Small field sower

Abstract

The invention relates to a small field sower, which comprises a frame, and a seed supply device, a seed dropping device, a seed dropping control device and a ditching and covering device which are positioned on the frame. The rear of the frame is provided with a seed supply operating platform; one side of the seed supply operating platform is provided with the seed supply device, while the other side is provided with a seed dropping control operating platform; the front of the seed supply operating platform is provided with the seed dropping device; the ditching and covering device is arranged under the frame; and the seed dropping device is connected with the ditching and covering device through a grain tube. The small field sower eliminates instability of power supply of a ground wheel in mechanical seed dropping, reduces power loss caused by a plurality of mechanical transmission links, improves mechanical transmission efficiency, adopts motor control to replace the conventional mechanical control mode, has a simple structure, improves the sowing accuracy due to constant power output, greatly reduces adverse effect caused by a seed dropping control transmission system, improvesthe accuracy, scientificity and universality of small field contrast test study, and meets the current development requirement of small field sowers in China.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a plot seeder integrating functions such as seed supply, seed storage, seed filling, seed sorting, ditching, and soil covering. Background technique [0002] According to the situation and characteristics of China's agriculture, the Ministry of Agriculture clearly stated at the "National Agricultural Seed Work Conference" in September 1995 that "create a seed project to promote agriculture to a new level". In October 1995, the "Suggestions of the Central Committee of the Communist Party of China on Formulating the Ninth Five-Year Plan for National Economic and Social Development and the Long-term Goals for 2010" passed by the Fifth Plenary Session of the Fourteenth Central Committee of the Party clearly stated: focus on seed projects and implement seed projects. Project to improve the breeding, introduction, processing, sales and promotion system of...

Problems solved by technology

[0003] The purpose of the present invention is to improve the mechanical transmission seeding method commonly used in the existing plot seeders, and provide an electronically controlled transmission mode instead of the traditional one, so as to solve the complex structure of the transmission part of the conventional plot seeders and the unstable power transmission It is a plot seeder that guarantees the accuracy, scientificity and universality of field comparative experiments and research due to shortcomings such as uneven seeding.
