Description
Technical field
The utility model belongs to agricultural seeder engineering device technique field, specifically provides a kind of overturning signed-off sample spoon formula seeding
Device.
Background technique
The seeding process of crops exactly separates simple grain or several seeds from cluster, according still further to certain rule
Lattice are placed in soil or matrix.One excellent mechanical planting will meet following basic demand simultaneously：（1）According to various Crop Species
Shape, the size, the difference of surface characteristics of son, design corresponding seed fetching equipment, to separate seed；（2）Seed fetching equipment
The grain number of seed is taken out every time and takes kind of number relative constant in the unit time, meanwhile, take kind of an amount will be with machine travel speed phase
Matching, to guarantee suitable density（Spacing in the rows）；（3）Seed-taking device, which must assure that, can continuously take kind, in order to avoid there is broadcast leakage；
（4）Since seeder working environment is severe, need to cause in face of substances such as sandstone, soil, mud, dust, fertilizer, field rubbish
The scenes such as blocking, collision, adhesion, it is therefore desirable to which machine part is wear-resistant, convenient maintenance and replacement, user can voluntarily be disposed
Various failures avoid influencing peasant's sowing, delay farming season；（5）Machine low manufacture cost, it is cheap, it is bought convenient for peasant；
（6）A seeder simultaneously there are many model, so as to existing tractor, and it is easy to connect.
Currently, relatively conventional feed mechanism for seed is disk spoon formula feed mechanism for seed and chain spoon formula feed mechanism for seed on the market.Disk spoon formula
The structure of feed mechanism for seed is referring to patent " ginseng feed mechanism for seed "（The patent No. 201410103586.4）.The feed mechanism for seed is pacified in disk periphery
Dress takes kind of a spoon, and other side release is gone to after taking out seed by the rotation of disk；Have the shortcomings that application rate is difficult to control, example
Such as, when needing biggish thickness of sowing, the problem of needing disk to run at high speed, bringing in this way is, the seed in spoon may be
It is thrown out under the action of centrifugal force；On the other hand, to this rough surface of rice, character is irregular, the biggish seed of length-width ratio,
It is at random, to be difficult to determine the shapes and sizes for taking kind of spoon, if seed is to enter spoon with the same direction into the angle in spoon
Interior, lesser spoon slot can once take 3-4 seeds, when seed enters spoon slot with 3 or more angles, may there was only one
Grain seed stays in spoon；On the contrary, if may sometimes be taken 2-3 seeds with a biggish spoon, may sometimes be taken 7-
8 seeds cause sowing very uneven, are not able to satisfy the needs of precision drilling.In addition, what the seeder used is all dedicated portion
Part needs to produce by mold, higher cost.The result of chain spoon formula feed mechanism for seed is referring to patent " chain spoon formula Sowing machine for potatoes
Vibrate dispenser "（The patent No. 201220705417.4）.The seeding spoon of the seeder is mounted on chain, and overall structure is more
Complexity, production, maintenance difficult；And the distance of seed walking is longer, when sowing, the shaking of machine may be such that the seed in spoon falls
Out.In addition, requirement of the above two feed mechanism for seed to seed-box is all very stringent, the seed of seed-box is preferably always in same
In plane, if too many, discharge plate or chain spoon can be flooded, is taken kind very much；If very little, take less than kind, therefore, seed-box
Actually it is divided into two-part, that is, top is to contain plants case, and lower part is to take kind of a room, and centre is separated with partition, shifted by Sheng plants case
To taking the seed flow of kind of room to take kind of amount almost the same with take kind of spoon, it just can guarantee that sowing is uniform.
Utility model content
The purpose of the utility model is to overcome drawbacks described above, provide a kind of overturning signed-off sample spoon formula for being more advantageous to popularization and application
Feed mechanism for seed.
