A kind of corn seed selection and seed dressing equipment

Abstract

The invention discloses a kind of corn seed selection and seed dressing equipment, which includes a feeding system, a photodetection system, a screening system, a moving system, a spraying system, a drying system, a coating system, and a solid seed dressing system; During the seeding process, the damage to the corn seed material is minimal, and the skin of the seed material will not be damaged. The loss rate of raw materials is low, the seed selection effect is good, and the seed selection efficiency is greatly improved. The equipment of the present invention can not only detect whether the outer structure of the corn seed material is damaged, but also detect and identify the color and overall plumpness of the corn seed material, so as to realize the effective detection of whether the seed material itself has diseases. The equipment can realize the double seed dressing process of the corn seed material, the seed dressing effect is uniform, and the use effect of the seed material after seed dressing is good, which eliminates the burden of the second seed dressing on the farmer and effectively prevents the farmer from doing the seed dressing operation by himself Adverse consequences of non-compliance.

Description

technical field [0001] The invention relates to the field of corn planting technology and equipment, in particular to corn seed selection and seed dressing equipment. Background technique [0002] With the rapid development of the national economy, people's living standards are improving day by day, and people's pursuit of quality of life is higher. Among them, the requirements for diet have increased from the original basic dietary requirements to all-round healthy dietary requirements. Compared with traditional grain crops such as rice and wheat, corn has strong drought tolerance, cold tolerance, barren tolerance and excellent environmental adaptability. Corn has high nutritional value and is an excellent food crop. As a high-yield grain crop in China, corn is an important source of feed for animal husbandry, aquaculture, and aquaculture, and is also one of the indispensable raw materials for food, medical and health, light industry, and chemical industry. Because corn r...

Problems solved by technology

[0003] At present, the following problems are prone to occur in the corn planting process, especially at the source: too many impurities in the original corn seed material, the seed material is low in plumpness or even severely damaged, and it is necessary to add additional pest control and fertilization fillers during the corn sowing process and other additional operations, resulting in a decrease in planting efficiency and an increase in cost

Therefore, it is necessary to properly select and dress corn seeds, but most of the existing equipment in this area has the following problems: (1) Most of the selection process uses a drum-type scheme for seed selection, which Although this kind of physical seed selection method will have higher screening rate and screening accuracy, it is extremely easy to cause the seed material to wear and tear the outer skin or even break during the forward process of transmission, which on the contrary leads to a substantial increase in the loss rate of raw materials; (2 ) Most of the screening and detection of corn seed materials in the current equipment is limited to whether the outer layer structure is damaged, etc., and the color and luster of the seed materials are rarely detected and identified, so it is impossible to effectively detect whether the seed materials themselves have diseases in real time; (3 ) Most of the current equipment can only complete the seed dressing once, because the seed dressing effect is generally or even poor, and even the farmers need to carry out the second seed dressing by themselves. On the one hand, the seed dressing effect is easy to appear in the seed dressing process Evenly, on the other hand, due to the lack of seed dressing procedures, the use of seed materials after seed dressing is not good. For example, many farmers also need to carry out solid seed dressing by themselves to mix certain fertility substances into the seed materials to improve the corn yield after sowing. The effect of absorbing fertility, and because most of the self-dressing process uses physical mechanical stirring, it is easy to damage the seed material
