Obtain extensive research and application.For crops different or of the same race due to the difference of cropping pattern in seeding process, to every cave
The size of grain number and hill spacing will have a different requirements, the hill spacing of existing air-aspiration type hole sowing machine and general per the regulation of cave Seeding Quantity
Completed by the way of seeds sucker and duckbilled component with varying number suction hole is changed, because seeds sucker is arranged on bunch planting
Wheel is internal, and adjustment hill spacing needs that the replacing of seeds sucker could be completed part dismounting into, therefore dismounting is very troublesome, wastes time and energy,
The strong influence using effect of equipment, in addition, in order to improve the flexibility of the adaptability of seeding machinery and operation, it is necessary to set
The seeding machinery of meter can be realized fast, easily in operation to taking kind of a grain number, hill spacing to carry out effectively under different planting requirements
Regulation.
The content of the invention
The utility model is to avoid the weak point present in above-mentioned prior art, there is provided a kind of driving lever aspirated-air type takes
Kind device, the device can pass through quick-replaceable regulating block of different shapes or increase and decrease according to the requirement of cropping pattern and Seeding Quantity
Regulation number of blocks changes the residence time of the rotation position of plectrum and speed, so as to control be adjustable into the opening of tracheae,
The interval time closed, so as to effectively realize the change of every cave Seeding Quantity and sowing hill spacing in seeding process.
The utility model adopts the following technical scheme that to solve technical problem：
A kind of driving lever air-suction type seed metering device of the utility model is structurally characterized in that：
Seeder sets and is adjustable into tracheae（1）, it is described to be adjustable into tracheae（1）Upper end connects with seeder original air inlet pipe, under

A kind of design feature of driving lever air-suction type seed metering device of the utility model is lain also in：The driving lever composition（2）By driving lever
（21）, plectrum（22）, torsion spring（23）And briquetting（24）Composition, the driving lever（21）With plectrum（22）It is affixed, the torsion spring（23）
It is enclosed on driving lever（21）On, its one end, which is fixed in, is adjustable into tracheae（1）On, the other end is fixed in briquetting（24）On, the briquetting
（24）It is fixed in driving lever（21）End.
Compared with the prior art, the utility model has the beneficial effect that：
1st, the utility model overall structure is simply novel, easy to operate, time saving and energy saving；Suitable for large seeds such as peanuts
Precision drilling, it can quickly carry out assembly and disassembly increase and decrease regulating block number and realize sowing hill spacing regulation, improve seeding quality, lighten one's labor
Intensity, improve sowing efficiency.
2nd, the utility model is using adjustable air intake tubular construction and driving lever composition structure, by effective cooperation with regulating block,
The adjustability of sowing is have effectively achieved, so as to effectively realize every cave Seeding Quantity in seeding process and sow changing for hill spacing
Become.

Fig. 2 is the utility model side view complete section structural representation；
Fig. 3 is that the utility model driving lever forms structural representation；
Label in figure：1 is adjustable into tracheae, 2 driving levers composition, 3 regulating blocks, 21 driving levers, 22 plectrums, 23 torsion springs, 24 briquettings.
Embodiment
A kind of driving lever air-suction type seed metering device of the utility model is structurally characterized in that：
Referring to Fig. 1 and Fig. 2, seeder sets and is adjustable into tracheae 1, described to be adjustable into the upper end of tracheae 1 and seeder original air inlet
Pipe connects, and lower end communicates with seeder air chamber cavity of resorption, and described be adjustable on tracheae 1 sets through hole to install driving lever composition 2；Seeder
Regulating block 3 is set to can extrude the open and close that the driving lever composition 2 makes its rotation control be adjustable into tracheae 1 on cylinder wall.
In specific implementation, as shown in Figures 2 and 3, the driving lever composition 2 is by driving lever 21, plectrum 22, torsion spring 23 and briquetting
24 compositions, the driving lever 21 and plectrum 22 are affixed, and the torsion spring 23 is enclosed on driving lever 21, and its one end, which is fixed in, is adjustable into tracheae 1
On, the other end is fixed on briquetting 24, and the briquetting 24 is fixed in the end of driving lever 21.
Operating process：
Before sowing, according to the requirement of cropping pattern and Seeding Quantity, respective numbers are installed on the cylinder wall of seeder
With the regulating block 3 of shape（When the speed of roller and the rotating speed of seeds sucker are all constant, the regulation installed on the same circumference of cylinder wall
Block 3 is fewer, and the hill spacing of sowing is bigger；When regulating block 3 promotes driving lever composition 2 to rotate the pass for making the control of plectrum 22 be adjustable into tracheae 1
Close, the time of the longer i.e. cut-out source of the gas of closing residence time is longer, more per seed number per）, so as to realize in seeding process
Adjustment to sowing hill spacing and per seed number per.
During sowing, with the operation of seeder, equipment traction hole sowing wheel rotates, and drives seeds sucker is relative to plant by power transmission shaft
Seed cell, air chamber are rotated, while air inlet pipe and regulation air inlet pipe 1 are all ventilated, and are had suction function in such air chamber upper and lower cavity body, are inhaled
Seed and seed chamber is taken it out in the abundant absorbed seed room of discharge plate, when seeds sucker goes to air chamber lower area, due to rotating
Side plates on cable reel in the presence of regulating block 3, make the rotation of driving lever 21 drive the rotary closing of plectrum 22 to be adjustable into tracheae 1, that is, cut off
Lower chamber source of the gas, now cavity of resorption is non-real dead zone, is disappeared when seeds sucker goes to the non-real dead zone of cavity of resorption due to inhaling kind of negative pressure, seed
Fallen by deadweight, realize seeding process, when regulating block 3 leaves driving lever 21, resetted plectrum 22 by the effect of torsion spring and beat
Open, air chamber lower chamber recovers negative pressure, when seeds sucker turns over the region, passes through because suction function continues absorbed seed.
