Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production equipment technology, specifically to a production device for organic fertilizer fermentation based on poultry and livestock manure. Background Technology

[0002] Organic fertilizers are carbonaceous materials made from resources rich in organic matter, such as animal and plant remains and excrement, through fermentation and decomposition. These include human excrement, manure, and compost. Their nutrients are slowly released after being decomposed by microorganisms, and they improve soil structure, enhance water and fertilizer retention capacity, regulate soil microecological balance, and thus improve the quality of agricultural products and soil productivity.

[0003] In the production process of organic fertilizer made from poultry and livestock manure, in order to ensure that the fertilizer has sufficient contact with air and improve fermentation efficiency, a turning machine is generally used to turn the fertilizer, thereby enabling the fertilizer to have sufficient contact with air. The structure of the existing track-type turning machine can refer to a rack and pinion track-type turning machine disclosed in CN205473439U. When in use, the turning machine moves on the track and turns the fertilizer through the stirring component (referred to as the turning arm in this application).

[0004] In existing compost turning machines, the turning of fertilizer relies on the rotation of the mixing components to agitate the fertilizer. Because the organic fertilizer made from livestock manure has a certain moisture content, under certain conditions, localized areas of the organic fertilizer may harden and clump together, and the thickness of these hardened clumps may be relatively large. When the mixing components turn over the hardened organic fertilizer clumps, the following problems may occur: the turning resistance is high, leading to a surge in motor load and damage to electrical components; and the fertilizer is not sufficiently agitated when turning over the clumped area, resulting in uneven oxygen distribution and hindering aerobic fermentation. Summary of the Invention

[0005] The purpose of this invention is to provide a production device for organic fertilizer fermentation based on poultry and livestock manure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a production apparatus for organic fertilizer fermentation based on poultry and livestock manure, comprising: Walking frame; A traveling mechanism, mounted on the traveling frame, is used to drive the traveling frame to move along a preset track; The tumbling drive shaft is horizontally rotatably connected to the bottom of the walking frame and is driven synchronously by the walking mechanism; At least one tumbling and throwing component, the tumbling and throwing component comprising: A fixed sleeve is fixedly fitted around the periphery of the tumbling drive shaft; The fixed arm is vertically fixed to the periphery of the fixed sleeve at one end, and has a hollow cavity inside. A floating arm is slidably connected to the other end of the fixed arm along the axial direction of the fixed arm via multiple connecting columns; The tilting arm is hinged at one end to the floating arm; A depth adaptive adjustment mechanism, connected to the tilting arm and the fixed arm, is configured to drive the floating arm to move the tilting arm toward the fixed sleeve when the resistance on the tilting arm increases, so as to reduce the tilting depth.

[0007] Furthermore, the depth adaptive adjustment mechanism includes: A hollow cylinder is fixed to the end of the floating arm away from the fixed arm, and its axis is perpendicular to the axis of the fixed arm. The first piston is slidably and sealingly installed inside the hollow cylinder, and forms a first cavity with one side space of the hollow cylinder's inner cavity; The second piston is slidably installed in the hollow cavity of the fixed arm and forms a second cavity with the lower space of the hollow cavity. One end of the connecting column is fixedly connected to the second piston. A transmission connector is connected between the tilting arm and the first piston to convert the rotation of the tilting arm into the linear motion of the first piston. The hose is connected at both ends to the fixed arm and the hollow cylinder respectively, so that the first cavity and the second cavity are in a communication state, and the first cavity and the second cavity are filled with hydraulic medium. When the tilting arm is resisted and rotates towards the floating arm, the transmission connector drives the first piston to squeeze the hydraulic medium in the first cavity, causing the hydraulic medium to flow into the second cavity through the hose, and pushing the second piston and connecting column to move towards the fixed sleeve.

[0008] Furthermore, the transmission connection includes: The thrust rod has one end fixedly connected to the first piston on the same axis, and the other end slidably extends out of the closed end of the hollow cylinder; A sliding pin is fixedly connected to one end of the thrust rod that protrudes from the hollow cylinder; The protrusion is fixed to the side of the throwing arm facing the hollow cylinder. The protrusion has a groove for the push rod to pass through freely and an oblong hole for the sliding pin to slide. The length direction of the oblong hole is consistent with the length direction of the throwing arm.

[0009] Furthermore, the cross-sectional dimensions of the first cavity are larger than those of the second cavity.

[0010] Furthermore, the depth adaptive adjustment mechanism also includes a return spring, which is disposed in the first cavity, with its two ends elastically abutting against the first piston and the sealing end cap fixedly installed at the open end of the hollow cylinder, respectively, to provide a return force to the first piston in the direction of the throwing arm.

[0011] Furthermore, the tumbling assembly also includes at least one support rod, one end of which is fixedly connected to the floating arm, and the other end of which slides along the axial direction of the fixed arm and passes through the fixed arm to provide support and guidance when the floating arm moves.

[0012] Furthermore, the turning and throwing assembly also includes a drilling and stirring mechanism, which is mounted on the turning and throwing arm and configured to be driven when the turning and throwing arm rotates in the direction of the floating arm to drill, stir and crush the material.

[0013] Furthermore, the drilling and stirring mechanism includes: Multiple rotating shafts are arranged at intervals along the length of the casting arm and are rotatably connected to the casting arm; The drilling and stirring part is fixedly connected to one end of the rotating shaft; A rack rod is slidably connected to the throwing arm along the length direction of the throwing arm and abuts against the surface of the connecting arm. A rack segment is provided around the periphery of the rack rod, and a gear segment is provided around the periphery of the rotating shaft. The gear segment and the rack segment are externally meshed.

[0014] Furthermore, the drilling and stirring mechanism also includes a buffer spring, which is disposed inside the tilting and casting arm. Its two ends elastically abut against the rack rod and the tilting and casting arm, respectively, to provide the rack rod with an elastic preload to maintain contact with the surface of the connecting arm.

[0015] Furthermore, the walking mechanism includes: Two traveling shafts are horizontally rotatably connected to the bottom of the traveling frame; The traveling wheels are installed at both ends of the traveling axle and are used to cooperate with the external track; The motor is mounted on the walking frame, and its output shaft is driven to the walking shaft through a chain drive mechanism. The tumbling drive shaft is connected to one of the traveling shafts via a chain drive mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when organic fertilizer hardens and clumps, the resistance to the turning arm is relatively large, which triggers the action of the depth adaptive adjustment mechanism, allowing the turning arm to move towards the fixed sleeve. This reduces the turning depth of the organic fertilizer. Since the resistance of the organic fertilizer is directly proportional to the turning depth, when the turning depth is reduced, the resistance of the organic fertilizer on the turning arm is reduced, allowing the turning arm to turn the upper layer of the hardened organic fertilizer. This is equivalent to reducing the turning depth of the turning arm. Through repeated turning, the hardened organic fertilizer is broken up when turned by the turning arm 7, allowing air to fully enter the hardened organic fertilizer and improving fermentation efficiency. In addition, since the turning depth is adaptively adjusted by a single turning arm, the other turning arms are not affected, so it will not have a significant impact on the overall turning efficiency, reducing the load on the motor and improving the fermentation efficiency. 2. In this invention, each turning and casting component is an independent adaptive unit, and its hydraulic system (first chamber, second chamber, hose) is independent of each other. The depth adjustment of one turning and casting arm will not affect other turning and casting arms. When a turning and casting arm encounters a hard block and automatically reduces its depth and starts drilling and stirring, the other turning and casting arms can still maintain their original relatively deep turning and casting depth and continue to perform efficient turning and casting operations. This "single-point failure does not affect the whole" design avoids reducing the overall efficiency of the equipment due to local problems, achieving high overall turning and casting efficiency while precisely handling local hard blocks. 3. In this invention, when the turning arm swings, it triggers the movement of the rack rod sliding in the sliding hole, which in turn causes the rack segment and the gear segment to mesh and drive the rotating shaft to rotate, so that the drilling and stirring part can rotate. Then, when the turning arm swings, the drilling and stirring part can drill and stir the surface of the hardened and clumped organic fertilizer, which helps to break up the organic fertilizer so that the air can fully contact the organic fertilizer.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-12This invention provides a technical solution: a production device for organic fertilizer fermentation based on poultry and livestock manure. This device is used to turn and compost organic fertilizer. It includes a walking frame 1, with two walking shafts horizontally rotatably connected to the bottom of the walking frame 1 via multiple bearing seats. Each end of the walking shaft is equipped with a walking wheel 3, which engages with an external track, allowing the walking frame 1 to roll on the track and thus move horizontally. A motor 2 is installed on each of the top two sides of the walking frame 1. The motor shaft of the motor 2 is connected to the two walking shafts via a sprocket and a chain. The two motors 2 are powered by an external power module. When the two motors 2 are powered on, the motor shafts rotate, which drives the two walking shafts to rotate. This causes the four walking wheels 3 to roll on the track, allowing the walking frame 1 to move. The bottom of the walking frame 1 has support arms 4 vertically mounted at both ends. The lower ends of the two support arms 4 are horizontally rotatably connected to the turning drive shaft 5. The two ends of the turning drive shaft 5 are connected to the two ends of one of the walking shafts through sprockets and chains, so that when the walking shaft rotates, it can drive the turning drive shaft 5 to rotate. refer to Figure 1 , Figure 2 and Figure 3 Multiple fixed sleeves 6 arranged in a row are fixedly sleeved on the periphery of the turning and throwing drive shaft 5. Fixed arms 8 are vertically fixed to the periphery of the fixed sleeves 6. The fixed arms 8 are hollow inside. A connecting post 11 is coaxially inserted at the end of the fixed arm 8 away from the fixed sleeves 6. The connecting post 11 can slide freely along the axial direction of the fixed arm 8. A floating arm 9 is coaxially fixed to the lower end of the connecting post 11. A connecting arm 12 is vertically fixed to the periphery of the floating arm 9. A turning and throwing arm 7 is hinged at the end of the connecting arm 12 away from the floating arm 9. The axis of the hinge shaft of the turning and throwing arm 7 on the connecting arm 12 is parallel to the axis of the fixed sleeve 6. Combination Figures 4 to 12 As shown, a hollow cylinder 10 is fixedly connected to the end of the floating arm 9 away from the fixed sleeve 6. The axial direction of the hollow cylinder 10 is perpendicular to the axial direction of the fixed sleeve 6. The end of the hollow cylinder 10 away from the turning arm 7 is open, and a sealing end cap 15 is fixedly installed at the open end. A first piston 22 is slidably installed inside the hollow cylinder 10. The periphery of the first piston 22 is in a sealed state with the inner wall of the hollow cylinder 10. Several sealing rings are installed on the periphery of the first piston 22, which further improves the sealing performance of the contact surface between the first piston 22 and the hollow cylinder 10. A thrust rod 17 is coaxially fixedly connected to the end face of the first piston 22. The thrust rod 17 passes through the end face of the closed end of the hollow cylinder 10 and can slide freely on the hollow cylinder 10. Combination Figures 4 to 12 As shown, especially the reference Figure 7 , Figure 9A sliding pin 26 is fixedly connected to one end of the thrust rod 17 that protrudes from the hollow cylinder 10. A protrusion 16 is fixedly connected to one side wall of the throwing arm 7 facing the hollow cylinder 10. The wall of the protrusion 16 has a groove for the thrust rod 17 to pass freely, and the wall of the protrusion 16 also has an oblong hole 18 for the sliding pin 26 to be inserted. The length direction of the oblong hole 18 is consistent with the length direction of the throwing arm 7, and is perpendicular to the axis of the hinge axis of the throwing arm 7 on the connecting arm 12. Thus, when the throwing arm 7 rotates along the hinge point with the connecting arm 12, it will drive the sliding pin 26 to slide in the oblong hole 18, thereby enabling the thrust rod 17 to drive the first piston 22 to move in the inner cavity of the hollow cylinder 10. Combination Figures 4 to 12 As shown, especially the reference Figure 5 , Figure 7 and Figure 8 A second piston 24 is slidably installed in the inner cavity of the fixed arm 8. The second piston 24 can slide freely in the inner cavity of the fixed arm 8. The upper end of the connecting column 11 passes through the fixed arm 8 and is coaxially fixed with the second piston 24. The first piston 22 and the sealing end cap 15 form a first cavity in the inner cavity of the hollow cylinder 10. The second piston 24 divides the inner cavity of the fixed arm 8 into a second cavity. A flexible hose 13 is connected between the fixed arm 8 and the sealing end cap 15. The two ends of the flexible hose 13 are respectively connected to the first cavity and the second cavity. The two chambers and hose 13 are filled with hydraulic oil. When the first piston 22 moves toward the sealing end cap 15, the first piston 22 will compress the hydraulic oil in the first chamber, so that the hydraulic oil enters the second chamber through the hose 13. At this time, the molecular weight in the second chamber increases, which in turn increases the hydraulic pressure on the second piston 24, which in turn moves the second piston 24 toward the adjacent fixed sleeve 6, and can drive the connecting column 11 to move toward the fixed sleeve 6 simultaneously, so that the throwing arm 7 can move toward the fixed sleeve 6. Furthermore, to ensure that the first piston 22 can promptly drive the tilting arm 7 to move, the cross-sectional dimension of the first cavity can be set to be larger than that of the second cavity. This allows the tilting arm 7 to move a greater distance than the first piston 22 when the first piston 22 has a shorter stroke. Additionally, since the rigidity of a single connecting column 11 may be insufficient to overcome the resistance encountered by the tilting arm 7 during tilting, potentially causing deformation, in this embodiment, at least two first lugs can be welded to the periphery of the floating arm 9. A support rod 14 is fixedly mounted on each of the first lugs. Two second lugs corresponding to the first lugs are welded to the periphery of the fixed arm 8, with the support rod 14 located away from the first lugs. One end of the block is inserted into the second ear block, and the support rod 14 can slide freely along the axial direction of the fixed arm 8 on the second ear block. In addition, the end of the support rod 14 that passes through the second ear block is threaded with a limit nut. Through the limit nut and the limit of the second ear block, the fixed arm 8 and the floating arm 9 have a relatively stable connection. Furthermore, a return spring 23 is installed in the inner cavity of the hollow cylinder 10. The return spring 23 is located in the first cavity, and the two ends of the return spring 23 elastically abut against the end face of the sealing end cap 15 and the end face of the first piston 22 respectively. In the natural state, the return spring 23 is in a pre-compressed state and has a certain elastic potential energy, so that it gives the first piston 22 the potential energy to move in the direction of the throwing arm 7. Combination Figures 4 to 12As shown, a plurality of rotating shafts 25 are rotatably connected to the side wall of the tilting arm 7 facing away from the hollow cylinder 10. The plurality of rotating shafts 25 are equally spaced along the length of the tilting arm 7. One end of the rotating shaft 25 protrudes from the tilting arm 7 and is coaxially fixed to a drilling and stirring part 20. The end of the drilling and stirring part 20 away from the tilting arm 7 is pointed. A gear segment is formed on the periphery of the other end of the rotating shaft 25. A protrusion 16 has a receiving cavity for the end of the rotating shaft 25 with the gear segment to pass freely through, and the surface of the protrusion 16 is... A sliding hole 27 is provided, which communicates with the receiving cavity. A rack rod 19 is slidably installed in the sliding hole 27, and the rack rod 19 can slide freely along the length of the throwing arm 7 within the sliding hole 27. A rack segment is provided around the periphery of the rack rod 19, and the rack segment is externally meshed with the gear segments on all the rotating shafts 25. Thus, when the rack rod 19 slides within the sliding hole 27, the rack segment on the rack rod 19 will mesh with the gear segments on all the rotating shafts 25. The step meshing transmission drives the rotating shaft 25 to rotate. When the rotating shaft 25 rotates, it will synchronously drive the drilling and stirring part 20 to rotate. The end of the rack rod 19 that passes through the sliding hole 27 is spherical and abuts against the surface of the connecting arm 12. A buffer spring 21 is installed in the sliding hole 27. The two ends of the buffer spring 21 elastically abut against the inner bottom wall of the sliding hole 27 and the end face of the rack rod 19 respectively. The buffer spring 21 is in a compressed state and imparts potential energy to the rack rod 19 to move towards the connecting arm 12, so that the end of the rack rod 19 always maintains abutting connection with the surface of the connecting arm 12. When the throwing arm 7 swings along the hinge of the connecting arm 12 towards the floating arm 9, as the swing amplitude increases, the squeezing force on the end of the rack rod 19 by the surface of the connecting arm 12 increases, which will cause the rack rod 19 to generate potential energy to move towards the inside of the sliding hole 27 and begin to compress the buffer spring 21. The buffer spring 21 then accumulates elastic potential energy.

[0021] The working principle of this embodiment is as follows: when the external power module is turned on, the motor 2 is powered on and rotates. The motor shafts of the two motors 2 rotate and drive the two walking shafts to rotate synchronously and in the same direction through the sprockets and chains, so that the walking wheels 3 rotate and the walking frame 1 rolls on the external track, so that the walking frame 1 can move. During the movement, the rotation of the walking shafts will drive the turning drive shaft 5 to rotate through the transmission of the sprockets and chains, thereby driving all the fixed sleeves 6 to rotate. When the fixed sleeve 6 rotates, the turning arm 7 will rotate. During the rotation of the turning arm 7, the organic fertilizer under the walking frame 1 can be turned over. If the organic fertilizer hardens and clumps during the turning, the turning arm 7 will experience greater resistance than the elastic pushing force of the return spring 23 on the first piston 22 and the hydraulic pressure in the first cavity. At this time, the turning arm 7 will rotate towards the floating arm 9 under the resistance of the organic fertilizer. During the rotation, the sliding pin 26 will slide in the waist-shaped hole 18, which will cause the push rod 17 to drive the first piston 22 to slide in the hollow cylinder 10 and cause the first piston 22 to squeeze the hydraulic oil in the first cavity of the hollow cylinder 10. The hydraulic oil will enter the second cavity through the hose 13. At this time, the molecular weight of the hydraulic oil in the second cavity increases, which will increase the hydraulic pressure of the second piston 24. As a result, the second piston 24 will move towards the fixed sleeve 6 in the inner cavity of the fixed arm 8. When the second piston 24 moves, it pulls the connecting column 11 to move, so that the connecting column 11 can pull the floating arm 9 to move towards the fixed sleeve 6, and thus the turning arm 7 can move towards the fixed sleeve 6. This reduces the turning depth of the turning arm 7 on the organic fertilizer. Since the resistance of the organic fertilizer is directly proportional to the turning depth, when the turning depth is reduced, the resistance of the organic fertilizer on the turning arm 7 is reduced, which allows the turning arm 7 to turn over the upper layer of hardened and clumped organic fertilizer, which is equivalent to reducing the turning depth of the turning arm 7. Through repeated turning, the hardened and clumped organic fertilizer can be broken up by the turning arm 7, so that air can fully enter the hardened and clumped organic fertilizer, improving the fermentation efficiency. In addition, since the turning depth of a single turning arm 7 is adaptively adjusted, the other turning arms 7 are not affected, so it will not have a significant impact on the overall turning efficiency. Furthermore, when the turning arm 7 is performing adaptive depth adjustment, the rack rod 19 will slide in the sliding hole 27, causing the rack segment on the rack rod 19 to mesh synchronously with the gear segments on all the rotating shafts 25 to drive the rotating shafts 25 to rotate. When the rotating shafts 25 rotate, they will synchronously drive the drilling and stirring part 20 to rotate. When the drilling and stirring part 20 rotates, it will produce a drilling and stirring effect on the surface of the hardened and clumped organic fertilizer, so that the hardened and clumped organic fertilizer is subjected to the squeezing force of the drilling and stirring part 20, so that at least a part of the organic fertilizer can be broken up, and at this time the buffer spring 21 accumulates elastic potential energy. After the throwing arm 7 is thrown, it rotates to the top of the fixed sleeve 6. As the resistance of the organic fertilizer on the throwing arm 7 disappears, the elastic potential energy stored in the return spring 23 will begin to be released, driving the first piston 22 to move towards the throwing arm 7. This increases the volume of the first cavity, causing the hydraulic oil in the second cavity to flow back into the first cavity through the hose 13. This causes the second piston 24 to drive the connecting column 11 to move away from the fixed sleeve 6, and simultaneously drives the floating arm 9 to move away from the fixed sleeve 6. This allows the throwing arm 7 to move away from the fixed sleeve 6, thus achieving the reset of the throwing arm 7. In addition, the elastic potential energy stored in the buffer spring 21 is released, allowing the rack rod 19 to move towards the outside of the sliding hole 27, thus keeping the end of the rack rod 19 in contact with the connecting arm 12.
