DETAILED DESCRIPTION

[0023] In order to better understand the purpose, structure and function of the utility model, the utility model is described clearly and completely in combination with the drawings.

[0024] For example, Figs. 1-3The mixer shown includes: a mounting frame 1, a mixing drum 3, a drive unit, and a dust collection device. The mounting frame 1 supports the mixing drum 3, the drive unit, and the dust collection device to facilitate smooth mixing operations. The mixing drum 3 contains a mixing device; the specific structure of the mixing device is prior art and will not be described in detail here. The drive unit drives the mixing drum 3 to rotate, thereby mixing the materials inside the mixing drum 3 into a slurry. The dust collection device absorbs dust from the opening of the mixing drum 3, preventing dust from escaping and reducing environmental pollution.

[0025] In this embodiment, the stirring cylinder 3 is horizontally oriented, extending front to back, and is rotatably connected to the mounting frame 1. Further, the upper part of the mounting frame 1 is provided with a U-shaped fixing frame 12. The fixing frame 12 and the mounting frame 1 can be integrally formed or connected by bolts. The fixing frame 12 is made of structural steel. A connecting frame 13 is provided between the two vertical frames of the fixing frame 12, such as... Fig. 2 As shown, the connecting frame 13 is located at the rear of the stirring drum 3, and its middle part is rotatably connected to the stirring drum 3. For example, a bearing is installed at the position of the stirring drum 3 and the connecting frame 13 to realize the rotatable connection between the two. The connecting frame 13 and the fixed frame 12 cooperate to support the stirring drum 3. When the driving device drives the stirring drum 3 to rotate, since the rear side of the stirring drum 3 is rotatably connected to the connecting frame 13, the stirring drum 3 can rotate relative to the mounting frame 1.

[0026] A drive unit, mounted on the mounting frame 1, is used to drive the stirring drum 3 to rotate. It includes a motor 4, a gear 5, and a gear ring 6. The output shaft of the motor 4 is connected to the gear 5, and the gear 5 meshes with the gear ring 6. The gear ring 6 is fitted onto the outer wall of the stirring drum 3 and is coaxial with the stirring drum 3. When the motor 4 rotates, it drives the gear 5 to rotate, which in turn drives the gear ring 6 meshing with the gear 5 to rotate. The gear ring 6 has a small clearance fit with the stirring drum 3, causing the stirring drum 3 to rotate accordingly, mixing and stirring the materials inside into a slurry. The connection between the motor 4 and the gear 5 can be supplemented with transmission components such as a conveyor belt or chain, depending on the actual application. Furthermore, the drive unit is externally protected by a protective shell 15, specifically a protective shell 15 is installed on the outside of the motor 4 to protect it.

[0027] The dust collection device includes a dust collection ring 7 and a dust collection box 8 mounted on the mounting frame 1. A negative pressure fan is installed inside the dust collection box 8. The dust collection ring 7 is located outside the opening of the mixing drum 3 and is connected to the dust collection box 8 via a dust collection pipe 9. The dust collection ring 7 absorbs dust at the opening of the drum. Specifically, the lower part of the dust collection ring 7 is connected to the mounting frame 1 via a support frame 14. The dust collection ring 7 is wider at the front and narrower at the back, used to cooperate with the dust collection box 8 to absorb dust at the opening of the mixing drum 3. Furthermore, in this embodiment, the dust collection ring 7 has multiple suction ports, all of which are connected to the dust collection box 8 via the dust collection pipe 9.

[0028] The rear side support leg 2 of the mounting frame 1 can be extended and retracted, so that the barrel mouth of the stirring barrel 3 faces upward when stirring to prevent the slurry in the stirring barrel 3 from flowing out, and the barrel mouth of the stirring barrel 3 faces downward when discharging to facilitate pouring out the slurry in the stirring barrel 3. Specifically, a hydraulic rod 10 is arranged on the rear side support leg 2 of the mounting frame 1, which is used to adjust the length of the rear side support leg 2 to adjust the angle of the stirring barrel 3. A switch electrically connected to the control part of the hydraulic rod 10 can be arranged on the protective shell 15, and the extension and retraction of the rear side support leg 2 can be realized by operating the switch. When the rear side support leg 2 is extended or retracted, the mounting frame 1 is inclined. In order to increase the stability of the front side support leg 2, the left and right sides of the front side support leg 2 of the mounting frame 1 are both provided with a castor 11. That is, no matter how the length of the rear side support leg 2 changes, the front side support leg 2 can always be tangent to the ground through the castor 11 to support the whole.
