Wide- and narrow-row handheld rice transplanter with wide partition in seedling box

Abstract

The invention discloses a wide- and narrow-row handheld rice transplanter with a wide partition in a seedling box, which comprises an engine, a ground profiling mechanism, two driving wheel systems, a seedling claw movement mechanism, a seedling box movement mechanism and a handheld operating system. The seedling box with the wide partition of the invention can ensure that only a set of spiral shaft for feeding seedlings transversely is required when the ratio of wide rows to narrow rows of the rice transplanter is not an integral multiple, so the seedling feeding mechanism is greatly simplified. The principle and the structure of the spiral shaft mechanism for feeding seedlings transversely of the wide- and narrow-row hand-held rice transplanter are the same as those of the spiral shaft mechanism for feeding the seedlings transversely of an equal-row rice transplanter, so the design and manufacturing cost of the wide- and narrow-row hand-held rice transplanter is greatly reduced.

Description

technical field [0001] The invention relates to a rice planting machine, in particular to a hand-held rice transplanter with wide partitions and wide and narrow row spacing. Background technique [0002] Present walk-behind rice transplanter all is the rice transplanter of equal row spacing, and promptly the row spacing of inserted rice seedling is all 30cm. But, in some areas and rice varieties need wide and narrow rows of rice transplanting row spacing, to be beneficial to the light transmission and ventilation of rice growth, just need the rice transplanting of wide and narrow rows as the rice transplanting of double-cropping rice. [0003] When the walk-behind rice transplanter is working, the operator holds the two handrails of the rice transplanter and walks between the rice seedlings in the middle two rows, and the two driving wheels walk between the other two rows. [0004] The transplanting action of the rice transplanter is divided into three parts: taking seedlin...

AI Technical Summary

Problems solved by technology

The wide row spacing formed by stopping the work of one row of seedling claws often cannot meet the requirements of agronomy, and cannot be used on hand-held rice transplanters with only 4 rows.

[0008] According to the working principle and structure of the current hand-held rice transplanter and ride-on rice transplanter, to realize wide-row transplanting, as long as the row spacing of the wide row is not an integer multiple of the narrow row, such as 2 times or 3 times, the seedling box of the rice transplanter Transverse seedling delivery mechanism just must adopt two seedling box screw shafts, promptly the seedling box screw shaft mechanism of a wide row spacing and the seedling box screw shaft mechanism of a narrow row spacing; slideways, the structure of the entire wide and narrow rows of rice transplanting will be very complicated

Therefore, no one has designed a truly practical wide and narrow row rice transplanter in which the row spacing is not an integer multiple.
