[0002] Vibrating screen is a screening equipment widely used in the industrial field to separate and grade materials of different particle sizes. Its working principle is to generate vibration through devices such as vibration motors or eccentric shafts, so that the materials on the screen surface are ejected and bounced, and smaller particles fall through the screen holes, while larger particles move along the screen surface to the discharge port.

[0003] After feeding, the existing vibrating screen usually accumulates on the surface of the screen and needs to be spread manually. However, there is a certain error in manual spreading, which will still cause uneven distribution of materials on the surface of the screen, resulting in unbalanced vibration, which in turn causes the vibrating screen to shake and increase noise. Therefore, it is necessary to provide a vibrating screen that can spread materials evenly to maintain the stability and low noise of the vibrating screen. Utility Model Content

[0039] See also Figure 1-7 As shown, this embodiment is a stable low-noise vibrating screen, comprising:

[0040] Screening component, the screening component includes a screening box 101, a receiving frame 102 and a screen 103;

[0041] The uniform flattening assembly includes a rectangular bar 201, a mounting frame 202, a bidirectional rotating motor 203, a threaded rod 204, an adjustment slot 205, a flattening plate 206, a first threaded hole 207 and a butterfly screw 208;

[0042] A receiving frame 102 is movably installed in the middle of the screening box 101, a screen 103 is fixedly installed in the middle of the receiving frame 102, a rectangular bar 201 is movably connected to the top of the receiving frame 102, a mounting frame 202 is fixedly connected to the rear of the screening box 101, a bidirectional rotating motor 203 is fixedly installed in the front of the mounting frame 202, a threaded rod 204 is connected to the output end of the bidirectional rotating motor 203, the threaded rod 204 is movably inserted into the rectangular bar 201, an adjusting slot 205 is provided on the rectangular bar 201, a spreading plate 206 is movably inserted in the middle of the adjusting slot 205, a first threaded hole 207 is provided in the front of the adjusting slot 205, a butterfly screw 208 is inserted in the middle of the first threaded hole 207;

[0043] The screen 103 is used to screen and filter the material, and the middle part of the screening box 101 is used to load the screened material. The installation frame 202 provides a carrier for the installation of the bidirectional rotating motor 203, and the bidirectional rotating motor 203 provides kinetic energy for the rotation of the threaded rod 204. The adjustment slot 205 provides a guarantee for the vertical height adjustment of the spreading plate 206. The spreading plate 206 moves back and forth to achieve uniform paving of the material. The rotation of the butterfly screw 208 in the first threaded hole 207 can achieve the fixation of the spreading plate 206 after it moves up and down.

[0044] The screening assembly also includes a base 104, a receiving rod 105, a rectangular cylinder 106 and a buffer spring 107;

[0045] A base 104 is provided at the bottom of the screening box 101, receiving rods 105 are fixedly installed at the four corners of the bottom of the screening box 101, rectangular cylinders 106 are fixedly installed at the four corners of the top of the base 104, the receiving rods 105 are movably inserted into the rectangular cylinders 106, and a buffer spring 107 is installed outside the receiving rods 105;

[0046] The base 104 is used to play a role of placing it firmly on the ground. The receiving rod 105 and the rectangular cylinder 106 are used in conjunction with each other to achieve buffering when the screening box 101 moves up and down, and the buffer spring 107 can further play a buffering role;

[0047] The screening assembly also includes a vibration motor 108;

[0048] A vibration motor 108 is fixedly installed at the bottom of the screening box 101. There are two vibration motors 108 in total, and they are installed at a 45-degree inclination. At the same time, the two vibration motors 108 rotate in opposite directions.

[0049] The two counter-rotating vibration motors 108 are installed at an angle, which can generate a force to maintain the vertical direction, thereby ensuring that the screening box 101 moves in the vertical direction, thereby ensuring the screening effect;

[0050] The evenly flattening assembly further includes a second threaded hole 209, a slide groove 2010, a slider 2011 and a limit bar 2012;

[0051] A second threaded hole 209 is formed at the left end of the rectangular bar 201, and the threaded rod 204 is movably inserted into the second threaded hole 209. Slide grooves 2010 are formed at both sides of the receiving frame 102. The bottoms of both sides of the rectangular bar 201 are fixedly connected to sliders 2011, and the sliders 2011 are movably connected to the slide grooves 2010. The top of the spreading plate 206 is fixedly connected to the limit bar 2012.

[0052] The second threaded hole 209 is provided to ensure the insertion of the threaded rod 204. The sliding of the slider 2011 in the slide groove 2010 can assist the sliding of the rectangular bar 201. The limiting bar 2012 is provided to prevent the spreading plate 206 from sliding into the adjustment groove 205 and falling off.

[0053] Working principle: first, pour the material on the top of the screen 103, and estimate the height of the material on the top of the screen 103 after evenly spreading according to the volume of the material, and then move the spreading plate 206 up and down along the adjustment slot 205. When the length of the rectangular bar 201 protruding from the bottom of the spreading plate 206 is adjusted appropriately, tighten the butterfly screw 208 at the first threaded hole 207, and then turn on the bidirectional rotary motor 203 to drive the threaded rod 204 to rotate in the second threaded hole 209. With the cooperation of the slider 2011 and the slide slot 2010, the rectangular bar 201 drives the spreading plate 206 to move back and forth above the material until the material is evenly spread, and then turn on the two vibration motors 108 to drive the screening box 101 to vibrate up and down, thereby realizing the screening of the material. At this time, the receiving rod 105 moves up and down at the rectangular cylinder 106, and the buffer spring 107 is compressed and restored to reciprocate.

[0054] This step can ensure that the material is evenly distributed on the screen surface, thereby avoiding vibration imbalance, and further avoiding shaking of the vibrating screen and preventing the increase of noise; and the height of the spreading plate can be adjusted according to the volume of different materials added, thereby improving applicability.

One end of a disassembly spring 303 is fixedly connected to the receiving frame 102 inside the mounting holes 302, and the other end of the disassembly spring 303 is fixedly connected to a buckle head 304. The buckle head 304 is movably inserted through the through hole 301, and the front end of the buckle head 304 is arc-shaped.

[0059] The stable disassembly and assembly assembly also includes a rubber ring 305;

[0060] The outer ring of the buckle head 304 is fixedly mounted with a rubber ring 305;

[0061] The provision of the rubber ring 305 can prevent the buckle head 304 from directly contacting the through hole 301 on the screening box 101 .

[0062] When the clamping head 304 and the rubber ring 305 are moved to the through hole 301, the mounting frame 102 and the screen 103 can be disassembled.

[0063] This step can achieve rapid disassembly of the receiving frame and the screen, and no additional tools are required in the process, thereby improving the convenience of disassembly and assembly; and avoiding direct contact between the snap head and the through hole of the screen box during vibration, further reducing the metal collision noise generated by vibration.
