A heating, stirring, and composting device for garden dead branches and fallen leaves

Abstract

This utility model relates to the technical field of landscape garden maintenance equipment, and in particular to a heating, stirring, and composting device for garden dead branches and leaves. It includes a composting mechanism with a feeding hood at the top and a plate inserted into the hood. It also includes a stirring mechanism and a crushing mechanism located outside the stirring mechanism. Both the stirring and crushing mechanisms are located inside the composting mechanism. The stirring frame drives multiple stirring tubes to stir the dead branches and leaves inside the composting chamber. Simultaneously, a transmission gear drives a rotating sleeve to rotate, which in turn drives a crushing frame to revolve around the stirring frame. The rotating gear on the crushing frame also rotates on its own axis. This rotation of the gears forces the clumps of dead branches and leaves against the inner wall of the composting chamber, thus breaking up the clumps of leaves that have formed during composting. This accelerates airflow within the composting chamber, thereby promoting the growth of aerobic bacteria.

Description

Technical Field

[0001] This utility model relates to the technical field of landscape garden maintenance equipment, and in particular to a heating, stirring and composting device for garden dead branches and fallen leaves. Background Technology

[0002] The decomposition of garden dead branches and fallen leaves is mainly used to transform garden waste into organic fertilizer or cultivation substrate through crushing, decomposition and other processes. During the decomposition process, the crushed materials are mixed with microbial agents, livestock and poultry manure and other materials for aerobic high-temperature composting.

[0003] According to the patent document with publication number CN215288574U, the crushed dead branches and leaves are sent into the box for composting and fermentation. During the process of sending them into the box, water is sprayed on the dead branches and leaves to provide humidity for composting and fermentation. During the composting and fermentation process, the air flow is controlled to carry out anaerobic composting and fermentation and aerobic composting and fermentation. Then, the branches and leaves that have completed composting and fermentation are sent out using a screw conveyor.

[0004] The patent document does not include a turning or stirring structure during the composting process. As a result, the crushed dead branches and leaves tend to clump together during composting, which may affect airflow and inhibit the growth of aerobic bacteria. In addition, if livestock and poultry manure is mixed in with the dead branches and leaves, the nutrients will not be evenly distributed, which may lead to uneven composting and uneven temperature rise. Utility Model Content

[0005] The purpose of this invention is to provide a heating, stirring, and composting device for garden dead branches and fallen leaves in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A garden dry branches and fallen leaves heating, stirring and composting device includes a composting mechanism, a feeding hood at the top of the composting mechanism, a plate inserted into the feeding hood, a stirring mechanism, and a crushing mechanism on the outside of the stirring mechanism. Both the stirring mechanism and the crushing mechanism are located inside the composting mechanism.

[0008] The stirring mechanism includes two stirring frames, with multiple stirring tubes distributed circumferentially between the two stirring frames. Each stirring tube is equipped with a heating wire. A rotating shaft is fixed at the far end of each of the two stirring frames. A stirring motor is fixed at the input end of the rotating shaft, and a drive gear is fixed on each rotating shaft. Three transmission gears mesh on the outside of each drive gear.

[0009] The crushing mechanism includes two crushing frames, each of which is rotatably connected to the outside of the rotating shaft. A rotating sleeve is fixed on the side of the crushing frame away from the stirring tube. A crushing gear ring for meshing with three transmission gears is fixed on the inner wall of each rotating sleeve. Six rotating cutter wheels are provided between the two crushing frames. A rotating gear ring is provided at the end of each rotating cutter wheel that extends out of the crushing frame. Six rotating gears mesh on the inner side of each rotating gear ring. Each rotating gear is fixedly connected to the end of the rotating cutter wheel that extends out of the crushing frame.

[0010] Preferably, the composting mechanism includes a fermentation box with an open top and an arc-shaped opening at the bottom. The bottom of the fermentation box is equipped with two symmetrical arc-shaped sealing plates. Hydraulic cylinders are fixed on both the front and rear sides of the composting box to move the two arc-shaped sealing plates away from or closer to each other.

[0011] Preferably, each crushing rack has a through hole for the rotating blade to pass through, and protective covers are fixed on both sides inside the fermentation box, with the crushing rack rotatably connected to the lower side of the protective cover.

[0012] Preferably, two rotating gear rings are fixed on both sides inside the composting box, and the crushing frame is rotatably connected to both sides of the composting box near the rotating sleeve.

[0013] Preferably, support seats are fixed on both sides of the composting box, and the transmission gear is rotatably connected to the support seats.

[0014] Preferably, a water inlet pipe is provided on the side of the feed hood away from the insert plate, and two water spray pipes are fixed at one end of the water inlet pipe that passes through the feed hood, and the two water spray pipes are located at the front and rear sides of the inside of the feed hood respectively.

[0015] Preferably, the composting box has arc-shaped slots on both sides for two arc-shaped sealing plates to pass through, and the two arc-shaped sealing plates are slidably connected in the two arc-shaped slots respectively.

[0016] The beneficial effects compared with the existing technology are as follows: The stirring frame drives multiple stirring tubes to stir the dead branches and leaves in the composting box. At the same time, the transmission gear also drives the rotating sleeve to rotate. The rotating sleeve drives the crushing frame to revolve around the stirring frame, and the rotating gear on the crushing frame also rotates on its own axis. The rotation of the rotating gear squeezes the clumps of dead branches and leaves onto the inner wall of the composting box, thereby rotating and crushing the clumps of dead branches and leaves that have clumped due to composting inside the composting box, accelerating the air flow inside the dead branches and leaves, and thus accelerating the growth of aerobic bacteria.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-10 As shown, a garden twig and leaf heating and stirring composting device includes a composting mechanism 5. The top of the composting mechanism 5 is provided with a feeding hood 8, and a plate 9 is inserted into the feeding hood 8. A water inlet pipe 6 is provided on the side of the feeding hood 8 away from the plate 9. Two water spray pipes 7 are fixed at one end of the water inlet pipe 6 that passes through the feeding hood 8. The two water spray pipes 7 are located on the front and rear sides inside the feeding hood 8, respectively. The device also includes a stirring mechanism 1. A crushing mechanism 2 is provided on the outside of the stirring mechanism 1. Both the stirring mechanism 1 and the crushing mechanism 2 are located inside the composting mechanism 5.

[0033] In this embodiment: the composting mechanism 5 includes a composting box 51. The top of the composting box 51 is an open structure, and the bottom of the composting box 51 is an arc-shaped opening. The bottom of the composting box 51 is provided with two symmetrical arc-shaped sealing plates 53. Hydraulic cylinders 52 are fixed on both the front and rear sides of the composting box 51 to drive the two arc-shaped sealing plates 53 away from or close to each other. Arc-shaped slots for the two arc-shaped sealing plates 53 to pass through are opened on both sides of the composting box 51. The two arc-shaped sealing plates 53 are slidably connected in the two arc-shaped slots respectively. The extension and retraction parts of the hydraulic cylinders 52 push the arc-shaped sealing plates 53 out of the arc-shaped slots of the composting box 51, thereby opening the arc-shaped opening at the bottom of the composting box 51, and then the composted dead branches and leaves can be poured out.

[0034] In this embodiment: the stirring mechanism 1 includes two stirring frames 11, with multiple stirring tubes 12 circumferentially distributed between the two stirring frames 11. Each stirring tube 12 is equipped with a heating wire. A rotating shaft is fixed at the far end of each of the two stirring frames 11. A stirring motor 15 is fixed at the input end of the rotating shaft, and a drive gear 13 is fixed on each rotating shaft. Three transmission gears 14 mesh with the outside of each drive gear 13. Support seats 3 are fixed on both sides of the composting box 51. The transmission gears 14 are rotatably connected to the support seats 3. The rotating part of the stirring motor 15 drives the stirring frames 11 to rotate through the rotating shaft. The rotation of the two stirring frames 11 drives the stirring tubes 12 to rotate inside the composting box 51, thereby turning over the dead branches and leaves inside the composting box 51. At the same time, the heating wire in each stirring tube 12 heats the dead branches and leaves, thereby allowing the dead branches and leaves to reach a suitable composting temperature.

[0035] In this embodiment: the crushing mechanism 2 includes two crushing frames 23, and each crushing frame 23 is rotatably connected to the outside of the rotating shaft. A rotating sleeve 21 is fixed on the side of the crushing frame 23 away from the stirring tube 12. A crushing gear ring 22 for meshing with three transmission gears 14 is fixed on the inner wall of each rotating sleeve 21. Six rotating cutter wheels 24 are provided between the two crushing frames 23. A rotating gear ring 26 is provided at the end of each rotating cutter wheel 24 that extends out of the crushing frame 23. Six rotating gear rings are meshed on the inner side of each rotating gear ring 26. Gears 25, each rotating gear 25 is fixedly connected to one end of the rotating blade 24 extending out of the crushing frame 23. Each crushing frame 23 has a through hole for the rotating blade 24 to pass through. Protective covers 4 are fixed on both sides inside the fermentation box 51, and the crushing frame 23 is rotatably connected to the lower side of the protective cover 4. Two rotating gear rings 26 are fixed on both sides inside the composting box 51. The crushing frame 23 is rotatably connected to both sides of the composting box 51 near the rotating sleeve 21. The rotating shaft of the stirring frame 11 is used for rotation. The drive gear 13 is driven to rotate synchronously. Through the meshing of the drive gear 13 and the three transmission gears 14, the crushing gear ring 22 is driven to rotate. At the same time, the rotation of the crushing gear ring 22 drives the rotating sleeve 21 to rotate synchronously. The rotation of the rotating sleeve 21 drives the crushing frame 23 to rotate outside the mixing frame 11. The two crushing frames 23 drive the six rotating cutter wheels 24 to revolve around the outside of the mixing frame 11. At this time, the rotating gear 25 of the rotating cutter wheel 24 extends out of one end of the crushing frame 23. It will rotate along the rotating gear ring 26. Since the rotating gear 25 meshes with the rotating gear ring 26, when the rotating gear 25 rotates along the rotating gear ring 26, the rotating gear 25 will rotate on its own axis. Then, when the crushing frame 23 revolves around the stirring frame 11, the rotating gear 25 on the crushing frame 23 will also rotate on its own axis. Through the rotation of the rotating gear 25, the clumps of dead branches and fallen leaves are squeezed onto the inner wall of the composting box 51, so that the clumps of dead branches and fallen leaves inside the composting box 51 that have clumped due to composting can be rotated and crushed.

[0036] Working principle: First, pull out the insert plate 9 on the feed hood 8, and then pour the crushed dead branches and leaves into the feed hood 8 from the top. The dead branches and leaves will fall into the composting tank 51 along the feed hood 8. At the same time, water mixed with bacteria is supplied to the water inlet pipe 6. At this time, the water will enter the two spray pipes 7 through the water inlet pipe 6. Then, as the dead branches and leaves fall into the composting tank 51, the water will mix with the dead branches and leaves, and at the same time, it will provide suitable humidity conditions for composting.

[0037] In addition, when the dead branches and leaves enter the composting box 51, the rotating part of the stirring motor 15 drives the stirring frame 11 to rotate through the rotating shaft. The rotation of the two stirring frames 11 drives the stirring tube 12 to rotate inside the composting box 51, thereby turning over the dead branches and leaves inside the composting box 51. At the same time, the heating wire in each stirring tube 12 is used to heat the dead branches and leaves, thereby enabling the dead branches and leaves to reach a suitable composting temperature.

[0038] Furthermore, when the two stirring frames 11 drive the multiple stirring tubes 12 to rotate, the rotating shaft of the stirring frame 11 synchronously drives the drive gear 13 to rotate. Through the meshing transmission of the drive gear 13 and the three transmission gears 14, the crushing gear ring 22 is driven to rotate. At the same time, the rotation of the crushing gear ring 22 drives the rotating sleeve 21 to rotate synchronously. The rotation of the rotating sleeve 21 drives the crushing frame 23 to rotate outside the stirring frame 11. The two crushing frames 23 drive the six rotating cutter wheels 24 to revolve around the outside of the stirring frame 11. At this time, the rotating gear 24 of the rotating cutter wheel 24 extends out of one end of the crushing frame 23. 5 will rotate along the rotating gear ring 26. Since the rotating gear 25 meshes with the rotating gear ring 26, when the rotating gear 25 rotates along the rotating gear ring 26, the rotating gear 25 will rotate on its own axis, improving the overall stirring efficiency. During this process, aerobic bacteria in the composting box 51 can grow, allowing the aerobic bacteria in the dead branches and leaves to undergo aerobic composting. After a certain period of aerobic composting, the dead branches and leaves inside the composting box 51 can undergo anaerobic composting. At this time, the insert plate 9 on the feed hood 8 is inserted back, thereby reducing the air exchange between the inside of the composting box 51 and the outside, and then accelerating the growth of anaerobic bacteria in the dead branches and leaves.

[0039] After the fallen leaves and branches have decomposed for a certain period of time, the stirring frame 11 drives multiple stirring tubes 12 to stir the fallen leaves and branches in the decomposition box 51. At the same time, the transmission gear 14 also drives the rotating sleeve 21 to rotate. The rotating sleeve 21 drives the crushing frame 23 to revolve around the stirring frame 11. The rotating gear 25 on the crushing frame 23 also rotates on its own axis. The rotation of the rotating gear 25 squeezes the clumps of fallen leaves and branches onto the inner wall of the decomposition box 51, thereby rotating and crushing the clumps of fallen leaves and branches inside the decomposition box 51, accelerating the air flow inside the fallen leaves and branches, and thus accelerating the growth of aerobic bacteria.

[0040] After the composting is complete, the hydraulic cylinder 52 is used to push the arc-shaped sealing plate 53 out of the arc-shaped slot of the composting box 51, thereby opening the arc-shaped opening at the bottom of the composting box 51, and then the composted dead branches and leaves can be poured out.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
