Description

Technical Field

[0001] The invention relates to the technical field of cherry tree planting, in particular to a water and fertilizer spraying device for cherry trees. Background Art

[0002] Cherry tree water and fertilizer spraying devices are mostly used for watering and fertilizing cherry trees to improve the growth effect and fruit quality of cherry trees. It is usually divided into multiple stages of spraying. When spraying, water and fertilizer are evenly sprayed on the leaves, trunks and roots of cherry trees to meet the nutritional needs of trees in different growth periods. The fertilizer, water, position and range of each stage must be strictly controlled.

[0003] The patent with patent publication number CN112106508A discloses an automatic spraying device for pesticides, water and fertilizer for pest control of oil tea seedlings. The transmission device can drive the stirring rod to rotate, so as to stir the water and fertilizer in the water tank to make the water and fertilizer more uniform. While the stirring rod is rotating, the cleaning brush can also clean the water and fertilizer attached to the stirring rod to reduce waste. At the same time, the rotating crushing teeth can also crush the sediment at the bottom of the water tank to prevent problems such as agglomeration between materials.

[0004] The prior art has the following defects: The spraying direction and range cannot be adjusted: The water and fertilizer supply of cherry trees needs to be adjusted in the spraying direction and range according to the growth stage and physiological needs. For example, from the flowering period to the fruit setting period, cherry trees need sufficient water to support the opening of flowers and fruit setting. Fertilization and watering at this stage are mainly concentrated in the inner edge to the middle area of ​​the crown projection. During the fruit growth period, the fruit begins to swell and the nutritional needs increase. Fertilization and watering at this stage are mainly concentrated on the leaves of the entire crown, especially the leaves near the fruit, to enhance photosynthesis and improve the synthesis of organic matter. Therefore, a structure with adjustable spraying direction and range is needed to adapt to the water and fertilizer supply needs of cherry trees.

[0005] Uneven liquid distribution leads to uneven growth: In cherry tree planting areas, uneven liquid distribution will lead to uneven growth, which has a direct impact on fruit yield and quality. Some cherry trees may grow vigorously with lush branches and leaves, while others grow slowly, or even have yellow leaves and thin branches. As a result, the fruits in some areas may be larger and mature earlier, while the fruits in other areas are small and mature later, or even immature or of poor quality. Therefore, an adjustable capacity device can be set for each cherry tree to achieve the effect of uniform distribution and adjustable spraying amount. Summary of the invention

[0034] By controlling the reset wheel 621 to adjust the position of the three-sided ball valve 622, the liquid in the circulating water pipe 4 can be input into the controlled quantity liquid storage tank 67 through the liquid storage tank water pipe 69.

[0036] Specifically, the buoyancy of the hollow float 681 is greater than the rotational force of the steering valve 683, and the steering valve 683 can be driven to rotate through the lightweight connecting rod 682. The rack 685 on the sliding base 686 will slide on the sliding base 686, and through the engagement of the rack 685 and the gear ring 684, a one-way output is formed, so that the push rod 687 presses down the pressure plate 625 but does not reset.

[0037] By controlling the gradual increase of the water and fertilizer liquid level in the liquid storage tank 67, the hollow float 681 will rise with the increase of the liquid level. When the hollow float 681 rises, the light connecting rod 682 drives the steering valve 683 to rotate, and the gear ring 684 on the steering valve 683 drives the rack 685 to slide up and down on the sliding base 686, and the flow direction of the water and fertilizer in the circulating water pipe 4 is controlled through the flow direction regulating component 62.

[0045] By controlling the flipping flow tube 724 to flip in the sleeve 721 so that the clamping block 722 on the flipping flow tube 724 is clamped in the clamping groove 723 on the sleeve 721, the effect of adjusting the spraying direction can be achieved.

When the water and fertilizer in the circulating water pipe 4 enter the control liquid storage tank 67, the hollow float 681 will rise with the increase of the liquid level. When the hollow float 681 rises, it drives the steering valve 683 to rotate through the lightweight connecting rod 682. The gear ring 684 on the steering valve 683 drives the rack 685 to slide up and down on the sliding base 686, so that the push rod 687 squeezes the pressure plate 625 to rotate the rotating rod 624, and drives the three-sided ball valve 622 to rotate, so that the flow port 623 changes, the liquid storage tank water pipe 69 is closed, and the circulating water pipe 4 is unblocked. , so that the water and fertilizer in the circulating water pipe 4 flow to the next controlled liquid storage tank 67.

The control reset wheel 621 adjusts the position of the three-sided ball valve 622 so that the liquid in the circulating water pipe 4 can be input into the control liquid storage tank 67 through the liquid storage tank water pipe 69.

[0055] The fertilizer is stirred by the fertilizer stirring tank 3 and input into the fertilizer storage tank 2, and the water storage tank 1 and the fertilizer storage tank 2 provide water and fertilizer to the circulating water pipe 4; and two liquid level sensors are provided in the water storage tank 1 and the fertilizer storage tank 2 for detecting high water level and low water level.

At this time, the water and fertilizer in the controlled quantity liquid storage tank 67 are quantitative, avoiding the problem of uneven growth caused by uneven liquid diversion.

[0057] During spraying, the control valve 64 is opened, and the water and fertilizer flow through the spraying water pipe 63 to the spraying water supply pipe 71, and are sprayed downward by the adjustable nozzles 75 on the outer circle spraying rod 73 and the inner circle spraying rod 74 through the flip circulation pipe 724; when it is necessary to adjust the spraying direction upward, the flip circulation pipe 724 is controlled to flip in the sleeve 721, so that the block 722 on the flip circulation pipe 724 is stuck in the groove 723 on the sleeve 721, and the outer circle spraying rod 73 and the inner circle spraying rod 74 are respectively hinged to the corresponding fixing frame 76 by fixing bolts 77 to fix them, so as to adapt to the water and fertilizer supply needs of cherry trees at different stages, so as to improve the growth effect and fruit quality of cherry trees.

[0058] The area is divided into multiple plots according to the planting area, and each plot has a workstation.
