A cyperus oleifera seeding machine

Technical Field

The invention relates to the field of agricultural seeders, in particular to a cyperus oleifera seeder.

Background Art

Cyperus oleifera (also known as tiger nut) is native to Africa and Mediterranean coastal countries. It is an annual plant of the Cyperaceae family and has strong adaptability. It was introduced to China and planted in Heilongjiang, Beijing, Hebei, Hunan, Shandong, Sichuan and other places. It is a high-quality, high-yield, and new type of oil and grain crop with high comprehensive utilization value. It is also known as Shantui grass and is also an ornamental plant for beautifying and greening the environment. This variety has strong adaptability and high yield. Generally, it produces 1000 kg of fresh beans and 500 kg of dry beans per mu. Planting 1 mu of Cyperus oleifera is equivalent to 7 to 10 mu of rapeseed. The leaves are needle-shaped, thin and long, the plant height is about 1 meter, it grows vigorously, has strong tillering ability, and produces tubers underground. Cyperus oleifera is an annual plant of the Cyperaceae family. It was introduced from Africa by my country's agricultural research departments a few years ago.

The soil entering the covering wheel is discharged from the other edge of the covering wheel under the action of the rolling of the spiral inner ribs, and the position corresponding to the other edge of the covering wheel is the middle part of the mulch film, so that the soil on the edge of the mulch film is transported to the middle of the mulch film, and the middle of the mulch film is covered, so that the wind resistance of the first mulch film is stronger and it is not easy to be blown away by the wind;

The specific function of the vibration soil cleaning device is to knock the outer wall of the covering wheel, and the soil adhered to the inner wall of the covering wheel falls off under the action of vibration.

Working principle and process of the present invention:

When in use, the seeder is connected to the external tractor through a traction rod, and then the hydraulic cylinder is connected to the hydraulic circuit of the tractor, and hydraulic oil is injected into the hydraulic cylinder by the external hydraulic system to extend the hydraulic rod of the hydraulic cylinder, lift the entire main frame, and make the fertilization disc furrow opener, sowing furrow opener, soil divider, mulch film positioning device and mulch film covering device arranged on the frame rise and leave the ground at the same time as the main frame, and the seeder is transported to the land to be sown through the tractor, and then the hydraulic rod of the hydraulic cylinder is retracted, and the entire main frame falls, so that the fertilization disc furrow opener, sowing furrow opener, soil divider, mulch film positioning device and mulch film covering device arranged on the frame fall at the same time as the main frame, fill the fertilizer box with fertilizer, fill the sowing box with seeds, install the drip irrigation belt on the drip irrigation belt bracket, install the mulch film on the mulch film bracket, adjust the positions of the fertilization disc furrow opener, sowing furrow opener, soil divider, mulch film positioning device and mulch film covering device, and then start the tractor for sowing, and it can also be adjusted according to actual needs during the sowing process.

Beneficial effects of the present invention:

The invention has the advantages of simple structure, convenient operation, safety and reliability, and solves the problems of standardized field planting and standardized field management of cyperus oleifera, and can simultaneously complete sowing, film covering, laying of drip irrigation tape, etc., thereby improving sowing efficiency and providing a reliable basis for standardized field planting and standardized field management of cyperus oleifera.
