Description

Technical Field

[0001] This invention relates to the field of environmental cleaning technology, and in particular to a waste sorting device and control method for landscaping. Background Technology

[0002] With social development, gardens and parks are gradually increasing across the country. Plant-based waste generated during garden and greening maintenance, plant cultivation, and urban greening management has obvious biomass characteristics and can usually be recycled through resource treatment. It is an important part of urban solid waste and mainly comes from branches, leaves, and grass clippings generated from the pruning of trees, shrubs, and lawns (such as thick branches from street trees and shredded leaves from hedges).

[0003] However, most garden waste usually contains metals and plastics. When sorting garden waste, staff need to separate the metals and plastics. This not only makes the sorting process slow and unable to meet the processing needs, but also makes it easy to come into contact with dangerous items such as sharp branches, rusted metals, and broken glass, which could cause personal injury.

[0004] Therefore, it is necessary to provide a waste sorting device and control method for landscaping to solve the above problems. Summary of the Invention

[0005] In view of the problems of the above-mentioned garden waste sorting device and control method, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a garden waste sorting device and control method, which can solve problems such as the inability to automatically sort garden waste.

[0007] In a first aspect, to solve the above-mentioned technical problems, the present invention provides the following technical solution: a garden greening waste sorting device, comprising: a frame, a conveyor roller, a first protective cover, a second protective cover, a separation mechanism, a first drive assembly, a screening mechanism, a segmentation mechanism, and a sorting mechanism.

The first drive motor and the first blower are provided on the first support frame, and the output shaft of the first drive motor is connected to the first blower.

[0011] In a preferred embodiment of the landscaping waste sorting device of the present invention, the segmentation mechanism includes a second roller, a second connecting plate, a chamfer, and a second drive assembly. The second roller is mounted on the second drive assembly. Multiple sets of the second connecting plates are fixedly connected to the outer surface of the second roller.

[0012] As a preferred embodiment of the garden greening waste sorting device of the present invention, a feeding platform is fixedly connected to one end of the frame near the first driving component, a discharging platform is connected to one end of the frame near the segmentation mechanism, and an inlet is provided on one end of the first protective cover near the feeding platform, and a discharging outlet is provided on one end of the first protective cover near the discharging platform.

[0013] As a preferred embodiment of the landscaping waste sorting device of the present invention, the sorting mechanism includes a crushing component and a sorting component. The crushing component includes a protective shell, a crushing drum, a third drive motor, and a mounting frame. The protective shell is disposed on the screening frame, the crushing drum is rotatably connected to the protective shell, and multiple sets of crushing drums are provided. The mounting frame is fixedly connected to the protective shell, and the third drive motor is fixedly connected to the mounting frame. The sorting component includes a second spring, a feeding plate, a semi-magnetic drum, a second mounting frame, a separating plate, and a second blower. One end of the second spring is disposed on the mounting frame, and the other end of the second spring is disposed on the feeding plate. The semi-magnetic drum is rotatably connected to the second mounting frame, the separating plate is fixedly connected to the second mounting frame, and the second blower is disposed on the second mounting frame.

[0014] Secondly, the present invention provides a control method for a landscaping waste sorting device, which includes the following steps:

[0015] S1: Place the garden waste on the discharge platform. The garden waste enters the conveyor roller through the feed inlet and moves forward through the first drive component.

[0016] S2: As the garden waste moves, when garden waste of different sizes passes through the first roller, the first rotating shaft slides on the third chute. As the first roller rotates, the first groove on the first connecting plate forces the garden waste to move and pushes it onto the separation mechanism.

[0017] S3: Garden waste slides on the conveyor rollers, and leaves and smaller branches fall through the gaps between the conveyor rollers onto the first filter screen on the screening rack. The leaves are filtered through the first filter screen, and the first drive motor drives the first blower to blow air. The airflow enters the screening rack through the second filter screen, and the leaves are blown out from the first opening with the airflow. Other garden waste falls out from the second opening under the influence of gravity.

[0018] S4: The remaining garden waste falls into the crushing drum through the second opening. The third drive motor drives the crushing drum to rotate. Multiple crushing drums crush the falling garden waste. The crushed garden waste falls from the protective shell into the feeding plate. The garden waste slides from the feeding plate. When the garden waste passes through the semi-magnetic drum, the ferromagnetic material is adsorbed on the surface of the semi-magnetic drum, while the non-metallic impurities fall vertically into one side of the distribution plate. As the semi-magnetic drum rotates, the ferromagnetic material is carried to the non-magnetic area. Under the influence of gravity or centrifugal force, it detaches from the surface of the semi-magnetic drum and falls from the other side of the distribution plate. At the same time, when the green waste falls from the feeding plate, the second blower blows air onto the falling green waste. Under the action of the wind, the lighter materials in the green waste are blown to a farther position.

[0019] S5: As the garden waste comes into contact with the first, second, and third scrapers, the first, second, and third scrapers separate the branches and leaves from the garden waste. When larger pieces of garden waste pass through the separation mechanism, the second and third scrapers move the first spring upwards via the telescopic rod, compressing the first spring and separating the branches and leaves from the garden waste. When garden waste of different sizes passes through the separation mechanism simultaneously, the first slider on the second scraper slides on the first groove, and the different second and third scrapers create height differences, separating garden waste of different sizes.

[0020] S6: The second drive motor drives the second roller to rotate on the second protective cover. The second connecting plate cuts the garden waste into segments of similar length, and the cut garden waste falls out of the second protective cover.

[0021] The beneficial effects of this invention are as follows: It enables the separation of metals, plastics, and branches and leaves from garden waste, allowing for more precise separation of different types of waste, improving the purity and quality of garden waste treatment, reducing the labor intensity of manual sorting, saving labor costs, and enabling the rapid processing of large quantities of waste, greatly increasing the speed of waste treatment. Furthermore, it avoids interference between the three types of materials. Metals and plastics are recyclable resources, and automatic separation allows for effective recycling, reducing resource waste. Separated branches and leaves can be used as organic fertilizer or biomass energy, while metals and plastics can be processed to reduce environmental pollution, improving the purity and quality of waste treatment. Additionally, automatic separation reduces the risk of worker injury, as manual sorting may involve contact with sharp metals. Attached Figure Description

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included. In the description of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for mutual communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0040] However, most garden waste usually contains metals and plastics. When sorting garden waste, staff need to separate the metals and plastics. This not only makes the sorting process slow and unable to meet the processing needs, but also makes it easy to come into contact with dangerous items such as sharp branches, rusted metals, and broken glass, which could cause personal injury.

[0041] Therefore, it is necessary to provide a waste sorting device and control method for landscaping to solve the above problems.

[0042] Example 1: Please refer to the following: Figures 1 to 12This invention provides a garden waste sorting device, comprising: a frame 100, a conveyor roller 101, a first protective cover 104, a second protective cover 108, a separation mechanism 200, a first drive assembly 300, a screening mechanism 400, a segmentation mechanism 500, and a sorting mechanism 600. The conveyor roller 101 is rotatably connected to the frame 100. The first protective cover 104 and the second protective cover 108 are both mounted on the frame 100. The separation mechanism 200 is mounted on the frame 100. The first driving component 300 is disposed on the first protective cover 104, the screening mechanism 400 is disposed on the frame 100, the segmenting mechanism 500 is disposed on the second protective cover 108, the sorting mechanism 600 is disposed on the screening mechanism 400, and the separation mechanism 200 is used to separate the raw materials. The first driving component 300 is used to drive the raw materials to move, the screening mechanism 400 is used to screen different raw materials, the segmenting mechanism 500 is used to segment the raw materials, and the sorting mechanism 600 is used to sort green waste.

[0043] Optionally, in some embodiments, please also refer to Figures 2 to 5 The first drive assembly 300 includes a first roller 301, a first connecting plate 302, a first rotating shaft 303, a third sliding groove 304, and a first groove 305. The first protective cover 104 has third sliding grooves 304 on both sides. The first rotating shaft 303 is slidably connected to the first protective cover 104 through the third sliding grooves 304. The first roller 301 is fixedly connected to the first rotating shaft 303. The first connecting plate 302 is fixedly connected to the outer surface of the first roller 301, and multiple sets of the first connecting plate 302 are provided. Multiple first grooves 305 are provided on the end of the first connecting plate 302 away from the first roller 301.

[0044] As can be seen from the above, when using a garden waste sorting device, the worker first needs to place the unsorted garden waste on the feeding platform 102. Then, the worker pushes the unsorted garden waste through the inlet 105 onto the conveyor roller 101. The conveyor roller 101 rotates on the frame 100, driving the unsorted garden waste forward. As the garden waste moves, the branches, after entering the inlet 105, come into contact with the first roller 301. As the first roller 301 rotates, the six first connecting plates 302 on the outer surface of the first roller 301 rotate with it. Because the first connecting plates 302 have multiple first grooves 305, the first grooves 305 can be embedded in the crevices or gaps on the surface of the branches. Through mechanical interlocking, the friction between the first roller 301 and the branches is increased, and the first grooves 305 can more firmly hold the branches in place. The first connecting plate 302 is designed to hold branches in place, preventing them from slipping on the conveyor roller 101 due to smooth surfaces or irregular shapes. This design is particularly suitable for damp branches or branches with sticky surfaces. It can force branches into the subsequent separation mechanism 200. Multiple sets of first connecting plates 302 are provided, with multiple first connecting plates 302 distributed circumferentially on the first roller 301 to ensure effective gripping in complex situations and improve conveying efficiency. The tip of the first groove 305 can insert into the branches or bends of the branches when the first roller 301 rotates, forcing the branches to adjust their posture along the conveying direction through rotational thrust. For example, it can straighten horizontally placed branches to vertical orientation, reducing the probability of branches tangling or getting stuck laterally. This design is particularly suitable for handling shrub branches with many branches. The sharp edge of the first groove 305 can cut or tear the leaves on the branches under the squeezing action of the first roller 301 and the conveyor roller 101, achieving a pre-crushing effect and initial separation of branches and leaves.

[0045] Optionally, in some embodiments, please also refer to Figures 2 to 12The screening mechanism 400 includes a screening frame 401, a blowing assembly 402, a first opening 403, a second opening 404, a third opening 405, and a second filter 406. The screening frame 401 is fixedly connected to the bottom surface of the frame 100. The first filter 103 is provided on the screening frame 401. The blowing assembly 402 is provided on the screening frame 401. The third opening 405 is opened on the side of the screening frame 401 closest to the blowing assembly 402, and the first opening 403 is opened on the side of the screening frame 401 furthest from the blowing assembly 402. The second opening 406 is located on the side of the screening frame 401 furthest from the frame 100. A second opening 404 is provided on one side of the screening rack 401. A second filter screen 406 is fixedly connected to the side of the screening rack 401 near the third opening 405. A blower assembly 402 is used to screen and classify garbage. The blower assembly 402 includes a first drive motor 4021, a first blower 4022 and a first support frame 4023. The first support frame 4023 is fixedly connected to one side of the screening rack 401. The first drive motor 4021 and the first blower 4022 are mounted on the first support frame 4023, and the output shaft of the first drive motor 4021 is connected to the first blower 4022.

[0046] As described above, as the garden waste moves forward under the drive of the conveyor roller 101 and the first roller 301, smaller branches and fallen leaves fall through the gaps between the conveyor rollers 101. During the falling process, leaves fall onto the first filter screen 103. After being filtered by the first filter screen 103, the leaves remain on the first filter screen 103. The remaining garden waste falls onto the screening rack 401 after passing through the first filter screen 103. The first drive motor 4021 drives the first blower 4022 to blow air. The airflow enters from the third opening 405 and exits from the first opening 403. An airflow channel is formed to separate falling green waste using airflow. Because leaves are light, they are blown up by the airflow and move with it, exiting through the first opening 403. The remaining green waste falls along the screening rack 401 and is discharged through the second opening 404. This separation relies on fluid mechanics and does not require the vibration and squeezing of traditional mechanical screening. It avoids hard friction with screens, scrapers and other components, greatly reducing equipment wear. There are no complex transmission parts, and only periodic cleaning of dust inside the air duct is required. The maintenance workload is far lower than that of mechanical separation equipment, improving work efficiency and preventing excessive breakage of leaves, thus maintaining their fiber integrity.

[0047] Optionally, in some embodiments, please also refer to Figure 6 and Figure 7The separation mechanism 200 includes a first fixed frame 201, a first scraper 202, a second scraper 203, a third scraper 204, an elastic component 205, and a second slide groove 206. The first fixed frame 201 is fixedly connected to the frame 100, and the second slide groove 206 is provided on the inner walls of both sides of the first fixed frame 201. The first scraper 202 is fixedly connected to the first fixed frame 201. The second scraper 203 and the third scraper 204 are both fixedly connected to the elastic component 205. The second scraper 203 has a first slider 2031 fixedly connected to both sides. The third scraper 204 has a first slide groove 2041 provided on both sides. Multiple sets of the second scraper 203 and the third scraper 204 are provided. The elastic component 205 is used to extend and retract the second scraper 203 and the third scraper 204.

[0048] The elastic component 205 includes a first spring 2051 and a telescopic rod 2052. The telescopic rod 2052 is fixedly connected to the first fixed frame 201. The end of the output shaft of the telescopic rod 2052 away from the first fixed frame 201 is fixedly connected to a second scraper 203 and a third scraper 204. The first spring 2051 is sleeved on the output shaft of the telescopic rod 2052.

[0049] As can be seen from the above, as a larger branch moves forward, one end of the branch will come into contact with the first scraper 202, multiple second scrapers 203, and the third scraper 204. As the branch continues to move, since the first scraper 202, second scraper 203, and third scraper 204 remain stationary, they will scrape the surface of the branch. Lighter, smaller parts of the branch that are not tightly connected to it will be scraped off and fall through the gap in the conveyor roller 101 along the first scraper 202. The branch continues to move forward under the drive of the first roller 301 and the conveyor roller 101 until all parts of the branch pass through the separation mechanism 200. When branches of different sizes are separated... When a large branch passes through the first scraper 202, second scraper 203, and third scraper 204, the scrapers 203 and 204 are compressed by the branch, causing the telescopic rod 2052 to move upward and compress the first spring 2051. Simultaneously, the first spring 2051 exerts a downward force on the scrapers 203 and 204, ensuring they are in close contact with the branch and scraping it until it completely passes through the separation mechanism 200. This way, when encountering a large branch, the scrapers are compressed upward, compressing the first spring 2051 to prevent excessive compression. When smaller branches pass through, the first spring 2052... 51 Reset allows the scraper to come close to the branch, ensuring thorough removal of leaves and improving separation efficiency. As the branch passes through with the conveyor roller 101, the second scraper 203 and the third scraper 204 are automatically pushed upwards by the branch, avoiding hard collisions and extending the equipment's lifespan. The elastic pressure of the first spring 2051 ensures that the cutting edges of the second scraper 203 and the third scraper 204 always remain in contact with the branch surface, guaranteeing separation quality. The automatic adjustment function of the first spring 2051 eliminates the need for frequent manual adjustments to the scraper height, reducing operational difficulty. Furthermore, when branches of different sizes pass through the first scraper 202, the second scraper 203, and the third scraper 204 simultaneously, the presence of multiple sets of second scrapers 203 and third scrapers 204 allows for the removal of larger branches. The first spring 2051 of the second scraper 203 and the third scraper 204 corresponding to the branches is compressed and lifted, while the scrapers that are not in contact remain in place. This prevents small leaves from being unable to be scraped off due to the overall lifting of a single set of scrapers, and accommodates the wide range of branch sizes. At the same time, as the second scraper 203 and the third scraper 204 move upward, the first slider 2031 set on both sides of the second scraper 203 slides in the first slide groove 2041, which limits the movement distance of the second scraper 203 and the third scraper 204, and precisely controls the movement range of the scrapers. This avoids equipment failure or reduced separation efficiency caused by excessive displacement, ensures synchronous movement of multiple sets of scrapers, improves the stability of separation efficiency, ensures that the scrapers work within the design range, and avoids equipment damage caused by overtravel.

[0050] Optionally, in some embodiments, please also refer to Figure 8 and Figure 9 The segmentation mechanism 500 includes a second roller 501, a second connecting plate 502, a chamfer 503, and a second drive assembly 504. The second roller 501 is mounted on the second drive assembly 504. Multiple sets of second connecting plates 502 are fixedly connected to the outer surface of the second roller 501, and a chamfer 503 is provided on the end of the second connecting plate 502 away from the second roller 501. The second drive assembly 504 is used to drive the second roller 501 to rotate.

[0051] The second drive assembly 504 includes a second drive motor 5041, a second rotating shaft 5042, and a second support frame 5043. The second support frame 5043 is fixedly connected to the second protective cover 108. The second drive motor 5041 is mounted on the second support frame 5043, and the output shaft of the second drive motor 5041 is connected to the second rotating shaft 5042. The second rotating shaft 5042 is rotatably connected to the second protective cover 108, and a second roller 501 is fixedly connected to the second rotating shaft 5042.

[0052] As can be seen from the above, as the branches move on the conveyor roller 101, after passing through the separation mechanism 200, the branches move to the discharge platform 107. As the second drive motor 5041 drives the second roller 501 to rotate, the second connecting plate 502 rotates with the rotation of the second roller 501. The end of the second connecting plate 502 away from the second roller 501 contacts the branches. Multiple sets of second connecting plates 502 cut the branches into segments, and at the same time, they cause the branches to fall from the second protective cover 108. In this way, branches of different lengths can be uniformly cut into branches of the same length, and the volume of the branches is reduced, making them easier to collect and store, improving the efficiency of separation and resource processing.

[0053] Optionally, in some embodiments, please also refer to Figure 4 A feeding platform 102 is fixedly connected to one end of the frame 100 near the first drive assembly 300, and a discharge platform 107 is connected to one end of the frame 100 near the segmentation mechanism 500. A feed inlet 105 is provided on one end of the first protective cover 104 near the feeding platform 102, and a discharge outlet 106 is provided on one end of the first protective cover 104 near the discharge platform 107.

[0054] Optionally, in some embodiments, please also refer to Figures 10 to 11The sorting mechanism 600 includes a crushing component 601 and a sorting component 602. The crushing component 601 includes a protective shell 6011, a crushing drum 6012, a third drive motor 6013, and a mounting frame 6014. The protective shell 6011 is mounted on the screening frame 401. The crushing drum 6012 is rotatably connected to the protective shell 6011, and multiple sets of crushing drums 6012 are provided. The mounting frame 6014 is fixedly connected to the protective shell 6011, and the third drive motor 6013 is fixedly connected to the mounting frame 6014. The sorting... Component 602 includes a second spring 6021, a feeding tray 6022, a semi-magnetic roller 6023, a second mounting bracket 6024, a distributing plate 6025, and a second blower 6026. One end of the second spring 6021 is disposed on the mounting bracket 6014, and the other end of the second spring 6021 is disposed on the feeding tray 6022. The semi-magnetic roller 6023 is rotatably connected to the second mounting bracket 6024. The distributing plate 6025 is fixedly connected to the second mounting bracket 6024. The second blower 6026 is disposed on the second mounting bracket 6024.

[0055] As described above, the remaining landscaping waste falls from the first filter screen 103 into the screening rack 401, and then from the second opening 404 in the screening rack 401 into the protective shell 6011. The third drive motor 6013 is then activated, driving the two crushing rollers 6012 to rotate within the protective shell 6011. As the two crushing rollers 6012 rotate, the landscaping waste is crushed into fragments and falls from the protective shell 6011 onto the feeding disc 6022. Vibration causes the green waste to be fed evenly. As the green waste falls, it passes through the semi-magnetic roller 6023. Metal substances in the green waste are attracted to the semi-magnetic roller 6023. At the same time, the second blower 6026 is activated, generating airflow to separate the falling green waste. Lighter materials such as plastics and films in the green waste are blown away by the airflow to a farther location, while broken branches, due to their greater weight, fall closer and drop from one side of the separating plate 6025. By collecting materials from different landing points... To achieve separation, as the semi-magnetic roller 6023 rotates, the magnetic material adsorbed on it is driven to the non-magnetic or weakly magnetic areas. Under the action of gravity or centrifugal force, the magnetic material on the surface of the semi-magnetic roller 6023 detaches from it and slides off the other side of the separating plate 6025. This allows for the separation of metals, plastics, and branches and leaves from garden waste, enabling more precise separation of different types of waste, improving the purity and quality of garden waste treatment, reducing the labor intensity of manual sorting, saving labor costs, and quickly processing large amounts of waste, greatly increasing the speed of waste treatment. It also avoids interference between the three types of materials. Metals and plastics are recyclable resources, and automatic separation can effectively recycle them, reducing resource waste. Separated branches and leaves can be used as organic fertilizer or biomass energy, while metals and plastics can be processed to reduce environmental pollution, improving the purity and quality of waste treatment. Furthermore, manual sorting may involve contact with sharp metals, and automatic separation can reduce the risk of worker injury.

[0056] Example 2: This application also provides a control method for a landscaping waste sorting device. The control method for a landscaping waste sorting device includes the following steps:

[0057] S1: Place the garden waste on the discharge platform 107. The garden waste enters the conveyor roller 101 through the feed port 105 and moves forward through the first drive component 300.

[0058] S2: As the garden waste moves, when garden waste of different sizes passes through the first roller 301, the first rotating shaft 303 slides on the third sliding groove 304. As the first roller 301 rotates, the first groove 305 on the first connecting plate 302 forces the garden waste to move and pushes the garden waste onto the separation mechanism 200.

[0059] S3: Garden waste slides on the conveyor roller 101. Leaves and smaller branches fall through the gaps between the conveyor rollers 101 onto the first filter screen 103 on the screening rack 401. Leaves are filtered on the first filter screen 103. The first drive motor 4021 drives the first blower 4022 to blow air. The airflow enters the screening rack 401 through the second filter screen 406. Leaves are blown out from the first opening 403 by the airflow, while other garden waste falls from the second opening 404 under the influence of gravity.

[0060] S4: The remaining garden waste falls from the second opening 404 into the crushing drum 6012. The third drive motor 6013 drives the crushing drum 6012 to rotate. Multiple sets of crushing drums 6012 crush the falling garden waste. The crushed garden waste falls from the protective shell 6011 into the feeding plate 6022. The garden waste slides down from the feeding plate 6022. When the garden waste passes through the semi-magnetic drum 6023, the ferromagnetic material in it is attracted to the semi-magnetic drum 6023. 23. Non-metallic impurities fall vertically onto one side of the distribution plate 6025. As the semi-magnetic roller 6023 rotates, ferromagnetic materials are carried to the non-magnetic area. Under the influence of gravity or centrifugal force, they detach from the surface of the semi-magnetic roller 6023 and fall from the other side of the distribution plate 6025. At the same time, when the green waste falls from the feeding tray 6022, the second blower 6026 blows the falling green waste. Under the action of the wind, the lighter materials in the green waste are blown to a farther position.

[0061] S5: As the garden waste comes into contact with the first scraper 202, the second scraper 203, and the third scraper 204, the first scraper 202, the second scraper 203, and the third scraper 204 separate the branches and leaves on the garden waste. When larger garden waste passes through the separation mechanism 200, the second scraper 203 and the third scraper 204 move the first spring 2051 upward through the telescopic rod 2052, compressing the first spring 2051 and separating the branches and leaves on the garden waste. When garden waste of different sizes passes through the separation mechanism 200 at the same time, the first slider 2031 on the second scraper 203 slides on the first slide groove 2041. Different second scrapers 203 and third scrapers 204 form height differences, separating garden waste of different sizes.

[0062] S6: The second drive motor 5041 drives the second roller 501 to rotate on the second protective cover 108. The second connecting plate 502 cuts the garden waste into segments of similar length, and the cut garden waste falls out of the second protective cover 108.
