Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural planting equipment, in particular to a seeder. Background Art

[0002] Corn planters refer to planting machines that plant corn seeds. When using existing corn planters, due to external factors, the planter cannot automatically stop sowing when the planter needs to reverse, resulting in seed waste. In addition, the planter in the prior art cannot compact the ground after sowing, resulting in some seeds not being able to come into close contact with the soil, affecting the growth of the seeds.

[0003] For example, a corn seeder with patent application number CN202322377142.7 discloses "including a frame; a first rotating shaft, the first rotating shaft is rotatably arranged on the frame; a grounding wheel mechanism, the grounding wheel mechanism drives the first rotating shaft to rotate, and the grounding wheel mechanism is arranged on the frame; a one-way transmission mechanism, the first rotating shaft drives the one-way transmission mechanism to transmit; a seeder, the seeder is arranged on the frame, and the one-way transmission mechanism drives the seeder. Through the above technical solution, the problem in the prior art that the seeder cannot stop sowing when reversing during sowing is solved. Seeds are wasted, and the furrow opener is easily blocked and needs to be cleaned regularly, which affects the sowing efficiency. "Although the above structure can realize the sowing of corn, the above device does not have a technical solution and technical inspiration for compacting the soil after sowing, which may cause some seeds to be unable to come into close contact with the soil, affecting the growth of seeds; and the above technical solution cannot realize fertilization before sowing, and it is necessary to fertilize separately before sowing, which is inefficient; and most traditional fertilizer spreaders use a pipe to discharge fertilizer on the front side of the seeding machine, which is very easy to cause the pipe to be scratched by weeds or the like when moving forward, causing damage or displacement.

[0004] In order to solve the above problems, we provide a seeder that can realize fertilization and sowing, compact the ground after sowing, and avoid problems such as damage and displacement of the fertilizer pipe during movement. Utility Model Content
