Description

Technical Field

[0001] This utility model relates to the field of cow bedding material recycling technology, and more specifically to an efficient integrated equipment for separating and recycling dairy cow manure bedding material. Background Technology

[0002] Currently, with the rapid increase in the number of dairy cows in my country, large-scale and intensive dairy farms and dairy communities are gradually increasing. This growth in the number of dairy cows means that the area of ​​dairy farms is also expanding. The rapid increase in the number of dairy cows has led to the problem of ineffective treatment and utilization of farm manure, which is becoming a major issue affecting the pastoral environment and restricting farm production. However, the cow bedding recycling system not only enables the resource utilization of dairy farm manure but also solves the problem of bedding source, effectively improving the environmental pollution situation of dairy farms and generating certain economic benefits.

[0003] However, in large dairy farms, the area covered by bedding is also large. While existing regenerable cow bedding systems can regenerate manure bedding, these systems are mostly fixed in a certain location on the dairy farm. Farm staff need to transport the manure bedding to the system for processing, and then transport the regenerated bedding back to the barn. This increases the cost of round-trip transportation and reduces work efficiency.

[0004] Therefore, how to provide an integrated and mobile dairy cow manure bedding separation and recycling device to improve work efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an integrated equipment for separating and regenerating dairy cow manure bedding material. By integrating a conveyor belt, a solid-liquid separation device, and a drying and fermentation device into one unit, and by equipping it with wheels to move it to an area close to the cowshed bedding material, the transportation process of the bedding material is reduced and the regeneration efficiency of the bedding material is improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency integrated equipment for separating and regenerating dairy cow manure bedding includes:

[0008] A drying fermentation box, comprising a box body and a drying fermentation component installed inside it, wherein the inlet end of the drying fermentation component is arranged near the top of the box body, and a recycled pad material outlet is provided on one side wall of the box body corresponding to the outlet end of the drying fermentation component.

[0009] A recycled bedding material outlet cover plate, which is hingedly installed at the recycled bedding material outlet;

[0010] A solid-liquid separation box, comprising a box body two and a solid-liquid separation component installed inside it, wherein the feed end of the solid-liquid separation component is arranged near the top of the box body two, and the discharge end is arranged near the bottom of the box body two and communicates with the feed end of the drying fermentation component; a towing rod that can be connected to a tractor is fixedly installed on the outer side wall of the box body two near the outlet cover of the recycled pad material.

[0011] The feed cylinder is fixedly installed on the top of the second housing corresponding to the feed end of the solid-liquid separation component, and its side wall has a feed inlet.

[0012] The padding material conveying unit includes multiple supports and a padding material conveying belt mounted on the supports. Each support includes telescopic legs and multiple fixed supports. The telescopic legs are supported on the ground on the side corresponding to one side of the housing. The upper surfaces of the multiple fixed supports form inclined surfaces and are spaced apart and mounted on the outer side wall of the housing. The padding material conveying belt includes a horizontal feeding section, an inclined conveying section, and a horizontal discharge section, which are sequentially connected and driven onto the telescopic legs and the multiple fixed supports. The feeding section is arranged close to the ground and its top surface is parallel to the ground. The telescopic legs are hinged to both ends of the feeding section. The discharge section is arranged close to the top of the housing and its top surface is parallel to the top surface of the housing. The end of the discharge section is located inside the feed cylinder. The intermediate conveying section connects the feeding section and the discharge section, and both ends of the intermediate conveying section are fixedly connected to the fixed supports.

[0013] The wheels are multiple and arranged in an array on the bottom surface of the drying fermentation tank.

[0014] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a highly efficient integrated equipment for separating and regenerating dairy cow manure bedding. The integrated equipment is towed by a tractor to the vicinity of the cowshed area where bedding needs to be replaced. Then, the tractor is disconnected, the recycled bedding outlet cover is opened, and the telescopic outriggers of the conveyor belt are rotated so that their bottom ends are supported on the ground, completing the temporary fixing process of the integrated equipment. Afterwards, the manure bedding regeneration process can begin. The manure bedding is conveyed to the feed cylinder via the conveyor belt and then enters the solid-liquid separation tank. The solid-liquid separation component performs solid-liquid separation on the manure bedding. The separated solid bedding is then conveyed to the drying and fermentation tank for drying, completing the bedding regeneration process. Finally, the recycled bedding is discharged from the recycled bedding outlet. After completing the bedding regeneration task in this area, the recycled bedding outlet cover can be closed, and the traction rod on the recycled bedding outlet cover can be connected to the tractor to transport the bedding to the next target area to complete the bedding regeneration task in the next area. Therefore, this high-efficiency integrated dairy cow manure bedding separation and recycling equipment can be moved by traction according to usage, which facilitates the bedding recycling process, reduces the time cost of reciprocating bedding transportation, and improves the recycling efficiency of bedding.

[0015] Furthermore, it also includes an equipment box, which is fixedly installed on one end face of the box body away from the recycled pad material outlet, and the equipment box is equipped with a power supply device and a controller.

[0016] The beneficial effects of adopting the above technical solution are as follows: Through the controller inside the equipment box, centralized control of various parts such as the solid-liquid separation component, the drying and fermentation component, and the bedding conveyor belt can be easily realized. Operators can control the start-up, stop, speed adjustment, and other operations of the equipment from near the equipment box or through remote control, realizing automated operation of the equipment, reducing manual intervention, and improving the level of production automation. Furthermore, since the equipment box is fixedly connected to the main parts such as the drying and fermentation box, it is easier to operate when the equipment needs to be moved or installed as a whole, without having to consider the installation location and connection of the power supply device and controller separately, thus improving the flexibility and operability of the equipment.

[0017] Furthermore, it also includes a return water tank, which is fixedly installed on the side end face of the equipment box away from the box body. The return water tank is a water storage chamber, which is connected to a drain pipe and a valve is installed on the drain pipe.

[0018] The beneficial effects of adopting the above technical solution are: using the water collected in the return water tank for cleaning, stirring and other processes of the equipment can effectively reduce the dependence on fresh water sources, reduce water costs during equipment operation, and improve the efficiency of water resource utilization. This advantage is even more obvious in areas where water resources are relatively scarce.

[0019] Furthermore, a placement plate is fixedly installed on the outer wall of the return water tank corresponding to the telescopic support leg, and the telescopic support leg can be overlapped on the two placement plates.

[0020] The beneficial effects of adopting the above technical solution are: by setting up a placement plate, it is convenient to release the support state of the telescopic outriggers when it is necessary to move the equipment, and place the telescopic outriggers on the placement plate to provide them with placement space, thus avoiding the telescopic outriggers from contacting and rubbing against the ground when moving.

[0021] Furthermore, the solid-liquid separation assembly includes a auger spiral solid-liquid separation drum, a drive motor, and a liquid collection funnel. The auger spiral solid-liquid separation drum is installed radially inside the housing two along the feed cylinder, and the side wall of the auger spiral solid-liquid separation drum is connected to the lower opening of the feed cylinder. The auger spiral solid-liquid separation drum is supported by multiple support rods against the inner side wall of the housing two. A rotating shaft rotates coaxially inside the auger spiral solid-liquid separation drum. The drive motor is installed at one end of the auger spiral solid-liquid separation drum and is connected to the rotating shaft. The drive motor is electrically connected to the power supply device and the controller. The side wall of the auger spiral solid-liquid separation drum is a filter screen layer. The liquid collection funnel is installed inside the housing two and located below the auger spiral solid-liquid separation drum. A return pipe is connected to the bottom end of the liquid collection funnel, and the other end of the return pipe is connected to the water storage chamber.

[0022] The beneficial effects of adopting the above technical solution are as follows: the side wall of the auger spiral solid-liquid separation drum is a filter screen layer, which enhances the solid-liquid separation effect. During the material being propelled, the liquid portion can flow out through the mesh of the filter screen layer, while the solid portion is blocked inside the auger spiral solid-liquid separation drum and continues to be conveyed forward. The pore size of the filter screen layer can be selected according to actual needs to adapt to the separation requirements of solid materials with different particle sizes, ensuring that the separated solid material has good dryness and purity; the liquid collection funnel is installed inside the solid-liquid separation box and located below the auger spiral solid-liquid separation drum, and its position and shape design can effectively collect the liquid flowing out from the filter screen layer. Because liquids fall naturally under gravity, the liquid collection funnel can gather dispersed droplets into a stream and guide it to the bottom of the funnel, thus achieving centralized collection of the liquid. This prevents the liquid from flowing around in the solid-liquid separation tank, improving the efficiency and cleanliness of liquid collection. Furthermore, the collected liquid is transported to the storage chamber of the return water tank through the return pipe. In this way, the separated liquid can be effectively recycled and reused, reducing dependence on fresh water sources, lowering equipment operating costs, reducing wastewater discharge, and improving the resource utilization efficiency and sustainability of the entire equipment system.

[0023] Furthermore, the solid-liquid separation assembly also includes a solid-liquid separation degree adjustment assembly, which includes an installation sleeve, a conical plug, a screw, and a rotating handle. The installation sleeve is coaxially arranged with the auger spiral solid-liquid separation drum, with one end fixed to the inner side wall of the second housing, and the other end spaced apart from the discharge port of the auger spiral solid-liquid separation drum. The conical plug is slidably installed inside the installation sleeve, with its conical tip facing the discharge port of the auger spiral solid-liquid separation drum. One end of the screw is fixedly connected to the flat end of the conical plug, and the other end passes through the side wall of the second housing. The rotating handle is located on the outside of the second housing and is fixedly connected to the other end of the screw.

[0024] The beneficial effects of adopting the above technical solution are as follows: By rotating the screw through the handle, the conical plug can slide back and forth within the mounting sleeve, thereby achieving precise adjustment of the discharge port size of the spiral solid-liquid separator. When it is necessary to reduce the discharge rate, the conical plug can be pushed towards the discharge port, causing its cone tip to penetrate deeper into the discharge port, reducing the cross-sectional area of ​​the discharge port; conversely, if it is necessary to increase the discharge rate, the conical plug can be pulled outward, widening the discharge port. This flexible adjustment method allows for real-time adjustment of the discharge speed and quantity according to actual production needs and material characteristics, ensuring that the equipment's operating efficiency and separation effect reach their optimal state.

[0025] Furthermore, the solid-liquid separation degree adjustment component also includes a limiting rod, which is fixedly installed on its outer side wall perpendicular to the screw, and the limiting rod is arranged at intervals with the outer side wall of the second housing.

[0026] The beneficial effects of adopting the above technical solution are as follows: the limiting rod is vertically fixed on the outer wall of the screw, and the limiting rod is spaced apart from the side wall of the solid-liquid separation tank. When the handle is turned to drive the screw to rotate, the limiting rod will rotate with the screw. By reasonably designing the relative position and distance between the limiting rod and the side wall of the solid-liquid separation tank, the rotation range of the screw can be effectively limited. This prevents the screw from rotating excessively due to improper operation or negligence during the adjustment process, which could cause the conical plug to extend too far into or away from the discharge port of the auger spiral solid-liquid separation drum, resulting in the discharge port being completely blocked or the discharge volume being unable to be effectively adjusted. This ensures that the solid-liquid separation degree adjustment component can work normally and reliably.

[0027] Furthermore, the drying fermentation chamber also includes a conveying assembly, which includes a feeding plate, a main shaft, spiral blades, and a second drive motor. The first chamber body is provided with a material transfer chamber corresponding to the discharge port of the solid-liquid separation assembly. The top of the material transfer chamber is open, and its side wall has a through hole communicating with the feed end of the drying fermentation assembly. The feeding plate is fixed to the bottom wall of the through hole and has a preset inclination angle. The main shaft is arranged along the direction of the top opening of the material transfer chamber and passes through the feeding plate. The spiral blades are fixed around the outer side wall of the main shaft and located above the feeding plate. The second drive motor is located below the feeding plate, and its driving end is connected to the main shaft for transmission. The second drive motor is electrically connected to the power supply device and the controller respectively.

[0028] The beneficial effects of adopting the above technical solution are: the combination of the inclination angle of the feeding plate and the pushing action of the spiral blades can effectively prevent excessive accumulation of materials in the material transfer chamber. Once the material enters the material transfer chamber, it will move forward rapidly under the guidance of the feeding plate and the pushing action of the spiral blades, reducing the residence time of the material in the material transfer chamber, reducing the risk of uneven fermentation and equipment blockage caused by material accumulation, and ensuring the continuity and uniformity of the material conveying process.

[0029] Furthermore, the drying fermentation assembly includes a fermentation drum, a third drive motor, a drive gear, a driven gear, and a drive rack. The fermentation drum is arranged axially along the outlet of the recycled bedding material and its end away from the outlet of the recycled bedding material is connected to the through hole. The third drive motor is located at the bottom of the housing and is electrically connected to the power supply device and the controller, respectively. The drive gear is mounted on both ends of the third drive motor along the axial direction of the fermentation drum via a drive shaft. The driven gear is rotatably mounted on the top of the housing via a shaft. The drive rack is sleeved and fixed on the outer peripheral wall of the fermentation drum. The two drive racks mesh with the symmetrically arranged drive gear and driven gear, respectively, to make the fermentation drum rotate.

[0030] The beneficial effects of adopting the above technical solution are as follows: the fermentation drum is arranged axially along the outlet of the recycled bedding material, and its internal space is connected to the through holes, providing a closed fermentation environment with a large volume for the material. When the fermentation drum rolls under the action of the drive system, the material continuously tumbles and stirs inside the drum, allowing the material to fully contact the air, accelerating the evaporation of moisture, and improving drying efficiency. At the same time, the mutual friction and collision between material particles during the tumbling process helps to break up material agglomeration, increase the specific surface area of ​​the material, further promote the growth of microorganisms and the fermentation reaction, and improve the fermentation effect and quality.

[0031] Furthermore, the fermentation drum also includes a partition plate and a spiral plate. The partition plates are multiple and are arranged at intervals along the circumference of the fermentation drum on its inner wall and close to the through hole. The spiral plate is fixedly installed on its inner wall along the circumference of the fermentation drum to guide the bedding material to the recycled bedding material outlet.

[0032] The beneficial effects of adopting the above technical solution are as follows: Multiple partition plates are arranged at intervals along the circumference of the fermentation drum on its inner wall and close to the through holes, which can divide the internal space of the fermentation drum into several relatively independent small areas. When the material enters the fermentation drum through the through holes, it is first dispersed into each small area by the partition plates. During the rolling of the fermentation drum, the material in each small area can be fully rolled and stirred, making the contact between the material and microorganisms in the air more uniform, avoiding the phenomenon of local accumulation or uneven fermentation of the material in the drum, thereby improving the uniformity and consistency of the entire fermentation process and ensuring the stable quality of the recycled bedding material; the spiral plate is fixedly installed on its inner wall along the circumference of the fermentation drum. As the fermentation drum rolls, the spiral plate can guide the material from the feed end (through hole side) to the discharge end (recycled bedding material outlet side) like a screw conveyor. This design not only ensures the smooth transport of materials within the fermentation drum, preventing excessive retention or backflow and improving material transport efficiency, but also controls the residence time of materials within the drum to a certain extent, allowing the materials to complete the drying and fermentation process within a suitable fermentation time, further enhancing the fermentation effect and the equipment's production efficiency.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] This utility model discloses a high-efficiency integrated equipment for separating and regenerating dairy cow manure bedding, including a drying fermentation box 2. The drying fermentation box 2 includes a box body and a drying fermentation component 21 installed inside it. The inlet end of the drying fermentation component 21 is arranged near the top of the box body. A recycled bedding outlet 22 is opened on one side wall of the box body corresponding to the outlet end of the drying fermentation component 21. A recycled bedding outlet cover 3 is hinged to the recycled bedding outlet 22. A solid-liquid separation box 1 is fixed to the top of the box body. The solid-liquid separation box 1 includes... The second box contains a solid-liquid separation component 11 installed inside it. The feed end of the solid-liquid separation component 11 is arranged near the top of the second box, and the discharge end is arranged near the bottom of the second box and is connected to the feed end of the drying fermentation component 21. A towing rod 12 that can be connected to a tractor is fixedly installed on the outer side wall of the second box near the recycled pad material outlet cover plate 3. A feed cylinder 4 is fixed at the top of the second box, which corresponds to the feed end of the solid-liquid separation component 11 and has a feed inlet 41 on its side wall. Multiple wheels 6 are installed at intervals on the bottom surface of the first box.

[0045] It also includes a pad material conveying unit, which includes multiple supports and a pad material conveying belt 5 installed on the supports. The supports include telescopic legs 54 and multiple fixed supports. The telescopic legs 54 are supported on the ground on one side of the corresponding box body. The upper surfaces of the multiple fixed supports form inclined surfaces and are spaced apart and installed on the outer side wall of the box body. The pad material conveying belt 5 includes a horizontal feeding section 51, an inclined conveying section 53 and a horizontal discharge section 52, which are connected and driven in sequence on the telescopic legs 54 and multiple fixed supports. The end of the horizontal discharge section 52 passes through the feed cylinder 4.

[0046] In another embodiment of this utility model, an equipment box 7 is also included. The equipment box 7 is fixedly installed on one end face of the box body away from the recycled bedding material outlet 22. The equipment box 7 is equipped with a power supply device and a controller. Through the controller in the equipment box 7, centralized control of various parts such as the solid-liquid separation component 11, the drying and fermentation component 21, and the bedding material conveyor belt 5 can be easily realized. The operator can control the start, stop, speed adjustment, and other operations of the equipment from near the equipment box 7 or through remote control, realizing the automated operation of the equipment, reducing manual intervention, and improving the level of production automation. Furthermore, since the equipment box 7 is fixedly connected to the main parts such as the drying and fermentation box 2, it is easier to operate when the equipment needs to be moved or installed as a whole, without having to consider the installation position and connection of the power supply device and controller separately, thus improving the flexibility and operability of the equipment.

[0047] Another embodiment of this utility model includes a return water tank 8, which is fixedly installed on the end face of the equipment box 7 away from the box body. The return water tank 8 has a water storage chamber inside, which is connected to a drain pipe 81 that communicates with the outside, and the drain pipe is equipped with a valve. Using the water collected in the return water tank 8 for cleaning, stirring, and other processes of the equipment can effectively reduce dependence on fresh water sources, reduce water costs during equipment operation, and improve water resource utilization efficiency. This advantage is particularly obvious in areas where water resources are relatively scarce.

[0048] In the above embodiment, a placement plate 9 is fixedly installed on the outer wall of the return water tank 8 corresponding to the telescopic outrigger, and the telescopic outrigger 54 can be placed on the placement plate 9. By setting the placement plate 9, it is convenient to release the support state of the telescopic outrigger 54 when the mobile equipment needs to be moved, and place the telescopic outrigger 54 on the placement plate 9 to provide it with placement space, thus avoiding the telescopic outrigger 54 from contacting and rubbing against the ground when moving.

[0049] In a specific embodiment of the solid-liquid separation component 11 of this utility model, the solid-liquid separation component 11 includes a auger spiral solid-liquid separation drum 111, a drive motor 112, and a liquid collection funnel 113. The auger spiral solid-liquid separation drum 111 is installed inside the second housing along a direction parallel to the top surface of the second housing. The auger spiral solid-liquid separation drum 111 is supported by multiple support rods abutting against the inner side wall of the second housing. A rotating shaft is coaxially rotated inside the auger spiral solid-liquid separation drum 111. The drive motor 112 is installed on one side of the auger spiral solid-liquid separation drum 111 and is connected to the rotating shaft for transmission. The drive motor 112 is electrically connected to a power supply device and a controller. Filter holes are evenly distributed on the circumferential wall of the auger spiral solid-liquid separation drum 111. The liquid collection funnel 113 is installed inside the second housing and located below the auger spiral solid-liquid separation drum 111. A return pipe 114 is connected to the bottom end of the liquid collection funnel 113, and the other end of the return pipe 114 is connected to a water storage chamber. The side wall of the spiral solid-liquid separation drum 111 is a filter screen layer, which enhances the solid-liquid separation effect. During the material being propelled, the liquid portion can flow out through the mesh of the filter screen layer, while the solid portion is blocked inside the spiral solid-liquid separation drum 111 and continues to be conveyed forward. The pore size of the filter screen layer can be selected according to actual needs to adapt to the separation requirements of solid materials with different particle sizes, ensuring that the separated solid material has good dryness and purity. The liquid collection funnel 113 is installed inside the solid-liquid separation box 1 and located below the spiral solid-liquid separation drum 111. Its position and shape design can effectively collect the liquid flowing out from the filter screen layer. As the liquid falls naturally under the influence of gravity, the liquid collection funnel 113 can gather the dispersed droplets into a stream and guide it to the bottom of the funnel, thereby achieving centralized collection of the liquid and preventing it from flowing around in the solid-liquid separation tank 1. This improves the efficiency and cleanliness of liquid collection. Furthermore, the collected liquid is transported to the water storage chamber of the return water tank 8 through the return pipe 114. In this way, the separated liquid can be effectively recycled and reused, reducing dependence on fresh water sources, lowering equipment operating costs, reducing wastewater discharge, and improving the resource utilization efficiency and sustainability of the entire equipment system.

[0050] In the above embodiments, the solid-liquid separation assembly 11 further includes a solid-liquid separation degree adjustment assembly 115. The solid-liquid separation degree adjustment assembly 115 includes an installation sleeve 1151, a screw 1153, a conical plug 1152, and a rotating handle 1154. The installation sleeve 1151 is coaxially arranged with the auger spiral solid-liquid separation drum 111, and one end of the sleeve is fixed to the inner side wall of the housing. The other end of the sleeve is spaced apart from the discharge port of the auger spiral solid-liquid separation drum 111. The screw 1153 is coaxially installed in the installation sleeve 1151 and can move along its axial direction. The conical tip of the conical plug 1152 is arranged facing the discharge port of the auger spiral solid-liquid separation drum 111, and its flat end is fixedly connected to one end of the screw 1153. The other end of the screw 1153 passes through the side wall of the housing. The rotating handle 1154 is located on the outside of the housing and is fixedly connected to the other end of the screw 1153. By rotating the screw 1153 via the handle 1154, the conical plug 1152 can slide on the outside of the mounting sleeve 1151, thereby achieving precise adjustment of the discharge port size of the spiral solid-liquid separator 111. When it is necessary to reduce the discharge rate, the conical plug 1152 can be pushed towards the discharge port, causing its cone tip to penetrate deeper into the discharge port and reducing the cross-sectional area of ​​the discharge port; conversely, if it is necessary to increase the discharge rate, the conical plug 1152 can be pulled outward to enlarge the discharge port. This flexible adjustment method can adjust the discharge speed and quantity in real time according to actual production needs and material characteristics, ensuring that the equipment's operating efficiency and separation effect reach the optimal state.

[0051] In the above embodiment, the solid-liquid separation degree adjustment component 115 also includes a limiting rod 1155. The limiting rod 1155 is located on the outside of the housing and the vertical screw 1153 is fixedly installed on its outer side wall. A travel distance of the screw 1153 is reserved between the limiting rod 1155 and the outer side wall of the housing. The limiting rod 1155 is vertically fixed on the outer wall of the screw 1153, and the limiting rod 1155 is spaced apart from the side wall of the solid-liquid separation tank 1. When the handle 1154 rotates the screw 1153, the limiting rod 1155 will rotate together with the screw 1153. By reasonably designing the relative position and spacing between the limiting rod 1155 and the side wall of the solid-liquid separation tank 1, and setting a specific length of the installation sleeve 1151, the rotation range of the screw 1153 can be effectively limited. This prevents the screw 1153 from rotating excessively due to improper operation or negligence during the adjustment process, which would cause the conical plug 1152 to extend excessively into or move excessively away from the discharge port of the auger spiral solid-liquid separation drum 11, resulting in problems such as the discharge port being completely blocked or the discharge volume not being effectively adjusted. This ensures that the solid-liquid separation degree adjustment component can work normally and reliably.

[0052] In another embodiment of this utility model, the drying fermentation box 2 further includes a conveying assembly 23. The conveying assembly 23 includes a feeding plate 231, a main shaft 232, a spiral blade 233, and a second drive motor 234. A material transfer chamber is provided in the box body corresponding to the discharge port of the solid-liquid separation assembly 11. The top of the material transfer chamber is open, and a through hole communicating with the feed end of the drying fermentation assembly 21 is formed on its side wall. The feeding plate 231 is fixed to the bottom wall corresponding to the through hole and has a preset tilt angle. The main shaft 232 is arranged along the direction of the top opening of the material transfer chamber and passes through the feeding plate 231. The spiral blade 233 is fixed around the outer wall of the main shaft 232 and located above the feeding plate 231. The second drive motor 234 is located below the feeding plate 231, and its driving end is connected to the main shaft 232. The second drive motor 234 is electrically connected to a power supply device and a controller. The combination of the tilt angle of the feeding plate 231 and the pushing action of the spiral blade 233 effectively prevents excessive accumulation of material in the material transfer chamber. Once the material enters the conveying chamber, it will move forward rapidly under the guidance of the feeding plate 231 and the push of the spiral blades 233, reducing the residence time of the material in the conveying chamber, reducing the risk of uneven fermentation and equipment blockage caused by material accumulation, and ensuring the continuity and uniformity of the material conveying process.

[0053] In addition, a material collection funnel is provided inside the solid-liquid separation box 1 at the top opening of the material transfer chamber corresponding to the conveying component 23. The opening of the material collection funnel is arranged below the discharge port of the auger spiral solid-liquid separation drum 111. It can collect the material discharged from the auger spiral solid-liquid separation drum 111 and let it leak into the material transfer chamber. Then, the material transfer chamber is conveyed by the conveying component to the inlet of the drying fermentation component for the drying step.

[0054] In a specific embodiment of the drying and fermentation assembly of this utility model, the drying and fermentation assembly 21 includes a fermentation drum 211, a drive motor 212, a drive gear 213, a driven gear 214, and a drive rack 215. The fermentation drum 211 is arranged axially along the recycled material outlet 22, with one end away from the recycled material outlet 22 communicating with a through hole. The drive motor 212 is located at the bottom of the housing and is electrically connected to a power supply device and a controller. The drive gear 213 is mounted at both ends of the drive motor 212 via a drive shaft along the axial direction of the fermentation drum 211. The driven gear 214 is rotatably mounted at the top of the housing via a shaft and is arranged radially along the fermentation drum 211 corresponding to the drive gear 213. The drive rack 215 is sleeved and fixed on the outer peripheral wall of the fermentation drum 211 and can mesh with the drive gear 213 and the driven gear 214 for transmission. The fermentation drum 211 is arranged axially along the recycled material outlet 22, and its internal space communicates with the through hole, providing a closed fermentation environment with a large volume for the material. As the fermentation drum 211 rotates under the action of the drive system, the material continuously tumbles and agitates inside the drum, ensuring full contact between the material and air, accelerating moisture evaporation, and improving drying efficiency. Simultaneously, the friction and collision between material particles during tumbling helps break up material agglomerates, increases the specific surface area of ​​the material, further promotes microbial growth and fermentation reactions, and improves fermentation effect and quality.

[0055] In addition, the two shafts that pass through and connect the drive gear 213 and the driven gear 214 are fixedly mounted on the inner wall of the drying fermentation tank 2 by bearings to improve their support force on the fermentation drum 211 and improve the stability of the equipment operation.

[0056] In the above embodiment, the fermentation drum 211 further includes partition plates 2111 and spiral plates 2112. Multiple partition plates 2111 are arranged at intervals along the circumference of the fermentation drum 211 on its inner wall and near the through holes. The spiral plates 2112 are fixedly installed along the circumference of the fermentation drum 211 on its inner wall to guide the bedding material to the recycled bedding material outlet 22. The multiple partition plates, arranged at intervals along the circumference of the fermentation drum on its inner wall and near the through holes, can divide the internal space of the fermentation drum into several relatively independent small areas. When the material enters the fermentation drum 211 through the through holes, it is first dispersed into each small area by the partition plates 2111. During the rotation of the fermentation drum 211, the material in each small area is fully tumbled and stirred, resulting in more uniform contact between the material and airborne microorganisms. This prevents localized accumulation or uneven fermentation within the drum, thereby improving the uniformity and consistency of the entire fermentation process and ensuring stable quality of the recycled bedding material. The spiral plate 2112 is fixedly installed along the circumference of the fermentation drum 211 on its inner wall. As the drum rotates, the spiral plate 2112 guides the material from the feed end through-hole side to the discharge end recycled bedding material outlet side, much like a screw conveyor. This design not only ensures smooth material transport within the fermentation drum 211, preventing excessive retention or backflow and improving transport efficiency, but also controls the residence time of the material within the drum to a certain extent, allowing the material to complete the drying and fermentation process within a suitable timeframe, further enhancing the fermentation effect and equipment production efficiency.

[0057] The working principle of this high-efficiency integrated dairy cow manure bedding separation and regeneration equipment is as follows:

[0058] The integrated equipment is towed by a tractor to the vicinity of the cattle shed area where the bedding needs to be replaced. Afterwards, the tractor is disconnected, the recycled bedding outlet cover is opened, and the telescopic outriggers of the conveyor belt are rotated so that their bottom ends are supported on the ground, completing the temporary fixing process of the integrated equipment. Then, the manure bedding recycling process can begin. The manure bedding is conveyed by the conveyor belt into the feed cylinder, and then enters the solid-liquid separation tank. The solid-liquid separation component performs solid-liquid separation on the manure bedding, specifically through a auger spiral solid-liquid separation drum. The material is conveyed by rotating a handle to adjust the opening size of the auger spiral solid-liquid separation drum, thereby adjusting the internal compression pressure on the material and controlling its moisture content. Liquid is discharged from the filter layer on the side wall of the auger spiral solid-liquid separation drum into a liquid collection funnel, and then flows through a return pipe to a return water tank for recycling. The solid bedding material after solid-liquid separation is further conveyed to the conveying assembly, which then quickly conveys it to the fermentation drum for drying, completing the bedding material regeneration process. Finally, the regenerated bedding material is discharged from the regenerated bedding material outlet. After completing the bedding material regeneration task in this area, the regenerated bedding material outlet cover can be closed, the tow bar connected to the towing vehicle, and the material transported to the next target area to complete the regenerated bedding material task in the next area.

[0059] Therefore, this high-efficiency integrated dairy cow manure bedding separation and recycling equipment can be moved by traction according to usage, which facilitates the bedding recycling process, reduces the time cost of reciprocating bedding transportation, and improves the recycling efficiency of bedding.
