Wheat Pneumatic Acceleration Sowing Device

Abstract

The invention belongs to the technical field of agricultural machinery and particularly relates to a pneumatic accelerated shoot-sowing apparatus, comprising a seed discharge mechanism, a pneumatic mechanism and shoot-sowing tube (8). Wheat seeds discharged from the seed discharge mechanism are accelerated and shot into soil via the shoot-sowing tube (8) under the action of the pneumatic mechanism. Non-contact high-pressure pneumatic continuous shoot sowing is adopted herein; wheat seeds are accelerated by a high-pressure air flow and shot into soil; a sowing component is not in contact with soil so that adhesion is avoided, and disturbance upon soil and operational resistance are decreased. The pneumatic accelerated shoot-sowing apparatus is suitable for no-tillage sowing of wheat in a wheat-rice rotation region with no straw covering.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a pneumatically accelerated seeding device for wheat. Background technique [0002] Wheat is the second largest grain crop in China. The middle and lower reaches of the Yangtze River are the main grain production bases in my country. They are rich in light and heat resources, abundant in rainfall, and high in groundwater levels. The growth of wheat is less limited by water resources, and it is the area with the greatest potential for increasing wheat production in China. . Rice-wheat rotation is the main planting mode in this area. Since the rice-wheat rotation is used as a paddy-dry crop rotation, the soil texture is sticky and wet after harvesting the previous crop of rice, and there is more rainfall in the area before the sowing of the subsequent crop of wheat. When the tool parts come into contact with the soil, problems such as serious soil adhesio...

Problems solved by technology

Rice-wheat rotation is the main planting mode in this area. Since the rice-wheat rotation is used as a paddy-dry crop rotation, the soil texture is sticky and wet after harvesting the previous crop of rice, and there is more rainfall in the area before the sowing of the subsequent crop of wheat. When the machine tool parts contact with the soil, serious soil adhesion and increased operation resistance will occur, which will bring serious difficulties to the mechanized no-tillage sowing operation of wheat in the rice-wheat rotation area.

[0003] The soil moisture in rice stubble fields is complex, and foreign large-scale wheat mechanized planting equipment cannot meet the needs of small plots and wet clay soil. Rotary tillage and sowing type rice stubble and wheat seeding machinery are mainly used. When rotary tillage before sowing, the tillage resistance, soil adhesion and energy consumption are high, and the soil thrown after rotary tillage cutting is easy to stick into lumps, causing wheat to be sown on sticky soil. Agglomerated soil surface causes dry seeds, weak seedlings after sowing, increased operating costs and poor seeding quality
