Abstract
The utility model relates to a precision hole sowing mechanism which comprises a fixed wheel body, a rotary wheel body, a wheel shaft and a seed inlet; two sections of orbits with different diameters are arranged in the fixed wheel body, the joint of the orbits are in a smooth transition, a plurality of piston type hole sowing mechanisms are arranged in the rotary wheel, a rolling wheel is arranged on the hole sowing mechanism, and the rolling wheels are uniformly arranged on the orbit with different diameters of the fixed wheel body; a composite structure that the fixed wheel body is buckled with a movable wheel body is used by the utility model. One is movable, the other one is static, a piston type precision hole sowing device is arranged in the movable wheel body, and the hole sowing work with fixed quantity can be exactly carried out.
Description
The utility model relates to a kind of seeding apparatus, specifically is exactly a kind of Precision hill-drop wheel that is used on the sower.
Hole seeding arrangement is the core component of mulch film sower, and traditional dibbler structurally can not be coordinated configuration mostly, is difficult to realize accurately quantitatively sowing, influences the raising of seeding quality and operating efficiency.The branch kind uniformity of above-mentioned grouping mechanism is poor simultaneously, and the seed consumption is big, has not only strengthened production cost, has increased the final singling workload, has also influenced the sane growth of crop seedling phase, and is comparatively unfavorable to increasing both production and income.
In order to overcome above-mentioned weak point, the purpose of this utility model is to provide a kind of rational in infrastructure, easy to adjust, reliable operation, can realize the Precision hill-drop wheel of precise hole sowing.
The purpose of this utility model is achieved in that it comprises fixed wheel body, web, wheel shaft and seed inlet, its characteristics are the built-in two sections reducing tracks of fixed wheel body, the rail connection seamlessly transits, be provided with several pistons formula grouping mechanism in the web, grouping mechanism is provided with roller, and roller distributes on fixed wheel body reducing track equably.
Above-mentioned hole sowing wheel, said piston type grouping mechanism is made of piston, connecting rod, spring, roller and cylinder body, and connecting rod is provided with into kind of amount adjustment hole.
Into kind of amount is constant in order to keep, and the fixed wheel body seed inlet place of above-mentioned hole sowing wheel is provided with hairbrush.
For the ease of regulating amount of seed metering, have adjustment hole at the roller axle head of connecting rod.
The combining structure that the utility model adopts fixed wheel body and driving wheel body to be interlocked, one moving one is quiet, and the driving wheel body is provided with the piston type precise hole sowing device, when the bunch planting operation, can make the seed speed of landing level off to zero, quantitatively implements the bunch planting operation exactly.Because the piston type grouping mechanism has the seeding of pressure function, thereby can not stop up the phenomenon of cavitation mechanism, thereby guarantee the bunch planting quality.
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in detail:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the end view of Fig. 1.
With reference to Fig. 1～2, present embodiment comprises fixed wheel body 3, web 4, wheel shaft 13 and seed inlet 1, fixed wheel body 3 built-in two sections reducing tracks (10,16), track (10,16) junction seamlessly transits, be provided with several pistons formula grouping mechanism in the web 4, grouping mechanism is provided with roller 14, and roller 14 distributes on fixed wheel body 3 reducing tracks (10,16) equably.
The piston type grouping mechanism is made of piston 5, connecting rod 8, spring 7, roller 14 and Sheng kind of a chamber 6, and connecting rod 8 is provided with into kind of amount adjustment hole 15.
Into kind of amount is constant in order to keep, and fixed wheel body 3 seed inlets 1 place is provided with hairbrush 2.
During operation, wheel shaft 13 connects by key 21 with fixed wheel body 3, and is fixed on the body, and web 4 rotates around fixed wheel body 3 by bearing 2, thereby drives the grouping mechanism motion, and concrete working link is: (supposition hole sowing wheel right lateral)
1, essence is measured kind: web 4 lands with fixed wheel body 3, and web directly contacts soil, turns clockwise, and roller 16 is made circular motion at the effect lower edge of web 4 protruding, recessed formula reducing track (10,16).At track 16 places, roller 14 enters protruding rail, and then drivening rod 8, piston 5 experts, and spring 7 is compressed, and forms to contain kind of a chamber 6, and seed is entered by seed inlet 1, and hairbrush 2 brushes away unnecessary seed.
2, the cave is gone in seeding: when precise hole sowing device turns to track 10 places, and roller 14 beginning engagement concavity rails, spring 7 pushes piston 5 at once, discharges seed, is pressed in the soil, thereby makes the seed speed of landing level off to zero, guarantees the bunch planting operation quality.
3, associated components: plough 9 is contained in the front lower place of fixed wheel body 3,11 back lower places that are contained in fixed wheel body 3 of covering device, and during web 4 work, plough 9 and covering device 11 are worked simultaneously.
For the ease of regulating amount of seed metering, have adjustment hole 15 at the roller axle head of connecting rod 8.
The alternative traditional dibbler of the utility model reaches and decides cave, smart amount, do not stop up cavitation mechanism, thereby guarantees the effect of bunch planting precision, is applicable to all kinds of sowers, also can change a social system out people, animal power sower.
