Rice transplanter capable of automatically replanting seedlings

Abstract

The invention discloses a rice transplanter capable of automatically replanting seedlings. The rice transplanter comprises a machine frame, a walking device, a seedling box, a seedling feeding mechanism and a transplanting mechanism, wherein a ship plate and an inclined plate are arranged on the machine frame, the seedling feeding mechanism is arranged in the seedling box, a plurality of seedlingdoors and the transplanting mechanism are arranged on the ship plate, and a dragging type seedling replanting machine is connected to the machine frame and comprises a top plate, a dragging rod, a seedling replanting mechanism and an adjustable dragging wheel, a seedling replanting cavity is arranged in the seedling replanting mechanism, a plurality of fifth conveying belts and seedling replantingdoors and replanting seedling preassembling boxes which are arranged at the two ends of the fifth conveying belts and correspond to the fifth conveying belts in a one-to-one correspondence mode are arranged in the replanting cavity, and a second light touch switch is arranged on the side face of the replanting seedling door, a seedling replanting air cylinder is arranged above the seed supplementing seedling door, and a pair of photoelectric detection devices are arranged on the front side of the lower portion of each replanting seedling door. By using the rice transplanter, the seedling canbe replanted on shortage position during the seedling shortage period, and the labor cost of manual replanting is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a rice transplanter for automatically replenishing seedlings. Background technique [0002] A rice transplanter is an agricultural machine that implants rice seedlings into a paddy field. Existing rice transplanter generally comprises frame, running gear, seedling box, rice seedling delivery mechanism and rice seedling transplanting mechanism. When planting, the seedling delivery mechanism sends the seedlings to the seedling door, and the seedling transplanting mechanism implants the seedlings within the scope of the seedling door into the soil in the field. Generally take an elliptical action curve. The action is accomplished by means of a planetary mechanism of rotating or deforming gears, and the forward engine can drive these action machines at the same time. [0003] The existing rice transplanter generally has a plurality of seedling boxes integrated when ...

AI Technical Summary

Problems solved by technology

This kind of rice transplanter requires the seedlings to grow neatly. If there is a lack of seedlings in the seedlings, it will lead to the lack of seedlings during transplanting, and it needs to be replanted manually.

At the same time, in the existing rice transplanter, the end faces of the seedling blocks after being transplanted will loosen, and the rice shoots will fall, which will easily lead to the lack of seedlings in the rear row of rice seedlings when they are transplanted.

[0004] Since manual replanting of seedlings consumes a lot of labor costs, it is necessary to develop a replanting machine that lacks seedlings during transplanting
