DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0026] See also Figure 1-Figure 4 The fertilizer dissolving tank for the drip irrigation system provided in the present application comprises a tank body 1, a feed pipe 2 is provided on the top of the tank body 1 and the feed pipe 2 is connected to the inside of the tank body 1;

[0027] A water injection pipe 3 is provided on the top plate of the tank body 1 on one side of the feed pipe 2, the water inlet of the water injection pipe 3 is connected to the water inlet pipe 8 of the irrigation system, and the water outlet of the water injection pipe 3 is connected to a first water injection pipe 31;

[0028] The fertilizer dissolving tank further comprises a fertilizer dissolving pipe 4, which is spirally arranged in the tank body 1, and the fertilizer dissolving pipe 4 is detachably connected to the tank body 1;

[0029] The upper end of the fertilizer dissolving pipe 4 is connected to the lower end of the feeding pipe 2, and the lower end of the fertilizer dissolving pipe 4 is close to the bottom of the tank body 1. The first water injection pipe 31 passes through the top plate of the tank body 1 and extends into the tank body 1, and is connected to the tube body of the fertilizer dissolving pipe 4 close to the feeding pipe 2.

[0030] In the above embodiments, the existing device for mixing fertilizer and water for irrigation is stirred manually or by using an electric unit to drive a stirring mechanism to stir, so that the fertilizer is fully dissolved in the water and mixed evenly in the water. The disadvantage of manual stirring is that it is time-consuming and labor-intensive, and using an electric unit to drive a stirring mechanism for stirring will cause high energy consumption. In addition, since an additional electric unit is required, a corresponding structure will be added to cooperate, resulting in problems such as the structure of the entire device being complicated and bulky.

[0031] The present application arranges a spiral fertilizer-dissolving tube 4 inside the tank body 1 to increase the distance traveled by the fertilizer in the fertilizer-dissolving tube 4, that is, to increase the contact time between the fertilizer and water, so that the fertilizer can be fully dissolved in the water. There is no need to additionally arrange an electric structure to drive a stirring mechanism to stir the water and fertilizer, thereby saving electric power resources, reducing energy consumption, simplifying the structure of the entire device, and reducing costs.

[0032] Specifically, after the fertilizer enters the feed pipe 2, it enters the fertilizer dissolving pipe 4 and contacts the water in the first water injection pipe 31. The water in the first water injection pipe 31 disperses the fertilizer along the fertilizer dissolving pipe 4 toward the bottom of the tank body 1. When the fertilizer contacts the water, the fertilizer begins to dissolve. The spiral fertilizer dissolving pipe 4 can increase the contact time between the fertilizer and the water, so that the fertilizer can be fully dissolved.

[0033] The position where the lower end of the first water injection pipe 31 is connected to the fertilizer dissolving pipe 4 is lower than the position where the lower end of the feed pipe 2 is connected to the fertilizer dissolving pipe 4, ensuring that the fertilizer first enters the fertilizer dissolving pipe 4 and then contacts the water, and also preventing the water in the water injection pipe 3 from flowing back into the feed pipe 2;

[0034] In addition, a drainage pipe 7 is provided at the bottom of the tank body 1 , one end of the drainage pipe penetrates the bottom plate 111 of the tank body 1 and extends into the tank body 1 , and the other end of the drainage pipe 7 is connected to the outlet pipe 9 of the irrigation system.

[0035] Furthermore, waterproof baffles 5 are provided on the inner walls of both sides of the feed pipe 2 to prevent water from overflowing into the feed pipe 2 .

[0036] In a possible implementation, the waterproof baffle 5 is arranged in an inverted eight shape, which does not affect the fertilizer from the feed pipe 2 into the fertilizer dissolving pipe 4, but can prevent most of the water from flowing back from the fertilizer dissolving pipe 4 into the feed pipe 2, thereby protecting the fertilizer in the feed pipe 2;

[0037] In addition, the waterproof baffle 5 has an inverted eight-shaped structure, and can also limit the amount of fertilizer entering the fertilizer dissolving tube 4 from the feed pipe 2, that is, the fertilizer is limited by the bottom opening of the waterproof baffle 5 with an inverted eight-shaped structure, so as to avoid a large amount of fertilizer from flowing into the fertilizer dissolving tube 4 from the feed pipe 2 at one time, resulting in insufficient dissolution of the fertilizer.

[0038] Furthermore, a plurality of agitators 6 rotatable under the impact of water flow are provided in the inner wall of the fertilizer dissolving tube 4 .

[0039] In a possible implementation, the fertilizer poured into the lower port of the feed pipe 2 and the water flowing into the lower port of the first water injection pipe 31 are merged in the fertilizer dissolving pipe 4, flow along the fertilizer dissolving pipe 4 to the bottom of the tank body 1, and gradually dissolve in the flow. By arranging a stirrer 6 that can rotate under the impact of the water flow in the inner wall of the fertilizer dissolving pipe 4, the fertilizer and the water can be stirred, so that the fertilizer is quickly and fully dissolved in the water.

[0040] In addition, under the action of water flow, some fertilizers will stick to the inner wall of the fertilizer dissolving tube 4 at the bend of the fertilizer dissolving tube 4, thereby blocking the fertilizer behind. Under the action of the agitator 6, the fertilizer can be broken up to avoid the accumulation of fertilizer inside the fertilizer dissolving tube 4.

[0041] Furthermore, the fertilizer dissolving tube 4 includes a first sub-tube 41, a second sub-tube 42 and a third sub-tube 43, and the first sub-tube 41, the second sub-tube 42 and the third sub-tube 43 are detachably connected end to end in sequence, and the diameters of the first sub-tube 41, the second sub-tube 42 and the third sub-tube 43 decrease in sequence.

[0042] In a possible implementation, the detachable connection facilitates cleaning of the inner wall of the fertilizer dissolving tube 4 and the agitator 6, and also facilitates installation of the agitator 6 and the fertilizer dissolving tube 4 together;

[0043] Wherein, the detachable connection includes but is not limited to threaded connection, socket connection, etc.;

[0044] In addition, the diameters of the first sub-tube 41, the second sub-tube 42 and the third sub-tube 43 are set to be gradually reduced, and the fertilizer that enters the second sub-tube 42 and the third sub-tube 43 from the first sub-tube 41 in sequence is limited, and the fertilizer is dissolved in layers. Specifically, after the fertilizer that enters the first sub-tube 41 from the feeding pipe 2 is dissolved in the first sub-tube 41, the remaining fertilizer enters the second sub-tube 42 in small amounts and multiple times when the diameter of the second sub-tube 42 is smaller than that of the first sub-tube 41. Since the amount that enters the second sub-tube 42 at one time is small, the fertilizer can be fully dissolved, and the undissolved fertilizer enters the third sub-tube 43 with a smaller diameter than the second sub-tube 42 from the second sub-tube 42, and the undissolved fertilizer is broken up again, and decomposed in this way to achieve full dissolution of the fertilizer in water.

[0045] Furthermore, a "7"-shaped connecting rod 10 is provided on the outer wall of the first sub-tube 41 close to the second sub-tube 42 and on the outer wall of the second sub-tube 42 close to the third sub-tube 43, and a C-shaped connecting plate 11 matching the "7"-shaped connecting rod 10 is provided on the inner wall of the tank body 1.

[0046] In a possible implementation, in order to ensure the stability of the spiral fertilizer dissolving pipe 4 during operation, the inner wall of the tank body 1 is connected to the outer side of the fertilizer dissolving pipe 4 to support the fertilizer dissolving pipe 4;

[0047] Specifically, one end of the "7"-shaped connecting rod 10 is fixedly connected to the outer side of the fertilizer dissolving tube 4, a C-shaped connecting plate 11 is provided on the inner wall of the tank body 1, and the other end of the "7"-shaped connecting rod 10 extends into the C-shaped connecting plate 11, thereby realizing the support of the fertilizer dissolving tube 4 by the tank body 1.

[0048] For further information, see Figure 2 and Figure 4 The agitator 6 includes a connecting seat 61, a connecting shaft 62 and a stirring blade 63. The outer wall of the connecting seat 61 is detachably connected to the inner wall of the fertilizer dissolving tube 4 (via threaded connection or sleeve connection), one end of the connecting shaft 62 is fixedly connected to the connecting seat 61, and the stirring blade 63 is connected to the other end of the connecting shaft 62.

[0049] In a possible implementation, the stirring blade 63 is arranged on the connecting ring 12, and the connecting ring 12 is sleeved on the connecting shaft 62. A bearing 13 is provided between the connecting ring 12 and the connecting shaft 62. When the fertilizer passes through the connecting seat 61, it passes through the gap of the connecting seat 61 and moves toward the stirring blade 63. Under the impact of the water flow, the stirring blade 63 rotates around the connecting shaft 62 to stir the fertilizer so that the fertilizer is fully dissolved.

[0050] Among them, the connecting seat 61 is arranged inside the fertilizer dissolving pipe 4 through threads or the connecting seat 61 is sleeved.

[0051] Furthermore, the number of the agitators 6 is three, and the three agitators 6 are respectively arranged at the ends of the first sub-tube 41 , the second sub-tube 42 and the third sub-tube 43 .

[0052] It should be noted that when installing and disassembling the first sub-tube 41, the second sub-tube 42 and the third sub-tube 43, the agitator 6 can be installed and disassembled at the same time, which is convenient for cleaning and storage of the agitator 6. In addition, when the fertilizer passes through the bend where the first sub-tube 41, the second sub-tube 42 and the third sub-tube 43 are connected, the water flow must carry the fertilizer through a bend to avoid accumulation of the fertilizer at the bend. The use of the agitator 6 can break up the fertilizer at the bend, which is beneficial to the dissolution of the fertilizer.

[0053] Furthermore, the water outlet of the water injection pipe 3 is connected to a second water injection pipe 32 , and the second water injection pipe 32 passes through the bottom plate 111 of the tank body 1 and extends into the tank body 1 .

[0054] In one possible implementation, the mixture of fertilizer and water gathers at the bottom of the tank body 1. Under the action of gravity, the concentration of the lower half of the mixture is higher than that of the upper half. By setting a second water pipe and spraying the water in the second water pipe toward the bottom, the mixture at the bottom can be diluted, thereby ensuring that the concentration of the mixture of fertilizer and water gathered at the bottom of the tank body 1 is consistent, avoiding the mixture in the lower half from being too high and causing damage to the roots or leaves of the plants when dripping to the roots or leaves of the plants.

[0055] The actual use process of the device of the present application is as follows: the fertilizer is poured into the fertilizer dissolving tube 4 through the feed tube 2, and the fertilizer gradually enters the fertilizer dissolving tube 4 from the bottom opening of the inverted eight-shaped structure in the feed tube 2, and water flows from the water inlet of the irrigation system into the water injection tube 3 through the upper end opening of the water injection tube 3, and then is divided into the first water injection tube 31 and the second water injection tube 32 through the port of the water injection tube 3, the water in the first water injection tube 31 first contacts the fertilizer in the first sub-tube 41, dissolves the fertilizer in the first sub-tube 41, and the fertilizer and water continue to flow along the first sub-tube 41. The first sub-tube 41 flows toward the second sub-tube 42 and the third sub-tube 43. During this process, the agitator 6 stirs the water and fertilizer so that the fertilizer is fully dissolved in the water, and at the same time stirs the mixed solution of the fertilizer and water evenly until the mixed solution of water and fertilizer flows to the bottom of the tank body 1 and converges at the bottom of the tank body 1. The water in the second water injection pipe 32 can dilute the lower half of the mixed solution at the bottom of the tank body 1 to ensure that the concentration of the mixed solution remains consistent. The mixed solution is irrigated to the plants from the drainage pipe 7 at the bottom of the tank body 1 through the outlet pipe 9 of the irrigation system.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
