Description

Technical Field

[0001] This utility model belongs to the field of agricultural harvester technology, specifically relating to a harvester with a freely combinable harvester assembly. Background Technology

[0002] Harvesters are indispensable production tools in agricultural production, suitable for large-scale crop cultivation in farmland. They can significantly save manpower and resources for harvesting crops, thereby improving production efficiency and economic benefits. Existing harvesters typically have their power unit fixed on the harvesting platform, transferring the harvested crop to the conveying mechanism. The harvesting platform and conveying mechanism are generally fixedly connected or integrated, resulting in a fixed structure that limits their application to harvesting only a single type of crop. In harvesters with detachable harvesting platforms, due to the unique structural positions of the various components, the harvesting platform is usually designed close to the ground, and the conveying mechanism is also positioned low, making installation more inconvenient. Utility Model Content

It develops a modular design for a shared chassis for rapeseed combined harvesting with a large feeding capacity. It innovatively designs a quick-connect electromechanical-hydraulic switch, a standardized quick interface, and a connection safety mechanism, enabling convenient assembly of the pickup platform and rapeseed / rice-wheat combined harvesting header with the shared chassis. This allows for the conversion between segmented and combined harvesting on a single set of equipment, enabling it to be used for both rapeseed, rice, and wheat harvesting, thus achieving multi-purpose functionality.

[0028] Combined with appendix Figures 1 to 11As shown, this embodiment discloses a harvester with a freely combinable harvesting platform assembly, including a harvester body 1, a feeding mechanism 2, and a harvesting mechanism 3. The feeding mechanism 2 includes a feeding pipe 21 and a lifting part 22. The harvesting mechanism 3 harvests crops and feeds them into the feeding pipe 21. The lifting part 22 includes a connecting plate 221, a drive part 222, and at least one reinforcing rod 223. Preferably, in this embodiment, two reinforcing rods 223 are provided on each of the left and right sides of the feeding pipe 21 to improve the structural strength and stability of the lifting part 22. The drive part 222 is a hydraulic cylinder. In other embodiments, commonly used hydraulic cylinders in the prior art can also be used. Other driving devices; one end of the driving unit 222 is hinged to the harvester body 1, and the other end is hinged to one end of the reinforcing rod 223. The other end of the reinforcing rod 223 is hinged to the conveying pipe 21. The connecting plate 221 is fixedly mounted on the conveying pipe 21 by fasteners 23 and is fixedly connected to one end of the reinforcing rod 223, so that the driving unit 222 drives the conveying pipe 21 to rise and fall. The harvester body 1 includes a driving transmission mechanism 11, which includes a transmission part 111. The harvesting mechanism 3 is detachably connected to the harvester body 1 through the transmission part 111 and detachably connected to the conveying mechanism 2 through the lifting part 22.

[0029] In conjunction with the above, the main body 1 of the harvester also includes other structures commonly found in harvesters in the prior art, such as the driver's cab and the frame; the material conveying mechanism 2 also includes material conveying structures commonly used in harvesters in the prior art, such as the threshing mechanism and the screening mechanism; the fasteners 23 adopt fastening components commonly used in the prior art, such as bolts; preferably, the transmission part 111 adopts a belt.

[0030] Based on the above installation structure, the working process of the lifting unit 22 is as follows: When it is necessary to disassemble or install the harvesting mechanism 3, the drive unit 222 is a hydraulic cylinder. The telescopic rod of the hydraulic cylinder extends. Since the end of the telescopic rod is hinged to the end of the reinforcing rod 223, and the other end of the reinforcing rod 223 is hinged to the side of the conveying pipe 21, the end hinged to the telescopic rod is raised upward. Since the reinforcing rod 223 is fixedly connected to the connecting plate 221, the connecting plate 221 is raised upward. The connecting plate 221 is fixedly connected to the inlet of the conveying pipe 21, so that the height of the conveying pipe 21 is raised, thereby facilitating the disassembly and assembly of the harvesting mechanism 3 by the operators.

[0031] In conjunction with the above, the harvesting mechanism 3 includes a first connecting part 32. Preferably, in this embodiment, the first connecting part 32 is a pulley. The first connecting part 32 and the transmission part 111 are matched and arranged to each other. The drive transmission mechanism 11 transmits power to the transmission part 11 and the first connecting part 32, and the first connecting part 32 transmits power to the harvesting mechanism 3.

[0032] In conjunction with the above, the harvesting mechanism 3 also includes a second connecting part 33, which includes a plurality of connecting seats 331. The connecting seats 331 are matched and connected to the connecting plate 221 and the conveying pipe 21 through fasteners 23, thereby realizing the detachable connection between the harvesting mechanism 3 and the conveying mechanism 2.

[0033] In conjunction with the above, the harvesting mechanism 3 also includes a harvesting table 31, and the first connecting part 32 can transmit power from the drive transmission mechanism 11 to the harvesting table 31 so that the harvesting table 31 can work.

[0034] Based on the above installation structure, harvesting platforms 31 with different structures can be adopted according to the different types of crops to be harvested and the different uses required in actual application scenarios. Several preferred embodiments of harvesting platforms 31 are listed below. Example

[0035] Based on Example 1, combined with Figure 8 As shown, the harvesting platform 31 is a rice and wheat harvesting platform.

The reel 311 is equipped with several metal rods to push the rice and wheat towards the cutting section 312. After the cutting section 312 cuts the rice and wheat, the auger 313 sends them into the conveying pipe 21. The divider 314 is used to separate the crops inside and outside the cutting section 312. Example

[0036] Based on Example 1, combined with Figure 9 As shown, the harvesting platform 31 is a rapeseed harvesting platform. The rapeseed harvesting platform includes a reel 311, a cutting section 312, and an auger 313. The reel 311 is equipped with several metal rods to push the rapeseed towards the cutting section 312. After the cutting section 312 cuts the rapeseed, it is fed into the conveying pipe 21 by the auger 313. Example

[0037] Based on Example 1, combined with Figure 10 As shown, the harvesting platform 31 is a rapeseed harvesting and drying platform. The rapeseed harvesting and drying platform includes a reel 311, a cutting section 312, and a drying platform 315. The reel 311 is equipped with several metal rods to push the rapeseed towards the cutting section 312. After the cutting section 312 cuts the rapeseed, it is sent to the drying platform 315 for drying. Example

[0038] Based on Example 1, combined with Figure 11 As shown, the harvesting platform 31 is a rapeseed picking platform. The rapeseed picking platform includes a picking wheel 316 and an auger 313. The picking wheel 316 includes several metal rods for picking up rapeseed and feeding it into the auger 313, which then feeds the rapeseed into the conveying pipe 21.
