Description

Technical Field

[0001] The utility model relates to the technical field of tobacco field irrigation, and in particular to a tobacco field irrigation device based on the Internet of Things. Background Art

[0002] Tobacco field irrigation refers to providing an appropriate amount of water to the tobacco field during the tobacco planting process to meet the needs of tobacco growth. The main purpose of tobacco field irrigation is to maintain soil moisture and provide tobacco with sufficient water to promote normal growth and development of tobacco. In order to make tobacco grow better, it is usually necessary to apply a certain amount of fertilizer and water at different stages of tobacco growth.

[0003] At present, sprinkler irrigation is usually used for irrigating tobacco fields. However, in actual operation, the inventors found that the sprinkler irrigation method still has some shortcomings, specifically:

[0004] First, when using sprinkler irrigation, water is usually sprinkled around in a radial shape over a long distance. On the one hand, it is easy to cause water evaporation, resulting in a waste of water resources. In order to achieve the purpose of irrigation, it is necessary to continue to sprinkle for a long time, which further increases the consumption of water resources. On the other hand, the sprinkler water is usually sprinkled at a fixed position, which makes the water sprinkled unevenly. In this way, it is easy for water to accumulate and remain on some tobacco leaves, causing the growth of mold, which is not conducive to the growth of tobacco leaves. Furthermore, when fertilizers are mixed in the sprinkler water, after the fertilizer water accumulates and remains on some tobacco leaves, it will cause tobacco leaves to burn under the sunlight, which is even more unfavorable to the growth of tobacco leaves.

[0005] Secondly, when using sprinkler irrigation, tobacco farmers usually control the amount of water used for irrigation based on experience. This results in too much or too little water being used when irrigating tobacco fields. Too much water may cause tobacco roots to rot, while too little water may cause tobacco growth to slow down, both of which are not conducive to tobacco growth.

[0006] Therefore, based on the above-mentioned shortcomings, there is an urgent need to design a tobacco field irrigation device based on the Internet of Things. Utility Model Content

[0027] 2. The setting of the arc segment increases the spraying area of ​​the nozzle surrounding the tobacco plant.

In this way, the inclination of the nozzle can be adjusted by simply turning the adjusting bolt, which improves the convenience of using the sprinkler irrigation device.

[0029] 4. The setting of the sliding device facilitates the movement of the sprinkler device in the direction parallel to the ridges where the tobacco plants are planted, so that the sprinkler device can spray several tobacco plants on the same ridge one by one, which is conducive to the uniform growth of several tobacco plants on the same ridge; the setting of the ground rail facilitates the movement of the support frame in the direction perpendicular to the ridges where the tobacco plants are planted, so that the sprinkler device can spray tobacco plants on different ridges, which is conducive to the uniform growth of all tobacco plants in the tobacco field;

In this way, you can know whether the growth height of the tobacco plant reaches the expected height.

[0045] By using the tobacco field irrigation device of the present application, the nozzle 21 is moved close to the tobacco plant for spraying, which reduces the spray distance of water in the air, reduces the evaporation of water, and is beneficial to saving water resources. Furthermore, during the spraying process, the nozzle 21 surrounds the tobacco plant for spraying, which increases the uniformity of the spraying, avoids the retention of water on local tobacco leaves, reduces the reproduction of mold, and is beneficial to the growth of tobacco leaves. Furthermore, when spraying fertilizer water on the tobacco plant, the movable nozzle is aimed at the position of the stem of the tobacco plant close to the soil for spraying, which avoids the retention of fertilizer water on the tobacco leaves, and is beneficial to the roots of the tobacco plant for fertilizer. The absorption of water is beneficial to the growth of tobacco plants. Furthermore, the setting of the soil moisture wireless sensor can realize the remote measurement of soil moisture in the tobacco field. The soil moisture wireless sensor wirelessly transmits the soil moisture information to the irrigation cloud platform 4. The irrigation cloud platform 4 sets the threshold value according to the comparison of the soil moisture measurement value, and controls the opening and closing and the opening time of the solenoid valve 6 on the water pipe 3 through the first controller 5, so as to control the irrigation water consumption. In this way, the tobacco field is irrigated and managed through the tobacco field irrigation device based on the Internet of Things, which reduces manual work and improves the efficiency and accuracy of irrigation, which is beneficial to the growth of tobacco plants.

[0046] As a preferred technical solution of the present application, the sprinkler device 2 includes a first vertical rod 22, a first cross rod 23 and a second vertical rod 24, one end of the first vertical rod 22 is connected to the support frame 1, and the other end is rotatably connected to one end of the first cross rod 23, the other end of the first cross rod 23 is connected to one end of the second vertical rod 24, and the other end of the second vertical rod 24 is connected to the sprinkler 21;

[0047] A first motor 221 is fixedly connected to the bottom of the first vertical rod 22 , and a rotation shaft of the first motor 221 is fixedly connected to one end of the first cross rod 23 .

[0048] When spraying tobacco plants, the first vertical rod 22 is placed above the tobacco plants, and the second vertical rod 24 is placed on the side of the tobacco plants. The first vertical rod 22 is kept stationary, and the first motor 221 rotates to drive the first cross bar 23 to rotate, so that one end of the first cross bar 23 rotates around the first vertical rod 22, and the other end of the first cross bar 23 drives the second vertical rod 24 to rotate around the tobacco plants. The nozzle 21 on the second vertical rod 24 sprays water to spray the tobacco plants, thereby achieving surrounding spraying of the tobacco plants.

[0049] As a preferred technical solution of the present application, the water outlet end 212 includes an arc segment 2121 and a plurality of water outlet holes 2122 arranged on the arc segment 2121. The concave area of ​​the arc segment 2121 is used to accommodate the tobacco plants, and the water outlet holes 2122 are used to discharge water.

[0050] The arrangement of the arc segment 2121 increases the spraying area of ​​the nozzle 21 surrounding the tobacco plants. Thus, when the nozzle 21 sprays the tobacco plants, the nozzle 21 only needs to rotate at a smaller angle to achieve surrounding spraying of the tobacco plants, which is beneficial to improving the spraying efficiency.

[0051] As a preferred technical solution of the present application, the inclination angle of the nozzle 21 is adjustable; a U-shaped component 241 and an adjusting bolt 242 are provided below the second vertical rod 24, and a lug 213 is provided on the nozzle, and the adjusting bolt 242 passes through one side of the U-shaped component 241 and the lug 213 in sequence and is threadedly connected with the other side of the U-shaped component 241.

[0052] The height of the tobacco plants varies during different growth periods. By adjusting the inclination angle of the nozzle 21, the nozzle 21 can achieve an ideal spraying effect during spraying, which is beneficial to the growth of the tobacco plants at different periods. When the inclination angle of the nozzle 21 needs to be adjusted, the adjusting screw is loosened to make the U-shaped component 241 loose, the nozzle 21 is rotated to a suitable angle, and the adjusting bolt 242 is tightened to make the U-shaped component 241 clamp the nozzle 21, thereby ensuring the inclination angle of the nozzle 21. In this way, the inclination degree of the nozzle 21 can be adjusted by simply turning the adjusting bolt 242, thereby improving the convenience of using the sprinkler device 2.

[0053] As a preferred technical solution of the present application, the first vertical rod 22 includes a first fixed rod 222 and a first telescopic rod 223, the first fixed rod 222 is connected to the support frame 1, the first telescopic rod 223 can move vertically relative to the first fixed rod 222, and the bottom of the first telescopic rod 223 is connected to the first motor 221;

[0055] When the second motor 224 is rotated to make the flexible rope 225 wrap around the rotating shaft of the second motor 224, the first telescopic rod 223 compresses the spring 226, and the first telescopic rod 223 moves upward relative to the first fixed rod 222;

[0056] When the second motor 224 is rotated to make the flexible rope 225 release the winding around the rotating shaft of the second motor 224 , the first telescopic rod 223 moves downward relative to the first fixed rod 222 under the action of the spring 226 .

[0057] By adopting the above structure, the vertical movement of the first telescopic rod 223 relative to the first fixed rod 222 is realized. The vertical movement of the first fixed rod 222 drives the vertical movement of the nozzle 21. In this way, when spraying the tobacco plants, the nozzle 21 can rotate around the tobacco plants and move vertically along the tobacco plants to achieve all-round spraying of the tobacco plants, while avoiding local continuous spraying, which is beneficial to the growth of the tobacco plants.

The bottom of the base 71 is connected to the first fixing rod 222 and the second motor 224.

[0062] The third motor 73 drives the roller 72 to rotate, the rotation of the roller 72 drives the base 71 to move, the movement of the base 71 drives the first fixed rod 222 to move, the movement of the first fixed rod 222 drives the nozzle 21 to move, so as to spray different tobacco plants on the same ridge; in this embodiment, the third motor 73 and the roller 72 are driven by a turbine worm gear mechanism.
