Broadcaster for vegetable seed sowing

Abstract

The invention discloses a broadcaster for vegetable seed sowing, comprising a frame. Positioning seats are arranged on the two sides of the bottom of the frame; a universal wheel is arranged at each end of each positioning seat; the center of the frame is of cavity structure; a moving rack is arranged above the cavity structure and is provided with a seed chamber; the top of the seed chamber is provided with a feed port; the bottom of the seed chamber is provided with a plurality of broadcasting tubes; a discharge port is arranged between the upper ends of the broadcasting tubes and the bottomof the seed chamber; the lower ends of the broadcasting tubes penetrate the moving rack; the lower ends of the broadcasting tubes are fitted to the center of the frame; the lower end of each broadcasting tube is provided with an outlet; the middle of each broadcasting tube is provided with a control switch; the frame is provided with a plurality of hydraulic cylinders; the front of each hydrauliccylinder is provided with a piston rod horizontally arranged; the front end of each piston rod is fitted to the lateral side of the moving rack; the lateral side of the frame is provided with a nutrient liquid supply system. The broadcaster for vegetable seed sowing allows vegetable seeds to be adjusted finely in the transverse direction, so that vegetable seed broadcasting efficiency is improvedgreatly.

Description

technical field [0001] The invention relates to a seeding device, in particular to a seeding device for sowing vegetable seeds. Background technique [0002] Seeder is a planting machine that takes crop seeds as the sowing object. Seeders used for a certain type or certain crops are often named by the name of the crop type, such as grain drills, corn hole seeders, cotton seeders, pasture spreaders, etc. The sowing machine is a sowing machine that distributes the scattered seeds evenly on the sowing field. The commonly used model is the centrifugal spreader, which is attached to the rear of the agricultural transport vehicle. Consists of a seed box and a spreading wheel. The seeds fall from the seed box onto the sowing wheel, and are broadcast along the tangential direction under the action of centrifugal force, with a broadcast width of 8 to 12 meters. It can also spread powdered or granular fertilizers, lime and other materials. The spreading device can also be install...

AI Technical Summary

Problems solved by technology

The existing seeder is inconvenient to sow vegetable seeds, and it is inconvenient to fine-tune the sowing position of the sown vegetable seeds in the farmland, and it does not have the function of supplying and transporting nutrient solution, so the sowing efficiency is low
