Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
In conjunction with shown in Fig. 1, in one embodiment, a kind of site preparation roller arrangement is provided, including rack 10 and be installed on rack
Roller 20 on 10 and multiple scraping panel assemblies 30,20 surface of roller have protruded out multiple gear rings 40, and multiple gear ring 40 is along roller
20 axial array distribution, each scraping panel assembly 30 correspond respectively between two adjacent gear rings 40, and each gear ring 40 divides
Not Bao Kuo multiple tooth units 401, multiple tooth unit 401 along roller 20 circumferential array be distributed.
It is easy viscous glutinous soil between adjacent gear ring, if removed not in time, the cultivated depth of pears and site preparation roller row can be influenced
Into resistance., can be during traveling by being respectively set between adjacent gear ring with scraping panel assembly, real-time pair roller barrel table
Face soil strikes off.
In one embodiment, the tooth unit 401 of two neighboring gear ring 40 is staggered.
In one embodiment, tooth unit 401 is triangle, and central axes are in 45 ° of angles with 20 surface of roller.
Further, the working face of tooth unit 401 is recessed arc, during site preparation, the tooth unit 401 of 45° angle
Apex angle can preferably first be contacted with ground, then realize that ground pears are cultivated by the working face of arc.
In conjunction with shown in Fig. 2, scraping panel assembly 30 includes linking arm 301, clean-up scraper 302 and locating part 303.
Linking arm 301 is connected to rack 10 and opposite rack 10 is swingable；Clean-up scraper 302 is installed on linking arm 301, and
It is close to by the swing of linking arm 301 or far from 20 surface of roller；Locating part 303 acts on linking arm 301, to adjust scraping
Maximum displacement between 20 surface of plate and roller.
In the technical solution, locating part 303 may act on linking arm 301 to drive clean-up scraper 302 close to or away from roller
20 surfaces are limited when clean-up scraper 302 is lost (distance increases between 20 surface of clean-up scraper edge and roller) by adjusting
Part 303 is effectively increased the utilization rate of clean-up scraper 302, while can have to reduce the distance between clean-up scraper and 20 surface of roller
Effect avoids the influence that linking arm 301 deforms.
In conjunction with shown in Fig. 3, in a preferred embodiment, locating part 303 is a bolt, which rotates so that its end connects
Close or remote from the first surface of linking arm 301, first surface is the surface that linking arm 301 deviates from roller 20.
Rack 10 includes mounting base 101, and the top of linking arm 301 rotates in mounting base 101, is also equipped in mounting base
With the nut 304 of bolt cooperation.
In one embodiment, the screw hole of interior threaded surface can be directly offered in mounting base, but this kind of scheme cost
It is higher.
In a preferred embodiment, mounting base 101 includes two pieces of support plates being oppositely arranged, shape between two pieces of support plates
At there is swing space.
The top of linking arm 301 rotates in swing space；The first window being connected to swing space is offered in support plate
1011, nut 304 is limited in first window 1011；The end of bolt 303 extends in swing space；In first window 1011
It is additionally provided with catch 305, the through-hole worn for bolt is offered on catch 305.
Further, the second window 1012 is offered in support plate, which constitutes the path of travel of bolt.
In the technical solution, when the swing space width between two support plates is smaller, it is less than the diameter of bolt, bolt
It can not be plugged in swing space, therefore, the path of travel of bolt is used as by opening up the second window, the height of the second window is big
In the diameter of bolt.
In one embodiment, catch is U-shaped.
In the technical solution, the catch of U-shaped and the size of first window match, play bolt be oriented to, nut positioning,
And the effect of limitation bolt transverse shifting, avoid the shaking of bolt.
In other embodiments, the shape of catch can also be rectangle, while be opened up respectively for spiral shell on its opposite side wall
The through-hole that bolt passes through.
In the technical solution, support plate, bolt, nut, catch are formed using assembling mode, each component system easy to process
Make, it is at low cost and easy to assembly.
In one embodiment, the bottom end of linking arm 301 is provided with mounting plate 306, and long lumbar hole is offered on mounting plate 306
3061, displacement of the clean-up scraper 302 along long lumbar hole direction is adjustable.
In the technical solution, clean-up scraper is removably mounted to the lower surface of mounting plate by bolt, and can be with by bolt
The position that clean-up scraper is adjusted along long lumbar hole direction can adjust clean-up scraper and protrude out when deterioration occurs for clean-up scraper edge
The length at mounting plate edge.
In other embodiments, clean-up scraper can also be set to the upper surface of mounting plate.
When work, the edge action of clean-up scraper is in the surface of roller 20 to realize that scraping desilts operation.
The operation principle of this case is that tractor is connected to rack and can drag roller rotation, in roller rotation process, tooth
Unit penetrate soil and realize pears plough, roller act under the effect of gravity ground realize it is smooth, in roller rotation process, scraping
Plate relatively rotates with roller surface, since clean-up scraper and roller surface gap are small, can in time scraper surface soil.
The site preparation roller arrangement of this case is suitable for individual site preparation equipment, can also be compound the setting of site preparation and fertilising combination
It is standby.Compound seeder is applied also for, in one embodiment, in addition to site preparation, which can also have plough, base fertilizer to apply fertilizer
Device, seeder, mouth fertilizer fertilizer apparatus, press wheel etc..
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
