SUMMERY OF THE UTILITY MODEL

The utility model provides a mixer for processing concrete, aiming at the technical problems in the prior art.

The technical scheme for solving the technical problems is as follows:

the mixer for processing the concrete comprises a mixing drum and a mounting frame for mounting the mixing drum; the mixing drum comprises an inner drum, an outer drum and a connecting sheet; the inner cylinder and the outer cylinder are coaxially arranged and are connected through a plurality of connecting sheets; the connecting sheets are uniformly distributed outside the inner cylinder at intervals, and porous elastic materials are filled between the adjacent connecting sheets.

The utility model has the beneficial effects that: when the stirring machine is used for stirring, stone materials such as cement are placed on the inner barrel, when the motor is driven, the outer barrel starts to rotate and drives the inner barrel inside through the connecting sheet to rotate simultaneously, and the stirring barrel is of a double-layer structure of the inner barrel and the outer barrel, so that noise generated by friction of the materials such as the cement inside and the barrel of the rigid structure is absorbed by the filled porous elastic material, and the noise generated in the stirring process can be greatly reduced.

On the basis of the technical scheme, the utility model can be further improved as follows.

Further, the connecting sheet is made of a flexible material.

Furthermore, two ends of the connecting sheet form connecting holes by extending and bending; the wall of the inner cylinder and the wall of the outer cylinder are provided with connecting lugs; the connecting holes are movably connected on the connecting lugs by penetrating through the shaft lever.

Further, the porous elastic material is sound-absorbing cotton.

The beneficial effect of adopting the further scheme is that: based on the toughness characteristic of the connecting sheet, the connecting sheet can be bent and deformed in the rotating and stirring process of the stirring cylinder, so that the rotation of the inner cylinder is buffered, the whole stirring cylinder tends to be balanced, and the problems of accelerated wear and aging of parts of the stirring cylinder caused by the collision of stone and the stirring cylinder in the stirring process are solved; the sound-absorbing cotton is selected as the porous elastic material, so that the requirements on the functions of sound absorption and noise reduction can be met, and meanwhile, the sound-absorbing cotton also has excellent elasticity and can adapt to the shape change of the accommodating cavity caused by the elastic deformation of the connecting sheet; the structural arrangement of connection piece is in order to further improve the degree of freedom of connection piece, avoids fixed connection's such as welding mode to lead to the connection piece because the swing back and forth leads to the tie point ageing even fracture.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

Example 1

As shown in fig. 1 to 3, the mixer for concrete processing according to the present embodiment includes a mixing drum 10 and a mounting bracket 20 for mounting the mixing drum 10. A motor (not shown) for driving the agitating drum 10 to rotate is mounted on the mounting bracket 20. The mixing drum 10 is driven by a motor to rotate, so that stones such as cement are mixed by the mixing blades arranged in the mixing drum to obtain concrete.

The mixing drum 10 comprises an inner drum 11, an outer drum 12 and a connecting sheet 13. The inner cylinder 11 and the outer cylinder 12 are coaxially arranged, and the inner cylinder 11 and the outer cylinder 12 are connected through a connecting sheet 13. The connecting pieces 13 are uniformly distributed at intervals outside the inner cylinder 11, and a porous elastic material 14 is filled between the adjacent connecting pieces 13.

Based on above-mentioned churn 10 structure, when the stirring, building stones such as cement are placed to inner tube 11, and when motor drive, urceolus 12 begins to rotate and drives inside inner tube 11 through connection piece 13 and rotate simultaneously, because churn 10 is the bilayer structure of interior outer bucket for the noise that the barrel friction of materials such as inside cement and rigid construction produced is absorbed by porous elastic material 14 that fills, thereby can greatly reduced the noise that the stirring in-process produced.

In addition, in order to further improve the vibration damping effect of the mixer during the mixing process, the connecting piece 13 is made of a ductile material such as mild steel (mild steel). Based on the toughness characteristic of the connecting sheet 13, the connecting sheet 13 can be bent and deformed in the rotating and stirring process of the stirring cylinder 10, so that the rotation of the inner cylinder 11 is buffered, the whole stirring cylinder 10 tends to be balanced, and parts of the stirring cylinder 10, such as gears and the like, caused by collision of stone materials and the stirring cylinder in the stirring process are prevented from being abraded and aged in an accelerated manner, particularly in a driving structure.

The porous elastic material 14 may be selected from sound absorbing cotton and foam glass. The sound-absorbing cotton is selected as the porous elastic material 14, so that the functional requirements of sound absorption and noise reduction can be met, the sound-absorbing cotton also has excellent elasticity, and the shape change of the accommodating cavity caused by the elastic deformation of the connecting sheet 13 can be adapted.

Both ends of the connecting sheet 13 are formed into connecting holes 17 by extending and bending; the cylinder walls of the inner cylinder 11 and the outer cylinder 12 are provided with connecting lugs 15; the connecting hole 17 is movably connected on the connecting lug 15 by a penetrating shaft lever. The arrangement of the structure is to further improve the degree of freedom of the connecting sheet 13, and avoid the connecting sheet 13 from aging or even breaking due to the back-and-forth swing caused by the fixed connection modes such as welding and the like. And the connecting holes 17 on the connecting sheet 13 are integrally formed, so that the strength of the connecting sheet 13 and the connecting strength of the connecting points are greatly improved.

It should be noted that, in the above embodiments, all the terms "fixedly connected", "fastened" or expressions having similar meanings, which are not specifically or explicitly described, may be understood as a manner of fixing by welding or fastening by bolts.

The mechanisms, components and parts of the utility model which are not described in the specific structure are the existing structures existing in the prior art and can be directly purchased from the market.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
