Abstract
The utility model relates to a wheat rice stalk breaker, in particular to a wheat rice stalk breaker fit with combine harvester, belonging to the technical field of harvester accessory tools, which comprises a shell with an inlet and an outlet, wherein a main shaft is transversely arranged in the shell; two ends of the main shaft are supported on the shell; one end of the main shaft penetrates through the shell, and the axle end is mounted with a driving chain wheel or a driving belt wheel; one side of the shell is provided with a tension wheel aligned with the driving chain wheel or the driving belt wheel, and the main shaft is mounted with a cutter. The wheat rice stalk breaker is characterized in that the cutter is fixedly connected with the main shaft. The utility model modifies the flail structure of prior wheat stalk breaker into fixed knife, to improve the cutting force of cutting edge and be suitable for harvesting wheat and rice, to break and return stalk to field.
Description
Technical field
The utility model relates to a kind of wheat rice straw cracker, and the particularly a kind of and matching used wheat rice straw of combined harvester cracker belongs to grain header outfitting tool technical field.
Background technology
Fast development along with agricultural mechanization, the domestic basic realization of agricultural product results mechanization, the results of wheat particularly, realize combining fully, wheat stalk is pulverized by the straw cracker that is assemblied on the reaping machine, shed uniformly in the farmland, the soil moisture conservation of realization farmland, getting fat, avoid the crop straw burning phenomenon, help environmental protection, but in the results of paddy rice, also do not have suitable crushed stalk equipment and rice harvesting machinery supporting at present, realize straw-returning, being badly in need of a kind of wheat stalk that both can carry out on the market pulverizes, being applicable to simultaneously the agricultural machinery product that rice straw is pulverized again, is articulated structure between the cutting knife of existing straw cracker and the main shaft, promptly so-called flail knife structure, rely on the pulverizing of the inertia realization of blade fully to stalk, crush force is less than normal, and the tenacity of fibre of paddy rice is stronger, and existing straw cracker is not good to the crushing effect of rice straw.
The utility model content
The utility model technical issues that need to address provide a kind of wheat rice straw cracker, by the architecture advances to existing straw cracker, make it both be applicable to the straw pulverizing, can satisfy the requirement that rice straw is pulverized simultaneously again.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
Wheat rice straw cracker, comprise in its structure: the casing that comprises import and outlet, horizontally set main shaft in the casing, the main shaft two end supports is on casing, main shaft one end runs through casing, axle head is installed drive sprocket or drive pulley, casing one side is alignd with drive sprocket or drive pulley regulating wheel is set, and cutting knife is installed on the main shaft, and cutting knife and main shaft are affixed.
Further improvement in the technical proposal of the present utility model is: weld Cutter apron on the main shaft, cutting knife is fixed on the Cutter apron.
Described built-in structure is realized by bolt or rivet.
Uniform 3-10 group blades of main-shaft axis direction, the sword face of every group of cutting knife is symmetrical arranged perpendicular to main-shaft axis and relative main-shaft axis.
Every group of cutting knife is made up of 2 or 4 cutting knifes.
The casing outlet vertically is provided with deflector.
Casing inner wall is provided with stationary knife.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The flail knife architecture advances that the utility model will have the wheat stalk cracker now is the dead knife structure, has increased the cut-out power of blade, can be applicable to wheat and rice harves simultaneously.
Weld Cutter apron on the main shaft, cutting knife is fixed on the Cutter apron, and this structure can be changed the excessive blade of wearing and tearing at any time.
Uniform 3-10 group blades of main-shaft axis direction, every group of cutting knife is made up of 2 or 4 cutting knifes, and the blade of varying number can be set according to varying in size of reaping machine, and casing inner wall is provided with stationary knife, can make crushed stalk more thorough
The sword face of every group of cutting knife is symmetrical arranged perpendicular to main-shaft axis and relative main-shaft axis, can guarantee the dynamic balancing of main shaft.
