Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering, and in particular to a straw-based bio-fertilizer maturation and fermentation device. Background Technology

[0002] The straw-based bio-fertilizer fermentation device is an innovative piece of equipment for the resource utilization of agricultural waste straw. This device integrates microbial fermentation technology to rapidly ferment organic waste such as straw under specific conditions. Under suitable temperature, humidity, aeration, and the action of catalysts, the recalcitrant components in the straw, such as cellulose and hemicellulose, are effectively decomposed and transformed into bio-fertilizer rich in nitrogen, phosphorus, potassium, and various trace elements. This process not only achieves the harmless treatment and reduction of straw but also promotes soil fertility improvement, providing a green and efficient solution for sustainable agricultural development.

[0003] However, in the existing technology, during the use of fermentation equipment, a large amount of fertilizer will gradually adhere to its inner wall. As time goes by, this fertilizer will continue to accumulate, which will not only reduce the effective volume of the fermentation tank, but also have an adverse effect on the fermentation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a straw-based bio-fertilizer maturation and fermentation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a straw-based bio-fertilizer maturation and fermentation device, comprising a tank, a cover plate at the upper end of the tank, a support block fixedly connected to the upper end of the cover plate, a dual-shaft motor at the upper end of the support block, a stirring rod at one end of the dual-shaft motor, a lead screw at the other end of the dual-shaft motor, a guide rod fixedly connected to the upper end of the cover plate near the support block, a movable plate slidably connected to the outside of the guide rod, a threaded hole penetrating through the middle of the movable plate, a sliding rod fixedly connected to the lower edge of the movable plate, and a scraper ring fixedly connected to the other end of the sliding rod.

[0006] Preferably, a discharge pipe is fixedly connected to the lower end of the tank, and a control valve is installed inside the discharge pipe. A feeding pipe is fixedly connected to the right side of the tank, and a feeding pipe is fixedly connected to the other side of the tank. A screen box is fixedly connected to the upper end of the feeding pipe.

[0007] Preferably, the screen box is provided with a screen mesh inside, the screen mesh has a limiting hole inside, a fixing block is fixedly connected to the upper end of the screen box, a slider is provided inside the fixing block, a telescopic rod is provided at the upper edge of the slider, a spring is sleeved on the outside of the telescopic rod, a pull rod is fixedly connected to the middle of the upper end of the slider, and a locking rod is fixedly connected to the lower end of the slider.

[0008] Preferably, the internal thread of the movable plate is adapted to the external thread of the lead screw.

[0009] Preferably, the telescopic rods are in two sets and are symmetrically arranged about the centerline of the fixed block.

[0010] Preferably, the slider slides inside the fixed block via a pull rod, a telescopic rod, and a spring.

[0011] Using the above technical solution, by turning on the dual-shaft motor, the upper lead screw starts to rotate. Under the action of its external thread, the moving plate moves the sliding rod downward, and the scraper ring moves closely against the inner wall of the tank. With the continuous operation of the dual-shaft motor, the scraper ring can achieve a cyclic lifting and lowering action within the tank, thereby scraping off the fertilizer adhering to the inner wall of the tank. At the same time, the setting of two sets of guide rods can enhance the stability of the moving plate driving the scraper ring to lift and lower, ensuring that the whole process is smooth and reliable. In addition, the other end of the dual-shaft motor can drive the stirring rod to stir the fertilizer in the tank, so that the fertilizer is fully mixed and effectively improves the fermentation effect. The position of the scraper ring can be adjusted by components such as the dual-shaft motor, lead screw, moving plate, and sliding rod, thereby achieving the cleaning of fertilizer adhering to the inner wall of the tank, ensuring that the tank always maintains sufficient effective volume, and also improving the fermentation efficiency.

[0012] Using the above technical solution, pulling the lever causes the slider to move. During the slider's movement, the telescopic rod and spring are compressed, causing the locking rod to disengage from the limiting hole, thus releasing the screen's restriction. At this point, simply pulling the screen laterally allows for disassembly. Similarly, during installation, the screen is slid into the screen box. When it reaches the preset position, the spring rebounds and pushes the slider in the opposite direction, causing the locking rod to re-enter the limiting hole, thus restricting the screen's movement and completing the installation. The components, including the fixing block, locking rod, telescopic rod, and spring, allow for quick installation and removal of the screen, facilitating maintenance during long-term use. Furthermore, the screen effectively filters the added catalysts, preventing clumps of catalyst from falling into the tank and ensuring a more complete and efficient fermentation reaction.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1

[0021] Please see Figures 1-5 This utility model provides a technical solution: a straw-based bio-fertilizer maturation and fermentation device, including a tank body 1, a cover plate 2 at the upper end of the tank body 1, a support block 3 fixedly connected to the upper end of the cover plate 2, a dual-shaft motor 4 at the upper end of the support block 3, a stirring rod 5 at one end of the dual-shaft motor 4, a lead screw 6 at the other end of the dual-shaft motor 4, a guide rod 7 fixedly connected to the upper end of the cover plate 2 near the support block 3, a movable plate 8 slidably connected to the outside of the guide rod 7, a threaded hole 9 penetrating through the middle of the movable plate 8, a sliding rod 10 fixedly connected to the lower edge of the movable plate 8, a scraper ring 11 fixedly connected to the other end of the sliding rod 10, and the internal thread of the movable plate 8 being compatible with the external thread of the lead screw 6.

[0022] Specifically, when the dual-axis motor 4 is turned on, it drives the upper lead screw 6 to rotate. Under the action of its external thread, the moving plate 8 moves the slide bar 10 downward, and the scraper ring 11 moves closely against the inner wall of the tank 1. With the continuous operation of the dual-axis motor 4, the scraper ring 11 can perform a cyclic lifting and lowering action within the tank 1, thereby scraping off the fertilizer adhering to the inner wall of the tank 1. At the same time, the setting of two sets of guide rods 7 can enhance the stability of the moving plate 8 driving the scraper ring 11 to lift and lower, ensuring that the whole process is smooth and reliable. In addition, the other end of the dual-axis motor 4 can drive the stirring rod 5 to stir the fertilizer in the tank 1, so that the fertilizer is fully mixed and the fermentation effect is effectively improved. Through the components such as the dual-axis motor 4, lead screw 6, moving plate 8, and slide bar 10, the position of the scraper ring 11 can be adjusted, thereby cleaning the fertilizer adhering to the inner wall of the tank 1, ensuring that the inside of the tank 1 always maintains sufficient effective volume, and also improving the fermentation efficiency.

[0023] Example 2

[0024] Please see Figures 1-5 This utility model provides a technical solution: a straw-based bio-fertilizer maturation and fermentation device. A discharge pipe 12 is fixedly connected to the lower end of a tank 1, and a control valve 13 is installed inside the discharge pipe 12. A feeding pipe 14 is fixedly connected to the right side of the tank 1, and a feeding pipe 15 is fixedly connected to the other side of the tank 1. A sieve box 16 is fixedly connected to the upper end of the feeding pipe 15, and a screen 17 is installed inside the sieve box 16. Limiting holes 18 are formed inside the screen 17. The upper end of the sieve box 16 is fixed... A fixed block 19 is connected, and a slider 20 is set inside the fixed block 19. A telescopic rod 22 is set at the upper edge of the slider 20. A spring 23 is sleeved on the outside of the telescopic rod 22. A pull rod 21 is fixedly connected to the middle of the upper end of the slider 20. A locking rod 24 is fixedly connected to the lower end of the slider 20. There are two sets of telescopic rods 22, which are symmetrically arranged about the center line of the fixed block 19. The slider 20 slides inside the fixed block 19 through the pull rod 21 in cooperation with the telescopic rod 22 and the spring 23.

[0025] Specifically, pulling the lever 21 causes the slider 20 to move. During the movement of the slider 20, the telescopic rod 22 and spring 23 are compressed, and the locking rod 24 disengages from the limiting hole 18, thereby releasing the restriction on the screen 17. At this time, the screen 17 can be disassembled simply by pulling it sideways. Similarly, during installation, the screen 17 is slid into the screen box 16. When it reaches the preset position, the spring 23 rebounds and pushes the slider 20 to move in the opposite direction. The locking rod 24 re-enters the limiting hole 18, thus limiting the screen 17 and completing its installation. The screen 17 can be quickly installed and removed using components such as the fixing block 19, locking rod 24, telescopic rod 22, and spring 23, which allows for maintenance during long-term use. At the same time, the screen 17 can effectively filter the catalyst added to the reaction, preventing the catalyst from condensing into clumps and falling into the tank 1, and ensuring that the fermentation reaction proceeds more fully and efficiently.

[0026] Working principle: When using this fermentation device, firstly, the crushed straw is transported into the tank 1 via the feeding pipe 14. Then, the catalyst is poured into the sieve box 16. The catalyst enters the tank 1 through the feeding pipe 15 to catalyze the straw. During this process, if the catalyst clumps together, it will be intercepted and filtered by the sieve 17 to prevent it from falling into the tank 1. When it is necessary to scrape off the fertilizer adhering to the inner wall of the tank 1, the dual-shaft motor 4 is turned on. The dual-shaft motor 4 drives the upper lead screw 6 to rotate. Under the action of its external thread, the moving plate 8 will drive the sliding rod 10 to move towards... The scraper ring 11 moves downwards and then moves closely against the inner wall of the tank 1. Under the continuous operation of the dual-shaft motor 4, the scraper ring 11 can achieve a cyclic lifting and lowering action within the tank 1, thereby scraping off the fertilizer adhering to the inner wall of the tank 1. At the same time, the setting of two sets of guide rods 7 can enhance the stability of the scraper ring 11 when the moving plate 8 drives it to lift and lower, ensuring that the whole process is smooth and reliable. In addition, the other end of the dual-shaft motor 4 can drive the stirring rod 5 to stir the fertilizer in the tank 1, so that the fertilizer is fully mixed and effectively improves the fermentation effect. Through the dual-shaft motor 4, lead screw 6, moving plate 8, slide rod 10 and other components, the scraper ring 11 can be moved downwards and downwards. The position of ring 11 can be adjusted to clean the fertilizer adhering to the inner wall of tank 1, ensuring that the inside of tank 1 always maintains sufficient effective volume and improving fermentation efficiency. When maintenance of screen 17 is required, pull rod 21, which will drive slider 20 to move. During the movement of slider 20, telescopic rod 22 and spring 23 will be compressed, and locking rod 24 will disengage from limiting hole 18, thereby releasing the limiting of screen 17. At this time, screen 17 can be disassembled by simply pulling it sideways. Similarly, during installation, screen 17 is moved along... The screen box 16 slides in, and when it reaches the preset position, the spring 23 rebounds and pushes the slider 20 to move in the opposite direction. The locking rod 24 re-enters the limiting hole 18 to limit the screen 17, thus completing its installation. The screen 17 can be quickly installed and removed through components such as the fixing block 19, locking rod 24, telescopic rod 22, and spring 23, which allows for maintenance during long-term use. At the same time, the screen 17 can effectively filter the catalyst added to the reaction, preventing the catalyst from condensing into clumps and falling into the tank 1, and also ensuring that the fermentation reaction is more complete and efficient.
