Abstract
The utility model discloses a ventilation device for a tomato planting greenhouse. The ventilation device comprises rocker arms, cranks, universal joints, scrolls and plastic films; one end of each plastic film is fixed on a fixed strip on the surface of the greenhouse, and the other end is fixed on one scroll; the plastic films can be wound on the scrolls respectively; one end of each universal joint is connected to one side of one scroll, and the other end is fixedly connected with one rocker arm; and the cranks are connected to the tail ends of the rocker arms respectively. The ventilation device for the tomato planting greenhouse can be turned on or off manually, is low in cost, realizes circulation and exchange of air inside and outside the greenhouse, achieves the purpose of internal ventilation of the greenhouse and ensures that tomatoes can grow healthily.
Description
Technical field
The utility model relates to a kind of ventilation unit, is meant a kind of tomato planting booth ventilation unit especially.
Background technology
When adopting the greenhouse gardening tomato, will note the environmental temperature of tomato growth especially, especially in the winter time, night, temperature was lower, if do not take suitable insulation measure to increase environmental temperature, then can have a strong impact on the growth quality of tomato.To the noon on daytime, illumination is strong, temperature recovery, and canopy temperature rises also very fast, can not ventilate, lower the temperature like booth, also can have a strong impact on the plantation quality of tomato.
The utility model content
The problem that the utility model will solve is the deficiency that overcomes in the background technology; A kind of tomato planting booth ventilation unit is provided, this tomato planting booth ventilation unit, employing can be opened, can be closed mode; Regulate the environmental temperature of tomato growth, be beneficial to the tomato healthy growth.
For addressing the above problem, the utility model is taked following technical scheme:
A kind of tomato planting booth ventilation unit of the utility model is made up of rocking bar, crank, universal joint, spool, plastic film.One end of plastic film is fixed on the fixed strip on booth surface, and the other end is fixed on the spool, and plastic film can be wound on the spool, and an end of universal joint is connected a side of spool, and the other end is fixedly connected with rocking bar, and crank is connected the end of rocking bar.When needing to regulate the booth interior environment temperature, rotatable crank drives spool and rotates through rocking bar, universal joint, if rotate to top, booth surface, then plastic film is wound on the spool, and the booth surface is able to open, and reaches ventilation, cooling; If two side bottoms rotate to the booth surface, then plastic film spreads out along big shed surface, and the booth surface is able to close, and reaches insulation, heats.Through this unlatching, close mode, realize booth inner air and outer air circulation exchange, reach the purpose of booth inner ventilation.
A corrective measure of this programme is that plastic film is the light-transmission type plastic film.
Take such scheme, have the following advantages:
Can find out by above scheme, because tomato planting booth ventilation unit is made up of rocking bar, crank, universal joint, spool, plastic film; And an end of plastic film is fixed on the fixed strip on booth surface, and the other end is fixed on the spool, and plastic film can be wound on the spool; Thisly manually open, can close mode, cost is low, has realized the circulation of booth inner air and outer air; Reached the purpose of booth inner ventilation, made tomato ability healthy growth.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of tomato planting booth ventilation unit of the utility model is made up of rocking bar 1, crank 2, universal joint 3, spool 4, plastic film 5; One end of said plastic film 5 is fixed on the fixed strip 6 on booth surface 7, and the other end is fixed on the spool 4, and an end of said universal joint 3 is connected a side of spool 4, and the other end is fixedly connected with rocking bar 1, and said crank 2 is connected the end of rocking bar 1.
