Rice transplanting mechanism provided with eccentric gear train and used for rice transplanter

Abstract

The invention discloses a rice transplanting mechanism provided with an eccentric gear train and used for a rice transplanter. The rice transplanting mechanism comprises a case with certain accommodating space, a transmission shaft perpendicularly inserted into the case, rice seedling separating mechanisms arranged at two ends of the case and the eccentric gear train arranged in the case, wherein the eccentric gear train comprises an eccentric driving wheel located at the center of the case, two eccentric driven wheels arranged on two sides of the eccentric driving wheel and eccentric drive gears arranged on the outer sides of the eccentric driven wheels; the eccentric driving wheel, the eccentric driven wheels and the eccentric drive gears are radially arranged in the case in a line and mutually meshed, and the transmission shaft penetrates through the case to be connected with the eccentric driving wheel. The rice transplanting mechanism has the benefits that the structure of the mechanism can be simplified at the utmost when the finished product rate and the efficiency of rice seedling transplanting are ensured, and the structure reliability of the rice transplanting mechanism is sufficiently guaranteed.

Description

technical field [0001] The present invention relates to a rice transplanting mechanism, more specifically, to an eccentric gear train rice transplanting mechanism of a rice transplanter. Background technique [0002] The transplanting mechanism is the main working part of the rice transplanter, which is composed of a seedling taker, its driving mechanism and a trajectory control mechanism. Under the driving of the driving mechanism and the control of the trajectory control mechanism, the seedling taker takes a certain amount of seedlings from the seedling box according to a certain trajectory and inserts them into the soil, and then returns to the original position to start the next cycle. According to the action of seedling separation, there are two types: horizontal and vertical: [0003] The horizontal seedling picker has a seedling clamp suitable for pulling out seedlings for planting and a cutting-type seedling claw suitable for planting seedlings with soil, and the tw...

AI Technical Summary

Problems solved by technology

[0007] Since the seedling separating mechanism of the above-mentioned rice transplanting mechanism is fixedly connected with the casing, the force in the process of seedling separating and transplanting remains unchanged, which easily causes the problem of too large or too small force for separating and transplanting rice seedlings, and the yield of rice seedling transplanting is low. In the later stage, a large number of artificial seedlings are needed, and the efficiency of transplanting is low
