Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation devices, in particular to a quantitative drip irrigation device for moisturizing the roots of saplings. Background Art

[0002] In order to improve the survival rate of seedlings, drip irrigation devices are usually used to drip irrigate the roots when planting seedlings. Various drip irrigation devices have been proposed in the prior art. For example, a Chinese utility model patent with publication number CN213187537U proposes a drip irrigation bag for watering trees. The drip irrigation bag has an additional regulating valve to control the water output, thereby adjusting the water output for newly planted trees and old trees, and during drought and non-drought time periods (time periods such as seasonal differences). Each drip irrigation bag is equipped with two regulating valves, and each regulating valve is installed on a catheter of a certain length. In this way, one drip irrigation bag can drip irrigate two trees, thereby improving the bag utilization rate. The drip irrigation bag uses a multifunctional zipper, which can connect one bag to another or more bags on the left and right to increase the circumference, and can be extended indefinitely, so that it is not limited by the circumference of the tree trunk, and drip irrigation can be achieved for thick trees. However, the drip irrigation bag device is made of relatively soft materials. When filled with water, it exerts a strong squeezing force on the thin saplings. When the water pressure in the drip irrigation bag is unbalanced, the saplings are easily bent or pushed down, causing damage to the saplings. Therefore, the saplings are not practical. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a sapling root moisturizing quantitative drip irrigation device which adopts a hard shell to support the sapling branches, prevent the saplings from falling over, and can provide moisturizing quantitative drip irrigation for the roots of the saplings, and has good practicality.

The lower end of the drip irrigation spigot is a pointed end with a hole; when working, the softer fabric expands after being filled with water in the multiple hard shells, thereby increasing the water storage capacity. The multiple hard shells are arranged vertically around, and the multiple bottom plates are placed on the ground, and the multiple side plates are pressed against each other, which will not cause pressure on the saplings. In addition, the multiple hard shells support the saplings to prevent them from falling over. Multiple drip irrigation spigots are inserted into the soil around the saplings, so that the water stored in the multiple hard shells drips into the drip irrigation spigots through the quantitative valves and hoses. The soil at the roots of the saplings is humidified through the multiple drip irrigation spigots.

The end extends out from the bottom of the vertical pipe; the water pressure in the hard shell composed of the bottom plate and the two side plates presses the upper piston into the vertical pipe, so that the upper piston closes the upper end of the vertical pipe. At this time, water will not be discharged. When the bottom plate is placed on the ground, the screw is blocked by the ground, so that the screw pushes the vertical rod upward, so that the upper piston rises above the vertical pipe, and the lower piston closes the lower end of the vertical pipe. At this time, water enters the horizontal pipe through the upper end of the vertical pipe, and then drips into the drip irrigation insert through the hose.

At this time, the notch of the special-shaped piston is aligned with the hose, so that the water in the cross pipe is output through the notch of the special-shaped piston and the hose. When it rains, rainwater is collected into the water receiving trough through the upper port of the water collecting pipe. The gravity of the rainwater pushes the water receiving trough downward, so that the water receiving trough pushes the push rod downward through the connecting rod, so that the push rod pushes the cross bar to rotate, so that the notch of the special-shaped piston is staggered with the hose, so that the special-shaped piston closes the input end of the hose, and the drip irrigation stops at this time. After the rainwater in the water receiving trough evaporates, the torsion of the torsion spring resets the special-shaped piston, and the drip irrigation starts automatically at this time, which is practical.

DETAILED DESCRIPTION

[0019] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0020] Example 1

[0021] like Figures 1 to 5 As shown, a quantitative drip irrigation device for moisturizing the roots of saplings includes a fabric 3, a hose 5 and a drip irrigation cannula 6; it also includes a bottom plate 1, two side plates 2 and a quantitative valve 4. The bottom plate 1 and the side plates 2 are made of hard materials. The inside of the bottom plate 1 is inclined upward. The side plates 2 are vertically arranged on both sides of the bottom plate 1. The inner edges of the two side plates 2 are connected. The bottom plate 1 and the two side plates 2 form an open hard shell. The edge of the fabric 3 is connected to the outer edge of the bottom plate 1 and the outer edges of the two side plates 2. The fabric 3 closes the opening of the hard shell formed by the bottom plate 1 and the two side plates 2. The quantitative valve 4 is installed At the bottom of the base plate 1, the input end of the metering valve 4 is connected to the inside of the hard shell, the input end of the hose 5 is connected to the output end of the metering valve 4, and the output end of the hose 5 extends into the input end of the drip irrigation tube 6, and the lower end of the drip irrigation tube 6 is a pointed end with a hole; it also includes multiple barrel covers 7, and the tops of multiple side panels 2 are all provided with water inlets, and the barrel covers 7 are all screwed on the multiple water inlets; it also includes multiple handles 8, and the tops of multiple side panels 2 are all installed with handles 8; it also includes multiple moisturizing films 9, and the multiple moisturizing films 9 are laid on the ground, and the multiple moisturizing films 9 are padded under the base plate 1.

[0022] During operation, by setting a water inlet and a barrel cover 7, it is convenient to add water to the hard shell composed of the bottom plate 1 and the two side plates 2. The softer fabric 3 expands after being filled with water in the multiple hard shells, thereby increasing the water storage capacity. Multiple moisturizing films 9 are laid on the ground. By installing multiple handles 8, the portability and mobility of the drip irrigation device are improved, so that the multiple hard shells are arranged vertically around, and the multiple bottom plates 1 are placed on the moisturizing films 9. The multiple moisturizing films 9 separate the multiple bottom plates 1 from the ground, reducing ground evaporation, and making the multiple side plates 2 resist each other, which will not cause pressure on the seedlings. In addition, the multiple hard shells support the seedlings to prevent them from falling over. Multiple drip irrigation tubes 6 are inserted into the soil around the seedlings, so that the water stored in the multiple hard shells drips into the drip irrigation tubes 6 through the quantitative valves 4 and the hoses 5. The soil at the roots of the seedlings is humidified through the multiple drip irrigation tubes 6. By adjusting the opening and closing size of the quantitative valves 4, quantitative drip irrigation of the roots of the seedlings is achieved.

[0023] Example 2

[0024] like Figure 6 and Figure 7As shown, on the basis of Example 1, the metering valve 4 includes a vertical pipe 10, a horizontal pipe 11, a vertical rod 12, an upper piston 13, a lower piston 14 and a screw 15. The vertical pipe 10 is installed on the lower end surface of the base plate 1, and the upper end of the vertical pipe 10 extends into the top of the base plate 1. The input end of the horizontal pipe 11 is connected to the lower outer wall of the vertical pipe 10. The vertical pipe 10 is connected to the horizontal pipe 11. The vertical rod 12 is movably inserted in the vertical pipe 10. The diameter of the vertical rod 12 is smaller than the inner diameter of the vertical pipe 10. The upper end of the vertical rod 12 is installed with an upper piston 13. The lower end surface of the upper piston 13 is inclined. The lower end of the vertical rod 12 is installed with a lower piston 14. The upper piston 13 is in sliding contact with the upper part of the vertical pipe 10, and the lower piston 14 is in sliding contact with the lower part of the vertical pipe 10. The upper piston 13 and the lower piston 14 are respectively located above and below the horizontal pipe 11. The upper end of the screw 15 is rotatably threaded with the lower end of the vertical rod 12, and the lower end of the screw 15 extends out from the bottom of the vertical tube 10; it also includes a cross bar 16, a torsion spring 17, a special-shaped piston 18, a push rod 19, a connecting rod 20, a water collecting pipe 21 and a water receiving trough 22. The front end of the cross bar 16 is rotatably installed in the cross tube 11, and the two ends of the torsion spring 17 are respectively connected to the cross tube 11 and the cross bar 16. The front end of the cross bar 16 is installed with a special-shaped piston 18, and a notch is provided on the side wall of the special-shaped piston 18. The notch is opposite to the input end of the hose 5. One end of the push rod 19 is connected to the rear end of the cross bar 16, and the other end of the push rod 19 is rotatably connected to the lower end of the connecting rod 20. The water collecting pipe 21 vertically passes through the fabric 3 and the bottom plate 1, and the water receiving trough 22 is slidably installed in the water collecting pipe 21. The upper end of the connecting rod 20 is rotatably connected to the water collecting pipe 21.

[0025] The water pressure in the hard shell composed of the bottom plate 1 and the two side plates 2 presses the upper piston 13 into the vertical pipe 10, so that the upper piston 13 closes the upper port of the vertical pipe 10. At this time, water will not be discharged. When the bottom plate 1 is placed on the ground, the screw 15 is blocked by the ground, so that the screw 15 pushes the vertical rod 12 upward, so that the upper piston 13 rises above the vertical pipe 10, and the lower piston 14 closes the lower port of the vertical pipe 10. At this time, water enters the horizontal pipe 11 through the upper port of the vertical pipe 10, and then drips into the drip irrigation insert 6 through the hose 5. By rotating the screw 15, the length of the screw 15 extending out of the lower port of the vertical pipe 10 can be adjusted, thereby adjusting the size of the upper port of the vertical pipe 10 opened by the upper piston 13, thereby achieving quantitative adjustment of drip irrigation. During drought, the torsion force of the torsion spring 17 causes the cross bar 16 to drive the special-shaped piston 18 to remain stable. At this time, the notch of the special-shaped piston 18 is aligned with the hose 5, so that the water in the cross pipe 11 is output through the notch of the special-shaped piston 18 and the hose 5. When it rains, rainwater is collected into the water receiving trough 22 through the upper port of the water collecting pipe 21. The gravity of the rainwater pushes the water receiving trough 22 downward, so that the water receiving trough 22 pushes the push rod 19 downward through the connecting rod 20, so that the push rod 19 pushes the cross bar 16 to rotate, so that the notch of the special-shaped piston 18 is staggered with the hose 5, so that the special-shaped piston 18 closes the input end of the hose 5, and the drip irrigation stops at this time. After the rainwater in the water receiving trough 22 evaporates, the torsion force of the torsion spring 17 resets the special-shaped piston 18, and the drip irrigation starts automatically.

[0026] like Figures 1 to 7 As shown, the present invention is a quantitative drip irrigation device for moisturizing the roots of saplings. When it is working, first, the fabric 3 with a relatively soft material is filled with water in the multiple hard shells and then expands, thereby increasing the water storage capacity. Multiple moisturizing films 9 are laid on the ground, and multiple bottom plates 1 are placed on the moisturizing films 9. Multiple hard shells are arranged vertically around them, and multiple side plates 2 are pressed against each other, which will not cause pressure on the saplings. In addition, the multiple hard shells support the saplings to prevent them from falling over. Then, multiple drip irrigation tubes 6 are inserted into the soil around the saplings. Then, when the bottom plate 1 is placed on the ground, the screw 15 is blocked by the ground, so that the screw 15 pushes the vertical rod 12 upward, so that the upper piston 13 rises to the vertical pipe 1 0, the lower piston 14 closes the lower end of the vertical pipe 10. At this time, water enters the horizontal pipe 11 through the upper end of the vertical pipe 10, and then drips into the drip irrigation insert 6 through the hose 5. Finally, when it rains, rainwater is collected into the water receiving trough 22 through the upper end of the water collecting pipe 21. The gravity of the rainwater pushes the water receiving trough 22 downward, so that the water receiving trough 22 pushes the push rod 19 downward through the connecting rod 20, so that the push rod 19 pushes the cross bar 16 to rotate, so that the notch of the special-shaped piston 18 is staggered with the hose 5, so that the special-shaped piston 18 closes the input end of the hose 5, and the drip irrigation stops at this time. After the rainwater in the water receiving trough 22 evaporates, the torsion of the torsion spring 17 resets the special-shaped piston 18, and drip irrigation starts automatically.

[0027] The main functions achieved by this utility model are:

[0028] 1. The hard shell can support the sapling branches and prevent the saplings from falling over;

[0029] 2. It can provide quantitative drip irrigation for the roots of seedlings and adjust the quantitative size, which is very practical;
