Description

Technical Field

[0001] This utility model relates to the field of rice planting irrigation, and more specifically, to a rice planting irrigation device. Background Technology

[0002] Rice is a plant belonging to the genus Oryza of the family Poaceae. It originated in China and India and has a cultivation history of seven thousand years. As the staple food of nearly half of the world's population, rice can be classified into indica rice, japonica rice, glutinous rice, etc., and into conventional rice and hybrid rice according to the method of seed saving.

[0003] Irrigation is necessary during rice cultivation. Currently, most methods use a combination of floats and pressure sensors to monitor the water level in rice paddies. When the water level drops to a certain point, water pumps need to be turned on for irrigation. However, the floats, floating on the water surface, can be disturbed by weeds and floating debris in the paddy field, causing them to sink and press against the pressure sensors. The external controller receives the signal transmitted by the pressure sensors, processes the signal, and turns on the water pump, which can lead to misjudgments of the water level. Frequent starting and stopping of the water pumps affects the irrigation effect. How to invent a rice cultivation irrigation device to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rice planting irrigation device, which aims to improve the current method of using a combination of float and pressure sensor to detect the water level in rice fields. When the water level drops to a certain position, the water pump needs to be turned on for irrigation. However, the float floats on the water surface and is disturbed by weeds and floating objects in the rice field, causing the float to fall and squeeze the pressure sensor, which may lead to misjudgment of the water level and frequent start and stop of the water pump.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a rice planting irrigation device, including a support plate and a vertical column mounted on the support plate, and further including: an irrigation mechanism: the irrigation mechanism is mounted on the vertical column; a water level monitoring mechanism: the water level monitoring mechanism is slidably sleeved on the vertical column, the water level monitoring mechanism can detect the water level in the paddy field and can carry out timely irrigation; and a protective mechanism: the protective mechanism is slidably sleeved on the vertical column, the protective mechanism can protect the water level monitoring mechanism.

[0007] Preferably, the irrigation mechanism includes a water-collecting shell mounted on a vertical column, a water-transmitting pipe inside the vertical column, one end of the water-transmitting pipe being connected to the inside of the water-collecting shell, and a water pump connecting pipe connected to the other end of the water-transmitting pipe. Four sets of water outlet pipes are provided through the outer wall of the water-collecting shell, one end of each of the four sets of water outlet pipes is provided with a threaded connector, and a control valve is provided inside each of the four sets of water outlet pipes.

[0010] Preferably, both the inner walls of the second sliding sleeve and the first sliding sleeve are provided with sliders, and the side wall of the vertical column is provided with a groove, in which the sliders slide and connect.

[0011] Preferably, the support plate has barbed inserts at the bottom and multiple sets of stabilizing inserts at the bottom edge of the support plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up a protective mechanism, can drive the wire mesh cover to rise and fall under the action of the second sliding sleeve and the second fixing bolt. It can cover the float with the wire mesh cover, which can prevent weeds and floating objects in the paddy field from interfering with the float, thereby preventing misjudgment of water level, improving monitoring accuracy, and enabling accurate irrigation.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example, refer to Figures 1-5 A rice planting irrigation device includes a support plate 1 and a vertical column 4 mounted on the support plate 1. The support plate 1 has barbed rods 2 at its bottom and multiple sets of stabilizing rods 3 at its bottom edge. The barbed rods 2 and the multiple sets of stabilizing rods 3 work together to ensure the support plate 1 is stably supported on the rice paddy, guaranteeing the verticality of the vertical column 4. This improves the verticality of the float 502, allowing for better monitoring of the rice paddy water level and preventing misjudgments. The device also includes: an irrigation mechanism 7 mounted on the vertical column 4; a water level monitoring mechanism 5 slidably sleeved on the vertical column 4, capable of detecting the water level in the rice paddy and providing timely irrigation; and a protective mechanism 6 slidably sleeved on the vertical column 4, providing protection for the water level monitoring mechanism 5.

[0024] The irrigation mechanism 7 includes a water collection shell 702 mounted on a vertical column 4. A water delivery pipe 701 is installed inside the vertical column 4. One end of the water delivery pipe 701 is connected to the inside of the water collection shell 702, and the other end of the water delivery pipe 701 is connected to a water pump connection pipe 700. Four sets of water outlet pipes 703 are provided through the outer wall of the water collection shell 702. One end of each of the four sets of water outlet pipes 703 is provided with a threaded connector 704, and each of the four sets of water outlet pipes 703 is provided with a control valve 705.

[0025] It should be noted that: the water pump connecting pipe 700 is connected to an external water pump. When the water level drops, the pressure sensor 507 will be squeezed, so the external controller will receive the signal transmitted by the pressure sensor 507, process the signal, and turn on the external water pump (the external controller is electrically connected to the pressure sensor 507 and the external water pump, so the external controller can receive and process the signal, which is the prior art). The external water pump will send water through the water pump connecting pipe 700 and the water delivery pipe 701 into the water collection shell 702. The threaded connector 704 is threadedly connected to the external irrigation water pipe. Then the control valve 705 is opened, and water will enter the external irrigation water pipe for irrigation.

[0026] The water level monitoring mechanism 5 includes a first sliding sleeve 500 slidably sleeved on the outer wall of a vertical column 4. A first fixing bolt 501 is provided through the outer wall of the first sliding sleeve 500. A sleeve 508 is provided on the outer wall of the first sliding sleeve 500. A movable plate 505 is slidably connected inside the sleeve 508. A float 503 is provided at the top of the movable plate 505. One end of the float 503 passes through the top of the sleeve 508 and is connected to a float ball 502 provided on the outside. A spring 504 is sleeved on the outer wall of the float 503. A pressing rod 506 is provided at the bottom of the movable plate 505. A pressure sensor 507 is provided at the bottom of the sleeve 508.

[0027] It should be noted that the position of the float 502 can be adjusted using the first sliding sleeve 500 and the first fixing bolt 501. In the initial state, the float 502 can be level with the water surface of the paddy field. When the water level drops, the float 502 moves downward, which can drive the float rod 503 and the movable plate 505 to move downward. The movable plate 505 compresses the spring 504, and the movable plate 505 drives the compression rod 506 to move downward to compress the pressure sensor 507. Thus, the pressure sensor 507 can transmit the signal to the external controller.

[0028] The protective mechanism 6 includes a second sliding sleeve 603 that is slidably fitted onto the outer wall of the vertical column 4. Both the second sliding sleeve 603 and the first sliding sleeve 500 have sliders on their inner walls. The side wall of the vertical column 4 has a groove 8, in which the sliders slide and connect, thereby making the second sliding sleeve 603 and the first sliding sleeve 500 move more stably up and down on the outer wall of the vertical column 4. A second fixing bolt 604 is provided through the outer wall of the second sliding sleeve 603. A connecting rod 602 is provided on the outer wall of the second sliding sleeve 603. A connecting plate 601 is provided at one end of the connecting rod 602. A wire mesh cover 600 is provided at the bottom of the connecting plate 601.

[0029] It should be noted that the second sliding sleeve 603 moves up and down on the vertical column 4, which can adjust the height of the wire mesh cover 600 so that the wire mesh cover 600 covers the float 502. Then, the second fixing bolt 604 is used to lock the position of the second sliding sleeve 603 to ensure the stability of the height of the wire mesh cover 600. The wire mesh cover 600 adopts a fine mesh design, which can block weeds and floating objects while allowing water to flow freely. The wire mesh cover 600 is cylindrical in shape and matches the float 502 to ensure complete coverage. This allows for real-time feedback of the actual water level and avoids over- or under-irrigation due to misjudgment.

[0030] The working principle of this rice planting irrigation device is as follows: With the cooperation of the barbed rods 2 and multiple sets of stabilizing rods 3, the support plate 1 can be stably supported on the paddy field, ensuring the verticality of the vertical column 4. The position of the float 502 can be adjusted using the first sliding sleeve 500 and the first fixing bolt 501, so that the float 502 is initially level with the water surface of the paddy field. Then, the position of the second sliding sleeve 603 is adjusted using the second sliding sleeve 603 and the second fixing bolt 604, ensuring that the wire mesh cover 600 and the float 502 provide protection, preventing interference from debris on the water surface.

[0031] As the water level drops, the float 502 moves downward, causing the float rod 503 and the movable plate 505 to move downward. The movable plate 505 compresses the spring 504, which in turn causes the compression rod 506 to move downward and compress the pressure sensor 507. This allows the pressure sensor 507 to transmit a signal to the external controller. The external controller receives and processes the signal from the pressure sensor 507, then turns on the external water pump. The external water pump draws water through the pump connection pipe 700 and the water delivery pipe 701 into the water collection shell 702. The threaded connector 704 is threadedly connected to the external irrigation water pipe. Then, the control valve 705 is opened, allowing water to enter the external irrigation water pipe for irrigation, thus irrigating the rice.

[0032] It should be noted that the model and specifications of the pressure sensor, external water pump and external controller need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
