Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described.
As shown in Figure 1 and Figure 2, aspirated-air type ratchet precise seeder of the present invention include with
The Sheng kind case 6 of seeding window 4, equipped with blower fan 1 seeding box 2 and be installed on Sheng kind case 6 internal,
Ratchet seed selection device for the seed selection of essence amount.
Wherein, containing bottom kind of case 6 in scalariform, beneficially seed 10 concentrates near ratchet 5,
Ratchet 5 is facilitated to obtain seed in rotation process.
Seeding box 2 is fixedly connected on the back side containing kind of case 6, and seeding box 2 is adjacent with containing kind of case 6
Tank wall top have one and make the through seeding in seeding box 2 and the inner space containing kind of case 6
Window 4.Bottom seeding box 2 tapered, and a protruding pipe is connected with discharging tube 3.Seeding box 2
The top tank wall relative with seeding window 4 on equipped with blower fan 1, the installation site of blower fan 1 and seeding
The position of window 4 is corresponding.The wind-force suitable size of blower fan 1, is guaranteeing seed from containing kind of a case 6
Suck while seeding box 2, can prevent again that wind-force is excessive causes seed to clash into the problems such as blower fan
Produce.
Preferably, seeding window 4 is rectangular, and its place-centric, should in the mounting axis of blower fan
Axis is parallel with the axis of ratchet 5, and tangent with the root circle of ratchet 5.Seeding window 4 big
Little and the teeth groove of ratchet (5) size matches, to ensure when being positioned at ratchet 5 and seeding window 4
When the corresponding seed in teeth groove is sucked seeding box 2 by blower fan 1, remaining seed will not be disturbed.
Ratchet seed selection device includes ratchet 5, back-up ring 7, key 8, axle 9.Axle 9 is through seeding box 2
With contain the hole being correspondingly arranged on kind of case 6, with feed mechanism for seed power supplying apparatus (land wheel or with from dragging
Machine drawing rear power output shaft obtains the decelerator etc. of power) it is connected, provide to ratchet seed selection device
Power, drives ratchet 5 uniform rotation.Ratchet 5 is connected with axle 9 by key 8.Ratchet 5
Distance from bottom contains the bottom 2-4mm of kind of case 6, a teeth groove of ratchet 5 and the position of seeding window 4
Put correspondence, and it is internal to be fixedly mounted on Sheng kind case 6 by back-up ring 7 and the shaft shoulder.Preferably, spine
On wheel 5, the size of teeth groove matches with the size of the seed of acquisition, it is ensured that each tooth once can only
Obtain 1-2 grain seed.
As shown in Figure 2 and Figure 3, aspirated-air type ratchet precise seeder of the present invention operationally,
Seed 10 is placed in Sheng kind case 6, and ratchet seed selection device is with a certain fixed speed uniform rotation.
In rotation process, the toothholder on ratchet 5 takes the seed 10 contained in kind of case 6, and each toothholder takes
1-2 seed, and deliver to, at seeding window 4, work at blower fan 1 by the seed of gripping by rotating
Time produce suction under, the seed 10 on ratchet 5 is entered seeding box 2 by seeding window 4,
It is inhaled into the seed 10 of seeding box 2 under gravity by the pipe of seeding box 2 bottom protrusion
Enter discharging tube 3, smooth seeding.Detailed process is as shown in seeding track 11 in Fig. 2.
Finally it should be noted that above example only in order to technical scheme to be described rather than
Limit, although the present invention being described in detail with reference to preferred embodiment, this area common
It will be appreciated by the skilled person that technical scheme can be modified or equivalent,
Without deviating from the spirit and scope of technical solution of the present invention, it all should contain the right in the present invention
In the middle of claimed range.
