DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example 1
[0024] A screening and drying device for rare earth ore production, see Figure 1-Figure 4 As shown, it includes a drying box 1, a feed frame 2, a vibrating screen 3, a spring 101, a baffle 11, a heating tube 12, a drying drum 13 and a vibration mechanism. The top of the drying box 1 is connected to the feed frame 2, and the feed frame 2 is made of transparent material to facilitate people to watch the screening situation. The feed frame 2 is set to be wide at the top and narrow at the bottom. A baffle 11 is slidably arranged on the rear side of the drying box 1. The baffle 11 can block the rear side of the drying box 1 to prevent the rare earth ore from falling out after screening. A vibrating screen 3 is slidably arranged on the upper inner side of the feed frame 2. The vibrating screen 3 can screen the rare earth ore. Two springs 101 are connected between the front and rear sides of the top of the vibrating screen 3 and the feed frame 2. A drying drum 13 is rotatably arranged in the middle of the drying box 1. Heating tubes 12 are evenly installed on the outside of the drying drum 13. The heating tube 12 can dry the rare earth ore. A vibration mechanism is arranged on the feed frame 2.
[0025] See also Figure 1 and Figure 3As shown, the vibration mechanism includes a first motor 4, a bevel gear 5, a rotating shaft 51, a first pulley group 6 and a cam 102. The first motor 4 is installed on the front left side of the feed frame 2, and the output shaft of the first motor 4 passes through the right side of the feed frame 2. The upper part of the drying box 1 is rotatably provided with a rotating shaft 51, the left part of the output shaft of the first motor 4 is connected with a bevel gear 5, and the rear side of the rotating shaft 51 is also connected with a bevel gear 5. The two bevel gears 5 are meshed with each other, and the first pulley group 6 is connected between the front part of the rotating shaft 51 and the front part of the drying drum 13. The first pulley group 6 consists of two pulleys and a flat belt. The left and right sides of the output shaft of the first motor 4 are connected with cams 102, and the cam 102 is located below the vibrating screen 3. The rotation of the cam 102 drives the vibrating screen 3 to move up and down, thereby achieving the purpose of vibration screening.
[0026] When the device is needed, people first place the device at a designated position, and then pour the rare earth ore to be screened onto the vibrating screen 3 for screening. At the same time, people start the first motor 4, and the output shaft of the first motor 4 rotates to drive the bevel gear 5 to rotate, and the bevel gear 5 rotates to drive the cam 102 and the rotating shaft 51 to rotate. The rotation of the cam 102 can squeeze the vibrating screen 3 to move upward, and the spring 101 is compressed. When the cam 102 is separated from the vibrating screen 3, the spring 101 returns to its original state, and the vibrating screen 3 can be driven to move downward. In this way, the vibrating screen 3 can intermittently move up and down to achieve the purpose of vibrating and screening the rare earth ore. After screening, the rare earth ore will fall down into the drying box 1, and the rotation of the rotating shaft 51 can drive the drying drum 13 to rotate through the first pulley group 6. The rotation of the drying drum 13 drives the heating tube 12 to rotate, and the heating tube 12 can rotate to evenly dry the rare earth ore. When all the rare earth ore is screened and dried, people turn off the first motor 4, and finally take away the screened and dried rare earth ore.

The threaded rod 7 is rotatably connected to the drying box 1. The threaded rod 7 is also rotatably arranged on the right side of the lower part of the drying box 1. A second pulley set 9 is connected between the threaded rod 7 on the right and the output shaft of the motor. The second pulley set 9 consists of two pulleys and a flat belt. A push plate 14 is threadedly arranged between the front parts of the two threaded rods 7. The push plate 14 can push the rare earth ore backward by moving backward.
[0029] When it is necessary to take away the rare earth ore after screening and drying, people can start the second motor 8. The output shaft of the second motor 8 can rotate through the second pulley set 9 to drive the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the push plate 14 to move backward. The backward movement of the push plate 14 can push the rare earth ore in the drying box 1 backward, making it convenient for people to take it away. After all the rare earth ore is pushed out, the second motor 8 can be turned off.
