[0002] A seeder is a planting machine that sows crop seeds. It is used for a certain type of crop and is often named after the crop type, such as a grain drill, corn hole seeder, cotton seeder, forage spreader, etc.

[0003] A suspension frame is installed on the rear side of the seed drill. The cantilever of the suspension frame is fixedly connected to the plow leg through bolts or U-shaped brackets to achieve tillage. Some plow legs can adjust the angle of entry into the soil to adapt to different soils and obtain better soil entry performance, but most plow legs do not have this function. The connection between the seed drill suspension frame and the U-shaped bracket lacks a reinforcement mechanism and is prone to falling off and loosening. For this reason, we propose a common connector for the seed drill suspension frame and the plow leg. Utility Model Content

[0008] Furthermore, the anti-slip mechanism also includes an adjusting bolt, and the middle part of the threaded seat is rotatably connected to the adjusting bolt, and the adjusting bolt is respectively in contact with the side surfaces of the vertically adjacent pressure plates to lock the position of the pressure plates.

[0009] Furthermore, the anti-slip mechanism also includes a handwheel, and the outer ends of the two adjusting bolts facing away from each other are fixedly sleeved with a handwheel to facilitate the rotation of the adjusting bolts.

[0010] Furthermore, the anti-slip mechanism also includes an anti-falling bolt, the left end of the rotating shaft is plugged with an anti-falling bolt, the bolts of the anti-falling bolts are threadedly connected with nuts, and the anti-falling bolts are located on the left side of the base plate to prevent the rotating shaft from falling off.
