Mechanical swinging light-supplementing device for fruits and vegetables in greenhouse

Abstract

The invention relates to a mechanical swinging light-supplementing device for fruits and vegetables in a greenhouse. The mechanical swinging light-supplementing device comprises a swinging rod, a big gear, a lampshade swinging shaft, a small gear, a connecting rod, a crank, a stepping motor, a control box, a rack, a lampshade, a light source, a lamp base and the like. A crank swinging rod mechanism is combined with the stepping motor and a programmable logic controller is used for controlling, so that the demand on mechanical swinging light-supplementing for the fruits and vegetables in the greenhouse is met and the illumination for the fruits and vegetables in the greenhouse is maintained at an optimal state for a long time. Under the control mode, the structure is simple and reliable and the cost is saved. The mechanical swinging light-supplementing device has the characteristics of simple and useful property, convenience in mounting and adjusting, huge market potential, obvious economic benefit and social benefit, wide application prospect, and the like.

Description

technical field [0001] The invention relates to a mechanical swing light supplement device for fruits and vegetables in a greenhouse, which belongs to the field of facility agriculture. Background technique [0002] In the production of facility agriculture in northern my country, due to the cold winter, the facility agriculture greenhouse occupies an important position. The main function of the greenhouse is to separate the growth environment of fruits and vegetables planted in it from the outside world, and maintain the natural conditions required for the growth of fruits and vegetables in the greenhouse to maintain the growth of crops. , where fill light is an important factor. At present, there have been researches on the application of automatic control equipment to supplement light for crops in greenhouses, such as patent application number: ZL 201120030112.3, invention name: LED plant supplementary light; patent application number: ZL 201120025798.7, invention name: pl...

AI Technical Summary

Problems solved by technology

At present, there have been researches on the application of automatic control equipment to supplement light for crops in greenhouses, such as patent application number: ZL 201120030112.3, invention name: LED plant supplementary light; patent application number: ZL 201120025798.7, invention name: plant intelligent supplementary light system, etc., but the shortcoming is that it only conducts research on light source equipment

In the past, there was a way to switch the supplementary light on and off at a fixed time. The disadvantage is that the frequent activation of the supplementary light reduces the service life. At the same time, all the supplementary lights are lit at the same time. The load is too large, which is easy to cause damage to the equipment.

At present, there are all kinds of fruit and vegetable supplementary lighting equipment on the market, but adjustable and periodic mechanical swing supplementary lighting devices have not yet been seen.
