When encountering severe weather such as heavy rain and snow, the film on the surface of the trellis is easily squeezed by the accumulation of rain, snow and hail, resulting in deformation and damage of the film and the trellis. For this reason, we have proposed an agricultural greenhouse. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-5 The utility model provides a technical solution: an agricultural greenhouse, comprising a shed 1, a support frame 2 is arranged in the middle of the outer periphery of the shed 1, a fixing pipe 3 is connected through the middle of the support frame 2, a folding sunshade frame 4 is fixedly installed near the middle of the support frame 2 on the fixing pipe 3, a frame is arranged at equal intervals in the middle of the folding sunshade frame 4, and a synchronization block 43 is fixedly installed on the frame located in the middle of the folding sunshade frame 4, and a fixing block 42 and an adjusting block 44 are fixedly installed on the frames located at both ends of the folding sunshade frame 4;

[0023] The folding sunshade frame 4 is fixedly installed with connecting blocks 41 at equal intervals on both sides, and the fixed block 42, the synchronization block 43, and the adjustment block 44 are respectively fixedly installed with manual winches 5 through brackets. A cable 51 is installed between each group of manual winches 5 and the corresponding connecting block 41, and the two ends of the fixed tube 3 are respectively connected to the adjusting screw 6 through the rotating shaft;

[0024] The support frame 2 is fixedly installed on the ground in the middle of the scaffolding 1, and the folding sunshade frame 4 is installed with waterproof nylon fabric on the frame with equal spacing, so that the folding sunshade frame 4 can be movably unfolded near the crank 61, thereby shielding and protecting the film on the scaffolding 1;

[0025] The manual winch 5 is an existing retractable wire structure, and the model of the manual winch 5 is 2500lb;

[0026] The synchronization block 43 and the corresponding manual winch 5 can be matched according to the number of frames in the folding sunshade frame 4;

[0027] By rotating the adjusting screw 6, the adjusting block 44 on the folding sunshade frame 4 can slide in the second slide groove 32, so that the skeleton in the folding sunshade frame 4 can be unfolded, so that the waterproof nylon cloth surface in the folding sunshade frame 4 can be unfolded, and the surface of the shed 1 and the film can be shielded and protected, so that rain, snow and hail can be blocked, and rain, snow and hail can be prevented from directly piling up and impacting the top film of the shed 1, thereby effectively protecting the shed 1 and the external plastic film. At the same time, the folding sunshade frame 4 can also be retracted to the middle position of the fixed tube 3 by adjusting the screw 6 and the adjusting block 44 to avoid affecting the photosynthesis of crops in the greenhouse. The folding sunshade frame 4 can be unfolded and stored according to needs, which is more practical.

[0028] The cable 51 can be retracted and released by the manual winch 5, so that the inclination of the tough frame on the folding sunshade frame 4 and the top of the scaffolding 1 can be adjusted. The inclination of the folding sunshade frame 4 can be adjusted according to actual needs, so that the rain and snow accumulated on the waterproof nylon fabric of the folding sunshade frame 4 can be guided and adjusted to avoid the accumulation of rain and snow on the waterproof nylon fabric.

[0029] Among them, the first slide groove 31 and the second slide groove 32 are respectively penetrated on both sides and the bottom of the fixed tube 3. The first slide groove 31 and the second slide groove 32 form an isosceles triangle structure. The fixed block 42, the synchronization block 43 and the adjustment block 44 are all located in the inner wall of the second slide groove 32 with a clearance fit. By rotating the adjusting screw 6, the adjustment block 44 on the folding sunshade frame 4 on the fixed tube 3 can slide in the second slide groove 32, so that the skeleton of the folding sunshade frame 4 can be unfolded.

[0030] Among them, the upper brackets of the manual winch 5 located on the same side slide respectively in the inner walls of the first slide groove 31 on the same side. When the adjustment block 44 on the folding sunshade frame 4 is unfolded through threaded transmission, the upper brackets of the manual winch 5 on both sides of the synchronization block 43 can slide and unfold synchronously on the first slide groove 31.

[0031] Among them, the adjusting screw 6 movably passes through the synchronous block 43 and the fixed block 42, the adjusting block 44 is connected with the adjusting block 44 through a thread, and a crank 61 is fixedly installed on the rotating shaft at the outer end of the adjusting screw 6. When the adjusting block 44 on the folding sunshade frame 4 is unfolded through thread transmission, the brackets on the manual winch 5 on both sides of the synchronous block 43 can slide and unfold synchronously on the first slide groove 31, so as to realize shielding and protection of the scaffolding 1 and the surface of the film, so as to block rain, snow and hail, and avoid rain, snow and hail from directly piling up and impacting the film on the top of the scaffolding 1, thereby effectively protecting the scaffolding 1 and the external plastic film.

[0032] Working principle: When in use, the fixed tube 3 on the support frame 2 can be installed on the ground on both sides of the middle of the scaffolding 1 through support. When the film on the scaffolding 1 is shielded and protected, the adjusting screw 6 can be driven to rotate by the crank 61, and the adjusting block 44 on the folding sunshade frame 4 can slide in the second slide groove 32, so that the skeleton in the folding sunshade frame 4 can be unfolded, so that the waterproof nylon cloth surface in the folding sunshade frame 4 can be unfolded, and the scaffolding 1 and the film surface can be shielded and protected. In this way, rain, snow and hail can be blocked, and rain, snow and hail can be prevented from directly piling up and impacting the film on the top of the scaffolding 1, thereby effectively protecting the scaffolding 1 and the external plastic film;

[0033] Similarly, when the crops in the agricultural greenhouse grow normally through photosynthesis, the sunshade frame 4 can be folded and adjusted by adjusting the screw 6 and the adjusting block 44 to shrink to the middle position of the fixed tube 3 to avoid affecting the photosynthesis of the crops in the greenhouse;

[0034] During the use of the folding sunshade frame 4, the cable 51 can be retracted and released by the manual winch 5, so that the inclination of the tough frame on the folding sunshade frame 4 and the top of the scaffolding 1 can be adjusted. Therefore, the inclination of the folding sunshade frame 4 can be adjusted according to actual needs, and the rain and snow accumulated on the waterproof nylon fabric of the folding sunshade frame 4 can be guided and adjusted to avoid the accumulation of rain and snow on the waterproof nylon fabric.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
