Agricultural wheat precision seeder

    Wheat Seeder seeding machinery with precise seeding speed, row spacing and depth. It has the advantages of saving seeds, eliminating the post-emergence thinning operation, and making the nutrient area of each crop uniform. Most of them are single-grain hole seeding and multi-grain hole seeding, and the number of grains per hole is precisely controlled. It is generally improved on the basis of various seed metering devices of the hole seeder. For example, improve the shape and size of the hole pattern on the sleeve wheel seed metering device so that it only accepts one seed to prevent cavitation; directly connect the seed metering device with the opener or place it in the opener to reduce sowing high. , Multifunctional Wheat Planter controls the falling speed of the seeds to avoid the seeds from bouncing; install the vertical disc type seed thrower on the horizontal disc seed metering device, change the sowing direction, reduce the sowing height, and avoid the seed displacement; in the double disc type ditching In the middle, the device is attached with a depth-limiting wheel at the same position to ensure stable seeding depth. The multi-seed Precision Seeding Machine is equipped with a hole-type hole-forming mechanism between the seed-metering device and the hole-opener, so that the single seeds discharged from the seed-metering device can be collected into a precise number of seed groups in the hole-type hole-forming mechanism. , and then sown into the seed furrow. In addition, some new structures have been developed, such as the use of paper tapes that presow single seeds at regular intervals,
