DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The embodiment of the present application provides an automatic cleaning device for the roof of a multi-span greenhouse, which can solve the problem that most of the existing multi-span greenhouses in the relevant technology usually do not have a roof cleaning function, require manual cleaning, and the cleaning process is time-consuming, labor-intensive, and inefficient.

[0027] See also Figure 1-Figure 3An automatic cleaning device for the roof of a multi-span greenhouse comprises: a multi-span greenhouse main body 1 formed by splicing at least two greenhouses, a cleaning piece 2 being slidingly provided on the top of the multi-span greenhouse main body 1, the cleaning piece 2 comprising a scraping portion 21 and a purge portion 22 connected to each other, the scraping portion 21 being used to scrape off impurities accumulated on the top of the multi-span greenhouse main body 1, and the purge portion 22 being used to supply air to clean the impurities remaining on the top of the multi-span greenhouse main body 1; a driving member 3 is provided on the side of the multi-span greenhouse main body 1, the driving member 3 being used to drive the cleaning piece 2 to reciprocate along the length of the multi-span greenhouse main body 1, and two guide assemblies 4 are relatively provided on the multi-span greenhouse main body 1, the guide assembly 4 being used to guide the movement of the cleaning piece 2.

[0028] In actual use, the driving member 3 starts to work. It is usually located on the side of the multi-span greenhouse body 1, driving the cleaning member 2 to move back and forth along the length direction of the multi-span greenhouse body 1. This movement method ensures that the cleaning member 2 can cover the entire greenhouse roof without missing any area that needs to be cleaned.

[0029] During the cleaning process, the scraper 21 first contacts the impurities on the top of the multi-span greenhouse body 1 and removes most of the accumulated impurities such as dust, fallen leaves, etc. by physical scraping. The design of the scraper 21 is usually matched with the shape of the greenhouse roof to ensure the best scraping effect.

[0030] Next, the purge unit 22 begins to operate, sweeping away any remaining impurities. The blower 222 is typically positioned at an angle to better remove impurities from the greenhouse roof. This ensures that the top of the multi-span greenhouse body 1 is thoroughly cleaned of impurities.

[0031] In order to ensure that the cleaning piece 2 can move stably and accurately, two guide components 4 are relatively arranged on the multi-span greenhouse body 1 to provide the necessary guidance and support for the cleaning piece 2 so that it can remain stable during the movement.

[0032] The coordinated use of the scraping unit 21, the purge unit 22, the drive element 3, and the guide assembly 4 enables automated cleaning, significantly saving labor costs and reducing safety risks associated with improper manual operation. Furthermore, the cleaning unit 2 integrates both scraping and purge methods, enabling faster and more thorough removal of impurities from the roof of a multi-span greenhouse, significantly improving cleaning efficiency.

[0033] By regularly cleaning impurities from the greenhouse roof, the light and temperature distribution within the greenhouse is improved, providing a more suitable growing environment for crops, thereby increasing crop yield and quality. Furthermore, the cleaning device has a simple structure and is easy to maintain and upgrade. Parameters such as the movement speed and cleaning force of the cleaning member 2 can be adjusted according to actual needs to meet the requirements of different greenhouses.

[0034] Specifically, such as Figure 3 As shown, the scraping portion 21 in this embodiment includes a support plate 211 slidably mounted on the top of the multi-span greenhouse body 1. The support plate 211 is formed by splicing together several semicircular plates. A scraping plate 212 is provided at the bottom of the support plate 211. Both the scraping plate 212 and the support plate 211 are adapted to the shape of the multi-span greenhouse body 1. The bottom of the scraping plate 212 is in contact with the top surface of the multi-span greenhouse body 1. The scraping plate 212 is made of rubber or plastic.

[0035] The support plate 211 is formed by splicing together several semicircular plates. This design not only provides the support plate 211 with sufficient strength and stability to support the scraping plate 212 for efficient scraping, but also adapts to the various curves and angles that may exist on the roof of the multi-span greenhouse main body 1. By adjusting the number of semicircular plates and the splicing method, the support plate 211 can be easily adapted to the shape of the multi-span greenhouse main body 1, ensuring that scraping operations fully cover the entire greenhouse roof.

[0036] The scraper blade 212 directly contacts the top surface of the multi-span greenhouse body 1 to scrape away impurities. To ensure effective scraping, the bottom of the scraper blade 212 is in contact with the top surface of the multi-span greenhouse body 1. Furthermore, the scraper blade 212 is made of a soft, wear-resistant material such as rubber or plastic. This material not only has excellent elasticity and wear resistance, ensuring long-term scraping effectiveness, but also does not damage the top surface of the multi-span greenhouse body 1, thus protecting the safety of the greenhouse structure.

[0037] In one embodiment, Figure 3 As shown, the purge unit 22 includes a mounting frame 221 mounted on a support plate 211. The mounting frame 221 is provided with a plurality of fans 222, which are distributed along the length of the support plate 211 and are connected to the mounting frame 221 via bolts. The fans 222 are arranged at an angle.

[0038] The mounting frame 221 serves as a support and fixing structure for the fan 222.

[0039] The fans 222 are distributed along the length of the support plate 211. The number and distribution density of the fans should be reasonably designed according to the width and height of the greenhouse roof and the type and amount of debris to ensure that sufficient airflow can be generated to blow the entire roof area.

[0040] The blower 222 is convenient to disassembly and maintenance by bolt connection with the mounting frame 221. Meanwhile, the bolt connection also has certain flexibility, and the position and angle of the blower can be adjusted as needed to achieve the best purge effect.

[0041] When the fan 222 is arranged at an angle, the inclined fan can generate a stronger impact force, which helps to blow off stubborn debris such as dirt and snow on the roof. At the same time, the inclined arrangement can also increase the contact area between the airflow and the roof surface, thereby improving the cleaning effect.

[0042] Specifically, such as Figure 3 As shown, the driving member 3 in this embodiment includes four unwinders 31, and the four unwinders 31 are distributed at the front and rear ends of both sides of the multi-span greenhouse body 1; a transmission block 32 is arranged between two adjacent unwinders 31, and the two transmission blocks 32 are arranged at the two ends of the bottom of the support plate 211, and the transmission block 32 is driven to move back and forth along the length of the multi-span greenhouse body 1 by the two adjacent unwinders 31.

[0043] The four unwinders 31 are respectively distributed on both sides and the front and rear ends of the multi-span greenhouse body 1. This distribution method ensures the balanced transmission of driving force.

[0044] The two transmission blocks 32 are respectively arranged at the two ends of the bottom of the support plate 211 and are connected to the adjacent unwinder 31 to ensure that the connection with the unwinder 31 is stable and can smoothly transmit power.

[0045] Specifically, when the cleaning member 2 needs to move forward, the two unwinders 31 at the front end can be started to tighten the rope or chain, and the two unwinders 31 at the rear end can be started to loosen the rope or chain; conversely, when the cleaning member 2 needs to move backward, the opposite operation can be performed.

[0046] Further, such as Figure 3 and Figure 4 As shown, the unwinder 31 includes a shell 311 arranged on the multi-span greenhouse body 1, and a reel 312 is rotatably arranged inside the shell 311. A cable 313 is wound around the reel 312. A through hole 314 is opened on the shell 311, and one end of the cable 313 passes through the through hole 314 and is connected to the transmission block 32; the unwinder 31 also includes a driving motor 315 arranged on the shell 311, and the output shaft of the driving motor 315 is connected to either end of the reel 312 and is used to drive the reel 312 to rotate.

[0047] The main part of the unwinder 31 is a shell 311 arranged on the main body of the multi-span greenhouse 1. A reel 312 is rotatably arranged inside the shell. The reel 312 is used to wind the cable 313. The cable 313 serves as a transmission medium and is retracted and released through the rotation of the reel 312, thereby driving the movement of the transmission block 32 and the cleaning piece 2.

[0048] One end of the cable 313 is wound from the reel 312, passes through a through hole 314 in the housing 311, and is connected to the transmission block 32. This connection ensures that the cable 313 can be smoothly retracted and extended when the reel 312 rotates, and drives the transmission block 32 and the cleaning unit 2 to move along the length of the multi-span greenhouse body 1.

[0049] The output shaft of the drive motor 315 is connected to either end of the reel 312 . By controlling the start and stop and the rotation direction of the drive motor 315 , the rotation of the reel 312 and the retraction and extension of the cable 313 can be achieved.

[0050] The reel 312 is driven to rotate by the drive motor 315, thereby realizing the retraction and extension of the cable 313 and the movement of the transmission block 32 and the cleaning member 2. This driving method has the characteristics of high efficiency and stability, and can ensure that the cleaning member 2 moves smoothly and quickly on the multi-span greenhouse body 1.

[0051] In one embodiment, the guide assembly 4 includes fixed plates 41 relatively arranged at both ends of the multi-span greenhouse body 1, a sliding rod 42 is arranged between the relatively fixed plates 41, and two sliding holes corresponding to the sliding rod 42 are relatively opened on the support plate 211. The sliding rod 42 is inserted into the corresponding sliding holes, and the two sliding rods 42 slide together with the support plate 211.

[0052] The fixed plate 41 serves as a support and guide base to ensure that it does not move or deform during the entire cleaning process. The slide bar 42 serves as a track for the support plate 211 to move. The two ends of the slide bar 42 are respectively connected to the two fixed plates 41 to ensure that it remains straight and stable over the entire length.

[0053] The sliding hole size is fully matched with the slide bar 42 to ensure that the support plate 211 can move steadily along the slide bar 42. When the support plate 211 is driven by the driving member 3, it can slide on the slide bar 42 through the sliding hole, thereby realizing the linear movement of the cleaning member 2.
