DETAILED DESCRIPTION

[0017] Please refer to Figures 1-4The present invention provides the following technical solution: including a bottom box 1, a support rod 11 and a spring 12, a support plate 2 is installed on the spring 12, a lower support groove 21 is opened on the support plate 2, a lower filter screen 22 is engaged with the inner wall of the lower support groove 21, a discharge box 23 is installed at the bottom of the support plate 2, a frame plate 3 is fixedly connected to the top of the support plate 2, an upper filter box 31 is provided between the two frame plates 3, the upper filter box 31 is connected to the upper filter box 31 through a central rod 311, a crossbar 32 is slidably connected between the two frame plates 3, two frame rods 33 are hinged to one side of the crossbar 32, an installation plate 34 is fixedly connected to both ends of the upper filter box 31, a sliding rod 35 is fixedly connected to the installation plate 34, the sliding rod 35 is slidably connected to the frame rod 33, an upper support groove 36 is opened at the bottom of the upper filter box 31, an upper filter screen 37 is engaged with the inner wall of the upper support groove 36.

[0018] In this implementation scheme: the bottom box 1 serves as the carrier of the supporting device. A spring 12 is mounted on a support rod 11 fixedly connected to the bottom box 1, allowing the spring 12 to support the support plate 2. A vibration motor is mounted on the support plate 2, enabling the device to generate centrifugal force when the motor rotates by eccentric blocks mounted on the shafts at both ends of the motor. This centrifugal force causes the sand screening machine to vibrate, allowing the device to screen various metal powders or particles used in the pressurizer production, selecting the required particle size range. During use, the two support plates 3 fixedly connected to the support plate 2 are positioned above the device. The upper filter box 31, installed between the frame plates 3, is connected to the frame plates 3 via a central rod 311. The middle section of the upper filter box 31 is hinged to one side of the frame plate 3, allowing the angle of the upper filter box 31 between the frame plates 3 to be adjusted. This allows the particle material to be directly fed into the upper filter box 31 during metal particle screening. The upper support groove 36 at the bottom of the upper filter box 31 allows for the installation of the upper filter screen 37. Different pore sizes of the upper filter screen 37 can be selected for the first stage of metal sand and gravel screening, ensuring that larger particles are blocked on the upper filter screen 37 while other particles can pass through. 37 falls downwards, landing on the lower filter screen 22 that engages with the inner wall of the lower support groove 21 for further screening. This allows particles smaller than the required metal particle size to fall below the lower filter screen 22, while the required metal particles are quickly screened onto the lower filter screen 22 for storage. During screening, to prevent metal particles from accumulating and clogging due to vibration, when there are many metal particles on the upper filter box 31, the angle of the upper filter box 31 can be changed. This allows the metal particles to move downwards on the inclined surface of the upper filter screen 37 while being vibrated, increasing screening efficiency. At this time, the crossbar 32 can slide on... Between the support plates 3, the crossbar 32 is slidably connected to the slide bar 35 installed on the mounting plate 34 via the support rod 33. When the height of the crossbar 32 is adjusted, the two crossbars 32 will have a height difference, which will cause the connection between the support rod 33 and the mounting plate 34 to change the angle of the upper filter box 31. This allows the device to continuously adjust the angle of the upper filter box 31, making it adjustable in the left and right directions. When the metal particles roll on the upper filter screen 37, the final flow direction can be adjusted to avoid a single tilt direction and accumulation on one end of the upper filter screen 37, which would affect the overall screening of metal particles and the screening efficiency.

[0019] The support rod 11 and spring 12 are offset from the discharge box 23, and the lower filter screen 22 corresponds to the upper filter screen 37. The offset of the support rod 11 and spring 12 from the discharge box 23 enables the discharge box 23 to discharge smaller particles in a concentrated manner. After the smaller particles are discharged, the larger particles on the upper filter screen 37 are removed to facilitate further processing.

[0020] A hinge plate 331 is fixedly connected at the connection between the crossbar 32 and the frame rod 33. One end of the frame rod 33 is hinged to the two hinge plates 331 through a hinge rod 332. The hinge plate 331 fixedly connected at the connection between the crossbar 32 and the frame rod 33 can install one end of the frame rod 33. The frame rod 33 is hinged between the hinge plates 331 through the hinge rod 332. When the crossbar 32 moves up and down, the frame rod 33 can change its angle, and the length between the frame rod 33 and the mounting plate 34 can be extended or retracted, thereby adjusting the support height at both ends of the upper filter box 31.

[0021] A connecting plate 4 is fixedly connected between the frame plates 3. A drive motor 41 is installed on the connecting plate 4. A threaded rod 42 is fixedly connected to the drive end of the drive motor 41. A fixed rod 43 is fixedly connected between the frame plates 3. One end of the threaded rod 42 is rotatably connected to the fixed rod 43. The threaded rod 42 is threadedly connected to the crossbar 32. The connecting plate 4 fixedly connected between the frame plates 3 can install the drive motor 41, so that the drive motor 41 can drive the threaded rod 42. The threaded rod 42 is threadedly connected to the crossbar 32. The bottom of the threaded rod 42 is rotatably supported on the fixed rod 43, so that when the threaded rod 42 rotates, it can adjust the crossbar 32 up and down, thereby adjusting the height of the crossbar 32 relative to both ends of the upper filter box 31, so that the metal particles roll left and right during screening, ensuring that the metal particles are screened completely and maintaining speed.

[0022] A limiting block 321 is fixedly connected at the connection between the crossbar 32 and the frame plate 3. The frame plate 3 has a sliding groove 44 that matches the limiting block 321. The limiting block 321 fixedly connected at the connection between the crossbar 32 and the frame plate 3 is used to limit the crossbar 32 within the sliding groove 44, ensuring that the crossbar 32 slides horizontally between the frame plates 3.

[0023] A limiting rod 45 is fixedly connected to the inner wall of the slide 44, and a limiting hole 322 matching the limiting rod 45 is provided on the limiting block 321. The limiting rod 45 fixedly connected to the inner wall of the slide 44 can pass through the limiting hole 322 on the limiting block 321 to ensure that the limiting block 321 is limited to the inner wall of the slide 44, thereby ensuring that the horizontal bar 32 can move horizontally up and down.

[0024] The working principle and usage process of this utility model are as follows: Metal particle raw materials are fed into the upper filter box 31, which is hinged between the frame plates 3. Larger particles are blocked on the upper filter screen 37, while the remaining particles can pass through the upper filter screen 37 and fall downwards. Particles smaller than the required metal particle size fall below the lower filter screen 22, and the required metal particles are quickly screened onto the lower filter screen 22 for storage. During the screening operation, the crossbar 32 slides between the frame plates 3, and the crossbar 32 is connected to the mounting plate 3 via the frame rod 33. The sliding rod 35 installed on the 4 is slidably connected, and the frame rod 33 is slidably connected to the sliding rod 35. When the height of the crossbar 32 is adjusted, the two crossbars 32 will have a height difference. This will cause the connection between the frame rod 33 and the mounting plate 34 to change the angle of the upper filter box 31. This allows the device to continuously adjust the angle of the upper filter box 31, making it adjustable in the left and right directions. When the metal particles roll on the upper filter screen 37, the final flow direction can be adjusted to avoid a single tilt direction and accumulation on one end of the upper filter screen 37, which would affect the overall screening of metal particles and the screening efficiency.
