Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a seed drill pressing wheel with conveniently adjustable use height. Background Art

[0002] A seeder is an agricultural machinery equipment used for sowing crop seeds. It can improve sowing efficiency and ensure uniformity and accuracy of sowing. There are various types of seeders, including grain drills, corn hole seeders, etc. A pressure wheel is needed when the seeder is sowing. The seeder pressure wheel is an important component of the seeder and is mainly used to compact the soil to ensure that the seeds can grow better.

[0003] After searching, the patent number is CN112400414A, and the name is an invention of a seed drill pressing wheel with an anti-winding mechanism, including a pressing wheel. Through research and analysis, it is found that although the advantage of cutting the dry weeds entangled on the shaft is achieved, the following disadvantages still exist to a certain extent.

[0004] For example, because it does not have the function of conveniently adjusting the height during use, the soil cannot be compacted according to the required compaction height, which affects the effect of sowing and compaction. In addition, it does not have the function of scraping the surface of the compaction wheel. Therefore, when the compaction wheel is rolling and compacting, mud is easily adhered to the surface, which is not conducive to the compaction of the compaction wheel. In order to solve the above technical problems, we have designed a seeder compaction wheel with easy-to-adjust use height. Utility Model Content
