Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, an anti-collision shell of a mower comprises a mower body 1, a shell 2, four anti-collision plates 4 and a top cover 19, wherein a handrail 3 is fixed on the top of the mower body 1, the shell 2 covers the mower body 1, the top cover 19 is fixed on the top of the shell 2, a fixing ring 20 is fixed on the bottom surface of the top cover 19, a plurality of mounting holes 21 are formed in the outer wall of the shell 2, bolts 22 are rotatably connected to the inside of the mounting holes 21, one ends of the bolts 22 extend to the inside of the shell 2 and are in threaded connection with the fixing ring 20, the top cover 19 and the shell 2 are separately installed and are convenient to assemble, a connecting groove 9 is formed in the top of the top cover 19, one end of the handrail 3 penetrates through the connecting groove 9 and extends to the outside of the shell 2, and the top cover 19 is fixed on.

All be fixed with two fixed plates 14 on the both sides inner wall of shell 2, the bottom surface of fixed plate 14 is fixed with screw post 13, two connecting holes 15 have all been seted up to lawn mower body 1's top both sides, four fixed plates 14 respectively with the top surface contact of lawn mower body 1, four screw post 13's bottom runs through four connecting holes 15 respectively and extends to lawn mower body 1's outside, pass through nut 16 fixed connection between screw post 13 and the lawn mower body 1, through connecting hole 15, the screw post, the cooperation between fixed plate 14 and the nut, reach the purpose of conveniently fixing shell 2 and lawn mower body 1.

The outer walls of four sides of the shell 2 are respectively provided with a sliding chute 6, the inner parts of the two sliding chutes 6 are respectively fixed with a fixed column 23, the outer part of the fixed column 23 is respectively sheathed with two sliding blocks 7 and two springs, the two springs are respectively positioned at one side of the two sliding blocks 7 which are far away from each other, the back surfaces of the four anti-collision plates 4 are respectively articulated with two connecting rods 8, the four anti-collision plates 4 are respectively positioned in four volumes of the shell 2, and two connecting rods 8 on any one anti-collision plate 4 are respectively hinged with two sliding blocks 7 on one fixed column 23, the connecting rods 8 and the anti-collision plate 4 are obliquely arranged, when the anti-collision plate 4 is impacted, the connecting rod 8 can move obliquely, so that the sliding block 7 is driven to slide on the fixed column 23, the spring is compressed, under the effect of spring, the impact is converted into the elasticity of spring, and then the extension through the spring is released away to great power of slowing down the striking.

The bottom of slider 7 is fixed with stopper 18, and spacing groove 17 has been seted up to the bottom surface of spout 6, and the one end of stopper 18 extends to inside and the spacing groove 17 sliding connection of spacing groove 17, and the cooperation between stopper 18 and the spacing groove can avoid slider 7 to take place to rotate when removing.
