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 capable close planting type rice transplanting machine of paddy rice width that is used for.
Background technology
It is that 24cm, wide row are the capable rice transplanters of width of 30cm that present hand-held and high-speed rice seedling planter such as have at the 30cm of line-spacing and 24cm rice transplanter and narrow row.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 not owing to there is suitable rice transplanter, substantially be transplanting rice seedling by hand,, press for the close planting type rice transplanting machine of the suitable hybrid rice production of hybrid seeds along with the rural laborer shifts and the rise of labour's wage cost.The key that adapts to hybrid rice production of hybrid seeds machine transplanting of rice seedling 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 capable saddle type rice transplanter of width that proposes to know clearly.In order to reduce the complexity of rice transplanter, adopt the blanket shape seedling of a seedling-containging disc by the seedling taking of two seedling pawls in the design, but, two rice shoots of wide line space are got slotting mechanism and are connected on the same transmission case, make two row rice shoots of rice transplanter limit row that a transmission case that has only two seedling pawls need be set specially, in fact increased the complexity of machine.If this design philosophy is used for the hand transplanting machine of dense planting, to increase the transmission mechanism complexity of hand transplanting machine too.Also the someone has proposed to adopt the width capable 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 just is 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 Lou seedling phenomenon.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of capable rice transplanter of width that is used 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 capable dense planting hand transplanting machine of width 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 helix spindle nut, seedling case connecting rod, seedling case double helix axle, space bar, seedling-containging disc, side plate, seedling door, 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 helix axle is a double helix axle with uniform pitch, be rotary with the double helix spindle nut on it, double helix spindle nut, seedling case connecting rod are fixedlyed connected with the seedling case, and the seedling case places on the slideway, and slideway is fixed on the bottom of handrail, have the seedling door on it, the number of seedling door is all corresponding with the seedling pawl with the 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 links to each other with crank with rocking bar.Jackshaft sprocket wheel on the jackshaft links to each other with several seedling pawl crank axles by the crank axle sprocket wheel, and seedling pawl and rocking bar, crank, seedling box mover transmission case constitute a crank and rocker mechanism.Connect two seedling pawls simultaneously on the seedling pawl crank axle.The frame two ends link to each other with the seedling box mover transmission case with gearbox respectively, and handrail links to each other with the seedling box mover transmission case.Engine is positioned at the front end of whole device, and engine links to each other with gearbox by belt wheel, and gearbox links to each other with left driving wheel by the left driving wheel chain cover, and gearbox links to each other with right driving wheel by right driving wheel chain cover.
Further, described two seedling pawls that are connected on the same seedling pawl crank axle constitute 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 the different seedling pawl crank axles constitute 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
3Be narrow row line-spacing K
1Twice, and have more 2～5mm.
The present invention compares with background technology, and the beneficial effect that has is:
1, because operating personnel's left and right pin is to walk respectively in the wide row of narrow row and arranged on left and right sides in the middle of machine, single pin is walked to reduce the capable width of walking.So, can realize the capable rice transplanting operation of the close planting type width bigger than present 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 and leaks seedling.
3, the motion of the rice transplanting seedling pawl of per two narrow rows is to be driven by same seedling pawl crank axle, can significantly reduce the complexity of rice transplanting mechanism transmission system.
