Description

Technical Field

[0001] This application relates to the technical field of fertilizer production equipment, and in particular to a rice straw recycling compost fermentation device. Background Art

[0002] Rice straw contains a large amount of organic matter such as nitrogen, phosphorus, potassium, and calcium, and is a renewable biological resource with multiple uses. The composting process of straw is an effective measure to utilize straw, and returning straw to the field through the composting process can maintain the fertility of the land.

[0003] In the traditional composting process, the straw needs to be crushed first, and then the straw and some additives are stacked. Subsequently, the stack can ferment by itself. During the fermentation process, the stack needs to be turned over. On the one hand, it reduces the situation of excessive temperature inside the stack, and on the other hand, it enables the organic matter to effectively contact oxygen. The traditional composting process not only requires a large amount of space, but also the methods of manual stacking and turning over are inefficient and consume manpower and material resources. Therefore, a composting tank appears in the related technology, which mainly includes a silo and a stirring device. The silo is cylindrical, and the stirring device is arranged inside the silo for turning over the organic matter, replacing manual turning over and reducing the labor burden of the staff. For example, a patent document with the publication number CN118702513B discloses an organic fertilizer high-temperature composting fermentation system and method, which automatically turns over the fertilizer raw materials through the stirring plates arranged in the fermentation tank.

[0004] During the actual composting process, the overall diameter of the fermentation tank is at least between three and five meters; the length of the stirring plate is also at least about two meters. During the stirring process of the stirring plate on the material, on the one hand, it is difficult to effectively stir the material, and on the other hand, due to the accumulation of the material, it is more laborious for the stirring plate to stir it, and the stirring plate is prone to deformation. Therefore, the turning efficiency of the composting device in the related technology needs to be further improved during use. Summary of the Invention

[0005] In order to improve the turning efficiency of the fertilizer, this application provides a rice straw recycling compost fermentation device.

[0006] The rice straw recycling compost fermentation device provided by this application adopts the following technical solutions: A rice straw recycling compost fermentation device, comprising a frame and a fermentation barrel installed on the frame. One end of the fermentation barrel is provided with a material inlet; a sealing door for controlling its own opening and closing is arranged in the material inlet. The fermentation barrel is horizontally arranged and rotatably connected to the frame. A stirring assembly is arranged inside the fermentation barrel. The stirring assembly includes a plurality of fixed plates arranged at intervals along the direction of a spiral line coaxial with the fermentation barrel, and movable plates arranged corresponding to the gaps between two adjacent fixed plates. The movable plates and the fixed plates form a spiral plate-like structure. The movable plates are rotatably connected to the fermentation barrel, and the rotation axis of the movable plates is perpendicular to the rotation axis of the fermentation barrel.

[0007] By adopting the above technical solution, the fermentation barrel is used to hold fertilizer raw materials. During the process of rotating the fermentation barrel, the fertilizer raw materials in the fermentation barrel can automatically roll and turn under the action of their own gravity, realizing the turning of the fertilizer raw materials. At the same time, rotate the movable plates. When the inclination direction of the movable plates is opposite to that of the fixed plates, the following phenomenon will occur: during the rotation of the fermentation barrel, the fixed plates drive the fertilizer raw materials to move towards one end of the fermentation barrel, while the movable plates drive the fertilizer raw materials to move towards the other end, realizing the reciprocating turning of the fertilizer raw materials and improving the turning effect of the fertilizer raw materials. At the same time, when the fertilizer fermentation is completed, by rotating the movable plates to make their inclination directions the same as those of the fixed plates, at this time, the fixed plates and the movable plates together form a whole spiral plate. During the rotation of the fermentation barrel, it can drive the fermented fertilizer to move towards one side end of the fermentation barrel, facilitating the discharging of the fertilizer.

[0008] Optionally, the fixed plates are divided into multiple groups in the circumferential direction of the fermentation barrel, and the projections of the multiple fixed plates in the same group on a plane perpendicular to the rotation axis of the fermentation barrel coincide.

[0009] By adopting the above technical solution, the projections of the fixed plates on a plane perpendicular to the rotation axis direction of the fermentation barrel coincide, that is, the distance between two adjacent fixed plates in the same group in the direction parallel to the axis of the fermentation barrel is the pitch of the spiral line of the arrangement direction of the fixed plates themselves. This makes the arrangement of the fixed plates more regular, and further makes the acting force received by the fermentation barrel more uniform during the process of turning the fertilizer raw materials, improving the stability of the fermentation barrel during operation.

[0010] Optionally, a linkage assembly is arranged on the fermentation barrel. The linkage assembly includes a worm and worm gear group and a linkage rod. The worm and worm gear group is arranged in multiple groups corresponding to the movable plates, and multiple worm and worm gear groups are arranged corresponding to the multiple movable plates in the same group; the linkage rod is arranged along the direction parallel to the axis of the fermentation barrel and is rotatably connected to the fermentation barrel. The worm and worm gear group is located between the movable plates and the linkage rod for transmitting power, and the rotation of the linkage rod can drive the multiple movable plates to rotate.

[0011] By adopting the above technical solution, the power transmission between the linkage rod and multiple movable plates is realized through the linkage rod and the worm and worm gear set, which facilitates the linkage rod to control the rotation of the multiple movable plates and facilitates the staff to adjust the positions of the movable plates.

[0012] Optionally, the worm and worm gear set includes a worm wheel and a worm. The worm wheel meshes with the worm and is rotatably connected to the fermentation barrel. The worm wheel is fixedly connected to the movable plate, and the worm is fixedly connected to the linkage rod.

[0013] By adopting the above technical solution, the rotation of the linkage rod drives the rotation of the worm, and then drives the rotation of the worm wheel meshing with it, realizing the adjustment of the position of the movable plate. At the same time, the self-locking property of the threaded part is utilized to limit the movable plate, improving the stability of the movable plate during use.

[0014] Optionally, a driving assembly is arranged at one end of the linkage rod. The driving assembly includes a mounting frame, driving arc plates and a driving gear. The driving gear is fixed on the linkage rod. Two driving arc plates are provided. Both driving arc plates are slidably arranged on the mounting frame along the length direction of the fermentation barrel. Tooth grooves are arranged on the driving arc plates. Sliding different driving arc plates can connect different driving arc plates with the driving gear, and when different driving arc plates are connected with the driving gear, the driving gear can be driven to rotate in different directions.

[0015] By adopting the above technical solution, during the rotation of the fermentation barrel, the driving gear is driven. When the driving gear moves to the position corresponding to the driving arc plate, one of the driving arc plates can be meshed with the driving gear. At this time, as the fermentation barrel rotates, the driving gear can roll relative to the driving arc plate, thereby driving the rotation of the linkage rod and realizing the driving of the linkage rod.

[0016] Optionally, two driving arc plates are provided, and the radii of the two driving arc plates are different. The driving gear is arranged between the two driving arc plates.

[0017] By adopting the above technical solution, the driving gear is arranged between the two driving arc plates, and the two driving arc plates drive the driving gear to rotate from different sides of the driving gear, realizing the driving of the linkage rod to rotate in different directions, and further realizing the driving of the movable plate to rotate in different directions.

[0018] Optionally, the driving assembly further includes a driving column. The driving column is arranged between the two driving arc plates. Driving pins are arranged on the driving arc plates, and driving grooves are arranged on the driving column. The driving pins are inserted into the driving grooves, and rotating the driving column can drive the two driving arc plates to slide in opposite directions.

[0019] By adopting the above technical solution, the driving column drives the two driving arc plates to move in opposite directions. While controlling the two driving arc plates, only one driving arc plate meshes with the driving gear at the same moment, reducing the situation of jamming between the driving gear and the driving arc plates.

[0020] Optionally, the driving groove is connected end to end around the driving column.

[0021] By adopting the above technical solution, the driving groove is connected end to end to form an annular structure, enabling the driving column to rotate in a cycle rather than reciprocally drive the driving arc plate to move, which is convenient for controlling the driving column.

[0022] Optionally, a sliding groove is provided on the side wall of the material port. The sliding groove includes an axial portion with a length direction parallel to the axis of the fermentation barrel and a radial portion with a length direction perpendicular to the axial portion. A bolt is provided on the sealing door, and one end of the bolt is inserted into the sliding groove and can slide along the length direction of the sliding groove.

[0023] By adopting the above technical solution, the sliding groove includes an axial portion and a radial portion, which are connected to form an L-shaped structure. The bolt can slide along the length direction of the sliding groove, so that the sealing door can move away from the end cover along the axis direction of the fermentation barrel and can move away from the material hole along the direction of the radial portion, facilitating the sealing and opening of the material port.

[0024] Optionally, the fermentation barrel is provided with an end cover. The material port is arranged on the end cover and is located on one side of the axis of the end cover, and an opening is formed on the side wall of the end cover; the end cover is rotatably connected to the frame and can rotate relative to the fermentation barrel.

[0025] By adopting the above technical solution, the rotation of the end cover can change the position of the material port in the vertical direction. When the material port is located below, it is convenient for the discharge of chemical fertilizers. When the material port is located above, it is convenient for the feeding of chemical fertilizer raw materials, realizing the multi-functional use of the material port.

Detailed implementation manners

[0034] The following further describes the present application in detail with reference to the attached Figure 1-7 drawings.

[0035] An embodiment of the present application discloses a rice straw recycling composting fermentation device.

[0036] Referring to Figure 1 and Figure 2 , a rice straw recycling composting fermentation device includes a fermentation barrel 1 and a frame 2; the fermentation barrel 1 is a cylindrical shell structure with a hollow interior, and the fermentation barrel 1 is horizontally arranged and rotatably connected to the frame 2 around its own axis. One side of the fermentation barrel 1 is open, and an end cover 11 is provided at the opening. A material port 12 is provided on the end cover 11, and the material port 12 is blocked by a blocking door 13 movably connected to the end cover 11. The opening and closing of the material port 12 can be controlled by the movable blocking door 13. Chemical fertilizer raw materials can be placed into the fermentation barrel 1 through the material port 12 for fermentation. When it is necessary to stir and turn the chemical fertilizer raw materials, the fermentation barrel 1 is rotated; the chemical fertilizer raw materials in the fermentation barrel 1 are turned over under the action of their own gravity, so as to realize the rapid turning of the whole chemical fertilizer raw materials and improve the turning efficiency of the chemical fertilizer raw materials.

[0037] Referring to Figure 2 and Figure 3, a stirring assembly 3 is also provided in the fermentation barrel 1. The stirring assembly 3 includes a fixed plate 31 and a movable plate 32. The fixed plates 31 are provided in multiple numbers, and the multiple fixed plates 31 are arranged at intervals in a direction parallel to the axis of the fermentation barrel 1. The fixed plate 31 is in a spiral plate-like structure, and its outer side wall is welded to the inner side wall of the fermentation barrel 1, and its extending direction coincides with the direction of its own arrangement. The movable plate 32 is also in a spiral plate-like structure. The movable plate 32 is arranged corresponding to the gap between two adjacent fixed plates 31. The two ends of the movable plate 32 extend towards the direction close to the two fixed plates 31 respectively, and the movable plate 32 is tangent to the two fixed plates 31. The movable plate 32 can jointly form a spiral plate-like structure with the fixed plate 31.

[0038] Refer to Figure 2 and Figure 3 , the middle position in the length direction of the movable plate 32 is rotatably connected to the fermentation barrel 1. The rotation axis of the movable plate 32 is perpendicular to the axis of the fermentation barrel 1. Rotating the movable plate 32 can make the two ends of the movable plate 32 away from the fixed plate 31. As the movable plate 32 rotates continuously, the angle between the movable plate 32 and the fixed plate 31 changes. When the inclination directions of the fixed plate 31 and the movable plate 32 are opposite, this state is defined as the stirring state. In the stirring state, the fermentation barrel 1 rotates, the fixed plate 31 drives the material close to the material port 12, while the movable plate 32 drives the fertilizer raw material away from the material port 12, realizing the reciprocating turning of the fertilizer raw material in the axial direction of the fermentation barrel 1. The state when the two ends of the movable plate 32 are connected to the two ends of the fixed plate 31 is defined as the discharging state. In the discharging state, the movable plate 32 and the fixed plate 31 are connected to each other to form a spiral structure. In the discharging state, when the fermentation barrel 1 rotates, it can drive the material close to the material port 12 and discharge it.

[0039] Refer to Figure 2 and Figure 3 , the outer side wall of the movable plate 32 is spaced from the side wall of the fermentation barrel 1 to facilitate the rotation of the movable plate 32. A flexible member 33 is provided on the outer side wall of the movable plate 32. The flexible member 33 is bonded to the outer side wall of the movable plate 32 and can abut against the inner side wall of the fermentation barrel 1. The gap between the movable plate 32 and the fermentation barrel 1 is blocked by the flexible member 33, which is convenient for driving the movement of the fertilizer raw material. At the same time, due to its own flexibility, it can adapt to the rotation of the movable plate 32 and reduce the situation of jamming during the rotation of the movable plate 32.

[0040] Refer to Figure 2 and Figure 3, the projections of multiple fixing plates 31 on a plane perpendicular to their own axes can be divided into multiple groups, and the multiple groups of fixing plates 31 are evenly spaced along the circumference of the fermentation barrel 1. It can also be understood that the projections of the fermentation plates in the same group coincide on a plane perpendicular to the axis of the fermentation barrel 1. In this embodiment, a total of seven fixing plates 31 are provided. Among them, one group of fixing plates 31 includes four fixing plates 31, and the other group includes three fixing plates 31. And the movable plates 32 are provided in two groups corresponding to the gaps between two adjacent groups of fixing plates 31. The movable plates 32 in the same group are evenly spaced in the axial direction of the fermentation barrel 1, and the fixing plates 31 in the same group are also evenly spaced in the axial direction of the fermentation barrel 1.

[0041] Referring to Figure 1 and Figure 4 , a linkage assembly 4 is provided on the outer side wall of the fermentation barrel 1. The linkage assembly 4 includes a worm and worm gear set 41 and a linkage rod 42. Multiple worm and worm gear sets 41 are provided corresponding to multiple groups of movable plates 32, and multiple worm and worm gear sets 41 are provided corresponding to each movable plate 32 in each group. The linkage rod 42 is a cylindrical rod-shaped structure. The linkage rod 42 is arranged parallel to the fermentation barrel 1 and is rotatably connected to the fermentation barrel 1 around its own axis. Multiple linkage rods 42 are also provided corresponding to multiple groups of movable plates 32. The linkage rod 42 is connected to multiple worm and worm gear sets 41 in the same group. The rotation of the linkage rod 42 can drive the rotation of multiple movable plates 32 to realize the synchronous adjustment of multiple movable plates 32.

[0042] Referring to Figure 1 and Figure 4 , the worm and worm gear set 41 includes a worm wheel and a worm. The worm wheel is rotatably connected to the fermentation barrel 1 and is fixedly connected to the movable plate 32. The worm is rotatably connected to the outer side wall of the fermentation barrel 1, and the worms of multiple worm and worm gear sets 41 in the same group are coaxially arranged. The worm is coaxially welded to the linkage rod 42 to realize the drive of the linkage rod 42 for multiple worm wheels.

[0043] Referring to Figure 4 and Figure 5 , a driving assembly 5 is provided at one end of the linkage rod 42. The driving assembly 5 includes a mounting frame 51 and a driving arc plate 52. The mounting frame 51 is fixed on the machine frame 2 or sits on the ground. In this embodiment, the mounting frame 51 sits on the ground. The driving arc plate 52 is an arc-shaped structure, and two driving arc plates 52 are provided. The radii of the two driving arc plates 52 are different. The driving arc plate 52 with a larger diameter is defined as the outer driving plate 521, and the driving arc plate 52 with a smaller radius is defined as the inner driving plate 522. The linkage rod 42 is arranged between the inner driving plate 522 and the outer driving plate 521.

[0044] Referring to Figure 4 and Figure 5, the driving assembly 5 further includes a driving gear 57, and the driving gear 57 is coaxially welded to the linkage rod 42. Tooth grooves capable of meshing with the driving gear 57 are provided on the inner side wall of the outer driving plate 521, and tooth grooves capable of meshing with the driving gear 57 are provided on the outer side wall of the inner driving plate 522. Both the inner driving plate 522 and the outer driving plate 521 are slidably connected to the fermentation barrel 1 in a direction parallel to the axis of the fermentation barrel 1. During the rotation of the fermentation barrel 1, the linkage rod 42 is driven to move around the axis of the fermentation barrel 1. When it is necessary to adjust the angle of the movable plate 32, the inner driving plate 522 or the outer driving plate 521 is slid to move it in a direction closer to the linkage rod 42. After the fermentation barrel 1 drives the linkage rod 42 to move to a position corresponding to the inner driving ring or the outer driving ring, the linkage rod 42 can be driven to rotate under the action of the gear and the tooth groove, realizing the adjustment of the position of the movable plate 32. The rotation direction of the movable plate 32 is controlled by the inner driving plate 522 and the outer driving plate 521. Specifically, engaging the outer driving plate 521 with the driving gear 57 can drive the linkage rod 42 to rotate in one direction, and when the inner driving plate 522 is engaged with the driving gear 57, the linkage rod 42 can be driven to rotate in the other direction.

[0045] Referring to Figure 4 and Figure 5 , the driving assembly 5 further includes a driving column 53. The driving column 53 is of a cylindrical structure, is horizontally arranged, and is rotatably connected to the mounting bracket 51. Connecting plates 54 are welded to the inner driving plate 522 and the outer driving plate 521. The two connecting plates 54 are parallel to each other, and the driving column 53 is arranged between the two connecting plates 54. Driving pins 55 are provided on the side surfaces of the connecting plates 54 close to the driving column 53. An annular driving groove 56 is formed on the side wall of the driving column 53. One end of the driving pin 55 away from the connecting plate 54 is inserted into the driving groove 56 and can slide along the length direction of the driving groove 56.

[0046] Referring to Figure 4 and Figure 5 , the driving groove 56 includes a forward groove 561 and a reverse groove 562. The forward groove 561 includes a stable part 5611 and a driving part 5612. There are two driving parts 5612. The driving parts 5612 and the stable part 5611 are arranged in sequence along the circumferential direction of the driving column 53, and the stable part 5611 is arranged between the two driving parts 5612. The two ends of the driving part 5612 are inclined in a direction away from the linkage rod 42. Under the cooperation of the driving part 5612 and the driving pin 55, when the driving groove 56 moves in the driving part 5612 in a direction closer to the stable part 5611, the outer driving plate 521 or the inner driving plate 522 can be driven to approach the linkage rod 42.

[0047] Referring to Figure 4 and Figure 5, the reverse slot 562 has the same structure as the forward slot 561. The stabilizing portions 5611 of the reverse slot 562 are spaced apart axially of the drive post 53 from the stabilizing portions 5611 of the forward slot 561. One end of the driving portion 5612 of the reverse slot 562 communicates with the stabilizing portion 5611, and the other end extends towards the direction close to the forward slot 561. The driving portions 5612 of the reverse slot 562 and the forward slot 561 communicate with each other to form a complete annular structure. During the rotation of the drive post 53, the drive pin 55 moves cyclically relative to the drive post 53 in the drive slot 56, thereby driving the inner drive plate 522 and the outer drive plate 521 to move in opposite directions. In this embodiment, the drive post 53 is driven by a servo motor.

[0048] Referring to Figure 6 and Figure 7 , a sliding slot 6 is formed in the side wall of the material inlet 12. The sliding slot 6 includes an axial portion 61 and a radial portion 62. The axial portion 61 is arranged parallel to the axis of the fermentation barrel 1, the radial portion 62 is perpendicular to the circumferential portion, one end of the radial portion 62 communicates with the axial portion 61, and the other end extends towards the direction close to the axis of the fermentation barrel 1. A cylindrical plug 7 is welded to the side wall of the sealing door 13 corresponding to the sliding slot 6. One end of the plug 7 is inserted into the sliding slot 6 and can slide along the length direction of the sliding slot 6. When the sealing door 13 is in the state of sealing the material inlet 12, the plug 7 is located at one end of the axial portion 61 away from the radial portion 62. At this time, the sealing door 13 slides away from the fermentation barrel 1 to open the material inlet 12. When the plug 7 corresponds to the radial portion 62, the sealing door 13 can slide along the length direction of the radial portion 62. At this time, the sealing door 13 can further open the material inlet 12 to facilitate feeding or discharging.

[0049] Referring to Figure 6 and Figure 7, a sliding plate 8 for controlling the opening and closing of the sealing door 13 is arranged at a position corresponding to the material port 12 on the fermentation barrel 1. An installation groove is formed on the side wall of the material port 12 corresponding to the sliding groove 6, and the sliding plate 8 is slidably connected in the installation groove along a direction parallel to the length direction of the radial part 62. An inclined hole 9 is formed on the sliding plate 8, and the inclined hole 9 is inclined in a direction away from the inside of the fermentation barrel 1 from one side far away from the axis of the fermentation barrel 1 to the other side far away from the axis of the fermentation barrel 1 in a direction parallel to the radial part 62. One end of the inclined hole 9 corresponds to the end of the axial part 61 far away from the radial part 62, and the other end corresponds to the radial part 62. It can also be understood that the length of the inclined hole 9 in the direction of the axis of the fermentation barrel 1 is equal to the length of the axial part 61. The bolt 7 passes through the inclined hole 9 and is inserted into the sliding groove 6. By sliding the sliding plate 8, under the action of the inclined hole 9, the bolt 7 can be driven to slide along the length direction of the axial part 61. When the bolt 7 moves to one end of the inclined hole 9 far away from the inside of the fermentation barrel 1, continuing to slide the sliding plate 8 can drive the bolt 7 to move along the length direction of the radial part 62, realizing the driving of the sealing door 13. The sliding of the sliding plate 8 can be driven by a hydraulic cylinder or an electric push rod. In this embodiment, the movement of the sliding plate 8 is driven by an electric push rod (not shown in the figure).

[0050] Referring to Figure 6 and Figure 7 , in order to improve the stability of the sealing door 13 during movement, a plurality of sliding grooves 6 can be arranged along the length direction of the radial part 62. In this embodiment, two are arranged, and the bolt 7 and the inclined hole 9 are correspondingly arranged in two for the sliding groove 6. In order to further improve the stability of the sealing door 13 for sealing the material port 12, two sliding plates 8 can be arranged corresponding to two mutually parallel side surfaces of the material port 12.

[0051] Referring to Figure 1 , the end cover 11 is rotatably connected to the frame 2 and can rotate relative to the fermentation barrel 1; the material port 12 is located on one side of the axis of the end cover 11, and an opening is formed on the side wall of the end cover 11. Rotating the end cover 11 can change the position of the material port 12. When the position of the material port 12 is above the axis of the fermentation barrel 1, it is convenient to feed materials into the fermentation barrel 1. When the material port 12 is below the axis of the fermentation barrel 1, it is convenient to discharge the chemical fertilizer in the fermentation barrel 1.

[0052] Specifically, an arc-shaped support plate 10 is arranged on the frame 2, and an arc-shaped wedge block 101 is arranged on the end cover 11; an arc-shaped groove is formed on the support plate 10 corresponding to the wedge block 101, and the wedge block 101 is slidably matched in the arc-shaped groove to realize the rotational connection between the end cover 11 and the frame 2.

[0053] The implementation principle of a rice straw recycling compost fermentation device in an embodiment of the present application is as follows: By rotating the fermentation barrel 1, the materials inside the fermentation barrel 1 can automatically turn under the action of their own gravity, so as to quickly turn all the materials inside the fermentation barrel 1, improve the efficiency of stirring the fertilizer raw materials, and at the same time avoid the stirring of the stirring rod, thereby improving the overall service life of the fermentation device.

[0054] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
