Detailed Implementation

[0035] The following embodiments of this application will be described in conjunction with the accompanying drawings.

[0036] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" means that the components are connected to each other and their relative positional relationship remains unchanged after connection. "Rotary connection" means that the components are connected to each other and can rotate relative to each other after connection. The term "integral molding" means that during the formation of one of a plurality of components, that component is connected to the other components without requiring further processing (such as bonding, welding, snap-fit ​​connection, screw connection) to connect the two components together. The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," "outer," and "side," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0037] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the grass-collecting device 100 provided in the first embodiment of this application; Figure 2 yes Figure 1The diagram shows a partial structural representation of the grass-collecting device 100. The grass-collecting device 100 includes a grass-collecting state and a grass-discharging state. The grass-collecting device 100 includes a main body 10, a grass-collecting box 20, and a blocking member 30. The grass-collecting box 20 is connected to the main body 10 and has a grass-collecting cavity 201 and an opening 202 communicating with the grass-collecting cavity 201. The grass-collecting box 20 is movable relative to the main body 10, allowing the grass-collecting device 100 to switch between the grass-collecting state and the grass-discharging state. The blocking member 30 is used to block a portion of the opening 202 when the grass-collecting device 100 is in the grass-collecting state, and to open at least a portion of the opening 202 blocked by the blocking member 30 when the grass-collecting device 100 is in the grass-discharging state.

[0038] The grass collecting device 100 provided in this application is based on the addition of a shielding member 30. The shielding member 30 blocks a portion of the opening 202 when the grass collecting device 100 is in the grass collecting state, and opens at least a portion of the opening 202 covered by the shielding plate 13 when the grass collecting device 100 is in the grass unloading state. Thus, when the grass collecting state is in the grass collecting state, the shielding member 30 can prevent the grass in the grass collecting box 20 from leaking from the opening 202, while ensuring that the grass collecting device 100 can collect the grass from the part of the opening 202 that is not covered by the shielding member 30 into the grass collecting chamber 201. And when the grass unloading state is in the grass unloading state, at least a portion of the shielding member 30 can detach from the opening 202, so that the grass can be smoothly poured out of the grass collecting box 20, thereby improving the grass collecting effect and unloading efficiency of the grass collecting device 100.

[0039] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement of the main body 10, the grass collection box 20 and the shielding component 30, and not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the grass-collecting device 100 illustrated in this application embodiment is merely a schematic representation and does not constitute a specific limitation on the grass-collecting device 100. In other embodiments of this application, the grass-collecting device 100 may include... Figure 1 The components shown may include more or fewer components, combinations of certain components, or different components. For example, the grass collection device 100 may also include, but is not limited to, a detection structure. The detection structure is used to detect the amount of grass collected in the grass collection chamber 201. The detection structure may be, but is not limited to, a weight sensor, a vision sensor, etc.

[0040] The grass collection box 20 is connected to the rear of the main body 10. Exemplarily, in this embodiment, the grass collection box 20 is rotatably connected to the main body 10. Specifically, the grass collection box 20 is flip-connected to the top of the main body 10, thereby facilitating the grass unloading operation by flipping the grass collection box 20 relative to the main body 10. Of course, in some embodiments, the grass collection box 20 may also be rotatably connected to the side of the main body 10. In other embodiments, the grass collection box 20 is independently arranged relative to the main body 10 and detachably connected, allowing the user to manually unload the grass after disassembling the grass collection box 20.

[0041] Please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 3 yes Figure 1 The schematic diagram of the grass collection device 100 omitting the grass collection box 20 and the shielding member 30 is omitted. In some embodiments, the grass collection device 100 further includes a driving member 11 and a rotating rod 12. The rotating rod 12 is rotatably mounted on the main body 10. The grass collection box 20 is mounted on the rotating rod 12, and the driving member 11 is connected to the rotating rod 12 and is used to drive the rotating rod 12 to rotate the grass collection box 20 relative to the main body 10. Thus, the driving member 11 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the grass collection box 20 to rotate relative to the main body 10, realizing the automatic grass unloading function of the grass collection device 100 and improving the grass unloading efficiency.

[0042] Exemplarily, in this embodiment, the grass collection box 20 is detachably connected to the main body 10, thereby facilitating installation, disassembly, replacement, and maintenance, and providing flexibility in use. Specifically, the grass collection box 20 is provided with a rotating arm 21. The rotating arm 21 is detachably fastened to the rotating rod 12 and is used to drive the grass collection box 20 to swing around the rotation axis of the rotating rod 12, thereby realizing the detachable connection between the grass collection box 20 and the main body 10, facilitating the cleaning and maintenance of the grass collection box 20. In one possible implementation, the grass collection box 20 is non-detachably connected to the main body 10. For example, the rotating rod 12 can be non-detachably connected to the rotating arm 21, thereby improving the assembly efficiency between the rotating rod 12 and the rotating arm 21.

[0043] For example, in this embodiment, the rotating rod 12 is configured with an irregular shape. Therefore, on the one hand, under the action of gravity, the rotating arm 21 presses against the rotating rod 12, so that the rotating arm 21 is fixed relative to the rotating rod 12. Thus, when the driving member 11 drives the rotating rod 12 to swing, the rotation of the rotating rod 12 can drive the rotating rod 12 to rotate, and together with the rotating arm 21 mounted on the rotating rod 12, rotate, thereby driving the grass collection box 20 to rotate, thus realizing the rotation of the grass collection box 20 relative to the main body 10. On the other hand, it facilitates the alignment and assembly of the rotating arm 21 with the rotating rod 12, improving assembly efficiency. The rotating rod 12 can swing relative to the main body 10 in a counterclockwise or clockwise direction to realize the opening and closing movements of the grass collection box 20.

[0044] It should be noted that the term "irregular structure" refers to a structure with an irregular shape. For example, a protruding structure (i.e., the rotating rod 12) is provided on one side of the rotating rod 12 along its radial direction, resulting in an irregular structure at that end. A protruding structure refers to a structure that protrudes outward from one end of the rotating rod 12 along its radial direction. Examples include protrusions, elongated structures, needle-like structures, bent structures, or other structures, which can be flexibly selected according to the application requirements. The purpose of these structures is to enable the rotating rod 12 to drive the rotating arm 21 to rotate when the rotating arm 21 and the rotating rod 12 are engaged, and to ensure a high degree of reliability in the connection between the rotating arm 21 and the rotating rod 12.

[0045] In one possible implementation, the rotating rod 12 can also be configured as a non-irregular structure. The rotating rod 12 and the rotating arm 21 can be fixedly connected by a fixing structure, so that the rotating rod 12 drives the rotating arm 21 to rotate, which in turn drives the grass collection box 20 to rotate. The fixing structure is detachably connected to the rotating rod 12 and the grass collection box 20, thereby enabling the detachable assembly of the grass collection box 20. In one possible implementation, the rotating rod 12 can also be omitted, for example, the rotating rod 12 is directly fixedly connected to the rotating arm 21. It should be noted that the so-called non-irregular structure refers to a structure with a regular shape.

[0046] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 2For reference, the term "length direction X" can refer to the forward or backward direction of the grass collecting device 100; or it can refer to the arrangement direction of the main body 10 and the grass collecting box 20, i.e., the front-back direction (where the positive X-axis is backward). The term "width direction Y" refers to the direction parallel to the flipping axis of the grass collecting box 20, i.e., the left-right direction (where the positive Y-axis is left). The term "height direction Z" refers to the direction from the supporting plane of the grass collecting device 100 to the highest protruding part of the grass collecting device 100, i.e., the up-down direction (where the positive Z-axis is up). The length direction X, width direction YZ, and height direction Z together constitute the three orthogonal directions of the grass collecting device 100. For ease of description, the up-down, left-right, and front-back orientations in this application are relative positions and do not constitute a limitation on implementation. The length direction X, width direction YZ, and height direction Z of the grass collecting device 100 can be customized according to the specific structure of the product and the perspective presented in the accompanying drawings; this application does not impose specific limitations. The tail refers to the rear part of the grass collecting device 100 along the forward direction, and the front part refers to the front part of the grass collecting device 100 along the forward direction.

[0047] Understandably, in the grass-collecting state, the grass-collecting box 20 is closed to the main body 10, and the blocking member 30 blocks part of the opening 202. At this time, the grass-collecting box 20 can be used to temporarily store the grass clippings cut by the grass-collecting device 100. In the grass-unloading state, the grass-collecting box 20 is opened relative to the main body 10, so that the blocking member 30 can open part of the opening 202 that is blocked by the blocking member 30, thereby realizing the dumping of the grass clippings collected in the grass-collecting box 20 and improving the grass-unloading efficiency of the container device in the grass-unloading state.

[0048] Please see Figure 2 For example, in this embodiment, the opening 202 is provided on the side wall of the grass collection box 20 facing the main body 10. Therefore, the grass collection box 20 can collect grass in the forward direction of the walking device, improving the grass collection effect and efficiency. In some embodiments, the opening 202 may also be provided on the side wall or bottom wall of the grass collection box 20; this application embodiment does not specifically limit this.

[0049] In some embodiments, the opening 202 includes a first region 2021 and a second region 2022 adjacent to the first region 2021. Exemplarily, in this embodiment, the first region 2021 is located below the second region 2022, and the blocking member 30 is used to block the corresponding position of the first region 2021. Of course, in some embodiments, the first region 2021 surrounds the periphery of the second region 2022. Thus, in the grass-collecting state, the blocking member 30 can prevent grass from leaking from the grass collection box 20 through the opening 202, and in the grass-unloading state, at least a portion of the blocking member 30 can detach from the opening 202, allowing grass to be smoothly poured out of the grass collection box 20, thereby improving the grass-collecting effect and unloading efficiency of the grass-collecting device 100.

[0050] For example, the first region 2021 can be in the shape of a concave, I-shaped, U-shaped, or L-shaped. In other words, the shielding member 30 is used to shield the first region 2021 from having a concave, I-shaped, U-shaped, or L-shaped shape. For example, when the first region 2021 is located below the second region 2022, the first region 2021 can be in the shape of a concave, thereby avoiding the problem that the middle part of the shielding member 30 blocks the collection path of the grass and affects the grass collection effect of the grass collection device 100.

[0051] When the grass collecting device 100 is in the grass collecting state, the shielding member 30 is seamlessly connected to the portion of the grass collecting box 20 corresponding to the first area 2021. This prevents grass from leaking out of the grass collecting box 20 through the gap between the shielding member 30 and the grass collecting box 20, thus improving the grass collecting effect of the grass collecting device 100.

[0052] The blocking member 30 is movably connected to the grass collection box 20. When the grass collection device 100 is in the grass collection state, the blocking member 30 moves to a first position relative to the grass collection box 20 to block a portion of the opening 202. When the grass collection device 100 is in the grass unloading state, the blocking member 30 moves to a second position relative to the grass collection box 20 to open at least a portion of the opening 202 that was blocked by the blocking member 30. Thus, on the one hand, since the blocking member 30 is connected to the grass collection box 20, when the grass collection box 20 shakes during the movement of the mowing equipment, no gap will appear between the blocking member 30 and the grass collection box 20, preventing grass leakage and improving grass collection efficiency; on the other hand, the movable connection between the blocking member 30 and the grass collection box 20 ensures that the relative positional relationship and movement positioning between the blocking member 30 and the grass collection box 20 are accurate, thereby ensuring the normal operation of the grass collection device 100.

[0053] In this embodiment, for example, the shielding member 30 is rotatably connected to the bottom edge of the grass collection box 20 corresponding to the opening 202. When the grass collection device 100 is in the grass collection state, the shielding member 30 abuts against the main body 10 and the grass collection box 20. When the grass collection device 100 is in the grass unloading state, the shielding member 30 rotates relative to the grass collection box 20 towards the side closer to the main body 10 under the action of gravity and disengages from the opening 202. Thus, by setting the shielding member 30 to be rotatably connected to the lower edge of the grass collection box 20, abutting the shielding member 30 against the main body 10 and the grass collection box 20 in the grass collection state, and achieving the shielding member 30 to flip and disengage from the opening 202 by gravity in the grass unloading state, there is no need to set an additional drive mechanism to drive the shielding member 30 to flip, resulting in a simple structure, energy saving, and reduced impact force of grass clippings on the shielding member 30, thus extending the service life of the shielding member 30.

[0054] The first position can refer to the position where the shielding member 30 rotates relative to the grass collection box 20 to a first preset angle; or, the position where the shielding member 30 slides relative to the grass collection box 20 to a first preset position, wherein the first preset angle is equal to or slightly greater than the minimum rotation angle of the shielding member 30 relative to the grass collection box 20, and the first preset position is equal to or slightly greater than the minimum sliding distance of the shielding member 30 relative to the grass collection box 20. The second position can also refer to the position where the shielding member 30 rotates relative to the grass collection box 20 to a second preset angle; or, the position where the shielding member 30 slides relative to the grass collection box 20 to a second preset position, wherein the second preset angle is equal to or slightly less than the maximum rotation angle of the shielding member 30 relative to the grass collection box 20, and the second preset position is equal to or slightly less than the maximum sliding distance of the shielding member 30 relative to the grass collection box 20.

[0055] It should be noted that the first position and the second position refer to the state positions of the shielding member 30 relative to the grass collection box 20. The first position and the second position can be user-defined or are the factory default settings of the grass collection device 100. This application embodiment does not make specific limitations. For example, in this embodiment, such as Figure 1 As shown, the second position refers to the position where the blocking member 30 rotates to its maximum rotation angle relative to the grass collection box 20. At this time, the blocking member 30 is at least partially disengaged from a portion of the opening 202, thereby opening at least a portion of the opening 202 that was blocked by the blocking member 30. This avoids the problem of the blocking member 30 blocking the grass from being poured out of the grass collection chamber 201, thus improving the grass unloading efficiency and effect of the grass collection device 100. Figure 2 As shown, the first position refers to the position where the shield 30 is rotated relative to the grass collection box 20 to a stop position with the grass collection box 20, and the shield 30 abuts against at least a portion of the edge area of ​​the corresponding opening 202 of the grass collection box 20, thereby preventing grass from leaking out of the grass collection box 20.

[0056] Of course, in some embodiments, the shielding member 30 may also be slidably connected to the grass collection box 20. In other embodiments, the shielding member 30 may also be configured as a telescopic structure, wherein the shielding member 30 is compressible and foldable relative to the grass collection box 20, thereby allowing the folded member to shield or open a portion of the opening 202.

[0057] Please read again Figure 1 and Figure 3In some embodiments, the grass collecting device 100 further includes a roller brush 42, which is rotatably connected to the main body 10. The roller brush 42 is used to sweep grass from the area of ​​the opening 202 not blocked by the obstruction member 30 into the grass collecting chamber 201 when the grass collecting device 100 is in the grass collecting state. Thus, when the roller brush 42 rotates relative to the main body 10, the trajectory of the grass swept by the roller brush 42 can pass over the obstruction member 30 and enter the grass collecting box 20, thereby improving the grass collecting effect and efficiency of the grass collecting device 100. Of course, in other embodiments, the grass collecting device 100 also includes a suction structure. The suction structure transports grass from the opening 202 into the grass collecting chamber 201 through a pipe.

[0058] The roller brush 42 is used to collect debris. Exemplarily, in this embodiment, the grass-collecting device 100 includes a collecting component. The collecting component includes a support 41 and a roller brush 42. The support 41 is movably connected to the main body 10, and the roller brush 42 is rotatably connected to the support 41 and rotates relative to the support 41. Thus, on the one hand, the rotating roller brush 42 can contact the grass and absorb debris such as fallen leaves, grass blades, and chopped grass, thereby realizing the collecting function of the grass-collecting device 100; on the other hand, the movement of the support 41 relative to the main body 10 can adjust the distance between the roller brush 42 and the ground, thereby enabling the roller brush 42 to have a good grass-collecting effect. Specifically, the support 41 is rotatably connected to the main body 10, so the support 41 can swing relative to the main body 10.

[0059] The roller brush 42 includes a rolling shaft 421 and bristles 422 disposed on the rolling shaft 421. The roller brush 42 can be configured as a plastic structure. The bristles 422 can be configured as nylon bristles. For example, when the rotating roller brush 42 comes into contact with the grass, the bristles 422 bend due to frictional resistance. When leaving the grass, the bent bristles 422 exert a force tangential to the outer circumference of the contacted object, giving the contacted leaves, dead grass, and other debris an upward velocity, thus adsorbing the debris and realizing the collection function of the grass collecting device 100. The bristles 422 can have various shapes. For example, the user can select the shape of the bristles 422 according to the height, thickness, and grass type of the lawn to improve the grass collecting effect of the grass collecting device 100 under different lawn conditions.

[0060] In some embodiments, the collecting assembly 40 further includes a ground contact roller (not shown). The ground contact roller is used to contact the ground. The ground contact roller is rotatably connected to the bracket 41, and the ground contact roller can rotate relative to the bracket 41. The ground contact roller is closer to the ground than the roller brush 42, so that there is a gap between the roller brush 42 and the ground. In other words, when the roller brush 42 is mounted on the bracket 41, the lowest point of the roller brush 42 is higher than the lowest point of the ground contact roller to ensure that there is a gap between the roller brush 42 and the ground.

[0061] Understandably, since the ground-contact roller can roll and its lower end is lower than the brush 42, it will preferentially contact the ground. The ground-contact roller will apply pressure to the lawn, bending the grass in its rolling direction. At this point, the contact point between the ground-contact roller and the ground is the height of the bent grass. After the ground-contact roller has rolled over, the grass will partially regain its upright position, and the brush 42 will contact the upper part of the grass to prevent excessive resistance from causing the motor to stall and affecting the grass collection effect if it gets stuck at the grass roots. In other words, by bending the lawn, the ground-contact roller reduces the resistance of the grass to the brush 42, thereby improving the grass collection effect of the grass collection device 100. For example, when encountering a raised area, the ground-contact roller will be lifted by the terrain to prevent the brush 42 from sinking too deep into the grass roots. When the terrain is concave, the ground-contact roller will descend with the terrain, ensuring that the brush 42 does not lift too high off the ground and maintains a good grass collection effect.

[0062] In some embodiments, a guide plate 411 is also provided on the support 41. The guide plate 411 is arranged around the periphery of the roller brush 42. Thus, the guide plate 411 can guide the movement of the grass or leaves rolled up by the roller brush 42, so that more debris can be placed in the grass collection box 20, thereby improving the grass collection effect and efficiency of the grass collection device 100.

[0063] Please participate together Figure 1 Read 3 and Figure 4 4 is Figure 1 A partial cross-sectional view of the grass collecting device 100 is shown. The shielding member 30 is located at the bottom of the grass collecting box 20 corresponding to the opening 202 area, thereby reducing the leakage of grass within the grass collecting box 20 and improving the grass collecting effect. When the grass collecting device 100 is in the grass collecting state, the guide plate 411 is higher than the shielding member 30 in the height direction Z of the grass collecting device 100, thereby preventing the shielding member 30 from blocking the movement path of the grass or leaves rolled up by the roller brush 42, ensuring the grass collecting effect of the grass collecting device 100. In other words, when the grass collecting device 100 is in the grass collecting state, the distance between the top part of the guide plate 411 near the grass collecting box 20 and the ground is greater than the distance between the end of the shielding member 30 facing away from the ground and the ground.

[0064] In some embodiments, a support surface 101 is provided on the side of the main body 10 facing the grass collection box 20. When the grass collection device 100 is in the grass collection state, the support surface 101 abuts against the blocking member 30 to limit the blocking member 30 to a first position. Thus, on the one hand, the blocking member 30 can be limited between the main body 10 and the grass collection box 20 under the action of the support surface 101, improving the grass blocking effect of the blocking member 30; on the other hand, the support surface 101 can also guide the blocking member 30 to rotate towards or away from the opening 202 of the grass collection box 20, thereby improving the smoothness and stability of the movement of the blocking member 30 relative to the main body 10.

[0065] For example, in this embodiment, the support surface 101 is inclined relative to the ground. In other words, the support surface 101 is inclined downward in the height direction Z of the grass collecting device 100 toward the side closer to the grass collecting box 20. Therefore, based on the setting of the support surface 101 inclined relative to the ground, on the one hand, the support surface 101 can provide more stable support for the blocking member 30, avoiding the problem of grass leakage caused by the blocking member 30 detaching from the opening 202 in the grass collecting state, and reducing the shaking of the blocking member 30 between the main body 10 and the grass collecting box 20; on the other hand, the inclined support surface 101 can have a good guiding effect, improving the smoothness and stability of the movement of the blocking member 30 relative to the main body 10.

[0066] Please refer to the following: Figure 1 , Figure 2 and Figure 5 , Figure 5 yes Figure 1 An enlarged view of the shielding member 30 of the grass collection device 100. In some embodiments, the shielding member 30 includes a shielding portion 31 and a limiting portion 32 connected to the shielding portion 31. The shielding portion 31 is rotatably connected to the grass collection box 20. The limiting portion 32 is used to limit the shielding portion 31 to rotate relative to the grass collection box 20 to a preset angle. It can be understood that when the rotation angle of the shielding portion 31 relative to the grass collection box 20 is too large, if the grass collection box 20 closes back onto the main body 10, the shielding member 30 cannot automatically return to the position of covering part of the opening 202 under the action of gravity. When the rotation angle of the shielding portion 31 relative to the grass collection box 20 is too small, the shielding member 30 will prevent the grass from tilting and reduce the grass unloading effect of the grass collection device 100. Therefore, in this embodiment of the application, based on the provision of a limiting part 32 on the blocking part 31, when the blocking part 31 rotates relative to the grass collection box 20 towards the side closer to the main body 10 under the action of gravity, the limiting part 32 is used to limit the rotation angle of the blocking part 31 relative to the grass collection box 20. Thus, in this way, the angle between the blocking part 31 and the main body 10 can be guaranteed, so that the blocking part 31 can rotate towards the opening 202 of the grass collection box 20 under the action of the main body 10. This optimizes the structural design, avoids the problem of manually operating the blocking part 31 to block the opening 202, saves labor costs, improves the working efficiency of the grass collection device 100, and at the same time makes the grass collection device 100 have a good grass unloading effect and efficiency.

[0067] For example, in this embodiment, the limiting part 32 is bent relative to the blocking part 31. When the blocking part 31 rotates relative to the grass collection box 20 to a preset angle, the limiting part 32 stops against the bottom wall of the grass collection box 20. Thus, the limiting part 32 and the blocking part 31 are bent, and the limiting part 32 stops against the bottom wall of the grass collection box 20, so that the limiting part 32 abuts against the bottom wall of the grass collection box 20 to prevent the blocking part 31 from continuing to rotate. This ensures that the blocking part 31 can only rotate to the preset angle when the limiting part 32 stops against the grass collection box 20 under the action of gravity. On the other hand, the setting of the limiting part 32 can also improve the overall structural strength of the shielding plate 13, enhance the load-bearing capacity of the blocking part 31, and extend the service life of the shielding part 30.

[0068] In some embodiments, the limiting part 32 is configured as a telescopic structure or an elastic structure. The limiting part 32 includes a first end and a second end disposed opposite to each other. The first end of the limiting part 32 is connected to the blocking part 31, and the second end of the limiting part 32 is connected to the grass collection box 20. When the grass collection device 100 is in the grass unloading state, the blocking part 31 rotates relative to the grass collection box 20 to a preset angle. At this time, the limiting part 32 is in an unfolded state or a stretched state, and the top of the blocking part 31 disengages from a portion of the opening 202 of the grass collection box 20, thereby improving the grass unloading effect and efficiency of the grass collection device 100. When the grass collection device 100 is in the grass collecting state, the blocking part 31 abuts against the grass collection box 20. At this time, the limiting part 32 is in a folded state or a retracted state, and the top of the blocking part 31 blocks a portion of the opening 202 of the grass collection box 20, thereby improving the grass collecting effect and efficiency of the grass collection device 100.

[0069] Of course, in some embodiments, the limiting part 32 is configured as a sensor and is used to sense the rotation angle or rotation position of the blocking part 31. The grass collecting device 100 may also include a drive structure connected to the sensor, the drive structure being tractively connected to the blocking part 31, and used to drive the blocking part 31 to rotate to a first position or a second position according to the sensing signal sensed by the sensor. In some other embodiments, the limiting part 32 is configured as a control switch. The control switch is connected to the drive structure. The drive structure is used to drive the blocking part 31 to rotate to the first position or the second position according to the switching signal of the control switch.

[0070] Please refer to it again. Figures 1 to 3In some embodiments, the main body 10 is provided with baffles 13 on the outer side of the support surface 101. When the blocking member 30 blocks a portion of the opening 202, the blocking member 30 is confined between the two baffles 13. Thus, when the blocking member 30 abuts against the support surface 101, the two baffles 13 can restrict the degree of freedom of the blocking member 30 in the width direction Y of the grass collecting device 100, improving the stability and reliability of the blocking member 30 in blocking the first area 2021, preventing grass leakage, and improving the grass collecting effect and efficiency of the grass collecting device 100.

[0071] Please refer to it again. Figure 1 , Figure 2 and Figure 5 In some embodiments, the shielding member 30 includes a shielding portion 31 and a guiding portion 33. One end of the shielding portion 31 is rotatably connected to the grass collection box 20, and the other end of the shielding portion 31 is connected to the guiding portion 33. The guiding portion 33 is used to abut against the main body 10 during the process of the grass collection device 100 switching from the grass unloading state to the grass collection state, so as to drive the shielding portion 31 to rotate toward the side closer to the grass collection box 20. Thus, since the guiding portion 33 abuts against the main body 10 during the process of the grass collection device 100 switching from the grass unloading state to the grass collection state, the shielding portion 31 can be effectively guided to rotate toward the opening 202 of the grass collection box 20 under the action of the supporting surface 101, thereby improving the stability and reliability of the shielding member 30's rotation relative to the grass collection box 20.

[0072] In this embodiment, the guide portion 33 is fixedly connected to the blocking portion 31 and is used to slide against the main body 10. Specifically, the guide portion 33 has a guide surface 3301 on its side wall facing the main body 10, and the guide surface 3301 is configured as an arc-shaped surface or a wavy surface. Thus, on the one hand, the contact area between the guide portion 33 and the main body 10 is reduced, the friction is reduced, and the smoothness and reliability of the sliding of the guide portion 33 relative to the main body 10 are improved; on the other hand, the arc-shaped configuration of the guide surface 3301 can maintain a stable motion state during the sliding of the guide portion 33 relative to the main body 10, and the guide portion 33 has a buffering capacity to reduce the impact and vibration generated by the blocking member 30 during the operation of the grass collecting device 100.

[0073] Of course, in some embodiments, the guide portion 33 is rolledly connected to the blocking portion 31 and is used to roll against the body 10. The guide portion 33 can also be configured as a rolling structure, thereby reducing the friction between the guide portion 33 and the body 10.

[0074] A guide portion 33 is disposed on at least one side of the shielding portion 31 in the width direction Y of the grass collecting device 100. Exemplarily, in this embodiment, two guide portions 33 are provided, and the two guide portions 33 are respectively disposed on two sides of the shielding portion 31 in the width direction Y of the grass collecting device 100, thereby improving the uniformity of force on the shielding member 30 during the process of the grass collecting device 100 switching from the grass unloading state to the grass collecting state, extending the service life of the shielding member 30, and improving the stability and smoothness of the contact and cooperation between the shielding member 30 and the main body 10.

[0075] In some embodiments, the guide portion 33 protrudes from the side opposite to the grass collection box 20 relative to the blocking portion 31. When the grass collection device 100 is in the grass collection state, the guide portion 33 abuts against the main body 10, and the blocking portion 31 is inserted into the opening 202 of the grass collection box 20, thereby improving the sealing of the connection between the blocking portion 30 and the grass collection box 20, preventing grass leakage, and improving the grass collection efficiency and effect.

[0076] In some embodiments, the grass collection device 100 further includes a mounting rod 50. The mounting rod 50 is mounted on the edge portion of the grass collection box 20 corresponding to the opening 202. The blocking member 30 is rotatably connected to the grass collection box 20 via the mounting rod 50. Thus, on the one hand, the mounting rod 50 can serve as the keel structure of the grass collection box 20, improving the structural strength of the grass collection box 20; on the other hand, the blocking member 30 is connected to the grass collection box 20 via the mounting rod 50, reducing assembly difficulty and resulting in a simple and compact structure.

[0077] In this embodiment, the mounting rod 50 is configured as a cylindrical rod, thereby reducing the friction between the blocking member 30 and the mounting rod 50, facilitating the rotation of the blocking member 30 relative to the mounting rod 50, and enabling the mounting rod 50 to distribute pressure evenly when under stress, reducing local stress concentration and improving the stability and durability of the blocking member 30 relative to the mounting rod 50. Of course, in other embodiments, the mounting rod 50 can also be configured as a prism rod, with the portion of the mounting rod 50 connecting to the blocking part 31 having an arc-shaped or spherical protrusion.

[0078] In some embodiments, the shielding member 30 is provided with a snap-fit ​​interface 301 for engaging with the mounting rod 50. Thus, when the shielding member 30 rotates to a position that partially blocks the opening 202 of the grass collection box 20, the mounting rod 50 snaps into the snap-fit ​​interface 301, thereby improving the sealing, reliability, and stability of the connection between the shielding member 30 and the grass collection box 20, preventing grass leakage, and improving grass collection efficiency and effect.

[0079] Please refer to the following: Figure 1 , Figure 5 and Figure 6 , Figure 6 yes Figure 2A partial exploded view of the grass collection device 100. Exemplarily, in this embodiment, the mounting rod 50 includes a first rod body 51 and two second rod bodies 52 connected to both ends of the first rod body 51. The first rod body 51 is located at the bottom edge of the opening 202 and is rotatably connected to the connecting portion 34. The two second rod bodies 52 are respectively located at the two side edges of the opening 202 and are fixedly connected to the grass collection box 20. The first rod body 51 and the second rod bodies 52 can be integrally formed; or they can be detachably connected; or they can be independently arranged. This embodiment does not specifically limit the specific configuration.

[0080] Specifically, in this embodiment, the guide section 33 includes a first guide segment 331 and a second guide segment 332. The first guide segment 331 is connected to at least one sidewall of the shielding section 31 in the width direction Y of the grass collecting device 100. The second guide segment 332 is bent and connected to the first guide segment 331 and extends toward the grass collecting box 20. The second guide segment 332 is provided with a locking interface 301 to avoid interference between the second guide segment 332 and the mounting rod 50. The second guide segment 332 and the first guide segment 331 are smoothly connected, thereby enabling the second guide segment 332 to guide the shielding section 31 to rotate toward the side closer to the grass collecting box 20 during the process of the grass collecting device 100 switching from the grass unloading state to the grass collecting state, and improving the smoothness and safety of the rotation of the shielding section 31. Specifically, the second guide segment 332 is provided with a locking interface 301 to engage with the second rod 52.

[0081] In some embodiments, the shielding member 30 further includes a connecting portion 34, which connects the shielding portion 31 and the limiting portion 32. The shielding portion 31 is rotatably connected to the mounting rod 50 via the connecting portion 34, and the connecting portion 34 is configured with an arc-shaped structure. Thus, on the one hand, the arc-shaped structure can withstand increased pressure, improving the structural strength of the shielding member 30; on the other hand, the smooth lines of the arc-shaped structure facilitate the assembly of the connecting portion 34 with the mounting rod 50, and reduce the risk of scraping or bumping the connecting portion 34 during the rotation of the grass collection box 20 relative to the main body 10, thereby improving the smoothness and reliability of the shielding member 30's rotation.

[0082] In this embodiment, the shielding member 30 is configured as an integral structure. Specifically, the shielding part 31, the limiting part 32, the guiding part 33, and the connecting part 34 are integrally formed, thereby improving the reliability and stability of the connection between the shielding part 31, the limiting part 32, the guiding part 33, and the connecting part 34, and improving assembly efficiency. Of course, in some other embodiments, the shielding part 31 is detachably connected to at least one of the limiting part 32, the guiding part 33, and the connecting part 34, thereby reducing the processing and manufacturing difficulty of the shielding member 30.

[0083] In some embodiments, the shielding member 30 has an installation notch 302 on the side facing the limiting portion 32. The mounting rod 50 can pass through the installation notch 302 and be movably connected to the connecting portion 34. Thus, on the one hand, the installation notch 302 facilitates the assembly, disassembly, and maintenance of the shielding member 30 and the mounting rod 50; on the other hand, the installation notch 302 facing the limiting portion 32 prevents grass clippings from entering the gap between the mounting rod 50 and the connecting portion 34 and affecting the rotation of the shielding member 30, thereby improving the smoothness of the rotation of the shielding member 30.

[0084] Exemplarily, in this embodiment, the grass collection box 20 includes a bottom plate 22 and a surrounding plate 23, with the bottom plate 22 connected to the surrounding plate 23 to form a grass collection cavity 201. The bottom plate 22 includes a supporting portion 221 and a raised portion 222 connected to the supporting portion 221. When the grass collection device 100 is in the grass collection state, the raised portion 222 is inclined upward relative to the side of the supporting portion 221 facing the opening 202. Therefore, when the grass collection device 100 is in the grass collection state, the grass slides from the raised portion 222 into the supporting portion 221 under the direction of gravity, thereby reducing the accumulation of grass at the edge of the opening 202 of the grass collection box 20, preventing grass leakage, and thus improving the grass collection efficiency and effect. Of course, in some embodiments, the bottom plate 22 only includes the supporting portion 221. In other words, the plane on which the supporting portion 221 is located is a plane.

[0085] Please refer to it again. Figure 1 For example, in this embodiment, the grass collection box 20 includes a bottom plate 22 and a surrounding plate 23. The bottom plate 22 and the surrounding plate 23 are connected to form a grass collection cavity 201. When the grass collection device 100 is in the grass collection state, the blocking member 30 is inclined upward relative to the side of the bottom plate 22 of the grass collection box 20 facing the main body 10. Thus, when the grass collection device 100 is in the grass unloading state, the blocking member 30 can flip relative to the side of the grass collection box 20 facing the main body 10 under the action of gravity, so that the grass collection box 20 can have a good grass unloading effect; when the grass collection device 100 is in the grass collection state, the grass can slide from the blocking part 31 into the interior of the grass collection box 20 under the action of gravity, improving the grass collection efficiency.

[0086] Of course, in some embodiments, when the grass collection device 100 is in the grass unloading state, the shielding member 30 is inclined upward relative to the side of the bottom plate 22 of the grass collection box 20 facing the grass collection box 20; or, the shielding member 30 is perpendicular to the plane of the bottom plate 22. This application embodiment does not make specific limitations.

[0087] In some embodiments, the grass collecting device 100 further includes a first handle 61 and a second handle 62. The first handle 61 is disposed on the main body 10, and the second handle 62 is disposed on the grass collecting box 20. The grass collecting box 20 is detachably connected to the main body 10, and the main body 10 is detachably connected to the body of the walking device. Thus, the first handle 61 facilitates the user's grip on the grass collecting device 100, improving the user's operating experience. The second handle 62 facilitates manual flipping of the grass collecting box 20 for manual grass unloading. The detachable connection between the main body 10 and the body of the walking device allows the grass collecting device 100 to be removed when the walking device is cutting grass and reattached when collecting the cut grass, enriching the usage scenarios of the walking device. Of course, in some embodiments, the grass collecting device 100 may only include the first handle 61 and / or the second handle 62.

[0088] Please refer to the following: Figure 1 , Figure 2 , Figure 7 and Figure 8 , Figure 7 This is a structural schematic diagram of the grass collecting device 100 provided in the second embodiment of this application; and a structural schematic diagram of the grass collecting box 20 and the blocking member 30. In the second embodiment, the structure of the grass collecting device 100 is similar to that of the grass collecting device 100 in the first embodiment. The difference is that in the second embodiment, the blocking member 30 in the grass collecting device 100 is connected to the main body 10. Thus, the blocking member 30 can be directly installed on the main body 10. When the grass collecting box 20 is lowered to the flat position, the blocking member 30 blocks part of the opening 202 of the grass collecting box 20. When the grass collecting box 20 is lifted, since the blocking member 30 has not detached from the main body 10, the grass collecting box 20 moves away from the main body 10, causing the opening 202 to detach from being blocked by the blocking member 30, thereby ensuring that the grass can be smoothly poured out of the grass collecting box 20.

[0089] In this embodiment, for example, the blocking member 30 is fixedly connected to the main body 10. The two side walls of the blocking member 30 along the width direction Y of the grass collecting device 100 abut against the two side walls of the main body 10. When the grass collecting box 20 is closed to the main body 10, i.e., when the grass collecting device 100 is in the grass collecting state, the blocking member 30 blocks a portion of the opening 202. Specifically, the blocking member 30 blocks the first area 2021. When the grass collecting device 100 is in the grass unloading state, the grass collecting box 20 flips relative to the main body 10, so that the opening 202 of the grass collecting box 20 is removed from the blocking member 30, thereby improving the grass unloading efficiency of the grass collecting box 20.

[0090] In some embodiments, the blocking member 30 is movably connected to the main body 10. When the grass collecting device 100 is in the grass collecting state, the blocking member 30 can be moved to a third position relative to the main body 10 to block a portion of the opening 202. The blocking member 30 can also be moved to a fourth position relative to the main body 10 to open at least a portion of the opening 202 blocked by the blocking member 30. For example, when the amount of grass in the grass collecting box 20 is small, the blocking member 30 can be moved to the fourth position relative to the main body 10 to open at least a portion of the opening 202 blocked by the blocking member 30, thereby reducing the risk of the blocking member 30 obstructing the grass in the grass collecting path and improving the grass collecting efficiency of the grass collecting device 100. When the amount of grass in the grass collecting box 20 is large, the blocking member 30 can be moved to the third position relative to the main body 10 to block a portion of the opening 202, thereby preventing the grass from leaking from the grass collecting box 20 and improving the grass collecting effect and efficiency of the grass collecting device 100.

[0091] It should be noted that, in the following description of the second embodiment, detailed descriptions of structures identical to those in the first embodiment are omitted to avoid repetition. The structures and connection arrangements of the various components in the grass-collecting device 100 of the first embodiment that are identical to those in the grass-collecting device 100 of the second embodiment can be applied to the second embodiment, and will not be repeated here. For example, the structure of the shielding member 30 in the second embodiment is the same as that in the first embodiment. Of course, the structure of the shielding member 30 in the second embodiment can also differ from that in the first embodiment. For example, the shielding member 30 in the second embodiment may only include a shielding part 31 and a guiding part 33. When the grass-collecting box 20 is closed to the main body 10, i.e., when the grass-collecting device 100 is in the grass-collecting state, the shielding part 31 shields the first area 2021, and the snap-fit ​​interface 301 provided on the guiding part 33 snaps into the mounting rod 50. When the grass-collecting device 100 is in the grass-unloading state, the grass-collecting box 20 flips relative to the main body 10, so that the opening 202 of the grass-collecting box 20 is disengaged from the shielding member 30, thereby improving the grass-unloading efficiency of the grass-collecting box 20.

[0092] In the third embodiment, the shielding member 30 is fixedly connected to the hay collection box 20, and the shielding member 30 is configured as a deformable structure. Thus, when the shielding member 30 is not deformed, it can cover a portion of the opening 202 of the hay collection box 20. When the hay collection box 20 is flipped and lifted relative to the main body 10, the pressure exerted by the hay inside the hay collection box 20 on the shielding member 30 forces it to deform, causing it to detach from the opening 202 of the hay collection box 20, allowing the hay inside the hay collection box 20 to be poured out smoothly. When the hay unloading is complete, the pressure exerted by the hay on the shielding member 30 disappears, the shielding member 30 returns to its original state, and covers a portion of the opening 202 of the hay collection box 20.

[0093] This application embodiment also provides a walking device. The walking device includes a body and the aforementioned grass-collecting device 100. The grass-collecting device 100 is connected to the rear of the body. Optionally, the body can drive the grass-collecting device 100 to move. Specifically, the body includes a frame and drive wheels mounted on the frame. The main body 10 is detachably mounted on the frame, enriching the usage scenarios of the walking device and making it flexible in use. Of course, in some embodiments, the main body 10 and the frame can also be non-detachably connected together. The drive wheels are used to drive the frame together with the grass-collecting device 100 mounted on the frame to move on the ground. The rotation direction of the drive wheels is the same as the rotation direction of the roller, so that the roller drives the roller brush 42 to rise and fall with the undulations of the ground, avoiding direct impact between the roller brush 42 and obstacles, pits, protrusions, etc. on the ground, and maintaining a suitable distance between the roller brush 42 and the ground, thereby protecting the roller brush 42 and improving the grass-collecting effect of the roller brush 42.

[0094] The walking device may include, but is not limited to, hand-held, riding, and fully automated intelligent walking machines, etc., and this application does not limit it in this regard. The walking device can move on the ground. For example, the walking device can move on the ground by being pushed by a user. Or, for example, the walking device itself has the ability to move and can move automatically on the ground through a drive mechanism. The walking device can be configured as a lawn mower, harvester, sweeper, etc. Exemplarily, in this embodiment, the walking device is configured as a lawn mower. The walking device also includes a lawn mowing device. A lawn mowing device refers to a device used for lawn care, such as a lawn mower that can be used to trim the lawn and the grass and trees around the lawn. A grass collection device 100 is connected to the tail of the lawn mower. The grass collection device 100 is used to collect grass clippings, leaves, and other debris trimmed by the lawn mower. Of course, in some embodiments, the walking device may only include the grass collection device 100.

[0095] The walking device provided in this embodiment adopts the grass collecting device 100 provided in this application. Because the bracket 41, roller brush 42, and blocking member 30 of the grass collecting device 100 cooperate with each other, in the grass collecting state, the blocking member 30 blocks a portion of the opening 202 of the grass collecting box 20, thereby collecting fallen leaves, weeds, and other debris from the grass into the grass collecting box 20 and preventing leakage of grass from the opening 202. When the grass collecting device 100 is in the unloading state, the blocking member 30 can open at least a portion of the opening 202, allowing more grass to be unloaded from the grass collecting box 20, reducing the amount of grass remaining in the grass collecting box 20. Therefore, the grass collecting device 100 has good grass collecting and unloading effects.

[0096] The above description is merely a specific implementation of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
