Two ventilation straight pipes 18 are fixedly inserted into the surface of the push support sleeve 17. The top of the inner cavity of the push support sleeve 17 is fixedly connected with an inner push pipe 19.A sealing piston push plate 20 is fixedly connected to the bottom of the inner push tube 19. The surface of the sealing piston push plate 20 is in extrusion contact with the inner wall of the rectangular pressurizing tube 16. An insert 21 is fixedly connected to the bottom of the sealing piston push plate 20. Through the arrangement of the insert 21, when the insert 21 moves downward, it can downwardly support the two closing plates 23, opening the closure of the closing plates 23, so that the gas in the lower part of the sealing piston push plate 20 can be back-pressed through the notch of the insert 21 into the back box 1, and the air flow in the lower part of the rectangular pressurizing tube 16 is unobstructed. A partition plate 22 is sleeved on the surface of the insert 21, and the outer surface of the partition plate 22 is fixedly connected to the inner wall of the rectangular pressurizing tube 16.

A pressurizing grip push handle 25 is fixedly connected to the top of the right side of the push support sleeve 17. An anti-slip soft sleeve is sleeved on the surface of the pressurizing grip push handle 25. Through the arrangement of the pressurizing grip push handle 25, it plays an effect of facilitating the up and down displacement of the push support sleeve 17. An internal thread turntable 26 is fixedly connected to the top of the outer sleeve straight support tube 10. A plurality of rotating grips are fixedly connected to the annular outer surface of the internal thread turntable 26. A push-pull handle 27 is fixedly connected to the top of the threaded push-rotating rod 9. A side storage bin 28 is fixedly connected to the left side of the back box 1. The inside of the side storage bin 28 is communicated with the inside of the back box 1. A sealing cap 29 is threadedly sleeved on the pipe orifice at the top of the side storage bin 28. Through the arrangement of the side storage bin 28, it plays an effect of being able to pour fertilizers into the inside of the back box 1 through the side storage bin 28 according to the usage requirements.,

[0025] During use, before using, first remove its telescopic bellows 5 from the annular snap ring 7, adjust the length, rotate and remove the closed sleeve head 6, then insert the end of its telescopic bellows 5 into the manure and urine tank and the liquid biogas pond, and then pull up the push-pull handle 27 upward, so as to pull up the threaded push-rotating rod 9 and the outer sleeve straight support cylinder 10 upward, so that the rectangular piston push plate 12 and the sealing abutting plate 11 are displaced upward synchronously. And the rectangular piston push plate 12 is displaced upward inside the rectangular air chamber cylinder 8, making the air pressure inside the back box 1 smaller until the top of the sealing abutting plate 11 is squeezed and closed with the bottom of the rectangular air chamber cylinder 8. At this time, the manure, urine or liquid biogas is sucked into the inside of the back box 1 until the air pressure inside the back box 1 is stable. When it is necessary to continuously suck the manure, urine or liquid biogas, the closed cover cylinder 14 can be rotated again. By opening the sealing cone cylinder 15 to block the ventilation cross tube 13, the inside of the rectangular air chamber cylinder 8 is communicated with the external air. Secondly, rotate the internal thread turntable 26 again. Using the thread propulsion principle of the internal thread turntable 26 and the threaded push-rotating rod 9, drive the rectangular piston push plate 12 to displace inside the rectangular air chamber cylinder 8, compress the gas inside the rectangular air chamber cylinder 8 outward. Then the closed cover cylinder 14 can be threadedly connected to the ventilation cross tube 13, and the internal thread turntable 26 is rotated in the reverse direction to adjust the rectangular piston push plate 12 to the upper space inside the rectangular air chamber cylinder 8. Then push down the push-pull handle 27 downward, so that the sealing abutting plate 11 is separated from the bottom of the rectangular air chamber cylinder 8, and the air pressure inside the back box 1 decreases again immediately. At this time, the manure, urine or liquid biogas is continuously sucked into the back box 1. By circulating in this way, the manure, urine or liquid biogas can be sucked into the inside of the back box 1 through the telescopic bellows 5 according to the demand. When fertilization is needed, carry this device to the place where fertilization is needed by wearing the back strap 2. Then hold the handle on the spraying valve head 4 and open the cover in front of the spraying valve head 4, and then accurate fertilization of the farmland can be started. When it is necessary to increase the spraying range and intensity of the spraying valve head 4, the pressurizing grip push handle 25 can be pressed up and down back and forth to drive the push support sleeve 17 to displace up and down. Using the sealing piston push plate 20 to displace inside the rectangular pressurizing tube 16, cooperate with the insert 21 to push the closing plate 23, so as to inject pressure into the inside of the back box 1. Utilizing the air pressure difference, increase the spraying pressure of the spraying valve head 4, so as to easily spray the manure, urine or liquid biogas contained in the back box 1 to the accurate position through the spraying pipe 3 and the spraying valve head 4, thus greatly improving the efficiency of applying organic fertilizer in rural households. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0026] In summary, for this small organic fertilizer applicator, through the setting of the back box 1, and the combined use of the backpack strap 2, the spraying pipe 3, the spraying valve head 4, the telescopic corrugated pipe 5, the closed sleeve head 6, the rectangular air chamber cylinder 8, the threaded push-rotating rod 9, the outer sleeve straight support cylinder 10, the plugging and resisting backing plate 11, the rectangular piston push plate 12, the ventilation cross pipe 13, the closed cover cylinder 14, the plugging cone cylinder 15, the rectangular pressurizing pipe 16, the push support sleeve 17, the ventilation straight pipe 18, the inner push pipe 19, the sealing piston push plate 20, the insert 21, the partition plate 22, the closed plate 23, the return spring 24 and the internal thread turntable 26, it plays the role that by inserting the end of its telescopic corrugated pipe 5 into the manure vat and the liquid biogas pond, and then by pulling up the threaded push-rotating rod 9, making its rectangular piston push plate 12 displace upward inside the rectangular air chamber cylinder 8, reducing the air pressure inside the back box 1, the manure or liquid biogas can be sucked into the inside of the back box 1 through the telescopic corrugated pipe 5. Subsequently, by moving the push support sleeve 17 up and down, using the displacement of the sealing piston push plate 20 inside the rectangular pressurizing pipe 16, and cooperating with the insert 21 to push and support the closed plate 23, injecting pressure into the back box 1, and using the air pressure difference, the manure or liquid biogas contained inside the back box 1 is sprayed to the accurate position of the farmland through the spraying pipe 3 and the spraying valve head 4, thus greatly improving the efficiency of applying organic fertilizers in rural households and reducing the leakage of manure or liquid biogas during the loading process.
