Description

Technical Field

[0001] This utility model relates to the field of livestock excrement cleaning technology, specifically to a livestock excrement conveying device with solid-liquid separation function. Background Technology

[0002] In the poultry and livestock farming industry, the excrement, such as feces and urine produced by poultry and livestock, generally seeps downward through a slatted floor. A circulating conveyor belt is arranged below the slatted floor to transport the excrement to a collection trough for centralized treatment.

[0003] Excrement contains a mixture of solids and liquids, requiring solid-liquid separation for subsequent recycling. In existing technologies, circulating conveyor belts typically transport the mixed solids and liquids of excrement together to a collection tank for separation. However, in practice, it has been found that solids partially dissolve into the liquids, hindering timely separation and impacting subsequent use. Therefore, improvements to existing conveying devices are needed to address these issues. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a livestock excrement conveying device with solid-liquid separation function, which solves the technical problem in the prior art where solid and liquid excrement are not separated in time, affecting subsequent recycling.

[0005] According to one aspect, at least one embodiment of the present invention provides a livestock excrement conveying device with solid-liquid separation function, comprising a manure slat plate, a side baffle, a circulating conveyor belt and a liquid collection tank arranged sequentially from top to bottom, wherein the circulating conveyor belt has a plurality of fine holes arranged along its length direction, the fine holes being used for liquid excrement to leak into the liquid collection tank.

[0006] As a further technical solution, the circulating conveyor belt includes an upper conveyor belt and a lower conveyor belt, and an upper vibrating plate and a lower vibrating plate are provided between the upper conveyor belt and the lower conveyor belt. The upper vibrating plate is used to vibrate the upper conveyor belt after it is raised and lowered, and the lower vibrating plate is used to vibrate the lower conveyor belt after it is raised and lowered.

[0007] As a further technical solution, the bottom of the upper vibrating plate is provided with a guide sleeve, and a push rod is provided in the guide sleeve for lifting and lowering. An elastic element is connected between the upper vibrating plate and the lower vibrating plate. The push rod is configured to push the upper vibrating plate back and forth after lifting and lowering to vibrate the upper conveyor belt, and drive the lower vibrating plate to vibrate the lower conveyor belt through the elastic element.

[0008] As a further technical solution, a turntable is rotatably provided below the push rod, and the rotation axis of the turntable is parallel to the width extension direction of the circulating conveyor belt. A crank is also provided between the push rod and the turntable. One end of the crank is rotatably connected to the push rod, and the other end is rotatably connected to a non-center position of the turntable. The turntable is configured to drive the push rod to rise and fall through the crank after rotation.

[0009] As a further technical solution, the circulating conveyor belt has a manure discharge end, and a solid collection trough is provided below the manure discharge end, with the solid collection trough located on one side of the liquid collection trough.

[0010] As a further technical solution, a rotatable roller is provided on one side of the manure discharge end, and a rotatable brush is provided on the rotatable roller, with the solid collection trough located below the rotatable roller.

[0011] As a further technical solution, the side baffle has an inclined guide surface, which is used to guide the excrement onto the circulating conveyor belt.

[0012] The beneficial effects of this utility model are as follows: In this invention, a complete system for receiving, conveying, and separating solids and liquids is formed by arranging a slatted floor, side baffles, a perforated conveyor belt, and a liquid collection tank in a top-to-bottom order. The perforations on the conveyor belt directly serve as seepage channels for the liquid excrement. Combined with the liquid collection tank below, this allows the liquid excrement to seep into the collection tank simultaneously during the conveyor belt's transport process. This eliminates the need to first collect the solid-liquid mixture before separation, structurally avoiding the problem of solid excrement partially dissolving into the liquid excrement in existing technologies, thus ensuring the efficient recycling of both solid and liquid excrement. The side baffles prevent excrement from scattering from both sides of the conveyor belt during transport. Attached Figure Description

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] In the livestock farming industry, timely treatment and solid-liquid separation of livestock excrement are crucial for ensuring a clean farming environment and subsequent resource recycling. In existing technologies, excrement is typically mixed and transported before centralized separation, which can lead to the partial dissolution of solid excrement in the liquid, affecting subsequent treatment effectiveness. The livestock excrement conveying device with solid-liquid separation function provided in this embodiment can simultaneously perform solid-liquid separation during transport, making it suitable for centralized excrement treatment scenarios in large-scale livestock farms.

[0022] like Figure 1 The diagram illustrates the three-dimensional structure of a conveying device according to an embodiment of the present invention. The conveying device, arranged vertically from top to bottom, comprises a manure-slatting plate 1, side baffles 2, a circulating conveyor belt 3, and a liquid collection tank 4. The side baffles 2 surround both sides of the circulating conveyor belt 3 and connect with the edges of the manure-slatting plate 1, forming a conveying channel for excrement. The circulating conveyor belt 3 has several fine holes 31 extending along its length and covering its effective conveying area. The liquid collection tank 4 is positioned below the circulating conveyor belt 3, with its opening opposite the lower surface of the belt, to collect liquid excrement leaking from the fine holes 31. One end of the circulating conveyor belt 3 is a manure-feeding end 34, below which is a solid collection tank 11 located to one side of the liquid collection tank 4; the two are spatially independent. The surface of the side baffle 2 facing the inner side of the circulating conveyor belt 3 is a guide surface 21. This guide surface 21 gradually slopes downwards in the vertical direction towards the center of the circulating conveyor belt 3 to ensure that the falling excrement can be guided to the effective area of ​​the circulating conveyor belt 3. A deflector roller 12 is rotatably installed on one side of the manure discharge end 34. The rotation axis of the deflector roller 12 is parallel to the width direction of the circulating conveyor belt 3. Several deflector brushes 121 are fixed on its outer circumference. The ends of the deflector brushes 121 are in contact with the surface of the circulating conveyor belt 3. The solid collection trough 11 is set below the deflector roller 12 to receive the solid excrement cleaned by the deflector brushes 121.

[0023] In this embodiment, by arranging the slatted floor 1, side baffles 2, a circulating conveyor belt 3 with perforations 31, and a liquid collection tank 4 in a top-to-bottom order, a complete system for receiving, conveying, and separating solid and liquid waste is formed. The perforations 31 on the circulating conveyor belt 3 directly serve as leakage channels for liquid waste. Combined with the liquid collection tank 4 below, this allows liquid waste to simultaneously leak into the liquid collection tank 4 during the conveying process with the circulating conveyor belt 3. There is no need to first collect the solid-liquid mixture of waste before separation, structurally avoiding the problem of solid waste partially dissolving into liquid waste in existing technologies, thus ensuring the subsequent recycling and reuse of both solid and liquid waste. The side baffles 2 prevent waste from scattering from both sides of the circulating conveyor belt 3 during transport.

[0024] As shown in Figure 2, the circulating conveyor belt 3 specifically includes an upper conveyor belt 32 and a lower conveyor belt 33, which are connected by drive rollers at their ends to form a closed loop path. The upper conveyor belt 32 is located in the upper horizontal conveying section, and the lower conveyor belt 33 is located below the upper conveyor belt 32. An upper vibrating plate 5 and a lower vibrating plate 6 are provided between the upper conveyor belt 32 and the lower conveyor belt 33. The top surface of the upper vibrating plate 5 is opposite to the lower surface of the upper conveyor belt 32, and the bottom surface of the lower vibrating plate 6 is opposite to the upper surface of the lower conveyor belt 33. Both the upper vibrating plate 5 and the lower vibrating plate 6 can move up and down in the vertical direction.

[0025] As shown in Figure 3, a guide sleeve 51 is fixed to the bottom of the upper vibrating plate 5. The guide sleeve 51 extends vertically, and a push rod 7 is slidably installed inside it. The top end of the push rod 7 is adapted to the inner wall of the guide sleeve 51, allowing it to move stably up and down along the axis of the guide sleeve 51. An elastic element 8 connects the upper vibrating plate 5 and the lower vibrating plate 6. The two ends of the elastic element 8 are fixed to the bottom surface of the upper vibrating plate 5 and the top surface of the lower vibrating plate 6, respectively, to achieve linkage between the two.

[0026] As shown in Figure 4, a turntable 9 is located below the push rod 7. The turntable 9 is rotatably mounted via a bracket, and its rotation axis is parallel to the width extension direction of the circulating conveyor belt 3. A crank 10 is connected between the push rod 7 and the turntable 9. One end of the crank 10 is rotatably connected to the bottom end of the push rod 7, and the other end is rotatably connected to a non-central position of the turntable 9, forming a crank 10 linkage mechanism. When the turntable 9 rotates, the crank 10 can drive the push rod 7 to reciprocate up and down along the guide sleeve 51.

[0027] The device operates as follows: Livestock excrement first falls through the slatted floor 1. Some excrement landing on the edge of the slatted floor 1 contacts the guide surface 21 of the side baffle 2 and slides along the inclined guide surface 21 to the effective conveying area of ​​the circulating conveyor belt 3. During operation, the liquid mixed in the excrement seeps downwards through the fine holes 31 under gravity and falls into the liquid collection tank 4 below for collection. Simultaneously, the turntable 9 rotates under external force, driving the push rod 7 to reciprocate up and down along the guide sleeve 51 via the crank 10. As the push rod 7 rises and falls, it pushes the upper vibrating plate 5, which vibrates the upper conveyor belt 32, accelerating the leakage of liquid excrement from the fine holes 31. The movement of the upper vibrating plate 5 is transmitted to the lower vibrating plate 6 via the elastic element 8. The lower vibrating plate 6 synchronously vibrates the lower conveyor belt 33, cleaning residual liquid and debris from the surface of the lower conveyor belt 33 and preventing blockage of the fine holes 31. Solid excrement is transported to the lower end 34 by the circulating conveyor belt 3 and falls down along the inclined end. During this process, the agitator roller 12 rotates synchronously, driving the agitator brush 121 to sweep across the surface of the circulating conveyor belt 3, completely removing the attached solid excrement. The removed solid excrement falls into the solid collection tank 11 below, completing the separate treatment of solid and liquid excrement.

[0028] In this embodiment, some terms are explained as follows: the circulating conveyor belt 3 refers to the closed conveying structure composed of the upper conveyor belt 32 and the lower conveyor belt 33, which is used to realize the continuous conveying of excrement; the crank 10 linkage mechanism refers to the transmission structure composed of the crank 10, the push rod 7 and the turntable 9, which can convert the rotational motion into linear reciprocating motion; the effective conveying area refers to the area on the circulating conveyor belt 3 that can receive and convey excrement, that is, the area covered by the fine holes 31.

[0029] The beneficial effects of this device are as follows: By setting fine holes 31 on the circulating conveyor belt 3, in conjunction with the liquid collection tank 4 below, liquid excrement can be simultaneously leaked and separated during the conveying process, avoiding the problem of solid dissolution caused by solid-liquid mixing and subsequent separation, thus ensuring the effectiveness of subsequent recycling. The guide surface 21 of the side baffle 2 can guide the scattered excrement to the effective area of ​​the circulating conveyor belt 3, ensuring that all excrement can pass through the area of ​​fine holes 31, guaranteeing the comprehensiveness of solid-liquid separation. The upper vibrating plate 5 and the lower vibrating plate 6 apply vibration to the upper and lower conveyor belts 33 respectively. The upper vibrating plate 5 accelerates liquid leakage, while the lower vibrating plate 6 cleans up residual debris. The two work together to improve separation efficiency and the cleanliness of the conveyor belt. The guide sleeve 51 provides directional constraint for the push rod 7, ensuring the stability of the push rod 7's lifting and lowering movement, avoiding uneven force on the upper vibrating plate 5, while the elastic element 8 can buffer the impact force of the push rod 7, extending the service life of the device. The transmission structure consisting of turntable 9 and crank 10 can stably convert rotational motion into the reciprocating lifting and lowering of push rod 7. The vibration frequency can be controlled by adjusting the rotation speed of turntable 9 to adapt to the separation needs of different types of excrement. The inclined structure of the manure discharge end 34, together with the solid collection trough 11, allows solid excrement to fall directly into the dedicated collection space, avoiding re-mixing with liquid. The independent layout of solid collection trough 11 and liquid collection trough 4 facilitates separate subsequent processing, saving space and reducing energy consumption. The agitator roller 12 and agitator brush 121 can thoroughly clean residual solids on the surface of the conveyor belt, ensuring the integrity of solid collection and avoiding incomplete conveying problems caused by adhesion.

[0030] Optionally, the elastic element 8 can be a spring or elastic rubber, or other components with elastic reset function, as long as it can achieve linkage between the upper vibrating plate 5 and the lower vibrating plate 6. The turntable 9 can be driven by a motor, connected to the turntable 9 via a belt or gear to achieve stable rotation. Furthermore, the tilt angle of the guide surface 21 of the side baffle 2 can be adjusted according to the needs of the actual breeding scenario to accommodate different amounts of excrement falling. A guide channel can be set in the liquid collection tank 4 to facilitate guiding the collected liquid excrement to a designated location for subsequent processing. The fine holes 31 on the circulating conveyor belt 3 can be arranged in multiple rows evenly to further improve the efficiency of liquid leakage. These extended solutions can all achieve the core function of this device and conform to the application logic of existing technology, and can be flexibly selected according to actual needs.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
