Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a seeding device. Background Art

[0002] The sizes of the seed-filling sockets on the existing socket roller type seed meter and the seed-scooping spoon on the spoon wheel type seed meter cannot be adjusted on one seed meter, so the adaptability to seeds is poor. If the seed size is large, it cannot be filled into the socket or scooped into the seed spoon, resulting in missed holes; if the seed size is small, the number of seeds filled into the socket or scooped into the seed spoon increases, resulting in reseeding and seed waste, and reduced sowing accuracy. The above problems also cause the same existing socket roller type seed meter or spoon wheel type seed meter to be unable to be used for sowing operations of different varieties of crop seeds, with a narrow range of use and low efficiency. In addition, the seeding method of the existing seed meter is mostly powered by the weight of the seed and the centrifugal force to complete the discharge from the socket or the seed spoon, which is easy to get stuck and cause failure of seed discharge. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of sowing operations, and research and design a new structure of cylindrical socket adjustable forced seeding device, so as to achieve the goals of high degree of commonality, wide range of application, strong adaptability, good seeding effect, multi-purpose of one device, and improved efficiency of device use.
