Abstract

An adjustable covering shovel connected out a disc is provided, which pertains to the agricultural machinery. Wherein, at rear sides of the following beams of the pulling frames at left and right side, installing stand plates are mounted symmetrically; a disc shaft is mounted on the central position at outside of the arc convex of the disc assembly, a disc with a disc screw is fixedly nested on the disc shaft; a connection shaft is fixedly mounted on the outer surface of a disc-positioning sleeve in right angle to the axial line of the disc-positioning sleeve; a connection sleeve with a connection-shaft screw is looped on the connection shaft; a disc stand is fixed with the connection sleeve, and the disc stand is mounted on the stand plates, so as to mount the disc assembly as a whole on the following beams of the pulling frames. The utility model enlarges the inside space of the earth-covering disc, will not drag earth at operation, nor twist grass and straws, is featured by complete functions, easy adjustment, good operation quality, high efficiency and less fault, etc.

Description

The adjustable covering device of the outer connection of disk

Technical field

The utility model belongs to agricultural machinery, relates generally to earthing assembly on the plow-plant equipment.

Background technology

At present, the disk covering device that is made of a pair of disk coverer relative tilt configuration assembling is the earthing operating assembly of using always on the plow-plant equipment in the real agricultural production, for mechanized agricultural operation has been made positive contribution.But, because it is middle inboard that the clamping parts on such disk covering device all are configured in the relative arc-shaped concave of pair of discs, when with after this disk coverer assembly clamping is to the plow-plant equipment, its two disks inner space is very narrow and small, plough when broadcasting operation, the disk coverer assembly very easily takes place drag operation faults such as soil, extension grass, extension straw, not only influence the earthing operation effectiveness, when dragging soil serious, even can scrape kind of a bed to the kind grain of broadcasting in kind of bed, cause inclined to one side kind, leak and plant, reduced the seeding operation quality significantly.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, and design provides the outer connection of a kind of disk adjustable covering device, reaches to guarantee the earthing operation quality, reduce and avoid the operation fault to take place, improve and plough the purpose of broadcasting operating efficiency.

Basic design of the present utility model is symmetrical installation seat plate on upper lateral part behind the suitable beam of trying to stop people from fighting each other of left and right side; Disc shaft is fitted on the center, disc assembly arc convex outside portion, and the disk fixed cover of equipped disk jackscrew is sleeved on the disc shaft; Connecting axle becomes vertical angle to be packed on the disk positioning sleeve outer surface with disk positioning sleeve axle center line, the adapter sleeve that the connecting axle jackscrew is installed is sleeved on the connecting axle, disk support and adapter sleeve are loaded into one, disk support is installed on the seat board, disc assembly integral body is fitted in the Shun Liangshang that tries to stop people from fighting each other, so far constitutes the adjustable covering device of the outer connection of disk.

The utility model is fitted in the disk coverer clamping parts of new structure on a pair of disk coverer arc convex outside portion, enlarged the disk coverer inner space, do not drag soil during operation, do not hang grass, do not hang straw, have rational in infrastructure, function is complete, easy to adjust, earthing is effective, use is reliable, fault is few characteristics.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The adjustable covering device of the outer connection of disk comprises the girder 1 of trying to stop people from fighting each other, tries to stop people from fighting each other along beam 11, try to stop people from fighting each other crossbeam 12 and disc assembly 5, symmetrical installation seat plate 2 on the suitable beam 11 back upper lateral parts of trying to stop people from fighting each other of left and right side; Disc shaft 7 is fitted on the center, disc assembly 5 arc convex outside portion, and the disk fixed cover 6 of equipped disk jackscrew 4 is sleeved on the disc shaft 7; Connecting axle 9 becomes vertical angle to be packed on disk positioning sleeve 6 outer surfaces with disk positioning sleeve 6 axial lines, the adapter sleeve 8 that connecting axle jackscrew 10 is installed is sleeved on the connecting axle 9, disk support 3 is loaded into one with adapter sleeve 8, disk support 3 is installed on the seat board 2, disc assembly 5 integral body is fitted in tries to stop people from fighting each other along on the beam 11.On disk support 3 upper ends, be provided with slotted hole 13.

Operation is used when adjusting, and unclamps disk jackscrew 4, and disc shaft 7 is moved in disk fixed cover 6, realizes the adjusting of disc assembly 5 relative distances; Unclamp connecting axle jackscrew 10, connecting axle 9 is rotated in adapter sleeve 8, finish disc assembly 5 angle of inclination adjustment; Utilize the slotted hole 13 on disk support 3 upper ends to realize disc assembly 5 with respect to the front and back position variation adjusting of trying to stop people from fighting each other along beam 11.After disc assembly 5 being pulled down from the seat board 2, utilizing the crossbeam 12 of trying to stop people from fighting each other the scraper-type covering device can be installed in and trying to stop people from fighting each other becomes scraper-type covering device facility along on the fine strain of millet 11, has enlarged the facility scope of application, dual-use, and applicability is strong.
