Description
Technical field
The invention belongs to agricultural mechanical field, the granule materials relating to fertilizer applicator and seeder is sowed, more particularly to one
Kind can apply fertilizer, sow the multi-functional planting machine of dual-purpose Pneumatic type.
Background technology
In mechanization of agriculture produces, fertilizer applicator is using chemical fertilizer as sowing the fertilizer machinery of object, for certain class or certain
Plant the basal dressing of crop and execute seed manure and spraying fertilizer, such as full width type fertilizer applicator, spinning fertilizer.And seeder is with Crop Species
Son is the planting machinery of sowing object, for certain class or the seeder of certain crop, such as grain dill, cotton planter, herds
Grass seed broadcasters etc., therefore apply fertilizer, sow each different fertilizer applicators and seeder of need to using, to complete different farmings.
At present, fertilizer machinery kind is a lot, and fertilizer applicator needs to use with tractor mostly.Centrifugal fertilizer applicator, be
Driven by motor broadcast application dish by rotating utilizes centrifugal force that fertilizer is shed away.Full width type fertilizer applicator, is by transversely arranged row
Have refuse rotor to take fertilizer to defertilizing tube in fertile device to fall down on the farm.
Still suffering from some drawbacks during fertilizer applicator is actually used, spinning fertilizer is shed in sector, and fertilizer cast distribution is not
Enough uniform and the most accurate;Full width type fertilizer applicator is fallen because of fertilizer on soil by gravity, and fertilizer compares concentration, in stack not
Uniformly, and fertilising fabric width and fertilising density are limited to different rotary cultivator, and thus, existing fertilizer applicator effect is undesirable.
During seeder such as drill for sowing in lines operation, road wheel driving seed wheel to rotate, seed application rate on request enters defeated
Planting pipe, seed falls into groove and is then covered by compacting;Aspiration type sowing device, absorption kind under vacuum chamber negative pressure during discharge plate revolution
Son, seed produces vacuum chamber and leans on from flumping in ditch, there is sowing and broadcast sowing uneven in same sowing, and seed waste etc. is seriously asked
Topic, is limited to feed mechanism for seed simultaneously, crops little line-spacing difficulty, and sowing different crops need to adjust seeder, affect work efficiency.
Thus, the problem being individually present based on above-mentioned fertilizer applicator, seeder, and also utilization rate of equipment and installations is relatively low, needs more
Practical, efficiency high, reduce cost can the agricultural machines of multi-purpose machine, to meet substantial amounts of fertilising, sowing demand.
Summary of the invention
The object of the invention is just to provide a kind of sowing and the multi-functional planting machine of Pneumatic type of the dual-use that applies fertilizer, and employing is many
The corresponding multiple separated material loculuses of individual refuse rotor, by blower fan to the pressure blowing of separated material loculus, by grain seed or fertilizer in separated material loculus
Quickly discharge along multiple delivery hoses, sow, the density that applies fertilizer is adjustable, sows fabric width adjustable, reduce cost, improve efficiency, can fit
Should various rotary cultivators, seeding device.
The technical solution used in the present invention: a kind of multi-functional planting machine of Pneumatic type, arranges hopper including on pedestal, pedestal,
It is characterized in that: described pedestal is arranged over charging aperture, on described charging aperture install hopper, below described pedestal uniform arrange many
Individual delivery hose;It is provided with blower fan plate on the upside of described pedestal, described blower fan plate is provided with blower fan;Described pedestal both sides are provided with
Side plate, described pedestal air channel installed below shrouding forms sealing air flue;
It is provided with concentration refuse rotor below described charging aperture, described concentration refuse rotor has multiple sheave and refuse rotor sheet and successively
Being staggered installation of in rotating shaft, described rotating shaft two ends are arranged on side plate;Concentration separated material it is provided with little below described concentration refuse rotor
Chamber, described concentration separated material loculus is arranged on pedestal, and described concentration separated material loculus is multiple separated material loculuses arranged side by side, and described separated material is little
Arranging discharging opening below chamber, each discharging opening described connects a delivery hose, and described delivery hose connects dispenser;Described pedestal
Outside is installed actuator drives and is concentrated refuse rotor;
Described rotating shaft could be arranged to square shaft, and described rotating shaft two ends are separately mounted on ball bearing and bearing block, described bearing block
It is arranged on side plate.
Described sheave is the tooth bar being axially evenly equipped with projection in circular wheel, has one between described each adjacent refuse rotor sheet
Sheave, described sheave forms uniform hopper with adjacent two refuse rotor sheets.
Two blower fans are at least installed on described blower fan plate.
Discharge regulating gate is installed on the downside of described charging aperture.
Described dispenser can arrange multiple and scalable and broadcast sowing fabric width.
The beneficial effects of the present invention is:
1, planting machine of the present invention coordinates frame and rotary cultivator to share the trifilar suspension of tractor, need not be arranged on rotary cultivator or sowing
On machine, also can be arranged separately on trifilar suspension use, therefore, improve the suitability of planting machine significantly.
2, due to the fact that employing is concentrated refuse rotor and concentrates separated material loculus, grain seed hopper conveying come in or fertilizer
Expect to disperse conveying to many places at one, the volume of planting machine can be reduced, need not accomplish, with an equal amount of width of rotary cultivator, to subtract
Little equipment volume and weight.
3, planting machine of the present invention uses high pressure positive blower to deliver to concentrate refuse rotor and concentration by air channel inner chamber by compressed gas
Separated material loculus, in sealing air flue, uses and concentrates separated material loculus to connect row's delivery hose, can on-demand regulation sowing, fertilising fabric width
And installation site, granule materials lands not against deadweight, thus limits the installation site sowing fabric width and flexible pipe, and standard is broadcasted sowing in sowing
The most uniformly, make mu spread precision and improve, reduce seed or fertilizer waste and the environmental pollution thereby resulted in.
4, planting machine of the present invention uses blower fan air conveying air channel shrouding, grain seed or fertilizer by concentrating separated material loculus
Dispersion is delivered to delivery hose, makes grain seed or fertilizer form mixture with compressed air, has moved past outstanding in flexible pipe
Floating speed, is difficult to stick and block pipeline;At flexible pipe outlet collocation widespread device, granulated fertilizer high-speed impact, on widespread device, is sent out
Life rebounds, and scattering is come, and uniformly falls on field, implements uniformly to sow, apply fertilizer, it is possible to increase utilization of materials, saves into
This input.
5, the multi-functional planting machine of Pneumatic type of the present invention is in fertilising, sowing one, can be not only used for fertilising, sows compound fertilizer, also
Can be used for multiple granular sow, sow crop seeds, such as Semen Tritici aestivi, grass seed, mustard, forage Secale cereale, feedstuff Radix Raphani, feedstuff
Brassica campestris L, Semen Pisi sativi etc., only need to change the refuse rotor of correspondence, it is achieved that a tractor serves several purposes, reduce farming cost and put into, and change letter
Folk prescription just, is directly installed on seeder during as fertilizer applicator, makes seeder achieve the function of ferti-seeding;It is arranged on wholely
On machine, it is achieved the function of site preparation and fertilization;It is arranged on stubble cleaner, it is achieved the function of stubble-cleaning site preparation and fertilization.
