Description
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a belt type corn precision seed-metering device.
Background
The corn planting area and the total yield of China are increased year by year, but the single yield is only 1/2 of the single yield of developed countries such as America, France and the like. The main reason for high yield of American corn is that an advanced precision seeding technology is adopted, the traditional drilling is changed into hole seeding or dibbling, complete precision seeding can be achieved, and the method is very convenient for subsequent fertilization, weeding, deinsectization and harvesting. Most of corn planting in China is in a rough type, precision seeding machinery is not complete, key parts such as a seed sowing device are not reliable, a small-grain-distance uniform point drilling mode with 1.5-2 times precision seeding quantity is adopted for avoiding miss seeding, so that the seeding quantity is not accurate, the emergence rate is difficult to guarantee, and equidistant thinning is difficult.
At present, a seed sowing device for corn precision sowing in agricultural production mainly has a mechanical type and a pneumatic type, wherein the mechanical type seed sowing device is simple in structure and low in manufacturing cost, but phenomena of seed missing, seed reseeding, seed damage and the like easily occur, and the pneumatic type seed sowing device is high in operation speed and sowing precision, but is complex in structure and high in cost, and a phenomenon of large-area seed missing easily occurs when air pressure is unstable. Therefore, a sowing precision monitoring system is often additionally arranged on the sowing machine, the seed quantity of the seed box is monitored in real time by utilizing the technologies of photoelectric effect, piezoelectric effect, high-speed photography, machine vision and the like, the missing sowing rate and the reseeding rate of the seed sowing device are measured, the sowing operation effect is improved, but the timely reseeding after the missing sowing and the missing sowing during the turning of the ground can not be realized. For example, the chain-type seed sowing device with the patent number of CN2014102948244 has simple structure and low cost, but has lower operation speed and higher requirement on the shape of seeds, and can not monitor the seed leakage or the seed blockage in time; for another example, a missed seeding monitoring and positioning system and a missed seeding monitoring and positioning method of a seeder with the patent number ZL2012101441322 determine real-time position information of seeding monomers by using a differential global positioning system and draw a seeding monomer track map, although the information such as missed seeding types and missed seeding positions can be quickly and accurately determined when missed seeding occurs, the seeding cannot be timely reseeded; and as for the miss-seeding compensation system of the intelligent seeder with the patent number of CN2012106735577, when the seeding apparatus fails and can not seed, the intelligent pneumatic seed shooting compensation system is started to continue seeding, but the compensation system pneumatically needs certain conditions and time, the phenomenon of broken strips is easy to occur, and the structure of the seeding apparatus limits the great promotion of the seeding speed.
Therefore, a seed sowing device capable of monitoring the operation condition of the seed sowing device in real time is urgently needed to overcome the phenomena of seed missing and seed supplementing failure in the existing mechanical seed sowing device, so that the precision seeding of the corn is completed, and the seeding operation precision and the operation efficiency are improved.
