A longitudinal automatic seedling supply device and control method for a rice transplanter, which is composed of a seedling storage platform, a power transmission mechanism, an exit slideway, a host computer, and an ECU. The seedling storage platform as a whole is placed in a sloping style with a high front and a low rear. It is divided into 2 to 3 layers of structure. The seedling path of each layer of the storage platform is 190cm long, and the exit slideway is connected to the rear of the storage platform. The seedling tray can be directly sent into the seedling planting platform. The seedling tray is placed on the tensioned seedling storage platform conveyor belt, the power transmission mechanism is on the rear right side of the seedling storage platform, and the DC gear motor drives the conveyor belt to run through the V-belt, electromagnetic clutch, hexagonal shaft and roller. The photoelectric encoder of the seedling storage platform is in close contact with the conveyor belt, counting its pulse square wave to estimate whether the seedling tray is removed; the photoelectric encoder of the seedling planting platform is in close contact with the seedling tray, counting its pulse square wave to estimate whether the seedling tray is blocked. The automatic navigation software of the upper computer monitors the working conditions of the seedling planting platform and the seedling storage platform every time the electric steering wheel is controlled, and dispatches and controls the seedling feeding tray. The device can realize the purpose of unmanned operation of the rice transplanter.
Description
technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a rice transplanting machine and a control method thereof. Background technique [0002] High-speed rice transplanters have been widely promoted in our country, and the operating efficiency has also been greatly improved. Under the double-cropping and three-cropping rice cropping system in the south, or the single-cropping rice planting area in the cold northeast, seedling raising and transplanting are essential agronomic requirements. For example, double-cropping continuous cropping rice in the southern region needs to be raised in greenhouses before the Qingming Festival, and early rice transplanting needs to be started during the rainy season; in the hot dog days, after the early rice is harvested, the late rice must be planted before the beginning of autumn. Such a rice farming system made full use of natural resources and labor resources, and played a very ...
