Description

Technical Field

[0002] Grapes belong to the Vitaceae family. Grapes are tall, twining vines with bald or slightly wooly young stems. The leaves are papery, oval or round. Grapes have high requirements for water, and strict control of soil moisture is a prerequisite for growing good grapes. Grapes require more water in the early stages of growth or during the vegetative growth period. Grape irrigation determines whether the grapes can grow normally.

[0003] At present, the main irrigation methods for grape cultivation are flood irrigation and drip irrigation. The flood irrigation method has a large evaporation rate, resulting in serious waste of water resources. The drip irrigation method is to connect the sprinkler to the irrigation system for use. The installation method is to hang it on a bracket or plug it into the pre-buried pipeline on the ground. The field pipeline network is complex, and the water pressure at each node is uneven, resulting in different spray ranges of the sprinkler at each position. The drip irrigation effect is not ideal, and the existing sprinkler has weak high-pressure bearing capacity. If high-pressure water is connected at will, the internal structure of the sprinkler will be damaged. In addition, the existing sprinkler irrigation systems are all fixed installation structures, and the application scenarios are very limited. They can only be used for irrigation, not spraying. In addition, the existing sprinkler irrigation water resources are seriously wasted, and there are phenomena of over-irrigation and under-irrigation. Utility Model Content

A second spring 34 is arranged below the guide column 33. The second spring 34 is a compression spring. The lower end of the second spring 34 is elastically supported by an annular support ring 35 arranged on the inner wall of the inner drip tube 32. The upper end of the second spring 34 is elastically connected to the lower end of the guide column 33. The upper end of the guide column 33 passes through the bottom plate and the top plate of the water supply pipe 16 upward in sequence and then extends to the top of the water supply pipe 16. The guide column 33 is sealed and connected to the bottom plate and the top plate of the water supply pipe 16 respectively through a sealing ring. By installing the drip irrigation nozzle 3 on the water supply pipe 16, quantitative and precise irrigation of the root system of the grape crop can be achieved.

[0032] In this embodiment, please refer to the attached Figure 2 , 3A limit column 38 is arranged above the guide column 33, and the upper end of the limit column 38 is fixed to the bottom of the movable rod 36. Both ends of the movable rod 36 are guided and supported by a support 37 arranged on the water supply pipe 16. A horizontal guide hole is arranged on the support 37, and the movable rod 36 is horizontally penetrated in the guide hole. A guide driving mechanism 4 that can drive its lateral guide movement is arranged at one end of the limit column 38. The guide driving mechanism 4 includes a motor seat 41, a driving motor 42, a first connecting rod 43, and a second connecting rod 44. The motor seat 41 is fixed on the water supply pipe 16, and the motor seat A driving motor 42 is arranged on 41, and an output shaft of the driving motor 42 is fixedly connected to one end of a first connecting rod 43, and the other end of the first connecting rod 43 is hingedly connected to one end of a second connecting rod 44, and the other end of the second connecting rod 44 is hingedly connected to one end of a movable rod 36. The driving motor 42 drives the first connecting rod 43 to rotate, drives the second connecting rod 44 to swing up and down, and makes the movable rod 36 move back and forth laterally, so as to control the limit column 38 to drive the guide column 33 to move up and down, and control the on and off of the drip irrigation nozzle 3, and the structural reliability is good and the control method is simple.

[0033] In this embodiment, please refer to the attached Figure 2 , 3 The first inclined surface 331 is set at the upper end of the guide column 33, and the second inclined surface 381 matching the first inclined surface 331 is set at the lower end of the limiting column 38. During the horizontal movement of the guide column 33 to one side, the first inclined surface 331 presses down the second inclined surface 381, so that the limiting column 38 moves downward. The limiting column 38 moves downward to compress the second spring 34. At the same time, more through holes on the side wall of the inner dropper 32 are closed, reducing the amount of liquid entering the inner dropper 32 from the outer dropper 31. When the lower end of the limiting column 38 descends to the vicinity of the support ring 35, the through holes on the side wall of the inner dropper 32 will be completely closed, and the water from the outer dropper 31 cannot enter the inner dropper 32, so that the guide column 33 moves up and down to control the on and off of the drip irrigation nozzle 3. When irrigation is needed, the drip irrigation nozzle 3 needs to be opened, and when spraying is needed, the drip irrigation nozzle 3 is closed, and only the micro sprinkler 2 is working.

[0034] From the above technical solution, it can be seen that when using, please refer to the attached Figure 1-5First, the frame 1 and the water tank 13 are moved to the middle of one end of the farmland to be irrigated through the walking wheels 11, and start to move from one end of the farmland to the other end. The water pump 14 is started by the controller, and the water or pesticide in the water tank 13 enters the water pump 14 through the first water pipe 15. After being pressurized by the water pump 14, it enters the water supply pipe 16 through the second water pipe 17. The micro-spray water enters the outer nozzle 21 from the upper end of the outer nozzle 21, and then passes through the water hole on the side wall of the inner nozzle 22 to enter the inner nozzle 22, and then is discharged from the lower end of the inner nozzle 22 into the flow gap formed between the upper adjustment plate 24 and the lower adjustment plate 25, and is sprayed around along multiple flow channels 26 into tiny water droplets to wet the branches and leaves of the grape crops. When the water pressure in the micro-sprinkler 2 is too low, the first spring 27 automatically extends to move the adjustment rod 23 upward, driving the lower adjustment plate 25 to The micro sprinkler 2 moves upward, and the flow gap between the upper adjusting plate 24 and the lower adjusting plate 25 is reduced, so as to ensure that the water pressure of the micro sprinkler 2 remains unchanged and the spraying range will not be attenuated. At the same time, the irrigation water enters the outer drip tube 31 from the upper end of the outer drip tube 31, and the driving motor 42 drives the first connecting rod 43 to rotate, driving the second connecting rod 44 to swing up and down, and the second connecting rod 44 drives the movable rod 36 to move back and forth laterally. The limiting column 38 follows the movable rod 36 to move back and forth laterally, and drives the guide column 33 to move up and down. During the process, the guide column 33 moves up and down. When the guide column 33 moves upward, more through holes on the inner drip tube 32 will be connected. During the downward movement of the guide column 33, the through holes on the inner drip tube 32 will be connected until the through holes on the inner drip tube 32 are completely blocked, so as to realize that the drip irrigation sprinkler 3 can irrigate the grape crops intermittently according to the plant spacing during the on-off process.
