[0042] like Figure 2-Figure 4 As shown, a first conveying auger (4) is arranged at the output shaft of the conveying motor (3) and includes a first shaftless auger piece (42);

[0043] The first conveying auger (4) includes a connecting mounting block (41), the connecting mounting block (41) is connected to the output shaft of the conveying motor (3) through a screw, a first shaftless auger piece (42) is provided at one end of the connecting mounting block (41) away from the output shaft of the conveying motor (3), a first connecting tube (43) is provided at one end of the first shaftless auger piece (42) away from the connecting mounting block (41), and the first shaftless auger piece (42) is provided on the outer surface of the first connecting tube (43);

The setting of the first shaftless auger piece 42 makes the shaftless auger more suitable for materials with higher viscosity than the shafted auger, and it is more difficult to get blocked.

[0046] like Figure 2 、 Figure 3 、 Figure 8 as well as Figure 9 As shown, the crushing single roller (6) is connected to the first conveying auger (4) via a snap-fit ​​connection (5);

[0051] Based on the above, the setting of the connecting prism 52 and the threaded side hole 53 enables the snap-fit ​​connector 5 to be connected to the first conveying auger 4 and the second conveying auger 7 respectively through screws. After the connection, the setting of the connecting groove 58 allows the crushing single roller 6 and the auger connector 8 to be snapped into the interior of the connecting groove 58 to achieve the snap-fit ​​effect. At this time, the sealing block 56 is continued to be installed by screws, so that the crushing single roller 6 and the auger connector 8 are respectively connected to the snap-fit ​​connector 5 sufficiently stably.

[0052] like Figure 2 、 Figure 3 as well as Figure 10 As shown, the second conveying auger (7) is connected to the crushing single roller (6) via a snap-fit ​​connector (5) and includes a second shaftless auger piece (71);

[0053] The second conveying auger (7) includes a second shaftless auger piece (71), and both ends of the second shaftless auger piece (71) are provided with a second connecting tube (72).

[0054] Based on the above, the second shaftless auger piece 71 can transport phosphogypsum with higher viscosity, and it is less likely to be blocked during the transportation process. Through the setting of the second prismatic blind hole 73 and the second connecting side hole 74, the second conveying auger 7 can be connected to the snap-on connector 5 by screws.

[0055] like Figure 2 、 Figure 3 、 Figure 11 as well as Figure 12 As shown, the auger connector (8) is connected to the second conveying auger (7) via a snap-on connector (5);

[0056] The auger connector (8) includes a connecting main rod (81), and second guide blocks (82) are provided at both ends of the connecting main rod (81). The second guide blocks (82) are truncated cone blocks.

[0057] The first clamping block (63) and the second guide block (82) are both dovetail protrusions, the first clamping block (63) and the second guide block (82) are both equidistantly distributed and have a one-to-one correspondence with the clamping slot (54), respectively, and the sizes of the first clamping block (63) and the second guide block (82) are consistent with the sizes of the clamping slot (54);

[0058] Based on the above, the auger connector 8 plays a role in connecting two adjacent second conveying augers 7, so that the two adjacent second conveying augers 7 can be connected to each other through the clamping connector 5 and the auger connector 8.

[0059] In actual use, the present embodiment can be provided with the first conveying auger 4, the second conveying auger 7 and the crushing single roller 6, which not only makes it less likely for blockage to occur, but also the crushing single roller 6 can crush the agglomerated phosphogypsum, further avoiding the occurrence of blockage.

[0060] The arrangement of the clamping connector 5 makes it easy to disassemble the crushing roller 6. When disassembling, the blocking block 56 can be removed, and the connecting groove 58 can be ensured to face upwards. At this time, the crushing roller 6 is worked, so that the first clamping block 63 is pulled out from the clamping groove 54. When installing, the operation can be reversed.

[0061] The setting of the auger connector 8 makes it easier to disassemble the second conveying auger 7, and the disassembly and installation process are consistent with the method of the crushing single roller 6;

[0062] The feeding device can not only be installed with a crushing single roller 6 for crushing according to actual conditions, but also, through the setting of a shaftless auger, makes it less likely for blockage to occur when conveying materials with high viscosity such as phosphogypsum, and the crushing single roller 6 and the second conveying auger 7 can be disassembled separately, which is convenient for disassembly.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
