Description
Technical field
The invention belongs to agricultural seeding machine technical field, be specifically related to a kind of precision planter automatic ration and add kind of a device.
Background technology
Sowing is the important step in agricultural production process, and along with the high speed development of economic society, the continuous progress of agricultural science and technology, the enforcement of precision agriculture, has higher requirement to seeding quality.Sower is the Main Means realizing mechanization precise sowing technology, and the quality of its performance directly affects upgrowth situation and the output of seeding quality and crops.The precise seeder for raising that the present invention matches is a kind of aspiration vibrating precise sower, it can overcome the many shortcomings of mechanical type seeding apparatus, seed physical dimension is required not tight, easily realize simple grain program request, there is the advantages such as operating speed is high, seed damage ratio is little.Aspiration vibrating precise sower is in seeding process, strict requirement is had to the seed layer thickness in kind of dish, seed layer thickness must remain in an exact extension, under effect of vibration, " boiling " motion state is realized if seed group can not be made in scope, some sucker hole will be caused to inhale cause sowing hole less than seed, this adds kind of device to make sower once adding within the scope of the kind layer thickness that the seed in kind of the cycle in kind dish remains on required by sower with regard to needing a kind of automatic ration, the seed in sower vibration seed tray is made to keep " boiling " motion state, ensure the precise sowing requirement of aspiration vibrating precise sower.
The present invention is that a kind of precision planter automatic ration adds kind of a device; automatic ration can be realized and accurately add kind; adding kind of amount can quantitative setting as required; and reasonable in design is furnished with band rubber bending plate and cavernous body protective layer; low to seed degree of injury; once adding to plant to make the sower working time longer, provides condition for realizing air suction vibration disc type field nursery precise sowing.
Summary of the invention
The object of the invention is to provide a kind of device realizing automatic ration and to add kind, meet seed layer thickness in precise sowing machine dish and remain on one and accurately inhale in kind of the scope required, with the motion state that ensures that seed is in all the time in seeding process " boiling ".
Realizing technical scheme of the present invention is: a kind of precision planter automatic ration adds kind of a device and comprises controller, stand, stepper motor, sprocket wheel one, chain, quantitatively adds kind of a hopper, sprocket wheel two.Controller is arranged on stand, stand is arranged on seeder dish and adds kind of a position, stepper motor and quantitatively add kind of a hopper and be bolted on stand, quantitatively add output shaft axis and the stepper motor output shaft axis being parallel of kind of hopper, sprocket wheel one is arranged on stepper motor output shaft, sprocket wheel two is arranged on and quantitatively adds on kind of hopper output shaft, and chain, sprocket wheel one, sprocket wheel two coordinate formation Chain conveyer.Quantitatively add kind of hopper and comprise hopper housing, hopper output shaft, the outer groove-wheel of recessing, bearing cap, bearing block, bearing, band rubber bending plate, cavernous body.Hopper output shaft is connected on hopper housing by bearing cap, bearing block, bearing, and the outer groove-wheel of recessing is connected on hopper output shaft by key, the dead in line of the axis of hopper output shaft and the outer groove-wheel of recessing.Band rubber bending plate is bolted in hopper shell inner surface, and cavernous body is close to the outer groove-wheel periphery of band rubber bending plate and recessing, and rubber sticks in three sections of bending steel plate upper surfaces by all-purpose adhesive.When seed layer thickness is in below low sensors, Single-chip Controlling stepper motor moves, driven by Chain conveyer and quantitatively add kind of a hopper output shaft rotation, outer groove-wheel has groove, seed in groove falls into kind of a dish, and when seed layer thickness arrives high position sensor, Single-chip Controlling stepper motor motion stopping adds kind, realize automatic ration and add kind, meet the seed number of plies in precise sowing machine dish and remain in accurate suction kind of a scope required.
The invention has the advantages that:
(1) can realize automatic ration and add kind, adding kind of amount can need to arrange according to suction kind, improves the automaticity of sower.
(2) and reasonable in design be furnished with band rubber bending plate and have cavernous body protective layer, low to seed degree of injury, once add and kind the sower working time can be made longer, sowing efficiency is improved greatly.
(3) to have structure simple for this device, is easy to control, and processing cost is low and to add kind of precision higher.
Accompanying drawing explanation
