Embodiment：
Referring to accompanying drawing.
A kind of centrifugal disc type hole formula rice extractive quantity hole sowing seeder unit, including it is plants case 1, septum pellucidum kind box 2, feed shaft 3, imitative
Shape type hole 4, kind chamber interior wall projection 5, move back kind of groove 6, L-shaped angle bracket 7, a comb kind bar 8, grain conductor 9, seeding disk 10, scrape kind of a dress
Put 11, seeds pushing device 12；It is characterized in that：Described cylindrical shape plants case 1 is arranged on L-shaped angle bracket 7, in the bottom of plants case 1
A horizontally disposed seeding disk 10 concentric with plants case 1 and a comb kind bar 8, seeding disk are sequentially placed from bottom to top
The bottom interior wall of plants case 1 is close in 10 bottoms, and 4 profiling type holes 4 are circumferentially uniformly arranged on seeding disk 10, and comb kind bar 8 is placed on
Along in 4 raised plates 5 of 1 inwall circle spacing of plants case equal angular, comb kind bar 8 is spaced 10mm with seeding disk 10, in plants case 1
Bottom is provided with 1 rectangle sowing port, and sowing port is connected with grain conductor 9, and the inwall of plants case 1 installs a fold-line-shaped septum pellucidum kind box 2,
The surface of sowing port is in every kind of box 2, is built-in with every kind of a box and scrapes kind of device 11 and seeds pushing device 12, feed shaft 3 revolves during work
Turn to drive seeding disk 10 to rotate, so as to drive seed to sowing port to discharge.
Described comb kind bar 8 is crisscross roundness mess strip, and comb kind bar 8 was placed on along the kind chamber interior wall circle spacing
, can easy removal comb kind bar 8 in 4 raised plates 5 of equal angular；Slice plate interlocks comb kind bar 8 in length and breadth, can prevent seed from broadcasting
Resulted in blockage above kind mouth, rice paddy seed is fallen in order.
The critical component type hole of the seeding disk 10 is to simulate the profiling type hole 4 of spindle rice paddy seed shape, along circle
4 profiling type holes 4 of setting of disk even circumferential, the long side of profiling type hole 4 are parallel with the tangential direction of any on circumference.In disk
Rotated along the direction shown in accompanying drawing 3, enter after type hole has a lead-over groove to be scraped to scrape kind of a tongue from type hole every one end of kind of box 2
Go out unnecessary seed and be easy to push pedal to exit profiling type hole 4 and reduce impact.
Described kind of device 11 of scraping is by scraping kind of tongue 1101, scraping kind of bar 1102, scrape kind of compression spring 1103, trip bolt 1104
Composition, scrapes kind of tongue 1101 and is approximately a horizontal positioned T-shaped and has certain rigidity and elasticity, scrape the width ratio of kind of tongue 1101
The big 2mm of the width of profiling type hole 4, scrape the angle of the bottom-working surface of kind of tongue 1101 and seeding disk 10α=400；Trip bolt 1104 is tight
Admittedly kind of tongue 1101 is scraped every on kind of box 2；Scrape kind of compression spring 1103 and be nested in and scrape on kind of bar 1102, scrape kind of bar 1102 and scrape kind of a tongue
1101 one, when there is seed on the surface of profiling type hole 4, scrapes kind of compression spring 1103 and promote to scrape kind of bar 1102 and make to scrape kind of tongue 1101 and protect
Hold and keep a constant operation distance with seeding disk 10, remove the seed of the excess surface of profiling type hole 4.
Described seeds pushing device 12 is by push pedal 1201, resilient push 1202 and pushes away kind of compression spring 1203 and forms, and pushes away kind of a pressure
Contracting spring 1203 is nested in resilient push 1202, and push pedal 1201 is located at 1202 below resilient push, push pedal 1201 be one to
The arc of lower convexity, the thickness of arc are less than the width 1-2mm for moving back kind of groove 6；When 10 solid position of seeding disk is pushing away
When under plate 1201, kind of compression spring 1203 is pushed away by axial force meeting compression storage deformation energy, when profiling type hole 4 is in push pedal
During 1201 underface, the deformation energy stored before can be discharged by pushing away kind of compression spring 1203, drive push rod 1202 and push pedal 1203
Move downward, the seed in profiling type hole 4 is released in push pedal 1203.
Described fixes every kind of box 2 and is close to the inwall of plants case 1, with static seed-box 1, positioned at the surface of sowing port
Partial disc, the closing space of relative dynamic is formed, be fold-line-shaped every the outside of kind of box 2 and be plastic material, transparent attribute, every kind
Box 2 is opening a small radian so as not to every the scratch seed of kind of box 2 close to scraping the one end of kind of tongue 10 away from disk 2mm, overall from row every kind of box 2
Kind 10 high 1mm of disk is not contacted with seeding disk 10 so as not to increasing friction dynamics.
Specific work process is as follows：
Rice paddy seed is poured into plants case 1 before mechanical work, because deadweight nature falls, seed passes through by plants case rice paddy seed
Wall raised plate 4 support comb kind bar 8 in order under drop down onto on seeding disk 10, Some seeds can be filled with profiling type hole 4, worked
Shi Xuanzhuan feed shaft 3 can drive seeding disk 10 to rotate, and the seed on the seeding disk 10 of rotation is easily filled by centrifugal force
Kind, it is effectively guaranteed seed-filling rate, seeding disk drives the seed movement in profiling type hole 4 and surface during work, treats that seed passes through
The position for scraping kind of tongue 1101 is crossed, kind of compression spring 1103 is scraped and promotes to scrape kind of bar 1102 and make to scrape kind of tongue 1101 and keep and seeding disk 10
A constant operation distance is kept, the seed of the excess surface of profiling type hole 4 can be blown off.Seed in profiling type hole 4 enters every kind
Box 2, when 10 solid position of seeding disk is under push pedal 1201, pushing away kind of compression spring 1203 can compression storage by axial force
Deformation energy, when profiling type hole 4 is in the underface of push pedal 1201, the deformation stored before can be discharged by pushing away kind of compression spring 1203
Can, drive push rod 1202 and push pedal 1203 to move downward, the seed in profiling type hole 4 is released in push pedal 1203, and seed is by leading
Fallen under kind pipe 9 in soil.
