Description

Technical Field

[0001] The present invention relates to the field of forestry and farmland irrigation, and particularly to a forestry and farmland irrigation watering system and an irrigation watering method. Background Art

[0002] In modern agricultural production, an effective irrigation system is crucial for ensuring the healthy growth of crops. Traditional irrigation methods such as flood irrigation and furrow irrigation, although simple and easy to implement, have problems such as serious waste of water resources and increased soil erosion. In recent years, the introduction of drip irrigation and sprinkler irrigation technologies has, to a certain extent, improved the utilization efficiency of water resources and reduced soil erosion. However, these systems usually require high initial investment and maintenance costs, and it is difficult to lay pipelines in forest lands or farmlands with complex terrains, which limits their wide application. Therefore, it is particularly important to develop an irrigation system that is both economical and efficient and adaptable to various terrains.

[0003] In the prior art, a large number of farmland irrigation watering systems and corresponding devices have also been disclosed. Among them, for example, the Chinese patent with the publication number CN112005858A discloses a farmland automatic irrigation and drainage system, which includes a main control system, a detection unit, a drip irrigation device, a sprinkler irrigation device, an electric three-way valve, an irrigation water pipe, a water supply system, and a seepage pipe. When in use, the detection unit monitors environmental parameters such as soil moisture, wind speed, and air humidity in real time, and selects appropriate irrigation methods according to these parameters, including drip irrigation and sprinkler irrigation.

[0004] However, in the process of using the above prior art for forestry and farmland irrigation watering, there are still the following deficiencies: 1. When planting crops in farmland, different crops require different intervals, and the irrigation spacing of the above prior art cannot be adjusted according to the crop spacing after the farmland plants are replaced. Therefore, when different-spacing crops need to be planted, the irrigation water pipes need to be replaced, increasing the workload.

[0005] 2. Although the above prior art can select appropriate irrigation methods according to environmental parameters through the detection unit, it cannot automatically adjust the water flow rate, and there is still a possibility of over-irrigating the crops, which may lead to problems such as root rot of the crops, causing losses. In addition, it will also cause waste of water resources.

[0006] Therefore, under the above-stated viewpoints, there is still room for improvement in the forestry and farmland irrigation watering means of the prior art. Summary of the Invention

[0007] To solve the above problems, the present invention provides a forestry and farmland irrigation watering system, which includes a water pump. The upper end of the water pump is connected to a water suction pipe, and the side of the water suction pipe away from the water pump is connected to a water storage tank.

Each group of slide rail grooves is equidistantly distributed with a plurality of them along the axial direction of the drip irrigation pipe. The slide rail grooves are opposite in position to the drip tube grooves and should communicate with each other; a sealing block for closing the drip irrigation groove is slidably arranged inside the slide rail groove. A pull rope is commonly arranged among the plurality of sealing blocks on the same side of the drip irrigation pipe, and a control member for driving the pull rope to control the movement of the sealing block is installed on the inner wall of the drip irrigation pipe.

[0011] As a preferred technical solution of the present invention, a receiving chute communicating with the drip irrigation groove is opened on one side of the slide rail groove away from the axis of the drip irrigation pipe. First sealing plates and second sealing plates slidably docked inside the receiving chute are installed at intervals on the side walls of the plurality of sealing blocks on the same side of the drip irrigation pipe.

[0012] As a preferred technical solution of the present invention, the lengths of the first sealing plate and the second sealing plate are both greater than the length of the sealing block, and the length of the first sealing plate on the side close to the irrigation pipe is less than the length of the second sealing plate on the side close to the irrigation pipe.

[0013] As a preferred technical solution of the present invention, the control member includes a sliding ring slidably connected to the inner wall of the drip irrigation pipe. The side of the sliding ring away from the irrigation pipe is connected to the pull rope.

[0014] As a preferred technical solution of the present invention, a sliding groove is opened at the upper end of the drip irrigation pipe. A sliding rod is connected to the outer wall of the sliding ring. The sliding rod slides in the sliding groove, and the sliding rod is located in the middle of the sliding ring.

[0015] As a preferred technical solution of the present invention, two sealing blocks on the side away from the sliding ring are commonly connected with a cross plate. The cross plate is located on the side of the sealing block away from the sliding ring. A pull rod is connected to the middle of the side of the cross plate away from the sealing block. A partition plate penetrates through the inner wall of the drip irrigation pipe. A through hole is opened on the side of the partition plate close to the cross plate. The pull rod slides in the through hole. A bottom plate that slides inside the drip irrigation pipe is connected to the side of the pull rod away from the sliding ring. A return spring is connected between the bottom plate and the partition plate.

[0016] As a preferred technical solution of the present invention, the control member further includes a receiving plate installed on the outer wall of the water storage tank near the water outlet pipe. A controller is installed at the upper end of the receiving plate. A steering gear is installed on the upper end of the drip irrigation pipe near the irrigation pipe.

[0020] S3: Adjust the irrigation interval: Control the flow rate of the water flowing out of the water outlet pipe and adjust the water outlet position of the drip irrigation pipe through the control component to achieve the purpose of precise irrigation of crops.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] First, the present invention uses a humidity detector to monitor the soil humidity in real time and transmits the data to the controller through an electrical signal. The controller automatically adjusts the opening and closing of the ball valve according to the soil humidity situation, thereby precisely controlling the water flow rate and avoiding over-irrigation. This automatic control not only prevents the problem of crop root rot caused by excessive water, but also effectively saves water resources.

[0023] Second, the present invention can adjust the water outlet position of the drip irrigation pipe according to the needs of planting different crops through the sealing block and the sealing plate. Through the operation of the control member, interval drip irrigation of the drip irrigation tank can be realized, adapting to the planting intervals of different plants, so as to directly carry out precise irrigation on the roots of plants. This design reduces the need to replace the drip irrigation pipe and reduces the preparation workload before planting.

[0024] Third, the present invention can quickly adjust the irrigation spacing of the drip irrigation pipe through the steering gear. When it is necessary to replace the planted crops, the spacing of the drip irrigation pipe can be quickly adjusted through the control of the steering gear, without manual adjustment one by one, which greatly saves manpower. At the same time, when irrigation is not needed, the drip irrigation tank can be completely closed, further saving water resources and reducing the maintenance workload.

Detailed implementation manners

[0035] The following will Figures 1 - 8 describe the embodiments of the present invention in detail with reference to the

[0036] The embodiment of the present application discloses a forestry farmland irrigation and watering system. It should be noted that the forestry farmland irrigation and watering system of the present application is mainly applied in the process of irrigating and watering the forestry farmland. In terms of technical effects, it can monitor the soil humidity in real time through the humidity detector 447, automatically adjust the opening and closing of the ball valve 32, thereby accurately controlling the water flow size, avoiding over-irrigation. Especially, it can adjust the water outlet position of the drip irrigation pipe 34 according to the needs of different crops. Through the operation of the control member 44, it can achieve the interval drip irrigation of the drip irrigation tank 35, adapt to the planting intervals of different plants, and directly conduct precise irrigation on the roots of plants. This design reduces the need to replace the drip irrigation pipe and reduces the preparation workload before planting. Further, this forestry farmland irrigation and watering system can also quickly adjust the irrigation spacing of the drip irrigation pipe 34 by starting the steering gear 446. When it is necessary to replace the planted crops, through the control of the steering gear 446, the spacing of the drip irrigation pipe can be quickly adjusted without manual adjustment one by one, greatly saving manpower.

[0037] Referring to Figure 1 and Figure 2 As shown, a forestry farmland irrigation and watering system includes a water pump 1. The upper end of the water pump 1 is connected to a water suction pipe 11. One side of the water suction pipe 11 away from the water pump 1 is connected to a water storage tank 2. The outer wall of the water storage tank 2 is connected to a drip irrigation device 3. A control component 4 for adjusting the drip irrigation spacing is installed in the drip irrigation device 3.

[0038] The drip irrigation device 3 includes a water outlet pipe 31 for communicating with the inside of the water storage tank 2. A ball valve 32 for controlling the water flow is installed in the water outlet pipe 31. One side of the water outlet pipe 31 away from the water storage tank 2 is connected to an irrigation pipe 33. A plurality of drip irrigation pipes 34 connected to it are installed on the outer wall of the irrigation pipe 33 away from the water outlet pipe 31. The control component 4 is located in the drip irrigation pipe 34.

[0039] In the specific implementation process, first start the water pump 1. The water pump 1 pumps the water in the well into the water storage tank 2. Subsequently, the water in the water storage tank 2 enters the irrigation pipe 33 through the water outlet pipe 31. The water in the irrigation pipe 33 is dispersed into a plurality of drip irrigation pipes 34 and then flows into the soil from the drip irrigation pipes 34. During this process, the control component 4 can automatically control the rotation of the ball valve 32 according to the humidity in the soil, thereby controlling the size of the water flow flowing out of the water outlet pipe 31, avoiding the root rot of crops and the waste of water resources caused by excessive irrigation of farmland. In addition, different crops require different plant intervals. Through the control component 4, the water outlet position of the drip irrigation pipe 34 can be adjusted to ensure that the roots of plants can be directly irrigated, further saving water resources and being applicable to a variety of crops.

[0040] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in order to adjust the irrigation interval of the drip irrigation pipe 34, based on this, in this embodiment, two groups of drip irrigation grooves 35 are symmetrically distributed along the axial direction of the outer wall of the drip irrigation pipe 34. Each group of drip irrigation grooves 35 has a plurality of them, and they are equidistantly distributed along the length direction of the drip irrigation pipe 34. The regulation assembly 4 includes two groups of slide rail grooves 41 symmetrically opened on the inner wall of the drip irrigation pipe 34. Each group of slide rail grooves 41 has a plurality of them equidistantly distributed along the axial direction of the drip irrigation pipe 34. The slide rail grooves 41 are opposite to the positions of the drip grooves and should be interconnected; a sealing block 42 for closing the drip irrigation groove 35 is slidably arranged inside the slide rail groove 41. A pulling rope 43 is commonly arranged among the plurality of sealing blocks 42 on the same side of the drip irrigation pipe 34, and a control member 44 for driving the pulling rope 43 to control the movement of the sealing block 42 is installed on the inner wall of the drip irrigation pipe 34.

[0041] Furthermore, in this embodiment, a receiving chute 45 communicating with the drip irrigation groove 35 is opened on the side of the slide rail groove 41 away from the axis of the drip irrigation pipe 34. A first sealing plate 46 and a second sealing plate 47 that are slidably docked inside the receiving chute 45 are installed at intervals on the side walls of the plurality of sealing blocks 42 on the same side of the drip irrigation pipe 34.

[0042] It should be noted that the lengths of the first sealing plate 46 and the second sealing plate 47 are both greater than the length of the sealing block 42, and the length of the first sealing plate 46 on the side close to the irrigation pipe 33 is less than the length of the second sealing plate 47 on the side close to the irrigation pipe 33; that is, when the second sealing plate 47 closes the drip irrigation groove 35 corresponding to its position, the first sealing plate 46 does not extend to the drip irrigation groove 35 corresponding to its position, so as to realize the interval closing of the plurality of drip irrigation grooves 35 on the drip irrigation pipe 34, so as to increase the drip interval distance of the drip irrigation pipe 34 and make the drip irrigation pipe 34 drip irrigate at intervals.

[0043] In the specific implementation process, the control member 44 drives the two pulling ropes 43 to move toward the side close to the irrigation pipe 33. The pulling ropes 43 drive the plurality of sealing blocks 42 connected to them to slide along the slide rail grooves 41. The plurality of sealing blocks 42 respectively drive the first sealing plate 46 and the second sealing plate 47 to move synchronously, so that the first sealing plate 46 and the second sealing plate 47 slide to the designated position in the receiving chute 45 to realize the adjustment of the irrigation interval of the drip irrigation pipe 34.

[0044] Before planting different crops, the interval of the drip irrigation tank 35 can be adjusted by the control member 44 first, so as to adapt to the planting of different crops; when planting new crops, there is no need to replace the drip irrigation pipe 34 suitable for the planting interval of the new crops, which reduces the workload during planting. In addition, when the plants no longer need to be watered, the control member 44 drives the two drawstrings 43 to move towards the side close to the irrigation pipe 33 again. The drawstrings 43 drive the sealing block 42, the first sealing plate 46 and the second sealing plate 47 to move synchronously, so that the second sealing plate 47 closes the drip irrigation tank 35 communicated with its receiving chute 45, and at the same time the first sealing plate 46 still closes the drip irrigation tank 35 communicated with its receiving chute 45, so that a plurality of drip irrigation tanks 35 are completely closed, and the water on their inner walls cannot flow out and thus watering is no longer carried out.

[0045] Referring to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in

[0046] In order to realize the automatic adjustment of the water flow size of the water outlet pipe 31 and the semi-automatic control of the watering interval of the drip irrigation pipe 34, based on this, in this embodiment, the control member 44 includes a sliding ring 441 slidably connected to the inner wall of the drip irrigation pipe 34. The side of the sliding ring 441 away from the irrigation pipe 33 is connected to the drawstring 43; a sliding groove 442 is opened at the upper end of the drip irrigation pipe 34. A sliding rod 443 is connected to the outer wall of the sliding ring 441, and the sliding rod 443 slides in the sliding groove 442. The sliding rod 443 is located in the middle of the sliding ring 441; a cross plate 48 is jointly arranged between the two sealing blocks 42 on the side away from the sliding ring 441. The cross plate 48 is located on the side of the sealing block 42 away from the sliding ring 441. The middle of the side of the cross plate 48 away from the sealing block 42 is connected with a pull rod 49. A partition plate 50 is fixedly installed on the inner wall of the drip irrigation pipe 34. A through hole 51 is opened on the side of the partition plate 50 close to the cross plate 48. The pull rod 49 slides in the through hole 51. The side of the pull rod 49 away from the partition plate 50 is connected with a bottom plate 52 slidably arranged in the drip irrigation pipe 34. A return spring 53 is connected between the bottom plate 52 and the partition plate 50.

[0047] It should be noted that the length of the sliding ring 441 is greater than that of the sliding groove 442. During the movement of the sliding ring 441, the outer wall of the sliding ring 441 always fits against the inner wall of the drip irrigation pipe 34 and seals the sliding groove 442, so that the water in the drip irrigation pipe 34 will not flow out from the sliding groove 442. The controller 445 adopted in this embodiment is a PLC controller in the prior art, and its working principle will not be elaborated here. It is mainly used to receive the result of the humidity detected by the humidity detector 447 and output a signal to the drive motor 448, so as to adjust the steering gear 446 and the ball valve 32. The steering gear 446 adopted in this embodiment is a prior art, and it is mainly used to control the swing of the articulated rod 449, so as to control the opening and closing of the drip irrigation tank 35. In this embodiment, the return spring 53 will apply an elastic force to the bottom plate 52 towards the side away from the partition plate 50, so that the bottom plate drives the pull rod 49, the cross plate 48 and the pull rope 43 to move synchronously, so that the drip irrigation tank 35 is opened again, and the irrigation interval of the drip irrigation pipe 34 is restored.

[0048] In the specific implementation process, the humidity detector 447 is used to detect the humidity in the soil, and the signal is transmitted to the controller 445 through electrical connection. The controller 445 controls the drive motor 448 to start through electrical connection. The output shaft of the drive motor 448 rotates to drive the ball valve 32 to rotate, so as to adjust the water flow rate of the water outlet pipe 31 and realize automatic water control. That is, it can prevent the roots of crops from rotting due to being soaked in water for a long time due to excessive water content in the soil, and can also play a role in saving water resources.

[0049] In addition, when planting new crops, the controller 445 controls the activation of the servo 446. The output end of the servo 446 rotates counterclockwise to pull the hinge rod 449 to move closer to the irrigation pipe 33. The hinge rod 449 drives the sliding rod 443 to slide within the sliding groove 442. At the same time, the sliding rod 443 drives the sliding ring 441 to slide synchronously within the drip irrigation pipe 34. The sliding ring 441 drives the sealing block 42, the first sealing plate 46, and the second sealing plate 47 to seal the drip irrigation groove 35 through two pull ropes 43, thereby adjusting the irrigation spacing of the drip irrigation pipe 34, eliminating the need to adjust each drip irrigation pipe 34 individually and saving workload. At the same time, when the pull rope 43 pulls the sealing block 42 to move, the two sealing blocks 42 on the side away from the sliding ring 441 drive the cross plate 48 to move synchronously closer to the irrigation pipe 33. The cross plate 48 drives the pull rod 49 and the bottom plate 52 to move synchronously. The pull rod 49 slides within the through hole 51, and the return spring 53 adaptively contracts under the extrusion of the bottom plate 52. When the irrigation interval of the drip irrigation pipe 34 needs to be restored, the servo 446 is activated. The output end of the servo 446 rotates clockwise to push the hinge rod 449 and the sliding ring 441 to move away from the irrigation pipe 33. At the same time, the bottom plate 52 moves away from the irrigation pipe 33 under the rebound of the return spring 53. The bottom plate 52 drives the pull rod 49 and the cross plate 48 to move synchronously. The cross plate 48 drives the two sealing blocks 42 on the side away from the sliding ring 441 to move synchronously. The two sealing blocks 42 drive the pull ropes 43, the first sealing plate 46, the second sealing plate 47, and other sealing blocks 42 to move synchronously away from the irrigation pipe 33, thereby driving the first sealing plate 46 and the second sealing plate 47 to reset, opening the drip irrigation groove 35, and restoring the irrigation spacing of the drip irrigation pipe 34, further saving workload and achieving semi-automatic control of the irrigation spacing of the drip irrigation pipe 34, greatly saving manpower.

[0050] In addition, the present invention also provides a forestry farmland irrigation method, including the following steps:

[0051] S1. First, start the water pump 1. The water pump 1 pumps the water in the water well into the water storage tank 2. Subsequently, the water in the water storage tank 2 enters the irrigation pipe 33 through the water outlet pipe 31. The water in the irrigation pipe 33 is dispersed into multiple drip irrigation pipes 34 and then flows into the soil from the drip irrigation pipes 34.

[0052] S2. Crop irrigation: The control member 44 drives the two pull ropes 43 to move closer to the irrigation pipe 33. The pull ropes 43 drive the multiple sealing blocks 42 connected to them to slide along the slide rail groove 41. The multiple sealing blocks 42 drive the first sealing plate 46 and the second sealing plate 47 to move synchronously, so that the first sealing plate 46 and the second sealing plate 47 slide to the designated position within the accommodation chute 45 to achieve the adjustment of the irrigation interval of the drip irrigation pipe 34.

[0053] Before planting different crops, the interval of the drip irrigation trough 35 can be adjusted by the control member 44 first to adapt to the planting of different crops. When planting new crops, there is no need to replace the drip irrigation pipe 34 suitable for the planting interval of the new crops, which reduces the workload during planting. In addition, when the plants no longer need to be watered, the control member 44 drives the two pull ropes 43 to move towards the side close to the watering pipe 33 again. The pull ropes 43 drive the sealing block 42, the first sealing plate 46 and the second sealing plate 47 to move synchronously, so that the second sealing plate 47 closes the drip irrigation trough 35 communicated with its receiving chute 45, and at the same time, the first sealing plate 46 still closes the drip irrigation trough 35 communicated with its receiving chute 45, so that the multiple drip irrigation troughs 35 are completely closed, and the water on their inner walls cannot flow out and watering is no longer carried out.

[0054] S3. Adjust the watering interval: The humidity detector 447 detects the humidity in the soil and transmits a signal to the controller 445 through electrical connection. The controller 445 controls the driving motor 448 to start through electrical connection. The output shaft of the driving motor 448 rotates to drive the ball valve 32 to rotate, realizing the adjustment of the water flow size of the water outlet pipe 31 and realizing automatic water control. That is, it can prevent the crops from rotting due to the excessive water content in the soil and keep the roots soaked in water for a long time, and can also play a role in saving water resources.

[0055] In addition, when planting new crops, the controller 445 controls the activation of the servo 446. The output end of the servo 446 rotates counterclockwise to pull the articulated rod 449 to move closer to the irrigation pipe 33. The articulated rod 449 drives the sliding rod 443 to slide within the sliding groove 442. At the same time, the sliding rod 443 drives the sliding ring 441 to slide synchronously within the drip irrigation pipe 34. The sliding ring 441 drives the sealing block 42, the first sealing plate 46, and the second sealing plate 47 to seal the drip irrigation groove 35 through two pull ropes 43, thereby adjusting the irrigation spacing of the drip irrigation pipe 34, eliminating the need to adjust each drip irrigation pipe 34 individually and saving workload. At the same time, when the pull rope 43 pulls the sealing block 42 to move, the two sealing blocks 42 on the side away from the sliding ring 441 drive the cross plate 48 to move synchronously closer to the irrigation pipe 33. The cross plate 48 drives the pull rod 49 and the bottom plate 52 to move synchronously. The pull rod 49 slides within the through hole 51, and the return spring 53 adaptively contracts under the extrusion of the bottom plate 52. When it is necessary to restore the irrigation interval of the drip irrigation pipe 34, the servo 446 is activated. The output end of the servo 446 rotates clockwise to push the articulated rod 449 and the sliding ring 441 to move away from the irrigation pipe 33. At the same time, the bottom plate 52 moves away from the irrigation pipe 33 under the rebound of the return spring 53. The bottom plate 52 drives the pull rod 49 and the cross plate 48 to move synchronously. The cross plate 48 drives the two sealing blocks 42 on the side away from the sliding ring 441 to move synchronously. The two sealing blocks 42 drive the pull ropes 43, the first sealing plate 46, the second sealing plate 47, and the other sealing blocks 42 to move synchronously away from the irrigation pipe 33, thereby driving the first sealing plate 46 and the second sealing plate 47 to reset, opening the drip irrigation groove 35, and restoring the irrigation spacing of the drip irrigation pipe 34, further saving workload and achieving semi-automatic control of the irrigation spacing of the drip irrigation pipe 34, greatly saving manpower.
