Description

Technical Field

[0001] The present invention relates to the technical field of earthworm breeding, and particularly to an earthworm breeding device for cow dung degradation. Background Art

[0002] In the beef cattle breeding industry, the treatment and resource utilization of cow dung are key issues restricting the sustainable development of the industry. The earthworm breeding technology has gradually become an important technical path for cow dung treatment due to its characteristic of converting cow dung into high-value-added earthworm manure and earthworm protein. However, there are still certain technical bottlenecks in the engineering application of existing earthworm breeding devices.

[0003] Existing earthworm breeding devices generally adopt a single-tank integral structure, and the driving mechanism needs to drive all the breeding substrates to vibrate to achieve the discharging function. This design has technical defects: firstly, the energy consumption is positively correlated with the material quality. When the treatment scale expands, the driving energy consumption increases exponentially, resulting in high operating costs for large-scale farms; secondly, the discharging component needs to rely on an independent power source, and an additional motor or hydraulic system needs to be configured, further increasing the energy consumption.

[0004] In the process of earthworm breeding, the discharging link is a key link affecting the breeding efficiency and product quality. There is a significant risk of accidental discharge of earthworms in the traditional device during discharging. The accidental discharge of earthworms will bring a series of problems: firstly, the accidentally discharged earthworms will be discharged from the device together with the earthworm manure, resulting in a waste of earthworm resources and a reduction in earthworm production; secondly, the accidental discharge of earthworms will also increase the cost and time of manual sorting, reducing the overall breeding efficiency.

[0005] Therefore, it is necessary to provide an earthworm breeding device for cow dung degradation 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 bracket; a first breeding tank fixed on the bracket, both the upper and lower ends of the first breeding tank have openings, wherein a support grid is fixed at the lower opening; a second breeding tank spaced below the first breeding tank, the second breeding tank is hermetically connected to the first breeding tank through an elastic connector, and the second breeding tank is horizontally slidably arranged on the bracket; a discharging component arranged at the bottom of the second breeding tank; a horizontal moving component having a horizontal moving end, and a material grabbing component is arranged below the horizontal moving end for regularly grabbing the cow dung fermentation product and sending it into the first breeding tank.

[0007] Further, preferably, a plurality of guiding components are also arranged in the second breeding tank. The guiding components include a rotary drum and a motor. The rotary drum is rotatably arranged in the second breeding tank and is driven by the motor. A light source extending into the interior of the rotary drum is also fixed in the second breeding tank. The light source is rotatably connected to the rotary drum, and the rotary drum has light transmissivity.

[0008] Further, preferably, a heat insulation cylinder is sleeved outside the light source at intervals. A protection cylinder is fixedly sleeved on the outer surface of the heat insulation cylinder, and a heating resistor is wound on the outer surface of the protection cylinder.

[0009] Further, preferably, a plurality of uniformly distributed baffle plates are fixed on the outer surface of the rotary drum.

[0010] Further, preferably, both the baffle plates and the rotary drum have heat conductivity.

[0011] Further, preferably, a support wheel set is fixed on the side of the second breeding tank, and a support track corresponding to the support wheel set is fixed on the bracket. A horizontal oscillation component is also arranged on the bracket for driving the second breeding tank to perform horizontal oscillation.

[0012] Further, preferably, the horizontal oscillation component includes: a base fixed on the bracket; a telescopic oscillation cylinder fixed on the base and having a telescopic oscillation end; a sliding seat slidably arranged on the base and connected to the telescopic oscillation end, and the sliding seat is connected to the second breeding tank through a buffer head.

[0013] Further, preferably, the discharging component includes: a discharging groove opened at the bottom of the second breeding tank; two symmetrically arranged slide rails fixed at the bottom of the second breeding tank and located on both sides of the discharging groove, and sliders are slidably arranged on each of the slide rails; a baffle plate fixed between the two sliders; a spring plate fixed on one side of the discharging groove, and a spring is connected between the spring plate and the baffle plate.

[0014] Compared with the prior art, the present invention provides an earthworm breeding device for cow dung degradation, having the following beneficial effects: First, by improving the traditional single-tank structure into a combined design of a fixed first breeding tank and a movable second breeding tank, the present invention uses a support grid to achieve progressive penetration of upper and lower layer materials. When the horizontal oscillation component drives the second breeding tank to vibrate, it only needs to bear part of the material mass, which is more energy-saving than the traditional overall vibration mode. The supporting inertial-driven discharging component realizes passive discharging through a spring-baffle mechanism, and automatically opens and closes the discharging groove by using the inertial force difference during the vibration process.

[0015] Second, in the present invention, the guiding component integrates the functions of light and temperature control. Among them, the rotating cylinder cooperates with the internal light source to form directional light induction, combines with the heating resistor wound outside the protective cylinder to generate a gradient temperature field, and utilizes the inherent light and heat avoidance characteristics of earthworms to form a three-dimensional guiding effect, reducing the problem of earthworms being accidentally discharged during material discharge.

[0025] The terms "first", "second", etc. in the description, claims, and the above accompanying drawing descriptions of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that these terms can be interchanged under appropriate circumstances, which is merely a way of distinguishing objects with the same attributes when describing embodiments of this application. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, so that a process, method, system, product, or device comprising a series of units does not have to be limited to those units, but may include other units not clearly listed or inherent to these processes, methods, products, or devices.

[0026] Embodiment: Please refer to Figures 1-8 , in an embodiment of the present invention, a vermiculture device for cow dung degradation is provided, including: a bracket 3; a first breeding tank 4 fixed to the bracket 3, with openings at both the upper and lower ends of the first breeding tank 4, wherein a support grid 11 is fixed at the lower opening; a second breeding tank 5 spaced below the first breeding tank 4, and the second breeding tank 5 is hermetically connected to the first breeding tank 4 through an elastic connector 6, and the second breeding tank 5 is horizontally slidably arranged on the bracket 3; a discharging assembly arranged at the bottom of the second breeding tank 5, and a collection tank 7 is also arranged at the bottom of the second breeding tank 5; a horizontal moving assembly 1 having a horizontal moving end, and a material grasping assembly 2 is arranged below the horizontal moving end for regularly grasping cow dung fermented material and sending it into the first breeding tank 4.

[0027] In this embodiment, the traditional single breeding tank is divided into a first breeding tank 4 and a second breeding tank 5. Among them, the first breeding tank 4 is fixed on the bracket 3 and supported by the bracket 3. Thus, when driving the second breeding tank 5 to move horizontally (meanwhile, the discharging assembly starts discharging), the energy consumption can be greatly reduced. Specifically, when driving the second breeding tank 5 to move horizontally, the first breeding tank 4 remains stationary. Although the first breeding tank 4 remains stationary, the cow dung fermented material in the first breeding tank 4 and the cow dung fermented material in the second breeding tank 5 are piled up together. In this case, the energy consumption cannot be greatly reduced. 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 arranged in the first breeding tank 4. The support grid 11 can support the cow dung fermented material in the first breeding tank 4 to a certain extent. And because it is grid-shaped, the cow dung fermented material in the first breeding tank 4 will gradually enter the second breeding tank 5, and after the second breeding tank 5 discharges part of the earthworm manure, it can still be supplemented with part of the cow dung fermented material from the first breeding tank 4.

[0028] In this embodiment, a plurality of guiding components are further arranged in the second breeding tank 5. The guiding components include a rotating cylinder 12 and a motor 13. The rotating cylinder 12 is rotatably arranged in the second breeding tank 5 and is driven by the motor 13. A light source 16 extending into the interior of the rotating cylinder 12 is also fixed in the second breeding tank 5. The light source 16 is rotationally connected to the rotating cylinder 12, and the rotating cylinder 12 has light transmittance.

[0029] It should be noted that when regularly discharging earthworm manure from the second breeding tank 5 by using the discharging component, it is necessary to guide the earthworms to the upper space of the second breeding tank 5, that is, away from the discharging component, so as to prevent the earthworms from being discharged by the discharging component. And earthworms have light avoidance property. Therefore, by using the light source 16 arranged in the rotating cylinder 12, this problem can be solved to a certain extent. And when discharging, by driving the rotating cylinder 12 to rotate, the discharging effect can be improved.

[0030] It can be foreseen that although the light source 16 arranged in the rotating cylinder 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 places are difficult to be irradiated. To make up for this defect, in this embodiment, a heat insulation cylinder 18 is sleeved at intervals outside the light source 16, a protection cylinder 15 is fixedly sleeved on the outer surface of the heat insulation cylinder 18, and a heating resistor 17 is wound on the outer surface of the protection cylinder 15.

[0031] It should be explained that earthworms also have heat avoidance property. By arranging the heating resistor 17 in cooperation with the light source 16, the problem of earthworms being accidentally discharged can be solved to a great extent.

[0032] Furthermore, a plurality of uniformly distributed baffle plates 14 are fixed on the outer surface of the rotating cylinder 12.

[0033] Both the baffle plate 14 and the rotating cylinder 12 have heat conductivity.

[0034] For example, the baffle plate 14 is made of iron material, and the rotating cylinder 12 is made of transparent alumina ceramic material. Among them, through the high-temperature sintering process, the alumina grains are highly densified, the pores and impurities are reduced, and a transparent grain boundary is formed. And the lattice integrity of high-purity alumina ensures high-efficiency heat conduction.

[0035] In this embodiment, a support wheel set 8 is fixed on the side of the second breeding tank 5, and a support track 10 corresponding to the support wheel set 8 is fixed on the bracket 3. A horizontal oscillation component 9 is also arranged on the bracket 3 for driving the second breeding tank 5 to perform horizontal oscillation.

[0036] Exemplarily, two support wheel sets 8 are arranged on both side walls of the second breeding tank 5. Therefore, four support tracks 10 corresponding to the support wheel sets 8 are fixed on the bracket 3, so as to improve the stability of the movement of the second breeding tank 5.

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

[0038] Exemplarily, two mounting plates are provided on both side walls of the second breeding tank 5. Therefore, four horizontal oscillation assemblies 9 corresponding to the mounting plates are provided on the bracket 3, wherein the buffer heads 94 are correspondingly connected to the mounting plates.

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

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

[0041] In the static state, the spring 23 keeps the baffle 20 at the opening of the discharging groove 19 by elastic force. When the horizontal oscillation assembly 9 drives the second breeding tank 5 to perform horizontal reciprocating vibration, a relative movement tendency is generated between the second breeding tank 5 and the baffle 20, that is, in the process of driving the second breeding tank 5 to perform horizontal reciprocating movement by the horizontal oscillation assembly 9, the baffle 20 will move relative to the discharging groove 19 under the action of inertia force, so that the discharging groove 19 is in a state change of being blocked - unblocked, and thus discharging is realized.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
