[0034] Embodiment 1:

[0035] Reference Figures 1-3The application discloses an easily-observed powder vibrating device, which comprises a frame 1, a feeding hopper 2, a transparent discharging pipe 3, a transparent vibrating pipe 4, a vibrating frame 5 and a vibrating assembly 6. The frame 1 is a basic support structure of the whole vibrating device. The feeding hopper 2 is installed at the top end of the frame 1 and is used for loading powder materials to be vibrated, so as to facilitate the smooth feeding of the materials to the next step. The transparent discharging pipe 3 is connected below the feeding hopper 2 and forms a transparent material channel, so as to facilitate the observation of the flowing state of the materials and the vibrating process of the materials in the transparent discharging pipe 3. The transparent discharging pipe 3 can be a transparent silica gel pipe, so that the transparent discharging pipe 3 has a certain elasticity, and the impact force can be transmitted to the materials in the transparent discharging pipe 3 after the transparent discharging pipe 3 is impacted, so as to accelerate the vibration of the materials. The transparent vibrating pipe 4 is nested at the bottom of the transparent discharging pipe 3, the transparent vibrating pipe 4 impacts the transparent discharging pipe 3 periodically through the inner bottom wall of the transparent vibrating pipe 4, so as to vibrate the transparent discharging pipe 3, promote the compaction and uniform distribution of the powder materials in the transparent discharging pipe 3, and the transparent property of the transparent vibrating pipe 4 facilitates the direct monitoring of the vibrating process of the materials. The vibrating frame 5 is arranged at the bottom of the transparent vibrating pipe 4 and can be a transmission medium of vibrating energy. The vibrating assembly 6 is installed at the bottom of the frame 1 and is closely connected with the vibrating frame 5. The vibrating assembly 6 drives the vibrating frame 5 and the transparent vibrating pipe 4 to make periodic lifting movement, so as to realize the impact of the transparent vibrating pipe 4 on the transparent discharging pipe 3 and realize the vibrating treatment of the materials in the transparent discharging pipe 3.

[0036] In some embodiments, the vibrating device further comprises a vibrating constraint assembly 7, which comprises a fixed platform 71 and a transparent constraint pipe 72. The fixed platform 71 is arranged at the middle of the frame 1 and is fixedly connected with the frame 1. The fixed platform 71 is provided with the transparent discharging pipe 3 and the transparent vibrating pipe 4. The transparent constraint pipe 72 is arranged on the fixed platform 71 and is provided with the transparent vibrating pipe 4, so as to facilitate the movement of the transparent vibrating pipe 4 in the transparent constraint pipe 72. The transparent constraint pipe 72 constrains the transparent vibrating pipe 4, so that the transparent vibrating pipe 4 vibrates in a specified direction, so as to realize the controllable vibrating.

[0037] In some embodiments, the vibrating assembly 6 comprises a vibrating motor 61, a rotating shaft 62, a cam 63 and a vibrating wheel 64. The vibrating motor 61 is arranged at the bottom of the frame 1 and can provide the energy required by the vibration. The rotating shaft 62 is connected with the vibrating motor 61 and can drive the rotating shaft 62 to rotate. The cam 63 is connected with the rotating shaft 62 and can be a crank block with a notch on one side. The vibrating wheel 64 is arranged at the bottom of the vibrating frame 5 and is in transmission connection with the cam 63. During the rotation of the cam 63, the cam 63 is always in rolling contact with the vibrating wheel 64. Through the rotation of the cam 63, the vibrating wheel 64 is driven to rotate at different heights at the same time, so as to drive the vibrating wheel 64 to vibrate, and then realize the up-down vibration of the vibrating frame 5.

[0038] In some embodiments, the vibration assembly 6 further comprises a driving wheel 65 coaxially connected with the output shaft of the vibration motor 61 for transmitting the rotating power of the motor, and a driven wheel 66 coaxially connected with the rotating shaft 62, the driven wheel 66 being engaged with the driving wheel 65 to ensure stable transmission of the rotating power, while different transmission ratios between the driving wheel 65 and the driven wheel 66 can realize different periodic rotations of the cam 63, thereby realizing different vibration effects.

[0039] In some embodiments, the first connecting assembly 8 is fixedly arranged on the vibration frame 5, and the first connecting assembly 8 can be a spring clamp, which is a prior art and will not be described here. The bottom of the first connecting assembly 8 can be welded and fixed on the vibration frame 5, and the vibration assembly 6 can be independently maintained through detachable connection between the first connecting assembly 8 and the transparent vibration tube 4.

[0040] In some embodiments, the second connecting assembly 9 is fixedly arranged on the fixed platform 71, and the second connecting assembly 9 can be a spring clamp, which is a prior art and will not be described here. The bottom of the second connecting assembly 9 can be welded and fixed on the fixed platform 71, and the transparent constraint tube 72 can be maintained through detachable connection between the second connecting assembly 9 and the transparent constraint tube 72.

[0041] In some embodiments, the transparent vibration tube 4 and the transparent constraint tube 72 are made of acrylic material, which has good transparency for facilitating observation of the vibration process of the powder by the operator, and has good corrosion resistance and mechanical strength, which can meet the use requirements in a long-time vibration environment.

[0042] In some embodiments, the transparent discharge tube 3 is provided with a scale, which facilitates observation of the height of the material in the transparent discharge tube 3 after vibration, so as to obtain the vibration density of the powder according to the weight of the material and the size of the transparent discharge tube 3. Specifically, assuming that the feeding amount M is 3000g, the inner diameter D of the transparent discharge tube 3 is 2.8cm, and the column height of the material in the transparent discharge tube 3 is L cm after sufficient vibration, the vibration density of the material can be calculated by the formula ρ=M / 0.25*D2*L.

[0043] The specific working principle is as follows:

[0044] In use, the operator pours the powder material into the hopper 2, and the powder material enters the transparent discharge tube 3 through the hopper 2. The falling of the material can be observed, and then the vibration motor 61 is started, which drives the cam 63 to rotate through the rotating shaft 62. The cam 63 drives the vibration wheel 64 to rotate in the rotating process, and the vibration wheel 64 is in contact with the cam surface at different heights, so that the vibration wheel 64 is at different heights in the rotating process of the cam 63, so that the vibration frame 5 and the transparent vibration tube 4 vibrate up and down. In the process of the transparent vibration tube 4 vibrating up and down, the bottom wall of the transparent vibration tube 4 will periodically hit the bottom wall of the transparent discharge tube 3. Under the action of vibration, the powder material in the transparent discharge tube 3 is continuously impacted and extruded, so as to realize the vibration and compaction of the material.

[0045] Since the transparent vibration tube and the transparent constraint tube are both made of acrylic material, they have good transparency, so the operator can clearly observe the state change of the powder material in the vibration and compaction process, such as the gradual reduction of the gap between the particles and the densification of the material. In this way, the operator can adjust the operation parameters in time according to the observation results to ensure the product quality and operation efficiency.

[0046] When the vibration and compaction is completed, the height of the material column in the transparent discharge tube 3 can be read, and the vibration and compaction density of the material can be calculated combined with the weight of the material and the diameter of the transparent discharge tube 3. Combined with the observed shape after vibration and compaction, data support is provided to solve the problem of broken wire in the tungsten rod wire drawing process.

[0047] Embodiment 2:

[0048] Reference Figure 4 The difference between this embodiment and embodiment 1 is:

[0049] The transparent vibration tube 4 includes a tube body 41 and a limiting ring 42. The tube body 41 penetrates through the transparent constraint tube 72, and the bottom of the tube body 41 is connected with the vibration frame 5, so that the vibration energy can be transmitted to the material. The limiting ring 42 is arranged at the top of the tube body 41, and the outer diameter of the limiting ring 42 is greater than the diameter of the transparent constraint tube 72, so that the tube body 41 can be stably supported in the vertical direction, and the tube body 41 can be prevented from falling in the vibration process.
