Dual-header dual-roller high-clearance rice harvesting machine

Abstract

The invention discloses a dual-header dual-roller high-clearance rice harvesting machine which comprises a walking power system provided with a hydraulic continuously variable transmission and an engine, a high-clearance base disc provided with a walking device, a dual-roller cleaning assembly arranged on the high-clearance base disc, a dual ear collecting header located at the front end of the dual-roller cleaning assembly, two scraper-type straw conveying devices located at left and right straw outlets and installed on a high-clearance base disc rack, a driving cab and a control console located at the upper end of the engine, a pair of grain elevators arranged on the two sides of the driving cab and the control console, and a dual-layer lower cutting tool arranged below a shell of the dual ear collecting header. According to the dual-header dual-roller high-clearance rice harvesting machine, the operation height of the dual-layer lower cutting tool can be adjusted, the harvesting machine is applicable to the crop harvesting operation with the requirement for the stubble height, only ear heads are cut down, the working efficiency can be effectively improved, the threshing and cleaning power consumption are lowered, discharged crushed straw is laid on a caterpillar band to be ground, the phenomenon that straw covers stubble is avoided, and the harvesting machine is applicable to common rice harvesting operation.

Description

technical field [0001] The invention relates to the technical field of harvesting equipment, in particular to a double-cutter double-drum high-gap rice harvester, which is suitable for harvesting ratooned rice and ordinary rice. Background technique [0002] Raising rice is a kind of rice variety, mainly distributed in the southern part of my country where the single-cropping rice has more calories but the double-cropping rice has insufficient calories, and the double-cropping rice only grows one-cropping rice, such as Sichuan and Fujian. The characteristic is that after the first season of rice matures, only about 2 / 3 of the rice plant is cut off, and the rice ears are harvested, leaving 1 / 3 of the rice plant and root system, and the regeneration ability and reasonable cultivation techniques are used to make it continue to germinate Seedlings, secondary maturity. Compared with ordinary rice, ratooning rice has the advantages of short growth period, high daily yield, less p...

Problems solved by technology

[0004] At present, the existing rice harvesters generally use 400mm~600mm wide crawlers or walking wheels, which require the height of the piles. The rolling rate of the crops is high and the ground clearance of the chassis is low, which will cause great damage to the piles.

Because ratooning rice has the characteristics of poor dehumidification and green branches and green leaves when harvesting, the traditional harvesting method is easy to cause drum blockage, which is not suitable for harvesting ratooning rice.
