Description

The rice and wheat straw cutter mill

Technical field

The utility model relates to cutter mill, is specifically related to the rice and wheat straw cutter mill.

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; it is low that existing stalk cutter is shed power; 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 purpose of this utility model is: a kind of rice and wheat straw cutter mill is provided, and 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 utility model is: this cutter mill connects transmission mechanism by main frame and forms, it is characterized in that: main frame comprises case, cutter shaft, moving knife and stationary knife, the upper shell lower house that is connected through the hinge forms case, in lower house, cutter shaft is installed by bearing, some movable cutter set are installed on the cutter shaft, movable cutter set is made of a row moving knife and spill tool rest, the spill tool rest is the direction uniformity and is welded on the cutter shaft, moving knife is installed on the spill tool rest, at the inwall of lower house stationary knife is installed and is cooperated moving knife.

In the rice and wheat straw cutter mill of the present utility model, one group of stationary knife buck plate of adjustable installing on the lower house inwall is installed some stationary knifes on the stationary knife buck plate.

In the rice and wheat straw cutter mill of the present utility model, removable time careless grass guard is installed on the upper enclosure inner wall.

In the rice and wheat straw cutter mill of the present utility model, the discharging opening of lower house is installed the deflector of one group of extended type adjustable angle formula.

In the rice and wheat straw cutter mill of the present utility model, cutter shaft is reinforced cutter shaft.

In the rice and wheat straw cutter mill of the present utility model, moving knife is a thickening type, and two-sided cutting edge is arranged on it.

During installation, upper shell is installed in and is positioned at grain header grass outlet rear on the grain header frame, and passive belt wheel is installed on the cutter shaft, on the grain header drum shaft driving pulley is installed, the V-belt of mounting strap regulating wheel on main, the passive belt wheel; During use, the stalk that comes out from the grain header grass outlet enters lower house by the Cao Kou that advances of upper shell, is shredded under the cooperation of moving, stationary knife, and stalk chopped is shed the field through deflector under the whirlwind that cutter shaft rotation and spill tool rest form; If during the field piece operation that runs into that stalk need not to shred, lower house started from the hinge hinged place hang on the grain header, thereby realize not cutting stalk.

The utlity model has following advantage: 1, reinforced cutter shaft, can not rupture during the high strength operation, tear, drawing crack, intensity is 2 times 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 on the moving knife, 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, optional ceramic coating blade improves 1 times service life; 5, adjustable stationary knife buck plate can be regulated the relative position relation of moving knife and stationary knife, so that shred stalk better; 6, extended type adjustable angle formula deflector, the water conservancy diversion angle is big, distance, throwing are loose evenly; 7, hang hinge fast, other purposes is arranged and need not to shred, can be apace lower house be suspended on the rear of silo from the upset of hinge hinged place, will lower house do not pull down and lose time from upper shell if run into harvesting field piece stalk; 8, removable time careless grass guard, when normally shredding operation, to return careless grass guard installs and the upper shell upright position, if run into the field piece that need not to shred, to return four bolts of careless grass guard when hanging up lower house pulls down, can pull down back careless grass guard, make things convenient for Lysimachia sikokiana, avoid the generation of stifled careless phenomenon.
