Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a mixer for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials that are made by bonding aggregates into a whole with cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and obtained by mixing. It is also called ordinary concrete and is widely used in civil engineering.

[0003] After searching, Chinese patent CN220807955U was found and announced a concrete mixing mechanism. Most of them are driven by the rotating disk and the through hole through the connecting parts to rotate the rotating disk. During the rotation of the rotating disk, the through hole and the material guide pipe will be misaligned. At this time, the rotating disk will block the material guide pipe, making it impossible for the material guide pipe to discharge materials. When the rotating disk rotates to the point where the through hole is connected to the material guide pipe, the material guide pipe will discharge materials, and this cycle will be repeated, so that intermittent feeding can be performed to avoid excessive addition of materials resulting in a long time for uniform mixing, thereby improving the mixing efficiency of the mixing mechanism. It can be seen that the shell used in this patent is stationary. After long-term mixing of concrete, concrete blocks will adhere to the inner wall of the shell, causing uneven mixing of the concrete mixture, thereby affecting the mixing quality of the concrete. For this reason, it is necessary to swing the shell containing concrete to reduce the adhesion of concrete, so a mixer for concrete production is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a mixer for concrete production, which has the advantage of reducing the adhesion of concrete to the inner wall of the shell.

[0006] The swing assembly includes a driving disk, an outer gear ring, a motor and a gear. The driving disk is rotatably connected to the support plate. The mixing drum is fixedly installed in the driving disk in an oblique manner. The axis of the mixing drum and the axis of the driving disk are no longer in a straight line. The outer gear ring is fixedly installed on the side wall of the driving disk. The motor is fixedly installed on the side wall of the support plate. The gear is fixedly installed on the output shaft of the motor, and the outer gear ring is meshed with the outside of the gear.

[0007] Furthermore, there are two locking covers, and the driving disk is cylindrical in shape, and the driving disk penetrates the supporting plate.

[0008] Furthermore, a material receiving box is placed on the top of the bottom plate and on both sides of the support plate, and a handle is fixedly installed on the outer wall of the material receiving box.

[0009] Furthermore, a limiting assembly for limiting the docking material box is provided on the bottom plate, and the limiting assembly includes a guide bar and a baffle bar, wherein the guide bar is fixedly connected to the top of the bottom plate and located on both sides of the support plate, and the baffle bar is slidably connected to the inside of the guide bar.

[0010] Furthermore, the guide bars and the baffle bars are both in the shape of quadrangular prisms, the baffle bars are used to connect the guide bars on the front and rear sides, and the guide bars and the baffle bars are both in contact with the side walls of the material receiving box.

[0011] Compared with the prior art, the utility model provides a mixer for concrete production, which has the following beneficial effects:

[0012] The mixer for concrete production is provided with a swinging assembly. After the swinging assembly is used, under the external meshing transmission of the gear and the outer gear ring, the motor can drive the driving disk to rotate after starting, so that the mixing drum can be rotated accordingly, so that the mixing drum can be tilted left and right repeatedly, so that the concrete in the mixing drum does not stay in the same area of ​​the inner wall of the mixing drum, thereby reducing the adhesion of concrete to the inner wall of the mixing drum. Moreover, the swinging and tilting of the mixing drum can also make the concrete raw materials collide with each other, thereby increasing the contact area between the concrete raw materials, improving the adequacy of mixing between the concrete raw materials, and ensuring the production quality of concrete.

The outer wall of the material receiving box 6 is fixedly installed with handles, which is convenient for pulling out or placing the material receiving box 6. A limiting assembly 7 for limiting the docking material box 6 is provided on the bottom plate 1. The limiting assembly 7 includes a guide bar 71 and a stop bar 72. The guide bar 71 is fixedly connected to the top of the bottom plate 1 and is located on both sides of the support plate 4. It is used to guide the docking material box 6 so that the material receiving box 6 is located between the guide bars 71 on both sides. The guide bars 71 and the stop bars 72 are both in the shape of quadrangular prisms. The stop bar 72 is slidably connected to the inside of the guide bar 71, so as to avoid the displacement of the material receiving box 6 after being impacted by the falling material during the material receiving process, and play a limiting role. The stop bar 72 is used to connect the guide bars 71 on the front and rear sides, and the guide bars 71 and the stop bars 72 are both in contact with the side walls of the material receiving box 6.

The driving disc 51 is cylindrical in shape. The driving disc 51 penetrates the support plate 4. The mixing drum 2 is fixedly installed in the driving disc 51 in an oblique manner, so that the concrete raw materials can be tilted in the mixing drum 2, reducing the concrete adhesion caused by the concentration of concrete raw materials in the same area. The axis of the mixing drum 2 and the axis of the driving disc 51 are no longer in a straight line.

[0021] In addition, the outer gear ring 52 is fixedly mounted on the side wall of the driving disk 51 and can rotate with the driving disk 51.

Under the meshing of the gear 54 and the outer gear ring 52, the driving disk 51 and the mixing drum 2 are driven to rotate, and the concrete raw materials in the mixing drum 2 gradually collide with each other, thereby increasing the adequacy of the mixing.

[0022] When the present embodiment is in use, the lock cover 3 is opened, concrete raw materials are poured into the mixing drum 2, the gear 54 is started, the gear 54 rotates, and the drive disc 51 and the mixing drum 2 rotate under the transmission of the external meshing of the gear 54 and the outer gear ring 52, driving the concrete raw materials in the mixing drum 2 to collide and mix with each other. After the concrete is produced, the lock cover 3 is opened, the concrete is discharged into the material receiving box 6, the baffle bar 72 is pulled out, and the material receiving box 6 is taken out from between the guide bars 71 on both sides.

After the swinging assembly 5 is used, under the external meshing transmission of the gear 54 and the outer gear ring 52, the motor 53 can drive the driving disc 51 to rotate after being started, so that the mixing drum 2 can rotate accordingly, so that the mixing drum 2 can be repeatedly tilted left and right, so that the concrete in the mixing drum 2 does not stay in the same inner wall area of ​​the mixing drum 2, thereby reducing the adhesion of the concrete to the inner wall of the mixing drum 2. In addition, the swinging and tilting of the mixing drum 2 can also make the concrete raw materials collide with each other, thereby increasing the contact area between the concrete raw materials, improving the adequacy of mixing between the concrete raw materials, and ensuring the production quality of the concrete.
