Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to a water-saving drip irrigation device for agricultural planting. Background Technology

[0002] Drip irrigation is an irrigation method that uses pressurized water, filtered and then slowly and evenly dripped into the soil near plant roots through a network of pipes and emitters. It boasts high water utilization efficiency. Under drip irrigation conditions, the irrigation water moistens only part of the soil surface, effectively reducing ineffective evaporation of soil moisture. Simultaneously, because drip irrigation only wets the soil near the crop roots, other areas have lower soil moisture content, thus preventing weed growth. Drip irrigation systems do not generate surface runoff and allow for precise control of water depth, resulting in significant water savings.

[0003] When using drip irrigation, uneven flow rates from the drip heads are a common problem. The purpose of a drip irrigation system is to provide water evenly to plants. Uneven flow rates can lead to some plants receiving too much water while others suffer from dehydration, affecting the uniformity of crop growth. Uneven flow rates can also cause uneven soil moisture distribution, potentially leading to soil salinity accumulation or erosion. Excessive water can cause root diseases, while insufficient water can make plants more susceptible to drought stress and pests. The unevenness of drip irrigation is caused by the fact that the flow rate of the drip head is directly proportional to the pressure of the liquid flowing through the pipes. The reasons for changes in the internal pressure of the pipes include:

[0004] During drip irrigation, although a pre-filtration system is installed, minerals will still be present in the water. Over time, crystallization will occur, causing blockage of the drip head and resulting in uneven drip volume. Summary of the Invention

[0005] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The present invention provides a water-saving drip irrigation device for agricultural planting to solve the technical problems of differential pressure caused by pipeline interference and differential drip irrigation volume in different areas caused by drip head blockage.

[0006] The present invention adopts the following technical solution: an agricultural water-saving drip irrigation device, including a drip irrigation main pipe and drip irrigation branch pipes, and a drip irrigation mechanism for discharging water, and a control mechanism to prevent clogging of the drip irrigation mechanism. The drip irrigation mechanism includes a drip irrigation head, a seepage plate at the end of the drip irrigation head, an adjustment plate inside the seepage plate, a torsion spring between the adjustment plate and the seepage plate, a connecting rod inside the adjustment plate, a rotating plate at the end of the connecting rod, and a connecting bolt at the end of the drip irrigation head for connecting with the drip irrigation branch pipes.

[0007] Furthermore, water outlet holes are provided in the seepage plate and the control plate. In the initial state, the water outlet holes on the seepage plate and the control plate are misaligned, and the control plate rotates relative to the seepage plate. The connecting rod is located at the center of the rotating plate.

[0008] Furthermore, the rotating plate has a notch, and the notch is beveled.

[0009] Furthermore, the control mechanism includes a control box, a water outlet plate on one side of the control box, a mating plate on the inner side of the control box, the water outlet plate and the mating plate being arranged opposite each other, a partition plate in the middle of the control box, a flow channel in the partition plate, and a water outlet baffle plate slidably arranged at the corresponding position of the flow channel, a limiting spring block on the partition plate, an auxiliary plate and a floating plate on both sides of the partition plate respectively, the auxiliary plate being connected to the mating plate, a reset spring between the auxiliary plate and the control box, an abutting auxiliary block on the upper surface of the auxiliary plate, a connecting plate on the upper surface of the floating plate, a limiting block on one side of the connecting plate, an abutting spring block on the partition plate, the abutting spring block being located above the water outlet baffle plate, and a flow hole on the side wall of the control box, the flow hole being located above the floating plate in the initial state.

[0010] Furthermore, the water outlet plate and the mating plate are provided with two sets of seepage holes at their upper and lower ends. In the initial state, the seepage holes at the upper end of the water outlet plate overlap with the seepage holes at the upper end of the mating plate.

[0011] Furthermore, the bottom of the partition plate does not contact the inner surface of the control box.

[0012] Furthermore, the contact surfaces of the abutting block and the abutting auxiliary block are inclined surfaces.

[0013] Furthermore, the contact surface between the abutment block and the rotating plate is an inclined surface, and the notches on the abutment block and the rotating plate are positioned correspondingly.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] To address the clogging issues in existing drip irrigation heads due to their slow flow rate, long flow path, and small orifice diameter, this invention utilizes the combined action of the drip irrigation mechanism and control mechanism. This allows the water to accumulate pressure using its own gravity before drip irrigation begins. Furthermore, by improving the drip irrigation head, the drip holes are designed to achieve the drip irrigation effect through two relatively movable, offset orifice plates.

[0016] However, due to varying water quality, the clogging time of drip irrigation heads is not fixed. Therefore, it is necessary to determine whether the drip irrigation head is clogged. The judgment principle in this invention is based on whether there is a difference between the inflow and outflow water volumes. During continuous use, the inflow and outflow water volumes should be in a relatively balanced state. When the drip irrigation head is clogged, the outflow water volume will be less than the inflow water volume. When clogging occurs, the energy storage control mechanism will cause the cross-diameter of the water outlet holes of the seepage plate and the control plate in the drip irrigation mechanism to increase. This creates a relative pulling effect between the seepage plate and the control plate. At this time, the impurities filling the overlapping seepage plate and the control plate will become loose and the water outlet diameter will increase, making it easier to flush them out.

[0017] In summary, this drip irrigation device does not require an additional power source during use. Its energy storage utilizes the gravity of the water itself, and whether it is blocked is determined by subsequent triggering, which utilizes the difference between the water inflow and outflow and the buoyancy of the water to achieve the effect of automatically cleaning the seepage holes.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The following is combined with Figures 1 to 7As shown, this embodiment of the invention provides a water-saving drip irrigation device for agricultural planting, including a drip irrigation main pipe 1 and drip irrigation branch pipes, and a drip irrigation mechanism 2 for discharging water, and a control mechanism 3 to prevent clogging of the drip irrigation mechanism 2. The drip irrigation mechanism 2 includes a drip irrigation head 21, a seepage plate 22 at the end of the drip irrigation head 21, an adjustment plate 23 on the inner side of the seepage plate 22, a torsion spring between the adjustment plate 23 and the seepage plate 22, a connecting rod 24 on the inner side of the adjustment plate 23, a rotating plate 313 at the end of the connecting rod 24, and a connecting bolt at the end of the drip irrigation head 21 for connecting to the drip irrigation branch pipe 11.

[0034] When in operation, the drip irrigation device does not require an additional power source. The energy storage utilizes the gravity of the water itself, and the determination of whether it is blocked is based on subsequent triggering, which utilizes the difference between the water inflow and outflow and the buoyancy of the water, thereby achieving the effect of automatically cleaning the seepage holes.

[0035] Specifically, the permeation plate 22 and the control plate 23 are provided with water outlet holes. In the initial state, the water outlet holes on the permeation plate 22 and the water outlet holes on the control plate 23 are misaligned, and the control plate 23 rotates relative to the permeation plate 22. The connecting rod 24 is located at the center of the rotating plate 313.

[0036] Specifically, the rotating plate 313 has a notch, and the notch is set at an angle.

[0037] Specifically, the control mechanism 3 includes a control box 31, with a water outlet plate 32 on one side of the control box 31 and a mating plate 34 on the inner side of the control box 31. The water outlet plate 32 and the mating plate 34 are arranged opposite to each other. A partition plate 38 is arranged in the middle of the control box 31. A flow channel is formed in the partition plate 38, and a water outlet barrier plate 311 is slidably arranged at the corresponding position of the flow channel. A limiting spring block 35 is arranged on the partition plate 38. An auxiliary plate 33 and a floating plate 39 are respectively arranged on both sides of the partition plate 38. The auxiliary plate 33 is connected to the mating plate 34. A reset spring 37 is provided between the auxiliary plate 33 and the control box 31. An abutment block is provided on the upper surface of the auxiliary plate 33. A connecting plate 310 is provided on the upper surface of the floating plate 39. A limiting block 36 is provided on one side of the connecting plate 310. An abutment spring block 312 is provided on the partition plate 38. The abutment spring block 312 is located above the water outlet barrier plate 311. A flow hole is provided on the side wall of the control box 31, and the flow hole is located above the floating plate 39 in the initial state.

[0038] Specifically, the water outlet plate 32 and the mating plate 34 are provided with two sets of seepage holes at their upper and lower ends. In the initial state, the seepage holes at the upper end of the water outlet plate 32 overlap with the seepage holes at the upper end of the mating plate 34.

[0039] During operation, in the initial power-accumulation phase, water will first enter the area above the auxiliary plate 33, thereby compressing the return spring 37 and achieving the power-accumulation effect. Only when the auxiliary plate 33 is lowered to a certain extent due to gravity will water enter through the area below the auxiliary plate 33 and then flow into the floating plate 39, causing the floating plate 39 to float.

[0040] Specifically, the bottom of the partition plate 38 does not contact the inner surface of the control box 31.

[0041] During operation, the bottom of the partition plate 38 does not contact the control plate, allowing water to circulate normally, thus achieving the effect of drip irrigation.

[0042] Specifically, the contact surfaces of the abutting block and the abutting auxiliary block are inclined surfaces.

[0043] When in use, since the auxiliary contact block is located on the side of the contact block, the contact block will be displaced when the auxiliary contact block comes into contact with the contact block.

[0044] Specifically, the contact surface between the abutment block and the rotating plate 313 is an inclined surface, and the notches on the abutment block and the rotating plate 313 are positioned correspondingly.

[0045] During operation, the displaced contact block abuts against the rotating plate 313, causing the rotating plate 313 to rotate. The rotation of the rotating plate 313 drives the control plate 23 to rotate via the connecting rod 24, thereby achieving the effect of enlarging the water outlet.

[0046] Working principle: In the initial stage of drip irrigation, since there is no water in the control box 31, the floating plate 39 is located at the bottom of the control box 31, while the auxiliary plate 33 is located at the top under the action of the return spring 37. At this time, the seepage holes on the upper part of the outlet plate 32 correspond to the seepage holes on the upper part of the mating plate 34, while the seepage holes on the lower part of the outlet plate 32 are misaligned with the seepage holes on the mating plate 34. At this time, the water in the drip irrigation pipe 11 will first enter the auxiliary plate 33. As the water on the auxiliary plate 33 increases, the auxiliary plate 33 will compress the return spring 37 under the action of gravity, causing it to move downward. During the downward movement of the auxiliary plate 33, it will push the limiting spring block 35, causing it to move to the limiting spring block 36. Below 5, the seepage holes on the upper part of the water outlet plate 32 are misaligned with the seepage holes on the upper part of the mating plate 34, and the seepage holes on the lower part of the water outlet plate 32 correspond to the seepage holes on the mating plate 34. Water no longer enters the upper part of the auxiliary plate 33. Water then enters from the lower part of the auxiliary plate 33 and flows to the lower part of the floating plate 39. The floating plate 39 moves upward under the buoyancy of the water until it reaches the flow hole. Simultaneously, as the floating plate 39 moves upward, it drives the connecting plate 310 above it to move upward as well. When the connecting plate 310 reaches a certain position, it will contact the water outlet baffle plate 311, causing it to move upward. The flow channel blocked by the water-blocking baffle plate opens, and water enters the upper part of the floating plate 39. The water then flows out through the flow hole. When the floating plate 39 moves into position, the limiting block 36 is located outside the limiting spring block 35, preventing it from moving. Although there is no water above the auxiliary plate 33 at this time, the limiting block 36 restricts the movement of the limiting spring block 35, causing the auxiliary plate 33 to also be unable to move under the action of the return spring 37, thus achieving a jamming effect. However, with continuous use, the seepage hole will become clogged, causing a difference in the inflow and outflow of water. The water below the floating plate 39 will increase, causing the floating plate 39 to move upwards a second time. When the limiting block 36 no longer restricts the spring block 35, the auxiliary plate 33 will instantly reset under the action of the return spring 37. The reset of the auxiliary plate 33 causes the contact auxiliary block to move upward, and the upward movement of the contact auxiliary block to contact the contact block, causing it to shift. The shifted contact block then contacts the rotating plate 313. Due to the use of an inclined plane, the rotating plate 313 will deflect at a certain angle. The rotating plate 313 drives the control plate 23 to rotate through the connecting rod 24. The diameter of the water outlet holes of the seepage plate 22 and the control plate 23 increases, resulting in a relative pulling effect between the seepage plate 22 and the control plate 23. At this time, the impurities that are filled in the overlap of the seepage plate 22 and the control plate 23 will become loose and the water outlet diameter will increase, making it easier to flush them out, thereby achieving the self-cleaning effect. Then, a new round of energy storage begins, which is convenient for the next round of self-cleaning.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
