Detailed implementation manners

[0020] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1-3 , a spraying and irrigation device for a smart agricultural greenhouse, including a main frame 1. A first servo motor 101 is fixedly connected to the side wall of the main frame 1. The output end of the first servo motor 101 is fixedly connected to a threaded rod 102. A spraying assembly 2 is threadedly connected to the side wall of the threaded rod 102. The spraying assembly 2 is used for spraying and irrigating crops. A pressurizing assembly 3 is installed on the side wall of the main frame 1. The pressurizing assembly 3 is used to promote water to enter the inside of the spraying assembly 2. It further includes:

[0022] The spraying assembly 2 includes a connection block 201. The connection block 201 is threadedly installed on the outer wall of the threaded rod 102, and the connection block 201 extends into the inner cavity of the main frame 1 and is slidably connected to the main frame 1. A water inlet bucket 202 is fixedly connected to the bottom of the connection block 201, and the water inlet bucket 202 is communicated with the pressurizing assembly 3. Spraying rods 203 are fixedly connected to both sides of the water inlet bucket 202. A second servo motor 204 is fixedly connected to the inner wall of the connection block 201. The output end of the second servo motor 204 is fixedly connected to a rotating shaft 205;

[0023] A stirring plate 206 is fixedly connected to the side wall of the rotating shaft 205. A pressing plate 207 is threadedly connected to the side wall of the rotating shaft 205 above the stirring plate 206, and both sides of the pressing plate 207 extend into the inner cavity of the water inlet bucket 202;

[0024] It should be noted that: when the first servo motor 101 on the side wall of the main frame 1 is turned on, the first servo motor 101 drives the threaded rod 102 to rotate. Since the threaded rod 102 and the connection block 201 are threadedly connected, when the threaded rod 102 rotates, the connection block 201 can slide on the side wall of the threaded rod 102, that is, the connection block 201 can drive the water inlet bucket 202 to slide on the side wall of the threaded rod 102, and the reciprocating spraying and irrigation purpose is achieved by using the spraying rods 203. The pressurizing assembly 3 introduces external water flow into the inner cavity of the water inlet bucket 202. When the second servo motor 204 is turned on, the second servo motor 204 drives the stirring plate 206 to rotate, which will prevent impurities from settling and blocking the pipe orifice. Moreover, when the rotating shaft 205 rotates, the pressing plate 207 can press down to squeeze the water in the inner cavity of the water inlet bucket 202 out through the spraying rods 203, promoting the spraying effect.

[0025] Refer to Figures 1-3, the pressurizing assembly 3 includes a pressurizing box 301, a sliding block 302 is slidably connected to the inner wall of the pressurizing box 301, and a connecting column 303 is fixedly connected to the top of the sliding block 302;

[0026] The top of the connecting column 303 is fixedly connected with a collision block 304. A rotating column 305 is fixedly connected to the side wall of the threaded rod 102 outside the main frame 1. A spring 306 is fixedly connected between the sliding block 302 and the inner wall of the pressurizing box 301;

[0027] A connecting pipe 307 is fixedly connected between the pressurizing box 301 and the water inlet bucket 202. An external pipe 308 is fixedly connected to the side wall of the pressurizing box 301, and one-way valves are arranged in the inner cavities of the connecting pipe 307 and the external pipe 308;

[0028] It should be noted that when the threaded rod 102 drives the rotating column 305 to rotate, the rotating column 305 will collide with the collision block 304, and then squeeze the collision block 304 to slide downward, that is, the collision block 304 drives the sliding block 302 to slide downward through the connecting column 303. While the spring 306 is stretched, the sliding block 302 slides downward, and the water in the inner cavity of the pressurizing box 301 will be squeezed into the connecting pipe 307 and then introduced into the inner cavity of the water inlet bucket 202. When the collision block 304 moves away from the rotating column 305, under the action of the rebounding force of the spring 306, the sliding block 302 will return to its original position. At this time, a negative pressure will be generated in the pressurizing box 301, and then water will be pumped into the inner cavity of the pressurizing box 301 through the external pipe 308. In this way, the water inlet bucket 202 is filled with water through the connecting pipe 307 repeatedly. Since one-way valves are arranged in the inner cavities of the connecting pipe 307 and the external pipe 308, the connecting pipe 307 and the external pipe 308 are both unidirectional water passing, and water backflow can be avoided.

[0029] Refer to Figures 1-3 , the top of the collision block 304 is set to be arc-shaped, and the rotating column 305 and the collision block 304 can be fitted;

[0030] It should be noted that the setting of the collision block 304 facilitates the collision between the rotating column 305 and the collision block 304, and then squeezes the collision block 304 to slide, avoiding jamming between the collision block 304 and the rotating column 305.

[0031] Operation mode: Turn on the first servo motor 101 on the side wall of the main frame 1. The first servo motor 101 drives the threaded rod 102 to rotate. Since the threaded rod 102 is threadedly connected to the spraying assembly 2, when the threaded rod 102 rotates, the spraying assembly 2 can slide left and right on the threaded rod 102 to irrigate the crops in the greenhouse. When the threaded rod 102 drives the rotating column 305 to rotate, the rotating column 305 will collide with the collision block 304, and then squeeze the collision block 304 to slide downward, that is, the collision block 304 drives the sliding block 302 to slide downward through the connecting column 303. While the spring 306 is stretched, the sliding block 302 slides downward, squeezing the water in the inner cavity of the pressure box 301 into the connecting pipe 307 and then into the inner cavity of the water inlet bucket 202. When the collision block 304 moves away from the rotating column 305, under the action of the elastic force of the spring 306, the sliding block 302 will return to its original position. At this time, a negative pressure will be generated in the pressure box 301, and then water will be pumped into the inner cavity of the pressure box 301 through the external pipeline 308. In this way, the water inlet bucket 202 is filled with water through the connecting pipe 307 repeatedly. Since check valves are provided in the inner cavities of the connecting pipe 307 and the external pipeline 308, the connecting pipe 307 and the external pipeline 308 are both unidirectional water passages, which can prevent water from flowing back;

[0032] Turn on the second servo motor 204. The second servo motor 204 drives the stirring plate 206 to rotate, which will prevent impurities from settling and blocking the pipe orifice. Moreover, when the rotating shaft 205 rotates, the pressing plate 207 can press down to squeeze the water in the inner cavity of the water inlet bucket 202 out through the spraying rod 203, promoting the spraying effect.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
