Description

Technical Field

[0001] The utility model relates to the field of vegetable planting, in particular to a ventilation device for a vegetable planting greenhouse. Background Art

[0002] A vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It allows people to eat off-season vegetables. Generally, a vegetable greenhouse uses a bamboo or steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growth of vegetables inside, giving the greenhouse a good thermal insulation effect.

[0003] Vegetable greenhouses usually need to use fans for ventilation to prevent problems such as excessive temperature and humidity in the greenhouse. Usually, a dust net is installed at the air inlet port of the fan to block mosquitoes and large dust particles in the external environment. However, the filter is usually not easy to disassemble after installation. When the mesh of the filter is blocked, the air intake of the fan is reduced, which will subsequently affect the ventilation effect in the greenhouse and affect the growth of vegetables in the long run.

[0023] The following is combined with Figure 1-5 To further explain this application,

[0024] The embodiment of the present application discloses a ventilation device for a vegetable growing greenhouse. Figures 1 to 3 A ventilation device for a vegetable growing greenhouse comprises a shell 1, a dustproof plate 2 is fixedly connected to the inner wall of the shell 1, an induced draft fan 9 is fixedly installed on the inner wall of the shell 1, a heating module 4 is provided on the inner wall of the shell 1, a mounting box 3 is fixedly connected to the top of the shell 1, and a cleaning mechanism 5 is provided on the surface of the shell 1;

[0025] The cleaning mechanism 5 includes a brush plate 501, and there are two brush plates 501. The two brush plates 501 are both attached to the surface of the dustproof plate 2. One side of the brush plate 501 is fixedly connected to the connecting plate 502, and the surface of the shell 1 is fixedly connected to the support plate 503. The side opposite to the support plate 503 is fixedly connected to the guide rod 504. The surface of the guide rod 504 is used in conjunction with the inner cavity of the connecting plate 502. The surface of the guide rod 504 is sleeved with a spring 505. The two ends of the spring 505 are fixedly connected to the surface of the connecting plate 502. One side of the shell 1 is fixedly connected to a guide rail 507. The surface of the guide rail 507 is slidably connected to a slider 508. The surface of the slider 508 is fixedly connected to a connecting seat 509. One side of the connecting plate 502 is rotatably connected to a connecting rod 506, and the surface of the connecting rod 506 is rotatably connected to the connecting seat 509. The inner cavity of the brush plate 501 is fixedly connected to the top rod 6, and a transmission mechanism 8 is provided in the inner cavity of the installation box 3. The ventilation device for the vegetable planting greenhouse fixes the outer shell 1 and the installation box 3 in the reserved position of the greenhouse, and introduces fresh air from the outside into the greenhouse through the induced draft fan 9. After long-term use, the mesh of the dustproof plate 2 is blocked, and the transmission mechanism 8 and the top rod 6 cooperate to push a group of brush plates 501 downward to clean the upper half of the dustproof plate 2. While a group of brush plates 501 moves downward, they push the connecting rod 506, and the other end of the connecting rod 506 pushes the slider 508 to slide to one side along the surface of the guide rail 507. When the slider 508 slides to one side, it pulls another group of connecting rods 506, and the other end of the connecting rod 506 pulls another group of brush plates 501 to move upward to clean the lower half of the dustproof plate 2.

[0026] Reference Figures 1 to 3 The inner cavity of the installation box 3 is provided with an installation cavity 301, and the inner wall of the installation cavity 301 is fixedly connected with a sealing plate 302. The transmission mechanism 8 includes a driving motor 801, and the driving motor 801 is fixedly installed in the installation cavity 301. The output end of the driving motor 801 is fixedly connected with a cam 802. The surface of the cam 802 cooperates with the surface of the ejector rod 6. Through the provided cam 802 and the ejector rod 6, the driving motor 801 can drive the cam 802 to rotate. When the cam 802 rotates, the protruding part pushes the ejector rod 6 to drive the brush plate 501. When the two groups of brush plates 501 approach each other, the connecting plate 502 squeezes the spring 505, and the cam 802 continues to rotate. The spring 505 releases the elastic potential energy, causing the ejector rod 6 to reset and fit closely with the cam 802, thereby realizing the reciprocating motion of the brush plate 501 through the cooperation of the cam 802, the ejector rod 6 and the cleaning mechanism 5, thereby improving the cleaning effect of the dustproof plate 2 and ensuring the air intake and ventilation effect.

[0027] Reference Figure 1 and Figure 2 The surface of the shell 1 is fixedly connected to the limiting block 7, and the surface of the top rod 6 is used in conjunction with the inner cavity of the limiting block 7. Through the setting of the limiting block 7, the surface of the top rod 6 slides along the inner cavity of the limiting block 7, thereby improving the stability of the top rod 6.

[0028] Reference Figure 1 and Figure 4 The inner cavity of the installation box 3 is provided with a water storage cavity 303, and the surface of the installation box 3 is provided with an observation window 304. A water pump 305 is provided at the bottom of the installation box 3, and the input end of the water pump 305 is fixedly connected to the water storage cavity 303, and the output end of the water pump 305 is fixedly connected to a nozzle 306. The nozzle 306 is provided in the inner cavity of the shell 1. Through the provided water storage cavity 303, the interior of the installation box 3 can store cleaning water, and the amount of water in the water storage cavity 303 can be observed in real time through the observation window 304. The cleaning water in the water storage cavity 303 can be extracted by the water pump 305, and the extracted water is sprayed out from the inside of the shell 1 through the nozzle 306, and the dust in the mesh of the dustproof plate 2 is sprayed out, and the cleaning effect of the dustproof plate 2 is further improved in cooperation with the cleaning mechanism 5.

[0029] Reference Figure 1 A water injection pipe 307 is provided on one side of the installation box 3, and one end of the water injection pipe 307 is fixedly connected to the water storage cavity 303. Through the provided water injection pipe 307, cleaning water can be added to the water injection pipe 307.

[0030] Reference Figure 2 and Figure 5 The heating module 4 includes a mounting frame 401, which is fixedly connected to the inner wall of the outer shell 1. The inner wall of the mounting frame 401 is fixedly connected with a support rod 402. The surface of the support rod 402 is sheathed with a heating wire 403. Both ends of the heating wire 403 are fixedly connected to the inner wall of the mounting frame 401. Through the setting of the heating module 4, if the weather is cold and the temperature is too low, the air temperature entering the vegetable greenhouse is low, which may easily cause most plants to be unable to be cultivated in cold weather. The heating module 4 is installed on the inner wall of the outer shell 1 through the mounting frame 401, and the heating wire 403 is fixed to the inner wall of the mounting frame 401 through the support rod 402. The heating wire 403 generates heat, and the wind introduced by the induced draft fan 9 blows the heat into the greenhouse, thereby trying to ensure the ventilation effect while raising the temperature in the greenhouse.

[0031] Working principle: After long-term use, the mesh of the dustproof plate 2 is clogged, and the driving motor 801 is enabled to drive the cam 802 to rotate. When the cam 802 rotates, the protruding part pushes the push rod 6 to push a group of brush plates 501 downward to clean the upper part of the dustproof plate 2. While a group of brush plates 501 moves downward, it pushes the connecting rod 506. The other end of the connecting rod 506 pushes the slider 508 to slide to one side along the surface of the guide rail 507. When the slider 508 slides to one side, it pulls another group of connecting rods 506. The other end of the connecting rod 506 pulls another group of brush plates 501 to move upward to clean the lower part of the dustproof plate 2. When the two groups of brush plates 501 approach each other, the connecting plate 502 squeezes the spring 505, and the cam 802 continues to rotate. The spring 505 The elastic potential energy is released, so that the push rod 6 is reset and fits tightly with the cam 802, so that the reciprocating motion of the brush plate 501 is realized through the cooperation of the cam 802, the push rod 6 and the cleaning mechanism 5. The cleaning water in the water storage cavity 303 can be extracted by the water pump 305, and the extracted water is sprayed out from the inside of the shell 1 through the nozzle 306 to spray out the dust in the mesh of the dustproof plate 2. The cleaning effect of the dustproof plate 2 is further improved in cooperation with the cleaning mechanism 5. If the weather is cold and the temperature is too low, the air temperature entering the vegetable planting greenhouse is low, which may easily make most plants unable to be cultivated in cold weather. The electric heating wire 403 is activated to generate heat, and the wind introduced by the induced draft fan 9 blows the heat into the greenhouse, so as to increase the temperature in the greenhouse while ensuring the ventilation effect as much as possible.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
