Description

With the supporting rice and wheat straw cutter mill of longitudinal axis stream roller grain header

Technical field

The present invention relates to cutter mill, be specifically related to and the supporting rice and wheat straw cutter mill of longitudinal axis stream roller grain header.

Background technology

At present; in order to protect environment; rice and wheat straw does not allow to burn in the field, and burning can have influence on soil property, advocates straw-returning for this reason; existing stalk cutter chopping weak effect; it is short to shed stroke, sheds inhomogeneously, and the cutter mill that has is shed the uniformity in order to improve; in cutter mill, increase fan blower, thereby increased the manufacturing cost and the use cost of cutter mill.

Summary of the invention

The objective of the invention is to: provide a kind of and the supporting rice and wheat straw cutter mill of longitudinal axis stream roller grain header, this cutter mill is simple in structure, and is with low cost, easy to use, sheds evenly, sheds distance, sheds effective.

Technical solution of the present invention is: this cutter mill connects transmission mechanism by main frame and forms, cutter mill comprises housing, cutter shaft, moving knife and stationary knife, through bearing cutter shaft is installed in the housing, moving knife is installed on the cutter shaft, the inwall that stationary knife is installed in housing cooperates moving knife, a wherein end of cutter shaft is installed duplicate sprocket, duplicate sprocket connects the drive sprocket of the uni-drive gear box of grain header through double strand chain, it is characterized in that: some movable cutter set are installed on the cutter shaft, movable cutter set is made up of spill tool rest and moving knife, one group of spill tool rest is the direction uniformity and is welded on the cutter shaft, on the spill tool rest moving knife is installed.

Wherein, through self-locking nut, pad, bolt and fixed head moving knife is installed on the spill tool rest.

Wherein, moving knife is trapezoidal cutter, establishes double-sided blade on the moving knife.

Wherein, by bolt connection support, housing ties by bolt and U type through mounting bracket and is connected on the grain header bottom girder frame on the housing.

Wherein, at the anterior stationary knife adjustable plate of installing of the inwall of housing, two row U type stationary knifes are installed on the stationary knife adjustable plate are cooperated moving knife.

Wherein, cutter shaft is reinforced cutter shaft.

Wherein, the regulating wheel support is installed, on the regulating wheel support regulating wheel is installed, regulating wheel tensioning double strand chain on the right side of housing.

Wherein, at the rear portion of mounting bracket crash bar is installed.

During installation, the main frame of cutter mill is installed through mounting bracket on the grain header bottom girder, cutter mill is positioned at grain header grass outlet rear and front and back up-down adjustment, and the uni-drive gear box of transmission of power and conversion power direction is installed on the grain header; During use, the stalk that comes out from the grain header grass outlet enters in the housing by the Cao Kou that advances of housing, is shredded under the cooperation of moving, stationary knife, and stalk chopped is shed the field under the whirlwind that grain header air blast, cutter shaft rotation and spill tool rest form.

The present invention has the following advantages: 1, reinforced cutter shaft, and can not rupture during the high strength operation, tear, drawing crack, intensity is the twice of common cutter shaft; 2, spill tool rest, the intensity height, up rightness is good, indeformable, good stability, can not come off, tear from cutter shaft, and the spill tool rest that the direction uniformity is installed can form whirlwind, makes things convenient for shedding of stalk; 3, the two-sided cutting edge of thickening type, stressed back is indeformable, non-warping, can be because of distortion and stationary knife collision, but the anti-turnback in original place continues to use behind a surface wear, does not influence the former dynamic balancing of machine; 4, the stationary knife adjustable plate is regulated the relative position relation of moving knife and stationary knife, and selects stationary knife that quantity is installed, so that shred stalk better; 5, movable arbor cutter quantity is optional, covers 34,38 or 42, makes to be made up better between chopping length and chopping required drive.
