Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse planting spraying, and more specifically, to a greenhouse planting spraying device. Background Art

[0002] In existing greenhouse cultivation technology, the traditional way to replenish water for plants is mainly through irrigation. The limitation of this method is that its coverage area is not uniform enough, which often causes plants in some areas to get too much water, while other areas may lack sufficient water. This uneven water distribution is not conducive to the growth and development of plants, because it may cause some plants to overgrow, while others may grow slowly due to lack of water. In addition, the irrigation method is also affected by many uncontrollable factors, such as the accuracy of human operation, the direction and speed of water flow, etc., which may affect the effect of water replenishment.

[0003] In terms of spray devices, existing technologies generally use fixed equipment structures. This design limits the mobility and flexibility of the spray devices, making it difficult for them to provide comprehensive water to plants. Fixed devices may create blind spots in certain areas of the greenhouse, resulting in plants in these areas not getting enough water.

[0004] In terms of pipeline transportation, existing technologies usually use pipelines to transport water to atomizing nozzles for spraying. However, the internal structure of the pipelines in the existing technology is often relatively simple, and the flow rate of the transported water cannot be flexibly adjusted according to the characteristics of the plants in the current area. This means that when the plants need more water, the pipeline may not be able to provide sufficient water flow; and when the plants need less water, too fast a water flow may cause waste. This inflexible pipeline system not only affects the effective use of water, but may also cause unstable humidity control in the greenhouse, thereby affecting the growth environment of the plants.

The locking rod 7 is movably mounted on the outside of the adjusting tube 14, the guide plate 8 is rotatably sleeved on the outside of the adjusting tube 14, the rotary sleeve 9 is movably arranged at one end of the adjusting tube 14, the longitudinal groove 10 is arranged on one side of the rotary sleeve 9, the annular groove 11 is connected to the plurality of longitudinal grooves 10, the limit groove 12 is arranged on the fixed plate 13, the fixed plate 13 is fixedly connected to the outside of the adjusting tube 14, the adjusting sleeve 15 is fixedly arranged on one side of the sliding frame 6, the two ends of the baffle 16 are respectively connected to the sliding frame 6 and the rotating frame 17, the rotating frame 17 is movably arranged in the rotary sleeve 9, the fixed frame 18 is fixedly connected in the rotary sleeve 9, the tension spring 19 is connected to one side of the self-locking rod 7, the adjusting rod 20 is fixedly arranged on one side of the fixed frame 18, and the adjusting sleeve 15 and the adjusting rod 20 are movably connected through threads.

[0032] A connecting frame 21 is provided below the water storage tank 2 , and the atomizing nozzle 5 is installed below the connecting frame 21 .

[0033] A slide groove 22 is formed inside the adjusting tube 14 , and a slider 23 is formed outside the sliding frame 6 . The slider 23 is slidably installed in the slide groove 22 .

[0034] An anti-slip strip 24 is provided on the outer side of the rotary sleeve 9 , and a plurality of anti-slip strips 24 are fixedly connected to the outer side of the rotary sleeve 9 .

[0035] In this embodiment, when the device is used in a greenhouse, the water in the water tank 2 is first filled up by an external device, and then the external device is disconnected, and the two water pumps 3 are turned on synchronously. The water pump 3 will pump out the water in the water tank 2 through the delivery pipe 4 connected to the input end, and then the pumped water will be transported to each atomizing nozzle 5 through the delivery pipe 4 connected to the output end of the water pump 3, and then the atomizing nozzle 5 will spray the water in an atomized form. The connection frame 21 is provided with more atomizing nozzles 5 to achieve a wider range. When the input flow rate of the water pump 3 needs to be adjusted, the guide plate 8 is rotated in the corresponding direction. Due to the special structural design of the guide plate 8, when the guide plate 8 is rotated, the self-locking rod 7 will be gradually pushed to move outward, so that the self-locking rod 7 slides along the limit groove 12 and the longitudinal groove 10.

Since the adjusting sleeve 15 is movably sleeved on the outer side of the adjusting rod 20 through a thread, and the slider 23 and the slide groove 22 limit the sliding frame 6, then the adjusting sleeve 15 will drive the sliding frame 6 to slide along the adjusting rod 20, and the sliding frame 6 will drive the slider 23 to slide along the slide groove 22. The setting of the rotating frame 17 can prevent the spoiler 16 from being entangled together, and then the distance between the sliding frame 6 and the rotating frame 17 is shortened, so that the gap between the spoiler 16 is gradually reduced, thereby limiting the passing speed of water. After adjusting to a suitable flow rate, the rotating sleeve 9 is stopped, and the tension spring 19 will drive the self-locking rod 7 to reset, and then the self-locking rod 7 will slide along the limiting groove 12, and at the same time, the other end of the self-locking rod 7 will slide into the corresponding longitudinal groove 10, thereby effectively preventing the rotating sleeve 9 from rotating unnecessarily.

The design of the anti-slip strip 24 increases the friction force of the outer surface of the rotary sleeve 9, and then After that, the rotating sleeve 9 will drive the annular groove 11 to rotate, so that the self-locking rod 7 will slide relatively in the annular groove 11, and the rotating sleeve 9 will drive the fixed frame 18 arranged on the inner side to rotate, and then the fixed frame 18 will drive the adjusting rod 20 to rotate. Since the adjusting sleeve 15 is movably sleeved on the outer side of the adjusting rod 20 through a thread, and the slider 23 and the slide groove 22 limit the sliding frame 6, then the adjusting sleeve 15 will drive the sliding frame 6 to slide along the adjusting rod 20, and the sliding frame 6 will drive the slider 23 to slide along the slide groove 22. The setting of the rotating frame 17 can prevent the spoiler 16 from being entangled together, and then the distance between the sliding frame 6 and the rotating frame 17 is shortened, so that the gap between the spoiler 16 is gradually reduced, thereby limiting the passing speed of water, and after adjusting to a suitable flow rate, the rotating sleeve 9 is stopped, and the tension spring 19 will drive the self-locking rod 7 to reset, and then the self-locking rod 7 will slide along the limiting groove 12, and at the same time, the other end of the self-locking rod 7 will slide into the corresponding longitudinal groove 10, thereby effectively preventing the rotating sleeve 9 from rotating unnecessarily.

[0042] When it is necessary to move the spray device in the lateral direction, the first motor 33 is turned on synchronously, and the first motor 33 drives the lead screw 31 connected to the output end to rotate, so that the first sliding seat 32 slides along the lead screw 31, and the first slide bar 34 is set to make the first sliding seat 32 stably slide along the lead screw 31, and then the first sliding seat 32 will drive the spray device as a whole to move in the lateral direction. When it is necessary to move the spray device in the longitudinal direction, the second motor 29 installed on one side of the mounting frame 1 is turned on, and the second motor 29 drives the transmission wheel 28 and the connecting shaft 30 to rotate, thereby driving the two transmission wheels 28 to rotate synchronously, and then the transmission wheel 28 will drive the transmission chain 27 set on the outside to run, and then the transmission chain 27 will drive the second sliding seat 25 to slide along the second slide bar 26, and at the same time, the second sliding seat 25 will drive the first sliding seat 32 and the first slide bar 34 and other components to move in the longitudinal direction, thereby driving the spray device as a whole to achieve longitudinal movement, thereby realizing all-round atomization spraying.
