DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 3 An embodiment of the present invention provides a water-fertilizer integrated machine, comprising: an outer frame 1, a water delivery pump 7, a fertilizer pump 8 and a chassis 2.

[0028] Among them, Figure 1-Figure 5 As shown, the water pump 7, the fertilizer pump 8 and the chassis 2 are respectively arranged inside the outer frame 1, and a barrel body 21 is installed inside the chassis 2. The water inlet of the water pump 7 is connected to the water inlet pipe 5, and the water outlet is connected to the top center of the barrel body 21 through the first tube body 11. The water inlet of the fertilizer pump 8 is connected to the fertilizer main pipe 6, and the water outlet is connected to the inside of the barrel body 21 through the second tube body 12. A circular screen 14 is fixedly connected to the inner wall of the barrel body 21, and an annular support plate 15 is fixedly connected to the inner wall of the barrel body 21, and the top of the annular support plate 15 is attached to the bottom of the screen 14.

[0029] The water source enters the water pump 7 through the water inlet pipe 5, and is transported to the connecting pipe 13 through the first pipe body 11, and is finally sprayed into the barrel body 21 through the water spray pipe 16. At the same time, the fertilizer enters the fertilizer pump 8 through the fertilizer main pipe 6. The fertilizer pump 8 extracts the fertilizer and transports it to the barrel body 21 through the second pipe body 12, and flows into the top of the screen 14 to mix with the water source. The screen 14 can filter the fertilizer and intercept a larger volume of fertilizer for subsequent crushing processing.

[0030] Furthermore, the end of the fertilizer main pipe 6 is connected to a plurality of fertilizer delivery branch pipes 3 , and the fertilizer delivery branch pipes 3 are installed with solenoid valves 4 , which can control the fertilizer output state of the fertilizer delivery branch pipes 3 .

[0031] It should be noted that, refer to Figure 3 The annular edge of the screen 14 is tilted upward by 20°, and the fertilizer or water source can be guided to flow toward the middle of the screen 14 by setting the tilt angle.

[0032] In this embodiment, Figure 1-Figure 6 As shown, the end of the first tube body 11 is connected with a rotating pipe joint 26, and the bottom end of the rotating pipe joint 26 is connected with a connecting pipe 13. The outer wall of the connecting pipe 13 is connected with three water spray pipes 16 distributed in a circle, and the water outlet of the water spray pipe 16 is horizontally inclined downward by 25°. The bottom end of the connecting pipe 13 is rotatably installed on the top of the screen 14, and three crushing rollers 17 are symmetrically installed on the outer wall of the bottom end of the connecting pipe 13. A driving mechanism is installed on the top of the barrel body 21, and the driving mechanism includes a motor 10. The motor 10 is installed on the top of the barrel body 21. The outer wall of the connecting pipe 13 is fixedly connected with a first gear 25, and the rotating shaft of the motor 10 is fixedly connected with a second gear 27, and the first gear 25 is meshed with the second gear 27.

[0033] After the fertilizer is mixed with water, the second gear 27 is driven by the starting motor 10 to mesh with the first gear 25, and the connecting pipe 13 and the crushing roller 17 are driven to rotate. The outer wall of the crushing roller 17 fits the top of the screen 14 and runs to further crush the fertilizer or the solid fertilizer in the mixture, ensuring the uniformity and fluidity of the mixed liquid. Among them, the water spray pipe 16 on the connecting pipe 13 can rotate to spray water, and its water outlet is tilted downward by 25° to ensure that the mixed liquid can be evenly sprayed onto the inner wall of the barrel body 21, so that the water source can not only mix with the fertilizer, but also can flush the residual fertilizer attached to the inner wall of the barrel body 21 and the edge of the screen 14, so that it flows to the center of the screen 14, reducing the fertilizer residue phenomenon and improving the cleaning effect of the inner wall of the barrel body 21.

[0034] Furthermore, a rod body 28 is fixedly connected to one end of the bottom of the connecting tube 13, and a stirring rod 22 is installed on the outer wall of the rod body 28. The stirring rod 22 is located at the bottom of the screen 14. When the connecting tube 13 rotates, it can drive the rod body 28 and the stirring rod 22 to rotate, thereby evenly stirring the fertilizer or mixture at the bottom of the barrel body 21.

[0035] In this embodiment, Figure 3 and Figure 4 As shown, the outer wall of the connecting pipe 13 and the bottom of the screen 14 are fixedly connected with an annular plate 18, and the adjacent sides of the two annular plates 18 are provided with a plurality of friction blocks 24 arranged equidistantly around the circumference, and the friction blocks 24 on the adjacent sides of the two annular plates 18 fit each other.

[0036] When the connecting pipe 13 rotates, it can drive the friction block 24 at the top of the annular plate 18 installed on the connecting pipe 13 and the friction block 24 at the bottom of the annular plate 18 installed at the bottom of the screen 14 to rub against each other, so that the screen 14 produces high-frequency vibration, accelerates the mixing of fertilizer and water source, and accelerates the fine fertilizer residue after rolling and crushing to fall into the bottom of the barrel body 21 through the screen 14, thereby improving the crushing and filtration efficiency of the fertilizer.

[0037] like Figure 3 As shown, a main control machine 9 is installed on the top of the chassis 2. The main control machine 9 is electrically connected to the electrical control ends of the solenoid valve 4, the water pump 7, the fertilizer pump 8 and the motor 10. The main control machine 9 can control the operating status of the solenoid valve 4, the water pump 7, the fertilizer pump 8 and the motor 10.

[0038] Among them, Figure 3 As shown, the inner wall of the barrel body 21 is fixedly connected with a bracket 19 , a bearing 20 is embedded in the bracket 19 , and the rod body 28 passes through the bearing 20 . The bracket 19 and the bearing 20 can support the outer wall of the rod body 28 .

[0039] Specifically, one side of the barrel body 21 is connected to a discharge pipe 23 , and the fertilizer, water source or mixture in the barrel body 21 can be discharged to the outside through the discharge pipe 23 .

[0040] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: first, water enters the water pump 7 through the water inlet pipe 5, and is transported to the connecting pipe 13 through the first pipe body 11, and finally sprayed into the barrel body 21 through the water spray pipe 16. At the same time, the fertilizer enters the fertilizer pump 8 through the fertilizer main pipe 6. The fertilizer pump 8 extracts the fertilizer and transports it to the barrel body 21 through the second pipe body 12, and flows into the top of the screen 14. After the fertilizer is mixed with water, the second gear 27 and the first gear 27 are driven by the starting motor 10. The gears 25 mesh with each other and drive the connecting pipe 13 and the crushing roller 17 to rotate, wherein the water spray pipe 16 on the connecting pipe 13 can rotate to spray water, and its water outlet is tilted downward by 25 degrees, so as to ensure that the mixed liquid can be evenly sprayed on the inner wall of the barrel 21, so that the water source can not only mix with the fertilizer, but also can flush the residual fertilizer attached to the inner wall of the barrel 21 and the edge of the screen 14, so that it flows to the center of the screen 14, reducing the residual fertilizer phenomenon and improving the cleaning effect of the inner wall of the barrel 21;

[0041] In addition, three crushing rollers 17 are installed on the connecting pipe 13. Through the drive of the motor 10, the connecting pipe 13 can drive the crushing rollers 17 to rotate. The outer wall of the crushing roller 17 fits the top of the screen 14 and runs to further crush the fertilizer or solid fertilizer in the mixture, ensuring the uniformity and fluidity of the mixed liquid. At the same time, when the connecting pipe 13 rotates, it can drive the top friction block 24 of the annular plate 18 installed on the connecting pipe 13 and the bottom friction block 24 of the annular plate 18 installed at the bottom of the screen 14 to rub against each other, so that the screen 14 produces high-frequency vibration, accelerates the mixing of fertilizer and water source, and accelerates the fine fertilizer residue after crushing to fall into the bottom of the barrel 21 through the screen 14, thereby improving the crushing and filtration efficiency of the fertilizer, promoting the contact with the microorganisms, roots and other crop roots in the soil during subsequent fertilization, improving the utilization rate of fertilizer and reducing waste.
