Description

Technical Field

[0001] This utility model relates to the technical field of shading mechanisms, specifically to a greenhouse shading mechanism that is easy to adjust. Background Technology

[0002] A greenhouse is a facility used for agricultural production, providing suitable environmental conditions for crop growth. In the shading system of a greenhouse, the curtain motor is a commonly used drive component. Traditional curtain motors mostly use a chain and gear meshing transmission method. However, in actual use, curtain motors are prone to problems such as wear, stretching, and even breakage of chain drives, resulting in high maintenance costs and short service life. In addition, the transmission method of the curtain motor has limited precision, which is not convenient to meet the needs of greenhouses for precise opening and closing of shading nets, thus making it difficult to accurately control the light and temperature inside the greenhouse.

[0003] Therefore, we proposed an easily adjustable greenhouse shading mechanism, which modifies the traditional curtain-pulling motor into a geared motor with a lead screw. By improving the transmission mechanism, we solved the problems of low transmission accuracy, high maintenance cost and short service life of the traditional curtain-pulling motor, and achieved efficient, precise and stable control of the shading net's opening and closing, thereby improving the overall performance of the greenhouse shading system.

[0037] 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.

[0038] Please see Figures 1 to 4 An easily adjustable greenhouse shading mechanism includes a mounting plate 1, on which a lead screw assembly and a transmission mechanism are mounted. Two lead screw nuts 2 are symmetrically mounted on the lead screw assembly. The transmission mechanism includes mounting rods 3, positioning frames 4, adjusting plates 5, adjusting frames 6, adjusting connecting blocks 7, and a cleaning assembly. Two mounting rods 3 are symmetrically and detachably connected to both sides of the mounting plate 1. Positioning frames 4 are fixedly connected to each mounting rod 3. Two mounting brackets 21 are symmetrically connected to each mounting rod 3. Mounting screws 22 are threadedly connected between the mounting brackets 21 and the mounting plate 1, allowing the mounting rods 3 to be installed and removed on the mounting plate 1, thereby enabling the replacement of positioning frames 4, etc., and adjustment. The section plate 5 is movably mounted on each positioning frame 4. The bottom end of the adjusting plate 5 is fixedly connected to a moving block 23. The positioning frame 4 has a moving groove for the moving block 23 to slide, which improves the stability of the adjusting plate 5 moving on the positioning frame 4. The adjusting plate 5 is fixedly connected to the adjacent wire nut 2, which makes it easy for the adjusting plate 5 and the wire nut 2 to move synchronously and stably. At the same time, the adjusting plate 5 can stably support the wire nut 2. There are two adjusting frames 6, which are symmetrically rotated on both sides of each wire nut 2. The adjusting connecting block 7 is fixedly connected to each adjusting frame 6, and the adjusting connecting block 7 has an adjusting connecting port, which makes it easy to stably connect with the shade net connecting parts. The cleaning component can be detachably installed on each wire nut 2.

[0039] refer to Figure 1 as well as Figure 4The lead screw assembly includes a coupling 8, a geared motor 9, and a lead screw 10. The coupling 8 is mounted on the top of the mounting plate 1. The output end of the geared motor 9 is fixedly connected to the coupling 8. There are two lead screws 10, which are symmetrically and detachably connected to the coupling 8. Two connectors 19 are symmetrically and detachably connected to the coupling 8. The connectors 19 have connection ports that match the lead screws 10. Multiple connecting screws 20 are threaded between the connectors 19 and the coupling 8 to facilitate the installation and removal of the lead screws 10 on the coupling 8. The two lead screws 10 have threads in opposite directions. Two nuts 2 are threadedly connected to the two lead screws 10 respectively.

[0040] The chain and gear meshing transmission of the traditional curtain-pulling motor is replaced with a lead screw and nut transmission. The lead screw 10 is connected to the output shaft of the geared motor 9, and the nut 2 is fitted on the lead screw 10 and can move along the axial direction of the lead screw 10. The reduction part of the original curtain-pulling motor is optimized by adjusting the gear ratio and surface hardening treatment of the reduction gear, such as using carburizing and quenching process, to improve the surface hardness and fatigue resistance of the gear, reduce wear, and extend service life.

[0041] The geared motor 9 is a modified version of the curtain-pulling motor, which solves the problems of low transmission accuracy, high maintenance cost and short service life of traditional curtain-pulling motors. At the same time, the transmission method of the lead screw 10, lead nut 2 and adjusting plate 5 is much more accurate than the traditional chain and gear transmission. It can accurately control the positioning accuracy of the shading net and eliminate the easily worn chain transmission. The transmission components of lead screw 10 and lead nut 2 have a longer service life and are easy to maintain. At the same time, the wear of lead screw 10 and lead nut 2 is small. Under normal use, there is no need to replace parts frequently, which reduces maintenance costs and frequency, thereby improving the overall performance of the greenhouse shading system.

[0042] refer to Figure 1 as well as Figure 2 The cleaning assembly includes a cleaning frame 11, a cleaning ring 12, and cleaning bristles 14. The cleaning frame 11 is detachably connected to one side of the nut 2. The cleaning ring 12 is fixedly connected to the cleaning frame 11. Two driven screws 13 are threaded between the cleaning ring 12 and the nut 2. By turning the two driven screws 13 between the cleaning ring 12 and the nut 2, the cleaning ring 12 and the cleaning frame 11 can be installed and removed on the nut 2, so as to facilitate the installation and removal of multiple sets of cleaning bristles 14, thereby facilitating the replacement and cleaning of the cleaning bristles 14. The cleaning bristles 14 are configured in multiple sets, and all sets of cleaning bristles 14 are fixedly connected to the cleaning frame 11.

[0043] When the nut 2 moves on the lead screw 10, multiple sets of cleaning bristles 14 also move on the lead screw 10 at the same time, which can clean the debris and impurities on the lead screw 10 from all directions, reducing the impact of debris and impurities on the movement of the nut 2, thereby improving the movement efficiency of the nut 2 on the lead screw 10.

[0044] refer to Figure 2 Two adjustment ports that match the adjustment frame 6 are symmetrically opened on the nut 2, and an adjustment ring 15 is fixedly fitted on the adjustment frame 6. Multiple adjustment screws 16 are threadedly connected between the adjustment ring 15 and the nut 2, and multiple adjustment screw grooves that match the adjustment screws 16 are opened on the adjustment ring 15.

[0045] Rotating the adjusting frame 6 within the adjusting port allows for adjustment of the connection angle of the adjusting block 7, enabling the adjusting block 7 to connect with shade nets at different angles. This facilitates adjustment of the shading angle of the shade net. Simultaneously, turning the adjusting screw 16 between the adjusting ring 15 and the nut 2 fixes the position of the adjusting frame 6 and the adjusting block 7 on one side of the nut 2, thereby improving the stability of the movement of the adjusting frame 6, the adjusting block 7, and the shade net driven by the nut 2.

[0046] refer to Figure 3 A locking rod 17 is fixedly connected to one side of the lead screw 10. A locking slot for the locking rod 17 to rotate is provided on the positioning frame 4. A locking plate 18 is fixedly connected to one side of the locking rod 17. A locking groove for the locking plate 18 to rotate is provided on the positioning frame 4.

[0047] When the lead screw 10 rotates, the clamping rod 17 rotates within the clamping jaw, and the clamping plate 18 rotates within the clamping groove, which improves the stability of the lead screw 10 rotating on the positioning frame 4, thereby improving the stability of the nut 2 moving axially on the lead screw 10.

[0048] It should be further explained that the geared motor 9 can be electrically connected to an intelligent control system via a control circuit. The intelligent control system includes a light sensor and a temperature sensor. The light sensor and temperature sensor can collect environmental parameters such as light intensity and temperature in the greenhouse in real time and transmit the data to the control circuit. When the light intensity is higher than the set upper limit, the light sensor control circuit sends a command to start the geared motor 9, causing the geared motor 9 to drive the lead screw 10 to rotate. The lead screw nut 2 will move axially on the lead screw 10, and drive the shading net to unfold through the adjusting frame 6, adjusting connecting block 7 and the connecting parts of the shading net. As the shading net unfolds, the light sensor continuously monitors the position of the shading net. When the preset unfolding position is reached, the control circuit controls the geared motor 9 to stop running. When the light intensity drops to the set lower limit, the control circuit controls the geared motor 9 to reverse, and the lead screw nut 2 moves in the opposite direction, driving the shading net to retract. In the entire operation process, the geared motor 9 and the lead screw 10 and lead screw nut 2 transmission system work together to achieve precise and efficient control of the opening and closing of the shading net.

[0049] In this embodiment, the high-precision machined lead screw 10 and the output shaft of the geared motor 9 are first coaxially connected through the coupling 8. Then, the lead screw nut 2 is fitted onto the lead screw 10 to ensure the straightness of the lead screw nut 2's movement on the lead screw 10. After that, the sensors of the intelligent control system are installed in suitable positions inside the greenhouse, such as the light sensor installed on the roof where it can receive sufficient light, and the temperature sensor installed in a representative area inside the greenhouse. The control circuit is then electrically connected to the geared motor 9, the light sensor, and the temperature sensor.

[0050] Then, the two adjusting frames 6 are rotated at the same angle on the two wire nuts 2 to adjust the angle of the adjusting block 7 and the shading net. After the adjustment is completed, the two lead screws 10 are rotated at the same time, so that the two wire nuts 2 move towards each other. This allows the shading net to be expanded or contracted according to the shading needs of the greenhouse, thus improving the shading effect of the greenhouse.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
