Description

Technical Field

[0001] The utility model relates to the technical field of rice transplanting equipment, in particular to a wide and narrow row transplanting mechanism based on a space planetary gear system. Background Art

[0002] A rice transplanter is an agricultural machine that plants rice seedlings in rice fields. Existing rice transplanters generally include a frame, a walking device seedling box, a rice seedling delivery mechanism, and a rice seedling distribution mechanism. When planting, the rice seedling delivery mechanism delivers the rice seedlings to the rice seedling gate, and the rice seedling distribution mechanism plants the rice seedlings within the rice seedling gate range into the soil in the field. In order to maintain a right angle between the seedbed and the ground, the front end of the mechanical claw of the rice seedling distribution mechanism generally moves in an elliptical motion curve. The action is accomplished by a planetary mechanism of a rotating or deformed gear, and the forward engine can drive these action machines at the same time.

[0003] The current rice transplanting robot generally rotates on the same horizontal plane when rotating through the space planetary gear, which makes it difficult to transplant rice in wide and narrow rows. It is necessary to adjust the width of the seedling platform and the position of the seedling taking port before it can be achieved. This operation requires a long time of manual operation, which affects the efficiency and speed of transplanting rice. Utility Model Content
