[0002] When growing seedlings in a greenhouse, it is necessary to use a sunshade net to shade the seedling trays. A sunshade net is a net-shaped material used to block sunlight, usually made of plastic materials such as polyethylene and polypropylene. Its main function is to reduce direct sunlight, lower the temperature, and protect plants, buildings, or outdoor activity areas from the strong sunlight.

[0003] In order to prevent plants from being irradiated by strong sunlight, it is necessary to use a sunshade net to shade and protect them. For example, in the prior art, the Chinese patent publication number "CN221203518U" discloses a sunshade net with a winding function. The winding pull rope is connected to the end side of the sunshade net body through a pull rope fixing plate. The first motor drives the pull rope reel to pull the winding pull rope to complete the unfolding of the sunshade net body. A winding shaft column is arranged on one side of the second motor, and the second motor drives the winding shaft column to complete the winding of the sunshade net body. A cleaning mechanism is arranged at the rear side of the sunshade net body. The cleaning mechanism includes a cleaning roller, and a cleaning strip is arranged on the upper part of the cleaning roller. An electric drive structure is adopted, replacing manual work with electricity, which facilitates the use of the sunshade net body and improves the winding efficiency of the sunshade net body. And a cleaning roller is arranged on one side of the sunshade net body, and the cleaning roller is synchronously driven by the second motor. During the winding operation, the sundries adhered to the surface of the sunshade net body can be removed by the cleaning roller, avoiding the influence of sundries remaining on the winding operation, and greatly improving the use stability of the device.

[0004] In actual operation, it is necessary to use a pair of motors to wind and unwind the sunshade net, which increases the production cost of the device and is not conducive to large-scale use. And the connecting belt and the fixing plate are fixed by locking bolts, which is not convenient for disassembling the sunshade net, and then not convenient for replacing and cleaning the sunshade net, and the practicability is poor. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages of large production cost of the device and inconvenience in disassembling the sunshade net in the prior art, and to propose a net-receiving mechanism for a sunshade net.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] Wherein, connection belts are arranged at both ends of the sunshade net, and the connection belts on both sides are detachably connected to the winding roller and the unwinding roller respectively through fixing members.

[0009] Furthermore, the winding mechanism further includes a motor. The winding roller and the unwinding roller are respectively rotatably connected to both sides of the top of the chassis through a pair of support frames. The motor is fixedly installed on the side of one of the support frames, and the shaft end of the motor is fixedly connected to one end of the winding roller.

[0010] Furthermore, a torsion spring box is fixedly installed between the opposite sides of the pair of support frames. A torsion spring is fixedly connected inside the torsion spring box, and a movable seat is rotatably connected to the open end thereof. The end face of the movable seat is fixedly connected to the torsion spring through an extension rod, and the unwinding roller is fixedly installed between the pair of movable seats.

[0011] Furthermore, the winding roller and the unwinding roller have the same structure, and extension parts are formed by extending on their sides. Accommodating grooves are formed on the sides of the extension parts. A plurality of the connection belts are fixedly connected to both ends of the sunshade net, and the other ends of the connection belts are fixedly connected to fixing plates, and the fixing plates are arranged in the accommodating grooves.

[0012] Furthermore, the fixing member includes guide columns fixedly installed on both sides of the top of the extension part. A limiting convex column is arranged at one end of the guide column, and a baffle is slidably connected thereto. The baffle is in an L-shaped structure and can abut against the fixing plate.

[0013] Furthermore, a spring is sleeved on the periphery of the guide column, and both ends of the spring are fixedly connected to the limiting convex column and the side of the baffle respectively.

[0014] For the sunshade net winding mechanism proposed by the present utility model, the beneficial effects are as follows: The present utility model drives the winding roller to wind the sunshade net through a motor, and after unlocking the shaft end of the motor, the tension of the torsion spring is used to drive the sunshade net to unfold.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments

[0020] Refer to Figures 1-3 , a net-receiving mechanism for a sunshade net, including a chassis 1, a winding mechanism 2 is arranged on the top of the chassis 1, the winding mechanism 2 includes a winding roller 3 and an unwinding roller 4, and a sunshade net 5 is arranged between the winding roller 3 and the unwinding roller 4

[0021] Among them, connecting belts 51 are arranged at both ends of the sunshade net 5, and the connecting belts 51 on both sides are detachably connected to the winding roller 3 and the unwinding roller 4 respectively through fixing members 6

[0022] Furthermore, the winding mechanism 2 further includes a motor 21. The winding roller 3 and the unwinding roller 4 are respectively rotatably connected to both sides of the top of the chassis 1 through a pair of support frames 11. The motor 21 is fixedly installed on the side surface of one of the support frames 11, and the shaft end of the motor 21 is fixedly connected to one end of the winding roller 3

[0023] It should be added that the motor 21 is a motor with a brake in the prior art, that is, the shaft end of the motor 21 can be self-locked after power-off, so as to prevent the winding roller 3 from rotating freely and avoid the accidental unfolding of the sunshade net 5 under the tension of the spring 23

[0024] Furthermore, a spring box 22 is fixedly installed between the opposite sides of a pair of support frames 11. A spring 23 is fixedly connected inside the spring box 22, and a movable seat 24 is rotatably connected to its open end. The end surface of the movable seat 24 is fixedly connected to the spring 23 through an extension rod, and the unwinding roller 4 is fixedly installed between a pair of movable seats 24

[0025] More specifically, the winding roller 3 and the unwinding roller 4 have the same structure, and extension parts 25 are formed by extending on their sides. A receiving groove 26 is formed on the side of the extension part 25. Both ends of the sunshade net 5 are fixedly connected with a plurality of connecting bands 51. The other ends of the connecting bands 51 are fixedly connected with a fixing plate 27, and the fixing plate 27 is arranged in the receiving groove 26.

[0026] It is worth mentioning that under normal circumstances, the unwinding roller 4 winds the connecting band 51, and the sunshade net 5 is unfolded under the traction effect to achieve the effect of supporting the sunshade net 5. After that, when the winding roller 3 winds the sunshade net 5, the winding roller 3 winds the sunshade net 5, and the unwinding roller 4 unwinds the connecting band 51;

[0027] Therefore, the lengths of the connecting bands 51 on both sides are inconsistent, and the length of the connecting band 51 connected to the unwinding roller 4 is greater than the length of the connecting band 51 on the other side.

[0028] Generally speaking, the fixing member 6 includes guiding columns 61 fixedly installed on both sides of the top of the extension part 25. One end of the guiding column 61 is provided with a limiting convex column 62 and is slidably connected with a baffle 63. The baffle 63 is in an L-shaped structure and can abut against the fixing plate 27.

[0029] Finally, a spring 64 is sleeved on the periphery of the guiding column 61, and both ends of the spring 64 are fixedly connected with the side surfaces of the limiting convex column 62 and the baffle 63 respectively.

[0030] In specific operations, protrusion parts are integrally formed on both sides of the baffle 63. The baffle 63 can be easily pushed through the protrusion parts. When the baffle 63 is separated from the fixing plate 27, the sunshade net 5 can be disassembled.

[0031] Working mode; When working, the motor 21 is powered on to unlock its shaft end so that the winding roller 3 can rotate. The unwinding roller 4 rotates under the tension of the coil spring 23, and then winds the connecting band 51, and the connecting band 51 then pulls the sunshade net 5 to unfold;

[0032] Push the baffle 63 to move it. When the baffle 63 is separated from the fixing plate 27, the sunshade net 5 can be disassembled. After replacing the new sunshade net 5, insert the fixing plate 27 into the receiving groove 26. The baffle 63 moves under the action of the spring 64 and abuts against the fixing plate 27 to achieve the effect of fixing the sunshade net 5.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
