Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a three-dimensional three-linkage periodic stepping mechanism with one-way drive. On the other hand, it can also solve the problem of roof leakage in the descending movement of the grid seedling tray. At the same time, only one driving mechanism is needed to realize the control of each ejector needle assembly and its related assemblies during work. drive, so it also has the advantage of high drive efficiency

Abstract

The invention discloses a unidirectionally-driven three-dimensional three-linkage-period stepping mechanism. The stepping mechanism comprises seedling ejecting needle assemblies, a telescopic drivingmechanism, a moving driving mechanism, a stepping descending driving mechanism and a total power mechanism, wherein each seedling ejecting needle assembly comprises a plurality of seedling ejecting needles and a fixed component; the telescopic driving mechanism comprises a first reciprocating driving frame, a first incomplete gear and a first gear shaft; the moving driving mechanism comprises a first pushing component, a second reciprocating driving frame, a second incomplete gear and a second gear shaft; and the stepping descending driving mechanism comprises a blocking rod assembly and a movable mechanism. According to the unidirectionally-driven three-dimensional three-linkage-period stepping mechanism, the problems that a seedling ejecting needle driving mechanism is large in driving force and inflexible during the driving can be solved, the problem of top exposure in the descending motion of a grid seedling disc can be solved, and each seedling ejecting needle assembly and relevant assemblies can be driven only through one driving mechanism, so that the stepping mechanism has the advantage of high driving efficiency.

Description

technical field [0001] The invention relates to a seedling seeding machine, in particular to a three-dimensional three-linkage periodic stepping mechanism of the seedling seeding machine driven in one direction. Background technique [0002] At present, the known rice planting machines are mainly divided into two categories: 1. Traditional rice transplanters based on manipulators (claws) to tear and cut blanket-shaped seedling roots to plant in pockets; Rice transplanter; Among them, the first type of rice planting machine technology is relatively mature, and the high-frequency drive of the engine can be used to plant to achieve high planting efficiency. Its disadvantage is that it will damage the roots. The operation of rooting and transplanting seedlings into the mud requires a lot of power and requires high strength of mechanical materials. The mechanism is usually cumbersome, the cost of consumables and energy consumption is high, and it is inconvenient to operate in hil...
