ends of the fixed shaft one, the two ends of the fixed shaft one are fixed through the side walls of the two square cylinder bodies, the rotating cylinder one and the rotating cylinder two rotate into the square cylinder bodies, the part of the rotating shaft three and the rotating shaft four and the whole of the bevel gear one and the bevel gear two are located in the square cylinder bodies, and the upper end of the fish releasing chute is fixedly connected with the top end of the square cylinder body.

[0023] Through the above technical scheme, the square cylinder body can not only support the fixed shaft one and the upper end of the fish releasing chute, but also avoid the parts such as the bevel gears and the rotating shafts from being soaked in water, so as to effectively guarantee the stable transmission and safe transmission of them; the support frame two and the U-shaped hanging frame can support the lower end of the fish releasing chute, so as to guarantee the structural stability of the fish releasing chute.

[0024] The further setting of the present application is that the groove body is fixedly arranged with trapezoidal shunt tables on the two side walls of the water flow chute, the trapezoidal shunt tables are located on the two sides of the six-prism shunt table, and the top ends of the trapezoidal shunt tables are flush with the top end of the fixed shunt plate.

[0025] Through the above technical scheme, the six-prism shunt table can be matched to further guarantee the stable shunt of the water flow and the fish school.

[0026] The beneficial effects of the present application are:

[0027] 1. Through the water pressure impact device and water circulation device in the tank and other structures, not only can form water flow in the tank, effectively help fish head tail adjustment direction, and cooperate with the fish output device in the belt conveyor and fish conveying channel, also can adjust the fish head direction of fish body output tank in turn, and then reach the effect of fish directional conveying, compared with the traditional mechanical structure type fish body posture adjustment equipment, the directional conveying water tank structure is simple, the accuracy is higher, and various complicated mechanical parameters do not need to be controlled and adjusted.

[0028] 2. Through the fish body limiting plate and fish body guide plate of the fish body conveying channel, not only can effectively cooperate with the belt conveyor to realize the stable directional output of the fish body, but also can simply and conveniently adjust the distance between the fish body limiting plates by using the sliding rod and sliding sleeve of the adjusting assembly, so that the fish output device can adapt to the conveying of fish bodies of various sizes, and the applicability of the structure is effectively improved.

[0029] 3. Through the hexagonal prism shunt table and trapezoidal guide table in the fish body anti-blocking device, and the fixed shunt plate and other structures, not only can help the water flow and fish body group shunt, to avoid the fish body group blocking the entrance of the fish body conveying channel, causing the directional conveying efficiency of the fish body to decrease, and the movable shunt plate, conical sleeve, blade and fish blocking plate in the fish body anti-blocking device can further separate and send back part of the fish group in the gap entrance to the front of the entrance when the fish group blocks the gap entrance between the shunt tables, thereby effectively solving the problem that the fish group is easy to block.

DETAILED DESCRIPTION

[0039] The technical solutions of the present application will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] Embodiment: A fish directional conveying tank, like Figure 1 , Figure 2As shown, including the tank 1, the tank 1 is provided with water pressure impact device 2, water circulation device 3, and fish output device 4, water pressure impact device 2 including fixed on the tank 1 upper edge of the drain pipe 21 and water suction pipe 22, the output end and input end are connected to the water pump 23 of drain pipe 21 and water suction pipe 22, the water jet pipe 24 is vertically connected to the drain pipe 21 pipe orifice, a plurality of water jet holes 241 are opened in the side wall of the water jet pipe 24 and are parallel and spaced; water circulation device 3 includes high partition plate 31 and low partition plate 32 fixed in the tank 1 inside, and circulating water pipe 33 fixed outside the tank 1, high partition plate 31 and low partition plate 32 are respectively close to both ends of the tank 1, and in the tank 1 are sequentially separated into water supply tank 11, water flow tank 12 and drainage tank 13, both ends of the circulating water pipe 33 are communicated with the water supply tank 11 and the drainage tank 13 respectively, the water suction pipe 22 is located in the water supply tank 11, and the orifice thereof is close to the tank bottom of the water supply tank 11, the water jet pipe 24 is located in the water flow tank 12, and is parallel close to one side of the high partition plate 31, the water jet hole 241 of the water jet pipe 24 faces the low partition plate 32; fish output device 4 includes a belt conveyor 41 obliquely arranged in the tank 1, a plurality of fish conveying channels 42 arranged in parallel on the surface of the belt conveyor 41, both ends of the belt conveyor 41 are located on both sides of the low partition plate 32 respectively, and the upper end extends out of the tank 1, and the lower end extends into the bottom of the water flow tank 12, the width of the fish conveying channel 42 is only for a single head forward fish to pass through.

[0041] By adopting the above technical scheme, when the fish ends the descaling process, it will enter from one end of the flow tank 12 in a dizzy or dead state. Since the water suction pipe 22 of the water ram device extends into the water supply tank 11 between the high partition 31 and one end of the tank body 1, the water discharge pipe 21 and the water jet pipe 24 extend into the flow tank 12 between the high partition 31 and the low partition 32, and the circulating water pipe 33 is connected to the water supply tank 11 and the water discharge tank 13 at both ends, therefore under the operation of the water pump 23, all the water in the tank body 1 will continuously circulate from the water discharge tank 13, and then overflow and jet into the flow tank 12 from the top of the water supply tank 11 and the water jet holes 241 of the water jet pipe 24, respectively, thereby forming a certain flow rate of water flow in the flow tank 12. After the fish enters the flow tank 12 in a dizzy or dead state, it will quickly float on the water surface of the flow tank 12. Since the fish in a dizzy or dead state floats on the calm water surface in a state of head up, tail down, and belly up, under the action of the water flow in the flow tank 12, the floating fish will not only move towards the direction of the belt conveyor 41, but also the fish head will naturally adjust its position and change to a state of head forward, tail down, and belly up. Finally, the fish will enter the fish conveying channel 42 in this posture. Since the fish conveying channel 42 is parallel to the surface of the belt of the belt conveyor 41, and its width only allows a single fish with its head forward to pass through, under the operation of the belt conveyor 41, the fish will be conveyed out of the tank body 1 along the fish conveying channel 42 in this posture, and accurately and effectively enter the next evisceration process.

[0042] As Figure 2As shown, the fish body conveying channel 42 comprises a pair of fish body limiting plates 421 sliding in the tank body 1 and perpendicular to the belt surface of the belt conveyor 41, a pair of fish body guide plates 422 with one end of each connected to the lower end of the two fish body limiting plates 421, an adjusting assembly 423 adjusting the spacing between the two fish body limiting plates 421, the end of the fish body guide plate 422 away from the fish body limiting plate 421 is hingedly connected with a hinge shaft 424, and adjacent fish body guide plates 422 of different fish body conveying channels 42 are commonly hingedly connected with the same hinge shaft 424, a support frame one 425 is fixedly arranged at the top of the tank body 1, the upper ends of all hinge shafts 424 are commonly fixedly connected with the support frame one 425, and the fish body guide plate 422 and the fish body limiting plate 421 are connected by a flexible waterproof cloth 426. By adopting the above fish body limiting plate 421, the two sides of the fish body can be effectively limited, so that the fish body maintains the posture of the head facing forward and is directionally conveyed on the belt conveyor 41; by adopting the above fish body guide plate 422, the fish body in the water flow tank 12 can be effectively guided into each pair of fish body limiting plates 421, so as to ensure that the fish body quickly and accurately enters the gap between the two fish body limiting plates 421; by adopting the above adjusting assembly 423, the height of the two fish body limiting plates 421 can be adjusted, so as to ensure that the fish body conveying channel 42 can adapt to the directional conveying of fish of different sizes and types. Since one end of the fish body guide plate 422 of each fish body conveying channel 42 is hingedly connected with the hinge shaft 424 and the support frame one 425 in the tank body 1, and the fish body guide plate 422 and the fish body limiting plate 421 are connected by the flexible waterproof cloth 426, after the above adjusting assembly 423 adjusts the thickness of the two fish body limiting plates 421, the fish body guide plate 422 will also correspondingly expand or shrink the flow area, so as to ensure that fish bodies of various sizes quickly enter the gap of the fish body limiting plate 421.

By adopting the structure of the above adjusting assembly 423, when the size of the fish seed is large or small, first, the locking screws 423c on the two sliding sleeves 423b are loosened, then the two sliding sleeves 423b on the sliding rod 423a are manually adjusted, so that the two fish body limiting plates 421 are close to or away from each other, and finally, after the spacing between the two fish body limiting plates 421 is appropriate, the locking screws 423c are tightened to lock the sliding of the sliding sleeves 423b, that is, the spacing adjustment of the fish body limiting plates 421 is completed.

[0044] As shown in Figure 2 , Figure 6As shown, the drain pipe 21 includes a hose 211 and a hard pipe 212, the hard pipe 212 is fixedly connected with the water jet pipe 24, the hose 211 is respectively connected with the hard pipe 212 and the water pump 23 at two ends, the top of the tank body 1 is provided with a lifting assembly 25 for adjusting the height of the hard pipe 212 and the water jet pipe 24, the lifting assembly 25 includes a square frame 251 fixedly installed on the top edge of the tank body 1, a pair of guide shafts 252 vertically installed in the square frame 251, a pair of guide shaft 252 support I respectively sliding on the two guide shafts 252, a support plate 254 fixedly installed on the two guide shaft 252 support I, a plurality of pipe clamp seats 256 for fixing the hard pipe 212 are installed on the support plate 254, the two ends of the guide shaft 252 are respectively fixed in the square frame 251 through the guide shaft 252 support II, by adopting the connecting structure of the above-mentioned drain pipe 21 and the lifting assembly 25, the staff can manually adjust the height of the guide shaft 252 support I on the guide shaft 252 and the support plate 254 according to the water flow in the water channel 12, to adjust the height of the water jet pipe 24 in the water channel 12, and then to ensure the water flow in the water channel 12, safely and effectively drive the fish body to move and adjust the posture to enter the fish body conveying channel 42. Among them, the square frame 251, the guide shaft 252 support II and the pipe clamp seat can facilitate the staff to overhaul and disassemble the drain pipe 21 and the water jet pipe 24.

[0045] As Figures 2-4As shown, the groove body 1 is located in the water channel 12 and is also provided with a fish body anti-blocking device 5, which is located between the water jet pipe 24 and the belt conveyor 41. The fish body anti-blocking device 5 comprises a plurality of six-prism-shaped fish body distribution tables 51 fixed to the bottom of the water channel 12, with sharp ends and wide middle parts; a fixed distribution plate 511 fixed to the top of the six-prism-shaped fish body distribution table 51 and having a shape consistent with the contour of the head and middle part of the six-prism-shaped fish body distribution table 51; a pair of rotating shafts I 52 vertically connected to the top of the six-prism-shaped fish body distribution table 51 and located at the sharp corners of the tail of the six-prism-shaped fish body distribution table 51; a movable distribution plate 521 fixedly connected to one end of the rotating shaft I 52; a fixed shaft I 53 fixedly connected to the top of the six-prism-shaped fish body distribution table 51 and located in the middle part of the fixed distribution plate 511; a conical sleeve 531 rotatably connected to the fixed shaft I 53; four blades 532 fixedly connected to the side wall of the conical sleeve 531; a fish blocking disc I 533 rotatably connected to the conical sleeve 531 and fixedly connected to the end of the conical sleeve 531; a fish blocking disc II 534 rotatably connected to the fixed shaft I 53 and located at the sharp end of the conical sleeve 531; a fish releasing opening 534a formed in the fish blocking disc II 534 and corresponding to the gap between adjacent blades 532; a fish releasing chute 54 obliquely fixed to the top of the six-prism-shaped fish body distribution table 51 and having an upper end aligned with the fish releasing opening 534a; a rotating assembly I 55 for driving the rotating shaft I 52 to rotate; a rotating assembly II 56 for driving the fish blocking disc I 533 to rotate relative to the fixed shaft I 53; a rotating assembly III 57 for driving the fish blocking disc II 534 to rotate relative to the fixed shaft; and one end of the fish releasing chute 54 away from the fish blocking disc II 534 is located between adjacent six-prism-shaped fish body distribution tables 51. The gap between the six-prism-shaped fish body distribution table 51 and the side wall of the groove body 1 corresponds to the inlet of each fish body conveying channel 42, and the head of the six-prism and the end of the conical sleeve 531 are close to the inlet of the fish body conveying channel. The outer diameter of the fish blocking disc I 533 or the fish blocking disc II 534 is consistent, and the side of the blade 532 away from the conical sleeve 531 does not exceed the outer contour line of the fish blocking disc I 533 or the fish blocking disc II 534.

[0046] When a large number of fish enter the flow tank 12, the fish will be divided into multiple groups and pass through the gaps between adjacent hexagonal flow dividing tables 51, the gaps between the hexagonal flow dividing tables 51 and the inner walls of the tank body 1, and enter the fish conveying passages 42 in a safe and orderly manner. If the fish are blocked at the entrances of the gaps, the rotating assembly one 55 drives the rotating shaft one 52 to rotate first, causing the movable flow dividing plate 521 at the blocked entrance to flip over the conical sleeve 531. At the same time, the rotating assembly three 57 drives the fish blocking disc two 534 to rotate, causing the fish releasing opening 534a and the movable flow dividing plate 521 to open a gap to the gap between the conical sleeve 531 and the blade 532. Then, part of the fish group at the blocked entrance will enter the gap, thereby relieving the blockage at the entrance. After the fish are relatively orderly, the rotating assembly one 55 and the rotating assembly three 57 drive the rotating shaft one 52 and the fish blocking disc two 534 to rotate in the opposite direction, thereby restoring the initial state. Finally, the rotating assembly two 56 drives the fish blocking disc one 533 to rotate, causing the fish in the gap between the conical sleeve 531 and the blade 532 to flip over to the top of the conical sleeve 531. Since the top of the conical sleeve 531 is inclined and the lower end of the conical sleeve 531 is aligned with the fish releasing opening 534a of the fish blocking disc two 534 and the upper end of the fish releasing chute 54, the fish at the top of the conical sleeve 531 will naturally slide out of the gap between the conical sleeve 531 and the blade 532 and pass through the fish releasing opening 534a and the fish releasing chute 54 of the fish blocking disc two 534 to return to the front of the entrance again, and the water flow directional conveying of the fish is performed again. The fish blocking disc one 533 and the fish blocking disc two 534 not only ensure that the fish entering the gap enter the gap between the fixed flow guide plate and the movable flow guide plate, but also cooperate with the rotation of the conical sleeve 531 to flip the fish in the gap to the top of the conical sleeve 531 while carrying part of the water to the top of the conical sleeve 531. The part of the water will carry the fish out of the conical sleeve 531, the fish releasing opening 534a, and the fish releasing chute 54, thereby ensuring that the fish quickly return to the directional conveying flow tank 12. The tank body 1 is fixedly provided with trapezoidal flow dividing tables 6 on both side walls of the flow tank 12. The trapezoidal flow dividing tables 6 are located on both sides of the hexagonal flow dividing tables 51 and are flush with the top ends of the fixed flow dividing plates 511. The trapezoidal flow dividing tables 6 cooperate with the hexagonal flow dividing tables 51 to further ensure the stable flow and fish group division.

[0047] As Figure 4 , Figure 7As shown, the rotating assembly one 55 includes a pair of rotating shafts two 551 rotating at the bottom of the groove body 1, a pair of complete pinions 552 fixed on the two rotating shafts two 551 respectively, a worm gear and worm reducer motor one 553 fixedly installed at the bottom of the groove body 1, an incomplete gear 554 fixed at the output end of the worm gear and worm reducer motor one 553 and engaged with the two complete pinions 552, a pair of worms 555 fixed on the two rotating shafts two 551 respectively, and a pair of worm gears 556 engaged with the two worms 555 respectively. One end of the rotating shaft one 52 rotates through the flow dividing table and the bottom of the groove body 1 and is fixedly connected with the worm gear 556. The incomplete gear 554 is located in the middle of the complete pinion 552, and the half-toothed gear of the incomplete gear 554 engages with the complete pinion 552. When it is necessary to drive one rotating shaft one 52 on the six-prism flow dividing table 51 to rotate, the worm gear and worm reducer motor one 553 is first started to drive the incomplete gear 554 to rotate by ninety degrees, so that the half-toothed gear of the incomplete gear 554 engages with the complete pinion 552 on one side to rotate. Then the complete pinion 552 will drive the worm 555 to engage with the worm gear 556 through the rotating shaft two 551. Finally, the worm gear 556 will drive the connected rotating shaft one 52 to rotate. When it is necessary to drive the other rotating shaft one 52 on the six-prism flow dividing table 51 to rotate, the worm gear and worm reducer motor one 553 is only needed to be started to drive the incomplete gear 554 to rotate reversely by ninety degrees, so that the half-toothed gear on the incomplete gear 554 engages with the complete pinion 552 on the other side to rotate. Through the other rotating shaft two 551, the worm 555 and the worm gear 556, the other rotating shaft one 52 can be driven to rotate. In the process of engaging the half-toothed gear of the incomplete gear 554 with the complete pinion 552 on one side, since the other half of the incomplete gear 554 has no tooth, and the rotation angle is not more than one hundred and eighty degrees each time, when the complete pinion 552 on the side drives the rotating shaft one 52 to rotate, the complete pinion 552 on the other side will not rotate and will not drive the rotating shaft one 52 to rotate, thereby realizing that the two rotating shafts one 52 on the six-prism flow dividing table 51 are driven by the same driving source and will not affect the working effect of each other.

[0048] As Figure 4As shown, the rotating assembly two 56 includes a rotating cylinder one 561 fixed to one side of the fish blocking plate one 533 and rotatably connected to the fixed shaft one 53, a rotating shaft three 562 vertically rotating through the six-prism flow dividing table 51 and the bottom of the tank body 1, a pair of bevel gears one 563 fixedly installed on the rotating cylinder one 561 and the rotating shaft three 562 respectively and meshing with each other, a worm gear and worm reducer motor two 564 fixed to the bottom of the installation tank body 1 and having an output end connected to the lower end of the rotating shaft three 562. When the rotating assembly two 56 is used to drive the fish blocking plate one 533 to rotate, the worm gear and worm reducer motor two 564 is first started to drive the rotating shaft three 562 to rotate, then the rotating shaft three 562 drives the rotating cylinder one 561 to rotate through the two meshing bevel gears one 563, and finally the rotating cylinder one 561 drives the fish blocking plate one 533 connected thereto to rotate. The rotating assembly three 57 includes a rotating cylinder two 571 fixed to one side of the fish blocking plate two 534 and rotatably connected to the fixed shaft one 53, a rotating shaft four 572 vertically rotating through the six-prism flow dividing table 51 and the bottom of the tank body 1, a rotating shaft five 573 rotating on the bottom of the tank body 1 and connected to the output end of the worm gear and worm reducer motor one 553, a pair of bevel gears two 574 fixedly installed on the rotating shaft four 572 and the rotating cylinder two 571 respectively and meshing with each other, a pair of bevel gears three 575 fixedly installed on the rotating shaft four 572 and the rotating shaft five 573 respectively and meshing with each other, the rotating shaft five 573 is located between the two rotating shafts two 551, and the incomplete gear wheel 554 is fixedly installed on the rotating shaft five 573. When the rotating assembly three 57 is used, the worm gear and worm reducer motor one 553 drives the incomplete gear wheel 554 to rotate, the rotating shaft five 573 drives the rotating shaft four 572 to rotate through the two meshing bevel gears three 575, then the rotating shaft four 572 drives the rotating cylinder two 571 to rotate through the two meshing bevel gears two 574, and finally the rotating cylinder two 571 drives the fish blocking plate two 534 connected thereto to rotate. When the worm gear 556 and the worm 555 of the reducer one drive the half-tooth mesh of the incomplete gear wheel 554 to mesh and drive in the direction of the complete pinion gear 552 on one side thereof, the rotating shaft one 52 driven thereby will drive the movable flow dividing plate 521 of the six-prism flow dividing table 51 to flip, and at the same time, the rotating cylinder two 571 will drive the fish blocking plate two 534 to rotate in the direction of the movable flow dividing plate 521 being flipped at the moment through the transmission of the rotating shaft four 572, the rotating shaft five 573 and the bevel gears, thereby realizing the synchronous work of the movable flow dividing plate 521 and the fish blocking plate two 534.

[0049] As Figure 2 , Figure 4As shown, the top of the hexagonal prism distribution platform 51 is vertically fixed with a pair of square cylinder 58 supporting fixed shaft one 53 at both ends. The both ends of the fixed shaft one 53 are fixed through the sidewall of the two square cylinders 58. The rotating cylinder one 561 and the rotating cylinder two 571 are rotatably arranged in the square cylinder 58. The part of the rotating shaft three 562 and the rotating shaft four 572 and the whole of the bevel gear one 563 and the bevel gear two 574 are located in the square cylinder 58. The upper end of the fish releasing chute 54 is fixedly connected with the top of the square cylinder 58. By using the square cylinder 58, the fixed shaft one 53 and the upper end of the fish releasing chute 54 can be supported. Moreover, the parts such as the bevel gears and the rotating shafts can be prevented from being soaked in water, so that the transmission stability and safety of the parts can be effectively ensured. The top of the groove body 1 is fixedly provided with a support frame two 59. The bottom of the support frame two 59 is fixedly connected with a U-shaped hanging frame 591 which hangs the lower end of the fish releasing chute 54. By using the support frame two 59 and the U-shaped hanging frame 591, the lower end of the fish releasing chute 54 can be supported, so that the structural stability of the fish releasing chute 54 can be ensured.
