Abstract
The utility model provides a straw is smashed and is gone back field with combination blade includes the rubbing crusher arbor, the tool magazine, the bolt fastening round pin, the tulwar, straight sword, characterized by should make up the middle straight sword overlapping built -up connection of sheet -like always that adds of tulwar that the blade adopted two sheet -likes, adorn on the tool magazine of epaxial two splint shape of rubbing crusher sword through bolt fastening round pin cluster, compress tightly blade and arbor fixed, the tulwar blade is by the tulwar blade body, the tulwar mounting hole, tulwar line land oral region and tulwar high frequency quench to distinguish and constitute, 150 contained angles are bent into from bottom 50mm to the tulwar, straight sword blade is by the straight sword blade body, straight sword mounting hole, straight knife mark land oral region quenches frequently to distinguish with straight knife height and constitutes, the utility model discloses strong adaptability, the blade is sharp, wear resistance is good, shear the reinforce, can effectively smash multiple crop straw such as maize, wheat, rice, peanut, and the operating efficiency is high, and the straw is smashed effectually.
Description
Technical field
The utility model relates to and is a kind ofly arranged on the composite blade that straw crushing and field-returning machine uses, and particularly a kind of straw chopping and returning composite blade, belongs to agricultural machinery technological field.
Background technology
In recent years every busy farming season, a large amount of agricultural crop straws goes out of use burning, cause the wasting of resources, slaking soil, pollute environment, people's lives and traffic safety are had a strong impact on, be unfavorable for the sustainable development of agricultural, mainly stalk of tracing it to its cause can not be used effectively, and utilize stalk the most effective the most direct mode to be exactly straw-returning, straw cutting apparatus crushing maizes in the market etc. are crisp, hard stalk effect is better, and pulverize wheat, the soft stalk such as paddy rice effect is poor, this is mainly because its crushing knife tool used is by structure, form limit, to wheat, the soft stalk such as paddy rice can not effectively be pulverized.
Summary of the invention
To go out of use burning to solve a large amount of agricultural crop straws, cause the wasting of resources, slaking soil, pollute environment, people's lives and traffic safety are had a strong impact on, be unfavorable for the problem of the sustainable development of agricultural, overcome straw cutting apparatus in the market to the defect of soft crushed stalk weak effect, the utility model provides one and is arranged on straw crushing and field-returning machine and uses, can a kind of straw chopping and returning composite blade of the multiple kinds of crops such as crushing maize, wheat, paddy rice, peanut.
The technical scheme in the invention for solving the technical problem is: a kind of straw chopping and returning composite blade comprises cracker cutter shaft, tool magazine, bolt steady pin, tulwar, straight knife, the straight knife overlapping combinations adding a straight plate shape in the middle of the tulwar of two sheet shapes is adopted to connect, be bolted on the tool magazine of pin two clamping plate shapes on cracker cutter shaft in tandem, blade and cutter shaft are fixed, tulwar blade is by tulwar cutter blade, tulwar installing hole, tulwar line land mouth region and tulwar high-frequency quenching district composition, tulwar is bent into 150 ° of angles from bottom 50mm, straight knife blade is by straight knife cutter blade, straight knife installing hole, straight knife line land mouth region and straight knife high-frequency quenching district composition, these two kinds of its materials of blade are 65Mn, two-sided with line tooth, the wide 7mm in Wen Chi district, adopt the wide 15mm in high-frequency quenching district, HRC44-48, the blade cross section two ends of straight knife and tulwar are all in double-edged sword cross sectional shape, when cracker cutter shaft High Rotation Speed, drive composite blade to make high speed centrifugation to rotate, the ledger-plate be arranged on straw crushing and field-returning machine crushing chamber coordinates composite blade to carry out straw chopping and returning operation again.
The beneficial effects of the utility model are: strong adaptability, can the effective multiple kinds of crops stalk such as crushing maize, wheat, paddy rice, peanut, and operating efficiency is high; Cutting edge is sharp, anti-wear performance good, shearing force is strong, and crushed stalk is effective.
