Description

Technical Field

[0001] This utility model belongs to the field of regenerated rice harvesting technology, specifically relating to a regenerated rice harvester. Background Technology

[0002] Ratoon rice is produced by harvesting about two-thirds of the rice plant after the first crop has matured, collecting the panicles, and leaving the bottom third of the plant and its root system. This bottom third of the plant is then fertilized and nurtured to allow it to sprout again, grow panicles, flower, and bear fruit, producing another crop of rice. Because it grows again on its original root system, ratoon rice can be harvested after about two months.

[0003] After the first crop of rice matures, to preserve one-third of the rice stubble and root system, it can only be harvested using traditional rice harvesting methods. However, traditional harvesting relies on manual labor, which is inefficient and typically takes a long time—sometimes several days, sometimes over a month—and is only possible on sunny or dry days, further reducing efficiency. Once rice regrows from the preserved one-third of the stubble, since there's no need to retain the stubble, a combine harvester can be used to harvest the ratooning rice. This significantly improves harvesting efficiency, ensuring the ratooning rice is harvested quickly. However, some existing combine harvesters have complex structures, making them difficult to manufacture. Furthermore, after harvesting the ratooning rice, the harvester discharges the stubble back into the paddy field, often leaving rice grains on the stubble, indicating incomplete threshing and wasting rice.

[0041] Example 1

[0042] like Figure 1-18 As shown, the present invention provides a regenerated rice harvester, including a regenerated rice cutting mechanism suspended on an external walking device, a regenerated rice conveying mechanism inclined on the external walking device and connected to the regenerated rice cutting mechanism, a regenerated rice threshing mechanism on the external walking device and connected to the regenerated rice conveying mechanism, and a rice straw recycling mechanism and a rice grain receiving mechanism respectively on the external walking device and respectively connected to the regenerated rice threshing mechanism.

[0043] This utility model has a simple structure, a scientific and reasonable design, is easy to use, and is convenient to manufacture. This utility model uses a double threshing drum to thresh the ratooned rice. The threshing blocks on the threshing drum beat and crush the ratooned rice, removing the rice grains from the rice stalks, which improves the threshing strength of the ratooned rice and reduces the amount of rice grains remaining on the rice stalks. At the same time, this utility model collects the rice stalks after threshing, so that the rice stalks can be manually fed into the threshing box for threshing again, so that the rice grains remaining on the rice stalks are removed from the rice stalks, thereby making the ratooned rice threshed completely and avoiding rice waste.

[0044] In use, this utility model is propelled forward by an external walking device. During this movement, two sorting plates 20 on the cutting table 19 separate the unharvested ratooning rice from other ratooning rice, gathering the unharvested ratooning rice between the two sorting plates 20. The reel 22 rotates, pushing the unharvested ratooning rice between the two sorting plates 20 to the cutter 21. The cutter 21 cuts the ratooning rice off the ground. The auger 23 guides the cut ratooning rice into the cutting table 19. The telescopic claw 24 pulls the ratooning rice inside the cutting table 19 onto the conveyor belt 2. The conveyor belt 2 transports the ratooning rice to the position where the threshing box 3 is connected to the transmission housing 1. Inside the threshing box 3, the threshing drum 4 rotates and winds the ratooning rice onto the threshing screen 5. The threshing blocks 35 on the threshing drum 4 beat and crush the ratooning rice on the threshing screen 5, causing the rice grains to separate from the rice stalks and be threshed. As the drum 4 continues to rotate, the threshing blocks 35 on the threshing drum 4 simultaneously push the threshed rice straw backward, so that the rice straw is transferred to the end of the threshing screen plate 5 near the rice straw outlet 8. The rice straw falls into the recycling box 14 through the rice straw outlet 8 at the end of the threshing screen plate 5 near the rice straw outlet 8. During the process of the threshing blocks 35 beating and crushing the regenerated rice on the threshing screen plate 5, the threshing screen plate 5 vibrates. The rice on the threshing screen plate 5 falls onto the first conveyor plate 6 through the first screen hole 59 on the threshing screen plate 5. The rice rolls down on the first conveyor plate 6 and falls onto the second conveyor plate 10 through the rice grain outlet 7. The rice continues to roll down on the second conveyor plate 10 until it falls onto the lifting belt conveyor 11. Under the lifting action of the lifting belt conveyor 11, it is conveyed to the top of the silo 12 and enters the silo 12 through the inlet 13 at the top of the silo 12. The rice straw collected in the recycling bin 14 is manually fed into the threshing bin 3 through the feeding inlet 18. The threshing roller 4 in the threshing bin 3 threshes the rice straw again, so that the rice grains remaining on the rice straw are separated from the rice straw and the regenerated rice is completely separated. In this way, rice waste can be avoided.

[0045] As the rice grains fall from the first conveyor plate 6 to the second conveyor plate 10, the blower blows air onto the falling rice grains, causing impurities such as rice leaf fragments mixed in with the rice grains to separate from the rice grains under the action of the wind. The rice leaf fragments and other impurities are discharged to the outside, and the rice grains fall from the first conveyor plate 6 onto the second conveyor plate 10.

[0046] External mobility equipment can be external tracked vehicles.

A second drive motor 38 connected to the active roller 36 is provided on the outer wall of the transmission housing 1.

[0052] The principle of conveyor belt 2 conveying ratooned rice is as follows: the second drive motor 38 starts, the second drive motor 38 drives the drive shaft to rotate the active roller 36, the active roller 36 drives the conveyor belt 2 to move back and forth between the active roller 36 and the driven roller 37, and the back and forth moving conveyor belt 2 continuously conveys the ratooned rice pulled by the telescopic claw 24 to the threshing box 3.

[0055] The ratooning rice conveying mechanism includes a conveying housing 1 inclined on an external walking device, and a conveyor belt 2 disposed inside the conveying housing 1; the conveyor belt 2 is connected from the ratooning rice cutting mechanism and connected to the ratooning rice threshing mechanism.

The threshing box 3 is equipped with a third drive motor 40 connected to the threshing drum 4. A first sprocket B41 is connected to the drive shaft of the third drive motor 40, and a second sprocket B42 is provided on the shaft 39. A third chain 43 meshes between the first sprocket B41 and the second sprocket B42.

[0058] The principle of the rotation of the threshing drum 4 is as follows: the third drive motor 40 starts, the drive shaft of the third drive motor 40 drives the first sprocket B41 to rotate, the first sprocket B41 drives the third chain 43 to move, the third chain 43 drives the second sprocket B42 to rotate, the second sprocket B42 drives the shaft 39 to rotate, and the shaft 39 drives the threshing drum 4 to rotate.

[0059] The principle of threshing ratoon rice in the threshing box 3 is as follows: The ratoon rice conveying mechanism transports the ratoon rice to the inlet of the threshing box 3. The threshing drum 4 inside the threshing box 3 rotates and winds the ratoon rice onto the threshing screen plate 5. The threshing blocks 35 on the threshing drum 4 beat and crush the ratoon rice on the threshing screen plate 5, causing the rice grains to separate from the rice stalks. The threshing drum 4 continues to rotate, and the threshing blocks 35 on the threshing drum 4 simultaneously push the threshed rice stalks backward, so that the rice stalks are transported to the end of the threshing screen plate 5 near the rice stalk outlet 8. The rice stalks fall into the recycling box 14 through the rice stalk outlet 8 at the end of the threshing screen plate 5 near the rice stalk outlet 8. During the process of beating and crushing the ratoon rice on the threshing screen plate 5 by the threshing blocks 35, the threshing screen plate 5 vibrates, and the rice grains on the threshing screen plate 5 fall onto the first conveying plate 6 through the first screen hole 59 on the threshing screen plate 5.

[0060] The rice grains roll downwards on the first conveyor plate 6 and fall through the rice grain outlet 7 onto the second conveyor plate 10. The rice grains continue rolling downwards on the second conveyor plate 10 until they fall onto the lifting conveyor belt 11. Under the lifting action of the lifting conveyor belt 11, they are conveyed to the top of the silo 12 and enter the silo 12 through the inlet 13 at the top of the silo 12. During the process of the rice grains falling from the first conveyor plate 6 onto the second conveyor plate 10, the blower 9 blows air onto the falling rice grains, causing impurities such as rice leaf fragments mixed in with the rice grains to separate from the rice grains under the action of the airflow. The rice leaf fragments and other impurities are discharged to the outside, while the rice grains fall from the first conveyor plate 6 onto the second conveyor plate 10.

[0061] A sliding plate 44 is provided between the threshing box 3 and the recycling box 14. The recycling box 14 has a rice straw inlet 45 that communicates with the inside of the recycling box 14.
