The invention belongs to the technical field of seeders, and particularly relates to a four-connecting-rod mechanism for a seeder. The four-connecting-rod mechanism comprises two first connecting rods, fixing plates are fixedly mounted at the sides, away from each other, of the two first connecting rods, one same first cylinder is fixedly mounted on the two first connecting rods, and the first cylinder penetrates through the two first connecting rods; second connecting rods are fixedly mounted at the two ends of the first cylinder correspondingly, one same second cylinder is fixedly mounted onthe two first connecting rods, the second cylinder penetrates through the two first connecting rods, and third connecting rods are fixedly mounted at the two ends of the second cylinder correspondingly; and the sides, close to each other, of the two third connecting rods are fixedly provided with one same first round rod, one same second round rod and one same third round rod. The four-connecting-rod mechanism is high in practicability; and the four-connecting-rod mechanism can be adjusted according to different sown soil properties, the four-connecting-rod mechanism can be suitable for soilwith different soil properties, the connecting relation between all components is tight, and it is guaranteed that all the components cannot shake in the using process.
Description
technical field [0001] The invention relates to the field of seeder technology, in particular to a four-bar linkage mechanism for a seeder. Background technique [0002] The seeder is a common agricultural equipment that plays a vital role in the cultivation of crops such as wheat and corn. The seeder usually consists of multiple sowing single groups arranged side by side, which can realize simultaneous sowing of multiple rows. But in some special cases, it is necessary to make a sowing single group leave the ground so that it can be stopped. For this reason, it is necessary to set up corresponding lifting devices. [0003] After retrieval, the authorized publication number is CN109168469A, which discloses a four-bar linkage mechanism for seeders, including a front frame, an upper rod and a lower link, one end of the upper rod is hinged to the upper end of the front frame, and one end of the lower link is Hinged with the lower end of the front frame, the front frame is hi...
