Description

Hole fertilizing seeder with stable and efficient fertilizer distributor

Technical Field

The utility model relates to a hole fertilizing seeder with a stable and efficient fertilizer distributor.

Background

Mechanization is a hallmark of modern agriculture. The fertilizer is applied by adopting agricultural machinery, so that the efficiency and the labor are saved, and the fertilizer is uniformly applied. With the increasing shortage of labor force, a mechanized fertilization mode is indispensable in the future crop planting link. The fertilizer is an important agricultural production data and can improve the yield of crops in unit area. Practice shows that applying chemical fertilizer is one of the fastest and most effective production measures for increasing crop yield. According to the statistics of the Food and Agricultural Organization (FAO) of the United nations, the fertilizer accounts for about 40-60% of the total share of the fertilizer for increasing the yield of crops, and the fertilizer can improve the yield per unit of the food crops by 51.4% in developing countries. Agricultural and chemical experts at home and abroad generally think that the yield can be increased by 40-60% when the fertilizer is applied to crops under the condition that other production factors are not changed. The food production in China can obtain such a great achievement, and the increase of the application amount of the fertilizer and the continuous development of the fertilization technology are benefited to a great extent. The related data show that the amount of the fertilizer in China in 2003 is 4412 ten thousand t, 4637 ten thousand t in 2004 and 4766 thousand t is consumed nationwide in 2005. The total consumption amount and the unit area consumption amount of the fertilizer reach the top of the world. The application method of the fertilizer mainly comprises 3 kinds, namely base fertilizer, seed fertilizer and intertillage topdressing. The seed fertilizer is an important fertilizer application mode, can provide nutritional requirements for seed germination and the initial growth and development stage, and lays a foundation for later growth. The seed fertilizer application mode is divided into side deep fertilizer application, front deep fertilizer application and mixed seed fertilizer application according to different relative positions of the fertilizer and the seeds. Because the seed fertilizers in the mixed seed and fertilizer application mode are in direct contact with each other, the burning of seeds is easy to cause, the emergence rate is reduced, and the seed and fertilizer are gradually eliminated. How to apply fertilizer economically and reasonably, improve the utilization rate of the fertilizer and reduce the pollution to the environment becomes a problem which needs to be solved urgently in the current agricultural production. When the fertilizer is applied incorrectly, if the relative distance between the fertilizer and the crops is too far, the fertilizer cannot be fully absorbed by the crops, so that the fertilizer is wasted; if the distance is too close, the phenomena of seed burning and seedling burning are easily caused. In addition, the fertilizer which is not absorbed in the soil destroys the ecological environment of the soil, or is washed into rivers along with rainwater, so that the environment is polluted; the seed fertilizer application mode is that the fertilizer is applied into the soil while sowing, and the fertilizer provides nutrients for the seed germination and the plant growth initial stage. The early seed manure fertilization mode is mostly to mix fertilizers and seeds, and then to sow the mixed fertilizers and seeds by a seeder after uniform stirring. In the fertilizing mode, seeds are in direct contact with fertilizers, so that the seeds are easy to burn and burn, the emergence rate is low, the seedlings are deficient, and the seeds are gradually eliminated. At present, the application is more that the chemical fertilizer is deeply applied, the sowing and the fertilization are respectively carried out, and a soil isolation layer with a certain thickness is arranged between the seeds and the fertilizer, so that the phenomena of seed burning and seedling burning are reduced. The fertilization mode of the currently used seeding and fertilizing machine is continuous strip fertilization, the fertilizer discharging of the traditional seeding and fertilizing machine is uniform, and with the development of the accurate agricultural technology, variable fertilizing machinery can make variable decisions according to the soil formula diagram or the real-time detection data of a sensor, so that the variable input of the fertilizer is realized. In addition, the precision seeding technology is also developed rapidly, hole seeding is realized on many crops, the hole fertilizing technology is gradually paid attention, and the utilization rate of hole fertilizing materials is higher than that of strip fertilizing materials. However, some key technologies (such as hole fertilization and fertilizer discharging technologies) in hole fertilization machines are not high in level, and no mature hole fertilization and fertilizer discharging device can be used on a seeding and fertilizing machine at present. Seed fertilizer application is one of the most economic and effective fertilizer application methods, at present, most of domestic seeding and fertilizer applying machines use an external sheave type fertilizer distributor to apply fertilizer in a row, and most of the fertilizer is positioned below or right below the seed row. The drill fertilization mode can well meet the crop growth requirements aiming at drill crops, and for hole sowing crops, because the fertilizer between seed holes is difficult to absorb, the fertilizer is wasted, and the fertilizer which is not absorbed can destroy the soil ecological environment, soil hardening is caused, and the crop yield is reduced. Hole fertilization is a new fertilization method, also known as 'spot fertilization'. Putting the base fertilizer into pits dug according to the row spacing and the plant spacing; and then applying the additional fertilizer in a small pit dug at a place two to three inches away from the root of the crop. The hole digging and fertilizing method is suitable for dibbling or transplanting crops, such as corn, cotton, tomato, etc. The fertilizer is generally more concentrated than strip application, and is also more fertilizer-saving. Generally, the hole application depth is about 5-10 cm, and soil is covered after fertilization; for hole-sown crops, hole-fertilization can not only improve yield but also reduce cost. The first step of hole fertilization is to strictly screen and reasonably mix hole-fertilization materials and medicines. The fertilizer is applied by using biological organic fertilizer or biological bacterial fertilizer, and preferably fertilizer such as compound fertilizer, such as ammonium bicarbonate, ammonium sulfate, diphenylamine, etc., is not used. These fertilizers have volatility and strong pungent taste and are liable to cause damage to crops. At present, the hole fertilization can greatly reduce the planting cost, is simple to operate and is popular with a plurality of people. Meanwhile, the yield of crops is improved, the reasonable fertilizing amount can exert the advantages of hole fertilization to the maximum by adopting a reasonable method, and the problem of single planting is solved. The problem of fertilizer waste can be effectively relieved. Many researchers have proposed the normal hole fertilization mode to the precision planter, have also designed many hole fertilizing and seeding machines of different structures, but because these seeders all have some problems, do not have the mature model that is fit for popularizing and applying on a large scale. The core component of the hole fertilizing and seeding machine is a hole fertilizing and fertilizing device, and the development of a stable and efficient fertilizer device is also a difficult problem, and the technical problem is not well solved.
