Description

Technical Field

[0001] The utility model relates to the technical field of lobster farming, in particular to a fry releasing device for crayfish in paddy fields. Background Art

[0002] Crayfish in paddy fields are very popular among consumers for their green and healthy characteristics. The cultivation of crayfish in paddy fields requires putting fry and bait into the water channels of the paddy fields, and the release of fry is an important link.

[0003] Most fry releasing devices load crayfish into a net frame, and then workers carry the net frame to the edge of the paddy field and directly pour the crayfish in the net frame into the paddy field. However, during the fry releasing process, the crayfish in the net frame are concentrated and all poured into the paddy field at one time, which is likely to cause damage to the crayfish and affect the survival rate in the later stage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fry releasing device for crayfish in paddy fields to solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fry releasing device for crayfish in paddy fields includes a net frame and two handles symmetrically arranged outside the net frame. A groove is opened at the lower end of the net frame. One side of the inner top surface of the groove is provided with a fixing plate. The lower end of the outer side of the fixing plate is hinged with a bottom plate. The upper end of the outer side of the fixing plate is hinged with a support plate. A plurality of limiting grooves matching with the support plate are opened on the bottom plate. The other side of the inner top surface of the groove is provided with a constraint component for clamping the bottom plate.

[0007] As a further description of the above technical scheme:

[0008] The constraint component includes a deflecting plate rotatably arranged on the inner top surface of the groove and a clamping bar arranged at the lower end of the outer side of the deflecting plate. A rectangular groove matching with the deflecting plate is opened on the bottom plate, and a clamping groove matching with the clamping bar is opened on the inner wall of the rectangular groove.

[0009] As a further description of the above technical scheme:

[0010] The sides of the net frame are all inclined planes with the same slope. The size of the lower end surface of the net frame is smaller than that of the upper end surface. A reinforcing frame opening is arranged at the upper end of the net frame.

[0011] As a further description of the above technical scheme:

[0012] The lower end surfaces of the net frame and the bottom plate are both serrated.

[0013] As a further description of the above technical scheme:

[0014] The surface of the reinforcing frame opening is smooth.

[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, by providing a groove, a fixing plate, a bottom plate, a support plate and a limiting groove, the net frame can be inclined and supported by the support plate, which is convenient for crayfish to climb outwards, effectively avoiding the concentration of crayfish in the net frame and dumping them at one time, thereby ensuring the survival rate of crayfish in the later stage;

[0017] In the present utility model, by providing a deflecting plate, a rectangular groove, a clamping strip and a clamping groove, the effect of limiting and fixing the bottom plate is achieved, avoiding the bottom plate being in a movable state in the natural state, and the bottom plate is prone to shaking when the staff carry the net frame.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figures 1-3As shown in the figure, a crayfish seedling releasing device for paddy fields includes a net frame 1 and two handles 3 symmetrically arranged outside the net frame 1. A groove 4 is opened at the lower end of the net frame 1. On one side of the inner top surface of the groove 4, a fixing plate 5 is provided. At the lower end of the outer side of the fixing plate 5, a bottom plate 6 is hinged. At the upper end of the outer side of the fixing plate 5, a support plate 7 is hinged. A plurality of limiting grooves 8 matching with the support plate 7 are opened on the bottom plate 6. On the other side of the inner top surface of the groove 4, a constraint component is provided for clamping the bottom plate 6. When releasing seedlings, the staff places the net frame 1 beside the water of the paddy field, then stretches one foot into the groove 4 to step on the bottom plate 6, and then holds one of the handles 3 with one hand and pulls it upward, making the net frame 1 gradually tilt. During this process, through the mutual cooperation of the support plate 7 and the limiting grooves 8, the effect of supporting the net frame 1 is achieved. At this time, the crayfish in the net frame 1 gradually climb outwards and enter the paddy field, realizing the effect of slowly releasing the crayfish into the paddy field. By continuously increasing the tilt angle of the net frame 1, most of the crayfish in the net frame 1 can naturally climb out. Subsequently, the small part of the remaining crayfish in the net frame 1 can be slowly poured into the paddy field, avoiding directly flipping and tilting the net frame 1 to pour all the crayfish into the paddy field at once, which is likely to cause damage to the crayfish and affect the survival rate.

[0024] Furthermore, the constraint component includes a deflecting plate 9 rotatably arranged on the inner top surface of the groove 4 and a clamping bar 10 arranged at the lower end of the outer side of the deflecting plate 9. A rectangular groove 11 matching with the deflecting plate 9 is opened on the bottom plate 6, and a clamping groove 12 matching with the clamping bar 10 is opened on the inner wall of the rectangular groove 11. When in use, when the net frame 1 is placed horizontally, the deflecting plate 9 is in a vertical state under the action of gravity, its lower end is located in the rectangular groove 11, and the clamping bar 10 is stuck in the clamping groove 12, effectively restricting the natural deflection and shaking of the bottom plate 6. When releasing seedlings, when the staff stretches one foot into the groove 4, the tip of the toe will squeeze the deflecting plate 9 to make it deflect, further causing the clamping bar 10 to disengage from the clamping groove 12, and further causing the deflecting plate 9 to deflect out of the rectangular groove 11. At this time, when the staff steps on the bottom plate 6, the net frame 1 can be deflected to make it tilt.

[0025] Furthermore, the sides of the net frame 1 are all inclined planes with the same slope. The size of the lower end surface of the net frame 1 is smaller than that of the upper end surface. A reinforcing frame opening 2 is provided at the upper end of the net frame 1, so that the lower end of the net frame 1 can be put into the upper end of the net frame 1, which is convenient for stacking and placing the net frame 1.

[0026] Furthermore, the lower end surfaces of both the net frame 1 and the bottom plate 6 are serrated, effectively ensuring the stability of the net frame 1 placed on the ground.

[0027] Furthermore, the surface of the reinforcing frame opening 2 is smooth, effectively preventing the crayfish from climbing outwards when the net frame 1 is in a horizontal state.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
