It is mainly used for transportation in coal mining working faces and gate roads in mining areas, and can also be used in driving working faces of coal roadways and semi-coal rock roadways. It can transport upwards or downwards. Generally, the upward transportation angle does not exceed 35 degrees, and the downward transportation angle does not exceed 25 degrees. Actually, it is preferably not more than 20 degrees. The scraper conveyor has the advantages that its transportation capacity is not affected by the size and humidity of the cargo, its body height is small and convenient for loading, its body length can be adjusted conveniently, and its body is strong enough to be used in working faces with blasting coal loading, so it is widely used in many coal mines. However, its disadvantages are: large working resistance, high power consumption, serious wear of the chute, easy chain breakage when maintained and used improperly, and a certain limitation on the transportation distance.

[0003] The existing scraper conveyor will generate a large amount of noise during operation. This kind of noise will affect the working environment of on-site workers, reduce the comfort of the working environment, affect the physical health of the staff, and is not conducive to on-site operation.

[0023] Embodiment:

[0024] Please refer to Figures 1-3 , a sound insulation structure of a scraper conveyor in a coal preparation plant, comprising: a scraper conveyor body 1, the bottom surface of the scraper conveyor body 1 is detachably connected with an extended base 2; and two sound insulation components, both of the two sound insulation components include: a sound insulation part, a heat dissipation part and a fixing part. Both of the two sound insulation parts include: an outer shaping shell 8, a lightweight sound-absorbing foam layer 9, a high-density damping material layer 10 and two fitting blocks 11. The outer shaping shell 8 is arranged above the extended base 2, the lightweight sound-absorbing foam layer 9 is fixedly connected to the inner wall of the outer shaping shell 8, the high-density damping material layer 10 is fixedly connected to the inner wall of the outer shaping shell 8, the two fitting blocks 11 are respectively fixedly connected to the outer side walls of both sides of the outer shaping shell 8, two heat dissipation parts are respectively installed on one side of the corresponding sound insulation part for dissipating heat from the sound insulation part, and two fixing parts are respectively arranged on one side of the corresponding outer shaping shell 8.

[0025] In a specific embodiment of the present utility model, the scraper conveyor body 1 is propped up by the extension base 2 for installation and disassembly, and the sound insulation components are installed. The two sound insulation parts are connected relatively. The high-density damping material layer 10 absorbs vibration and reduces the sound energy transmitted through the casing. The lightweight sound-absorbing foam layer 9 further blocks the transmission of sound waves. The outer shaping shell 8 protects the internal materials from the influence of the external environment and also plays a certain role in sound insulation. When maintenance is required, the external heat dissipation copper plate 5 is removed, then the connecting copper pipe 6 is pushed inward, and then the two concave fixing frames 12 are removed to unlock the two sound insulation parts. Then, two workers stand on both sides of the sound insulation parts respectively, and the sound insulation parts are lifted as a whole through the matching block 11, so as to repair the scraper conveyor body 1 inside. When installation is required, it only needs to align and place the sound insulation parts and the positioning extension 3, which is convenient for disassembly and reinstallation of the parts, ensuring the best noise reduction effect without affecting the normal operation and maintenance of the scraper conveyor, improving the comfort of the working environment, and meeting the environmental noise standards.

[0026] Specifically, both of the two heat dissipation parts include: an external limiting extension 4, an external heat dissipation copper plate 5, a connecting copper pipe 6 and an internal heat dissipation copper plate 7. The external limiting extension 4 extends and is arranged on the top surface of the extension base 2. A through hole is opened on one outer wall of the external limiting extension 4. The external heat dissipation copper plate 5 is detachably connected to one outer wall of the external limiting extension 4. The connecting copper pipe 6 is detachably connected to one outer wall of the external heat dissipation copper plate 5, and the connecting copper pipe 6 cooperates with the through hole. The internal heat dissipation copper plate 7 is fixedly connected to one end of the connecting copper pipe 6, and the internal heat dissipation copper plate 7 is detachably connected to one outer wall of the high-density damping material layer 10.

[0027] In this embodiment, the internal and external spaces are connected through the external heat dissipation copper plate 5, the connecting copper pipe 6 and the internal heat dissipation copper plate 7. Thus, when consuming the internal vibration and kinetic energy, the heat emitted is absorbed and conducted out to avoid damage caused by excessive internal heat.

[0028] Specifically, two groups of positioning extensions 3 are extended and arranged on the top surface of the extension base 2. Each group of positioning extensions 3 has two, and each group of two positioning extensions 3 respectively cooperate with the corresponding outer shaping shell 8.

[0029] In this embodiment, the outer shaping shell 8 is restricted by the positioning extension 3, thereby improving the positioning effect during installation.

[0030] Specifically, both of the two fixing parts include: a concave fixing frame 12. The concave fixing frame 12 is arranged between the outer walls of the two matching blocks 11, and a hand-held groove is extended and arranged on the top surface of the concave fixing frame 12.

[0031] In this embodiment, the matching blocks 11 on both sides are fixed by the concave fixing frame 12, thereby improving the sealing effect.

[0032] Specifically, on one side of each of the two sound insulation components, a lead-out port is provided, and the two lead-out ports cooperate with the scraper conveyor body 1.

[0033] In this embodiment, by cooperating the lead-out port with the scraper conveyor body 1, the subsequent transfer track is installed.

[0034] Specifically, a recessed groove is provided on the outer wall of one side of each of the four matching blocks 11.

[0035] In this embodiment, the concave fixing frame 12 is fitted through the recessed groove, thereby achieving the effect of installation and fixation.

[0036] Working principle: The scraper conveyor body 1 is supported by the extension base 2 for installation and disassembly, and the sound insulation components are installed. The two sound insulation components are connected relatively. The high-density damping material layer 10 absorbs vibration and reduces the sound energy transmitted through the machine shell. The lightweight sound-absorbing foam layer 9 further blocks the transmission of sound waves. The outer shaping shell 8 protects the internal materials from the influence of the external environment and also plays a certain role in sound insulation. When maintenance is required, the external heat-dissipating copper plate 5 is removed, then the connecting copper pipe 6 is pushed inward, and then the two concave fixing frames 12 are removed to unlock the two sound insulation components. Then, two workers stand on both sides of the sound insulation components respectively, and the sound insulation components are lifted as a whole through the matching blocks 11, so as to repair the scraper conveyor body 1 inside. When installation is required, it is only necessary to align and place the sound insulation components and the positioning extension 3, which is convenient for disassembling and reinstalling components, ensuring the best noise reduction effect without affecting the normal operation and maintenance of the scraper conveyor, improving the comfort of the working environment, and meeting the environmental noise standards.

The wiring diagram of the power element and the power supply are common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and wiring layout of the present utility model will not be explained in detail.
