Detailed ways

The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

Referring to Figures 1 to 5, this embodiment discloses a multifunctional agricultural machinery vehicle for greenhouses, including a frame 1, and wheels 2 are provided at the bottom of the frame 1, including two front wheels and two rear wheels. A mechanical arm 3 is provided on the front side of the frame 1, and corresponding tools can be installed at the end of the mechanical arm 3 to perform operations such as picking and weeding. Radar systems 4 are provided on the frame 1 on the left and right sides of the mechanical arm 3, respectively, to provide obstacle avoidance and navigation functions for the movement of the mechanical vehicle. A storage box 5 is provided in the middle of the frame 1. A stubble planer 6 is provided on the rear side of the frame 1, and the body of the stubble planer 6 is connected to the frame 1 through a three-point suspension device, and the three-point suspension device includes a main motion mechanism 7 located on the left and right sides and a secondary motion mechanism 8 located in the middle.

The main motion mechanism 7 includes an upper connecting rod 9, a lifting rod 10, and a lower pull rod 11 which are hinged in sequence. The front end of the upper connecting rod 9 is hinged to the frame 1 through a first hinge shaft 12, and the rear end of the lower pull rod 11 is hinged to the frame 1 through a second hinge shaft 13. The upper connecting rod 9, the lifting rod 10, the lower pull rod 11 and the frame 1 constitute a four-bar mechanism. The lower pull rod 11 extends outward at the end away from the frame 1 to form a pull rod extension section 14. The left and right sides of the body of the stubble planer 6 are respectively hinged to the left and right pull rod extension sections 14 through mounting shafts 15. The upper connecting rod 9 is driven to flip around the first hinge shaft 12 by the main driving source, thereby driving the four-bar mechanism to move, and then driving the body of the stubble planer 6 to move through the two pull rod extension sections 14.

Among them, the main driving source is the main telescopic push rod 16, the fixed end of the main telescopic push rod 16 is hinged on the frame 1, and the movable end of the main telescopic push rod 16 is inclined backward and upward and hinged to the middle section of the upper connecting rod 9. The movable end of the main telescopic push rod 16 is extended and retracted, thereby driving the upper connecting rod 9 to flip around the first hinge axis 12.

The auxiliary motion mechanism 8 includes an auxiliary telescopic push rod 17, the fixed end of which is hinged on the frame 1, and the movable end of which is tilted upward and backward and hinged to the top of the body of the stubble planer 6, wherein a triangular frame 18 is provided on the top of the body of the stubble planer 6, and the movable end of the auxiliary telescopic push rod 17 is hinged to the top vertex of the triangular frame 18. The movable end of the auxiliary telescopic push rod 17 is extended and retracted, thereby driving the stubble planer 6 to swing around the axis of the two mounting shafts 15, so that the angle of the stubble planer 6 can be adjusted.

When working, the whole mechanical vehicle is driven to move by four wheels 2. Crops such as tomatoes, peppers, and strawberries can be picked or pesticides can be sprayed by tools installed at the end of the mechanical arm 3. When it is necessary to perform stubble-shaving operation at the root of crops, the angle of the stubble-shaving machine 6 is first adjusted by the auxiliary telescopic push rod 17; then the main telescopic push rods 16 of the main motion mechanism 7 on the left and right sides are telescopically moved to drive the respective upper connecting rods 9 to flip around the first hinge shaft 12, and the upper connecting rod 9 then drives the four-bar mechanism to move, driving the lower pull rod 11 to flip around the second hinge shaft 13, and then the fuselage of the stubble-shaving machine 6 is driven to move through the two pull rod extension sections 14, so as to realize the automatic stubble-shaving operation at the root of crops.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
