Plant row drill

Abstract

The invention relates to a plant-to-row seed drill. The plant-to-row seed drill comprises a rack and a land-wheel transmission device, wherein the left part and the right part of the rack are respectively provided with a marker; the rack is provided with seeding single bodies, ditching and earthing devices are arranged below the rack, and an operating platform is arranged at the rear part of the rack; one side of the operating platform is provided with a seed disc; the front end of the rack is provided with a row spacing adjusting device; the row spacing adjusting device comprises a box body, a power input device and a power output device; the power input device is connected with the land-wheel transmission device; the power output device is connected with the seeding single bodies; each seeding single body comprises a seed storage device, a seed releasing device and a seeding device arranged at the lower part of the seed storage device; and multi-group seeding single bodies and multi-group ditching and earthing devices are arranged on a seed drill body in parallel. The plant-to-row seed drill provided by the invention is a plant-to-row seed drill machine, and has the advantages that seed storage, seed releasing, seed sowing, ditching and earthing are integrated, simultaneous sowing of multi-type seeds can be realized, the comparing accuracy of the plant-to-row test is high, the seed damage rate is low, the mechanical degree is higher, and the seeding uniformity is better.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a row drill for sowing in border fields. Background technique [0002] Seed engineering has always been the focus of economic work in various countries. Improving the breeding of fine varieties, ensuring food security, and increasing food production have always been issues of great concern to our country. In 2010, the "No. 1 Document" of the central government pointed out that "the focus of agricultural science and technology should be placed on the cultivation of improved varieties, and the construction of the innovation and popularization and application system of agricultural biological breeding should be accelerated." In the stage of cultivating new varieties, a plant row drill with reliable performance, accurate testing and strong adaptability has become an urgently needed tool for breeding units. Foreign row sowing machinery and equipment are...

AI Technical Summary

Problems solved by technology

Foreign row sowing machinery and equipment are relatively expensive, and cannot well meet the breeding requirements of our country, especially cannot adapt to the agronomic requirements and breeding modes of the breeding units in the north and south of my country. However, the independent research and development technology of domestic row row sowing equipment is basically Blank, domestic row-sowing crop breeding work is still dominated by manual sowing, labor-intensive, seriously restricting the accuracy of breeding experiments, restricting the development of China's breeding industry

When the plot drill is operating, it is necessary to deal with the changes or adjustments of the test factors such as the seed variety, sowing amount, and sowing line length required by the plot, and to achieve clean seeding after the sowing is completed. In order to improve the sowing efficiency, it is also necessary to store seeds, sow, and cover soil. The integrated test and the reduction of seed damage rate have put forward higher requirements, and the current plot drills still have shortcomings in these aspects
