Description

Technical Field

[0001] The utility model relates to the field of farmland irrigation, and more specifically, to a farmland irrigation device capable of adjusting the drainage volume. Background Art

[0002] Farmland irrigation is crucial for agricultural production, which affects the growth and yield of crops. With the advancement of agricultural modernization in China, farmland irrigation technology has been continuously improved. However, there are still some problems in the actual application of existing farmland irrigation devices, such as non-adjustable drainage volume, low water utilization rate, complex operation, etc. There is an urgent need for a farmland irrigation device capable of adjusting the drainage volume.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number 202122604093.7 discloses a farmland water conservancy irrigation device, including a water storage tank. The bottom of the water storage tank is fixedly connected with an irrigation tank. A round hole is opened on the left side of the inner bottom surface of the water storage tank. A conical hole matching the round hole is opened on the left side of the inner top surface of the irrigation tank. A movable rod is movably inserted between the round hole and the conical hole, but there are still the following defects:

[0004] (1) In the above patent document, a compression spring and an electric telescopic rod are used as the power source for the device to pump water outwards. However, due to the large difference in elastic force between the starting end and the ending end of the compression spring during the rebound stroke, the device pumps water outwards not smoothly and the water pressure is uncontrollable, resulting in poor farmland irrigation effect;

[0005] In the above patent document, the scale line on the outer wall of the sliding rod is used as the standard for detecting the drainage volume. However, the specific detection target of the scale line is the internal volume of the irrigation tank. If there are air bubbles in the irrigation tank, the detection of the drainage volume will be inaccurate.

[0006] Therefore, we make improvements and propose a farmland irrigation device capable of adjusting the drainage volume. Utility Model Content

However, due to the large difference in elastic force between the starting end and the ending end of the compression spring during the rebound stroke, the device pumps water outwards not smoothly and the water pressure is uncontrollable, resulting in poor farmland irrigation effect. Also, the scale line on the outer wall of the sliding rod is used as the standard for detecting the drainage volume. However, the specific detection target of the scale line is the internal volume of the irrigation tank. If there are air bubbles in the irrigation tank, the detection of the drainage volume will be inaccurate.

[0008] To achieve the above utility model purpose, the present utility model provides the following technical solutions:

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0030] As shown in Figure 1 , Figure 2 and Figure 3 shown, this embodiment provides a farm irrigation device capable of adjusting the drainage volume, including a sealed water tank 1 and a mounting bracket 11 fixedly connected to the bottom wall of the sealed water tank 1. It further includes:

[0031] A pressurizing assembly, fixedly connected to the outer wall of the sealed water tank 1, for pressurizing the sealed water tank 1. Among them, the pressurizing assembly includes an air pump bracket 2 fixedly connected to the outer wall of the sealed water tank 1, a supercharging air pump 21 fixedly connected to the inner wall of the air pump bracket 2, an air duct 22 fixedly connected to the top wall of the supercharging air pump 21, and a one-way air valve 23 fixedly connected to the inner wall of the air duct 22.

[0032] A water delivery assembly, fixedly connected to the top wall of the sealed water tank 1, for replenishing water into the sealed water tank 1;

[0033] A drainage assembly, fixedly connected to the bottom wall of the sealed water tank 1, for quantitatively draining water and irrigating farmland;

[0034] An observation assembly, arranged on the outer wall of the sealed water tank 1, for observing the water level and detecting the drainage volume;

[0035] A balance assembly, fixedly connected to the top wall of the sealed water tank 1, for balancing the internal and external pressures when replenishing water;

[0036] Start the supercharging water pump 31 to pressurize the sealed water tank 1, and at the same time observe the air pressure in the sealed water tank 1 through the pressure gauge 61 to keep the air pressure level in the sealed water tank 1 within the set range all the time.

[0037] As shown in Figure 1 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the water delivery assembly includes a water pump 31 fixedly connected to the top wall of the sealed water tank 1, a water suction pipe 3 fixedly connected to the side wall of the water pump 31, a water delivery pipe 32 fixedly connected to the side wall of the water pump 31, and a one-way sealing valve 33 fixedly connected to the inner wall of the water delivery pipe 32. The water pumps 31 are symmetrically distributed about the central axis of the sealed water tank 1. The water pumps 31 are connected to the inside of the sealed water tank 1 through the water delivery pipe 32 and the one-way sealing valve 33. First, open the pressure relief valve 6 and start the water pump 31. The water pump 31 transports water into the sealed water tank 1 through the water suction pipe 3 and the water delivery pipe 32 to complete the water filling work of the sealed water tank 1.

The sealed water tank 1 is internally connected to the U-shaped pipe 5, and the U-shaped pipe 5 is fixedly connected to the drain valve 51. When the drain valve 51 is opened, since the U-shaped pipe 5 is internally connected to the sealed water tank 1 to form a communicating vessel structure and the pressurizing air pump 21 continuously pressurizes the sealed water tank 1 during drainage, the water in the sealed water tank 1 can be discharged uniformly through the drain valve 51 and the drain pipe 52.

When the drainage volume of the device reaches the expected value, the drain valve 51 and the pressurizing air pump 21 are closed to complete the farmland irrigation work with controllable drainage volume.

[0040] As Figure 1 , Figure 3 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the balance assembly includes a pressure relief valve 6 fixedly connected to the top wall of the sealed water tank 1 and a pressure gauge 61 provided on the top wall of the sealed water tank 1. The pressure gauge 61 extends inward through the top wall of the sealed water tank 1. When adding water to the sealed water tank 1, the pressure relief valve 6 can be opened to ensure the smoothness of water addition.

Then, close the pressure relief valve 6. The one-way sealing valve 33 in the water delivery pipe 32 ensures the airtightness of the sealed water tank 1. Start the booster water pump 31 to pressurize the sealed water tank 1. At the same time, observe the air pressure in the sealed water tank 1 through the pressure gauge 61 to keep the air pressure level in the sealed water tank 1 always within the set range. When it is necessary to drain water to irrigate the farmland, open the drain valve 51. Since the U-shaped pipe 5 is connected to the inside of the sealed water tank 1 to form a communicating vessel structure and the booster air pump 21 continuously pressurizes the sealed water tank 1 during drainage, the water in the sealed water tank 1 can be discharged uniformly through the drain valve 51 and the drain pipe 52. Control the water pressure and flow rate of drainage by adjusting the valve opening of the drain valve 51 and the air pressure in the sealed water tank 1. When the device is used for draining and irrigating the farmland, the drainage volume of the device can be detected through the transparent observation window 4 and the water level scale line 41.
