Description

Technical Field

[0001] This utility model relates to the technical field of composting and fermentation equipment, specifically to an agricultural waste composting and fermentation device. Background Technology

[0002] In the field of agricultural waste treatment, composting is a common and important method. It aims to transform various agricultural wastes into nutrient-rich organic fertilizers, thereby achieving resource recycling and reducing environmental pollution.

[0003] Existing agricultural waste composting and fermentation devices typically employ a fixed stirring structure. Generally, a stirring shaft is installed inside the fermentation tank, with fixed stirring blades connected to it. A motor drives the shaft to rotate, achieving mixing of the waste. This fixed stirring radius design has significant drawbacks. Because the stirring range of the blades is fixed, it is difficult to fully mix the waste in all areas of the fermentation tank, easily creating mixing dead zones. In these dead zones, the waste cannot be effectively turned and mixed, resulting in uneven fermentation and a significantly prolonged fermentation cycle. Moreover, due to insufficient fermentation, the final compost quality is inconsistent, and its fertilizer efficiency is difficult to guarantee, seriously affecting the efficiency and quality of agricultural waste composting and fermentation treatment, and failing to meet the high-efficiency and environmentally friendly production requirements of modern agriculture. Therefore, we propose an agricultural waste composting and fermentation device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an agricultural waste composting and fermentation device, which solves the above-mentioned problems.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an agricultural waste composting and fermentation device, including a fermentation tank and a support leg installed at the bottom of the fermentation tank. The fermentation tank has a feed inlet and a discharge outlet at the bottom. A connecting plate is provided inside the fermentation tank, and a sleeve is fixedly connected to the connecting plate. A drive motor is fixedly installed on the top of the fermentation tank. The output shaft of the drive motor passes through the top of the fermentation tank, extends into the inside of the sleeve, and connects to the connecting plate. Four sets of fixing blocks are installed in a circular array on the upper wall of the connecting plate. Each set of fixing blocks consists of two fixing blocks. A connecting column is fixedly connected between the two fixing blocks. A connecting rod is movably connected to each of the four connecting columns. A stirring blade is fixedly connected to the end of each of the four connecting rods away from the connecting plate. A linkage mechanism that enables the connecting rods to swing is provided inside the fermentation tank.

[0006] Preferably, the linkage mechanism includes a T-shaped groove, a T-shaped slider, a telescopic rod, and a squeezing rod. Each of the four connecting rods has a T-shaped groove on the side wall near the sleeve. A T-shaped slider is movably engaged inside each of the four T-shaped grooves. Four telescopic rods are connected to the outer wall of the sleeve at positions corresponding to the four T-shaped sliders via ball joints. The movable end of each telescopic rod, away from the sleeve, is fixedly connected to the side wall adjacent to the corresponding T-shaped slider via a ball joint. A squeezing rod is fixedly connected to the inner bottom surface of the fermentation tank.

[0007] Preferably, the extrusion rod has an L-shaped structure, and the corner of the extrusion rod is treated with an arc surface. When the T-shaped slider is located at the upper end of the corresponding T-shaped groove, the horizontal height of the point on the connecting rod corresponding to the extrusion rod is the same as the horizontal height of the upper horizontal end of the extrusion rod.

[0008] Preferably, the connecting plate has a connection port at the connection point with the output end of the drive motor, and a fixing bolt is movably engaged inside the connection port. The connecting plate is threadedly connected to the output end of the drive motor through the fixing bolt.

[0009] Preferably, the stirring blade is composed of two symmetrically and vertically arranged W-shaped structures spliced ​​together, and the stirring blade has a through hole formed by the splicing of two vertically arranged W-shaped structures, the diameter of the through hole on the stirring blade gradually decreases towards the clockwise side.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By setting up a linkage mechanism (T-shaped chute, T-shaped slider, telescopic rod, and extrusion rod) and connecting rod in conjunction with the system, a variable stirring radius is achieved to improve stirring efficiency. When the connecting plate rotates, the connecting rod unfolds under the influence of centrifugal force, placing the T-shaped slider at the lower end of the T-shaped chute. When the connecting rod passes the extrusion rod, the arc-shaped surface at the corner of the extrusion rod pushes the connecting rod upward, causing the T-shaped slider to move to the upper end of the T-shaped chute. This changes the position of the stirring blades inside the fermentation tank, and this process is repeated to continuously change the stirring radius. This variable stirring radius design ensures that waste in different locations within the fermentation tank is thoroughly stirred, avoiding the stirring dead zones present in traditional fixed stirring radius equipment. This significantly improves overall stirring efficiency, shortens the fermentation cycle, and enhances fermentation effect and production efficiency.

[0012] 2. By designing specially shaped stirring blades, highly efficient mixing of waste materials is achieved: The stirring blades consist of two symmetrically arranged, vertically aligned W-shaped structures. This structure significantly increases the contact area with the waste materials, allowing for more comprehensive agitation and more uniform mixing. Furthermore, the diameter of the through-holes gradually decreases clockwise. During mixing, according to Bernoulli's principle, the flow rate of waste materials passing through the through-holes increases, further promoting mixing and effectively improving mixing efficiency. This creates favorable conditions for material uniformity in the subsequent fermentation process.

[0013] 3. By setting up a connection port and fixing bolts between the connecting plate and the drive motor, the equipment maintenance and cleaning are facilitated: The threaded connection of the connection port and fixing bolts allows operators to easily disassemble the connecting plate during equipment use. This enables timely cleaning of the connecting plate and its related components, removing residual waste, and also facilitates the troubleshooting and repair of potential malfunctions. This effectively ensures stable equipment operation, reduces equipment damage caused by component failures or the accumulation of residual materials, thereby extending the equipment's service life and lowering overall maintenance and operating costs.

[0014] 4. By designing an arc-shaped surface at the corner of the extrusion rod, frictional resistance is reduced, ensuring smooth operation of the equipment. The arc-shaped surface design at the corner of the extrusion rod effectively reduces the frictional resistance when the connecting rod contacts the extrusion rod. During equipment operation, the connecting rod frequently interacts with the extrusion rod to change the mixing radius. Lower frictional resistance ensures the smoothness of the connecting rod as it passes the extrusion rod, reducing wear between components. This not only reduces the equipment failure rate and downtime and maintenance costs due to component replacement, but also ensures that the equipment can operate stably and efficiently for extended periods, improving the overall reliability and durability of the equipment.

[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0024] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 7 The present invention will be further described below.

[0025] An agricultural waste composting and fermentation device includes a fermentation tank 1 and four support legs 2 installed at the bottom of the fermentation tank 1. These four support legs provide stable support for the fermentation tank 1. The fermentation tank 1 has a feed inlet 3 with a sealing plug for sealing it. The bottom of the fermentation tank 1 has a discharge outlet 5 with a valve for closing it. A connecting plate 6 is installed inside the fermentation tank 1, and a sleeve 7 is fixedly connected to the connecting plate 6. A drive motor 4 is fixedly installed on the top of the fermentation tank 1, and the output shaft of the drive motor 4 extends through the top of the fermentation tank 1 and into the sleeve 7. The connecting plate 6 is connected to the drive motor 4, which can drive the connecting plate 6 to rotate clockwise inside the fermentation tank 1. The upper wall of the connecting plate 6 is equipped with four sets of fixing blocks 9 in a ring array. Each set of fixing blocks 9 consists of two fixing blocks 9. A connecting column 17 is fixedly connected between the two fixing blocks 9. A connecting rod 10 is movably connected to each of the four connecting columns 17. The four connecting rods 10 are arranged in a ring array inside the fermentation tank 1. A stirring blade 11 is fixedly connected to the end of each of the four connecting rods 10 away from the connecting plate 6. The stirring blade 11 on the connecting rod 10 can stir and mix the waste inside the fermentation tank 1. The fermentation tank 1 is equipped with a linkage mechanism that can make the connecting rods 10 swing.

[0026] During use, the waste to be mixed can be put into the fermentation tank 1 through the feed port 3, and discharged from the fermentation tank 1 through the discharge port 5. After the waste is put into the fermentation tank 1, the drive motor 4 is started to drive the connecting plate 6 to rotate clockwise inside the fermentation tank 1. At this time, the four connecting rods 10 rotate together with the connecting plate 6. The connecting rods 10 drive the stirring blades 11 to complete the mixing of the waste inside the fermentation tank 1. At the same time, in conjunction with the linkage mechanism inside the fermentation tank 1, the four connecting rods 10 can be driven to swing inside the fermentation tank 1, thereby changing the stirring radius of the equipment and greatly improving the stirring efficiency of the equipment, so that the waste inside the fermentation tank 1 can be fully mixed.

[0027] The linkage mechanism includes a T-shaped groove 12, a T-shaped slider 13, a telescopic rod 14, and a pressing rod 15. Each of the four connecting rods 10 has a T-shaped groove 12 on one side wall near the sleeve 7. A T-shaped slider 13 is movably engaged inside each of the four T-shaped grooves 12. The T-shaped slider 13 can slide inside the T-shaped groove 12, and the T-shaped structure greatly improves the stability of the T-shaped slider 13 during movement. Furthermore, the T-shaped slider has inclined surfaces on both sides, allowing it to scrape away accumulated waste inside the T-shaped groove 12 as it moves, preventing waste from accumulating inside the T-shaped groove 12 and affecting its movement. The T-shaped slider 13 has a rectangular shape... Figure 7 As shown, four telescopic rods 14 are connected to the outer wall of the sleeve 7 at the positions corresponding to the four T-shaped sliders 13 via ball joints. The movable end of the telescopic rod 14 away from the sleeve 7 is fixedly connected to the side wall adjacent to the corresponding T-shaped slider 13 via a ball joint. Since the telescopic rod 14 is connected to the sleeve 7 via a ball joint, and the output end of the telescopic rod 14 is connected to the T-shaped slider 13 via a ball joint, the telescopic rod 14 can maintain normal connection with the T-shaped slider 13 when the T-shaped slider 13 moves inside the T-shaped groove 12. A squeezing rod 15 is fixedly connected to the bottom surface of the fermentation tank 1.

[0028] The extrusion rod 15 has an L-shaped structure, and the corners of the extrusion rod 15 are treated with arc surfaces. When the T-shaped slider 13 is located at the upper end of the corresponding T-shaped groove 12, the horizontal height of the point on the connecting rod 10 corresponding to the extrusion rod 15 is the same as the horizontal height of the upper horizontal end of the extrusion rod 15. Figure 2 As shown.

[0029] During use, the four connecting rods 10 are affected by centrifugal force as the connecting plate 6 rotates, causing them to unfold away from the connecting plate 6. This results in the T-shaped slider 13 always being positioned at the lower end of the T-shaped groove 12. Consequently, the horizontal height of the connecting rod 10 corresponding to the extrusion rod 15 is lower than the horizontal height of the extrusion rod 15. When the connecting rod 10 passes the extrusion rod 15, it will contact the arc-shaped surface at the corner of the extrusion rod 15. The arc-shaped surface of the extrusion rod 15 will push the connecting rod 10 upward, causing the T-shaped slider 13 to move to the upper end of the T-shaped groove 12. As the position of the T-shaped slider 13 changes within the T-shaped groove 12, the position of the stirring blade 11 within the fermentation tank 1 also changes. By repeatedly pressing the extrusion rod 15, the four connecting rods 10 can be squeezed to swing up and down continuously, causing the position of the stirring blade 11 on the connecting rods 10 to change continuously. This achieves the effect of changing the stirring radius of the equipment, thereby improving the stirring efficiency.

[0030] By setting the corner of the extrusion rod 15 to an arc surface, the frictional resistance when the connecting rod 10 contacts the extrusion rod 15 can be greatly reduced, ensuring the smooth passage of the connecting rod 10 through the extrusion rod 15, thereby ensuring the normal operation of the equipment.

[0031] A connection port 16 is provided on the connection plate 6 at the connection point with the output end of the drive motor 4. A fixing bolt 8 is movably engaged inside the connection port 16, and the connection plate 6 is threadedly connected to the output end of the drive motor 4 through the fixing bolt 8.

[0032] Since the drive motor 4 is threadedly connected to the connecting plate 6 via the fixing bolt 8, it is convenient for staff to disassemble the connecting plate 6 during use for cleaning and maintenance, thereby improving the service life of the equipment.

[0033] The stirring blade 11 is composed of two symmetrically and vertically arranged W-shaped structures joined together, and the stirring blade 11 also has a through hole formed by two vertically arranged W-shaped structures joined together. The diameter of the through hole on the stirring blade 11 gradually decreases towards the clockwise side, such as... Figure 5 As shown.

[0034] Since the stirring blade 11 is composed of two symmetrically and vertically arranged W-shaped structures spliced ​​together, it can greatly increase the contact area between the stirring blade 11 and the waste, thereby improving the mixing efficiency. In addition, the internal diameter of the through hole formed by the two vertically arranged W-shaped structures on the stirring blade 11 gradually decreases in the clockwise direction, which can accelerate the flow rate of the waste passing through the through hole under the action of Bernoulli's principle, thereby further improving the mixing efficiency.

[0035] Working principle:

[0036] During use, the waste to be mixed can be put into the fermentation tank 1 through the feed port 3, and discharged from the fermentation tank 1 through the discharge port 5. After the waste is put into the fermentation tank 1, the drive motor 4 is started to drive the connecting plate 6 to rotate clockwise inside the fermentation tank 1. At this time, the four connecting rods 10 rotate together with the connecting plate 6. The connecting rods 10 drive the stirring blades 11 to complete the mixing of the waste inside the fermentation tank 1. At the same time, in conjunction with the linkage mechanism inside the fermentation tank 1, the four connecting rods 10 can be driven to swing inside the fermentation tank 1, thereby changing the stirring radius of the equipment and greatly improving the stirring efficiency of the equipment, so that the waste inside the fermentation tank 1 can be fully mixed.

[0037] During use, the four connecting rods 10 are affected by centrifugal force as the connecting plate 6 rotates, causing them to unfold away from the connecting plate 6. This results in the T-shaped slider 13 always being positioned at the lower end of the T-shaped groove 12. Consequently, the horizontal height of the connecting rod 10 corresponding to the extrusion rod 15 is lower than the horizontal height of the extrusion rod 15. When the connecting rod 10 passes the extrusion rod 15, it will contact the arc-shaped surface at the corner of the extrusion rod 15. The arc-shaped surface of the extrusion rod 15 will push the connecting rod 10 upward, causing the T-shaped slider 13 to move to the upper end of the T-shaped groove 12. As the position of the T-shaped slider 13 changes within the T-shaped groove 12, the position of the stirring blade 11 within the fermentation tank 1 also changes. By repeatedly pressing the extrusion rod 15, the four connecting rods 10 can be squeezed to swing up and down continuously, causing the position of the stirring blade 11 on the connecting rods 10 to change continuously. This achieves the effect of changing the stirring radius of the equipment, thereby improving the stirring efficiency.

[0038] Since the stirring blade 11 is composed of two symmetrically and vertically arranged W-shaped structures spliced ​​together, it can greatly increase the contact area between the stirring blade 11 and the waste, thereby improving the mixing efficiency. In addition, the internal diameter of the through hole formed by the two vertically arranged W-shaped structures on the stirring blade 11 gradually decreases in the clockwise direction, which can accelerate the flow rate of the waste passing through the through hole under the action of Bernoulli's principle, thereby further improving the mixing efficiency.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
