Fixed-quantity and equal-length rice transplanter for rice planting

Abstract

The invention relates to the technical field of agricultural machinery and discloses a fixed-quantity and equal-length rice transplanter for rice planting. The rice transplanter comprises a fixing rodand is characterized in that a first connecting rod movably sleeve each of two ends of the fixing rod, a second connecting rod is rotatably connected to one end of each first connecting rod, a thirdconnecting rod is rotatably connected to the middle of each second connecting rod, a rotary shaft is fixedly nested into one ends of the third connecting rods, a transmission gear fixedly sleeve eachrotary shaft, and a length adjusting device is rotatably connected to the other end of each second connecting rod. The rice transplanter has the advantages that by the coordination of adjusting screwsand clamping jaws, the two clamping jaws can be driven to move towards or away from each other by rotating the adjusting screws so as to regulate the distance between the two clamping jaws, corresponding adjusting can be performed conveniently according to seedlings of different varieties, and the situation that seedlings are clamped inside the clamping jaws or the seedlings fall off can be prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a quantitative equal-length rice transplanter for rice planting. Background technique [0002] Rice transplanter is a kind of agricultural machinery for implanting rice seedlings into the paddy field. When planting, first take out several rice seedlings from the seedbed with mechanical claws and insert them into the soil in the field. In order to keep the angle between the seedbed and the ground at right angles, the machine When the front end of the claw moves, it must adopt an elliptical action curve. The action is completed by the planetary mechanism of the rotating or deformed gear. The forward engine can drive these action machines at the same time. The rice transplanter must have non-slip wheels when moving on the soil. And the floating row design, if the seedlings are inserted into pieces, the rice seedlings are taken out from a specific seedling box, and the...

AI Technical Summary

Problems solved by technology

[0003] The jaws of existing rice transplanters are all integrally formed, and the width of the clamping groove inside the jaws is fixed, but the sizes of different varieties of rice seedlings are different, and the thickness and height are also different. If the rice seedlings are thick, it will easily cause The seedlings are stuck inside the jaws. If the seedlings are too thin, the jaws may not be able to grip the seedlings normally, causing the seedlings to fall off.
