Description

Technical Field

[0001] The utility model relates to a stirring mixer, in particular to an automatic stirring mixer for the production of biological organic fertilizers applied to the field of material mixing equipment. Background Art

[0002] An automatic stirring mixer for the production of biological organic fertilizers is a device specifically used for stirring and mixing various raw materials during the production process of biological organic fertilizers. The stirring container is the part that holds the raw materials of biological organic fertilizers, usually cylindrical or trough-shaped. The stirring shaft is a component that transmits power and drives the stirring blades to rotate. The stirring shaft needs to have sufficient strength and stiffness to withstand the torque during the stirring process.

[0003] The specification of Chinese Patent CN210544507U discloses a horizontal double-shaft fertilizer stirring device, including a stirring device main body, a cross plate, a transmission device, a motor, a feed inlet, a dust-proof net, a first stirring column, a second stirring column, and a discharge outlet. The feed inlet is provided on the stirring device main body, and the dust-proof net is provided on the feed inlet. The first stirring column and the second stirring column are provided inside the stirring device main body. Compared with the prior art, the utility model has a simple structure and reasonable design. The double-screw stirring column is driven by the motor to fully stir the fertilizer, greatly increasing the stirring efficiency and effect, and the components of the stirred fertilizer are uniform.

[0004] When an automatic stirring mixer for the production of biological organic fertilizers processes easily caking materials, if the caking materials cannot be broken up, the distribution of microorganisms in the materials will also be uneven, affecting the function of microorganisms in the soil. Therefore, in order to break up and mix the caking materials as much as possible, it may be necessary to extend the stirring time, which will reduce the efficiency of the entire production process. Therefore, it is necessary to design an automatic stirring mixer for the production of biological organic fertilizers with an auxiliary material scattering mechanism to solve the above problems. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that when an automatic stirring mixer for the production of biological organic fertilizers processes easily caking materials, if the caking materials cannot be broken up, the distribution of microorganisms in the materials will also be uneven, affecting the function of microorganisms in the soil. Therefore, in order to break up and mix the caking materials as much as possible, it may be necessary to extend the stirring time, which will reduce the efficiency of the entire production process.

[0006] To solve the above problems, the present utility model provides an automatic stirring and mixing machine for the production of biological organic fertilizer, which includes a horizontal mixing tank. The lower end of the horizontal mixing tank is fixedly connected with a base bracket, and a grid cover plate is installed at the upper end of the horizontal mixing tank. A pair of motor drivers are arranged at the front end of the base bracket, and the output end of the motor driver extends into the horizontal mixing tank. The output end of the motor driver is fixedly connected with an inner pair of rotating roller shafts, and a plurality of mixing components are fixedly connected to the outer ends of the inner pair of rotating roller shafts. The mixing component includes three fixing blocks arranged at equal intervals in a ring shape. The mixing component includes a plurality of helically arranged and inclined blades fixedly connected to the outside of the inner pair of rotating roller shafts. One end of the fixing block away from the inner pair of rotating roller shafts is threadedly connected with a material breaking fan blade, and a milling tooth panel layer is arranged at one end of the material breaking fan blade away from the inner pair of rotating roller shafts. The two inner pair of rotating roller shafts cooperate with each other, and a plurality of self-rotating tooth surface sleeve rings arranged at equal intervals are rotatably connected to the outer ends of the inner pair of rotating roller shafts;

[0007] A plurality of groups of guiding components are arranged at intervals at the outer ends of the inner pair of rotating roller shafts. The guiding component includes a connecting rod fixedly connected to the outside of the inner pair of rotating roller shafts. One end of the connecting rod away from the guiding component is fixedly connected with a screening mesh. A hollow back mesh is fixedly connected to the outer side wall of the screening mesh. An inclined feeding surface is fixedly connected to one end of the screening mesh close to the inner pair of rotating roller shafts, and an opening is arranged at one end of the screening mesh close to the material breaking fan blade.

[0008] In the above automatic stirring and mixing machine for the production of biological organic fertilizer, in the present solution, an inner pair of rotating roller shafts can be additionally arranged outside the material breaking fan blade during the mixing process of the two inner pair of rotating roller shafts. The milling tooth panel layer is in contact with the self-rotating tooth surface sleeve rings outside the inner pair of rotating roller shafts. Under the action of the mixing components, the mixing can be completed in a relatively short time, thereby improving the production efficiency.

[0009] As a further improvement of the present application, a buffer mechanism is arranged at the inner end of the self-rotating tooth surface sleeve ring. The buffer mechanism includes four liquid storage inner cavities opened on the inner side of the self-rotating tooth surface sleeve ring. One end of a plurality of adjacent liquid storage inner cavities is fixedly connected with a partition plate. One end of the partition plate is fixedly connected with a solenoid valve block. A number of oil liquids are filled in the inner end of the liquid storage inner cavity. A drain valve port is fixedly connected to the lower end of the self-rotating tooth surface sleeve ring. A plurality of reinforcing inner plates are fixedly connected to the inner end of the liquid storage inner cavity, and an opening is arranged in the middle of the inner end of the reinforcing inner plate.

[0010] As a further improvement of the present application, a plurality of self-rotating tooth surface sleeve rings are in contact with the milling tooth panel layer. An inner cavity layer is opened at one end of the material breaking fan blade away from the fixing block, and a displacement component is arranged in the inner cavity layer.

[0011] As a further improvement of the present application, the displacement component includes a telescopic sleeve rod arranged at the inner end of the inner cavity layer. The telescopic sleeve rod includes a pair of telescopic sleeve rods fixedly connected to the inner side wall of the inner cavity layer.

[0012] As another improvement of the present application, one end of the telescopic sleeve rod away from the material-breaking fan blade is connected to the milling tooth panel layer, and a pair of electric magnetic inner blocks are fixedly connected to the inner side wall of the inner cavity layer away from the milling tooth panel layer.

[0013] As a supplement to another improvement of the present application, the electric magnetic inner block is magnetically connected to the milling tooth panel layer, and guiding side chutes are symmetrically arranged on the two inner walls of the inner cavity layer.

[0014] As a supplement to another improvement of the present application, one end of the milling tooth panel layer close to the guiding side chute is fixedly connected with side sliders, and the two side sliders are slidably connected in the corresponding guiding side chutes.

[0015] In summary, in the process of mixing by the two inner counter-rotating roller shafts in this solution, an inner counter-rotating roller shaft can be additionally arranged outside the material-breaking fan blade. The milling tooth panel layer is in contact with the self-rotating tooth surface ring outside the inner counter-rotating roller shaft. When the milling tooth panel layer and the self-rotating tooth surface ring rotate, a strong milling pressure between gears is generated between the milling tooth panel layer and the self-rotating tooth surface ring. Under the action of the mixing assembly, the mixing can be completed in a relatively short time, thereby improving the production efficiency. And when the self-rotating tooth surface ring and the milling tooth panel layer cooperate, a connecting rod can be arranged on one side of the self-rotating tooth surface ring and the milling tooth panel layer. The connecting rod rotates with the inner counter-rotating roller shaft in the horizontal mixing tank, and when contacting the material, the large-particle agglomerates are screened out by the hollow back net in the buffer mechanism of the guiding assembly, and when the screening net rotates to directly above the material-breaking fan blade, the stored material in it falls along the inclined feeding surface through the opening to the range on one side close to the material-breaking fan blade, making the treatment effect of the milling tooth panel layer and the self-rotating tooth surface ring on the agglomerates in the material body more accurate and the mixing effect better.

Specific embodiments

[0026] The following describes the two embodiments of the present application in detail with reference to the accompanying drawings.

[0027] The first embodiment:

[0028] Figures 1-7 An automatic stirring and mixing machine for producing biological organic fertilizer is shown, including a horizontal mixing tank 1. A base bracket 2 is fixedly connected to the lower end of the horizontal mixing tank 1. A grid cover plate 4 is installed at the upper end of the horizontal mixing tank 1. A pair of motor drivers 3 are arranged at the front end of the base bracket 2. The output end of the motor driver 3 extends into the horizontal mixing tank 1. The output end of the motor driver 3 is fixedly connected to an inner counter-rotating roller shaft 6. A plurality of mixing components 5 are fixedly connected to the outer end of the inner counter-rotating roller shaft 6. The mixing component 5 includes three fixed blocks 7 arranged at equal intervals in a ring shape. The mixing component 5 includes a plurality of helically arranged inclined blades 24 fixedly connected to the outside of the inner counter-rotating roller shaft 6. One end of the fixed block 7 away from the inner counter-rotating roller shaft 6 is threadedly connected to a material-breaking fan blade 9. One end of the material-breaking fan blade 9 away from the inner counter-rotating roller shaft 6 is provided with a milling tooth panel layer 8. The two inner counter-rotating roller shafts 6 cooperate with each other. A plurality of self-rotating tooth surface rings 10 arranged equidistantly from the front are rotatably connected to the outer end of the inner counter-rotating roller shaft 6;

[0029] At the outer end of the inner counter-rotating roller shaft 6, there are multiple groups of guiding components 25 arranged at intervals. The guiding component 25 includes a connecting rod 26 fixedly connected to the outside of the inner counter-rotating roller shaft 6. One end of the connecting rod 26 away from the guiding component 25 is fixedly connected with a screening mesh 27. The outer side wall of the screening mesh 27 is fixedly connected with a hollowed-back mesh 28. One end of the screening mesh 27 close to the inner counter-rotating roller shaft 6 is fixedly connected with an inclined feeding surface 29. An opening 30 is formed at one end of the screening mesh 27 close to the material-breaking fan blade 9.

[0030] Figures 1-7 It is shown that a buffer mechanism 17 is arranged at the inner end of the self-rotating tooth surface sleeve 10. The buffer mechanism 17 includes four liquid storage inner cavities 20 opened on the inner side of the self-rotating tooth surface sleeve 10. One end of the adjacent multiple liquid storage inner cavities 20 is fixedly connected with a partition plate 18. One end of the partition plate 18 is fixedly connected with a solenoid valve block 19. The inner end of the liquid storage inner cavity 20 is filled with a number of oil liquids. The lower end of the self-rotating tooth surface sleeve 10 is fixedly connected with a liquid discharge valve port 23. The inner end of the liquid storage inner cavity 20 is fixedly connected with multiple reinforcing inner plates 21. An opening 22 is formed in the middle of the inner end of the reinforcing inner plate 21. Multiple self-rotating tooth surface sleeves 10 are in contact with the milling tooth panel layer 8.

[0031] Figures 1-7 It is shown that in this solution, the biological organic fertilizer raw materials and other additives are all put into the horizontal mixing tank 1. The motor driver 3 drives the inner counter-rotating roller shafts 6 to rotate in opposite directions in the horizontal mixing tank 1, so that the biological organic fertilizer raw materials and other additives are fully mixed in the horizontal mixing tank 1. During the mixing process, the biological organic fertilizer raw materials and other additives will be subjected to shearing, extrusion, rolling and other actions, so as to achieve uniform distribution. At the same time, during the mixing process of the two inner counter-rotating roller shafts 6, an inner counter-rotating roller shaft 6 can be additionally arranged outside the material-breaking fan blade 9. The milling tooth panel layer 8 is in contact with the self-rotating tooth surface sleeve 10 on the outside of the inner counter-rotating roller shaft 6. When the milling tooth panel layer 8 and the self-rotating tooth surface sleeve 10 rotate, a strong milling pressure between the gears is generated between the milling tooth panel layer 8 and the self-rotating tooth surface sleeve 10, so as to easily break up the lumps during the mixing process and break them into smaller qualified particles, making the mixing degree of each raw material higher. Under the action of the mixing component 5, the mixing can be completed in a shorter time, thus improving the production efficiency. And when the self-rotating tooth surface sleeve 10 and the milling tooth panel layer 8 cooperate, a connecting rod 26 can be arranged on one side of the self-rotating tooth surface sleeve 10 and the milling tooth panel layer 8. The connecting rod 26 rotates with the inner counter-rotating roller shaft 6 in the horizontal mixing tank 1, and when contacting the material, the hollowed-back mesh 28 in the buffer mechanism 17 of the guiding component 25 is used to screen out the large-particle agglomerates, and when the screening mesh 27 rotates to directly above the material-breaking fan blade 9, the stored material in it falls along the inclined feeding surface 29 through the opening 30 and drops into the range on one side close to the material-breaking fan blade 9, making the treatment effect of the milling tooth panel layer 8 and the self-rotating tooth surface sleeve 10 on the agglomerates in the material body more accurate and the mixing effect better.

[0032] A buffer mechanism 17 can be provided on the self-rotating tooth surface ring 10. The buffer mechanism 17 consists of four liquid storage cavities 20 that are annularly and equidistantly arranged inside the self-rotating tooth surface ring 10. When the self-rotating tooth surface ring 10 is subjected to impact force or uneven pressure during operation, the oil in the liquid storage cavities 20 can play a certain shock absorption and buffering role. The compressibility and fluidity of the oil can absorb part of the impact energy, reduce the vibration damage between the self-rotating tooth surface ring 10 and the abrasive tooth panel layer 8, and thus improve the service life of the overall mechanism. When it is necessary to drain and update the oil in the liquid storage cavities 20, the external control terminal can open multiple solenoid valve blocks 19 together, making the multiple liquid storage cavities 20 in a connected state. The oil inside can flow into the drain valve port 23 at the bottom by gravity and be discharged. The oil can be discharged through a unified path, and the drainage method is more convenient. The liquid injection method can be used to supplement the liquid through the liquid injection holes. In addition, a reinforcing inner plate 21 is provided in the liquid storage cavity 20. The reinforcing inner plate 21 divides the liquid storage cavity 20 into smaller spaces, and the openings 22 in the reinforcing inner plate 21 can improve the strength of the liquid storage cavity 20, while reducing the impact force of the liquid on the liquid storage cavity 20 and improving the stability of the multiple liquid storage cavities 20 during operation in the self-rotating tooth surface ring 10.

[0033] The second implementation method:

[0034] Figures 7-8An automatic stirring and mixing machine for the production of biological organic fertilizer is shown. An inner cavity layer 15 is provided at one end of the material-breaking fan blade 9 far away from the fixed block 7. A displacement component 11 is arranged in the inner cavity layer 15. The displacement component includes a telescopic sleeve rod 16 arranged at the inner end of the inner cavity layer 15. The telescopic sleeve rod 16 includes a pair of telescopic sleeve rods 16 fixedly connected to the inner side wall of the inner cavity layer 15. The end of the telescopic sleeve rod 16 far away from the material-breaking fan blade 9 is connected to the material-grinding tooth panel layer 8. A pair of electric magnetic inner blocks 14 are fixedly connected to the inner side wall of the inner cavity layer 15 far away from the material-grinding tooth panel layer 8. The electric magnetic inner blocks 14 are magnetically connected to the material-grinding tooth panel layer 8. Guide side chutes 12 are symmetrically arranged on the two inner walls of the inner cavity layer 15. One end of the material-grinding tooth panel layer 8 close to the guide side chutes 12 is fixedly connected with side sliders 13. The two side sliders 13 are slidably connected in the corresponding guide side chutes 12. At the same time, during the working process of the material-grinding tooth panel layer 8, a displacement component 11 can be arranged between the material-breaking fan blade 9 and the material-grinding tooth panel layer 8. The displacement component 11 can make the electric magnetic inner blocks 14 therein energized. After being energized, the displacement component 11 retracts, so that the telescopic sleeve rod 16 is extruded. After being extruded, the material-grinding tooth panel layer 8 can be retracted into the inner cavity layer 15. When producing fertilizers that are not easy to agglomerate, the displacement component 11 can be made not to contact the self-rotating tooth surface ring 10, so that unnecessary friction is not generated between the two during this process, making the use of the mixing component 5 more flexible and controllable, reducing the equipment investment cost and operation cost. At the same time, when the displacement component 11 retracts through the electric magnetic inner blocks 14, the guide side chutes 12 on both sides thereof can slide in the side sliders 13, playing a role of support and positioning, so that the displacement path of the material-grinding tooth panel layer 8 can be stably controlled, thereby improving the stability and reliability of the whole device.

[0035] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
