A handle 7 is provided on the upper side wall of the collecting box 2.

[0025] During use, the body 4 is started, and the four-corner moving wheels 11 on the bottom wall of the body 4 begin to rotate, allowing the lawn mower to move freely on the lawn. As the lawn mower moves, the motor and feeding device inside the body 4 drive the multiple sets of cutting blades 1 set on the bottom wall of the body 4 to start rotating, cutting the lawn. This process is a common and mature technology on the market and will not be described in detail in this article. The cut weeds are thrown to the rear of the body 4, and the absorption pump 14 is started. The absorption pump 14 and the connecting pipe 15 start working. One end of the connecting pipe 15 and the absorption pump 14 both generate strong suction. This suction is generated by the high-speed rotation of the fan or impeller driven by the motor or engine. This rotational motion creates a negative pressure area, so that the cut weeds are sucked into the pump 14 and enter the collection chamber in the collection box 2 through the connecting pipe 15. At the same time, the first motor 10 and the second motor 18 can be started according to the height of the lawn and the needs of the user. 10 output drives the rotating rod 16 to rotate, and the translation block 17 moves with the rotation of the rotating rod 16, which can drive the absorption pump 14 to move, and cooperate with the second motor 18. The output of the second motor 18 drives the auxiliary rod 20 to rotate, and the absorption pump 14 rotates accordingly. By adjusting its position and angle, the best orientation for collecting weeds is achieved. During the collection process, the sensor 24 on the upper side wall of the collection chamber monitors the amount of weeds in the collection chamber in real time. When the collection box 2 is full, the sensor 24 sends a signal to the absorption pump 14 and the alarm light 6. The absorption pump 14 adjusts the suction force according to the signal to avoid overloading the collection chamber. At the same time, the alarm light 6 lights up to remind the user to clean the collection box 2 in time. When cleaning, pull the handle 7 and pull the collection box 2 forward with force. The slider 22 slides in the slide 13 and can be removed. Open the switch door 5 to pour out the weeds. Finally, install the collection box 2 according to the above operation for convenient use next time.

[0026] During actual use, it is necessary to provide a gripping point for the user so that the user can more stably control the movement of the lawn mower. In order to meet the above requirements, in this embodiment, a hand-held rod 3 is provided on the upper side wall of the connecting plate 9.

[0027] During actual use, it is necessary to realize remote monitoring and control of the operation process of the lawn mower. In order to meet the above requirements, in this embodiment, a camera 12 is provided on the front side wall of the body 4, and the camera 12 has a built-in remote control device.
