Abstract
The utility model relates to a pin-gear type precision planter which is characterized in that a wheel body with a rubber belt can directly roll on the soil. The seeds can be pressed in the soil or the ground through a needle bar without a seeding height, and the pin-gear type precision planter has a high seeding accuracy. The pin-gear type precision planter can draw the high-speed work with the large, the middle and the small tractor, and the pin-gear type precision planter can be used with the animal labor farm implement or pushed by people. The pin-gear type precision planter can finely seed the corn and the soy, seed the paddy rice, the cotton, the beet and the sorghum in the hole type and can seed the wheat and the antique in the line type. The pin-gear type precision planter is composed of a wheel body, a rubber belt, a needle bar, a cam wheel and a spring.
Description
The utility model is a kind of pinwheel formula precision planter.
Present existing sower, pneumatic type manufacturing cost height, consumption of power be big, can not be supporting with animal-drawn farm implements; Mechanical type exists strict to the seed physical dimension, changes seed and need change shortcomings such as parts.Especially all kinds of sowers are all charged seed highly, after seed lands the variation of rolling take place, and have a strong impact on seeding accuracy, thereby little spacing in the rows high speed and precision are difficult to realization.
The finger push boat formula sower of the duck-beak type mulch film cotton planter that Xinjiang of China is produced and West Germany Bonn agrotechnique professor Bo Linman of institute research, these the two kinds height of not charging seed are that wheel body directly rolls on the face of land and seed directly is sowed at sower in the soil.But duck-beak type is better at the mulch film upper seeding wheel, directly the duckbilled clay is arranged and the shortcoming of broadcast leakage at the soil upper seeding wheel; Refer to push boat formula complex structure and be the pneumatic type seeding unit, be unfavorable for generally promoting.(seeing " West Germany's precision planter is investigated " literary composition that the Chinese agricultural machinery Zhang Dewen of institute writes).
The utility model purpose is, provides a kind of simple in structure, directly is sowed at seed in the soil or need not change parts and just can broadcast various seed on the ground, realizes high speed and precision, and can with the sower of the supporting or artificial hand push use of animal-drawn farm implements.
Content contrast description of drawings of the present utility model is as follows:
Two circular side panel 1 sandwich outer rings 3 and inner ring 4 constitute wheel bodys.The uniform several holes of going out in the edge of side plate 1 is being adorned two ends and is being made the quarter butt 11 of pin with iron wire 8 in the hole, be used for supporting and fixation adhesive tape 2.Circumference uniform distribution is made row or several apertures of the every row of plurality of rows on the inner ring 4.Row or several apertures of the every row of plurality of rows with inner ring 4 equal numbers are made in outer ring 3.Small-bore on the outer ring 3 axially outside in suppresses two grooves of symmetry to two gap that suppress symmetry.Also want the uniform macropore of some outside crimpings, the usefulness that in wheel body, passes in and out for seed of making on 3 circumference of outer ring.Shank 6 is installed in the aperture of inside and outside circle, is adorning spring 5 at an end of 4 li of inner rings, and an end of 3 li symmetry extrudes two projectioies in the outer ring, in order to transfer the cave apart from the time use.Main shaft 12 is installed with cam 7, is adorning little spring 9 and straight pin 10 in the cam 7, plays the effect of chaste tree tooth, and cam 7 can rotate with wheel body during in order to the wheel body reversing, prevents shank 6 bendings.Pull bar 13 is fixed on the two ends of main shaft 12.The wheel body excircle teases the adhesive tape of being made by gentle matter high-abrasive materials such as clamp rubber 2.Align with shank 6 on the adhesive tape 2 and make cross and stitch thoroughly, sew semicircle boss thoroughly, be beneficial to deposit a quantity of seeds around cross.A quarter butt 11 is compressed at the two ends of adhesive tape 2 respectively, and adhesive tape 2 two ends are stuck in side plate 1 oblique mouthful by quarter butt 11, makes the end of adhesive tape 2 can opening and closing, in order to the usefulness of dress kind and clear kind.
During work adhesive tape 2 one ends are raised, seed is packed in the wheel body, adhesive tape 2 is closed again, external force traction pull bar 13 advances, wheel body rolls on the face of land together with adhesive tape etc., and seed is before the boss that constantly charges into below wheel body under the effect of centrifugal force and gravity on the adhesive tape 2.The seed that shank 6 around cam 7 rotation, under cam 7 effects, makes the lower end of each shank 6 prick out the saturating seam of the cross from adhesive tape 2 in turn in the wheel body bottom with wheel body, deposit in before with boss is by in soil.Shank withdrawal automatically under spring 5 effects then, the cross on the adhesive tape 2 stitches auto-closing thoroughly.Sower constantly rolls, and seed just by a grain or a cave bunch planting on the ground.
Bar rotating spindle sowing time 12 moves after making cam 7 lower ends, and shank 6 is released seed at the wheel body rear portion, makes the seed can not be directly by in burying, and certain height of charging seed occurred, and seed can scatter and collapse out, and becomes drilling.
Outwards twitch shank 6 when adjusting at interval in the cave, makes to revolve behind the radially gap of projection by the aperture on the outer ring 3 on the shank 6 to turn 90 degrees, and projection is stuck in the aperture axial notch, and shank 6 is no longer withdrawn like this, is in off position.The wheel body cave number of broadcasting that rotates a circle equals the number of the shank 6 of not twitched.When idle shank needs work, can again it be revolved and turn 90 degrees, withdraw automatically at spring action lower needle bar 6, in running order, thus realize that the cave is apart from adjustment.
The adjustment of the bar amount of broadcasting sowing time also is to realize by the work number that changes shank 6.
The sowing of defective ejaculation amount is a new agricultural technology that economic benefit is huge, can reach a large amount of saving breedings and the purpose that increases substantially output.Promoting this technology must have high-quality, high efficiency sower to realize.The utility model is a kind of simple in structure, dependable performance, low price and has high target, high-precision sower, compares with existing sower to have bigger practical value.
Description of drawings: accompanying drawing is a pinwheel formula precision planter structure chart.
The 1-side plate, 2-adhesive tape, 3-outer ring, 4-inner ring, 5-spring, 6-shank, 7-cam, 8-iron wire, 9-little spring, 10-straight pin, 11-quarter butt, 12-main shaft, 13 pull bars.
The utility model both can adapt to the operation of large, medium and small tractor-drawn multirow high speed, also can wait animal-drawn farm implements supporting with plough, also can be used by artificial hand push, realized corn, Soybean and Other Crops The crop such as Precision Seeding, paddy rice, cotton, Chinese sorghum, beet bunch planting, take into account the drillings of the crops such as wheat, millet.
Its hanging beam, plough, soil covering implement etc. can be general with existing seeder, thus do not do description, direct seading rice and plough in the autumn on hang the combination sowing by cultivator and can omit plough and soil covering implement.
