Description

Technical Field

[0001] The invention relates to the technical field of garden waste recycling, in particular to a garden waste crushing and recycling device. Background Art

[0002] Garden waste refers to various wastes generated in the process of landscaping, including trimmed branches, leaves, lawn clippings, dead branches and leaves, and flower remains. These wastes are continuously generated in the process of garden maintenance and the quantity is huge. Traditional treatment methods such as landfill and incineration not only occupy land resources, but also produce secondary pollution. Therefore, it is particularly important to find an efficient and environmentally friendly way to treat garden waste. In order to solve the problem of garden waste treatment, crushing and reuse technology has come into being. This technology crushes garden waste and converts it into small particles or debris to facilitate the subsequent composting fermentation and reuse process. Crushing is the first step in the reuse of garden waste. The waste is crushed into particles of appropriate size by an efficient crusher. The crushed garden waste can be used as compost raw material and converted into organic fertilizer through the fermentation of microorganisms. This fertilizer is rich in nutrients and can improve soil structure and increase the yield and quality of crops.

[0003] Prior art CN220788425U discloses a composting device for treating garden greening organic waste, which includes a box body, two third support plates fixedly connected to the inside of the box body, the tops of the two third support plates are fixedly connected to a first limit plate, a compost box is slidably connected to the inside of the first limit plate, and a vibration component for vibrating the compost box up and down is provided at the bottom of the compost box. The device achieves the effect of vibrating the garden greening organic waste in the compost box by moving the compost box up and down under the restriction of the two first limit plates, so that the inside of the garden greening organic waste can be fully exposed to oxygen, but the compost material is usually composed of various These organic matter will form different densities and structures during the composting process. If the compost density is too high or the structure is tight, vibration cannot effectively penetrate the entire compost layer, resulting in difficulty for oxygen to reach the deep layer of the material. Moreover, not all types of landscaping organic waste are suitable for vibration. For example, waste that is too wet or sticky makes it difficult for oxygen to penetrate, because water will fill the pores and reduce air circulation. The difficulty of oxygen penetration will lead to the weakening of microbial degradation, causing the composting process to become slow, thereby prolonging the composting cycle. The difficulty of oxygen penetration will also make the compost unable to be completely decomposed, resulting in low quality of the compost product.

[0004] Therefore, the present invention proposes a device for recycling garden waste after crushing to improve the shortcomings of traditional technology. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a device for crushing and recycling garden waste, which solves the problems raised in the above background technology.

[0010] Preferably, the auxiliary component also includes a cylindrical column, which is rotatably connected to the interior of the auxiliary shell, and the interior of the cylindrical column is slidably connected to a second cylinder, and the outer surface of the second cylinder is provided with a square groove, and the interior of the square groove is slidably connected to a square plate.

[0011] Preferably, the auxiliary component also includes a first gear, the outer surface of the first gear is fixedly connected to the first cylinder, the bottom of the first gear is meshed with the second gear, the inner side of the second gear is fixedly connected to the outer surface of the cylindrical column, the end of the second cylinder close to the second gear is highly connected to the third gear, the bottom of the third gear is meshed with the fourth gear, the side of the fourth gear away from the second gear is rotatably connected to the outer surface of the movable plate, and the inner side of the fourth gear is fixedly connected to the outer surface of the spiral column.

[0015] 1. Through the coordinated use of the first, third and fourth gears, the spiral column rotates in the compost raw materials.

[0016] 2. By using the rotating main shaft, rotating circular plate and spiral column in coordination, the spiral column is driven to rotate around the rotating main shaft during its self-rotation. The combination of the self-rotation and revolution of the spiral column can more effectively stir the compost raw materials and make them more uniform. This stirring method can ensure that all parts of the compost raw materials can be fully mixed and turned, thereby improving the stirring efficiency, which helps to optimize the distribution of oxygen in the compost raw materials and provide a better growth environment for microorganisms. Stirring can break up the agglomerates in the compost raw materials, making them looser, and improving the efficiency and diversity of microbial activity. By using the threaded column, spiral column, half gear and full gear in coordination, the spiral column can move intermittently during its rotation around the rotating main shaft, so that the diameter area of ​​the spiral column rotating around the rotating main shaft gradually increases, which can stir all the compost raw materials in the device shell, bring the raw materials inside the compost into contact with the air, and ensure that the compost raw materials in the device shell are fully stirred.

[0028] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] refer to Figures 1 to 8 As shown, a preferred embodiment of the present invention will be described in detail below:

[0030] A device for recycling crushed garden waste includes a device shell 1, the bottom of the device shell 1 is fixedly connected to a discharge pipe 2, the top of the device shell 1 is penetrated by a rotating main shaft 3 and is rotatably connected, the top of the rotating main shaft 3 is fixedly connected to a motor, one end of the rotating main shaft 3 located in the device shell 1 is fixedly connected to a rotating circular plate 4, and the bottom of the rotating circular plate 4 is provided with an auxiliary component 5 for improving the quality of compost products. Through the coordinated use of the rotating main shaft 3, the rotating circular plate 4 and the spiral column 55, the spiral column 55 is driven to rotate around the rotating main shaft 3 during the process of its self-rotation. The combination of the self-rotation and revolution of the spiral column 55 can more effectively stir the compost raw materials and make them more uniform. This stirring method can ensure that all parts of the compost raw materials can be fully mixed and turned, thereby improving the stirring efficiency, which helps to optimize the distribution of oxygen in the compost raw materials and provide a better growth environment for microorganisms. The stirring can break up the agglomerates in the compost raw materials, make them looser, and improve the efficiency and diversity of microbial activity.

[0031] The auxiliary component 5 includes an auxiliary shell 51, which is fixedly mounted on the bottom of the rotating circular plate 4. The inner wall of the auxiliary shell 51 is fixedly connected to the limit shell 52. The inner wall of the limit shell 52 is rotatably connected to a threaded column 53. The threaded column 53 penetrates and is rotatably connected to the inner part of the auxiliary shell 51. The outer surface of the threaded column 53 is threadedly connected to a movable plate 54. The bottom of the movable plate 54 is rotatably connected to a spiral column 55. The auxiliary component 5 also includes a driving device 56, the outer surface of which is fixedly connected to a first cylinder 57. The first cylinder 57 penetrates and is rotatably connected to the inner part of the auxiliary shell 51. The end of the first cylinder 57 away from the driving device 56 is fixedly connected to a semi-toothed The outer surface of the wheel 58 and the half gear 58 are meshedly connected with the full gear 59, the threaded column 53 slides inside the limiting shell 52, and the outer surface of the full gear 59 is fixedly connected to the end of the threaded column 53 located outside the auxiliary shell 51. Through the coordinated use of the threaded column 53, the spiral column 55, the half gear 58 and the full gear 59, the spiral column 55 is intermittently moved during the rotation around the rotating main shaft 3, so that the diameter area of ​​the spiral column 55 rotating around the rotating main shaft 3 gradually becomes larger, which can stir all the compost materials in the device shell 1, and make the materials inside the compost contact with the air, ensuring that the compost materials in the device shell 1 are fully stirred.

[0032] The auxiliary component 5 also includes a cylindrical column 512, which is rotatably connected to the interior of the auxiliary shell 51, and the interior of the cylindrical column 512 is slidably connected to the second cylinder 513. The outer surface of the second cylinder 513 is provided with a square slide groove 514, and the interior of the square slide groove 514 is slidably connected to a square plate 515. The size of the square slide groove 514 is adapted to the size of the square plate 515. The outer surface of the square plate 515 is fixedly connected to the inner wall of the cylindrical column 512, and the square plate 515 slides inside the square slide groove 514. In this way, the square plate 515 restricts the second cylinder 513, and the rotation of the square plate 515 will drive the second cylinder 513 to rotate, and the second cylinder 513 can also slide left and right during the rotation process. This design is to ensure that the third gear 516 always keeps meshing with the fourth gear 517, so that when the spiral column 55 moves, the meshing of the fourth gear 517 and the third gear 516 enables it to still rotate, turning over and stirring the internal raw materials of the compost, which helps to ensure that all parts of the waste can fully contact with oxygen.

[0033] The outer surface of the first cylinder 57 is fixedly connected to the first gear 510, and the bottom of the first gear 510 is meshed with the second gear 511. The inner side of the second gear 511 is fixedly connected to the outer surface of the cylindrical column 512, and the end of the second cylinder 513 close to the second gear 511 is highly connected to the third gear 516. The bottom of the third gear 516 is meshed with the fourth gear 517. The side of the fourth gear 517 away from the second gear 511 is rotatably connected to the outer surface of the movable plate 54, and the inner side of the fourth gear 517 is fixedly connected to the outer surface of the spiral column 55. The spiral column 55 is driven by the transmission of the gear to rotate during the rotation process. In this way, the raw materials inside the compost are in contact with the external air, thereby obtaining the necessary oxygen, which is beneficial to converting organic matter into stable humus and making the decomposition more efficient, which helps to shorten the composting cycle and improve production efficiency.

[0034] An air supply pipe 518 is fixedly connected to the interior of the spiral column 55, and the air supply pipe 518 passes through the interior of the movable plate 54 and the auxiliary shell 51. An air outlet hole 519 is opened on the outer surface of the spiral column 55, and the air outlet hole 519 is connected to the air supply pipe 518. The air outlet holes 519 are distributed in an array along the outer surface of the spiral column 55. The air outlet holes 519 are distributed in an array on the outer surface of the spiral column 55, which helps to ensure that different heights of the composting raw materials can obtain sufficient oxygen supply, thereby improving the uniformity of oxygen distribution during the composting process.

[0035] Compared with the prior art, the device sends the compost raw materials at the bottom of the device shell 1 out of the raw materials through the spiral rotation of the spiral column 55, so that the raw materials inside the compost are in contact with the external air, thereby obtaining the necessary oxygen, which is beneficial to converting organic matter into stable humus. During the rotation of the spiral column 55, oxygen can also be sent into the compost raw materials, ensuring that different heights of the compost raw materials can obtain sufficient oxygen supply, thereby improving the uniformity of oxygen distribution during the composting process. By stirring, the compost raw materials at the bottom are turned upwards, and at the same time, the gas flows from the inside of the spiral column 55 to the inside of the fertilizer. This method can more directly introduce oxygen into the interior of the fertilizer, thereby improving the efficiency and effect of oxygen contact. Compared with the vibration method, the stirring plus gas injection method does not require continuous vibration energy consumption, and the noise generated during the stirring process is relatively small. The stirring method is more suitable for various types of waste, including wet or sticky waste, because stirring can more effectively break up the agglomeration of these wastes.

[0036] The following is the entire working process and working principle of the above embodiment:

[0037] First, the operator puts the crushed garden waste into the interior of the device shell 1 for fermentation. In order to improve the uniform decomposition of the waste, it is necessary to keep the inside of the compost waste in contact with oxygen, so as to ensure the uniform fermentation of the waste. The operator starts the motor and the driving device 56 at the same time. The driving device 56 rotates to drive the first cylinder 57 to rotate. The rotation of the first cylinder 57 drives the first gear 510 to rotate. The rotation of the first gear 510 drives the second gear 511 engaged therewith to rotate. The rotation of the second gear 511 drives the cylindrical column 512 to rotate. The rotation of the cylindrical column 512 drives the square plate 515 to rotate. The rotation of the square plate 515 drives the second cylinder 513 to rotate. The rotation of the second cylinder 513 drives the third gear 516 to rotate. The rotation of the third gear 516 drives the fourth gear 517 to rotate. The rotation of the fourth gear 517 drives the spiral column 55 to rotate. The spiral column 55 rotates in the compost raw materials. The spiral column 55 is in The compost raw materials rotate in the compost, and the compost raw materials at the bottom of the device shell 1 are sent out of the raw materials through the spiral rotation of the spiral column 55, so that the raw materials inside the compost are in contact with the external air, thereby obtaining the necessary oxygen, which is beneficial to converting organic matter into stable humus and making the decomposition more efficient. This helps to shorten the composting cycle and improve production efficiency. During the rotation of the spiral column 55, the moisture and heat inside the compost raw materials are released, which helps to regulate the temperature and humidity of the compost, accelerate the composting process and improve product quality. By supplying air to the inside of the air supply pipe 518, the gas flows out from the air outlet 519, so that the spiral column 55 can deliver oxygen into the compost raw materials during the rotation process, which is suitable for moist compost raw materials. The air outlet holes 519 are distributed on the outer surface of the spiral column 55 in an array, which helps to ensure that different heights of the compost raw materials can obtain sufficient oxygen supply, thereby improving the uniformity of oxygen distribution during the composting process.

[0038] At the same time, the motor drives the rotating main shaft 3 to rotate, and the rotation of the rotating main shaft 3 drives the rotating circular plate 4 to rotate. The rotation of the rotating circular plate 4 drives the auxiliary shell 51 and the spiral column 55 to rotate. The rotation of the spiral column 55 drives the spiral column 55 to rotate around the rotating main shaft 3 during the rotation of the spiral column 55. The combination of the rotation and revolution of the spiral column 55 can more effectively stir the compost raw materials and make them more uniform. This stirring method can ensure that all parts of the compost raw materials can be fully mixed and turned, thereby improving the stirring efficiency, which helps to optimize the distribution of oxygen in the compost raw materials and provide a better growth environment for microorganisms. Stirring can break up the agglomerates in the compost raw materials, make them looser, and improve the efficiency and diversity of microbial activities.

[0039] At the same time, the driving device 56 rotates to drive the first cylinder 57 to rotate, and the rotation of the first cylinder 57 drives the half gear 58 to rotate. The half gear 58 rotates one circle and drives the full gear 59 to rotate half a circle. The rotation of the full gear 59 drives the threaded column 53 to rotate. The threaded column 53 rotates and drives the movable plate 54 threadedly connected to it to move inside the limiting shell 52. The movement of the movable plate 54 drives the spiral column 55 to move horizontally. The spiral column 55 moves horizontally and drives the third gear 516 to move. The third gear 516 drives the second cylinder 513 to move inside the cylindrical column 512. Through the coordinated use of the threaded column 53, the spiral column 55, the half gear 58 and the full gear 59, the spiral column 55 is intermittently moved during the rotation around the rotating main shaft 3, so that the diameter area of ​​the spiral column 55 rotating around the rotating main shaft 3 gradually increases, which can stir all the compost materials in the device housing 1, and bring the materials inside the compost into contact with air, ensuring that the compost materials in the device housing 1 are fully stirred.
