[0023] Please see Figure 1 , Figure 2 and Figure 4 The support structure 100 includes a support base 110, an electromagnetic armature assembly 120, a vibration damping and transmission assembly 130, and a support chassis 150. The top surface of the support base 110 has a through hole 112. The electromagnetic armature assembly 120 is installed inside the support base 110 and between the support chassis 150. The vibration damping and transmission assembly 130 is circumferentially installed between the support base 110 and the support chassis 150.
[0024] A support pad 111 is fixed to the bottom of the support base 110. The support pads 111 are symmetrically distributed at the bottom of the support base 110 and are used to support the support base 110 and keep it away from the ground. The electromagnetic armature assembly 120 includes a support block 121, an iron core 122, and an armature 124. The support block 121 is fixed to the bottom of the support base 110. The iron core 122 is mounted on the support block 121, and a coil 123 is mounted on the iron core 122. The armature 124 is mounted on the support chassis 150. Here, the electromagnetic armature assembly 120 is the vibration source used to make the support chassis 150 vibrate. A control button assembly 140 is installed on the support base 110. The control button assembly 140 is electrically connected to the electromagnetic armature assembly 120 and is used to control the electromagnetic armature assembly 120 to generate vibrations of different amplitudes, thereby adapting to the vibration requirements of different raw materials.
[0025] Connecting plates 1221 are fixed to both the iron core 122 and the armature 124. The connecting plates 1221 are connected to the support block 121 and the support chassis 150 via bolts 1222. The connection plates 1221 and bolts 1222 facilitate the installation of the electromagnetic armature assembly 120. Four sets of vibration damping and transmission assemblies 130 are circumferentially distributed. Each vibration damping and transmission assembly 130 is inclined at an angle between 30 and 60 degrees. Each vibration damping and transmission assembly 130 includes a leaf spring 131, with a first mounting seat 132 and a second mounting seat 133 installed at both ends. The first mounting seat 132 is installed inside the support base 110, and the second mounting seat 133 is installed on the support chassis 150. The vibration damping and transmission assembly 130 provides greater stability to the vibration of the support chassis 150. The vibration damping and transmission assembly 130 is inclined at an angle between 30 and 60 degrees.
[0026] Please see Figures 1-3 The screening structure 200 includes a screen frame 220 and a screen frame fixing member 230. The screen frame 220 is placed on the support base 150, and the screen frame fixing member 230 is installed on the support base 150 to fix the screen frame 220.
[0027] The screen frame fixing component 230 includes two sliding rods 231 and a clamping device 232. The two sliding rods 231 are fixed on both sides of the top surface of the support base 150. The clamping device 232 is movably installed on the sliding rods 231 to fix the screen frame 220. The screen frame fixing component 230 is used to fix the screen frame 220 more stably to the support base 150, thereby improving the vibration stability of the screen frame 220. Several screen frames 220 are provided, and several screen frames 220 are stacked together. The screen holes of the several screen frames 220 are set from large to small. The arrangement of several screen frames 220 can screen raw materials of different particle sizes.
[0028] Specifically, the working principle of this new electromagnetic screen is as follows: In use, several screen frames 220 are placed on the support base 150, and the screen frames 220 are positioned and fixed by the clamping device 232. The raw material is placed on the top screen frame 220. Then, the electromagnetic armature group 120 generates magnetic field vibration, and the vibration is realized through the vibration damping and transmission group 130. With the cooperation of the control button group 140, the vibration magnitude and vibration time can be infinitely adjusted. In this way, the raw material on the screen frame 220 will be quickly graded and screened, achieving rapid inspection, thereby greatly improving work efficiency and reducing work intensity. Using the electromagnetic armature group 120 as the vibration source can reduce the control circuit, which is more conducive to reducing faults and reducing the difficulty of troubleshooting. At the same time, it can adapt to the screening needs of different raw materials, making the screening more accurate and more convenient to use.
