Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation equipment, and in particular to an agricultural irrigation device. Background Art

[0002] The main irrigation methods include sprinkler irrigation, drip irrigation, flood irrigation, and infiltration irrigation. Flood irrigation not only consumes a large amount of water resources but is also difficult to implement in areas with water shortages. Infiltration irrigation can directly supply water to the roots of plants and save water, but the layout cost is high and the irrigation position is relatively fixed, so it can only be used for some plants with similar root lengths. Although drip irrigation saves water, it is prone to blockage and fertilizer accumulation at the drip irrigation point. Therefore, sprinkler irrigation is still the most universal irrigation method. Not only is the irrigation area relatively uniform, it also has the advantages of regulating ambient temperature.

[0003] Most existing sprinkler irrigation equipment is directly laid on the ground, which is convenient for replacing nozzles and laying. However, when loosening the soil, leveling the land, etc., the pipes and nozzles exposed on the ground not only hinder the work, but also the farm tools can easily damage the irrigation equipment during operation, especially in some garden areas, where the laid pipes and nozzles are not conducive to landscaping. For this reason, a buried sprinkler irrigation device has been developed, which can be retracted and hidden when sprinkler irrigation is not needed, which is convenient for gardeners to work, and can automatically rise to sprinkle irrigation when irrigation is needed, but the retractable buried sprinkler head usually needs to be equipped with a corresponding electric-controlled mechanical retractable device, which causes additional costs. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems in the prior art and provide an agricultural irrigation device, which can push out the water pipe and the sprinkler head for the spraying operation from the pre-buried ground, thereby reducing the expenditure of additional costs.

[0005] The present invention provides an agricultural irrigation device, comprising a bearing tube pre-buried underground, a weight block being slidably arranged in the bearing tube, the weight block sliding along the axial direction of the bearing tube, a cavity being arranged in the weight block, the top of the weight block being rotatably connected to a vertically arranged water pipe, a plurality of nozzles being detachably connected to the circumferential side of the top of the water pipe, a baffle being arranged at the bottom of the weight block sliding along the axial direction of the bearing tube, a water inlet pipe being fixedly connected to the bottom of the water pipe via a pair of support rods, the water inlet pipe coinciding with the axis of the water pipe, a sealing plug being slidably embedded in the bottom of the water inlet pipe, the baffle being connected to the sealing plug via a connecting rod, and the plug body being pulled out of the water inlet pipe when the baffle moves downward.

[0006] Preferably, the water pipe is placed on the inner bottom of the weight block and fixedly connected to a support frame, a rotating rod is vertically fixedly connected to the middle of the support frame, a supporting plate is fixedly connected to the bottom end of the rotating rod, and a plurality of blades are fixedly connected to the surrounding side of the supporting plate.

[0007] Preferably, a spiral water inlet channel is opened inside the water inlet pipe.

[0008] Preferably, the blades are all arranged in an arc shape, and the arc directions of several of the blades are consistent.

[0009] Preferably, the supporting tube is fixedly connected to a pair of blocks, the bottom sides of the pair of blocks are fixedly connected to a vertically arranged first fixing rod, the top of the baffle is fixedly connected to a pair of second fixing rods, the top ends of the second fixing rods pass through the weight block, a return spring is sleeved on the second fixing rod, one end of the return spring is fixedly connected to the inner side of the weight block, and the other end is fixedly connected to the baffle, and the first fixing rod and the second fixing rod have the same caliber.

[0010] Preferably, a protective shell is fixedly connected to the top of the water pipe, a limiting plate is fixedly connected to the side of the top of the support pipe, and the upper limit plate is provided with an embedding groove matching the embedding plate.

[0011] Preferably, the load-bearing block has sufficient weight, and the embedded plate is completely embedded in the embedded groove when no sprinkler irrigation is performed.

[0012] Preferably, a plurality of installation pipes are fixedly inserted around the water pipe, and the plurality of installation pipes are composed of two sections, a flexible pipe connected to the water pipe and a rigid pipe of the nozzle.

[0013] Preferably, the nozzle thread is embedded in the end of the rigid tube.

[0014] Preferably, the top of the protective shell is smoothly arranged.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: an agricultural irrigation device of the present invention utilizes the buoyancy of water. Under the action of a water pump, the impact force of water pushes the water pipe and the nozzle for spraying out of the pre-buried ground, thereby reducing the expenditure of additional costs. When spraying is required, the water flow is pressed into the bearing pipe by opening the pump body. At this time, the water flow has a certain impact force, which will push up the load-bearing block slidably set in the bearing pipe. Because the water pipe is set on the top of the load-bearing block, when the load-bearing block moves upward in the bearing pipe, the water pipe will be pushed up from the bearing pipe, and the embedded plate will be separated from the embedded groove. As the load-bearing block is lifted, when it is lifted to the set stopper, the water pipe will be lifted up from the bearing pipe. When the water pipe is in the maximum position, the water pipe is lifted to the maximum height, and the first fixing rod arranged on the baffle will press the second fixing rod arranged on the top of the baffle, so that the baffle slides downward on the weight block. Because the baffle is connected to the plug body by the connecting rod, as the baffle moves downward, the plug body will be pulled out of the water inlet pipe. At this time, part of the water flow will enter the weight block through the water inlet channel. The baffle is not completely separated from the weight block. Most of the impact of the water pressure will still lift and stabilize the weight block. The present invention uses the impact force of water to push the water pipe and the sprinkler head for spraying operation out of the pre-buried ground, thereby reducing the expenditure of additional costs, having strong promotion potential, and being convenient and quick to use.

The drawings in the present invention are not drawn strictly according to the actual scale. The specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structure.

[0027] The present invention provides an agricultural irrigation device, such as Figure 1 to Figure 3As shown, it includes a supporting tube 1 pre-buried in the ground, a load-bearing block 4 is slidably arranged in the supporting tube 1, the load-bearing block 4 slides axially along the supporting tube 1, a cavity is arranged in the load-bearing block 4, the top of the load-bearing block 4 is rotatably connected with a vertically arranged water pipe 2, a plurality of nozzles 3 are detachably connected to the top circumference of the water pipe 2, a baffle 5 is arranged at the bottom of the load-bearing block 4, the baffle 5 is slidably arranged at the bottom of the load-bearing block 4 along the axis 1 of the supporting tube, a water inlet pipe 6 is fixedly connected to the bottom of the water pipe 2 through a pair of support rods 7, the axis of the water inlet pipe 6 coincides with the axis of the water pipe 2, a sealing plug 8 is slidably embedded in the bottom of the water inlet pipe 6, the baffle 5 is connected to the sealing plug 8 through a connecting rod 9, and the sealing plug 8 is pulled out from the water inlet pipe 6 when the baffle 5 moves downward.

[0028] The present invention utilizes the buoyancy of water. Under the action of the water pump, the impact force of the water pushes the water pipe 2 and the nozzle 3 for the spraying operation out of the pre-buried ground, thereby reducing the expenditure of additional costs. When the spraying operation is required, the water flow is pressed into the support pipe 1 by opening the pump body. At this time, the water flow has a certain impact force, which will push up the load block 4 slidably set in the support pipe 1. Because the water pipe 2 is set on the top of the load block 4, when the load block 4 moves upward in the support pipe 1, the water pipe 2 will be pushed up from the support pipe 1, and the embedded plate 20 will be separated from the embedded groove 21. As the load block 4 is lifted, when it is lifted to the position of the set stopper 15, the water pipe 2 is lifted to the maximum height. , and the first fixing rod 16 arranged on the baffle 15 will press the second fixing rod 17 arranged on the top of the baffle 5, so that the baffle 5 slides downward on the weight block 4. Because the baffle 5 is connected to the plug body through the connecting rod 9, as the baffle 5 moves downward, the plug body will be pulled out of the water inlet pipe 6. At this time, part of the water flow will enter the weight block 4 through the water inlet channel 14. The baffle 5 is not completely separated from the weight block 4. Most of the impact of the water pressure will still lift and stabilize the weight block 4. The present invention uses the impact force of water to push the water pipe 2 and the nozzle 3 for spraying operation out of the pre-buried ground, which reduces the expenditure of additional costs, has strong promotion potential, and is convenient and quick to use.

[0029] Preferably, Figure 3 to Figure 8 As shown, the water pipe 2 is placed on the bottom inner side of the weight block 4 and is fixedly connected to a support frame 10, a rotating rod 11 is vertically fixedly connected to the middle of the support frame 10, a support plate 12 is fixedly connected to the bottom end of the rotating rod 11, a plurality of blades 13 are fixedly connected to the peripheral side of the support plate 12, a spiral water inlet channel 14 is opened on the inner side of the water inlet pipe 6, the blades 13 are all arranged in an arc shape, and the arc directions of the plurality of blades 13 are consistent.

[0030] In the present invention, the water pipe 2 is placed in the load block 4 and is equipped with a rotating rod 11 through a support frame 10. The bottom end of the rotating rod 11 is fixedly connected to a support plate 12, and a plurality of blades 13 are fixedly connected to the peripheral side of the support plate 12. Since a spiral water inlet channel 14 is provided in the water inlet pipe 6, the inflowing water has a certain disturbance when entering the load block 4 through the spirally arranged water inlet channel 14, and the blades 13 are arranged in an arc shape and are consistent with the direction of the spiral water inlet channel 14, so that the water flow passing through the water inlet channel 14 can better impact the blades 13. After that, the water flow is transported to the sprinkler head 3 through the water pipe 2 for sprinkler irrigation. The rotating rod 11 will drive the arranged water pipe 2 to rotate, thereby causing the water pipe 2 to rotate, thereby increasing the area that can be covered by sprinkler irrigation.

[0031] Preferably, Figure 1 to Figure 4 As shown, the supporting tube 1 is fixedly connected to a pair of blocks 15, and the bottom sides of the pair of blocks 15 are fixedly connected to a vertically arranged first fixing rod 16. A pair of second fixing rods 17 are fixedly connected to the top of the baffle 5. The top ends of the second fixing rods 17 penetrate the load block 4. A return spring 18 is sleeved on the second fixing rod 17. One end of the return spring 18 is fixedly connected to the inner side of the load block 4, and the other end is fixedly connected to the baffle 5. The first fixing rod 16 and the second fixing rod 17 have the same caliber.

[0032] When lifted to the position of the set block 15, the water pipe 2 is lifted to the maximum height, and the first fixing rod 16 set on the block 15 will press the second fixing rod 17 set on the top of the baffle 5, so that the baffle 5 slides downward on the weight block 4. Because the baffle 5 is connected to the plug body through the connecting rod 9, as the baffle 5 moves downward, the plug body will be pulled out of the water inlet pipe 6. At this time, part of the water flow will enter the weight block 4 through the water inlet channel 14. The baffle 5 is not completely separated from the weight block 4. Most of the impact of the water pressure will still lift and stabilize the weight block 4. A protective shell 19 is fixedly connected to the top of the water pipe 2, and an embedded plate 20 is fixedly connected to the bottom corner of the protective shell 19. The top side of the support tube 1 is fixedly connected to a limiting plate 23. The upper limit plate 23 is provided with an embedded groove 21 matching the embedded plate 20. When the sprinkler irrigation is not performed, the embedded plate 20 is completely embedded in the embedded groove 21.

[0033] After the sprinkler irrigation operation is completed, the water pump is turned off and the water flow in the supporting tube 1 is receded. At this time, the weight block 4 will drive the water pipe 2 to move into the supporting tube 1 under the action of gravity. When the weight block 4 returns to its original position, the embedded plate 20 will be embedded in the embedded groove 21, and the protective shell 19 can protect other components to prevent some debris from falling into the supporting tube 1 and affecting the drive of other components. When the weight block 4 moves downward, the stretched reset spring 18 needs to be reset. As the pressure of the first fixing rod 16 continues to decrease, the reset spring 18 will pull the second fixing rod 17 and the baffle 5, thereby reinserting the plug body into the water inlet pipe 6 through the baffle 5 for sealing.

[0034] Preferably, Figure 7-Figure 8 As shown, a number of installation pipes 22 are fixedly inserted around the water pipe 2. The installation pipes 22 are composed of two sections, a flexible pipe 221 connected to the water pipe 2 and a rigid pipe 222 of the nozzle 3. The nozzle 3 is threadedly embedded in the end of the rigid pipe 222, and the top of the protective shell 19 is smoothly set.

[0035] In the present invention, a plurality of mounting tubes 22 are arranged around the water pipe 2, and the nozzle 3 is threadedly mounted on the mounting tube 22, so that the nozzle 3 can be replaced at any time. Due to the influence of the water source used, scale will accumulate at the nozzle 3 after long-term use, causing clogging of the nozzle 3. The nozzle 3 is threadedly mounted on the mounting tube 22, which is convenient for replacing the nozzle 3, and the threaded installation is more stable and easy to use. In the present invention, the mounting tube 22 is divided into two parts, and the part connected with the water pipe 2 is set as a flexible tube 221. Taking into account different usage conditions, the orientation of the nozzle 3 can be adaptively adjusted as needed. Setting the mounting tube 22 part as a flexible tube 221 can fully meet the above requirements, and setting the part connected with the nozzle 3 as a rigid tube 222 is more convenient for connecting with the nozzle 3.

[0036] The method of using an agricultural irrigation device of the present invention is as follows:

[0037] When the spraying operation is required, the water flow is pressed into the supporting tube 1 by opening the pump body. At this time, the water flow has a certain impact force, which will lift up the weight block 4 slidably set in the supporting tube 1. Since the water pipe 2 is set on the top of the weight block 4, when the weight block 4 moves upward in the supporting tube 1, the water pipe 2 will be lifted up from the supporting tube 1, and the embedded plate 20 will be separated from the embedded groove 21;

[0038] As the weight block 4 is lifted, when it is lifted to the position of the set stopper 15, the water pipe 2 is lifted to the maximum height, and the first fixing rod 16 set on the stopper 15 will press the second fixing rod 17 set on the top of the baffle 5, so that the baffle 5 slides downward on the weight block 4. Because the baffle 5 is connected to the plug body through the connecting rod 9, as the baffle 5 moves downward, the plug body will be pulled out of the water inlet pipe 6. At this time, part of the water flow will enter the weight block 4 through the water inlet channel 14. The baffle 5 is not completely separated from the weight block 4, and most of the impact of the water pressure will still lift and stabilize the weight block 4.

[0039] Since a spiral water inlet channel 14 is provided in the water inlet pipe 6, the inflowing water has a certain disturbance when entering the weight block 4 through the spirally provided water inlet channel 14, and the blades 13 are provided in an arc shape and in the same direction as the spiral water inlet channel 14, so that the water flowing through the water inlet channel 14 can better impact the blades 13, and then the water flow is transported to the sprinkler head 3 through the water delivery pipe 2 for sprinkler irrigation, and the rotating rod 11 will drive the provided water delivery pipe 2 to rotate, so that the water delivery pipe 2 rotates, thereby increasing the area that can be covered by sprinkler irrigation;

[0040] After the sprinkler irrigation operation is completed, the water pump is turned off and the water flow in the supporting tube 1 is receded. At this time, the weight block 4 will drive the water pipe 2 to move into the supporting tube 1 under the action of gravity. When the weight block 4 returns to its original position, the embedded plate 20 will be embedded in the embedded groove 21, and the protective shell 19 can protect other components to prevent some debris from falling into the supporting tube 1 and affecting the drive of other components. When the weight block 4 moves downward, the stretched reset spring 18 needs to be reset. As the pressure of the first fixing rod 16 continues to decrease, the reset spring 18 will pull the second fixing rod 17 and the baffle 5, thereby reinserting the plug body into the water inlet pipe 6 through the baffle 5 for sealing.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
