[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The present invention is further described in detail below in conjunction with the embodiments.

[0022] A specific embodiment of a bean harvester provided by the utility model:

[0023] like Figure 1-3 As shown, the bean harvester comprises an engine and a harvester frame 1, a suspension frame 2 is installed on the front side of the harvester frame 1, a lifting hydraulic cylinder 3 is installed between the suspension frame 2 and the harvester frame 1, and the lifting hydraulic cylinder 3 is used for lifting the suspension frame 2, two ground wheel assemblies 4 and two seedling separators are installed on the front side of the suspension frame 2, and a crossbeam 5 is also arranged on the suspension frame 2, and a bean cutting mechanism is arranged on the crossbeam 5, and the bean cutting mechanism is mainly used for harvesting bean plants;

[0024] The bean cutting mechanism includes a power shaft 6 and two groups of bean cutting assemblies. The bean cutting assembly includes a gear box 7. The gear box 7 is arranged on the crossbeam 5. An outer sleeve 8 is fixed to the bottom of the gear box 7. A rotating shaft 9 is arranged in the outer sleeve 8. A bean cutting disc 10 is fixed after the lower end of the rotating shaft 9 extends downward from the outer sleeve 8. A gear transmission component is arranged in the gear box 7. The bean cutting discs 10 of the two groups of cutting table assemblies rotate in opposite directions.

[0025] The power shaft 6 is passed through the gear boxes 7 of the two bean cutting assemblies, and the power shaft 6 is connected to the upper end of the rotating shaft 9 through a gear transmission component, and the engine is connected to the end of the power shaft 6 by transmission, and the transmission connection method can be a transmission belt, gear transmission, etc.

[0026] When the bean harvester of this embodiment is in operation, the engine serves as a power source to drive the harvester frame 1 to move, the lifting hydraulic cylinder 3 extends to make the suspension frame 2 fall, the ground wheel assembly 4 contacts the ground, and the engine also drives the power shaft 6 to rotate, and the power shaft 6 can drive the rotating shaft 9 to rotate through the gear transmission assembly. Driven by the rotating shaft 9, the bean cutting knife disc 10 rotates at high speed; as the harvester frame 1 moves forward, the two groups of seedling devices separate the bean plants in the ridge, and then the bean plants enter the area between the two bean cutting knife discs 10, and the two bean cutting knife discs 10 rotate in convection, cut the bean plants and throw them backwards.

[0027] In addition, since the ridge distances of different bean plants are different, the above-mentioned cutting platform mechanism can be further optimized to adjust the distance between the two sets of bean cutting blades 10. Specifically: the left and right sides of the gear box 7 are respectively suspended and installed on the crossbeam 5 by U-bolts 11; the power shaft 6 is a spline shaft, and the gear transmission assembly includes a spline sleeve 100, a first bevel gear 12 and a second bevel gear 13. The spline sleeve 100 is fixed in the gear box 7, the power shaft 6 passes through the spline sleeve 100, the first bevel gear 12 is installed on the spline sleeve 100, and the second bevel gear 13 is arranged at the upper end of the rotating shaft 9, and the first bevel gear 12 is meshed with the second bevel gear 13.

[0028] When the distance between the two sets of bean cutting blades 10 needs to be adjusted, the U-bolt 11 is loosened, and then the gear box 7 is manually pushed. Since the power shaft 6 is inserted into the spline sleeve 100, the gear box 7 can be moved on the power shaft 6 by pushing it. When it moves to a suitable position, the nut on the U-bolt 11 is tightened to fix the gear box 7 again; the power shaft 6 drives the first bevel gear 12 to rotate, and the first bevel gear 12 is meshed with the second bevel gear 13 for transmission, and finally drives the rotating shaft 9 to rotate; in addition, it should be noted that if Figure 3 As shown, the first bevel gears 12 in the two sets of gear boxes 7 are installed in opposite directions to ensure that the two rotating shafts 9 rotate in opposite directions and the bean cutting blades 10 rotate in opposite directions.

[0029] The above device can also be further optimized, for example, Figure 4As shown, the ground wheel assembly 4 includes a vertical circular tube 14 and a screw rod 15. The vertical circular tube 14 is fixed on the suspension frame 2. A threaded inner sleeve 16 is rotatably installed in the vertical circular tube 14. An end cover 17 is fixed to the upper end of the vertical circular tube 14. A crank 18 is passed through the end cover 17. The lower end of the crank 18 passes through the end cover 17 and is fixed to the upper end of the threaded inner sleeve 16. The threaded inner sleeve 16 has an internal thread. The upper thread of the screw rod 15 is installed in the threaded inner sleeve 16. The lower end of the screw rod 15 is installed with a ground wheel 19. Shaking the crank 18 drives the threaded inner sleeve 16 to rotate, and the threaded inner sleeve 16 is threadedly matched with the screw rod 15. The rotation of the threaded inner sleeve 16 will inevitably drive the screw rod 15 to move up and down. The ground wheel 19 is set at the lower end of the screw rod 15. When the screw rod 15 is raised or lowered, the height of the suspension frame 2 relative to the ground wheel 19 changes, and finally changes the height of the bean cutting knife disk 10, that is, the depth of the bean cutting knife disk 10 as shown in the figure. According to the conditions of different bean plants, the depth of the bean cutting knife disk 10 is adjusted.

[0030] like Figure 1 and Figure 5 As shown, the seedling separator of this embodiment includes an oblique square tube 20, a connecting rod 21 is arranged between the oblique square tube 20 and the vertical circular tube 14, the two ends of the connecting rod 21 are respectively connected to the oblique square tube 20 and the vertical circular tube 14 by a hinged manner, two seedling separators 22 are arranged on the oblique square tube 20, a pull rod 23 is fixed to the upper end of the oblique square tube 20, a guide sleeve 24 is fixed to the front side of the upper end of the vertical circular tube 14 through a connecting rod, the guide sleeve 24 is arranged obliquely, the pull rod 23 is upwardly inserted into the guide sleeve 24, the upper part of the pull rod 23 has an external thread, the upper part of the pull rod 23 is provided with an adjusting nut 25 and a spring 26, the two ends of the spring 26 are in contact between the upper end of the guide sleeve 24 and the adjusting nut 25.

[0031] During operation, the bottoms of the two seedling separation boards 22 are in contact with the ground. As the land rises and falls, the seedling separation boards 22 can float up and down. Specifically, the seedling separation boards 22 are installed on the oblique square tube 20, and the oblique square tube 20 is connected to the vertical circular tube 14 through a connecting rod 21. When the oblique square tube 20 moves upward, the connecting rod 21 swings, the pull rod 23 moves upward, and the spring 26 stretches. When the oblique square tube 20 moves downward, the pull rod 23 pulls the spring 26 to compress, thereby finally realizing the up and down floating of the oblique square tube 20 and the seedling separation boards 22.

[0032] Preferably, a hook 27 can be provided at the lower end of the seedling divider, and the hook 27 is used to lift up the fallen bean plants; two guide plates 28 are fixed on the hanging frame 2, and the two guide plates 28 are located between the seedling divider and the bean cutting knife disk 10, and the guide plates 28 are used to guide the bean plants through the seedling divider to the bean cutting knife disk 10.

[0033] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
