Abstract

The utility model discloses a novel seeding machine, which belongs to a seeding part in a farming machine; a bearing room is arranged on one side wall of the shell body in the machine; a connecting hole is arranged on the position corresponding to the side wall, which is matched with the outer diameter size of the seeding roller. A roller axis provided with the seeding roller and the tightening part is arranged on the bearing room through a bearing; the seeding roller is shaped as a cantilever situation in whole and is arranged inside a shell body cavity. The utility model is with simple structure; the utility model is characterized in that the utility model is convenient to dismount and exchange the seeding roller; the utility model is easy to be maintained with reliable operation, low cost and much better generality.

Description

New-type seeding unit

Technical field

The utility model belongs to cultivates sowing assembly supporting on the facility in the agricultural machinery.

Background technology

Mechanical seeding unit is that various countries, the world today use comparatively general crop seeding device, and it is more extensive that China uses, and is core workpiece in the mechanization seeding operation.Current, various mechanical type seeding units are that the dry farmland seeder toolization has been made positive contribution.But, because 2 supporting structures are all adopted in the housing of existing mechanical type seeding unit and the assembling of seed shaft, equipped seeding roller or seed plate between two supporting-points, therefore in maintenance or very numerous and diverse when changing kind of dish (roller), seed shaft need be dismantled from housing and bearing down and be ressembled again and can finish, reduced operating efficiency, made troubles to the user.

Summary of the invention

The purpose of this utility model is exactly the inconvenience when changing seed plate (roller) or maintenance at existing mechanical seeding unit, design provides a kind of new-type seeding unit, by on a sidewall of housing, bearing chamber being set, and on the roll shaft of cantilever structure, install the structure of seeding roller, reach and simplify the seeding unit structure, be convenient to the purpose that the seeding roller is changed, for ease of maintenaince maintained, increases work efficiency.

Basic design of the present utility model is, is provided with bearing chamber on a sidewall of housing, is provided with a through hole that is complementary with seeding roller outside dimension on the housing wall of a relative side with bearing chamber; On bearing chamber, utilize bearing configuration that roll shaft is installed, be positioned at suit seeding roller on the housing chamber cantilever roll shaft partly, seeding roller integral body is in the housing chamber, and securing member is fastened on the seeding roller on the roll shaft, and the seeding roller cooperates with seeds protecting plate on the housing.

The utlity model has simple in structure, cheap, disassembling, assembling and replacing seeding roller convenient, for ease of maintenaince with maintenance, transaction capabilities is reliable, versatility is wide characteristics.

Piece number explanation among the figure:

1, bearing, 2, roll shaft, 3, seeding roller, 4, housing, 5, securing member, 6, clear brush, 7, seeds protecting plate, 8, bearing chamber, 9, the through hole of planting.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.New-type seeding unit comprises housing 4, the clear brush 6 of planting, and is provided with bearing chamber 8 on a sidewall of housing 4, with the housing wall of bearing chamber 8 relative sides on be provided with a through hole 9 that is complementary with seeding roller 3 outside dimensions.On bearing chamber 8, utilize bearing 1 configuration that roll shaft 2 is installed, be positioned at suit seeding roller 3 on the housing 4 chamber cantilevers roll shaft 2 partly, seeding roller 3 integral body are in housing 4 chambeies, securing member 5 is fastened on seeding roller 3 on the roll shaft 2, and seeding roller 3 cooperates with seeds protecting plate 7 on the housing 4.

When changing seeding roller 3 or maintenance, screw off securing member 5, seeding roller 3 is unloaded, takes out with through hole 9 from roll shaft 2, the seeding roller that needs to change is installed is from here again got final product.

Claims

1, a kind of new-type seeding unit, comprise housing (4), the clear brush (6) of planting, it is characterized in that on a sidewall of housing (4), being provided with bearing chamber (8), with the housing wall of the relative side of bearing chamber (8) on be provided with a through hole (9) that is complementary with seeding roller (3) outside dimension.

2, new-type seeding unit according to claim 1, it is characterized in that on bearing chamber (8), utilize bearing (1) configuration that roll shaft (2) is installed, be positioned at upward suit seeding roller (3) of housing (4) chamber cantilever roll shaft (2) partly, seeding roller (3) integral body is in housing (4) chamber, securing member (5) is fastened on seeding roller (3) on the roll shaft (2), and seeding roller (3) cooperates with seeds protecting plate (7) on the housing (4).
