[0006] Further comprising a second motor, the second motor is connected with a rotating shaft below the vibrating screen through a belt two, eccentric shaft sleeves are arranged at both ends of the rotating shaft, and the rocker arms are connected with the eccentric shaft sleeves;
[0007] As preferred, the vibrating screen is designed as a louver window, wherein the air deflector is designed to be inclined to the air cover direction, a fan is arranged on the lower side of the vibrating screen, the air outlet of the fan is opposite to the vibrating screen, and a wind bag is connected between the air outlet of the fan and the vibrating screen.
[0008] As preferred, an inlet is arranged above the machine body and extends above the vibrating screen;

[0014] The beneficial effects of this utility model are:
[0015] This utility model provides a dry gravity separator with a simple structure and reasonable design. A first motor starts, driving a blower via a belt. A second motor starts, driving a rotating shaft via a belt, which in turn rotates an eccentric sleeve on the shaft. The rotation of the eccentric sleeve causes the rocker arm mounted on it to push upwards, causing the vibrating screen to vibrate from bottom to top. Because the vibrating screen has a louvered design, with the air guide plate angled towards the hood, the airflow from the blower is guided upwards at an angle, creating a suspension effect on the material under the combined action of vibration and airflow. Under the combined action of the vibrating screen and the air force, the heavier materials on the vibrating screen are carried to the higher end of the screen and discharged through the heavy hopper, while the lighter materials are carried to the lower end of the screen by the vibrating screen and the reverse air force and discharged through the light hopper. This achieves the separation of various minerals with different specific gravities, especially the efficient screening of non-magnetic, weakly magnetic ores, and coal gangue. Moreover, the mineral dust generated in this process is also sucked away by a dust removal device connected to the air outlet. This mineral processing machine is suitable for use in areas with scarce water resources and can also reduce environmental pollution. Attached Figure Description

Detailed Implementation
[0020] The following are specific embodiments of the present invention described in conjunction with the accompanying drawings, further illustrating the technical solution of the present invention. However, the present invention is not limited to these embodiments. Specific details such as particular configurations and components are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.
[0021] like Figs. 1-2 The embodiment shown illustrates a dry gravity separator, comprising: a vibration device and a machine body; the vibration device 100 includes a vibrating screen 110 and a first motor 120; the first motor 120 is mounted on the machine body 200; the first motor 120 is connected to a blower 230 via a belt 211; a left support arm 111, a right support arm 112, and a rocker arm 113 are rotatably mounted on both sides of the vibrating screen 110, and the vibrating screen 110 is rotatably connected to a vibrating screen support 114 via the left support arm 111, the right support arm 112, and the rocker arm 113, the vibrating screen support 114 being fixed on the machine body 200, and the vibrating screen 110 being inclinedly disposed within the machine body 200; a rotating shaft 212 is disposed below the vibrating screen; eccentric bushings 212 are mounted on both ends of the rotating shaft 212; the lower end of the rocker arm 113 is connected to the eccentric bushing 212.
[0022] Furthermore, the vibrating screen 110 is provided with a feed inlet 220 and an air outlet 240, and an air hood 241 is provided below the air outlet 240.
[0023] Specifically, the vibrating screen 110 is equipped with a louvered screen bottom, that is, the air guide plate 119 is inclined towards the air cover 241.
[0024] Furthermore, a fan 230 is provided on the lower side of the vibrating screen 110, the air outlet of the fan 230 is opposite to the vibrating screen 110, and a wind bag 231 is flexibly connected between the air outlet of the fan 230 and the vibrating screen 110.
[0025] Furthermore, baffles 118 are installed on both sides of the vibrating screen 110 to prevent material from leaking to both sides.
[0026] Furthermore, heavy material outlet 250 and light material outlet 260 are respectively provided on both sides of the machine body. The higher end of the vibrating screen 110 is connected to the heavy material hopper 115, and the lower end of the vibrating screen 110 is connected to the light material hopper 116. The heavy material hopper 115 extends out of the heavy material outlet 250, and the light material hopper 116 extends out of the light material outlet 260.
[0027] During operation, the first motor 120 starts the fan 230, the second motor 212 starts the rotating shaft 212, and the external dust removal device 240 starts. Through the reciprocating motion of the rocker arm 113, the vibrating screen 110 is driven to vibrate. During the vibration of the vibrating screen 110, the fan 230 blows air upward, blowing the dust mixed in the material upward. At the same time, the external dust removal device generates a strong suction force. Through the blowing force of the fan 230 and the suction force of the external dust removal device, the dust in the material can be transported to the external dust removal device for dust removal treatment. Since there is a flexible connection between the air outlet of the fan 230 and the vibrating screen 110, the upward blowing air will not leak out.
[0028] Furthermore, the bottom of the vibrating screen 110 is also connected to a dust removal pipe 117, which extends out of the machine body 200.
[0029] Specifically, during the vibration of the vibrating screen 110, some material may fall through the holes on the vibrating screen 110 and flow out of the mineral processing machine through the dust removal pipe 117.
[0030] When using this ore dressing machine, the controller starts and stops the first motor 120, the second motor 212, and the external dust removal device 240, thereby driving the eccentric bushing 213 on the rotating shaft 212 to rotate. The rotation of the eccentric bushing 213 causes the rocker arm 113 mounted on it to push upwards from the bottom, causing the vibrating screen 110 to vibrate from the bottom to the top. Because the vibrating screen 110 has a louvered design, i.e., the air guide plate 119 is inclined towards the air hood 241, the air blown by the fan 230 can be directed diagonally upwards. Guided by the airflow, under the combined action of the vibrating screen 110 and the airflow, the heavier materials on the vibrating screen 110 are carried to the higher end of the screen and discharged through the heavy hopper 250, while the lighter materials are carried to the lower end of the screen 110 and discharged through the light hopper 260. This process achieves the separation of various minerals with different specific gravities. In addition, the mineral dust generated during this process is also sucked away by a dust removal device connected to the air outlet. This mineral processing machine is suitable for use in areas with scarce water resources and can also reduce environmental pollution.
