Description

Technical Field

[0001] This invention relates to the field of composting, and more particularly to a mobile, highly efficient aerobic composting device for garden waste. Background Technology

[0002] Green waste is an important component of solid waste, mainly including dead branches and leaves, fallen flowers, dead roots, pruning branches of trees and flowers, grass clippings, and plant residues. The decay of dead branches and leaves can pollute the environment, so the waste is often composted. During composting, mobile devices are usually used to collect and crush the dead branches and leaves.

[0003] A search revealed Chinese patent application CN113929512A, which discloses a solar-powered composting device for garden plant waste. The device includes a base with a hollow box at its top, containing a filter plate. A motor, feed inlet, and battery are located on the top of the box. A mounting plate with a solar panel on its upper surface is positioned above the top of the box. A first rotating shaft with multiple push rods is mounted on its output end. A rotating cylinder with multiple cutting blades on its inner wall is located inside the composting chamber. The first rotating shaft is rotatably connected to the rotating cylinder via a drive mechanism. A stirring mechanism is located inside the composting chamber, and a shaking mechanism is positioned between the stirring mechanism and the filter plate. This invention enables the simultaneous rotation of the drive mechanism and the rotating mechanism, as well as the simultaneous rotation of the stirring and shaking mechanisms, achieving simultaneous crushing of plant waste, mixing of plant waste and water, composting, and cleaning of the filter plate.

[0004] When existing equipment crushes waste for composting, the crushed waste accumulates inside the equipment. After the debris is crushed, it is discharged through the pump. However, the accumulation of debris inside the equipment causes blockages, which affects the composting process. Summary of the Invention

The device comprises a support plate, a connecting seat, a turntable, a support shaft, a rotating shaft, and multiple stirring teeth. Two top blocks are distributed vertically and have mutually cooperating protrusions on their opposing surfaces. The upper top block is fixed to the bottom of the crushing mechanism. The two support plates are fixed to both sides of the lower top block and slidably connected to the grooves in the side wall of the processing box. The connecting seat is fixed to one side of the lower top block and connected to a pressure rod. The outer circumference of the turntable has a spiral moving groove, and one end of the pressure rod is slidably disposed in the moving groove. The rotating shaft is fixed to the bottom of the turntable and is rotatably supported inside the processing box by the support shaft. Multiple stirring teeth are disposed on the rotating shaft.

[0007] Preferably, the crushing mechanism includes a shaft, a guide tube, two connecting plates, multiple crushing teeth, multiple auxiliary teeth, and a crushing motor that drives the shaft to rotate. The shaft is rotatably connected to the bottom of the cover plate through bearings. The crushing motor is fixed on the cover plate and its output end is connected to the shaft. Multiple crushing teeth are distributed circumferentially along the shaft. The guide tube is fixed to both sides inside the processing box through two connecting plates. Multiple auxiliary teeth are distributed along the inner wall of the guide tube, and the crushing teeth and auxiliary teeth are alternately arranged axially.

[0008] Preferably, the connecting plate has a positioning hole, a positioning rod is slidably connected in the positioning hole, the bottom of the positioning rod is fixedly connected to the support plate, and a return spring is provided between the support plate and the connecting plate.

[0009] Preferably, the processing box is equipped with a dispersing mechanism, which is driven by an anti-blocking mechanism.

[0010] Preferably, the dispersing mechanism includes a piston cylinder, a piston, and multiple dispersing teeth. The piston cylinder is fixed on a connecting plate, the piston is slidably connected inside the piston cylinder, the positioning rod is fixedly connected to the piston, a chamber is opened near the top of the conduit, multiple dispersing teeth are disposed on the inner wall of the conduit and are made of hollow elastic material, the chamber and each dispersing tooth are connected through a guide hole, and a flexible tube is provided between the piston cylinder and the chamber.

[0011] Preferably, the moving groove is spiral-shaped, so that the pressure rod drives the turntable to rotate alternately in both directions during the up-and-down movement.

[0012] Preferably, the support shaft is connected to the rotating shaft via bearings, and both ends of the support shaft are fixed to the side wall of the processing box.

[0013] Preferably, the connecting pipe and the chip discharge pipe are both connected to the inlet and outlet of the pump body via flanges, respectively.

[0014] The beneficial effects of this invention are as follows: 1. This invention, through the setting of a crushing mechanism, a pulverizing mechanism, and an anti-clogging mechanism, utilizes a self-propelled trolley to move the device during waste composting. When the trolley reaches one side of the waste, it stops moving, allowing the waste to be transported into the processing tank through the inlet. During this process, the crushing mechanism performs initial crushing of the waste. When the crushed debris enters the pulverizing mechanism, the pulverizing mechanism is activated to further pulverize the debris, thereby improving the composting effect and preventing the waste from being hindered by its large size. After pulverization, the waste falls to the bottom of the processing tank, where the debris is discharged through a pump and a chip removal pipe. During this process, as the pulverizing mechanism further pulverizes the debris, the upper top block rotates synchronously with it. Because multiple protrusions are provided between the two top blocks to assist in lifting, the rotation of the upper top block causes the lower top block to move downwards. The receiving seat will drive the pressure rod to move downwards along with the lower top block. At this time, the pressure rod will slide in the spiral moving groove. The turntable will drive the rotating shaft to rotate under the cooperation of the pressure rod and the moving groove, thereby agitating the debris through the stirring teeth. When the lower top block moves upwards, the turntable will drive the rotating shaft to rotate in the opposite direction under the cooperation of the pressure rod and the moving groove. The reciprocating rotation of the anti-clogging mechanism can effectively loosen the accumulated debris, so that the debris can be discharged by the pump. Compared with unidirectional rotation, this application can improve the processing effect of debris through reciprocating rotation. Through the reverse movement during reciprocating rotation, the "clumps" or "net-like blockages" formed by the entanglement of fibers and flexible materials can be untied. In addition, fibrous waste (such as ropes, hair, and fabric scraps) is easy to entangle in one direction. Reciprocating rotation can effectively "loosen" them and guide them out. At the same time, reciprocating rotation helps to "loosen" and "flatten" the debris in the processing box, avoiding accumulation and compaction at the discharge port, forming an arch bridge effect. 2. This invention, through its anti-blocking and dispersing mechanisms, allows the upper block to rotate while simultaneously driving the lower block to move up and down reciprocally. The positioning rod and positioning hole work together to position the upper block's movement. When the positioning rod moves upward, it pushes the piston to slide inside the piston cylinder, increasing the internal pressure. This gas is then transported through a hose to the interior of the chamber, further increasing the internal pressure. The dispersing teeth bulge under this pressure. When the positioning rod moves downward, the piston cylinder and piston extract gas from the chamber, causing the dispersing teeth to flatten. The reciprocating bulging of the dispersing teeth effectively blocks the initially crushed debris, facilitating its distribution and improving the crushing effect. This prevents large amounts of debris from accumulating and causing significant resistance, which would otherwise hinder the crushing process. Attached Figure Description

[0017] Example 1, referring to Figures 1-7 A mobile, high-efficiency aerobic composting device for garden waste includes a self-propelled trolley 1, a pump body 9, a chip removal pipe 7, multiple support pillars 2, and a processing box 3. The processing box 3 is fixed to the self-propelled trolley 1 by the multiple support pillars 2. An inlet 4 is provided on one side of the processing box 3, and a discharge port 9 is provided at the bottom of the processing box 3. A connecting pipe 10 is connected to the pump body 8 by a flange. The chip removal pipe 7 is fixed to the other side of the pump body 8 by a flange. A crushing mechanism is provided on one side of the inner wall of the inlet 4. A cover plate 5 is bolted to the top of the processing box 3. A crushing mechanism 6 is provided between the top of the cover plate 5 and the inside of the processing box 3. An anti-blocking mechanism 15 is provided inside the processing box 3. The anti-blocking mechanism 15 is reciprocated by the unidirectional rotation of the crushing mechanism 6 to prevent the chip debris from clogging the inside of the processing box 3 and making it difficult to discharge. The anti-blocking mechanism 15 includes two top blocks 22, two support plates 29, a connecting seat 23, a turntable 24, a support shaft 26, a rotating shaft 27, and multiple stirring teeth 28. The two top blocks 22 are arranged vertically, and multiple protrusions are provided between the two top blocks 22 to cooperate in lifting. The upper top block 22 is fixed to the bottom of the crushing mechanism 6, and the two support plates 29 are fixed to both sides of the lower top block 22 by bolts. The processing box 3 has sliding grooves on both sides, and one end of the two support plates 29 is slidably connected in the sliding groove. The connecting seat 23 is fixed to one side of the lower top block 22 by bolts. A pressure rod is connected to one side of the connecting seat 23 by bolts. A spiral moving groove 25 is opened on the outer circumference of the turntable 24. One end of the pressure rod is set in the moving groove 25. The rotating shaft 27 is welded to the bottom of the turntable 24. The support shaft 26 is fixed to both sides of the processing box 3 by bolts. The support shaft 26 and the rotating shaft 27 are rotatably connected by bearings. Multiple stirring teeth 28 are fixed at equal distances on the outer circumference of the rotating shaft 27.

[0018] The working process of the anti-blocking mechanism 15: During the composting of waste, the device is moved by the self-moving trolley 1. When it reaches one side of the waste, the self-moving trolley 1 stops moving. At this time, the waste is transported into the processing box 3 through the inlet 4. During this process, the crushing mechanism performs preliminary crushing of the waste. When the crushed debris enters the crushing mechanism 6, the crushing mechanism 6 is activated. The crushing mechanism 6 further crushes the debris, thereby improving the composting effect of the waste and preventing the large size of the waste from affecting the composting process. After crushing, the waste falls to the bottom of the processing box 3, and the debris is discharged through the pump body 8 and the chip discharge pipe 7. During this process, when the crushing mechanism 6 further crushes the debris, the top block 22 above... The upper and lower top blocks 22 rotate synchronously with the crushing mechanism 6. Since there are multiple protrusions between the two top blocks 22, the upper top block 22 will drive the lower top block 22 to move downward while rotating. The connecting seat 23 will drive the pressure rod to move downward along with the lower top block 22. At this time, the pressure rod will slide in the spiral moving groove 25. The turntable 24 will drive the rotating shaft 27 to rotate under the cooperation of the pressure rod and the moving groove 25, thereby stirring the debris through the stirring teeth 28. When the lower top block 22 moves upward, the turntable 24 will drive the rotating shaft 27 to rotate in the opposite direction under the cooperation of the pressure rod and the moving groove 25. The reciprocating rotation of the anti-blocking mechanism 15 can effectively loosen the accumulated debris so that the debris can be discharged by the pump body 8.

[0019] In this invention, the crushing mechanism includes two rotating rods 11, two crushing rollers 12, two gears 14, and a crushing motor 13. The two rotating rods 11 are rotatably connected to both sides of the inlet 4 via bearings. The crushing rollers 12 are fixedly sleeved on the outer circumference of the rotating rods 11. The two gears 14 are meshed and fixedly sleeved on the rotating rods 11. The crushing motor 13 is fixed to one side of the processing box 3 by bolts, and its output end is fixedly connected to one of the rotating rods 11. When waste enters through the inlet 4, the crushing motor 13 is started, and the crushing motor 13 drives one of the rotating rods 11 to rotate. At this time, the meshing between the two gears 14 causes the other rotating rod 11 to rotate synchronously, thereby performing preliminary crushing treatment on the waste through the two crushing rollers 12.

[0020] In this invention, the crushing mechanism 6 includes a shaft 17, a guide tube 18, two connecting plates 21, multiple crushing teeth 19, multiple auxiliary teeth 20, and a crushing motor 16 for driving the shaft 17 to rotate. The shaft 17 is rotatably connected to the bottom of the cover plate 5 via bearings. The crushing motor 16 is fixed to the cover plate 5 by bolts, and its output end is fixedly connected to the shaft 17. Multiple crushing teeth 19 are fixed at equal intervals on the outer circumference of the shaft 17. The two sides of the guide tube 18 are fixed to the two sides of the inner wall of the processing box 3 via two connecting plates 21. Multiple auxiliary teeth 20 are fixed at equal intervals on the inner circumference of the guide tube 18. The crushing teeth 19 and auxiliary teeth 20 are alternately distributed to complete the secondary crushing of the waste debris after preliminary crushing through the cooperation between the crushing teeth 19 and auxiliary teeth 20.

[0021] Based on the above, in order to improve the stability of the reciprocating movement of the lower top block 22, a positioning hole is provided on the top of the connecting plate 21, and a positioning rod 31 is slidably connected to the inner wall of the positioning hole. The bottom of the positioning rod 31 is welded to the support plate 29, and a return spring 30 is welded between the support plate 29 and the connecting plate 21.

[0022] Example 2, refer to Figures 1-8 A mobile garden waste high-efficiency aerobic composting treatment device, compared with Example 1, has a dispersing mechanism 33 inside the treatment box 3, which is driven by the anti-blocking mechanism 15.

[0023] Based on the above, the dispersion mechanism 33 includes a piston cylinder 32, a piston, and multiple dispersion teeth 36. The piston cylinder 32 is fixedly connected to the connecting plate 21 by bolts, and the piston is slidably connected inside the piston cylinder 32. The positioning rod 31 is fixedly connected to the piston by bolts. The piston slides inside the piston cylinder 32 by the up and down movement of the positioning rod 31. A chamber 34 is opened near the top of the inside of the conduit 18. Multiple dispersion teeth 36 are arranged on the inner wall of the conduit 18. The dispersion teeth 36 are made of hollow elastic material. A guide hole is opened between the chamber 34 and the dispersion teeth 36. A flexible hose 35 is arranged between the piston cylinder 32 and the chamber 34.

[0024] The working process of the dispersing mechanism 33: When the upper top block 22 rotates, it drives the lower top block 22 to move up and down reciprocally. The up and down movement of the top block 22 can be positioned by the cooperation between the positioning rod 31 and the positioning hole. When the positioning rod 31 moves upward, it pushes the piston to slide inside the piston cylinder 32. At this time, the air pressure inside the piston cylinder 32 will increase, and the gas inside the piston cylinder 32 will be transported to the inside of the chamber 34 through the hose 35. The air pressure inside the chamber 34 will increase, and the dispersing teeth 36 will bulge under the action of air pressure. When the positioning rod 31 moves downward, the piston cylinder 32 and the piston will draw gas from the inside of the chamber 34. At this time, the dispersing teeth 36 will be in a flat state. The reciprocating bulging of the dispersing teeth 36 can effectively block the debris after the initial crushing, so as to facilitate the diversion of debris.
