Rail-mounted regeneration rice harvesting device

Abstract

The invention provides a rail-mounted regeneration rice harvesting device, which has no rolling damage to root stubbles, can effectively improve the effective spike number and the yield. The device ischaracterized by comprising: a guide rail assembly, wherein the guide rail assembly comprises two groups of guide rails which are parallel to each other and are laid on a ridge at an equal distance;a gantry, wherein the gantry is arranged on the guide rail assembly and comprises two supporting leg parts which are respectively corresponding to the two groups of guide rails, a cross beam which isarranged on the two supporting leg parts, and two rollers which are respectively arranged at the bottom ends of the two supporting leg parts and can move back and forth along the axial direction of the guide rails; a sliding assembly, wherein the sliding assembly is arranged on the cross beam and can move back and forth between the two supporting leg parts along the crossbeam; a rotating and lifting assembly, wherein the rotating and lifting assembly is connected with the sliding assembly and comprises a rotating element capable of rotating, and a lifting element connected with the rotating element and capable of moving up and down; and a harvesting assembly, wherein the harvesting assembly is arranged at the bottom of the rotating and lifting assembly and is used for harvesting the regeneration rice.

Description

technical field [0001] The invention belongs to the field of harvesting devices, and relates to a track-type regeneration rice harvesting device. Background technique [0002] Raising rice is a kind of rice variety, which has a long history of planting in China. After the first season of ratooning rice is harvested, certain cultivation and management measures are taken to re-emerge seedlings, grow spikes, flower and set fruit, and the second season can be harvested, also known as "one kind of two harvests". In recent years, under the promotion of agricultural departments at all levels, ratooning rice has developed rapidly. Compared with double-cropping rice, which is also harvested for two seasons, ratooning rice not only saves arable land once, saves one season of seeds, but also requires less fertilization and basically no pesticides, and the straw does not need to be burned. More importantly, it saves labor. good quality. [0003] At present, the harvesting methods of ...

AI Technical Summary

Problems solved by technology

[0003] At present, the harvesting methods of ratooning rice include manual harvesting and mechanized harvesting. The main problem of the existing mechanized harvesting methods is that rolling significantly reduces the germination of ratooning tillers, which seriously affects the yield of ratooning rice.

Manual harvesting of the first season rice can increase the yield of ratooning rice, but the cost is high

The mechanized harvesting of the first crop rice can save time and labor and improve production efficiency, but the number of buds in the unrolled part of mechanical harvesting is 71.8% of that of manual harvesting, and the number of buds in the rolled part is only 25.4% of manual harvesting; mechanical harvesting is more effective than manual harvesting. The number is reduced by 22.6%-50.9%, and the output is reduced by 23.4%-41.9%.
