Description
Technical Field
[0001] The present application relates to the technical field of municipal construction, and in particular to a concrete mixing device used in municipal construction. Background Art
[0002] At present, municipal construction is an important part of municipal activities. It is the execution stage of planning and design. It is the construction of various public facilities and undertakings hosted by the city government according to the overall deployment of municipal planning, such as roads, drainage and bridges. It aims to prosper the urban economy, facilitate the production and living environment of citizens, and promote the development of the city's material and spiritual civilization. The content and scope of municipal construction is dynamically developing. Municipal engineering construction is a traditional concept of municipal construction and is an important part of it.
[0003] In the process of municipal construction, concrete is a commonly used principle, and untreated concrete needs to be mixed. However, the mixing blades and mixing shafts of existing concrete mixers are welded and fixed, and the shape and length of the mixing blades are fixed. When mixing, they can only be stirred in the same plane, and the mixing radius range is fixed, and subsequent control and adjustment cannot be performed. In addition, there is only a single fixed rotation mixing method, so the mixing efficiency is low, the work efficiency is low, and the mixing effect is poor. Utility Model Content
[0004] In order to reflect that the mixing range of concrete can be adjusted, the present application provides a concrete mixing device for municipal construction.
[0005] The present application provides a concrete mixing equipment for municipal construction using the following technical solutions:
[0006] A concrete mixing device for municipal construction comprises a mixing barrel shell and a bracket. When the mixing barrel shell is arranged horizontally, the mixing barrel shell and the bracket are rotatably connected. The rotation axis direction of the mixing barrel shell is along the horizontal direction. A central axis is arranged inside the mixing barrel shell. The central axis is arranged along the horizontal central axis of the mixing barrel shell. The central axis is hollow inside. A slider is slidably connected inside the central axis. The sliding direction of the slider is along the length direction of the central axis. A driving component for driving the sliding block to slide is arranged inside the central axis. A plurality of first stirring rods are fixed on the slider. The plurality of first stirring rods are arranged at intervals along the circumference of the slider. One end of the first stirring rod away from the slider passes through the central axis and abuts against the inner wall of the mixing barrel shell.
[0007] By adopting the above technical solution, the bracket is fixed horizontally on the ground, and the bracket can control the rotation of the mixing barrel shell. During the rotation of the mixing barrel shell, the first stirring rod inside will stir the concrete before construction. The first stirring rod here is different from the conventional fixed stirring rod. The first stirring rod here can slide along the length direction of the central axis under the sliding action of the slider, and combined with the rotation action of the mixing barrel shell itself, stirring is carried out in multiple directions of horizontal and vertical directions and the formed angles, which greatly increases the stirring range of the first stirring rod.
[0008] Optionally, the driving assembly includes a first motor, a gear plate and a connecting rod, the first motor is fixedly connected to the mixing barrel shell, the gear plate is rotatably connected to the central axis, the rotation axis direction of the gear plate is perpendicular to the sliding direction of the slider, the first motor and the gear plate are coaxially fixed, one end of the connecting rod is hinged to the slider, and the other end is hinged to the non-center point of the gear plate.
[0009] By adopting the above technical solution, the first motor drives the gear plate to rotate. Since the connecting rod on the gear plate is hinged at a non-center position, the rotation of the gear plate will drive the connecting rod to move toward or away from the center of the gear plate. In addition, the connecting rod is hinged to the slider, so the connecting rod can drive the slider to move in a direction close to or away from the gear plate, thereby achieving the purpose of reciprocating motion of the slider.
[0010] Optionally, a first spring is fixed to one end of the first stirring rod close to the inner wall of the stirring barrel shell, and a scraper is fixed to one end of the first spring away from the first stirring rod. The scraper abuts against the inner wall of the stirring barrel shell. When the first stirring rod is stirring, the first spring is in a compressed state.
[0011] By adopting the above technical solution, because the length of the first stirring rod can abut the inner wall of the mixing barrel shell, during stirring, the scraper at the end of the first stirring rod can scrape the inner wall of the mixing barrel shell at any time to prevent concrete material from accumulating on the inner wall of the mixing barrel shell, resulting in insufficient stirring. When pouring, there will also be adhesion, which can easily lead to material waste.
[0012] Optionally, a plurality of second stirring rods are fixed on the slider, and the plurality of second stirring rods are arranged at intervals along the circumference of the slider, and the circumferential paths of the second stirring rods are parallel to the circumferential paths of the first stirring rods and do not overlap, one end of the second stirring rod away from the slider passes through the central axis, and the length of the second stirring rod is less than the length of the first stirring rod.
[0013] By adopting the above technical solution, because the length of the second stirring rod is much shorter than that of the first stirring rod, when mixing concrete, the concrete close to the central axis can be mixed at the same time, preventing the concrete close to the central axis from piling up and causing insufficient mixing.
[0014] Optionally, multiple protective shells are slidably connected to the side walls of the central axis, and the sliding direction of the protective shells is parallel to the length direction of the central axis. The multiple protective shells match the positions of the first stirring rod and the second stirring rod passing through the central axis, and the protective shells are respectively fixedly connected to the first stirring rod and the second stirring rod at corresponding positions.
[0015] By adopting the above technical solution, the positions where the first stirring rod and the second stirring rod pass through the side wall of the central axis are likely to leave sliding holes. If the holes are not sealed, concrete raw materials are likely to enter the interior of the central axis. The protective shell covers the position of the holes and is fixedly connected to the first stirring rod or the second stirring rod. During the sliding process of the first stirring rod and the second stirring rod, the protective shell always covers the holes, thereby preventing concrete raw materials from entering the interior of the central axis.
[0016] Optionally, the diameter of one end of the central axis close to the bottom of the mixing barrel shell gradually increases, that is, the diameter of one end of the central axis away from the barrel bottom is smaller than the diameter of one end close to the barrel bottom.
[0017] By adopting the above technical solution, the diameter of the central axis becomes larger at the position of the mixing barrel shell near the bottom of the barrel, so that the central axis is funnel-shaped when close to the bottom of the barrel. This can prevent concrete from accumulating at the bottom of the barrel inside the mixing barrel, resulting in insufficient mixing. At the same time, it can prevent concrete from accumulating at the bottom of the barrel when the concrete material is poured, resulting in waste of materials. In addition, the range of motion of the connecting rod can be increased.
[0018] Optionally, a shock absorbing assembly is provided on the bracket, and the shock absorbing assembly includes a shock absorbing spring and a damper. The shock absorbing assembly disconnects the bracket, and the damper penetrates the shock absorbing spring and is arranged along a setting direction parallel to the bracket. Both ends of the damper are respectively fixedly connected to the bracket, and both ends of the shock absorbing spring are also respectively fixedly connected to the bracket.
[0019] By adopting the above technical solution, the shock-absorbing component on the bracket can increase the shock-absorbing effect of the bracket when the mixing barrel rotates and mixes, thereby increasing the overall shock-absorbing effect of the mixing barrel and increasing the service life of the overall device.
[0020] Optionally, one end of the scraper close to the inner wall of the mixing barrel shell is provided with an arc.
[0021] By adopting the above technical solution, the scraper is used to scrape off the materials adhering to the inner wall of the mixing barrel shell. The arc can prevent the mixing barrel shell from being worn, thereby increasing the service life of the device.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The driving assembly can drive the slide to slide along the length direction of the central axis, thereby driving the first stirring rod to slide along the length direction of the central axis. Combined with the rotation of the stirring barrel shell, the purpose of increasing the stirring range of the first stirring rod can be achieved;
[0024] 2. The second stirring rod can stir the concrete near the central axis while the first stirring rod is stirring, which can stir the concrete more fully and prevent the concrete from piling up at the central axis. BRIEF DESCRIPTION OF THE DRAWINGS
