Abstract
The utility model discloses a straw-smashing device of a grain combine harvester. The straw-smashing device of the grain combine harvester comprises a smashing cutter shaft, a moving cutter combination arranged on the smashing cutter shaft and a fixed cutter combination fixed on a rack of the harvester, wherein the fixed cutter combination and the moving cutter combination smash straw in a matching mode, the smashing cutter shaft is horizontally supported on a mounting mouth position of a grain-threshing chamber of the harvester, and the fixed cutter combination and the moving cutter combination are arranged in a straw-discharging mouth of the gain-threshing chamber. Compared with the prior art, the straw-smashing device of the grain combine harvester has the advantages of being simple in structure, convenient to assemble and disassemble, and capable of smashing the straw discharged through the grain-threshing chamber efficiently. Beside, the fact that the straw is smashed and returned to field after crop is harvested and threshed by the combine harvester is guaranteed.
Description
Technical field
The utility model relates to farm machinery, and specifically, the utility model relates to a kind of grain combine straw millstone.
Background technology
When carrying out the grain harvest operation, the straw millstone of full feeding grain combine by arranging on it with direct returning to farmland after the straw crushing of threshing discharge, avoids straw burning to cause the situations such as fire and the dirty combustion of air, and the easy farming of straw after pulverizing, returning and fertilizing.Straw millstone on existing combine is fitted to each other the function that realizes straw crushing by moving knife, stationary knife, but complex structure, installing/dismounting is inconvenient, and because straw millstone is heavy, causes complete machine oscillation larger, and consumed power is large.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of grain combine straw crusher, it is simple in structure, assembly and disassembly is convenient, can be efficiently with the straw crushing of threshing chamber discharge, realize stalk crushing and returning after the threshing of combine harvesting crops.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of grain combine straw millstone, it comprises that the stationary knife of pulverizing cutter shaft, being located on the moving knife combination of pulverizing on cutter shaft and the frame that is fixed on grain header makes up, stationary knife combination and moving knife make up the crushing straw that matches, pulverize the cutter shaft cross-brace at the threshing chamber installing port place of grain header, moving knife combination and stationary knife combination are positioned at the inside of threshing chamber straw outlet.
The combination of described moving knife comprises axle sleeve, be fixed on a plurality of moving knife mounting discs on axle sleeve and be fixed on knife section in the moving knife mounting disc, axle sleeve by spline joint on described pulverizing cutter shaft.
Have centered by the axis of the described axle sleeve equally distributed number of line in described moving knife mounting disc and be the U-shaped installing port of two to eight, described knife section is arranged on this U-shaped installing port place.
The number of described moving knife mounting disc is two to eight.
Described stationary knife makes up to be divided into and lays respectively at two parts that described movable cutter set is closed the above and below.
Described pulverizing cutter shaft is driven by chain-drive mechanism or belt gear.
The utility model adopts technique scheme, compared with prior art, has advantages of simple in structurely, and assembly and disassembly is convenient, can be efficiently with the straw crushing of threshing chamber discharge, guaranteed the chopping and returning of straw after the threshing of combine harvesting crops.
