Description

Concrete mixer and ready-mixed concrete manufacturing device with the same

The present invention relates to a concrete mixer and a ready-mixed concrete manufacturing apparatus having the concrete mixer.

Conventional ready-mixed concrete is manufactured from a ready-mixed concrete manufacturing apparatus equipped with a ready-mixed concrete manufacturing apparatus. In the ready-mixed concrete manufacturing apparatus, a concrete mixer is used (Japanese Patent Laid-Open No. 2008-212888). The concrete mixer is used to mix the gravel as a coarse aggregate, the sand as a fine aggregate, concrete, water and a mixture of materials M.

As shown in Fig. 11, it is a conventional internal structure of a concrete mixer. The conventional concrete mixer 50 has a mixer body 51 and two kneading shafts 52, 53. The kneading shafts 52, 53 are rotatably disposed in the mixer body 51, and the kneading shafts 52, 53 are provided with a plurality of paddles. 54. The paddles 54 are used to knead the above-mentioned materials M. Each of the paddles 54 is composed of an arm body 55 and a plate body 56. Each of the arm bodies 55 is connected to each of the kneading shafts 52 and 53 respectively. The plate body 56 is attached to the other end of the arm body 55 and the kneading shafts 52, 53.

Each of the plates 56 is adjacent to each other, and each of the plates 56 is connected to each other to form a spiral strip shape, so that each of the plates 56 surrounds each of the kneading shafts 52 and 53 and is disposed outside the mixer body 51. There is a motor 57, 58 for rotating the kneading shafts 52, 53.

When the conventional concrete mixer 50 is actuated, each of the materials M is put into the mixer body 51, and the kneading shafts 52, 53 are driven by the motors 57, 58 to rotate in the circumferential direction, and are mixed by the plate 56. Each of the materials M, the plate body 56 of the concrete mixer 50 is arranged in a belt shape, so that the kneaded material is moved in the mixer body 51 by the plate body 56 in a smooth and short time.

Usually, the viscosity of the material M is small shortly after the start of the kneading; when the material M is stirred and the kneading time passes to a certain extent, the material M produces a viscous, highly viscous kneaded material that cannot be configured. The strip-shaped plate body 56 is lifted up. The kneaded material having a higher viscosity can only move along the side surface of the plate body 56, so that the conventional concrete mixer 50 has a problem that the shearing effect on the kneaded material having high viscosity is inferior.

Further, when the material M is conveyed along the side faces of the plate bodies 56, as shown in Fig. 12, the material M becomes easily rolled at the bottom of the mixer body 51 and the side surface of the plate body 56. When the rolling distance of the material M becomes longer, the volume of the material M expands and becomes larger as the outer surface continues to adhere to other materials due to rolling, thereby generating a so-called "holding ball", which is a ready-mixed concrete quality. The reason for the decrease. Therefore, in the concrete mixer 50, the rolling of the material M must be suppressed as much as possible.

The space in which the valley Q moves, that is, the space near the valley Q is irregular.

Fig. 9 is a schematic view showing the movement of the material in the valley portion Q, and when the first stirring paddle 24, the second agitating paddle 25, and the third agitating paddle 26 are rotated, the space near the valley portion Q Irregular changes, so the material in the space moves along the first plate 30 (refer to M1 of FIG. 9) or moves across the valley Q of the first plate 30 (refer to M2 of FIG. 9). ), and in Figure 9, For convenience of explanation, the state of movement of the material is schematically indicated, and other mechanism members are partially omitted.

In the configuration of the conventional concrete mixer 50, as shown in FIG. 12, the plate body 56 is disposed in a belt shape, and in the concrete mixer 50, the paddle 54 is viewed from the side of the drive motor 57 when rotated. The trajectory of the side surface of the plate body 56 is circular (refer to the broken line L1 of FIG. 12), and therefore, the material mainly moves only along the side surface of the plate body 56.

On the other hand, in the bottom portion U (see FIG. 8) of the mixer body 10, the space in the vicinity of the valley portion Q changes irregularly with time, and therefore, the material also corresponds to the space more irregularly. Moved.

Shortly after the start of the kneading, the material is less viscous and stirred, and then after a certain period of time after the kneading, the material is sheared when the material is viscous, and in the concrete mixer 8, near the valley Q The space system changes irregularly, so the mixing and cutting of the kneaded material can be performed at the same time.

In the configuration of the conventional concrete mixer 50, the material rolls along the side of the plate 56, and sometimes a "cage" is generated. In the concrete mixer 8 of the present invention, the space near the valley Q is met. The irregularity of the passage of time causes the material to move, so that the concrete mixer 8 can greatly suppress the occurrence of "balls".

Since the size of the first plate body 30 of the concrete mixer 8 is larger than that of the conventional plate body 56. Therefore, the number of the first plate body 30 of the present invention is smaller than that of the conventional plate body 56, so that the number of the arm bodies 29 of the concrete mixer 8 is smaller than that of the conventional arm body 55, thereby The amount of material between the arm body 29 and the arm body 29 is increased, that is, the "material throughput" can be improved.

The second agitating paddle 25 and the first shearing paddle 27 of the concrete mixer 8 are disposed on opposite sides of the shaft of the first kneading shaft 11, and the auxiliary agitating paddle 34 of the concrete agitator 8 The second shearing paddles 35 are also disposed on opposite sides of the shaft of the first kneading shaft 11, whereby the concrete mixer 8 can alternately stir and shear the kneaded material to improve the performance of the kneading.

The material in the vicinity of the first paddle module 21 is agitated by the second agitating paddle 25, and the material is immediately cut by the first shearing paddle 27 after the first kneading shaft 11 is rotated half a turn. Further, the material in the vicinity of the second paddle module 22 is agitated by the auxiliary agitating paddle 34, and the material is immediately cut by the second shearing paddle 35 after the first kneading shaft 11 is rotated half a turn. Broken.
