[0025] Among them, the driving assembly 2 includes a first fixing plate 22, a second fixing plate 23, a driving screw 24, a driving end 25, and a driving block. The first fixing plate 22 and the second fixing plate 23 are respectively fixedly connected to the bottom plate 21 along the length direction. One end of the driving screw 24 is rotatably connected to the first fixing plate 22 and extends outward to be connected with the driving end 25, the middle part is threadedly connected with the driving block, and the other end is rotatably connected to the second fixing plate 23. Specifically, the driving end 25 can be a rotating handle or a driving motor. Guide rods are symmetrically fixedly connected between the first fixing plate 22 and the second fixing plate 23. The two ends of the driving block are respectively slidably connected to the two guide rods. The bottom ends of the two first connecting rods 31 are respectively hinged to the two ends of the driving block of the left driving assembly 2, and the bottom ends of the two second connecting rods 32 are respectively hinged to the two ends of the driving block of the right driving assembly 2. The first connecting rod 31 and the second connecting rod 32 on the same side of the two driving assemblies 2 are cross-arranged and both are provided with sliding fit grooves 33 in the middle. A sliding fit shaft 34 is connected in the sliding fit groove 33 in a matching manner. The top ends of the two first connecting rods 31 are respectively hinged to the two ends on the left side of the driving plate 4, and the top ends of the two second connecting rods 32 are respectively hinged to the two ends on the right side of the driving plate 4. An installation plate 41 is fixedly connected to the driving plate 4. And, for the convenience of installation, the area of the installation plate 41 is larger than the area of the driving plate 4.

[0026] Specifically, a feeding assembly 5 is fixedly connected to the mounting plate 41 through symmetrically arranged fixing seats 6. The feeding assembly 5 includes a feeding motor 51, a barrel 52, a feeding pipe 53, and a discharging pipe 54. The output end of the feeding motor 51 extends into the barrel 52 and is connected to a spiral conveyor rod. One end of the barrel 52 close to the feeding motor 51 is provided with a feeding pipe 53, and the other end is provided with a discharging pipe 54. The discharging pipe 54 is located outside the mounting plate 41. By arranging the fixing seats 6 at symmetric positions, the feeding assembly 5 can be evenly stressed, enhancing the stability and balance of the overall structure, helping to reduce vibration and noise, and improving the running stability of the equipment. At this time, the tight connection between the fixing seat 6 and the mounting plate 41 makes the feeding assembly 5 a whole, reducing looseness and wear between components and extending the service life of the equipment. Among them, the feeding assembly 5, as an independent module, can be conveniently connected and integrated with the mounting plate 41. This modular design improves the flexibility of the equipment.

[0027] And, as Figure 3 shown, the fixing seat 6 includes an upper fixing plate 61, a lower fixing plate 62, and a fixing member 63. The two ends of the upper fixing plate 61 are respectively provided with upper fixing ends 611, and an upper arc-shaped groove 612 is opened in the lower part. The lower fixing plate 62 includes a fixing main body 621 and a lower fixing end 623. A lower arc-shaped groove 622 is opened in the upper part of the fixing main body 621. The upper arc-shaped groove 612 and the lower arc-shaped groove 622 are correspondingly arranged and can accommodate the barrel 52 after being buckled. The lower fixing ends 623 are symmetrically fixedly connected to both sides of the fixing main body 621 and are provided with fixing holes 624. The lower fixing ends 623 are fixedly connected to the mounting plate 41 through the fixing holes 624, and the fixing member 63 connects the upper fixing ends 611 and the fixing main body 621.

[0028] Optionally, as Figure 4 shown, the fixing member 63 can be a fixing bolt. Bolt holes are correspondingly opened on the upper end faces of the upper fixing ends 611 and the fixing main body 621. The fixing bolt realizes the connection between the upper fixing ends 611 and the fixing main body 621 by cooperating with the two bolt holes. At this time, through the cooperation of the fixing bolt and the bolt holes, the connection between the upper fixing ends 611 and the fixing main body 621 can be quickly realized. This connection method does not require complex tools or techniques, reducing the installation difficulty and cost. And when it is necessary to disassemble or replace the barrel 52, only need to loosen the bolt to easily separate the upper fixing ends 611 and the fixing main body 621, facilitating subsequent maintenance and repair work. In specific use, first fixedly connect the lower fixing ends 623 of the lower fixing plate 62 to the mounting plate 41 through the fixing holes 624, then place the barrel 52 on the lower fixing plates 62 of the two fixing seats 6, and then realize the fixation of the barrel 52 through the cooperation of the fixing bolt and the bolt holes.

[0029] Optionally, as Figure 5As shown, the fixing member 63 can also be a connecting bolt and a connecting nut. A first mating hole is formed through the bottom of the fixing main body 621 upwards, and a second mating hole is correspondingly formed in the upper fixing end 611. The connecting bolt sequentially passes through the first mating hole and the second mating hole upwards and then is connected to the connecting nut. By rotating the nut, a pre-tightening force can be generated to tightly fix the fixing main body 621 and the upper fixing end 611 together. In specific use, first place the cartridge 52 on the lower fixing plate 62 of the fixing seat 6, and then two connecting bolts sequentially pass through the first mating hole and the second mating hole upwards and then are connected to the connecting nut to fix the cartridge 52. Then, fix the lower fixing end 623 of the lower fixing plate 62 to the mounting plate 41 through the fixing hole 624.

[0030] To improve the stability of the overall device support, as Figure 1 , Figure 2 shown, the automatic phosphogypsum feeding device for a full-automatic papermaking production line according to an embodiment of the present invention further includes a support assembly 7. The support assembly 7 includes a threaded connection seat 71, an adjustment screw 72, and a base 73. Threaded connection seats 71 are fixedly connected to the outer sides of the four columns of the frame body 1 respectively. The threaded connection seat 71 is internally threaded with an adjustment screw 72. The bottom end of the adjustment screw 72 is fixedly connected to the base 73. Preferably, the bottom surface of the base 73 is circular. At this time, the support assembly 7 is connected to the base 73 through the threaded connection seats 71 and the adjustment screws 72 on the outer sides of the four columns, forming a stable support structure, making the frame body 1 more stable. Moreover, the adjustment screw 72 is connected to the threaded connection seat 71 through threads, and its bottom end is fixedly connected to the base 73. By rotating the adjustment screw 72, its position in the threaded connection seat 71 can be adjusted, thereby realizing the height adjustment of the entire support assembly 7. The base 73 is the contact part between the support assembly 7 and the ground or other support surfaces. Its bottom surface is designed to be circular. The circular bottom surface helps to increase the contact area with the support surface, improve stability, and reduce the risk of damage caused by pressure concentration.

[0031] Moreover, the frame body 1 in this embodiment adopts a rectangular frame, and a reinforcing connecting plate 11 with a triangular cross-section is arranged between two adjacent horizontal columns at the bottom to improve the stability of the support of the frame body 1. Among them, the structure of the rectangular frame is relatively simple, easy to process and assemble, reducing the manufacturing cost. In addition, the rectangular frame also has good space utilization rate and can accommodate more equipment and components. Specifically, a counterweight can be arranged at the bottom inside the rectangular frame to effectively enhance the structural stability and reduce vibration. Moreover, the counterweight should be firmly fixed to the frame to prevent it from moving or falling off during operation. The fixing method can adopt bolt connection, welding or other reliable mechanical connection methods.

[0032] When the phosphogypsum feeding device for the full-automatic papermaking production line in this embodiment is in use, first, according to actual usage requirements, the height and angle of the material cylinder 52 are adjusted. At this time, the driving end 25 drives the driving screw 24 to rotate, thereby realizing the left and right movement of the driving block on the driving screw 24. Through the symmetrically arranged driving components 2, the bottom positions of the first connecting rod 31 and the second connecting rod 32 can be adjusted respectively. Since the first connecting rod 31 and the second connecting rod 32 are cross-arranged and connected in the middle through a sliding fit shaft 34, the height and position of the tops of the first connecting rod 31 and the second connecting rod 32 can be further adjusted, thereby realizing the adjustment of the height and angle of the material cylinder 52. Then, the phosphogypsum raw material is put into the feeding pipe 53. After the feeding motor 51 operates, the spiral conveying rod rotates under the drive of the feeding motor 51, and pushes the phosphogypsum raw material forward along the spiral track to the discharge pipe 54 to achieve feeding.

[0033] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
