Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering equipment, in particular to a concrete mixing device. Background Art
[0002] Construction sites require large quantities of concrete mortar. Large mixers or truck mixers are often used for larger quantities, but manual mixing is often used for smaller-scale applications. This process is time-consuming, wastes construction time, and produces poor results.
[0003] The Chinese utility model patent No. 202322162791.5 discloses a masonry mortar mixing device for construction projects, which can use a motor to drive a stirring rod to stir the concrete mortar in the mixing drum. Due to the high viscosity and poor fluidity of the mortar, the stirring rod used in the above patent has a small stirring range and it takes a long time to mix the concrete mortar to the ideal state. Utility Model Content
[0004] The utility model provides a concrete mixing device, which can quickly achieve full mixing of concrete mortar.
[0005] The technical solution adopted by this utility model is:
[0006] A concrete mixing device includes a support, a mixing drum, a rotating stirring rod, and a fixed stirring rod. The mixing drum is vertically arranged and rotatably connected to the support. The rotating stirring rod and the fixed stirring rod are both disposed within the mixing drum and fixedly connected to the mixing drum. The fixed stirring rod is stationary relative to the support. The fixed stirring rod is stationary, while the rotating stirring rod is rotatable. In other words, the rotating stirring rod and the fixed stirring rod move relative to each other, thereby fully mixing the concrete mortar.
[0007] Preferably, there are multiple rotating stirring rods and multiple fixed stirring rods, and the rotating stirring rods and the fixed stirring rods are arranged alternately. Multiple rotating stirring rods and multiple fixed stirring rods can make stirring more efficient.
[0008] Preferably, the rotating stirring rod and the fixed stirring rod are both arranged vertically. The vertical arrangement facilitates the connection and separation of the fixed stirring rod and the stirring barrel, and is also convenient for feeding materials from above the stirring barrel.
[0009] Preferably, the plurality of rotating stirring rods are connected by a rotating base, and the rotating base is detachably connected to the mixing barrel. The rotating base increases the strength of the rotating stirring rods. Since the concrete mixing resistance is large, the strength of the rotating stirring rods needs to be improved.
[0010] Preferably, a stop block is provided in the mixing barrel, and the rotating base and / or the rotating stirring rod are engaged with the stop block. The rotating base is detachable, which is convenient for rinsing and cleaning the mixing barrel, and the engaging method can drive the rotating stirring rod to rotate together when the mixing barrel is driven to rotate.
[0011] Preferably, the mixing drum is provided with fixing holes, and the rotating base and / or rotating stirring rods are connected to the fixing holes via screws. The fixing holes serve to limit the vertical position of the rotating stirring rods, preventing them from moving upward and leaving the mixing drum. Since the rotating stirring rods are not subject to upward forces, the screw connection is sufficient to achieve a fixed effect. The outermost rotating stirring rods are tightly attached to the inner wall of the mixing drum, ensuring that all concrete mortars in the mixing drum are within the mixing range, resulting in a more consistent mixing effect for all mortars.
[0012] Preferably, a stirring frame is further included, the fixed stirring rod is arranged on the stirring frame, the top of the stirring barrel is open, and the fixed stirring rod extends from the top of the stirring barrel into the stirring barrel. The stirring frame can be in the form of a gantry or a cantilever beam, and is used to fix the fixed stirring rod. Boring can be directly dropped from the top of the stirring barrel.
[0013] Preferably, the bottom surface of the mixing drum is conical, with a drive wheel coaxial with the drum installed on the bottom. The drive wheel is connected to a transmission device, with the center of the drive wheel serving as a discharge port. The conical surface facilitates gravity-driven discharge of concrete mortar from the central discharge port. The discharge port can be closed with a snap-on lid during mixing and opened to discharge after mixing is complete. The drive wheel and transmission device can be a sprocket and chain, or a pulley and belt.
[0014] The utility model has the following beneficial effects:
[0015] 1. The utility model can stir concrete mortar quickly and evenly through the interlaced relative movement of the rotating stirring rod and the fixed stirring rod, thereby improving the stirring efficiency and stirring effect.
[0016] 2. The rotating stirring rod is detachable for easy cleaning.
[0017] 3. The top of the mixing barrel is open, which is convenient for feeding and discharging at the bottom, and the setting of the discharge port does not affect the external power source. BRIEF DESCRIPTION OF THE DRAWINGS
