Abstract
The utility model discloses a seeder with a seed sowing device for vegetable, which makes use of a four-bevel cavity; the longitudinal direction and the longitudinal direction at the bottom of the cavity body are evenly provided with taper projections, and the tops of the projections are provided with through holes. The top of the cavity body is communicated with a tee joint, and one opening of the tee joint is connected with a flexible pipe with a negative pressure air source. When fingers are used for blocking the decompression opening of the tee joint, the cavity of the four-bevel cavity generates negative pressure. The through holes with convex bottom faces are respectively adsorbed with a seed, and the four-bevel cavity is placed inside a seedling tray. When the decompression opening is opened, the attracting force of the negative pressure disappears. The seed is evenly sown to the seedling tray. The seeder is suitable for the sprouting and seedling of vegetable seeds.
Description
The utility model belongs to the agricultural machinery class.
For the output that improves vegetables with shorten planting season, generally adopt the method for balled transplanting, seedling in the greenhouse earlier just, and then be transplanted in the vegetable plot and go, the method of seedling in the greenhouse, be with in the seed broadcasting of seed or the vernalization soil in the seedling dish, wait to grow behind the rice shoot more separately being transplanted in the vegetable plot of individual plant and go.This mode that scatters seeds in the seedling dish, its weak point are uneven irregular, and intensive place rice shoot is elongated, easily pulls apart shoot root when plant division is transplanted again.
The purpose of this utility model is: a kind of line-spacing and uniform seeding unit of spacing in the rows sowed in seedling is provided.
The technical solution of the utility model is: a truncated rectangular pyramids cavity is arranged, horizontal, vertical uniform tapered protrusion is arranged on the bottom surface of cavity, each convex top has through hole; Threeway of the top UNICOM of truncated rectangular pyramids cavity, a port in the threeway connects one and the joining flexible pipe of negative pressure source of the gas.
Fig. 1 is a structural representation of the present utility model.Fig. 2 is a partial view.
4 is truncated rectangular pyramids cavitys among the figure, can adopt plastics or galvanized sheet to make, and horizontal, vertical uniform tapered protrusion 5 is arranged on the bottom surface of cavity, and each convex top has through hole; Adopt horizontal 30, vertical 30 convexities are fit to the specification of existing seedling dish; Threeway 2 of the top UNICOM of truncated rectangular pyramids cavity, a port in the threeway connects one and the joining flexible pipe 1 of negative pressure source of the gas, for easy to use, two hooked hands 3 is arranged on the tube wall of threeway.(see figure 2).
During use, catch on hooked hand 3 with two fingers, a finger is blocked relief port C, makes in the truncated rectangular pyramids cavity and produces negative pressure, and truncated rectangular pyramids cavity 2 is put in the seed pan, make the through hole on each tapered protrusion 5 on the cavity bottom surface adsorb a seed respectively, then with cavity 4 handlings in the seedling dish, finger is opened the relief port, negative pressure in the cavity 2 disappears, through hole on the tapered protrusion 5 also disappears to the absorption affinity of seed thereupon, and seed is laid down uniformly in the soil of seedling dish.
This feed mechanism for seed has sowing evenly, is particularly suitable for the sowing of vernalization kind, and Miao Qimiao is strong because sowing evenly, has, the good effect that is difficult for hindering root, increases output is transplanted in plant division.
