When the cushion pad 8 contacts the guardrail, the guide wheels 16 in the grooves 15 of the cushion pad 8 can guide and facilitate the rotation of the protective shell 3. When blade 4 cutting green back of planting, the branch and leaf of green planting can block easily between baffle 7 and protecting crust 3, promote slide bar 19 and rectangular plate 18 in the spout 17 this moment, make rectangular plate 18 take dead lever 20 and inserted bar 21 to remove, the branch and leaf in the spout 17 is scraped down to dead lever 20, curved inserted bar 21 plays clean baffle 7 and the effect between the protecting crust 3 simultaneously, and then reduce the existence branch and leaf between protecting crust 3 and the baffle 7, thereby influence the normal slip of baffle 7, and baffle 7 when sliding the shrink to protecting crust 3 direction, can slide bar 19 to rectangular plate 18, and then realize the removal of baffle 7. When the fixing rod 20 slides, the swinging rod 23 and the impact ball 24 made of the magnet material can be driven to slide together, when the impact ball 24 touches the first magnet 25, the impact ball can be bounced off due to the principle that like poles repel each other, and the swinging rod 23 is connected through the torsion spring, so that the swinging rod 23 can reset after leaving the first magnet 25, at the moment, the impact ball 24 is close to the second magnet 26 and used for keeping away the impact ball 24 and the second magnet 26 from opposite poles, the impact ball 24 and the second magnet 26 attract each other to impact each other, and then vibration is generated, so that the effect of assisting in cleaning the inner wall of the chute 17 is achieved, and foreign matters adhered to the inner wall of the chute 17 are cleaned. When the sliding block 5 slides in the accommodating groove 36, the hollow elastic block 27 in the accommodating groove 36 is extruded, so that the gas in the elastic block 27 is blown out through the gas guide pipe 28, and then the rectangular plate 18 is blown, and the rectangular plate 18 drives the sliding rod 19 to slide in the sliding groove 17, so that the sliding of the rectangular plate 18 can be realized without manually pushing the rectangular plate 18, and the rectangular plate 18 is enabled to realize the cleaning effect. The pressing plate 29 and the blocking piece 30 are arc-shaped, so that the elastic block 27 can be better extruded, and after the elastic block 27 is extruded by the pressing plate 29 to deform, the blocking piece 30 can make up the gap between the elastic block 27 and the accommodating groove 36, so that the elastic block 27 can be better extruded by the pressing plate 29. When the air duct 28 sprays gas, the gas can be influenced by the inclined guide plate 31, so that the gas is gathered between the air duct 28, the pressure of the gas is enhanced, and meanwhile, the flow guide effect is formed, so that the gas can conveniently push the rectangular plate 18. When gaseous process guide plate 31, can blow connecting plate 32 for connecting plate 32 blows to the port department of air guide pipe 28, and then makes the connecting plate 32 of magnet material and the rectangular plate 18 like poles of the same polarity of magnet material repel each other, and the supplementary rectangular plate 18 that slides, because the both ends of connecting plate 32 are the rubber material, and then can produce deformation and slide, and gaseous can blow out through connecting plate 32.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
