Description

Technical Field

[0001] This utility model belongs to the field of agricultural mechanization technology, and specifically relates to a fertilizer liquid preparation and storage tank. Background Technology

[0002] Fertilizer is the material basis for increased crop yield. The traditional method of fertilizing crops involves manually or mechanically delivering raw fertilizer (factory-produced solid fertilizer and high-concentration liquid fertilizer) to the vicinity of the crop roots. This method has many problems in the fertilization process, such as the damage to crop seedlings due to excessively high fertilizer concentration; uneven distribution of fertilizer per seedling when applying solid fertilizer, affecting the fertilization effect; and low utilization rate due to fertilizer loss from volatilization or decomposition caused by frequent exposure to air.

[0003] To address this issue, some farmers add solid fertilizer or highly concentrated liquid fertilizer to buckets of water and manually stir to dissolve and dilute it into liquid fertilizer. This method is labor-intensive, time-consuming, and inefficient. Some vendors use tanks equipped with electric mixers to dissolve and dilute solid fertilizer or highly concentrated liquid fertilizer before selling it to farmers. This method is only suitable for farmers with small farmlands. Utility Model Content

[0004] The purpose of this invention is to provide a fertilizer preparation and storage tank that can prepare high-concentration liquid fertilizer or solid agricultural raw fertilizer into a fertilizer solution suitable for farming in the field. Combined with farmland irrigation, the fertilizer can be directly supplied to the roots of crops using water power, resulting in uniform fertilization.

[0005] The present invention adopts the following technical solution: an agricultural fertilizer liquid preparation and storage tank, comprising a horizontally arranged closed tank body, the inner cavity of which is divided into two independent chambers in the left and right directions by a partition, namely a preparation and storage area and a power control area;

[0006] The preparation and storage area is used to store water and solid fertilizer or high-concentration liquid fertilizer;

[0007] A mechanical pump and control cabinet are connected within the power control area. The inlet of the mechanical pump is connected to a liquid inlet pipe, and the inlet end of the liquid inlet pipe extends through the partition into the preparation and storage area, close to the partition side. The outlet of the mechanical pump is divided into two paths: the first path is a return pipe, and the second path is a liquid outlet pipe. The outlet end of the return pipe extends into the preparation and storage area, close to the side away from the partition. The liquid outlet pipe exits the power control area and extends into the space outside the tank.

[0008] The inlet pipe is used to draw water from the preparation and storage area into the mechanical pump, and pressurize it. The pressurized water is then circulated back into the preparation and storage area through the return pipe. Under the impact of the pressurized water, the water and fertilizer in the preparation and storage area are stirred and mixed to obtain agricultural fertilizer water.

[0009] The outlet pipe is used to transport agricultural fertilizer water.

[0010] Furthermore, valves are installed on the inlet pipe, return pipe, and outlet pipe, and each valve is connected to the control cabinet.

[0011] Furthermore, a material inlet and a manual inlet are provided on the tank body, located at the top of the preparation and storage area. Both the material inlet and the manual inlet are equipped with sealing caps, and a transparent glass observation window is provided on the top of each sealing cap.

[0012] Furthermore, a liquid drain valve is connected to the bottom of the tank body, at the end of the preparation and storage area away from the partition.

[0013] The beneficial effects of this utility model are: 1. It has the function of liquid reflux stirring to dissolve and dilute solid fertilizers and high-concentration liquid fertilizers, which can significantly reduce labor intensity, while the dissolution and dilution time is short and the efficiency is high. 2. It can be installed in the field, suitable for both small and large areas of farmland for the preparation and storage of agricultural fertilizer solutions. 3. It uses reflux liquid stirring instead of mechanical stirring to dissolve and dilute solid fertilizers and high-concentration liquid fertilizers, simplifying the equipment and its usage process. 4. Its control cabinet has an automatic control mode and a remote control signal receiving function, which can cooperate with remote control to remotely control the operation of the agricultural fertilizer preparation and storage tank.

The outlet end of the return pipe 13 extends into the preparation and storage area b, and is close to the side away from the partition 6. The outlet pipe 12 exits the power control area c and extends into the space outside the tank 1.

[0031] The reflux pipe 13 is located on the transverse centerline of the preparation and storage area b to ensure that the effluent can agitate the water above and below. The outlet of the reflux pipe 13 is located near the liquid drain valve for good agitation.

[0032] Mechanical pump 9 is a centrifugal pump with a power of 30kW. The drive motor of mechanical pump 9 is a variable frequency motor, powered by AC 220V power supply. Tee 7 is made of 304 stainless steel and is DN32.

[0034] The inlet pipe 14 is used to draw water from the preparation storage area b into the mechanical pump 9, and pressurize it through the mechanical pump 9. The pressurized water is then circulated back to the preparation storage area b through the return pipe 13. Under the impact of the pressurized water, the water and fertilizer in the preparation storage area b are stirred and mixed to obtain agricultural fertilizer water.

[0035] The liquid outlet pipe 12 is used to transport agricultural fertilizer water.

[0036] A door 5 that can be opened and closed is provided on the right side plate of the power control area c of the tank body 1, so that the power control area c can be connected to or closed to the outside.

[0043] Step 2: Inject a set amount of water into the preparation and storage area b through the material inlet 2, and start the mechanical pump 9. The water in the preparation and storage area b enters the mechanical pump 9 through the inlet pipe 14, and after being pressurized by the mechanical pump 9, it flows back to the preparation and storage area b through the outlet pipe 13. Under the impact of the water flow, the water in the preparation and storage area b moves rapidly.

[0044] Step 3: Through material inlet 3, add solid fertilizer or high-concentration liquid fertilizer in batches to the water in the preparation and storage area b. The fertilizer is dispersed and dissolved under the impact of water flow.

[0045] Step 4: After the fertilizer is completely dissolved, the mechanical pump 9 is stopped by the control cabinet 10. At this time, the solution in the preparation storage area b is a prepared agricultural fertilizer solution of a certain concentration.

[0046] When applying liquid fertilizer, close the valve on the return pipe 13, open the valve on the outlet pipe 12, start the mechanical pump 9, and the liquid fertilizer can be output through the outlet pipe 12.

[0047] The above-mentioned method for preparing and storing agricultural fertilizer liquid is as follows: The agricultural fertilizer liquid is prepared by the stirring method of the above-mentioned agricultural fertilizer liquid preparation and storage tank. After step four, step five is also included, as follows: Step five: close the valve on the return pipe 13, open the valve on the outlet pipe 12, start the mechanical pump 9, and the agricultural fertilizer liquid is output through the outlet pipe 12.
