Description

Technical Field

[0001] The utility model relates to the technical field of a feeding device of a seeder, in particular to an anti-blocking feeding device of a seeder. Background Technique

[0002] A seeder is a planting machine with crop seeds as the sowing object. For a seeder for a certain type or kind of crop, it is often named after the crop type, such as a grain drill, a corn hill-drop planter, a cotton planter, a forage broadcaster, etc.

[0003] The existing patent number (CN 205305390 U) discloses an anti-blocking feeding device of a seeder, which includes a feed bin, a crankshaft, a ball head rotating pair, and a sprocket. The crankshaft is correspondingly arranged inside the feed bin. One end of the crankshaft extends out of the end face of the feed bin and is provided with a sprocket, and the other end face is provided with a connection hole. The rotating shaft of the ball head rotating pair is correspondingly assembled in the connection hole, and the ball head part of the ball head rotating pair extends out of the end face of the feed bin. A receiving base is correspondingly arranged on the outer wall of the feed bin for the ball head rotating pair; several crank arms are arranged in the middle of the crankshaft, and the crank arms are correspondingly arranged above the feeding port of the feed bin; the device has a simple structure and is convenient to use. By setting the crankshaft connected to the driving mechanism of the seeder, as the crankshaft rotates, the crank arms of the crankshaft continuously stir the seeds above the feeding port, making the seeds more fluffy and the feeding smoother, which greatly ensures the feeding quality of the seeder. However, in the actual use process, it is not easy to screen and filter the seeds entering the feeding device of the seeder. Large impurities and gravel in the seeds are easy to enter the inside of the seeder and cause blockage and damage to the inside of the seeder. Therefore, we introduce a new anti-blocking feeding device of a seeder. Summary of the Utility Model
