Plot seed sowing device

Abstract

The invention belongs to the field of seed sowing devices, and particularly provides a plot seed sowing device which comprises a seed groove and seed discharge barrels. First seed discharge holes and second discharge holes are formed in the bottoms of two sides of the seed groove, and first seed discharge barrels and second seed discharge barrels which are matched with the first seed discharge holes and the second seed discharge holes are arranged at the bottoms of the two sides of the seed grooves; first arc-shaped block pieces are arranged between the first seed discharge holes and the first seed discharge barrels, second arc-shaped block pieces are arranged between the second seed discharge holes and the second seed discharge barrels, the first arc-shaped block pieces and the second arc-shaped block pieces extend to positions below the seed groove and are hinged to first connecting rods and second connecting rods, the other end of each first connecting rod and the other end of the corresponding second connecting rod are hinged onto a lower draw bar, and a return spring is arranged between the lower draw bar and the bottom of the seed groove. The plot seed sowing device has the advantages that the plot seed sowing device is simple in structure and convenient to operate, double rows of seeds can be sown at each procedure owing to the corresponding double seed discharge barrels, and accordingly the seed sowing efficiency can be effectively improved; the plot seed sowing device is particularly suitable for sowing seeds in test plots.

Description

technical field [0001] The invention belongs to the field of seeding devices, and specifically provides a plot seeding device. Background technique [0002] During the experimental sowing of crops such as soybeans and mung beans, due to the high requirements on the row-to-plant spacing for sowing, and when it comes to the research of germplasm resources, the number of germplasm copies is large, and the large seeders used in production cannot meet the experimental sowing requirements of the plot. . At present, there are some seeding devices for sowing in experimental plots, but when the number of germplasm shares is large, the preliminary preparation work is relatively long, and it is necessary to change the seed box several times during the sowing process, which is prone to errors. In addition, due to the small area of ​​the test land in many places in the southern region, large machines cannot enter, so the original manual sowing can only be used, that is, use the sowing r...

[0002] During the experimental sowing of crops such as soybeans and mung beans, due to the high requirements on the row-to-plant spacing for sowing, and when it comes to the research of germplasm resources, the number of germplasm copies is large, and the large seeders used in production cannot meet the experimental sowing requirements of the plot.

At present, there are some seeding devices for sowing in experimental plots, but when there are many germplasm copies involved, the preliminary preparation work is relatively long, and it is necessary to change the seed box several times during the sowing process, which is prone to errors

In addition, due to the small area of ​​the test land in many places in the southern region, large machines cannot enter, so the original manual sowing can only be used, that is, use the sowing ruler to place it in the opened row ditch, and sow the seeds according to the scale. This method is labor-intensive. and inefficient
