Description

Technical Field

[0001] The invention relates to the technical field of water-fertilizer integrated irrigation, and in particular to a water-fertilizer integrated mixing device capable of improving disturbance effect. Background Art

[0002] In modern agricultural production, in order to improve crop yield and quality, more and more agricultural scenarios have begun to adopt integrated water and fertilizer mixing devices, such as facility agriculture, fruit tree cultivation, fields, dry fields, greenhouses and orchards. With the help of a pressure system, it transports the fertilizer liquid in the fertilizer tank and the water source in the water storage tank to the mixing tank through a delivery pipeline for mixing. After the water and fertilizer are mixed, the fertilizer pipeline and dripper are used to evenly, regularly and quantitatively infiltrate the root development and growth area of ​​the crop, so that the soil near the main root of the crop is always loose and has an appropriate water content, ensuring that the crop can obtain the right amount of water and nutrients at different growth stages.

[0003] When the mixing tank in the existing integrated water-fertilizer mixing device mixes water and fertilizer, although the rotating stirring blades can bring certain disturbance and mixing effects to the water and fertilizer, it is difficult to further improve the disturbance and mixing effects of the water and fertilizer only by the stirring action of the stirring blades, so that the efficiency of the fertilizer dissolving in the water is poor, and the stirring action of the stirring blades is not very effective for the fertilizer that has already precipitated, thereby reducing the utilization efficiency of the fertilizer and affecting the fertilization effect. In addition, although a filter is installed at the fertilizer outlet of the mixing tank in the existing integrated water-fertilizer mixing device, the large particles in the mixed water and fertilizer can be filtered through the filter. However, after long-term use, a large amount of impurities are easily blocked in the mesh of the filter, thereby affecting the normal fertilizer delivery work of the integrated water-fertilizer mixing device, and when cleaning the impurities blocked in the mesh, it is necessary to manually disassemble and clear the blockage, thereby reducing the convenience of the integrated water-fertilizer mixing device during use.

[0019] Through the setting of the U-shaped limiting member, the buckle member and the U-shaped clamping block, when it is necessary to perform maintenance work on the internal structure of the fertilizer box, only by manually squeezing the two buckle members in the opposite direction, the U-shaped limiting member and the sealing plate will lose their limiting effect, and then the U-shaped limiting member and the sealing plate can be rotated and opened to perform maintenance work on the internal structure of the fertilizer box. Therefore, during the maintenance work, there is no need to perform cumbersome disassembly work with tools, thus improving the convenience of the maintenance work of this integrated water and fertilizer preparation device.

[0020] Through the setting of the reinforcing screw, after the U-shaped limiting member is closed, by rotating the reinforcing screw, the reinforcing screw can drive the sealing plate to move linearly backward under the action of the thread, so that the rear end face of the sealing plate is in close contact with the front side face of the sealing rubber ring, further improving the sealing effect of the sealing plate.

When the lifting plate 802 moves upward with the ejector rod 803, the corresponding ejector rod 803 will be inserted into the mesh hole of the filter screen plate 508, and the impurities blocked in the mesh will be ejected to avoid affecting the normal fertilizer delivery work of the water-fertilizer integrated mixing device.

[0035] The working principle of this embodiment is as follows: when in use, different fertilizer liquids are added into the three fertilizer liquid tanks 2 respectively, and then clean water is added into the water storage tank 3. According to the actual needs of the crops, the flow values ​​of the three first electromagnetic flow integrated valves 201 and the second electromagnetic flow integrated valves 301 are preset through the control cabinet 4, and then the fertilizer suction pump 101 is started to quantitatively transport the fertilizer liquids in the three fertilizer liquid tanks 2 to the mixing tank 1, and then the water delivery pump 302 is started to quantitatively transport the clean water in the water storage tank 3 to the mixing tank 1. After the fertilizer liquid and clean water enter the mixing tank 1, the mixing motor 103 is started, and the mixing motor 103 drives the stirring shaft 104 to rotate, and the stirring shaft 104 drives the stirring blades to stir the water and fertilizer in the mixing tank 1 to obtain a water-fertilizer mixture; During the stirring movement of the stirring blade, the stirring shaft 104 rotates with the circular driving plate 105, and the circular driving plate 105 drives the driving column 106 to rotate, and then the driving column 106 drives the driving frame 7012, the three hexagonal rods 7011 and the three pistons 7013 to move back and forth. When the piston 7013 moves backward, the external air enters the gas cylinder 702 through the first one-way valve 705 and the first air inlet 703, and when the piston 7013 moves forward, the air inside the gas cylinder 702 enters the gas cylinder 702 through the second air inlet 704 and the second The one-way valve 706 enters into the conduit 707, and then the air enters into the first annular air pipe 708 and the second annular air pipe 709 through the air pipe, and then the air is blown into the water-fertilizer mixture through the air blowing heads at the top of the first annular air pipe 708 and the second annular air pipe 709. By adding air to the water-fertilizer mixture, the disturbance and mixing effect of water and fertilizer can be further improved, which helps the fertilizer to dissolve in the water more quickly and evenly. This is especially important for some solid fertilizers that are not easily soluble, and can improve the utilization efficiency of the fertilizer.

[0036] In addition, during the rotation of the stirring shaft 104, the stirring shaft 104 will rotate with the first bevel gear, the second bevel gear, the first transmission shaft 107, the first pulley, the second pulley, the second transmission shaft 108 and the crankshaft 801, and the rotating crankshaft 801 will rotate the two connecting rod journals 807, and the rotating two connecting rod journals 807 will rotate the lower ends of the two connecting rods 805, and then the upper ends of the two connecting rods 805 will move the two lifting plates 802 and the ejector rod 803 up and down in turn, and when the left lifting plate 802 moves upward, the right lifting plate 802 will move downward, and when the lifting plate 802 moves upward with the ejector rod 803, the corresponding ejector rod 803 will be inserted into the mesh of the filter plate 508 to eject impurities blocked in the mesh, so as to avoid affecting the normal fertilizer delivery work of the water-fertilizer integrated mixing device.
