The rotation of the rotating shaft 505 drives the driving gear 508 to rotate. The rotation of the driving gear 508 drives the driven gear 504 meshed therewith to rotate. The rotation of the driven gear 504 drives the connecting shaft 503 to rotate. The rotation of the connecting shaft 503 drives the cutting blade 5 to rotate, so that the cutting blade 5 extends out from the groove 3.

[0054] In order to prevent the folding tube 604 and the Christmas cactus nozzle 6 from sliding down under the action of gravity, a limiting concave plate 607 is symmetrically installed on the surface of one side of the main frame 1 close to the Christmas cactus nozzle 6, and the surface of the L-shaped plate 606 is slidably engaged with the inner wall of the limiting concave plate 607. By setting the limiting concave plate 607, the L-shaped plate 606 moves in a horizontal direction, thereby preventing the folding tube 604 from being displaced.

[0055] In order to drive the Christmas cactus nozzle 6 to rotate, a side plate 608 is fixedly installed on the surface of the limiting concave plate 607, and a driving shaft 609 is installed at the axis of the side plate 608 through a bearing.

The Christmas cactus nozzle 6 is fixedly sleeved with the surface of the driving shaft 609, and the driving shaft 609 connected to the rotating motor 610 is driven to rotate by the rotation of the output shaft. The rotation of the driving shaft 609 drives the Christmas cactus nozzle 6 to deflect, so that the Christmas cactus nozzle 6 is aimed at the weeded area.

[0056] In order to spray pesticides on the de-grassed area of ​​the lawn, the water suction end of the second suction pump 603 is extended to the inside of the liquid medicine tank 601 through a pipeline, and the water outlet end of the second suction pump 603 is fixedly connected to a diverter 611 through a pipeline. The surface of the diverter 611 is provided with nozzles 612 distributed in a rectangular array. Multiple nozzles 612 extend out of the main frame 1 and are hinged to the main frame 1 through a hinge shaft. A support plate 613 is provided on the surface of the main frame 1.

The water level in the liquid medicine tank 601 is monitored by the water level sensor 617 to facilitate reminding personnel to add liquid medicine. At the same time, the transparent glass cover facilitates the outside world to observe the liquid medicine situation inside the liquid medicine tank 601.

[0058] By setting up a spraying mechanism, the lawn and shrubs are sprayed with pesticides through the nozzle 612 and the Christmas cactus nozzle 6 respectively, so as to suppress the growth rate of weeds. At the same time, it cooperates with the cutting mechanism so that weeding and spraying can be carried out at the same time, thereby reducing the use cost and improving work efficiency.

[0059] In order to clean the grass clippings on the blade, the cleaning mechanism includes a wiping brush 4 , and the wiping brush 4 is used to clean the surface of the cutting blade 5 .

[0060] In order to drive the wiping brush 4 to move, the cleaning mechanism also includes a bidirectional lead screw 41 symmetrically installed on the inner wall of the main frame 1 through bearings. Two stepper motors 42 are fixedly installed on the upper surface of the main frame 1. One end of the output shaft of the stepper motor 42 is fixedly sleeved with one end of the bidirectional lead screw 41.

The rotation of the output shaft of the stepper motor 42 drives the bidirectional lead screw 41 connected thereto to rotate. The two stepper motors 42 run synchronously to make the two bidirectional lead screws 41 rotate synchronously. The rotation of the bidirectional lead screw 41 drives the two sliders 43 connected thereto to move relative to each other. The movement of the slider 43 drives the wiping brush 4 to move along the inner wall of the limiting groove 44.

[0061] By providing a cleaning mechanism, it is convenient to clean the grass clippings attached to the surface of the telescopic blade 510 and the cutting blade 5. As the cutting blade 5 and the telescopic blade 510 retract, the wiping brush 4 cleans the grass clippings, thereby improving the use efficiency of the cutting blade 5 and the telescopic blade 510.

[0062] Working principle: when in use, the main frame 1 is moved to the lawn that needs to be weeded, and the mower 2 at the bottom of the main frame 1 is driven by the engine in the mounting plate 501 to remove the weeds on the lawn. At the same time, the servo motor 616 is started, and the counterclockwise rotation of the output shaft of the servo motor 616 drives the transmission shaft 614 connected thereto to rotate, and the rotation of the transmission shaft 614 drives the cam 615 connected thereto to rotate, and the rotation of the cam 615 drives the nozzle 612 to deflect downward, and then the second suction pump 603 is started, and the second suction pump 603 allows the liquid medicine in the liquid medicine tank 601 to enter the diverter 611, and enter the nozzle 612 from the diverter 611, so that the liquid medicine is sprayed out through the nozzle 612 and falls on the lawn;

[0063] When it is necessary to trim the branches and leaves of low shrubs or plants, the main body frame 1 is moved close to the low shrubs, and the driving motor 507 is started. The rotation of the output shaft of the driving motor 507 drives the rotating shaft 505 connected thereto to rotate, and the rotation of the rotating shaft 505 drives the driving gear 508 to rotate. The rotation of the driving gear 508 drives the driven gear 504 meshing therewith to rotate, and the rotation of the driven gear 504 drives the connecting shaft 503 to rotate. The rotation of the connecting shaft 503 drives the cutting blade 5 to rotate, so that the cutting blade 5 extends out from the groove 3. At the same time, the rotation of the connecting shaft 503 drives the pin 509 to rotate through the transmission belt 511. The rotation of the pin 509 drives the telescopic blade 510 to rotate and extend from the bottom of the cutting blade 5, so that the cutting blade 5 and the telescopic blade 510 contact the branches and leaves of the low shrubs, and the cutting blade 5 and the telescopic blade 510 are driven to rotate under the action of the engine;

[0064] Then, the push cylinder 605 is started, and the extension of the piston rod of the push cylinder 605 drives the L-shaped plate 606 connected thereto to move along the inner wall of the limiting concave plate 607, and the movement of the L-shaped plate 606 drives the folding tube 604 to extend, and then the rotating motor 610 is started, and the rotation of the output shaft of the rotating motor 610 drives the driving shaft 609 connected thereto to rotate, and the rotation of the driving shaft 609 drives the nozzle of the Christmas cactus nozzle 6 to align downward, and then the first suction pump 602 is started, and the liquid medicine in the liquid medicine tank 601 enters the folding tube 604 through the first suction pump 602, and enters the Christmas cactus nozzle 6 from the folding tube 604, so that the liquid medicine is sprayed out through the Christmas cactus nozzle 6 and falls on the bushes;

[0065] After trimming is completed, the engine stops running and the two stepper motors 42 are started. The rotation of the output shaft of the stepper motor 42 drives the two-way lead screw 41 connected thereto to rotate. The two stepper motors 42 operate synchronously to cause the two two-way lead screws 41 to rotate synchronously. The rotation of the two-way lead screw 41 drives the two sliders 43 connected thereto to gather together. The movement of the slider 43 drives the wiping brush 4 to move along the inner wall of the limiting groove 44, so that the two wiping brushes 4 are close to each other. Then the output shaft of the driving motor 507 rotates in the opposite direction to drive the cutting blade 5 and the telescopic blade 510 to reset. As the cutting blade 5 and the telescopic blade 510 shrink, the wiping brush 4 cleans the grass clippings attached to their surface.
