Description
Technical field
The invention belongs to agricultural mechanical field, and in particular to a kind of strength nest eye wheel type dispenser.
Background technology
China is small particle seed crop plantation big country, and described small particle seed just refers to that average grain diameter is less than 3mm's
Seed, vegetable seeds is Typical Representative therein.Vegetables are the second important industrial crops for being only second to grain, its kind in China
Plant industry is all the important component of China's agricultural production all the time.With the development of agricultural machinery, it is large quantities of it is advanced can
The mechanical particularly harvest machinery and field management machinery of vegetable cultivation leaned on arises at the historic moment, and drastically increases vegetable cultivation and life
Efficiency is produced, the labor intensity and production cost of peasant is greatly reduced.But, compared to whole vegetable cultivation machineryization level
Fast development, its Mechanization Level for sowing link but lags far behind always, and national large area vegetable cultivation is at seeding time still
Based on artificial, supplemented by small-sized machine drilling, bunch planting.Operating efficiency is low, cost is high, seed skewness, and later stage thinning
Or the labor intensity filled the gaps with seedlings is big, overall economic efficiency is low, limits the expansion that small particle crop seed sows scale.This is main
It is due to the not of uniform size of vegetable seeds not of the same race, the requirement to dispenser is very high, and the costliness of vegetable seeds also limit
Its popularization broadcasted sowing on a large scale.
Domestic seed dispenser is that negative pressure suction is planted mostly, or negative pressure inhales kind of a malleation seeding, but can not be effectively clear
Except unnecessary seedlet or debris, easily there is seeding hole plug and produce broadcast leakage shoot-breaking phenomenon, this is also current all vegetables
The common difficulty that feed mechanism for seed faces.The present invention by for small particle crop seed particle diameter is small, cracky, Precision Seeding is difficult and passes
System feed mechanism for seed one device a line, complex structure and other problems are improved.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of strength pocket suitable for small particle seed
Wheeled dispenser, improve fill kind, take kind and seeding by way of, improve the seeding efficiency of small particle seed in agricultural production
And quality, realize the precise sowing of small particle seed.
The present invention is realized by following technical proposal：
A kind of strength nest eye wheel type dispenser, including kind of case and the feed mechanism for seed that is located at below kind of case, the feed mechanism for seed by
Casing, the seed wheel of box house is located at, box house is located at and the cleaning brush above the seed wheel and is located at casing bottom
The funnel composition of charging seed in portion, the outer surface of the seed wheel is along the circumferential direction evenly provided with two circle indent holes, said pocket hole
Diameter be more than the diameter of seed, the inner surface of the seed wheel is along the circumferential direction provided with two ring annular grooves, the annular groove position
It is less than seed diameter in the middle of indent hole and groove width；A gear, the gear are respectively equipped with two ring annular groove
Just it is meshed positioned at the lower section of seed wheel and with indent hole；The two ends of the seed wheel are respectively equipped with end cap, the end cap
Provided with suction hole, the inside of the seed wheel is provided with atmospheric area and negative pressuren zone, and the suction hole is connected with negative pressuren zone, the gear
In atmospheric area.
The bottom of the casing, which is additionally provided with, unloads kind of a lid.
Kind of an amount adjustable plate is additionally provided with the casing, the kind amount adjustable plate is located at the top of seed wheel.
Maximum improvement of the invention is in seed wheel, and seed enters feed mechanism for seed from kind of a case, due to the row of being provided with feed mechanism for seed
Wheel is planted, seed wheel is provided with indent hole, therefore seed is adsorbed entering in indent hole above seed wheel, due in seed wheel
Wall is provided with annular groove, and the width of annular groove is less than seed diameter, therefore seed will not enter inside seed wheel；Seed wheel rotates
Adsorbed seed is driven to reach below feed mechanism for seed, due to being provided with gear in seed wheel, seed wheel rotation can also revolve with moving gear
Turn, now gear can extrude the seed adsorbed in indent hole, so as to carry out seeding incessantly；Pass through air-breathing in seed wheel
Negative pressure is produced, so that seed is preferably adsorbed in indent hole, and during seeding is malleation, seed is forced to push away by deadweight and gear
Dynamic effect, drops from indent hole and realizes and charge seed, and effectively prevent pocket hole plug.The effect of cleaning brush is in row by absorption
The unnecessary seed for planting wheel outer surface is removed, and is unloaded kind of an effect for lid and is easy for taking out the seed in casing, further prevents indent hole
Block.
The beneficial effects of the invention are as follows：
1) present invention combines two kinds of gravity and aspiration and fills kind of a mode, add seed wheel fill kind of efficiency and fill kind it is reliable
Property；Seed wheel can also be made to be adapted to the requirement of high speed seeding, increase the work of feed mechanism for seed by adjusting the size of negative pressure simultaneously
Make efficiency.
2) present invention is carried out filling kind by the way of aspiration negative pressure and takes kind, compared with traditional machinery fills and plants and take kind,
The damage come to seed belt is reduced, the qualification rate of seeding is increased.
3) two ways of charging seed is forced with reference to gravity and gear, effectively prevent the broadcast leakage caused by pocket hole plug and break
Ridge problem.
