Description

Technical Field

[0001] The invention belongs to the technical field of regenerated rice harvesting, and in particular relates to a regenerated rice harvester. Background Art

[0002] Ratoon rice is when one season of rice matures, only about 2 / 3 of the rice plant is cut off to collect the rice ears, leaving the lower 1 / 3 of the plant and the root system, fertilizing and nurturing, so that the remaining 1 / 3 of the plant can sprout again, grow ears, bloom and bear fruit, and grow another season of rice. Since the ratoon rice grows again on the original root system, it can be harvested after about 2 months.

[0003] After the first-season rice matures, in order to retain 1 / 3 of the rice piles and root systems, the first-season rice can only be harvested by the traditional rice harvesting method. The traditional rice harvesting method relies on manpower, and the efficiency of manual rice harvesting is relatively low. It usually takes a long time to harvest the regenerated rice, which can be as short as a few days or as long as a month. Affected by the weather, rice can only be harvested on sunny or dry days, which further reduces the efficiency of rice harvesting. After the rice grows again on the retained 1 / 3 rice piles, since there is no need to continue to retain the rice piles, when harvesting the regenerated rice, a harvester can be used to harvest the regenerated rice. The application of the harvester effectively improves the harvesting efficiency of the regenerated rice and ensures that the regenerated rice in the rice field is harvested in a short time. However, the structure of some existing harvesters is relatively complex and inconvenient to produce; after the harvester harvests the regenerated rice, the rice stalks are discharged into the rice field on the spot. The rice stalks discharged into the rice field usually have rice grains left, and there is a situation where the regenerated rice is not completely threshed, resulting in a waste of rice grains.

[0041] Example 1

[0042] like Figure 1-18 As shown, a regenerated rice harvester provided by the present invention includes a regenerated rice cutting mechanism suspended on an external walking device, a regenerated rice transmission mechanism obliquely arranged on the external walking device and connected from the regenerated rice cutting mechanism, a regenerated rice threshing mechanism arranged on the external walking device and connected from the regenerated rice transmission mechanism, and a rice straw recovery mechanism and a rice grain receiving mechanism respectively arranged on the external walking device and respectively connected from the regenerated rice threshing mechanism.

[0043] The invention has a simple structure, a scientific and reasonable design, is easy to use, and is convenient for production and manufacturing. The invention adopts a double threshing drum to thresh the regenerated rice, and the threshing blocks on the threshing drum beat and roll the regenerated rice, so that the rice grains are threshed from the rice stalks, the threshing intensity of the regenerated rice is improved, and the residual grains on the rice stalks are reduced. At the same time, the invention recycles the rice stalks after threshing, so that the rice stalks can be manually fed into the threshing box for threshing again, so that the residual grains on the rice stalks are separated from the rice stalks, so that the regenerated rice is completely threshed and the waste of rice is avoided.

[0044] When the present invention is in use, an external walking device drives the present invention to move forward. During the movement, the two rice-selecting plates 20 on the cutting table 19 separate the regenerated rice to be harvested from other regenerated rice, and gather the regenerated rice to be harvested between the two rice-selecting plates 20. The rice-plowing wheel 22 rotates and pushes the regenerated rice to be harvested between the two rice-selecting plates 20 to the cutting knife 21. The cutting knife 21 cuts the regenerated rice off the ground. The agitator 23 guides the cut regenerated rice into the cutting table 19. The telescopic claw 24 pulls the regenerated rice in the cutting table 19 onto the conveyor belt 2. The conveyor belt 2 transports the regenerated rice to the position where the threshing box 3 is connected to the transmission shell 1. The threshing drum 4 in the threshing box 3 rotates and winds the regenerated rice onto the threshing screen plate 5. The threshing block 35 on the threshing drum 4 beats and rolls the regenerated rice on the threshing screen plate 5 to separate the rice grains from the rice stalks. 4 continues to rotate, and the threshing block 35 on the threshing drum 4 synchronously pushes the threshed rice straw backwards, so that the rice straw is transmitted to the end of the threshing screen plate 5 close to the rice straw outlet 8, and the rice straw falls into the recovery box 14 through the rice straw outlet 8 on the end of the threshing screen plate 5 close to the rice straw outlet 8. During the process of the threshing block 35 beating and rolling the regenerated rice on the threshing screen plate 5, the threshing screen plate 5 vibrates, and the rice on the threshing screen plate 5 falls onto the first material transporting plate 6 through the first sieve hole 59 on the threshing screen plate 5, rolls downward on the first material transporting plate 6, and falls onto the second material transporting plate 10 through the rice grain outlet 7, and continues to roll downward on the second material transporting plate 10 until it falls on the lifting belt conveyor 11, and is transported to the top of the silo 12 under the lifting action of the lifting belt conveyor 11, and enters the inside of the silo 12 through the feeding port 13 at the top of the silo 12. The rice stalks recovered in the recovery box 14 are fed into the threshing box 3 manually through the feeding port 18, and the threshing drum 4 in the threshing box 3 threshes the rice stalks again, so that the rice grains remaining on the rice stalks are separated from the rice stalks, and the regenerated rice is completely separated, so that the waste of rice grains can be avoided.

[0045] As the rice falls from the first transport plate 6 to the second transport plate 10, the hair dryer blows air to the falling rice, so that rice leaf fragments and other debris mixed in the rice are separated from the rice under the action of wind, and the rice leaf fragments and other debris are discharged to the outside, while the rice falls from the first transport plate 6 to the second transport plate 10.

[0046] The external walking device can be an external tracked vehicle.
