Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically a small-scale farmland irrigation device. Background Technology

[0002] Small-scale farmland irrigation projects are a series of projects built primarily to solve the irrigation problems of arable land. These projects play a crucial role, not only in improving irrigation reliability but also in responding to disasters such as droughts. For example, while their effectiveness may be less noticeable in years of good weather, a well-developed farmland irrigation system is essential for drought relief and disaster mitigation during droughts. They ensure the normal growth of crops under arid conditions, thereby guaranteeing agricultural yields and food security.

[0003] A search revealed a utility model patent with publication number CN110199837A, which discloses a small-scale farmland irrigation device. The device includes a rotating micro-sprinkler, a pressure-reducing pipeline, a capillary connector, an angle adjuster, and a support pole. The support pole is vertically inserted into the farmland. The pressure-reducing pipeline is fixedly connected to the support pole via the angle adjuster. The capillary connector is fixedly installed at the bottom of the pressure-reducing pipeline, and the rotating micro-sprinkler is fixedly installed at the top. The water passages of the capillary connector, the pressure-reducing pipeline, and the rotating micro-sprinkler are sequentially connected from bottom to top. The pressure-reducing pipeline contains a high-pressure reducing mechanism and a low-pressure reducing mechanism. This irrigation device is suitable for mountainous areas and terraced fields, has a wide input water pressure range, a long service life, low production costs, and low maintenance difficulty.

[0004] However, the above design still has shortcomings. Although the water channels of the pressure-reducing pipeline and the rotating micro-sprinkler are connected sequentially from bottom to top, and the pressure-reducing pipeline is equipped with a high-pressure reducing mechanism, making the water tower of this device have a wide range and convenient maintenance, for some farmland, where automated sprinkler irrigation covers a large area and no longer requires manual support, greatly reducing labor and improving efficiency, in addition, due to weather conditions, the inside may freeze in winter, affecting the operation. Therefore, we propose a small farmland irrigation device to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a small farmland irrigation device, including a base 1 and a water tank 4. A motor 24 is connected to the inner bottom wall of the base 1. A straight pipe 9 is connected to the output end of the motor 24. The output end of the motor 24 is rotatably connected to the end of the straight pipe 9 near the base 1. A cover plate 5 is connected to the upper surface of the water tank 4. A motor 6 is connected to the upper surface of the cover plate 5. A rotating shaft 19 is connected to the inner top wall of the cover plate 5. The output end of the motor 6 passes through the outer wall of the cover plate 5 and is rotatably connected to the rotating shaft 19. A set of actuating paddles 20 are installed on the outer surface of the rotating shaft 19.

[0022] The base 1 has a traction ring 3 connected to its left side, which allows the entire device to move between different positions by traction. This is very convenient for farmland that needs to be irrigated in different plots. The base 1 has two support frames 15 installed on its bottom surface, and the motor 6 has an adjusting valve 10 connected to its back.

[0023] Each support frame 15 has a bearing 14 rotatably connected to its inner wall. The rotatable connection of the bearing 14 can significantly reduce the friction between the wheel 2 and the support frame 15, making the wheel 2 rotate more smoothly. Each bearing 14 has a wheel 2 installed at both ends. Since the device can be moved easily, farmers do not need to spend a lot of effort to move the irrigation device, thus reducing physical labor.

[0024] The upper surface of the base 1 is connected to a baffle 13, which can protect the internal components (such as motor 6, circuits, etc.) and prevent external forces from directly acting on these sensitive parts. The upper surface of the baffle 13 is connected to two support plates 12, and the side of the two support plates 12 that is close to each other is connected to a fixing block 11 along with the outer surface of the straight tube 9.

[0025] The base 1 has a connecting plate 17 connected to its back, and a regulator 18 is connected to the back of the connecting plate 17. The regulator 18 and the control box 16 are integrated on the connecting plate 17, which allows for centralized control and management of the irrigation device and facilitates user operation. The control box 16 is connected to the back of the connecting plate 17.

[0026] The upper surface of the straight pipe 9 is connected to the connecting block 7, and the right side of the connecting block 7 is hinged to the water nozzle 8. The water nozzle 8 is connected by a hinge, which can flexibly adjust the direction of water spraying to meet the irrigation needs of different crops.

[0027] The upper surface of the base 1 is connected to a water pump 22. The left side of the water pump 22 is connected to an inlet pipe 21. The end of the inlet pipe 21 away from the water pump 22 passes through the outer wall of the water tank 4 and is connected to the inside of the water tank 4. The right side of the water pump 22 is connected to an outlet pipe 23. The end of the outlet pipe 23 away from the water pump 22 passes through the outer wall of the straight pipe 9 and is connected to the inside. Since the water pump 22, the inlet pipe 21 and the outlet pipe 23 are all integrated on the base 1, the whole device is easy to move and install, and is suitable for use in different plots of land.

[0028] Working principle: During use, the operator connects the tractor to the traction ring 3, and then the device is moved by the action of the wheels 2. Then the water pump 22 starts to draw water from the water tank 4 and pumps it into the straight pipe 9 through the outlet pipe 23. The motor 24 starts and adjusts the half shaft rotation through the regulator 18, driving the straight pipe 9, connecting block 7 and spray nozzle 8 to spray in a fan shape for fully automatic large-area coverage. The hinge between the spray nozzle 8 and the connecting block 7 can adjust the spray height. Weather conditions may cause internal icing. The motor 6 drives the rotating shaft 19 and the actuating paddle 20 installed on the outer surface of the rotating shaft 19 to keep the water in the water tank 4 flowing, avoiding internal icing due to weather conditions, which would affect the operation and damage the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
