Handhold wide-narrow row rice transplanting machine with seedling box partition plates of unequal spaces

Abstract

The invention discloses a handhold wide-narrow row rice transplanting machine with seedling box partition plates of unequal spaces. The rice transplanting machine comprises an engine, a ground copying mechanism, two driving wheel systems, a seedling claw moving mechanism, a seedling box moving mechanism and a handhold operating system. The seedling box with partition plates of unequal spaces of the invention only needs one set of screw shaft mechanism for feeding the seedling transversely when the ratio of the spaces of the wide and narrow rows of the rice transplanting machine is not integral multiple, thereby greatly simplifying the seedling feeding mechanism. The screw shaft mechanism for feeding the seedling transversely of the invention is the same as that of the rice transplanting machine of equal space in terms of principle and structure so as to greatly reduce the design and manufacturing costs of the wide-narrow row rice transplanting machine; and because the size and shape of the middle partition plate of the seedling box are the same as those of other partition plates, the cost for manufacturing the partition plate mould is reduced.

Description

technical field [0001] The invention relates to a rice planting machine, in particular to a wide and narrow row hand-held rice transplanter with unequal distances between seedling box partitions. Background technique [0002] Existing 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 thre...

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 the transplanting of wide and narrow rows, as long as the row spacing of the wide row is not an integral multiple of the narrow row, such as 2 times or 3 times, the seedling box of the rice transplanter The horizontal seedling feeding mechanism must adopt two seedling box double helix shafts, that is, a wide row spacing seedling box double helix shaft mechanism and a narrow row spacing seedling box double helix shaft mechanism; box, two slides, the structure of the entire wide and narrow rows of rice transplanting will be very complicated

[0009] Therefore, no one has designed a truly practical wide and narrow row rice transplanter in which the row spacing is not an integer multiple.
