Embodiment Construction

[0018] In order to enable those skilled in the art to better understand the present invention, the present invention will be further clearly and completely described below in conjunction with the accompanying drawings.

[0019] figure 1 The grain seeder shown includes a frame 1 and one or more individual sowing groups connected with one frame 1 .

[0020] The single sowing group includes: single steel frame 2, seed meter assembly 3, suppression mechanism 4, sheath type seeder 5 and slider profiling structure 6, and the seed meter assembly 3 is fixed on the single steel frame 2 The top and the bottom of the seed meter assembly 3 are connected with the seed pipe 7, the suppression mechanism 4 is fixed on the bottom of the single steel frame 2, the suppression mechanism 4 and the seed meter assembly 3 are connected by a chain transmission mechanism 8, and the sheath seeder 5 Be fixed on seed pipe 7 bottoms.

[0021] The seed metering device assembly adopts a wheeled millet seed...

Abstract

The invention relates to a grain seeder. The grain seeder comprises a rack and one or more individual seeding units connected with the rack, wherein the individual seeding units are connected with the rack by a sliding block copying structure, the sliding block copying structure comprises a guiding outer sleeve and a sliding block, a cavity structure is formed inside the guiding outer sleeve, the sliding block is arranged inside the cavity structure, the guiding outer sleeve of the sliding block copying structure is perpendicular to the ground and is fixed on the rack, the sliding block is connected with an individual steel frame to form one or more-row integrated seeder; and a compacting mechanism is provided with two compacting wheels, and the radial projections of the two compacting wheels are positioned at two sides of a sheathed seeder. According to the grain seeder, the height and the length of the whole grain seeder can be reduced, the seed charge height is lowered, the seed charge accuracy can be ensured, the seed exposure phenomenon can be avoided, one-row and multi-row combinations can be realized to meet the seeding demands of different fields, and almost no secondary disturbance is caused to the settled and cured soil, thereby providing a good condition for ground breakage and seedling emergence for seeds.

Description

technical field [0001] The invention relates to a seeder, in particular to a seeder suitable for sowing millet. Background technique [0002] Thinning-free sowing is the basis for mechanized production of millet. There are actual conditions in my country's millet planting areas such as different sizes of plots, high labor intensity for thinning seedlings, and drought and water shortage during the sowing period. To meet the needs of millet sowing in different plots, the measures that need to be taken: (1) reduce the height and length of the whole machine; The ditching suppression seeding system that has little soil secondary disturbance and can sow seeds to wet soil, this system should also be able to realize the function of instant profiling, avoiding the disadvantages of the existing seeder profiling ahead or behind. The existing millet seeder has the problems of large seeding rate, poor uniformity, low reliability, long profiling distance and easy seed exposure. Content...
