Variable-row-spacing transplanting machine for rice pot seedlings

Abstract

A variable-row-spacing transplanting machine for rice pot seedlings comprises a seedling sending mechanism, a seedling taking mechanism, a seedling conveying mechanism and a transplanting mechanism, wherein the seedling sending mechanism is used for sending the rice pot seedlings to the position where the rice pot seedlings are to be clamped, and the rice pot seedlings are clamped by the seedling taking mechanism and then conveyed to the transplanting mechanism by the seedling conveying mechanism, so that variable-row-spacing transplantation of the rice pot seedlings is completed. Multiple seedling conveying barrels are arranged in the seedling conveying mechanism and have variable row spacing, so that variable-row-spacing transplantation is realized; meanwhile, the seedling conveying mechanism is combined with the seedling sending mechanism, the seedling taking mechanism and the transplanting mechanism, thus, a series of operations for transplanting the rice pot seedlings to fields are completed, one-to-one rice pot seedling grasping and inserting planting are effectively realized, the requirement for the height of the rice pot seedlings is not high, the row spacing is changed according to actual requirements, and the grain yield of China can be substantially increased.

Description

Technical field [0001] The invention relates to the technical field of agricultural and forestry machinery planting devices, in particular to a variable row spacing transplanter for rice bowl seedlings. Background technique [0002] In some rice-producing areas in my country, especially in the southern double-cropping rice-growing areas, row spacing transplanting of rice needs to be adapted to the transplanting of late rice, hybrid rice sparse planting, early rice dense planting or super rice small-row seed production. The row spacing of the existing rice transplanters in China is mainly fixed to 30cm wide. There are common defects in the southern double-cropping rice areas where the sun and rainfall are sufficient: for early rice with short growth period and relatively short plants, the planting density is sparse and often It is difficult to completely seal the rows at maturity, which leads to insufficient effective panicles, which not only wastes the field, is not conducive to ...

AI Technical Summary

Problems solved by technology

The row spacing of the existing rice transplanters in China is mainly fixed at 30cm wide, and there are common defects in the southern double-cropping rice areas with sufficient sunlight and rainfall: for early rice with a short growth period and relatively short plants, the planting density is sparse, often reaching When it is mature, it is difficult to completely close the row, which leads to insufficient effective panicle number, which not only wastes the field, is not conducive to the high yield of early rice, but also cannot give full play to the production potential of machine-transplanted rice, resulting in a relatively reduced yield; moreover, if the early rice is used with a small row spacing of 24cm, Late rice is transplanted with a large row-spacing 30cm transplanter, and there will be a waste of equipment resources for the same mu of land using two kinds of transplanters. The fixed-row-spacing rice transplanter cannot meet the actual needs of rice planting in my country, so it is urgent to adapt to the 24-30cm at the same time. row spacing rice seedling transplanter

[0003] At the same time, when farmers use mechanical transplanting, the requirements for seedling raising technology are too high, and the seedling raising process is easily restricted, and the water and fertilizer management are complicated and cumbersome; the control of seedling stage is not easy: if the seedling stage is too long, the seedling stem will be long and large, and it will be difficult to transport. Or when planting and grabbing, it is easy to break the seedlings or cause "bridge" phenomenon; if the seedling period is too short, the seedlings are tender and thin, and they are easy to pinch and bruise when planting. Both situations are easy to cause the seedlings to turn green after planting Long, the growth quality is not high, resulting in reduced yield
