In the present embodiment, the grass discharge pipe 21 is installed on the top wall of the mowing chamber 22. The specific cross-sectional shape and area of ​​the grass discharge pipe 21 are not limited, as long as the cut grass can be discharged smoothly. The cutter is rotatably mounted on the housing 23 and is located in the mowing chamber 22. The rotational mounting method is not limited, and can be installed by motor rotation, motor + reducer rotation, motor + gear transmission, etc. When the cutter rotates, it cuts the grass in the mowing chamber 22 to achieve mowing operations.

[0041] See also Figures 4 to 8 The upper wall of the grass removal pipe 21 is provided with a mounting hole 212, and a first rotating shaft 213 is fixedly connected to the mounting hole 212. One end of the baffle 30 is rotatably connected to the first rotating shaft 213, and the other end of the baffle 30 extends into the grass removal pipe 21. The baffle 30 rotates in the grass removal pipe 21 with the first rotating shaft 213 as the rotating shaft, and opens or closes the grass removal pipe 21. The specific shape of the baffle 30 is not limited, for example, it can be any shape that can achieve the closing or opening of the grass collection port 214, such as an approximately rectangular parallelepiped shape, an approximately elliptical shape, or an approximately fan-shaped shape. Preferably, in this embodiment, the baffle 30 is an approximately rectangular parallelepiped structure, and along the length direction of the baffle 30 (such as Figure 8(shown in the X-axis direction), one end of the baffle 30 is rotatably connected to the first rotating shaft 213, and the other end of the baffle 30 extends to the inside of the grass removal pipe 21. The handle 40 is fixedly connected to the baffle 30, and is located at one end of the baffle 30 close to the first rotating shaft 213. The fixed connection method can be that the handle 40 is fixedly connected to the baffle 30 by fasteners such as bolts, or the handle 40 and the baffle 30 are integrally formed. In the present embodiment, the handle 40 and the baffle 30 are separately arranged, and the handle 40 is fixedly connected to the baffle 30 by fasteners such as bolts. It should be noted that in other embodiments, the first rotating shaft 213 can also be rotatably connected to the mounting through hole 212, and the baffle 30 is fixedly connected to the first rotating shaft 213. When the baffle 30 rotates relative to the grass removal pipe 21, the first rotating shaft 213 rotates relative to the mounting through hole 212.

[0042] Specifically, one end of the handle 40 along the length direction is fixedly connected to the baffle 30, and the other end of the handle 40 along the length direction is arranged in the mounting through hole 212 and extends to the outside of the grass removal pipe 21. When the handle 40 is rotated, the handle 40 drives the baffle 30 to rotate up and down in the grass removal pipe 21 with the first rotating shaft 213 as the rotating shaft; Figure 6 When the handle 40 is rotated in the direction of the middle arrow, the baffle 30 is rotated toward the side of the upper wall of the grass discharge pipe 21 until the grass discharge pipe 21 is opened to the maximum extent; Figure 6 When the handle 40 is rotated in the direction opposite to the direction of the middle arrow, the baffle 30 rotates toward the side of the upper wall away from the grass removal pipe 21 until the grass removal pipe 21 is closed to the maximum extent. In this embodiment, the first locking body 50 is rotatably connected to the handle 40, and there are multiple options for the rotatable connection method. For example, the first locking body 50 can be rotatably connected to the handle 40 through a rotating shaft, or a boss can be provided on the handle 40, and a pin hole can be provided on the first locking body 50, and the pin hole cooperates with the boss shaft hole to achieve rotatable connection, etc.; in other embodiments, the first locking body 50 can also be rotatably connected to the baffle 30. When the baffle 30 is in the open position, the first locking body 50 is clamped between the grass removal pipe 21 and the handle 40, thereby achieving locking between the handle 40 and the grass removal pipe 21 to keep the baffle 30 in the open position.

[0043] See also Figures 8 to 11 Along the length direction of the baffle 30, the second locking body 60 is movably connected to the end of the baffle 30 away from the first locking body 50. The movably connected may refer to the second locking body 60 being rotatably connected relative to the baffle 30, or being slidably connected relative to the baffle 30, or being a combination of rotatable and slidable connection. When the baffle 30 is in the closed position, the second locking body 60 is pressed against the wall of the grass removal pipe 21, thereby realizing the locking connection between the baffle 30 and the grass removal pipe 21, so as to keep the baffle 30 in the closed position.

[0044] By arranging a handle 40 and a baffle 30 on the grass discharge pipe 21 and fixing the handle 40 to the baffle 30, the baffle 30 can be driven to rotate inside the grass discharge pipe 21 by operating the handle 40 outside the grass discharge pipe 21, so as to open or close the grass discharge pipe 21. Thus, the lawn mower 100 can be switched between the grass collecting and non-grass collecting working modes; the structure is simple and convenient to operate, and in the switching process, since there is no need to disassemble and assemble the baffle 30 and other parts back and forth, the switching time between different working modes can be saved, and the working efficiency of the lawn mower 100 can be further improved. At the same time, by setting the first locking body 50, the clamping connection between the baffle 30 and the grass discharge pipe 21 can be achieved to keep the baffle 30 in the open position; by setting the second locking body 60, the baffle 30 and the wall of the grass discharge pipe 21 can be matched and pressed to keep the baffle 30 in the closed position; this setting can respectively achieve the locking of the baffle 30 relative to the grass discharge pipe 21 in the closed and open positions, thereby ensuring the stability of the baffle 30 in closing or opening the grass discharge pipe 21 during the operation of the lawn mower 100, thereby improving the stability of the operating efficiency of the lawn mower 100 in different working modes.

[0045] See also Figures 7 to 10 In one example of the utility model lawn mower 100, a first through hole 54 is provided on the first locking body 50. The direction of the first through hole 54 may be consistent with the thickness direction of the first locking body 50, or may be other directions set at an angle to the thickness direction of the first locking body 50. Preferably, in this embodiment, the first through hole 54 passes through the thickness direction of the first locking body 50 and is consistent with the thickness direction of the first locking body 50. An accommodating cavity is formed on the handle 40. A boss 42 extending toward the inside of the accommodating cavity is formed on the side wall of the handle 40. The boss 42 is inserted into the first through hole 54. The boss 42 rotates in the first through hole 54 to achieve a rotational connection between the handle 40 and the first locking body 50. The first locking body 50 includes a first clamping portion 51. The first clamping portion 51 may be located inside the accommodating cavity, outside the accommodating cavity, or partially inside the accommodating cavity and partially outside the accommodating cavity. Preferably, in this embodiment, please refer to Figure 6 and Figure 7, the first clamping portion 51 extends to the outside of the accommodating cavity. The grass removal pipe 21 is provided with a second clamping portion 211 on the side close to the first locking body 50, and the second clamping portion 211 corresponds to the position of the first clamping portion 51. When the baffle 30 is in the open position, one end of the first clamping portion 51 is pressed and abutted against the handle 40, and the other end is pressed and abutted against the second clamping portion 211, thereby realizing the relative fixation between the first locking body 50, the handle 40 and the grass removal pipe 21 to keep the baffle 30 in the open position. With this locking method, it is only necessary to rotate the first locking body 50 to realize the fixation and disengagement between the first locking body 50, the handle 40 and the grass removal pipe 21, which is easy to operate and has a simple structure.

[0046] See also Figures 8 to 10 In an example of the utility model lawn mower 100, a first slot 43 is provided at one end of the handle 40 close to the first clamping part 51, the first clamping part 51 rotates in the first slot 43, and the side wall of the first clamping part 51 slides along the side wall of the first slot 43. A first stopper 41 is formed on the bottom wall of the first slot 43, and when the first clamping part 51 abuts and presses against the second clamping part 211, the side of the first clamping part 51 away from the second clamping part 211 abuts and presses against the first stopper 41. By providing the first stopper 41, a more stable and reliable clamping contact can be formed between the first locking body 50, the handle 40 and the grass discharge pipe 21, thereby improving the stability of the baffle 30 in the open position; at the same time, because the first slot 43 is provided, it can also guide the rotation of the first locking body 50, reduce the lateral deviation during the rotation process, and further improve the stability of the clamping contact between the first locking body 50, the handle 40 and the grass discharge pipe 21.

[0047] See also Figure 7 In an example of the utility model lawn mower 100, the contact surface 53 formed when the first pressing part 51 and the second pressing part 211 are pressed and abutted is an arcuate contact surface 53. The arcuate contact surface 53 includes a first contact surface 531 provided on the first pressing part 51 and a second contact surface 532 provided on the second pressing part 211. The first contact surface 531 and the second contact surface 532 are both coaxially arranged arcuate surfaces, and the rotation axis of the arcuate surface coincides with the axis of the first through hole 54. When the first pressing part 51 and the second pressing part 211 are pressed and abutted, the first contact surface 531 and the second contact surface 532 form an arcuate contact surface 53, which can increase the abutment area between the first pressing part 51 and the second pressing part 211, thereby further increasing the stability of the pressing and abutment between the first pressing part 51 and the second pressing part 211.

[0048] See also Figures 6 to 10In an example of the utility model lawn mower 100, the first locking body 50 also includes a rotating arm 52 extending to the outside of the grass removal pipe 21, and the rotating arm 52 is fixedly connected to the first pressing part 51, and the fixed connection method includes but is not limited to an integrally formed connection. The first through hole 54 is located between the rotating arm 52 and the first pressing part 51, and the first through hole 54 can be provided on the rotating arm 52 or on the first pressing part 51. Preferably, in this embodiment, the first through hole 54 is provided on the rotating arm 52. The end of the rotating arm 52 that is away from the first through hole 54 extends toward the outside of the grass removal pipe 21, and an angle is formed between the rotating arm 52 and the handle 40 along the circumferential direction of the first through hole 54. By providing the rotating arm 52, changing the angle between the rotating arm 52 and the handle 40 can achieve the pressing and abutting between the first pressing part 51 and the second pressing part 211, so that the rotation operation between the first locking body 50 and the handle 40 is more convenient and labor-saving.

[0049] See also Fig.10 In an example of the utility model lawn mower 100, a first elastic reset member 71 is provided between the rotating arm 52 and the handle 40. The first elastic reset member 71 can be any elastic reset member such as a tensile elastic, a compression spring, a leaf spring or a torsion spring, as long as it can play an elastic reset role in the rotation between the rotating arm 52 and the handle 40. In this embodiment, the first elastic reset member 71 is a compression spring. Along the compression direction of the compression spring, one end of the compression spring abuts against the rotating arm 52, and the other end of the compression spring abuts against the handle 40. When the first clamping portion 51 abuts and presses against the second clamping portion 211, the compression spring generates a supporting force between the handle 40 and the rotating arm 52, so that the rotating arm 52 moves away from the handle 40 along the rotation direction, thereby generating a pre-pressure between the first clamping portion 51 and the second clamping portion 211, and further enhancing the abutting and pressing force between the first clamping portion 51 and the second clamping portion 211.

[0050] See also Figure 6 and Fig.10 , further, the handle 40 is also provided with a limiting portion 44, and along the rotation direction of the rotating arm 52, the limiting portion 44 is located on the side of the rotating arm 52 away from the handle 40. The limiting portion 44 can be integrally formed and connected with the handle 40, or can be fixedly connected to the handle 40 by fasteners such as bolts. Preferably, in this embodiment, the limiting portion 44 is integrally formed and connected with the handle 40. The limiting portion 44 is located on the side of the first through hole 54 away from the first clamping portion 51. Under the action of the first elastic reset member 71, the side of the rotating arm 52 away from the handle 40 at least partially abuts against the limiting portion 44. By providing the limiting portion 44, the rotation angle of the rotating arm 52 can be limited, and then the clamping position of the first clamping portion 51 connected to the rotating arm 52 can be limited, so as to ensure the stable clamping between the first clamping portion 52 and the second clamping portion 211.

[0051] See also Fig.11 and Fig.12 In an example of the utility model lawn mower 100, a second slot 25 is provided at the connection between the grass discharge pipe 21 and the shell 23, and the second locking body 60 is slidably connected to the baffle 30, and has an extended state that can be engaged with the second slot 25 and a retracted state that is disengaged from the second slot 25. The specific cross-sectional shape of the second slot 25 is not limited, for example, it can be a rectangular cross-section, a triangular cross-section or a trapezoidal cross-section, etc., as long as it can form a snap-on stop for the inserted second locking body 60. The second locking body 60 can be slidably connected to the baffle 30 through a guide rail slider structure, or it can be slidably connected to the baffle 30 through a guide groove 32 and a guide block structure, and there is no specific limitation on this. The extended state and retracted state of the second locking body 60 refer to the second locking body 60 extending and retracting along the length direction of the baffle 30. When the baffle 30 needs to close the grass discharge pipe 21, the rotating arm 52 is pressed to rotate toward the side close to the handle 40, and at the same time, the first pressing part 51 is driven to rotate relative to the second pressing part 211 until the first pressing part 51 is disengaged from the second pressing part 211, thereby releasing the lock of the baffle 30 in the open position; then, the baffle 30 is moved along the same direction as the handle 40. Figure 6 The handle 40 is rotated in the direction opposite to the direction of the middle arrow, so that the handle 40 drives the baffle 30 to rotate toward the lower wall of the grass removal pipe 21, until the baffle 30 rotates to the second slot 25. At this time, the second locking body 60 is turned to the extended state and is engaged in the second slot 25, which can prevent the baffle 30 from shifting up and down during use, thereby keeping the baffle 30 in the closed position. When the baffle 30 needs to be disengaged from the closed position, the second locking body 60 is moved again at this time, so that the second locking body 60 is turned to the retracted state, and the engagement relationship between the second locking body 60 and the slot can be released. The baffle 30 can be disengaged from the closed position by rotating the baffle 30.

[0052] See also Fig.10In an example of the utility model lawn mower 100, a movable guide structure for guiding the movement between the second locking body 60 and the baffle 30 is provided between the baffle 30 and the second locking body 60. The movable guide structure can be of various types. For example, the movable guide structure can be a slide rail provided on the baffle 30, a slider provided at a corresponding position of the second locking body 60, and when the second locking body 60 and the baffle 30 move relative to each other, the slider slides along the slide rail, thereby playing a guiding role; or a guide groove 32 can be machined on the baffle 30, a guide block is installed at a corresponding position of the second locking body 60, and when the second locking body 60 and the baffle 30 move relative to each other, the guide block slides along the guide groove 32, thereby playing a guiding role. By providing the movable guide structure, the probability of lateral deviation during the relative movement of the second locking body 60 and the baffle 30 can be reduced, thereby improving the position accuracy of the second locking body 60 in the extended state and the retracted state, and at the same time, the probability of the second locking body 60 being stuck during the movement relative to the baffle 30 can be reduced.

[0053] See also Fig.10 In an example of the utility model lawn mower 100, the movable guide structure includes a guide groove 32 provided on the baffle plate 30 and a guide portion 61 provided on the second locking body 60, and the guide portion 61 slides along the guide groove 32. Specifically, along the thickness direction of the baffle plate 30, the guide groove 32 is located on the side of the upper wall of the baffle plate 30 facing the grass discharge pipe 21, and the guide groove 32 is an approximately rectangular groove structure with a front end opening, and a card interface 321 is formed at the front end position of the guide groove 32, and the second locking body 60 penetrates the card interface 321 and is installed in the guide groove 32, and the width dimension of the guide groove 32 matches the width dimension of the second locking body 60, and the guide portions 61 are formed on both sides of the width direction of the second locking body 60, and the guide portions 61 on both sides slide along the two side walls of the guide groove 32 respectively. In other embodiments, the guide groove 32 may be provided on the second locking body 60, and the guide portion 61 may be provided on the baffle plate 30, and the guide portion 61 may slide along the guide groove 32, which may also play a guiding role.

[0054] See also Fig.10In an example of the utility model lawn mower 100, the first locking body 50 is connected to the second locking body 60 through a connecting piece 72, and the first locking body 50 rotates relative to the handle 40 to pull the second locking body 60 to slide in the baffle 30. The first locking body 50 includes a connecting portion 56, and the connecting portion 56 and the first pressing portion 51 are located on the same side of the first through hole 54, and the connecting portion 56 is located below the first pressing portion 51 and close to the side of the baffle 30; one end of the connecting piece 72 is rotatably connected to the connecting portion 56, and the rotatable connection method can be that the connecting portion 56 is provided with a mounting hole, and the end of the connecting piece 72 is rotatably installed in the mounting hole; or it can be that the end of the connecting piece 72 is provided with a mounting hole, and a pin is installed at the corresponding position of the connecting portion 56, and the pin is rotatably connected in the mounting hole. The other end of the connecting piece 72 is fixedly connected to the second locking body 60, and the fixed connection method is not limited, and can be a clamping connection, or a bolt fixed connection, etc. The specific structure of the connecting member 72 is not limited, for example, it can be a metal wire structure, or any structure such as a profile member or a plastic rod, as long as it can pull the second locking body 60 to slide relative to the baffle 30 when the first locking body 50 rotates relative to the handle 40. By providing the connecting member 72, the operator can drive the connecting portion 56 to rotate by rotating the first locking body 50, thereby pulling the connecting member 72 to move, and the connecting member 72 pulls the second locking body 60 to slide in the baffle 30; the structure is simple and easy to operate.

[0055] See also Fig. 9 and Fig.10In an example of the utility model lawn mower 100, the connecting member 72 is a metal wire structure, and a long hole 55 is provided on the connecting portion. One end of the connecting member 72 is hooked in the long hole 55, and the other end of the connecting member 72 is connected to the second locking body 60 by a thread. Along the length direction of the baffle 30, a second stopper 31 is provided at one end of the guide groove 32 away from the second locking body 60, and a second elastic reset member 73 is provided between the second stopper 31 and the second locking body 60. When the connecting member 72 is in a tensioned state, that is, when the second locking body 60 is in a retracted state, the second elastic reset member 73 stores elastic potential energy. When the connecting member 72 is in a relaxed state, that is, when the second locking body 60 is in an extended state, the second elastic reset member 73 releases elastic potential energy. The second elastic reset member 73 can be a compression spring, a tension spring, a torsion spring, etc. In this embodiment, the second elastic reset member 73 is a compression spring, which is sleeved on the outside of the connecting member 72, and one end of the second elastic reset member 73 abuts against the second stopper 31, and the other end of the second elastic reset member 73 abuts against the second locking body 60. When the rotating arm 52 rotates toward the side close to the handle 40, the connecting member 72 is tightened, thereby pulling the second locking body 60 back, and the second elastic reset member 73 is compressed to store elastic potential energy; when the rotating arm 52 rotates toward the side away from the handle 40, the connecting member 72 returns to a relaxed state, and the second locking body 60 returns to an extended state under the action of the elastic potential energy of the second elastic reset member 73.

[0056] Generally, the mowing chamber 22 has an open structure below. During the mowing operation of the mower 100, the grass clippings can be directly discharged to the working ground through the open structure below the mowing chamber 22. However, preferably, please refer to Figure 2 , Figure 3 and Fig.13 In one example of the utility model lawn mower 100, the side wall of the housing 23 is further provided with a side discharge port 231, which is connected to the mowing chamber 22. The size and specific shape of the side discharge port 231 are determined by the specific grass discharge requirements of the lawn mower 100, and are not specifically limited here; in this embodiment, the side discharge port 231 is opened on the housing 23 close to the grass discharge pipe 21, and in other embodiments, it can also be opened at other positions. Preferably, please refer to Figures 2 to 4In this embodiment, a shielding cover 26 and a side baffle 24 are further provided at the position of the side discharge port 231. The shielding cover 26 is fixedly connected to the housing 23 above the side discharge port 231 by, but not limited to, bolts, and the shielding cover 26 extends in a direction away from the outer wall of the housing 23 to form a certain degree of shielding above the side discharge port 231, thereby reducing the probability of grass clippings and dust splashing during the discharge of grass clippings from the side discharge port 231, thereby reducing the dust phenomenon during the grass discharge process. The side baffle 24 is rotatably connected to the housing 23 above the side discharge port 231, and the side baffle 24 can open or close the second grass discharge port.

[0057] In the present invention, when the lawn mower 100 needs to perform grass collecting operation, it is assumed that the initial position of the baffle 30 is closed. At this time, the rotating arm 52 is rotated toward the side close to the handle 40, the connecting member 72 is tightened, and then the second locking body 60 is pulled back, so that the second locking body 60 is disengaged from the second slot 25, and the first elastic reset member 71 and the second elastic reset member 73 are compressed; then Figure 6 Rotate the handle 40 in the direction indicated by the middle arrow, and the handle 40 drives the baffle 30 to rotate upward until the baffle 30 opens the grass discharge pipe 21 to the maximum extent. At this time, release the rotating arm 52, and under the action of the first elastic reset member 71, the rotating arm 52 rotates toward the side away from the handle 40 until the rotating arm 52 abuts against the limiting portion 44, and at the same time drives the first clamping portion 51 to gradually clamp between the second clamping portion 211 and the first stop portion 41 of the handle 40 from bottom to top, until finally the first locking body 50, the grass discharge pipe 21 and the handle 40 are clamped and fixed, thereby keeping the baffle 30 in the open position. When the lawn mower 100 does not need to perform grass collecting operations, at this time, rotate the rotating arm 52 again toward the side close to the handle 40 to disengage the first clamping portion 51 from the second clamping portion 211, and then, along the same Figure 6 The handle 40 is rotated in the direction opposite to the direction of the middle arrow, and the handle 40 drives the baffle 3 to rotate downward until the baffle 30 rotates to the second slot 25. At this time, the rotating arm 52 is released, and under the action of the first elastic reset member 71, the rotating arm 52 rotates toward the side away from the handle 40, so that the connecting member 72 returns to the relaxed state, and the second locking body 60 returns to the extended state under the action of the elastic potential energy of the second elastic reset member 73, and is engaged in the second slot 25, thereby keeping the baffle 30 in the closed position. In this way, the baffle 30 can be switched between the open and closed states.
