Abstract

The utility model provides a ventilating window structure of a greenhouse and belongs to the technical field of novel farmland facilities and agricultural technical equipment. The ventilating window structure of the greenhouse is characterized by comprising sponge, metal hinges, a ventilating window, a window door of the ventilating window, and support springs. The upper end of the window door of the ventilating window is connected with the upper end of the ventilating window through the metal hinges. The lower end of the window door of the ventilating window is connected with the lower end of the ventilating window through the support springs. The sponge is arranged on the window door of the ventilating window. When the sponge absorbs water with the content up to half or more of the capacity of the whole sponge on rainy days, weight of the window door of the ventilating window and weight of the sponge are larger than elastic force of the support springs, and the window door of the ventilating window closes automatically. Conversely, the window door of the ventilating window opens automatically. Therefore, labor can be saved, and safety of crops in the greenhouse is effectively guaranteed.

Description

A kind of booth vent window structure

Technical field

The utility model relates to a kind of booth vent window structure, the technical field of novel on-farm facilities agricultural technology equipment.

Background technology

At present; China is a large agricultural country; Agricultural is the major industry of China, and polyhouse-based agriculture accounts for the most ratio of China, but most booth vent window structure all is to carry out switch through manual work; So not only wasted a large amount of labour cost, and owing to reasons such as the manual control switch is untimely cause causing the heavy losses of crops in the booth because of rainwater gets into booth.

The utility model content

For fear of the generation of above problem, the utility model provides a kind of booth vent window structure, can in time solve the problem of being brought.

The technical scheme that the utility model solves its technical problem is: a kind of booth vent window structure; Belong to novel on-farm facilities agricultural technology equipment technical field, its characteristic comprises cavernous body, metal hinge, vent window, the window of vent window, support spring, is connected through the metal hinge on the window of vent window upper end and the vent window; The window lower end of vent window is connected through support spring with the vent window lower end; Cavernous body is positioned on the window of vent window, and when the cavernous body water absorption reached water absorption half the and above of monoblock cavernous body when raining, the window of vent window and the gravity of cavernous body were greater than the elastic force of support spring; The window of vent window is shut automatically; Otherwise then open automatically, can save the labour like this, can guarantee the safety of the crops in the booth again effectively.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the utility model structural representation;

The window 4 of cavernous body 1, metal hinge 2, vent window 3, vent window, support spring 5 among the figure.

Embodiment

Fig. 1, a kind of booth vent window structure belongs to the improved technical field of novel on-farm facilities agricultural technology equipment; Its characteristic comprises window 4, the support spring 5 of cavernous body 1, metal hinge 2, vent window 3, vent window; Window 4 upper ends of vent window are connected through metal hinge 2 with vent window 3 upper ends, and window 4 lower ends of vent window are connected through support spring 5 with vent window 3 lower ends, and cavernous body 1 is positioned on the window 4 of vent window; When cavernous body 1 water absorption reaches water absorption half the and above of monoblock cavernous body when raining; The window 4 of vent window and the elastic force of the gravity of cavernous body 1 greater than support spring 5, the window 4 of vent window is shut automatically, otherwise then opens automatically; The labour can be saved like this, the safety of the crops in the booth can be guaranteed again effectively.
