Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse curtain rolling machines, specifically a greenhouse sunshade curtain rolling machine. Background Technology

[0002] Side-mounted roller blinds are a common type of greenhouse shading roller blinds. Their core design involves installing the drive unit and transmission system on the side of the greenhouse (usually the gable or side wall), and using a horizontal or inclined drive shaft to move the shading or insulation curtains up and down.

[0003] Existing side-mounted rolling shutter machines typically use a single galvanized steel or aluminum alloy pipe as the drive shaft, which runs through the side of the greenhouse. During long-term use, uneven stress or material fatigue can easily cause the shaft to deform, leading to asynchronous winding. Therefore, in order to further improve the structural strength of the drive shaft and avoid asynchronous winding caused by shaft deformation, a greenhouse shading rolling shutter machine is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a greenhouse shading roller shutter machine in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse shading roller shutter machine, comprising a support assembly and a roller shutter assembly, wherein the support assembly provides support and guidance for the operation of the roller shutter assembly, and the roller shutter assembly comprises an electric film roller, a bearing base, a driven-side T-shaped swivel, a winding rod, and a flange.

[0006] There are two flanges and four winding rods. The four winding rods are fixed in the middle of the two flanges and are evenly distributed in a ring around the center of the flanges.

[0007] The driven T-shaped rotating seat is rotatably connected to the bearing base. The bearing base and the electric film roller are supported by two sets of support components. The two flanges are connected to the output ends of the driven T-shaped rotating seat and the electric film roller through flange structures. The electric film roller drives the winding rod, flanges and driven T-shaped rotating seat to rotate as a whole. The ring structure composed of multiple winding rods rotates to perform the operation of raising and lowering the sunshade curtain on the outside of the greenhouse body.

[0008] As a further embodiment of this utility model: the support assembly includes a conical nail, a connecting seat, a rotating bracket, and a telescopic bracket;

[0009] The connecting seat is fixed to the top of the cone nail, the bottom end of the rotating bracket is rotatably connected to the connecting seat, and the telescopic bracket is slidably connected to the inside of the rotating bracket and protrudes to the top of the rotating bracket.

[0010] The outer shell of the electric film winding machine and the outer shell of the bearing base are respectively fixedly connected to the top of the two telescopic brackets on the two sets of support components.

[0011] As a further improvement of this utility model: a support ring is fixed in the middle of the four winding rods, and the outer side of the support ring is formed with four arc-shaped notches that match the outer diameter of the winding rods.

[0012] The support ring is engaged with the outer wall of the winding rod through an arc-shaped notch.

[0013] As a further improvement of this utility model, the outer diameter of the support ring is smaller than the outer diameter of the distribution trajectory of the multiple winding rods.

[0014] As a further improvement of this utility model, multiple support rings are evenly arranged along the long side of the winding rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The roller blind assembly with four retractable rods rolls up and down by rotating the four rods. Compared to the structure of a single drive shaft, the ring structure composed of four retractable rods is less prone to deformation. Furthermore, the support ring in the middle of the four retractable rods further enhances the rods' resistance to deformation, resulting in greater structural strength. This effectively prevents the sunshade from rolling up asynchronously at both ends due to rod deformation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 In this embodiment of the utility model, a greenhouse shading roller shutter machine includes a support component 1 and a roller shutter component 2. The support component 1 provides support and guidance for the operation of the roller shutter component 2. The roller shutter component 2 includes an electric film roller 201, a bearing base 202, a driven side T-shaped swivel 203, a winding rod 204, and a flange 205.

[0024] There are two flanges 205 and four coiling rods 204. The four coiling rods 204 are fixed in the middle of the two flanges 205 and are evenly distributed in a ring around the center of the flanges 205.

[0025] The driven T-shaped rotating seat 203 is rotatably connected to the bearing base 202. The bearing base 202 and the electric film roller 201 are supported by two sets of support components 1. The two flanges 205 are connected to the output ends of the driven T-shaped rotating seat 203 and the electric film roller 201 through the flange structure. The electric film roller 201 drives the winding rod 204, the flange 205 and the driven T-shaped rotating seat 203 to rotate as a whole. The ring structure composed of multiple winding rods 204 is used to rotate to retract and extend the sunshade curtain outside the greenhouse body 3.

[0026] Support assembly 1 includes a tapered nail 101, a connecting seat 102, a rotating bracket 103, and a telescopic bracket 104;

[0027] The connecting seat 102 is fixed to the top of the cone nail 101, the bottom end of the rotating bracket 103 is rotatably connected to the connecting seat 102, and the telescopic bracket 104 is slidably connected to the inside of the rotating bracket 103 and protrudes to the top of the rotating bracket 103.

[0028] The outer shell of the electric film winding machine 201 and the outer shell of the bearing base 202 are respectively fixedly connected to the top of the two telescopic brackets 104 on the two sets of support components 1;

[0029] A support ring 206 is fixed in the middle of the four winding rods 204. The outer side of the support ring 206 has four arc-shaped notches 207 that match the outer diameter of the winding rods 204.

[0030] The support ring 206 is engaged with the outer wall of the winding rod 204 through the arc-shaped notch 207, and multiple support rings 206 are evenly arranged along the long side of the winding rod 204.

[0031] In this embodiment, it should be noted that: when this device is in use, two sets are symmetrically arranged along the center line of the greenhouse body 3, which are used to roll up and down the sunshade curtains (or heat insulation curtains) on both sides of the greenhouse body 3. The bottom end of the sunshade curtain is tied and fixed to a rolling rod 204, and the top end of the sunshade curtain is fixed to the top center of the greenhouse body 3. This structure is the conventional structure for installing existing sunshade curtains, so it is not drawn in the figure.

[0032] When the sunshade curtain is rolled up, the electric film roller 201 is started. The electric film roller 201 drives the winding rod 204, flange 205, and driven T-shaped swivel 203 to rotate as a whole. The rotating winding rod 204 is used to roll up the sunshade curtain. At the same time, the sunshade curtain provides an upward pulling force to the electric film roller 201 in the opposite direction, causing the rotating bracket 103 and telescopic bracket 104 to rotate upward passively. At the same time, the telescopic bracket 104 moves outward passively. (It should be noted that the cone nail 101 is inserted into the soil layer to realize the installation of the support component 1). In this way, the opening and rolling up of the sunshade curtain is realized.

[0033] When unrolling the sunshade curtain, simply reverse the start of the electric film roller 201;

[0034] During the above operation, the sunshade is rolled up and down by rotating the four rolling rods 204. Compared with the structure of a single drive shaft, the ring structure composed of four rolling rods 204 is less prone to deformation. Furthermore, the support ring 206 in the middle of the four rolling rods 204 further enhances the deformation resistance of the rolling rods 204, resulting in greater structural strength. This effectively avoids the situation where the two ends of the sunshade roll up asynchronously due to the deformation of the rolling rods 204.

[0035] Please refer to this carefully. Figures 1-4 The outer diameter of the support ring 206 is smaller than the outer diameter of the distribution trajectory of the multiple winding rods 204.

[0036] In this embodiment, this structure prevents the support ring 206 from contacting the sunshade curtain wrapped around the four retractable rods 204, thereby avoiding the support ring 206 from causing pressure and wear on the sunshade curtain.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
