Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically a vegetable planting greenhouse with water collection function. Background Technology

[0002] Existing vegetable greenhouses are frame-and-film structures with excellent heat insulation properties, enabling people to eat out-of-season vegetables. Generally, vegetable greenhouses use bamboo or steel frames covered with one or more layers of insulating plastic film, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growing vegetables inside, ensuring good heat retention within the greenhouse.

[0003] According to Chinese Patent Publication No. CN221128113U, a vegetable greenhouse with water collection function is disclosed, including a water collection trough. A fixing plate is fixedly connected to the inner left side of the water collection trough. The main body of the greenhouse is fixedly installed on the top of the fixing plate. A filter screen is fixedly connected to the inner wall of the water collection trough and is located below the fixing plate. A cleaning mechanism is provided on the water collection trough. The cleaning mechanism includes a housing. The housing is fixedly connected to the front of the water collection trough. This type of vegetable greenhouse with water collection function filters rainwater through a screen, preventing debris from affecting plant irrigation. A motor drives a lead screw to rotate, which in turn moves a mounting plate horizontally within a limiting groove. This movement of the mounting plate, along with a cleaning brush, removes accumulated debris from the screen, preventing clogging and improving its effectiveness. However, during heavy snowfalls, snow can easily accumulate on the greenhouse roof, potentially causing collapse and posing a safety hazard. Therefore, this water-collecting vegetable greenhouse is proposed to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a vegetable greenhouse with water collection function, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vegetable planting greenhouse with water collection function, including a greenhouse body, a support column fixedly connected to the bottom of the greenhouse body, and a water collection tank fixedly connected to the front of the support column.

[0006] Preferably, a cleaning mechanism is provided on the top of the greenhouse body. The cleaning mechanism includes a motor, and the output end of the motor is fixedly connected to a threaded rod through a coupling. A threaded sleeve is threadedly connected to the outer wall of the threaded rod.

[0007] Preferably, a vertical plate is fixedly connected to the top of the greenhouse body, the threaded rod is rotatably connected to the vertical plate through a bearing, and a first scraper is fixedly connected to the front and rear sides of the threaded sleeve respectively. The first scraper contacts the greenhouse body, and the threaded sleeve is slidably connected to the top of the greenhouse body.

[0008] Preferably, a corrugated plate is fixedly connected to the top of the vertical plate, and a fixed plate is fixedly connected to the front of the threaded sleeve. A striking rod is movably inserted through the fixed plate and extends to its upper and lower sides. The striking rod contacts the corrugated plate, and a spring is fitted on the outer wall of the striking rod. When there is snow or debris on the top of the greenhouse body that needs to be cleaned, the motor of the cleaning mechanism is activated. The motor drives the threaded rod to rotate. Since the threaded rod and the vertical plate are rotatably connected through bearings, the stability of its rotation is ensured. The threaded sleeve, which is threadedly connected to the threaded rod, moves horizontally under the action of rotation. Because it is slidably connected to the top of the greenhouse body, it reciprocates along a predetermined trajectory. During the movement, the first scraper fixed to the threaded sleeve can scrape away the snow or dust on the roof, effectively preventing the risk of collapse caused by snow accumulation. The scraped snow or rainwater flows into the water collection tank along the roof surface.

[0009] Preferably, the water collection tank is provided with a scraping mechanism, which includes a filter screen that is fixedly connected inside the water collection tank.

[0010] Preferably, a connecting rod is fixedly connected to the front of the first scraper, and a second scraper is fixedly connected to the bottom of the connecting rod. The second scraper contacts the filter screen. When the first scraper moves horizontally with the threaded sleeve, the connecting rod fixed to its front moves synchronously. The second scraper at the bottom of the connecting rod also reciprocates horizontally inside the water collection tank. Because the second scraper contacts the surface of the filter screen fixed to the inner wall of the water collection tank, its movement can sweep away accumulated leaves, mud, and other debris on the filter screen to one side, preventing the filter screen holes from clogging. This ensures that the collected rainwater can be smoothly filtered and stored for subsequent irrigation. Rainwater or snowmelt from the roof flows into the water collection tank along the inclined surface of the greenhouse body. The water first passes through the filter screen, where impurities are intercepted. The filtered clean water is stored in the water collection tank and can be used for irrigation of vegetables in the greenhouse at any time, realizing the recycling of water resources.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. This type of vegetable greenhouse with water collection function, by installing a cleaning mechanism consisting of a motor, a threaded rod, and a first scraper on the top of the greenhouse body, can efficiently and automatically remove snow or dust from the greenhouse roof. The removed rainwater or melted snow can flow smoothly into the water collection tank, and the intermittent tapping of the greenhouse by the tapping rod can promote the loosening of snow, thereby improving the cleaning effect.

[0013] 2. This type of vegetable greenhouse with water collection function uses a cleaning mechanism that is linked to a second scraper inside the water collection tank via a connecting rod to simultaneously scrape and clean the filter screen. This integrated design organically combines three major functions: greenhouse roof maintenance, water resource collection, and filter screen anti-clogging. It has a high degree of automation and effectively improves the reliability and working efficiency of the entire system. Attached Figure Description

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0023] Please see Figure 1-4 One embodiment of this utility model is as follows: a vegetable greenhouse with water collection function, including a greenhouse body 1, a support column 2 fixedly connected to the bottom of the greenhouse body 1, a water collection tank 3 fixedly connected to the front of the support column 2, a cleaning mechanism 4 provided on the top of the greenhouse body 1, the cleaning mechanism 4 including a motor 411, a threaded rod 412 fixedly connected to the output end of the motor 411 through a coupling, a threaded sleeve 414 threadedly connected to the outer wall of the threaded rod 412, a vertical plate 413 fixedly connected to the top of the greenhouse body 1, the threaded rod 412 and the vertical plate 413 being rotatably connected through a bearing, and the threaded sleeve 414... The threaded sleeve 414 is slidably connected to the top of the greenhouse body 1. First scrapers 415 are fixedly connected to the front and rear sides of the threaded sleeve 414, respectively. The first scrapers 415 contact the greenhouse body 1. A corrugated plate 416 is fixedly connected to the top of the vertical plate 413. A fixing plate 417 is fixedly connected to the front of the threaded sleeve 414. A striking rod 418 moves through the interior of the fixing plate 417 and extends to its upper and lower sides. The striking rod 418 contacts the corrugated plate 416. A spring 419 is fitted on the outer wall of the striking rod 418. When there is snow or debris on the top of the greenhouse body 1 that needs to be cleaned, the motor 411 of the cleaning mechanism 4 is activated. The motor 411 drives the threaded rod 412 to rotate. Since the threaded rod 412 and the vertical plate 413 are rotatably connected through bearings, the stability of its rotation is ensured. The threaded sleeve 414, threadedly connected to the threaded rod 412, moves horizontally under the action of rotation. Because it is slidably connected to the top of the greenhouse body 1, it reciprocates along a predetermined trajectory. The first scraper 415, fixed to the threaded sleeve 414, can scrape away the snow or dust on the roof during movement, effectively preventing the risk of collapse caused by snow accumulation. The snow or rainwater scraped off flows into the water collection tank 3 along the roof surface.

[0024] Working principle: When there is snow or debris on the top of the greenhouse body 1 that needs to be cleaned, the motor 411 of the cleaning mechanism 4 is activated. The motor 411 drives the threaded rod 412 to rotate. Since the threaded rod 412 is rotatably connected to the vertical plate 413 through a bearing, its rotational stability is ensured. The threaded sleeve 414, which is threaded to the threaded rod 412, moves horizontally under the action of rotation. Since it is slidably connected to the top of the greenhouse body 1, it reciprocates along a predetermined trajectory. The first scraper 415, which is fixed on the threaded sleeve 414, can scrape away the snow or dust on the roof during the movement, effectively preventing the risk of collapse caused by snow accumulation. The scraped snow or rainwater flows into the water collection tank 3 along the roof surface. When the threaded sleeve 414 moves laterally, it drives the striking rod 418 to move laterally. The striking rod 418 vibrates up and down under the action of the corrugated plate 416, thereby striking the greenhouse body 1.

[0025] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, a scraping mechanism 5 is provided inside the water collection tank 3. The scraping mechanism 5 includes a filter screen 511, which is fixedly connected inside the water collection tank 3. A connecting rod 512 is fixedly connected to the front of a first scraper 415, and a second scraper 513 is fixedly connected to the bottom of the connecting rod 512. The second scraper 513 contacts the filter screen 511. When the first scraper 415 moves horizontally with the threaded sleeve 414, the connecting rod 512 fixed to its front moves synchronously. The second scraper 513 at the bottom of the connecting rod 512 also reciprocates horizontally inside the water collection tank 3. Because the second scraper 513 contacts the surface of the filter screen 511 fixed to the inner wall of the water collection tank 3, its movement can sweep away the leaves, mud, and other debris accumulated on the filter screen 511 to one side, preventing the filter screen holes from becoming clogged. This ensures that the collected rainwater can be smoothly filtered and stored for subsequent irrigation. Rainwater or snowmelt from the roof flows into the water collection tank 3 along the inclined surface of the greenhouse body 1. The water first passes through the filter screen 511, where impurities are intercepted. The filtered clean water is stored in the water collection tank 3 and can be used for irrigation of vegetables in the greenhouse at any time, realizing the recycling of water resources.

[0026] Working principle: When the first scraper 415 moves horizontally with the threaded sleeve 414, the connecting rod 512 fixed to its front moves synchronously. The second scraper 513 at the bottom of the connecting rod 512 also reciprocates horizontally inside the water collection tank 3. Since the second scraper 513 contacts the surface of the filter screen 511 fixed to the inner wall of the water collection tank 3, its movement sweeps away accumulated leaves, mud, and other debris from the filter screen 511 to one side, preventing clogging of the filter screen holes. This ensures that the collected rainwater can be smoothly filtered and stored for subsequent irrigation. Rainwater or melted snow from the roof flows into the water collection tank 3 along the inclined surface of the greenhouse body 1. The water first passes through the filter screen 511, where impurities are intercepted. The filtered clean water is stored in the water collection tank 3 and can be used for irrigation of vegetables in the greenhouse at any time, realizing the recycling of water resources.
