Description

Technical Field

[0001] This invention belongs to the technical field of dairy farming, specifically, it relates to a constant-temperature dairy farming system that utilizes manure fermentation to generate heat. Background Technology

[0002] In dairy farming, temperature has a significant impact on milk production, especially in the cold winters of northern regions. To prevent this impact, current methods involve heating the barns to maintain a temperature between 15-23°C. Most methods involve installing heaters or air conditioners in the barns or sheds. However, the main drawback of these methods is their high energy consumption, leading to higher farming costs. Therefore, there is an urgent need for a dairy farming system that utilizes the heat generated from fermented cow manure to heat the barns or sheds, improving waste utilization, reducing heating costs, and ensuring that milk production is not negatively affected by low temperatures. Summary of the Invention

[0003] This invention provides a constant-temperature dairy farming system that utilizes manure fermentation to generate heat, thereby improving waste utilization, reducing heating costs, and ensuring that the milk production of dairy cows is not affected by low-temperature environments.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A constant-temperature dairy farming system utilizing manure fermentation for heat generation includes a manure fermentation chamber located at the bottom of the cowshed. A conduit system is installed within the manure fermentation chamber, and a scraper is installed at the upper end of the chamber. The scraper moves along the length of the cowshed via a transmission chain. The manure fermentation chamber is filled with manure mixed with aerobic bacteria, which is then turned over and mixed by a turning mechanism extending into the chamber. Multiple manure collection troughs are spaced apart along the length of the cowshed at the upper end of the fermentation chamber. Each collection trough is embedded in the upper part of the fermentation chamber and is isolated from it. The upper ends of the collection troughs are covered by movable covers, which are flush with the upper end of the fermentation chamber.

[0006] Furthermore, the cow manure fermentation chamber includes a lower insulation layer and an upper breeding layer, forming a fermentation cavity between the lower insulation layer and the upper breeding layer. The cow manure to be fermented is filled into the fermentation cavity, and when the movable cover plate seals the manure collection trough, the movable cover plate is flush with the upper breeding layer.

[0007] Furthermore, multiple fermentation heat release zones are spaced apart along the length of the cattle shed within the fermentation chamber, and the manure collection trough is formed between adjacent fermentation heat release zones; the guiding pipe system includes multiple pipes with guiding holes on their surfaces, which extend laterally into the corresponding fermentation heat release zones along the cattle shed, and the ends of these pipes on the same side are interconnected; multiple heat conduction channels are constructed on the partition separating the manure collection trough and the fermentation heat release zones, and these heat conduction channels are spaced apart along the vertical direction, with the manure collection trough extending from the upper end to the lower end of the fermentation chamber; the turning mechanism includes an auger conveyor slidably installed on the crossbeam of the cattle shed, the auger conveyor being vertically arranged, with its inlet extending to the bottom of the fermentation heat release zone and its outlet located at the upper part of the fermentation heat release zone.

[0008] Furthermore, multiple assembly areas are spaced apart along the length of the cattle shed within the fermentation chamber, and manure collection troughs are formed between adjacent assembly areas. Each assembly area extends laterally along the cattle shed, and multiple fermentation heat release boxes spaced apart along the length of the assembly area are assembled within each assembly area. Each fermentation heat release box is filled with cow manure to be fermented.

[0009] Furthermore, an isolation net is constructed at the lower part of the fermentation heat release box, and a discharge port is opened at the bottom of the fermentation heat release box. The discharge port is sealed by a stopcock. A first turntable is rotatably connected to the bottom of the fermentation heat release box, and a second turntable is rotatably connected to the isolation net. The conductive pipe system includes multiple vertical pipes that pass through the first turntable and the second turntable sequentially from the lower end of the fermentation heat release box and extend into the fermentation heat release box. Each vertical pipe is covered with holes, and the lower ends of the vertical pipes are interconnected through multiple bottom pipes. These bottom pipes are all connected to a first connector pipe, and the first connector pipe is rotatably connected to a second connector pipe on the main conductive pipe. The material turning mechanism consists of a first connector pipe, bottom pipes, and vertical pipes. A sprocket is installed on the first connector pipe, and the sprocket drives the first connector pipe to rotate through a drive chain, so that each vertical pipe is agitated in the fermentation heat release box.

[0010] Furthermore, the upper breeding layer is divided into multiple panels along the length of the cattle shed. The movable cover plate is integrally formed with the corresponding panel to form a flip plate. Lifting cylinders are hinged to both sides of the flip plate. The flip plate is flipped up by the lifting cylinders to expose the corresponding manure collection trough and fermentation chamber.

[0011] Furthermore, the conduit system includes multiple installation pipes arranged at intervals along the transverse direction of the cow dung fermentation chamber and located at the bottom of the cow shed. Each installation pipe extends along the length of the cow shed and is covered with holes. The turning mechanism extends laterally to both sides of the cow dung fermentation chamber, and both ends of the turning mechanism are detachably connected to two transmission chains, and the transmission chains are detachably connected to the corresponding sides of the manure scraper.

[0012] Furthermore, the turning mechanism includes a cage-like structure formed by multiple connecting rods, each connecting rod extending laterally along the cow dung fermentation chamber, with stirring blades spaced axially on each connecting rod; radial adjustment components are respectively provided at both ends of the cage-like structure, and the connecting rods are adjusted to move closer to each other through the radial adjustment components, so that the stirring blades on adjacent connecting rods are connected to each other and form a spiral feeding blade, the spiral feeding blade extending spirally along the axial direction of the cage-like structure; each radial adjustment component is connected to the output shaft of a corresponding power motor, each power motor is connected to a mounting base, and a telescopic component is connected to the mounting base, the end of the telescopic component away from the mounting base being connected to the corresponding side of the upper end of the cow dung fermentation chamber through a transmission component, and the transmission component is mounted on a fixed base, the fixed base being detachably connected to the transmission chain.

[0013] Furthermore, the radial adjustment assembly includes an adjustment disc, the connecting rods are evenly arranged along the circumference of the adjustment disc, and a plurality of strip-shaped adjustment holes are evenly arranged along the circumference of the adjustment disc. Each strip-shaped adjustment hole extends radially along the adjustment disc, and the end of the connecting rod extends out of the adjustment disc through the strip-shaped adjustment hole. Two locking nuts are threadedly connected to the end of the connecting rod, and the two locking nuts are locked at the two end faces of the adjustment disc.

[0014] Furthermore, the radial adjustment assembly includes a connecting sleeve connected to the output shaft of the power motor, and a plurality of hinge rods are evenly hinged to the connecting sleeve along its circumference, with the end of each hinge rod away from the connecting sleeve hinged to a corresponding connecting rod; the power motor is laterally slidably mounted on the mounting base, and a lateral drive member is provided between the mounting base and the power motor.

[0015] The present invention, by employing the aforementioned structure, achieves the following technological advancements compared to existing technologies: The present invention fills a cow manure fermentation chamber with cow manure to be fermented or in a fermenting state, mixed with aerobic bacteria and other fermenting bacteria. The cow manure ferments and releases heat, which heats the cowshed or barn, raising the temperature inside. When the ambient temperature is low, the cow manure fermentation chamber can be heated through a conduit system, promoting fermentation and allowing heat to gradually diffuse into the cowshed or barn, maintaining a suitable temperature. During fermentation, the gas produced by fermentation is expelled from the fermentation chamber through the conduit system, and the chamber can be humidified when humidity is too low. The manure collection trough in this invention is used to collect cow manure from the floor of the cowshed or barn. The manure is scraped into a collection trough by a scraper, and then the trough is covered. The heat generated by the fermentation of the manure in the fermentation chamber heats the fresh manure in the collection trough, causing it to gradually dehydrate. This facilitates subsequent collection and processing, allowing the collected manure to be used for fermentation and heat release. Furthermore, once the manure in the fermentation chamber is fully fermented, it can be used as fertilizer for crops and vegetables, or dried and further processed to be used as bedding for cattle, thus making full use of the manure. To ensure complete fermentation, the manure in the fermentation chamber is turned over by a turning mechanism after a period of fermentation, improving the fermentation effect. In summary, this invention utilizes the heat generated by the fermentation of manure to heat cattle sheds or barns, thereby improving waste utilization, reducing heating costs, and ensuring that the milk production of dairy cows is not affected by low temperatures.

Detailed Implementation

[0037] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0038] This invention discloses a constant-temperature dairy farming system that utilizes manure fermentation to generate heat, such as... Figure 1-18As shown, the system includes a pre-built cattle shed or barn, with a cow manure fermentation layer 200 at the bottom. The cow manure fermentation layer 200 has a cow manure fermentation chamber 205, in which a conduit system is installed. A manure scraper 600 is installed at the top of the cow manure fermentation chamber 205. The manure scraper 600 is detachably connected to a transmission chain 700, and the manure scraper 600 moves along the length of the cattle shed through the transmission chain 700, thereby scraping away the cow manure on the ground of the cattle shed or barn. In this invention, a cow manure fermentation chamber 205 is filled with cow manure to be fermented. The cow manure to be fermented contains aerobic bacteria. The cow manure to be fermented is turned up and mixed by a turning mechanism that extends into the cow manure fermentation chamber 205. Depending on the arrangement of the cow manure fermentation layer 200 or the cow manure fermentation chamber 205, different turning mechanisms and different conduit systems are selected. The turning mechanisms of this invention are divided into turning mechanism A, turning mechanism B and turning mechanism C300, and the conduit systems are divided into conduit system A, conduit system B209 and conduit system C. The present invention provides a plurality of manure collection troughs 202 at the upper end of the cow manure fermentation chamber 205. These manure collection troughs 202 are spaced apart along the length of the cow shed. Each manure collection trough 202 is embedded in the upper part of the fermentation chamber and is isolated from the fermentation chamber and is not connected to it. The upper end of the manure collection trough 202 is covered by a movable cover plate, which is flush with the upper end of the cow manure fermentation chamber 205. When it is necessary to scrape cow manure into the manure collection trough 202, the movable cover plate needs to be opened.The working principle and advantages of this invention are as follows: This invention fills the cow manure fermentation chamber 205 with mixed aerobic bacteria and other fermenting bacteria, either to be fermented or in a fermenting state. The cow manure ferments and releases heat, which heats the cowshed or barn, raising the temperature inside. When the ambient temperature is low, the cow manure fermentation chamber 205 can be heated through a conduit system, promoting fermentation and allowing heat to gradually diffuse into the cowshed or barn, resulting in a suitable temperature. During fermentation, the gases produced by fermentation are discharged from the cow manure fermentation chamber 205 through the conduit system. Furthermore, when the humidity in the cow manure fermentation chamber 205 is too low, it can be humidified through the conduit system. The manure collection trough 202 is used to collect cow manure from the ground of the cowshed or barn, where it is scraped by a scraper 600. The manure is placed into the manure collection trough 202 and then covered. The heat generated by the fermentation of the manure in the manure fermentation chamber 205 heats the fresh manure in the manure collection trough 202, causing the fresh manure to gradually dehydrate. This facilitates subsequent collection and processing, allowing the collected manure to be used for fermentation and heat release. Furthermore, after complete fermentation, the manure in the manure fermentation chamber 205 can be used as fertilizer for crops and vegetables, or dried and further processed to be used as bedding for cattle, thus fully utilizing the manure. To ensure complete fermentation, after a period of fermentation, the manure in the manure fermentation chamber 205 is turned over by a turning mechanism to improve the fermentation effect. In summary, this invention utilizes the heat generated by manure fermentation to heat cattle sheds or barns, thereby improving waste utilization, reducing heating costs, and ensuring that the milk production of dairy cows is not affected by low temperatures.

[0039] As a preferred embodiment of the present invention, such as Figure 4 , 6 As shown, the cow manure fermentation chamber 205 includes a lower insulation layer 207 and an upper breeding layer 206. A fermentation cavity is formed between the lower insulation layer 207 and the upper breeding layer 206. When the cow manure to be fermented is filled into the fermentation cavity and the movable cover plate seals the manure collection trough 202, the movable cover plate is flush with the upper breeding layer 206.

[0040] As a preferred embodiment of the present invention, such as Figure 1-2As shown, multiple fermentation heat release zones 201 are spaced apart along the length of the cattle shed within the fermentation chamber, and the aforementioned manure collection troughs 202 are formed between adjacent fermentation heat release zones 201. The conduit system is a conduit system A, which includes multiple pipes 204 with perforations on their surfaces. These pipes 204 extend laterally into the corresponding fermentation heat release zones 201 within the cattle shed. One end of each pipe 204 is interconnected via a conduit, and the other ends are interconnected via another conduit. Air or humidifying water enters each pipe 204 through one conduit, injecting air or water into the fermentation heat release zones 201. Excess air and water are discharged through the other conduit. When no air or water is added, the gas produced during fermentation is discharged through the pipes 204 and the two conduits. In this embodiment, the manure collection trough 202 and the fermentation heat release zone 201 are separated by a partition 203. The partition 203 includes a partition body 2031 on which multiple heat-conducting channels 2032 are constructed. These heat-conducting channels 2032 are spaced vertically. Furthermore, in this embodiment, the manure collection trough 202 extends from the upper end to the lower end of the fermentation chamber, allowing it to collect more manure and increasing the contact area between the manure and the partition body 2031, thus promoting the drying and dehydration of the manure. For this fermentation chamber configuration, this embodiment uses a turning mechanism A, such as... Figure 3 As shown, the turning mechanism A includes an auger conveyor 400, which is slidably mounted on the crossbeams 500 of the cowshed. There are multiple crossbeams 500, each corresponding to a fermentation and heat release zone 201. Thus, after turning over one fermentation and heat release zone 201, the auger conveyor 400 is transferred to another crossbeam 500 to turn over the remaining fermentation and heat release zones 201. In this embodiment, the auger conveyor 400 is vertically positioned, with its inlet extending to the bottom of the fermentation and heat release zone 201 and its outlet located at the top. This allows the auger conveyor 400 to transfer cow manure from the lower part of the fermentation and heat release zone 201 to the upper part, achieving the purpose of turning over the manure from top to bottom. This results in more uniform turning and mixing, promoting complete fermentation of the cow manure.

[0041] As a preferred embodiment of the present invention, such as Figure 5-10As shown, multiple assembly areas are arranged within the fermentation chamber, spaced apart along the length of the cattle shed. The aforementioned manure collection troughs 202 are formed between adjacent assembly areas, and each assembly area extends laterally along the cattle shed. Multiple fermentation heat release boxes 208 are assembled within each assembly area, spaced apart along the length of the assembly area. Each fermentation heat release box 208 is filled with cow manure to be fermented. In this embodiment, when the fermentation heat release box 208 needs to be replaced after use, the fermented fermentation heat release box 208 can be removed or lifted out using a lifting tool. Then, a new fermentation heat release box 208 containing cow manure to be fermented is placed in its place. The cow manure in the removed fermentation heat release box 208 is removed for later use, and the new cow manure to be fermented is then filled into the fermentation heat release box 208. The fermentation heat release box 208 of this embodiment includes a box body 2081, and a box cover 2088 is detachably connected to the upper end of the box body 2081. A handle 2089 is provided on the box cover 2088. In order to avoid the handle 2089 interfering with the upper culture layer 206 and causing the upper culture layer 206 to be uneven, the measure taken is to construct a support groove on the upper surface of the box cover 2088, and the handle 2089 is installed in the support groove. In this embodiment, an isolation net 2083 is constructed at the lower part of the fermentation heat release box 208. A receiving cavity 2082 is formed above the isolation net 2083, which is used to fill cow dung. A water collection cavity 2085 is formed at the lower part of the isolation net 2083, which is used to collect liquid seeping from the cow dung. A discharge port is provided at the bottom of the fermentation heat release box 208, which is sealed by a stopcock 2087. In this embodiment, a first turntable 2086 is rotatably connected to the bottom of the fermentation heat release box 208, and a second turntable 2084 is rotatably connected to the isolation net 2083. In this embodiment, the conduit system is a conduit system B209, which includes multiple vertical pipes 2096. These vertical pipes 2096 pass sequentially from the lower end of the fermentation heat release box 208, through the first turntable 2086 and the second turntable 2084, and extend into the fermentation heat release box 208. Each vertical pipe 2096 is covered with holes, and to facilitate the smooth insertion of the vertical pipes 2096 into the fermentation heat release box 208 during the process of descending, each vertical pipe 2096 has a pointed head 2097 at its upper end. In this embodiment, the lower ends of these vertical pipes 2096 are interconnected through multiple bottom pipes 2095. These bottom pipes 2095 are all connected to the first connector pipe 2093, which is rotatably connected to the second connector pipe 2092 on the main conduit pipe 2091.The turning mechanism in this embodiment is turning mechanism B, which consists of a first connecting pipe 2093, a bottom pipe 2095, and a vertical pipe 2096. A sprocket 2094 is installed on the first connecting pipe 2093. The sprocket 2094 drives the first connecting pipe 2093 to rotate through a driving chain, thereby causing each vertical pipe 2096 to be stirred in the fermentation heat release box 208. That is, the sprocket 2094 drives the first connecting pipe 2093 to rotate, so that the first connecting pipe 2093 drives the vertical pipe 2096 to rotate through the bottom pipe 2095. In this way, the vertical pipe 2096 makes a circular motion around the first connecting pipe 2093 as the axis, thereby realizing the stirring of cow manure in the receiving cavity 2082.

[0042] As a preferred embodiment of the present invention, such as Figure 4 As shown, the upper breeding layer 206 is divided into multiple panels along the length of the cattle shed. The aforementioned movable cover plate is integrally formed with the corresponding panel to form a flap. Lifting cylinders 210 are hinged on both sides of the flap. The flap is lifted by the lifting cylinders 210, thus exposing the corresponding manure collection trough 202 and fermentation chamber. The manure scraper 600 is driven to scrape the cow manure into the corresponding manure collection trough 202.

[0043] As a preferred embodiment of the present invention, such as Figure 11-13 As shown, the conduit system is conduit system C, which includes multiple installation pipes 211. These installation pipes 211 are located at the bottom of the cow manure fermentation chamber 205 and are spaced laterally along the cowshed. Each installation pipe 211 extends along the length of the cowshed and is covered with holes for the flow of gas and water. In this embodiment, the turning mechanism is a turning mechanism C300. The turning mechanism C300 extends laterally to both sides of the cow manure fermentation chamber 205, and both ends of the turning mechanism C300 are detachably connected to two drive chains 700, and the drive chains 700 are detachably connected to the corresponding sides of the manure scraper 600. In this embodiment, during the movement of the turning mechanism C300 driven by the transmission chain 700, the turning mechanism C300 turns the cow manure in the cow manure fermentation chamber 205. Moreover, during the movement of the turning mechanism C300 in the cow manure fermentation chamber 205, there are no other auxiliary parts in the cow manure fermentation chamber 205 that interfere with its movement.

[0044] As a preferred embodiment of the present invention, such as Figure 12-14As shown, the turning mechanism C300 includes a cage-like structure formed by multiple connecting rods 301. Each connecting rod 301 extends laterally along the cow dung fermentation chamber 205, and stirring blades 302 are spaced apart along its axial direction on each connecting rod 301. In this embodiment, radial adjustment components are respectively provided at both ends of the cage-like structure, and the connecting rods 301 are brought closer to each other through the adjustment of the radial adjustment components, thereby forming a spiral feeding blade on the adjacent connecting rods 301. The spiral feeding blade extends spirally along the axial direction of the cage-like structure. When the stirring blades 302 form a spiral feeding blade, it is used to transfer cow dung from one end of the cow dung fermentation chamber 205 to the other end, or to discharge fully fermented cow dung from the cow dung fermentation chamber 205, or to gradually transport cow dung to be fermented into the cow dung fermentation chamber 205. When the stirring blades 302 are staggered (in a non-continuous state), the turning range can be adjusted by adjusting the spacing of the connecting rods 301. Furthermore, during the rotation and parallel movement of the cage structure, the non-continuous stirring blades 302 stir and turn the cow manure in the cow manure fermentation chamber 205, thereby promoting the fermentation and heat release of the cow manure. In this embodiment, each radial adjustment component is connected to the output shaft of the corresponding power motor 307. Each power motor 307 is connected to the mounting base 308. A telescopic component 310 is connected to the mounting base 308. This telescopic component 310 is generally an electric cylinder. The end of the telescopic component 310 away from the mounting base 308 is connected to the corresponding side of the upper end of the cow manure fermentation chamber 205 via a transmission component. The transmission component is mounted on a fixed base 309, which is detachably connected to the transmission chain 700. The transmission assembly includes two rows of gears 311 rotatably mounted on the fixed base 309. Guide rails are constructed on both sides of the upper end of the cow dung fermentation chamber 205. The two rows of gears 311 are assembled in the guide rails, and each row of gears 311 meshes with the corresponding side of the guide rail. As the fixed base 309 moves with the transmission chain 700, the gears 311 move along the guide rails.

[0045] As a preferred embodiment of the present invention, the radial adjustment component is implemented in two ways. The first type of radial adjustment component is as follows: Figure 15As shown, the radial adjustment assembly includes an adjustment disk 303. The output shaft of the power motor 307 is connected to the center of the adjustment disk 303 via a transmission rod 306. The connecting rods 301 are evenly arranged along the circumference of the adjustment disk 303. Multiple strip-shaped adjustment holes 304 are evenly arranged along the circumference of the adjustment disk 303, each extending radially. In this embodiment, the end of the connecting rod 301 passes through the strip-shaped adjustment hole 304 and extends out of the adjustment disk 303. Two locking nuts 305 are threaded to the end of each connecting rod 301, and these two locking nuts 305 are locked at both end faces of the adjustment disk 303. In this embodiment, by loosening the locking nut 305, the connecting rod 301 and the adjusting plate 303 are unlocked. Then, the position of the connecting rod 301 at the corresponding strip-shaped adjusting hole 304 is adjusted, and the locking nut 305 is tightened again to fix the connecting rod 301 and the adjusting plate 303. This changes the diameter of the cage-like structure, adjusting the material turning range. Alternatively, the stirring blades 302 can be connected to achieve material feeding and discharging, depending on the specific situation. The second type of radial adjustment component is as follows: Figure 16-17 As shown, the radial adjustment assembly includes a connecting sleeve 318, which is fixedly connected to the transmission rod 306. The output shaft of the power motor 307 is connected to the transmission rod 306. Multiple hinge rods 319 are evenly hinged along the circumference of the connecting sleeve 318. The end of each hinge rod 319 away from the connecting sleeve 318 is hinged to the corresponding connecting rod 301. In this embodiment, the power motor 307 is laterally slidably mounted on the mounting base 308. A lateral drive member 312 is provided between the mounting base 308 and the power motor 307. This lateral drive member 312 is an electric cylinder. In this embodiment, the lateral position of the power motor 307 is adjusted by the lateral drive member 312, thereby causing the power motor 307 to drive the hinge rods 319 to move through the transmission rod 306. This causes the hinge rods 319 to move the connecting rods 301 closer or further apart, thereby adjusting the material turning range. In this embodiment, when feeding the cow dung fermentation chamber 205, an outer cover 313 is detachably installed outside the cage-like structure. The outer cover 313 is open on one side facing the feeding area. The feeding end of the outer cover 313 is constructed with a feeding end cover 316, and the other end of the outer cover 313 is constructed with a blocking cover 317. Plate-shaped upper edge 315 and plate-shaped lower edge 314 are respectively constructed at the upper and lower ends of the outer cover 313. New cow dung to be fermented enters the cage-like structure through the feeding end cover 316. Since the stirring blades 302 on the cage-like structure are connected to each other and form a spiral feeding blade, the cow dung to be fermented is transported by the spiral feeding blade and gradually enters the cow dung fermentation chamber 205 from the opening of the outer cover 313, thereby realizing the feeding of the cow dung fermentation chamber 205.
