Walking type transplanting mechanism of rice transplanter

Abstract

A walking type transplanting mechanism of a rice transplanter comprises a power output shaft and spline housings, wherein the power output shaft is connected with sprocket shafts through the spline housings and placed in a casing, the other end of one sprocket shaft outside the casing is connected with a driving sprocket arranged in a sprocket box, a driven sprocket is arranged at the other end of the sprocket box, a seedling pawl axle is arranged at the lower part of the driven sprocket, connected with a crankshaft of a transplanting arm through a spline and connected with a seedling pawl fixing block, a support arm is arranged at the bottom of the casing, and a fixing rod is arranged in the middle. The walking type transplanting mechanism has the advantages as follows: the structure is simple, the working efficiency is high, the transplanting density is increased, the unit area effectiveness is increased, and the higher yield is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a planting mechanism of a walking rice transplanter. Background technique [0002] Rice is one of the most important food crops in my country, and machine transplanting is an important part of rice production. The transplanting mechanism is the core part of the rice transplanter, which plays the role of separating a certain number of seedlings from the seedling group and inserting them into the soil. Its performance directly affects the quality and efficiency of rice transplanting. At present, there are mostly 30cm row-spacing rice transplanters on the market, which are widely used in northern my country; but for the double-cropping rice area of ​​southern early rice and continuous cropping late rice, early and late rice have the characteristics of short growth period and relatively short plants, so use 30cm row spacing for transplanting The density of seedlings pl...

AI Technical Summary

Problems solved by technology

At present, there are mostly 30cm row-spacing rice transplanters on the market, which are widely used in northern my country; but for the double-cropping rice area of ​​southern early rice and continuous cropping late rice, early and late rice have the characteristics of short growth period and relatively short plants. The density of the seedlings planted by the machine is relatively thin, and it is often difficult to completely seal the seedlings when they mature, resulting in insufficient effective panicles, which is not conducive to high-yield rice.
