Abstract
The utility model provides a forage chopping cylinder which comprises an annular column body with a central rotation shaft, cutter rests and cutter blades. The cutter rests are evenly distributed on the outer surface of the annular column body, and at least one cutter blade is arranged on each cutter rest. Each cutter blade comprises a first cutter blade unit and a second cutter blade unit. The edge of each first cutter blade unit is parallel to the central line of the rotation shaft, the edge of each second cutter blade unit is oblique to the central line of the rotation shaft, and switching of shearing modes can be achieved through replacement of different cutter blades. The forage chopping cylinder has the advantages of being simple in structure, convenient to install and maintain, and high in applicability.
Description
Technical field
The utility model relates to agricultural cutter, particularly a kind of chopping cylinder cutterhead of grain header.
Background technology
Automatic projecting grain header is mainly provided with a chopping cylinder, comprises the dismountable cutterhead of blade, mounting tool post successively on cutterhead, and knife rest is used for installing blade, can be by the crops chopping being involved in grain header.
On conventional cutterhead, make blade or have a certain degree installation parallel with rotating shaft by knife rest, when under the blade and the uneven situation of rotating shaft of blade, carry out material harvesting by blade and shearing bar, be similar to the shearing mechanism of scissors, this type of situation, can be also a kind of circular knife etc., belongs to one and pulls formula shearing into.
The shortcoming that the formula of pulling into is sheared is that direction and the rotation of shearing force is not parallel, shearing force is decomposed, in the time running into the little material of the moisture abundances such as green grass, coefficient of friction, material will lead and escape on one side, cause and shear not exclusively, in the situation that feed speed is constant, actual shearing length also will increase.
Although the formula of pulling into is sheared and is had certain defect, but most of crops stand good in this type of cut mode, thereby be widely used on some agricultural cutters, as the harvesting of the crops such as corn, for crops such as green grass, this type of grain header has some limitations, and it is also quite difficult to change cutterhead.
Summary of the invention
For solving the limitation existing in existing grain header, that the utility model provides is a kind of convertible shear mode, simple in structure, be convenient to the forage chopping cylinder of maintenance.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of forage chopping cylinder, comprise circle ring column, knife rest, the blade of center with rotating shaft, described knife rest is uniform is arranged on described circle ring column outer surface, a blade is at least installed on described knife rest, between the extend longitudinally line of described knife rest and shaft centerline, mutually tilts.
Described blade comprises the first blade and the second blade, described the first blade comprises the first installed surface and the first blade face, between described the first blade face and the first installed surface, mutually tilt, between described the first blade face and the first installed surface, be connected the stupefied parallel described shaft centerline of cutter of described the first blade face by transition face;
Described the second blade comprises the second installed surface and the second blade face, and described the second blade face is parallel with the second installed surface, between the stupefied and described shaft centerline of the cutter of described the second blade face, mutually tilts.
In the utility model, the shearing bar on described cutterhead and grain header is used in conjunction with, and the first blade is all installed on described knife rest, is cut-in type shear mode, the stupefied and described spindle central line parallel of the cutter of described blade; The second blade is all installed on described knife rest, for pulling formula shear mode into, between the stupefied and described shaft centerline of the cutter of described blade, is mutually tilted; Two kinds of blades are installed on described knife rest, are mixed mode.
The utility model compared with the existing technology has the following advantages and effect: described blade is arranged on circle ring column by knife rest, for convenience detach, change and safeguard.2, blade comprises the first blade and the second blade, can need to carry out the replacing of blade with difference, thereby changes shear mode, and adaptability is stronger.3, blade structure is simple, easy for installation, has improved the useful life of cutterhead.
