Abstract
Description
Technical Field
[0001] This application relates to the field of sunflower cultivation technology, specifically to an irrigation device for sunflower cultivation. Background Technology
[0002] Sunflower, also known as the morning glory or sunflower, is an annual herbaceous plant belonging to the genus Helianthus in the family Asteraceae. Native to North America, it is now widely cultivated in temperate and tropical regions worldwide, serving as both an important oil crop and a popular ornamental plant.
[0003] Sunflower irrigation methods are diverse, including slow-drip irrigation, drip irrigation, and furrow irrigation. Currently, sunflower irrigation is increasingly showing a trend towards diversification, precision, and water conservation, especially driven by water scarcity and the need for saline-alkali land improvement, leading to continuous optimization of irrigation technologies. Among these, integrated water and fertilizer irrigation is a promising method; however, existing integrated water and fertilizer irrigation systems suffer from drawbacks such as large size and high cost, and require dedicated water supply rooms for installation. For some areas with small planting areas, the cost outweighs the benefits, hindering its effective promotion. Utility Model Content
[0004] In view of the above problems, this application provides an irrigation device for sunflower planting, which is small in size and easy to move, so that it can meet the needs of small-area planting areas.
[0005] According to one aspect of the embodiments of this application, an irrigation device for sunflower cultivation is provided. The irrigation device for sunflower cultivation includes a mixing tank, a PLC control box, and a buffer tank. The mixing tank has a feeding port at its top and a stirring device inside. A first water pump and a second water pump are located on one side of the mixing tank. The outlet of the first water pump is connected to the top of the mixing tank via a pipe, and the bottom of the mixing tank is connected to the inlet of the second water pump. There are two buffer tanks. The outlet of the second water pump is connected to a diversion pipe, which is connected to the top of the two buffer tanks respectively via two first solenoid valves. A third water pump is located on one side of the buffer tank. The inlet of the third water pump is connected to a mixing pipe, which is connected to a first inlet pipe and a second inlet pipe via a three-way diversion valve. The two buffer tanks are connected to the first inlet pipe via second solenoid valves. The outlet of the third water pump is connected to an irrigation water pipe. The second inlet pipe and the inlet of the first water pump both extend to a water source.
[0006] In some embodiments, a high-point liquid level sensor and a low-point liquid level sensor are respectively installed inside the buffer tank from top to bottom, and the high-point liquid level sensor, the low-point liquid level sensor, and the first solenoid valve are all electrically connected to the PLC control box.
[0007] In some embodiments, a glass tube level gauge is connected to one side of the buffer tank.
[0008] In some embodiments, the top of the buffer tank is connected to a pressure regulating pipe, and the other end of the pressure regulating pipe is connected to the top of the mixing tank.
[0009] In some embodiments, a base is included, on which the mixing tank, the buffer tank, and the PLC control box are all disposed. A strip-shaped mounting plate is provided on the top of the base, and threaded holes are provided on the mounting plate. The buffer tank is connected to the mounting plate by a screw.
[0010] In some embodiments, the base has a plurality of support feet hinged to its bottom for support on the ground.
[0011] The beneficial effects of this application are as follows: By incorporating a mixing tank, a buffer tank, a first water pump, a second water pump, and a third water pump, irrigation water can be introduced into the mixing tank for mixing to form a mixed liquid. A three-way diversion valve controls the water inlet ratio of the first and second inlet pipes, ensuring that the fertilizer concentration in the irrigation water pumped out by the third water pump is controllable and within a reasonable range. The two buffer tanks are used alternately; one receives liquid from the mixing tank while the other supplies water to the third water pump. This ensures continuous operation of the equipment and allows for continuous irrigation. Even when the mixed liquid in the mixing tank is depleted, the buffer tank retains some liquid, allowing the equipment to continue operating normally during the next mixing process. This equipment is compact, easy to move, and suitable for small-scale sunflower planting areas.

[0020] For details, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the device provided in an embodiment of this application. Figure 2 This is a structural schematic diagram of the device as provided in an embodiment of this application from another perspective. Figure 3This is a schematic diagram of the main structure of the equipment provided in this application embodiment. The irrigation device 100 applied to sunflower planting includes a mixing tank 110, a PLC control box 120, and a buffer tank 130. The mixing tank 110 is used to stir and mix irrigation water and corresponding fertilizers, so that solid granular fertilizers dissolve in the water to form a mixed liquid. The PLC control box 120 is used to control components such as the first solenoid valve 152 and the second solenoid valve 165 after electrical connection. The buffer tank 130 is used to receive the mixed liquid that has been mixed in the mixing tank 110. The top of the mixing tank 110 is provided with a feeding port 111, and a stirring device is provided inside. During operation, water can be injected into the mixing tank 110 by a first water pump 140. When the water level reaches a certain level, the operator can put the fertilizer into the mixing tank 110 through the feeding port 111, and then turn on the stirring device to stir and mix. The stirring device can be composed of a motor, a stirring shaft, stirring blades, etc. A first water pump 140 and a second water pump 150 are installed on one side of the mixing tank 110. The outlet of the first water pump 140 is connected to the top of the mixing tank 110 via a pipe. The first water pump 140 is used to pump water from the water source into the mixing tank 110 to dissolve the solid fertilizer and form a mixed liquid. The bottom of the mixing tank 110 is connected to the inlet of the second water pump 150. There are two buffer tanks 130. The outlet of the second water pump 150 is connected to a diversion pipe 151. The diversion pipe 151 is connected to the top of the two buffer tanks 130 respectively via two first solenoid valves 152. The fertilizer and liquid water that have been mixed inside the mixing tank 110 will form a mixed liquid. The mixed liquid can be alternately pumped to the two buffer tanks 130 by the second water pump 150. During the transportation process, the flow direction of the mixed liquid is controlled by controlling the opening and closing of the two first solenoid valves 152. A third water pump 160 is installed on one side of the buffer tank 130. The inlet of the third water pump 160 is connected to a mixing pipe 161. The mixing pipe 161 is connected to a first water inlet pipe 163 and a second water inlet pipe 164 via a three-way diverter valve 162. The two buffer tanks 130 are connected to the first water inlet pipe 163 via second solenoid valves 165. The first water pipe is used to receive the mixed liquid from inside the buffer tank 130, and the second water pipe is used to draw irrigation water from the water source. The liquids in the first and second water pipes will be mixed in the mixing pipe 161. Because the fertilizer concentration in the mixed solution is high, after the above mixing, the final fertilizer concentration in the liquid in the mixing pipe 161 will meet the usage requirements. Here, the three-way diverter valve 162 can be an electric / pneumatic three-way regulating valve or a manual three-way diverter valve. The three-way diverter valve 162 can adjust the ratio of water entering the mixing pipe 161 from the first water inlet pipe 163 and the second water inlet pipe 164, thereby adjusting the final fertilizer concentration in the liquid in the mixing pipe 161, so that its concentration reaches the optimal ratio.The above-mentioned water inlet ratio should be flexibly adjusted according to the fertilizer input ratio at the mixing tank 110. The water inlet ratio can be adjusted according to the specific electric / pneumatic three-way regulating valve or manual three-way diverting valve used, following the corresponding operating method. The outlet end of the third water pump 160 is connected to the irrigation water pipe 166, which is used to extend to open or culverts, or can be connected to drip irrigation tape. After mixing at the mixing tank 110, the proportion of liquid fertilizer in the mixing tank 110 will reach the usage requirements. At this time, it can be transported to the planting area for irrigation by the third water pump 160. The second water inlet pipe 164 and the water inlet end of the first water pump 140 are both extended to the water source to draw water. The water source here can be a well, the Yellow River diversion canal, etc.
[0021] In this embodiment, the working process is as follows: after the equipment is installed in the irrigation area, the second water inlet pipe 164 and the first water pump 140 are connected to the water source, and the outlet of the first water pump 140 is connected to the corresponding irrigation area. After the first water pump 140 draws enough water into the mixing tank 110, the operator puts fertilizer into the mixing tank 110 for stirring. After stirring, the mixture is alternately transported to two buffer tanks 130 for storage by the second water pump 150. When one buffer tank 130 receives the mixture from the mixing tank 110, the other buffer tank 130 is connected to the first water inlet pipe 163 through the second solenoid valve 165 and supplies water to the first water inlet pipe 163. The third water pump 160 draws the mixture and irrigation water through the first water inlet pipe 163 and the second water inlet pipe 164 respectively, and mixes them after adjusting the water ratio through the three-way diversion valve 162. Then, the mixture flows out from the irrigation water pipe 166 to the irrigation area for irrigation.
[0022] As can be seen from the above, in this embodiment, by setting up components such as the mixing tank 110, buffer tank 130, first water pump 140, second water pump 150, and third water pump 160, irrigation water can be introduced into the mixing tank 110 for mixing to form a mixed liquid. Then, the water inlet ratio of the first water inlet pipe 163 and the second water inlet pipe 164 is controlled by the three-way diversion valve 162, so that the fertilizer concentration in the irrigation water pumped out by the third water pump 160 is controllable and within a reasonable range. The two buffer tanks 130 are used alternately; one receives the liquid from the mixing tank 110 while the other supplies water to the third water pump 160. This ensures continuous use of the equipment and allows for continuous irrigation. Even when the mixed liquid in the mixing tank 110 is exhausted, some mixed liquid remains in the buffer tank 130, allowing the equipment to continue operating when the mixing tank 110 is refilled. This equipment is compact, easy to move, and can meet the needs of small-area sunflower planting areas.
[0023] In some embodiments, a high-point liquid level sensor and a low-point liquid level sensor are respectively arranged inside the buffer tank 130 from top to bottom. The high-point liquid level sensor, the low-point liquid level sensor, and the first solenoid valve 152 are all electrically connected to the PLC control box 120. In this embodiment, with the above arrangement, when the liquid level inside the buffer tank 130 reaches the high-potential liquid level sensor, the high-potential liquid level sensor sends an electrical signal to the PLC control box 120. The PLC control box 120 further controls the first solenoid valve 152 at the buffer tank 130 to close and the switch of the first solenoid valve 152 connected to the other buffer tank 130 to open, so that the mixed liquid in the mixing tank 110 enters the other buffer tank 130. As one of the mixing tanks 110 supplies water to the third water pump 160, when its internal liquid level drops to the low-point liquid level sensor, the low-point liquid level sensor sends an electrical signal to the PLC control box 120. At this time, the corresponding valve can be opened to supply water to the buffer tank 130.
[0024] In some embodiments, a glass tube level gauge 131 is connected to one side of the buffer tank 130. In this embodiment, the remaining liquid level in the buffer tank 130 can be observed intuitively and conveniently by setting the glass tube level gauge 131.
[0025] In some embodiments, the top of the buffer tank 130 is connected to a pressure stabilizing pipe 132, and the other end of the pressure stabilizing pipe 132 is connected to the top of the mixing tank 110. In this embodiment, with the above configuration, when the third water pump 160 draws liquid from the buffer tank 130, the air inside the mixing tank 110 will enter the pressure stabilizing pipe 132, thereby ensuring the stability of the air pressure inside the buffer tank 130. Furthermore, when the equipment malfunctions and the high-potential liquid level sensor and the low-point liquid level sensor fail, when the second water pump 150 continuously pumps the mixture to one of the buffer tanks 130, the liquid inside the buffer tank 130 will overflow into the mixing tank 110 through the pressure stabilizing pipe 132 after it is full, thus providing a certain overflow prevention function.
[0026] In some embodiments, a base 170, a mixing tank 110, a buffer tank 130, and a PLC control box 120 are all mounted on the base 170. A strip-shaped mounting plate 171 is provided on the top of the base 170, and threaded holes are provided at the mounting plate 171. The buffer tank 130 is connected to the mounting plate 171 by screws. In this embodiment, the base 170 facilitates the overall handling of the equipment. The base 170 can be welded from a steel frame or made of wood.
[0027] In some embodiments, the bottom of the base 170 is hinged with a plurality of support feet 172 for supporting the device on the ground. In this embodiment, the support feet 172 facilitate the overall installation of the device.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although the foregoing embodiments have provided a detailed description of this application, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
