Thus, the automatic replacement of the grass collecting bag 2 can be realized, and the replacement efficiency and the mowing efficiency of the grass collecting bag 2 are improved.

[0042] In an embodiment, as shown in Figures 1-6 The support frame 1 is vertically arranged, and the front side of the support frame 1 is provided with a grass inlet 5 corresponding to the grass outlet. The cut grass enters the grass inlet 5 on the support frame 1 from the grass outlet of the cutting mechanism, and then enters the grass collecting bag 2.

[0043] Preferably, a plurality of reinforcing ribs 13 are vertically arranged on the support frame 1, and the structural strength of the support frame 1 is improved by the reinforcing ribs 13.

[0044] Preferably, the lower part of the support frame 1 is provided with a connecting part 14 for connecting the cutting mechanism.

[0045] Preferably, the rear side of the support frame 1 is provided with a sliding groove 15 for clamping the grass collecting frame 4. The grass collecting frame 4 is clamped in the sliding groove 15.

[0046] Preferably, the grass collecting frame 4 is in the form of a square plate, and a plurality of grass collecting frames 4 are vertically stacked in the sliding groove 15 and can slide relative to the sliding groove 15. The grass collecting frame 4 is provided with a through hole 41 corresponding to the grass inlet 5, and the opening of the grass collecting bag 2 is arranged at the periphery of the through hole 41. The cut grass enters the grass inlet 5 on the support frame 1 from the grass outlet of the cutting mechanism, and then enters the grass collecting bag 2 through the grass inlet 5 on the support frame 1 and the through hole 41 on the grass collecting frame 4.

[0047] Preferably, the upper end of the grass collecting frame 4 is symmetrically provided with two clamping assemblies 42 for winding the grass collecting bag 2 on the grass collecting frame 4. The clamping assembly 42 comprises a fixing member 421 fixed to the grass collecting frame 4 and a clamping member 422 inserted into the fixing member 421. After the grass collecting bag 2 is wound, the clamping member 422 is clamped at the end of the wound grass collecting bag 2, and the grass collecting bag 2 is wound on the grass collecting frame 4. Thus, the occupied space of the grass collecting bag 2 is reduced, and the plurality of grass collecting bags 2 are conveniently placed.

[0048] Preferably, the end of the support frame 1 on the left and right sides extends rearwardly with an extension 16, the extension 16 extends inwardly with a folded edge portion 17, the lower part of the folded edge portion 17 extends inwardly with a protruding portion 18, the upper end of the protruding portion 18 extends upwardly with a stop block 19, the stop block 19 is used to block the clamping piece 422, so that the clamping piece 422 is separated from the fixing piece 421, and the rolled-up grass collecting bag 2 is unfolded, and the cut grass is stored after the grass collecting bag 2 is unfolded.

[0049] Preferably, the clamping piece 422 is located directly above the stop block 19, the fixing piece 421 is located on the inner side of the stop block 19, and when the stop block 19 blocks the clamping piece 422, the stop block 19 does not contact the fixing piece 421. Thus, the clamping piece 422 can be conveniently separated from the fixing piece 421.

[0050] The rotating body 322 includes a first support body 3221 located at the lower end of the central shaft 321 and a second support body 3222 located at the upper end of the central shaft 321, and the extension directions of the first support body 3221 and the second support body 3222 are opposite. The through hole 11 on the support frame 1 is respectively a first through hole 111 and a second through hole 112 adapted to the first support body 3221 and the second support body 3222. When the first support body 3221 and the second support body 3222 are respectively rotated to the first through hole 111 and the second through hole 112, the first support body 3221 and the second support body 3222 respectively protrude from the first through hole 111 and the second through hole 112.

[0051] The first support body 3221 and the second support body 3222 each include a semi-conical portion 32211 and a fan-shaped portion 32212, the semi-conical portion 32211 is used to connect the central shaft 321, and the fan-shaped portion 32212 is used to support the grass collecting frame 4. Thus, the first support body 3221 and the second support body 3222 can respectively correspondingly protrude alternately from the first through hole 111 and the second through hole 112.

[0052] When the grass is collected, the first supporting body 3221 protrudes from the first perforation 111, while the second supporting body 3222 is away from the second perforation 112. The first supporting body 3221 is located at the lower side of the lowermost grass collecting frame 4, and is used to support the lowermost grass collecting frame 4. When the lowermost grass collecting bag 2 is full of grass, the driving member 31 drives the central shaft 321 to rotate, so that the first supporting body 3221 is away from the first perforation 111, and the first supporting body 3221 is separated from the lowermost grass collecting frame 4. Under the action of gravity, the lowermost grass collecting frame 4 is separated from the supporting frame 1. At the same time, the second supporting body 3222 protrudes from the second perforation 112, and is located at the upper side of the lowermost grass collecting frame 4. The second supporting body 3222 is used to prevent the grass collecting frame 4 above the second supporting body 3222 from falling down. When the lowermost grass collecting frame 4 is completely separated from the supporting frame 1, the driving member 31 rotates back, the second supporting body 3222 is away from the second perforation 112, the first supporting body 3221 protrudes from the first perforation 111, and the grass collecting frame 4 above the second supporting body 3222 falls down on the first supporting body 3221. At the same time, the clamping member 422 collides with the stop block 19, the stop block 19 pushes the clamping member 422 out of the fixing member 421, and the grass collecting bag 2 is changed from the rolled state to the unfolded state, and the grass is collected. Thus, the automatic replacement of the grass collecting bag 2 is completed, and the grass collecting efficiency is greatly improved.

[0053] The lower end of the grass collecting frame 4 has a notch 43. When the grass collecting frames 4 are stacked, the notch 43 is used to provide a gap between the adjacent grass collecting frames 4, so that the rotating body 322 can enter the gap to support the grass collecting frame 4.

[0054] Preferably, a limit member 323 is provided in the middle of the actuator 32, extending perpendicularly to the first support 3221 or the second support 3222. A limit switch 121 is provided on the inner side of the fixing base 12, corresponding to the limit member 323. The limit switch 121 is used to limit the rotation angle of the drive shaft in the driver 31. The limit switch 121 is electrically connected to the driver 31 via a controller. When the limit member 323 triggers the limit switch 121, the controller controls the driver 31 to stop rotating. At this time, the first support 3221 is located within the first through-hole 111, protruding from the first through-hole 111, supporting the lowermost grass collecting frame 4, allowing grass collection. When the grass collecting bag 2 is full of grass, the controller controls the driving member 31 to move away from the limit switch 121. At this point, the second support 3222 rotates into the second through-hole 112, protruding from the second through-hole 112. The second support 3222 then rotates above the lowermost grass collecting frame 4, preventing the upper grass collecting frame 4 from falling. When the lowermost grass collecting frame 4 is completely separated from the support frame 1, the driving member 31 rotates back, the second support 3222 moves away from the second through-hole 112, and the first support 3221 rotates into the first through-hole 111, protruding from the first through-hole 111. The stopper 323 triggers the limit switch 121, and grass collecting can resume.

The drive assembly 30 is provided in the middle of the front side of the support frame 10. When the rotating body 3220 rotates to the through hole 110, the corresponding grass collecting frame 40 is pushed out from the support block 101, thereby separating the grass collecting frame 40 from the support frame 10. After the rotating body 3220 moves away from the through hole 110, the grass collecting frame 40 on the upper side of the rotating body 3220 falls down under the action of gravity and falls onto the support block 101. The grass collecting bag 20 automatically unfolds under the action of gravity, with the opening facing the front side, to collect grass. In this way, the grass collecting bag 20 can be automatically replaced, greatly improving grass collection efficiency.

[0058] Preferably, the rear end of the left and right side frames of the support frame 10 is provided with a groove 102, the rear support block 101 is arranged at the front end of the groove 102, the rear end of the left and right side frames of the grass collecting frame 40 is provided with a protruding body 103, and the length of the protruding body 103 is less than the length between the rear support block 101 and the rear frame of the support frame 10. Thus, the support block 101 can support the grass collecting frame 40, and when the rotating body 3220 pushes the grass collecting frame 40, the grass collecting frame 40 can move backward, and the support block 101 can be separated from the grass collecting frame 40.

[0059] Preferably, the inner side of the rear frame of the support frame 10 is provided with an auxiliary member 104, the contact surface of the auxiliary member 104 is arranged obliquely, and the auxiliary member 104 is used to make the upper grass collecting frame 40 accurately fall on the support block 101 when the upper grass collecting frame 40 slides downward, so as to avoid the upper grass collecting frame 40 from sliding off the groove 102 when falling.

[0060] In the present application, the grass collecting mechanism is arranged at the grass outlet of the cutting mechanism, the cut grass is discharged from the grass outlet into the corresponding grass collecting bag when the cutting mechanism performs the grass cutting task, so as to avoid the cut grass from falling on the lawn and needing to be cleaned again, and the grass cutting efficiency is improved. The rotation of the execution member is driven by the driving assembly, the grass collecting frame is separated from the support frame by the execution member, so as to realize automatic replacement of the grass collecting bag, and the replacement efficiency of the grass collecting bag and the grass cutting efficiency are improved.

[0061] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct or indirect application in other related technical fields based on the content of the specification and drawings of the present application is also included in the patent protection scope of the present application.
