The idlers 300 are plural, the idlers 300 are provided around the drum 400, and the gravity sensor is provided on the idlers 300 located at the bottom of the drum 400 to detect the weight of the drum 400.

In an embodiment provided by the present invention, the noise reducing medium comprises a first noise reducing medium 110 and a second noise reducing medium 120, and the mounting cavity 10 comprises: a first chamber 11 and a second chamber 12, the first noise reducing medium 110 being disposed in the first chamber 11, the second noise reducing medium 120 being disposed in the second chamber 12; the moving assembly 2 is disposed between the first chamber 11 and the second chamber 12 to compress or release the first noise reduction medium 110 and/or the second noise reduction medium 120. This arrangement enables coupling of vibration or noise with the first noise reduction medium 110 and the second noise reduction medium 120, and by arranging the moving assembly 2 to periodically press or release the first noise reduction medium 110 and/or the second noise reduction medium 120 by the moving assembly 2, low-frequency vibration or noise to which the first noise reduction medium 110 and/or the second noise reduction medium 120 is coupled can be converted into high-frequency vibration or noise, and energy converted into other forms is absorbed by the first noise reduction medium 110 and/or the second noise reduction medium 120, thereby optimizing noise reduction effects.

Specifically, the moving assembly 2 comprises: a partition plate 20 disposed in the installation cavity 10, and dividing the installation cavity 10 into a first chamber 11 and a second chamber 12 by the partition plate 20; and a moving member 21 disposed at a side of the partition plate 20 and located in the first chamber 11 and/or the second chamber 12, wherein the moving member 21 is movably disposed in a direction approaching or separating from the partition plate 20. Wherein the diaphragm 20 is fixedly disposed in the mounting chamber 10, and the moving member 21 is movable relative to the diaphragm 20 to compress or release the first noise reduction medium 110 and/or the second noise reduction medium 120.

The volume ratio of the first chamber 11 to the second chamber 12 is 1:2; the moving member 21 is located in the first chamber 11, and the first chamber 11 is disposed close to the bracket 200 with respect to the second chamber 12. In actual measurement, in the frequency spectrum of vibration and noise emitted by the pipe belt conveyor, the ratio of low frequency to high frequency is 1:2, and further the ratio of the volume of the first chamber 11 to the volume of the second chamber 12 is 1:2, so that the noise reduction effect on the pipe belt conveyor is improved.

In practical implementation, a first interval is formed between the circumferential side surface of the moving member 21 and the inner wall surface of the first chamber 11; and/or a second gap is provided between the circumferential side surface of the moving member 21 and the inner wall surface of the second chamber 12. This avoids the problem that the circumferential side surface of the moving member 21 rubs against the inner wall surface of the first chamber 11 or the inner wall surface of the second chamber during the movement of the moving member 21, thereby increasing the urging force of the moving member 21.

In this application, the moving assembly 2 further comprises: and a driving unit 22 disposed on the partition 20 and connected to the moving unit 21, wherein the driving unit 22 is telescopically disposed and drives the moving unit 21 to move by the driving unit 22. This arrangement enables the noise reduction effect of the noise reduction mechanism to be optimized by controlling the drive part 22 and thus the periodic movement of the moving part 21.

In the embodiment provided by the present invention, the driving part 22 includes: the plurality of piezoelectric ceramic pieces 220 are stacked and connected with each other, and the plurality of piezoelectric ceramic pieces 220 are in driving connection with the moving part 21; the piezoelectric ceramic plates 220 are connected to a voltage source, and the voltage source drives the piezoelectric ceramic plates 220 to deform, so that the piezoelectric ceramic plates 220 drive the moving component 21 to move. The piezoelectric ceramic is an information functional ceramic material capable of converting mechanical energy and electric energy into each other, namely, the piezoelectric effect, and the piezoelectric ceramic can be deformed correspondingly by introducing forward voltage into the piezoelectric ceramic, so that the shape of the piezoelectric ceramic is changed and the movable part 21 is driven to advance or retract. Through selecting for use piezoceramics, can effectively save the space inside casing 1, need not to adopt drive arrangement such as electronic jar of complicated structure. Moreover, the piezoelectric ceramics are sensitive to voltage, and the moving member 21 can be driven to advance or contract in a short time by changing the output voltage of the adjustable voltage source.

Preferably, the moving member 21 is plate-shaped.

The filling rate of the first noise reducing medium 110 in the first chamber 11 is 85% to 95%. Preferably, the filling ratio of the first noise reducing medium 110 is 90%, the filling material is in a high state, the first noise reducing medium is coupled with the low frequency vibration or the low frequency noise to generate the vibration associated with the low frequency vibration or the low frequency noise, the first noise reducing medium collides with each other in the limited and narrow first chamber 11 to consume a part of the vibration energy, and then the moving member 21 is pushed, the volume of the first chamber 11 is reduced, so that the filling ratio of the first noise reducing medium 110 is rapidly increased, for example, from 90% to 95%, and the vibration frequency of the first noise reducing medium 110 is rapidly increased, so that the low frequency vibration/noise is converted into the high frequency vibration/noise.

Further, the diameter of the second noise reducing medium 120 is smaller than that of the first noise reducing medium 110, small-particle second noise reducing medium 120 is more easily coupled with high-frequency vibration or high-frequency noise, the second noise reducing medium can absorb high-frequency noise and vibration generated by the pipe belt machine in the operation process, and besides, the high-frequency vibration/noise generated by the action of the first noise reducing medium 110 and the moving part 21 is also transmitted to the second noise reducing medium 120 through the moving part 21, the partition plate 20 and the shell 1, and the high-frequency vibration/noise is absorbed by the action of the second noise reducing medium and is converted into energy in other forms such as heat energy to be released in the shell, so that the low-frequency vibration/noise is absorbed.

In the present application, the first noise reduction medium 110 and/or the second noise reduction medium 120 are made of a particulate material, such as a metal, a nonmetal, or a polymer composite material. The shape of the particulate material is regular or irregular polyhedron. It is noted that the particulate material is preferably iron-based particles, aluminum-based particles, nickel-based particles, tungsten-based particles, chromium-based particles, sodium-based particles, magnesium-based particles, manganese-based particles, calcium-based particles, copper-based particles, zinc-based particles, scandium-based particles, titanium-based particles, glass particles, oxide ceramics, or the like. The particle damping is different from common solid, liquid and gas, and has the advantages of small volume, high temperature resistance, high reliability and the like. Also, the shape of the particulate material may be spherical, ellipsoidal, polyhedral, etc.

Preferably, the first noise reducing medium is iron particles with a diameter of 4mm to 10mm, and the second noise reducing medium is nickel particles with a diameter of 0.1mm to 3mm.

The diameter of the first noise reduction medium 110 is larger than the diameter of the second noise reduction medium 120.

In this embodiment, two noise reducing media with different diameters are provided, wherein the diameter of the first noise reducing medium is larger, and the large-particle first noise reducing medium is more easily coupled with low-frequency vibration or low-frequency noise. In this embodiment, the low-frequency vibration or low-frequency noise refers to vibration or noise having a frequency within a range of 1Hz to 300 Hz.

In the present application, the accommodating weight of the current load in the drum 400 has a certain correlation with the vibration/noise, for example, the weight of the load increases and the frequency of the vibration/noise decreases. By this rule, the weight of the carrier is detected in real time, thereby obtaining the frequency of vibration/noise associated with the weight of the carrier, for example, in the range of 1-500kg of the total weight of the carrier and the drum 400, the frequency of vibration/noise generated is about 1-500Hz decreasing. So that vibration or noise can be more effectively reduced by selecting the driving period of the driving part 22 corresponding to the frequency. Specifically, the data of the gravity sensor is within the interval of 1kg-500kg, and the control system adjusts the period to linearly decrease within the interval of 1 Hz-3 Hz.

If the frequency of the noise/vibration is high and the driving period is high, the diameter of the first noise reduction medium is large, the time required for the noise/vibration with high frequency to drive the first noise reduction medium to resonate is also long, and at this time, if the first noise reduction medium is not driven to resonate completely to push the moving part 21, only a part of low-frequency noise can be absorbed, and most of the low-frequency noise escapes. In contrast, if the frequency of the noise/vibration is low and the driving cycle is slow, although the low-frequency noise is absorbed by the first noise reducing medium, the first noise reducing medium is saturated and the moving member 21 is still not pushed out so that the internal energy of the first noise reducing medium cannot be converted into high-frequency noise, and the noise saturated by the first noise reducing medium continues to propagate to the outside.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
