[0027] This utility model provides a material screening device, such as Figures 1 to 3 As shown, the material screening device in this embodiment includes a housing 1 and a vibration assembly connected to the housing 1. The vibration assembly enables the material in the housing 1 to perform non-linear three-dimensional motion on the surface of the screen 2, thereby allowing the material to fully contact the screen 2 and effectively improving screening efficiency and screening quality. The specific structure and positional relationships of the various components of the material screening device in this embodiment will be described in detail below.

[0028] In this embodiment, as Figure 1 As shown, the shell 1 is formed into a columnar structure, which is composed of multiple screen frames connected sequentially along a first direction (the first direction is the axial direction of the shell 1), and an inner cavity is formed inside the shell 1. Further, a bottom plate 133 is provided in the inner cavity of the shell 1, dividing the inner cavity of the shell 1 into an upper inner cavity 131 and a lower inner cavity 132. The upper inner cavity 131 and the lower inner cavity 132 are respectively distributed at the top and bottom ends of the bottom plate 133 along the first direction. Even further, multiple screens 2 are provided in the upper inner cavity 131 at intervals along the first direction. An inlet 11 communicating with the upper inner cavity 131 is formed at the top of the shell 1, and an outlet 12 communicating with the upper inner cavity 131 is formed on the outer side of the shell 1.

[0029] It should be noted that the formation of the shell 1, the setting of the inlet 11 and the outlet 12 are all existing technologies, and therefore will not be described in detail.

[0030] In this embodiment, as Figures 1 to 2As shown, the vibration assembly includes a polarization mechanism disposed at the bottom end of the housing 1. Specifically, the polarization mechanism includes a sleeve 331, which is screwed to the bottom end of the housing 1 by screws, so that the receiving cavity of the sleeve 331 communicates with the lower inner cavity 132 of the housing 1. More specifically, the polarization mechanism also includes a polarization part disposed in the receiving cavity, which is screwed to the sleeve 331 to transfer kinetic energy to the sleeve 331, and then to the housing 1 by screws, thereby providing the housing 1 with kinetic energy (in the horizontal plane perpendicular to the first direction). Combined with the elastic force of the spring 32, it can mimic the principle of manual sieving, so that the material in the housing 1 performs nonlinear three-dimensional motion (i.e., circular motion, arc motion, and vertical motion superimposed) at the screen 2. Furthermore, such as Figures 1 to 2 As shown, the polarization section includes a motor 334. The axis of the drive shaft of the motor 334 extends along a first direction and is collinear with the axis of the housing 1. The outer shell of the motor 334 is adapted to the receiving cavity and screwed to the inner wall of the receiving cavity. The connection structure between the motor 334 and the receiving cavity is not fixed and is a conventional means in the mechanical field, as long as it can achieve the above-mentioned technical effect of transmitting lateral kinetic energy. In addition, the first end of the drive shaft extends into the lower inner cavity 132, and at least two sets of adjustment components are sleeved on the first end of the drive shaft. The two sets of adjustment components are distributed at intervals along the first direction and are both located in the lower inner cavity 132. In this way, the motor 334 can drive the two sets of adjustment components to perform centrifugal motion. During the centrifugal motion, the adjustment components will generate excitation force, which can be transmitted to the housing 1 through screws as the kinetic energy provided by the polarization section to the housing 1.

[0031] like Figure 2 As shown, the adjustment assembly includes a geared disc 332 sleeved on the outer side of the drive shaft. The end face of the geared disc 332 has multiple perforated holes 3321, which are arranged circumferentially along the disc to form a ring structure. The adjustment assembly also includes two counterweights 333 disposed at the top of the geared disc 332, each counterweight 333 being rotatably connected to the drive shaft. Furthermore, the bottom of each counterweight 333 has a protrusion 3331 that can engage with the perforated holes 3321. When the counterweights 333 rotate to a preset position, such that the two counterweights 333 are distributed at a preset angle, the two counterweights 333 can be fixedly engaged with the geared disc 332 through the protrusions 3331.

[0032] Thus, by changing the weight and position (i.e. the angle between the two counterweights 333 in each set of adjustment components) or by changing the relative position of the upper and lower sets of adjustment components, the corresponding changes in the motion state and motion intensity of the shell 1 can be achieved.

[0033] Furthermore, in this embodiment, such as Figure 1As shown, the material screening device also includes a support base 4. Along the first direction, the two ends of the sleeve 331 and the multiple springs 32 are respectively connected to the support base 4 and the housing 1. When the kinetic energy of the polarization section is transferred to the housing 1, the multiple springs 32 will also shake due to their connection with the housing 1, thereby generating elastic force. This elastic force can act on the housing 1 to superimpose with the kinetic energy generated by the polarization section. In this way, the principle of manual screening can be imitated, so that the material inside the housing 1 makes nonlinear three-dimensional motion at the screen 2.

[0034] like Figure 1 As shown, the ultrasonic generator 31 is located on the outer side of the housing 1. Its specific location and installation method are existing technologies and will not be described further. The ultrasonic generator 31 transmits ultrasonic waves to cause the material to move vertically on the surface of the screen 2.

[0035] In this embodiment, a plurality of screens 2 are arranged sequentially along a first direction in the upper inner cavity 131. Specifically, as shown in the figure... Figure 3 As shown, the screen 2 includes a first connecting frame 211, a second connecting frame 212, and a third connecting frame 213. These three frames are arranged sequentially from the inside out. The third connecting frame 213 is connected to the inner wall of the upper inner cavity 131, meaning it is formed in a circular shape corresponding to the upper inner cavity 131. The output end of the ultrasonic generator 31 is connected to the connection between the third connecting frame 213 and the housing 1 to facilitate the transmission of ultrasonic waves.

[0036] In addition, each screen 2 also has multiple reinforcing frames distributed in a divergent structure, such as Figure 3 As shown, the reinforcing frame includes alternating first reinforcing frames 221 and second reinforcing frames 222. The two ends of the first reinforcing frame 221 are connected to the second connecting frame 212 and the third connecting frame 213, respectively. The two ends of the second reinforcing frame 222 are connected to the first connecting frame 211 and the third connecting frame 213, respectively. The middle of the second reinforcing frame 222 is connected to the second connecting frame 212. Furthermore, the portions of the first reinforcing frame 221 and the second reinforcing frame 222 located between the second connecting frame 212 and the third connecting frame 213 are both formed into a bent structure. Through the frame arrangement described above, the structural strength of the screen 2 itself can be effectively improved, enabling the screen 2 to adapt to the kinetic energy transmitted by the vibration component, effectively improving the service life of the screen 2.

[0037] According to the material screening device described above, a vibration component is connected to the outside of the housing 1 of the screening device. This component includes an ultrasonic generator 31 located on the outer side of the housing 1, a polarization mechanism located at the bottom of the housing 1, and multiple springs 32. The polarization mechanism provides kinetic energy to the housing 1, and the elastic force of the springs 32 is superimposed to simulate the principle of manual screening. This causes the material inside the housing 1 to undergo nonlinear three-dimensional motion (i.e., a superposition of circular motion, arc motion, and vertical motion) at the screen 2. The ultrasonic generator 31 can further provide kinetic energy to the housing 1, allowing the material to make more full contact with the screen surface. Compared with the single motion mode of the material in existing equipment, this device can effectively improve screening efficiency and screening quality.

[0038] In addition, the screen 2 in this device has multiple reinforcing skeletons distributed in a divergent structure, which enables the screen 2 to adapt to the high-intensity movement of materials, effectively improving the screening capacity of the screen 2, and further improving the screening efficiency and screening quality.
