Description

Technical Field

[0001] This utility model relates to an eel size sorting and diversion device. Background Technology

[0002] During the factory farming of eels, due to different growth rates, it is necessary to sort eels of different sizes after 2-3 months of farming. The sorted eels are then exported according to their size. For example, smaller eels are sent to special farming ponds, while larger eels are sent to the market for sale.

[0003] Currently, after eels are sorted by size, the selected eels are temporarily held in different collection tanks. They are then manually removed from these tanks and transferred to transport equipment. However, since many eel collection tanks are located in low-lying areas, manually removing the eels is not only inconvenient but also inefficient. Therefore, it is necessary to improve this technical method. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by providing a device for sorting and diverting eels by size.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an eel size sorting and diversion device, comprising multiple diversion cylinders corresponding to the positions of multiple parallel collection and holding tanks, the multiple diversion cylinders being located above and behind the multiple collection and holding tanks, and a conveying pipe for outputting eels being provided at the lower rear end of each collection and holding tank; a diversion input port being provided at the middle of the front end of each diversion cylinder, and a lifting frame being provided between each diversion cylinder and the corresponding collection and holding tank, the top of the lifting frame being open to facilitate receiving the eels output from the collection and holding tank, and a discharge port being provided at the rear end of the lifting frame; each lifting frame being driven vertically to rise and fall by a lifting mechanism, so that the lifting frame lifts the eels output from the collection and holding tank to the height of the diversion cylinder, the eels in the lifting frame being output from the discharge port and entering the diversion cylinder through the diversion input port, and a diversion output pipe being connected to the bottom of the diversion cylinder.

[0006] Furthermore, the bottom of the diversion cylinder is provided with two diversion grooves symmetrically distributed on the left and right. The cross-section of the diversion grooves is arc-shaped, and the centerline of the diversion inlet coincides with the axis of symmetry of the two diversion grooves.

[0007] Furthermore, each diversion channel is inclined with a high front end and a low rear end, and each diversion channel has a vertically penetrating diversion output port at the bottom of its rear end, which is connected to a diversion output pipe.

[0008] Furthermore, the top of the diversion cylinder is connected to two water inlet pipes distributed on the left and right, and the two water inlet pipes correspond to the positions of the two diversion channels respectively.

[0009] Furthermore, the lifting mechanism includes a pair of lifting guide rails disposed on the front side of the diverter. The pair of lifting guide rails are symmetrically distributed on the left and right. A lifting rope is disposed between the pair of lifting guide rails. The upper end of the lifting rope is connected to the winch, and the lower end of the lifting rope is connected to the lifting frame. The lifting frame and the pair of lifting guide rails slide vertically together. When the winch winds up the lifting rope, the lifting rope pulls the lifting frame to move upward along the pair of lifting guide rails.

[0010] Furthermore, the cross-section of the lifting guide rail is groove-shaped, and the grooves of a pair of lifting guide rails are arranged facing each other; a pair of sliding wheels are installed on the left and right ends of the rear side of the lifting frame, and each pair of sliding wheels is distributed vertically, with a pair of sliding wheels extending into the lifting guide rail located on the same side and rolling in cooperation with the lifting guide rail.

The lifting ring is connected to the lower end of the lifting rope.

[0012] Furthermore, a guide plate is provided inside the diversion inlet along the front-to-back direction. The guide plate is inclined with a higher front end and a lower rear end. Vertical side plates are fixed at both ends of the guide plate. A U-shaped vertical slot is provided at the lower middle of the rear side of the lifting frame. The vertical slot is located at the lower edge of the discharge port. A discharge shield plate for blocking the discharge port is inserted into the vertical slot.

[0013] Furthermore, the bottom of the lifting frame has a mesh structure and is inclined with a higher front end and a lower rear end.

[0014] Furthermore, it also includes a drainage trough disposed between multiple collection and holding tanks and multiple diversion cylinders.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-7As shown, this utility model discloses an eel size selection and diversion device, comprising multiple collection and holding tanks 1 arranged side by side in a left-right direction. The collection and holding tanks 1 are connected to an eel size selection device (not shown in the figure). Each collection and holding tank 1 holds one type of eel after size selection, which is existing technology. Specifically, the diversion device includes multiple diversion cylinders 2 corresponding to the positions of the multiple side-by-side collection and holding tanks 1. The number of diversion cylinders 2 corresponds to the number of collection and holding tanks 1. The multiple diversion cylinders 2 are located above and behind the multiple collection and holding tanks 1. Each collection and holding tank 1 has a conveying pipe 3 for outputting eels at its lower rear end. A diversion input port 4 is provided at the middle of the front end of each diversion cylinder 2. A cuboid lifting frame 5 is provided between each diversion cylinder 2 and the corresponding collection and holding tank 1. The top of the lifting frame 5 is open to facilitate the receiving of eels output from the conveying pipe 3 of the corresponding collection holding tank 1. The rear end of the lifting frame 5 is provided with a discharge port 6. Each lifting frame 5 is driven by a lifting mechanism to move vertically up and down. The lifting mechanism lifts the eels output from the collection holding tank 1 to the height of the diversion cylinder 2 through the lifting frame 5. The eels in the lifting frame 5 are output from the discharge port 6 and enter the diversion cylinder 2 through the diversion input port 4. The bottom of the diversion cylinder 2 is connected to the diversion output pipe 7. The eels in the diversion cylinder 2 are output through the diversion output pipe 3. The relevant transfer equipment is set below the diversion output pipe to facilitate the receiving of the diverted eels. The eels are then transferred and output through the transfer equipment. The whole process does not require manual removal of the eels. The operation is simple and convenient, and effectively improves work efficiency.

[0026] In this embodiment, the inner bottom of the diversion cylinder 2 is provided with two symmetrically distributed diversion channels 8, one on the left and one on the right. The cross-section of the diversion channel 8 is arc-shaped, and the centerline of the diversion inlet 4 coincides with the axis of symmetry of the two diversion channels 8. By providing two diversion channels inside the diversion cylinder, the eels entering from the diversion inlet can fall into the two diversion channels, achieving simple left-right diversion and avoiding them all piling up together.

[0027] In this embodiment, each diversion channel 8 is inclined with a higher front end and a lower rear end. Each diversion channel 8 has a vertically penetrating diversion outlet at its rear bottom, which is connected to a diversion outlet pipe 7. That is, each diversion cylinder 2 is connected to two diversion outlet pipes 7. Designing the bottom of the diversion channel to be inclined facilitates better backward flow of the eel, allowing it to pass through the diversion outlet and be discharged.

[0028] In this embodiment, the top of the diversion cylinder 2 is connected to two water inlet pipes 9 distributed on the left and right. The two water inlet pipes 9 correspond to the positions of the two diversion channels 8 respectively, and the two water inlet pipes 9 are used to feed water into the two diversion channels 8 respectively.

[0029] In this embodiment, the lifting mechanism includes a pair of lifting guide rails 10 disposed on the front side of the diverter 2. The pair of lifting guide rails 10 are symmetrically distributed on the left and right and located on the rear side of the lifting frame 5. A lifting rope 11 is disposed between the pair of lifting guide rails 10. The upper end of the lifting rope 11 is connected to the winch 12, and the lower end of the lifting rope 11 is connected to the lifting frame 5. The lifting frame 5 and the pair of lifting guide rails 10 slide vertically. When the winch 12 winds up the lifting rope 11, the lifting rope 11 pulls the lifting frame 5 to move upward along the pair of lifting guide rails 10.

[0030] In this embodiment, the lifting guide rail 10 has a groove-shaped cross-section, and the grooves of a pair of lifting guide rails 10 are arranged facing each other. A pair of sliding wheels 13 are installed at both the left and right ends of the rear side of the lifting frame 5. Each pair of sliding wheels 13 is distributed vertically, and each pair of sliding wheels 13 extends into the lifting guide rail 10 located on the same side and rolls in cooperation with the lifting guide rail 10. When the lifting rope 11 pulls the lifting frame 5 upwards, the sliding wheels 13 roll along the lifting guide rail 10. The cooperation between the groove-shaped lifting guide rail and the sliding wheels improves the stability of the lifting frame's lifting.

[0031] In this embodiment, a lifting connecting rod 14 is fixed to the top opening of the lifting frame 5. The lifting connecting rod 14 is located in the middle and rear part of the lifting frame 5, and a lifting ring 15 is provided at the top of the lifting connecting rod 14. The lifting ring 15 is connected to the lower end of the lifting rope 11. Since the lifting guide rail is located on the rear side of the lifting frame, connecting the lifting rope to the lifting connecting rod located in the rear part of the lifting frame at this time helps to achieve better lifting.

[0032] In this embodiment, in order to facilitate the eels output from the discharge port to pass through the diversion inlet better, a guide plate 16 is provided in the diversion inlet 4 along the front-to-back direction. The guide plate 16 is inclined with a high front end and a low rear end, and vertical side plates 17 are fixed at both the left and right ends of the guide plate 16.

[0033] In this embodiment, a U-shaped vertical slot 18 is provided at the lower center of the rear side of the lifting frame 5. The vertical slot 18 is located at the lower edge of the discharge port 6, and a discharge shield 19 for blocking the discharge port 6 is inserted into the vertical slot 18. During the upward lifting of the lifting frame 5, the discharge shield 19 is inserted into the vertical slot 18 to block the discharge port 6. When the lifting frame 5 moves upward to the point where the discharge port 6 corresponds to the position of the diversion inlet 4, the discharge shield 19 can be manually pulled out upward. At this time, the discharge port is in the open state, and the eels in the lifting frame are output from the discharge port and enter the diversion cylinder along the guide plate.

[0034] In this embodiment, the bottom of the lifting frame 5 has a mesh structure. When the eels and water in the temporary holding tank 1 are collected and output to the lifting frame 5 through the conveying pipe, the water passes through the bottom of the lifting frame and is discharged. That is, the lifting frame only moves the eels upward, while the water is discharged, reducing the weight of the lifting.

[0035] In this embodiment, the bottom of the lifting frame 5 is inclined with a higher front end and a lower rear end, so that the eel can move towards the discharge port more easily.

[0036] In this embodiment, the delivery pipe is a flexible hose, and a control valve may be installed on the delivery pipe.

[0037] In this embodiment, a drainage trough 20 is also provided between multiple collection and holding tanks 1 and multiple diversion cylinders 2. The drainage trough extends in the left and right direction. The drainage trough 20 is located below the collection and holding tanks 1 and corresponds to the position of multiple lifting frames 5, so as to facilitate the collection of water discharged from the lifting frames 5.

[0038] Specific implementation process:

[0039] Initially, the lifting frame 5 is located inside the drainage trough 20, with its top opening below the conveying pipe 3 of the collection holding tank 1. Multiple collection holding tanks 1 are connected to an eel size selection device, each holding one type of eel after size selection. When it is necessary to divert the eels in the collection holding tank 1, the eels and water in the collection holding tank 1 are output to the lifting frame 5 through the conveying pipe 3, and the water passes through the bottom of the lifting frame 5 into the drainage trough 20. Then, the winch 12 winds up the lifting rope 11, which pulls the lifting frame 5 upward, causing the eels to move upward along a pair of lifting guide rails 10. When the discharge port 6 of the lifting frame 5 moves to connect with the front end of the guide plate 16 in the diversion input port 4, the winch 12 stops, and the discharge baffle 19 is manually pulled upward. The eels in the lifting frame 5 pass through the discharge port 6 and enter the separation trough 8 of the diversion cylinder 2 along the guide plate 16, and then are output along the diversion output pipe 7.
