Description

Technical Field

[0001] The utility model belongs to the technical field of anti-hail nets, and in particular relates to an anti-hail net device which can be automatically retracted and extended. Background Art

[0002] For many years, hail disasters have been one of the main natural disasters in the main production areas of apples, peaches and other fruits and vegetable greenhouses, causing huge economic losses to fruit farmers. The emergence of intelligent hail-proof net folding and unfolding devices for greenhouses has better solved this problem. The folding and unfolding devices of intelligent hail-proof nets for greenhouses are intelligently controlled by a single-chip microcomputer system. The single-chip microcomputer system can automatically control the operation of the hail-proof device according to the acquired weather information, thereby preventing hail. By utilizing the structure of the greenhouse roof, the chain is driven by a motor to drive the hail-proof net to unfold or tighten. There is no need to invest too much manpower, saving labor costs. When the weather forecast is not accurate enough, the opening of the hail-proof device can be controlled according to the sound and pressure conditions, and the hail-proof device can be opened manually to add more protection for hail prevention. The current hail-proof nets are assembled manually to complete the folding and unfolding work, which is not only labor-intensive but also inefficient. Utility Model Content

[0027] An automatically foldable and deployable hail protection net device comprises a left automatically foldable and deployable component 1 and a right automatically foldable and deployable component 2.

[0028] In the present embodiment: To solve the technical problems existing in the prior art, as disclosed in the background technology above, "currently hail prevention nets are assembled manually to complete the folding and unfolding work, which not only requires a lot of labor but also has low insertion efficiency", in combination with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, the present utility model provides a hail prevention net device that can be automatically folded and unfolded.

[0029] like Figure 1-5 As shown in the figure;

[0033] In this embodiment: the lower rotating shaft seat 16 slides up and down on the pillar 11, pushing the left top rod 17 and the right top rod 18 to change the angle. Since the left top rod 17 and the right top rod 18 are movably connected to the left support rod 14 and the right support rod 15, the left support rod 14 and the right support rod 15 are pushed to change the angle, thereby performing the folding and unfolding operation of the hail protection net.

[0035] In this embodiment: the driving reduction motor 41 drives the driving gear 43 to rotate. Since the driving gear 43 and the driven gear 45 are meshed with each other, the driven gear 45 is driven to rotate. Since the threaded sleeve 44 is fixedly connected to the driven gear 45, the threaded sleeve 44 rotates following the driven gear 45. Since the threaded sleeve 44 is threadedly connected to the external thread 42 of the pillar 11, the threaded sleeve 44 performs axial movement in the up and down directions.

[0036] Working principle of this utility model:

[0037] The driving reduction motor 41 drives the driving gear 43 to rotate. Since the driving gear 43 and the driven gear 45 are meshed with each other, the driven gear 45 is driven to rotate. Since the threaded sleeve 44 is fixedly connected to the driven gear 45, the threaded sleeve 44 rotates with the driven gear 45. Since the threaded sleeve 44 is threadedly connected to the external thread 42 of the pillar 11, the threaded sleeve 44 performs axial movement in the up and down directions, thereby pushing the lower rotating shaft seat 16 to slide up and down on the pillar 11, and pushing the left top rod 17 and the right top rod 18 to change the angle. Since the left support rod 14 and the right support rod 15 are movably connected to the left top rod 17 and the right support rod 18, the left support rod 14 and the right support rod 15 are pushed to change their angles, thereby performing the folding and unfolding operation of the hail protection net. The overall structure is simple, time-saving and labor-saving, and the work efficiency is high.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
