[0048] Example 1

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4This application provides a crop harvesting machinery device, including:

[0051] The frame 1 is composed of a load-bearing crossbeam 17, a vertical support rod 18, and an air pipe bracket 19. The vertical support rod 18 is connected to the load-bearing crossbeam 17 by welding, and the air pipe bracket 19 is connected to the vertical support rod 18 by welding. A crop divider 7 is fixed at the front end of the frame 1 and is deployed in front of the conveying device 2 along the direction of travel. It is used to guide the crops to the front end of the conveying device 2 and straighten the crops. Preferably, a protective cover 20 is covered on the outside of the frame.

[0052] The load-bearing crossbeam 17 of the frame 1 is also connected to a support wheel 5 and a drive wheel 6. The support wheel 5 is fixed to the frame 1 and is used to support the frame 1 in the air. The drive wheel 6 is fixed to the frame 1 and is used to support the frame 1 in the air and to provide driving power.

[0053] Conveying device 2, which is fixed to the frame 1, is used to fix and transport crops;

[0054] The conveying device 2 includes a first conveyor belt 12 and a second conveyor belt 13. The first conveyor belt 12 and the second conveyor belt 13 are arranged opposite to each other and have opposite transmission directions, and are used to clamp and convey crops. The front pulleys 14 of the first conveyor belt 12 and the second conveyor belt 13 are connected to the front pulley support plate 15 through a rotating joint. The front pulley support plate 15 is fixed to the frame 1 by bolts. The rear pulley support plate 16 is welded to the frame 1 and is connected to the rear pulley through a rotating joint.

[0055] Cutting device 3, which is fixed to the frame 1, is used to cut the crops fixed by the conveying device 2;

[0056] refer to Figure 5The cutting device 3 includes a cutting blade, which comprises a fixed blade 8 fixed to the frame 1 and a moving blade 9 fixed to the frame 1. When the moving blade 9 moves to a first moving position, it closes with the fixed blade 8 to cut the crop. When the moving blade 9 moves to a second moving position, it separates from the fixed blade 8 to facilitate crop entry. The moving blade 9 is driven by a cutting motor 10, which is bolted to the air pipe bracket of the frame 1. The cutting motor 10 drives the drive shaft 23 to rotate via a belt drive. The drive shaft 23 is connected to the drive shaft support frame 24 via a rotating joint. The drive shaft support frame 24 is bolted to the load-bearing crossbeam 17, driving the moving blade 9 to reciprocate, realizing the reciprocating motion between the first moving position and the second moving position. The first moving position is the position where the fixed blade 8 and the moving blade 9 are combined, and the second moving position is the position where the fixed blade 8 and the moving blade 9 are separated, thereby completing the cutting of the crop. In the cutting device 3, the fixed blade support plate 21 is connected to the load-bearing crossbeam 17 by welding. The fixed blade 8 is connected to the fixed blade support plate 21 by bolts. The moving blade support plate 22 is connected to the load-bearing crossbeam 17 by welding. One end of the moving blade 9 is connected to the force transmission plate 25 via a revolute joint, and the other end is connected via a slot. The force transmission plate 25 is connected to the connecting rod 26 via a revolute joint. The drive shaft 23 is connected to the connecting rod 26 via a revolute joint. A cutting drive motor 10 is used to drive the cutting blade to cut the crop.

[0057] Attitude adjustment device 4, fixed to the vehicle frame 1, includes:

[0058] A pneumatic assembly for applying a downward wind force to the crop to knock it down.

[0059] The pneumatic components include: a fan 11, which is fixed to the frame 1 and serves as a wind source; and one or more first air ducts 27, one end of which is connected to the fan 11, and the other end of which is used to provide wind power to the crop in a first direction through one or more air outlets.

[0060] The second air duct 28 has one end connected to the fan 11, and the other end provides a third-direction wind force to the crop through one or more air outlets. The third-direction wind force is horizontal, and the fourth direction is opposite to the third-direction wind force. The third air duct 29 has one end connected to the fan 11, and the other end provides a fourth-direction wind force to the crop through one or more air outlets. The fourth direction is opposite to the third-direction wind force. The second and third air ducts are located below the positioning and conveying assembly, and the one or more first air ducts are located above the positioning and conveying assembly. The attitude adjustment device stabilizes the lower end of the crop through the second and third air ducts 28 and 29. The first-direction wind force blown by the first air duct 27 blows the crop down, causing it to fall towards the positioning and conveying assembly. The positioning and conveying assembly further adjusts the crop's orientation, ensuring it falls horizontally.

[0061] refer to Figure 6 The system includes a positioning and conveying component for positioning crops and transporting them to a harvesting area. This ensures the crops maintain a consistent posture after harvest, facilitating subsequent manual bundling and improving operational efficiency. Furthermore, the positioning and conveying component can rotate under wind pressure, providing a second-direction resistance to the crops to ensure a slow descent and prevent damage. This second-direction resistance is opposite to the direction of the crops' descent.

[0062] The positioning and conveying assembly includes: a dial frame 30 fixed to the frame 1; a roller 31 rotatably mounted on the dial frame; and a claw 32 mounted on the roller to provide a second-direction resistance to the crop. The claw 32 has a curved structure, which allows the crop to descend slowly after contacting the positioning and conveying assembly, further reducing damage to the crop. When the crop enters the attitude adjustment device 4, its attitude is adjusted by the pneumatic components and the positioning and conveying assembly. The cutting device 3 and the attitude adjustment device 4 are deployed sequentially along the crop conveying trajectory.

[0063] Working principle:

[0064] In operation, the crop harvesting machinery is driven forward along the crop planting direction by the power wheel 6. The crop is guided to the front of the conveyor device 2 by the crop divider 7 fixed at the front of the frame 1, and the crop is straightened. The crop is then fixed and transported to the cutting device 3 by the first conveyor belt 12 and the second conveyor belt 13 of the conveyor device 2. The cutting motor 10 of the cutting device 3 drives the drive shaft 23 to rotate via belt drive. The rotation of the drive shaft 23 drives the moving blade 9 to reciprocate, realizing the separation and merging of the fixed blade 8 and the moving blade 9, thus completing the cutting of the crop. After the crop is cut, it enters the posture adjustment device. The fan 11, fixed to the frame 1, stabilizes the lower end of the crop through the second air duct 28 and the third air duct 29 of the posture adjustment device. The wind force from the first air duct 27 blows the upper leaves of the crop down, causing them to fall towards the positioning and conveying assembly. The positioning and conveying assembly uses the wind force from the first air duct 27 and the weight of the crop as its power source, causing the roller 31 to rotate and drive two claws to move in opposite directions. This fixes the fallen crop in one position before it falls, further rotating the curved structure of the claw 32 to adjust the crop's orientation, ensuring it falls horizontally. This achieves efficient crop harvesting and avoids the crop becoming disorganized after harvesting, improving the collection efficiency. It solves the technical problem in existing crop harvesting machinery where the disorganized posture of the harvested crop hinders efficiency improvement.
