Description

Technical Field

[0001] This application relates to the field of cow manure fermentation technology, and in particular to a manure treatment device for ecological cattle breeding. Background Technology

[0002] With the promotion of ecological farming models, the treatment of manure from large-scale cattle farms has become a challenge. Directly piling up cattle manure easily leads to environmental pollution and resource waste. One approach is to mix the manure produced during farming with straw, sawdust, etc., and pile it up, turning it regularly and adding water. This allows microorganisms to decompose the organic matter, and the high temperatures generated during fermentation can kill pathogens and insect eggs, ultimately converting the manure into organic fertilizer for waste utilization. However, this method still has significant drawbacks: the fermentation cycle is as long as 2-3 months, and during this period, it is necessary to manually turn the pile multiple times to regulate oxygen, temperature, and humidity. The repeated turning during fermentation consumes a lot of manpower and reduces the efficiency of fertilizer fermentation. Summary of the Invention

Detailed Implementation

[0029] This application discloses a manure treatment device for ecological cattle breeding. With the setting of the stirring component 4, when the stirring component 4 is raised and lowered, the linkage gear 402 therein will cooperate with the fixed tooth plate 407, so that the linkage gear 402 rotates, thereby driving the outer sleeve 401 and the stirring plate 406 to rotate around the axis of the outer sleeve 401, thereby stirring the cow manure fermenting inside the fermentation tank 1, so that the cow manure can be evenly mixed with sawdust or straw, improving the quality of fertilizer formation.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example 1:

[0032] Reference Figure 1 , Figure 4 and Figure 5This application discloses a manure treatment device for ecological cattle farming, including a mixing assembly 4. The mixing assembly 4 is connected to a lifting ring 207 via a support frame structure 3. The mixing assembly 4 includes an outer sleeve 401, a fixed bevel gear 403, and a linkage bevel gear 405. The linkage bevel gear 405 is symmetrically meshed with the outer side of the fixed bevel gear 403. The two ends of the outer sleeve 401 are provided with end-connecting fixed posts 303. The fixed bevel gear 403 is connected to two fixed connecting rods 404. The outer sleeve 401 is fixedly connected to the fixed column 303. A linkage gear 402 is fixedly installed at one end of the outer sleeve 401. The linkage gear 402 is rotatably installed at the other end of the fixed column 303. A fixed tooth plate 407 is meshed on the outer side of the linkage gear 402. A stirring plate 406 is fixedly installed at the far ends of the linkage bevel gears 405. The linkage bevel gears 405 are rotatably installed on the inner side of the outer sleeve 401. The fixed bevel gear 403 is fixedly installed inside the outer sleeve 401.

[0033] When the mixing assembly 4 is raised and lowered, the linkage gear 402 meshes with the fixed toothed plate 407 and rotates. The rotation of the linkage gear 402 drives the outer sleeve 401 to rotate, which in turn drives the linkage bevel gear 405 and the mixing plate 406 to move around the axis of the outer sleeve 401, thus performing the mixing of materials. Since the fixed bevel gear 403 is stationary, the linkage bevel gear 405 rotates on its own axis when it moves around the outside of the fixed bevel gear 403. This causes the mixing plate 406 to rotate on its own axis while moving around the fixed bevel gear 403, thus turning the material over and turning the waste material at the bottom upwards. This effectively dissipates excess heat, improves fermentation quality, reduces manual intervention, and improves the efficiency of turning the material.

[0034] It should be noted that the outer sleeve 401 is rotatably mounted at one end of the end-connecting fixed column 303, the fixed connecting tooth plate 407 is fixedly mounted on the outside of the top outer rotating cylinder 203 and the bottom outer rotating cylinder 208, and the fixed connecting rod 404 is mounted through the outer sleeve 401.

[0035] In this way, the outer sleeve 401 can rotate, while the fixed connecting rod 404 is fixed, which facilitates the mixing plate 406 to perform the work of turning and mixing materials.

[0036] Reference Figure 1 and Figure 3 It also includes a lifting screw 205, with fixed columns 204 at both ends of the lifting screw 205. The fixed columns 204 pass through and are fixedly installed at the bottom of the inner side of the fermentation cylinder 1. A lifting ring 207 is threadedly connected to the outer side of the lifting screw 205.

[0037] Since the fixed column 204 and the lifting screw 205 are stationary, the lifting ring 207 will rise or fall when the lifting screw 205 rotates outside, thereby driving the mixing component 4 to mix and turn the cow dung mixture.

[0038] Reference Figure 1 and Figure 3 A drive gear 201 is fixedly installed at the drive end of the servo motor 2. The drive gear 201 is rotatably installed at the top end of the top end cover 101. A driven gear 202 is meshed on the outer side of the drive gear 201. A top outer rotating cylinder 203 is fixedly installed at the bottom end of the driven gear 202. The top outer rotating cylinder 203 passes through and is rotatably installed at the top end of the top end cover 101. A plurality of fixed sliding rods 206 are fixedly installed at the bottom end of the top outer rotating cylinder 203. The fixed sliding rods 206 pass through the lifting connecting ring 207 and are slidably connected to it. A bottom outer rotating cylinder 208 is fixedly installed at the other end of the fixed sliding rod 206. The bottom outer rotating cylinder 208 is rotatably installed at the bottom inner side of the fermentation cylinder 1.

[0039] Start the servo motor 2, which drives the drive gear 201 to rotate. The rotation of the drive gear 201 drives the driven gear 202 to rotate as well. The driven gear 202 then drives the top outer rotating cylinder 203 to rotate. The top outer rotating cylinder 203 drives the lifting ring 207 and the bottom outer rotating cylinder 208 to rotate together through the fixed slide rod 206, which in turn drives the mixing assembly 4 and the composite scraper assembly 5 to work.

[0040] The fermentation cylinder 1 is equipped with a discharge valve at the bottom, a bottom scraper 209 is fixedly installed on the outside of the bottom outer rotating cylinder 208, and protective telescopic covers 210 are fixedly installed at both ends of the lifting ring 207. The protective telescopic covers 210 are fixedly connected to the top outer rotating cylinder 203 and the bottom outer rotating cylinder 208 respectively.

[0041] When the bottom outer rotating cylinder 208 rotates, it can drive the bottom scraper 209 to rotate together, thereby scraping off the cow manure or waste attached to the bottom of the fermentation cylinder 1. It can also accelerate the flow of fertilizer during discharge, so that the fertilizer can be discharged from the discharge valve.

[0042] Reference Figure 1 , Figure 4 and Figure 5It also includes a receiving frame structure 3, which is located on the outside of the lifting ring 207. The receiving frame structure 3 includes a connector 301, a receiving connecting plate 302, an end-connecting fixed column 303, and an outer ring 304. The receiving frame structure 3 is used to connect the lifting ring 207 and the mixing assembly 4. Multiple connectors 301 are provided, and the connectors 301 are evenly distributed on the outside of the outer ring 304. The end-connecting fixed column 303 is fixedly provided at both ends of the connector 301. The receiving connecting plate 302 is fixedly provided between the connector 301 and the outer ring 304. The outer ring 304 is fixedly provided on the outside of the lifting ring 207.

[0043] Among them, multiple connectors 301, receiving plate 302, end-connecting column 303 and outer ring 304 are used to connect lifting ring 207 and multiple stirring components 4, so that the stirring components 4 can be lifted and lowered together when lifting ring 207 is lifted and lowered.

[0044] Reference Figure 1 and Figure 2 The top end cover 101 has an air inlet 103, an exhaust outlet 104 and a discharge outlet 105. A protective cover 102 is fixedly installed on the top end cover 101, and the servo motor 2 is fixedly installed inside the top end of the protective cover 102.

[0045] Cow dung, sawdust, straw, and other mixtures are fed into the fermentation tank 1 through the feed inlet 105. An oxygen generator is connected to the air inlet 103 to supply the oxygen required for fermentation into the fermentation tank 1.

[0046] Example 2:

[0047] Reference Figure 1 , Figure 6 and Figure 7 The interior of the fermentation tank 1 is symmetrically equipped with a composite scraper assembly 5. The composite scraper assembly 5 includes a connecting frame 501. The bottom end of the connecting frame 501 is slidably equipped with a diagonal bracing rib 502. An inner wall scraper 503 is fixedly installed on one side of the connecting frame 501. The inner wall scraper 503 is in contact with the inner wall of the fermentation tank 1. A connecting vertical plate 505 is fixedly installed at the other end of the diagonal bracing rib 502. A cleaning scraper 504 is installed on the side of the connecting vertical plate 505 near the inner wall of the fermentation tank 1. The cleaning scraper 504 is symmetrically slidably installed on the outside of the inner wall scraper 503. A centrifugal counterweight block 506 is fixedly installed on the other side of the connecting vertical plate 505. The connecting frame 501 is fixedly installed on the outside of the top outer rotating cylinder 203.

[0048] When the top outer rotating cylinder 203 rotates, it will drive the composite scraper assembly 5 to move together. The connecting frame 501 in the composite scraper assembly 5 will drive the inner wall scraper 503 and the cleaning scraper 504 to rotate. When the inner wall scraper 503 rotates, it will scrape off the cow dung attached to the inner wall of the fermentation cylinder 1, so that it can be fully fermented, improve the quality of waste, and reduce the difficulty of cleaning the servo motor 2 later. After working for a long time, a lot of cow dung will be attached to the surface of the inner wall scraper 503.

[0049] Specifically, refer to Figure 7 The cleaning scraper 504 has an end cap 5041 rotatably mounted at its top and bottom. The end cap 5041 is fixedly mounted on one side of the connecting vertical plate 505. The end cap 5041 has a return spring 5042 rotatably mounted symmetrically inside. The return spring 5042 is rotatably connected to the cleaning scraper 504. The top of the end cap 5041 is fixedly mounted with a top cover 5043.

[0050] By increasing the rotation speed of the top outer rotating drum 203, the cleaning scraper 504 can obtain centrifugal force, thereby sliding on the surface of the inner wall scraper 503 and cleaning the cow dung attached to its surface. When the cleaning scraper 504 cleans the surface of the inner wall scraper 503, the return spring 5042 will extend, thereby providing tension to the cleaning scraper 504, so that the cleaning scraper 504 can just fit against the surface of the inner wall scraper 503, achieving a better cleaning effect. If the centrifugal force on the cleaning scraper 504 decreases, the cleaning scraper 504 will return to its original position through the pull force of the elastic telescopic rod 5021, and the return spring 5042 will return to its original length, facilitating the next cleaning operation.

[0051] Furthermore, the top of the connecting frame 501 is provided with serrated teeth, and an elastic telescopic rod 5021 is fixedly provided on one side of the inclined brace rib 502. The elastic telescopic rod 5021 is fixedly provided on one side of the bottom end of the connecting frame 501.

[0052] The movement of the connecting frame 501 can break up some of the lumpy cow manure fed into the feed port 105, thereby improving the fermentation quality of the cow manure. When the inclined support 502 moves, the elastic telescopic rod 5021 will be compressed or released, which will give the inclined support 502 the power to reset, making it easier for the cleaning scraper 504 to return to its original position.

[0053] Working principle: Cow dung, sawdust, straw and other mixtures are fed into the fermentation tank 1 through the feed inlet 105. An oxygen generator is connected to the air inlet 103 to supply the oxygen required for fermentation into the fermentation tank 1.

[0054] When performing the turning and stirring work, the servo motor 2 is started. The servo motor 2 drives the drive gear 201 to rotate. The rotation of the drive gear 201 drives the driven gear 202 to rotate together. The driven gear 202 will drive the top outer rotating cylinder 203 to rotate. The top outer rotating cylinder 203 drives the lifting ring 207 and the bottom outer rotating cylinder 208 to rotate together through the fixed slide rod 206. The fixed column 204 and the lifting screw 205 are fixed. Therefore, when the lifting ring 207 rotates outside the lifting screw 205, it will rise or fall, thereby driving the stirring assembly 4 to stir and turn the cow dung mixture.

[0055] The bottom outer rotating cylinder 208 rotates while driving the bottom scraper 209 to move around, thereby preventing cow manure from sticking to the bottom of the fermentation cylinder 1 and ensuring that the cow manure at the bottom of the fermentation cylinder 1 is fully mixed.

[0056] Since the lifting ring 207 is connected to the outer ring 304 in the receiving frame structure 3, and is connected to the stirring assembly 4 through the end-connecting fixed column 303, the receiving connecting plate 302, and the connecting piece 301, the lifting ring 207 will synchronously drive the stirring assembly 4 to rise and fall during lifting, thereby performing the work of turning and stirring materials. When the stirring assembly 4 is lifted and lowered, the linkage gear 402 will mesh with the fixed tooth plate 407 and rotate. The rotation of the linkage gear 402 will drive the outer sleeve 401 to rotate, thereby achieving the desired effect. The linkage bevel gear 405 and the stirring plate 406 can move around the axis of the outer sleeve 401 to perform the mixing of materials. Since the fixed bevel gear 403 is stationary, the linkage bevel gear 405 will rotate on its own axis when it moves around the outside of the fixed bevel gear 403. This will drive the stirring plate 406 to rotate on its own axis while it moves around the fixed bevel gear 403, thus turning the material over and turning the waste material at the bottom upwards. This effectively dissipates excess heat, improves the fermentation quality, reduces manual intervention, and improves the turning efficiency.

[0057] While the top outer rotating drum 203 rotates, it drives the composite scraper assembly 5 to rotate as well. The connecting frame 501 in the composite scraper assembly 5 drives the inner wall scraper 503 and the cleaning scraper 504 to rotate. When the inner wall scraper 503 rotates, it scrapes off the cow dung attached to the inner wall of the fermentation drum 1, allowing it to ferment fully, improving the quality of the waste and reducing the difficulty of cleaning the servo motor 2 later. After working for a long time, a lot of cow dung will be attached to the surface of the inner wall scraper 503. By increasing the rotation speed of the top outer rotating drum 203, the cleaning scraper 504 can obtain centrifugal force, thereby sliding on the surface of the inner wall scraper 503 and cleaning the fertilizer or cow dung mixture attached to its surface. When the cleaning scraper 504 cleans the surface of the inner wall scraper 503, the return spring 5042 will extend, thereby providing tension to the cleaning scraper 504, so that the cleaning scraper 504 can just fit against the surface of the inner wall scraper 503, achieving a better cleaning effect.

[0058] The centrifugal counterweight 506 is designed to provide the cleaning scraper 504 with a stronger centrifugal force, allowing the cleaning scraper 504 to quickly adhere to and clean the surface of the inner wall scraper 503. The movement of the connecting frame 501 can break up some of the lumpy cow manure fed into the feed port 105, thereby improving the fermentation quality of the cow manure.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
