Description
Technical Field
[0001] The utility model relates to the field of agricultural tillage machinery, in particular to a seeder. Background Art
[0002] A seeder is a modern agricultural machinery, mainly used for sowing crops in strip fields that have been sorted and leveled. This type of seeder integrates multiple functions, such as tillage, fertilization, and sowing, which can effectively improve agricultural production efficiency, reduce labor intensity, and ensure sowing quality. It is suitable for large-scale, standardized farmland operations.
[0003] The existing seed drill mainly consists of a tractor, a connecting mechanism, a rotary tillage stubble remover and a precision seeding machine. The tractor drives the rotary tillage stubble remover and the precision seeding machine through the connecting mechanism to move on the land. The rotary tillage stubble remover near the tractor loosens the land and removes the straw covering the land surface, while the precision seeding machine at the rear completes the seeding and fertilization operations. Although this farming method is efficient, when planting on flat ground and covering the soil, the seeds and straw will be buried together, affecting the close contact between the seeds and the soil, thereby hindering the seeds from absorbing water and swelling and normal germination, and to a certain extent reducing the seed emergence rate.
[0004] Therefore, it is necessary to provide a strip field ridge-forming seeder to solve the above-mentioned technical problems. Utility Model Content

The angle between the two arc-shaped plates in the forward direction of the tractor is an advantageous angle. The intersection of the front blades of the two arc-shaped plates is fixedly connected to the lower part of the support assembly.
[0010] Preferably, the bottom of the front blade extends downward and outward along the tangent of the arc surface to form a blade for trenching the land, and the rear side of the front blade is connected to the rear wing part for pushing the land outward to both sides to form ridges. In this way, trenching and ridge formation on the land can be completed conveniently.
[0011] Preferably, the support assembly includes a vertically arranged support block, the bottom end of which is fixedly connected to two arc-shaped plates; the top end of the support block is fixed to the bottom of the connecting mechanism through a clamp fitting. Thus, the position of the ridging mechanism can be adjusted according to actual use requirements, which is convenient for maintenance and replacement.
[0012] Preferably, the clamp fitting comprises a concave frame arranged at the top end of the support block, and a square piece matched with the opening of the concave frame is provided on one side of the concave frame.
[0013] Preferably, the connecting mechanism includes a support frame, which is arranged on the rear side of the rotary tillage stubble collector away from the tractor, and a plurality of movable parts are provided between the rotary tillage stubble collector and the support frame, one side of the movable parts respectively slides and extends into the interior of the rotary tillage stubble collector, and the side of the movable parts away from the rotary tillage stubble collector respectively slides and extends into the interior of the support frame, and the concave frame is slidably sleeved on the outer surface of the support frame.
[0014] Preferably, the movable part includes a movable block, and movable grooves are respectively opened on the adjacent sides of the rotary tillage stubble collector and the support frame. The movable block is embedded in the movable groove, and the rotary tillage stubble collector and the support frame are connected through the cooperation of the movable block and the movable groove.

When the staff starts the tractor for cultivation, the tractor drives the rotary tillage stubble remover, the ridging mechanism and the precision seeding machine to move, and the two arc plates of the ridging mechanism move on the land to complete furrowing and ridging.
[0018] The two arc-shaped plates are inserted into the soil through the front blades, and grooves are drawn on the land through the two arc-shaped plates. At the same time, because the two arc-shaped plates intersect and form an advantageous angle, the two arc-shaped plates will plow the straw to the ridges when plowing the land, and push the straw to the side of the ridges away from the long groove, effectively preventing the straw from falling into the long groove after the two arc-shaped plates leave, avoiding contact with the seeds, and preventing the straw from hindering the seeds from absorbing water, swelling and normal germination. In addition, during subsequent fertilization and watering, the seed planting position can be known, and accurate management and maintenance can be carried out to improve the seed germination rate.
