Description

Technical Field

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

[0002] Drip irrigation is a method of irrigation in which water with a certain pressure is filtered and dripped slowly and evenly into the soil near the roots of plants through a pipe network and an outlet pipe () or a dripper in the form of water drops. The effective utilization rate of water is high. Under drip irrigation conditions, the irrigation water wets part of the soil surface, which can effectively reduce the ineffective evaporation of soil moisture. At the same time, since drip irrigation only wets the soil near the roots of crops, the moisture content of the soil in other areas is low, thus preventing the growth of weeds. The drip irrigation system does not produce surface runoff, and it is easy to master the precise watering depth, which is very water-saving.

[0003] When drip irrigation is used for watering, uneven flow from the drip irrigation head often occurs. The purpose of the drip irrigation system is to provide water to plants evenly. Uneven flow will cause some plants to get too much water, while other plants may lack water, affecting the consistency of crop growth. Uneven flow will lead to uneven distribution of soil moisture, which may cause soil salt accumulation or soil erosion. Excessive water may cause root diseases, while insufficient water may make plants more susceptible to drought stress and pests and diseases.) The phenomenon of uneven drip irrigation occurs because the flow of the drip irrigation head is proportional to the liquid circulation pressure in the pipe. The reasons for the change in pressure inside the pipe are:

[0004] During the drip irrigation process, although a pre-filtration mechanism is set up, there are still minerals in the water. Over time, crystallization will occur, causing the drip irrigation head to become blocked, resulting in uneven final drip irrigation volume. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. The embodiment of the present invention provides an agricultural water-saving drip irrigation device to solve the technical problem that the existing drip irrigation device is affected by the pipeline, resulting in pressure difference and the drip irrigation head is blocked, resulting in different drip irrigation amounts in different areas.

[0006] The embodiment of the present invention adopts the following technical scheme: a water-saving drip irrigation device for agricultural planting, including a drip irrigation main pipe and a drip water branch pipe, and also including a drip irrigation mechanism for discharging water, which cooperates with a control mechanism to prevent the drip irrigation mechanism from being blocked. The drip irrigation mechanism includes a drip irrigation head, a water seepage plate is arranged at the end of the drip irrigation head, a regulating plate is arranged on the inner side of the water seepage plate, a torsion spring is arranged between the regulating plate and the water seepage plate, a connecting rod is arranged on the inner side of the regulating plate, a rotating plate is arranged at the end of the connecting rod, and a connecting bolt for connecting with the drip irrigation branch pipe is arranged at the end of the drip irrigation head.

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

[0008] Furthermore, a notch is provided on the rotating plate, and the notch is arranged as an inclined surface.

[0009] Further, the control mechanism includes a control box, a water outlet plate is provided on one side of the control box, a matching plate is provided on the inner side of the control box, the water outlet plate and the matching plate are arranged opposite to each other, a partition plate is provided in the middle position of the control box, a flow groove begins in the partition plate, and a water outlet baffle plate is slidably provided at the corresponding position of the flow groove, a limiting spring block is provided on the partition plate, an auxiliary plate and a floating plate are respectively provided on both sides of the partition plate, the auxiliary plate is connected to the matching plate, a return spring is provided between the auxiliary plate and the control box, an auxiliary block is provided on the upper surface of the auxiliary plate, a connecting plate is provided on the upper surface of the floating plate, a limiting block is provided on one side of the connecting plate, a contact spring block is provided on the partition plate, the contact spring block is located above the water outlet baffle plate, a flow hole is provided on the side wall of the control box, and the flow hole is located above the floating plate in the initial state.

[0010] Furthermore, two groups of water seepage holes are provided at the upper and lower ends of the water outlet plate and the matching plate. In an initial state, the water seepage holes at the upper end of the water outlet plate overlap with the water seepage holes at the upper end of the matching 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 abutment block and the auxiliary abutment block are inclined surfaces.

[0013] Furthermore, the contact surface between the abutment block and the rotating plate is an inclined surface, and the positions of the notches formed on the abutment block and the rotating plate correspond to each other.

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

[0015] In view of the fact that the existing drip irrigation head is clogged due to its slow flow rate, long flow path and small hole diameter, the drip irrigation mechanism and the control mechanism in the present invention cooperate to make it possible to use the gravity of water to store power before drip irrigation. Then, the drip irrigation head of the drip irrigation mechanism is improved so that the drip irrigation hole of the drip irrigation head can achieve the drip irrigation effect through two offset orifice plates that can move relatively.

[0016] However, due to the influence of different water qualities, the clogging time of the drip irrigation head is not a fixed value. Therefore, it is necessary to judge whether the drip irrigation head is blocked. The judgment principle in the present invention is to judge whether there is a difference between the inlet and outlet water. During continuous use, the water inlet and outlet should be in a relatively balanced state. When the drip irrigation head is blocked, the water outlet will be less than the water inlet. When the blockage occurs, the control mechanism with accumulated force will drive the staggered diameters of the water outlet holes of the seepage plate and the regulating plate in the drip irrigation mechanism to increase, so that the seepage plate and the regulating plate have a relative pulling effect. At this time, the impurities filled in the overlapping of the seepage plate and the regulating plate will become loose and the water outlet diameter will become larger, making it easier to flush them out.

[0017] To sum up, the drip irrigation device does not require an additional power source during use. The energy storage utilizes the water's own gravity, and whether it is blocked is determined based on subsequent triggering, utilizing the difference in water inflow and outflow, as well as the buoyancy of water, thereby achieving the effect of automatically cleaning the seepage holes.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Combine the following Figures 1 to 7As shown, an embodiment of the present invention provides a water-saving drip irrigation device for agricultural planting, including a drip irrigation main pipe 1 and a drip branch pipe, and also includes a drip irrigation mechanism 2 for discharging water, and a control mechanism 3 that cooperates to prevent the drip irrigation mechanism 2 from being blocked. The drip irrigation mechanism 2 includes a drip irrigation head 21, and a water seepage plate 22 is arranged at the end of the drip irrigation head 21, and a regulating plate 23 is arranged inside the water seepage plate 22. A torsion spring is arranged between the regulating plate 23 and the water seepage plate 22, and a connecting rod 24 is arranged inside the regulating plate 23, and a rotating plate 313 is arranged at the end of the connecting rod 24. A connecting bolt for connecting with the drip irrigation branch pipe 11 is arranged at the end of the drip irrigation head 21.

[0034] When working, the drip irrigation device does not require an additional power source during use. The energy storage utilizes the water's own gravity, and whether it is blocked is determined based on subsequent triggering, utilizing the difference in water inflow and outflow, as well as the buoyancy of water, thereby achieving the effect of automatically cleaning the seepage holes.

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

[0036] Specifically, a notch is provided on the rotating plate 313, and the notch is arranged in an inclined surface.

[0037] Specifically, the control mechanism 3 includes a control box 31, a water outlet plate 32 is arranged on one side of the control box 31, a matching plate 34 is arranged on the inner side of the control box 31, the water outlet plate 32 and the matching plate 34 are arranged opposite to each other, a partition plate 38 is arranged in the middle of the control box 31, a flow groove is provided in the partition plate 38, and a water outlet baffle plate 311 is slidably arranged at a position corresponding to the flow groove, a limiting spring block 35 is arranged on the partition plate 38, and auxiliary plates 33 and floating plates 39 are respectively arranged on both sides of the partition plate 38, and the auxiliary plates 33 and floating plates 39 are arranged on both sides of the partition plate 38. The auxiliary plate 33 is connected to the matching plate 34, a return spring 37 is arranged between the auxiliary plate 33 and the control box 31, an auxiliary resistance block is arranged on the upper surface of the auxiliary plate 33, a connecting plate 310 is arranged on the upper surface of the floating plate 39, a limiting block 36 is arranged on one side of the connecting plate 310, a resistance spring block 312 is arranged on the partition plate 38, and the resistance spring block 312 is located above the water outlet baffle plate 311, and a flow hole is arranged 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, two groups of water seepage holes are opened at the upper and lower ends of the water outlet plate 32 and the matching plate 34 . In an initial state, the water seepage holes at the upper end of the water outlet plate 32 overlap with the water seepage holes at the upper end of the matching plate 34 .

[0039] During operation, in the initial force accumulation stage, water will first enter the top of the auxiliary plate 33, thereby compressing the reset spring 37 and achieving the effect of force accumulation. Only when the auxiliary plate 33 moves down to a certain extent under the influence of gravity, water will enter through the bottom of 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, since the bottom of the partition plate 38 is not in contact with the control plate, water can flow normally, thereby achieving a drip irrigation effect.

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

[0043] When in use, since the auxiliary resistance block is located at the side of the resistance block, when the auxiliary resistance block resists the resistance block, the resistance block will be displaced.

[0044] Specifically, the contact surface between the abutment block and the rotating plate 313 is an inclined surface, and the positions of the notches on the abutment block and the rotating plate 313 correspond to each other.

[0045] During operation, the displaced abutment block abuts against the rotating plate 313, so that the rotating plate 313 rotates. The rotating plate 313 rotates, and the regulating plate 23 is driven 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, and the auxiliary plate 33 is located at the upper end under the action of the reset spring 37. At this time, the upper seepage hole on the water outlet plate 32 corresponds to the position of the upper seepage hole on the matching plate 34, and the lower seepage hole on the water outlet plate 32 is misaligned with the seepage hole on the matching plate 34. At this time, the water in the drip irrigation branch pipe 11 will first enter the auxiliary plate 33. As the water on the auxiliary plate 33 continues to increase, the auxiliary plate 33 will compress the reset spring 37 under the action of gravity to make it move downward continuously. In the process of the auxiliary plate 33 moving downward, it will push the limiting spring block 35 to move to the limiting spring block 3 5, then at this time, the upper seepage hole on the water outlet plate 32 is misaligned with the upper seepage hole on the matching plate 34, the lower seepage hole on the water outlet plate 32 corresponds to the position of the seepage hole on the matching plate 34, and water no longer enters the upper part of the auxiliary plate 33. At this time, water enters from the lower part of the auxiliary plate 33, and the water will enter the lower part of the floating plate 39. The floating plate 39 continues to move upward under the buoyancy of the water until the floating plate 39 moves to the flow hole. At the same time, in the process of the floating plate 39 moving upward, the connecting plate 310 set above will be driven to move upward synchronously. When the connecting plate 310 moves up to a certain position, it will contact the water outlet blocking plate 311, causing it to move upward, and the flow slot blocked by the water blocking plate is opened, and water enters the upper part of the floating plate 39. The water below the floating plate 39 begins to increase, causing the floating plate 39 to move up a second time. When the limiting block 36 no longer limits the spring block 35, the auxiliary plate 33 is instantly reset under the action of the reset spring 37, and the auxiliary plate 33 is stuck. The auxiliary plate 33 is reset to drive the auxiliary block to move upward, and the auxiliary block moves upward to resist the resistance block, causing it to be displaced. The resistance block is displaced to resist the rotating plate 313. Due to the use of the inclined surface, the rotating plate 313 will deflect at a certain angle at this time. The rotating plate 313 drives the regulating plate 23 to rotate through the connecting rod 24. The staggered diameters of the water outlet holes of the seepage plate 22 and the regulating plate 23 become larger, so that the seepage plate 22 and the regulating plate 23 have a relative pulling effect. At this time, the impurities filled in the overlapping of the seepage plate 22 and the regulating plate 23 will become loose and the water outlet diameter will become larger, making it easier to flush them out, thereby achieving the effect of self-cleaning, and then a new round of power accumulation begins to facilitate 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, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements 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.
