Abstract
The invention discloses a cross-row traveling wide-narrow row close planting hand-held rice transplanter, comprising an engine, a ground traveling imitation mechanism, a driving wheel traveling system, a rice transplanting mechanism, a reciprocating mechanism of a rice case, and a hand-held operation system. The distance between the transplanting claws of the rice transplanter is arranged according to the width interval of a wide row and a narrow row. The two transplanting claws in the middle of the rice transplanter form a middle narrow row, a piece of blanket-shape seedlings on the rice case is taken by two crank rocker-type rice transplanting mechanisms at the same time to form the close planted wide-narrow row transplanting, and the crankshafts of the two crank rocker-type rice transplanting mechanisms are connected together. An operator can walk on the two wide rows adjacent to the narrow row in the middle. Due to that the left foot and the right foot of the operator step on the wide rows at the left side and the right side of the middle narrow row, and the traveling by one foot can reduce the width of the traveling row, therefore the close planting wide-narrow row transplanting operation with the larger transplanting density than that of the existing hand-held rice transplanters can be realized.
Description
Technical field
The present invention relates to a kind of rice planting machine, especially, relate to a kind of for wide-and narrow-row rice close planting type rice transplanting machine.
Background technology
Current hand-held and high-speed rice seedling planter such as have at 30cm and the 24cm rice transplanter of line-spacing, and narrow row is that 24cm, wide row are the wide-and narrow-row rice transplanters of 30cm.The seeding row spacing of these rice transplanting machine transplanting of rice is wide, and the clump number density of unit are is too low, can not adapt to the requirement of the male sterile line machine transplanting of rice in the hybrid rice production of hybrid seeds.China's hybrid rice area accounts for the paddy rice gross area more than 60 percent, the hybrid rice production of hybrid seeds is owing to there is no suitable rice transplanter, substantially be transplanting rice seedling by hand, along with the rural laborer shifts and the rise of labour's wage cost, in the urgent need to the close planting type rice transplanting machine of the suitable hybrid rice production of hybrid seeds.The key that adapts to hybrid rice production of hybrid seeds transplanting be machine transplanting of rice line-spacing from original 30cm or 24cm, design machine transplanting of rice line-spacing is that 15cm is to 20cm.
The operating personnel of existing hand transplanting machine are the centres of walking at the rice transplanter middle two rows, and middle line space is 30cm.For this reason, have no idea to reduce middle line space.
Someone wide-and narrow-row saddle type rice transplanter that proposes to know clearly.In order to reduce the complexity of rice transplanter, in design, adopt the blanket shape seedling of a seedling-containging disc by the seedling taking of two seedling pawls, but, two rice shoots of wide line space are got slotting mechanism and are connected on same transmission case, make two row rice shoots of rice transplanter limit row that a transmission case that only has two seedling pawls need to be set specially, in fact increased the complexity of machine.If this design philosophy is used for to the hand transplanting machine of dense planting, to increase too the complicated mechanism degree of hand transplanting machine.Also someone has proposed to adopt the wide-and narrow-row rice transplanter of the blanket shape seedling of a seedling-containging disc by the seedling taking of two seedling pawls, but, the width of seedling-containging disc is just the twice of two narrow row seedling pawl spacings, and it is not smooth that this design can cause blanket shape seedling to glide along seedling-containging disc, easily causes the miss in seedling setting phenomenon.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of rice transplanter of the wide-and narrow-row for the paddy rice dense planting is provided.
In order to achieve the above object, the technical solution used in the present invention is: a kind of wide-narrow row close planting hand transplanting machine of inter-bank walking comprises side kickboard, middle kickboard, engine, gearbox, left driving wheel sprocket cassette, right driving wheel sprocket cassette, left driving wheel, right driving wheel, frame, seedling box mover transmission case, seedling case, handrail, slideway, double-screw shaft nut, seedling case connecting rod, seedling case double-screw shaft, space bar, seedling-containging disc, side plate, seedling setting gate, seedling pawl, rocking bar, crank, seedling pawl crank axle, crank axle sprocket wheel, jackshaft sprocket wheel, jackshaft.Wherein, described side kickboard and middle kickboard are positioned at the bottom of whole device, seedling case double-screw shaft is a double-screw shaft with uniform pitch, be rotary with the double-screw shaft nut on it, double-screw shaft nut, seedling case connecting rod are fixedly connected with the seedling case, and the seedling case is placed on slideway, and slideway is fixed on the bottom of handrail, have seedling setting gate on it, the number of seedling setting gate is all corresponding with the seedling pawl with position.The seedling case is formed by fixedly connecting by several seedling-containging discs, space bar and side plate, and space bar and side plate are higher than seedling-containging disc, and the seedling pawl is connected with crank with rocking bar.Jackshaft sprocket wheel on jackshaft is connected with several seedling pawl crank axles by the crank axle sprocket wheel, and seedling pawl and rocking bar, crank, seedling box mover transmission case form a crank and rocker mechanism.Connect two seedling pawls on a seedling pawl crank axle simultaneously.The frame two ends are connected with the seedling box mover transmission case with gearbox respectively, and handrail is connected with the seedling box mover transmission case.Engine is positioned at the front end of whole device, and engine is connected with gearbox by belt wheel, and gearbox is connected with left driving wheel by the left driving wheel chain cover, and gearbox is connected with right driving wheel by right driving wheel chain cover.
Further, described two seedling pawls that are connected on same seedling pawl crank axle form narrow row, and these two seedling pawls are in same seedling-containging disc seedling taking, and adjacent two the seedling pawls that are connected on different seedling pawl crank axles form wide row.Described narrow row line-spacing is K
1=12～18cm, wide every trade distance is K
2=24～36cm, the width K of seedling-containging disc 20
3narrow row line-spacing K
1twice, and have more 2～5mm.
The present invention compares with background technology, and the beneficial effect had is:
1, the left and right pin due to operating personnel is to walk respectively in the wide row of narrow row arranged on left and right sides in the middle of machine, and single pin is walked the width that can reduce the walking row.So, can realize the close planting type wide-and narrow-row rice transplanting operation larger than current hand transplanting machine density of transplants.
2, the blanket shape seedling that adopts a seedling-containging disc is by the seedling taking of two seedling pawls, and 2～5mm more than the twice of the width narrow row width of seedling-containging disc can be so that the width of seedling-containging disc be slightly larger than the width of blanket shape seedling, eliminates the blanket shape seedling disadvantageous problem that descends, and reduces miss in seedling setting.
3, the motion of the rice transplanting seedling pawl of every two narrow rows is to be driven by same seedling pawl crank axle, can greatly reduce the complexity of rice transplanting mechanism transmission system.
