Detailed Implementation
[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:
[0020] See Figures 1-3 This embodiment discloses a lawnmower baffle, which includes a first baffle 11 and a second baffle 12. The first baffle 11 includes a first plate body 111 and a first mounting side plate 112 disposed at the mounting end of the first plate body 111. The second baffle 12 includes a second plate body 121 and a second mounting side plate 122 disposed at the mounting end of the second plate body 121. The first plate body 111 and the second plate body 121 overlap and are spliced to form an arc-shaped baffle, and the first plate body 111 and the second plate body 121 can slide relative to each other in the length direction of the arc-shaped baffle to adjust the length of the arc-shaped baffle. The baffle is formed by two relatively sliding baffles overlapping each other, and the size of the baffle can be adjusted according to the size of the machine frame, making it highly adaptable.
[0021] A first strip-shaped hole 113 is formed on the first plate 111, and a second strip-shaped hole 123 is formed on the second plate 121. The first strip-shaped hole 113 and the second strip-shaped hole 123 are at least partially aligned, and both extend along the length direction of the arc-shaped baffle. Positioning components are installed in the first strip-shaped hole 113 and the second strip-shaped hole 123, wherein the positioning components are positioning pins 13 and locking caps. The cooperation between the two strip-shaped holes and the positioning components improves the splicing stability of the two baffles.
[0022] To ensure that the grass clippings accurately enter the collection hopper, the inner wall of the first plate 111 is formed with a first grass-guiding rib 114, and the inner wall of the second plate 121 is formed with a second grass-guiding rib 124. Both the first and second grass-guiding ribs 114 and 124 are inclined in the same direction. Because the cutting roller is inclined, the trajectory of the grass clippings may deviate. The grass-guiding ribs correct this trajectory, ensuring that the grass clippings accurately enter the collection hopper and improving the collection efficiency.
[0023] Both the first guide rib 114 and the second guide rib 124 are arc-shaped strips. The thickness of the first guide rib 114 and the second guide rib 124 gradually decreases from top to bottom to improve the correction effect. The first plate 111 is provided with one first guide rib 114, and the first guide rib 114 is set close to the first assembly side plate 112 to ensure that the second baffle 12 can slide smoothly. The second plate 121 is provided with four second guide ribs 124, and the second guide ribs are spaced apart along the length direction of the second plate 121.
[0024] The first plate 111 and the second plate 121 have the same height and curvature. The upper and lower edges of the first plate 111 are respectively formed with a first inner retaining edge 115 and a second inner retaining edge 116. The first inner retaining edge 115 is folded inwards and defines an upper guide groove with the first plate 111. The second inner retaining edge 116 is folded inwards and defines a lower guide groove with the first plate 111. The upper edge of the second plate 121 is inserted into the upper guide groove, and the lower edge of the second plate 121 is inserted into the lower guide groove. The first inner retaining edge 115 and the second inner retaining edge 116 are symmetrically arranged and located at the adjustment end of the first plate 111. The two inner retaining edges guide the sliding of the two plates and improve the stability of their joint.
[0025] The first assembly side plate 112 and the second assembly side plate 122 are symmetrically arranged on both sides of the arc-shaped baffle. Both the first assembly side plate 112 and the second assembly side plate 122 include a first side wing plate 125, a second side wing plate 126, and a bent plate. The bent plate is connected to the arc-shaped baffle via the first side wing plate 125 and the second side wing plate 126, with the first side wing plate 125 located above the second side wing plate 126. The first side wing plate 125 is inwardly folded relative to the arc-shaped baffle, and the second side wing plate 126 is outwardly folded relative to the arc-shaped baffle. The bent plate includes an inclined section 1271 and a vertical section 1272. The inclined section 1271 and... The first side wing plate 125 is connected, and the vertical section 1272 is connected to the second side wing plate 126; a groove 1273 is formed on the inclined section 1271, and the groove 1273 and the inclined section 1271 together define an assembly groove that mates with the frame; the bottom of the second side wing has an upper concave notch, and the vertical section 1272 and the second side wing together define a locking groove that mates with the frame. The assembly side plate adopts the above structure, which facilitates the disassembly and assembly of the grass barrier while ensuring its assembly stability; in order to further improve the assembly stability of the grass barrier, a support seat 117 that supports the frame is also formed on the back of the first baffle 11.
