technical field

The invention relates to a packaging machine, in particular to a packaging machine for orientation treatment of corn seeds.

Background technique

Corn is the second largest grain crop in my country. The planting area and output account for 26% and 30% of the grain crops respectively. It occupies a dominant position in my country's grain production. In 2020, my country will add 100 billion catties of grain, 60% of which will be achieved by corn. The improvement of its mechanized operation level plays a very important role in the stable and high yield of corn in the future and in ensuring food security. With the transfer of our country's labor force and the acceleration of the pace of modern agriculture, it is imminent and imperative to realize the mechanization of the whole process of corn production. The Ministry of Agriculture proposed the measures of "four increases and one reform", mainly to increase the yield of corn and increase the planting density. However, some of the current varieties are not suitable for increasing density.

Oriented cultivation of corn is to orient the embryos of corn seeds in a direction perpendicular to the planting row. During the growth period of corn, the leaves of corn are perpendicular to the planting row, and the ears are also oriented in the same direction, optimizing the lighting structure of the plant and increasing the effective leaf area. Appropriately increasing the density is conducive to the effective use of light, heat and air resources in the field, so as to achieve the purpose of increasing the yield per unit area. In addition, due to the consistent growth of corn and the same orientation of corn ears, it is beneficial to realize the mechanization of harvesting and reduce the loss of machine harvesting.

At present, most of the directional sowing methods of corn at home and abroad are carried out manually, and there is no mature technology and automatic equipment. Therefore, it is imperative to study such a machine, which has theoretical and practical significance.
