[0039] The trimming mechanism 5 includes a motor 51 installed on the upper surface of the mounting plate 47. The output shaft of the motor 51 is drivingly connected to a rotating shaft 52. The lower end of the rotating shaft 52 penetrates through the mounting plate 47 and is fixedly connected to a mounting seat 53. A cutter head 54 is detachably provided at the lower end of the mounting seat 53. The motor 51 is used to drive the rotating shaft 52 so that the mounting seat 53 drives the cutter head 54 to rotate, thereby realizing the trimming work of the lawn. At the same time, the cutter head 54 is convenient to replace, and different cutter heads 54 can be replaced according to different needs of trimming the lawn.

[0040] A connecting bolt 56 is inserted into the lower surface of the cutter head 54. Two groups of positioning blocks 55 are provided on the upper surface of the cutter head 54. A threaded hole for threaded connection of the positioning bolt is formed in the lower surface of the mounting seat 53, and a positioning hole for inserting the two groups of positioning blocks 55 is formed in the lower surface of the mounting seat 53. The cutter head 54 is detachably provided, which is convenient to replace different types of cutter heads 54 to meet different trimming requirements. At the same time, the positioning blocks 55 are inserted into the positioning holes to prevent the cutter head 54 from sliding during rotation, ensuring the stability of the installation of the cutter head 54.

[0041] A handwheel 42 is installed at the upper end of the screw rod 41. A folding rubber sleeve 43 is sleeved outside the upper end of the screw rod 41. The threaded sleeve 11 is arranged in the inner cavity of the folding rubber sleeve 43. The folding rubber sleeve 43 can protect the screw rod 41, prevent dust, sundries, etc. from entering the threaded sleeve 11, ensure the smoothness of the threaded connection, and extend the service life of the height adjustment mechanism 4.

[0042] During use, the operator starts the device through the control panel 9, drives the rear wheel 2 and the auxiliary front wheel 3 to move the device to the lawn area that needs to be mowed, and according to the height of the lawn, turns the hand wheel 42 to make the screw 41 rotate in the threaded sleeve 11, thereby driving the base plate 45 to descend, so that the mowing mechanism 5 on the mounting plate 47 reaches a suitable position, and starts the motor 51, and the motor 51 drives the cutter disc 54 to rotate to mow the lawn. During the mowing process, the negative pressure fan 61 is started to generate negative pressure in the negative pressure channel 15, and then the scraper 410 scrapes up the grass clippings and sends them into the negative pressure channel 15 through the feed hole. The filter plate 7 filters the air so that the grass clippings drawn into the negative pressure channel 15 fall into the collection inner box 8. At the same time, the water pump 101 can pump out the water in the water storage chamber 18 and sprinkle water on the mowed lawn through the nozzle 104, so as to irrigate the mowed lawn and improve the lawn maintenance effect in municipal engineering.
