Specific embodiment
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited
In this.
Embodiment one:
A kind of rice precise direct-seeding cavitation device, including shell 1, at hole tray 2 and transmission shaft 3, be provided with circle in shell
Disk chamber 4, is installed in circular disk cavity at hole tray, includes with the interconnecting piece of transmission axis connection and on the outside of the interconnecting piece in putting at hole tray
Multiple separate space plates 5 of shape stretching are penetrated, form kind of a chamber 6, circular disk cavity top between the cavity wall of circular disk cavity between two neighboring separate space plate
The seed entrance entered in kind of chamber for seed is offered, it is defeated that circular disk cavity lower part offers the seed exported for the seed in kind of chamber
Outlet, when seed entrance is connected to kind chamber, seed enters in kind of chamber through seed entrance, when kind of chamber is connected to seed delivery outlet
When, the seed planted in chamber is exported from seed delivery outlet.
Preferably, the shell includes physa seat 7, annulus plate 8 and cover board 9, and annulus plate is set in round susceptor edges,
Cover plate lid is together on annulus plate, surrounding the circular disk cavity, the seed entrance and kind between annulus plate, physa seat and annulus plate
Sub- delivery outlet is provided with respectively on annulus plate.
Preferably, it is extended with connection otic placode 10 on the outside of the annulus plate, is provided on the outside of cover board and is connect with connection otic placode
Otic placode 11.
Preferably, the axis hole 12 passed through for transmission shaft is offered in the middle part of the physa seat and cover board.
It preferably, further include grain conductor connector 13, grain conductor connector is installed on seed entrance.
It preferably, further include seed delivery line 14, seed delivery line is installed on seed delivery outlet.
It preferably, further include kind of a cavity space regulating mechanism, kind cavity space regulating mechanism includes uniformly being provided with outside interconnecting piece
Multiple mounting grooves 15 being packed into for separate space plate on periphery, separate space plate is encased in the mounting groove of setting, so as to adjust kind of a chamber
Shapes and sizes.
Described kind of chamber shape is that top opening is greater than the trapezoidal of bottom.Trapezoidal at kind of chamber, trapezoidal angle is according to seed rice
Angle of repose design, convenient for filling kind and seeding.
Preferably, side is set as vertical plane to the separate space plate clockwise, and the other side is to vertical plane
Inclined-plane forms described kind of chamber between the inclined-plane of one separate space plate, the vertical plane of another separate space plate and the cavity wall of circular disk cavity.This various chamber is set
Kind of a chamber opening can be increased by setting, to increase the time that kind of chamber is connected to seed entrance, to reach convenient for filling the effect of kind with seeding
Fruit.
Preferably, hairbrush 17 is provided in the seed export of the grain conductor connector.
The course of work and working principle of the invention:
In use, transmission shaft rotation drives and rotates in circular disk cavity at hole tray, when kind of a chamber turns to below seed entrance,
Kind chamber is connected to seed entrance, at this point, seed enters in kind of chamber through seed entrance, with the rotation at hole tray, plants chamber and kind
Sub- entrance is staggered, and kind chamber forms a closed separate chamber, and seed rotates in kind of chamber at hole tray at this time, until kind chamber and position
When the seed delivery outlet connection of lower part, under the effect of gravity, seed is discharged through seed delivery outlet rapidly, to make seed rice in field
Between cavitation be distributed, reach the requirement of rice precise hole sowing.And in a kind of chamber after seed entrance, with hole tray in circular disk cavity
Rotation, another kind of adjacent chamber are connected to seed entrance, are realized the loading to another chamber seed, are so recycled.Also thus
As it can be seen that the present invention is that seed is transported to seed delivery outlet after receiving seed by kind of chamber to be then exhausted from, it is defeated when so that seed being discharged
Distance is substantially reduced out, and it is whole all by under self gravity to being discharged from seed delivery outlet from seed entrance is entered to avoid seed
Fall, since seed is from seed entrance is entered to the dropping process from seed delivery outlet Jing Guo a relatively long distance, this is resulted in
When seed falls process, since overlong time or seed delivery outlet opening time are short, seed has not arrived seed delivery outlet, seed
The case where delivery outlet is shut off, and is made seed generate delay, is led to broadcast leakage or repeat sowing generation；
The seed of delay is overturn in the chamber, when seed delivery outlet is again turned on, it is also possible to be only Some seeds
From seed delivery outlet output (amount number depending on how many seed on seed delivery outlet be at that time, other parts and be spread out in seed
By delivery outlet, do not drop out delivery outlet), remainder seed be also possible to be detained in the chamber, and this Some seeds then with newly into
The seed come is superimposed, and results in the amount exported every time to be all difficult to control in this way, sometimes even without seed, this is all serious
Affect the effect of sowing.
And the present invention is exported through seed delivery outlet again by the way that seed to be transported to after seed delivery outlet, avoids the mistake fallen
Journey enables seed to export rapidly when seed delivery outlet is opened, and can be by adjusting the revolving speed of transmission shaft, to control
The discharge of grain weight processed, and guarantee all seed-bearing output when seed delivery outlet is opened each time, it is seen that the present invention can achieve
Accurately, essence amount, the effect of cavitation sowing.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
