Description
Technical field
The present invention relates to a kind of seeding apparatus, are a kind of air duct seed selection accurate seeding apparatus of Scroll type hole specifically.
Background technique
Document number is CN208987276U, and publication date is that the Chinese patent literature on June 18th, 2019 discloses a kind of machine
The accurate seeding apparatus of tool flatly moving type abnormity seed simple grain, there are following technical problems:
1) in seed selection link, separatory vessel is circular configuration, and cloth hole efficiency is lower, underuses space, it may occur however that
Separatory vessel gives the problem for filling plants case seed supply deficiency；The seed of selection need to remove the impurity such as sandy soil dust in advance, increase work
Amount；
2) in filling kind of link, plants case is filled using four eccentric wheel type structural supports, it is more demanding to installation accuracy, if going out
Existing installation error, since one of them is driving wheel, excess-three is driving wheel, and at work, Yi Fasheng locking phenomenon influences to set
Standby reliability and stability, have and lose risk in advance；For different seed demands, if replacement accentric support, which is adjusted, fills returning for plants case
Turn diameter, four accentric supports need to be replaced simultaneously, considerably increase the requirement to installation accuracy；
3) it plant-unloads kind in linking link filling, upper cover plate and bottom sheet reset are completely dependent on reset spring, and reliability is difficult to
Guarantee；Upper cover plate and lower plate material are opaque, are not easy to state of observation seed during filling kind and unloading kind.
Summary of the invention
The object of the present invention is to provide a kind of air duct seed selection accurate seeding apparatus of Scroll type hole；
In seed selection link: separatory vessel is square structure, and enlarged pore size distribution density makes full use of space, avoids generating
Separatory vessel gives the problem for filling plants case seed supply deficiency；Funnel, blower, delivery pipe and separatory vessel are used cooperatively, and can once be completed
Clear kind and seed selection operation, to obtain the seed for meeting sowing and requiring.After seed feeding, through air flow cleaning, it is light miscellaneous to remove dust etc.
Matter flows into separatory vessel through delivery pipe, selects and is suitble to fill the seed of plants case type hole size and falls into and fill plants case, by clearing up and sorting
Seed, the service performance of mechanism can be greatly promoted, avoid because impurity block caused by shut down processing phenomenon；
In filling kind of link: replacing other three accentric supports using support slide plate, greatly reduce to installation accuracy
High request can avoid that locking phenomenon occurs, guarantee equipment dependability and stability；For different seed demands, one is only needed to change
A accentric support greatly reduces the requirement to installation accuracy, while saving material.
It plant-is unloaded in kind of linking link filling: having abandoned cam mechanism, avoided the mechanism generated using reset spring unreliable
Problem；Using the spool structure of type hole is distributed with instead of upper cover plate, lower plate and enabling shutdown mechanism, smart structural design；
Spool controls precisely operation by double wedge disk, fills kind and seeding process is able to periodically be connected, it can be achieved that continuous work；Spool uses
Elastic apparent material, convenient for observing the motion state of seed during filling kind and unloading kind.

Type hole on double wedge and spool 28 corresponds, for accurately controlling the movement of spool 28；Spool 28, which is mounted on, fills 10 bottom of plants case
In portion's guide groove, attached drawing does not do detailed displaying to this；Fill kind --- the basic principle unloaded kind can be found in be cited in background technique
CN208987276U；Planting frame is fixed on the rack.Referring to Fig. 1, planting platform 18 is fixed on planting rack 19, in planting platform 18
Pipeline is corresponded with lower plate type hole and 20 cavities of hole tray respectively.
The course of work: starting driving motor imparts power to accentric support by gear one and the engagement of gear two, eccentric
Support rotates and fills plants case by support frame and support slide plate drive and do the circumnutation of horizontal circle week, at the same time level-one second level three
Grade separatory vessel simultaneously do the circumnutation of horizontal circle week, meet fill plants case type hole size seed fall into fill plants case complete grder man
Make；Population is cooked plane circumnutation filling in plants case, therebetween, is met and is filled the seed of plants case bottom surface type hole size and fall in type hole,
Kind of a job is filled in completion；Linking axis rotation is driven by shaft coupling after small machine starting, the type on double wedge and spool on double wedge disk
Hole corresponds, and accurately controls the movement of spool, when the type hole of reel upper is with filling that type hole is aligned in plants case, spool lower part
Type hole is staggered with plants case type hole is filled, and the seed for meeting type hole size at this time, which is fallen into, to be filled in plants case type hole, completes seed-filling process, works as volume
The type hole of axis lower part is with when filling that type hole is aligned in plants case, and reel upper type hole is staggered with plants case type hole is filled, and seed is fallen on down at this time
Hole tray is fallen to by planting platform internal pipeline in bottom plate type hole, completes seeding process；Spool controls precisely operation by double wedge disk, fills
Kind and seeding process are able to be connected, it can be achieved that continuous work.
Planting mechanism section:
Referring to Fig. 1, planting frame is fixed on the rack；Planting platform 18 is fixed on planting frame, 18 interior conduit of planting platform difference
It is corresponded with lower plate type hole and 20 cavities of hole tray.
The course of work: seed falls in lower plate type hole and falls to hole tray 20 by 18 internal pipeline of planting platform, completes sowing
Process.
Embodiment two:
The present embodiment is directed to that cavities size is larger or the seed of low-density sowing, such as vegetable seeds etc., this implementation
The difference of example and embodiment one is: being not provided with planting frame and planting platform.Referring to Fig. 7, fills 10 lower part of plants case and hole tray is directly set.
Vegetable seeds such as seed, such as cucumber, tomato, capsicum mainly for low-density sowing etc., select the lesser bias of eccentricity
The seed-filling process of low amplitude high frequency is completed in support, after seed is fallen into lower plate sieve pore, projects model in cavities size always
Compound motion is done in enclosing, when then lower plate opens the door for upper cover plate shutdown, seed freely falling body is dropped down onto cavities, completes seeding process；
About the movement for filling the upper and lower bottom plate enabling shutdown mechanism of plants case, the immediate prior art being cited in background technique is seen.
The present embodiment has abandoned planting platform and planting horse structure, saves material, reduces installation difficulty；Hole tray is under
It is closer between bottom plate, reduces the uncontrolled stroke of seed, avoid seed since initial velocity and freely falling body are apart from too long and winged
Cavities range out；After shortening the distance between hole tray and lower plate, keep overall structure more compact.
Remaining is the same as embodiment one.
Above two embodiments are the preferred embodiment of the present invention, and those of ordinary skill in the art can also be basic herein
Upper to carry out various transformation or improvement, under the premise of not departing from the present invention total design, these transformation or improve all be should belong to
Within the scope of protection of present invention.
