Abstract

Disclosed is a seed metering device, which comprises a seed metering chamber, sowing wheels and seed clearing wheels. Wherein, the seed metering chamber comprises four chambers, a sowing wheel provided with a sowing hole is arranged in every chamber; hole diameters and hole distances of the sowing holes on every wheel are different. The four sowing wheels are arranged on one transmission shaft. The seed clearing wheels are arranged in every chamber arranged at front upper part of the transmission shaft; the corresponding sowing wheels and the seed clearing wheels are cooperated with each other.

Description

Seeding unit

Technical field

The utility model is put it briefly and is related to a kind of farm machinery, relates in particular to a kind of seeding unit.

Background technology

Present seeding unit generally has only three chambers, can only be used for sowing corn and soybean, if sow other crops, as beet, kidney bean, white melon seeds etc., must change seeding wheel, very trouble; The seed clearing wheel structure of existing in addition seeding unit is made of running roller and the hairbrush that is arranged on the running roller, and it easily falls hair, quick abrasion, thereby the life-span is short, just needs about 10 days to change, and very inconvenient, waste of manpower again, material resources and financial resources.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and long seeding unit of a kind of easy to use, life-span is provided.

The utility model seeding unit comprises seeding chamber, seeding wheel and seed clearing wheel.Wherein said seeding chamber comprises four chambers, and a seeding wheel with planting hole is housed in each chamber, and the aperture of the planting hole on each wheel is different with pitch-row.Four seeding wheels are installed on the same power transmission shaft.In each chamber of described power transmission shaft front upper place, be provided with seed clearing wheel.The work that cooperatively interacts of corresponding seeding wheel and seed clearing wheel.

The utility model seeding unit, the material of wherein said seed clearing wheel are Polyurethane or polytetrafluoroethylene (PTFE) or rubber, and the densely covered some end faces of its outer round surface are columnar projections or the semicircle hemisphere jut or the uniform serration of semicircle sphere.

The utility model seeding unit wherein also comprises seeds protecting plate.Described seeds protecting plate is installed in the front lower place of power transmission shaft, on it with the planting hole corresponding position be shaped as arc.

The advantage and the good effect of seeding unit described in the utility model are: it has four chambers, can be implemented in sowing crops not of the same race under the situation of not changing seeding wheel, as corn, soybean, beet, kidney bean, white melon seeds etc.Thereby the saving of labor, save time, reduce labour intensity; Its seed clearing wheel structure is that the densely covered some end faces of outer round surface are the columnar projections of semicircle sphere or Polyurethane running roller that is evenly equipped with serration or polytetrafluoroethylene (PTFE) running roller in addition, be about 5 times of existing seed clearing wheel its service life, thereby also prolonged the service life of seeding unit, in use reduce the number of times of changing seed clearing wheel simultaneously, reduce labor intensity, more convenient.

Other details of seeding unit described in the utility model and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.

Embodiment

The utility model seeding unit as depicted in figs. 1 and 2 comprises seeding chamber, seeding wheel 1 and seed clearing wheel 2, wherein the seeding chamber comprises four chambers, a seeding wheel 1 is housed in each chamber, has planting hole 3 on the seeding wheel 1, because crop seeds varies in size, so in order to sow different crops, each wheel is provided with the planting hole of different apertures and pitch-row.Four seeding wheels 1 are installed on the same power transmission shaft 4.In each chamber, power transmission shaft 4 front upper places (during sowing, the direction that seeding unit advances is the place ahead) is provided with 2, four seed clearing wheels of seed clearing wheel and is installed on the same power transmission shaft 8.Power transmission shaft 4 is a driving shaft, and it passes to power transmission shaft 8 by the sprocket wheel link chain mechanism with power.Seeding wheel and seed clearing wheel in the chamber fit tightly, and work cooperatively interacts.In the front lower place of power transmission shaft 4 seeds protecting plate 5 is installed.

By Fig. 3 and Fig. 4 as can be seen, with the arc that is shaped as of planting hole 3 corresponding positions, this kind shape helps reducing seed-cracking rate on the seeds protecting plate 5.

Referring to Fig. 5, Fig. 6, Fig. 7 and Fig. 8.The seed clearing wheel of the utility model seeding unit is made by the Polyurethane material, and this material is neither too hard, nor too soft, and the life-span is long, generally can sow two season crops.The material of seed clearing wheel also can be polytetrafluoroethylene (PTFE) or rubber.Outer round surface at seed clearing wheel 2 is densely covered with columnar projections 7 (see figure 7)s that end face is the semicircle sphere, its outer round surface also can be evenly equipped with serration 6 (see figure 5)s or semicircle hemisphere jut (not shown), this end face is that the columnar projections 7 of semicircle sphere or serration 6 or semicircle sphere are raised with the seeds that are beneficial to being retained in the planting hole 3 and clean out, use this seed clearing wheel, can save and plant plate or seed-clearing comb clearly, make that the structure of seeding unit is simplified.

Seeding unit described in the utility model is installed on the tractor with small four wheels matched farm tool,, drives the power transmission shaft 8 of seed clearing wheels 2 again by sprocket wheel link chain mechanism 10, just can sow by the power transmission shaft 4 of land wheel or main car bull wheel drive seeding wheel 1.During sowing, the chamber in four chambeies is connected grain tube, the seed that is positioned at planting hole 3 by clear wheel 2, is broadcast in the ground through seeds protecting plate 5 under the rotary action of seeding wheel 1 again, is isolated in the sowing chamber and be positioned at planting hole 3 outer seeds by seed clearing wheel 2.When needs are sowed different crops, only need the conversion grain tube to get final product, and needn't change seeding wheel, thereby make speed of drilling accelerate, avoided unnecessary work, reach saving of work and time, raise labour efficiency.
