Description

Technical Field

[0001] The utility model relates to the field of fertilizing machinery, and particularly relates to a subsoiling fertilizing assembly of a no-tillage seeder. Background Technique

[0002] When a no-tillage seeder sows seeds, compound fertilizers are mostly used, and the particles are relatively thick, such as diammonium phosphate, multi-element mixed fertilizers, etc. Such fertilizers contain multiple trace elements such as phosphorus and potassium, and better effects can be achieved only when they are buried deeply. After the no-tillage seeder sows seeds, there is often at least a 3 - 5-day interval until watering. This requires deep burial to reduce the volatilization of fertilizers so as to achieve better economic benefits. In existing equipment, the fertilizer leakage port is often blocked when the subsoiling teeth just enter the soil.

[0003] In some existing equipment, when there are relatively large stones in the field, the safety screw is cut off when the strong pressure spring can no longer be compressed, and the subsoiling teeth cannot be effectively protected from damage. Content of the Utility Model
