High speed pot seedling Z-shaped wide-narrow row transplanting mechanism

Abstract

The invention discloses a high-speed pot seedling Z-shaped wide-narrow row transplanting mechanism. The rice Z-shaped wide-narrow row planting is a high luminous efficient rice agricultural mode, and mainly relies on artificial realization. Two transplanting arms at one side are installed at the left and the right sides of a gear box, and can simultaneously transplant two rows of seedlings. The mechanism combines a variable transmission characteristic of a non circular gear with a space transmission characteristic of a staggered helical gear through the form of a variable differential velocity combination gear system. The wide-narrow row transplanting of the rice pot seedling is realized by a large buckle space ''8-shaped'' track. The two transplanting arms work alternately, and the Z-shaped transplanting is realized. The variable differential velocity combination gear system realizes free transmission ratio through the combination form of a chain wheel and the gear transmission, and the mechanism can realize complex transplanting tracks.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a high-speed Z-shaped wide and narrow row transplanter for rice pot seedlings, in particular to a high-speed Z-shaped wide and narrow row transplanter for rice pot seedlings. Background technique [0002] At present, there are various types of rice transplanters, but whether it is transplanting in wide and narrow rows or transplanting in equal rows, the seedlings taken by the transplanting mechanism are all blanket-shaped seedlings, which are easy to damage the roots. The seedlings taken by the pot seedling wide and narrow row transplanting mechanism are pot seedlings, and there is no root packing phenomenon between the pots and pots, so there is no problem of root damage during the seedling picking process. Compared with blanket seedlings, transplanting has a shorter This is of great significance for increasing rice yield. [0003] Rice Z-shaped wide and narrow row planting ...

Problems solved by technology

[0004] The patent application with publication number CN102640604A discloses a high-speed rice transplanter non-circular gear wide and narrow row transplanting mechanism. To a certain extent, the law of motion satisfies the seedling-taking, transplanting trajectory and posture of the transplanting mechanism's needle, but its function is limited to the "kidney-shaped" trajectory or "dolphin-shaped" trajectory of the rice transplanter, and cannot satisfy the Z-shaped shape of rice pot seedlings. Requirements for transplanting in wide and narrow rows

[0005] The invention patent with the publication number CN103493634A proposes two schemes for a space planetary gear system corn wide and narrow row oblique Z-shaped transplanting mechanism. The transplanting track is arranged at 90° through two gear boxes to realize staggered seedling picking and transplanting. This mechanism can improve the ventilation and light transmittance between plants; however, the transplanting track realized by the bevel gear mechanism has a relatively small Large offset, low seedling success rate
