Description

Technical Field

[0001] This invention relates to the field of soil turning and turning technology, and in particular to a soil turning and turning device for the production of bio-fertilizer. Background Technology

[0002] The fermentation of bio-fertilizers relies on the metabolic activity of aerobic microorganisms such as Bacillus and Actinomycetes. These microorganisms can efficiently decompose large organic molecules such as cellulose and lignin when oxygen is sufficient, transforming them into humus and readily available nutrients. The turning device can increase the oxygen permeability by 40%-60% by turning the material regularly, avoiding the growth of pathogens caused by local anaerobic environments, while promoting the reproduction of functional bacteria.

[0003] In existing bio-fertilizer production, soil turning devices generally suffer from problems such as insufficient turning uniformity, material accumulation at the edges, and redundant power systems. Specifically, existing trough-type turning machines rely on a single turning wheel structure with a fixed turning radius, making it difficult to effectively turn the material at the edge of the fermentation pile, resulting in dead zones in the turning process. This can easily lead to localized anaerobic fermentation. At the same time, some equipment requires separate motors to drive the turning and material pushing mechanisms, which not only increases energy consumption but also increases the failure rate due to poor coordination among multiple power sources. In addition, the angle of the shovel components in existing turning devices is mostly fixed, making it difficult to dynamically adjust according to the material accumulation state. This can easily cause sticking and clogging of high-moisture or long-fiber materials, requiring frequent shutdowns for cleaning, which in turn affects continuous production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of insufficient uniformity of turning and composing, accumulation of material at the edges, and redundancy of the power system. To this end, we propose a soil turning and composing device for the production of bio-fertilizer.

[0005] The main technical solution is as follows: a soil turning and tamping device for the production of bio-fertilizer, including a turning and tamping vehicle body, a motor fixedly installed on one side surface of the turning and tamping vehicle body, a turning and tamping wheel and a bidirectional threaded rod respectively limited and installed between the inner walls of the two sides of the turning and tamping vehicle body, the bidirectional threaded rod being located above the turning and tamping wheel, and the outer surfaces of the two sides of the bidirectional threaded rod having threaded surfaces in opposite directions, and the output end of the motor being fixedly connected to one end of the transmission end of the turning and tamping wheel;

[0006] A transmission mechanism is connected between the motor and the bidirectional threaded rod to enable the turning wheel and the bidirectional threaded rod to rotate synchronously.

[0007] The overturning mechanism is connected to the threaded surfaces on both sides of the bidirectional threaded rod by two sets of symmetrical threads, so that the overturning mechanism can move laterally in a relative manner along the axial direction. By moving laterally relative to the outside of the overturning wheel, the soil accumulated at the edge and center of the overturning wheel is pushed to the central overturning area and the edge overturning area.

[0008] An angle-rotating mechanism is hinged to the overturning mechanism so that the angle-rotating mechanism rotates around the hinge axis. When the overturning mechanism moves inward relative to the shovel, the horizontal angle of the overturning mechanism decreases, and the accumulated soil at the edge gathers towards the central overturning area. When the overturning mechanism moves outward relative to the shovel, the horizontal angle of the overturning mechanism increases, and the accumulated soil at the center peels away and disperses towards the edge overturning area.

[0009] Preferably, several sets of L-shaped turning rods are fixedly installed around the outer surface of the turning wheel in a circular pattern.

[0010] Preferably, the transmission mechanism includes:

[0011] A first gear sleeve and a second gear sleeve are provided. The first gear sleeve is fixedly sleeved on the outside of the output shaft of the motor near the turning wheel, and the second gear sleeve is fixedly sleeved on the outside of one end of the transmission end of the bidirectional threaded rod. The radius of the first gear sleeve is larger than the radius of the second gear sleeve.

[0012] The teeth of the first gear sleeve and the second gear sleeve are meshed together to form a rack chain. The output shaft of the motor and the outer side of the transmission end of one end of the bidirectional threaded rod are both fixedly fitted with limit sleeves. The limit sleeves abut against the other side surface of the rack chain away from the first gear sleeve and the second gear sleeve.

[0013] Preferably, the overturning mechanism includes:

[0014] The displacement sleeve is arranged in two symmetrical sets and threaded onto the threaded surfaces on both sides of the bidirectional threaded rod. Each set of the displacement sleeve has a vertical fixing rod fixedly connected to the lower surface on both sides. The lower surface of the vertical fixing rod is provided with a groove. A fixing shaft is fixedly inserted between the outer surfaces on both sides of the vertical fixing rod located at the groove position. An L-shaped shovel and overturning rod is sleeved on the outer surface of the fixing shaft. Shovel inserts are evenly installed on both sides of one end of the L-shaped shovel and overturning rod.

[0015] Preferably, the angle rotation mechanism includes:

[0016] A fixed frame rod is provided, the upper end of which is fixedly installed on the inner top wall of the center of the dumping vehicle body, and a central fixing sleeve is fixedly connected to the lower end surface of the fixed frame rod. The smooth dividing surface of the threaded surfaces on both sides of the bidirectional threaded rod is rotatably sleeved inside the central fixing sleeve.

[0017] The outer surfaces of the two sides of the central fixing sleeve are symmetrically hinged with a first hinge rod, and the other end of the first hinge rod away from the central fixing sleeve is hinged with a second hinge rod, which is hinged to one side of the outer surface of the L-shaped overturning rod.

[0018] Preferably, an operating room is fixedly installed on the upper surface of the dumping vehicle.

[0019] Preferably, a ladder is fixedly installed on the side surface of the dumping vehicle body near the motor, and an equipment through slot is opened on the side surface of the dumping vehicle body near the ladder, with the rack and pinion chain drive inside the equipment through slot;

[0020] A baffle is fixedly connected to one end of the ladder near the equipment channel.

[0021] Preferably, four sliding grooves are evenly provided on the top wall of the turning vehicle body, and sliding rods are slidably connected inside each sliding groove. The lower ends of the sliding rods are respectively fixedly connected to the upper surfaces of the two sets of displacement sleeves on both sides.

[0022] The technical effects and advantages of this invention are as follows:

[0023] In this invention, a symmetrical shovel mechanism is driven by a bidirectional threaded rod, thereby achieving lateral sweeping within the movement range of both sides of the turning wheel. In conjunction with the angle rotation mechanism, when moving inward, the soil accumulated at the edge is gathered towards the center, and when moving outward, the material in the center is peeled away from the edge. This effectively eliminates some of the dead corners in the turning process that exist in existing devices, improves the uniformity of material mixing, and shortens the fermentation cycle.

[0024] In this invention, a transmission mechanism consisting of a motor, gears, and a rack and pinion chain is used to enable the turning wheel and the bidirectional threaded rod to rotate synchronously at a 1:1 speed ratio. This eliminates the need for an independent drive component, effectively reducing overall energy consumption. At the same time, the lateral constraint of the limit sleeve on the rack and pinion chain prevents transmission slippage, thus reducing the failure rate of the equipment during continuous operation.

[0025] In this invention, the L-shaped shovel lever is hinged to the vertical fixed rod via a fixed shaft. In conjunction with the hinged movement of the first hinge rod and the second hinge rod, the angle of material shoveling and fusion can be automatically adjusted according to the material resistance, thereby reducing the entanglement rate of long fiber materials such as straw and significantly shortening the cleaning time for sticky and clogged high-moisture materials.

[0026] In this invention, the sliding guide structure of four symmetrically distributed grooves and slide rods improves the lateral movement accuracy of the displacement sleeve, thereby effectively ensuring that the overturning mechanism can operate flexibly in the narrow fermentation tank. In addition, the central fixed sleeve provides central support for the bidirectional threaded rod, reducing the amplitude of annoying vibrations during equipment operation and thus extending its service life.

[0027] In this invention, the overturning and angle adjustment actions are automatically completed through mechanical linkage, eliminating the need for manual parameter setting, thereby greatly reducing the rate of misjudgment and error in operation. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0038] Example 1: Refer to Figures 1 to 8 As shown, the present invention provides a technical solution: a soil turning and turning device for the production of bio-fertilizer, including a turning and turning vehicle body 1, a motor 5 fixedly installed on one side surface of the turning and turning vehicle body 1, an operating chamber 2 fixedly installed on the upper surface of the turning and turning vehicle body 1, a turning wheel 6 and a bidirectional threaded rod 9 respectively limited and installed between the inner walls of the two sides of the turning and turning vehicle body 1, a number of L-shaped turning rods 7 are fixedly installed in a circular pattern on the outer surface of the turning wheel 6, the bidirectional threaded rod 9 is located above the turning wheel 6, and the outer surfaces of the two sides of the bidirectional threaded rod 9 are provided with threaded surfaces in opposite directions, and the output end of the motor 5 is fixedly connected to one end of the transmission end of the turning wheel 6;

[0039] A transmission mechanism is connected between the motor 5 and the bidirectional threaded rod 9, and the turning wheel 6 and the bidirectional threaded rod 9 rotate synchronously.

[0040] The overturning mechanism consists of two sets of symmetrical threaded connections on the threaded surfaces of the two-way threaded rod 9. The overturning mechanism moves laterally in a relative manner along the axial direction. By moving laterally on the outside of the overturning wheel 6, the overturning wheel 6 pushes the accumulated soil at the edge and center to the center overturning area and the edge overturning area.

[0041] An angular rotation mechanism is hinged to the overturning mechanism. The angular rotation mechanism rotates around the hinge axis. When the overturning mechanism moves inward relative to the angular rotation mechanism, the horizontal angle of the overturning mechanism decreases, and the accumulated soil at the edge gathers towards the central overturning area. When the overturning mechanism moves outward relative to the angular rotation mechanism, the horizontal angle of the overturning mechanism increases, and the accumulated soil at the center peels off and disperses towards the edge overturning area.

[0042] The overall structural operation flow of this embodiment is as follows:

[0043] Equipment positioning and start-up preparation: Drive the turning vehicle 1 to the top of the bio-fertilizer fermentation tank, set the turning parameters, including rotation speed and lateral movement frequency, through the control system in the control room 2, start the motor 5 in the control room 2, the output shaft of the motor 5 drives the turning wheel 6 to rotate, and the L-shaped turning rod 7 on the outer circumference is driven to rotate by the turning wheel 6 while inserting into the material layer of depth. Through the "L-shaped" structure, the bottom anaerobic material is turned upward and the surface aerobic material is pressed down, forming a vertical material exchange.

[0044] Synchronous transmission triggering and lateral force transmission: The output shaft of motor 5 will also drive the transmission mechanism at the same time, thereby driving the bidirectional threaded rod 9 to rotate at the same speed as the turning wheel 6 with a speed ratio of 1:1, realizing real-time coordination between the rotation and turning of the turning wheel 6 and the lateral pushing of the shovel mechanism;

[0045] Dynamic material distribution and turning zone coverage: During the inward gathering stage, the turning mechanism moves from both sides of the fermentation tank towards the center. The angle rotation mechanism drives the turning mechanism to reduce the horizontal angle, and the turning mechanism pushes the accumulated soil at the edge to the central turning zone directly below the turning wheel 6.

[0046] During the outward peeling stage, the shovel mechanism moves from the center to both sides, and the angle rotation mechanism drives the shovel mechanism to increase the horizontal angle. The shovel mechanism peels the loose material in the central shovel area to the edge, thus forming a "center-edge-center" cyclic shovel path that covers the entire cross section of the fermentation tank.

[0047] With the combined use of the transmission mechanism, shovel mechanism and angle rotation structure of this soil turning and turning device, the composite action of rotational turning and lateral pushing improves the uniformity of material mixing, avoids the growth of pathogens caused by local anaerobic conditions, and promotes increased oxygen permeability, enhanced aerobic microbial activity, increased cellulose decomposition rate and shortened fermentation cycle. In addition, the single motor drives the dual mechanisms, which can significantly reduce energy consumption and daily costs.

[0048] Reference Figures 1 to 8 As shown, in this embodiment, the transmission mechanism includes:

[0049] The first gear sleeve 10 and the second gear sleeve 11 are fixedly sleeved on the outside of the output shaft of the motor 5 near the turning wheel 6, and the second gear sleeve 11 is fixedly sleeved on the outside of the transmission end of one end of the bidirectional threaded rod 9, and the radius of the first gear sleeve 10 is larger than the radius of the second gear sleeve 11.

[0050] The teeth of the first gear sleeve 10 and the second gear sleeve 11 mesh together to connect the rack chain 12. The output shaft of the motor 5 and the external of the transmission end of one end of the bidirectional threaded rod 9 are both fixedly sleeved with a limiting sleeve 13. The limiting sleeve 13 abuts against the other side surface of the rack chain 12 away from the first gear sleeve 10 and the second gear sleeve 11.

[0051] In this embodiment, the operation procedure of the transmission mechanism is as follows:

[0052] While the output shaft of motor 5 drives the turning wheel 6 to rotate, it also drives the first gear sleeve 10, which is fixedly sleeved outside the output shaft of motor 5, to rotate synchronously. Since the teeth of the first gear sleeve 10 and the second gear sleeve 11 are meshed with the rack chain 12, and the radius of the first gear sleeve 10 is larger than the radius of the second gear sleeve 11, while the teeth of the first gear sleeve 10 drive the rack chain 12 to mesh and transmit power, the rack chain 12 synchronously drives the second gear sleeve 11 to mesh and transmit power synchronously. Then, the second gear sleeve 11 drives the bidirectional threaded rod 9 to perform limited threaded rotation between the inner walls of the turning vehicle body 1. Thus, the gear-rack chain meshing transmission efficiency of the transmission mechanism can reduce power loss compared with the belt transmission efficiency, and greatly improve the utilization rate of the actual output power of motor 5.

[0053] Furthermore, it is worth noting that the limiting sleeve 13 is fixed to the motor shaft and the end of the bidirectional threaded rod 9 by a key connection, and its inner surface forms a lateral constraint with the outer surface of the rack chain 12, preventing the rack chain 12 from skipping teeth or derailing when it is running at high speed.

[0054] Reference Figures 1 to 7 As shown in this implementation plan, the overturning mechanism includes:

[0055] The displacement sleeve 14 is arranged in two symmetrical sets and threaded onto the threaded surfaces on both sides of the bidirectional threaded rod 9. Each set of displacement sleeve 14 has a vertical fixing rod 17 fixedly connected to the lower surface on both sides. The lower surface of the vertical fixing rod 17 is provided with a groove 18. A fixing shaft 24 is fixedly inserted between the outer surfaces on both sides of the vertical fixing rod 17 located in the groove 18. An L-shaped shovel and overturning rod 19 is sleeved on the outer surface of the fixing shaft 24. Shovel inserts 20 are evenly installed on both sides of one end of the L-shaped shovel and overturning rod 19.

[0056] In this embodiment, the operation procedure of the overturning mechanism is as follows:

[0057] When the bidirectional threaded rod 9 is driven by the output shaft of the motor 5, the displacement sleeve 14 moves axially through the bidirectional threaded rod 9 with matching internal and external threads. The displacement sleeve 14 drives the vertical fixed rod 17 to move axially. Subsequently, the vertical fixed rod 17 drives the lower L-shaped shovel 19 to sweep within the material layer. Finally, the L-shaped shovel 19 drives the shovel insert 20 to move axially laterally. When the L-shaped shovel 19 moves laterally, it inserts material. The insertion resistance is reduced by the "pointed teeth + inclined surface" structure. When the shovel mechanism moves inward, the contact area between the shovel insert 20 and the material increases, pushing the accumulated material at the edge to the central turning area to ensure improved integration with air and material during the turning process.

[0058] In the soil turning and turning mechanism of this device, it is worth noting that the staggered tooth design of the shovel insert 20 significantly reduces the length entanglement rate of straw materials, thereby reducing downtime for cleaning. In addition, through the upper thread design of the bidirectional threaded rod 9, the lateral movement speed of the turning mechanism is matched with the pushing force, which can maintain stable pushing even under the high viscosity of sticky and wet materials without slippage.

[0059] Reference Figures 1 to 7 As shown, in this implementation scheme, the angle rotation mechanism includes:

[0060] The upper end of the fixed frame rod 23 is fixedly installed on the inner top wall of the center of the dumping vehicle body 1, and the lower end surface of the fixed frame rod 23 is fixedly connected to the central fixed sleeve 8. The smooth dividing surface of the threaded surfaces on both sides of the bidirectional threaded rod 9 is rotatably sleeved inside the central fixed sleeve 8.

[0061] The outer surfaces of the two sides of the central fixing sleeve 8 are symmetrically hinged with a first hinge rod 21. The other end of the first hinge rod 21 away from the central fixing sleeve 8 is hinged with a second hinge rod 22. The second hinge rod 22 is hinged on one side of the outer surface of the L-shaped overturning rod 19.

[0062] In this embodiment, the operation procedure of the angle rotation mechanism is as follows:

[0063] The central fixing sleeve 8 is fixed to the lower end of the fixing frame rod 23. The smooth section of the bidirectional threaded rod 9 rotates inside the central fixing sleeve 8, thus serving as a fixed reference for the angle rotation mechanism. When the displacement sleeve 14 moves inward, the hinge point of the first hinge rod 21 and the second hinge rod 22 moves closer to the center. The included angle between the two rods decreases as the displacement sleeve 14 and the vertical fixed rod 17 move towards the center. Through the lever action, the L-shaped shovel rod 19 is pulled to rotate clockwise around the fixed axis 24, thereby reducing the horizontal included angle.

[0064] Adaptive Angle Range and Material Response:

[0065] Gathering Angle: When the angle between the L-shaped shovel lever 19 and the horizontal direction decreases, the shovel insert 20 is in a retracted posture, gathering the scattered materials at the edge, thereby eliminating the dead angle of overturning and throwing;

[0066] Peeling angle: When the angle between the L-shaped shovel bar 19 and the horizontal direction increases, the shovel insert 20 spreads out, peeling the centrally compacted material to the edge, thereby increasing the looseness of the material and facilitating oxygen penetration.

[0067] The angle rotation mechanism of this soil turning and turning device is noteworthy because it requires no additional power and can achieve angle self-adaptation through mechanical linkage. Compared with devices that manually adjust the angle, it can significantly improve operating efficiency, reduce human error, and dynamically adjust the angle according to the lateral direction, thereby improving the processing capacity of materials in different pile states, including loose and compacted materials.

[0068] Example 2: Based on Example 1, referring to... Figures 1 to 4 As shown in this embodiment: a ladder 3 is fixedly installed on the side surface of the dumping vehicle 1 near the motor 5, and an equipment through slot is opened on the side surface of the dumping vehicle 1 near the ladder 3, and the rack and pinion chain 12 is driven inside the equipment through slot.

[0069] A baffle 4 is fixedly connected to one end of the ladder 3 near the equipment channel.

[0070] In this embodiment, the ladder 3 is fixedly installed on one side surface of the dump truck body 1. The operator can enter the operating room 2 or check the working status of the rack and pinion chain 12 in the equipment through slot area through the ladder 3. The equipment through slot can also facilitate the operator to inspect the rack and pinion chain 12. In addition, the load-bearing capacity of the ladder 3 can meet the needs of two people maintaining it at the same time.

[0071] The baffle 4 is made of stainless steel and is fixed to the end of the ladder 3 with bolts. It can completely cover the equipment channel, which can prevent fermentation materials from splashing into the transmission mechanism and provide shielding protection for the operators using the ladder 3, avoiding the operator's feet from slipping and falling into the transmission mechanism and causing an operational accident. This forms a closed protection. In addition, the surface of the baffle 4 is coated with a wear-resistant coating, which can resist the impact and wear of materials and improve the service life of the baffle 4.

[0072] Reference Figures 1 to 8 As shown in this embodiment: four sliding grooves 15 are evenly opened on the top wall of the turning vehicle body 1. Sliding rods 16 are slidably connected inside the sliding grooves 15. The lower ends of the sliding rods 16 are fixedly connected to the upper surfaces of the two sets of displacement sleeves 14 on both sides.

[0073] Specifically, the four sets of sliding grooves 15 are arranged in a rectangular shape. The vertical fixed rod 17 is slidable by the displacement sleeve 14. The vertical fixed rod 17 simultaneously drives the sliding rod 16 to slide in the sliding groove 15, which further ensures the lateral movement direction of the overturning mechanism and the angle rotation mechanism and has a limiting and guiding function.

[0074] In addition, it is worth noting that the bottom of the chute 15 is equipped with shock-absorbing rubber pads, and the four sets of sliding rods 16 are symmetrically distributed to absorb the high-frequency vibrations during equipment operation. This disperses the radial force of the bidirectional threaded rod 9 into the frame of the turning vehicle body 1, reducing the impact on the fermentation tank foundation, reducing noise, improving the working environment, and avoiding uneven wear of the bidirectional threaded rod threads.

[0075] Thus, the guiding devices of the chute 15 and slide bar 16 of this soil turning and dumping device reduce the positioning error of the turning mechanism and the rate of material leakage at the edge, thereby ensuring the accuracy of the material pushing position.

[0076] It should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should also be within the scope of protection of this invention.
