Description

Technical Field

[0001] This invention relates to the field of bio-organic fertilizer production technology, specifically a mixing device for the production and processing of pig manure organic fertilizer. Background Technology

[0002] Currently, the production of pig manure organic fertilizer mainly adopts trough composting or reactor fermentation technology. By adding auxiliary materials to adjust the carbon-nitrogen ratio, and using turning or forced ventilation to supply oxygen, the composting is completed in 15 to 30 days at high temperature. By 2025, the industry is shifting to innovative processes such as intelligent conical drum stirring and low-temperature plasma deodorization. Direct discharge of pig manure leads to eutrophication of water bodies, greenhouse gas and pathogen pollution, and requires harmless treatment.

[0003] Current pig manure mixing devices mainly have the following problems:

[0004] Traditional mixing devices typically use a fixed speed or a single mixing method, which is difficult to cope with the viscosity fluctuations caused by changes in moisture content during the production of pig manure organic fertilizer, and is prone to problems such as uneven mixing or excessive mixing resistance.

[0005] To address the above issues, a mixing device for the production and processing of pig manure organic fertilizer is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a mixing device for the production and processing of pig manure organic fertilizer. By using this device, the problems of traditional mixing devices, which usually use a fixed speed or a single mixing method, are difficult to cope with the viscosity fluctuations caused by changes in moisture content during the production of pig manure organic fertilizer, and are prone to uneven mixing or excessive mixing resistance are solved.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A mixing device for producing and processing pig manure organic fertilizer is provided, comprising a mixing base and a drum assembly. The drum assembly is rotatably connected to the mixing base, and a drive assembly is connected to the mixing base. The lower end of the drive assembly is connected to the drum assembly via a synchronous belt drive. A plurality of spiral track assemblies are rotatably connected to the inner wall of the drum assembly. The plurality of spiral track assemblies are arranged in a ring around the axis of the drum assembly. One end of each spiral track assembly is rotatably connected to the drum assembly and fixedly connected to one end of each of a plurality of angle rod assemblies. The other end of each angle rod assembly is slidably connected to a polygonal connecting ring assembly. The polygonal connecting ring assembly is slidably connected to the drum assembly and is sleeved on the outside of the drum assembly. Two push-pull assemblies are arranged on the outside of the drum assembly. The two push-pull assemblies are symmetrically arranged on any plane containing the axis of the drum assembly. The push-pull assemblies are located below the polygonal connecting ring assembly. The upper end of the polygonal connecting ring assembly is fixedly connected to the push-pull assembly, and the lower end of the push-pull assembly is fixedly connected to the outside of the drum assembly.

[0009] Furthermore, the drive assembly includes a motor, which is fixedly connected to the stirring base. The output end of the motor is fixedly connected to a synchronous pulley, and the synchronous pulley is connected to the lower end of the drum assembly via a synchronous belt drive.

[0010] Furthermore, the roller assembly includes a roller body, the lower end of which is rotatably connected to the upper end of the stirring base, and a cap is connected to the upper end of the roller body.

[0011] Furthermore, the lower end of the roller body is fixedly connected to the upper end of the rotating shaft, and the lower end of the rotating shaft is fixedly connected to the second synchronous pulley. The roller body, the cover, the rotating shaft, and the second synchronous pulley are concentrically arranged, and the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive.

[0012] Furthermore, each of the spiral track assemblies includes a connecting shaft, and the connecting shafts are rotatably connected to the cylinder wall of the drum body. The connecting shafts are arranged in a ring around the axis of the drum body, with one end of the connecting shaft located inside the drum body and the other end located outside the drum body.

[0013] Furthermore, the inner side of the roller body is provided with a plurality of spiral guide plates, which are arranged in a ring around the axis of the roller body. One end of each spiral guide plate is fixedly connected to one end of each connecting shaft located inside the roller body, and the other end of each connecting shaft is fixedly connected to one end of each angle rod assembly.

[0014] Furthermore, each of the aforementioned angle rod assemblies includes a swing connecting rod, and one end of each of the aforementioned swing connecting rods is fixedly connected to the other end of each of the aforementioned connecting shafts.

[0015] Furthermore, the other ends of several of the swing connecting rods are respectively fixedly connected to one end of several sliding rods, and the other ends of several sliding rods are slidably connected to the polygonal connecting ring assembly.

[0016] Furthermore, the polygonal connecting ring assembly includes a polygonal connecting ring body and a plurality of guide rods. The polygonal connecting ring body is sleeved on the outside of the roller body. The plurality of guide rods are arranged in a ring with the roller body axis as the center. The axes of the plurality of guide rods are parallel to the roller body axis. The lower ends of the plurality of guide rods are fixedly connected to the outside of the roller body. The polygonal connecting ring body has a plurality of sliding grooves. The other end of the sliding rod is slidably connected in the sliding groove.

[0017] Furthermore, both push-pull assemblies include cylinders, which are symmetrically arranged about the center of the roller body axis. The cylinders are located on the outside of the roller body, with the lower end of the cylinder fixedly connected to the roller body and the upper end of the cylinder fixedly connected to one end of a connecting rod. The other end of the connecting rod is fixedly connected to the polygonal connecting ring body, and the axis of the cylinder is parallel to the axis of the roller body.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The spiral track assembly, the angled rod assembly, and the multi-sided connecting ring assembly form a linkage system. The reciprocating rotation of the spiral track assembly is achieved by the cylinder, which makes the mixing method more diverse. It can fully cope with the problem of uneven mixing or excessive mixing resistance caused by the viscosity fluctuation due to the change in water content during the production of pig manure organic fertilizer.

[0020] 2. Through the linkage design of the spiral track assembly and the push-pull assembly, it can simultaneously process high-viscosity and low-viscosity pig manure. At low speeds, it relies on centrifugal force to mix low-viscosity materials, while high-viscosity materials are mechanically forced to be lifted and stirred, automatically adapting to the stirring requirements of different viscosities. For low-viscosity materials, it relies on centrifugal force to swirl, while for high-viscosity materials, it uses a swing mechanism to assist in stirring.

[0021] 3. When producing pig manure organic fertilizer using pig manure as the main raw material, the pig manure is first stirred and added into the drum assembly. The stirring mode can be dynamically adjusted according to the state of the mixture.

[0022] 4. The spiral track assembly, the angled rod assembly, and the multi-sided connecting ring assembly form a linkage system. The angle of the spiral track is adjusted by the cylinder, which solves the problem of dead zones in the mixing of high-viscosity materials in traditional devices and eliminates the dead zones.

[0023] 5. By stopping the rotation of the drive component, the pig manure moves upward along the spiral track component under the action of inertia. Then, it falls back to the bottom of the drum component under the action of gravity for mixing. This effectively reduces the damage to the active substances mixed in the pig manure caused by mechanical stirring, allowing the active substances to play a better role in the production of pig manure organic fertilizer and avoiding the waste of active substances due to damage.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Reference Figure 1 As shown, a mixing device for producing and processing pig manure organic fertilizer includes a mixing base 1 and a drum assembly 2. The drum assembly 2 is rotatably connected to the mixing base 1. A drive assembly 3 is connected to the mixing base 1. The lower end of the drive assembly 3 is connected to the drum assembly 2 via a synchronous belt drive. (Refer to...) Figure 2 As shown, several spiral track assemblies 4 are rotatably connected to the inner wall of the roller assembly 2. These spiral track assemblies 4 are arranged in a ring around the axis of the roller assembly 2. One end of each spiral track assembly 4 is rotatably connected to the roller assembly 2 and fixedly connected to one end of each of several angle rod assemblies 5. (Refer to...) Figure 3 As shown, the other ends of several angled rod assemblies 5 are slidably connected to the polygonal connecting ring assembly 6, which is slidably connected to the roller assembly 2. The polygonal connecting ring assembly 6 is sleeved on the outside of the roller assembly 2. (Refer to...) Figure 4 As shown, two push-pull components 7 are provided on the outer side of the roller assembly 2. The two push-pull components 7 are symmetrically arranged on any plane where the axis of the roller assembly 2 is located. The push-pull components 7 are located below the polygonal connecting ring assembly 6. The polygonal connecting ring assembly 6 is fixedly connected to the upper end of the push-pull components 7, and the lower end of the push-pull components 7 is fixedly connected to the outer side of the roller assembly 2.

[0043] When producing pig manure organic fertilizer, an appropriate amount of pig manure is put into the drum assembly 2, and then the drive assembly 3 is started, so that the drive assembly 3 rotates on the mixing base 1. At the same time, through the transmission action of the synchronous belt, the drum assembly 2 is driven to rotate together when the drive assembly 3 rotates. Through the rotation of the drum assembly 2, the pig manure in the drum assembly 2 is initially mixed with other organic matter. When the drum assembly 2 rotates, it also drives the spiral track assembly 4, the angle rod assembly 5, the polygonal connecting ring assembly 6 and the push-pull assembly 7 to rotate at the same speed. In the initial state, one end of the spiral track assembly 4 is in contact with the bottom of the drum assembly 2.

[0044] For pig manure with low viscosity, the roller assembly 2 initially rotates at a low speed, and the low-viscosity pig manure mainly concentrates at the bottom of the roller assembly 2. Due to the friction between the low-viscosity pig manure and the bottom, the pig manure rotates at the same speed as the roller assembly 2. As the speed of the drive assembly 3 increases, the speed of the roller assembly 2 also increases. The friction between the pig manure and the bottom of the roller assembly 2 is insufficient to provide the centripetal force required for it to rotate at the same speed as the roller assembly 2. At this point, the pig manure flows towards the inner wall of the roller assembly 2. Under the supporting force of the inner wall of the roller assembly 2, the pig manure flows towards the inner wall of the roller assembly 2. Continuing to perform circular motion, when the drive component 3 suddenly stops rotating, the roller component 2 also stops rotating. At this time, the pig manure flows to the spiral track component 4 under the action of inertia, flows upward along the spiral track component 4, and then flows out from the top of the spiral track component 4. During this process, by stopping the rotation of the drive component 3, the pig manure moves upward along the spiral track component 4 under the action of inertia, and then falls back to the bottom of the roller component 2 under the action of gravity. Mixing and stirring can effectively avoid damage to the active substances mixed in the pig manure by mechanical stirring.

[0045] For highly viscous pig manure, when the roller assembly 2 rotates at low or high speed, due to its high viscosity, the pig manure mainly concentrates at the bottom of the roller assembly 2, with a small amount existing on the inner edge of the roller assembly 2. When the drive assembly 3 suddenly stops rotating, the small amount of pig manure on the inner edge is pushed onto the spiral track assembly 4 by inertia, some of which flows out from the top of the spiral track assembly 4 and falls back to the bottom of the roller assembly 2 under gravity. Most of the manure, due to its high viscosity, adheres to the spiral track assembly 4 or exists at the bottom of the roller assembly 2. At this time, the push-pull assembly 7 can be activated to... The upper end of the push-pull assembly 7 pulls the polygonal connecting ring assembly 6 to slide downward on the outside of the roller assembly 2. When the polygonal connecting ring assembly 6 slides downward, it drives the angled rod assembly 5 to rotate clockwise downward. The rotation of the angled rod assembly 5 drives the spiral track assembly 4 to rotate clockwise as well, causing the end of the spiral track assembly 4 that abuts against the bottom of the roller assembly 2 to lift up, thereby picking up the pig manure at the bottom of the roller assembly 2. Then, the components move in the opposite direction, that is, the spiral track assembly 4 rotates counterclockwise, causing the picked-up pig manure to detach from the spiral track assembly 4 and fall to the bottom of the roller assembly 2, thereby achieving the effect of mixing and stirring.

[0046] Reference Figure 5 As shown, the drive assembly 3 includes a motor 31, which is fixedly connected to the stirring base 1. The output end of the motor 31 is fixedly connected to the synchronous pulley 32, and the synchronous pulley 32 is connected to the lower end of the drum assembly 2 via a synchronous belt drive.

[0047] When mixing pig manure with other organic matter, the output end of the motor 31 is turned by starting the motor 31. When the output end of the motor 31 is turned, it drives the synchronous wheel 32, which is fixedly connected to it, to rotate together.

[0048] The drum assembly 2 includes a drum body 21, the lower end of which is rotatably connected to the upper end of the stirring base 1, and a cover 22 is connected to the upper end of the drum body 21.

[0049] Open the cover 22 and add the pig manure and other organic matter into the drum body 21.

[0050] Reference Figure 10 As shown, the lower end of the roller body 21 is fixedly connected to the upper end of the rotating shaft 23, and the lower end of the rotating shaft 23 is fixedly connected to the second synchronous pulley 24. The roller body 21, the cover 22, the rotating shaft 23 and the second synchronous pulley 24 are arranged concentrically. The first synchronous pulley 32 and the second synchronous pulley 24 are connected by a synchronous belt drive.

[0051] When the first synchronous pulley 32 rotates, it causes the second synchronous pulley 24 to rotate together through the transmission action of the synchronous belt, which in turn drives the rotating shaft 23, which is fixedly connected to the second synchronous pulley 24, to rotate. Since the rotating shaft 23 is fixedly connected to the lower end of the drum body 21, the rotating shaft 23 drives the drum body 21 to rotate together when it rotates.

[0052] Reference Figure 6 As shown, each of the several spiral track assemblies 4 includes a connecting shaft 41, and the several connecting shafts 41 are rotatably connected to the cylinder wall of the roller body 21. The several connecting shafts 41 are arranged in a ring with the axis of the roller body 21 as the center. One end of the connecting shaft 41 is located inside the roller body 21, and the other end of the connecting shaft 41 is located outside the roller body 21.

[0053] When the drum body 21 rotates, it drives the connecting shaft 41 to rotate together.

[0054] Reference Figure 9 As shown, a plurality of spiral guide plates 42 are provided on the inner side of the roller body 21. The plurality of spiral guide plates 42 are arranged in a ring around the axis of the roller body 21. One end of the plurality of spiral guide plates 42 is fixedly connected to one end of a plurality of connecting shafts 41 located on the inner side of the roller body 21. The other end of the plurality of connecting shafts 41 is fixedly connected to one end of a plurality of angle rod assemblies 5.

[0055] Since the spiral guide plate 42 is fixedly connected to one end of the connecting shaft 41 located inside the drum body 21, the connecting shaft 41 drives the spiral guide plate 42 to rotate synchronously when the drum body 21 rotates. Since the other end of the connecting shaft 41 is fixedly connected to one end of several angle rod assemblies 5, the connecting shaft 41 drives the angle rod assemblies 5 to rotate together when the drum body 21 rotates.

[0056] Reference Figure 7 As shown, each of the several angle rod assemblies 5 includes a swing connecting rod 51, and one end of each swing connecting rod 51 is fixedly connected to the other end of a number of connecting shafts 41.

[0057] Since one end of each of the several swing connecting rods 51 is fixedly connected to the other end of each of the several connecting shafts 41, when the connecting shafts 41 rotate synchronously with the drum body 21, they drive the swing connecting rods 51 to rotate together. At the same time, when the swing connecting rods 51 rotate around the position where they are fixedly connected to the connecting shafts 41, they drive the connecting shafts 41 to rotate on the drum body 21, and at the same time drive the spiral guide plate 42 to rotate together, that is, the spiral guide plate 42 rotates inside the drum body 21.

[0058] Reference Figure 8 As shown, the other ends of several swing connecting rods 51 are fixedly connected to one end of several sliding rods 52, and the other ends of several sliding rods 52 are slidably connected to the polygonal connecting ring assembly 6.

[0059] When several swing connecting rods 51 rotate synchronously with the roller body 21, they drive the slide rods 52, which are fixedly connected to them, to rotate together. The upper end of the polygonal connecting ring assembly 6 is fixedly connected to the push-pull assembly 7, and the lower end of the push-pull assembly 7 is fixedly connected to the outside of the roller assembly 2. Therefore, when the roller body 21 rotates, it drives the polygonal connecting ring assembly 6 and the push-pull assembly 7 to rotate synchronously. Because the polygonal connecting ring assembly 6 is slidably connected to the roller assembly 2, when the polygonal connecting ring assembly 6 slides up and down, it drives the slide rod 52 to move up and down. At the same time, the slide rod 52 slides on the polygonal connecting ring assembly 6. Through the movement of the slide rod 52, the swing connecting rod 51 rotates around the position where it is fixedly connected to the connecting shaft 41.

[0060] The polygonal connecting ring assembly 6 includes a polygonal connecting ring body 61 and a plurality of guide rods 62. The polygonal connecting ring body 61 is sleeved on the outside of the roller body 21. The plurality of guide rods 62 are arranged in a ring with the axis of the roller body 21 as the center. The axis of the plurality of guide rods 62 is parallel to the axis of the roller body 21. The lower ends of the plurality of guide rods 62 are fixedly connected to the outside of the roller body 21. The polygonal connecting ring body 61 is provided with a plurality of sliding grooves 63. The other end of the sliding rod 52 is slidably connected in the sliding groove 63.

[0061] Due to the action of the push-pull assembly 7, the polygonal connecting ring body 61 slides up and down on the guide rod 62. When the polygonal connecting ring body 61 slides up and down, it drives the slide rod 52 to move up and down. At the same time, the slide rod 52 slides in the slide groove 63. The movement of the slide rod 52 drives the swing connecting rod 51 to rotate around the position where it is fixedly connected to the connecting shaft 41.

[0062] Both push-pull assemblies 7 include cylinders 71. The two cylinders 71 are symmetrically arranged about the axis of the roller body 21. The cylinders 71 are located on the outside of the roller body 21. The lower end of the cylinder 71 is fixedly connected to the roller body 21, and the upper end of the cylinder 71 is fixedly connected to one end of the connecting rod 72. The other end of the connecting rod 72 is fixedly connected to the polygonal connecting ring body 61. The axis of the cylinder 71 is parallel to the axis of the roller body 21.

[0063] When the pig manure is highly viscous, when the motor 31 stops rotating, the output end of the cylinder 71 contracts, which in turn drives the connecting rod 72 to move downward, causing the polygonal connecting ring body 61 to slide downward, and the slide rod 52 to move downward. At the same time, the slide rod 52 slides to the left in the slide groove 63. The movement of the slide rod 52 drives the swing connecting rod 51 to rotate around its fixed connection position with the connecting shaft 41, which in turn causes the connecting shaft 41 to rotate clockwise. The clockwise rotation of the connecting shaft 41 drives the spiral guide plate 42 to rotate clockwise as well, thereby picking up the highly viscous pig manure from the bottom of the drum body 21. Then the output end of the cylinder 71 extends, and the spiral guide plate 42 rotates counterclockwise, scattering the pig manure on the spiral guide plate 42 to achieve the effect of mixing and stirring.
