[0002] Garden dead leaves are natural waste generated during the landscaping process. They are mainly composed of the leaves of deciduous trees, shrubs and other plants. As an important part of garden waste, if not handled properly, dead leaves will not only affect the garden landscape, but may also cause environmental pollution and waste of resources. At present, the treatment of garden dead leaves is mainly through the collection, crushing, transformation and resource reuse of dead leaves.
[0003] Currently, when collecting thick layers of fallen leaves, gardeners typically use rakes to gather the leaves into piles, then pack them into woven bags or plastic sheets for transport to the treatment site, which is inefficient. Existing leaf collectors absorb the fallen leaves into a treatment box and then crush them, but in rainy weather, the leaves at the bottom layer tend to stick together tightly to the ground after being soaked by rainwater, making it difficult to extract and collect them smoothly. This requires gardeners to clean them manually, increasing their workload. Utility Model Content

[0019] This embodiment describes a garden leaf removal device, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a mobile cart 1, a processing box 5 mounted on the frame of the mobile cart 1, and the bottom of the processing box 5 connected to the mobile cart 1 via several support plates 3. A vacuum pump 9 is installed on the top of the processing box 5 to create a vacuum inside the processing box 5. A collection frame 2 is detachably connected to the discharge port at the bottom of the processing box 5. A fixed cover 11 is mounted on the mobile cart 1 on one side of the processing box 5. A roller 13 is mounted at the opening of the fixed cover 11. Several stirring blades 12 for sweeping the dead leaves are mounted on the roller 13. A first motor 14 for driving the roller 13 to rotate is mounted on the side wall of the fixed cover 11. The fixed cover 11 and the processing box 5 are connected and communicated through a conveying pipe 10.
[0020] The mobile cart 1 includes a frame with wheels mounted on the bottom to support and move the cart, ensuring stability and flexibility on different terrains. A handle is fixed to one side of the frame for operating and pushing the cart. It also includes a braking system for controlling the cart's deceleration and stopping, a steering wheel and steering gear for controlling the cart's direction of travel, and an electric motor, fuses, contactors, etc., for controlling the cart's power and operation. The mobile cart 1 is used to collect and process fallen leaves on the ground. The mobile cart 1 is existing technology, and its specific structure and operating principle will not be elaborated here.
[0021] A processing box 5 is installed on the frame of the mobile cart 1. Several support plates 3 are welded or glued to the bottom of the processing box 5. The support plates 3 are welded or glued to the top of the frame of the mobile cart 1. A vacuum pump 9 is installed on the top of the processing box 5. An air guide pipe is provided at the suction end of the vacuum pump 9. A fixing hole is opened on the top of the processing box 5. The air guide pipe passes through the fixing hole and is connected to the processing box 5. The vacuum pump 9 creates a negative pressure state inside the processing box 5, thereby adsorbing the dead leaves. A collection frame 2 is connected to the discharge port at the bottom of the processing box 5 through a threaded pipe. A threaded pipe is fixed on the top of the collection frame 2. An external thread that is threaded to the threaded pipe is opened at the discharge port at the bottom of the processing box 5. The collection frame 2 is installed at the discharge port of the processing box 5.
[0022] A fixed cover 11 is installed on the top of the frame of the mobile cart 1 on one side of the processing box 5. The opening of the fixed cover 11 faces downward. A first motor 14 is installed on the side wall of the opening of the fixed cover 11. A mounting hole is opened on the side wall of the fixed cover 11 corresponding to the output shaft of the first motor 14. After the output shaft extends into the mounting hole, it is connected to the roller 13. The other end of the roller 13 is rotatably connected to the inner wall of the fixed cover 11 through a bearing. Several stirring blades 12 are provided on the roller 13. The output shaft of the first motor 14 drives the roller 13 to rotate, and the roller 13 drives the several stirring blades 12 to stir the dead leaves. The blades sweep and agitate the leaves inside the fixed cover 11, allowing the dead leaves to be directly fed into the fixed cover 11. The agitator blades 12 can also quickly peel off and collect the dead leaves adhering to the ground, improving the efficiency of dead leaf collection and processing, and reducing the time and labor intensity of manual sweeping. The fixed cover 11 and the processing box 5 are both provided with mounting holes on their side walls. The two ends of the conveying pipe 10 are fixed in the mounting holes respectively. The fixed cover 11 and the processing box 5 are connected through the conveying pipe 10, so that the dead leaves swept into the fixed cover 11 are adsorbed into the processing box 5 through the conveying pipe 10 for collection and processing.
[0023] In actual use, the mobile cart 1 is moved to the location of the dead leaves, the vacuum pump 9 is started to create a negative pressure state inside the processing box 5, and the first motor 14 is started so that its output shaft drives the roller 13 to rotate. The roller 13 drives several stirring blades 12 to rotate. The stirring blades 12 sweep the dead leaves and stir them towards the inside of the fixed cover 11. The dead leaves in the fixed cover 11 are adsorbed into the processing box 5 through the conveying pipe 10. The dead leaves enter the collection frame 2 for collection. This can collect and process the dead leaves that are stuck to the ground, improve the efficiency of dead leaf processing, and reduce the time and labor intensity of manual cleaning.
[0024] This embodiment further illustrates the technology. A second motor 8 is installed on the top of the processing box 5. A rotating rod that passes through the processing box 5 is fixed to the output end of the second motor 8. Several blades 7 for crushing dead leaves are provided on the rotating rod. The processing box 5 has a through hole at the top. The output shaft of the second motor 8 is fixed to the rotating rod that extends into the processing box 5 after entering the through hole. Several blades 7 are provided on the rotating rod. When the second motor 8 is started, its output shaft drives the rotating rod to rotate. The rotation of the rotating rod drives the several blades 7 to crush the dead leaves entering the processing box 5. The high-speed rotating blades 7 can quickly crush the dead leaves into small particles. The volume of the crushed dead leaves is reduced, which is convenient for subsequent collection, transportation and reuse, and reduces processing costs. The crushed dead leaves can be used as organic fertilizer or compost raw materials to increase the organic matter content of the soil, improve soil structure, and promote resource recycling. The volume of the crushed dead leaves is greatly reduced, saving storage space and facilitating centralized management and processing.
[0025] A filter screen 6 is installed inside the processing box 5. The filter screen 6 is attached to the inner wall of the processing box 5 and blocks the dead leaves. When the dead leaf residue is broken into small particles, it can pass through the filter holes of the filter screen 6 and enter the collection frame 2. The broken dead leaves are collected by the collection frame 2 and then removed from the processing box 5. The broken dead leaves are then dumped in a unified manner for further processing so that they can be reused later.
[0026] This embodiment further explains the technology. Limiting plates 15 are provided on both the front and rear sides of the fixed cover 11. Threaded holes are provided on the limiting plates 15, and screws 16 are threaded into these holes. The tightening end of the screw 16 abuts against the side wall of the fixed cover 11. Limiting plates 15, fixed to the top of the frame of the mobile platform 1, are welded or glued to both the front and rear sides of the fixed cover 11. Screws 16 are threaded into the threaded holes on the limiting plates 15, and the tightening end of the screw 16 abuts against the side wall of the fixed cover 11. This allows the fixed cover 11 to adjust its height between the two limiting plates 15, thereby adjusting... The height of the blades 7 at the opening of the fixed cover 11 can be adjusted to more accurately contact and peel off dead leaves adhering to the ground, ensuring more thorough removal and collection of dead leaves, avoiding omissions, and ensuring a cleaner and more thorough cleaning effect. This significantly improves cleaning efficiency and reduces manual operation time and labor intensity. The adjustable height of the blades 7 allows them to adapt to different terrains and ground conditions, ensuring effective cleaning of dead leaves in various environments. Reasonable adjustment of the blade height can avoid excessive contact with the ground, reduce damage to the ground, and protect the integrity of the ground surface.
[0027] The front and rear walls of the fixed cover 11 are provided with sliding grooves, and each groove is provided with a slider that slides and is fixed to the side wall of the limiting plate 15. The slider has a through hole for the screw 16 to pass through. The sliding grooves on the front and rear inner walls of the fixed cover 11 are provided with sliders that slide and are fixed to the limiting plate 15. The through holes on the sliders are for the screw 16 to pass through. The sliding cooperation between the grooves and the sliders makes the fixed cover 11 move more smoothly and stably between the two limiting plates 15, ensuring the stability of the fixed cover 11 and the blade 7. Tighten the screw 16 to make it threaded into the threaded hole. After the screw 16 passes through the through hole of the slider, it presses against the inner wall of the groove to fix the position of the fixed cover 11. Loosen the screw 16 to release the pressure on the inner wall of the groove, and the height of the blade 7 can be adjusted again to better collect the dead leaves on the ground. The corresponding conveying pipe 10 is a telescopic hose so that it can extend and retract with the up and down movement of the fixed cover 11 without affecting the conveying of dead leaves into the processing box 5.
[0028] This embodiment further explains the technology. The top of the collection box 2 is provided with a limiting band, and the bottom of the processing box 5 is provided with a card slot with an annular structure. A limiting ring 4 is provided in the card slot to embed the limiting band and to engage with the card slot.
[0029] A limiting strip is attached to the top of the collection box 2, and an annular groove is provided at the bottom of the processing box 5. The limiting strip passes through the center of the limiting ring 4 and covers the top of the limiting ring 4. Then the limiting ring 4 is embedded in the groove, and the limiting strip is pressed into the groove. The collection box 2 is installed at the discharge port of the processing box 5. When the collection box 2 is full of dead leaves, the limiting ring 4 is removed from the groove, and then the limiting strip is removed from the groove. The dead leaves in the collection box 2 are then uniformly processed to make them more reusable.
[0030] This embodiment further illustrates the technology. The bottom of the processing box 5 has a funnel-shaped structure. The funnel shape at the bottom of the processing box 5 allows the dead leaves to enter the collection frame 2 more effectively for collection and processing. Cleaning up the dead leaves helps to maintain the cleanliness and beauty of the garden landscape and improve the overall environmental quality. The dead leaves can be used as organic fertilizer, feed or compost raw materials. After fermentation, they can provide nutrients for plants and realize resource recycling.
