Description

Manual light transplanter

Technical Field

The utility model relates to a rice transplanter, in particular to a manual light rice transplanter, and belongs to the field of agricultural implements.

Background

Due to the irregular terrain of farmlands and the geographical environment of cultivated lands, when a common rice transplanter is used for planting in complicated farmlands, the rice transplanter cannot easily plant seeds, a common planting mode of manpower and machines is adopted, the labor input is increased, if the rice transplanter is in hilly lands, the driving wheels of the rice transplanter cannot easily climb over ridges of the fields, the rice transplanter needs to completely plant seeds by manpower, and the difficulty is greatly increased for planting.

Under the current situation of rural areas in China, most young and old people go out for business, most of the people left behind are old, young, women and children, the manual transplanting is time-consuming and labor-consuming, the efficiency is low, the large-scale transplanting machine is inconvenient to operate, and the transplanting machine is very expensive.

In order to meet the current domestic requirements for cultivated land, liberate labor force and change the traditional mode of bending over for transplanting rice, the conventional rice transplanter on the market is high in price, not strong in rice seedling separating capability, not high in uniformity, easy to damage rice seedlings and incapable of being popularized to common families, so that the problem that the rice transplanter which is simple and easy to operate and low in price is designed is urgently needed to be solved.
