[0024] The embodiment of the utility model provides a modified harvesting platform suitable for a soybean harvester in hilly and mountainous areas.

[0025] See also Figure 1 , including a header body 1, a power supply is installed inside the header body 1, which can supply power to the electrical equipment in this application.

[0026] Please refer again Figure 1 、 Figure 2 and Figure 3 The inner wall of the cutting platform body 1 is rotatably connected to the conveying roller 2, and the outer surface of the cutting platform body 1 is provided with a discharge port. By turning on the driving device to drive the conveying roller 2 to rotate, the soybean straw inside the cutting platform body 1 can be effectively transported to the discharge port, so that the soybeans can enter the next process.

[0027] A rice pulling mechanism 3 is provided on the outside of the harvesting platform body 1. The rice pulling mechanism 3 includes a swing rod 301. One end of the swing rod 301 is hinged with an adjustment box 302. The inner wall of the adjustment box 302 is rotatably connected to the conveyor roller 2 through a bearing. By driving the swing rod 301 to swing, the adjustment box 302 can be driven to rotate with the conveyor roller 2 as the axis. The outer ring of the bearing between the conveyor roller 2 and the adjustment box 302 is fixedly connected to the adjustment box 302, and the inner ring of the bearing is fixedly connected to the conveyor roller 2. Through the setting of the bearing, the rotation of the adjustment box 302 will not be affected by the rotation of the conveyor roller 2.

[0028] The inner wall of the adjustment box 302 is rotatably connected to the driven shaft 303 through a bearing, the outer surface of the driven shaft 303 is fixedly connected to the plucking roller 304, and the outer surface of the plucking roller 304 is fixedly connected to the plucking teeth 305. By driving the plucking teeth 305 to rotate, the height of the plucking teeth 305 can be adjusted individually, so that the plucking teeth 305 can be used to plucking soybean straw in uneven rice fields in hilly and mountainous areas.

[0029] The end of the swing rod 301 away from the adjustment box 302 is hinged with a threaded slider 306, and the outer surface of the threaded slider 306 is slidably connected to the fixed slide box 307. The outer surface of the fixed slide box 307 is fixedly connected to the cutting platform body 1. Through the setting of the fixed slide box 307, the threaded slider 306 is provided with a limiting support, so that the adjusting screw 311 drives the threaded slider 306 to move with greater stability.

[0030] The outer surface of the cutting platform body 1 is rotatably connected to the driving sprocket 308, and the outer surface of the driving sprocket 308 is transmission-connected to the chain 1 309. A driving motor is installed inside the cutting platform body 1, and the output end of the driving motor is fixedly connected to the driving sprocket 308, so that when the motor is turned on, the driving sprocket 308 can be driven to drive the chain 1 309 for transmission.

[0031] The outer surface of the chain 309 is transmission-connected to the driven sprocket 310, and the outer surface of the driven sprocket 310 is fixedly connected to the adjusting screw 311. The outer surface of the adjusting screw 311 is rotationally connected to the fixed slide box 307, and the outer surface of the adjusting screw 311 is threadedly connected to the threaded slider 306. By rotating the driven sprocket 310, the threaded slider 306 on the surface of the adjusting screw 311 can be driven to slide left and right in the inner wall of the fixed slide box 307, thereby driving the swing rod 301 to swing to adjust the adjusting box 302.

[0032] One end of the conveying roller 2 and the driven shaft 303 are fixedly connected to the driven sprocket 2 312, and the outer surfaces of the two driven sprockets 2 312 are transmission-connected with the chain 2 313. Through the linkage setting of the driven sprocket 2 312 and the chain 2 313, when the conveying roller 2 is driven to rotate, the pulling roller 304 can be driven to rotate at the same time to pull the soybean straw.

[0033] Please refer again Figure 1 and Figure 4 A cutting mechanism 4 is provided on the outside of the cutting platform body 1, and the cutting mechanism 4 includes a straw divider 401. The outer surface of the straw divider 401 is fixedly connected to the cutting platform body 1. Through the setting of the straw divider 401, the dumped soybean straw can be divided into multiple groups, thereby facilitating the cutting of the cutting knife body 402.

[0034] The inner wall of the straw divider 401 is slidably connected to the cutting knife body 402, and the outer surface of the cutting knife body 402 is slidably connected to the cutting platform body 1. The soybean straw is fixed by the left and right reciprocating movement of the cutting knife body 402 in conjunction with the straw divider 401, so that the straw can be cut quickly, further making the device more practical.

[0035] The driving device and driving motor mentioned in this application are both common electrical devices in the prior art. This application will not go into too much detail about their models or internal structures, and they can also be replaced by other power sources.

[0036] When the utility model is in use: first, the active sprocket 308 is driven to rotate according to the requirements of harvesting, and the rotation of the active sprocket 308 cooperates with the transmission of the chain 1 309, so that the two driven sprockets 1 310 can rotate at the same time, and the rotation of the driven sprocket 1 310 drives the adjusting screw 311 to rotate, and the rotation of the adjusting screw 311 drives the threaded slider 306 to slide left and right in the inner wall of the fixed slide box 307, and the sliding of the threaded slider 306 drives the swing rod 301 to swing, and the swing rod 301 swings and drives the adjusting box 302 to rotate with the conveying roller 2 as the axis, and the rotation of the adjusting box 302 drives the driven shaft 303 in its inner wall to rotate, so that the plucking height of the plucking teeth 305 on the surface of the plucking roller 304 can be effectively adjusted separately, which is convenient for plucking soybean straw in uneven rice fields in hilly and mountainous areas. Secondly, the driving device inside the harvesting platform body 1 is turned on to drive the conveying roller 2 to rotate, and at the same time drive the cutting knife body 402 to slide horizontally back and forth in the inner wall of the straw divider 401. The rotation of the conveying roller 2 cooperates with the setting of the driven sprocket 2 312 and the chain 2 313, so as to drive the driven shaft 303 to rotate at the same time. The rotation of the driven shaft 303 drives the straw pulling teeth 305 on the surface of the straw pulling roller 304 to rotate to pull the soybean straw, so that the soybean straw is dumped as a whole into the interior of the harvesting platform body 1. At this time, the dumped soybean straw is separated by the straw divider 401, so that the cutting knife body 402 can quickly cut the straw during movement, effectively avoiding the situation where the straw falls from the front of the harvesting platform body 1 to the ground during cutting, causing harvesting losses, and further improving the harvesting efficiency of the device.
