AI Technical Summary
The existing rotary tillage seeders have uneven soil at the double ridge joints, which increases operational resistance.
A disk-shaped rake sheet is installed in the front of the rotary tillage system of the rotary tillage seed machine to form a figure-eight-shaped structure. The front side plate bulls the soil into the rake sheet groove to reduce soil accumulation and rolling support through the support shaft to reduce operation resistance.
The soil leveling at the double ridge joints has been achieved, which significantly reduces the resistance to rotary tillage and sowing operations and improves operation efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a soil harrowing structure of a rotary tillage seeder. Background Art
[0002] Installing a rotary tillage seeder on agricultural machinery can realize the integrated operation of rotary tillage and sowing, and improve the efficiency of farmland operations. The rotary tillage seeder performs rotary tillage in the front, sowing in the back, and suppressing. The rotary tillage seeder includes a rotary tillage system; the rotary tillage system includes a horizontally flat front support frame, and front side plates that are respectively fixedly connected to both sides of the front support frame and are longitudinally and vertically arranged in the front and rear directions (the movement direction of the rotary tillage seeder is the front and rear direction); a rotary tillage device is provided under the front support frame. When the rotary tillage seeder is performing rotary tillage, the soil in front of the front side plate is piled up when the front side plate moves forward. First, the ground at the joint of the double ridges is uneven after the operation, and second, the resistance to the rotary tillage and sowing operation is increased. Summary of the invention
[0003] Aiming at the deficiencies of the prior art, the utility model provides a double-ridge joint harrowing structure of a rotary tillage seeder, which can level the soil at the double-ridge joint during rotary tillage operation and significantly reduce the resistance of rotary tillage and sowing operation.
[0004] The utility model achieves the technical objectives through the following technical solutions.
[0005] The double-ridge joint harrowing structure of a rotary tillage seeder is arranged at the front part of the rotary tillage system of the rotary tillage seeder; the rotary tillage system comprises a horizontally flat front support frame, and front side plates respectively fixedly connected to both sides of the front support frame, longitudinally and vertically arranged in the front and rear directions (the movement direction of the rotary tillage seeder is the front and rear direction); a rotary tillage device is arranged below the front support frame; the improvement lies in that: disc-shaped harrow blades are respectively arranged in front of the two front side plates; the front side plates and the disc-shaped harrow blades are connected by a supporting seat, and the rear end of the supporting seat is fixedly connected to the front end of the front side plate; the two disc-shaped harrow blades are arranged opposite to each other; the centers of the back sides of the two disc-shaped harrow blades are respectively provided with supporting shafts with horizontal central axes and coaxial with the central axes of the disc-shaped harrow blades; the central supporting shafts on the back sides of the disc-shaped harrow blades are rollingly supported at the front end of the supporting seat.
[0006] Furthermore, the two disc-shaped rake blades are in an eight-shaped shape facing forward.
[0007] Furthermore, one side of the two disc-shaped rake blades facing each other is concave.
[0008] Compared with the prior art, the utility model has the following positive effects:
[0009] 1. Disc-shaped harrows are respectively provided in front of the two front side plates. When the rotary tillage seeder is in operation, a groove is cut in front of the front side plates. When the front side plates move forward, the front side plates push the soil into the grooves formed by the disc-shaped harrows in front, so that soil accumulation will not be formed, the soil at the joints of the double ridges is leveled, and the resistance of rotary tillage and sowing operations is significantly reduced.
[0010] 2. The two disc-shaped harrow blades are shaped like an eight toward the front, and the harrowing area is large, which further improves the soil flatness at the joints of the double ridges and further reduces the resistance of rotary tillage and sowing operations.
