Description

Technical Field

[0001] This utility model relates to the field of bio-organic fertilizer production technology, specifically a bio-organic fertilizer fermentation tank turning device. Background Technology

[0002] Bio-organic fertilizer refers to a type of fertilizer that combines the effects of microbial fertilizer and organic fertilizer, made from specific functional microorganisms and organic materials mainly derived from animal and plant residues, such as livestock and poultry manure and crop straw, after harmless treatment and composting. Bio-organic fertilizer contains a complete range of nutrients, providing comprehensive nutrition for crops. The beneficial microorganisms within it form a symbiotic relationship with soil microorganisms, inhibiting the growth of harmful bacteria and transforming them into beneficial bacteria, thus promoting and regulating crop growth. Fermentation is a crucial step in the production of bio-organic fertilizer. Small and medium-sized production enterprises typically use fermentation tanks for fermentation, requiring intermittent turning during the process. Existing turning machines have poor aeration effects during operation. Since aerobic microorganisms rely on oxygen to decompose organic matter, a lack of oxygen slows down the decomposition rate, hindering the improvement of composting efficiency. Furthermore, the lack of oxygen during aerobic fermentation leads to the accumulation of gases such as methane and hydrogen sulfide, forming an anaerobic zone that inhibits the fermentation rate. Therefore, it is necessary to develop a bio-organic fertilizer fermentation tank turning device that can continuously aerate the material during the turning process, improving the composting rate and fermentation effect. Utility Model Content

[0003] To address the above technical problems, this utility model provides a biological organic fertilizer fermentation tank turning device that can continuously aerate the material during the turning process, thereby improving the composting rate and fermentation effect, and solving the problem that existing turning machines cannot aerate the material during the turning process.

[0004] To solve the above-mentioned technical problems, the present invention provides a biological organic fertilizer fermentation tank turning device, including a fermentation tank, a movable frame above the fermentation tank, and an installation plate connected below the frame. From front to back, the bottom of the installation plate is provided with a loosening mechanism, a primary turning and aeration mechanism, and a secondary turning and aeration mechanism. The loosening mechanism consists of a row of loosening shovels fixedly connected at intervals to the bottom of the installation plate. Both the primary and secondary turning and aeration mechanisms include a hollow shaft and a fixed shell. Supports are fixedly connected to both sides of the bottom of the installation plate, and rotary joints are fixedly connected to the supports. The hollow shaft is fixedly connected between two corresponding rotary joints. Several fixed shells are fixedly connected at intervals on the hollow shaft. Several turning plates are fixedly connected at intervals on both sides of the fixed shells. Several aeration holes are opened on the turning plates, and the outer edges of the turning plates are inclined outwards. The outer end of the rotary joint is connected to the output end of a blower fixedly connected to the installation plate via an air supply pipe. The hollow shaft is driven to rotate by a turning motor fixedly connected to the installation plate.

[0005] Furthermore, the frame is rotatably connected to both ends of the frame, and movable wheels are fixedly connected to both ends of the rotating shaft. Limiting grooves are opened on the upper edges of both sides of the fermentation tank, and the movable wheels are rolled and locked in the limiting grooves. A drive motor is fixedly connected to the upper end of the frame, and a drive wheel is fixedly connected to the output shaft of the drive motor. A fixed wheel is fixedly connected to the rotating shaft, and the drive wheel and the fixed wheel are connected by a drive chain.

[0006] Furthermore, a telescopic cylinder is fixedly connected to the bottom of the frame, with the output end of the telescopic cylinder facing downwards and fixedly connected to the top of the mounting plate.

[0007] Furthermore, an agent tank is fixedly connected to the frame, and the bottom of the agent tank is connected to the input end of a delivery pump fixedly connected to the mounting plate via a telescopic pipe. A valve is fixedly connected to the telescopic pipe. A spray pipe is fixedly connected to the bottom of the mounting plate between the primary turning and aeration mechanism and the secondary turning and aeration mechanism via a connecting rod. Several spraying discs are fixedly connected at intervals to the lower end of the spray pipe. The output end of the delivery pump is connected to the spray pipe via a pipeline.

[0008] Furthermore, a material-turning motor is fixedly connected to the mounting plate, and a drive wheel is fixedly connected to the output shaft of the material-turning motor. Driven wheels are fixedly connected to both hollow shafts, and the drive wheel is connected to the driven wheel via a transmission chain.

[0009] Furthermore, the loosening shovel and the fixed shell of the primary turning and aeration mechanism are staggered, and the fixed shell of the primary turning and aeration mechanism is staggered with the fixed shell of the secondary turning and aeration mechanism.

[0010] This utility model has the following advantages compared with the prior art:

[0011] 1. This utility model facilitates the overall movement of the device by setting a movable support on the fermentation tank. By setting a loosening shovel at the bottom end of the mounting plate, the raw material pile can be loosened first, making it easier to carry out subsequent turning operations. By setting a primary turning and aeration mechanism and a secondary turning and aeration mechanism, two turning operations can be achieved, improving the turning effect. By using a rotary joint to connect the hollow shaft and the blower, and setting a hollow fixed shell and a turning plate, with aeration holes opened on the turning plate, the material can be aerated during the turning process, thereby improving the fermentation and maturation rate.

[0012] 2. This utility model avoids the problem of material jamming parts during the reverse movement of the device after the device has completed turning in one direction by fixing a telescopic cylinder to the bottom of the frame and connecting the output end of the telescopic cylinder to the top of the mounting plate.

[0013] 3. This utility model sets up a microbial agent tank on the support, sets up a spray pipe between the primary turning and aeration mechanism and the secondary turning and aeration mechanism under the mounting plate, connects a spraying plate to the bottom of the spray pipe, and uses a delivery pump to connect the microbial agent tank and the spray pipe. This allows for the spraying of microbial agents on the material during the turning process, and after spraying, the secondary turning and aeration mechanism performs a secondary turning, ensuring the turning effect while improving the uniformity of mixing between the microbial agents and the material.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-3 The illustrated biological organic fertilizer fermentation tank turning device includes a fermentation tank 1, a movable frame 3 above the fermentation tank 1, and an installation plate 13 connected below the frame 3. The bottom of the installation plate 13 has, from front to back, a loosening mechanism, a primary turning and aeration mechanism, and a secondary turning and aeration mechanism. The loosening mechanism consists of a row of loosening shovels 14 fixedly connected at intervals to the bottom of the installation plate 13. Both the primary and secondary turning and aeration mechanisms include hollow shafts 17 and fixed shells 18. Supports 15 are fixedly connected to both sides of the bottom of the installation plate 13, and rotary joints 16 are fixedly connected to the supports 15. Hollow shafts 17 are fixedly connected between two corresponding rotary joints 16. The hollow shaft 17 is fixedly connected with several hollow internal shells 18 at intervals. Several hollow internal turning plates 19 are fixedly connected to both sides of the fixed shells 18 at intervals. Several aeration holes are opened on the turning plates 19. The hollow shaft 17 is connected to the fixed shells 18, and the fixed shells 18 are connected to the turning plates 19, so that gas can enter the fixed shells 18 from the hollow shaft 17 and be sprayed out from the aeration holes on the turning plates 19. The outer edge of the turning plates 19 is inclined to the outside. The outer end of the rotary joint 16 is connected to the output end of the blower 25 fixedly connected to the mounting plate 13 through the air supply pipe 24. The hollow shaft 17 is driven to rotate by the turning motor 20 fixedly connected to the mounting plate 13.

[0020] It should be noted that in this embodiment, in order to facilitate the turning of the material, the height of the fermentation raw materials placed in the fermentation tank 1 is not higher than the length of the turning plate 19. The length of the turning plate 19 can be set according to the usage requirements. The turning motor 20 is a bidirectional variable frequency motor, which can change the turning direction and adjust the turning speed according to the requirements. The pressure provided by the blower 25 can effectively back-blow and prevent the aeration holes from being blocked by the material.

[0021] To facilitate the movement of the entire device above the fermentation tank 1, the frame 3 is rotatably connected to the shaft 4 at both ends via bearings. The shaft 4 is fixedly connected to the two ends of the shaft 5. Limiting grooves 2 are opened on the upper edge of both sides of the fermentation tank 1. The moving wheels 5 are rolled and locked in the limiting grooves 2. The upper end of the frame 3 is fixedly connected to the drive motor 6 via a motor base and bolts. The output shaft of the drive motor 6 is fixedly connected to the drive wheel 7. The frame 3 is provided with a through hole. The shaft 4 is fixedly connected to the through hole with a fixed wheel 9. The drive wheel 7 and the fixed wheel 9 are connected by a drive chain 8.

[0022] It should be noted that in this embodiment, the drive wheel 7, drive chain 8, and fixed wheel 9 have sufficient transmission wrap angle; the drive motor 6 is a bidirectional variable frequency motor, which can adjust the direction of movement of the device and adjust the speed of movement according to the needs; the drive wheel 7 is a double-layer wheel, which is connected to two fixed wheels 9 by two drive chains 8 respectively, so as to realize the function of driving the four front and rear moving wheels 5 to move synchronously; in order to ensure a better turning effect and avoid the entire device being lifted up during the turning process, causing the moving wheels 5 to turn out of the limiting groove 2, a protective cover is fixedly connected above the limiting groove 2, and one side of the protective cover is fixedly connected to one side of the top of the fermentation tank 1 through a connecting plate, and the moving wheel 5 is rolled between the limiting groove 2 and the protective cover.

[0023] To facilitate the device's reverse return to the starting point and prevent material from getting tangled during the reverse movement, a telescopic cylinder 12 is bolted to the bottom of the frame 3. The output end of the telescopic cylinder 12 faces downwards and is bolted to the top of the mounting plate 13. It should be noted that the telescopic cylinder 12 is either an electric cylinder or an electro-hydraulic cylinder, capable of extending or retracting using electrical control. In this embodiment, to improve the overall stability of the device, an electro-hydraulic cylinder is used for the telescopic cylinder 12.

[0024] To facilitate the simultaneous addition of microbial agents during the turning process and ensure uniform mixing with the fermentation raw materials, an agent tank 10 is fixedly connected to the frame 3. The agent tank 10 has a feeding port at the top, and an end cap is detachably connected to the feeding port. The bottom of the agent tank 10 is connected to the input end of a conveying pump 26, which is bolted to the mounting plate 13, through a telescopic pipe 11 that passes through the frame 3. A valve 29 is fixedly connected to the telescopic pipe 11. A spraying pipe 27 is fixedly connected to the bottom of the mounting plate 13 between the primary turning and aeration mechanism and the secondary turning and aeration mechanism via a connecting rod. Several spraying discs 28 are fixedly connected at intervals at the lower end of the spraying pipe 27. The output end of the conveying pump 26 is connected to the spraying pipe 27 via a pipe.

[0025] To facilitate stable rotation of the primary and secondary turning and aeration mechanisms via the turning motor 20, a drive wheel 21 is fixedly connected to the output shaft of the turning motor 20, and driven wheels 22 are fixedly connected to both hollow shafts 17. The drive wheel 21 is connected to the driven wheels 22 via a transmission chain 23. It should be noted that in this embodiment, the drive wheel 21, driven wheels 22, and transmission chain 23 have sufficient transmission wrap angle; the drive wheel 21 is a double-layered wheel, connected to the two driven wheels 22 of the primary and secondary turning and aeration mechanisms respectively via two transmission chains 23, and driven by a single turning motor 20.

[0026] To ensure better fermentation results, the loosening shovel 14 and the fixed shell 18 of the primary turning and aeration mechanism are staggered, and the fixed shell 18 of the primary turning and aeration mechanism and the fixed shell 18 of the secondary turning and aeration mechanism are staggered.

[0027] The working process of this embodiment is as follows:

[0028] When turning the raw materials for bio-organic fertilizer production, the operator starts the drive motor 6, which drives the drive wheel 7 to rotate. Under the action of the drive chain 8, the fixed wheel 9 rotates, which in turn rotates the rotating shaft 4 and the moving wheel 5, thus moving the entire device above the fermentation tank 1. During the movement, the turning operation is carried out. During the movement, the loosening shovel 14 loosens the material pile to further improve the turning effect. Simultaneously, the operator starts the turning motor 20, which drives the drive wheel 21 to rotate. Under the action of the transmission chain 23, the drive wheels 22 rotate, which in turn drive the two hollow shafts 17 to rotate. When the hollow shafts 17 rotate, they drive the fixed shell 18 and the turning mechanism. The rotating plate 19 turns the material over; simultaneously, the blower 25 starts running, and the blower 25 sends air through the air supply pipe 24, through the rotary joint 16, into the hollow shaft 17, and through the fixed shell 18 and the turning plate 19 to be discharged from the aeration hole, thus performing aeration while turning the pile; microbial agent is added to the agent tank 10, the valve 29 is opened and the conveying pump 26 is started, and the microbial agent enters the spraying pipe 27 through the telescopic pipe 11 and is sprayed onto the raw material from the spraying plate 28; after the primary turning and aeration mechanism turns the pile and sprays the microbial agent, the secondary turning and aeration mechanism turns the material over again, which at the same time enables the microbial agent to be fully mixed with the raw material. After the one-way turning operation in fermentation tank 1 is completed, observe the turning situation. If a second turning is needed, the staff will control the telescopic cylinder 12 to retract, causing the mounting plate 13 to move upward as a whole. Then, the staff will control the drive motor 6 to run in the opposite direction, causing the entire device to move in the opposite direction to the starting point. After controlling the telescopic cylinder 12 to extend so that the loosening shovel 14 contacts the bottom of fermentation tank 1, the staff will control the drive motor 6 to run in the forward direction again, causing the device to move and perform a second turning.
