Description

Hole planting machine on potato film

technical field

The invention relates to the technical field of agricultural machinery, in particular to a potato film hole-opening planter suitable for dry farming areas in Northwest China.

Background technique

At present, the early mulching hole planting technology in the arid agricultural areas of Northwest China has achieved 100% coverage of ridges and mulch, which cuts off the evaporation path of exposed soil and maximizes the conservation of soil moisture. The ineffective evaporation accounting for 60%-65% of the precipitation is minimized, and at the same time, the ridges of different sizes in the field form a micro-water collection surface, so that the natural precipitation gathers in the seeding ditch and infiltrates around the crop root system along the pores, and is stored in the soil. In addition, increasing the moisture content under the film improves the water supply of the farmland and provides the water needed for crop growth. However, the potato planting area in Northwest China, especially in Gansu Province, is increasing year by year. Most potatoes are planted on hillsides and horizontal terraces, and the plots are relatively small. For a long time, potato planting in various places has been mainly done manually, and the proportion of machine-sown and machine-harvested areas is very small, accounting for only about 5% of the potato planting area.

At present, the seed metering devices for precision sowing include water disc type, cone disc type, socket wheel type, spoon wheel type, inner filling hole wheel type, suction type, etc. The seed meter of the seeder is mostly the hole wheel type and the inner filling hole wheel type. The seeding process of the socket wheel seed metering device is divided into filling, scraping, protecting and metering. When working, the seeds are filled in the socket by their own weight and rotate together with the seeding wheel. When passing through the seed scraper, the many seeds in the socket are scraped off, and the seeds left in the hole are covered by the arc-shaped seed protection plate. When the sun rises from the bottom, the seeds fall into the seed ditch by their own weight to complete the planting task. The size of the hole of the hole wheel can be designed according to the shape of the seed and the number of holes required. It has good versatility, simple structure, and high and low seeding. Advantages, but the seeds are required to be cleaned and graded as much as possible, and the seed injury rate is high during the rowing process, which is not suitable for potato seeds at all. For the roller-type duckbill punching seed meter, it is more suitable for sowing small seeds such as grains, but for the design of large potato seeds, its structure will be more complicated. There are relatively few potato film seeders in the domestic market, and the phenomenon of seed leakage is serious, and the effect of covering soil is not good, and manual re-seeding or covering is required, and the labor burden has not been completely reduced.
