In this embodiment, a cylinder is selected for the first telescopic rod 10, and a second hinge seat 11 is hinged on the piston end of the first telescopic rod 10, and the second hinge seat 11 is connected to the material door 8; By setting a first telescopic rod 10, the material door 8 can be driven to change its angle to realize the opening and closing of the material port 15; a side port of the shell 3 is connected to a first flange plate 12, and the shape of the first flange plate 12 is U-shaped. The first flange plate 12 is connected to a side plate 13 by bolts, and a spiral conveying mechanism 14 is installed on the side plate 13. The number of spiral conveying mechanisms 14 is 2, and the 2 spiral conveying mechanisms 14 are symmetrically arranged; the other side port of the shell 3 serves as the material port 15, and the outer side of the material port 15 is connected to a second flange plate 16, and the shape of the second flange plate 16 is U-shaped. When the material door 8 contacts the second flange plate 16, the material port 15 is closed; the present application limits the structure of the casing 2 so that no siltation space is formed at the material port 15. By setting a material door 8 that can be opened and closed, the rare earth moving in one direction can be quickly discharged, and blockage at the material port 15 is avoided, thereby ensuring continuous unloading and bagging of the rare earth.

[0046] like Figure 4 As shown, as an optimization of the first embodiment, the frame 1 includes a foot 17, the number of the foot 17 is 4, and the four foot 17 are arranged in a matrix, the foot 17 is connected to a column 18, the top surface of the column 18 is connected to the top plate 4, the long side gap of the column 18 is connected to a cross beam 19, the short side gap of the column 18 is connected to a first longitudinal beam 20, the top surface of the first longitudinal beam 20 is in contact with the bottom surface of the casing 2, the first longitudinal beam 20, the cross beam 19, and the column 18 form a stable supporting structure, and a reinforcing rib 21 is connected at the angle between the cross beam 19 and the column 18; the short side gap of the column 18 is connected to a second longitudinal beam 22, and the second longitudinal beam 22 is located below the first longitudinal beam 20. By limiting the structure of the frame 1, it is ensured that the casing 2 can be stably supported.

[0047] like Figure 3 As shown, as an optimization of the first embodiment, the outer wall of the shell 3 is welded with reinforcing plates 23 arranged at equal intervals, and the reinforcing plates 23 are U-shaped. The reinforcing plates 23 can improve the structural strength of the housing 2.

[0048] like Figure 5As shown, as an optimization of Example 1, the feed hopper 5 is in the shape of a cone, the upper diameter of the feed hopper 5 is larger than the lower diameter, the feed hopper 5 is used to collect the rare earth dropped from the conveyor belt, and further, the inner wall of the feed hopper 5 is fixed with a polytetrafluoroethylene plate 24 by screws, and the polytetrafluoroethylene plate 24 can prevent the dropped rare earth from wearing the feed hopper 5, so that no metal impurities are mixed into the rare earth.

[0049] like Figure 6 As shown, as an optimization of the first embodiment, the screw conveying mechanism 14 includes a worm gear motor 25, the worm wheel of the worm gear motor 25 is connected to a rotating shaft 26, the worm gear motor 25 is connected to the side plate 13, and the side plate 13 has an axial hole through which the rotating shaft 26 passes; the side wall of the rotating shaft 26 is connected to a shaftless propeller blade 27, the shaftless propeller blade 27 is used to convey rare earths, and compared with the shafted propeller blade, the free end of the shaftless propeller blade 27 is close to the material port 15, there are fewer places for dirt and grime to accumulate, and no blockage will occur when conveying rare earths.

[0050] like Figure 7~Figure 9 As shown, as an optimization of the first embodiment, a support plate 28 is welded to the vertical section of the shell 3, and two support plates 28 are arranged symmetrically. A lining plate 29 is fixed to the support plate 28 by bolts. The lining plate 29 protects the inner wall of the shell 2. The bottom shape of the lining plate 29 is an arc shape, which is adapted to the shaftless propeller blade 27. The middle of the lining plate 29 has an upward protrusion 30, and the protrusion 30 enables the lining plate 29 to form two conveying channels. The upper end of the protrusion 30 is ridge-shaped, and the protrusion 30 can guide the falling rare earth, and the rare earth will evenly enter the two conveying channels. The horizontal section of the shell 3 is connected with a fixed protrusion 30. The vertical support 31 can improve the installation stability of the liner 29; a first baffle 32 is provided on one side of the liner 29, and the first baffle 32 is used to block the rare earth in the two conveying channels. The first baffle 32 has an axial hole through which the rotating shaft 26 passes; a second baffle 33 is provided on the other side of the liner 29, and the second baffle 33 is used to block the gap between the shell 3 and the liner 29, and the second baffle 33 does not block the rare earth in the two conveying channels, which can ensure the discharge of the rare earth and prevent the rare earth from entering the gap between the shell 3 and the liner 29. By limiting the structure of the liner 29, the transportation efficiency of the rare earth can be improved.

[0051] like Fig.10 As shown, as an optimization of the first embodiment, considering the structural stability of the casing 2, the vertical sections of the casing 2 are gap-connected with connecting rods 34, and a plurality of connecting rods 34 are equidistantly arranged. By providing the connecting rods 34, the structural stability of the casing 2 can be improved and deformation of the casing 2 can be avoided.

[0052] like Figure 1As shown, as an optimization of the first embodiment, a U-shaped frame 35 is fixed to the top surface of the feed hopper 5 by bolts, and a level meter 36 is installed on the U-shaped frame 35. The initial state of the level meter 36 is horizontal. When blockage occurs in the casing 2, rare earth accumulates in the feed hopper 5 until the rare earth triggers the level meter 36 and the machine stops. The level meter 36 can ensure the safety of production.

[0053] like Fig.11 As shown, as an optimization of the first embodiment, taking into account that the deadweight of the shaftless propeller blade 27 causes uneven force on the rotating shaft 26, the other end of the shaftless propeller blade 27 is connected to an auxiliary shaft 37, and a bearing seat 38 is rotatably connected to the auxiliary shaft 37. The bearing seat 38 is connected to the cover plate 6. By providing the auxiliary shaft 37, the operating stability of the shaftless propeller blade 27 can be improved.

[0054] like Fig.12 As shown, and Fig.26 As shown, as an optimization of the first embodiment, considering that the rare earth will adhere to the second flange plate 16 (i.e., the contact surface between the material door 8 and the second flange plate 16) when falling, and the material door 8 is not closed tightly when it is closed, a cylinder seat 39 is installed on the cover plate 6, and the number of cylinder seats 39 is 2. A second telescopic rod 40 is installed on the cylinder seat 39. The piston end of the second telescopic rod 40 is connected to a scraper 41. The scraper 41 moves vertically downward. The scraper 41 is used to clean the rare earth adhered to the second flange plate 16 to ensure that the material door 8 is closed tightly. Fig.11 It can be seen that the horizontal section of the hinge 7 is located on the top surface of the cover plate 6, and the hinge point protrudes outside the second flange plate 16. Therefore, when the material door 8 is buckled with the second flange plate 16, a right-angle space is formed at the hinge point of the hinge 7 (the hinge is two plates, and the two plates are hinged by an axis). This right-angle space is used to accommodate the scraper 41. When scraping is not needed, the scraper 41 is in the right-angle space, and the scraper 41 is in contact with the second flange plate 16. The piston end of the second telescopic rod 40 can pass through the right-angle space. When scraping is needed, the material door 8 is in an open state, and the second telescopic rod 40 pushes the scraper 41 down to scrape off the rare earth on the second flange plate 16, so that the second flange plate 16 is clean. When the material door 8 needs to be closed, the second telescopic rod 40 drives the scraper 41 to rise and stop in the right-angle space, and then the material door 8 can be closed tightly. like Figure 13~Figure 15As shown, as an optimization of the first embodiment, considering that the shaftless propeller blade 27 may adhere to the rare earth, the axis of the rotating shaft 26 has a first through hole 42, and a shaft 43 is rotatably connected in the first through hole 42. The center of the auxiliary shaft 37 preferably has a second through hole 44, and the second through hole 44 is rotatably connected to the shaft 43. The shaft 43 is driven by a first motor 45. The side wall of the shaft 43 between the rotating shaft 26 and the auxiliary shaft 37 is provided with staggered grooves 46, and a rubber sheet 47 is fixed in the groove 46 by screws. The rubber sheet 47 is bent in a normal state. When the shaft 43 rotates, the centrifugal force causes the rubber sheet 47 to hit the shaftless propeller blade 27 to clean up the adhered rare earth. The bending part of the rubber sheet 47 is preferably connected to a tension spring 48, and the free end of the tension spring 48 is connected to the shaft 43. The tension spring 48 causes the rubber sheet 47 to bend to prevent the rubber sheet 47 from affecting the shaftless propeller blade 27 to transport the rare earth.

[0055] like Fig.16 and Fig.17 As shown, as an optimization of the first embodiment, considering that rare earth may adhere to the connection between the rotating shaft 26 and the shaftless propeller blade 27, the side wall of the rotating shaft 26 is fixedly connected with a first sleeve 49, and the side wall of the first sleeve 49 is connected with a first convex plate 50 and a second convex plate 51, the angle between the first convex plate 50 and the second convex plate 51 is an acute angle, a bolt hole 52 is opened on the second convex plate 51, and a buffer bolt 53 is installed on the bolt hole 52, and the buffer bolt 53 can block the impact of the first lever 55; the rotating shaft 26 is rotatably connected with a first cam 54, the first cam 54 is in the shape of a snail, and the first lever 55 is connected to the first cam 54, the first lever 55 is located at the notch of the first cam 54, the first lever 55 is located between the first convex plate 50 and the second convex plate 51, and the first lever 55 is driven by the first convex plate 50 to generate clockwise rotation; the lining plate 29 is installed with a The first slide seat 56 is slidably connected with a first slide bar 57, which is displaced in the vertical direction. The lower end of the first slide bar 57 is rotatably connected with a first roller 58, which is located directly above the first cam 54. The first roller 58 is rollingly connected with the first cam 54. The rotating shaft 26 rotates, driving the first sleeve 49 to rotate synchronously. The first convex plate 50 drives the first lever 55, and then the first cam 54 starts to rotate. The first cam 54 drives the first slide bar 57 to rise. When the first slide bar 57 exceeds the highest position, due to the structure of the first cam 54, the first slide bar 57 will automatically fall down and hit the notch of the first cam 54. The vibration generated during the collision is transmitted to the rotating shaft 26 and the shaftless propeller blade 27, shaking off the rare earth adhered to the connection between the rotating shaft 26 and the shaftless propeller blade 27, thereby ensuring the conveying efficiency of the screw conveying mechanism 14. Similarly, the first sleeve 49 can also be set on the auxiliary shaft 37. The components of this embodiment can be made of non-metallic materials, such as resin and plastic.

[0056] like Fig.18 and Fig.19 As shown, as an optimization of the first embodiment, considering that the bottom surface of the lining plate 29 will be coated with rare earth, the side wall of the rotating shaft 26 is connected to a second sleeve 59, and a dart board 60 is connected to the second sleeve 59.

Driven by the dart board 60, the lower end of the second slide bar 62 is connected to the first hammer 64; the bottom surface of the lining plate 29 is connected to the first impact seat 65, the first impact seat 65 is used to withstand the impact of the first hammer 64, the first impact seat 65 is connected to the first bellows 66, the upper end of the first bellows 66 is connected to the second slide bar 62, by setting the first bellows 66, it can prevent rare earth from entering the gap between the first hammer 64 and the first impact seat 65, by setting the dart board 60, it can drive the first hammer 64 to impact the first impact seat 65, the vibration generated can shake off the rare earth on the bottom surface of the lining plate 29, and ensure the conveying efficiency of the spiral conveying mechanism 14. Similarly, the second sleeve 59 can also be set on the auxiliary shaft 37. The components of this embodiment can be made of non-metallic materials, such as resin and plastic.

The large diameter end of the pipe body 69 is located on the inner side of the lining plate 29, and the small diameter end of the pipe body 69 is located on the outer side of the casing 2. The small diameter end of the pipe body 69 is used to connect the gas pipe 70; an air injection hole 71 is provided in the center of the pipe body 69, and an exhaust hole 72 connected to the air injection hole 71 is provided on the side wall of the pipe body 69. A rubber air disc 73 is slidably connected to the pipe body 69. The rubber air disc 73 is used to cover the inner side wall of the lining plate 29. The exhaust hole 72 is located at the rubber In the rubber air disc 73, a clamping ring 74 is slidably connected to the tube body 69, and a first spring 75 is sleeved on the tube body 69.

When the rubber air disc 73 is reset, it hits the inner wall of the lining plate 29, which can shake off the rare earth coated on the inner side of the lining plate 29, thereby ensuring the conveying efficiency of the spiral conveying mechanism 14.

[0058] like Fig. 22As shown, the second embodiment is different from the first embodiment in that, considering that rare earth may adhere to the connection between the rotating shaft 26 and the shaftless propeller blade 27, the side wall of the rotating shaft 26 is connected to a third shaft sleeve 77, and the third shaft sleeve 77 is connected to three supporting feet 78, which are arranged at equal angles, and the supporting feet 78 are rotatably connected to a second roller 79; the lining plate 29 is connected to a third slide seat 80, and the third slide seat 80 is slidably connected to a third slide rod 81, and the side wall of the third slide rod 81 is sleeved with a second spring 82, and the second spring 82 is elastically connected between the third slide seat 80 and the pressure plate 83; the lower end of the third slide rod 81 is connected to a pressure plate 83, and the bottom surface of the pressure plate 83 has a first step notch 84 and a second step notch 85, and the first step notch 84 is provided with a second step notch 85.

The second step notch 85 is used to prevent the pressure plate 83 from slipping off the second roller 79. The second roller 79 is driven to rotate counterclockwise by the rotating shaft 26. The second roller 79 pushes the pressure plate 83 to rise. When the second roller 79 is separated from the pressure plate 83, the second spring 82 drives the pressure plate 83 to fall. The next second roller 79 just enters the first step notch 84. The descending pressure plate 83 collides with the second roller 79. The vibration generated during the collision is transmitted to the rotating shaft 26 and the shaftless propeller blade 27, shaking off the rare earth adhered to the connection between the rotating shaft 26 and the shaftless propeller blade 27, thereby ensuring the conveying efficiency of the screw conveying mechanism 14. Similarly, a third sleeve 77 can also be set on the auxiliary shaft 37. The components of this embodiment can be made of non-metallic materials, such as resin and plastic.

When the arc plate 87 falls on the fourth sleeve 86, the arc plate 87 will vibrate the rotating shaft 26, and shake off the rare earth adhered to the rotating shaft 26. When the arc plate 87 rotates to separate from the limiting plate 88, due to its own weight, the arc plate 87 rotates and hits the bottom surface of the liner 29. The vibration generated can shake off the rare earth coated on the bottom surface of the liner 29, thereby ensuring the conveying efficiency of the spiral conveying mechanism 14. Similarly, a fourth sleeve 86 may also be provided on the auxiliary shaft 37. The components of this embodiment may be made of non-metallic materials, such as resin or plastic.

The second impact seat 100 is connected to the second bellows 101, and the upper end of the second bellows 101 is connected to the fourth slide bar 94. By setting the second bellows 101, rare earth can be prevented from entering the gap between the second hammer 99 and the second impact seat 100. By setting the dart board 60, the second hammer 99 can be driven to impact the second impact seat 100, and the vibration generated can shake off the rare earth covered on the bottom surface of the lining plate 29, thereby ensuring the conveying efficiency of the screw conveying mechanism 14. Similarly, a fifth shaft sleeve 89 can also be set on the auxiliary shaft 37. The components of this embodiment can be made of non-metallic materials, such as resin and plastic.
