In one particular embodiment of the present invention, especially as shown in figure 4, the second stopper 922 is movably attached to sowing
Device second part 92,922 bottom of the second stopper are provided with rotation bolt 9221, are connected to seeder by rotating bolt 9221
Second part 92, the second stopper 922 with rotate 9221 axis trimming the second stopper 922 of bolt and the first stopper 921 it
Between angle, adjust Radix Polygalae seed sowing width.Second stopper 922 is set as fan-shaped annulus, the angle model of fan-shaped annulus
Enclosing is 60 ° to 180 °, and the angular range of fan-shaped annulus is preferably 60 °, by increasing the quantity of fan-shaped annulus, in seeds fall
Increase the whereabouts width of seed in approach as far as possible, 180 ° of angle sector annulus can also be used, increase Radix Polygalae seed
Whereabouts width range, the most commonly used is 90 ° of fan-shaped annulus, arrange in Radix Polygalae seeds fall approach, general second stopper 922
It is set as two layers of blocking, there are two 90 ° of the second stoppers 922 for first layer setting, and there are four the second stoppers for second layer setting
922, above-mentioned stopper is all spaced apart, and the width that can be realized Radix Polygalae seed increases, while increasing drop-off positions, is kept away
Exempt from Radix Polygalae seed only to embark on journey sowing, realizes and uniformly sowed on sowing width.Preferably, the first baffle of the first stopper 921
The extended line of 9211 upper surface length directions is by fan-shaped annulus midpoint, 9212 upper surface of second baffle of the first stopper 921
The extended line of length direction is by fan-shaped annulus midpoint.
During Radix Polygalae Special rotary broadcasts machine and plants Radix Polygalae seed, operated by practice:
Radix Polygalae is surface band small granule seed villous, and length, width and height are about are as follows: 3mm, 2mm, 1.6mm have at rectangular top
One small hoary hair, in production, foundation that the case where this small hoary hair bassets is adjusted as planting depth；
In the dedicated rotary sowing machine work of Radix Polygalae, the motion profile of Radix Polygalae seed are as follows: Radix Polygalae seed passes through rotation in plants case 7
Feed mechanism for seed 8 and gravity double action under fall into seeder first part 91, and make seeds fall speed under gravity
Be continuously increased, after the transition cambered surface between seeder first part 91 and seeder second part 92 with seeder second
The stopper that part 92 is arranged collides, to break up the fluidic structures formed during seeds fall, so that seed be made to pass through
The exit of seeder second part 92, which is uniformly dispersed, comes；
The characteristics of due to Radix Polygalae band villous, the attraction for keeping Radix Polygalae seed mutual is stronger, quickly turns to feed mechanism for seed 8
The raw frictional resistance of movable property is larger, influences the falling speed of seed, and reduces the amount of sowing, and design requirement is not achieved, and therefore, leads to
Crossing 8 amount of sowing of increase feed mechanism for seed can be only achieved production requirement.
As shown in figure 4, the first stopper 921 is fixed on the entry position that Radix Polygalae seed is entered by feed mechanism for seed 8, described second
The arc top midpoint of fan-shaped circular arc is arranged in the rotation bolt 9221 of stopper 922, and the elongation circular arc of two sides plays expansion
Radix Polygalae seed sows the effect of width, and general we obtain the second stopper 922 with stainless steel material through finishing, it is desirable that
Upper surface towards Radix Polygalae seeds fall needs within surface accuracy 6.3, and Radix Polygalae seed is avoided to be accumulated here with soil here
Adhesion influences the whereabouts of seed, and the second stopper 922 adjusts relative position by rotation bolt 9221, realizes adjustment Radix Polygalae kind
Son sowing width, meets different plantation needs.
Traction device is 35~50 horsepowers of four-wheel tractors, it is desirable that wheel back gauge (outermost) is not to be exceeded 1350 millimeters, will be remote
First hitch frame 2 of the dedicated rotary sowing machine of will is connect with tractor, with the traveling of tractor, and rationally controls gear and speed,
It drives the present apparatus to move ahead, realizes that rotary tillage, trench digging, sowing, suppression operation are once completed.
We test gained, the key points for operation that operator of farm machinery needs to pay attention in seeding process:
1, the existing mating power of this type is 500 four-wheel tractor of prosperous magnificent Mount Taishan, and compound type of power, size is matched
Set requires；
2, operator of farm machinery uses low 4 gear, full throttle in operation, purpose:
(1) rotary cultivator revolving speed is higher, and travel speed is slower, and rotary tillage effect is better, so gear is lower, throttle is bigger, effect
Fruit is better；
(2) sowing mechanism requires travel speed very fast, drives chain 16 to make seeding by land wheel 14 and ground friction transmission
Device 8 rotates, and the rotation of feed mechanism for seed 8 is faster, and seeds fall speed is faster, and seed can be preferably broken up after colliding with stopper
The fluidic structures formed in dropping process, so that dispersibility is more preferable when seed being made to pass through the exit of seeder second part 92；
By the above two o'clock comprehensive analysis, if gear is excessively high, seeded dispersion effect is good, but rotary tillage effect is poor, and is broadcasting
Difficulty is higher when kind depth adjustment；If gear is too low, rotary tillage effect is good, but seeded dispersion is poor.Therefore low 4 are used in operation
Gear, full throttle, by our experimental verifications, operating efficiency is advisable with 7~8 mu per hour.
3, operator of farm machinery wants the moment to pay attention to depth of planting in traveling operating process, is adjusted, is broadcast in time by hydraulic lifting arm
Kind effect requirements are that Radix Polygalae seed is uniformly distributed on ground, and the small hoary hair at the top of seed and ground maintain an equal level, and naked eyes are as it can be seen that seed belt
In soil, naked eyes are invisible for grey parts plantation villous, this point is particularly important, and operation difficulty is larger, press wheel suppression
Sowing face is smooth afterwards, consolidation.
Beneficial effects of the present invention are as follows:
The dedicated rotary sowing machine of Radix Polygalae provided by the invention, poor flatness when being able to solve tillage operation in the prior art are abolished
Soil hardening layer effect is unobvious；Seeded dispersion is poor when seeding operation, on ground to be unevenly distributed in certain wide format
Ground problem.The present invention can fully break soil hardening by the way that rotary tillage mechanism 3 is arranged in front of ditcher mechanism 6, sowing mechanism
Layer, and can preferably ground grading so that trench digging, sowing, the work surface that is contacted with soil of suppression cargo handling operation Zhong Ge mechanism all
In one plane, guarantee continuity, the planarization in sowing face, and can greatly reduce labor intensity, improve operating efficiency.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
Determine or deduce out many other variations or modifications consistent with the principles of the invention.Therefore, the scope of the present invention is understood that and recognizes
It is set to and covers all such other variations or modifications.
