Description

Technical Field

[0001] This invention belongs to the field of crayfish farming technology, specifically a breeding box for indoor crayfish farming. Background Technology

[0002] With the crayfish market remaining booming, indoor crayfish farming is gradually becoming a popular farming model due to its advantages such as being unrestricted by seasons and regions and having a controllable farming environment. As a key piece of equipment in indoor crayfish farming, the performance of the farming box directly affects the farming results.

[0003] Because indoor breeding sites vary in spatial layout, shape, and structure, existing breeding boxes usually need to be customized according to the size of the site. This not only leads to a significant increase in procurement costs but also results in a long customization cycle. If the breeding site changes, the customized breeding boxes may not be able to adapt to the new site, causing a waste of resources.

[0004] On the other hand, during the crayfish farming process, their excrement will continuously pollute the filter cotton in the breeding tank. Most existing breeding tanks rely on manual regular inspection and cleaning of the filter cotton, which requires farmers to spend a lot of time and energy. Manual cleaning is not only inefficient, but frequent manual cleaning will also interfere with the normal growth environment of crayfish, affecting their growth rate and quality.

[0005] Therefore, the present invention provides a breeding box for indoor crayfish farming. Summary of the Invention

[0045] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0046] like Figures 1 to 9 As shown, the crayfish indoor aquaculture box of the present invention includes a housing, a water injection mechanism, a drainage mechanism, a filtration mechanism, and a slag removal mechanism.

[0047] The housing includes a middle section plate 2, an end plate 1, and a sealing gasket 3. Both the middle section plate 2 and the end plate 1 are made of plastic, and the sealing gasket 3 is a common sealing rubber. The middle section plate 2 is a U-shaped plate, and the two ends of the middle section plate 2 are closed by the two end plates 1, thereby providing a breeding space for crayfish.

[0048] Both the middle section plate 2 and the end plate 1 have ear plates for bolt installation on their side walls. When two middle section plates 2 are assembled, the connection position is sealed by the sealing gasket 3. When it is necessary to increase the breeding space, multiple middle section plates 2 can be assembled.

[0049] When the end panel 1 and the middle section panel 2 are assembled, the connection position is sealed by the sealing gasket 3 to prevent water leakage. The middle section panel 2 can be assembled according to needs, which can be adapted to different room sizes when raising livestock indoors.

[0050] The water injection mechanism is used to inject water into the middle section plate 2. The drainage mechanism includes a mounting box 6 and a drainage grate 11. The drainage grate 11 is set on the side wall of the middle section plate 2. After the water injection mechanism injects water into the middle section plate 2, the liquid level rises to the drainage grate 11 and is discharged through the drainage grate 11.

[0051] The mounting box 6 is fixedly installed on the outer wall of the middle section plate 2 and communicates with the inner cavity of the middle section plate 2 through the drainage grate 11. The bottom of the mounting box 6 is provided with a conduit for connecting to an external water resource storage chamber to recover the water discharged from the drainage grate 11.

[0052] The filtration mechanism includes a control roller 20 and a filter cylinder 12. The filter cylinder 12 is fitted onto the outer wall of the control roller 20. The axial end of the control roller 20 is rotatably connected to the inner wall of the mounting box 6. The control roller 20 provides installation and support for the filter cylinder 12. In this embodiment, the filter cylinder 12 is made of a sponge material that is elastic and has a filtering effect. The water discharged from the drain grate 11 is filtered through the filter cylinder 12 and then recycled for reuse after treatment.

[0053] The slag discharge mechanism includes a slag discharge cylinder 14 and a feeding auger 21. The slag discharge cylinder 14 is fixedly installed on the inner wall of the mounting box 6. The feeding auger 21 is rotatably installed inside the slag discharge cylinder 14, and its outer wall is in contact with the outer wall of the filter cylinder 12. As the filter cylinder 12 filters, the dirt (such as lobster excrement) in the water flow in the middle plate 2 adheres to the outer wall of the filter cylinder 12. At this time, by rotating the feeding auger 21, the outer wall of the filter cylinder 12 is scraped and the scraped dirt is transported, thereby maintaining the filtration efficiency of the filter cylinder 12, maintaining the breeding environment, and improving the survival rate.

[0054] The water injection mechanism includes a water injection cylinder 4, a heating element 9, an adsorption cylinder 10, and a buffer cylinder 8. One end of the water injection cylinder 4 is connected to an external water source, and the other end of the water injection cylinder 4 is fixedly connected to the outer wall of the middle section plate 2, thereby injecting clean water into the interior of the middle section plate 2.

[0055] like Figure 3 As shown, the heating element 9, the adsorption cylinder 10, and the buffer cylinder 8 are all fixedly installed inside the water injection cylinder 4.

[0056] The heating element 9 is used to heat the liquid passing through the water injection cylinder 4. The heating element 9 is a resistance heating wire, which is spirally distributed inside the water injection cylinder 4 to maintain the temperature of the water inside the middle section plate 2 by heating.

[0057] The adsorption cylinder 10 is used to adsorb and filter the liquid passing through the water injection cylinder 4. The inside of the adsorption cylinder 10 is common activated carbon, which is used to adsorb dirt in the water passing through the water injection cylinder 4 and maintain the water quality.

[0058] The buffer cylinder 8 is made of sponge material, which plays a buffering role when water is injected into the water injection cylinder 4, and prevents the lobster from being damaged by the impact of the water flow after the lobster hatches.

[0059] A constricted cylinder 13 is fixedly installed at one axial end of the slag discharge cylinder 14, and the other end of the constricted cylinder 13 extends to the outer wall of the mounting box 6 and is fixedly installed with a discharge pipe 15. The constricted cylinder 13 is frustum-shaped.

[0060] The inner wall of the mounting box 6 is rotatably mounted with a conveying shaft 16, and the conveying auger 21 is fixedly connected to the outer wall of the conveying shaft 16. When the conveying shaft 16 rotates, it drives the conveying auger 21 to rotate, thereby scraping the filter cylinder 12.

[0061] The inner walls of the slag discharge cylinder 14, the constriction cylinder 13, and the discharge pipe 15 are all in contact with the outer wall of the conveying auger 21. As the conveying shaft 16 rotates, solid materials are conveyed to the discharge pipe 15 and discharged through the conveying auger 21. Liquid materials flow back into the installation box 6 under gravity when they move to the inclined surface of the constriction cylinder 13.

[0062] A guide plate 5 is fixedly installed on the outer wall of the middle section plate 2. The guide plate 5 is located directly below the discharge pipe 15. The solid material discharged from the discharge pipe 15 falls above the guide plate 5 to facilitate the discharge of dirt.

[0063] In a preferred embodiment of the present invention, a first mounting bracket 27 is fixedly mounted on the outer wall of the mounting box 6, and a first transmission disc 28 is rotatably mounted on the inner wall of the first mounting bracket 27. The first mounting bracket 27 provides mounting and support for the first transmission disc 28.

[0064] The axial end of the first transmission disc 28 is fixedly connected to the axial end of the conveying shaft 16. Rotating the first transmission disc 28 drives the conveying shaft 16 to rotate, thereby controlling the rotation of the conveying auger 21.

[0065] A second mounting bracket 17 is fixedly mounted on the outer wall of the mounting box 6, and a second transmission disc 32 is rotatably mounted on the inner wall of the second mounting bracket 17. The second mounting bracket 17 provides installation and support for the second transmission disc 32.

[0066] A control gear 18 is fixedly installed on the inner wall of the second transmission disk 32, and a transmission gear 19 that meshes with the control gear 18 is fixedly installed on the radial outer wall of the control roller 20. When the second transmission disk 32 is rotated, the transmission gear 19 is driven to rotate by the control gear 18, which in turn drives the control roller 20 to rotate, thereby changing the filter surface of the filter cylinder 12.

[0067] A drive motor 7 is fixedly mounted on the outer wall of the second mounting bracket 17. The output shaft of the drive motor 7 is fixedly mounted with a first transmission wheel 30 and a second transmission wheel 34. The drive motor 7 is a common servo motor with a steering adjustment function, used to control the rotation of the first transmission wheel 30 and the second transmission wheel 34.

[0068] The inner wall of the first transmission disc 28 is fixedly installed with a first ratchet 31, and the outer wall of the first transmission wheel 30 is elastically installed with a first ratchet bar 29 that cooperates with the first ratchet 31. Through the cooperation of the first ratchet 31 and the first ratchet bar 29, the unidirectional transmission between the first transmission wheel 30 and the first transmission disc 28 is realized.

[0069] The inner wall of the second transmission disc 32 is fixedly installed with a second ratchet 33, and the outer wall of the second transmission wheel 34 is elastically installed with a second ratchet bar 35 that cooperates with the second ratchet 33. Through the cooperation of the second ratchet 33 and the second ratchet bar 35, the unidirectional transmission between the second transmission wheel 34 and the second transmission disc 32 is realized.

[0070] When the output shaft of the drive motor 7 rotates in the forward direction, it drives the first transmission disk 28 to rotate, which in turn drives the material conveying shaft 16 to rotate. When the output shaft of the drive motor 7 rotates in the reverse direction, it drives the second transmission disk 32 to rotate, which in turn drives the control roller 20 to rotate.

[0071] In a preferred embodiment of the present invention, a control plug 37 is slidably installed in the inner cavity of the control roller 20, and a connecting pipe 36 is fixedly installed on the outer wall of the control roller 20. The inner cavity of the connecting pipe 36 is unidirectionally open, and a one-way valve (not shown in the figure) communicating with the external air of the mounting box 6 is provided on the outer wall of the control roller 20.

[0072] An exhaust pipe 24 is fixedly installed at the other end of the connecting pipe 36. An exhaust hole 26 is provided on the outer wall of the exhaust pipe 24. External air is drawn into the inner cavity of the control roller 20 by the reciprocating sliding control plug 37 and then discharged through the exhaust hole 26, blowing the filter cartridge 12 from the inside out, so as to facilitate the removal of dirt and improve the cleaning efficiency of the filter cartridge 12.

[0073] like Figure 5-9 As shown, a perforated plate 41 is fixedly installed on the inner wall of the connecting pipe 36. A conical plug 40 is connected to the bottom surface of the perforated plate 41 through an elastic element. The perforated plate 41 is connected to the conical plug 40 through a spring. The elastic force of the spring pushes the conical plug 40 to slide downward in real time.

[0074] A partition plate 42 is fixedly installed on the inner wall of the connecting pipe 36, and a through hole for the conical plug 40 to be inserted is fixedly installed on the outer wall of the partition plate 42. Through the cooperation of the partition plate 42 and the conical plug 40, the unidirectional flow of the inner cavity of the connecting pipe 36 is realized, while preventing the liquid inside the filter cartridge 12 from entering the interior of the connecting pipe 36.

[0075] An installation sleeve 38 is fixedly installed on the outer wall of the control plug 37, and a sliding rod 39 is fixedly installed on the inner wall of the installation box 6. One end of the sliding rod 39 extends into the inner cavity of the installation sleeve 38 and is slidably connected to the inner wall of the installation sleeve 38. By sliding the installation sleeve 38 and the sliding rod 39, the sliding trajectory of the control plug 37 is limited, thereby improving the stability of the sliding of the control plug 37.

[0076] A control rod 25 is fixedly installed on the outer wall of the control plug 37, and the control rod 25 and the control plug 37 have the same movement state.

[0077] A connecting frame 23 is fixedly installed on the outer wall of the mounting box 6. A transmission cylinder 22 is rotatably installed on the inner wall of the connecting frame 23. A control rod 25 extends into the inner cavity of the transmission cylinder 22 and is connected by a reciprocating thread. Rotating the transmission cylinder 22 drives the control rod 25 and the control plug 37 to slide back and forth, thereby realizing the backflushing of the filter cylinder 12.

[0078] The conveying shaft 16 controls the rotation of the transmission cylinder 22 through a transmission component. In this embodiment, the transmission component is a common belt and pulley. The conveying shaft 16 controls the rotation of the transmission cylinder 22 through the cooperation of the belt and pulley, thereby simultaneously scraping the outer wall of the filter cylinder 12 during backwashing, further improving the cleaning effect.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
