Abstract

The utility model discloses a blade shaft of rice and wheat straw chopper. The chopper comprises a blade shaft (1) arranged in a shell body, the blade shaft (1) is provided with moving blades (3). Theblade shaft of rice and wheat straw chopper is characterized in that: the blade shaft (1) is provided with a plurality of moving blade units; the moving blade unit comprises a group of concave bladeblocks (2) and a group of moving blades (3). The group of concave blade blocks (2) is welded at the blade shaft (1) at the same direction, the concave blade blocks (2) are provided with the moving blades (3). The blade shaft provided by the utility model has reasonable structure, and increases power of straw-shredding, the rotating blade shaft drives the concave blade blocks to form whirlwind, therefore, the travel and evenness of dispersion are increased.

Description

The cutter shaft of rice and wheat straw cutter mill

Technical field

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

Background technology

In order to protect environment and soil property, at present, forbid that the peasant burns rice and wheat straw in the field, are also fields of crushing straw and rationally utilize best means, it is short that existing stalk cutter crushed stalk is shed stroke, shed inhomogeneous, the fault rate height, use cost is big.

Summary of the invention

The purpose of this utility model is: a kind of cutter shaft of rice and wheat straw cutter mill is provided, and this cutter shaft structure is reasonable, improves the stalks cutting effect, increases and sheds stroke, prolongs blade service life.

Technical solution of the present invention is: cutter mill comprises the cutter shaft of installing in the housing, moving knife is installed on the cutter shaft, it is characterized in that: some movable cutter set are installed on the cutter shaft, movable cutter set is made up of one group of spill tool rest and one group of 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.

In the cutter shaft of rice and wheat straw cutter mill of the present utility model, moving knife is trapezoidal cutter, establishes double-sided blade on the moving knife.

During operation, the cutter shaft rotation, the spill tool rest forms whirlwind with the cutter shaft rotation, and stalk chopped is shed by long-range.

The utlity model has following advantage: 1, the spill tool rest on the cutter shaft forms whirlwind when rotated, and whirlwind helps shedding of stalk, and not only stroke is far away but also shed evenly; 2, the moving knife of double-sided blade can use on the two sides, does not change original dynamic balancing, easy accessibility, and long service life reduces use cost.
