Rice carding harvester

Abstract

The invention discloses a rice carding harvester, which mainly comprises a power machine, a gearbox, a belt drive device, a threshing roller, a grain conveying belt, a seedling rotating disc, travelling wheels, a machine frame and the like. Without adopting the conventional crushing threshing and roller seedling snapping method, the crushing efficiency loss and spreading loss are avoided radically and loss in harvest is very small; the rotation of straw is avoided and the cleaning step after threshing is avoided, so energy consumption is lowered obviously; and the harvester is light and convenient for disassembly and assembly, can adjust the height of a threshing system according to the height of rice plants and is particularly suitable for operation in paddy fields in mountain and hill areas.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a first-off rice harvester. Background technique [0002] At present, in terms of rice harvesting, the use of full-feed and half-feed harvesting machinery is increasingly promoted, but there are still the following shortcomings: [0003] 1. During the harvesting operation, the grain loss is large, including the breakage rate and scattering rate, which is about 5% or more. The total loss of more than 400 million mu of rice in the country (manual work also has losses) is more than 20 billion catties. [0004] 2. Since the rice is cut first and then removed, the rice and straw need to be operated in the machine, and the heavy crushing bin is threshing, and multiple steps such as cleaning are required, which consumes a lot of energy. [0005] 3. Due to the weight of the machine, paddy field operations are difficult (late rice transplanting in double-cropping rice area...

AI Technical Summary

Problems solved by technology

[0003] 1. During the harvesting operation, the loss of grain is large, including the broken rate and scattering rate, which is about 5% or more. The total loss of more than 400 million mu of rice in the country (manual work also has losses) is more than 20 billion catties

[0004] 2. Since the rice is cut first and then removed, the rice and straw need to be operated in the machine, and the heavy crushing bin is threshing, and multiple steps such as cleaning are required, which consumes a lot of energy.

[0005] 3. Due to the weight of the machine, paddy field operations are difficult (late rice transplanting in double-cropping rice areas must be paddy fields, and dehydration harvesting is not conducive to the promotion of double-cropping rice)

At the same time, it is difficult to carry when working in hills and mountains

[0006] 4. The price is expensive, especially the imported semi-feeding harvester, which is as high as hundreds of thousands of yuan per unit
