Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation and fertilization technology, and particularly relates to a variable-diameter drip irrigation pipe for integrated water and fertilizer. Background Technique

[0002] In a drip irrigation system, from the water source to all corners of the field, the pressure varies greatly due to different distances. The area close to the water source has a greater pressure, while the area far from the water source has a smaller pressure. The variable-diameter drip irrigation pipe can adapt to this pressure change. A larger pipe diameter is adopted in the area with a large pressure to withstand a large water flow rate and pressure. The cultivation management measure of effectively combating drought and saving water and improving the water use efficiency is an economical and effective way to achieve efficient water use and reduce losses caused by drastic changes in the water environment.

[0003] The applicant found through retrieval that the Chinese patent discloses "a peanut film-covered drip irrigation and integrated water and fertilizer device", and its publication (announcement) number is "CN204539828U". This patent mainly connects a water pipe and a water bucket. The water bucket is connected to a soft main water pipe through a water pipe. A branched drip irrigation pipe is arranged on one side of the soft main water pipe. The outer wall of the drip irrigation pipe is provided with a "worker"-shaped permeation pipe. The integrated device of the utility model has the advantages of convenient operation, accuracy and reliability. This device is applicable to the integrated drip irrigation system of water, fertilizer and gas for peanut root zone irrigation, and has the advantages of water saving, high fertilizer utilization rate, yield increase, low labor cost, etc. However, in the above-mentioned prior art, the installation of the drip irrigation pipe is relatively simple, and the connection between the main water pipe and the branched drip irrigation pipe is not fixed. It is easy for the connection point to bear a large stress due to the weight of the drip irrigation pipe itself and the weight of the water and fertilizer mixture in the pipe. Under long-term action, it may cause the deformation of the pipe fittings at the connection part and lead to water leakage. Therefore, we propose a variable-diameter drip irrigation pipe for integrated water and fertilizer. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1:

[0022] Please refer to the attached Figure 1 -attached Figure 2 、attached Figure 4 -attached Figure 5 , a variable-diameter drip irrigation pipe for integrated water and fertilizer, including a fertilizer application tank 1. A main water pipe 3 is fixedly installed at the bottom right end of the fertilizer application tank 1. A plurality of branch drip irrigation pipes 5 are arranged on the circumferential surface of the main water pipe 3 at equal intervals. The branch drip irrigation pipes 5 are variable-diameter pipes. The connection with the main water pipe 3 is the largest-diameter opening. The pressure in the area close to the water source is relatively large, while the pressure in the area far from the water source is relatively small. The variable-diameter branch drip irrigation pipes 5 can adapt to this pressure change. Larger pipe diameters are used in areas with high pressure to withstand larger water flow rates and pressures; smaller pipe diameters are used in areas with low pressure, which can not only meet the irrigation requirements but also avoid the unevenness or abnormal operation of the branch drip irrigation pipes 5 due to insufficient pressure. A stabilizing device 6 is provided at the connection between the main water pipe 3 and the branch drip irrigation pipes 5. The stabilizing device 6 includes an installation ring 601. The installation ring 601 is connected to a connecting plate 604 through a left fixing ring 602 and a right fixing ring 603. The bottom of the connecting plate 604 is fixedly connected with installation anchor bolts 605. One end of the installation ring 601 is fixedly installed with two first connecting pieces 606. One end of each of the left fixing ring 602 and the right fixing ring 603 is fixedly installed with two second connecting pieces 608. The two first connecting pieces 606 and the two second connecting pieces 608 are respectively threadedly connected through a first fixing bolt 607 and a second fixing bolt 609. An installation plate 2 is fixedly installed on the right outer wall of the fertilizer application tank 1. A water pump 4 is fixedly installed at the bottom of the installation plate 2. The two ends of the main water pipe 3 are respectively fixedly installed at the input end and the output end of the water pump 4. A water inlet pipe 10 is fixedly installed at the left end of the fertilizer application tank 1. A fertilizer addition port 8 is fixedly connected to the top of the fertilizer application tank 1. The installation ring 601 is sleeved on the circumferential surface of the branch drip irrigation pipe 5. The left fixing ring 602 and the right fixing ring 603 are respectively fixedly installed at the left and right ends of the bottom of the installation ring 601. Two groups of connecting plates 604 are provided and are respectively fixedly installed on the front and back sides between the left fixing ring 602 and the right fixing ring 603. Two groups of installation anchor bolts 605 are provided and are symmetrically arranged.

[0023] The drip head 9 usually has a special flow channel structure inside, such as a labyrinth flow channel or a long and thin pipe structure. These structures can generate a large resistance to the water flow, so that the water can only flow out drop by drop from the water outlet of the drip head 9 at a very slow speed, thus realizing accurate water volume control. Rubber pads are provided on the inner walls of the mounting ring 601, the left fixing ring 602 and the right fixing ring 603 to prevent damage to the branch drip irrigation pipe 5 and the main water pipe 3 caused by over-tight clamping. The first fixing bolt 607 and the second fixing bolt 609 are used for locking, which is convenient for installation and disassembly, and the installation is also stable.

[0024] Specifically, before laying the main water pipe 3 and the branch drip irrigation pipe 5 in the field, first, the mounting ring 601, the left fixing ring 602 and the right fixing ring 603 are respectively sleeved on the circumferential surfaces of the branch drip irrigation pipe 5 and the main water pipe 3, and then tightened by the first fixing bolt 607 and the second fixing bolt 609. Subsequently, the mounting anchor pins 605 on both sides are driven into the soil with the help of external tools to complete the fixation, preventing the position of the main water pipe 3 from moving during the fertilization process, and at the same time protecting the connection part of the main water pipe 3 and the branch drip irrigation pipe 5 to prevent the pipe fittings at the connection part from deforming due to the influence of external forces.

[0025] Embodiment 2:

[0026] Please refer to the appendix Figure 1 -appendix Figure 3 and, on the basis of Embodiment 1, it is further obtained that drip heads 9 are fixedly installed at one ends of multiple branch drip irrigation pipes 5 far away from the main water pipe 3. Three support columns 11 distributed in a circumferential array are fixedly installed at the bottom of the fertilizer tank 1. A stirring device 7 is arranged inside the fertilizer tank 1. The stirring device 7 includes a rotating motor 701. The output end of the rotating motor 701 penetrates through the top of the fertilizer tank 1 and is fixedly connected to a rotating shaft 702. Upper fixing plates 703 and lower fixing plates 704 are respectively fixedly connected to the circumferential surfaces of the upper and lower ends of the rotating shaft 702. Connecting shafts 705 are fixedly connected between the two sides of the upper fixing plate 703 and the lower fixing plate 704. Spiral stirring blades 706 are fixedly connected to the circumferential surfaces of the two connecting shafts 705. Scrapers 707 are fixedly connected to the circumferential surfaces of both sides at the bottom end of the rotating shaft 702. The rotating motor 701 is fixedly connected to the center of the top of the fertilizer tank 1. The bottom of the scraper 707 is in contact with the inner bottom surface of the fertilizer tank 1.

[0027] Some fertilizers, such as some compound fertilizers or organic fertilizers, have relatively poor solubility. For example, some components of compound fertilizers containing a large amount of trace elements may not be easily soluble in water. If not stirred, the fertilizer may settle at the bottom of the fertilization tank 1, resulting in uneven fertilization and affecting the crop's absorption of the fertilizer. The stirring device 7 can make the fertilizer particles fully contact with water, accelerate the dissolution process of the fertilizer, and ensure that the concentration of the fertilizer solution is uniform. The directions of the drippers 9 on the top of the multiple branch drip irrigation pipes 5 are alternately distributed, which is convenient for fertilization over a larger range. The two spiral stirring blades 706 are set in opposite directions to make the stirring more sufficient.

[0028] Specifically, fertilizer is added into the fertilizing tank 1 through the fertilizer adding port 8. When water enters the fertilizing tank 1 through the water inlet pipe 10, the rotating motor 701 is turned on to drive the rotating shaft 702 to rotate. At the same time, the connecting shaft 705 and the spiral stirring blade 706 are driven to rotate through the upper fixed plate 703 and the lower fixed plate 704 to fully mix the fertilizer and water. The scraper 707 at the bottom scrapes up the precipitated fertilizer and mixes it with water. It is difficult to evenly disperse the fertilizer in the water by natural diffusion alone. The stirring device 7 can effectively mix the high-concentration fertilizer with the water, thereby avoiding the possibility that some components in the fertilizer may not be completely dissolved in the water.

[0029] Working principle of the utility model: The utility model is a variable diameter drip irrigation pipe for water and fertilizer integration. First of all, fertilizer is added into the inside of the fertilizer tank 1 through the fertilizer adding port 8. When the water source enters the fertilizer tank 1 through the water inlet pipe 10, the rotating motor 701 is turned on to drive the rotating shaft 702 to rotate. At the same time, the connecting shaft 705 and the spiral stirring blade 706 are driven to rotate through the upper fixed plate 703 and the lower fixed plate 704 to fully mix the fertilizer and water. The scraper 707 at the bottom scrapes up the precipitated fertilizer and mixes it with water. After the fertilizer and water are fully mixed, the main water pipe 3 and the branch drip irrigation pipe 5 are laid in the field. Before that, the installation ring 601, the left fixing ring 602 and the right fixing ring 603 are respectively sleeved on the circumferential surfaces of the branch drip irrigation pipe 5 and the main water pipe 3, and then they are tightened by the first fixing bolt 607 and the second fixing bolt 609. Then, with the help of external tools, the installation anchors 605 on both sides are driven into the ground to complete the fixation. The connection between the main water pipe 3 and the branch drip irrigation pipe 5 is protected to prevent the deformation of the pipe fittings at the connection part caused by the influence of external forces. Then, the water pump 4 is turned on to spray out through the main water pipe 3, the branch drip irrigation pipe 5 and the dripper 9 in turn to complete the fertilization process. At this point, the whole process ends.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
