Abstract
Description
Technical Field
[0001] This application relates to the technical field of gardening, and in particular to a garden leaf collection device. Background Technology
[0002] In garden maintenance, leaf collection is a crucial step. Current methods primarily involve using an air pump to blow air into the leaves one by one, gathering them in one spot before collecting and cleaning them. This method is relatively inefficient and requires workers to constantly hold the air pump, changing direction to blow air into the fallen leaves, which is labor-intensive, especially when dealing with large quantities of leaves. Furthermore, improper airflow control can cause leaves to scatter, increasing the difficulty of cleanup. Summary of the Invention
[0003] To improve the efficiency of collecting garden leaves, this application provides a garden leaf collecting device.
[0004] This application provides a garden leaf collection device, which adopts the following technical solution: A garden leaf collection device includes a collection box, a leaf suction pipe, an extrusion component, and a walking mechanism. The top of the collection box is open to form a collection cavity. The leaf suction pipe is disposed on the wall of the collection box. The wall of the collection box has a communication port for connecting the collection cavity and the leaf suction pipe. The leaf suction pipe has a power component for feeding leaves from the leaf suction pipe into the collection cavity. The extruder moves up and down in the collection box, and the collection box has a moving part for driving the extruder to move up and down, so that the extruder squeezes the leaves in the collection chamber when it moves down; the walking mechanism is installed at the bottom of the collection box and is used to drive the collection box to move.
[0005] By adopting the above technical solution, the power component provides power so that the collection box can automatically suck leaves into the collection box through the leaf suction pipe when it moves, thereby completing the collection of leaves while the collection box is moving, improving the efficiency of collecting garden leaves and reducing labor intensity. In addition, the squeezing component moves up and down in the collection cylinder to squeeze the leaves in the collection chamber, making the leaves stacked more tightly together, reducing the looseness of the leaves, increasing the storage capacity of the collection box, and further improving the efficiency of leaf collection.
[0006] Optionally, the extrusion member includes a moving rod and a pressure plate. The moving rod extends vertically and cooperates with the moving member. The pressure plate is disposed on the moving rod, and the cross-sectional dimension of the pressure plate is adapted to the cross-sectional dimension of the collection box at the collection cavity. The leaf suction pipe is equipped with an opening and closing member for opening and closing the end of the leaf suction pipe near the collection box. When the pressure plate is higher than the connecting port, the opening and closing member opens the leaf suction pipe. When the pressure plate is opposite to or lower than the connecting port, the opening and closing member closes the leaf suction pipe.
[0007] By adopting the above technical solution, the opening and closing of the leaf suction pipe by the opening and closing component makes it difficult for the leaves to enter the collection box from the leaf suction pipe and fall onto the upper surface of the pressure plate when the pressure plate compresses the leaves downwards. This makes it less likely for the leaves to be carried out of the collection box by the pressure plate, thus improving the stability of leaf collection.
[0008] Optionally, the pressure plate slides up and down on the moving rod, and a limiting plate is provided on the moving rod above the pressure plate. A first elastic element is connected between the limiting plate and the pressure plate. The first elastic element is used to lift the pressure plate and provide resistance to the pressure plate moving towards the limiting plate. The limiting plate moves up and down on the moving rod, and a linkage box that can slide up and down on the moving rod is provided between the limiting plate and the pressure plate. The linkage box is connected to the limiting plate. A positioning rod is vertically arranged inside the movable rod. The positioning rod has multiple slots along its own height direction. The movable rod has a long groove that connects the positioning rod and the external space of the movable rod. The long groove extends along the height direction of the movable rod. The linkage box has a portion that extends into the long groove. The linkage box has a plug rod that slides along the length direction perpendicular to the positioning rod for insertion into the slot. The linkage box has a linkage component that cooperates with the plug rod. When the pressure plate moves against the resistance of the first elastic element to abut against the linkage box, the linkage component drives the plug rod to disengage from the positioning rod. When the pressure plate is driven away from the linkage box by the first elastic element, the linkage component drives the plug rod to insert into the positioning rod.
[0009] By adopting the above technical solution, as the leaves gradually accumulate, the pressure plate will be pushed upward by the leaves during its downward movement, causing the pressure plate to resist the elastic force of the first elastic element and move upward. Through the contact and cooperation between the pressure plate and the linkage box, the linkage component is driven to move, so that the insertion rod can disengage from the locked position with the positioning rod, and the linkage box and the limit plate can move upward by the elastic force of the first elastic element. After the linkage box and the pressure plate are disengaged, the insertion rod is re-locked with the positioning rod, so that the position of the linkage box and the limit plate is adjusted according to the thickness of the compressed leaves, so that the pressure plate is not prone to excessive downward movement.
[0010] Optionally, the linkage assembly includes a locking rod, a protruding post, and a second elastic element. The locking rod slides up and down on the linkage box. The protruding post is disposed on the locking rod. The insert rod has a linkage groove for the protruding post to abut and slide. The linkage groove is inclined upward along the direction close to the positioning rod. The second elastic element is disposed in the linkage box and cooperates with the locking rod to drive the locking rod to move out of the linkage box towards the pressure plate. At this time, the insert rod is inserted into the positioning rod. When the pressure plate presses the locking rod upward into the linkage box, the locking rod guides the insert rod to disengage from the positioning rod through the protruding post.
[0011] By adopting the above technical solution, the locking rod cooperates with the insert rod through the protrusion, so that when the locking rod is pushed by the pressure plate, it drives the insert rod to move away from the positioning rod. Furthermore, through the cooperation of the second elastic element with the locking rod, the insert rod can be reset when the locking rod leaves the pressure plate.
[0012] Optionally, the locking rod has a guide rod extending upward through the linkage box, and the portion of the guide rod located outside the linkage box is threadedly connected to a limit nut.
[0013] By adopting the above technical solution, the limit nut abuts against the outer wall of the linkage box, which can restrict the guide rod and the locking rod from moving downward, thereby adjusting the position of the locking rod.
[0014] Optionally, a plurality of shredders are rotatably connected to the pressure plate, and the pressure plate has a synchronizing element for driving all the shredders to rotate simultaneously.
[0015] By adopting the above technical solution, the leaf shredder is used to shred the leaves when the pressure plate compresses them downwards, thereby further reducing the volume of the leaves and making it easier to compress them.
[0016] Optionally, each of the shredded parts includes a rotating shaft and a cutter, the rotating shaft being rotatably connected to the pressure plate and extending downward from the pressure plate, and the cutter being distributed around the outer periphery of the rotating shaft.
[0017] Optionally, the synchronizing element includes a gear ring, a driving gear, a driven gear, and a rotation source. The gear ring and the driving gear are rotatably connected to the pressure plate. The gear ring has teeth on both its inner and outer sides. The axis of the driving gear, the axis of the gear ring, and the axis of the rotating shaft are parallel to each other, and the driving gear meshes with the gear ring. The rotation source is disposed on the pressure plate to drive the driving gear to rotate. The driven gear corresponds one-to-one with the rotating shaft and is coaxially connected to the corresponding rotating shaft. The driven gear is located in the pressure plate and meshes with the inner or outer side of the gear ring.
[0018] Optionally, the top of the collection box is connected with a circumferentially connected lining, and the end of the lining away from the collection box is detachably connected to the top surface of the pressure plate.
[0019] By adopting the above technical solution, the tarpaulin can enclose the space between the collection box and the pressure plate, making it difficult for leaves to move from the top of the collection box. When the tarpaulin is removed from the top surface of the pressure plate, the top opening of the collection box is exposed, thereby improving the convenience of cleaning the collection box.
[0020] Optionally, the bottom of the collection box has a discharge port communicating with the collection chamber, and the collection box has an opening and closing member that moves at the discharge port to open and close the discharge port. The collection box also has a driving member for driving the opening and closing member to move.
[0021] By adopting the above technical solution, the opening and closing parts are driven by the driving component to open and close the discharge port of the collection box, so that the leaves fall out of the collection box after collection.
[0022] In summary, this application has the following beneficial effects: The power unit draws leaves through a suction pipe into a collection box, improving the efficiency of collecting garden leaves. The compression unit squeezes the leaves in the collection box, compressing them so that the collection box can hold more leaves. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0026] This application discloses a garden leaf collection device. (Refer to...) Figure 1 and Figure 2 The garden leaf collection device includes a collection box 1, a leaf suction pipe 2, a squeezing component 3, and a walking mechanism 4. The collection box 1 is a cylindrical shape with an open top. A collector is formed inside the collection box 1. The leaf suction pipe 2 is connected to the collection box 1 to suck leaves into the collection box 1. The squeezing component 3 moves up and down on the collection box 1 to squeeze the leaves collected in the collection box 1. The walking mechanism 4 is installed at the bottom of the collection box 1 to provide the power for the collection box 1 to move.
[0027] The walking mechanism 4 adopts a wheel or track structure. In this embodiment, omnidirectional wheels are preferred. The operator can push the collection box 1 to move by using the omnidirectional wheels. Furthermore, the wheels or tracks are equipped with a drive motor. The operator can control the walking mechanism 4 to move automatically through a remote control or automatic control system. The method of controlling the drive motor to drive the walking mechanism 4 through the control system is the prior art and will not be described in detail here.
[0028] The leaf suction pipe 2 is a rigid pipe made of plastic. The bottom of the leaf suction pipe 2 is close to the lowest point of the leaf collection device, and the top of the leaf suction pipe 2 is fixed to the wall of the collection box 1 and close to the top of the collection box 1. The wall of the collection box 1 has a connecting port 6 that connects the leaf suction pipe 2 and the collection chamber 5. The outer wall of the collection box 1 is supported by a power component 7 that works with the leaf suction pipe 2. The power component 7 is a fan. The fan provides suction to draw leaves from the bottom of the leaf suction pipe 2 into the leaf suction pipe 2 and sends the leaves through the connecting port 6 into the collection chamber 5 for collection.
[0029] Reference Figure 2 and Figure 3 The extrusion component 3 includes a moving rod 31 and a pressure plate 32. The moving rod 31 is a vertically extending square rod that coincides with the axis of the collection box 1. The pressure plate 32 is a disc with an outer diameter that is the same as the inner diameter of the collection box 1. The pressure plate 32 is sleeved on the moving rod 31 and coaxially arranged with the collection box 1 so that the cross-sectional dimensions of the pressure plate 32 are adapted to the cross-sectional dimensions of the collection cavity 5 at the collection cavity 5.
[0030] A movable component 8 is installed on the outer wall of the collection box 1. The movable component 8 is a first telescopic rod 81, which is an existing electric telescopic rod. The first telescopic rod 81 is set vertically, with its telescopic end facing upward and connected to the top of the movable rod 31 via a connecting rod. When the telescopic end of the first telescopic rod 81 extends, it drives the movable rod 31 and the pressure plate 32 to move upward. When the telescopic end retracts, it drives the movable rod 31 and the pressure plate 32 to move downward. The pressure plate 32 squeezes the leaves. A mobile power supply (not shown in the figure) is installed on the collection box 1 for the first telescopic rod 81 and the fan to be electrically connected.
[0031] Reference Figure 1 and Figure 2 To prevent the suction pipe 2 from drawing leaves above the pressure plate 32 when the pressure plate 32 moves downward to squeeze the leaves, the end of the suction pipe 2 near the collection box 1 has an opening and closing component 9 for opening and closing that end. The opening and closing component 9 includes a second telescopic rod 91 and an opening and closing plate 92. The second telescopic rod 91 is a conventional electric telescopic rod, which is installed on the outer wall of the collection box 1 and is arranged vertically. The opening and closing plate 92 is fixed to the telescopic end of the second telescopic rod 91 and passes through the suction pipe 2.
[0032] The second telescopic rod 91 is linked to the first telescopic rod 81. When the telescopic end of the first telescopic rod 81 extends, the pressure plate 32 is located above the connecting port 6. At this time, the telescopic end of the second telescopic rod 91 is in the retracted state, and the opening and closing plate 92 opens the pipe of the suction pipe 2, allowing leaves to enter the collection box 1 from the suction pipe 2. Before the telescopic end of the first telescopic rod 81 retracts, the telescopic end of the second telescopic rod 91 extends first, driving the opening and closing plate 92 to move upward and block the pipe of the suction pipe 2, thus restricting leaves from entering the collection box. Then, the telescopic end of the first telescopic rod 81 retracts, driving the pressure plate 32 to move downward and compress the leaves. In addition, the suction pipe 2 has ventilation holes in the part between the opening and closing plate 92 and the fan, so that when the opening and closing plate 92 blocks the pipe of the suction pipe 2, the sucked-in air can be blown out from the ventilation holes, balancing the pressure inside and outside the suction pipe 2, and allowing the leaves to be temporarily collected inside the suction pipe 2.
[0033] Reference Figure 3 and Figure 4Furthermore, the pressure plate 32 is slidably mounted on the moving rod 31. Near the bottom of the moving rod 31, a stop seat is fixed to prevent the pressure plate 32 from sliding down the moving rod 31. A limiting plate 10 and a linkage box 12 are also slidably mounted on the moving rod 31, located above the pressure plate 32. The linkage box 12 is located between the limiting plate 10 and the pressure plate 32. A fixing rod 27 is fixedly connected between the outer wall of the linkage box 12 and the limiting plate 10 to connect the linkage box 12 and the pressure plate 32. A first elastic element 11 is connected between the limiting plate 10 and the pressure plate 32. The first elastic element 11 is a spring sleeved on the outer periphery of the moving rod 31 and the linkage box 12. When the first elastic element 11 is in its natural state, the linkage box 12 is located in the middle position between the limiting plate 10 and the pressure plate 32. The first elastic element 11 pulls the pressure plate 32 and provides resistance when the pressure plate 32 moves towards the linkage box 12.
[0034] A vertically extending positioning rod 13 is fixed inside the moving rod 31. A long groove 15 is provided on the side of the moving rod 31, connecting the positioning rod 13 and the outside of the moving rod 31. A slot 14 is provided at the position opposite to the positioning rod 13 and the long groove 15. Multiple slots 14 are evenly spaced along the height direction of the positioning rod 13. The linkage box 12 has a portion extending into the slot 14. A horizontally sliding insertion rod 16 is provided inside the linkage box 12 opposite to the slot 14. The linkage box 12 has a linkage component 17 that cooperates with the insertion rod 16 to drive the insertion rod 16 into or out of the slot 14.
[0035] When the leaves are initially collected, the insertion rod 16 is inserted into the slot 14 near the bottom of the moving rod 31 so that the linkage box 12 and the limiting plate 10 are positioned relative to the moving rod 31. As the thickness of the leaves increases, the pressure plate 32 moves downward to compress the leaves and is limited by the thickness of the leaves, which causes the first elastic member 11 to move upward. When the pressure plate 32 moves upward to abut against the linkage box 12, it drives the linkage component 17 to move. The linkage component 17 drives the insertion rod 16 to move away from the positioning rod 13 until it disengages from the slot 14. At this time, the limiting plate 10 and the linkage box 12 move upward due to the upward push of the pressure plate 32 and the elastic force of the first elastic element 11. After the linkage box 12 moves upward and disengages from the pressure plate 32 due to the action of the first elastic element 11, the linkage component 17 drives the insertion rod 16 to move closer to the positioning rod 13, so that the insertion rod 16 is inserted into the slot 14 which is higher than the original insertion slot 14. This allows the linkage box 12 and the limiting plate 10 to be repositioned relative to the moving rod 31. The position of the pressure plate 32 on the moving rod 31 moves upward relative to the initial position so that the position of the pressure plate 32 can adapt to the thickness of the leaves in time. The pressure plate 32 is not prone to excessive movement, which could damage the device. If the linkage box 12 moves upward and there is a vertical misalignment between the insertion rod 16 and the slot 14, the linkage box 12 gradually moves downward under the gravity of itself, the limiting plate 10 and the pressure plate 32 during the upward movement of the moving rod 31. When the linkage box 12 moves downward to the point where the insertion rod 16 is opposite to the nearby slot 14, the insertion rod 16 is driven by the linkage component 17 to insert into the slot 14.
[0036] Reference Figure 4 and Figure 5 The linkage assembly 17 includes a locking rod 171, a protruding post 172, and a second elastic element 173. The locking rod 171 slides up and down on the linkage box 12 and corresponds one-to-one with the insert rod 16, and the bottom of the locking rod 171 can slide downward out of the bottom of the linkage box 12. The second elastic element 173 is a spring, which is installed in the linkage box 12 and corresponds one-to-one with the locking rod 171. The linkage box 12 has a mounting cavity for accommodating the second elastic element 173 and the locking rod 171. The two opposite ends of the second elastic element 173 abut against the top of the locking rod 171 and the top wall of the mounting cavity, respectively, to drive the bottom end of the locking rod 171 to move downward out of the linkage box 12. The protruding post 172 is fixed to one side of the locking rod 171. The side wall of the insert rod 16 opposite to the locking rod 171 has a linkage groove 18 for the protruding post 172 to slide. The extension direction of the linkage groove 18 is inclined upward along the direction close to the positioning rod 13.
[0037] Reference Figure 3 , Figure 4 and Figure 5When the pressure plate 32 is not affected by the leaves and moves away from the linkage box 12, the elastic force of the second elastic element 173 drives the locking rod 171 to move downward until the protrusion 172 abuts against the inner wall of the linkage groove 18 away from the positioning rod 13. At this time, the bottom of the locking rod 171 extends downward from the bottom of the linkage box 12, and the insertion rod 16 is inserted into the slot 14. When the pressure plate 32 is affected by the leaves and moves upward towards the linkage box 12, the pressure plate 32 gradually resists the first elastic element 11 and the second elastic element 173 to push the locking rod 171 upward, causing the locking rod 171 to move upward relative to the moving rod 31, and the protrusion 172 slides in the linkage groove 18 to drive the insertion rod 16 to move away from the positioning rod 13. When the pressure plate 32 abuts against the linkage box 12, the insertion rod 16 moves to completely disengage from the slot 14.
[0038] In this embodiment, the linkage box 12 is equipped with a plug rod 16 and a linkage component 17 opposite to the plug rod 16 on both sides. The slot 14 is opened on both sides of the positioning rod 13 and is opposite to the plug rod 16 on both sides of the linkage box 12. When the pressure plate 32 moves upward, it can simultaneously move the locking rod 171 on both sides of the linkage box 12.
[0039] Reference Figure 4 and Figure 5 Furthermore, a guide rod 19 extending upward through the linkage box 12 is fixed to the top of the locking rod 171. A second elastic element 173 is sleeved on the portion of the guide rod 19 located inside the linkage box 12. A limit nut 20 is threadedly connected to the outer wall of the guide rod 19 outside the linkage box 12. The limit nut 20 abuts against the top outer wall of the linkage box 12 to restrict the downward movement of the locking rod 171. The guide rod 19 is moved upward until the locking rod 171 is retracted into the linkage box 12. The locking nut is then screwed until it abuts against the linkage box 12, keeping the locking rod 171 in the retracted state. This keeps the insertion rod 16 disengaged from the positioning rod 13, so that after the linkage box 12 moves to a position close to the top of the moving rod 31, it can be moved back to its initial position close to the bottom of the moving rod 31.
[0040] Reference Figure 2 and Figure 6 Furthermore, to prevent leaves from being blown out of the top opening of the collection box 1 by the fan after the pressure plate 32 moves upward, a surrounding cloth 23 is connected circumferentially to the top of the collection box 1. The surrounding cloth 23 is connected end to end along the circumference of the collection box 1, and the end of the surrounding cloth 23 away from the pressure plate 32 is detachably connected to the upper surface of the pressure plate 32 by bolts. When the pressure plate 32 moves upward, it moves the surrounding cloth 23 together, so that the leaves in the collection box 1 are surrounded in the space enclosed by the pressure plate 32, the surrounding cloth 23, and the inner wall of the collection box 1.
[0041] Reference Figure 2 and Figure 3To improve the efficiency of leaf processing, multiple leaf-chopping components 21 are rotatably connected to the pressure plate 32. These components chop the leaves as the pressure plate 32 compresses them, making them easier to compress and facilitating subsequent composting or biodegradation. Specifically, each leaf-chopping component 21 includes a rotating shaft 211 and a cutter 212. The rotating shaft 211 is cylindrical, with its top rotatably connected to the pressure plate 32 and its bottom extending downwards beyond the bottom of the pressure plate 32. The axis of the rotating shaft 211 is parallel to the axis of the pressure plate 32. Each rotating shaft 211 corresponds to multiple cutters 212, which are fixedly distributed around the outer periphery of the pressure plate 32. The rotating shaft 211 rotates to drive the cutters 212 to chop the leaves. When the first telescopic rod 81 is retracted and the pressure plate 32 abuts against the anti-detachment seat, the bottom of the rotating shaft 211 approaches the inner bottom surface of the collection box 1.
[0042] Reference Figure 3 and Figure 7 To drive the rotating shaft 211 to rotate, the pressure plate 32 has a synchronizing element 22, which drives all the rotating shafts 211 on the pressure plate 32 to rotate together. The synchronizing element 22 includes a gear ring 221, a driving gear 222, a driven gear 223, and a rotation source 224. The gear ring 221 is coaxially rotatably connected to the pressure plate 32. The gear ring 221 is annular and has teeth evenly distributed circumferentially on both its inner and outer peripheral walls. The driving gear 222 is rotatably connected to the pressure plate 32. The axis of the driving gear 222 is parallel to the axis of the gear ring 221, and the driving gear 222 meshes with the teeth on the outer periphery of the gear ring 221. The rotation source 224 is a rotating motor. The rotation source 224 is installed on the upper surface of the pressure plate 32, and the output end of the rotation source 224 extends into the pressure plate 32 and is coaxially connected to the drive gear 222, so that the rotation source 224 drives the drive gear 222 to rotate, and then the drive gear 222 drives the gear ring 221 to rotate.
[0043] Driven gear 223 corresponds one-to-one with rotating shaft 211. Driven gear 223 is coaxially fixedly sleeved on the outer wall of the corresponding rotating shaft 211 and located in pressure plate 32. The rotating shafts 211 of multiple pieces 21 are distributed along the inner and outer circumferences of gear ring 221. Driven gear 223 on the rotating shaft 211 meshes with the teeth of the outer circumference of gear ring 221, and driven gear 223 on the rotating shaft 211 meshes with the teeth of the inner circumference of gear ring 221. Thus, when gear ring 221 rotates, it synchronously drives all driven gears 223 to rotate together, that is, drives all rotating shafts 211 to rotate.
[0044] Reference Figure 6 and Figure 8In addition, to facilitate the removal of leaves from the collection box 1, a discharge port 24 is provided at the bottom of the collection box 1. An opening / closing member 25 is movable at the discharge port 24. The opening / closing member 25 is plate-shaped and faces the discharge port 24. The bottom of the collection box 1 has guide rails 28 that abut against the sides and bottom of the opening / closing member 25 to prevent it from detaching downwards. A driving member 26 connected to the opening / closing member 25 is also installed on the collection box 1. The driving member 26 is a third telescopic rod 261, which is an electric telescopic rod powered by a mobile power source on the collection box 1. The telescopic end of the third telescopic rod 261 extends horizontally and is connected to one end of the opening / closing member 25. When the telescopic end of the third telescopic rod 261 retracts, it drives the opening / closing member 25 to close the discharge port 24. When the telescopic end of the third telescopic rod 261 extends, it drives the opening / closing member 25 to move away from the discharge port 24, opening the discharge port 24 and allowing the leaves to fall out.
[0045] The implementation principle of a garden leaf collection device according to an embodiment of this application is as follows: The walking mechanism 4 drives the collection box 1 to move. During the movement of the collection box 1, the fan draws leaves into the collection box 1 through the leaf suction pipe 2 for collection. After the opening and closing plate 92 closes the end of the leaf suction pipe 2 near the collection box 1, the pressure plate 32 moves downward to compress the leaves in the collection box 1. At the same time, the rotating source 224 drives the rotating shaft 211 and the cutter 212 to rotate and chop the leaves. After the pressure plate 32 moves upward to a height above the connecting port 6, the opening and closing plate 92 opens the leaf suction pipe 2 to allow the leaves to enter the collection box 1 for collection. When the leaves accumulate to a certain thickness, the leaves push the pressure plate 32 upward, causing the pressure plate 32 to resist the elastic force of the first elastic element 11. The pressure plate 32 also abuts against the locking rod 171, causing the locking rod 171 to move, thereby moving the insertion rod 16 out of the positioning rod 13. This causes the linkage box 12 and the limiting plate 10 to move upward, thereby adjusting the position of the pressure plate 32 according to the thickness of the leaves.
