Description

Technical Field

[0001] The invention belongs to the technical field of fermentation equipment, and in particular relates to fertilizer production fermentation equipment. Background Art

[0002] Organic fertilizers generally need to be fermented before use. Fermentation is a process in which organic matter is continuously degraded and stabilized by the action of microorganisms under certain conditions, and a product suitable for land use is produced. At present, in the preparation process of organic fertilizers, fermentation bacteria are mostly used to ferment fertilizer raw materials. However, since most of the raw materials of organic fertilizers are solid-liquid mixtures, the contact between the fermentation bacteria and the raw materials is insufficient, so the fermentation is incomplete. If the fermentation is incomplete, the fertilizer will have a very strong odor. In addition, the bottom layer of the fertilizer is densely piled, the oxygen content is too low, and the fermentation activity of oxygen-loving microorganisms is weakened, which prolongs the fermentation cycle and affects the fermentation efficiency and effect of the organic fertilizer.

[0003] Existing fertilizer production and fermentation equipment includes a fermentation tank, a rotating mechanism and a stirring rod. Switch valves for feeding and discharging are respectively provided on both sides of the fermentation tank. The stirring rod is arranged inside the fermentation tank. The rotating mechanism drives the fermentation tank or the stirring rod to rotate, thereby achieving mixing of the fermented material in the fermentation tank. When the fermentation tank rotates, the stirring rod does not rotate, and when the stirring rod rotates, the fermentation tank does not rotate, so that the fermented material can be fully mixed.

[0004] Although the existing equipment has the function of mixing fermented products, for fermented products that require high mixing efficiency, relying solely on the rotation of the fermentation tank or the rotating rod can barely meet the mixing requirements, but this method has poor mixing efficiency, resulting in a long entire fermentation cycle, which is not conducive to the efficient production of fertilizers, and is not conducive to the rapid discharge of heat generated during fermentation and fermentation air.

[0005] Therefore, in view of the above situation, it is urgent to develop a fertilizer production fermentation equipment to overcome the shortcomings in current practical applications. Summary of the invention

The rotating component cooperates with the rotational power of another output of the transmission mechanism through lateral movement. The transmission mechanism drives the rotating component to rotate in the opposite direction. The rotating component drives the central axis to rotate forward through the cavity. The central axis drives the spiral blades to rotate forward to transfer the fermentation material from the other end of the fermentation box to one end. The spiral blades quickly mix the fermentation material in the fermentation box through reciprocating rotation and cooperation with the rotating mechanism.

[0028] like Figures 1 to 8 As shown, a fertilizer production fermentation device provided as an embodiment of the present invention includes an equipment frame 1, and side covers 2 with a U-shaped cross section are fixed at both ends of the equipment frame 1. A fermentation box 3 is rotatably installed between the two side covers 2. A feed inlet 4 and a discharge port 5 are respectively opened at both ends of the fermentation box 3. A rotating mechanism 6 for driving the fermentation box 3 to rotate is also installed on the equipment frame 1, and further includes: A central shaft 7, the central shaft 7 is located in the fermentation box 3 and is concentric therewith, the two ends of the central shaft 7 are rotatably mounted on the side walls of the two ends of the fermentation box 3, the outer wall of the central shaft 7 is mounted with a spiral blade 8, and a cavity 71 is opened in the middle of the central shaft 7; A transmission mechanism 10, one end of which is concentric with and fixedly connected to a side wall of one end of the fermentation box 3, and the other end of which is mounted on the inner wall of the side cover 2; The control mechanism 9 includes a rotating assembly 91, a limit assembly 92 and a control assembly 93. One end of the rotating assembly 91 is slidably mounted on the inner wall of one side cover 2 and connected to the other end of the transmission mechanism 10. The other end of the rotating assembly 91 passes through the cavity 71 and is slidably connected to the inner wall of the other side cover 2. The rotating assembly 91 is connected to the transmission mechanism 10 and the inner wall of the cavity 71 respectively. The limiting component 92 is installed on the inner wall of one side cover 2 and is slidably matched with one end of the rotating component 91 . The variable control component 93 is arranged in the cavity 71 and is slidably connected with the rotating component 91 .

[0029] In this embodiment, the rotating mechanism 6 drives the fermentation box 3 to rotate on the side cover 2, and the rotation direction remains unchanged. The fermentation box 3 drives the transmission mechanism 10 to rotate, and the transmission mechanism 10 outputs two rotational forces in opposite directions. When the rotating assembly 91 cooperates with the rotational power outputted by one of the transmission mechanisms 10, the transmission mechanism 10 drives the rotating assembly 91 to rotate forward, and the rotating assembly 91 drives the central shaft 7 to rotate reversely through the cavity 71. The central shaft 7 drives the spiral blades 8 to rotate reversely, so that the fermented material can be transferred from one end of the fermentation box 3 to the other end. At the same time, the rotating assembly 91 drives the variable control assembly 93 to slide horizontally in the cavity 71. When the variable control component 93 slides to the extreme position, the variable control component 93 applies a certain resistance to the rotational movement of the rotating component 91 and drives the rotating component 91 to move horizontally, so that the rotating component 91 cooperates with the rotational power output from the other end of the transmission mechanism 10. At this time, the transmission mechanism 10 drives the rotating component 91 to rotate in the opposite direction, and the rotating component 91 drives the central shaft 7 to rotate forward through the cavity 71. The central shaft 7 drives the spiral blade 8 to rotate forward, so that the fermented material can be transferred from the other end of the fermentation box 3 to one end.

[0030] In a preferred embodiment, the diameter of the spiral blade 8 is smaller than the inner diameter of the fermentation box 3, which can help the fermentation product to revolve more effectively with the fermentation box 3, and also facilitate the spiral blade 8 to drive the fermentation product to move back and forth.

[0031] like Figures 3 to 8 As shown, as a preferred embodiment of the present invention, the rotating assembly 91 includes a connecting member 911, a rotating shaft 913, a gear A 915, a gear B 916, an internal gear 917 and a mounting shaft 918, the connecting member 911 is fixedly connected to one end of the rotating shaft 913, and the two ends of the rotating shaft 913 are respectively slidably mounted on the inner walls of the two side covers 2, the connecting member 911 is located between the transmission mechanism 10, and both sides of the connecting member 911 are provided with conical surfaces that intermittently slide with the transmission mechanism 10, the rotating shaft 913 passes through the cavity 71, and the A gear A915 is laterally slidably connected to the other end of the rotating shaft 913, and the gear A915 is movably arranged on the inner wall of the other side cover 2. The gear A915 is meshed with one side of a gear B916, and the gear B916 is fixed on the mounting shaft 918.

[0032] like Figures 3 to 8 As shown, as a preferred embodiment of the present invention, the connecting member 911 preferably adopts an annular block structure, and two limit grooves 912 are symmetrically provided on the outer wall of the connecting member 911. The limit grooves 912 are slidably matched with the limit assembly 92, and a spiral groove 914 slidably connected to the other end of the variable control assembly 93 is provided on the outer wall of the rotating shaft 913 located in the cavity 71.

[0033] In this embodiment, the transmission mechanism 10 drives the connecting member 911 to rotate, the connecting member 911 drives the rotating shaft 913 to rotate, the rotating shaft 913 drives the gear A915 to rotate, and at the same time, the rotating shaft 913 drives the variable control assembly 93 to slide horizontally on the mounting shaft 918 through the spiral groove 914, the gear A915 drives the gear B916 and the mounting shaft 918 thereon to rotate, the gear B916 drives the central shaft 7 to rotate through the internal gear 917, and the central shaft 7 drives the spiral blades 8 thereon to rotate, thereby realizing the reciprocating transmission of the fermented material in the fermentation box 3, and then realizing the sufficient and rapid mixing of the fermented material, ensuring that every part of the material in the fermentation box 3 can evenly contact the fermentation microorganisms, shortening the fermentation cycle of the fertilizer, and improving the fermentation efficiency and fermentation quality of the fermentation equipment for the fertilizer.

[0034] In a preferred embodiment, the installation axis 918 is parallel to the opening direction of the cavity 71, and the installation axis 918 is parallel to the rotation axis 913; The connecting member 911, the rotating shaft 913, the gear A 915, the cavity 71 and the central axis 7 are all concentric.

[0035] like Figures 3 to 8 As shown, as a preferred embodiment of the present invention, the variable control assembly 93 includes a sliding member 931, a moving member 932 and a spring B933, one end of the sliding member 931 slidingly cooperates with the spiral groove 914, the other end of the sliding member 931 is fixed on the moving member 932, the moving member 932 is located in the cavity 71 and is slidably mounted on the mounting shaft 918, the two side walls of the moving member 932 intermittently conflict with the springs B933 fixed on both ends of the mounting shaft 918, and the two springs B933 are both located in the cavity 71.

[0036] In this embodiment, when the connecting member 911 cooperates with the rotational power outputted by one of the transmission mechanisms 10, the transmission mechanism 10 drives the connecting member 911 to rotate forward, the connecting member 911 drives the rotating shaft 913 to rotate forward, the rotating shaft 913 drives the gear A915 to rotate forward, and at the same time, the rotating shaft 913 drives the sliding member 931 to move laterally toward one end of the cavity 71 through the spiral groove 914, the sliding member 931 drives the moving member 932 to move laterally toward one end of the cavity 71, the gear A915 drives the gear B916 and the mounting shaft 918 thereon to rotate in the opposite direction, the gear B916 drives the central shaft 7 to rotate in the opposite direction through the internal gear 917, and the central shaft 7 drives the spiral blades 8 thereon to rotate in the opposite direction, so that the fermented material can be transferred from one end of the fermentation box 3 to the other end; When the moving member 932 moves to conflict with the spring B933 on one end of the installation shaft 918, the spiral groove 914 drives the moving member 932 to continue to move through the sliding member 931, and the moving member 932 squeezes the spring B933. At the same time, the spring B933 in the squeezing process will exert a certain resistance to the movement of the moving member 932. The moving member 932 transmits the resistance to the rotating shaft 913 through the sliding member 931. When the spring B933 is compressed to the limit position, the resistance it exerts on the moving member 932 will drive the rotating shaft 913 to move laterally. The rotating shaft 913 drives the connecting member 911 to move laterally, so that the connecting member 911 cooperates with the rotational power output from the other end of the transmission mechanism 10, thereby changing the rotation direction of the rotating shaft 913. At this time, the rotating shaft 913 drives the sliding member 931 to move in the opposite direction, and at the same time, drives the central shaft 7 to rotate forward. The central shaft 7 drives the spiral blade 8 thereon to rotate forward, so that the fermented material can be transferred from the other end of the fermentation box 3 to one end. The way of reciprocatingly changing the rotation direction of the rotating shaft 913 can make the central shaft 7 and the spiral blade 8 thereon rotate reciprocatingly. The spiral blade 8 can not only make the fermented material revolve with the fermentation box 3 through reciprocating rotation and cooperation with the rotating mechanism 6, but also make it reciprocate in the fermentation box 3, thereby achieving sufficient and rapid mixing of the fermented material, ensuring that every part of the material in the fermentation box 3 can evenly contact the fermentation microorganisms, shortening the fermentation cycle of the fertilizer, and improving the fermentation efficiency and fermentation quality of the fertilizer by the fermentation equipment.

[0039] In this embodiment, the spring A923 can drive the limiting member 921 to always conflict with the connecting member 911 and the limiting groove 912 thereon through its own elastic force. When the moving member 932 moves toward the connecting member 911, the limiting member 921 slides and cooperates with the limiting groove 912 on the connecting member 911 away from the moving member 932, so that the connecting member 911 can stably cooperate with the rotational power outputted by one of the transmission mechanisms 10. When the moving member 932 moves to the position, the resistance it applies to the rotating shaft 913 of the connecting member 911 is greater than the elastic force of the spring A923, so that the connecting member 911 squeezes the limiting member 921, and the limiting member 921 moves vertically, thereby separating the limiting member 921 from the limiting groove 912 on one side and releasing the limit on the connecting member 911, and the connecting member 911 and the rotating shaft 913 can be displaced laterally. By means of lateral displacement, the connecting member 911 can not only be separated from the rotating power outputted by one end of the transmission mechanism 10, but also cooperate with the rotating power outputted by the other end of the transmission mechanism 10; When the connecting member 911 cooperates with the rotational power output from the other end of the transmission mechanism 10, the limiting groove 912 on the other side of the connecting member 911 moves to cooperate with the limiting member 921. The limiting member 921 cooperates with the limiting groove 912 to limit the connecting member 911 again, so that the connecting member 911 can stably cooperate with the other rotational power output from the transmission mechanism 10.

At the same time, the spring B933 in the squeezing process will exert a certain resistance to the movement of the moving member 932. The moving member 932 transmits the resistance to the rotating shaft 913 through the sliding member 931. When the spring B933 is compressed to the limit position, the resistance it exerts on the moving member 932 will drive the rotating shaft 913 to move laterally.
