[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 show, two brackets 404 are fixed to one side of the support plate 401, and a limit ring 405 is fixed to one side of each of the two brackets 404. A rotating ring 406 is fixed to the outer side of the grinding cylinder 408, and the rotating ring 406 is rotatably connected between the two limit rings 405. A toothed ring 407 is fixed to the outer side of the rotating ring 406. When the grinding cylinder 408 rotates, the rotating ring 406 rotates between the two limit rings 405, which is convenient for playing a limiting role.

[0022] In this embodiment, as Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the blank holding mechanism 409 includes a first oil cylinder 4091, and the first oil cylinder 4091 is symmetrically and fixedly arranged on the two inner walls of the grinding cylinder 408. The upper side of the first oil cylinder 4091 is connected to a movable column 4093 through a first compression spring 4092, and a roller 4094 is rotatably connected to the top of the movable column 4093. The first compression spring 4092 functions to support the movable column 4093.

A grinding block 413 is fixed to one side of the top of the belt transmission assembly 412. The belt transmission assembly 412 can operate under the action of the first motor 411, thereby driving the grinding block 413 to rotate rapidly. The rotation direction of the grinding block 413 is opposite to the rotation direction of the grinding cylinder 408, which is convenient for automatically grinding fertilizers.

[0026] In this embodiment, asFigure 2 and Figure 4 As shown in Figure 4 , on the other side of the top of the belt drive assembly 412, it is connected to the gear 415 through the connecting shaft 414. The gear 415 is meshed and connected to one side of the toothed ring 407. The operation of the belt drive assembly 412 can drive the connecting shaft 414 and the gear 415 to rotate. Since the toothed ring 407 and the gear 415 are meshed and connected together, the swivel ring 406 and the grinding cylinder 408 can rotate along with the rotation of the gear 415.

[0027] In this embodiment, as Figure 2 、 Figure 4 and Figure 8 As shown in Figure 8 , a cam 416 is fixed to the bottom of the belt drive assembly 412. A second compression spring 417 is fixed to an inner wall of the support frame 410, and a movable block 418 is fixed to one end of the second compression spring 417. The operation of the belt drive assembly 412 can drive the cam 416 to rotate. At this time, the movable block 418 can move back and forth left and right under the extrusion of the cam 416 and the propping of the second compression spring 417.

The stirring frame 419 penetrates through one side of the support frame 410 and is connected to the movable block 418. The left and right reciprocating movement of the movable block 418 can drive the stirring frame 419 to move back and forth left and right, facilitating the automatic stirring of the materials and avoiding the situation of material blockage.

[0029] In this embodiment, as Figure 2 As shown in Figure 2 , a second motor 5 is fixed inside the top of the mixing tank 1, and the bottom of the second motor 5 is connected to the stirring rod 6. A transparent plate 7 is inlaid on the front side of the mixing tank 1, and an electric valve 8 is fixed to the bottom of the mixing tank 1. The stirring rod 6 can rotate under the action of the second motor 5, facilitating automatic mixing. The mixing situation can be observed through the transparent plate 7. After mixing is completed, the electric valve 8 can be opened to discharge the liquid fertilizer.

[0030] The usage method and advantages of the present invention: The mixing equipment for preparing the liquid fertilizer works as follows: As Figures 1 to 8As shown: First, water and solid fertilizer are respectively introduced into the water inlet pipe 2 and the feed pipe 402. After the solid fertilizer enters the grinding cylinder 408, the gap between the grinding cylinder 408 and the grinding block 413 gradually becomes smaller. The belt drive assembly 412 operates to drive the grinding block 413 to rotate. At the same time, the connecting shaft 414 and the gear 415 rotate, thereby driving the grinding cylinder 408 to rotate. The grinding block 413 rotates faster than the grinding cylinder 408, and the rotation direction of the grinding block 413 is opposite to that of the grinding cylinder 408, so as to automatically grind the fertilizer. At the same time, the movable column 4093, the roller 4094 and the first piston 4095 move up and down under the extrusion of the extrusion ring 403 and the support of the first compression spring 4092. The roller 4094 rolls on the extrusion ring 403, and the second piston 4098 and the pressure ring 4099 move up and down, so as to repeatedly press the material downward and assist grinding by extrusion. The cam 416 rotates together with the belt drive assembly 412. The movable block 418 and the stirring frame 419 move left and right under the extrusion of the cam 416 and the support of the second compression spring 417, so as to automatically stir the fertilizer, avoid material blockage, and facilitate auxiliary rapid feeding. The stirring rod 6 rotates to fully mix the water and the ground fertilizer together. After mixing, the electric valve 8 is opened to discharge the liquid fertilizer.

[0031] In summary, the mixing equipment for preparing liquid fertilizer achieves the purpose of automatic and repeated material pressing and anti-blocking, and meets the usage requirements of people.
