Description

Technical Field

[0001] The present invention belongs to the technical field of farmland irrigation, and in particular relates to an intelligent farmland water conservancy irrigation pump station. Background Art

[0002] In the process of farmland irrigation, it is usually necessary to use a pump station to draw water from the water source to the farmland for irrigation. Existing farmland irrigation pump stations usually include a pump station body, a water pump, and a water pipeline. Its working principle is to use a water pump to draw water from the water source to the pump station body, and then transport the water to the farmland through the water pipeline to achieve irrigation and fertilization operations on the farmland;

[0003] In order to save water resources and carry out precise irrigation, most of the existing methods are to lay drip irrigation pipes and spray pipes in the farmland to achieve drip irrigation and spray watering operations on the plants planted in the farmland.

[0004] However, when drip irrigation pipes are used for drip irrigation and fertilization of farmland plants, most of them are directly straightened and laid at the roots of plants, and then drip irrigation or fertilization is carried out. However, if the drip irrigation pipes are straightened and laid for drip irrigation in farmland with serious soil loss or certain slopes, it will inevitably lead to large-scale direct loss of water or fertilizer dripped to the roots of plants, which will not only affect the efficiency of drip irrigation for planted plants, but also easily cause waste of water resources and soil. Summary of the invention

[0010] Furthermore, a fertilizer adding mechanism is provided on one side of the elastic thin plate that forms a circular ring, and the fertilizer adding mechanism includes a mixing cylinder, a fertilizer cylinder, a dilution conduit and a first diversion hose. The mixing cylinder is fixedly supported between the elastic thin plate and the diversion hose by a bracket, and the top of the mixing cylinder is connected to the fertilizer cylinder, and the fertilizer cylinder is provided with a fertilizer adding port.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention lays the drip irrigation hose in a circular ring shape around the roots of plants, and lays and installs it through an annular water retaining mechanism. The drip irrigation hose sprays water to the roots of plants in an annular drip irrigation manner, and the sprayed water source is blocked and gathered at the roots of plants by the annular water retaining mechanism, so that the drip irrigation water source will not be lost in large quantities from the roots of plants due to the characteristics of the soil and the slope of the farmland. Therefore, while reducing the waste of water sources, the roots of plants can be fully watered. At the same time, fertilizer solution can be sprayed to the roots of plants in an annular drip irrigation manner as needed, so that the fertilizer solution of drip irrigation can be fully immersed in the roots of plants for fertilization, and the loss and waste of fertilizer solution will not be caused.

[0016] 2. The present invention installs the drip irrigation hose in a circular ring shape into an elastic thin plate in a circular ring shape whose size can be adjusted. When the nut on the adjusting screw is slowly loosened, the compressed spring member will push the symmetrical connecting blocks to separate from each other, thereby increasing the diameter of the circular ring formed by the elastic thin plate. Since the drip irrigation hose is slidably inserted into the drip irrigation support block, the diameter of the elastic thin plate in the circular ring increases. At this time, the free end of the drip irrigation hose will also slide freely, so that the diameter of the circular ring formed by it will increase synchronously, so that the annular water retaining mechanism can adjust the diameter size according to the size of the plant's roots, so that the plants planted in the farmland can be fully drip-irrigated and water-retaining operations can be performed. Since the drip irrigation hose is located in the middle of the elastic thin plate, the water source or fertilizer blocked by the elastic thin plate will not cause blockage to the drip irrigation hole of the drip irrigation hose.

[0017] 3. The present invention arranges a fertilizer conveying assembly in the fertilizer barrel and the mixing barrel. When the impeller blade is aligned with the pipe mouth of the dilution duct, the injected water source will push the impeller blade to rotate, so that the driving rod drives the spiral blade to rotate in the mixing barrel and the fertilizer barrel, and then the powder fertilizer in the fertilizer barrel can be downwardly conveyed into the mixing barrel, and the powder fertilizer falling through the fertilization hole will be diffused into the mixing barrel again through the rotating impeller blade and fully contact with the injected water source, thereby improving the dilution and mixing effect of the powder fertilizer in the mixing barrel, when the boss on the upper surface of the impeller disk is sealed and inserted into the fertilization hole, the fertilization hole is blocked, so that the mixing barrel and the fertilizer barrel are sealed and separated, to prevent that when only water source is injected into the mixing barrel, part of the powder or liquid fertilizer in the fertilizer barrel falls into the mixing barrel through the gap between the spiral blade and the diameter of the fertilization hole, which is easy to cause unnecessary waste.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 6 As shown, the present invention is a smart farmland water conservancy irrigation pump station, including a pump station house 1, which is connected to the control system of the smart farmland, the water inlet of the pump station house 1 is connected to the nearby water area, and the water outlet is connected to the water pump on the water storage tank 2 through a conduit, the bottom end of the water storage tank 2 is connected to the irrigation main pipe 3 through a conduit, the side of the irrigation main pipe 3 is detachably connected with a plurality of shunt pipes 4, and the side of each of the shunt pipes 4 is detachably connected with a plurality of drip irrigation hoses 5 through a plurality of connecting conduits 41, each of the drip irrigation hoses 5 is laid in an annular manner around the root of the plant through an annular water retaining mechanism 6, and the annular water retaining mechanism 6 is used to block the drip irrigation water or fertilizer water dripped by the drip irrigation hose 5 at the root of the plant;

[0038] Specifically, the present invention lays the drip irrigation hose 5 in a circular ring shape around the roots of the plants, and is laid and installed through a circular water retaining mechanism 6. Therefore, when the plants planted in the farmland need to be watered or fertilized regularly, the pump station 1 is controlled by the control system of the smart farmland to transport the water source to the water storage tank 2, and then transport it to the irrigation main pipe 3 through the pump body, and then multiple diversion pipes 4 will divert the water source to the detachable and circular drip irrigation hose 5. Therefore, the drip irrigation hose 5 will spray the water source in a circular drip irrigation manner. The water source of the drip irrigation system will be blocked by the annular water retaining mechanism 6 and gathered at the roots of the plants, so that the water source of the drip irrigation will not be lost from the roots of the plants in large quantities due to the characteristics of the soil and the slope of the farmland. Therefore, under the premise of reducing the waste of water source, the roots of the plants can be fully watered. At the same time, the fertilizer solution can be sprayed to the roots of the plants through annular drip irrigation as needed, so that the fertilizer solution of the drip irrigation can be fully immersed in the roots of the plants for fertilization, and the loss and waste of the fertilizer solution will not be caused.

[0039] In the scheme designed by the present invention, the annular water retaining mechanism 6 includes an elastic thin plate 61, a connecting block 62, a supporting block 63, a ground-inserting rod 64, a drip irrigation support block 65, an adjusting screw 66 and a spring member 67. The elastic thin plate 61 is laid in a circular ring shape around the roots of the plants, and the elastic thin plate 61 in a circular ring shape is located on the outer side of the drip irrigation hose 5 in a circular ring shape. The connecting block 62 is symmetrically fixed at the notch of the elastic thin plate 61 in a circular ring. A plurality of supporting blocks 63 are fixed to the outer ring surface of the elastic thin plate 61, and a ground-inserting rod 64 is slidably inserted in each supporting block 63. The bottoms of the plurality of ground-inserting rods 64 are inserted into the soil around the roots of the plants. In the embodiment, the inner circumferential array of the elastic thin plate 61 has a plurality of drip irrigation support blocks 65, and the plurality of drip irrigation support blocks 65 are slidably sleeved on the drip irrigation hose 5, and the plurality of drip irrigation support blocks 65 are used to slide and support the drip irrigation hose 5 in a circular ring, and the symmetrical connecting blocks 62 are connected by the cooperation of the adjusting screw 66 and the nut, and the adjusting screw 66 is sleeved with a spring member 67, and the two ends of the spring member 67 are respectively in contact with the symmetrical connecting blocks 62, and the elastic thin plate 61 is provided with a guide sliding hole 611 for the drip irrigation hose 5 to slide through, and the drip irrigation hose 5 in a circular ring shape is located in the middle of the elastic thin plate 61 in a circular ring shape;

[0040] Specifically, when it is necessary to lay the drip irrigation hose 5 with one end sealed at the root of the plant, the sealed end of the drip irrigation hose 5 is first slid through the guide slide hole 611 and the plurality of drip irrigation support blocks 65 in sequence, and installed on the inner side of the elastic thin plate 61, and then the adjusting screw 66 is inserted into the symmetrical connecting blocks 62, and at this time the spring member 67 abuts between the symmetrical connecting blocks 62, and then the adjusting screw 66 is locked by the nut, so that the elastic thin plate 61 is elastically bent into a ring shape and laid around the root of the plant, and then the elastic thin plate is adjusted as needed. The bottom end of 61 is inserted into or contacts the soil surface, and then a plurality of ground-inserting rods 64 are sequentially inserted into a plurality of support blocks 63, so as to facilitate laying the drip irrigation hose 5 in a circular ring shape at the root of the plant, and then the other end of the drip irrigation hose 5 is connected to the corresponding connecting valve on the shunt pipe 4, so as to realize the circular drip irrigation or fertilization operation for the plant roots, and the elastic thin plate 61 that forms a circular ring is in contact with or inserted into the soil, so that the water source or fertilizer of the circular drip irrigation to the plant root can be blocked, which can not only prevent the water source or fertilizer of the drip irrigation from flowing in large quantities, but also prevent the water source or fertilizer of the drip irrigation from flowing in large quantities. At the same time, the drip irrigation water or fertilizer can be fully immersed into the roots of the plants, thereby further improving the efficiency of the water conservancy irrigation pump station in irrigating the plants planted in the farmland; and as the plants continue to grow, their roots will continue to grow. Therefore, the operator can regularly remove the ground-inserting rod 64 from the soil as needed, and then slowly loosen the nut on the adjusting screw 66. The compressed spring member 67 will push the symmetrical connecting blocks 62 to separate from each other, thereby increasing the diameter of the circular ring formed by the elastic thin plate 61, and because the drip irrigation hose 5 It is slidably inserted into the drip irrigation support block 65, so that the diameter of the elastic thin plate 61 forming a circular ring increases. At this time, the free end of the drip irrigation hose 5 will also slide freely, so that the diameter of the circular ring formed by it increases synchronously, so that the annular water retaining mechanism 6 can adjust the diameter size according to the size of the root of the plant, so that the plants planted in the farmland can be fully drip-irrigated and water-retaining operations can be performed. Since the drip irrigation hose 5 is located in the middle of the elastic thin plate 61, the water source or fertilizer blocked by the elastic thin plate 61 will not cause blockage to the drip irrigation hole of the drip irrigation hose 5.

[0041] In the scheme designed by the present invention, the annular water retaining mechanism 6 also includes an arc plate 68 and an arc guide bar 69. The arc plate 68 of elastic material is sealed and fitted at the notch of the elastic thin plate 61 that forms a circular ring. One end of the arc plate 68 is fixed under one of the connecting blocks 62, and the other end thereof is slidably fitted under another connecting block 62. The back of the other connecting block 62 is fixed with an arc guide bar 69, and the sliding arc plate 68 is inserted in the arc guide bar 69.

[0042] Specifically, when the diameter of the elastic thin plate 61 formed in a circular shape is adjusted, the slidably fitted arc plate 68 will synchronously slide in the arc guide bar 69, so that the arc plate 68 can always seal the gap of the circular elastic thin plate 61, preventing the water or fertilizer drip-irrigated to the roots of the plants from being lost from the gap, thereby affecting the effect of drip irrigation or fertilization on the plants planted in the farmland.

[0043] In the scheme designed by the present invention, a long slot hole 631 is provided on the support block 63 whose outer ring surfaces are aligned with each other, and the two aligned support blocks 63 are slidably inserted into the guide slot 71 provided on the guide support block 7. The guide support block 7 is connected to the two symmetrical support blocks 63 by bolts, and a ground insertion rod 64 is slidably inserted in the middle of the guide support block 7.

[0044] Specifically, two adjacent support blocks 63 are fixed by the cooperation of the guide support block 7 and the bolts and the same ground-inserted rod 64, so that when the elastic thin plate 61 is adjusted, it is only necessary to loosen the corresponding two bolts on the guide support block 7. Then, when the elastic thin plate 61 in a circular shape expands, it will push the support block 63 to slide freely in the guide slot 71, and then the corresponding bolts will be tightened. There is no need to pull the same ground-inserted rod 64 between the two adjacent support blocks 63 out of the soil, so that the size of the elastic thin plate 61 in a circular shape can be quickly adjusted.

[0045] In the scheme designed by the present invention, a fertilizer adding mechanism 8 is provided on one side of the elastic thin plate 61 that forms a circular ring, and the fertilizer adding mechanism 8 includes a mixing cylinder 81, a fertilizer cylinder 82, a dilution conduit 83 and a first diversion hose 84. The mixing cylinder 81 is fixedly supported between the elastic thin plate 61 and the diversion pipe 4 by a bracket, and the top of the mixing cylinder 81 is connected with the fertilizer cylinder 82, and the fertilizer cylinder 82 is provided with a fertilizer adding port. A side wall of the mixing cylinder 81 is connected to the electromagnetic connecting valve vertically installed on the diversion pipe 4 through the dilution conduit 83, and other parts of the mixing cylinder 81 are detachably connected to the drip irrigation hose 5 through the first diversion hose 84;

[0046] Specifically, when it is necessary to fertilize the roots of a single or local plant through the drip irrigation hose 5, since the fertilizer tank storing a large amount of fertilizer is placed indoors, the fertilizer in the fertilizer tank can be controlled by the control system of the smart farmland to pass through the pump body and the conduit connected to the fertilizer adding port to add the fertilizer to be applied to the fertilizer barrel 82, and the fertilizer added in the fertilizer barrel 82 will fall into the mixing barrel 81 below, and then the electromagnetic connecting valve connected to the dilution conduit 83 is opened, so that the water source will enter the mixing barrel 81 to dissolve and mix the fertilizer, and then be diverted to the corresponding drip irrigation hose 5 through the first diversion hose 84, and then the fertilizer solution entering the drip irrigation hose 5 will be synchronously drip-irrigated to the roots of the plants with the water source. At this time, the elastic thin plate 61 formed in a circular ring will block the drip irrigation fertilizer solution, so that the drip irrigation fertilizer solution will fully fertilize the roots of the plants, and there will be no large-scale loss of the fertilizer solution applied by drip irrigation.

[0047] In the solution designed by the present invention, the fertilizer adding mechanism 8 also includes a spray pipe 85 and a second diversion hose 86. The two symmetrical spray pipes 85 are vertically installed on two symmetrical ground-inserted rods 64, and the height of the spray head of the spray pipe 85 is higher than the height of the planted plants. The spray pipe 85 is connected to the mixing cylinder 81 through a detachable second conduit.

[0048] Specifically, the spray pipe 85 is combined with the ground-inserted rod 64, and the nozzle of the spray pipe 85 is higher than the height of the plant. When fertilization is not needed, the water source entering the mixing cylinder 81 through the dilution conduit 83 will be injected into the spray pipe 85 through the second diversion pipe 4, and the solenoid valve on the second diversion hose 86 is in a closed state. Then, the nozzle of the spray pipe 85 will spray the water source onto the leaves of the plant, so as to realize the sprinkler irrigation around the plant. When fertilization is needed on the leaves of the plant, the second diversion hose 86 can be closed at this time. The solenoid valve on the flow hose 86 adds the foliar fertilizer into the fertilizer barrel 82, and then drops into the mixing barrel 81 to be diluted by the water source. The diluted fertilizer solution will enter the spray pipe 85 through the second diverter hose 86 to spray the fertilizer on the leaves of the plants. If only the roots of the plants need to be fertilized, the solenoid valve on the second diverter pipe 4 needs to be closed at this time, so that the fertilizer acting on the roots will only enter the drip irrigation hose 5 through the first diverter hose 84, and drip irrigation and fertilization operations will be performed on the roots of the plants.

[0049] In the solution designed by the present invention, a fertilizer conveying assembly 9 is arranged between the mixing cylinder 81 and the fertilizer cylinder 82, and the fertilizer conveying assembly 9 includes a driving rod 91, an impeller blade 92, a spiral blade 93, an electric push rod 94 and a support plate 95. A fertilizer adding hole 96 is opened between the mixing cylinder 81 and the fertilizer cylinder 82, and the driving rod 91 is vertically inserted into the mixing cylinder 81 and the fertilizer cylinder 82, and the rod body of the driving rod 91 is slidably inserted into the fertilizer adding hole 96, and the top end of the driving rod 91 slides upward and extends out of the fertilizer cylinder 82, and the bottom of the driving rod 91 is An impeller blade 92 is fixed at the end, and the impeller blade 92 is located in the mixing barrel 81. A spiral blade 93 is fixedly sleeved on the driving rod 91, and the spiral blade 93 slides through the fertilizer adding hole 96. The top end of the extended driving rod 91 is rotatably connected to a support plate 95, and the support plate 95 is connected to the piston rod of a vertically fixed electric push rod 94. The pipe opening height of the dilution duct 83 connected to the mixing barrel 81 is greater than the pipe opening heights of the first diversion hose 84 and the second diversion hose 86, and the impeller blade 92 is slidably aligned with the pipe opening of the dilution duct 83;

[0050] Specifically, when it is necessary to transport the fertilizer added to the fertilizer barrel 82 to the mixing barrel 81, the piston rod of the electric push rod 94 is controlled to be retracted, so that it drives the driving rod 91 to slide down synchronously in the mixing barrel 81 and the fertilizer barrel 82 through the support plate 95, and the impeller blade 92 at the bottom of the driving rod 91 will be flush with the center of the nozzle of the dilution duct 83, and the spiral blade 93 will continue to be located in the mixing barrel 81 and the fertilizer barrel 82. Therefore, when the dilution duct 83 injects a water source of a certain pressure into the mixing barrel 81, the water source will push the impeller blade 92 to rotate, so that the driving rod 91 drives the spiral blade 93 to rotate in the mixing barrel 81 and the fertilizer barrel 82, and then the powder fertilizer in the fertilizer barrel 82 can be transported downward into the mixing barrel 81, and the powder fertilizer falling through the fertilizer adding hole 96 will be diffused into the mixing barrel again through the rotating impeller blade 92 81 is in full contact with the injected water source, thereby being able to improve the dilution and mixing effect of the powder fertilizer in the mixing barrel 81. When fertilization operation is not needed, the piston rod of the electric push rod 94 is controlled to extend, so that it drives the driving rod 91 and the impeller blade 92 to move upward and detach from the pipe mouth of the dilution duct 83. Therefore, when the dilution duct 83 continues to transport the water source into the mixing barrel 81, the fertilizer in the fertilizer barrel 82 will not fall into the mixing barrel 81 and cause fertilization operation by mistake. Since the pipe mouth height of the dilution duct 83 is greater than the pipe mouth height of the two diversion hoses, the phenomenon that the water source injected into the mixing barrel 81 is higher than the pipe mouth of the dilution duct 83 will not occur, so that the injected water source can continuously drive the impeller blade 92 to rotate, and the powder fertilizer added in the fertilizer barrel 82 is transported to the mixing barrel 81 for sufficient dilution and mixing operation.

[0051] In the solution designed by the present invention, the diameter of the impeller disc 921 of the impeller blade 92 is larger than the diameter of the fertilizer hole 96, and the upper surface of the impeller disc 921 is convex, and the length of the spiral blade 93 is smaller than the height of the fertilizer barrel 82;

[0052] Specifically, when the driving rod 91 drives the impeller blade 92 to slide upward and detach from the pipe mouth of the dilution duct 83, the boss on the upper surface of the impeller disk 921 will be sealed and inserted into the fertilizer hole 96 to achieve the blocking of the fertilizer hole 96, so that the mixing barrel 81 and the fertilizer barrel 82 are sealed and separated, and it is prevented that when only the water source is injected into the mixing barrel 81, part of the powder or liquid fertilizer in the fertilizer barrel 82 falls into the mixing barrel 81 through the gap between the spiral blade 93 and the diameter of the fertilizer hole 96, which is easy to cause unnecessary waste; at the same time, the height of the spiral blade 93 is less than the height of the fertilizer barrel 82, so that the spiral blade 93 will not interfere when it rises in the fertilizer barrel 82, and will not affect the blocking of the fertilizer hole 96 by the boss of the impeller disk 921. The rotating conveying of the spiral blade 93 can convey the powder fertilizer added in the fertilizer barrel 82, and prevent the powder fertilizer from being stored in the fertilizer barrel 82 for a long time and agglomerating, and cannot freely fall to the mixing barrel 81 to mix and dilute with the water source.
