Description

Technical Field

[0001] This invention relates to the field of earthworm farming technology, specifically to an earthworm farming device for the degradation of cow dung. Background Technology

[0002] In the beef cattle farming industry, the treatment and resource utilization of cow manure is a key issue restricting the industry's sustainable development. Earthworm farming technology, due to its ability to convert cow manure into high-value-added earthworm castings and earthworm protein, is gradually becoming an important technological approach for cow manure treatment. However, existing earthworm farming equipment still faces certain technical bottlenecks in its engineering application.

[0003] Existing earthworm farming equipment generally adopts a single-tank integrated structure, where the drive mechanism needs to vibrate the entire farming substrate to achieve the feeding function. This design has technical drawbacks: First, energy loss is positively correlated with material quality; as the processing scale increases, the drive energy consumption increases exponentially, resulting in high operating costs for large-scale farms. Second, the feeding component relies on an independent power source, requiring additional motors or hydraulic systems, further increasing energy consumption.

[0004] In earthworm farming, the feeding process is a crucial step affecting farming efficiency and product quality. Traditional equipment poses a significant risk of earthworms being accidentally discharged during feeding, which leads to a series of problems: First, the accidentally discharged earthworms are expelled from the equipment along with the earthworm castings, wasting earthworm resources and reducing earthworm yield; second, the accidental discharge also increases the cost and time of manual sorting, reducing overall farming efficiency.

[0005] Therefore, it is necessary to provide an earthworm farming device for the degradation of cow manure to solve the above problems. Summary of the Invention

[0006] To solve the above problems, the present invention provides the following technical solution: an earthworm breeding device for cow dung degradation, comprising: a support frame; a first breeding trough fixed to the support frame, the first breeding trough having openings at both its upper and lower ends, wherein a supporting mesh is fixed at the lower opening; a second breeding trough spaced below the first breeding trough, the second breeding trough and the first breeding trough being sealed together by an elastic connector, the second breeding trough being horizontally slidably mounted on the support frame; a discharge assembly disposed at the bottom of the second breeding trough; and a horizontal moving assembly having a horizontal moving end, below which a material grabbing assembly is disposed for periodically grabbing and conveying the fermented cow dung into the first breeding trough.

[0007] Furthermore, as a preferred embodiment, the second aquaculture tank is also provided with multiple guiding components, the guiding components including a rotating drum and a motor; the rotating drum is rotatably disposed in the second aquaculture tank and driven by the motor; a light source extending into the rotating drum is also fixed in the second aquaculture tank, the light source is rotatably connected to the rotating drum, and the rotating drum is light-transmitting.

[0008] Furthermore, as a preferred embodiment, the lamp source is provided with a heat insulation cylinder at intervals, and a protective cylinder is fixedly fitted on the outer surface of the heat insulation cylinder, with a heating resistor wound around the outer surface of the protective cylinder.

[0009] Furthermore, as a preferred embodiment, the outer surface of the rotating drum is fixed with a plurality of evenly distributed paddles.

[0010] Furthermore, preferably, both the dial and the rotating drum are thermally conductive.

[0011] Furthermore, as a preferred embodiment, a support wheel assembly is fixed to the side of the second aquaculture tank, and a support rail corresponding to the support wheel assembly is fixed on the bracket; a horizontal oscillation assembly is also provided on the bracket for driving the second aquaculture tank to oscillate horizontally.

[0012] Furthermore, as a preferred embodiment, the horizontal oscillation assembly includes: a base fixed to the support; a telescopic oscillation cylinder fixed to the base and having a telescopic oscillation end; and a slide block slidably disposed on the base and connected to the telescopic oscillation end, wherein the slide block is connected to the second aquaculture tank via a buffer head.

[0013] Furthermore, as a preferred embodiment, the discharge assembly includes: a discharge trough formed at the bottom of the second aquaculture tank; two symmetrically arranged slide rails fixed to the bottom of the second aquaculture tank and located on both sides of the discharge trough, with a slider slidably disposed on each slide rail; a baffle fixed between the two sliders; and a spring plate fixed to one side of the discharge trough, with a spring connecting the spring plate and the baffle.

[0014] Compared with existing technologies, this invention provides an earthworm farming device for the degradation of cow manure, which has the following beneficial effects: First, this invention improves the traditional single-tank structure into a combined design of a fixed first farming tank and a movable second farming tank, utilizing a support mesh to achieve gradual infiltration of materials between the upper and lower layers. When the horizontal oscillation component drives the second farming tank to vibrate, it only needs to bear a portion of the material mass, which is more energy-efficient than the traditional overall vibration mode. The matching inertial drive discharge component achieves passive discharge through a spring-baffle mechanism, automatically opening and closing the discharge trough during vibration using the inertial force difference.

[0015] Secondly, the guiding component of this invention integrates lighting and temperature control functions. The rotating drum, together with the internal light source, forms directional light induction, and the heating resistor wrapped around the outside of the protective cylinder generates a gradient temperature field. By utilizing the earthworm's inherent light- and heat-avoiding characteristics, a three-dimensional guiding effect is formed, reducing the problem of earthworms being accidentally discharged during material discharge.

[0025] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0026] Example: Please refer to Figures 1-8 In this embodiment of the invention, an earthworm farming device for the degradation of cow dung is provided, comprising: a support 3; a first farming trough 4 fixed to the support 3, the first farming trough 4 having openings at both its upper and lower ends, wherein a supporting mesh 11 is fixed at the lower opening; a second farming trough 5 spaced below the first farming trough 4, the second farming trough 5 and the first farming trough 4 being sealed together by an elastic connector 6, the second farming trough 5 being horizontally slidably mounted on the support 3; a discharge assembly disposed at the bottom of the second farming trough 5, the bottom of the second farming trough 5 also having a collection trough 7; and a horizontal moving assembly 1 having a horizontal moving end, below which a material grabbing assembly 2 is disposed for periodically grabbing and conveying the fermented cow dung to the first farming trough 4.

[0027] In this embodiment, the traditional single breeding tank is divided into a first breeding tank 4 and a second breeding tank 5. The first breeding tank 4 is fixed on a support 3 and supported by the support 3. In this way, when the second breeding tank 5 is driven to move horizontally (at the same time, the discharge component starts to discharge material), energy consumption can be greatly reduced. Specifically, when the second breeding tank 5 is driven to move horizontally, the first breeding tank 4 remains stationary. Although the first breeding tank 4 remains stationary, the cow manure fermentation material in the first breeding tank 4 and the cow manure fermentation material in the second breeding tank 5 are piled together. In this case, energy consumption cannot be reduced to a large extent. Therefore, in order to ensure the separation characteristics of the first breeding tank 4 and the second breeding tank 5, in this embodiment, a support grid 11 is provided in the first breeding tank 4. The support grid 11 can support the cow manure fermentation material in the first breeding tank 4 to a certain extent. And because it is grid-shaped, the cow manure fermentation material in the first breeding tank 4 will gradually enter the second breeding tank 5. After some earthworm castings are discharged from the second breeding tank 5, some cow manure fermentation material can still be replenished from the first breeding tank 4.

[0028] In this embodiment, the second aquaculture tank 5 is also provided with a plurality of guiding components, the guiding components including a rotating drum 12 and a motor 13; the rotating drum 12 is rotatably disposed in the second aquaculture tank 5 and is driven by the motor 13; a light source 16 extending into the rotating drum 12 is also fixed in the second aquaculture tank 5, the light source 16 is rotatably connected to the rotating drum 12, and the rotating drum 12 is light-transmitting.

[0029] It is important to note that when periodically discharging earthworm castings from the second rearing tank 5 using the discharge assembly, the earthworms need to be guided to the upper part of the second rearing tank 5, i.e., away from the discharge assembly, to prevent them from being discharged as well. Since earthworms are photophobic, the use of a light source 16 within the rotating drum 12 can partially address this issue. Furthermore, driving the rotating drum 12 during discharge improves the discharge efficiency.

[0030] It is foreseeable that although the light source 16 set in the rotating drum 12 can solve the problem of earthworms being accidentally discharged to a certain extent, the illumination range of the light source is limited and some areas are difficult to be illuminated. In order to make up for this defect, in this embodiment, the light source 16 is fitted with a heat insulation cylinder 18 at intervals, and a protective cylinder 15 is fixedly fitted on the outer surface of the heat insulation cylinder 18. A heating resistor 17 is wound on the outer surface of the protective cylinder 15.

[0031] It should be explained that earthworms also have heat-avoidance properties. By setting up a heating resistor 17 in conjunction with a light source 16, the problem of earthworms being accidentally expelled can be largely solved.

[0032] Furthermore, a plurality of evenly distributed levers 14 are fixed on the outer surface of the rotating drum 12.

[0033] Both the dial 14 and the rotating cylinder 12 are thermally conductive.

[0034] For example, the lever 14 is made of iron, while the rotating cylinder 12 is made of transparent alumina ceramic. Through a high-temperature sintering process, the alumina grains are highly compacted, reducing pores and impurities and forming transparent grain boundaries. The lattice integrity of high-purity alumina ensures efficient heat conduction.

[0035] In this embodiment, a support wheel set 8 is fixed to the side of the second aquaculture tank 5, and a support rail 10 corresponding to the support wheel set 8 is fixed on the bracket 3; a horizontal oscillation component 9 is also provided on the bracket 3 to drive the second aquaculture tank 5 to oscillate horizontally.

[0036] For example, two support wheel sets 8 are provided on each of the two side walls of the second aquaculture tank 5. Therefore, four support rails 10 corresponding to the support wheel sets 8 are fixed on the bracket 3, thereby improving the stability of the movement of the second aquaculture tank 5.

[0037] Specifically, the horizontal oscillation assembly 9 includes: a base 91, which is fixed on the bracket 3; a telescopic oscillation cylinder 92, which is fixed on the base 91 and has a telescopic oscillation end; and a slide 93, which is slidably disposed on the base 91 and connected to the telescopic oscillation end. The slide 93 is connected to the second aquaculture tank 5 through a buffer head 94.

[0038] For example, two mounting plates are provided on both side walls of the second aquaculture tank 5. Therefore, four horizontal oscillation components 9 corresponding to the mounting plates are provided on the bracket 3, wherein the buffer head 94 is connected to the mounting plate.

[0039] In addition, the buffer head 94 is any one or a combination of spring, elastic pad, and shock-absorbing cylinder. By setting the buffer head 94, the stability of the horizontal oscillation component 9 can be guaranteed.

[0040] In this embodiment, the discharge assembly includes: a discharge trough 19 formed at the bottom of the second aquaculture tank 5; two symmetrically arranged slide rails 24 fixed to the bottom of the second aquaculture tank 5 and located on both sides of the discharge trough 19, with a slider 21 slidably arranged on each slide rail 24 (the slide rail 24 and the slider 21 can form a dovetail fit); a baffle 20 fixed between the two sliders 21; and a spring plate 22 fixed to one side of the discharge trough 19, with a spring 23 connecting the spring plate 22 and the baffle 20.

[0041] In a static state, the spring 23 holds the baffle 20 at the opening of the discharge trough 19 by its elastic force. When the horizontal oscillation component 9 drives the second breeding tank 5 to perform horizontal reciprocating vibration, a relative motion tendency is generated between the second breeding tank 5 and the baffle 20. That is, during the process of the second breeding tank 5 being driven to move horizontally by the horizontal oscillation component 9, the baffle 20 will move relative to the discharge trough 19 under the action of inertial force, thereby causing the discharge trough 19 to be in a state of blocking and unblocking, thereby realizing the discharge.

[0042] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
