Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, and particularly relates to a special mixer for preparing recycled concrete. Background Technique

[0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water to prepare concrete mixture. Recycled concrete is an environmentally friendly and sustainable building material. By processing and reusing waste concrete, resource consumption and environmental pollution can be effectively reduced. In the process of preparing recycled concrete, a mixer is also required.

[0003] Due to the viscosity of concrete itself, there is easily residual concrete inside the mixer. Generally, water flushing is used. However, for a tilting drum concrete mixer, since the discharge port is blocked by the discharge blade and the feeding port is blocked by the feeding mechanism, it is inconvenient to clean the inside. If it is not flushed cleanly, it is not conducive to the next mixing. Therefore, the flushing time is long and the efficiency is low. If a large amount of water is used for flushing, the residual concrete will be unusable, which is a waste of resources. In addition, since the mixer discharges by rotation, during the discharging process, concrete is easily spilled on the ground, which is likely to cause ground pollution. In view of this, we propose a special mixer for preparing recycled concrete. Content of the Utility Model

[0029] Please refer to Figures 1-4 , the present utility model details the above technical solutions through the following embodiments:

[0030] A special mixer for preparing recycled concrete, comprising:

[0031] Support 1, the support 1 includes a discharge port support 11, a discharge hopper 12 is welded to the top of the discharge port support 11, a stirring barrel support 13 is welded behind the discharge port support 11, a feed port support 14 is welded behind the stirring barrel support 13, and a feed hopper 15 is welded to the top of the feed port support 14.

[0032] The support 1 is used to provide support for the device.

[0033] Drive assembly 2, the drive assembly 2 is installed on the right side of the stirring barrel support 13. The drive assembly 2 includes a first power source 21, the first power source 21 is installed on the right side of the stirring barrel support 13 by bolts, a drive gear 22 is fixedly connected to the top of the first power source 21, a transmission gear 23 is meshed on the left side of the drive gear 22, a transmission shaft 24 passes through the middle of the transmission gear 23, and the transmission shaft 24 is rotatably installed on the top right side of the stirring barrel support 13 through a transmission shaft support 25. Drive friction wheels 26 are fixedly connected to the head and tail of the right transmission shaft 24, and a transmission shaft 24 is also rotatably installed on the top left side of the stirring barrel support 13 through a transmission shaft support 25. Driven friction wheels 27 are fixedly connected to the head and tail of the left transmission shaft 24.

[0034] The drive assembly 2 is used to provide power for the device. The first power source 21 is a motor that can change the rotation direction. After the first power source 21 is powered on and started, it will drive the drive gear 22 to rotate. Since the drive gear 22 and the transmission gear 23 are meshed, the transmission gear 23 will also rotate accordingly. The drive friction wheels 26 fixed to the same transmission shaft 24 as the transmission gear 23 will also rotate.

[0035] It also includes:

[0036] Stirring barrel 3, the stirring barrel 3 is connected to the drive assembly 2. The stirring barrel 3 is installed between the drive friction wheels 26 and the driven friction wheels 27. The stirring barrel 3 includes a discharge cone 31, discharge blades 32 are welded inside the discharge cone 31, a barrel body 33 is welded to the left side of the discharge cone 31, raceways 34 are welded to the outer sides of the left and right ends of the barrel body 33, the raceways 34 are connected to the drive friction wheels 26 and the driven friction wheels 27, a large gear ring 35 is welded to the tail of the barrel body 33 and on the right side of the raceway 34, the large gear ring 35 is meshed with the transmission gear 23, stirring blades 36 are welded inside the barrel body 33, and a feed cone 37 is welded to the left side of the barrel body 33.

[0037] The stirring barrel 3 is driven by the drive assembly 2 to process and stir the materials. When the transmission gear 23 and the drive friction wheels 26 rotate, they will drive the large gear ring 35 and the raceways 34 to rotate, thereby driving the stirring barrel 3 to rotate. The rotation of the stirring barrel 3 will drive the stirring blades 36 welded inside the barrel body 33 to rotate, and further stir the materials inside the barrel body 33.

[0038] The observation component is located in the middle of the barrel body 33. The observation component includes an observation port 41. The observation port 41 is located in the middle of the barrel body 33 and on the right side of the large gear ring 35. An observation port guide rail 42 is welded outside the observation port 41. A baffle 43 is slidably installed inside the observation port guide rail 42. Four T-shaped screws 44 are threadedly connected to the observation port guide rail 42. The top of the T-shaped screw 44 passes through the observation port guide rail 42 and abuts against the surface of the baffle 43. A handle 45 is screwed to the middle of the baffle 43.

[0039] The observation component is used to observe the inside of the mixing barrel 3 after the device stops, which is convenient for cleaning the inside of the mixing barrel 3. Since the T-shaped screw 44 and the observation port guide rail 42 are threadedly connected, when the T-shaped screw 44 rotates, it will move perpendicular to the observation port guide rail 42. When rotating clockwise, it will move perpendicular to the observation port guide rail 42 towards the barrel body 33, thereby pressing the baffle 43 against the barrel body 33 to prevent the internal material from flowing out. When the T-shaped screw 44 is rotated counterclockwise, the T-shaped screw 44 will move away from the barrel body 33. At this time, the baffle 43 can be removed from the observation port guide rail 42.

[0040] In this embodiment, when the operator uses this device, first inject raw materials from the feed hopper 15 into the feed cone 37, and then start the first power source 21 to make the motor rotate clockwise, so that the mixing barrel 3 rotates clockwise to stir the internal materials. After stirring evenly, reverse the motor to make the mixing barrel 3 rotate counterclockwise, and the materials will flow out of the discharge cone 31 along the discharge blades 32 and then flow out from the discharge hopper 12. When there is no more material flowing out, turn off the first power source 21. After the mixing barrel 3 stops completely, open the baffle 43 to clean the remaining materials inside the barrel body 33. After cleaning, close the baffle 43 and tighten the T-shaped screw 44, and then the second stirring can be carried out.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
