Description

Technical Field

[0001] The utility model relates to the technical field of water and fertilizer supply, in particular to a water and fertilizer supply device. Background Art

[0002] Water and fertilizer supply is a crucial technology in agricultural production. It involves the combination of irrigation and fertilization. An appropriate amount of fertilizer is added during the irrigation process and applied to the roots of crops through the irrigation system, which meets the needs of crops for water and nutrients, so as to promote the healthy growth of crops and improve yield and quality. Traditional fertilization methods often rely on personal experience, which is prone to too much or too little fertilizer. Too much fertilizer will cause waste and pollute the soil and environment, while too little fertilizer will not meet the growth needs of crops. Water and fertilizer supply realizes the precise supply of fertilizer for crops, reduces the waste of fertilizer and water, and can customize the amount of fertilizer according to the type and growth stage of crops.

[0023] Example

[0024] like Figure 1-2 As shown, a water-fertilizer supply device comprises a water-fertilizer tank 1, wherein the water-fertilizer tank 1 is fixedly mounted on a support frame 2, an inverted conical partition 5 is arranged in the water-fertilizer tank 1, and the partition 5 divides the inner cavity of the water-fertilizer tank 1 into an upper fertilizer cavity and a lower water-fertilizer cavity, a metering bin 6 is arranged at the bottom of the partition 5, a lower material bin 12 is arranged at the bottom of the metering bin 6, a water inlet 3 is arranged on the rear wall of the water-fertilizer cavity, a water level meter 4 is arranged on the inner side wall of the water-fertilizer cavity, a stirring device is arranged in the water-fertilizer cavity, and a liquid outlet pipe 18 is arranged at the bottom of the water-fertilizer tank 1.

[0025] It is worth noting that the water-fertilizer box 1 is provided to store water-soluble powdered fertilizers and to mix water and fertilizers. The fertilizer chamber in the water-fertilizer box 1 is used to store powdered fertilizers, and the water-fertilizer chamber is used to mix water and fertilizers. The metering bin 6 meters the powdered fertilizers, and the amount of fertilizers entering the feed bin 12 from the metering bin 6 is within the error range. The feed bin 12 breaks up the clumped fertilizers and adds them to the water-fertilizer chamber. Water is added to the water-fertilizer chamber through an external water pipe connected to the water inlet 3 to mix water and fertilizers. The water level meter 4 monitors the water level in the water-fertilizer chamber. The stirring device mixes the water and fertilizers evenly and prevents the water and fertilizers from precipitating. The liquid outlet pipe 18 is connected to an external irrigation device to fertilize the crops.

[0026] In some feasible embodiments, valves are provided at the water inlet 3 and the water outlet of the liquid outlet pipe 18 .

[0027] When the water level meter 4 detects that there is no liquid in the water fertilizer chamber, the valve at the water inlet 3 is controlled to open to add water, until the water level in the water fertilizer chamber reaches the preset water level, the valve at the water inlet 3 is controlled to close and stop adding water. The valve at the liquid outlet pipe 18 is used to control the amount of water fertilizer applied.

[0028] The water level meter 4 controls the water inlet into the water-fertilizer chamber to reach a specified amount, and the specified amount of fertilizer is discharged through the metering bin 6, so that there is no need for manual proportioning, and the proportioning work is completed by the equipment.

[0029] In some feasible embodiments, the metering bin 6 includes a bin cover 7 at the top, a bin bottom 8 at the bottom, and a metering assembly. Both the bin cover 7 and the bin bottom 8 are provided with a fan-shaped notch with a central angle of 90°. The included angle between the fan-shaped notch of the bin cover 7 and the bin bottom 8 is 90°. When the bin cover 7 rotates 180°, the projection of its fan-shaped notch coincides with the fan-shaped notch of the bin bottom 8. The metering assembly includes two spacers 9, a first rotating shaft 10, and a first motor 11. The spacer 9 is a fan-shaped cylinder with a central angle of 90°. The two spacers 9 are rotatably arranged in the metering bin 6 through the first rotating shaft 10. The two spacers 9 are axially fixed on the outer surface of the first rotating shaft 10. The included angle between the two spacers 9 is 90°. The first motor 11 is fixedly arranged on the top of the water-fertilizer tank 1, and the output end of the first motor 11 is fixedly connected to the top of the first rotating shaft 10.

[0030] Particularly, the bottom of the bin bottom 8 is connected to the top opening of the lower bin 12 through a fan-shaped notch.

[0031] Specifically, the first rotating shaft 10 is rotatably connected to the bin cover 7 and the bin bottom 8. The first motor 11 drives the first rotating shaft 10 to rotate, driving the two spacers 9 to rotate between the bin cover 7 and the bin bottom 8. The two spacers 9 separate the metering bin 6 into two equal-sized spaces a and b. The cross-sectional sizes of the two spaces are equal to the fan-shaped notches on the bin cover 7 and the bin bottom 8. When space a is located below the fan-shaped notch of the bin cover 7 and space b is located above the fan-shaped notch of the bin bottom 8, space a is filled with fertilizer. At this time, after the first motor 11 is controlled to drive the first rotating shaft to rotate 180°, space a is located above the fan-shaped notch of the bin bottom 8, and space b is located below the fan-shaped notch of the bin cover 7. At this time, the fertilizer in space a falls into the lower feeding bin 12 below, and space b begins to be filled with fertilizer. When fertilizer needs to be added next time, the first motor 11 is controlled to drive the first rotating shaft 10 to rotate 180°, then the fertilizer in space b falls into the lower feeding bin 12, and space a begins to be filled with fertilizer, and the cycle is repeated.

[0032] In some feasible embodiments, the stirring device includes a second rotating shaft 15, a second rotating plate 16 and a second motor 17. The second rotating plate 16 is fixedly arranged on the outer surface of the second rotating shaft 15 along the axial direction. The second motor 17 is fixedly arranged at the bottom of the water-fertilizer tank 1, and the output end of the second motor 17 is fixedly connected to the bottom end of the second rotating shaft 15. The second motor 17 drives the second rotating shaft 15 to rotate, and the second rotating shaft 15 drives the second rotating plate 16 to rotate to stir the liquid in the water-fertilizer chamber.

[0033] In some feasible embodiments, a filter plate 14 is provided at the bottom of the lower bin 12, the top of the second rotating shaft 15 is located in the lower bin 12, the second rotating shaft 15 is rotatably connected to the filter plate 14, and a first rotating plate 13 is fixedly provided along the axial direction on the outer surface of the portion of the second rotating shaft 15 located in the lower bin 12. The rotation of the second rotating shaft 15 drives the first rotating plate 13 to rotate, and the rotation of the first rotating plate 13 stirs the fertilizer in the lower bin 12 to break up the agglomerated fertilizer, and the rotation of the first rotating plate 13 can assist the fertilizer to enter the water-fertilizer chamber through the filter plate 14.

[0034] When in use, first add fertilizer to the water-fertilizer box 1, add water to the water-fertilizer box 1 through the water inlet 3, control the first motor 11 to drive the first rotating shaft 10 to rotate 180° to add fertilizer to the lower silo 12, start the second motor 17, and the first rotating plate 13 rotates to assist the lower silo 12 to add fertilizer to the water-fertilizer chamber. The second rotating plate 16 rotates to mix the water and fertilizer evenly. When fertilization is needed, open the valve at the liquid outlet pipe 18, and the water and fertilizer enter the external irrigation device to irrigate the crops.
