Description

Sieve formula sower

One. technical field

Sieve formula sower belongs to seeding machinery field.

Two. background technology

Seeding machinery in the market mainly contains pneumatic type, grooved pulley type, and nest eye is wheeled, electromagnetic type etc.Pneumatic type complex structure, efficiency is low, and fault is many; Grooved pulley type, nest eye wheeled wound kind, card seed, the amount of broadcasting regulates inconvenient; Electromagnetic type complex structure.

Three. summary of the invention

There is provided a kind of structure simple, the machine of the sieve formula that efficiency is high, its concrete structure and principle as follows:

Sieve formula sower by for kind of device, a seeding apparatus, broadcast quantity regulating device, drive unit and running gear and form; Seed-storage box, seed output pipe, buoyancy aid, pole, choked flow dish, cone, gag lever post, extension spring is comprised for kind of a device; Seeding apparatus involving vibrations sieve, sieve plate, sieve aperture, fork; Broadcast quantity regulating device and comprise the amount of broadcasting adjustable plate, nut, T-shaped screw rod, fork-shaped spanner, sliding sleeve and chute; Drive unit comprises motor, gear one, gear two, gear three, gear four, chain one, chain two, bearing one, bearing two, crankshaft-and-connecting-rod; Running gear comprises driving wheel, driving shaft, road wheel and frame.

Seed-storage box is fixed in frame, and cylindrical shape seed output pipe is arranged at bottom; Prisoner's body is the hollow body made with light material, bottom is plane, and top is convex surface, convex surface top is upwards fixed together with pole, choked flow dish, cone, position-limited needle successively, is suspended on seed output pipe by extension spring, position-limited needle stretches in seed output pipe, has gap between the conical surface and seed output pipe; Used by oscillating screen fork is suspended on seed-storage box, and vibratory sieve central space is outstanding buoyancy aid, and bottom is connected sieve plate, and sieve plate has sieve aperture, and the size and shape of sieve aperture is similar to seed, more bigger than seed, and below sieve plate, there is slot at two ends; The amount of broadcasting adjustable plate is inserted into below sieve plate from slot, and sieve plate edge is connected nut, and T-shaped screw rod one end and vibratory sieve are hinged, and centre is screwed in nut, and the other end is arranged in the prong of fork-shaped spanner, and fork-shaped spanner inserts in sliding sleeve, and sliding sleeve is connected in frame; Motor is connected in frame, and output shaft is connected gear one and gear two, and gear one and gear two are connected with gear four with gear three with chain two with chain one respectively; Gear three and bent axle are connected, and bent axle is connected in frame through bearing one, and one end of connecting rod is connected with bent axle through bearing two, and the other end is connected with fork; Gear four and driving shaft are connected, and driving shaft and driving wheel are connected, and driving shaft is connected in frame through bearing, and road wheel is connected in frame through bearing.

The course of work: starter motor 5, vibratory sieve 2 swings, the component vibration causing buoyancy aid 3 and be attached thereto, because good fluidity during solid vibration, seed flows to choked flow dish 32 through the gap between cone 33 surface and seed output pipe 11, then drop on the convex surface of buoyancy aid 3, then tumble in vibratory sieve, broadcast from sieve aperture 22, when in vibratory sieve, rise in seed face, buoyancy aid floats, make gap smaller between cone 33 and seed output pipe 11, reduce for kind of speed, when seed face in vibratory sieve declines, buoyancy aid declines thereupon, between cone and seed output pipe, gap becomes large, increase for kind of speed.Due to the pulling force effect of extension spring 35, make buoyancy aid be in " zero-g " state, buoyancy aid is up and down sensitiveer under seed buoyancy.This seed that just can accurately control in vibratory sieve is how many, ensures the uniformity of sowing.If operation stopping, vibratory sieve stops vibration, and buoyancy aid and the parts stopping vibration being attached thereto, because not having the solids flowability of vibration poor, seed can be piled up and block seed output pipe on the planar annular of choked flow dish 32, stops for planting.Avoiding problems the defect that cannot stop when stopping operation supplying to plant.The position-limited needle of pyramid tip is very long, is positioned at seed output pipe all the time, and its effect one is that stir seed in seed output pipe, prevent seed blocking pipe, two is after preventing cone from moving down when vibrating, then on when moving, can not enter in seed output pipe.

The amount of broadcasting adjustable plate 4 can block sieve aperture 22, rotates fork-shaped spanner 43, can change the length that T-shaped screw rod 42 is screwed into nut 41, thus promotes the amount of broadcasting adjustable plate, and effective screen number is changed, thus regulates the amount of broadcasting.Because T-shaped screw rod can slide in the prong of fork-shaped spanner, can descend the adjustment amount of broadcasting in working order, regulate the amount of broadcasting easy to operate, this is that other sower is too late.

Because using same motor driving crank linkage, vibratory sieve being sowed, driving running gear, sower is walked, this just can ensure that shaker vibration number of times is constant with sowing distance proportion, thus ensures that sowing evenly.

Because this sower relies on vibration seeding, the seed (as rape) of good fluidity can be adapted to, also can adapt to the seed (as paddy rice) of poor fluidity.

This sower also can be sowed by Manual-pushing.
