Description

Technical Field

[0001] The present invention relates to the technical field of exciters, and particularly to a side plate-mounted box-type exciter. Background Art

[0002] In today's society, vibrating screens have become indispensable equipment in many industries such as mining, aggregate processing, coal production, ceramic raw material processing, silica sand production and processing, and the treatment of various metal mine tailings. An essential component for the operation of a vibrating screen is a power source that generates operating power for the equipment. The power source is generally a box-type exciter, a disk-type exciter, a vibrating motor, etc. Among them, the box-type exciter is the most stable power source. The traditional box-type exciter mainly consists of two sets of eccentric devices placed in parallel inside the exciter body. The two sets of eccentric devices are meshed with each other through two helical gears installed on the main shaft, and are connected to an external power source through a connecting end cover. Under the drive of the power source, they perform reverse synchronous circular motion to provide excitation force for the equipment; at both ends of the main shaft of each set of eccentric devices, two eccentric blocks of the same mass are installed. Each eccentric block is provided with 5 through holes of the same size, and 5 counterweight blocks of the same mass can be installed in the through holes. After the through holes on the circumferential surface of the counterweight block are aligned with the hole positions on the arc surface of the eccentric block, spring pins are installed to fix the counterweight block so that the counterweight block does not fall off during the operation of the box-type exciter. And by adjusting the number and position of 5 groups of counterweight blocks, 8 different sizes of excitation force can be adjusted.

[0003] Chinese Patent with the patent application number CN2024216167136 discloses a box-type exciter, which relates to the technical field of exciters and aims to solve the problem that the existing eccentric blocks cannot change the weight of the eccentric blocks according to the actual working conditions to adjust the magnitude of the excitation force; it includes a box body and a box cover. The box body is a shell with a transparent top surface, and a box cover is provided on the box body. 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; a split-type eccentric block is connected to the protruding ends of the rotating shaft through a retaining ring and a sealing ring; the eccentric block includes side plates and inner plates. There are two groups of side plates, and several groups of inner plates are provided between the two groups of side plates. The inner plates are provided with clamping holes for installing counterweight blocks; the eccentric block adopts side plates and inner plates, and 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, or the weight of the eccentric block can be increased by clamping counterweight blocks in the clamping holes of the inner plates to adapt to the production requirements.

[0004] A Chinese patent with the patent application number CN2023229308392 discloses a vibrator for a vibrating screen with adjustable amplitude, which includes a pendulum block. A strip-shaped hole is formed in the middle of the side surface of the pendulum block. A connecting plate is slidably arranged up and down inside the strip-shaped hole. The connecting plate is movably installed on the rotating shaft of the vibrator. Two adjusting bolts are rotatably arranged on the pendulum block. Adjusting screw holes are formed at the positions of the connecting plate corresponding to the adjusting bolts, and the adjusting bolts are threadedly connected with the adjusting screw holes. This vibrator for a vibrating screen with adjustable amplitude can adjust the relative position of the entire pendulum block and the rotating shaft of the vibrator by rotating the adjusting bolts, can accurately adjust the amplitude of the vibrator, and eliminates the process of repeatedly disassembling, installing and replacing counterweight blocks in the traditional method. The adjustment speed is fast, the work efficiency can be improved, the operation is simple, and it is convenient to use.

[0005] The following problems will still occur during the use of the above solution: 1. All the box-type vibrators on the market at present are base-mounted. The vibrating screen needs to provide a large main beam to install the base-mounted box-type vibrator. The production of the main beam is difficult and costly. If it is used improperly on site later, it is easy to cause the main beam to crack, resulting in high maintenance costs of the main beam.

[0006] 2. The adjustment of the eccentric blocks of the traditional box-type vibrator requires adding and removing counterweight blocks. After the equipment is installed, due to the overlapping positions of the eccentric blocks, it is difficult to install and remove the counterweight blocks on the internal eccentric blocks. It is necessary to remove the outer eccentric blocks before adjustment. The labor and cost required for each debugging are high.

[0007] 3. A large amount of heat will be generated during the continuous operation of the vibrators on the market. If these heats cannot be dissipated, the temperature of the vibrator will rise, affecting the use efficiency of the vibrating equipment. Summary of the Invention

[0023] The following further describes the embodiments of the present invention in detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, considering that all the existing box-type exciters on the market are base-mounted, the vibrating screen needs to provide a large main beam to install the base-mounted box-type exciter. The production of the main beam is difficult and costly. Improper on-site use in the later stage is likely to cause the main beam to crack, resulting in high maintenance costs for the main beam. At the same time, the adjustment of the eccentric blocks of the traditional box-type exciter requires adding and removing counterweights. After the equipment is installed, due to the overlapping positions of the eccentric blocks, it is difficult to install and remove the counterweights on the internal eccentric blocks. It is necessary to remove the outer eccentric blocks before adjustment, and the labor and cost required for each debugging are high. A side plate-mounted box-type exciter includes an exciter housing 1. Two main shafts 2 distributed left and right are rotatably connected to the exciter housing 1. Main eccentric blocks 21 and sub-eccentric blocks 22 are respectively arranged at the front and rear ends of the main shaft 2. A rotating part is arranged at the connection between the main shaft 2 and the exciter housing 1. This box-type exciter is directly installed on the side plates of existing equipment such as existing vibrating screens, and the exciting force is directly transmitted to the equipment, eliminating the main beam for installing the old box-type exciter on the equipment, directly reducing the equipment production cost. The exciting force of the box-type exciter can act more directly on the equipment body, and the equipment operation effect is better. By adopting the combination of the main eccentric block 21 and the sub-eccentric block 22, different exciting forces are adjusted by changing the included angle between the main eccentric block 21 and the sub-eccentric block 22, reducing the adjustment difficulty of the exciting force and saving the later use and maintenance costs.

[0025] Please refer to Figure 4 , Figure 8 , Figure 9 and Figure 10, Considering that the vibrating screen is driven to work when the main shaft 2 rotates, at this time, dust will be generated during screening, causing 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 cage 6. The cage 6 is equipped with rolling elements 64 and rollers 65, so that the rolling elements 64 and rollers 65 are evenly distributed between the outer ring 3 and the inner ring 4, preventing the rolling elements 64 and rollers 65 from contacting and colliding with each other, ensuring that each rolling element 64 and roller 65 can roll normally on their respective tracks, thereby improving the running accuracy and stability of the rotating part. During the operation of the rotating part, the cage 6 can bear a certain load and evenly transfer the load to the rolling elements. When the rotating part bears radial or axial loads, the cage 6 distributes the load to each rolling element 64 and roller 65, enabling the rolling elements 64 and rollers 65 to jointly bear the load and preventing individual rolling elements 64 and rollers 65 from being damaged due to excessive load, thereby improving the overall load-bearing capacity of the rotating part. The inner side of the cage 6 is connected to the inner ring 4, the outer side of the cage 6 is provided with an outer ring 3, sealing rings 5 are respectively provided on the left and right sides of the cage 6, 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 the lubricating grease from leaking outwards, keeping the lubricating grease inside the rotating part, continuously providing good lubrication for the rotating part, and prolonging the service life of the rotating part. At the same time, the entry of external dust, moisture, impurities, etc. into the rotating part will exacerbate the wear of the rotating part and reduce the accuracy and performance of the rotating part. The cage 6 can act as a barrier to prevent these impurities from entering the interior of the rotating part, protecting components such as the outer ring 3, inner ring 4, cage 6, rolling elements 64 and rollers 65 of the rotating part from being contaminated. A heat dissipation part 7 is provided on the sealing ring 5 located outside the exciter housing 1. A clamping part 8 is connected to the heat dissipation part 7, and the heat dissipation part 7 is connected to the main shaft 2 through the clamping part 8. The heat dissipation part 7 scrapes the surface of the sealing ring 5 and at the same time generates wind, which is beneficial to scraping off the dust accumulated on the surface of the sealing ring 5, and the wind generated by the heat dissipation part 7 blows away the scraped dust.

[0026] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7, considering that when the device is in use, it works with an existing vibrating screen. During the operation of the vibrating screen, dust will be generated, 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 clamping grooves 31. A semi-circular sealing ring 32 is arranged on the outer side of the inner part of the clamping groove 31. L-shaped clamping rings 33 are respectively arranged on the opposite sides of the two clamping grooves 31. The clamping groove 31 is used for clamping the sealing ring 5, and the sealing ring 5 is clamped therein to complete the fixation of the sealing ring 5. The semi-circular sealing ring 32 arranged inside the clamping groove 31 abuts against the sealing ring 5 to form a seal to prevent external pollutants from entering the inside of the rotating parts. At the same time, a clamping ring 33 is arranged inside the clamping groove 31. The clamping ring 33 is clamped with the sealing ring 5. After the sealing ring 5 is fixed, when the rotating parts work, the clamping ring 33 can effectively prevent the sealing ring 5 from being thrown out. At the same time, a seal is formed again between the clamping ring 33 and the sealing ring 5 to enhance the sealing effect. Oval clamping grooves 34 are respectively opened on the opposite sides of the two clamping grooves 31. The inner ring of the clamping groove 31 is chamfered. By providing the clamping groove 34, when installing the sealing ring 5, the fixation of the sealing ring 5 can be realized, and the firmness of the fixation of the sealing ring 5 can be enhanced to prevent the sealing ring 5 from separating from the outer ring 3 and the inner ring 4. Convex grooves 41 are respectively opened at the left and right ends of the inner ring 4. Sealing convex rings 42 are respectively arranged on the opposite sides of the two convex grooves 41. The inner side of the convex groove 41 is chamfered. An isolation raceway 43 is arranged at the center of the inner ring 4. By chamfering the inner side of the convex groove 41, it is convenient for the sealing ring 5 to be quickly clamped in the convex groove 41 and to be connected with the inner ring 4. At the same time, a sealing convex ring 42 is arranged inside the convex groove 41. After the sealing ring 5 is inserted into the convex groove 41, the sealing ring 5 abuts against the sealing convex ring 42 to form a seal again. The sealing ring 5 is circular and hollow inside. A plurality of reinforcing ribs 59 are arranged inside the sealing ring 5. The reinforcing ribs 59 divide the cavity of the sealing ring 5. Setting the inside of the sealing ring 5 to be hollow is beneficial to reducing the noise generated by the rotation of the rotating parts. At the same time, the reinforcing ribs 59 are arranged inside the sealing ring 5 to ensure the overall rigidity of the sealing ring 5. A semi-circular sealing groove 51 corresponding to the semi-circular sealing ring 32 is arranged on the outer wall of the sealing ring 5. A clamping protrusion 53 corresponding to the clamping groove 34 is arranged on the left side of the semi-circular sealing groove 51. A sealing baffle 54 is arranged on the left side of the clamping protrusion 53. A clamping ring 52 corresponding to the clamping ring 33 is arranged on the right side of the semi-circular sealing groove 51. Through the cooperation of the clamping protrusion 53 and the sealing baffle 54, 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 dust removing part 7 scrapes and removes dust, the sealing baffle 54 will also prevent dust from entering the inside of the rotating parts to prevent dust from polluting the components inside the rotating parts. A clamping ring 52 corresponding to the clamping ring 33 is arranged on the right side of the semi-circular sealing groove 51,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 elliptical and inclined upward. By providing the guide ring 55, when disassembling the sealing ring 5, the sealing ring 5 can be disassembled 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 dissipation member 7, making the rotation of the heat dissipation member 7 smoother. The right end of the sealing ring 5 is provided with a fixing groove 56. The fixing groove 56 is used to abut against the edge of the cage 6. By the fixing groove 56 abutting against the edge of the cage 6, the sealing ring 5 plays a clamping role on the cage 6, preventing the cage 6 from shaking.

[0027] Please refer to 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 block 21 and the auxiliary eccentric block 22, the main shaft 2 will push against the inner ring 4, the rolling elements 64 and the rollers 65 to extrude the outer ring 3. At the same time, since there is a gap between two rollers of the existing bearing, when it moves to a certain angle, the force will act in the gap, resulting in bearing damage. The cage 6 respectively includes two outer rings 61 and inner rings 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 that of the inner ring 62. Spacing rods are respectively connected between the outer ring 61 and the inner ring 62, and between the inner ring 62 and the inner ring 62. The spacing rods between the outer ring 61 and the inner ring 62 and the spacing rods between the inner ring 62 and the inner ring 62 are arranged in a staggered manner. When installing the rolling elements 64 and the rollers 65, the rolling elements 64 and the rollers 65 are also arranged in a staggered manner. 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 occurrence probability of bearing failures, improve the operation reliability of the equipment, reduce the maintenance cost and downtime. A placement frame is formed between the outer ring 61 and the inner ring 62 through the spacing rods. Limiting blocks 63 are respectively fixed on the opposite sides of the outer ring 61 and the inner ring 62, and on the opposite sides of the inner ring 62 and the inner ring 62. The limiting blocks 63 are located in the placement frame. Rollers 65 are arranged in the placement frame between the outer ring 61 and the inner ring 62, and rolling elements 64 are arranged in the placement frame between the two inner rings 62. Circular grooves are respectively arranged at the left and right ends of the rollers 65 and the rolling elements 64. The rolling elements 64 and the rollers 65 are connected to the limiting blocks 63 on the outer ring 61 and the inner ring 62 through the grooves, and the positions of the rolling elements 64 and the rollers 65 are limited by the limiting blocks 63, so that an appropriate gap is maintained between the rolling elements 64 and the rollers 65, reducing the friction and wear between the rolling elements 64 and the rollers 65, and between the rolling elements 64 and the rollers 65 and the outer ring 3 and the inner ring 4, and can further reduce the friction power consumption of the rotating part, improve the efficiency and service life of the rotating part. The rollers 65 are frustum-shaped, the rolling elements 64 are hourglass-shaped, and the rolling elements 64 and the rollers 65 are arranged in a staggered manner.

[0028] Please refer to Figure 4 and Figure 10, considering that dust will accumulate on the rotating part after it is lifted, it is necessary to scrape the dust off the rotating part at this time. At the same time, after the rotating part works for a long time, heat will be generated, and it is also necessary to cool the rotating part at this time. A plurality of blades 71 are fixed along the circumference of the outer wall of the heat sink 7. Cleaning notches 711 are respectively formed on the blades 71. The cleaning notches 711 are correspondingly connected to the guide rings 55 on the sealing ring 5. A plurality of mounting grooves 72 are formed along the circumference at one end of the heat sink 7 close to the sealing ring 5. Clamping blocks 73 are respectively slidably connected in the mounting grooves 72. The clamping blocks 73 can be attached to the main shaft 2. The clamping member 8 is threadedly connected to the heat sink 7. An inclined angle 81 is provided at one end of the clamping member 8 close to the heat sink 7. The other end of the clamping member 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 notches 711 on the blades 71 are clamped on the guide rings 55. After the clamping is completed, an existing wrench is used to connect the clamping member 8 to the heat sink 7. The inclined angle 81 on the clamping member 8 will abut against the clamping block 73. Due to the action of the inclined angle 81, the clamping block 73 will slide towards the main shaft 2. As the clamping member 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 abuts against the sealing ring 5 to scrape the dust on the sealing ring 5. At the same time, wind will be generated after the blade 71 rotates, blowing away the scraped dust, and the generated wind will cool the rotating part.

[0029] The present invention is installed on an existing vibrating screen of equipment and used in cooperation with an existing power source to drive the main shaft 2 to rotate. The device is fixed on the side plate of the equipment to be installed. Two groups of main shafts 2 and gears 23 are respectively installed inside the exciter housing 1. Main eccentric blocks 21 and auxiliary eccentric blocks 22 are installed at both ends of the main shaft 2 of the main shaft, and the angles between the main eccentric blocks 21 and the auxiliary eccentric blocks 22 are adjusted to appropriate angles according to requirements. The angles of the four groups of 210 and the auxiliary eccentric blocks 22 must be the same. Then the end cover is installed on the auxiliary eccentric block 22, and the main eccentric block 21 and the auxiliary eccentric block 22 are fixed integrally with the main shaft 2. The external motor is connected to the end cover through a coupling, and the motor torque is transmitted to the main shaft 2. The main shaft 2 drives the gear 23 inside the exciter housing 1 to rotate. The two groups of gears 23 rotate synchronously and reversely to drive the two groups of main eccentric blocks 21 and auxiliary eccentric blocks 22 to rotate reversely. The two groups 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 adjust the angles between the main eccentric blocks 21 and the auxiliary eccentric blocks 22 according to the on-site situation to meet different excitation force requirements. When the main shaft 2 rotates, the lower end of the blade 71 abuts against the sealing ring 5 to scrape the dust on the sealing ring 5. At the same time, wind will be generated after the blade 71 rotates, blowing away the scraped dust, and the generated wind will cool the rotating part.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
