Abstract
The utility model belongs to a machine for stubble plowing and farmland recovering comprising a body, a shift box, a rotary tillage roller, a crashing roller and a crashing garage. The utility model is characterized in that the axial direction of the crashing roller is well distributed with knife flywheels, the distance between two adjacent knife flywheels is 30-70 mm, and the knife flywheels are fixed with straight crashing knives and curve crashing knives by bolts. The knife flywheels correspond to the inner of the crashing garage are arranged with straight crashing knives, the right side and the left side of cutter heads of the crashing knives are equipped with wave-shaped cutting edges with high intensity, sound quality, a long service life and low cost, further the right edge and the left edge can be exchanged mutually. The crashing knives have the advantages of reasonable allocation, high straw crashing efficiency, good effect and low dynamic requirement. The gear wheels for driving are employed by the shift box, the rotary tillage roller and the crashing roller with high driving efficiency, which is capable of completely resolving the blocking caused by the straw squeezing, entwining in the process of the crashing and which is an ideal machine for stubble plowing and farmland recovering.
Description
Technical field
The utility model belongs to a kind of farm machinery, is a kind of straw crushing and field-returning machine with stalk and the direct chopping and returning of root straw stubble.
Background technology
The straw cutting apparatus kind of using is a lot of at present, but its structure is mostly identical, all is that cutter rolls, rotary blade rolls, frame constitutes by pulverizing, and at first with crushed stalk, rolls by rotary blade then stalk is imbedded in the soil.A kind of novel straw crushing and returning to field machine was disclosed on the Chinese patent gazette on September 24th, 2003, application number is 022702350, its structure is to roll, sting the pulverizing storehouse of rolling with under shed by body, gearbox, rotary tillage, this field-returning machine result of use is good, but also have following shortcoming and problem: (1) adopts the serrated knife thorn to roll pulverizing, low, the weak effect of crush efficiency, different in size, serrated knife rapid wear tooth, rust, usually cause the stalk extruding, be intertwined, not only power consumption is big, and the influence pulverizing is normally carried out; (2) thorn roll with rotary tillage roll with gearbox by belt transmission, easily skid, throw switch, can not guarantee to sting and roll the rotating speed that rolls with rotary tillage.
Summary of the invention
The purpose of this utility model provides a kind of straw crushing and field-returning machine, to solve low, the weak effect, different in size of prior art crush efficiency, serrated knife rapid wear tooth, rust, cause the stalk extruding, be intertwined, not only power consumption is big, and influence pulverizes normally to carry out easily skidding with belt transmission and throws switch, and can not guarantee to sting the rotating speed problem of rolling with rotary tillage of rolling.
The purpose of this utility model is achieved in that this field-returning machine is to be rolled, pulverized and roll and pulverize the storehouse and constitute by body, gearbox, rotary tillage, roll in pulverizing and to be evenly equipped with cutterhead vertically, two cutterhead spacings are 30～70mm, pulverizing rolls on face and is provided with circular arc pulverizing storehouse, and corresponding each cutterhead is provided with at least 2 the pulverizing cutter on its medial surface.
Pulverizing is rolled and rotary tillage roll with gearbox between adopt power transmission shaft and tooth to change transmission case to link to each other, lean on gear drive.
Pulverizing pulverizing cutter in the storehouse adopts straight knife two tops on straight knife itself and the cutterhead apart from being 3～30mm.
The intrinsic 1-12 group of bolt is pulverized cutter on the cutterhead, and every group has 2 straight knives, 2 tulwar, according to a left side is curved, straight, the right side is curved, straight systematic arrangement is fixed on the cutterhead both sides.
It is plate shaped that straight knife is, and its underpart handle of a knife is provided with bolt hole, and cutter head left and right side, top is equipped with the waveform blade.
Tulwar is bent plate shape, and its underpart handle of a knife is provided with bolt hole, and cutter head left and right side, top is equipped with the waveform blade, and cutter head bent angle a is 50～80 degree angles.
This utility model compared with prior art has the following advantages: (1) pulverize roll and rotary tillage roll with gearbox between by power transmission shaft be connected with gear, tooth commentaries on classics transmission, the transmission efficiency height does not throw switch, and can guarantee to pulverize to roll the rotating speed that rolls with rotary tillage; (2) pulverize cutter by being bolted on the cutterhead, pulverize cutter and change conveniently; (3) pulverize the cutter two sides and be equipped with the waveform blade, knife edge part is long, and not fragile, blunt left and right pulverizing cutter interchangeable, directly pulverize interchangeable of cutter; (4) cutterhead and pulverize the storehouse inboard straight to pulverize cutter rationally distributed, crushed stalk efficient height, effective, power requires low, can solve thoroughly that stalk easily pushes in the crushing process, twine, and often causes occlusive effects to pulverize the problem of normally carrying out.
