Description

Technical Field

[0001] The utility model belongs to the technical field of field irrigation, in particular to a hanging type sprinkler. Background Art

[0002] In the process of irrigation, if there is a water source close to the farmland, such as a river, it is often possible to use the water from the river directly for irrigation. This irrigation method has the characteristics of using local materials and high energy efficiency.

[0003] Currently, when drawing water from rivers for irrigation, the method used is to install a suction pipe on a water pump, place the suction pipe in the river, and then the water pump uses the suction pipe to suck water from the river for irrigation. This method often requires manual operation to install and remove the suction pipe and manually install the suction pipe in the river.

[0004] The disadvantages of this method are: water shortage and unfixed position when irrigating fields; artificial placement of the water absorption part is not easy to operate due to the slippery and steep river slope and the danger of the operator being caught in the river; the sprinkler is large in size and heavy in weight, not easy to move and inefficient.

[0005] In order to solve the above technical problems, a movable irrigation device is currently provided. The device can be moved in the field under the drive of a tractor. The water pump and the spray gun are all on the vehicle body. The tractor can drive the vehicle body to move. However, the water pipe needs to be placed at the water source. In this way, as the vehicle body moves, the water pipe will always be in the water source, continuously absorbing water to achieve irrigation. Figure 1 shown.

[0006] In addition, the patent announcement number: CN220987003U discloses a wheat irrigation device, including a water tank, an upper end surface of the water tank is installed with a motor, the output end of the motor passes through the upper end surface of the water tank and is installed with a rotating shaft, the outer side wall of the rotating shaft is movably connected with a filter installed on the inner side wall of the water tank, when the device is used, water in the canal or river can be pumped into the interior of the water tank, and then the filter can filter the water in the water tank, and by starting the second water pump, the water spray pipe is used to spray water to irrigate the wheat, and during the irrigation process, the carriage is pushed to move by the bracket to drive the water spray pipe to move, thereby effectively improving the irrigation speed of the wheat; after the irrigation is used, the impurities on the filter are cleaned by rotating the brush plate, and then the valve on the discharge pipe is opened. During the rotation of the spiral rod, the impurities at the bottom of the water tank are transported out from the discharge pipe, thereby achieving the effect of automatically cleaning the filtered impurities, effectively saving manual labor.

[0007] The suction pipe draws water from the canal into the water tank, and the vehicle drives the sprinkler pipe to move, achieving wide-area irrigation during movement. This method is relatively efficient. However, the following problems still exist: this method still requires manual placement of the suction pipe into the water source, which is still labor-intensive and prone to danger, and does not fundamentally solve the technical problems.

DETAILED DESCRIPTION

[0026] Example 1, a suspended sprinkler. In this embodiment, the sprinkler itself has no power source, and its power source comes from the suspended tractor. The tractor is a mature existing technology, and the tractor can be directly connected to the sprinkler.

[0027] This sprinkler, such as Figures 2 to 5 As shown, it includes a vehicle body 1, which can be moved between fields under the drive of a tractor;

[0028] In order to achieve the connection between the vehicle body 1 and the tractor, a connecting plate 20 is provided at the front of the vehicle body 1. The connecting plate 20 is provided with a connecting hole. When in use, the tractor and the connecting plate 20 are connected by a connecting pin.

[0029] To support vehicle body 1 when not in use, a clamping plate 16 is provided on vehicle body 1. Clamping plate 16 holds a support rod 3, which is vertically arranged and provided with multiple holes 4, each of which is vertically distributed. When in use, support rod 3 is connected to clamping plate 16 via bolts and holes 4, providing support for the front of vehicle body 1 when stationary. Specifically, the support rod 3 can be connected to the tractor by connecting the appropriate holes 4 to the tractor as needed.

[0030] A movable wheel 2 is provided at the rear of the vehicle body 1 and is connected to the vehicle body 1 via a mounting rod 13. To adjust the height of the vehicle body 1, a connecting base 14 is provided on the vehicle body 1. The connecting base 14 has a plurality of mounting holes 15 arranged in an arc shape, each at a different height. Thus, the movable wheel 2 can be mounted on the vehicle body 1 by simply bolting the mounting rod 13 to the appropriate mounting hole 15.

[0031] In summary, the front of the vehicle body 1 is connected to the tractor and the connecting plate 20 via a connecting pin; the rear of the vehicle body 1 is connected to the mounting rod 13 and the mounting hole 15 at an appropriate height, achieving an adjustable connection at the rear of the vehicle body 1, thereby allowing the vehicle body 1 to travel between fields. When the vehicle body 1 is not in use, the tractor needs to be disconnected from the vehicle body 1. In this case, to support the front of the vehicle body 1, the support rod 3 is connected to the clamping plate 16. When in use, the clamping plate 16 is connected to the appropriate hole 4 on the support rod 3 as needed. The purpose is that the support rod 3 can keep the vehicle body 1 in a basically horizontal state.

[0032] A water pump 5 is mounted on the vehicle body 1. In this embodiment, the tractor's PTO output shaft is connected to the power shaft of the water pump 5 to power the water pump 5, ensuring its proper operation. This embodiment directly utilizes the tractor's power, eliminating the need for an additional power source on the vehicle body 1. This reduces both equipment costs and the overall weight and cost of the sprinkler. The tractor's PTO output shaft is a mature prior art feature and is not an improvement of this embodiment.

[0033] To facilitate the installation of the water pump 5, a horizontally arranged mounting plate 12 is provided on the vehicle body 1, and the water pump 5 is located on the mounting plate 12; a screw 17 is provided on the vehicle body 1 along the length direction of the vehicle body 1, and the screw 17 is arranged horizontally; the screw 17 drives the mounting plate 12 to move back and forth on the vehicle body 1.

[0034] In this embodiment, the screw 17 is manually actuated. By rotating the screw 17, the user can move the mounting plate 12 forward and backward on the vehicle body 1. The specific implementation is based on mature prior art and will be briefly described below: a nut is threaded onto the screw 17, a slider is connected to the nut, and the mounting plate 12 is connected to the slider; a slideway is provided on the vehicle body 1 to match the slider, and the slider slides within the slideway.

[0035] By moving the water pump 5 forward and backward on the vehicle body 1 , it is advantageous to fine-tune the position of the water pump 5 , making the use more flexible.

[0036] The water inlet of the water pump 5 is connected to a suction pipe 9, the end of which is connected to a suction check valve 10. Water flows through the suction check valve 10 in the following direction: water can enter the suction check valve 10 from the bottom of the suction check valve 10, then enter the suction pipe 9 through the suction check valve 10. Water in the suction pipe 9 cannot pass through the suction check valve 10 and exit the suction check valve 10. The suction check valve 10 used in this embodiment is a mature prior art, and this embodiment 1 does not involve any improvement thereto.

[0037] When in use, the water suction pipe 9 is placed in a water source such as a river, and water is sucked into the water suction pipe 9 through the water suction one-way valve 10 and then enters the water pump 5. In this embodiment, the water in the water suction pipe 9 is prevented from flowing downward by using the water suction one-way valve 10. In this way, when the water pump 5 is restarted, there is no need for water in the water tank to enter the water inlet of the water pump. Water only needs to be passed into the water pump 5 when it is started for the first time.

[0038] In order to facilitate the placement of the suction pipe 9 into a water source such as a river, a support frame 8 is provided on the vehicle body 1. In order to improve the stability of the support frame 8, the support frame 8 is triangular. When in use, the suction pipe 9 can be connected to the support frame 8.

[0039] To facilitate the connection of the support frame 8, a horizontally rotatable turntable 221 is provided on the vehicle body 1. The turntable 221 is provided with a socket 222. A pin is inserted into the socket 222 and can be inserted into the vehicle body 1. The pin can be used to fix the turntable 221 after rotation. A first mounting seat 23 is provided on the turntable 221. In this way, the first mounting seat 23 can rotate horizontally with the turntable 221. A horizontally arranged first shaft 24 is rotatably provided on the first mounting seat 23. The support frame 8 is connected to the first shaft 24. In this way, as the first shaft 24 rotates, the support frame 8 can rotate in the vertical direction.

[0040] To drive the vertical rotation of the support frame 8, a driving hydraulic cylinder 11 is also rotatably mounted on the turntable 221. The distal end of the driving hydraulic cylinder 11 is rotatably connected to the support frame 8. When the turntable 221 rotates, the support frame 8 and the driving hydraulic cylinder 11 rotate together horizontally with the rotation of the turntable 221. Specifically, a second mounting base 25 is mounted on the turntable 221. A second shaft 26 is mounted horizontally on the second mounting base 25. The second shaft 26 is rotatably mounted on the second mounting base 25, and the driving hydraulic cylinder 11 is connected to the second shaft 26.

[0041] When the driving hydraulic cylinder 11 is extended, it will drive the support frame 8 to rotate in the vertical direction. Since the water suction pipe 9 is connected to the support frame 8, the rotation of the support frame 8 will drive the water suction pipe 9 to rotate in the vertical direction. The end of the support frame 8 shows an arc-shaped walking trajectory from high to low, so that the support frame 8 can fall back from a high place to a low place. In this way, the water suction pipe 9 can be placed in a water source such as a river, or retracted from a water source such as a river.

[0042] When the hydraulic cylinder 11 is shortened, the support frame 8 is driven to rotate in the vertical direction, driving the suction pipe 9 from a low position to a high position, thereby realizing the automatic retraction process of the suction pipe 9. In this embodiment, the length of the suction pipe 9 is relatively long, ensuring that the rotation of the support frame 8 is not affected.

[0043] In summary, by driving the hydraulic cylinder 11 to drive the support frame 8 to rotate in the vertical direction, the water suction pipe 9 is placed into the water source or retracted from the water source.

[0044] In addition, by providing a turntable 221, the support frame 8 can be rotated in the horizontal direction, and the water suction pipe 9 can be rotated to the left or right side of the vehicle body 1 according to the location of the water source, thereby improving convenience during use.

[0045] When in use, the water pump 5 sucks the water in the water suction pipe 9 to the water outlet of the water pump 5. The water outlet of the water pump 5 is connected to the water outlet pipe 27, and the spray gun 7 is connected to the end of the water outlet pipe 27. The spray gun 7 is set to be tilted upward, so that the water from the water pump 5 can be sprayed out from the spray gun.

[0046] The spray gun used in this embodiment is a commercially available product, and the spray gun 7 can achieve irrigation within its range. Among them, the spray gun selected is: American Toro P2M piston-driven spray gun, wherein the water outlet of the spray gun 4 is tilted upward by 30 to 45 degrees.

[0047] As an alternative to this embodiment, a water tank 6 is provided on the vehicle body 1, and the water tank 6 is connected to the water inlet of the water pump 5 via a lower connecting pipe 19. Connecting the lower connecting pipe 19 to the water inlet of the water pump 5 allows water to flow into the water inlet of the water pump 5 under the action of gravity, thereby ensuring the normal operation of the water pump 5 and reducing energy consumption. During use, a valve is provided on the lower connecting pipe 19. When needed, the valve is opened to allow water to flow to the water inlet of the water pump 5. When not needed, the valve can be closed. The valve is a commercially available product and no improvement is required. A manual valve can be used.

[0048] The water outlet of water pump 5 is connected to water tank 6 via upper connecting pipe 18, which is also equipped with a valve. This allows water pump 5 to be used to fill water tank 6. When refilling is needed, simply open the valve. The valve is not shown in the figure, and only a section of upper connecting pipe 18 is shown; its actual length is required to connect the water pump outlet to the water tank.

[0049] The working process is as follows: the tractor is driven to the vehicle body 1, and the support rod 3 is connected to the tractor with bolts; the mounting rod 13 is connected to the vehicle body 1 with bolts to realize the installation of the moving wheel 2 and the vehicle body 1; after the installation is completed, the PTO output shaft of the tractor is connected to the water pump 5.

[0050] The tractor moves to move the vehicle body 1 to a suitable position; the turntable 221 is rotated to make the water suction pipe 9 face the water source, driving the hydraulic cylinder 11 to extend, so that the support frame 8 is changed from a vertical state to a horizontal state, so that the end of the water suction pipe 9 extends into the water source; the water pump 5 is started, and the water pump 5 sucks water into the water suction pipe 9, and the water comes out from the water pump 5, enters the water outlet pipe 27 after coming out of the water pump 5, and is sprayed out from the spray gun after passing through the water outlet pipe 27.

[0051] It should be noted that when the water pump 5 is used for the first time, there is no water at the water inlet of the water pump 5 and the water pump 5 cannot be started. At this time, the lower connecting pipe 19 of the water tank 6 inputs water into the water inlet of the water pump 5 to help start the water pump 5; the water in the outlet pipe 27 is sprayed out from the spray gun 7 and sprayed into the field; the tractor drives the vehicle body 1 to move, so that the water suction pipe 9 moves with the vehicle body 1 to absorb water; the spray gun 7 sprays water into the field as the vehicle body 1 moves.

[0052] When the water pump 5 is not used for the first time, the water left after the last operation of the water pump 9 will remain in the water suction pipe 9 due to the action of the water suction one-way valve 10, and there is no need to use the water tank. Only when the water pump 5 is used for the first time and there is no water in the water suction pipe 9, is it necessary to allow the water in the water tank to enter the water inlet of the water pump.

[0053] When in use, the support frame 8 can be rotated using the turntable 221 according to whether the water source is on the left or right side of the vehicle body 1, so that the position of the water suction pipe 9 is appropriate. After the turntable 221 rotates, the pin shaft is used to fix the turntable 221.

[0054] After the irrigation is completed, the hydraulic cylinder 11 is driven to shorten, so that the support frame 8 is transformed from a horizontal state to a vertical state, driving the water suction pipe 9 out of the water source, and the water suction pipe 9 can be collected.

[0055] Example 2. This example differs from Example 1 in that a flow valve, a flow sensor, and a pressure sensor are installed on the outlet pipe 27. The signal outputs of the flow sensor and pressure sensor are connected to the signal input of a controller, which is connected to an Internet of Things card. The flow sensor and pressure sensor respectively collect flow and pressure information in the outlet pipe and transmit this information to the controller, which then transmits the information outward via the Internet of Things card. The flow valve controls the flow of water through the outlet pipe 27.

[0056] In this way, when water passes through the outlet pipe, the flow sensor and pressure sensor respectively collect flow rate information and water pressure information, and transmit the collected information to the controller. The controller can then transmit the information through the Internet of Things card, thereby enabling the background to view the operating parameters of the irrigation machine. In this way, when the water pump is working, it draws water into the water intake pipe 9, enters the water pump, and then flows out of the water pump and enters the outlet pipe 27. The flow sensor and pressure sensor in the outlet pipe 27 respectively detect the flow signal and pressure signal, and transmit the flow signal and pressure signal using the Internet of Things card. The water from the outlet pipe 27 enters the spray gun and is sprayed out from the spray gun.

[0057] Example 3, this example is different from Example 1 in that: Figure 6 As shown, the water suction one-way valve 10 includes a valve body 28 and a valve core 29. The valve core 29 is rotatably disposed within the valve body 28. A volute spring is connected to the valve core 29. After the valve core 29 rotates under the action of water, it is reset under the action of the volute spring. A stopper 30 is provided below the free end of the valve core 29. The stopper 30 prevents the valve core 29 from rotating downward and only allows it to rotate upward, thereby achieving a one-way flow. At the same time, a sealing ring is provided on the valve core 29 to ensure the seal between the valve core 29 and the valve body 28. When water is above the valve core 29, the stopper 30 intercepts the water. When water flows from below the valve core 29, the water pressure causes the valve core 29 to rotate relative to the valve body 28, allowing water to enter the valve core 29.

[0058] As a supplement to this embodiment, after the centrifugal pump 20 stops working, since the water suction one-way valve 10 is a one-way valve, the water suction pipe 9 is filled with water. In cold weather, in order to prevent the water in the water suction pipe 9 from freezing and causing damage, a wrench 31 is provided on the water suction one-way valve 10. The wrench 31 can drive the one-way valve to open in the reverse direction, thereby allowing the water in the water suction pipe 9 to flow out. This method can, on the one hand, prevent the water suction pipe 9 from freezing, thereby improving the convenience during use.

[0059] To achieve this effect, the stopper 30 is connected to the wrench 31; a horizontally arranged hole 19 is provided in the valve body 28, and the hole 19 is arranged toward the stopper 30; the stopper 30 is slidably arranged at the hole 19 in the horizontal direction, and when the wrench 31 drives the stopper 30 to slide into the hole 19, the stopper 30 cannot block the rotation of the valve core 29, so that under the action of water, the valve core 29 rotates downward, and water comes out of the suction pipe 9. When the water has come out, the valve core 29 returns to a horizontal state under the action of the volute spring, and then the stopper 30 is pushed out of the hole 19 to block the rotation of the valve body 28.

[0060] The utility model discloses a suspended irrigation machine, which can automatically put the water suction pipe 9 into the water source, or take the water suction pipe 9 out of the water source. The design is ingenious and reduces the labor intensity. At the same time, the water suction pipe 9 can be freely rotated according to the location of the water source, which is more flexible to use and greatly improves the convenience of irrigation in the wild field.
