Abstract

The invention discloses a flue-cured greenhouse seedling three-dimensional rotation automatic control device. The invention adopts the scheme that end brackets are mounted at the two ends of a seedling pool; the seedling pool contains seedling liquid; a central rotating shaft is connected between the end brackets; a rotating arm is hinged on the central rotating shaft; the end head is correspondingly connected with a tray shaft longitudinally; a fence tray is hinged on the tray shaft; a seedling disk is placed in the fence tray; a servo motor is connected with a speed reducer, a shaft coupler and the central rotating shaft sequentially; and a controller is connected with the servo motor. The flue-cured greenhouse seedling three-dimensional rotation automatic control device changes the traditional floating seedling method for placing the seedling disk into the seedling pool in parallel and controls the servo motor to drive the seedling disk to rotationally and alternatively change positions to meet the requirement of the seedling disk on nutrient solution in the seedling pool and solves the problem about illumination on the lower layer of seedling disk, so that each seedling disk uniformly absorbs sunlight and water, the seedling quality is improved, and the device is applicable to factory-like seedling production.

Description

Technical field

[0001] The invention relates to a greenhouse seedling raising device, in particular to a flue-cured tobacco greenhouse seedling raising three-dimensional rotation automatic control which uses electric power to drive a fence tray to rotate around a central rotating shaft, so that the seedling tray is continuously changed in a three-dimensional space, thereby improving the space utilization rate in the greenhouse The device belongs to the field of agricultural automation technology. Background technique

[0002] The nursery of flue-cured tobacco is the primary link in tobacco production. Cultivating timely, sufficient, neat and robust tobacco seedlings is a prerequisite for the realization of the tobacco planting plan and the basis for obtaining high-quality, high-efficiency, and low-cost tobacco. Chinese tobacco science and technology workers have done a lot of research work around cultivating suitable, uniform, full and strong tobacco seedlings. In the 1950s and...

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings:

[0012] Set up a nursery pond (12) in the flue-cured tobacco nursery greenhouse, install an end bracket (6) at each end of the nursery pond (12), the nursery pond (12) is filled with seedling liquid (13), and two end brackets (6) ) The central rotating shaft (7) is connected in the middle, and eight groups of rotating arms (8) are hinged on the central rotating shaft (7) at intervals of 1.7m in the longitudinal direction. There are six rotating arms (8) in each group, and there are two rotating arms ( 8) The distance is 60°. The end of each pivot arm (8) is longitudinally connected to the tray shaft (9). The tray shaft (9) and the central shaft (7) are parallel to each other, and hinge on the tray shaft (9). Connect seven fence trays (9), place the seedling tray (11) in the fence tray (10), install the motor support (5) next to the left end support (6), the servo...
