Description

Technical Field

[0001] This invention relates to the field of suspended conveying devices, specifically a conveyor for aquatic plants used in shrimp and crab farming. Background Technology

[0002] The aquatic plants artificially planted or maintained in shrimp and crab ponds are mainly submerged plants. Their core functions are to purify water quality, increase oxygen, provide habitats and molting sites, serve as natural food, and provide shade and cooling. They are like underwater forests for shrimp and crab farming. In the scenarios of industrialized recirculating aquaculture, large-scale outdoor pond farming, and deep-water cage farming of shrimp and crabs, aquatic plants serve as water purification carriers, hiding places, and natural food. Their transportation and placement have long relied on manual handling, ground belt conveyors, or simple throwing equipment.

[0003] Currently, when using aquatic plant conveyors in shrimp and crab farming, the aquatic plants often require manual handling and repositioning after transport. However, manual handling of aquatic plants is labor-intensive and inefficient. Furthermore, relying on conveyor belt devices makes it difficult to ensure precise distribution of aquatic plants within the farming pond, easily leading to localized accumulation or blank areas. This affects water quality control and the stability of the shrimp and crab habitat. Additionally, existing conveyor belt systems are prone to aquatic plant accumulation, making it difficult to guarantee uniform distribution.

[0004] To address the above issues, a water plant conveyor for shrimp and crab farming is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a water plant conveyor for shrimp and crab farming. By using this device, the problems mentioned above are solved, such as the difficulty in ensuring accurate distribution of water plants in the farming pond when using existing conveyor belt devices to transport water plants, and the easy accumulation of water plants, making it difficult to ensure uniform distribution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveyor for aquatic plants in shrimp and crab farming, comprising a suspended conveyor and a placement platform fixed to one side below the suspended conveyor. A plurality of placement cylinders are installed on the suspended conveyor, and a receiving frame is provided at the bottom of the placement cylinders and the receiving frame is fixed to the suspended conveyor. An inlet is fixed to one side above the placement cylinders. An electric pusher cylinder is fixed on one side of the receiving frame, and a toothed plate is fixed at the output end of the electric pusher cylinder. A material drop port is opened on the inner surface of the receiving frame. An industrial camera is fixed on one side inside the receiving frame. A material feeding mechanism is installed inside the placement cylinder. Material feeding mechanisms are installed on both sides of the surface of the receiving frame.

[0007] Furthermore, the overhead conveyor includes a power motor installed behind the placement platform, and the output end of the power motor is connected to a lower tooth seat, and an upper tooth seat is provided on the top of the lower tooth seat. A suspension chain is connected to the outside of the upper tooth seat, and several suspension rods are fixed to the bottom of the suspension chain.

[0008] Furthermore, the placement cylinder includes a toothed ring disposed on one side of the toothed plate, a rotating sleeve fixed above the toothed ring, and the toothed ring and the rotating sleeve are rotatably mounted on the placement cylinder. A rotating groove is provided above the inner surface of the placement cylinder, and connecting rods are fixed on both sides above the rotating sleeve.

[0009] Furthermore, the feeding mechanism includes a rotating seat rotatably mounted at the bottom of the suspension rod, and a fixed sleeve is fixed at the bottom of the rotating seat. The fixed sleeve is internally threaded with a meshing block, a lifting rod is fixed at the bottom of the meshing block, and a sealing block is fixed at the bottom of the lifting rod.

[0010] Furthermore, a second protrusion is fixed on the upper surface of the gear ring, and the second protrusion is spherical.

[0011] Furthermore, the bottom of the placement cylinder is fixed with several protrusions 2 in a ring shape, and protrusion 1 is arranged between two adjacent protrusions 2.

[0012] Furthermore, a rubber sleeve is fixed below the inner surface of the placement cylinder, and the bottom of the rubber sleeve is fixed on the toothed ring. A telescopic column is installed in the middle of the suspension rod.

[0013] Furthermore, the material feeding mechanism includes rotating gears rotatably mounted on both sides of the receiving frame, and a fixed shaft is fixed to the bottom of the rotating gears. A toothed plate is meshed on one side of the rotating gears, and the toothed plate is fixed on the placement cylinder.

[0014] Furthermore, a reverse lead screw is fixed to the bottom of the fixed shaft, and limit plates are fixed to both the upper and lower ends of the reverse lead screw.

[0015] Furthermore, the external thread of the reverse lead screw is connected to a sliding sleeve, and a material-pulling plate is fixed to the outer annular part of the sliding sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention enables automated and precise operation of aquatic plant transportation and placement, significantly improving the efficiency of aquatic plant feeding and the standardization of aquaculture management. At the same time, by utilizing the advantages of suspended conveying in three-dimensional operation, it does not occupy ground operation space, reduces the frequency of manual contact with aquatic plants, reduces labor costs, and improves the uniformity of aquatic plant placement, which is conducive to improving the efficiency of large-scale aquaculture.

[0017] This invention utilizes the effect of vibration to accelerate the feeding of aquatic plants, prevent the aquatic plants from accumulating and clogging inside the placement cylinder, thereby improving the stability of automatic feeding, ensuring the effect of shrimp and crab farming, and at the same time avoiding material blockage affecting the stability of the suspended conveyor.

[0018] This invention can disperse the falling aquatic plants, thereby making the coverage of the falling aquatic plants more uniform and improving the effect of shrimp and crab farming. At the same time, the feeding plate can also disperse the aquatic plants that have not fallen in the receiving frame, thereby preventing the aquatic plants from accumulating in the receiving frame and avoiding interference with the subsequent delivery of the placement cylinder.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical challenge of ensuring precise distribution of aquatic plants within the aquaculture pond when using conveyor belt systems for transporting aquatic plants, such as... Figures 1-4 As shown, the following preferred technical solutions are provided: A conveyor for aquatic plants in shrimp and crab farming includes a suspended conveyor 1 and a placement platform 2 fixed to one side below the suspended conveyor 1. Several placement cylinders 3 are mounted on the suspended conveyor 1, and a receiving frame 4 is provided at the bottom of each placement cylinder 3 and fixed to the suspended conveyor 1. An inlet 20 is fixed to one side of the upper part of each placement cylinder 3, through which aquatic plants can be added to the placement cylinder 3. The suspended conveyor 1 is a conventional suspended conveying device, installed in the shrimp and crab farming area, and can suspend and convey multiple sets of placement cylinders 3, thereby transporting aquatic plants for shrimp and crab farming. The suspended conveyor 1 can cross ditches and field ridges, realizing the transport of aquatic plants from the pond to the field. Direct transport from the shore eliminates the need for additional channel construction or transshipment. Aquatic plants are transported within the placement cylinder 3, and this, combined with suspended transport, prevents them from slipping or being blown away by the sea breeze. An electric pusher cylinder 5 is fixed to one side of the receiving frame 4, and a toothed plate 6 is fixed to the output end of the electric pusher cylinder 5. A discharge port 9 is opened on the inner surface of the receiving frame 4, serving as a discharge port above the shrimp and crab farming area. An industrial camera 10 is fixed to one side of the inside of the receiving frame 4. The industrial camera 10 is a conventional vision sensor, and the industrial camera 10, the suspended conveyor 1, and the electric pusher cylinder 5 are all controlled by external control equipment, which is not shown in the figure.

[0023] The placement cylinder 3 is equipped with a feeding mechanism 7. When aquatic plants need to be placed in the aquaculture area at the bottom of the feeding port 9, the industrial camera 10 set on one side of the feeding port 9 can identify the suspended placement cylinder 3. When the placement cylinder 3 is detected, the electric push cylinder 5 will automatically push out the toothed plate 6, so that the toothed plate 6 cooperates with the placement cylinder 3, and finally the feeding mechanism 7 can move down. At this time, the feeding mechanism 7 will open the bottom of the placement cylinder 3, so that the aquatic plants stored in the placement cylinder 3 can fall automatically. Finally, they will fall automatically from the feeding port 9 to the aquaculture area at the bottom of the receiving frame 4, realizing the automation and precision of aquatic plant transportation and placement, greatly improving the efficiency of aquatic plant feeding and the standardization of aquaculture management. At the same time, by utilizing the three-dimensional operation advantage of suspended transportation, it does not occupy ground operation space, reduces the frequency of manual contact with aquatic plants, reduces labor costs, and improves the uniformity of aquatic plant placement, which is conducive to improving the efficiency of large-scale aquaculture.

[0024] Material-distributing mechanisms 8 are installed on both sides of the surface of the receiving frame 4. The material-distributing mechanisms 8 are located on both sides of the discharge port 9. When the placement cylinder 3 passes through the material-distributing mechanism 8, it will drive the material-distributing mechanism 8 to rotate, so that the material-distributing mechanism 8 rotates on the discharge port 9. Thus, when the water plants are placed and fall from the discharge port 9, the rotating material-distributing mechanism 8 can disperse the water plants, so that the coverage of the water plants is more uniform and the effect of shrimp and crab farming is improved. At the same time, the material-distributing mechanism 8 can also distribute the water plants that have not fallen in the receiving frame 4, so as to avoid the possibility of water plants accumulating in the receiving frame 4 and avoid the problem of water plants that have not fallen in the receiving frame 4 interfering with the subsequent delivery of the placement cylinder 3, thus helping to ensure the stability of the suspended delivery.

[0025] The overhead conveyor 1 includes a power motor 11 installed behind the placement platform 2, and the output end of the power motor 11 is connected to a lower gear seat 12. An upper gear seat 13 is provided on the top of the lower gear seat 12. The servo-type power motor 11 can drive the lower gear seat 12 and the upper gear seat 13 to rotate. A suspension chain 14 is connected to the outside of the upper gear seat 13, and several suspension rods 15 are fixed at the bottom of the suspension chain 14. The placement cylinder 3 is fixed on the suspension rods 15. The power motor 11, the lower gear seat 12, the upper gear seat 13, the suspension chain 14 and the suspension rods 15 constitute an overhead conveyor device based on the existing principle.

[0026] like Figure 3 As shown, the placement cylinder 3 includes a gear ring 31 disposed on one side of the gear plate 6. A rotating sleeve 32 is fixed above the gear ring 31, and the gear ring 31 and the rotating sleeve 32 are rotatably mounted on the placement cylinder 3. A rotating groove 33 is provided above the inner surface of the placement cylinder 3. Connecting rods 34 are fixed on both sides above the rotating sleeve 32. The vertical width of the rotating groove 33 is greater than the diameter of the connecting rod 34, so that the connecting rod 34 can rotate radially in the rotating groove 33, and the connecting rod 34 can also move up and down in the rotating groove 33.

[0027] According to the above, when aquatic plants need to be placed in the breeding area at the bottom of the feed inlet 9, the electric push cylinder 5 will automatically push out the toothed plate 6, so that the toothed plate 6 is pushed onto the conveying movement path of the toothed ring 31. When the placement cylinder 3 drives the toothed ring 31 to continuously convey and move, the toothed ring 31 will mesh with the toothed plate 6. At this time, under the action of the meshing force, the toothed ring 31 will drive the rotating sleeve 32 and the connecting rod 34 to rotate together in the placement cylinder 3.

[0028] The feeding mechanism 7 includes a rotating seat 71 rotatably mounted at the bottom of the suspension rod 15, and a fixed sleeve 72 is fixed at the bottom of the rotating seat 71. When the connecting rod 34 rotates in the rotating groove 33, it will synchronously drive the rotating seat 71 and the fixed sleeve 72 to rotate radially around the suspension rod 15. The fixed sleeve 72 is internally threaded with a meshing block 73, which meshes with the threaded groove opened inside the fixed sleeve 72. A lifting rod 74 is fixed at the bottom of the meshing block 73, and a sealing block 75 is fixed at the bottom of the lifting rod 74. The sealing block 75 is conical, which facilitates the water plants on the sealing block 75 to slide down and discharge. During normal conveying, the sealing block 75 seals the bottom of the placement cylinder 3.

[0029] As described above, when material needs to be fed, the rotating seat 71 and the fixed sleeve 72 rotate. Under the action of the thread, the meshing block 73 and the lifting rod 74 move down in the fixed sleeve 72, causing the sealing block 75 to move down and open the placement cylinder 3, allowing the aquatic plants in the placement cylinder 3 to fall from the discharge port 9 into the aquaculture area. This achieves automated and precise operation of aquatic plant transportation and placement, greatly improving the efficiency of aquatic plant feeding and the standardization of aquaculture management. At the same time, by utilizing the three-dimensional operation advantages of the suspended conveyor, it does not occupy ground work space and reduces the frequency of manual contact with aquatic plants, which reduces labor costs and improves the uniformity of aquatic plant placement, which is conducive to improving the efficiency of large-scale aquaculture. Meanwhile, on the receiving frame 4 on the circulation conveyor inlet side of the suspended conveyor 1, there is another set of electric push cylinders 5 and toothed plates 6 with the opposite direction to the electric push cylinders 5 and toothed plates 6. This allows the placement cylinder 3 and toothed ring 31 to be driven to rotate in the opposite direction when they pass by after material feeding, thereby resetting the sealing block 75 and moving it up to seal it again for the next cycle of transportation.

[0030] To solve the technical problems of easy blockage and difficulty in stable material feeding during conveying, such as Figures 2-6 As shown, the following preferred technical solutions are provided: The upper surface of the gear ring 31 is fixed with a second protrusion 36, which is spherical. The bottom of the placement cylinder 3 is fixed with several second protrusions 36 in a ring, and a first protrusion 35 is set between two adjacent second protrusions 36. When the gear ring 31 and the rotating sleeve 32 rotate on the placement cylinder 3, the first protrusion 35 will continuously pass over the second protrusion 36.

[0031] A rubber sleeve 37 is fixed to the lower inner surface of the placement cylinder 3, and the bottom of the rubber sleeve 37 is fixed to the toothed ring 31. A telescopic column 30 is installed in the middle of the suspension rod 15. The telescopic column 30 consists of a column that extends and retracts vertically and an external spring. The rubber sleeve 37 is made of elastic and deformable rubber material, which can prevent aquatic plants from entering between the toothed ring 31 and the placement cylinder 3. When the first protrusion 35 continuously passes over the second protrusion 36, the placement cylinder 3 will have a continuous vibration effect through the telescopic column 30. Thus, when the placement cylinder 3 feeds aquatic plants, the vibration effect helps to speed up the feeding of aquatic plants and prevent aquatic plants from accumulating in the placement cylinder 3, thereby improving the stability of automatic feeding, ensuring the effect of shrimp and crab farming, and avoiding material blockage that affects the stability of the suspended conveyor.

[0032] To address the technical problem of aquatic plants accumulating during transport and ensuring uniform distribution, such as... Figures 2-7 As shown, the following preferred technical solutions are provided: The feeding mechanism 8 includes rotating gears 81 rotatably mounted on both sides of the receiving frame 4, and a fixed shaft 82 is fixed to the bottom of the rotating gears 81. A toothed plate 40 meshes with one side of the rotating gears 81, and the toothed plate 40 is fixed on the placement cylinder 3. The rotating gears 81 are arranged on both sides of the discharge port 9. When the suspended conveying placement cylinder 3 and the toothed plate 40 pass over the rotating gears 81, the toothed plate 40 will drive the rotating gears 81 and the fixed shaft 82 to rotate.

[0033] A reverse lead screw 83 is fixed to the bottom of the fixed shaft 82, and a limit plate 84 is fixed to both the upper and lower ends of the reverse lead screw 83. The reverse lead screw 83 and the limit plate 84 can rotate together with the rotating gear 81 and the fixed shaft 82.

[0034] The external thread of the reverse screw 83 is connected to a sliding sleeve 85, and a material-pulling plate 86 is fixed to the outer ring of the sliding sleeve 85. When the reverse screw 83 rotates, the thread structure allows the sliding sleeve 85 and the material-pulling plate 86 to move up and down and rotate on the reverse screw 83 at the same time. The limiting plate 84 can restrict the movement of the sliding sleeve 85. Thus, when the placement cylinder 3 is conveyed to the discharge port 9 for feeding, the material-pulling plate 86 can be used to disperse the falling aquatic plants, so that the coverage of the falling aquatic plants is more uniform, improving the effect of shrimp and crab farming. At the same time, the material-pulling plate 86 can also move the aquatic plants that have not fallen in the receiving frame 4 to fall, thereby avoiding the possibility of aquatic plants accumulating in the receiving frame 4 and avoiding the problem of aquatic plants interfering with the subsequent conveying of the placement cylinder 3, thus helping to ensure the stability of the suspended conveying.
