[0026] The utility model is described in detail below in conjunction with the accompanying drawings.
[0027] See also Figure 1-2 The present embodiment provides a shrimp collecting device for shrimp farming, which includes a shrimp receiving barrel 1, a shrimp collecting net pipe 2 fixedly connected to a side wall corresponding to the shrimp receiving barrel 1, a sonar transformer 3 arranged on the shrimp collecting net pipe 2, a shrimp screening structure, a shrimp baffle plate 11, and two shrimp cages 12.
[0028] The shrimp receiving barrel 1 has an open structure at the top and bottom, and the shrimp receiving barrel 1 is divided into a shrimp screening space and a shrimp collecting space by a partition. The shrimp collecting net tube 2 is arranged with its end facing away from the shrimp receiving barrel 1 and tilted upward, and the shrimp collecting net tube 2 is placed at the water outlet of the shrimp breeding pond. The shrimp outlet of the shrimp collecting net tube 2 is connected to the shrimp screening space, and a sponge layer is laid on the inner wall of the shrimp collecting net tube 2, and the sponge layer is used for buffering to reduce damage to the shrimp when the shrimp is transported along the shrimp collecting net tube 2 in a directional manner.
[0029] The shrimp collecting net tube 2 is composed of a telescopic ring 21 and a shrimp collecting net 22. The shrimp collecting net 22 is covered and fixed on the telescopic ring 21, and the telescopic ring 21 is a spiral structure. The sonar transformer 3 is fixedly installed at the shrimp inlet of the shrimp collecting net tube 2 through a bracket. The sonar transformer 3 emits sonar audio to lure shrimps to move to the shrimp inlet of the shrimp collecting net tube 2, and cooperates with the water flow to cause the shrimps to be transported along the shrimp collecting net tube 2 to enter the shrimp receiving barrel 1, thereby reducing the stress response of the shrimps.
[0030] The shrimp screening structure is located in the shrimp screening space, and the shrimp screening structure includes a base plate I4 and a base plate II5 located above the partition, a crank 6 rotatably connected to the base plate I4, a vertical rod 7 rotatably connected to the base plate II5, a turntable I8 installed in the partition, a turntable II9 and a gear 10. The crank 6 is vertically fixed at the center of the turntable I8, and the vertical rod 7 is vertically fixed at the center of the turntable II9.
[0031] The upper surfaces of the turntable I8, turntable II9 and gear 10 are flush, wherein the gear 10 is meshed between the turntable I8 and turntable II9, and an installation cavity is provided on the partition, through which the turntable I8, turntable II9 and gear 10 are installed. It should be noted that in order to facilitate the shrimp to smoothly fall into the corresponding shrimp cage 12 through the turntable I8 and turntable II9 for collection, the part of the installation cavity used to accommodate the turntable I8 and turntable II9 is through the partition, and the part of the installation cavity used to accommodate the gear 10 is opened on the partition board surface, that is, a non-through design, so that the partition can support the gear 10, and the gear 10 is installed in the partition through the axle rotation. Hole I is provided through the turntable I8, and hole II is provided through the turntable II9. Hole I and hole II are both used to pass shrimp, and the aperture of hole I is smaller than the aperture of hole II.
[0032] The base plate I4 and the base plate II5 are horizontally covered at the top of the prawn receiving barrel 1, the crank 6 is perpendicular to the base plate I4, and the vertical rod 7 is perpendicular to the base plate II5. Since the turntable I8 and the turntable II9 are not subjected to supporting force, the crank 6 is fixed with a limit piece I in contact with the top surface of the base plate I4, and the vertical rod 7 is fixed with a limit piece II in contact with the top surface of the base plate II5. Based on the above arrangement, the crank 6 is prevented from coming out of the base plate I4, and the vertical rod 7 and the base plate II5 are prevented from coming out, thereby ensuring the stability of the meshing transmission between the turntable I8, the turntable II9 and the gear 10. The shrimp cage 12 is located in the shrimp receiving space, one of the shrimp cages 12 is located below the turntable I8, and the remaining shrimp cage 12 is located below the turntable II9.
[0033] The shrimp baffle plate 11 is vertically placed in the shrimp screening space, and a slot for passing shrimps is provided at the position of the shrimp baffle plate 11 facing the gear 10. The shrimp baffle plate 11 is fixedly mounted on the shrimp receiving barrel 1, and the shrimp baffle plate 11 is located between the base plate I4 and the base plate II5, and the bottom of the shrimp baffle plate 11 is arranged close to the partition. In this embodiment, the shrimp screening space is divided into two based on the shrimp baffle plate 11, so that the shrimp classification is carried out in an orderly manner.
[0034] The shrimp screening structure of this embodiment has the following working process: the crank 6 is manually operated to drive the turntable I8 to rotate. At this time, the turntable II9 also rotates under the meshing transmission of the gear 10. After the shrimps enter the shrimp receiving barrel 1 along the shrimp collecting net tube 2, they first fall to the turntable I8. The shrimps smaller than or equal to the size of the hole I pass through and fall into the corresponding shrimp cage 12, while the larger shrimps are intercepted and pass through the slots on the shrimp baffle plate 11 under the action of centrifugation, enter the turntable II9 and fall into the corresponding shrimp cage 12 along the hole II, thereby achieving the purpose of shrimp screening and classification. It should be noted that in other embodiments, the rotating force required for shrimp screening and classification can also be applied by a rotating motor to drive the crank 6, which will not be repeated here.
[0035] In summary, the shrimp collecting device of this embodiment has the following advantages: it uses sonar audio to lure shrimps, and cooperates with water flow to force shrimps into the collection area, thereby reducing the stress response of shrimps and reducing the damage caused to shrimps during the shrimp collecting process. In addition, the shrimps can be screened and classified while being collected, reducing the manual input required for subsequent manual sorting.
[0036] The naming of each component involved is based on the functions described in the specification, and is not limited to the specific nouns used in the utility model. Those skilled in the art may also choose other nouns to describe the names of the components of the utility model.
