Pen type precise seeder

Abstract

The invention provides a pen type precise seeder which comprises an air sucking and blowing device (1), a first seed bin (3), a coarse screen piece (32) arranged in the first seed bin (3), a second seed bin (4), a bearing base (9) arranged in the second seed bin (4), and a seeding rod (6). The side wall, located in the seed bin (4), of the seeding rod (6) is provided with a seed inlet (10). A locking plate (8) for controlling the seed inlet (10) to be opened and closed is arranged in the seeding rod (6). A check valve (11) is arranged at the position, located below the seed inlet (10), of theseeding rod (6). A ventilation quantitative rod (2) is movably arranged in the seeding rod (6). A cavity (14) is formed between the ventilation quantitative rod (2) and the check valve (11). The pen type precise seeder has the advantages that the seeding amount of seeds can be controlled, the structure is simple, and scientific research work can be conveniently conducted due to the pen type structure.

Description

technical field [0001] The invention relates to the technical field of seeder equipment, in particular to a precision seeder. Background technique [0002] The seeder is an instrument for sowing. In the process of agriculture and scientific research, many small seeds need to be sown, but it is difficult to precisely control the amount of seeds sown during the sowing process. And most of the current seeders have complex structures, which are not only conducive to the use of scientific research, but also have high production costs. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the defects of the prior art, and to provide a pen-type precision seeder capable of controlling the seeding amount. [0004] The technical solution adopted by the present invention to solve the above problems is that a pen-type precision seeder includes an air suction and blowing device, a first seed bin, a coarse screen arranged in the first seed bin, and a sec...
