Working principle:

the first step: the trampling mechanism 1 is connected with the base mechanism 2 and is positioned on the earth ground inside the greenhouse film 5, when a worker enters the greenhouse to work, the trampling bag 109 is continuously trampled, the trampling bag 109 is pressed down to enable the second spring 110 to shrink, the pulling rope 116 is loose, the sealing plate 115 is enabled to seal the second air pipe 112 under the pulling force of the third spring 114, air inside the second spring 110 enters the greenhouse through the first air pipe 111, when the trampling bag 109 is driven by the second spring 110 to prop up again, the sealing plate 115 returns, at the moment, outside air can be conducted into the second spring 110 through the second air pipe 112 and the third air pipe 205, so that when the worker walks at will inside the greenhouse, more outside fresh air can be introduced into the greenhouse, and the air environment inside the greenhouse is improved.

And a second step of: when the greenhouse needs to be insulated at night, the first air pipe 111 can be pulled and connected into the air valve pipe 408, so that the air bag 407 extends out of the bag groove 406 and expands, and the inner layer of the greenhouse film 5 is filled with one layer of air bag 407, thereby being beneficial to the insulation effect of the greenhouse at night, and the operation of expanding the air bag 407 is very simple and quick.

And a third step of: when the device is installed, the second connecting ring 202 close to the trampling mechanism 1 and the inserting column 108 are correspondingly sleeved, then the inserting bin 203 is pressed and inserted into the ground, then the moving mechanism 3 is positioned at a specific position in the base mechanism 2 through two sides, and finally the greenhouse can be installed by covering the greenhouse film 5 on the outer side of the air rib mechanism 4, so that the greenhouse is convenient to fix and the installation operation is simple and convenient.

Fourth step: when dismantling the big-arch shelter, remove the moving mechanism 3 of both sides to the direction that keeps away from each other, thereby make the whole tiling of air rib mechanism 4 in the inside of base mechanism 2, the rib thick stick 404 cover connects in the inside of rib groove 402 simultaneously, will trample mechanism 1 and base mechanism 2 dismantlement afterwards, and will trample mechanism 1 and overturn the back up and down and stretch, will insert the post 108 and correspond in inserting the storehouse 203, thereby make the big-arch shelter wholly accomodate, trample the bag 109 simultaneously and cover the upper surface at air rib mechanism 4, the lower surface of base mechanism 2 protection air rib mechanism 4, the accomodate and the protection of big-arch shelter of being convenient for.

Fifth step: through the existence of air rib mechanism 4, dock rib 401 through rib bar 404, when air rib mechanism 4 wholly presents the arc, the part that rib 401 is higher than rib bar 404 just can separate with the trend of rib bar 404 to make its top perk, canopy membrane 5 cover connect in the outside of air rib mechanism 4 this moment, and the top inside of canopy membrane 5 receives is the support of the upper end of rib 401, thereby can be better raise the canopy top, improve the inside space of big-arch shelter, the effectual canopy height that risees the large-span big-arch shelter.

Sixth step: after the trampling mechanism 1, the base mechanism 2 and the land are fixed, the position of the moving mechanism 3 can be adjusted still, the moving mechanism 3 is pushed in the direction approaching to each other through the design of the shapes of the tooth block 306 and the tooth 206, the inclined planes of the tooth block 206 and the tooth block 306 are butted at the moment, so that the tooth block 306 can automatically shrink in the first adjusting groove 303 under the collision in the advancing process, the moving mechanism 3 is convenient to advance, after the advancing is completed, the reverse position is the plane butt joint of the tooth block 306 and the tooth 206, the self-locking of the adjustment of the greenhouse is completed, and the adjusting capability of the greenhouse installation is greatly improved.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
