[0002] Organic water-soluble fertilizer is a liquid fertilizer that is a mixture of one or more fertilizers and water. Water-soluble fertilizers are more easily absorbed by vegetation. In the process of mixing water-soluble fertilizers, the corresponding organic water-soluble fertilizer liquid mixing device is needed. Liquid fertilizers, also known as fluid fertilizers, include fertilizers in solution and fertilizers containing suspended solid particles. With the advancement of science and technology and the development of society, the characteristics of a single fertilizer often cannot meet the needs of users. Therefore, for compound organic water-soluble fertilizers, multiple types of fertilizer concentrates will be injected and homogenized in conjunction with the mixing bin.

[0003] The traditional batching machine is equipped with a stirring function. There is a problem of uneven mixing during the mixing period, which is easy to produce precipitation.

[0014] It can be seen from the above technical solutions that the organic water-soluble fertilizer liquid batching device provided in the embodiments of this specification has at least the following beneficial effects: (1) The present invention drives the air pressure cleaning device to replenish gas into the cleaning air cavity in one direction, and uses air pressure to automatically discharge the residual fertilizer liquid in the batching hopper. On the other hand, it transmits power to the spiral transmission filter element through the transmission device, causing it to rotate, move and vibrate, and uses multi-directional movement to achieve efficient material discharge and cleaning, thereby achieving automatic cleaning of the residual fertilizer liquid in the batching hopper and the filter element at the same time, fully solving the problem of cross contamination caused by residual sediment in the fertilizer liquid.

[0015] (2) The present invention starts the active motor, and the output shaft of the active motor drives the connecting arm on the driving arm to move through the worm gear.

[0017] (4) The present invention heats the gas in the heating chamber by means of a heating element. Since the end of the central shaft is fixed to the ferrule, the ferrule slides forward and backward on the key shaft under the influence of the sliding shaft on the central shaft, that is, the ferrule moves forward and backward synchronously during rotation. The ferrule drives the air pressure plate to perform piston movement in the heating chamber through the limit rod. During the movement, the air pressure plate squeezes and sucks the gas between the air pressure plate and the one-way flow base, and realizes one-way transportation of the gas through the piston movement.

[0023] Furthermore, a heat flow chamber 81, a fertilizer chamber 82, and a heating chamber 83 are respectively provided inside the inclined filter base 8. The inclined filter base 8 is fixedly installed on the batching machine 1. The heating chamber 83 is located in the inclined upper end area of ​​the inclined filter base 8, and the fertilizer chamber 82 is located next to the heating chamber 83. The heat flow chamber 81 is located outside the heating chamber 83 in the inclined filter base 8. The inside of the fertilizer chamber 82 is located at the two ends of the spiral transmission filter element 9, and the front metal knocking rod 84 and the rear metal knocking rod 85 are fixedly connected. The spiral transmission filter element 9 will hit the front metal knocking rod 84 and the rear metal knocking rod 85 during the forward and backward movement, and then generate vibration through knocking, thereby promoting the vibration discharge of the sediment blocked on the spiral transmission filter element 9, so as to achieve the effect of automatically cleaning the spiral transmission filter element 9 as a whole, and reduce the problems of cross contamination and filter element blockage caused by residual materials.

[0025] The spiral transmission filter element 9 includes a central axis 91, one end of which is fixedly connected to the end of the ferrule 103, and the two end surfaces of the central axis 91 are respectively movably connected inside the inclined filter base 8. A spiral filter screen 92 is fixedly connected to the central axis 91, and the surface of the central axis 91 is located at the two ends of the spiral filter screen 92, and a front filter plate 93 and a rear filter plate 94 are respectively fixedly connected. The spiral filter screen 92 is provided with an inclined guide edge 95. After the fertilizer liquid passes through the spiral filter screen 92 for layer-by-layer filtration, part of the filtered sediment is blocked on the spiral filter screen 92, and part of it remains between the spirals of the spiral filter screen 92. When the spiral filter screen 92 rotates, the sediment remaining between the spiral filter screens 92 can be spirally transported to the discharge pipe 12 for automatic discharge. The spiral filter screen 92 is provided with an inclined guide edge 95 corresponding to the spiral shape of the spiral filter screen 92, which is an inclined spiral arc surface, which can In order to avoid the problem that the fertilizer liquid remains between the outer edge of the spiral filter 92 and the inner wall of the fertilizer chamber 82 during normal transportation, and then avoid the problem of increased sediment residue contamination due to contact dead angles, the surface of the central axis 91 is located at the limit base 106 and is fixedly connected to the sliding shaft 96, and the interior of the limit base 106 is respectively fixedly connected to the forward tilting disk 1061 and the rearward tilting disk 1062, the forward tilting disk 1061 and the rearward tilting disk 1062 are in a parallel state, and the sliding shaft 96 is movably connected between the forward tilting disk 1061 and the rearward tilting disk 1062. The rotating sliding shaft 96 is affected by the limitation of its surface, which will drive the central axis 91 as a whole to perform a short distance forward and backward movement while rotating, that is, the overall spiral filter 92 will also move forward and backward during rotation, and the power of the forward and backward movement is used to assist in the discharge of sediment between the spiral filter 92, thereby further improving the effect of the spiral filter 92 automatically removing sediment.

[0026] The heating element 107 heats the gas in the heating chamber 83. Because the end of the central axis 91 is fixed to the ferrule 103, the ferrule 103 slides back and forth on the key shaft 101 under the influence of the sliding shaft 96 on the central axis 91, that is, the ferrule 103 moves back and forth synchronously during the rotation. The ferrule 103 drives the air pressure plate 104 to perform piston movement in the heating chamber 83 through the limit rod 105. During the movement, the air pressure plate 104 squeezes and sucks the gas between the air pressure plate 104 and the one-way flow base 13, and realizes one-way transportation of the gas through the piston movement. During the gas transportation, the gas is heated in combination with the heating element 107, and then the heated gas is transported to the hot flow circulation chamber 81, thereby achieving the effect of heating the spiral filter screen 92 in the fertilizer chamber 82 as a whole, and the purpose of softening the solidified sediment on the spiral filter screen 92 is achieved by heating, and the effect of cleaning the solidified sediment on the filter element is further achieved. The air pressure plate 104 is elastically fixed on the ferrule 103 by a spring, so that the air pressure plate 104 can automatically replenish the pressure during the reciprocating squeezing of the gas.

At the same time, the spiral air pipe achieves the effect of maximally increasing the airflow flow path in a limited space, thereby increasing the heating time of the airflow by the heating element 107 and achieving the effect of sufficient heating.

By setting a one-way valve 133 to limit the one-way flow of gas flowing in the fixed base 131, the air pressure plate 104 can only draw air from the spiral air pipe 134 connected to the one-way valve 133 in one direction during the continuous reciprocating movement, and then squeeze the drawn heated gas into the air inlet pipe 132 in one direction. One end of the air inlet pipe 132 and the air outlet pipe 135 are respectively inserted into the hot flow circulation chamber 81, and the hot air is transported to the hot flow circulation chamber 81 through the air inlet pipe 132. The hot air in the hot flow circulation chamber 81 is continuously replenished to achieve the effect of heating the spiral filter screen 92 in the fertilizer chamber 82 as a whole. The heating can achieve the effect of softening the solidified precipitates on the spiral filter screen 92, further achieving the purpose of cleaning the solidified precipitates on the filter element. The hot air replenished in the hot flow circulation chamber 81 is then refluxed to the spiral air pipe 134 from the air outlet pipe 135 at the lower end of the inclined filter base 8 by air pressure, thereby achieving the purpose of gas circulation heating.

[0028] When the organic water-soluble fertilizer liquid batching device of the present invention is in use, the organic water-soluble fertilizer is pre-fed into the batching hopper 2 from the feeding hopper 5 through proportioning. The stirring motor 4 is started to drive the stirring blades to mix and stir the liquid. After the mixing batching is completed, the mixture is fed into the inclined filter base 8 through the connecting pipe. The fertilizer liquid is filtered layer by layer in a spiral manner through the inclined filter base 8 to achieve the effect of multiple filtration. The filtered fertilizer liquid can avoid the problem that the sediment affects the quality of the fertilizer liquid after batching due to uneven mixing during batching. The filtered fertilizer liquid is discharged through the liquid outlet pipe 11. When the first batch of organic water-soluble fertilizer batching is completed, by starting the main motor 71, the output shaft of the main motor 71 drives the connecting arm 74 on the driving arm 73 through the worm 72. Affected by the limited sliding of the piston plate 77 on the connecting seat 75 in the air pressure box 76, the connecting arm 74 can only drive the piston plate 77 to continuously move up and down in the air pressure box 76. During the up and down movement of the piston plate 77, the effect of unidirectional driving of the gas in the air pressure box 76 is achieved. External air enters the air pressure box 76 from the one-way intake valve 78 under the influence of negative pressure, and then is squeezed into the cleaning air chamber 6 through the positive pressure from the connecting pipe 79. The cleaning air chamber 6 is provided with air outlets at the four sides of the bottom surface of the material blocking top cover 3, and the air outlets are aligned with the four inner walls of the batching hopper 2, so as to achieve the effect of automatically feeding the residual fertilizer liquid in the batching hopper 2 by using air pressure. At the same time, the worm 72 meshes with the worm wheel 102, and the worm wheel 102 drives the transmission sleeve 103 to rotate through the key shaft 101. The transmission sleeve 103 drives the central shaft 91 fixedly connected thereto to rotate as a whole. The central shaft 91 drives the spiral filter screen 92 fixedly connected thereto to achieve the effect of spiral conveying and discharging the sediment remaining between the spiral filter screens 92 during rotation. During the discharging and cleaning, the sliding shaft 96 fixed on the central shaft 91 slides between the front inclined disk 1061 and the rear inclined disk 1062. The front inclined disk 1061 and the rear inclined disk 1062 are in an inclined parallel state. Affected by the limitation of the inclination of its surface, the rotating sliding shaft 96 will drive the central shaft 91 to move back and forth for a short distance while rotating as a whole, that is, the overall spiral filter screen 92 will also move back and forth during rotation. The front and back movement effects are used to improve the efficiency of automatic discharging and cleaning of the sediment between the spiral filter screens 92. Moreover, the front filter plate 93 and the rear filter plate 94 that move synchronously with the central shaft 91 will respectively hit the front metal knocking rod 84 and the rear metal knocking rod 85 during the back and forth movement, and then generate vibrations through knocking, promoting the vibrating discharging of the sediment blocked in the spiral transmission filter element 9, achieving the effect of automatically cleaning the whole spiral transmission filter element 9, and reducing the problems of cross-contamination and filter element blockage caused by residual materials.The heating element 107 heats the gas in the heating chamber 83. Since the end of the central shaft 91 is fixed to the ferrule 103, the ferrule 103 slides back and forth on the key shaft 101 under the influence of the sliding shaft 96 on the central shaft 91. That is, the ferrule 103 moves back and forth synchronously during rotation. The ferrule 103 drives the air pressure plate 104 to perform a piston motion in the heating chamber 83 through the limit rod 105. During the movement of the air pressure plate 104, the gas between the air pressure plate 104 and the one-way flow base 13 is squeezed and sucked. The one-way transportation of the gas is realized through the piston motion. During the gas transportation, the gas is heated in combination with the heating element 107, and then the heated gas is transported into the heat flow circulation chamber 81, so as to achieve the effect of heating the entire spiral filter screen 92 in the fertilizer chamber 82. The purpose of softening the solidified sediment on the spiral filter screen 92 is achieved through heating, and further the effect of cleaning the solidified sediment on the filter element is achieved. The hot gas replenished into the heat flow circulation chamber 81 is recycled into the spiral air pipe 134 again through the air outlet pipe 135 at the low end of the inclined filter base 8 by air pressure, so as to achieve the purpose of gas circulation heating.
