Description

Technical Field

[0002] In modern agricultural production, an effective irrigation system is essential to ensure the healthy growth of crops. Although traditional irrigation methods such as flooding and furrow irrigation are simple and easy to use, they have serious problems such as waste of water resources and increased soil erosion. In recent years, the introduction of drip irrigation and sprinkler irrigation technology has improved the efficiency of water resource utilization and reduced soil erosion to a certain extent. However, these systems usually require high initial investment and maintenance costs, and it is difficult to lay pipelines in forests or farmlands with complex terrain, which limits their widespread application. Therefore, it is particularly important to develop an irrigation system that is both economical and efficient and adaptable to a variety of terrains.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 8 Embodiments of the present invention are described in detail.

[0032] 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 used in the process of forestry farmland irrigation and watering system. In terms of technical effect, it can monitor soil moisture in real time through the humidity detector 447, and automatically adjust the opening and closing of the ball valve 32, so as to accurately control the water flow size and avoid excessive irrigation, especially to adjust the water outlet position of the drip irrigation pipe 34 according to the needs of planting different crops. Through the operation of the control part 44, the interval drip irrigation of the drip irrigation trough 35 can be achieved to adapt to the planting intervals of different plants, so as to directly irrigate the roots of the plants accurately. This design reduces the need to replace the drip irrigation pipe and reduces the preparation workload before planting. Furthermore, the 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 change the crop to be planted, the spacing of the drip irrigation pipes can be quickly adjusted through the control of the steering gear 446, without the need to manually adjust them one by one, which greatly saves manpower.

[0033] Reference Figure 1 and Figure 2 As shown, a forestry farmland irrigation and watering system includes a water pump 1, a water pump pipe 11 is connected to the upper end of the water pump 1, a water storage tank 2 is connected to the side of the water pipe 11 away from the water pump 1, a drip irrigation device 3 is connected to the outer wall of the water storage tank 2, and a regulating component 4 for adjusting the drip irrigation spacing is installed in the drip irrigation device 3.

[0034] The drip irrigation device 3 includes a water outlet pipe 31 for connecting to 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, a watering pipe 33 is connected to the side of the water outlet pipe 31 away from the water storage tank 2, and a plurality of drip irrigation pipes 34 connected to the watering pipe 33 are installed on the outer wall of the watering pipe 33 away from the water outlet pipe 31, and the regulating component 4 is located in the drip irrigation pipe 34.

[0035] In the specific implementation process, the water pump 1 is first started, and the water pump 1 pumps the water in the well into the water tank 2. Then the water in the water tank 2 enters the irrigation pipe 33 through the 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. In this process, the regulating component 4 can automatically control the rotation of the ball valve 32 according to the humidity in the soil, so as to control the size of the water flow out of the outlet pipe 31, so as to avoid excessive irrigation water for farmland, which may cause root rot of crops and waste of water resources. In addition, different crops require different plant spacing. The water outlet position of the drip irrigation pipe 34 can be adjusted through the regulating component 4 to ensure that the roots of the plants can be irrigated directly, which further saves water resources and is applicable to a variety of crops.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in order to adjust the watering interval of the drip irrigation pipe 34, based on this, in the present embodiment, the outer wall of the drip irrigation pipe 34 is provided with two groups of drip irrigation grooves 35 symmetrically distributed along the axial direction thereof, each group of drip irrigation grooves 35 is multiple, and are evenly distributed along the length direction of the drip irrigation pipe 34, and the regulating component 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 is evenly distributed along the axial direction of the drip irrigation pipe 34, and the slide rail grooves 41 are opposite to the drip pipe grooves and should be connected to each other; a sealing block 42 for closing the drip irrigation groove 35 is slidably arranged inside the slide rail groove 41, a pull rope 43 is commonly arranged between the multiple sealing blocks 42 on the same side of the drip irrigation pipe 34, and a control member 44 for driving the pull rope 43 to control the movement of the sealing block 42 is installed on the inner wall of the drip irrigation pipe 34.

[0037] Furthermore, in this embodiment, a receiving slide groove 45 connected to 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, and the side walls of multiple sealing blocks 42 on the same side of the drip irrigation pipe 34 are installed with a first sealing plate 46 and a second sealing plate 47 that are slidably docked inside the receiving slide groove 45 at intervals.

[0038] 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 close to the irrigation pipe 33 is less than the length of the second sealing plate 47 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, thereby realizing the spaced closure of multiple drip irrigation grooves 35 on the drip irrigation pipe 34, so as to increase the drip irrigation pipe spacing distance of the drip irrigation pipe 34, so that the drip irrigation pipe 34 can be drip-irrigated at intervals.

[0039] During the specific implementation process, the control member 44 drives the two pull ropes 43 to move toward the side close to the irrigation pipe 33, and the pull ropes 43 drive the multiple sealing blocks 42 connected thereto to slide along the slide rail groove 41, and the multiple 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 specified position in the accommodating slide groove 45 to adjust the irrigation interval of the drip irrigation pipe 34.

[0040] Before planting different crops, the intervals of the drip irrigation troughs 35 can be adjusted by the control member 44 to adapt to the planting of different crops; when planting new crops, there is no need to replace the drip irrigation pipes 34 suitable for the planting intervals of the new crops, which reduces the workload during planting. In addition, when the plants no longer need to be watered, the two pull ropes 43 are driven by the control member 44 to move toward the side close to the irrigation pipe 33, and 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 connected to its receiving chute 45, and at the same time, the first sealing plate 46 still closes the drip irrigation trough 35 connected to its receiving chute 45, so that multiple drip irrigation troughs 35 are completely closed, and the water on their inner walls cannot flow out and no irrigation is performed.

[0041] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in order to realize automatic adjustment of the water flow size of the water outlet pipe 31 and semi-automatic control of the irrigation spacing 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, and the sliding ring 441 is connected to the pull rope 43 away from the irrigation pipe 33. The upper end of the drip irrigation pipe 34 is provided with a sliding groove 442, and the outer wall of the sliding ring 441 is connected to a sliding rod 443, and the sliding rod 443 slides in the sliding groove 442, and the sliding rod 443 is located in the middle of the sliding ring 441; away from the sliding groove 442, the sliding groove 442 is provided with a sliding rod 443, and the sliding rod 443 is located in the middle of the sliding ring 441. A transverse plate 48 is commonly provided between the two sealing blocks 42 on one side of the ring 441. The transverse plate 48 is located on the side of the sealing block 42 away from the sliding ring 441. A pull rod 49 is connected to the middle of the side of the transverse plate 48 away from the sealing block 42. A partition 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 50 close to the transverse plate 48. The pull rod 49 slides in the through hole 51. A bottom plate 52 sliding in the drip irrigation pipe 34 is connected to the side of the pull rod 49 away from the partition 50. A return spring 53 is connected between the bottom plate 52 and the partition 50.

[0043] It should be noted that the length of the sliding ring 441 is greater than the length of the sliding groove 442. During the movement of the sliding ring 441, the outer wall of the sliding ring 441 is always in contact with the inner wall of the drip irrigation pipe 34, and the sliding groove 442 is sealed, so that the water in the drip irrigation pipe 34 will not flow out of the sliding groove 442; the controller 445 used in this embodiment is a PLC controller in the prior art, and its working principle is not repeated here. It is mainly used to receive the result of the humidity detector 447 monitoring the humidity 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 used in this embodiment is a prior art, which is mainly used to control the swing of the hinged rod 449, thereby controlling the opening and closing of the drip irrigation groove 35. In this embodiment, the reset spring 53 applies an elastic force to the bottom plate 52 away from the partition 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 groove 35 is opened again, and the irrigation interval of the drip irrigation pipe 34 is restored.

[0044] In the specific implementation process, the humidity in the soil is detected by the humidity detector 447, and the signal is transmitted to the controller 445 through the electrical connection. The controller 445 controls the start of the drive motor 448 through the electrical connection, and the output shaft of the drive motor 448 rotates, thereby driving the ball valve 32 to rotate, so as to adjust the water flow size of the outlet pipe 31 and realize automatic water control, which can prevent the roots of crops from rotting due to excessive moisture content in the soil due to long-term immersion in water, and can also play a role in saving water resources.

The reset spring 53 shrinks adaptively under the squeezing of the bottom plate 52; when the irrigation interval of the drip irrigation pipe 34 needs to be restored, the steering gear 446 is started, and the output end of the steering gear 446 rotates in the same direction 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 reset spring 53, and 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 away from the side of the sliding ring 441 to move synchronously.

In addition, when the plants no longer need to be watered, the two pull ropes 43 are driven by the control member 44 to move toward the side close to the irrigation pipe 33, and 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 connected to its receiving chute 45, and at the same time, the first sealing plate 46 still closes the drip irrigation trough 35 connected to its receiving chute 45, so that multiple drip irrigation troughs 35 are completely closed, and the water on their inner walls cannot flow out and no irrigation is performed.
