[0001] The invention relates to the technical field of producing biological organic fertilizer from cow dung, in particular to a method for producing biological organic fertilizer from cow dung. Background Art

[0002] As a new type of fertilizer, bio-organic fertilizer is rich in organic matter, trace elements and bioactive substances, which can significantly improve soil structure, increase soil fertility, reduce the use of chemical fertilizers and pesticides, and thus promote green and sustainable agricultural development. The production of bio-organic fertilizer from organic waste such as cow dung not only solves the problem of cow dung treatment, but also realizes the recycling of resources, which has important economic, social and ecological benefits.

[0003] At present, the existing methods of producing biological organic fertilizer using cow dung are mostly to squeeze the cow dung first to squeeze out the water, then dry it, then pour the fermentation agent into the cow dung and mix it, and finally ferment it in a closed manner to obtain biological organic fertilizer. However, in the process of drying the cow dung, the water generated is directly discharged and has no effect of reuse. Moreover, after squeezing and drying the cow dung, the cow dung is still in a large volume, and it cannot be guaranteed that the cow dung can be fully mixed with the fermentation agent, which affects the fermentation effect.

[0004] Therefore, a method for producing biological organic fertilizer using cow dung is urgently needed to solve the problems of the prior art. Summary of the invention

Under the action of the thrust, the other end of the folding rod generates a downward thrust on the telescopic block, so that the blade is exposed on the surface of the lifting ring. Since the lower surface of the blade is parallel to the position of the through holes opened around the lower surface of the extrusion cylinder, when the extrusion die squeezes the cow dung inside the extrusion cylinder, under the action of the extrusion force, part of the cow dung can be exposed through the through holes, and the blade is used to cut the cow dung into blocks, which helps the cow dung to maintain a certain shape and volume during the fermentation process, making the fermentation process more uniform, and also helps to evenly distribute the fermentation agent inside and on the surface of the cow dung in the subsequent process, thereby improving the fermentation efficiency.

[0017] 4. The method of producing biological organic fertilizer by using cow dung is as follows: the block cow dung on the surface of the slide is dried and transferred to the surface of the rotating plate; under the gravity of the block cow dung, the rotating plate is rotated on the upper surface of the collecting box; at the same time, the connecting rod drives the adjusting plate to slide downward; since one side of the adjusting plate surface is connected with the surface position of the guide trough correspondingly, the fermentation agent stored in the guide trough can be introduced into the surface of the rotating plate, the fermentation agent is applied to the surface of the block cow dung, and finally falls into the collecting box, and is fermented in a closed manner for a period of time, and finally the biological organic fertilizer is generated, which can effectively avoid the problem of excessive use of the fermentation agent and waste.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] See also Figure 1 - Fig. 9 As shown, the present embodiment aims to provide a method for producing biological organic fertilizer using cow dung, comprising the following steps: S1, cow dung extrusion treatment: the extrusion die 203 reciprocates to extrude the cow dung placed inside the extrusion cylinder 204, and the water generated by the reciprocating extrusion of the cow dung is transmitted to the water collecting cylinder 207. Meanwhile, during the extrusion process, the through holes 211 provided around the lower surface of the extrusion cylinder 204 can be used to orderly squeeze out the excess cow dung, thereby improving the reuse of water; S2, drying and cutting of cow dung: the electric steam generator 208 heats the water in the water collecting cylinder 207 to generate steam, and the air guide pipe 209 and the heat dissipation pipe 210 are used to dry the cow dung. At the same time, when the extrusion die 203 reciprocates, the lifting ring 301 and the extrusion die 203 reciprocate synchronously. Under the linkage of the folding rod 306 and the telescopic block 307, the blade 308 extends from the lower surface of the lifting ring 301 to cut the cow dung extruded from the surface of the through hole 211, which helps the cow dung to maintain a certain shape and volume during the fermentation process, making the fermentation process more uniform, and also helps the fermentation agent to be evenly distributed inside and on the surface of the cow dung in the subsequent process, thereby improving the fermentation efficiency; S3, cow dung smearing fermentation agent and fermentation treatment: the cow dung cut into blocks falls onto the surface of the rotating plate 402, and the rotating plate 402 is rotated under the pressure of the cow dung's own weight, and the adjusting plate 404 is pulled down under the connection of the connecting rod 403. Since one side of the surface of the adjusting plate 404 is correspondingly connected to the guide trough 104, the fermentation agent inside the guide trough 104 can be dropped onto the surface of the cow dung, and fermented in a closed manner inside the collecting box 401 to generate biological organic fertilizer, which can effectively avoid the problem of excessive use of the fermentation agent and waste.

[0022] Among them, the production equipment used in this method includes a sealing mechanism 100, an extrusion mechanism 200, a cutting and transmission mechanism 300 and a collecting mechanism 400. The extrusion mechanism 200 is movably installed on the inner top of the sealing mechanism 100, the cutting and transmission mechanism 300 is movably installed on the lower surface of the extrusion mechanism 200, and the collecting mechanism 400 is arranged around the lower surface of the cutting and transmission mechanism 300.

[0023] according to Figure 1 and Figure 4 As shown, the specific structure of the sealing mechanism 100 is disclosed. The sealing mechanism 100 includes a sealing tank 101, a cover plate 102 is installed on the upper surface of the sealing tank 101, hanging rings 103 are installed on both sides of the upper surface of the cover plate 102, the cover plate 102 is separated from the upper surface of the sealing tank 101 by the hanging rings 103, a control panel 106 is arranged at the center of the surface of the sealing tank 101, the sealing tank 101 is arranged on the surface of the sealing mechanism 100, a material guide groove 104 is installed at the center of the outer surface of the sealing tank 101, and the material guide groove 104 is connected to the feed port 105 on both sides of the surface; Furthermore, by using the hanging ring 103 to separate the cover plate 102 from the upper surface of the sealed tank 101, the extrusion cylinder 204 clamped inside the sealed tank 101 can be displayed, and then the cow dung can be placed inside the extrusion cylinder 204. After completion, the cover plate 102 is sealed and clamped on the upper surface of the sealed tank 101, the hydraulic pump 201 is started, and the extrusion die 203 is pressed down on the upper surface of the extrusion cylinder 204 to extrude the cow dung. The improvement lies in that the cow dung is sealed and squeezed. After the squeezing is completed, the cow dung can be directly cut and finally sealed and transferred to the inside of the collection mechanism 400, and the cow dung is fermented in a closed manner to generate biological organic fertilizer.

[0024] according to Figure 2 and Figure 6As shown, the specific structure of the extrusion mechanism 200 is disclosed. An extrusion die 203 is installed on the upper surface of the extrusion mechanism 200. A water collecting cylinder 207 is connected to the lower surface of the extrusion cylinder 204. An electric steam generator 208 is installed on the lower surface of the water collecting cylinder 207. An air guide tube 209 is connected to the upper surface of the water collecting cylinder 207. The extrusion die 203 reciprocates and extrude the cow dung inside the extrusion cylinder 204. Through holes 211 are provided around the lower surface of the extrusion cylinder 204. An extrusion cylinder 204 is installed inside the extrusion mechanism 200. The cow dung is placed inside the extrusion cylinder 204. A hydraulic pump 201 is installed at the center of the upper surface of the cover plate 102. A fixed shaft 202 is fixedly connected to the lower surface of the hydraulic pump 201. The hydraulic pump 201 is connected to the extrusion die 203 via the fixed shaft 202. Slots 205 are provided on both sides of the upper surface of the extrusion cylinder 204. A contact block 206 is installed on one side of the surface of the slot 205. Furthermore, the cow dung inside the extrusion cylinder 204 is reciprocatedly extruded by the extrusion die 203, and the residual water in the cow dung is transferred to the water collecting cylinder 207 through the extrusion cylinder 204. The electric steam generator 208 is started to heat the water in the water collecting cylinder 207 to generate steam, and the steam generated by the water heating in the water collecting cylinder 207 is transferred to the position of the air guide pipe 209. The improvement lies in that the cow dung is reciprocatedly extruded by the extrusion die 203 to squeeze out the residual water inside the cow dung and store it in the water collecting cylinder 207, and the water is heated by the electric steam generator 208 to generate steam to dry the surface of the cow dung, thereby effectively improving the efficiency and effect of the cow dung treatment.

[0025] according to Figure 3 , Figure 5 and Figure 7 As shown, the specific structure of the cutting and conveying mechanism 300 is disclosed. A lifting ring 301 is installed on the surface of the cutting and conveying mechanism 300. Guide rails 303 are installed on both sides of the inner wall of the lifting ring 301. One side of the guide rail 303 is fixedly installed on the left and right sides of the surface of the extrusion cylinder 204. A slider 304 is connected to one side of the lifting ring 301. A telescopic spring 305 is connected to the upper surface of the slider 304. A folding rod 306 is movably installed on the upper surface of the telescopic spring 305. A telescopic block 307 is installed on the lower surface of the folding rod 306. A blade 308 is installed on the lower surface of the telescopic block 307. A slideway 302 is connected to one side of the surface of the through hole 211, so that the cow dung cut into blocks slides on the surface of the slideway 302. Furthermore, the lifting and lowering movement of the extrusion die 203 drives the lifting ring 301 to rise and fall synchronously, the guide rail 303 and the card slot 205 are lifted and lowered, and the slider 304 and the contact block 206 are squeezed and extruded at the same time, driving the slider 304 to slide upward, so that one end of the folding rod 306 moves downward, and the telescopic block 307 slides downward on the surface of the lifting ring 301, so that the blade 308 extends from the outer surface of the lifting ring 301 and contacts the surface position of the through hole 211. Since the through hole 211 can guide the excess cow dung from the inside of the extrusion cylinder 204 after reciprocating extrusion, the cow dung can be cut into blocks by the reciprocating lifting and lowering movement of the blade 308, and slides from the surface of the slideway 302 to the surface of the rotating plate 402; The improvement lies in: since the existing production of biological organic fertilizer from cow dung is mostly done by sealing the cow dung as a whole and placing it in a closed container, and mixing the fermentation agent with the cow dung, there is still a small amount of cow dung that cannot be completely mixed with the fermentation agent, affecting the utilization effect of the cow dung. Cutting the cow dung can effectively increase the contact between the cow dung and the fermentation agent, thereby increasing the fertilizer value of the cow dung and promoting the recycling and sustainable development of resources.

[0026] according to Figure 8 As shown, the specific structure of the collecting mechanism 400 is disclosed. A collecting box 401 is installed on the surface of the collecting mechanism 400. A rotating plate 402 is rotatably connected to the upper surface of the collecting box 401. When the dried cow dung falls to one side of the surface of the rotating plate 402, the rotating plate 402 is rotated under the action of pressure. At the same time, connecting rods 403 are connected to both sides of the upper surface of the rotating plate 402. One side of the surface of the connecting rod 403 is connected to an adjusting plate 404. Under the connecting action of the connecting rod 403, the adjusting plate 404 is pulled down. Furthermore, the cow dung cut into blocks is transferred to the surface of the rotating plate 402. Under the action of the weight of the cow dung itself, the rotating plate 402 can be tilted, so that the connecting rod 403 drives the adjusting plate 404 to adjust downward. Since the adjusting plate 404 and the surface of the guide trough 104 are parallel and corresponding, the guide trough 104 and the surface of the rotating plate 402 are connected to each other, and the fermentation agent in the guide trough 104 falls to the surface of the rotating plate 402, and the fermentation agent is applied to the surface of the cow dung. Finally, the cow dung falls into the collecting box 401, and the cow dung is subjected to a closed fermentation treatment. The improvement lies in that the fermentation agent is quantified by connecting rod 403 and spread on the surface of cow dung. Finally, the cow dung is centrally stored in the collecting box 401 and the cow dung is fermented in a closed manner to avoid the problem of waste of the fermentation agent and to evenly spread the fermentation agent on the surface of the cow dung.

[0027] In summary, the working principle of the present invention is as follows: the cover plate 102 can be opened by the hanging ring 103 to expose the extrusion cylinder 204, and then the cow dung is poured into the extrusion cylinder 204. The cover plate 102 is sealed on the upper surface of the sealing tank 101, and the hydraulic pump 201 is started. Finally, the extrusion die 203 moves up and down on the lower surface of the fixed shaft 202, and is engaged with the lifting and lowering inside the extrusion cylinder 204 to extrude the cow dung. The extrusion die 203 moves downward, driving the lifting ring 301 to descend synchronously, and the guide rail 303 and the card slot 205 are correspondingly engaged, so that the contact block 206 effectively generates an upward thrust on the slider 304, and the telescopic spring 305 can squeeze the upper end of the folding rod 306. Under the action of, the other end of the folding rod 306 generates a downward thrust on the telescopic block 307, thereby allowing the blade 308 to be exposed on the surface of the lifting ring 301. Since the lower surface of the blade 308 is parallel to the through holes 211 opened around the lower surface of the extrusion cylinder 204, when the extrusion die 203 squeezes the cow dung inside the extrusion cylinder 204, under the action of the extrusion force, part of the cow dung can be exposed through the through holes 211, and the blade 308 is used to cut the cow dung into blocks, which helps the cow dung to maintain a certain shape and volume during the fermentation process, making the fermentation process more uniform, and also helps the fermentation agent to be evenly distributed inside and on the surface of the cow dung in the future, thereby improving the fermentation efficiency; The cow dung cut into blocks is transferred to the surface of the slide 302 at the position of the through hole 211. The extrusion process of the cow dung inside the extrusion cylinder 204 will generate moisture, which is introduced into the water collecting cylinder 207 through the extrusion cylinder 204. The electric steam generator 208 is set to heat the moisture in the water collecting cylinder 207 to generate water vapor, and the water vapor is transferred to the position of the heat dissipation pipe 210 from the set air guide pipe 209. Since the surface of the heat dissipation pipe 210 is correspondingly connected to the surface of the slide 302, the generated water vapor can dry the block cow dung transferred on the surface of the slide 302, effectively improving the subsequent process of fermenting cow dung to generate biological organic fertilizer. In order to improve the working efficiency, the block cow dung on the surface of the slide 302 is dried and transferred to the surface of the rotating plate 402. Under the action of the gravity of the block cow dung, the rotating plate 402 rotates on the upper surface of the collecting box 401, and the connecting rod 403 drives the adjusting plate 404 to slide downward. Since one side of the adjusting plate 404 is connected with the surface position of the guide trough 104 correspondingly, the fermentation agent stored in the guide trough 104 can be introduced into the surface of the rotating plate 402, and the fermentation agent is applied to the surface of the block cow dung, and finally falls into the collecting box 401, and is fermented for a period of time, and finally generates biological organic fertilizer, which can effectively avoid the problem of excessive use of the fermentation agent and waste.
