Description
Technical Field
The invention relates to the technical field of agricultural planting, in particular to an intelligent agricultural sowing machine.
Background
Sowing is a basic link of agriculture, and the quality of sowing affects the rate of emergence later. Seeds of most plants can be directly sown in the field, and for the seeds with weak seedlings, seedlings are required to be firstly sown in a seedbed, and a plug seedling mode is mostly adopted. The hole tray seedling raising technology is a modern seedling raising technology which adopts light-matrix soilless materials such as turf, vermiculite and the like as seedling raising matrixes, adopts hole trays as seedling raising containers, mechanically performs precision seeding, one hole by one hole during hole tray seedling raising seeding, and once seedlings are formed.
The plug seedling can provide high-quality seedlings for transplantation, but vegetable seeds and the like belong to small-grain-size seeds, and the average diameter is less than 3 mm. The physical characteristics of seeds with different small grain sizes, such as geometric shapes, are different, and are difficult points and key points for developing precision seed metering devices. The mechanical precision seeding apparatus researched by foreign scholars in early days is characterized in that seeds are separated from a seed box by using holes according to the size and the grain type of the seeds and are arranged in order, and then the seeds are sowed. The mechanical precision seed sowing device has a good effect on sowing seeds with large and medium particle diameters such as corn, soybean and wheat, but the mechanical seed sowing device has low sowing speed and strict requirements on seed appearance, when sowing seeds with small particle diameters, the seeds are easy to block and damage due to too small holes, and when the seeds are too large, single-seed sowing is difficult to realize. The pneumatic seed sowing device separates seeds from a seed box by using pneumatic force, and the seeds are adsorbed and arranged on a seed sowing plate and then sowed. In contrast, the pneumatic seed sowing device has low requirements on seed shape and high sowing precision, and is vigorously developed and fully applied in recent years.
However, in the prior art, for seeds with small particle size, because the volume and the mass of the seeds are small, one seed suction hole is likely to suck a plurality of seeds under the action of negative pressure, so that a plurality of seeds are sown on one plug tray, the seeds are wasted, the cost is increased, and even the normal seedling culture in the later period is influenced; in addition, the seeds cannot be accurately absorbed when being sucked under negative pressure, so that the situation of air suction exists in a certain or some seed sucking holes, the seeds cannot be sown in the hole tray, and the precision sowing cannot be realized.
