Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
This application provides a kind of rotary tillage soil-working aspiration small-sized seed precision drilling Unit erriger and methods, are suitble in radix rehmanniae preparata
It sows, first with the blade cut of rotary cultivator attachment rotation, smashes, loose, smooth soil, then after with ploughing shallowly being rectified
Precise sowing is carried out using seeding apparatus, is conducive to strive for farming season, improves effect and dilatory engine efficiency can be made full use of.
The Unit erriger is connected on tractor by three-link hitch, controls complete machine lifting by hydraulic device, should
Unit erriger is mainly by rotary tillage rack, speed change gear, hack site preparation device, housing, sowing rack, blower, sowing transmission gear shift
The compositions such as device, Pneumatic seeder, trench digging suppression device.
The course of work: providing power by tractor motive power output shaft, power is divided into two parts through gearbox, a part is used
In driving rotary cultivator work, a part driving aspiration precision drill blower high speed rotational operation, rotary knife axis is through gear shift
After drive, the Rotary tillage blade that bull helical uniformly configures, the direction of rotation of cutter shaft and tractor wheels are installed on rotary knife axis
Rotation direction is consistent, cuts soil layer from the front to the back, and soil block is thrown on housing and planker rearwardly and upwardly, is allowed to further break
It is broken, it is broken loosing soil, smooth, it is conducive to sowing, small-sized seed aspiration precision drill is also with three-link hitch
It is mounted in the rack of rotary cultivator, the power come through gearbox transmission is connected through Hooks coupling universal coupling with blower, blower rotation, shape
At negative pressure, seed is adsorbed on discharge plate by precision seeder, when reaching certain position, air pressure disappears, and seed is automatic
Discharging tube is fallen into, to be seeded into field, the rotation of pneumatic seeder seed tray provides power by traveling wheel, and becomes through sprocket wheel
Speed variator carries out speed change adjustment sowing spacing, and seed after planting is suppressed through suppressing device.
As shown in figures 1-8, it is the specific embodiment structure of the application:
1, transmission system: tractor 1 provides power, power is passed to transfer bevel gear box 16 through shaft coupling 2, transfer bores tooth
Power is divided into two parts by roller box 16, and a part passes to the gearbox 17 of 3 side of rotary tillage soil-working rack, after secondary speed change, band
Dynamic 18 high speed of rotary knife axis chooses to install, and rotary tillage cutterhead 6 and Rotary tillage blade 5 are equipped on rotary knife axis, cuts soil layer from the front to the back, and
Soil block is thrown rearwardly and upwardly on housing 7, is allowed to further be crushed, it is broken loosing soil, smooth, it is conducive to sowing；It is another
Partial power passes on big belt pulley 20 through second shaft coupling 19, power is reached small belt pulley 21 through belt, to drive wind
11 high-speed rotation of machine forms negative pressure and is adsorbed seed in seed tray 13 in feed mechanism for seed by seeding tracheae 22, when reaching one
When positioning is set, air pressure disappears, and seed automatically falls into discharging tube, to be seeded into field；The power that discharge plate rotates in feed mechanism for seed
From traveling wheel 24, the rotation of traveling wheel 24 drives co-axial walking drive sprocket 27 to operate, through chain by power transmission
To walking driven sprocket 29, six square shafts 37 will be driven to rotate after 23 speed change of sprocket gear shifting box, be mounted on broadcasting on six square shafts 37
Kind drive sprocket 33 will drive sowing intermediate chain wheel 34, sows sprocket wheel 36 to rotate, so that seed tray is driven to rotate, sowing tensioning chain
Wheel 35 and walking expansion tightening wheel 28 are tightener sprocket, play adjustment effect to transmission.
2, copying device: when work, the work of 1 hydraulic device of tractor will be joined by the three-point hitch of rotary tillage rack
It closes unit to put down, the cutterhead of rotation cuts soil layer；The flexible of hydraulic cylinder 8 can be such that seeder frame rotates around point of rotation O, from
And the lifting of aspiration precision drill is adjusted, aspiration precision drill seed level is carried out；The ABCD of aspiration precision drill is constituted
Parallelogram seed level adjust device, seeding apparatus and trench digging suppression device can used parallelogram arrangement be parallel to BC or more
It floats, to play seeding apparatus profiling and control the function of seed level；Rotating handle 38 can be adjusted holddown spring 39, from
And ditching depth is adjusted, to be adjusted to trench digging positive pressure devices.Profiling is applied in combination with four-bar mechanism, guarantees seeder
Depth of planting is consistent in sub- seeding process, and miniature press wheel directly presses kind, takes care of yourself seed and comes into full contact with soil, absorbs moisture
It is not in earth's surface leakage kind phenomenon with nutrient.
3, speed changing function: the adjustment of rotary tillage soil-working aspiration small-sized seed precision drilling Unit erriger sowing spacing passes through sprocket wheel
The various combination of 23 inner sprocket of gearbox realizes different revolving speeds, and the rotation of traveling wheel 24 drives coaxial walking drive sprocket 27
One piece of rotation rotates by chain-driving walking driven sprocket 29, so that coaxial sprocket wheel a40, sprocket wheel b41 be driven to rotate, leads to
The position for crossing adjustment sprocket wheel can be combined with sprocket wheel 42-47 to work, and forms 12 kinds of speed changes.
Adjustment process are as follows: first remove claw 52 upwards, tensioning apparatus will be rotated along P axis, and chain 53 is loosened, will
Sprocket wheel 40,41 is transferred to position appropriate, combines with the sprocket wheel in sprocket wheel 42-47, then by 52 clamping of claw, plays tension.
4, a tractor serves several purposes: rotary tillage soil-working aspiration small-sized seed precision drilling Unit erriger can be by Unit erriger from seeder three
It dismantles, can be acted on dedicated for rotary tillage at point suspension, it can also be used to which aspiration precise sowing realizes a tractor serves several purposes.
5, new process program: rotary tillage soil-working aspiration small-sized seed precision drilling Unit erriger realizes radix rehmanniae preparata farming, broken
The process program directly cultivated after native, smooth.
6, sowing line-spacing adjustment: the adjustment that rotary tillage soil-working aspiration small-sized seed precision drilling combination machine aspiration sows line-spacing can
It is adjusted by adjusting seeding apparatus in the position of seeder frame 26.
Seeding process is blower rotation, so that aspiration precise seeder left upper portion is formed negative pressuren zone, seed 51 is adsorbed on
On seeds sucker 48.Sows sprocket wheel 36 rotates, and drives seeds sucker 48 to rotate, adsorbs seed on it also together with rotation.And
It is communicated in aspiration precise seeder left lower with atmosphere, negative pressure disappears, and seed falls from seeds sucker 48, falls into along delivery pipe
In kind ditch.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
