Description
Technical field
The present invention relates to campaign-styled sieve fields.
Background technique
Seed is before being sowed, and in order to preferably there is kind, usually requires the big and full seed of selection grain and is sowed.
Especially for seeds such as peanut, corn, peas, granularity and the inadequate seed of plumpness, not only survival rate is low, and due to losing
Characteristic is passed, the fruit born after the rice shoot plantation grown is also relatively small.
The method that common sieve plants seed selection is that the seed for not meeting granularity and plumpness condition is selected in craft more than, this
The screening efficiency of sample is extremely low, is not suitable for the screening of high-volume seed.
Summary of the invention
The invention is intended to provide a kind of seed screening plant, to filter out the big seed of particle in large quantity.
Seed screening plant in this programme, including screening machine and screening ball, the screening machine includes screen cylinder, blender
The driver of structure and driving rabbling mechanism rotation, screen cylinder are vertically arranged, and rabbling mechanism includes agitating shaft and helical blade, stirring
Axis is rotatably connected on screen cylinder, and helical blade is mounted on agitating shaft, and helical blade is located in screen cylinder, driver and shaft
Connection, helical blade upward precession when driver drive shaft rotates；The screening ball inner hollow screens ball by two hemisphere
Mutually fasten, screening ball be equipped with two hemisphere are locked together and the latching device that remains closed, on the hemisphere
The through-hole opened up according to the granule size of the required seed selected, through-hole are equipped with flexible valve, and valve covering is logical
The area in hole is no more than the 1/2 of through hole section；Screen cylinder bottom is equipped with discharge port, and sieve is equipped with below discharge port, is set on sieve
There is sieve pore, the diameter of sieve pore is greater than the through-hole on screening ball and is less than the diameter of screening ball.
The technical principle of this programme and having the beneficial effect that will need the seed that screens and screening ball to be poured into screen cylinder together
In, the through-hole diameter screened on ball determines that the seed that particle is greater than through-hole diameter can not then be worn according to the seed diameter being screened
The through-hole being sieved on choosing shuttles.The constantly upward precession of driver drives helical blade constantly stirs seed upwards during precession
With screening ball, during agitation, screens between ball and screening ball, screen ball and be screened mutual extrusion between seed.It is less than
The seed of through-hole diameter is squeezed into screening ball since the mutual extruding force of screening ball overcomes the barrier force of valve, and
The big seed of full grains, particle then cannot be introduced into screening ball.After stirring a period of time, stops driver, ball will be screened
It is released together from discharge port with the seed after screening, the sieve below discharge port will screen ball and separate with seed, obtained seed
The as big seed of particle, but the seed for being less than through-hole is then present in screening ball, opens the latching device on screening ball, i.e.,
Screening ball can be separated, not big enough the seed of particle therein is removed.
This programme can once screen large quantities of seeds, be suitble to produce in enormous quantities.
Further, it is additionally provided with lubricating cylinder above the screen cylinder, lubricating cylinder is connected to the screen cylinder, and the shaft extends
To lubricating cylinder, and the shaft being located in lubricating cylinder is equipped with stirring rod.Screening ball and seed to be screened are poured into lubricating cylinder
In, and vegetable oil is mixed, during driver drive shaft, screening ball, seed to be screened and vegetable oil are stirred together
It mixes, makes to form oil film on screening ball and the surface of the seed to be screened, the friction between reduction screening ball and seed to be screened, one
It is easy for seed to enter in screening ball by through-hole, second is that reducing the abrasion between screening ball and seed to be screened, avoid
Screen ball milling bad species.
Further, the screen cylinder bottom is equipped with material collecting tank, and material collecting tank is connected to screen cylinder, and helical blade extends downward into collection
In hopper.The setting of material collecting tank is so that the seed being screened is fallen in material collecting tank automatically under gravity, then by spiral
Blade stirs upwards, guarantees screening effect so that seed moves repeatedly in screening tank convenient for effectively agitation seed.
Further, the decorative pearl on top of an official cap is equipped in the screening ball, the diameter of the decorative pearl on top of an official cap is greater than through-hole diameter, fixes on the outer surface of the decorative pearl on top of an official cap
There are several mandrils, the diameter of mandril is less than the diameter of through-hole, and the length of mandril is greater than the thickness of screening ball.When seed and through-hole
Diameter be just equal to through-hole diameter or slightly larger than through-hole diameter when, seed may be stuck on through-hole, shake the decorative pearl on top of an official cap at this time,
The seed being stuck on through-hole is ejected using the mandril on the decorative pearl on top of an official cap.
Further, the bottom of material collecting tank is arranged in the discharge port, and discharge port is equipped with gate valve.It is closed when screening seed
Gate valve opens gate valve after the completion of screening and releases screening ball and seed.
Further, hinged by hinge between two hemisphere of the screening ball, far from hinge on one of hemisphere
Side is equipped with magnet, and the side far from hinge is equipped with the iron block that can attract with magnet on another hemisphere.Using magnet with
Attraction between iron block keeps screening ball closure, easy to operate using simple.
