Description
One, technical field
The said circumferential line of rabbet joint air-suction seed metering device of the utility model relates to the critical component of sower, belongs to agricultural mechanical field.
Two, background technology
Seeding unit is the critical component on sower, and its service behaviour directly affects the operation quality of whole sower.The at present domestic development of the seeding unit to frangible crops of granule such as millets is also in reduced levels, in seeding process, because easily causing, the problems such as the structure of seeding unit, material fill kind not exclusively, seeding is not thorough, seeding unit stops up or seed is rolled, the problems such as pulverizing, can not meet the technical requirement of fine grain crop precision drilling preferably; In addition, domestic air-suction seed metering device adopts aspiration disk structure more, and sealing effectiveness is bad, and because of easily stifled reason, is difficult to realize the sowing of small-sized seed.Therefore a kind of circumferential line of rabbet joint air-suction seed metering device that overcomes above-mentioned defect of the utility model design.
Three, summary of the invention
The utility model is for above problem, provide a kind of simple in structure, seeding thoroughly, not susceptible to plugging circumferential line of rabbet joint air-suction seed metering device, thereby this device is rotated and is realized even seeding by ground wheel drive.
The utility model solves the technical scheme that its technical problem adopts: a kind of axial slots air-suction seed metering device, its mainly by inhaling kind of annulus, left cap, right cap, mandrel, the slide block of dying, slider bracket, compression spring, a kind tank shell, surely plant sheet and form; Described suction kind annulus, left cap, right cap are arranged on described mandrel; The described slide block of dying is arranged on one end of described slider bracket; The other end of described slider bracket is arranged on described mandrel; Described compression spring with described in the slide block of dying be connected; The described slide block of dying, slider bracket and compression spring are all positioned at inhales kind of an annulus; Described suction kind annulus is placed in described kind of tank shell; The described sheet of surely planting is arranged on described kind of tank shell and can on kind of tank shell, moves left and right, and regulates and scrapes kind of a number like this.Described kind of tank shell turns round with land wheel, and mandrel maintains static.
Described mandrel hollow, can be used as air flue.
On the outer ring surface of described suction kind annulus, open the narrow line of rabbet joint, so just formed and inhaled kind of a groove, inhale kind of a groove and be one above and be uniformly distributed.
The described slide block of dying is formed and is closely cooperated by compression spring and described suction kind annulus inner side, plays the effect of the seeding of dying.
The beneficial effects of the utility model are: air chamber sealing performance is good, can reduce the energy consumption of blower fan; Seed number per is adjustable, adapts to different agriculture requirements; Seeding unit and kind case integral structure, compact conformation effectively reduces the height of charging seed; Seeding unit fills kind completely, and seeding is reliable, guarantee crop field planting, determine strain, realize the effect of reduction labour intensity.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: mandrel-1, plant tank shell-2, left cap-3, inhale kind of annulus-4, slider bracket-5, compression spring-6, slide block-7 of dying, spring pedestal-8, right cap-9, inhale kind of groove-10, gathering sill-11, surely plant sheet-12.
Five, embodiment
The utility model has solved seeding apparatus of seeder seeding difficulty, susceptible to plugging problem, provides a kind of simple in structure, the circumferential line of rabbet joint air-suction seed metering device that seeding is effective.
The utility model mainly by mandrel-1, plant tank shell-2, left cap-3, inhale kind of annulus-4, slider bracket-5, compression spring-6, slide block-7 of dying, spring pedestal-8, right cap-9, surely plant sheet-12 and form; Suction kind of an annulus 4, left cap 3, right cap 9 are arranged on mandrel 1; The slide block 7 of dying is arranged on one end of slider bracket 5; The other end of slider bracket 5 is arranged on mandrel 1; Compression spring 6 is connected with the slide block 7 of dying; Die slide block 7, slider bracket 5 and compression spring 6 is all positioned at and inhales kind of an annulus 4; Inhaling kind of an annulus 4 is placed in kind of tank shell 2; Surely plant sheet 12 and be arranged on kind of tank shell 2 and can on kind of tank shell 2, along gathering sill 11, move left and right, regulate and scrape kind of a number like this; Inhale kind of annulus 4 with land wheel running, mandrel 1 maintains static, and mandrel 1 hollow, can be used as air flue.
Inhale on the outer ring surface of kind of annulus 4 and open the narrow line of rabbet joint, so just formed and inhaled kind of a groove 10, inhale kind of a groove 10 and be one above and be uniformly distributed.
