Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a sowing unit. Background Art

[0002] Installing a rotary tillage seeder on agricultural machinery can realize the integrated operation of rotary tillage and sowing, thereby improving the efficiency of farmland operations. The existing rotary tillage seeder includes a seeder unit, which includes a seeder unit support plate, a furrowing structure, and a sowing pipe. The support plate is vertically arranged in the front and back directions. The rear of the seeder unit support plate is fixedly connected to a rectangular furrowing structure, and the sowing pipe is obliquely inserted into the hole of the rectangular furrowing structure. The main defect of this seeder unit is that when in use, the rectangular furrowing structure of the seeder unit drags in the soil, resulting in large forward resistance. When encountering weeds, the rectangular furrowing structure pushes the weeds at the front forward, resulting in even greater forward resistance. At the same time, the ground through which the weeds are pushed is concave and uneven, resulting in poor ground flatness after the rotary tillage seeder is operated and poor sowing quality. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the utility model proposes a disc seeder unit for a rotary tillage seeder, which significantly reduces resistance during sowing and can significantly improve the flatness of the ground and the sowing quality after the rotary tillage seeder is operated.

[0004] The utility model achieves the technical objectives through the following technical solutions.

[0005] The disc seeder unit of the rotary tillage seeder is arranged in the sowing system of the rotary tillage seeder; the improvement thereof is that it comprises a seeder unit support plate, a fastening hoop, two discs, two disc connecting shafts, two bearing seats, two second bearings, and two seed guide side plates; the seeder unit support plate is arranged vertically in the front and rear directions (the movement direction of the rotary tillage seeder is the front and rear direction) and is fixedly connected to the bottom of the fastening hoop; the central axis of the bearing seat is horizontally flat; the two sides of the seeder unit support plate are symmetrically arranged: the bearing seat is fixedly connected to the seeder The second bearing is supported in the inner hole of the bearing seat at the lower side of the seeder unit support plate, and the disc connecting shaft is supported in the inner hole of the second bearing. The disc is vertically arranged front and back and fixedly connected to the end of the disc connecting shaft away from the seeder unit support plate; the two discs are spaced apart and separated in an eight-shaped shape from front to back; the rear parts of the two seed guide side plates are respectively fixedly connected to the upper part of the two side surfaces of the seeder unit support plate, and the front parts of the two seed guide side plates are combined, and the joint part is provided with a conduit that is inserted backward and downward between the two discs.

[0006] Furthermore, the two discs are separated in an eight-shaped pattern from the front lower portion to the rear upper portion.

[0007] Furthermore, outer sides of the two discs are respectively provided with outer scrapers, the rear portion of the seeder unit support plate is fixedly connected to the outer scraper support plate, and the outer scraper is fixedly connected to the side surface of the outer scraper support plate.

[0008] Furthermore, an inner scraper is provided between the two discs.

[0009] Compared with the prior art, the present invention has the following positive effects:

[0010] 1. The two discs are spaced apart from each other and separated in an eight-shaped shape from front to back. The catheter is inserted between the two discs. When in use, the two discs are grooved to separate the soil, and then sowing is carried out through the catheter. The two discs roll forward and can cut off weeds or press them into the soil when encountering weeds, which significantly reduces resistance during sowing and can significantly improve the ground flatness and sowing quality after the rotary seeder is operated.

[0011] 2. The two discs are separated in an eight-shaped pattern from the front lower to the back upper. When used, the soil is separated better, further improving the sowing effect.

[0012] 3. The outer sides of the two discs are respectively provided with outer scrapers to scrape the mud adhered to the outer sides of the discs.

[0013] 4. An inner scraper is provided between the two discs to scrape off the mud adhered to the inner side of the discs. BRIEF DESCRIPTION OF THE DRAWINGS
