Abstract

The utility model relates to a one-cavity three-chamber seeding device, which belongs to the agricultural machinery. A long strip hole is arranged on the upper end surface of a casing body, a tightening element group is inserted and assembled in a hair brush elastic seed blocking plate hole and the long strip hole, the hair brush elastic seed blocking plate is installed in the casing body, the lower end part of the hair brush elastic seed blocking plate is contacted and matched with a hair brush wheel, and the outer diameter size of an indent seeding wheel is 130 to 140 mm; the structure of the seeding device is simple, the effect of the hair brush seed blocking is good, the service life of parts and components is long, the maintenance cost is low, the regulation is convenient, and the seeding device is suitable for the demand of the high-speed sowing operation.

Description

One chamber, three Room seeding units

Technical field

The utility model belongs to agricultural machinery, relates generally to the seeding operating assembly on the seeding machinary.

Background technology

At present, the seed retaining plate that matches with brush-wheel of configuration all is uncontrollable being fixedly mounted on the seeder unit shell in the three Room seeding units of one chamber, after the long working, the brush-wheel wearing and tearing, its diameter diminishes, between seed retaining plate bottom and brush-wheel outer surface cooperation position, produce big gap, retaining kind of operation effectiveness reduces, and brush-wheel surface adhesion kind grain increases, and it is bad that seeding quality becomes, renewal part has increased maintenance and operating cost, and facility are short service life.In addition, now use nest eye seed wheel outside diameter size all below 130 millimeters, incompatibility high speed seeding operation needs.

Summary of the invention

The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, design provides an a kind of chamber three Room seeding units of new construction, reaches to guarantee hairbrush catch kind operation quality, elongated component service life, reduce the operation maintenance cost, satisfy the purpose that adapts to high speed seeding operation needs.

Basic design of the present utility model is, on the housing upper surface, have strip hole, the inserting of securing member group hairbrush elasticity seed retaining plate adjustable ground is installed on the housing, and hairbrush elasticity seed retaining plate bottom contacts cooperation with brush-wheel in hairbrush elasticity seed retaining plate hole and in the strip hole.Nest eye seed wheel outside dimension Φ is the 130-140 millimeter, so far constitutes a chamber three Room seeding units.

The utility model is simple in structure, and the hairbrush retaining is planted effective, the parts long service life, and maintenance cost is low, regulates simple and convenient, is fit to high speed seeding operation needs.

Description of drawings

Fig. 1 is a chamber three Room seeding unit general structure schematic diagrames;

Fig. 2 be among Fig. 1 A to partial view.

Piece number explanation among the figure:

1, securing member group, 2, hairbrush elasticity seed retaining plate, 3, loam cake, 4, housing, 5, nest eye seed wheel, 6, Seed-cleaning tool, 7, elasticity are protected kind of an assembly, 8, brush-wheel, 9, sowing adjusting cover plate, 10, strip hole.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.An a kind of chamber three Room seeding units comprise housing 4 and are fitted in loam cake 3, nest eye seed wheel 5, Seed-cleaning tool 6, elasticity on the housing 4 and protect kind of assembly 7, brush-wheel 8, sowing and regulate cover plate 9, on housing 4 upper surfaces, have strip hole 10,1 inserting of securing member group is in hairbrush elasticity seed retaining plate 2 holes and in the strip hole 10, hairbrush elasticity seed retaining plate 2 adjustable grounds are installed on the housing 4, and hairbrush elasticity seed retaining plate 2 bottoms contact cooperation with brush-wheel 8.Nest eye seed wheel 5 outside dimension Φ are the 130-140 millimeter.

When brush-wheel 8 generation wearing and tearing outside diameters diminish, loosening fasteners group 1 with hairbrush elasticity seed retaining plate 2 along the strip hole on the housing 4 10 to brush-wheel 8 side shiftings, adjust and to cooperate distance to correct position between brush-wheel 8 outsides and hairbrush elasticity seed retaining plate 2 bottoms, utilize securing member group 1 that hairbrush elasticity seed retaining plate 2 is fastened on strip hole 10 interior getting final product again.The nest eye seed wheel 5 that increases circumferential size can satisfy high speed seeding operation needs, improves operating efficiency, guarantees operation quality.

Claims

1. chamber three Room seeding units, the loam cake (3), nest eye seed wheel (5), Seed-cleaning tool (6), the elasticity that comprise housing (4) and be fitted on the housing (4) are protected kind of an assembly (7), brush-wheel (8), sowing adjusting cover plate (9), it is characterized in that on housing (4) upper surface, having strip hole (10), securing member group (1) inserting is in hairbrush elasticity seed retaining plate (2) hole and in the strip hole (10), hairbrush elasticity seed retaining plate (2) is installed on the housing (4), and hairbrush elasticity seed retaining plate (2) bottom contacts cooperation with brush-wheel (8).

2. a chamber according to claim 1 three Room seeding units is characterized in that nest eye seed wheel (5) outside dimension Φ is the 130-140 millimeter.
