Small combine harvester for rice

Abstract

A small combine harvester for rice is mainly composed of a reel wheel, a side conveyor fan, a threshing device, a hanger, a hydraulic lifting mechanism, a hand support chassis, an engine, an ultra-wide low-pressure tires, a secondary cutting mechanism, a primary mechanism, a splitter and a transfer system; the hand support chassis uses the GN-71 hand tractor chassis; the engine is a diesel engineand is arranged at the back of the whole machine; the side conveyor fan is centrifugal; the impeller structure is backward straight board type; a front end of the blade is arc shaped; the cutter is asingle moving blade reciprocating cutter; a certain number of blade protectors with fixed blades are installed on the cutter beam; the secondary cutting mechanism has the hydraulic elevating header linkage design and is close to the bottom of the header. The invention has the advantages of simple structure, reasonable arrangement, convenient installation, high work efficiency, low production cost,stable operation, and simple operation, and can well meet the rice harvesting requirements in mountainous and hilly regions.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a small rice combine harvester. Background technique [0002] The rice planting area in my country is about 2.93×10 7 hectares, accounting for about 30% of the grain planting area; rice production accounts for 40% of the grain output. The northern part of my country mainly adopts segmental harvesting methods, but the promotion and application of rice combine harvesters is very fast, mainly because its geographical conditions are better than those in the south. Hunan, Jiangxi, Fujian, Anhui and other provinces with the largest rice production area and output in southern my country have large differences in natural conditions, crop varieties, farming habits, agronomic requirements, and economic conditions compared with those in the north. Due to the small fields in these places, heavy rain, deep rotten mud feet, few fields, large drop between fields, narrow machine ...

AI Technical Summary

Problems solved by technology

Hunan, Jiangxi, Fujian, Anhui and other provinces with the largest rice production area and output in southern my country have large differences in natural conditions, crop varieties, farming habits, agronomic requirements, and economic conditions compared with those in the north. Due to the small fields in these places, heavy rain, deep rotten mud feet, few fields, large drop between fields, narrow machine plowing roads, large and medium-sized combine harvesters are not suitable for these areas, etc., rice combine harvesters are used more. The mechanization level of rice production is relatively low, and the rice harvesting method is mainly manual harvesting. The entire harvesting process is completed manually, which is labor intensive.
