Improved rice transplanter

Abstract

The invention discloses an improved rice transplanter. The improved rice transplanter includes a frame and an engine disposed on the frame. The lower end of the frame is provided with traveling wheelsdriven by the engine, and the frame is provided with a seedling box, a branching device and a rice transplanter. The branching device is arranged at the outlet of the seedling box, and the branchingdevice is provided with a branching lever, the branching lever is connected to a speed governor, the speed governor is connected with the engine, and a throat is arranged at the outlet of the branching device. The structure of the transplanter includes a fixed clamp and a movable clamp, and the movable clamp is connected to the speed governor through a cam. The improved rice transplanter providedby the invention can solve the deficiencies of the prior art, and has the advantages of simple structure, high insertion efficiency and neat line spacing.

Description

technical field

[0001] The invention relates to an agricultural machine, in particular to an improved rice transplanter. Background technique

[0002] The development of Chinese rice transplanter began in 1953. In 1956, inspired by the method of planting and supporting seedlings, he proposed for the first time the principle of group seedling picking and direct planting, which made a breakthrough in the development of rice transplanters, and developed a rice transplanting machine. First generation prototype. By 1960, there were 21 types of human and animal power rice transplanters recommended for use in various places. In 1967, the first self-propelled motorized rice transplanter "Dongfeng-2S" passed the appraisal and was put into production. It can transplant 15-20 mu of rice every day.

[0003] my country's rice transplanter has been researched for nearly 50 years, and rice planting machinery still stays in the single-wheel pallet type for decades. So far, the average le...
