[0028] During operation, in the prior art, based on the current rotary kiln, a large number of electric devices are combined when operating. When these electric devices drive the rotary kiln to rotate, the rotary kiln will generate a certain vibration, thereby causing an offset between the rotary kiln and the bracket, and even causing the rotary kiln to fall over, causing harm to the surrounding staff. In order to prevent such incidents from happening, first, the driving motor 52 is used to drive the crown gear 42 to rotate, and when rotating, the two sets of transmission screws 43 are driven to rotate through the transmission gear 44. Then, according to the size of the rotary kiln body 2, the transmission screw 43 is used to adjust the distance between the two sets of moving blocks 46, and the distance must be larger than the rotary kiln body 2. The adjustment is completed. Finally, place the rotary kiln body 2 on the base 1, and then adjust the position of the rotary kiln body 2 so that the first meshing belt 21 on the rotary kiln body 2 and the limiting pulley 462 are on the same horizontal plane. After the adjustment is completed, drive the transmission screw 43 to rotate again, so that the moving block 46 drives the limiting column 461 close to the rotary kiln body 2, and clamps the limiting pulley 462 on the first meshing belt 21. By clamping the limiting pulley 462 inside the first meshing belt 21, the rotary kiln body 2 can be prevented from shifting during rotation. At the same time, the rotary kiln body 2 can be limited by the limiting columns 461 arranged around it to prevent the rotary kiln body 2 from tipping over during rotation.

[0029] like Figure 4 and Figure 5 As shown, a driving assembly 5 is provided on the surface of the base 1; the driving assembly 5 includes a driving box 51; a supporting plate 54 is slidably connected to the driving box 51; a supporting box 55 is fixedly connected to the surface of the supporting plate 54; a driving shaft 56 is rotatably connected to the supporting box 55; a supporting pulley 57 is externally connected to the driving shaft 56; a second meshing belt 22 is fixedly connected to the middle of the rotary kiln body 2; the supporting pulley 57 is clamped on the second meshing belt 22;

[0030] During operation, when the rotary kiln body 2 is placed on the base 1, it is driven and supported by the driving component 5 on the base 1. The surface of the rotary kiln body 2 is also fixed with the second meshing belt 22. The supporting pulley 57 on the base 1 is clamped on the second meshing belt 22, and supported by the supporting pulley 57 and the supporting plate 54. The two sides are supported by components such as the limit column 461, and the second meshing belt 22 can also prevent the rotary kiln body 2 from shifting.

[0032] During operation, the rotary kiln body 2 will generate certain vibrations when it rotates. Long-term vibration may cause wear on the connection between the rotary kiln body 2 and the supporting pulley 57. The telescopic spring 53 at the bottom of the drive box 51 can have a shock-absorbing effect on the rotary kiln body 2. During vibration, the supporting plate 54 supported by the telescopic spring 53 can float up and down, thereby reducing the shock of the rotary kiln body 2.

[0033] like Figure 4 As shown, the side wall of the partition 45 is fixedly connected to a guide column 47; the guide column 47 is provided with two groups, respectively provided on both sides of the transmission screw 43; the guide column 47 is provided through the moving block 46;

[0034] During operation, the guide column 47 passes through both sides of the moving block 46. When the moving block 46 moves, the moving block 46 is limited by the guide column 47, which can prevent the moving block 46 from deviating during movement, causing the moving block 46 and the transmission screw 43 to be misaligned.

[0035] like Figure 5 As shown, the side wall of the support box 55 is fixedly connected to the drive motor 52; the drive shaft 56 is driven by the drive motor 52;

[0036] During operation, the driving motor 52 can drive the driving shaft 56 to rotate, thereby driving the supporting pulley 57, and the supporting pulley 57 drives the rotary kiln body 2 to rotate.

[0037] like Figure 6 As shown, the base 1 is provided with a notch 11 on its surface; the moving block 46 is provided through the notch 11; and the supporting pulley 57 is provided with two groups;

[0038] During operation, two sets of second meshing belts 22 are provided on the rotary kiln body 2 and are engaged with the two sets of supporting pulleys 57 at the bottom.

[0039] like Figure 1 and Figure 2 As shown, the bottom of the base 1 is fixedly connected to a supporting leg 3; the bottom of the supporting leg 3 is fixedly connected to a rubber pad 31;

[0040] During operation, the rotary kiln body 2 will generate a certain amount of shaking when rotating. The support legs 3 can alleviate the shaking of the base 1, and the rubber pads 31 can prevent slipping during shaking.

[0041] Working principle of the present utility model: In the prior art, based on the current rotary kiln, a large number of electric devices are combined when it is in operation. When these electric devices drive the rotary kiln to rotate, the rotary kiln will generate a certain vibration, thereby causing an offset between the rotary kiln and the bracket, and even causing the rotary kiln to fall over, causing harm to the surrounding staff. In order to prevent such incidents from happening, first, the driving motor 52 is used to drive the crown gear 42 to rotate, and when rotating, the transmission gear 44 drives the two sets of transmission screws 43 to rotate. Then, according to the size of the rotary kiln body 2, the transmission screw 43 is used to adjust the distance between the two sets of moving blocks 46, and the distance must be larger than the rotary kiln body 2. After the adjustment is completed, the rotary kiln body 2 is placed on the base 1, and then the position of the rotary kiln body 2 is adjusted so that the first meshing belt 21 on the rotary kiln body 2 and the limiting pulley 462 are on the same horizontal plane. After the adjustment is completed, the transmission screw 43 is driven to rotate again, so that the moving block 46 drives the limiting column 461 close to the rotary kiln body 2, and the limiting pulley 462 is clamped on the first meshing belt 21. By clamping the limiting pulley 462 inside the first meshing belt 21, the rotary kiln body 2 can be prevented from offsetting during rotation. At the same time, the rotary kiln body 2 can be limited by the limiting columns 461 arranged around it to prevent the rotary kiln body 2 from tipping over during rotation.

[0042] The rotary kiln is driven by the driving component 5. When the rotary kiln body 2 is placed on the base 1, it is driven and supported by the driving component 5 on the base 1. The surface of the rotary kiln body 2 is also fixed with the second meshing belt 22. The supporting pulley 57 on the base 1 is clamped on the second meshing belt 22, supported by the supporting pulley 57 and the supporting plate 54, and supported on both sides by components such as the limit column 461. The second meshing belt 22 can also prevent the rotary kiln body 2 from shifting.

[0043] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
