Abstract

The present invention discloses an automated agricultural greenhouse, which relates to the technical field of agricultural greenhouses and includes a shed frame, a shed film, a dew removal mechanism, and a dirt cleaning mechanism. In the present invention, a photosensitive sensor is used to detect the light intensity inside the multi-span greenhouse, a dew removal mechanism is provided at the side end of the shed frame, and a dirt cleaning mechanism is provided above the shed film at the upper part of the shed frame, so that a humidity stratification with a low humidity upper layer and a high humidity lower layer is automatically formed in the interior space of the multi-span greenhouse, which not only avoids dew condensation and reduces light transmittance but also does not affect the environmental humidity required for agricultural planting. Moreover, the top shed film in the low humidity upper layer environment will not immediately form dew again, and the light transmittance is maintained continuously. At the same time, the driving of the transmission chain also drives a plurality of driven wheels II to rotate synchronously, and drives the scraping member to reciprocate in the groove path where the top of the shed film is connected through a bidirectional screw, so as to achieve the purpose of automatically scraping the dust and snow at the groove where the top of the shed film is connected, further ensuring the light transmission and heat preservation effects in the greenhouse.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural greenhouses, and specifically relates to an automated agricultural greenhouse. Background Art

[0002] Agricultural multi-span greenhouses have a high land utilization rate, relatively uniform temperature distribution and gentle change inside the greenhouse, strong wind resistance, and small-scale mechanized operations can be carried out inside the greenhouse, which is convenient for large-scale management. Therefore, they have developed rapidly in some places in recent years, resulting in regional characteristics. However, the air flow inside the multi-span greenhouse is not smooth and the humidity is high. Especially in winter, there is a serious dew condensation situation, and the formed low light transmission state affects the growth of agricultural plants. The existing technology often uses the method of covering with a non-drip film, and the condensed water droplets flow down along the film surface to improve the light transmittance.

[0003] However, in the long-term use process, it is found that the existing agricultural multi-span greenhouses still have certain drawbacks: First, in order to enhance the light transmittance, the top of each span of the multi-span greenhouse is designed with an arc-shaped bulge. Although the dew condensation will flow down along the curved surface, it will immediately condense again on the flowing greenhouse film under high humidity conditions, and the light transmittance is not continuous; Second, for the groove where the greenhouse films at the top of the multi-span greenhouse are connected, there is a lot of dust accumulated. In winter, the snow accumulates further along the arc of the greenhouse roof towards the groove on the dust with greater resistance, still affecting the heat preservation effect inside the greenhouse. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated agricultural greenhouse to solve the above-mentioned defects in the prior art.

[0005] An automated agricultural greenhouse includes a greenhouse frame, a greenhouse film, a dew removal mechanism, and a dirt cleaning mechanism. The greenhouse frame is multi-span and is divided into an upper raised surface and a side flat surface. The greenhouse film covers the greenhouse frame. A photosensitive sensor is arranged at the lower part of the greenhouse frame. The dew removal mechanism is installed at the side end of the greenhouse frame and is used for removing dew on the inner surface of the multi-span greenhouse. The dirt cleaning mechanism is arranged at the upper part of the greenhouse frame and above the greenhouse film, and is used for removing the light-blocking dust at the groove where the greenhouse films at the top of the multi-span greenhouse are connected.

[0006] Preferably, the dew removal mechanism includes a driving motor, a hollow bidirectional threaded mandrel, and a "V"-shaped sliding part. The driving motor is installed on the side end of the shed frame, and the output end of the driving motor is equipped with a driving wheel. The hollow bidirectional threaded mandrel is horizontally rotatably installed on the side end of the shed frame and is located below the driving motor. One end surface of the hollow bidirectional threaded mandrel is coaxially fixedly connected with a first driven wheel, and the first driven wheel is connected to the driving wheel through a transmission chain. Adjustable mounting brackets are symmetrically installed on the shed frame. The upper end of the mounting bracket is hinged with an inclined guide rod, and the lower end of the mounting bracket is hinged with a slotted diversion plate. The other ends of the guide rod and the slotted diversion plate are both hinged to a fixed frame. Water collecting troughs are symmetrically arranged on the inner side end of the shed frame. The fixed frame is installed in the middle of the upper end of the shed frame, and a water pump is also installed on the fixed frame. A circulation pipeline connected to the hollow bidirectional threaded mandrel is installed on the water pump. The sliding parts are symmetrically threadedly installed on the hollow bidirectional threaded mandrel. Liquid collecting rods are symmetrically installed on the sliding parts. Magnetic sliders are slidably arranged on the liquid collecting rods. Air channels are symmetrically formed on the sliding parts. Permanent magnet pistons attracted to the magnetic sliders are slidably arranged in the air channels. A follower telescopic rod is hinged to the side end of the magnetic slider, and the lower end of the follower telescopic rod is slidably arranged on the guide rod.

[0007] Preferably, the cleaning mechanism includes a mounting seat, a bidirectional screw, and a sliding seat. The mounting seat is installed on the upper part of the shed frame and is located at the groove where the top of the multi-span greenhouse film is connected. The bidirectional screw is horizontally rotatably installed on the mounting seat. One end of the bidirectional screw is coaxially fixedly connected with a second driven wheel, and the second driven wheel meshes with the transmission chain. The sliding seats are symmetrically threadedly arranged on the bidirectional screw, and a scraping part is detachably installed on the sliding seat.

[0008] Preferably, the hollow bidirectional threaded mandrel divides the internal space of the multi-span greenhouse into an upper layer with low humidity and a lower layer with high humidity.

[0009] Preferably, the lower end opening of the slotted diversion plate is matched with the water collecting trough.

[0010] Preferably, the first driven wheel, the hollow bidirectional threaded mandrel, the sliding part, and the liquid collecting rod are all made of metal.

[0011] Preferably, the scraping part is matched with the groove where the top of the multi-span greenhouse film is connected, and the scraping part is made of a non-rigid material.

[0012] Preferably, the photosensitive sensor is placed in the lower layer with high humidity.

[0013] The advantages of the present invention are as follows: the light intensity in the multi-span greenhouse is detected by a photosensitive sensor, and a dew removal mechanism is arranged at the side end of the shed, and a dirt cleaning mechanism is arranged at the upper part of the shed and above the shed film, and the output end of the driving motor drives the driving wheel to rotate, so that the sliding part on the hollow bidirectional threaded core rod slides back and forth horizontally, and the sliding part and the magnetic slider can scrape off the condensed water dew, and the permanent magnetic piston in the airway slides back and forth synchronously, and an airflow rushing toward the roof is intermittently formed at the port of the airway, and the condensed water dew is collected and the intermittent airflow is continuously supplied, so that the internal space of the multi-span greenhouse automatically forms a humidity stratification of a low-humidity upper layer and a high-humidity lower layer, which not only avoids condensation and reduces the light transmittance, but also does not affect the environmental humidity required for the growth of agricultural plants, and the top shed film under the low-humidity upper layer environment will not immediately condense again, so that the light transmittance can be sustained;

[0014] At the same time, the transmission chain also drives multiple driven wheels to rotate synchronously, and the bidirectional screw drives the scraper to slide back and forth in the groove path where the top of the greenhouse film is connected, so as to automatically scrape off the dust and snow in the groove where the top of the greenhouse film is connected, and further ensure the light transmission and heat preservation effect in the greenhouse.

Specific implementation mode

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0024] As Figures 1 to 7 shown, an automated agricultural greenhouse includes a shed frame 1, a shed film 2, a dew removal mechanism 3 and a cleaning mechanism 4. The shed frame 1 is arranged in multi-span and is divided into an upper raised surface and a side flat straight surface. The shed film 2 covers the shed frame 1. A photosensitive sensor 5 is arranged at the lower part of the shed frame 1. The dew removal mechanism 3 is installed at the side end of the shed frame 1 and is used for removing dew from the inner surface of the multi-span greenhouse. The cleaning mechanism 4 is arranged at the upper part of the shed frame 1 and above the shed film 2 and is used for removing the light-blocking dust at the groove where the tops of the shed films 2 of the multi-span greenhouse are connected.

[0025] In this embodiment, the dew removal mechanism 3 includes a driving motor 301, a hollow bidirectional threaded mandrel 302, and a "V"-shaped sliding part 303. The driving motor 301 is installed on the side end of the shed frame 1, and a driving wheel 304 is installed at the output end of the driving motor 301. The hollow bidirectional threaded mandrel 302 is horizontally rotatably installed on the side end of the shed frame 1 and is located below the driving motor 301. A first driven wheel 305 is coaxially and fixedly connected to the outer surface of the end of the hollow bidirectional threaded mandrel 302. The first driven wheel 305 is connected to the driving wheel 304 through a transmission chain 306. Adjustable mounting brackets 307 are symmetrically installed on the shed frame 1. An inclined guide rod 308 is hinged to the upper end of the mounting bracket 307, and a slotted diversion plate 309 is hinged to the lower end of the mounting bracket 307. The other ends of the guide rod 308 and the slotted diversion plate 309 are both hinged to a fixed frame 316. Water collecting troughs 310 are symmetrically arranged on the inner side end of the shed frame 1. The fixed frame 316 is installed in the middle of the upper end of the shed frame 1. A water pump 317 is also installed on the fixed frame 316. A circulation pipeline 318 connected to the hollow bidirectional threaded mandrel 302 is installed on the water pump 317. The sliding parts 303 are symmetrically threadedly installed on the hollow bidirectional threaded mandrel 302. Liquid collecting rods 311 are symmetrically installed on the sliding parts 303. Magnetic sliders 312 are slidably arranged on the liquid collecting rods 311. Air channels 313 are symmetrically formed on the sliding parts 303. Permanent magnet pistons 314 attracted to the magnetic sliders 312 are slidably arranged in the air channels 313. A follower telescopic rod 315 is hinged to the side end of the magnetic slider 312. The lower end of the follower telescopic rod 315 is slidably arranged on the guide rod 308.

[0026] In this embodiment, the cleaning mechanism 4 includes a mounting seat 41, a bidirectional screw 42, and a sliding seat 43. The mounting seat 41 is installed on the upper part of the shed frame 1 and is located at the groove where the top of the multi-span greenhouse film 2 is connected. The bidirectional screw 42 is horizontally rotatably installed on the mounting seat 41. A second driven wheel 44 is coaxially and fixedly connected to the end of the bidirectional screw 42. The second driven wheel meshes with the transmission chain 306. The sliding seats 43 are symmetrically threaded on the bidirectional screw 42. A scraping member 45 is detachably installed on the sliding seat 43.

[0027] It should be noted that the model of the photosensitive sensor 5 is LXD / GB5-A1DPZ. The driving motor 301 is a servo motor and is electrically connected to the photosensitive sensor 5. Thrust settings are provided in the middle of both the hollow bidirectional threaded mandrel 302 and the bidirectional screw 42.

[0028] In this embodiment, the hollow bidirectional threaded mandrel 302 divides the internal space of the multi-span greenhouse into an upper layer with low humidity and a lower layer with high humidity.

[0029] In this embodiment, the lower opening of the slotted diversion plate 309 is matched with the water collecting trough 310.

[0030] It is worth mentioning that the hollow double - threaded mandrel 302, the sliding part 303, the liquid - collecting rod 311, and the circulation pipeline 318 are all made of beryllium copper with good heat - conduction effect. The port of the circulation pipeline 318 penetrates through the first driven wheel 305 and is rotationally connected to the hollow double - threaded mandrel 302 outside the greenhouse. The lower end of the sliding part 303 is open - ended and is matched with the slotted flow - guiding plate 309 directly below.

[0031] In this embodiment, the scraping part 45 is matched with the groove at the top of the multi - span greenhouse film 2, and the scraping part 45 is made of non - rigid material.

[0032] In addition, the photosensitive sensor 5 is placed in the lower layer with high humidity.

[0033] Working process and principle: During the use of the present invention, first, according to the uplift specification at the upper end of the shed frame 1 and the thickness of the greenhouse film 2, a scraping part 45 adapted to the groove at the top of the greenhouse film 2 is selected and installed on the sliding seat 43. Then, the photosensitive sensor 5 detects the light intensity in the multi - span greenhouse. When the light intensity is lower than the set light intensity suitable for agricultural planting in the greenhouse, it proves that there is dew condensation inside the film, or snow or dust adhesion outside the film.

[0034] At this time, the driving motor 301 and the water pump 317 are automatically started. The output end of the driving motor 301 drives the driving wheel 304 to rotate, which drives the first driven wheel 305 and the second driven wheel 44 to rotate synchronously through the transmission chain 306. The rotation of the first driven wheel 305 drives the hollow double - threaded mandrel 302 to rotate, and then drives the two sliding parts 303 on the hollow double - threaded mandrel 302 to slide horizontally towards each other until the two sliding parts 303 slide to the thrust position in the middle of the hollow double - threaded mandrel 302. Then, the driving motor 301 is reversed to make the two sliding parts 303 on one hollow double - threaded mandrel 302 slide horizontally back and forth.

[0035] During this process, the water pump 317 drives the water stored in the circulation pipeline 318 to circulate. The low temperature outside the greenhouse will be conducted to the internal stored water through the circulation pipeline 318 outside the greenhouse, and then conducted to the hollow double - threaded mandrel 302, the sliding part 303, and the liquid - collecting rod 311 in the greenhouse through the circulating water, and dew condensation will form on them.

[0036] During the sliding of the sliding part 303, the water dew condensed on the hollow double - threaded mandrel 302 is scraped off. And the follower telescopic rod 315 on the liquid - collecting rod 311 slides synchronously along the obliquely - arranged guide rod 308, so that the magnetic slider 312 scrapes off the water dew condensed on the liquid - collecting rod 311. The scraped water dew flows into the slotted flow - guiding plate 309 directly below through the opening at the lower end of the sliding part 303, and is then collected into the water - collecting tank 310 along the slotted flow - guiding plate 309 in the oblique direction.

[0037] At the same time, the reciprocating sliding of the magnetic slider 312 also drives the permanent magnet piston 314 in the airway 313 to slide reciprocally synchronously, and an airflow rushing toward the roof is intermittently formed at the port of the airway 313. The collection of condensed water and the continuous supply of intermittent airflow make the internal space of the multi-span greenhouse form a humidity stratification of a low-humidity upper layer and a high-humidity lower layer, which not only avoids condensation to reduce light transmittance but also does not affect the environmental humidity required for crop growth.

[0038] The transmission chain 306 also drives multiple driven wheels 44 to rotate synchronously, and the two-way screw 42 drives the scraper 45 to slide back and forth in the groove path connected to the top of the greenhouse film 2, thereby scraping off dust and snow in the groove connected to the top of the greenhouse film 2.

[0039] Based on the above, the present invention detects the light intensity in the multi-span greenhouse through a photosensitive sensor 5, and sets a dew removal mechanism 3 at the side end of the shed 1, and sets a cleaning mechanism 4 at the upper part of the shed 1 and above the shed film 2. The output end of the driving motor 301 drives the driving wheel 304 to rotate, so that the sliding part 303 on the hollow bidirectional threaded core rod 302 slides back and forth horizontally, and the sliding part 303 and the magnetic slider 312 can scrape off the condensed water dew, and the permanent magnetic piston 314 in the airway 313 slides back and forth synchronously, and an airflow rushing toward the roof is intermittently formed at the port of the airway 313. The collection of condensed water dew and the continuous supply of intermittent airflow make the internal space of the multi-span greenhouse automatically form a humidity stratification of a low-humidity upper layer and a high-humidity lower layer, which not only avoids condensation and reduces the light transmittance, but also does not affect the environmental humidity required for agricultural growth. In addition, the top shed film under the low-humidity upper layer environment will not immediately condense again, and the light transmittance can be sustained;

[0040] At the same time, the transmission chain 306 also drives multiple driven wheels 44 to rotate synchronously, and the bidirectional screw 42 drives the scraper 45 to slide back and forth in the groove path connected to the top of the greenhouse film 2, thereby automatically scraping off the dust and snow in the groove connected to the top of the greenhouse film 2, further ensuring the light transmission and heat preservation effect in the greenhouse.

[0041] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
