Description

Greenhouse with automatic stretching solar protection devices

Technical field

The utility model relates to greenhouses to cultivate farm implements, and in particular to a kind of greenhouse with automatic stretching solar protection devices.

Background technique

Greenhouse cultivation is widely used in modern agriculture, and existing greenhouse, support frame is generally rectangle, and is covered in each face There is film.Greenhouse is frequently utilized for kind of planting pollution-free and vegetables in improper season, can also plant flowers, due to southern area rainwater is more, Sunshine-duration is long, and is chronically at temperature higher state, if reducing the temperature in greenhouse by the way of exhausting cooling, consumes Electricity is big, at high cost, currently, the mode generallyd use is the side film design by greenhouse into movable, passes through wound membrane The volume of device control side film is put, so that it is open to form greenhouse, is reduced the temperature in greenhouse.Former side face is thin Film uses movable greenhouse, although may be implemented centainly to radiate, effect is not fine.In order to play rainproof effect, Top film cannot be removed again, and summer temp is very high in greenhouse, be unfavorable for plant growth.

So during long-term cropping, due to season and requirement of the crop different growth periods to illumination not Together, need greenhouse top install additional solar protection devices, existing solar protection devices be mostly it is fixed, sunshade position is fixed, can not Sunshade position and effect is adjusted flexibly, also there is the special solar protection devices using motorized structure, but higher cost in the prior art, It is not suitable for small-sized raiser, therefore, based on the defect of above-mentioned existing greenhouse, needs to improve existing greenhouse.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of greenhouse with automatic stretching solar protection devices.

Technical solution is as follows:

A kind of greenhouse with automatic stretching solar protection devices is set at the top of the canopy body including the canopy body fixed on the ground There is arch, the arch includes a keel and several arch bars, and the keel are arranged along the length direction of greenhouse, the arch bar Width direction along greenhouse is placed equidistant with, and film is covered on the arch, and key is: the canopy is equipped in vitro can be automatic The solar protection devices of stretching, the solar protection devices include puggaree spool, guide groove and walking dolly, canopy body rear and front end The guide groove is respectively equipped on outer wall, the guide groove extends to the other side along the external wall of canopy from a side bottom of the canopy body Bottom, the puggaree spool are arranged along the length direction of greenhouse, and the both ends of the puggaree spool are fastened on described two lead Into slot, the pull rod of the puggaree spool is slided along the guide groove, is inserted with transmission inside the pull rod along its length Bar, the drive rod are rotatablely connected by bearing and the pull rod, and the both ends of the drive rod are pierced by the pull rod respectively, described The either end of drive rod is connected with the walking dolly, and the walking dolly drives the drive rod to slide along the guide groove. The effect of the program is: walking dolly can drive pull rod to move along guide groove, so as to adjust the area coverage of puggaree, according to Different sun-shading requirements adjust the latched position of puggaree.

Preferably, the drive rod is cased with transmission gear, the cell wall of the guide groove close to its both ends outside respectively The corresponding transmission gear is equipped with the gear latch being mutually adapted with it.The effect of the program is: convenient for drive rod along guiding Slot is mobile, while can guarantee the fixation position of pull rod and guide groove.

Preferably, the walking dolly includes motor fixing seat and motor, and the motor is mounted on the motor In fixing seat, the bearing rod of the motor is fixedly connected with the drive rod, and the drive rod turns with the bearing rod of the motor It is dynamic.The effect of the program is: being rotated by motor, can make drive rod rotation automatically, so that pull rod be made to move in guide groove.

Preferably, the both ends of the pull rod are respectively equipped with hook, and the outer wall elongatedness direction of the guide groove is equal Even to be equipped with multiple hook protrusions, the hook is mutually adapted with the hook protrusion.The effect of the program is: when puggaree position After adjusting, the fixation position of pull rod can be further ensured that by hook.

The utility model has the advantages that puggaree covers canopy using the greenhouse with automatic stretching solar protection devices of the utility model Body plays a certain protective role canopy body, prevents direct sunlight, prevents from being rapidly heated in greenhouse and can be automatically and flexibly Sunshade position and effect are adjusted, it is low in cost, it is easy to operate.
