Description

Technical Field

[0001] This utility model relates to the field of dewatering screen technology, specifically to a direct-impact electric beater. Background Technology

[0002] Vibrating dewatering screens are mechanical equipment used for coal slime recovery and fine material dewatering and grading. This equipment not only needs to meet the requirements of coal slime recovery and fine material dewatering and grading, but also needs to achieve the following equipment indicators: large processing capacity, good dewatering effect, and strong adaptability.

[0003] The core equipment for achieving high-frequency, high-vibration-intensity mechanical characteristics is generally a percussion device. However, currently popular percussion devices often suffer from problems such as high noise, poor durability, and high maintenance rates.

[0004] In view of this, the applicant has developed a new generation of electric striking devices. Utilizing a design concept of large gap and low coefficient of friction, these devices feature adjustable striking frequency, simple structure, low failure rate, low maintenance requirements, and significant performance benefits. Utility Model Content

[0005] Therefore, this utility model provides a direct-impact electric striker to solve the problems of poor durability and high maintenance rate of existing strikers.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The direct-strike electric striking device disclosed in this utility model includes:

[0008] The drive device has its power output end connected to the tail end of the driving member and is adapted to drive the driving member to perform constant speed rotary motion or reciprocating linear motion.

[0009] The driven member has a groove on its side, and uses the groove to transmit power to the driving member through a high pair;

[0010] An energy storage device is vertically fixed on a frame, with a drive device installed at the top and a guide vertically installed at the bottom of the frame;

[0011] The striking head assembly is slidably mounted on the guide at both ends. The driven member is adapted to drive the striking head assembly to hammer the screen of the dewatering screen. The energy storage device is adapted to drive the striking head assembly to generate directional kinetic energy through the driven member.

[0012] Furthermore, the drive device includes a motor, a reducer, and a protective cover. The motor is mounted on the frame, and a protective cover is provided outside the motor. The power output end of the motor is connected to the reducer and drives the driving component to rotate through the reducer.

[0013] Furthermore, the driving component includes a crank and a lever. One end of the crank is coaxially connected to the driving device, and the other end of the crank is equipped with a lever adapted to drive the driven component to move up and down by turning the groove.

[0014] Furthermore, the driven member includes:

[0015] The lifting hook has a striking rod installed at the bottom, which is slidably inserted into the energy storage device, and an elastic body is installed inside the energy storage device;

[0016] A retaining ring is fixedly mounted on the striking rod and abuts against the elastic body. The end of the striking rod is provided with a connector, which is connected to the striking head assembly.

[0017] Furthermore, a shock-absorbing pulley is fitted onto the lever, and the gap between the shock-absorbing pulley and the surface of the groove is no more than millimeters.

[0023] This utility model discloses a direct-impact electric beater that drives a driving component to rotate via a drive device. The driving component then transmits power to itself, causing it to extend and retract vertically. During this process, the kinetic energy of the driving component is converted into potential energy in an energy storage device. Finally, the potential energy is released and converted back into kinetic energy, causing the striking head assembly to continuously strike the dewatering screen, generating vibration. This achieves the technical effects of coal slime recovery and fine-particle dewatering and grading. Compared to existing technologies, this device has the advantages of simple structure, durability, and ease of maintenance, solving the problems of poor durability and high maintenance rates in existing beaters.

Detailed Implementation

[0033] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please refer to this as well. Figures 1-6 The direct-impact electric beater disclosed in this utility model has the mechanical characteristics of high frequency and high vibration intensity. It is mainly used to drive the dewatering screen to generate high-frequency vibration, thereby economically and effectively recovering coal slime and realizing product dewatering. The technical solution of this utility model will be described below by way of specific embodiments.

[0035] In one specific embodiment of this utility model, the direct-strike electric impactor includes a drive device 1, a driven member 3, a striking head assembly 4, and an energy storage device 5. The power output end of the drive device 1 is a main shaft, which is connected to the tail end of the driving member 2 and coaxially driven, thereby driving the driving member 2 to perform constant-speed rotary motion or reciprocating linear motion. The driven member 3 has a groove 7 on its side, allowing the driving member 2 to slide within the groove 7, thus enabling a high-pair transmission with the driving member 2 to lift the driven member 3 and drive the striking head assembly 4 to move up and down.

[0036] In this embodiment, the energy storage device 5 is vertically fixed on the frame 6. An elastic body 9 is installed in the energy storage device 5. The elastic body 9 can convert the kinetic energy of the driven member 3 into elastic potential energy generated by the deformation of the elastic body 9. Specifically, one end of the elastic body 9 abuts against the frame 6, and the other end of the elastic body 9 is adapted to support the driven member 3, lifting the striking head assembly 4 to generate directional elastic potential energy. Then, the driven member 3 drives the striking head assembly 4 to fall, converting the elastic potential energy into kinetic energy to strike the dewatering screen 10. Specifically, when the groove 7 separates from the driven member 3, the elastic potential energy is released, thereby causing the driven member 3 to drive the striking head assembly 4 to hammer the dewatering screen 10, thereby generating a vibration load on the dewatering screen 10. On the other hand, a drive device 1 is installed on the top of the frame 6, and a guide 8 is vertically installed on the bottom of the frame 6. The two ends of the striking head assembly 4 are slidably mounted on the guide 8. When the driven member 3 drives the striking head assembly 4 to strike the dewatering screen 10, the dewatering screen 10 can vibrate along the direction of the guide 8.

[0037] In this embodiment, the elastic body 9 is a mechanical component such as a spring or a shock absorber, and the dewatering screen 10 is installed on the striking head assembly 4. Specifically, with the direction perpendicular to the ground as a reference, the installation angle of the dewatering screen 10 is between 30° and 90°, and the specific installation method is as follows:

[0038] I. Mid-position installation:

[0039] During installation, ensure the vertical distance between the dewatering screen 10 and the bottom surface of the channel steel of the impact head assembly 4 is between 386mm and 410mm. After determining the installation height, adjust the connecting bolts between the impact device and the driven member 3 to ensure the impact head assembly 4 is fully in contact with the dewatering screen 10. After adjusting the installation height, adjust the guide devices on both sides until the driven member 3 runs smoothly without obstruction.

[0040] 2. Offset installation:

[0041] During installation, ensure that the central axis of the impactor is aligned with the center of the dewatering screen 10. The vertical distance from the dewatering screen 10 to the bottom surface of the channel steel of the impact head assembly 4 should be between 386mm and 410mm. Additional support plates can be added to the side plates as needed to ensure installation strength. Normally, the mounting flange of the impact head assembly 4 is bolted to the side plate of the dewatering screen 10. There are several effective connection points on each side of the impact head assembly 4, which can be used according to actual working conditions.

[0042] In this embodiment, when determining the installation location, the specific installation method can be determined based on experience and on-site construction conditions. Both installation locations can achieve ideal striking effects. The striking effect of the offset installation is slightly better than that of the center installation, but it is more conducive to the normal operation of the striker reducer.

[0043] In some embodiments, the driving member 2 includes a crank 21 and a lever 22. One end of the crank 21 is coaxially connected to the drive device 1, and the other end of the crank 21 is connected to the lever 22. The lever 22 is adapted to drive the driven member 3 to move up and down by actuating the groove 7. In addition, a shock-absorbing pulley 23 is sleeved on the lever 22. The gap between the shock-absorbing pulley 23 and the surface of the groove 7 is no more than 5 mm, thereby preventing interference between the parts.

[0044] In some embodiments, the drive device 1 includes a motor 11, a reducer 12 and a protective cover 13. The motor 11 is mounted on the frame 6. The motor 11 is provided with a protective cover 13. The power output end of the motor 11 is connected to the reducer 12 and drives the driving member 2 to rotate through the reducer 12. A guide rail is provided inside the protective cover 13. A driven member 3 is slidably arranged on the guide rail to play a guiding role.

[0045] In some embodiments, the driven member 3 includes a lifting hook 31 and a retaining ring 33. A striking rod 32 is mounted at the bottom of the lifting hook 31 and slidably inserted into the energy storage device 5. Since an elastic body 9 is installed inside the energy storage device 5, the elastic body 9 can abut against the retaining ring 33 fixedly mounted on the striking rod 32, thereby converting the kinetic energy of the part into elastic potential energy when the driven member is lifted. A connector 34 is provided at the end of the striking rod 32, which can be connected to the striking head assembly 4. The striking head assembly 4 drives the striking head assembly 4 to strike the dewatering screen 10, generating a vibration load.

[0046] In this embodiment, as another optional technical solution, the energy storage device 5 is also equipped with a counterweight. Under the action of gravity, the counterweight drives the striking head assembly 4 to strike the dewatering screen 10 through the driven member 3. The dewatering screen 10 is not limited in specific shape and is mainly used to separate moisture from the material. It should be noted that the striking head assembly 4 can be equipped with multiple hammers to improve the hammering effect.

[0047] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
