Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation devices, in particular to a drip irrigation system used in hilly citrus orchards. Background Art

[0002] Effective irrigation in hilly areas is an important factor in ensuring crop yields, improving the quality of cultivated land, supplementing high-quality cultivated land, and promoting the construction of ecological civilization. In recent years, the country has increased investment and development in irrigation in hilly areas, and agriculture has begun to develop in the direction of energy conservation, water conservation, and environmental protection. Citrus is the fruit tree with the largest cultivated area and the highest yield in Guangxi, accounting for more than half of Guangxi's fruit production. In 2022, Guangxi's citrus area was 9.4654 million mu and 18.0804 million tons. Guangxi's citrus production has ranked first in the country for 9 consecutive years. Guangxi is known as "eight mountains, one water, and one field". A large proportion of citrus is planted in hilly and mountainous areas. Especially for Guangxi with its unique karst landform style, due to its special terrain, some slopes are difficult to irrigate. Even if they can be irrigated, the slope of the terrain makes it difficult for the water in the pipe to flow out evenly. Even due to the reduction of water supply pressure, the water level inside the pipe laid on the slope will be reduced, and the drippers or drip holes at higher places may not even be able to discharge water. Ultimately, it is difficult to ensure the consistency of the overall irrigation volume, and uneven irrigation will cause the roots of citrus trees to not grow well.

[0003] Therefore, the utility model provides a drip irrigation system for a hilly citrus orchard to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3 As shown, the drip irrigation system for hilly citrus orchards provided by the utility model comprises a drip irrigation pipe 1, a plurality of drip holes 2 are evenly and equidistantly arranged at the bottom of the drip irrigation pipe 1, the drip irrigation pipe 1 is inclinedly arranged on the slope, an auxiliary tank body 3 is installed on the top of the drip irrigation pipe 1, the bottom of one end of the auxiliary tank body 3 is connected with the inside of the drip irrigation pipe 1, a floating valve body 4 is arranged at the bottom of one end of the auxiliary tank body 3, and an elastic supply port 5 is arranged at the other end of the auxiliary tank body 3 for replenishing the water volume inside the auxiliary tank body 3, the elastic supply port 5 is opened as the water pressure inside the drip irrigation pipe 1 increases, and the elastic supply port 5 is closed as the water pressure inside the drip irrigation pipe 1 decreases.

[0021] A water outlet 6 is provided at the bottom of one end of the auxiliary tank body 3, and two limit rods 7 are symmetrically arranged at both ends of the outer side of the water outlet 6, and the floating valve body 4 is slidably installed between the two limit rods 7. The water outlet 6 is used to supplement the drip irrigation pipe 1 with water inside the auxiliary tank body 3, so that the water pressure in the drip irrigation pipe 1 is maintained as stable as possible, the effect of uniform water discharge is achieved, and sufficient drip irrigation operation of citrus is ensured.

[0022] A conical block 8 is provided at one end of the top of the floating valve body 4, and the conical block 8 is arranged to fit the water outlet 6. The conical block 8 is used to block the water outlet 6. When the water pressure inside the drip irrigation pipe 1 is stable, as the water pressure rises, the floating valve body 4 moves upward, so that the conical block 8 blocks the water outlet 6 to prevent the water stored in the auxiliary tank 3 from flowing out.

[0023] A flow channel 9 is provided on each of the two limit rods 7, and the flow channel 9 is arranged horizontally; when the water supply pressure is reduced, or the water level inside the drip irrigation pipe 1 is reduced due to the influence of the slope of the drip irrigation pipe 1 arranged on the slope, the floating valve body 4 will slide to the bottom of the two limit rods 7. At this time, the flow channel 9 located above the conical block 8 is opened, and the supply water inside the auxiliary tank body 3 flows out from the flow channel 9 to the drip irrigation pipe 1 for replenishment.

[0024] A water inlet 10 is provided at the bottom of the other end of the auxiliary tank body 3, and an elastic chamber 11 is provided above the water inlet 10. Two sealing rods 12 are rotatably provided in the elastic chamber 11, and the two sealing rods 12 are connected to the inside of the elastic chamber 11 through a spring 14. The elastic supply port 5 is provided above the two sealing rods 12, and the two sealing rods 12 are connected to the side wall of the elastic chamber 11 through a rotating shaft 13, and the same-direction ends of the two sealing rods 12 fit closely to each other. When the water pressure inside the drip irrigation pipe 1 is sufficient, that is, when the water supply is stable, the sealing rod 12 will be opened due to the pressure of the water pressure, so that the water in the drip irrigation pipe 1 will enter the elastic supply port 5 to replenish the water volume of the auxiliary tank body 3, so that the water pressure in the subsequent drip irrigation pipe 1 is reduced. When the water supply is insufficient, the auxiliary tank body 3 is used to replenish the drip irrigation pipe 1.

[0025] The elastic chamber 11 is an L-shaped structure, and the elastic supply port 5 is arranged at the top of the elastic chamber 11 and is opened on the side wall of the auxiliary tank body 3. The elastic supply port 5 opened at the top can ensure that sufficient water is stored in the auxiliary tank body 3. Because the auxiliary tank body 3 is inclined, the elastic supply port 5 should be set as high as possible.

[0026] Working principle: When the water supply pressure decreases or the water level inside the drip irrigation pipe 1 arranged on the slope decreases due to the influence of the slope, the floating valve body 4 loses its buoyancy, and the water pressure in the auxiliary tank body 3 is greater than the pressure on the floating valve body 4 in the drip irrigation pipe 1, and it will slide down to the bottom of the two limit rods 7. At this time, the flow channel 9 located above the conical block 8 is opened, and the supply water inside the auxiliary tank body 3 flows out from the flow channel 9 to the drip irrigation pipe 1 for replenishment, so that the water pressure in the drip irrigation pipe 1 is maintained as stable as possible, and the effect of uniform water discharge is achieved, ensuring sufficient and uniform drip irrigation of citrus, so that the citrus root system can be well drip irrigated, and the depletion of citrus is avoided. When the water supply in the drip irrigation pipe 1 is restored, the water pressure in the drip irrigation pipe 1 begins to rise continuously. Since the increased water pressure is greater than the thrust of the spring 14 on the sealing rod 12, the sealing rod 12 will be flushed open by the water pressure, so that the water in the drip irrigation pipe 1 will continue to rise in the elastic chamber 11 and enter the elastic supply port 5 to replenish the auxiliary tank body 3 with water, so that the water pressure in the subsequent drip irrigation pipe 1 is reduced. When the water supply is insufficient, the drip irrigation pipe 1 is replenished with the auxiliary tank body 3, that is, when the water pressure in the drip irrigation pipe 1 is reduced, the spring 14 restores the sealing rod 12 to a closed state due to its reaction force, and blocks the elastic supply port 5 in the elastic chamber 11, preventing it from flowing out from the water inlet 10 and flowing out from the water outlet 6.
