Description

Technical Field

[0001] This invention relates to the field of aquaculture machinery technology, specifically to a fermentation bed turning device for aquaculture. Background Technology

[0002] Currently, most livestock farming equipment is equipped with a slatted floor at the bottom to facilitate the discharge of animal manure into a fermentation tank beneath the equipment (such as chicken coops and duck cages). The bottom of the fermentation tank is usually filled with packing material (such as straw, rice husks, wheat bran, and other high-carbon materials used to adjust the carbon-nitrogen ratio and promote fermentation) to ferment together with the manure. After a period of time, the fermented organic fertilizer can be taken out and used.

[0003] For large-scale fermentation tanks, removing manure and adding packing materials is quite difficult. Simple mechanical aids such as manure scrapers are typically used to assist manual operation. These scrapers use a scraper that moves along the bottom of the fermentation tank to scrape out manure or help scrape packing materials into the tank. However, this method has low automation and still requires a significant amount of manual labor. In animal husbandry, animal manure continuously passes through a slatted floor into the fermentation tank. Current technology lacks equipment that can integrate the functions of a manure scraper with the mixing and turning of manure and packing materials. Therefore, it is necessary to improve existing technologies. Utility Model Content

[0004] This invention discloses a fermentation bed turning device for aquaculture, which aims to solve the problems in the prior art mentioned in the background section: 1. The existing equipment has a low degree of automation and a high amount of manual labor; 2. There is a lack of equipment that integrates turning and mixing of fermentation tanks with the function of a manure scraper.

[0005] To achieve the above objectives, the technical solution of this invention is as follows: A fermentation bed turning device for aquaculture includes a U-shaped fermentation tank with one open end and a device body disposed within the fermentation tank. The device body includes a support plate that moves back and forth along the fermentation tank via a linear drive mechanism. The front and rear surfaces of the support plate are respectively provided with a first set of turning mechanisms and a second set of turning mechanisms. The first set of turning mechanisms and the second set of turning mechanisms are respectively provided with plow plates and telescopic mechanisms. The plow plates on the front and rear sides are staggered. The height of the plow plates is adjusted by the telescopic mechanism. When the plow plates on the front and rear sides extend downward to the same depth from the bottom of the support plate, the plow plates on the front and rear sides are spliced ​​together to form a scraper structure. The plow plates on the front and rear sides face the front and rear sides of the fermentation tank, respectively.

[0006] Preferably, the front end of the fermentation tank is open, and grooves are provided on the top of both sides of the front end of the fermentation tank. A connecting beam is fixedly connected between the two grooves. The top of the connecting beam is flush with the top of the fermentation tank. Several evenly distributed pad beams are also fixedly provided on the top of the fermentation tank along the front-back direction. A breeding container for animals to live in is fixedly provided on the top of the pad beams. A manure slat is provided inside the breeding container and on top of the pad beams.

[0007] Preferably, the top end of the load-bearing plate is fixedly connected to the bottom end of the movable seat, and the front and rear surfaces of the lower part of the load-bearing plate are respectively provided with a first set of guiding mechanisms and a second set of guiding mechanisms. The first set of guiding mechanisms and the second set of guiding mechanisms each include several T-shaped grooves arranged side by side in the left-right direction. The T-shaped grooves penetrate the outer surface and bottom of the load-bearing plate, and the T-shaped grooves on the front and rear sides are staggered.

[0008] Preferably, the first and second sets of planing mechanisms have the same structure, both including a plow plate with a triangular cross-section. The tip of the plow plate faces away from the load-bearing plate. A connecting plate is fixedly provided on the back of the plow plate and inserted into the narrow end of the T-shaped groove. A vertical plate that slides with the wide end of the T-shaped groove is fixedly provided on the end of the connecting plate away from the plow plate. When the plow plates on the front and rear sides extend downward to the same depth from the bottom of the load-bearing plate, the vertical plates on the front and rear sides are spliced ​​together to form a scraper structure.

[0009] Preferably, the bottom of the upright plate is flush with the bottom of the plow plate. When the upright plates are spliced ​​together to form a scraper structure, the gap between the front and rear upright plates is 2-10mm.

[0010] Preferably, the telescopic mechanism includes electric cylinders located on the front and rear sides of the load-bearing plate. The fixed end of the electric cylinder is fixedly connected to the outer surface of the load-bearing plate, and the telescopic end extends vertically downward. A crossbar is fixedly connected to the top of the connecting plates located on the front and rear sides, respectively. The telescopic end is fixedly connected to the crossbar, and the crossbar slides in cooperation with the outer surface of the load-bearing plate. Driven by the electric cylinder, the first set of planing mechanisms and the second set of planing mechanisms move up and down along the T-shaped groove.

[0011] Preferably, it also includes a controller and a storage battery. The outer surface of the fermentation tank is provided with a control box, and the control box contains a controller and a storage battery that are electrically connected to each other. The controller is configured to control the operation of the electric cylinder and the geared motor.

[0012] This novel fermentation bed turning device for aquaculture has the following beneficial effects: This new invention enables automated turning and pushing of the fermentation bed at the bottom of the fermentation tank. At the same time, it integrates the scraper function of the manure scraper with the turning and mixing function, saving equipment costs and improving work efficiency. The turning and mixing can improve the fermentation effect, and the vertical plates combined into a scraper structure can scrape out the manure and scrape in the filler, greatly reducing the intensity of manual labor and the difficulty of the work.

[0023] The following is a detailed description of the embodiments of the present invention in a step-by-step manner. This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0024] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this invention.

[0025] Example 1: A fermentation bed turning device for aquaculture, such as Figure 1-9 As shown, the device includes a U-shaped fermentation tank 7 with one end open and a device body located inside the fermentation tank 7. The device body includes a support plate 10 that moves back and forth along the fermentation tank 7 via a linear drive mechanism. The front and rear surfaces of the support plate 10 are respectively provided with a first set of turning mechanisms and a second set of turning mechanisms. The first set of turning mechanisms and the second set of turning mechanisms are respectively provided with plow plates 14 and telescopic mechanisms. The plow plates 14 on the front and rear sides are staggered. The height of the plow plates 14 is adjusted by the telescopic mechanism. When the plow plates 14 on the front and rear sides extend downward to the same depth from the bottom of the support plate 10, the plow plates on the front and rear sides are spliced ​​together to form a scraper structure. The plow plates 14 on the front and rear sides face the front and rear sides of the fermentation tank, respectively.

[0026] In this embodiment, the plow plates 14 are staggered and face opposite directions. When the device body moves forward, it can turn over the packing material and manure at the bottom of the fermentation tank. The area between the front plow plates is turned over by the rear plow plate when the device body moves backward. This back-and-forth operation ensures thorough mixing of the manure and packing material. During the turning operation, when the front plow plates are working, the rear plow plates retract under the action of the telescopic mechanism; conversely, when the rear plow plates are working, the front plow plates retract. The telescopic mechanism adjusts the height of the plow plates. When both the front and rear plow plates extend a certain length, they connect to form a scraper structure, which helps to scrape the packing material at the front end of the fermentation tank into the fermentation tank or scrape out the organic fertilizer accumulated in the fermentation tank. The linear drive mechanism can be a device in the prior art capable of driving the load-bearing plate to move back and forth.

[0027] Example 2: like Figure 1 , 3 As shown in Figure 4, the front end of the fermentation tank 7 is open (for the inlet and outlet of organic fertilizer and filler). Grooves (not marked in the figure) are provided on the top of both sides of the front end of the fermentation tank 7. A connecting beam 8 is fixedly connected between the two grooves. The top of the connecting beam 8 is flush with the top of the fermentation tank 7. Several evenly distributed pad beams 3 (to provide support for the breeding container) are also fixedly provided on the top of the fermentation tank 7 along the front-back direction. A breeding container 1 for animals to live in is fixedly provided on the top of the pad beams 3. A manure slat board 2 is provided inside the breeding container 1 and located on top of the pad beams.

[0028] In this embodiment, animal feces enter the fermentation tank through the gaps between the slatted floor and the pad beam. The breeding container 1 can be an existing product depending on the type of animal.

[0029] Example 3: like Figure 2 As shown, the top end of the load-bearing plate 10 is fixedly connected to the bottom end of the movable seat 6. The front and rear surfaces of the lower part of the load-bearing plate 10 are respectively provided with a first set of guide mechanisms and a second set of guide mechanisms, such as... Figure 3 , 5 As shown in Figure 8, both the first and second guide mechanisms include several T-shaped grooves 18 arranged side by side in the left-right direction. The T-shaped grooves 18 penetrate the outer surface and bottom of the load-bearing plate 10, and the T-shaped grooves 18 on the front and rear sides are staggered.

[0030] like Figure 1-8 As shown, the first and second sets of planing mechanisms have the same structure, both including a plow plate 14 with a triangular cross-section. The tip of the plow plate 14 faces away from the support plate 10. A connecting plate 15 is fixedly provided on the back of the plow plate 14 and inserted into the narrow end of the T-shaped groove (i.e., the structure corresponding to the vertical part of the T). A vertical plate 16 is fixedly provided at the end of the connecting plate 15 away from the plow plate 14 and slides in cooperation with the wide end of the T-shaped groove 18 (i.e., the structure corresponding to the horizontal part of the T). When the plow plates 14 on the front and rear sides extend downward to the same depth from the bottom of the support plate, the vertical plates 16 on the front and rear sides are spliced ​​together to form a scraper structure.

[0031] In this embodiment, the plow plate can be formed by bending cold-rolled steel plate, and the bottom end of the plow plate has a cutting edge structure, which facilitates insertion into the filler and manure; when the plow plate moves, it separates the manure and filler, and turns and mixes them. When the front and rear upright plates are spliced ​​into a scraper structure, the organic fertilizer can be pushed out from the front end of the fermentation tank or the filler can be pushed back into the fermentation tank.

[0032] Example 4: like Figure 1-8 As shown, the bottom of the vertical plate 16 is flush with the bottom of the plow plate 14. When spliced ​​into a scraper structure, the vertical plates on the front and rear sides are fitted with a gap ranging from 2 to 10 mm. Such a small gap will not affect the scraper structure's function of pushing organic fertilizer and filler. At the same time, it replaces the integrated scraper of the traditional manure scraper, effectively integrating the plow plate's turning and mixing function with the scraper function of the manure scraper. That is, this new type can realize both the turning and mixing function and the scraper function. When using the turning and mixing function, the front and rear plow plates are used alternately. When using the scraper function, the front and rear vertical plates are extended downwards and spliced ​​into a scraper structure.

[0033] Example 5: like Figure 1-8As shown, the telescopic mechanism includes electric cylinders (first electric cylinder 11 and second electric cylinder 12) located on the front and rear sides of the load-bearing plate 10. The fixed end of the electric cylinder is fixedly connected to the outer surface of the load-bearing plate 10, and the telescopic end extends vertically downward. A crossbar 13 is fixedly connected to the top of the connecting plates 15 located on the front and rear sides, respectively. The telescopic end is fixedly connected to the crossbar 13, and the crossbar 13 slides with the outer surface of the load-bearing plate 10. Driven by the electric cylinder, the first set of planing mechanisms and the second set of planing mechanisms rise and fall along the T-shaped groove 18.

[0034] The plow plate and upright plate can be extended downwards by a set length as needed using an electric cylinder.

[0035] Example 6: like Figure 1-8 As shown, it also includes a controller and a storage battery (not shown in the figure). The outer surface of the fermentation tank is equipped with a control box, and the control box contains a controller and a storage battery that are electrically connected to each other. The controller is configured to control the operation of the electric cylinder and the geared motor.

[0036] In this embodiment, the controller can be a common device such as a PLC, control circuit board, or STM32. The STM32 can remotely control the electric cylinder via the ESP8266 Wi-Fi module. However, the electric cylinder must support wireless communication protocols (such as PWM, pulse signals, etc.) to receive signals. Figure 9 As shown, another common implementation is that the controller is connected to the control circuit of the electric cylinder via cable 20. The linear guide 17 can be selected as a guide rod structure, and the cable can be fixedly connected to slip rings 19 at equal intervals. The slip rings 19 slide with the guide rod to avoid the cable from getting tangled during the movement of the moving seat.
