Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete mixing, and more specifically, to a concrete mixing device. Background Art
[0002] The concrete mixing device is one of the indispensable equipment in the construction project. Its main function is to mix cement, sand, gravel, water and other raw materials in a certain proportion to prepare concrete with uniform quality and excellent performance. In order to meet different construction environments and process requirements, the concrete mixing device usually needs to have a certain degree of flexibility and maneuverability. Among them, realizing vertical and lateral rotation is one of the important functions of the concrete mixing device, which can facilitate the discharge and pouring of concrete. However, the existing concrete mixing device has some shortcomings in vertical rotation, which is mainly reflected in the insufficient limiting capacity in the vertical direction, resulting in certain axial instability and safety hazards in the operation of the device.
[0003] When the existing concrete mixing device rotates vertically, it mainly relies on bearings and supporting structures to achieve vertical limit and stability of the device. However, due to the heavy weight of the device itself, coupled with the vibration and impact force generated during mixing, it is easy to cause deformation, wear or damage to the bearings and supporting structures. Once the vertical limit capacity decreases, the concrete mixing device may appear unstable, such as up and down movement, tilt or deviation, which not only affects the mixing quality and discharging effect of concrete, but also may cause safety accidents and threaten the personal safety of operators.

[0030] In this embodiment, when stirring is required, the belt 17 and the driven wheel 15 can be driven to rotate by rotating the motor 16, and then the driven wheel 15 drives the driving wheel 13 and the lateral wheel 14 to rotate, thereby ensuring the rotation of the mixing barrel 5. Since the center rod 6 is rotatably connected to the bottom frame 3, and the bottom plate 4 is attached to the bottom frame 3, the center rod 6 can be more stably limited, and the positioning of the mixing barrel 5 and the center rod 6 is guaranteed under the action of multiple reinforcing rods 7, thereby ensuring the safety of positioning, and then stirring is carried out by the stirring blade 8. When stirring, the mixing barrel 5 can be placed in a vertical state by rotating the handle 12, and then the clamping block 10 is clamped in the clamping groove 11, thereby ensuring the stability of stirring. When it is necessary to pour out the concrete, the mixing barrel 5 is driven to rotate by the handle 12, thereby completing the stirring process.
[0031] See also Figure 1As an implementation method of a concrete mixing device for a driving mechanism: the driving mechanism includes a driving wheel 13 and a lateral wheel 14, the lateral wheel 14 is coaxially mounted on the side wall of the mixing barrel 5, the driving wheel 13 is rotatably connected to the support frame 1 and the bottom frame 3, the driving wheel 13 is meshed with the lateral wheel 14, a driven wheel 15 is provided on the driving wheel 13, a motor 16 is fixedly provided on the support frame 1, a belt 17 is meshed on the protruding end of the motor 16, the other end of the belt 17 is meshed on the driven wheel 15, and a threaded belt 15 is provided on the motor 16. There is a wire clamping tube 18, on which a threaded tube 19 is threaded. The cable passes through the wire clamping tube 18 and the threaded tube 19 and is electrically connected to the motor 16 and the external power supply equipment. A plurality of reducing blocks 20 are equidistantly arranged on the inner wall of the wire clamping tube 18, and each reducing block 20 is slidably provided with a wire clamping block 21, which abuts against the cable. A receiving sleeve 22 is abutted on the threaded tube 19, and the receiving sleeve 22 presses on the wire clamping block 21. A return spring 23 is provided on the inner wall of the wire clamping tube 18, and the return spring 23 abuts against the receiving sleeve 22.
[0032] More specifically, since the rotation of the motor 16 needs to be powered by a cable, the cable needs to be fixed. By rotating the threaded tube 19, it can be pressed against the receiving sleeve 22, and then the multiple wire clamping blocks 21 can slide along the reducing block 20, so that the multiple wire clamping blocks 21 can contract with each other, so that the wire clamping blocks 21 can be pressed against the cable, thereby ensuring the fixation of the cable, thereby improving the safety of use.

Since the center rod 6 is rotatably connected to the bottom frame 3, and the bottom plate 4 is attached to the bottom frame 3, the center rod 6 can be more stably limited, and the positioning of the mixing barrel 5 and the center rod 6 is guaranteed under the action of multiple reinforcing rods 7, thereby ensuring the safety of positioning, and then stirring is carried out through the stirring blade 8. When stirring, the mixing barrel 5 can be in a vertical state by rotating the handle 12, and then the block 10 is clamped in the clamping groove 11, thereby ensuring the stability of stirring. When the concrete needs to be poured out, the mixing barrel 5 is driven to rotate by the handle 12, thereby completing the stirring process.
[0034] Since the rotation of the motor 16 needs to be powered by a cable, the cable needs to be fixed. By rotating the threaded tube 19, it can be pressed against the receiving sleeve 22, and then the multiple wire clamping blocks 21 can slide along the reducing block 20, so that the multiple wire clamping blocks 21 can contract with each other, so that the wire clamping blocks 21 can be pressed against the cable, thereby ensuring the fixation of the cable, thereby improving the safety of use.
