Description

Technical Field

[0002] As an important part of agricultural production, irrigation management is crucial during the growth and development of fruit trees. Traditional irrigation methods, such as manual watering or ground flooding, have problems such as water waste, uneven irrigation, and high labor intensity. With the development of modern agricultural technology, fruit tree drip irrigation technology has emerged. With its advantages of water saving, high efficiency, and easy management, it has gradually become the mainstream method of orchard irrigation. However, a single drip irrigation method may not be able to meet the comprehensive and uniform irrigation needs of fruit trees in some cases. Especially when it is necessary to quickly replenish the water of fruit trees or to prevent and control diseases and pests, the spray function is particularly important. It can not only replenish water for the leaves of fruit trees, but also increase the humidity of the fruit tree planting environment, thereby creating a good growth environment for the growth of fruit trees.

[0003] Most of the current drip irrigation equipment is placed on the surface and is easily affected by the environment and human factors, resulting in rupture or damage. If the staff cannot detect abnormalities in the pipeline in time, the roots of the fruit trees will not receive sufficient water. In addition, during the growth period, the roots of the fruit trees will continue to expand outward, and the drip irrigation heads are mostly fixed and cannot adapt to the growth and expansion of the roots of the fruit trees. Moreover, when the current irrigation equipment is used for a long time, its water-outlet components will age or become clogged, resulting in insufficient water output.

[0027] A water tank 2 is arranged inside the mobile box 1, and irrigation water is stored in the water tank 2. A bent pipe 4 is arranged on one side of the water tank 2. The bent pipe 4 is L-shaped, and its horizontal section is connected to the water tank 2, and the vertical section extends downward and is connected to the drip irrigation head 3. A through hole 9 is arranged on the bottom surface of the mobile box 1, and the drip irrigation head 3 is located in the through hole 9. When the mobile box 1 moves, the drip irrigation head 3 can drip water downward, so as to irrigate the roots of the fruit trees, ensuring that the roots of the fruit trees can receive sufficient water. A water pump 6 is also arranged on the water tank 2. The water pump 6 can pump out the water in the water tank 2 through the pumping pipe 7 and transport it to the spray head 5 on the top through the outlet pipe 8. The spray head 5 can spray water mist, so as to replenish water to the branches and leaves of the fruit trees. At the same time, the spraying of water mist can improve the temperature and humidity of the environment and provide a good environment for the growth of fruit trees.

[0028] During long-term use, the pipes and the drip irrigation heads 3 will age or become clogged, affecting the normal water output. Therefore, it is necessary to regularly check whether the water output of the drip irrigation heads 3 is normal. When no irrigation is performed, the hydraulic rod 10 can drive the water tank 2 to rise as a whole, and drive the drip irrigation heads 3 to rise to the inside of the mobile box 1 through the bending tube 4, and then start the electric slide 11. The electric slide 11 can drive the force plate 15 to move to the bottom of the drip irrigation head 3 through the sliding plate 12. At this time, the drip irrigation head 3 can be started, and the drip irrigation head 3 will drip. Water flows onto the stress-bearing plate 15, and the bottom surface of the stress-bearing plate 15 is connected to the pressure sensor 13 through the pressure spring 14. When water drops onto the stress-bearing plate 15, pressure is generated on the stress-bearing plate 15. The main control unit 19 can convert the pressure data collected by the pressure sensor 13 into the water output of the drip irrigation head 3, so as to judge whether the water output of the drip irrigation head 3 is normal. When the drip irrigation head 3 is abnormal, it can be repaired, maintained or replaced in time to avoid the drip irrigation head 3 having too little water output and being unable to provide sufficient nutrients for the roots of the fruit trees.

[0029] For the drip irrigation head 3, its built-in regulating valve can adjust its water output, and the main control unit 19 can send a control signal to the drip irrigation head 3 to select different water outputs to suit different fruit trees. Therefore, when the drip irrigation head 3 is self-checked, its multiple water outputs can be tested. After the previous test is completed, the main control unit 19 can drive the electric slide 11 to drive the force-bearing plate 15 to move back through the sliding plate 12. During the movement, the force-bearing plate 15 will pass under the scraper bar 17 and the water-absorbing sponge 18, wherein the scraper bar 17 can scrape off the water on the force-bearing plate 15 detected last time, and the water-absorbing sponge 18 can absorb the remaining water on the force-bearing plate 15 to ensure that the force-bearing plate 15 is in a dry state, and then the force-bearing plate 15 can be moved back to the bottom of the drip irrigation head 3 for re-testing to avoid the presence of moisture on the force-bearing plate 15 affecting the detection process.

[0030] Preferably, it also includes off-road wheels 20 and handrail push rods 21, wherein the off-road wheels 20 are arranged on the bottom surface of the moving box 1, and the handrail push rods 21 are arranged on the side walls of the moving box 1.

[0031] The handrail push rod 21 can be used to push the mobile box 1 to move under the drive of the off-road wheels 20, so as to facilitate drip irrigation and spray irrigation for fruit trees in different positions. The off-road wheels 20 can be used on the rugged roads in the orchard, and at the same time provide good shock absorption performance to prevent the mobile box 1 from excessive shaking or even tipping over during movement.

[0032] Preferably, the self-checking mechanism further includes a limiting cylinder 22 , which is disposed on the top surface of the sliding plate 12 , the pressure sensor 13 is disposed in the limiting cylinder 22 , and the bottom end of the pressure spring 14 extends into the limiting cylinder 22 and is connected to the pressure sensor 13 .

[0033] When the force-bearing plate 15 moves due to external force, the pressure spring 14 will be stretched or compressed along the limiting cylinder 22. The limiting cylinder 22 can limit the pressure spring 14 to prevent the pressure spring 14 from undergoing irregular deformation. At the same time, when the scraper 17 and the absorbent sponge 18 clean the force-bearing plate 15, the problem of excessive downward movement of the force-bearing plate 15 leading to unclean cleaning can be avoided.

[0034] Preferably, the water outlet pipe 8 includes a telescopic tube 23 and a mounting tube 24, the mounting tube 24 passes through the bottom surface of the mobile box 1, the spray head 5 is arranged on the top surface of the mounting tube 24, the top end of the telescopic tube 23 is connected to the bottom end of the mounting tube 24, and the bottom end is connected to the water pump 6.

[0035] The installation pipe 24 is fixedly installed. When the hydraulic rod 10 drives the water tank 2 to rise and fall, the telescopic pipe 23 can be telescoped. When the water tank 2 is moving, the spray head 5 and the installation pipe 24 are stationary.

The weighing sensor 28 is located on the inner bottom surface of the water receiving box 27. The main control unit 19 is electrically connected to the electric control car body 26 and the weighing sensor 28 respectively.

[0037] The spray head 5 can spray water in the form of water mist, and in long-term use, some positions of the spray head 5 may be blocked. In addition to the self-inspection of the drip irrigation head 3, the present invention can also perform self-inspection on the spray head 5. When performing the self-inspection, the electric control body 26 can move on the fixed ring 25, thereby driving the water receiving box 27 to move to different positions, wherein the number of the electric control body 26 and the water receiving box 27 is at least 2, and can be moved to different positions below the spray head 5. When the spray head 5 sprays water mist, the water mist will enter the water receiving box 27. After spraying for a period of time, the water volume in the water receiving box 27 is collected by the weighing sensor 28 to determine whether the spray volume at different positions of the spray head 5 is consistent. When the spray volume is inconsistent, repair and maintenance can be carried out in time.

[0038] Preferably, the self-inspection mechanism also includes a raised platform 29, an electric push rod 30 and a sealing cover 31.

The sealing cover 31 is located above the outside of the moving path of the water receiving box 27, and the main control unit 19 is electrically connected to the electric push rod 30.

[0039] When the fruit trees are normally irrigated, in order to prevent the water from flowing into the water receiving box 27 and affecting the self-inspection process, a raised platform 29 is set on the top of the movable box 1. The electric push rod 30 set on the raised platform 29 can drive the sealing cover 31 to move. When the water receiving box 27 moves to the side of the raised platform 29, the sealing cover 31 can move to the top of the water receiving box 27 and seal the water receiving box 27 to prevent water from entering the water receiving box 27.
