The grass clippings collected in the collecting chamber 24 can be taken out by opening the top cover 4.

[0030] See also Figure 2The front end of the collecting chamber 24 is provided with a suction channel 23, the front end of the suction channel 23 is an entrance, the front end of the suction channel 23 is tilted downward, and is located at the bottom of the housing 2. The picking-up and feeding mechanism 22 is installed at the entrance of the suction channel 23. The sand filter tray 25 is arranged at the bottom of the collecting chamber 24, and is used to filter out the broken sand on the grass clippings in the collecting chamber 24 and discharge it directly to the lawn below. The fan 26 is installed at the rear end of the collecting chamber 24, and the fan 26 is used to discharge the air in the collecting chamber 24 to the outside, so that a negative pressure is formed in the collecting chamber 24, thereby sucking the grass clippings sent to the entrance of the suction channel 23 by the picking-up and feeding mechanism 22 into the collecting chamber 24. Of course, a filter screen is provided at the entrance of the fan 26 to prevent a large amount of grass clippings from entering the fan 26.

[0031] See also Figure 3 The picking-up and feeding mechanism 22 includes a picking-up rod 221, a blocking structure 222 and a driving motor 223. The picking-up rod 221 is rotatably mounted in front of the entrance of the suction channel 23. The picking-up rod 221 is used to pick up grass clippings on the lawn and deliver them to the entrance of the suction channel 23. The driving motor 223 is mounted in the housing 2. The driving motor 223 is used to drive the picking-up rod 221 to rotate. The blocking structure 222 is fixedly mounted at the entrance of the suction channel 23. The blocking structure 222 is used to intercept grass clippings picked up by the picking-up rod 221 and delivered to the entrance of the suction channel 23, so that the grass clippings fall at the entrance of the suction channel 23 and are sucked into the collecting chamber 24 by the suction force generated by the fan 26.

[0032] See also Figure 4 The pick-up rod 221 includes a bearing 2211, a rotating shaft 2212, a guide piece 2213 and a transmission wheel 2214. The two ends of the rotating shaft 2212 are rotatably mounted by the bearings 2211. There are multiple guide pieces 2213. In this embodiment, guide pieces 2213 are arranged on multiple circumferences of the rotating shaft 2212, and the guide pieces 2213 on adjacent circumferences can be staggered. The part of the guide piece 2213 located below the rotating shaft 2212 will be located below the housing 2. The transmission wheel 2214 is arranged at the end of the rotating shaft 2212, and the transmission wheel 2214 is connected to the transmission wheel on the output shaft of the driving motor 223 through a transmission belt.

[0033] See also Figure 5 The guide piece 2213 is in an arc shape, and the end of the guide piece 2213 away from the rotating shaft 2212 is a tip.

[0034] The material blocking structure 222 includes a plurality of blocking pieces 2221, which are fixed side by side on the upper side of the entrance of the suction channel 23. The blocking pieces 2221 are tilted downward, and the blocking pieces 2221 are staggered with the guide pieces 2213. When the rotating shaft 2212 drives the guide pieces 2213 to rotate and pass through the entrance of the suction channel 23, the guide pieces 2213 will pass through the side of the blocking pieces 2221, and there is only a small gap between the guide pieces 2213 and the blocking pieces 2221.

[0035] During use, when the rotating shaft 2212 drives the guide piece 2213 to rotate through the grass on the lawn below the shell 2, the grass clippings on the lawn are hooked up through the cutting groove 2215 and lifted to the entrance of the suction channel 23 together with the guide piece 2213, and then intercepted from the guide piece 2213 by the blocking piece 2221 and fall into the entrance of the suction channel 23.

[0036] See also Figure 6-Figure 7 The sand filter tray 25 includes a support frame 251 and a convex plate 252. An opening is provided at the bottom of the collecting chamber 24. The support frame 251 is fixed correspondingly to the opening at the bottom of the collecting chamber 24. The convex plate 252 is fixed in the support frame 251. A plurality of notches 253 arranged side by side are provided on the convex plate 252. The periphery of the convex plate 252 is concave to form a sand collecting trough 254. A 30-degree inclined surface is provided between the sand collecting trough 254 and the convex plate 252. The bottom surface of the sand collecting trough 254 is a filter plate 255. A plurality of filter holes 256 are provided on the filter plate 255. The filter holes 256 in this embodiment are C-shaped. During use, the grass clippings collected in the collection chamber 24 will be located on the sand filter tray 25. As the lawn mower 1 moves on the lawn with the automatic collection device, the automatic collection device and the sand filter tray 25 will shake as a whole, and the broken sand on the grass clippings on the sand filter tray 25 will continue to fall onto the sand filter tray 25. As the shaking occurs, the broken sand will move to the sand collection trough 254 and fall from the filter hole 256, returning to the lawn. The notch 253 can increase the friction between the convex plate 252 and the grass clippings, and can better promote the grass clippings to turn over during the shaking process.

[0037] The use process of the automatic collection device in this embodiment is as follows:

[0038] When in use, firstly, the hook 21 is matched and hooked to the hanging hole behind the weeder 1, so that the automatic collecting device is connected to the weeder 1, and then the weeder 1 and the automatic collecting device are started. The weeder 1 moves to weed according to the remote control route or the route planned in advance, and during the movement, the automatic collecting device moves together. The driving motor 223 of the automatic collecting device will drive the picking rod 221 to rotate ( Figure 2The arrow direction in the figure is the rotation direction of the picking rod 221. When the guide sheet 2213 of the picking rod 221 moves downward, the grass clippings on the lawn will be hooked up through the cutout 2215. The grass clippings will be lifted to the entrance of the suction channel 23 together with the guide sheet 2213. When the grass clippings are lifted to the entrance of the suction channel 23, they will be intercepted by the blocking sheet 2221 and fall at the entrance of the suction channel 23. Then, they will be sucked into the collection chamber 24 under the suction force generated by the fan 26, so that the grass clippings are collected. The collected grass clippings will be located on the sand filter tray 25. As the lawn mower 1 moves on the lawn with the automatic collection device, the automatic collection device and the sand filter tray 25 will shake as a whole. The broken sand on the grass clippings on the sand filter tray 25 will continuously fall onto the sand filter tray 25, and finally fall from the filter hole 256 and return to the lawn.

[0039] After weeding is completed, the top cover 4 can be opened to take out the grass clippings collected in the collecting chamber 24. Since the sand in the grass clippings is basically filtered out, the collected grass clippings can be better used as animal feed.
