Description

Technical Field

[0001] This invention relates to the field of garden tools technology, and in particular to a standing lawnmower. Background Technology

[0002] There are two main ways to handle grass clippings from a standing lawnmower: leave them on the lawn or collect them. Fine grass clippings decompose quickly, providing nutrients to the lawn, but care should be taken to avoid accumulation, as this can affect the lawn's aeration and appearance. The other method is to collect the grass clippings and process them centrally. The collected clippings can be used for composting to make organic fertilizer, achieving resource reuse.

[0003] Most existing standing lawnmowers use a side-discharge method to discharge grass clippings, which are discharged from the side of the mower and fall directly onto the freshly mowed lawn. If the amount of grass clippings discharged is large, it may form obvious accumulation on the lawn, affecting the cleanliness and appearance of the lawn. In addition, a large amount of grass clippings accumulating on the lawn surface may block sunlight, affecting the photosynthesis of the lawn and leading to poor lawn growth. Therefore, based on the above problems, this invention provides a standing lawnmower to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a standing lawnmower that, by setting up a grass collection component and a switching component, directly collects and piles up the discharged grass clippings during the mowing process, thus making it easier to centrally process the grass clippings; the switching component can not only rake the grass clippings apart, making them fall evenly onto the grass surface, but also prevent the grass clippings from blocking sunlight, improve the aeration of the lawn, and promote the healthy growth of the lawn. Through the above settings, the problem of existing standing lawnmowers affecting the cleanliness and aesthetics of the lawn during grass discharge and easily leading to poor lawn growth can be solved.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A standing lawnmower includes a body, a pedal fixedly connected to one end of the body, a grass discharge port fixedly connected to one side of the body, and a grass collection component fixedly connected to one side of the body near the grass discharge port. The grass collection component is used to assist in collecting grass clippings and is connected to the body. A switching component is used to easily adapt to different usage scenarios and is connected to the grass collection component.

[0007] Optionally, the grass collection assembly includes a fixed plate slidably connected to one side of the machine body, a first grass collection plate fixedly connected to the other end of the fixed plate, an installation groove provided at the bottom of the first grass collection plate, an obstruction rod rotatably connected inside the installation groove, a connecting plate fixedly connected to the other side of the first grass collection plate, symmetrically distributed grooves provided at the top and bottom of the connecting plate, the first grass collection plate and the connecting plate being alternately arranged in sequence, and a second grass collection plate fixedly connected to the side of the connecting plate away from the fixed plate.

[0008] Optionally, the mounting groove has an opening on one side, the bottom of the first grass collecting plate has a circular groove away from the opening of the mounting groove, and the side of the first grass collecting plate away from the opening of the mounting groove has a C-shaped groove, the C-shaped groove and the circular groove are interconnected.

[0009] Optionally, the top of the barrier rod is a rounded rectangular structure, the middle part of the barrier rod is a cylindrical structure, the bottom of the barrier rod is a spherical structure, and a rope hole is provided through the center of the barrier rod.

[0010] Optionally, the connecting plates are all fixedly connected to the center of the side of the first grass collecting plate, the thickness of the connecting plate is smaller than the thickness of the first grass collecting plate, and the outer contour of the second grass collecting plate is consistent with that of the first grass collecting plate.

[0011] Optionally, the switching assembly includes fasteners fixed to the top of the inner wall of the circular groove, the fasteners being symmetrically distributed on both sides of the inner wall of the circular groove, the inner wall of the C-shaped groove being fixedly connected with symmetrically distributed elastic plates, the inner wall of the mounting groove having a through hole on the side near the circular groove, the through hole communicating with the circular groove, and an adjusting rope being provided inside the through hole, the adjusting rope passing through the inside of the rope hole.

[0012] Optionally, the fastener is a curved elastic structure, with the top of the fastener fixedly connected to the top of the inner wall of the circular groove, and the bottom of the fastener having an outwardly curved arc.

[0013] Optionally, the elastic sheet is an S-shaped curved surface elastic structure, and the bending part of the elastic sheet is provided with uniformly distributed weakening grooves.

[0014] Optionally, the inner diameter of the through hole is the same as the inner diameter of the rope hole, and the inner diameter of the through hole is larger than the outer contour of the adjusting rope.

[0015] Optionally, a rope groove and a limiting groove are provided on one side of the second grass collecting plate, the rope groove and the limiting groove are interconnected, a pulling block is snapped into the bottom of the second grass collecting plate, and the bottom of the second grass collecting plate is provided with the fastener, the fastener and the mounting groove that are consistent with the bottom of the first grass collecting plate, and the inner wall dimension of the rope groove is larger than the outer contour dimension of the adjusting rope.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a grass collection component and a switching component, the grass collection component can not only improve the efficiency of collecting grass clippings, but also directly collect the discharged grass clippings during the mowing process, making it easier to centrally process the grass clippings; the switching component can not only rake the grass clippings apart and make them fall evenly onto the grass surface, but also reduce the obvious accumulation formed during grass removal, prevent grass clippings from blocking sunlight, improve the aeration of the lawn, and promote the healthy growth of the lawn.

[0018] By using a combination of a first grass collection board, a second grass collection board, and a connecting plate, and utilizing the elastic and flexible plastic material of these components, the system can elastically deform when encountering hard objects such as trees and stones, thus preventing damage from hard impacts. In addition, the first grass collection board, the second grass collection board, and the connecting plate are manufactured as a single piece, which simplifies the manufacturing process, makes them easier to produce, and reduces the manufacturer's capital investment.

[0019] By setting fasteners and elastic plates, and utilizing their own elastic properties, the fasteners and elastic plates can undergo elastic deformation under the compression of external forces, and recover their deformation after the external forces stop compressing. This makes the locking and limiting of the blocking rod and the pulling block more stable, which is beneficial to the structural stability of the overall device.

[0020] By setting up an adjusting rope and a pulling block, the obstruction bar has two states: when the pulling block is engaged at the bottom of the second grass collection board, the adjusting rope is in a slack state, and the obstruction bar's own weight keeps it vertically downward. When the pulling block is pulled outward, the adjusting rope causes the obstruction bar to rotate counterclockwise until it engages with the fastener and elastic plate. At the same time, the obstruction bar remains horizontal, and the pulling block engages with the limiting groove, straightening the adjusting rope. In actual operation, users can use these two states to treat the discharged grass clippings differently. When grass clippings do not need to be collected, they can be raked open to make them fall evenly onto the grass surface. When grass clippings need to be collected, they can be easily piled up and collected. Attached Figure Description

[0043] Example 1

[0044] like Figures 1 to 10 As shown, an embodiment of the present invention provides a standing lawnmower, including a body 1, a foot pedal 2 fixedly connected to one end of the body 1, a grass discharge port 3 fixedly connected to one side of the body 1, and a grass collecting component fixedly connected to one side of the body 1 near the grass discharge port 3. The grass collecting component is used to assist in collecting grass clippings and is connected to the body 1. A switching component is used to easily adapt to different usage scenarios and is connected to the grass collecting component. The standing lawnmower provided in this application is suitable for side-discharge grass. The working principle of the standing lawnmower is disclosed as prior art and will not be described in detail. In actual products, it mainly uses an engine to provide power and transmits power through a transmission. The device transmits power to the cutter head, which rotates at high speed, driving the blades to cut the grass. The blades are arranged in a spiral shape, and the cut grass is thrown to one side. The cutting height can be adjusted to meet different requirements for lawn height in different situations. The pedal 2 is connected to the parking arm. When the parking arm is not pressed against the parking switch, the engine does not start. When a person stands on the pedal 2 and presses the parking switch, the engine starts by turning the key switch. When the person leaves the pedal 2, the engine turns off. This setting further ensures the safety of use. The specific structure and working principle of the grass cutting height adjustment and the engine starting and stopping when the person leaves the pedal 2 are disclosed as existing technology and will not be described in detail.

[0045] By setting up a grass-collecting component and a switching component, the grass-collecting component can not only improve the efficiency of collecting grass clippings, but also directly collect the discharged grass clippings during mowing, making it easier to centrally process the grass clippings. The switching component can not only rake the grass clippings apart and make them fall evenly onto the grass surface, but also reduce the obvious accumulation formed during grass discharge, prevent grass clippings from blocking sunlight, improve the aeration of the lawn, and promote the healthy growth of the lawn.

[0046] As one implementation method in this embodiment, such as Figures 1 to 10 As shown, the grass-collecting assembly includes a fixed plate 5 slidably connected to one side of the body 1. A first grass-collecting plate 4 is fixedly connected to the other end of the fixed plate 5. An installation groove 8 is formed at the bottom of the first grass-collecting plate 4, and a blocking rod 9 is rotatably connected inside the installation groove 8. A connecting plate 6 is fixedly connected to the other side of the first grass-collecting plate 4. Symmetrically distributed grooves 7 are formed at the top and bottom of the connecting plate 6. The first grass-collecting plate 4 and the connecting plate 6 are alternately arranged. A second grass-collecting plate 21 is fixedly connected to the side of the connecting plate 6 away from the fixed plate 5. One side of the installation groove 8 is open. A circular groove 11 is formed at the bottom of the first grass-collecting plate 4 away from the opening of the installation groove 8. A C-shaped groove 13 is formed on the side of the first grass-collecting plate 4 away from the opening of the installation groove 8. The C-shaped groove 13 and the circular groove 11 are interconnected, providing a barrier. The top of the rod 9 is a rounded rectangular structure, the middle of the obstructing rod 9 is a cylindrical structure, and the bottom of the obstructing rod 9 is a spherical structure. A rope hole 10 is opened through the center of the obstructing rod 9. The connecting plates 6 are all fixedly connected to the center of the side of the first grass collecting plate 4. The thickness of the connecting plate 6 is smaller than the thickness of the first grass collecting plate 4. The outer contour of the second grass collecting plate 21 is consistent with that of the first grass collecting plate 4. A rope groove 18 and a limiting groove 19 are opened on one side of the second grass collecting plate 21. The rope groove 18 and the limiting groove 19 are interconnected. A pulling block 17 is snapped into the bottom of the second grass collecting plate 21. The bottom of the second grass collecting plate 21 is provided with a fastener 12, which is consistent with the bottom of the first grass collecting plate 4. The inner wall dimension of the rope groove 18 is larger than the outer contour dimension of the adjusting rope 16.

[0047] Specifically, the fixing plate 5 is slidably installed on the side of the machine body 1 near the grass discharge port 3, and the height relationship between the fixing plate 5 and the grass discharge port 3 is adjusted by the multi-level height adjustment of the fixing plate 5. The working principle of the multi-level height adjustment achieved by the sliding installation of the fixing plate 5 is disclosed as prior art and will not be described in detail. The first grass collecting plate 4 is fixedly connected to the machine body 1 by the fixing plate 5, and the first grass collecting plate 4 and the connecting plate 6 are arranged alternately (e.g., Figures 4 to 6As shown, the first grass-gathering board 4, the connecting plate 6, and the second grass-gathering board 21 are integrally manufactured structures, and the whole is made of plastic material with a certain degree of elasticity and flexibility. This plastic material can undergo elastic deformation when encountering hard objects such as trees and stones, thereby avoiding damage caused by hard collisions. The outer contour dimensions of the first grass-gathering board 4 and the second grass-gathering board 21 are the same, and the thickness of the first grass-gathering board 4 is greater than the thickness of the connecting plate 6. Grooves 7 are symmetrically provided on the top and bottom of the connecting plate 6, so that the top and bottom of the connecting plate 6 form an elastic buffer. The area is more prone to elastic deformation when encountering hard objects, thus protecting the lawnmower from damage. The spacing between adjacent first grass collecting plates 4 is adapted to the outer contour dimensions of the connecting plate 6. The first grass collecting plate 4, the connecting plate 6, and the second grass collecting plate 21 form a whole that is easy to bend and deform. The inner wall of the mounting groove 8 at the bottom of the first grass collecting plate 4 is rotatably connected to the obstructing rod 9. The bottom of the first grass collecting plate 4 and the second grass collecting plate 21 are provided with mounting grooves 8, circular grooves 11, and C-shaped grooves 13 (such as those with inner wall dimensions larger than the outer contour dimensions of the obstructing rods 9). Figures 7 to 8 As shown), the outer contour of the obstructing rod 9 is divided into three parts: the top of the obstructing rod 9 is a rounded rectangle, the middle section of the obstructing rod 9 is cylindrical, and the bottom of the obstructing rod 9 is spherical. A rope hole 10 is provided through the three parts at the center of the obstructing rod 9. A rope groove 18 and a limiting groove 19 are provided on the side of the second grass collecting plate 21 away from the fixing plate 5 (as shown). Figure 4 and Figure 6 As shown, the rope groove 18 and the mounting groove 8 are interconnected, the rope groove 18 and the limiting groove 19 are interconnected, and the inner wall dimension of the limiting groove 19 is larger than the outer contour dimension of the obstructing rod 9.

[0048] By using a combination of a first grass-collecting board 4, a second grass-collecting board 21, and a connecting plate 6, and utilizing the elastic and flexible plastic materials of these components, the system can elastically deform when encountering hard objects such as trees and stones, thus preventing damage from hard impacts. In addition, the first grass-collecting board 4, the second grass-collecting board 21, and the connecting plate 6 are manufactured as a single piece, which simplifies the manufacturing process, makes them easier to produce, and reduces the manufacturer's capital investment.

[0049] As one implementation method in this embodiment, such as Figures 1 to 6As shown, the switching assembly includes a fastener 12 fixed to the top of the inner wall of the circular groove 11. The fasteners 12 are symmetrically distributed on both sides of the inner wall of the circular groove 11. The inner wall of the C-shaped groove 13 is fixedly connected with symmetrically distributed elastic plates 14. The inner wall of the mounting groove 8 is provided with a through hole 20 on the side near the circular groove 11. The through hole 20 is interconnected with the circular groove 11. An adjustment rope 16 is provided inside the through hole 20. The adjustment rope 16 passes through the inside of the rope hole 10. The fastener 12 is a curved elastic structure. The top of the fastener 12 is fixedly connected to the top of the inner wall of the circular groove 11. The bottom of the fastener 12 has an outwardly curved arc. The elastic plate 14 is an S-shaped curved elastic structure. The bending part of the elastic plate 14 is provided with uniformly distributed weakening grooves 15. The inner diameter of the through hole 20 is the same as the inner diameter of the rope hole 10. The inner diameter of the through hole 20 is larger than the outer contour of the adjustment rope 16.

[0050] Furthermore, symmetrically distributed fasteners 12 are fixedly connected to the top of the inner wall of the circular groove 11. Six fasteners 12 are evenly distributed on both sides of the circular groove 11, avoiding the through hole 20 and the C-shaped groove 13 (e.g., Figures 7 to 8 As shown), the fastener 12 has an overall S-shaped curved elastic structure. Only the top of the fastener 12 is fixedly connected to the top of the inner wall of the circular groove 11. The other parts of the fastener 12 are not connected to the circular groove 11. The S-shaped design of the fastener 12 creates a wide-mouthed spherical space between the bottoms of the fastener 12. Elastic plates 14 are symmetrically distributed on both sides of the inner wall of the C-shaped groove 13. Weakening grooves 15 are formed through the elastic plates 14 (e.g., Figure 8 As shown, the weakening groove 15 is used to thin the elastic sheet 14. This design makes it easier for the elastic sheet 14 to bend and deform from the position of the weakening groove 15 under the action of external force. The bottom of the elastic sheet 14 has an outward curvature and abuts against the inner wall of the C-shaped groove 13. Fasteners 12 are also fixedly connected to the inner wall of the limiting groove 19 near the top, so that the fasteners 12 and the elastic sheet 14 can be used to lock and limit the blocking rod 9 and the pulling block 17.

[0051] By setting fasteners 12 and elastic plates 14, and utilizing the elastic properties of fasteners 12 and elastic plates 14, fasteners 12 and elastic plates 14 can undergo elastic deformation under the compression of external force, and recover their deformation after the external force ends the compression. This makes the locking and limiting of the blocking rod 9 and the pulling block 17 more stable, which is beneficial to the structural stability of the overall device.

[0052] Furthermore, the obstruction rod 9 is made of rigid material, and its own weight can steadily press down the adjusting rope 16 threaded through the rope hole 10, and it can always maintain a vertical downward position using its own weight. One end of the adjusting rope 16 is fixedly connected to the bottom of the fixing plate 5. The adjusting rope 16 passes through the through hole 20 and the rope hole 10 in sequence to connect the obstruction rods 9 together. The free end of the adjusting rope 16 then passes through the through hole 20 at the bottom of the second grass collecting plate 21 and is fixedly connected to the top of the pulling block 17. The pulling block 17 is engaged inside the mounting groove 8 at the bottom of the second grass collecting plate 21. Pulling the pulling block 17 outward separates it from the mounting groove 8. Since the obstruction rod 9 is rotatably connected to the inner wall of the mounting groove 8, While pulling the pull block 17 outward, the adjusting rope 16 drives the obstructing rod 9 to rotate counterclockwise. When the obstructing rod 9 passes the bottom of the fastener 12, the wide opening at the bottom of the fastener 12 facilitates the entry of the obstructing rod 9. Continuing to pull the pull block 17 causes the obstructing rod 9 to be squeezed into the spherical space formed between the fasteners 12 and the C-shaped space between the elastic plates 14. At this time, the obstructing rod 9 is in a parallel state. After ensuring that each obstructing rod 9 is properly engaged with the fastener 12 and the elastic plate 14, the pull block 17 is engaged with the limiting groove 19. The adjusting rope 16 is then taut, thereby achieving the connection between the first grass-collecting boards 4. The soft board body (such as...) between the first grass-collecting boards 4, which were originally in a vertical state with the obstructing rod 9, is now connected. Figures 4 to 8 As shown), the interaction between the first grass-collecting plates 4 in the parallel state of the obstruction rod 9 is switched (as shown). Figures 9 to 10 As shown, the obstruction rod 9 is used to increase the hardness between the first grass collection boards 4, so as to facilitate the collection of discharged grass clippings.

[0053] By setting the adjusting rope 16 and the pulling block 17 together, the obstructing rod 9 has two states: when the pulling block 17 is engaged with the bottom of the second grass collection board 21, the adjusting rope 16 is in a slack state, and the obstructing rod 9 is kept vertically downward by its own weight. When the pulling block 17 is pulled outward, the adjusting rope 16 drives the obstructing rod 9 to rotate counterclockwise until the obstructing rod 9 engages with the fastener 12 and the elastic plate 14. At the same time, the obstructing rod 9 is kept in a horizontal state, and the pulling block 17 engages with the limiting groove 19, and the adjusting rope 16 is straightened. In actual operation, the user can use the above two states to treat the discharged grass clippings in different ways. When it is not necessary to collect grass clippings, the discharged grass clippings can be raked open so that they fall evenly on the grass surface. When it is necessary to collect grass clippings, it is convenient to pile them up for collection.

[0054] Example 2

[0055] like Figures 1 to 2 He Ru Figures 11 to 13As shown, an embodiment of the present invention provides a standing lawnmower with a zero-turn walking mechanism, which is more flexible in operation. The zero-turn of the standing lawnmower is achieved through power distribution from the engine 32 and hydraulic differential control. The engine 32 shaft is connected to a pulley and an electromagnetic clutch 40: the pulley drives the rear hydraulic pump to power the walking system; the electromagnetic clutch 40 controls the front blade pulley, independently starting and stopping the blades. The hydraulic pump controls the direction and speed of the two drive wheels through an oil circuit: when the left hydraulic pump rotates forward and the right hydraulic pump rotates in reverse, the two drive wheels generate opposing driving forces, causing the lawnmower to rotate in place around its central axis, forming a zero-radius turn. Through the differential control of the hydraulic system, the limitations of traditional mechanical steering are overcome, allowing for flexible operation in complex terrain. Simultaneously, the electromagnetic clutch 40 enables independent control of the blades and the walking system, improving operational safety and efficiency. The specific structure and working principle of the standing lawnmower achieving zero-turn are disclosed as prior art and will not be elaborated further here.

[0056] As one implementation method in this embodiment, such as Figures 1 to 2 As shown, the rear wheel 22 is the drive wheel, usually driven independently by a hydraulic motor or electric motor. Steering is achieved through the speed difference between the two sides. It also bears the weight of the main components such as the engine 32 and hydraulic system, providing power for forward or backward movement. The ground wheel 23 assists in supporting the weight of the entire machine, preventing the lawnmower from tilting, and maintaining stability, especially on uneven terrain. The front wheel 24 is the guide wheel, which has no driving function and mainly serves to guide steering. It is lightweight and flexible, making it easy for the operator to control the direction of the lawnmower. It also shares some of the weight of the machine body, reducing the load on the rear wheel 22. The three work together to achieve walking, steering, and machine balance.

[0057] Furthermore, the mowing height adjustment is achieved through the mechanical linkage of the lifting handle 28, the height adjustment plate 29, the connecting rod 30, and the lifting arm 31 (e.g., Figures 1 to 2 As shown, the lifting handle 28 on the side of the motor body is pulled. The handle rotates around the hinge point, and the pulling force is transmitted to the lifting arm 31 through the connecting rod 30. The connecting rod 30 drives the lifting arm 31 to swing around the fixed axis. The other end of the arm is connected to the blade holder, which in turn pushes the blade to rise and fall vertically. The height adjustment plate 29 is provided with multiple positioning holes (corresponding to different mowing heights). When the handle is pulled to the target height, the pin at the top of the connecting rod 30 is inserted into the corresponding hole of the adjustment plate to lock the position of the blade. The specific structure and working principle of the mowing height adjustment are disclosed as prior art and will not be described in detail here.

[0058] Furthermore, the belt drive and blade arrangement of the lawnmower's working part (such as...) Figure 13As shown, different pulleys play different roles. Through the coordinated operation of various components, high efficiency and durability are ensured. The pulleys are wound around the drive pulley of the engine 32 and the blade pulley 39. The blade pulley 39 is rigidly connected to the blade, which directly transmits power to drive the cutting. The pressure pulley 37 presses against the belt with elastic pressure to enhance the transmission friction and prevent slippage. The tension pulley has a wide groove and is mounted on a swing arm. The swing arm is adjusted via a handle or hydraulic mechanism. Changing the position of the tension pulley 38 adjusts the belt tension. When adjusting the mowing height, the overall lifting of the front chassis 33 changes the belt position. The wide groove of the tension pulley allows the belt to move up and down within the groove, preventing excessive friction between the belt and the groove edge, guiding the belt movement, reducing wear, and extending service life. It also ensures stable transmission of the belt at different mowing heights, ensuring continuous and efficient blade operation. The pulley guard 34 primarily protects the operating pulley, preventing weeds, gravel, and other foreign objects from getting caught in the pulley, avoiding belt wear or breakage, and ensuring the normal operation of the transmission system. It also prevents operators from accidentally touching the high-speed rotating pulley, avoiding scratches, entanglement, and other safety accidents. Its robust material also reduces damage to the pulley from external impacts, extending the service life of the components.

[0059] Furthermore, during operation, the operator stands on pedal 2, leans against backrest 27, and holds onto armrest 25. They control the machine's movement and operation via operating handle 26. When the operator stands on pedal 2, their own weight causes pedal 2 to press down, driving parking arm 35 to press parking switch 36 (e.g., ...). Figure 12 (As shown), when the circuit is connected, the engine 32 can be started and run only when the operator is in the normal operating position, ensuring that the machine can only operate when the operator is in the normal operating position, preventing accidental starting without human control. Once the operator leaves pedal 2, pedal 2 resets (as shown). Figure 11 As shown, when the parking arm 35 loses pressure and no longer presses against the parking switch 36, the circuit is disconnected, the engine 32 immediately shuts off, and the machine stops working. This mechanism can quickly cut off the power when the operator leaves due to an emergency, effectively preventing the lawnmower from going out of control, reducing safety risks, and providing reliable safety assurance for the operation.

[0060] The working principle of the technical solution provided by this invention is as follows:

[0061] When using the lawnmower, place it on a flat surface, pull the handle to start the engine, adjust the mowing height to the appropriate setting, stand on foot pedal 2, hold the handle, maintain balance, and push the lawnmower forward. The machine will automatically cut the grass in front. Before use, adjust the position between the height of the fixed plate 5 and the mowing height according to whether grass clippings need to be collected. If grass clippings do not need to be collected, after adjusting the mowing height, adjust the height of the fixed plate 5 so that the bottom height of the first grass collection plate 4 is higher than the height of the cutting blade, and ensure that the obstruction rod 9 extends below the cutting surface, so that the obstruction rod 9 can rake the discharged grass clippings and make them fall evenly onto the grass surface. The obstruction rod 9 starts under its own weight. The obstruction bar 9 maintains a vertically downward position. Its own weight steadily presses down on the adjusting rope 16 threaded through the rope hole 10, ensuring a consistently vertical downward orientation. The adjusting rope 16 passes through the through hole 20 and the rope hole 10, thus connecting the obstruction bar 9 in series. The pull block 17 is engaged with the bottom of the second grass collection plate 21. The first grass collection plate 4, the connecting plate 6, and the second grass collection plate 21 are integrally manufactured structures, made entirely of a plastic material with a certain degree of elasticity and flexibility. This plastic material can undergo elastic deformation when encountering hard objects such as trees and stones, thus preventing damage from hard collisions. As the lawnmower moves forward, the obstruction bar 9 rakes apart the freshly discharged grass clippings, ensuring they are evenly distributed. The grass clippings are evenly distributed onto the grass surface to prevent them from blocking sunlight and affecting the healthy growth of the lawn. If grass clippings need to be collected, after adjusting the mowing height, adjust the height of the fixing plate 5 so that the bottom height of the first grass collection plate 4 is lower than the height of the cutting blade. This facilitates the accumulation and collection of the discharged grass clippings by the obstruction rod 9. Then, pull the pull block 17 outwards to separate it from the mounting groove 8. Since the obstruction rod 9 is rotatably connected to the inner wall of the mounting groove 8, while pulling the pull block 17 outwards, the adjusting rope 16 drives the obstruction rod 9 to rotate counterclockwise. When the obstruction rod 9 passes the bottom of the fastener 12, the wide opening at the bottom facilitates its entry. Continue pulling the pull block 17. The obstructing rod 9 is squeezed into the spherical space formed between the fasteners 12 and the C-shaped space between the elastic plates 14. At this time, the obstructing rod 9 is in a parallel state. After ensuring that each obstructing rod 9 is properly engaged with the fasteners 12 and the elastic plates 14, the pulling block 17 is engaged with the limiting groove 19. The adjusting rope 16 is just straightened, thereby realizing the combination between the first grass collecting boards 4. The soft boards between the first grass collecting boards 4 in the original state of the obstructing rod 9 being vertical are switched to the mutual combination between the first grass collecting boards 4 in the state of the obstructing rod 9 being parallel. The obstructing rod 9 is used to increase the hardness between the first grass collecting boards 4, so that the discharged grass clippings can be collected and piled up. Then, grass bags are used to collect the grass clippings for centralized processing.This device not only improves the efficiency of grass clipping collection, but also directly collects and piles up the discharged grass clippings during mowing, making centralized processing easier. It can also rake the clippings apart, distributing them evenly across the lawn surface. This design reduces noticeable accumulation during mowing, prevents clippings from blocking sunlight, improves lawn aeration, and promotes healthy lawn growth.
