Description

Technical Field

[0001] This application relates to the field of vibrating screens, and more particularly to a material vibrating screen. Background Technology

[0002] A vibrating screen operates by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two forces results in a complex rotary vibration of the screen surface. Its vibration trajectory is a complex spatial curve. By changing the shape of the curve of the screen surface's motion trajectory and thus changing the motion trajectory of the material on the screen surface, the material screening effect is achieved.

[0003] In existing technologies, screen plates may wear out after prolonged use and need to be replaced in a timely manner. However, current screen plates are generally integrally molded, and when some parts of the screen plate are severely worn, the entire structure needs to be replaced, which is wasteful.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of difficulty in replacing the screen plate, this application provides a material vibrating screen.

[0006] The material vibrating screen provided in this application adopts the following technical solution:

[0007] A material vibrating screen includes fixed plates. A connecting frame is fixedly connected to one side of each of the two fixed plates. Several vibration springs are fixedly connected to both sides of the upper surface of the connecting frame. An mounting bracket is elastically slidably connected to the upper surface of the connecting frame through the vibration springs. A sliding groove is formed on both sides of the interior of the mounting bracket. A threaded rod is rotatably connected to both sides of the interior of the sliding groove. A slider is threadedly connected to one side of the outer wall of each threaded rod. A first bevel gear is fixedly connected to one side of each of the two threaded rods. A second bevel gear is rotatably connected to one side of each sliding groove corresponding to the first bevel gear. The second bevel gear and the two first bevel gears are tightly meshed.

[0008] Preferably, the outer surface of the mounting bracket is rotatably connected to two knobs via the second bevel gear, and the upper surface of the mounting bracket has openings on both sides, with a mounting block slidably connected to one side of each opening.

[0009] Preferably, the inner wall of the mounting bracket is provided with a sliding opening on the side corresponding to the opening, the outer wall of the slider is fixedly connected with an insert plate on the side corresponding to the sliding opening, and the outer wall of the mounting block is provided with a fixing hole on the side corresponding to the sliding opening.

[0010] Preferably, the upper surface of the mounting frame is provided with a material screen through a plurality of mounting blocks, and a vibration motor is fixedly connected to one side of the side surface of the fixing plate.

[0011] Preferably, each of the outer walls of the fixing plates has several mounting holes, and a collection box is provided on the opposite side of the two fixing plates.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The second bevel gear is rotated by turning the knobs on both sides in both directions. The second bevel gear meshes tightly with the first bevel gears on both sides. The first bevel gears are connected to the threaded rods, which in turn drive the threaded rods on both sides to rotate simultaneously. The slider is connected to the insert plate, so that the rotation of the threaded rods causes the sliders on both sides to move towards or away from each other, thereby fixing or unfixing the material screen, making it easy to install or disassemble. Compared with the existing technology, it is easier to assemble and disassemble as a whole, and does not require the use of professional tools by the staff, thus improving the overall work efficiency.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0020] This application discloses a material vibrating screen. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A vibrating screen for materials includes two fixed plates 1 with a connecting frame 5 fixedly connected to one side of each other. Several vibrating springs 6 are fixedly connected to both sides of the upper surface of the connecting frame 5. A mounting frame 4 is elastically and slidably connected to the upper surface of the connecting frame 5 via the vibrating springs 6. The mounting frame 4 is connected to the connecting frame 5 via the vibrating springs 6, and the outer wall of the mounting frame 4 does not contact the outer walls of the two fixed plates 1, allowing the mounting frame 4 to move up and down for easy material screening. Slide grooves 14 are provided on both sides of the interior of the mounting frame 4. Threaded rods 16 are rotatably connected to both sides of the interior of the slide grooves 14. The helix angle of the outer wall of the threaded rod 16 is set to 20 degrees. A slider 15 is threadedly connected to one side of the outer wall of the threaded rod 16. The size of the slider 15 matches the size of the slide groove 14, allowing the rotation of the threaded rod 16 to move the slider 15 along the inner wall of the slide groove 14. The threaded lifting angle of the threaded rod 16 is less than the equivalent friction angle of the helical pair formed by the slider 15 and the threaded rod 16, forming a self-locking mechanism to prevent movement due to external factors. A first bevel gear 13 is fixedly connected to the opposite side of each of the two threaded rods 16. A second bevel gear 17 is rotatably connected to the inside of the slide groove 14 on the side corresponding to the first bevel gear 13. The second bevel gear 17 and the two first bevel gears 13 are tightly meshed. Through the tight meshing between the two first bevel gears 13 and the second bevel gear 17, the rotation of the second bevel gear 17 drives the first bevel gears 13 on both sides to rotate simultaneously. Since the two first bevel gears 13 are connected to the threaded rod 16, they drive the threaded rods 16 on both sides to rotate simultaneously. This can drive the sliders 15 on both sides to move towards or away from each other along the inner wall of the slide groove 14, achieving the effect of facilitating the movement of the sliders 15 on both sides.

[0021] Reference Figure 2 , Figure 3 and Figure 4 The outer surface of the mounting bracket 4 is rotatably connected to two knobs 7 via the second bevel gear 17. The upper surface of the mounting bracket 4 has openings 10 on both sides. The inner side of each opening 10 is slidably connected to a mounting block 11. The knobs 7 are connected to the second bevel gear 17, so that rotating the knobs 7 drives the second bevel gear 17 to rotate, thereby controlling the rotation of the threaded rods 16 on both sides. The size of the opening 10 matches the size of the mounting block 11, so that the mounting block 11 can be inserted into the opening 10.

[0022] Reference Figure 2 , Figure 3 and Figure 4The inner wall of the mounting bracket 4 is provided with a sliding opening 19 on one side corresponding to the opening 10. The outer wall of the slider 15 is fixedly connected with an insert plate 18 on one side corresponding to the sliding opening 19. The outer wall of the mounting block 11 is provided with a fixing hole 12 on one side corresponding to the sliding opening 19. The slider 15 is connected to the insert plate 18, so that the rotation of the threaded rods 16 on both sides drives the sliders 15 on both sides to move towards each other or away from each other, and then drives the insert plate 18 to move towards each other or away from each other. By setting the size of the fixing hole 12, the sliding opening 19 and the insert plate 18 to be the same, the fixing hole 12 and the sliding opening 19 are aligned after the mounting block 11 is inserted into the opening 10. This drives the slider 15 to move to the position of the sliding opening 19, and drives the insert plate 18 to move out from the position of the sliding opening 19 and insert into the inside of the fixing hole 12, so that the mounting block 11 is fixed inside the opening 10, which achieves the effect of facilitating the fixing of the mounting block 11.

[0023] Reference Figure 1 and Figure 2 The upper surface of the mounting frame 4 is provided with a material sieve 9 by a number of mounting blocks 11. A vibration motor 3 is fixedly connected to one side of the side surface of the fixing plate 1. The vibration motor 3 is preferably a YZS-15-4 type. When the vibration motor 3 is started by a switch, the vibration motor 3 will drive a number of vibration springs 6 on the top of the connecting frame 5 to vibrate, which in turn drives the material sieve 9 to screen the material. The material sieve 9 is connected to the mounting blocks 11. After the mounting blocks 11 are fixed inside the opening 10, the material sieve 9 is installed in the mounting frame 4. By flipping the knobs 7 on both sides, the insert plates 18 on both sides are moved out from the inside of the fixing holes 12, and the material sieve 9 can be removed from the inner wall of the mounting frame 4, which achieves the effect of facilitating the installation and disassembly of the mounting frame 4.

[0024] Reference Figure 1 and Figure 2 The outer wall of the fixing plate 1 is provided with several mounting holes 8 on one side. The two fixing plates 1 are provided with a collection box 2 on the opposite side. The mounting holes 8 on the outer wall of the fixing plate 1 facilitate the installation of the fixing plate 1. By setting the collection box 2 at the bottom of the material screen 9, the material screened by the material screen 9 falls into the collection box 2 for collection.

[0025] The implementation principle of a material vibrating screen according to this application embodiment is as follows: When the material screen 9 wears out after working for a period of time, the second bevel gear 17 is rotated by reversing the knobs 7 on both sides. The second bevel gear 17 meshes tightly with the first bevel gears 13 on both sides. The first bevel gear 13 is connected to the threaded rod 16, which in turn drives the threaded rods 16 on both sides to rotate simultaneously. The slider 15 is connected to the insert plate 18, so that the rotation of the threaded rod 16 drives the sliders 15 on both sides to move towards each other, thereby moving the insert plate 18 out of the fixed hole 12, through the slide 19 and into the slide groove 14, thereby releasing the fixation of the material screen 9. Then the material screen 9 is removed and replaced with a new material screen 9. By aligning several mounting blocks 11 on the outer wall of the material screen 9 with the opening 10, the insert plate 18 is driven into the fixed hole 12 by rotating the knob 7 in the forward direction, and the material screen 9 is installed and fixed.
