Description
Technical Field
[0001] This invention belongs to the field of cotton drip irrigation technology, specifically a cotton water and fertilizer integrated drip irrigation and filtration device. Background Technology
[0002] In the process of large-scale cotton cultivation, water and fertilizer management is a key factor affecting cotton yield and quality. Traditional cotton irrigation methods mostly use flood irrigation and furrow irrigation, which not only have problems such as low water resource utilization and serious waste of water and fertilizer, but also easily lead to soil compaction and nutrient loss, making it difficult to meet the precise water and nutrient needs of cotton at different growth stages. With the promotion of water-saving agricultural technologies, drip irrigation has been widely used in cotton cultivation due to its advantages of water saving, fertilizer saving and precise supply.
[0003] Irrigation water sources (such as river water and well water) in cotton-growing areas often contain impurities such as silt, weed debris, etc. These impurities can easily clog the tiny holes of drip irrigation pipes, leading to uneven drip irrigation and irrigation interruptions. Frequent disassembly and cleaning of drip irrigation pipes and filtration equipment are required, increasing the intensity of manual labor and affecting irrigation efficiency. Furthermore, traditional filtration devices lack self-cleaning functions, and the filter elements are prone to reduced filtration efficiency due to the accumulation of impurities. Long-term use will exacerbate the clogging problem. Summary of the Invention

[0020] The conversion rod is slidably connected to the vertical water storage tank and is used to drive the toothed cylinder to move. The toothed cylinder is rotatably connected to one end of the conversion rod.
[0021] The baffle is fixedly mounted on the conversion rod.
[0022] A receiving trough is provided on the inner wall of the vertical water storage tank to accommodate a baffle, and the baffle is slidably connected in the receiving trough.
[0023] A threaded rod is rotatably connected to the side plate at the top of the vertical water storage tank, and a conversion rod is threaded onto the threaded rod.
[0024] As a further preferred embodiment of this technical solution, the stirring conversion structure further includes:
[0025] The feed cylinder is installed through one side of the vertical water storage tank and is used to add fertilizer into the vertical water storage tank.
[0026] As a further preferred embodiment of this technical solution, the shape of the conversion rod is L-shaped.
[0027] As a further preferred embodiment of this technical solution, the side rods on the stirring bar are arranged in a cross configuration.
[0028] As a further preferred embodiment of this technical solution: the drip irrigation integrated module includes:

[0033] As a further preferred embodiment of this technical solution: the side branch pipe is provided in several groups, and each side branch pipe is provided with a set of water stop valves.
[0034] Compared with the prior art, the beneficial effects of the present invention are:
[0035] 1. In this invention, through the synergistic effect of the self-cleaning filtration mechanism, when external water flows through the S-shaped guide channel at the top of the vertical water storage tank, the force of the water flow drives the vortex blades to rotate, thereby driving the filter screen to rotate continuously on the support frame. The inclined scraper on the inner wall of the vertical water storage tank always adheres to the surface of the filter screen, which can scrape off the filtered debris and impurities on the filter screen in real time and quickly discharge them through the corresponding outlet. There is no need for frequent manual disassembly and cleaning of the filter screen, which not only ensures the continuity of the filtration process, but also effectively removes impurities in the water source, avoiding the clogging of the subsequent drip irrigation pipe holes from the source, and ensuring the stable operation of drip irrigation.
[0036] 2. In this invention, the stirring and switching structure can flexibly switch between filtration and stirring functions. When water and fertilizer irrigation is required, fertilizer is added into the vertical water storage tank through the feeding cylinder. Twisting the threaded rod will drive the switching rod to move, so that the toothed cylinder simultaneously meshes with the teeth of the filter screen and the stirring rod. With the power transmission of the rotating filter screen, the stirring rod rotates accordingly. Its cross-shaped side rods can fully stir the water and fertilizer in the vertical water storage tank, promote the rapid dissolution and uniform dispersion of fertilizer particles, and form a water and fertilizer mixture with uniform concentration. The uniform water and fertilizer supply allows cotton plants to absorb nutrients more fully, effectively improving the nutrient utilization rate of irrigation and cotton yield.
[0037] 3. In this invention, the drip irrigation integrated module adopts a graded water supply structure of water pump-branching pipe-multiple sets of side branch pipes. After the water pump delivers clean water or water-fertilizer mixture from the vertical water storage tank to the branching pipe, it can quickly distribute the water to several sets of side branch pipes. Each set of side branch pipes is equipped with an independent stop valve, and the side branch pipes can be flexibly connected to drip irrigation pipes. This allows for flexible expansion of the drip irrigation coverage area according to the cotton planting area, enabling simultaneous irrigation of large areas of cotton fields and improving irrigation efficiency. Furthermore, by individually controlling the stop valves, the start and stop of irrigation and the amount of water in different areas can be precisely adjusted to meet the differentiated irrigation needs of cotton at different growth stages and in different planting areas. The system is convenient to operate and highly practical. Attached Figure Description

[0062] In this embodiment, specifically: the upper end of the vertical water storage tank 2 is provided with an S-shaped flow guide channel, and the vortex blade 304 is located in the S-shaped flow guide channel.
[0063] It should be noted that the outlet 306 is located on the opposite side of the water outlet end of the S-shaped guide channel at the top of the vertical water storage tank 2.
[0064] In this embodiment, the stirring conversion structure further includes: a toothed cylinder 402, which is slidably connected to the teeth on the upper end of the stirring rod 401 to drive the stirring rod 401 to rotate, and the toothed cylinder 402 is slidably connected to the teeth on the lower end of the filter screen 301; a conversion rod 403, which is slidably connected to the vertical water storage tank 2 to drive the toothed cylinder 402 to move, and the toothed cylinder 402 is rotatably connected to one end of the conversion rod 403; a baffle 404, which is fixedly arranged on the conversion rod 403; a receiving groove 405, which is opened and arranged on the inner wall of the vertical water storage tank 2 to receive the baffle 404, and the baffle 404 is slidably connected in the receiving groove 405; and a threaded rod 406, which is rotatably connected to the side plate on the upper end of the vertical water storage tank 2, and the conversion rod 403 is threadedly connected to the threaded rod 406.
[0065] In this embodiment, the stirring and conversion structure further includes a feed cylinder 407, which is disposed through one side of the vertical water storage tank 2 for adding fertilizer into the vertical water storage tank 2.
[0066] It should also be understood that the upper end of the feed cylinder 407 is bolted with a cylinder cover, which is used to seal the feed cylinder 407 when no fertilizer is added, to prevent external debris from entering the vertical water storage tank 2.
[0067] The feed cylinder 407 is located on one side below the filter screen 301, and when water is being supplied to the vertical water storage tank 2, the water level should be controlled to be below the filter screen 301.
[0068] In this embodiment, specifically, the shape of the conversion lever 403 is L-shaped.
[0069] In this embodiment, specifically, the side rods on the stirring rod 401 are arranged in a cross configuration.
[0070] In this embodiment, specifically: the drip irrigation integrated module includes: a water pump 501, which is located on one side of the lower end of the vertical water storage tank 2, and the water inlet end of the water pump 501 is sealed and connected to the bottom of the vertical water storage tank 2; a branch pipe 502, which is sealed and fixed to the water outlet end of the water pump 501; a side branch pipe 503, which is connected to the base 1 through a vertical rod, and one end is connected to the inside of the branch pipe 502; and a stop valve 504, which is located on the side branch pipe 503.
[0071] It should be noted that one end of the side branch pipe 503 can be connected to a drip irrigation pipe for drip irrigation of cotton plants and fixed with a clamp. Multiple sets of side branch pipes 503 can be set to connect multiple sets of drip irrigation pipes according to the irrigation area of cotton plants, so as to improve irrigation efficiency.
[0072] In this embodiment, specifically: the side branch pipe 503 is provided with several sets, and each side branch pipe 503 is provided with a set of water stop valves 504.
[0073] Working principle or structural principle: When in use, first install the base 1 at the place of use with bolts, and connect it to the pumping equipment through the flange on the top of the vertical water storage tank 2;
[0074] When the pumping equipment is running, water is transported from the river to the upper end of the vertical water storage tank 2. The water flows through the guide channel at the upper end of the vertical water storage tank 2 and is filtered on the filter screen 301. Then it falls into the vertical water storage tank 2 for storage. When the water passes through the guide channel at the upper end of the vertical water storage tank 2, the force of the water drives the vortex blade 304 to rotate. The vortex blade 304 drives the drive shaft 303 to rotate on the vertical water storage tank 2. The drive shaft 303 drives the filter screen 301 to rotate on the support frame 302. By driving the filter screen 301 to rotate, the cleaning scraper 305 scrapes away the impurities filtered on the surface of the filter screen 301. The water is discharged into the vertical water storage tank 2 through the outlet 306 due to the inclined setting of the cleaning scraper 305, ensuring that the filter screen 301 continuously filters the external water source and prevents blockage of the subsequent drip irrigation pipe holes.
[0075] When drip irrigation with fertile water is needed, unscrew the bolts at the top of the feed cylinder 407 to remove the cylinder cover, and put the water-soluble fertilizer into the vertical water storage tank 2 through the feed cylinder 407. After putting it in, reset the cylinder cover with the bolts. Then, turn the threaded rod 406 on the vertical water storage tank 2. The threaded rod 406 drives the conversion rod 403 to slide upward through the threaded connection. The conversion rod 403 drives the baffle 404 to slide in the receiving groove 405. At the same time, the conversion rod 403 drives the toothed cylinder 402 to move upward. When the toothed cylinder 402 meshes with the teeth on the stirring rod 401 and the filter screen 301, the rotation of the filter screen 301 drives the toothed cylinder 402 to rotate on the conversion rod 403. The toothed cylinder 402 drives the stirring rod 401 to rotate in the vertical water storage tank 2. The rotation of the stirring rod 401 mixes the fertilizer and water in the vertical water storage tank 2 evenly, improving the irrigation effect.
[0076] Then, turn on the water pump 501. The water pump 501 delivers the water in the vertical water storage tank 2 to the branch pipe 502, and then distributes the water to several sets of side branch pipes 503 through the branch pipe 502. When the drip irrigation pipe is connected to the side branch pipe 503 by clamps, the water stop valve 504 can be opened to deliver water to the drip irrigation pipe for drip irrigation of cotton plants. In addition, by setting several sets of side branch pipes 503, water can be supplied to several sets of drip irrigation pipes simultaneously, thereby increasing the drip irrigation area of cotton.
