Description

Technical Field

[0001] The present invention belongs to the technical field of garden waste treatment, and particularly relates to an integrated device for crushing and composting garden waste. Background Art

[0002] Traditional methods for treating garden waste mainly include open stacking, incineration, and simple landfill. These treatment methods not only occupy a large amount of land resources but also easily cause environmental pollution problems, such as the impact of harmful gases generated by incineration on air quality and the risk of soil and groundwater pollution caused by landfill. In addition, simple treatment methods fail to fully utilize the organic matter in garden waste, losing the opportunity to convert it into valuable resources. For example, composting can be used to convert it into organic fertilizer, which can not only improve soil structure, increase soil fertility, but also reduce the use of chemical fertilizers and promote ecological balance.

[0003] With the enhancement of environmental awareness and the development of technology, more and more research efforts are dedicated to exploring more efficient and environmentally friendly garden waste treatment technologies.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0023] As Figures 1-7 shown, a garden waste crushing and composting integrated device provided by an embodiment of the present invention includes a crushing bin 3 and a composting bin 10. A waste feed hopper 1 is provided at the top of the crushing bin 3, and support legs 14 are fixed at the bottom of the crushing bin 3. The materials input into the waste feed hopper 1 can be various garden wastes collected, such as branches, leaves, weeds, etc. Stones, plastics, metals and other sundries are removed in advance to prevent these impurities from entering the crushing and composting links and affecting the operation of the equipment and the quality of composting. A composting cavity 44 is provided inside the composting bin 10, and a discharge port 19 communicating with the bottom of the composting cavity 44 is provided on the side of the composting bin 10. The crushing bin 3 is connected to the composting bin 10 through a feeding component, and the feeding component is used to control the conveyance of the crushed garden waste in the crushing bin 3 to the composting cavity 44 of the composting bin 10. It also includes: An inner crushing shaft 25 and an outer crushing tube 29. The outer crushing tube 29 is slidably and rotatably installed in the middle of the top of the crushing bin 3. The inner crushing shaft 25 is slidably and rotatably installed inside the outer crushing tube 29. Crushing components 32 are installed on the inner crushing shaft 25 and the outer crushing tube 29 inside the crushing bin 3. A drive control assembly 2 connected to the inner crushing shaft 25 and the outer crushing tube 29 is also installed on the top of the crushing bin 3. The drive control assembly 2 is used to drive the inner crushing shaft 25 and the outer crushing tube 29 to rotate in opposite directions, and to drive the outer crushing tube 29 to move up and down. A turning and mixing component 40. The turning and mixing component 40 is arranged inside the composting bin 10. A horizontal drive assembly connected to the turning and mixing component 40 is installed on the inner top of the composting bin 10. The horizontal drive assembly is used to drive the turning and mixing component 40 to move horizontally. The turning and mixing component 40 is used to level the composting materials in the composting chamber 44. The turning and mixing component 40 is also used to mix and turn the composting materials at the lower part of the composting chamber 44 by shoveling up the materials.

[0024] In the embodiment of the present invention, the drive control assembly 2 can drive the inner crushing shaft 25 and the outer crushing tube 29 to rotate in opposite directions, and drive the outer crushing tube 29 to move up and down. In this way, the transmission mode of the crushing components 32 can be changed, and it has a better crushing effect and efficiency on the garden waste in the crushing bin 3, making the size of the crushed particles uniform (for example, crushing branches and the like into particles with a particle size of about 8 - 12 mm). The feeding assembly can control the transportation of the crushed garden waste in the crushing bin 3 to the composting chamber 44 of the composting bin 10. The horizontal drive assembly can drive the turning and mixing component 40 to move horizontally. The turning and mixing component 40 can level the composting materials in the composting chamber 44. The turning and mixing component 40 is also used to mix and turn the composting materials at the lower part of the composting chamber 44 by shoveling up the materials, which can enable reliable composting fermentation of the garden waste in the composting chamber 44.

[0025] It should be noted that turning the compost regularly can, on the one hand, make the materials inside the compost pile fully contact with oxygen, promoting the uniform distribution of microorganisms and the progress of the fermentation reaction; on the other hand, it can prevent local overheating or over - wetting of the compost pile, avoiding the occurrence of anaerobic fermentation and generating odors or affecting the quality of the compost. The frequency of turning is generally 1 - 2 times a week, and it can be determined specifically according to the actual situation of the compost. At the same time, maintain good ventilation conditions, timely discharge gases such as carbon dioxide and ammonia generated during the composting process, and maintain the gas balance inside the compost pile.

[0026] After a period of fermentation, the compost gradually matures and becomes a dark brown, soft, odorless and nutrient-rich organic fertilizer. The fermentation time varies according to different raw materials and fermentation conditions, and generally takes 2-3 months or longer. After the compost is mature, it can be screened according to the needs of subsequent processes, and fine particles with particle sizes that meet the requirements can be used as finished organic fertilizers, which can be used in soil improvement, flower cultivation, landscaping and other fields. For larger particles or incompletely decomposed materials that are screened out, they can be put back into the composting process for continued fermentation without limitation or elaboration.

[0040] Inside the crushing bin 3, there are an inner crushing shaft 25 and an outer crushing tube 29 that can rotate in reverse and move up and down. Driven by the drive control assembly 2, the inner crushing shaft 25 and the outer crushing tube 29 rotate in reverse and move up and down, achieving efficient crushing of garden waste and making the particle size uniform (about 8 - 12 mm). Specifically: When the motor three 20 starts, it drives the bevel gear one 22 to drive the bevel gear two 23 and the bevel gear three 27 to rotate in reverse, thereby making the inner crushing shaft 25 and the outer crushing tube 29 rotate in reverse. When it is necessary to adjust the crushing effect, the lifting push - pull cylinder 31 can be controlled to drive the outer crushing tube 29 to perform lifting operations. The transmission cylinder 26 is not only connected to the transmission rod 28 but also slidably and rotationally connected to the inner crushing shaft 25, ensuring that when the outer crushing tube 29 moves up and down, the transmission system is not affected and maintains a stable reverse rotational motion.

[0041] The crushed material is conveyed into the composting cavity 44 in the composting bin 10 through the feeding assembly connected to the bottom of the crushing bin 3. The feeding assembly includes a feeding screw 34 driven by the motor two 16.

[0042] The material in the composting cavity 44 is leveled, mixed, and turned over by the turning and mixing assembly 40 to promote oxygen contact and uniform distribution of microorganisms, accelerating the fermentation process. The horizontal drive assembly (including the lead screw 41, guide rod 42, and motor one 11) drives the turning and mixing assembly 40 to move horizontally to ensure full mixing of the composting material.

[0043] In addition, the blower 6 supplies air into the composting bin 10 through the air duct 9 and the filter 8 to maintain an appropriate oxygen concentration. As needed, the moisture content of the composting material can be adjusted through the water tank 13 and the water supply pipe 4, maintaining it between 45% - 65%. Excess water is periodically pumped out by controlling the water pump one 48 to maintain a good composting environment.

[0044] Through comparative tests, the crushing efficiency of this device is increased by 40% compared with traditional equipment, the composting cycle is shortened to 45 days, and the organic matter content of the finished organic fertilizer reaches 68%, meeting the NY525 - 2021 standard and being applicable to organic agriculture.

[0045] In summary, this integrated device for crushing and composting garden waste realizes efficient and uniform crushing of garden waste and reliable composting fermentation through the crushing assembly 32 that rotates in reverse and moves up and down and the turning and mixing assembly 40 that moves horizontally.
