Description

Technical Field

[0001] This invention relates to the field of smart agriculture, specifically to a smart agriculture system and method based on greenhouse cultivation. Background Technology

[0002] In the wave of agricultural modernization, facility agriculture has become the key to ensuring the supply of agricultural products and improving production efficiency, and greenhouse planting is widely used. However, traditional greenhouses rely on manual experience for management, which has problems such as high labor costs, inaccurate environmental monitoring, and lagging regulation, resulting in resource waste, crop growth being affected, and restricting agricultural efficiency and sustainable development.

[0016] A method for a smart agriculture system based on greenhouse cultivation includes the following steps:

[0017] S1. Fix the curved plate and the pressing plate with bolts, and install the rotating device above the greenhouse film;

[0018] S2. When sand and snow accumulate on the leeward side of the greenhouse film, the rotating device is triggered to drive the rectangular rod to rotate.

[0019] S3. The spiral winding causes the card slot collar to move upward, and the torsion spring drives the arc-shaped scraper to scrape off the accumulated sand and snow in close contact with the greenhouse film.

[0020] S4. The scraped sand and snow slide down the arc-shaped surface of the arc-shaped scraper to the guide belt and are quickly discharged through the smooth surface.

[0021] S5. The screw drives the sliding frame to move, and the arc-shaped scraper, in conjunction with the torsion spring, scrapes away the sand and snow accumulated in the concave part of the greenhouse film.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This smart agriculture system based on greenhouse cultivation uses an arc-shaped scraper to remove accumulated sand and snow on the leeward side of the greenhouse film. The arc shape allows impurities to slide out from above and presses the arc-shaped scraper into the surface of the greenhouse film, thus solving the problem of impurities accumulating on the leeward side.

[0024] 2. This smart agriculture system based on greenhouse cultivation uses a guide belt. When accumulated sand and snow slide off the curved surface of the arc-shaped scraper, they fall onto the surface of the guide belt and slide off through its smooth surface. At the same time, the guide belt protects the greenhouse film, preventing direct abrasion of the film by sand and snow.

[0025] 3. This smart agriculture system based on greenhouse cultivation uses a torsion spring to make an arc-shaped scraper contact the surface of the greenhouse film. The arc-shaped scraper removes accumulated sand and snow from the concave areas of the greenhouse film and cleans debris from the concave areas.

[0026] 4. This smart agriculture system based on greenhouse cultivation increases the contact length between the rotating column and the greenhouse film by setting up a rotating frame that is rotatably connected to the rotating column. This provides auxiliary support for the two cleaning mechanisms, allowing their own weight to be distributed through the rotating frame, thus avoiding direct action on the greenhouse film and deformation.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Example 1: See Figure 1 - As shown in the figure, the present invention provides a technical solution: a smart agriculture system based on greenhouse cultivation, including a support rod 1, a greenhouse film 2 fixedly connected to the outer surface of the support rod 1, a cleaning mechanism 3 snapped onto the outer surface of the support rod 1, and a second cleaning mechanism 4 rotatably connected inside the first cleaning mechanism 3. The first cleaning mechanism 3 includes:

[0040] An arc-shaped bent plate 31 has a clamping plate 311 inside it. A through-hole post 312 is rotatably connected to the outer surface of the clamping plate 311. A limit frame 313 is threaded inside the clamping plate 311 and is used to limit the through-hole post 312.

[0041] The spiral 34 has a grooved collar 341 fixedly connected to its outer surface. The grooved collar 341 is rotatably connected to a rotating column 342. An arc-shaped scraper 344 is sleeved on the outer surface of the rotating column 342. The arc-shaped scraper 344 is used to scrape the leeward side of the greenhouse film 2.

[0042] Guide belt 36 is used to isolate impurities.

[0043] The cleaning mechanism 3 also includes a rotating device 314, which is fixedly connected to the through-hole post 312. A rectangular rod 32 is fixedly connected to the outer surface of the rotating device 314. A sliding ring 33 is slidably connected to the outer surface of the rectangular rod 32. A rotating frame 35 is fixedly connected to the outer surface of the spiral 34. A threaded rod 37 is threadedly connected to the inside of the sliding ring 33. A sliding ring 38 is threadedly connected to the outer surface of the threaded rod 37. The sliding ring 38 is used to limit the rotation range of the spiral 34.

[0044] The arc-shaped bending plate 31 is snapped into the supporting bending rod 1, the pressing plate 311 is snapped into the greenhouse film 2, the outer surface of the rotating column 342 is fitted with a torsion spring 343, the torsion spring 343 is fixedly connected to the inner wall of the arc-shaped scraper 344, the guide belt 36 is attached to the surface of the greenhouse film 2, the sliding ring 38 is slidably connected to the rectangular rod 32, and the guide frame 345 is used to guide the spiral line 34.

[0045] The spiral 34 is rotatably connected to the rotating frame 35. The arc-shaped scraper 344 is in contact with the surface of the greenhouse film 2. The spiral 34 is wound around the rectangular rod 32. The torsion spring 343 is used to twist the arc-shaped scraper 344. The threaded rod 37 is used to fix the sliding ring 38. When sand and snow accumulate on the surface of the guide belt 36, the guide belt 36 squeezes the greenhouse film 2, causing the greenhouse film 2 to be concave, affecting the degree of contact between the arc-shaped scraper 344 and the greenhouse film 2. This allows the sand and snow to fall quickly through the smooth surface of the guide belt 36, preventing further accumulation. By adjusting the fixing distance between the threaded rod 37 and the bolt, the position of the sliding ring 38 on the surface of the threaded rod 37 is adjusted, thereby adjusting the winding distance of the spiral 34 so that it can be matched with different support rods 1 and greenhouse film 2.

[0046] When the greenhouse is insulated by the greenhouse film 2, sand and snow will gradually accumulate on the leeward side of the greenhouse film 2, causing the greenhouse film 2 to sag excessively and be subjected to continuous stress, resulting in plastic deformation and affecting the insulation effect of the greenhouse. Therefore, the cleaning mechanism 3 is required to scrape the accumulated sand and snow on the leeward side of the greenhouse film 2 and protect the greenhouse film 2 during the scraping process.

[0047] The working principle of this embodiment is as follows: When using this smart agriculture system based on greenhouse planting, the arc-shaped curved plate 31 and the pressing plate 311 are fixed by bolts, thereby clamping the greenhouse film 2 and the supporting curved rod 1, and fixing the rotating device 314 above the greenhouse film 2. When there is wind, sand and rain or snow, the monitor inside the greenhouse detects the surface of the greenhouse film 2. When sand or snow accumulates on the leeward side, the rotating device 314 drives the rectangular rod 32 to rotate, and the rectangular section of the rectangular rod 32 drives the sliding ring 33 to rotate. The sliding ring 33 causes the spiral 34 to rotate around the surface of the rectangular rod 32 and the threaded rod 37, causing the slotted collar 341 to move upward. The guide frame 345 restricts the winding direction of the spiral 34 so that it does not affect the arc during winding. The scraping action of the arc-shaped scraper 344 involves the torsion spring 343 causing the arc-shaped scraper 344 to twist and adhere to the surface of the greenhouse film 2. This scrapes away accumulated sand and snow on the leeward side of the greenhouse film 2. The scraped sand and snow slide out from under the arc-shaped scraper 344 through its curved surface, compressing the scraper and making it adhere more tightly to the greenhouse film 2. At this time, the accumulated sand and snow fall onto the surface of the guide belt 36. The smooth surface of the guide belt 36 allows the sand and snow to fall quickly, preventing them from accumulating on its surface. This ensures that the arc-shaped scraper 344 adheres tightly to the surface of the greenhouse film 2. Through the continuous winding of the spiral filament 34, the arc-shaped scraper 344 removes accumulated sand and snow from the leeward side of the greenhouse film 2.

[0048] Example 2: Please refer to Figure 1-2. Based on Example 1, the present invention provides the following technical solution: The cleaning mechanism 2 4 includes a screw 41, which is rotatably connected to the limiting frame 313. The outer surface of the sliding frame 42 is threadedly connected to the sliding frame 42. The outer surface of the rectangular rod 32 is slidably connected to the sliding ring 33. The outer surface of the sliding ring 2 38 is fixedly connected to the arc plate 44, and the outer surface of the arc plate 48 is slidably connected to the rotating sleeve 45. The inner wall of the rotating sleeve 45 is fixedly connected to the bearing 452. The inner wall of the bearing 452 is rotatably connected to the limiting shaft 451. The arc plate 44 is used to guide the limiting shaft 451.

[0049] The cleaning mechanism 2 4 also includes a rotating frame 2 46, which is fixedly connected to the limiting rotating shaft 451. A torsion spring 2 461 is fixedly connected to the outer surface of the rotating frame 2 46. The outer surface of the torsion spring 2 461 is fixedly connected to the inner wall of the arc-shaped scraper 2 462. A guide belt 2 47 is rotatably connected to the outer surface of the rotating frame 2 46. A rotating pressure rod 48 is rotatably connected to the outer surface of the guide belt 2 47. The rotating pressure rod 48 is used to limit the guide belt 2 47.

[0050] The sliding frame 42 is rotatably connected to the sliding ring 3 43, the limiting shaft 451 is fixedly connected to the rotating frame 2 46, the bottom surface of the arc-shaped scraper 2 462 is provided with an arc angle, the rotating pressure rod 48 is rotatably connected to the guide belt 1 36, and the rotating pressure rod 48 is used to limit the guide belt 1 36. When the arc-shaped scraper 2 462 is used to scrape away the accumulated sand and snow, the surface of the arc-shaped scraper 2 462 that contacts the greenhouse film 2 is an arc-shaped surface, so as to avoid the arc-shaped scraper 2 462 damaging the surface of the greenhouse film 2 when scraping the position where the accumulated sand and snow are excessively silted up and deformed.

[0051] When scraping away accumulated sand and snow on the leeward side of the greenhouse film 2, the accumulated sand and snow cause the film 2 to be under continuous stress, resulting in concave elastic deformation. This leads to incomplete removal of the accumulated sand and snow. Therefore, cleaning mechanism 2 4 is needed to assist in scraping the film 2 and to provide auxiliary support for cleaning mechanisms 1 3 and 2 4, so that the weight of cleaning mechanisms 1 3 and 2 4 does not cause plastic deformation of the film 2.

[0052] The working principle of this embodiment is as follows: When using this smart agriculture system based on greenhouse planting, when scraping away accumulated sand and snow on the leeward side of the greenhouse film 2, a second rotating frame 46 is engaged inside the rotating column 342. The winding of the spiral wire 34 drives the first cleaning mechanism 3 and the second cleaning mechanism 4 to move. At this time, the rotating sleeve 45 slides on the surface of the arc plate 44. The bearing 452 causes the rotating sleeve 45 and the limiting shaft 451 to rotate, while the limiting shaft 451 is fixed to the second rotating frame 46. Thus, through the guidance of the arc plate 44 and the torsion of the second torsion spring 461, the second arc scraper 462 is made to adhere to the surface of the greenhouse film 2, and the sand is removed by the second arc scraper 462. The snow is scraped off, and the guide belt 47 is brought into contact with the surface of the greenhouse film 2 by the rotation of the pressure rod 48, so that the accumulated sand and snow slide off. At this time, the sliding frame 42 is moved laterally by the screw 41, which in turn moves the cleaning mechanism 4 laterally, so that the scraping position of the arc scraper 462 coincides with the scraping position of the arc scraper 344. The cleaning mechanism 3 and the cleaning mechanism 4 are reset by the rotating device 314. The scraping is then carried out again by the rotating device 314. At this time, the arc surface of the arc scraper 462 is used to scrape off the deformed areas caused by excessive accumulation of sand and snow, so as to completely clean the surface of the greenhouse film 2.

[0053] A method for a smart agriculture system based on greenhouse cultivation includes the following steps:

[0054] S1. Fix the arc-shaped bending plate 31 and the pressing plate 311 with bolts, and install the rotating device 314 above the greenhouse film 2;

[0055] S2. When sand and snow accumulate on the leeward side of the greenhouse film 2, the rotating device 314 is triggered to drive the rectangular rod 32 to rotate.

[0056] S3, the spiral 34 is wound up to move the card slot collar 341 upward, and the torsion spring drives the arc scraper 344 to stick to the greenhouse film 2 to scrape away the accumulated sand and snow.

[0057] S4. The scraped sand and snow slide down the arc-shaped surface of the arc-shaped scraper 344 to the guide belt 36, and are quickly discharged by the smooth surface.

[0058] S5, screw 41 drives sliding frame 42 to move, arc scraper 462 works with torsion spring to scrape away sand and snow accumulated in the concave part of greenhouse film 2.
