At the same time, the belt 39 at the arc roller 37 drives the saw teeth 40 to fall into the gap between the arc stop 38 and the arc roller 37 under the action of gravity, and is driven to move in a direction close to the servo motor 3 under the resistance of the arc stop 38, and then the grass rope 9 is used to The positioning ring 8 and the plug sleeve 7 are installed on the turntable 5, and the grass is interrupted and cleaned with the grass-cutting rope 9, thereby eliminating the influence of the belt 39 and the saw teeth 40 on the grass-cutting work (such as the saw teeth 40, the telescopic end of the electric pole 34 and the belt 39 will push the grass to bend or get stuck on the saw teeth 40 during grass-cutting, affecting the grass-cutting work of the grass-cutting rope 9), thereby preventing the harder shrubs in the grass from hitting the grass-cutting rope 9 and causing the grass-cutting rope 9 to break, reducing the probability of damage to the grass-cutting rope 9, and improving the safety of the grass-cutting rope 9 and workers.

[0040] Specifically, a rotating rod 21 is installed through the inside of the L-plate 20, and the rotating rod 21 passes through the internal setting of the inclined wheel 22 and is rotatably connected to the inclined wheel 22. The sheath 63 can provide rotational support for the rubber wheel 19. The rubber wheel 19 and the inclined wheel 22 are made of rubber, which have large friction and can be slightly deformed. They will rebound after the external force disappears. The rotating rod 29 can provide a through channel for the connecting rod 42.

[0041] Drive parts include: A pressure ball 43 is fixed on a side of the pressure plate 44 away from the connecting rod 42; There are two springs 45, which are respectively arranged above the winding wheel 30 and the tray 23, one of which is sleeved on the outside of the connecting rod 42 and located between the pressure plate 44 and the winding wheel 30, and the other spring 45 is located between the pressure plate 44 and the tray 23; A linkage rod 46, one end of which is fixed to the outside of the support rod 35; The inclined pressure plate 47 is fixed to the other end of the linkage rod 46 and is located outside the pressure ball 43; The inclined arc plate 48 is fixed to one end of the inclined pressure plate 47 close to the linkage rod 46; The support column 49 is fixed to the outside of the sheath 63 by a fixing member and is adjacent to the bevel wheel 22 .

[0042] Specifically, the winding wheel 30 and the tray 23 can provide stable support for the spring 45, the spring 45 can provide support for the pressure plate 44, the pressure plate 44 can provide support for the connecting rod 42, so that the connecting rod 42 can provide support for the L plate 20, and the L plate 20 can provide support for the inclined wheel 22 through the rotating rod 21. The spring 45 can shrink and store energy under the action of external force, and will rebound after the external force disappears. The pressure plate 44 can stably support the pressure ball 43, and the pressure ball 43 is relatively smooth. The support rod 35 can stably support the linkage rod 46, and the linkage rod 46 can provide stable support for the inclined pressure plate 47. The inclined pressure plate 47 can provide support for the inclined arc plate 48. The inclined pressure plate 47 and the inclined arc plate 48 have curvature, which can fit with the pressure ball 43 and use external force to squeeze the pressure ball 43. The sheath 63 can use fixed components to stably support the support column 49.

[0043] The shovel set includes: A rubber wheel 50 is rotatably disposed on the outer side of the support column 49 and contacts the inclined wheel 22; The swivel post 51 is fixed to the end of the support post 49 away from the sheath 63; The magnet 53 is rotatably disposed on the outer side of the rotating column 51 and connected to the rubber wheel 50 through a connecting component; The storage cylinder 55 is fixed to the outside of the sheath 63 through a connecting member and is adjacent to the magnet 53; The shovel plate 57 is arranged on the inner side of the storage cylinder 55 and extends to the outer side of the magnet 53 and is close to the magnet 53; The arc guide plate 62 is symmetrically arranged on the outer side of the shovel plate 57 and is fixedly connected to the storage cylinder 55 .

[0044] Specifically, there is a gap between the rubber wheel 50 and the rubber ring 17, the support column 49 can provide stable support for the rotating column 51, and the support column 49 can provide rotational support for the rubber wheel 50. The rubber wheel 50 is made of rubber material and can be slightly deformed under the action of external force, and rebound after the external force disappears, and the friction force is relatively large. The outer side of the rotating column 51 is rotatably connected to the roller 52, and the magnet 53 is fixedly mounted on the outer side of the roller 52. The end of the storage tube 55 close to the magnet 53 is symmetrically fixed with a side block 56, and the side block 56 is located on the outer side of the magnet 53 and is fixedly connected to the arc guide plate 62. The end of the storage tube 55 away from the magnet 53 is installed with a cover plate 58 through a fixing component.

[0045] The rotating column 51 can provide rotation support for the roller 52, and the roller 52 can stably support the magnet 53. The servo motor 3 usually rotates clockwise, and then drives the turntable 5 and the rubber ring 17 to rotate clockwise together through the transmission shaft 4. The rubber ring 17 can use friction to push the rubber wheel 19 to rotate clockwise under the support of the sheath 63 when rotating clockwise, and the rubber wheel 19 can use friction to push the inclined wheel 22 in contact with it to rotate counterclockwise under the support of the rotating rod 21, and the inclined wheel 22 can use friction to push the rubber wheel 50 in contact with it to rotate clockwise. The rubber wheel 50 can drive the connecting plate 54 to rotate clockwise, and the connecting plate 54 can drive the roller 52 to rotate clockwise under the drive of the rubber wheel 50. The ends of the shovel plate 57 and the arc guide plate 62 close to the magnet 53 are sharper and have an inclination angle and an arc toward the storage cylinder 55. The gap between one end of the shovel plate 57 and the magnet 53 is 1-3mm. The shovel plate 57 and the arc guide plate 62 can shovel up the metal containing iron, cobalt and nickel adsorbed on the magnet 53, and provide a guiding effect for the shoveled metal adsorbed by the magnet 53 to enter the storage cylinder 55.

[0046] When the electric rod 34 is extended, the telescopic end of the electric rod 34 drives the linkage rod 46 to move in a direction away from the servo motor 3 through the support sleeve 41 and the support rod 35, and then the linkage rod 46 drives the inclined pressure plate 47 and the inclined arc plate 48 to move in a direction away from the servo motor 3. When the inclined pressure plate 47 and the inclined arc plate 48 move in a direction away from the servo motor 3 as the linkage rod 46 moves in a direction away from the servo motor 3, the inclined arc plate 48 and the inclined pressure plate 47 move along the pressure ball 43 and gradually press the pressure ball 43 downward by using their own inclination angle, so that the pressure ball 43 presses the pressure plate 44 downward by using external force, and then the pressure plate 44 presses the spring 45 downward under the action of external force, so that the spring 45 is squeezed and contracted and stores energy under the support of the winding wheel 30 and the tray 23, and at the same time, the pressure plate 44 drives the connecting rod 42 to move downward along the inner side of the rotating rod 29 through the tray 23, and then the connecting rod 42 drives the inclined wheel 22 to move downward through the rotating rod 21 and contacts the rubber ring 17 (such as Figure 5 As shown), when the pneumatic servo motor 3 drives the chassis 16 and the rubber ring 17 to rotate clockwise, the rubber ring 17 drives the rubber wheel 50 to rotate clockwise under the support of the support column 49 through the rubber wheel 19 and the inclined wheel 22, and then the rubber wheel 50 drives the roller 52 and the magnet 53 to rotate clockwise together through the connecting plate 54. Then, when the staff drives the mower to move on the grass through the handle 10, the side handle 11 and the machine rod 1, the rotating magnet 53 can use the magnetic force to absorb the metal objects containing iron, cobalt and nickel scattered in the grass.

[0047] When the magnet 53 absorbs the metal, it will use the rotational power and magnetic force to drive the metal object to approach the shovel plate 57 clockwise, so that the shovel plate 57 uses the reaction force and its own sharp end to shovel the metal object absorbed on the magnet 53, so that the metal object uses inertia to move to the shovel plate 57, and under the support and guidance of the shovel plate 57 and the arc guide plate 62 and the resistance of the side stop 56, it moves to the inside of the storage cylinder 55, so that the storage cylinder 55 can store the metal object, thereby making the grassland environment more environmentally friendly, and preventing the metal object and the grass rope 9 from hitting each other during the grass cutting work, thereby reducing the risk of the grass rope 9 breaking. After the metal object collection is completed and the shrub removal work is completed, the staff controls the electric rod 34 to retract, so that the electric rod 34 can drive the linkage rod 46 to move in the direction close to the servo motor 3 through the support rod 35, so that the linkage rod 46 can drive The movable inclined pressure plate 47 and the inclined arc plate 48 move together, so that the inclined pressure plate 47 and the inclined arc plate 48 move along the outer side of the pressure ball 43, and then the pressure ball 43 utilizes the inclination angle of the inclined pressure plate 47 and the inclined arc plate 48, and as the inclined pressure plate 47 and the inclined arc plate 48 follow the movement of the linkage rod 46, the squeezing force on the pressure ball 43 is gradually released, and then the spring 45 uses the rebound force to push the pressure plate 44 upward under the support of the tray 23 and the winding wheel 30, so that the pressure plate 44 uses the external force to push the pressure ball 43 upward, and at the same time, the pressure plate 44 will drive the connecting rod 42 to gradually move upward along the inner side of the rotating rod 29, so that the connecting rod 42 can use the external force to drive the inclined wheel 22 to move upward through the rotating rod 21, and then the inclined wheel 22 is separated from the rubber ring 17, and then the grass cutting rope 9 is connected to the rotating disk 5 and the servo motor 3 is started to carry out the grass cutting work.

[0048] Working principle: the servo motor 3 drives the turntable 5 to rotate through the transmission shaft 4, and the turntable 5 drives the mowing rope 9 to rotate together to cut the grass plants. The photovoltaic panel 14 on the power supply seat 13 converts solar energy into electrical energy, stores it in the battery 15, and supplies power to the power facilities of the mower, reducing the dependence on traditional electricity, and has significant energy-saving and environmental protection effects. The design of the baffle 2 and the protective part effectively prevents the mowing rope 9 from hitting the staff, thereby improving the safety of operation.

[0049] When the turntable 5 rotates, the chassis 16 drives the rubber ring 17 and the arc shovel plate 18 to rotate together. The arc shovel plate 18 uses its inclined angle and sharp end to cut off the roots of the grass to prevent the grass from regenerating, thereby reducing the workload of repeated mowing.

[0050] The electric rod 34 drives the supporting parts to move by telescoping, and the motor 33 drives the supporting wheel 31 to rotate. The supporting wheel 31 drives the saw teeth 40 of the belt 39 to rotate, so as to cut off the harder shrubs in the grass. The lawn mower can not only interrupt grass plants, but also cut off shrubs in the grass through the saw part, and collect metal objects through the iron collecting part. It has multiple functions and is suitable for different grassland environments.

[0051] When the servo motor 3 drives the turntable 5 to rotate, the rubber ring 17 drives the rubber wheel 19 and the inclined wheel 22 to rotate through friction, and the inclined wheel 22 drives the rubber wheel 50 and the magnet 53 to rotate. The magnet 53 absorbs the metal objects in the grass, and the shovel plate 57 shovels the metal objects into the storage tube 55 to prevent the metal objects from contacting the grass rope 9, reducing the risk of the grass rope 9 breaking, and further improving safety.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
