The inside of the tank 101 is sucked to a first negative pressure through the first passage 601 by the negative pressure device 201, so that the liquid fertilizer is fed into the tank 101 through the second passage 602 by the first negative pressure.

The liquid level detection device 301 is used for determining that the liquid fertilizer input into the storage tank 101 reaches the application amount of the liquid fertilizer.

The first valve 701 and the second valve 702 are closed.

FIG. 5 is a schematic view showing the communication state of each component of the water and fertilizer dispensing apparatus when water is supplied into the storage tank according to an embodiment of the present disclosure;

referring to fig. 2 and 5, in step S203, the step of delivering water from a water source to the storage tank 101 through the negative pressure device 201 and mixing the water with the liquid fertilizer to form a mixture may include:

the amount of water applied for application is determined.

The first valve 601 and the third valve 703 on the third passage 603 for connecting the water supply to the tank 101 are opened.

The inside of the reservoir 101 is sucked to a second negative pressure through the first passage 601 by the negative pressure device 201, so that water is fed into the reservoir 101 through the third passage 603 by the second negative pressure.

The water supplied to the tank 101 is determined by the level detection means 301 to be the amount of water to be applied and mixed with the liquid fertilizer supplied to the tank 101 to form a mixture.

The first valve 701 and the third valve 703 are closed.

FIG. 6 is a schematic view showing the communication state of each component in the liquid manure distributing apparatus when discharging the mixture out of the storage tank according to an embodiment of the present disclosure

Referring to fig. 2 and 6, the step of discharging the mixture of liquid fertilizer and water in the tank out of the tank based on gravity in step S204 may include:

a fourth valve 704 on a fourth path 604 for connecting the outside to the reservoir 101 and a fifth valve 705 on a fifth path 605 for discharging the mixture of liquid manure and water in the reservoir 101 are opened.

The mixture in the tank 101 is transported out of the tank 101 based on the action of gravity.

In one embodiment, when the level sensing device 301 senses a level of 0 in the tank 101, a delay of 2 minutes is applied before closing the fourth valve 704 on the fourth path 604 and the fifth valve 705 on the fifth path 605.

According to an embodiment of the disclosure, the amount of liquid fertilizer in the storage tank is in the range of 0% to 100% of the total amount of the mixture.

In one embodiment, the amount of the liquid fertilizer in the total amount of the mixture can be arbitrarily adjusted according to specific needs, for example, 0%, 10%, 25%, 50%, 70%, 100%.

Fig. 7 schematically shows a schematic view of a liquid manure dispensing device with a control device according to another embodiment of the present disclosure.

According to the embodiment of the present disclosure, the device for lifting liquid fertilizer and dispensing liquid fertilizer may further include a control device 901 adapted to control the input amount of liquid fertilizer and water into the storage tank 101 and the output amount of mixture discharged out of the storage tank 101 according to the liquid level detected by the liquid level detection device 301 and the vacuum degree detected by the vacuum degree detection device 501.

According to an embodiment of the present disclosure, the control device 901 may be a PLC (Programmable Logic Controller) having a function of collecting a liquid level signal in the storage tank 101 detected by the liquid level detection device 301 and a vacuum degree signal in the storage tank 101 detected by the vacuum degree detection device 501, and controlling the opening and closing of the electromagnetic valve on each passage, thereby achieving automatic control of lifting, blending, and applying the liquid manure. The control device 901 may include specific control keys such as a setting key, an on-off key, and a fertilizing key for the ratio of water to fertilizer.

According to the embodiment of the disclosure, the control device 901 and each valve are controlled and driven by weak current, so that 220V alternating current does not participate in the water and fertilizer dispensing device with the control device 901, and the power utilization safety is ensured.

In an embodiment, the step of dispensing the water and fertilizer with the control device 901 may include a first step, a second step, a third step, and a fourth step.

The method comprises the following steps: the proportion of water and fertilizer is set to be 1:4 in the control device 901, the liquid fertilizer application volume is 100L, and a fertilizer application button is started.

Step two: the controller 901 controls and opens the first valve 701 on the first path 601 and the second valve 702 on the second path, and when the negative pressure device 201 supplies negative pressure power to the storage tank 101 through the first path 601 and determines that the negative pressure in the storage tank 101 reaches a preset value through the vacuum degree detector 501, the liquid fertilizer flows from the buried fertilizer storage tank (not shown) to the storage tank 101. When the liquid level detecting means 301 detects that the liquid level in the tank 101 reaches a preset value, the first valve 701 and the second valve 702 are controlled to be closed by the control means 901.

Step three: the control device 901 controls and opens the first valve 701 on the first path 601 and the third valve 703 on the third path 602, and when the negative pressure device 2 supplies the negative pressure power to the tank 101 through the first path 601 and the vacuum degree detection device 501 determines that the negative pressure in the tank 101 reaches the preset value, water flows from the water source to the tank 101. When the liquid level detecting means 301 detects that the liquid level in the tank 101 reaches a preset value, the control means 901 controls the first valve 701 and the third valve 702 to be closed.

Step four: the control device 901 controls and opens the fourth valve 704 on the fourth path 604 and the fifth valve 705 on the fifth path 605, the mixture of the water and the fertilizer in the tank 101 is discharged out of the tank 101 through the fifth path and used for application under the action of gravity, and after the liquid level detection device 301 detects that the page in the tank 101 is zero, the control device 901 controls the fourth valve 704 and the fifth valve 705 to close after 2 minutes.
