Rice transplanter control guiding shaft

Abstract

The invention discloses a rice transplanter control guiding shaft. The shaft comprises a shaft body, the annular outer wall of the shaft body is provided with a guiding slot with a semicircular section, a semicircular movable compression sheet and a semicircular cam pad are in sliding fit in the guiding slot, the semicircular outer wall of the movable compression sheet and the semicircular outer wall of the shaft body form the spiral slot annular wall of the shaft body, the spiral slot annular wall of the shaft body is provided with two groups of continuous spiral slots with opposite spiral directions, same spiral distance and same width, and a difference between the phase angles of the two groups of the spiral slots is 180DEG; the bottom of the guiding slot, the cam pad and the movable compression sheet are respectively provided with a plurality of groups of mutually cooperating locating holes, locating columns are inserted into the locating holes of the movable compression sheet and the guiding slot and the locating holes of the cam pad and the guiding slot; and the cam pad is positioned at the right side of the movable compression sheet. The shaft improves the adaptation range of the same rice transplanter, realizes adjustable line spacing, and cooperates with a rice seedling box under a corresponding line spacing in order to realize a lateral movement amount.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a rice transplanter control guide shaft. Background technique [0002] At present, in the field of rice transplanters, there are mainly several types of mechanisms for laterally moving boxes, such as rack type, turntable rack type, chain type, and spiral groove type. The box-moving control method with a fixed amount of box-moving can no longer fully meet the needs of agronomy and planting in different regions. In our country, the area is vast, the climate environment and topography of each region are different, and the soil fertility status of each region is also quite different. According to the different conditions and requirements of each region, the planting density and growth cycle are also different. Therefore, it is necessary to When transplanting seedlings, the row spacing of transplanting is adjusted to meet the requirements of agronomy in various places. Con...
