Small-sized hand-operated rice transplanter

Abstract

The invention provides a small-sized hand-operated rice transplanter. A frame is connected to a floating plate by use of a support and an adjusting rod; two seedling separating grasping hooks of a seedling separating mechanism on the frame correspond to two seedling outlets of a seedling tray; two groups of seedling stopping blocks of a seedling stopping mechanism on the frame are located under the two seedling outlets of the seedling tray; a first rotating shaft supported on the frame is connected with a rocking handle by use of a first chain transmission mechanism and is connected with a second rotating shaft on the frame by use of a second chain transmission mechanism; tumblers are fixed on the two ends of the second rotating shaft; seedling transplanting arms are hinged to the tumblers, respectively; the upper ends of the seedling transplanting arms are connected to the frame by use of a link mechanism; a seedling separating driving cam is arranged on the first rotating shaft, and is provided with a cam groove and a collision block; a pull rod of the seedling separating mechanism is matched with the cam groove; the collision arm of the seedling stopping mechanism corresponds to the collision block; two ends of the first rotating shaft are provided with seedling grasping hooks and hinged with seedling clamping plates by use of connecting plates; the free end of each seedling clamping plate is in contact with a guide cam on the frame; a seedling reversing plate is arranged under each guide cam and located above a seedling transplanting nick formed in the floating plate.

Description

technical field The invention relates to a rice transplanter, in particular to a small hand-operated rice transplanter. Background technique In traditional rice transplanting, the transplanter holds a large number of seedlings with one hand, separates out a few seedlings with the other hand and inserts them into the paddy field. During the transplanting process, the transplanter is bent over for a long time. Transplanting rice seedlings, the rice transplanting personnel work for a day, often have backaches, difficulty in straightening the waist, and the labor intensity is very high. With the development of society and the application of mechanization, rice transplanters have entered the field of rice transplanting in farming, which has saved the transplanters from the pain of back pain. However, the existing rice transplanters that use engines as power to transplant rice seedlings are usually large in size and heavy in weight, and are suitable for use in plain areas with la...

Problems solved by technology

And this kind of winter paddy field is only suitable for the planting of large seedlings with long plants, which belongs to the production habit of traditional large seedling planting. The existing rice transplanter suitable for shallow water planting is difficult to meet the production needs of traditional large seedling planting. Difficult to promote
