[0024] In order to make the content of the utility model more easily understood, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.
[0025] As Figures 1 to 4As shown, a lawn mower baffle, comprising a mounting seat 1, the upper side of the mounting seat 1 is fixedly connected with a motor seat 2, the upper side of the motor seat 2 is connected with a servo motor 3, the output end of the servo motor 3 is fixedly connected with a rotating rod 4, the end of the rotating rod 4 is rotatably connected to one side of the mounting seat 1, the outer side of the rotating rod 4 is connected with a hinged chain 5 at both ends, the top of the two hinged chains 5 is fixedly connected with a support frame 6, the inside of the support frame 6 is provided with a fixing mechanism 7, the upper side of the support frame 6 is fixedly connected with two arc-shaped protective plates 8, the two arc-shaped protective plates 8 can protect the fixing mechanism 7 from being splashed by grass clippings. The rotating rod 4 is driven to rotate by the servo motor 3, and the rotating rod 4 drives the support frame 6 to move through the hinged chain 5. This makes the angle of the baffle 9 can be flexibly adjusted according to the actual mowing situation. When the lawn mower is working along the slope, the baffle 9 can be adjusted to the appropriate inclination angle to better block the grass clippings. In different terrains or mowing modes, this adjustable angle design can effectively improve the blocking effect, which has great advantages compared with the traditional fixed-angle baffle 9.
[0026] The fixing mechanism 7 comprises a motor plate 701, the upper side of the motor plate 701 is connected with a bidirectional motor 702, the two output ends of the bidirectional motor 702 are fixedly connected with rotating rods 703, the ends of the two rotating rods 703 are fixedly connected with first bevel gears 704, one side of the two first bevel gears 704 is meshed with a second bevel gear 705, the upper side of the support frame 6 is fixedly connected with a fixed plate 706, one side of the second bevel gear 705 is fixedly connected with a lead screw 707, the end of the lead screw 707 is rotatably connected to one side of the fixed plate 706, the outer side of the lead screw 707 is threadedly connected with movable blocks 708 at both ends, one side of the two movable blocks 708 is connected with rotating members one 709, the inner side of the two rotating members one 709 is rotatably connected with rotating rods two 710, the ends of the two rotating rods two 710 are connected with rotating members two 711, one side of the two rotating members two 711 is fixedly connected with clamping plates 712. The baffle 9 is placed between the two clamping plates 712. The rotating rods 703 are driven to rotate by starting the bidirectional motor 702, the first bevel gears 704 on the rotating rods 703 are meshed with the second bevel gear 705, and then the lead screw 707 is rotated.
