Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and in particular to a greenhouse film winding device. Background Technology

[0002] The greenhouse of this technology mainly consists of a supporting arched frame 100 and a film module 200, with a winding shaft 300 installed on each side of the film module 200. To achieve ventilation and heat dissipation functions, the film module 200 needs to be wound up on one or both sides. Currently, the winding of the film module 200 in existing technologies mainly uses manual and electric methods. For areas where power is difficult to obtain or is far away, a manual method is usually used, requiring two or more operators to wind up or lift the winding shaft 300 at both ends and hang it. This operation is laborious and inefficient.

[0003] Therefore, there is an urgent need to develop a greenhouse film winding device that is simple in structure and reliable in operation. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a greenhouse film winding device. The technical solution adopted by this utility model is as follows:

[0005] A greenhouse film winding device is disclosed for winding a film assembly laid on a supporting arch frame. A winding shaft is provided on each side of the film assembly. The greenhouse film winding device includes a first winding support assembly and a second winding support assembly, respectively located at opposite ends on the same side of the supporting arch frame, and a hand crank connected to either the first or second winding support assembly. The hand crank drives the winding shaft to rotate, thereby winding the film assembly.

[0006] The second winding support assembly includes a lower fixed mounting base, a U-shaped column fixed on the lower fixed mounting base with its opening facing away from the supporting arch frame, a rack fixed in the U-shaped column in the longitudinal direction, a strip groove opened in the U-shaped column in the longitudinal direction, a support shaft that passes through the strip groove, is connected to the winding shaft at one end and to the hand crank at the other end, and a gear sleeved on the support shaft and meshing with the rack; the support shaft slides along the strip groove.

[0007] Furthermore, a take-up reel is provided on the support shaft and on the side near the take-up shaft.

[0008] Furthermore, a first locking hole is provided on the winding reel; several second locking holes are evenly spaced on the U-shaped column; the several second locking holes are arranged along the longitudinal direction; and the distance between two adjacent second locking holes is equal to the circumference of the first locking hole rotating one revolution around the center of the winding reel.

[0009] Furthermore, a locking pin is embedded in both the first locking hole and the second locking hole.

[0010] Furthermore, the end of the support shaft is provided with a first rhomboid hole and a second rhomboid hole; the end of the winding shaft is provided with a first rhomboid post; the first rhomboid post is sleeved in the first rhomboid hole; a second rhomboid post is provided on the hand crank; the second rhomboid post is sleeved in the second rhomboid hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) This utility model sets up a U-shaped column, a rack, a strip groove, a support shaft, a gear and a hand crank. By rotating the hand crank, the gear and the rack mesh and connect, and drive the winding shaft to wind up. At the same time, the support shaft rotates and moves along the strip groove, ensuring the reliability of the winding action.

[0013] (2) By setting a first locking hole, a locking pin and a second locking hole, the locking pin can be inserted to lock when the winding reaches the specified height and the first locking hole and the second locking hole coincide, thus ensuring the reliability of the locking.

[0014] (3) This utility model is easy to install and assemble by setting a first rhomboid column, a second rhomboid column, a first rhomboid hole and a second rhomboid hole.

[0029] like Figures 1 to 5 As shown, this embodiment provides a greenhouse film winding device for winding up a film assembly 200 laid on a supporting arch frame 100; a winding shaft 300 is provided on both sides of the film assembly 200, and a first rhomboid column 301 is provided at the end of the winding shaft 300 for easy installation.

[0030] In this embodiment, the greenhouse film winding device includes a first winding support assembly 400 and a second winding support assembly 500, respectively disposed at two ends on the same side of the supporting arch frame 100 and arranged mirror-image to each other, and a hand crank 600 connected to either the first winding support assembly 400 or the second winding support assembly 500. The hand crank 600 drives the winding shaft 300 to rotate, thereby winding the film assembly 200. A second rhomboid post 601 is provided on the hand crank 600.

[0031] The first winding support assembly 400 and the second winding support assembly 500 in this embodiment have the same structure. Taking the second winding support assembly 500 as an example, it includes a lower fixed mounting base 501, a U-shaped column 502 fixed on the lower fixed mounting base 501 with its opening facing away from the supporting arch frame 100, a rack 503 fixed in the U-shaped column 502 in the longitudinal direction, a strip groove 504 opened in the U-shaped column 502 in the longitudinal direction, a support shaft 505 disposed through the strip groove 504, connected to the winding shaft 300 at one end and connected to the hand crank 600 at the other end, and a gear 506 sleeved on the support shaft 505 and meshing with the rack 503. When the hand crank 600 is rotated, the winding shaft 300 is supported by the strip groove 504, the support shaft 505, the rack 503, and the gear 506, and the support shaft 505 slides along the strip groove 504. For ease of installation, a first rhomboid hole 507 and a second rhomboid hole 511 are provided at the end of the support shaft 505. The first rhomboid post 301 is fitted into the first rhomboid hole 507, and the second rhomboid post 601 is fitted into the second rhomboid hole 511.

[0032] In this embodiment, after the film assembly 200 is wound to a certain height, the winding shaft 300 and the hand crank 600 can be tied to the supporting arch frame 100 using ropes; or a preset winding height can be used for fixing. The preset winding height structure is as follows: a winding reel 508 is provided on the support shaft 505 and on the side close to the winding shaft 300. A first locking hole 509 is provided on the winding reel 508. Several second locking holes 512 are evenly spaced on the U-shaped column 502. The several second locking holes 512 are arranged in the longitudinal direction. The distance between two adjacent second locking holes 512 is equal to the circumference of the first locking hole 509 rotating one revolution around the center of the winding reel 508. When the film assembly 200 is wound to a preset winding height, for example, at the position corresponding to the second locking hole 512 counting upwards from the bottom of the U-shaped column 502, the second locking hole 512 coincides with the first locking hole 509, and a locking pin 510 can be inserted into the first locking hole 509 and the second locking hole 512 for locking. If the film assembly 200 is to be wound higher, the hand crank 600 can be rotated further (provided that the locking pin 510 is released), so that the second locking hole 512 at a higher position on the U-shaped column 502 coincides with the first locking hole 509, and the locking pin 510 can be inserted.

[0033] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
