[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] See also Figure 1-Figure 3 As shown, a ball mill sound insulation and noise reduction device comprises:

[0032] A bottom plate 1, a support seat 3 is installed in the middle of the top outer wall of the bottom plate 1, an outer shell 2 is arranged on the top outer wall of the support seat 3, and strip grooves 10 are opened on one side of the top outer wall of the bottom plate 1 near both ends;

[0033] The chassis 5 is installed on the side of the top outer wall of the bottom plate 1 away from the strip groove 10. A driving mechanism 11 is arranged inside the chassis 5. One end of the driving mechanism 11 is connected to the outer shell 2. A sound-absorbing cotton 14 is installed on the inner wall of the chassis 5 near the driving end of the driving mechanism 11.

[0034] The two moving mechanisms 9 are respectively installed on the inner walls of the two strip grooves 10, and the same baffle 8 is installed on the top outer walls of the two moving mechanisms 9. A covering mechanism 7 is installed on the outer wall of one side of the baffle 8, and one end of the covering mechanism 7 is clamped on the outer wall of one side of the outer shell 2.

[0035] As can be seen from the above, the driving mechanism 11 inside the chassis 5 generates a lot of noise when working. The noise is absorbed by the sound-absorbing cotton 14 to reduce the noise and reduce noise emission. The movement of the covering mechanism 7 is controlled by the moving mechanism 9, so as to facilitate the closing or opening of the outer shell 2 and the placement and discharge of materials.

[0036] Specifically, an inner shell 16 is installed on the inner wall of one side of the outer shell 2, and a sound-absorbing cotton 15 is sleeved on the circumferential outer wall of the inner shell 16. A gap is left between the sound-absorbing cotton 15 and the inner wall of the outer shell 2, and mounting plates 17 are provided on the outer wall of one side of the inner shell 16 near both ends.

[0037] As can be seen from the above, by setting the sound-absorbing cotton 15, the sound-absorbing cotton 15 absorbs sound on the outside of the inner shell 16 to isolate the transmission of noise. In addition, there is a layer of gap between the sound-absorbing cotton 15 and the outer shell 2, so that the volume of noise is lower after it is transmitted.

[0038] Specifically, the driving mechanism 11 includes a motor 1101, which is fixedly installed on the inner wall of one side of the chassis 5 near the bottom, one end of the output shaft of the motor 1101 is sleeved with a main gear 1102, and a transmission rod 1105 is rotatably inserted into the chassis 5 near the center of one end of the outer shell 2, one end of the transmission rod 1105 is fixedly installed at the center of one end of the outer shell 2, and the other end of the transmission rod 1105 is sleeved with a bearing fixing seat 1103, and the bearing fixing seat 1103 is fixedly installed on the inner wall of one side of the chassis 5, and a transmission gear 1104 is sleeved on the circumferential outer wall of the transmission rod 1105, and the transmission gear 1104 and the main gear 1102 are meshed with each other.

[0039] As can be seen from the above, after starting the motor 1101, it drives the main gear 1102 to rotate, the main gear 1102 drives the meshing transmission gear 1104 to rotate, the transmission gear 1104 drives the transmission rod 1105 to rotate, and then drives the outer shell 2 to rotate, so that the material can be ground by the steel balls in the inner shell 16.

[0040] Specifically, an installation opening is opened on the outer wall of one side of the chassis 5 near the motor 1101, a heat sink 12 is clamped on the inner wall of the installation opening near the motor 1101, a fan 13 is installed on the surface of the heat sink 12, a dustproof net 4 is clamped on the inner wall of the installation opening near the outer side of the heat sink 12, a heat dissipation port is opened on the top outer wall of the chassis 5, and a heat dissipation net 6 is clamped on the inner wall of the heat dissipation port.

[0041] As can be seen from the above, during the operation of motor 1101, fan 13 is started to dissipate heat, thereby reducing the operating temperature of motor 1101 and reducing noise. The heat dissipation inside chassis 5 is facilitated by heat dissipation plate 12 and heat dissipation net 6, and the dustproof net 4 is used to reduce the entry of external dust into chassis 5.

[0042] Specifically, the moving mechanism 9 includes an electric slide rail 901, and the two electric slide rails 901 are respectively fixedly mounted on the inner walls of the two strip grooves 10. A slider 902 is slidably clamped on the outer wall of one side of the two electric slide rails 901. The same clamping seat 903 is installed on the top outer wall of the two sliders 902, and the baffle 8 is clamped on the inner wall of the clamping seat 903.

[0043] As can be seen from the above, the electric slide rail 901 drives the slider 902 to move, thereby driving the clamping seat 903 and the baffle 8 to move, so as to facilitate the movement of the position of the covering mechanism 7.

[0044] Specifically, the covering mechanism 7 includes a round seat 701 , one end of which is rotatably plugged with a rotating drum 702 , one end of which is fixedly mounted with a circular plate 703 , and one end of which is clamped on an inner wall of one side of the outer shell 2 .

[0045] As can be seen from the above, a closed device is formed between the circular plate 703 and the outer shell 2 to facilitate the grinding of materials. After the grinding is completed, the circular plate 703 is moved out by the moving mechanism 9 to open the outer shell 2, and then the mounting plate 17 on the surface of the inner shell 16 is opened to discharge the materials.

[0046] Working principle: When in use, the electric slide rail 901 drives the slider 902 to move, so that the circular plate 703 leaves the outer shell 2, the mounting plate 17 is opened, and the material is poured into the inner shell 16, and then the electric slide rail 901 is started, so that the circular plate 703 is clamped with the outer shell 2, and then the motor 1101 is started. The motor 1101 drives the rotation of the main gear 1102, the transmission gear 1104 and the transmission rod 1105, and then drives the rotation of the outer shell 2 and the inner shell 16, and grinds the material through the small steel ball. During the operation, the motor 1101 generates a lot of noise, which is absorbed by the sound-absorbing cotton 14 to reduce the noise and reduce the noise emission. The sound-absorbing cotton 15 is set, and the sound-absorbing cotton 15 absorbs the sound on the outside of the inner shell 16 to isolate the transmission of noise. In addition, there is a layer of gap between the sound-absorbing cotton 15 and the outer shell 2, so that the volume of the noise is lower after it is transmitted. After waiting for the grinding to be completed, the circular plate 703 is removed again, and the baffle 8 is opened to put in the material.

[0047] Embodiment 2:

[0048] refer to Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that it also includes a temperature sensor 18 and an alarm 19. The temperature sensor 18 is fixedly installed on the inner wall of one side of the chassis 5 near the position above the motor 1101 by bolts, and the alarm 19 is installed on the top outer wall of the chassis 5. The temperature sensor 18 and the alarm 19 are electrically connected.

[0049] As can be seen from the above, by setting the temperature sensor 18, the temperature sensor 18 sets a high temperature threshold. When the working environment temperature of the motor 1101 reaches the high temperature threshold, the signal is transmitted to the alarm 19. The alarm 19 alarms to remind the staff to deal with it. The staff then turns off the motor 1101 and lowers the temperature of the chassis 5 to facilitate subsequent work.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
