Description

Technical Field

[0001] This application relates to the field of shade cloth winding technology, specifically a shade cloth winding device for agricultural greenhouses. Background Technology

[0002] The agricultural greenhouse shading cloth rewinding device is mainly used to realize the automatic rewinding and unwinding of shading cloth, and to regulate the light and temperature in the greenhouse. It is suitable for greenhouses growing vegetables, flowers, fruits and vegetables, etc., to regulate light intensity and temperature and reduce energy consumption. The core structure of the agricultural greenhouse shading cloth rewinding device consists of a motor, a rewinding roller, a transmission mechanism, and a support structure. The motor drives the rewinding roller to rotate, and the transmission mechanism drives the shading cloth to unfold or rewind. Some parts of the device use counterweights, slide rails and other auxiliary balance to avoid wrinkles or cloth jamming.

[0003] Ventilation openings should be installed on the meter box to promote air convection. The air inlets and outlets should be reasonably distributed to form a good air circulation path. Dustproof screens that prevent small animals from entering can be installed at the ventilation openings to ensure ventilation and heat dissipation while preventing foreign objects from entering the box. For large-capacity meter boxes, small fans can also be considered to accelerate airflow and enhance heat dissipation.

[0004] In humid weather, the outer surface of the shade cloth is in direct contact with the environment, which can easily lead to dew adhering to the outer surface. When the shade cloth in this state is rolled up, the moisture will remain on the surface of the cloth if it is not dried. Over time, this can easily lead to mold and rot, and accelerate the aging of the material. Utility Model Content

[0005] The purpose of this application is to provide a device for rolling up agricultural greenhouse shading cloth to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A greenhouse shading cloth winding device includes: a winding device body, a bonding cleaning mechanism, a fixing mechanism, and a shading protection mechanism. The winding device body includes a winding assembly, a winding assembly, and a shading cloth body. The winding assembly and the winding assembly are respectively disposed on the outer walls of both sides of the greenhouse metal frame. The two ends of the shading cloth body are respectively disposed on the winding assembly and the winding assembly. The winding assembly is composed of a winding roller driven by a motor to rotate. The winding assembly is composed of a steel wire rope wound around a shaft driven by a motor to rotate.

The bonding cleaning mechanism is disposed on the outer wall of the greenhouse metal frame and is bonded to the outer wall surface of the shading cloth body. The fixing mechanism is disposed on one side of the bonding cleaning mechanism, and the shading protection mechanism is disposed on the outer wall of the bonding cleaning mechanism.

[0008] Furthermore, the fitting cleaning mechanism includes a first fixing block whose bottom end is rotatably mounted on one side of the greenhouse metal frame via a rotating shaft. A connecting shaft is welded to the top of the first fixing block, and a positioning block is rotatably mounted on the connecting shaft. An insertion hole is provided inside the positioning block.

[0009] Furthermore, the fitting cleaning mechanism also includes a second fixing block whose bottom end is rotatably mounted on the other side of the greenhouse metal frame via a rotating shaft.

[0010] Furthermore, the fitting cleaning mechanism also includes a first connecting block welded to both sides of the greenhouse metal frame and a second connecting block welded to the outer walls of the first fixing block and the second fixing block respectively.

[0011] Furthermore, the fitting cleaning mechanism also includes a hook spring with one end attached to the two sets of first connecting blocks via hooks, and the other ends of the two sets of hook springs are respectively attached to the second connecting blocks of the first fixing block and the second fixing block via hooks.

[0012] Furthermore, the fitting cleaning mechanism also includes a cleaning roller disposed between the first fixed block and the second fixed block, one end of which is inserted into the insertion hole of the positioning block.

[0013] Furthermore, the fixing mechanism includes a placement groove located at the center of the top of the second fixing block, and the other end of the cleaning roller is disposed inside the placement groove. The two ends of the second fixing block are respectively provided with an installation groove and a limiting groove, and the installation groove and the limiting groove are connected to the placement groove.

[0014] Furthermore, the fixing mechanism also includes a threaded rod with one end rotatably mounted in the mounting groove via a rotating shaft, and a handle is rotatably mounted on the threaded rod. The threaded rod is located inside the placement groove and the limiting groove.

[0015] Furthermore, the shielding and protection mechanism includes a connecting rod with one end welded to the outer wall of the first fixing block and the second fixing block, and the number of the connecting rods is two sets.

[0016] Furthermore, the shielding and protection mechanism also includes a first arc-shaped block welded to the other end of the two sets of connecting rods. The first arc-shaped block has an arc-shaped groove inside, and a second arc-shaped block is slidably disposed inside the arc-shaped groove of the first arc-shaped block. The first arc-shaped block and the second arc-shaped block are disposed outside the cleaning roller.

[0017] By adopting the above technical solution, the cleaning roller can be fully wrapped by rotation.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] (1) By setting up a bonding cleaning mechanism and a fixing mechanism, the cleaning roller of the bonding cleaning mechanism can absorb and clean the dew attached to the surface of the sunshade cloth body during the rolling process by changing the angle, so as to avoid the phenomenon of mold and damage after the rolling is completed. The elasticity of the hook spring ensures that the cleaning roller and the sunshade cloth body will not affect the rolling jamming phenomenon of the sunshade cloth body during the bonding process. The fixing mechanism enables the cleaning roller to be quickly replaced and installed from the bonding cleaning mechanism. No tools are needed during the operation, which can improve the convenience of operation.

[0020] (2) By setting up a shielding protection mechanism and a cleaning roller, the cleaning roller can be wrapped and protected by the shielding protection mechanism during the cleaning process when the sunshade fabric is not rolled up, so as to avoid the cleaning roller being soaked in wet dew for a long time. The dew is isolated by the protection method, which improves the drying of the cleaning roller when cleaning the sunshade fabric. Attached Figure Description

[0032] This application provides a technical solution for an agricultural greenhouse shading cloth winding device, comprising: a winding device body, a bonding cleaning mechanism 4, a fixing mechanism 5, and a shading protection mechanism 6. The winding device body includes a winding assembly 1, a winding assembly 2, and a shading cloth body 3. The winding assembly 1 and the winding assembly 2 are respectively disposed on the outer walls of both sides of the greenhouse metal frame. The two ends of the shading cloth body 3 are respectively disposed on the winding assembly 1 and the winding assembly 2. The winding assembly 1 is composed of a winding roller driven by a motor to rotate. The winding assembly 2 is composed of a steel wire rope wound on a shaft driven by a motor to wind. The two ends of the shading cloth body 3 are respectively disposed on the winding roller of the winding assembly 1 and the steel wire rope of the winding assembly 2.

The fixing mechanism 5 is disposed on one side of the bonding cleaning mechanism 4, and the shading protection mechanism 6 is disposed on the outer wall of the bonding cleaning mechanism 4.

[0033] The fitting cleaning mechanism 4 includes a first fixing block 401 rotatably mounted on one side of the greenhouse metal frame via a rotating shaft at its bottom end. A connecting shaft 402 is welded to the top of the first fixing block 401. A positioning block 403 is rotatably mounted on the connecting shaft 402. An insertion hole is provided inside the positioning block 403. A second fixing block 404 rotatably mounted on the other side of the greenhouse metal frame via a rotating shaft at its bottom end. First connecting blocks 405 are welded to both sides of the greenhouse metal frame. Second connecting blocks 406 are welded to the outer walls of the first fixing block 401 and the second fixing block 404 respectively. A hook spring 407 is mounted on the two sets of first connecting blocks 405 with one end attached via a hook. The other ends of the two sets of hook springs 407 are mounted on the second connecting blocks 406 of the first fixing block 401 and the second fixing block 404 respectively via hooks. A cleaning roller 408 is mounted between the first fixing block 401 and the second fixing block 404. One end of the cleaning roller 408 is inserted into the insertion hole of the positioning block 403.

[0034] The fixing mechanism 5 includes a placement groove 501 located at the center of the top of the second fixing block 404. The other end of the cleaning roller 408 is located inside the placement groove 501. The two ends of the second fixing block 404 are respectively provided with an installation groove 502 and a limiting groove 503. The installation groove 502 and the limiting groove 503 are connected to the placement groove 501. One end of the threaded rod 504 is rotatably mounted in the installation groove 502 via a rotating shaft. A handle 505 is rotatably mounted on the threaded rod 504. The threaded rod 504 is located inside the placement groove 501 and the limiting groove 503.

[0035] The shielding and protection mechanism 6 includes a connecting rod 601 with one end welded to the outer wall of the first fixing block 401 and the second fixing block 404. There are two sets of connecting rods 601. A first arc-shaped block 602 is welded to the other end of the two sets of connecting rods 601. An arc-shaped groove is opened inside the first arc-shaped block 602. A second arc-shaped block 603 is slidably arranged inside the arc-shaped groove of the first arc-shaped block 602. The first arc-shaped block 602 and the second arc-shaped block 603 are arranged outside the cleaning roller 408.

[0036] Working principle: The shading cloth body 3 can be rolled up and down on the greenhouse metal frame through the winding assembly 1 and the winding assembly 2. During the process of the shading cloth body 3 being rolled up and stored by the winding assembly 1, the shading protection mechanism 6 no longer wraps around the cleaning roller 408. At this time, the cleaning roller 408 can be attached to the outer surface of the shading cloth body 3 through the bonding cleaning mechanism 4. Thus, during the rolling displacement of the shading cloth body 3, the dew on the surface of the shading cloth body 3 can be cleaned. When it is necessary to disassemble and replace the cleaning roller 408 periodically, it can be quickly unlocked and replaced through the fixing mechanism 5.

[0037] At this time, the first arc-shaped block 602 is connected to the first fixed block 401 and the second fixed block 404 via the connecting rod 601, so that the first arc-shaped block 602 and the second arc-shaped block 603 inside can wrap and protect the cleaning roller 408. At this time, the second arc-shaped block 603 rotates and shifts inside the first arc-shaped block 602, so that the cleaning roller 408 is no longer protected. The hook springs 407 on the first connecting block 405 and the second connecting block 406 can use their own elasticity to provide the first fixed block 401 and the second fixed block 404 to change the angle through the rotating shaft. At this time, the cleaning roller 408 set inside the first fixed block 401 and the second fixed block 404 will adhere to the surface of the sunshade cloth body 3, and clean it as the sunshade cloth body 3 rolls up and shifts. When the cleaning roller 408 needs to be disassembled and replaced periodically, the handle 505 on the threaded rod 504 is released. The handle 505 no longer adheres to the outer wall of the second fixing block 404. The threaded rod 504 can then change its angle via the rotating shaft in the mounting groove 502. During rotation, the threaded rod 504 moves out of the limiting groove 503 and the mounting groove 502. The threaded rod 504 no longer limits the other end of the cleaning roller 408 in the placement groove 501. With the rotation of the cleaning roller 408, one end of the cleaning roller 408 is inserted into the positioning block 403. The positioning block 403 can then be connected to the first fixing block 401 via the connecting shaft 402. After the angle is changed, it is convenient to pull the cleaning roller 408 out of the insertion hole of the positioning block 403.
