Description
Technical field:
The utility model belongs to agricultural machinery, relates generally to the seeding operation assembly on a kind of seeding machinary.
Background technology:
Studies show that selecting rational soybean culture pattern is an important channel that increases substantially soybean yields.The compact planting in narrow row high-yield culturing has increased density owing to dwindled line-spacing, and it is more reasonable that plant is distributed, thereby increased the photosynthesis area, and more traditional ridge planting generally can increase production more than 20%, is the new technology of a soybean yield-increasing.Therefore, the research of carrying out the seeding machinery that matches with it has crucial meaning.The at present domestic large-scale plane seeder that adopts is most to be import, and the research of small-sized plane seeder is also deficient relatively, accurately follow an example in ground, zero speed of seed dropping, seed level is consistent and be convenient to regulate, suppression power appropriateness, many key issues such as adjustable can not obtain basic solution, cause the research and development of compact planting in narrow row cultivation corollary new seeding machinery slow.
Summary of the invention:
The utility model has designed a kind of compact planting in narrow row air-sucking type precise sowing unit group at the problems referred to above, and purpose is to improve sowing grain spacing evenness, seed level uniformity, realizes the adjustable and accurate profiling of suppression power.
Basic design of the present utility model is that a kind of compact planting in narrow row air-sucking type precise sowing unit group comprises that the cell cube longeron reaches kind case, sowing single-disc colter, air-suction seeding unit, universal covering device and the packing wheel assembly that is fitted in successively on the cell cube longeron; Equipped rear cross beam on the cell cube longeron rear side of two configured in parallel, two Connection Blocks are packed in respectively on two cell cube longeron leading sections, the front beam two ends respectively with two cell cube longerons on Connection Block affixed, the dark land wheel that drives of limit is installed on the downside position in the middle of front beam, and the rear and front end of parallelogram lindage is hinged with Connection Card and Connection Block respectively.
Side at sowing single-disc colter medial surface disposes the seeds protecting plate that matches with the sowing single-disc colter.
Packing wheel assembly is hinged by the suppression wheel carrier and is installed in behind the cell cube longeron on the side lower part, pressure adjusting lever is hinged and is installed on the cell cube longeron rear lateral portion, and with locating groove clamping matching on the cell cube longeron rearward end, the two ends of extension spring are connected with pressure adjusting lever with the suppression wheel carrier respectively.
The utility model adopts technique scheme can accurately control seed level, reduces a height of charging seed, and improves transmission efficiency, thereby has guaranteed the stability of seed level and the uniformity of grain distance, and suppression power is adjustable also to have guaranteed good suppression of soil effect.
Description of drawings:

Piece number explanation among the figure:
1, cell cube longeron 2, kind case 3, parallelogram lindage 4, Connection Card 5, limit drive land wheel 6, Connection Block 7, sowing single-disc colter 8, air-suction seeding unit 9, universal covering device 10, packing wheel assembly 11 deeply, suppress wheel carrier 12, extension spring 13, pressure adjusting lever 14, rear cross beam 15, front beam 16, seeds protecting plate
Embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
A kind of compact planting in narrow row air-sucking type precise sowing unit group, comprise that cell cube longeron 1 reaches the kind case 2 that is fitted in successively on the cell cube longeron 1, sowing single-disc colter 7, air-suction seeding unit 8, universal covering device 9, packing wheel assembly 10, equipped rear cross beam 14 on cell cube longeron 1 rear side of two configured in parallel, two Connection Blocks 6 are packed in respectively on two cell cube longeron 1 leading sections, front beam 15 two ends respectively with two cell cube longerons 1 on Connection Block 6 affixed, the dark land wheel 5 that drives of limit is installed on downside position in the middle of the front beam 15, and the rear and front end of parallelogram lindage 3 is hinged with Connection Card 4 and Connection Block 6 respectively.
Side at sowing single-disc colter 7 medial surfaces disposes the seeds protecting plate 16 that matches with sowing single-disc colter 7.
When compact planting in narrow row air-sucking type precise sowing unit group is worked, tractor-drawn sowing unit group moves ahead, the dark land wheel 5 that drives of limit directly passes to power air-suction seeding unit 8 by one-level chain drive, and sowing unit group is finished trench digging, sowing, earthing and suppression operation successively; Packing wheel assembly 10 suppression power can cooperate the gear groove to regulate by pressure adjusting lever 13; The dark land wheel 5 that drives of limit can accurately be controlled seed level and improve transmission efficiency.
