Problems solved by technology

However, Japan is a single-cropping rice country, and its subplanting mechanism is mainly suitable for small seedling operations of rice seedlings (early rice transplanting). In southern my country where double-cropping rice is planted, only one season can be planted, so its application range is greatly reduced.

Abstract

The present invention discloses separating and planting mechanism of eccentric knuckle gear-nonknuckle gear planetary train. There are one central chain wheel inside the chain wheel box to rotate the right and the left gear boxes, two fixed central eccentric knuckle gears in the gear boxes, two nonknuckle gears meshed separately with the central eccentric knuckle gears and rotating with the nonknuckle gears and one planetary eccentric knuckle gear meshed with these two nonknuckle gears, with the five gears having rotating centers in the same straight line. The planetary eccentric knuckle gear rotates with the gear boxes in even speed while rotating in uneven speed relatively to the gear boxes. One pair of planting arms fixed to the planetary eccentric knuckle gear via the planetary gear shaft performs uneven speed oscillation, and proper structural parameters ensure the operating track of the rice seedling pin suitable for forward planting operation.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an eccentric circular gear-non-circular gear planetary system insertion mechanism. Background technique [0002] At present, the rice motor-driven rice transplanter sold on the domestic market has two forms of its planting mechanism: a kind of is crank rocker type inserting mechanism, and another kind is rotary type inserting mechanism. The former can work normally when the working frequency is 200-220 times / min. With the increase of the frequency of the transplanter, the vibration of the frame of the transplanter will be aggravated; at the same time, the linear speed of the seedling needle in the planting mechanism is too high, which will cause uneven seedling separation. The rate of injured seedlings and the rate of missing seedlings increase, and the planting arm is vulnerable, which limits the improvement of work efficiency. The latter is an eccentric gear and an elliptical gear pla...
