The clamping driver 807 is provided on the clamping claw 808, and the clamping driver 807 can drive the clamping claw 808 to realize the gathering and clamping of the straw. The baler 809 is provided on the first bracket 802, and the baler 809 is located on one side of the second bracket 803. The baling driver 810 is provided on the baler 809, and the baling driver 810 can drive the baler 809 to realize the packaging and bundling of the straw.
[0034] like Figure 11 and Figure 12 As shown, during operation, the rice harvester, which integrates harvesting and straw recovery, moves to a pre-designated harvesting location in the rice field. Upon reaching the designated location, the crop detection camera 105 detects signals indicating rice plant height and density and transmits this critical data to the control terminal in the form of a high-speed, stable signal. Upon receiving the signal, the control terminal accurately transmits the command to the cutting assembly 2.
[0035] like Figure 13As shown, the movable blade 202 and the fixed blade 203 in the cutting assembly 2 start to work together. The movable blade 202 moves back and forth under the drive of the cutting servo 204. The position and motion parameters of the movable blade 202 are adjusted in real time according to the instructions of the control terminal. With the cooperation of the movable blade 202 and the fixed blade 203, low stubble cutting is completed.
[0036] like Figures 13 to 15 As shown, the crop-supporting cylinder 304 in the rice-supporting assembly 3 is actuated, adjusting the position of the crop-supporting wheel 305 according to the height of the rice plants. The cut rice plants are then transferred to the conveyor belt 406 of the conveyor assembly 4 via the crop gathering assembly 104 on the traveling assembly 1. Driven by the first conveyor motor 402 and the second conveyor motor 403, the conveyor belt 406 transports the rice plants to the first separation assembly 5 at a stable speed. The drum motor 506 of the first separation assembly 5 begins to rotate at high speed, driving the separation gear 510 for efficient threshing. The shape and arrangement of the separation gear 510 ensures full contact with the rice plants, separating the rice grains from the straw through impact and friction. The first separation assembly 5 is also equipped with a concave screen 504. The rice grains and some impurities fall through the sieve holes of the concave screen 504, while the threshed straw and unseparated rice grains are transported to subsequent processing steps as the threshing gear 510 rotates.
[0037] like Figure 15 and Figure 16 As shown, the threshed straw and the unseparated rice then enter the second separation component 6. The filter screen surface 603 of the second separation component 6 is screened by the vibration mechanism composed of the first vibration connecting rod 606, the second vibration connecting rod 607 and the vibration motor 608 and the support spring 604. The support spring 604 plays a buffering and supporting role, and can automatically adjust its elasticity according to the vibration of the screen surface. The screened rice finally falls into the grain storage collection component 7. The grain storage guide plate 704 in the grain storage collection component 7 plays a guiding role, so that the rice is evenly distributed in the grain storage box 701, avoiding local accumulation. When the rice in the grain storage box 701 reaches the preset capacity, the grain storage air pump 702 starts working, generating gas to enable the grain storage push plate 705 to automatically unload the rice into the external container through the grain unloading port 706. At the same time, the separation baffle assembly on one side of the second separation assembly 6 moves, causing the grain baffle 614 at the third end of the filter screen 603 to move downward, so that the straw is collected in the separation guide plate 605. At this time, the straw processing assembly 8 is started to process the straw.
[0038] like Figures 17 to 19As shown, the first horizontal moving assembly 804, vertical moving assembly 805, and second horizontal moving assembly 806 are finally activated, driving the clamping claw 808 to the appropriate position. The clamping actuator 807 then drives the clamping claw 808 to precisely grasp the straw. The clamped straw is then transported to the baler 809, where the baler actuator 810 compresses the straw to form bales of a desired diameter. The compressed straw bales are then collected by the straw clamp and placed in the straw collection box 106. The rice harvester has now completed its rice harvesting and straw recovery operations.
[0039] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
