Abstract

The invention relates to a wide- and narrow-row rice transplanting mechanism and belongs to agricultural machinery. Two driving shafts of a universal transmission device are respectively connected with the left end and the right end of a chain wheel shaft of a chain box assembly; the left side wall and the right side wall of a box body of a chain box assembly are respectively and sequentially provided with a bearing and a sealed ring; two driven shafts of the universal transmission device are respectively inserted into the bearing and the sealed ring which are arranged on the left side wall and the right side wall of the box body; the two driven shafts of the universal transmission device are in inclined arrangement on a plane perpendicular to an axial line and have low external ends and high internal ends; the internal ends of the driven shafts of the universal transmission device are hinged with the driving shafts of the universal transmission device by adopting a cross shaft; transplanting arm assemblies of a left side and a right side are arranged at a left outer end and a right outer end of the chain box assembly; the external ends of the driven shafts of the universal transmission device are respectively and fixedly connected with actuating arms of the transplanting arm assemblies of the left side and the right side; and the transplanting arm assemblies of the left side and the right side are in a V-shaped inclined arrangement in a vertical direction integrally. The mechanism has the advantages of simple structure, light weight, low manufacturing cost, reliable operation and low fault rate.

Description

The capable rice transplanting mechanism of paddy rice width

Technical field

The invention belongs to agricultural machinery, relates generally to the rice transplanting mechanism on the rice transplanting facility.

Background technology

The capable rice transplanting of width is meant that the line space of rice transplanting carries out one wide one narrow planting patterns, this planting patterns is utilized the volume increase principle of crop limit advantage, by adjusting the line space of rice transplanting, improve ventilation, light transmittance between plant, alleviate disease, increase leaf area index, prolong leaf longevity, quicken dry-matter accumulation, thereby reach the purpose of good quality and high output, cost-saving synergistic.Transplanting mechanism is to realize seedling taking on the rice transplanter, implant Tanaka, make the parts of rice shoot succeeding planting.In existing disclosed rice transplanter transplanting mechanism, its transmission case all adopts chain drive, left and right two transplanting mechanisms on the rice transplanter all adopt and parallel with direction of advance and the structure configuration on ground perpendicular to the ground, transplant arm on the transplanting mechanism also can only be done and be parallel to direction of advance and perpendicular to the plane motion on ground, under seedling fetching hole is equally spaced prerequisite, the capable rice shoot of width that the rice transplanting position can not form agriculture requirement distributes, and has influenced applying of width capable rice transplanting new agricultural process method.For addressing the above problem, the capable transplanting mechanism scheme of the width of a kind of single shaft or twin shaft all-gear drive structure proposes, this structure is complex structure not only, the manufacturing cost height, weight is big, installs and uses inconvenience, and only be applicable on the high-speed rice seedling planter that is fitted in two seedling pins and use, the scope of application is little, to used recoverable amount hugely the chain drive rice transplanter can't change equippedly, cause waste.

Summary of the invention

The purpose of the invention is exactly the problem that exists at above-mentioned prior art, actual needs in conjunction with the capable rice transplanting of agricultural production paddy rice width, design provides a kind of paddy rice width capable rice transplanting mechanism, utilizing on the existing chain drive case basic structure basis, reaching satisfied, adapt to and realize the capable operation agriculture requirement of rice transplanting width, reduce that facility are changed, reduced manufacturing cost, prolong facility service time, the purpose of the waste of reducing the loss.

The purpose of the invention is achieved in that the capable rice transplanting mechanism of paddy rice width comprises transplant arm assembly and chain box assembly, two universal driver driving shafts respectively with the sprocket shaft left side of chain box assembly, right-hand end is affixed, casing left side at the chain box assembly, equipped successively from the inside to the outside bearing and sealing ring on the right side wall, two universal driver driven axles are inserted into a casing left side respectively, in the bearing and sealing ring hole that is equipped with on the right side wall, on the axial line vertical plane of universal driver driven axle, it is low that two universal driver driven axles all are the outer end, inner high skewed configuration, the inner end of two universal driver driven axles adopts cross axle to be hinged with two universal driver driving shafts respectively, on a chain box assembly left side, the right outside is a configuration left side respectively, the transplant arm assembly on right side, the outer end of two universal driver driven axles respectively with a left side, the actuating arm of the transplant arm assembly on right side is affixed, a left side, the transplant arm assembly on right side integral body in vertical direction is the skewed configuration of V-shape.

The invention is by setting up a left side in the chain box assembly of existing chain drive, the right side vertical direction is the universal driver and a left side that knuckle is provided with, the V-shaped equipped transplant arm assembly combining structure of right side vertical direction, realized on the traditional water rice transplanter, finishing the capable rice transplanting job requirements of paddy rice width, satisfy and adapted to the operation needs of advanced agronomic technique, applying and improve rice crop output advanced agronomic technique, quality plays active promoting function, and this mechanism has simple in structure, overall weight is light, cheap for manufacturing cost, operation is reliable, width seedling rice transplanting quality is good, the characteristics that operational failure is few.
