Description
Technical Field
[0001] The present invention relates to the technical field of vibration exciters, in particular to a side plate mounted box-type vibration exciter. Background Art
[0002] Today, vibrating screens have become indispensable equipment in numerous industries, including mining, aggregate processing, coal production, ceramic raw material processing, silica sand production and processing, and various metal mine tailings treatment. A power source is essential for vibrating screen operation. These sources typically include box-type vibrators, disc-type vibrators, and vibration motors, with box-type vibrators providing the most stable power source. Traditional box-type vibrators primarily consist of two sets of eccentric devices placed parallel to each other within the vibrator body. These two sets of eccentric devices mesh with each other via two helical gears mounted on the main shaft. Connected to an external power source via a connecting end cap, they achieve synchronous, counter-rotating circular motion driven by the power source, providing excitation force for the equipment. Each set of eccentric devices has two eccentric weights of equal mass mounted on either end of the main shaft. Each eccentric weight has five holes of equal size, each accommodating five counterweights of equal mass. The holes on the circumferential surface of the counterweights are aligned with the holes on the curved surface of the eccentrics, and spring pins are installed to secure the weights, preventing them from falling during operation. Adjusting the number and position of the five sets of counterweights allows for eight different levels of excitation force.
[0003] Chinese patent application number CN2024216167136 discloses a box-type vibrator, which relates to the field of vibrator technology and aims to solve the problem that existing eccentric blocks cannot change the weight of the eccentric block according to the actual working environment, thereby adjusting the magnitude of the exciting force. The box includes a box body and a box cover. The box body is a shell with a transparent top surface and a box cover. The box body is rotatably connected to a rotating shaft through a bearing seat, and the rotating shaft protrudes from the left and right sides of the box body. The protruding end of the rotating shaft is connected to a split eccentric block via a retaining ring and a sealing ring. The eccentric block includes side plates and inner plates. The side plates are provided in two groups, and several groups of inner plates are provided between the two groups of side plates. The inner plates are provided with a clamping hole for mounting a counterweight block. The eccentric block uses side plates and inner plates. The number of inner plates between the two groups of side plates can be increased according to the working conditions to adjust the weight of the eccentric block. The weight of the eccentric block can also be increased by clamping a counterweight block into the clamping hole of the inner plate to adapt to production needs.
[0004] The Chinese patent application number is CN2023229308392. This technical solution discloses an amplitude-adjustable vibrator for a vibrating screen, comprising a pendulum block, a strip-shaped hole is provided in the middle of the side of the pendulum block, a connecting plate is provided inside the strip-shaped hole for sliding up and down, the connecting plate is movably mounted on the rotating shaft of the vibrator, two adjusting bolts are rotatably provided on the pendulum block, and adjusting screw holes are provided at the positions corresponding to the adjusting bolts, and the adjusting bolts are threadedly connected to the adjusting screw holes. The amplitude-adjustable vibrator for a vibrating screen can adjust the relative position of the entire pendulum block and the rotating shaft of the vibrator by rotating the adjusting bolts, thereby achieving precise adjustment of the amplitude of the vibrator and eliminating the process of repeated disassembly and replacement of counterweights in the traditional method. The adjustment speed is fast, work efficiency can be improved, and the operation is simple and easy to use.
[0005] The above solution still has the following problems during use:
[0006] 1. Currently, all box-type vibrators on the market are base-mounted. The vibrating screen requires a large main beam to install the base-type box-type vibrator. The main beam is difficult to manufacture and has high costs. Improper use on site in the later stage can easily cause the main beam to crack, resulting in high maintenance costs for the main beam.
[0007] 2. The eccentric block adjustment of the traditional box-type vibrator requires adding and removing counterweight blocks. After the equipment is installed, the eccentric blocks overlap with each other, making it difficult to install and remove the counterweight blocks on the internal eccentric blocks. The outer eccentric blocks need to be removed before adjustment can be made. The labor and cost required for each debugging are high.
[0008] 3. The vibrators on the market will generate a lot of heat during continuous operation. This heat cannot be dissipated, which will increase the temperature of the vibrator and affect the efficiency of the vibration equipment. Summary of the Invention

[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0044] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4, considering that the box-type vibrators on the market are all base-mounted, the vibrating screen needs to provide a large main beam to install the base-type box-type vibrator. The main beam is difficult to make and the cost is high. Improper on-site use in the later stage can easily cause the main beam to crack, resulting in high maintenance costs for the main beam. At the same time, the eccentric block adjustment of the traditional box-type vibrator requires adding and removing counterweight blocks. After the equipment is installed, the positions of the eccentric blocks overlap with each other, making it difficult to install and remove the counterweight blocks on the internal eccentric blocks. The outer eccentric blocks need to be removed before adjustment. The labor and cost required for each debugging are high. A side panel mounted box-type vibrator includes an exciter shell 1, and the exciter shell 1 is rotatably connected to two main shafts 2 distributed on the left and right. The front and rear ends of the main shaft 2 are respectively provided with a main eccentric block 21 and a secondary eccentric block 22. A rotating part is provided at the connection between the main shaft 2 and the exciter housing 1. The box-type vibrator is directly installed on the side panel of existing equipment such as existing vibrating screens, and the exciting force is directly transmitted to the equipment. The main beam on the equipment for installing the old box-type vibrator is eliminated, which directly reduces the equipment manufacturing cost. The exciting force of the box-type vibrator can act more directly on the equipment body, and the equipment operation effect is better. The main eccentric block 21 and the secondary eccentric block 22 are combined to achieve the adjustment of different exciting forces by changing the angle between the main eccentric block 21 and the secondary eccentric block 22, which reduces the difficulty of adjusting the exciting force and saves the later use and maintenance costs.
[0045] See also Figure 4 、 Figure 8 、 Figure 9 and Figure 10, considering that when the main shaft 2 rotates and the vibrating screen is driven to work, dust will be generated during screening, causing the dust to float. If the dust enters the interior of the rotating part, it will affect the use of the rotating part. The rotating part includes a retaining frame 6, on which rolling bodies 64 and rollers 65 are installed, so that the rolling bodies 64 and rollers 65 are evenly distributed between the outer ring 3 and the inner ring 4, avoiding contact and collision between the rolling bodies 64 and the rollers 65, and ensuring that each rolling body 64 and roller 65 can roll normally on its respective track, thereby improving the operation accuracy and stability of the rotating part. During the operation of the rotating part, the retaining frame 6 can withstand a certain load and transfer the load evenly to the rolling bodies. When the rotating part is subjected to radial or axial load, the retaining frame 6 distributes the load to each rolling element 64 and roller 65, so that the rolling element 64 and roller 65 can share the load, avoiding damage of a single rolling element 64 and roller 65 due to excessive load, thereby improving the overall load-bearing capacity of the rotating part. The inner side of the retaining frame 6 is connected to the inner ring 4, and the outer side of the retaining frame 6 is provided with an outer ring 3. The left and right sides of the retaining frame 6 are respectively provided with sealing rings 5, and the sealing rings 5 connect the outer ring 3 and the inner ring 4. The sealing rings 5 can form a sealed environment inside the rotating part, effectively preventing grease from leaking outward, so that the grease is kept inside the rotating part, continuously providing good lubrication for the rotating part, and extending the service life of the rotating part. At the same time, external dust, moisture, impurities, etc. entering the rotating part will aggravate the wear of the rotating part and reduce the accuracy and performance of the rotating part. The retaining frame 6 can act as a barrier to prevent these impurities from entering the interior of the rotating part, protecting the outer ring 3, inner ring 4, retaining frame 6, rolling element 64 and roller 65 and other components of the rotating part from being contaminated. A heat sink 7 is provided on the sealing ring 5 located on the outside of the exciter housing 1, and a clamping member 8 is connected to the heat sink 7. The heat sink 7 is connected to the main shaft 2 through the clamping member 8. The heat sink 7 scrapes the surface of the sealing ring 5 and generates wind force at the same time, which is conducive to scraping off the dust accumulated on the surface of the sealing ring 5. At the same time, the wind generated by the heat sink 7 blows away the scraped dust.
[0046] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7, considering that the device works with the existing vibrating screen when in use, dust will be generated during the operation of the vibrating screen, and the rotating parts need to be sealed. At the same time, when the rotating parts rotate for a long time, noise will be generated. The left and right ends of the outer ring 3 are respectively provided with a card slot 31, and the inner and outer sides of the card slot 31 are provided with a semicircular sealing ring 32. The opposite sides of the two card slots 31 are respectively provided with an L-shaped clamping ring 33. The card slot 31 is used to clamp the sealing ring 5, and the sealing ring 5 is clamped therein to complete the fixation of the sealing ring 5. The semicircular sealing ring 32 arranged inside the card slot 31 is offset against the sealing ring 5 to form a seal to prevent external pollutants from entering the interior of the rotating part. At the same time, a clamping ring 33 is provided inside the card slot 31. The snap ring 33 is snapped with the sealing ring 5. After the sealing ring 5 is fixed, the snap ring 33 can effectively prevent the sealing ring 5 from being thrown out when the rotating part is working. At the same time, the snap ring 33 also forms a seal with the sealing ring 5 again to enhance the sealing effect. The opposite sides of the two snap grooves 31 are respectively provided with an elliptical snap groove 34. The inner ring of the snap groove 31 is chamfered. By providing the snap groove 34, the sealing ring 5 can be fixed when installing the sealing ring 5, and the firmness of the sealing ring 5 is enhanced to prevent the sealing ring 5 from being separated from the outer ring 3 and the inner ring 4. The left and right ends of the inner ring 4 are respectively provided with a convex groove 41, and the opposite sides of the two convex grooves 41 are respectively provided with a sealing convex ring 42. The inner ring of the convex groove 41 The side is chamfered, and an isolation raceway 43 is provided in the center of the inner ring 4. By chamfering the inner side of the convex groove 41, the sealing ring 5 can be quickly snapped into the convex groove 41, which is convenient for connection with the inner ring 4. At the same time, a sealing convex ring 42 is provided inside the convex groove 41. After the sealing ring 5 is snapped into the convex groove 41, the sealing ring 5 will be against the sealing convex ring 42 to form a seal again. The sealing ring 5 is annular and hollow inside. A plurality of reinforcing ribs 59 are provided inside the sealing ring 5. The reinforcing ribs 59 separate the cavity of the sealing ring 5. Setting the interior of the sealing ring 5 to be hollow is beneficial to reducing the noise generated by the rotation of the rotating part. At the same time, reinforcing ribs 59 are provided inside the sealing ring 5 to ensure the overall In order to improve the rigidity, the outer wall of the sealing ring 5 is provided with a semicircular sealing groove 51 corresponding to the semicircular sealing ring 32, and a clamping protrusion 53 corresponding to the clamping groove 34 is provided on the left side of the semicircular sealing groove 51. A sealing baffle 54 is provided on the left side of the clamping protrusion 53, and a clamping ring 52 corresponding to the clamping ring 33 is provided on the right side of the semicircular sealing groove 51. The clamping protrusion 53 cooperates with the sealing baffle 54, and the clamping protrusion 53 and the sealing baffle 54 clamp the edge of the outer ring 3 to form a seal. At the same time, when the heat sink 7 is scraped and dusted, the sealing baffle 54 will also prevent dust from entering the interior of the rotating part to prevent dust from contaminating the components inside the rotating part. The right side of the semicircular sealing groove 51 is provided with a clamping ring 52 corresponding to the clamping ring 33.The inner wall of the sealing ring 5 is provided with a sealing ring groove 57 corresponding to the sealing convex ring 42. The left end of the sealing ring groove 57 is provided with a clamping plate 58 corresponding to the inner ring 4. The left end of the sealing ring 5 is provided with a guide ring 55. The guide ring 55 is oval and tilted upward. By providing the guide ring 55, when removing the sealing ring 5, the sealing ring 5 can be removed from the outer ring 3 and the inner ring 4 by pulling the guide ring 55. At the same time, the guide ring 55 plays a certain guiding role in the rotation of the heat sink 7, making the heat sink 7 rotate more smoothly. The right end of the sealing ring 5 is provided with a fixing groove 56. The fixing groove 56 is used to abut the edge of the retaining frame 6. By abutting the edge of the retaining frame 6 with the fixing groove 56, the sealing ring 5 clamps the retaining frame 6 to prevent the retaining frame 6 from shaking.
[0047] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7, considering that when the main shaft 2 rotates, due to the action of the main eccentric mass 21 and the secondary eccentric mass 22, the main shaft 2 will press the inner ring 4 and the rolling elements 64 and the rollers 65 against the outer ring 3. At the same time, since there is a gap between the two rollers of the existing bearing, when it moves to a certain angle, the force will act in the gap, causing damage to the bearing. The retainer 6 includes two outer rings 61 and an inner ring 62. The two outer rings 61 are located on both sides of the two inner rings 62. The diameter of the outer ring 61 is larger than the diameter of the inner ring 62. Spacer rods are connected between the outer ring 61 and the inner ring 62, and between the inner ring 62 and the inner ring 62 respectively. The spacer rod between the outer ring 61 and the inner ring 62 is staggered with the spacer rod between the inner ring 62 and the inner ring 62. When the rolling elements 64 and the rollers 65 are installed, the rolling elements 64 and the rollers 65 are also staggered. During rotation, the load is reasonably carried and transmitted, making the rotating part more stable and reliable during operation. It can adapt to different working conditions, such as high speed, heavy load, high temperature, etc., reduce the probability of bearing failure, improve the operating reliability of the equipment, reduce maintenance costs and downtime, and form a placement frame between the outer ring 61 and the inner ring 62 through a spacer rod. The opposite sides of the outer ring 61 and the inner ring 62, and the opposite sides of the inner ring 62 and the inner ring 62 are respectively fixed with limit blocks 63. The limit blocks 63 are located in the placement frame. The placement frame between the outer ring 61 and the inner ring 62 is provided with a roller 65, and the placement frame between the two inner rings 62 is provided with a rolling body 64. The roller Circular grooves are provided on the left and right ends of the rollers 65 and the rolling elements 64, respectively. The grooves correspond to the stoppers 63 on the outer ring 61 and inner ring 62, respectively. The stoppers 63 connect the rolling elements 64 and rollers 65, restricting their positions and maintaining an appropriate gap between them. This reduces friction and wear between the rolling elements 64 and rollers 65, as well as between the rolling elements 64 and rollers 65 and the outer ring 3 and inner ring 4, further reducing frictional power consumption and improving the efficiency and service life of the rotating parts. The rollers 65 are truncated cone-shaped, while the rolling elements 64 are hourglass-shaped. The rolling elements 64 and rollers 65 are staggered.
[0048] See also Figure 4 and Figure 10, considering that dust will accumulate on the rotating parts after floating, it is necessary to scrape the dust from the rotating parts. At the same time, after the rotating parts work for a long time, heat will be generated. At this time, the rotating parts also need to be cooled. The outer wall of the heat sink 7 is fixed with a plurality of blades 71 along its circumference. The blades 71 are respectively provided with cleaning notches 711. The cleaning notches 711 are correspondingly connected to the guide ring 55 on the sealing ring 5. The heat sink 7 is close to the sealing ring 5 and a plurality of mounting grooves 72 are provided along its circumference. The mounting grooves 72 are respectively slidably connected with clamping blocks 73. The clamping blocks 73 can be fitted with the main shaft 2. The clamping member 8 is threadedly connected to the heat sink 7. The clamping member 8 is provided with an oblique angle 81 at one end close to the heat sink 7. The other end of the part 8 is provided with a hexagonal groove for connecting a wrench. When installing the heat sink 7, the heat sink 7 is sleeved on the main shaft 2 so that the cleaning notch 711 on the blade 71 is clamped on the guide ring 55. After the clamping is completed, use the existing wrench to connect the clamping part 8 to the heat sink 7. The bevel 81 on the clamping part 8 will abut against the clamping block 73. Due to the effect of the bevel 81, the clamping block 73 will slide toward the main shaft 2. As the clamping part 8 and the heat sink 7 are gradually connected, the clamping block 73 will gradually clamp the main shaft 2. When the main shaft 2 rotates, the lower end of the blade 71 fits against the sealing ring 5 to scrape off the dust on the sealing ring 5. At the same time, the rotation of the blade 71 will generate wind to blow away the scraped dust, and the wind generated will cool the rotating parts.
[0049] The present invention is installed on the existing equipment vibrating screen for use, and is used in conjunction with the existing power source to drive the main shaft 2 to rotate. The device is fixed to the side panel of the equipment to be installed, and the two sets of main shafts 2 and gears 23 are respectively installed inside the exciter housing 1. The main eccentric block 21 and the secondary eccentric block 22 are installed at both ends of the main shaft of the main shaft 2, and the angle between the main eccentric block 21 and the secondary eccentric block 22 is adjusted to a suitable angle according to the requirements. The angles between the four groups 210 and the secondary eccentric block 22 must be the same, and then the end cover is installed on the secondary eccentric block 22, and the main eccentric block 21 and the secondary eccentric block 22 are fixed to the main shaft 2 as a whole. The external motor is connected to the end cover through a coupling to transmit the motor torque to the main shaft 2 The main shaft 2 drives the gear 23 inside the exciter housing 1 to rotate, and the two sets of gears 23 rotate synchronously in opposite directions to drive the two sets of main eccentric blocks 21 and auxiliary eccentric blocks 22 to rotate in opposite directions. The two sets of main eccentric blocks 21 and auxiliary eccentric blocks 22 rotate to generate a set of reciprocating linear vibration forces to drive the device to perform reciprocating linear motion. Different customers can achieve different exciting force requirements by adjusting the angle between the main eccentric block 21 and the auxiliary eccentric block 22 according to the on-site conditions. When the main shaft 2 rotates, the lower end of the blade 71 fits against the sealing ring 5 to scrape off the dust on the sealing ring 5. At the same time, the rotation of the blade 71 will generate wind to blow away the scraped dust, and the generated wind will cool the rotating parts.
[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
