Description
Technical field
The present invention relates to a kind of Precision Seeding feed mechanism for seed, be specifically related to a kind of nest eye wheel type Precision Seeding feed mechanism for seed, belong to agro-farming mechanical technique neck
Territory.
Background technology
Pocket wheel feed mechanism for seed is that one applies mechanical type Precision Seeding feed mechanism for seed earlier, and the pocket on feed mechanism for seed is a fixed groove,
During seeding is crossed, some seeds are liable to stick in pocket owing to water content is more, thus cause broadcast leakage, affect seeding precision；
In order to make seed discharge smoothly, the ratio that the degree of depth of pocket is generally arranged is shallower, so easily make when filling kind seed jump out pocket it
Outer thus cause hole, affect seeding quality.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of nest eye wheel type Precision Seeding feed mechanism for seed, can reduce the seeding rate of seed and crush
Rate, improves seeding precision and seeding quality.
The technical scheme used to achieve these goals: a kind of nest eye wheel type Precision Seeding feed mechanism for seed, including pocket wheel, seeding box
And driving means, pocket wheel is arranged on feed shaft, and driving means drives the rotation of feed shaft, on the excircle of said pocket wheel
The uniform some grooves of circumference, are provided with some exhausting holes vertically in groove, V-groove, pocket wheel inner chamber are processed in the bottom of through hole
There is some steel balls, the diameter of the steel ball big opening size less than V-groove and the little opening size more than V-groove in wall；
The upper end of pocket wheel also has and scrapes kind of a dish, described in scrape the uniform some sizes taking turns upper groove with pocket of the circumference of kind of dish and cooperate recessed
Groove, is fixed with dish axle in seeding box, scraping kind of dish can rotate freely by drum axle.
Adhere to seed in the pocket of pocket wheel be because seed moisture content and hang the extruding produced when planting and the adhesion produced, work as adhesion
Power then sticks in pocket when being more than the gravity of single, and therefore pocket is processed into through hole, and the small ball in pocket wheel is taken turns in pocket
Can produce centrifugal impulse force in rotary course, described impulse force is plus a thrust of the gravity composition promotion planting of steel ball, and thrust overcomes
The adhesion of seed makes each seed can planting smoothly；Pocket wheel drives while rotating and scrapes kind of a disc spins, scrapes on kind of dish
Groove and pocket wheel on groove engage each other thus oppress the gravity on pocket is taken turns and fill kind smoothly, substantially increase and fill kind
Rate.
Further, described in scrape kind of dish and can move along dish Axial and radial, and fixed by stopping means.Scrape the radial direction position of kind of dish
Put the sowing quantity to seeder and seed size is relevant, thus realize sowing the seed of varying number requirement.
Further, in pocket takes turns groove, the size between each exhausting hole is different.On pocket wheel, various sizes of nest is set
Eye, therefore seeder can realize the Precision Seeding function of seed of different seed size, improves the versatility of seeder.
Further, scrape kind of dish to be arranged on dish axle by bearing.
Further, described driving means is arranged in complete machine frame by quadric chain.Quadric chain can ensure that and drives
The land wheel of dynamic device touches with ground all the time, thus ensures the rotation seeding that pocket is taken turns.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of nest eye wheel type Precision Seeding feed mechanism for seed, including pocket wheel 1, seeding box 2 and driving means 3, pocket is taken turns
1 is arranged on feed shaft 4, and driving means 3 drives the rotation of feed shaft 4, and on the excircle of said pocket wheel 1, circumference is uniform
Some grooves 11, are provided with some exhausting holes vertically in groove, V-groove, tool in pocket wheel internal chamber wall are processed in the bottom of through hole
There are some steel balls 5, the diameter of the steel ball 5 big opening size less than V-groove and the little opening size more than V-groove；Nest
The upper end of eye wheel 1 also has and scrapes kind of dish 6, described in scrape the uniform some sizes taking turns 1 upper groove with pocket of the circumference of kind of dish 6 mutual
Fit, is fixed with dish axle 7 in seeding box 2, scraping kind of dish 6 can rotate freely by drum axle 7.
Adhere to seed in the pocket of pocket wheel be because seed moisture content and hang the extruding produced when planting and the adhesion produced, work as adhesion
Power then sticks in pocket when being more than the gravity of single, and therefore pocket is processed into through hole, and the small ball in pocket wheel is taken turns in pocket
Can produce centrifugal impulse force in rotary course, described impulse force is plus a thrust of the gravity composition promotion planting of steel ball, and thrust overcomes
The adhesion of seed makes each seed can planting smoothly；Pocket wheel drives while rotating and scrapes kind of a disc spins, scrapes on kind of dish
Groove and pocket wheel on groove engage each other thus oppress the gravity on pocket is taken turns and fill kind smoothly, substantially increase and fill kind
Rate.
Further, described in scrape kind of dish 6 and can move radially along dish axle 7, and fixed by stopping means.Scrape the footpath of kind of dish
Relevant to the sowing quantity of seeder and seed size to position, thus realize sowing the seed of varying number requirement.
Further, pocket in taking turns 1 groove size between each exhausting hole different.On pocket wheel 1, different size is set
Pocket, therefore seeder can realize the Precision Seeding function of seed of different seed size, improves the versatility of seeder.
Further, scrape kind of dish 6 to be arranged on dish axle 7 by bearing.
Further, described driving means 3 is arranged in complete machine frame 8 by quadric chain 9.Quadric chain 9 can
To ensure that the land wheel of driving means touches with ground all the time, thus ensure the rotation seeding that pocket is taken turns.
Illustrate the work process of this device in detail below,
During the work of nest eye wheel type Precision Seeding feed mechanism for seed, driving means moves ahead with tractor and rotates counterclockwise, and power is passed through chain
Passing to pocket wheel 1, pocket wheel 1 rotates counterclockwise and drives scrapes kind of a dish rotation, scrapes kind of dish 6 and will enter the kind in seeding box
The pocket of son press-in pocket wheel successively is interior and scrapes off unnecessary seed, and when certain pocket of pocket wheel 1 is opening down, seed is subject to
The smooth planting of seed is made to impact force action when gravity own, steel ball group and gravity and steel-ball collision；When seed size with
When front-seat pocket size is incompatible, adjusts and scrape kind of wheel and the position of pocket wheel.
Present configuration is simple, can be greatly improved seed-filling rate and planting rate, reduce the breakage rate of seed simultaneously, it is ensured that Precision Seeding matter
Amount.
