Problems solved by technology

Therefore, it is necessary to use narrow tracks or narrow wheels to reduce the rolling loss rate. At the same time, it is necessary to use a high-clearance chassis to adapt to the high stubble height. The rolling loss rate of traditional harvesters is as high as 50%, and the use of narrow tracks for low loss of ratooned rice The crushing rate of the harvester can be reduced to 26%, but the loss is still serious, which seriously affects the output of the second season rice

Embodiment

[0026] Such as Figure 1-Figure 4 The low-loss harvester for ratooned rice shown includes a header 1, a conveying system 2, a threshing and sorting system 3, a grain tank 4, and a grain unloading pipeline 5, as well as a driving mechanism, a walking mechanism with narrow shoe widths and a waste guide plate 6. The walking mechanism with narrow track width spacing includes a chassis 7, a high clearance chassis support 8, a left narrow track 9 and a right narrow track 10; the left narrow track 9 and right narrow track 10 pass through the high clearance chassis support 8 is connected to the chassis 7, the grain tank 4 and the threshing and sorting system 3 are installed on the chassis 7, the front of the grain tank 4 is provided with a cab 16, and the header 1 is connected to the threshing and sorting system through the conveying system 2 3, the grain unloading pipeline 5 is connected to the grain tank 4, the outer side of the narrow crawler belt 10 on the right side is flush with...

Abstract

The invention relates to the technical field of agricultural harvesting devices, and discloses a low-loss ratooning rice harvester. The low-loss ratooning rice harvester is characterized in that on the basis of an existing harvester, a right-side narrow crawler belt is biased to be flush with the outer side of a header, and a residue guide plate is mounted at a residue discharge port of a threshing and sorting system, so that residues can completely fall into indentations of a left-side narrow crawler belt. During harvesting, due to the fact that the right-side narrow crawler belt is offset and flush with the outer side of the header, the left-side narrow crawler belt of the next row can continue to walk in the indentation of the previous row, and the cutting width is not affected. The low-loss ratooning rice harvester is matched with a low-loss harvesting method, only three indentations are formed in two times of harvesting, and the rolling loss rate is only 13%.

Description

technical field [0001] The invention relates to the technical field of agricultural harvesting devices, in particular to a low-loss harvester and method for ratooned rice. Background technique [0002] The ratooning rice harvesting operation is different from the traditional single-crop rice harvesting. When the ratooning rice is harvested, only the upper 2 / 3 of the rice plant is cut off, and the rice ears are harvested, leaving 1 / 3 of the plant and root system, fertilized and cultivated, and let it grow for another season. rice seeds. Therefore, it is necessary to use narrow tracks or narrow wheels to reduce the rolling loss rate. At the same time, it is necessary to use a high-clearance chassis to adapt to the high stubble height. The rolling loss rate of traditional harvesters is as high as 50%, and the use of narrow tracks for low loss of ratooned rice The rolling rate of the harvester can be reduced to 26%, but the loss is still serious, which seriously affects the out...
