Straight-type rice pot seedling wide and narrow row transplanting mechanism

Abstract

The invention discloses a direct taking type rice pot seedling wide-narrow row transplanting mechanism. A seedling taking track of an existing rice pot seedling wide-narrow row transplanting mechanism has the large transverse shifting amount at the seedling taking segment, and the seedling taking success rate is low; according to the first scheme, the two sides of a center non-conical gear are engaged with an upper middle non-conical gear and a lower middle non-conical gear correspondingly, an upper middle bevel gear and an upper middle non-conical gear are coaxially mounted and are engaged with an upper planetary bevel gear, and a lower middle bevel gear and a lower middle non-conical gear are coaxially mounted and are engaged with a lower planetary bevel gear; according to the second scheme, the two sides of a center plane non-round gear are engaged with an upper middle plane non-round gear and a lower middle plane non-round gear, an upper middle conical gear and an upper middle plane non-round gear are coaxially mounted and are engaged with an upper planetary conical gear, and a lower middle conical gear and a lower middle plane non-round gear are coaxially mounted and are engaged with a lower planetary conical gear. The transverse shifting amount of the seedling taking segment track is smaller than 2mm, and direct seedling taking is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a high-speed pot seedling wide and narrow row transplanting machine, in particular to a direct-taking type rice pot seedling wide and narrow row transplanting mechanism. Background technique [0002] At present, rice transplanters have been widely used, but the rice shoots taken by the transplanting mechanism of the rice transplanter are all blanket-like seedlings. By tearing the rice seedlings and inserting them into the field, the roots of the rice seedlings are easily damaged. The seedlings taken by the pot seedling wide and narrow row transplanting mechanism are pot seedlings, and the seedlings between the pot and the pot are independent of each other, and there is no root packing phenomenon, so there is no problem of root damage during the seedling picking process. There is no slow seedling period, so the rice growth cycle can be shortened, which is of great significance ...

Problems solved by technology

The patent application with the publication number CN102640604A discloses a non-conical gear wide and narrow row transplanting mechanism for a high-speed rice transplanter. The law of motion satisfies the seedling picking, transplanting trajectory and posture of the transplanting mechanism needle to a certain extent, but its function is limited to the "kidney-shaped" trajectory or "dolphin-shaped" trajectory of the rice transplanter, and cannot form a pot seedling transplanting place. The required "8-shaped" space complex trajectory, that is, the mechanism proposed in this patent can only be applied to rice transplanters, and cannot meet the requirements of transplanting rice pot seedlings in wide and narrow rows

[0005] Publication number is that the patent of CN103004346A discloses a kind of non-conical gear pot seedling wide and narrow row transplanting mechanism. In the process of picking seedlings, the clip clamps the potting soil of the pot seedlings; the transplanting track of this mechanism is a space movement track with a sharp beak, and there will be a large impact vibration during high-speed operation, and the reliability is not high

[0006] The patent application with the application number CN201310318352.7 discloses a seven non-conical bevel gear planetary gear system seedling wide and narrow rows transplanting mechanism, the core component of the mechanism is a seven non-conical bevel gear planetary gear system, and its seedling claws can be Realize the "figure 8" spatial movement track, but the "figure 8" transplanting track of this mechanism has a large lateral offset in the seedling picking section, that is, the movement of the seedling claws while picking seedlings is laterally offset. It interferes with the left and right seedling feeding actions of the seedling box, resulting in inaccurate seedling picking and a low success rate of seedling picking
