[0002] Agricultural fertilization equipment is a tool used to apply fertilizer to crop growing areas. A backpack sprayer is a type of agricultural fertilization equipment. It mainly consists of a medicine box, a pressure pump, a nozzle, etc. By manually pumping air to create a certain pressure in the medicine box, liquid fertilizer is sprayed out through the nozzle in atomized form.

[0003] In small vegetable plantations, farmers can load prepared liquid fertilizer into the medicine box of a backpack sprayer and adjust the nozzle to spray the fertilizer evenly on the soil around the vegetable leaves and roots. This is suitable for small planting areas.

[0004] When mixing ingredients and chemicals, the medicine box is usually shaken by hand. For some ingredients and chemicals with large density differences, manual shaking is difficult to overcome the stratification phenomenon. When shaking stops, the heavier ingredients will quickly sink to the bottom of the medicine box, while the lighter chemical components may float on the top. When shaking the medicine box again to prepare for the next spraying, the heavier ingredients settled at the bottom may be stirred up, forming larger particles or lumps. These lumps may flow with the liquid to the nozzle, and due to their large size, they are easy to clog the nozzle;

[0005] Therefore, in view of the above problems, a fertilizing device for agricultural planting is proposed. Utility Model Content

The sight glass 432 is convenient for observing the filtration condition and impurity accumulation in the filter tube 431, conveniently and timely backwashing operation, and extending the service life of the filter device 43;

[0029] As a further implementation scheme of the above technical solution: two stirring devices 3 are provided, and the stirring devices 3 are symmetrically arranged with the center line of the bottom of the medicine box 1 as the axis. The stirring devices 3 are respectively arranged in the middle position of both sides of the medicine box 1, and the stirring devices 3 are parallel to each other. Such an arrangement can effectively mix and stir the fertilizer solution.

[0030] As a further implementation scheme of the above technical solution: a filter tube 431 is provided between the solenoid valve 41 and the medicine box 1, with both ends of the filter tube 431 connected to the solenoid valve 41 and the two sides of the medicine box 1 respectively, and the filter tube 431 is provided at the bottom of the medicine box 1, and the filter tube 431 is perpendicular to one side of the medicine box 1. Such an arrangement facilitates filtering of large particles of fertilizer and effectively prevents the spray head 6 from being blocked;

[0031] As a further implementation scheme of the above technical solution: two connecting plates 33 are provided, and the two connecting plates 33 are symmetrically arranged. The inner side of the connecting plate 33 is hollow, and one side of the connecting plate 33 is curved.

The air pumps 31 pass through the inside of the medicine box 1 through the pipe 32 and are fixedly connected to the connecting plate 33. The air pumps 31, the pipe 32 and the connecting plate 33 correspond to each other. The air pumps 31 can effectively provide power and enhance the stirring effect.

[0033] As a further implementation scheme of the above technical scheme: a plurality of nozzles 34 and air nozzles 35 are provided, and the nozzles 34 and air nozzles 35 are evenly and equidistantly provided at both ends of the connecting plate 33.

The vertical cross-section of the air nozzle 35 is trapezoidal. The provided nozzles 34 and air nozzles 35 can generate multiple stirring points in the medicine box 1, so that the fertilizer solution rolls up and down and circulates, further improving the stirring effect.

[0034] Working process: First, put the fertilizer into the medicine box 1 with a pressure pump with its own power supply, then cover the sealing cover 2 with a screw connection to ensure that the medicine box 1 is sealed, and the stirring device 3 with its own power supply is started by pressing the button. At this time, the air pump 31 starts to work and transports the gas to the connecting plate 33 through the pipe 32. Since the inside of the connecting plate 33 is hollow, after the gas enters the connecting plate 33, it will be ejected through the nozzles 34 and air nozzles 35 evenly and equidistantly arranged at both ends of the connecting plate 33. The vertical cross-section of the air nozzle 35 is trapezoidal. The ejected gas produces a stirring effect in the medicine box 1, so that the fertilizer solution is fully mixed. The two air pumps 31 respectively spray into the medicine box 1 from the middle position on both sides of the medicine box 1, and the two stirring devices 3 are parallel to each other, which can fully stir the fertilizer solution in the medicine box 1 to prevent fertilizer precipitation. When the fertilizer solution is evenly stirred, the pressure pump is started to transport the fertilizer solution in the medicine box 1 to the nozzle 5 through the backwash device 4. The fertilizer solution first enters the filter device 43, and is filtered through the coarse filter 433 and the fine filter 434 in turn to remove For large-particle fertilizers, the visual glass 432 can be used to conveniently observe the filtering situation in the filter tube 431. The filtered fertilizer solution enters the nozzle 5 through the electromagnetic valve 41 and the connecting pipe 42, and is finally sprayed out from the spray head 6 for fertilization. When observing the coarse filter 433 and the fine filter 434 through the visual glass 432, if it is found that the coarse filter 433 and the fine filter 434 of the filter device 43 are blocked, the backwash device 4 is started, and the electromagnetic valve 41 set will switch the valve direction so that part of the nozzle 5 is blocked. The liquid flows back into the filter device 43 and the inside of the medicine box 1, and reversely flushes the coarse filter 433 and the fine filter 434 to wash away the large particles of fertilizer attached to the filter screen, thereby ensuring the normal operation of the filter device 43. After flowing into the inside of the filter device 43, the stirring device 3 provided will use the air pump 31 and the air nozzle 35 to make the fertilizer solution in the medicine box 1 roll up and down and circulate, so that the fertilizer solution is more fully mixed, thereby preventing undissolved fertilizer from blocking the filter device 43 and affecting the fertilization efficiency.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
