Description

Technical Field

[0001] The utility model belongs to the technical field of water-saving irrigation, and in particular relates to a water-saving irrigation device which is convenient for mixing fertilizers. Background Art

[0002] In traditional irrigation systems, the fertilizer mixing process is often uneven. This unevenness may cause the drip port to be blocked, which in turn causes the plant to wither due to lack of water. In addition, the existing mixing method uses an active drive structure, such as a motor, which requires additional power supply and maintenance. This not only increases the complexity of the structure, but may also increase operating costs. Utility Model Content

[0004] Furthermore, two stirring tubes are provided, the two stirring tubes are connected via a shunt tube, the extension tube is connected to the shunt tube via the movable joint, and the nozzle is screwed to both ends of the stirring tube.

[0005] Furthermore, the nozzle is obliquely arranged at the end of the stirring tube, and an angle α between the nozzle and the stirring tube is 10-30 degrees.

[0010] The beneficial effects of the utility model are as follows: the device utilizes the power of liquid flow to drive the stirring tube to rotate, which not only improves the mixing efficiency but also achieves the purpose of energy saving. The stirring tube forms a vortex in the mixing chamber, which accelerates the dissolution process of the fertilizer and ensures the uniformity of the mixing. The nozzle is set at an angle, which effectively avoids the impact of the liquid to produce bubbles and improves the mixing effect. The water pump pressurizes the liquid and sprays it through the nozzle to hit the inner wall of the mixing chamber, so that the mixture is broken up and the dissolution of the fertilizer in the liquid is accelerated, thereby achieving the dual goals of efficient mixing and water-saving irrigation. In addition, the stirring tube and the extension tube are arranged vertically relative to each other, which enhances the stability of the stirring tube when it rotates; the ratchet pawl assembly ensures that the impeller can rotate stably in one direction when the liquid flows, preventing reversal or accidental stop; the design of the movable joint and the diverter tube makes the device structure flexible and can be adjusted according to different mixing needs.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5The utility model provides the following technical solutions: a water-saving irrigation device for mixing fertilizers, comprising a mixing bin 1, a water inlet pipe 2, a water outlet pipe 3, a water pump 4, and a fertilizer bin 5. The mixing bin 1 is provided with a water inlet 6 and a water outlet 7 at the upper and lower ends. The fertilizer bin 5 is provided with a fertilizer cavity 8 for loading fertilizers. The mixing bin 1 is connected to the water pump 4 through a passive mixing component. The passive mixing component comprises an extension pipe 9, a stirring pipe 10, a nozzle 11, and an impeller 12. One end of the extension pipe 9 is connected to the water inlet 6. The extension pipe 9 is connected to the water inlet 6. The extension tube 9 is connected to the stirring tube 10 through a movable joint 13, and a plurality of nozzles 11 are symmetrically arranged on the stirring tube 10 about the origin of the extension tube 9. The mouth of the nozzle 11 is arranged facing the inner wall of the mixing bin 1. The fertilizer bin 5 is provided with a mixing channel 14 connected to the fertilizer cavity 8. The impeller 12 is installed in the fertilizer bin 5, and the impeller 12 is located between the mixing channel 14 and the fertilizer cavity 8. The two ends of the mixing channel 14 are respectively connected to the water inlet 6 and the water pump 4.

[0019] In the above structure, the water pump 4 is used to pressurize and transport the liquid, and the liquid drives the impeller 12 to rotate. While the impeller 12 rotates, the fertilizer in the fertilizer cavity 8 is pushed into the mixing channel 14 by the impeller 12. At this time, the fertilizer is not fully mixed with the liquid (hereinafter referred to as the solid-liquid mixture). The solid-liquid mixture enters the mixing bin along the extension pipe 9 and the stirring pipe 10 along with the flow of the liquid, and is finally ejected from the nozzle 11 and hits the inner wall of the mixing bin 1, so that the solid-liquid mixture is broken up. At this time, the solid-liquid mixture is ejected from the nozzle 11. Under the action of this force, the stirring pipe 10 rotates with the extension pipe 9 as the axis, and the stirring pipe 10 rotates, thereby accelerating the dissolution of the undissolved fertilizer in the liquid, and finally flows out along the outlet pipe 3.

[0020] In this embodiment, two stirring tubes 10 are provided, the two stirring tubes 10 are connected to each other through a shunt tube 15, the extension tube 9 is connected to the shunt tube 15 through the movable joint 13, and the nozzle 11 is screwed to both ends of the stirring tube 10; the stirring tube 10 and the extension tube 9 are arranged vertically relative to each other, the lengths of the two stirring tubes 10 are not equal, and the longer stirring tube 10 is arranged close to the water inlet 6.

[0021] With the above structure, the design of two stirring tubes 10 of unequal lengths helps to form a vortex in the mixing chamber 1, thereby accelerating the dissolution of the fertilizer in the liquid. The longer stirring tube 10 is arranged close to the water inlet 6. This design can ensure that the liquid and fertilizer begin to mix at an early stage when entering the mixing chamber 1, which helps to improve the mixing efficiency; the stirring tube 10 is arranged relatively vertically to the extension tube 9, which helps to ensure the stability of the stirring tube 10 when rotating.

[0022] In this embodiment, the nozzle 11 is obliquely disposed at the end of the stirring tube 10, and the angle α between the nozzle 11 and the stirring tube 10 is 10-30 degrees.

[0023] By adopting the above structure, the mixture is sprayed upward to avoid the impact of the liquid to generate bubbles, and secondly, the mixture can be better dispersed.

[0024] In this embodiment, a ratchet pawl assembly 16 is provided on the outer wall of the fertilizer bin 5 , and the ratchet pawl assembly 16 is connected to the core shaft of the impeller 12 .

[0025] The above structure is used to ensure that the impeller 12 can rotate stably when the liquid flows and can only rotate in one direction, thereby preventing the impeller 12 from reversing or stopping unexpectedly when it is not needed.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
