Abstract
The utility model relates to a long circular keel rabbet ventilation window which consists of four arc skeletons, fixing bolts and connection plates, wherein the four arc skeletons are assembled into a whole by using the fixing bolts through the connection plates; and the skeletons are in the shape of a keel rabbet. The product is simple in structure and reasonable in design; as the long circular keel rabbet ventilation window is adopted, a greenhouse does not need to be completely opened during the ventilation; and each ventilation window has independent ventilation function and indirect ventilation function, so that no damage is caused to seedlings, benefit is brought to the growth and development of the seedlings, the cost is low, the use and operation are convenient, and benefit is brought to the popularization and application.
Description
Technical field: the utility model relates to a kind of Long Circle keel groove vent window.
Background technology: at present, two parallel and booth front and back of keel groove are adopted in the ventilation of existing raising rice seedlings booth usually; When needing to ventilate, tens meters need of whole booth are all opened, and not only waste time and energy; Troublesome poeration; Inefficiency, and the g and D of infringement rice shoot are unfavorable for applying.
Summary of the invention: the purpose of the utility model is to overcome above-mentioned shortcoming; A kind of Long Circle keel groove vent window is provided, and it has mainly solved the ventilation of existing raising rice seedlings booth, adopts two parallel and booth front and back of keel groove usually; When needing to ventilate; Whole booth need all be opened, troublesome poeration, problems such as infringement rice shoot.The purpose of the utility model is achieved in that Long Circle keel groove vent window is made up of: skeleton, hold-down screw, connecting plate.Four arc skeletons are assembled into one through connecting plate with hold-down screw, and skeleton is the keel flute profile.This product structure is simple, and is reasonable in design, owing to adopted Long Circle keel groove vent window; Do not need during ventilation whole booth all opened, but each vent window independent ventilation, indirect draft does not cause damage to rice shoot; Help growing of rice shoot; Cost is low, uses easy to operately, helps applying.
