Technical Field

[0001] This utility model belongs to the field of engineering equipment technology, and in particular relates to a mixing drum for a mixer truck and a mixer truck. Background Technology

[0002] A concrete mixer truck is a specialized vehicle used in the construction industry for transporting and mixing concrete. It is a device used to mix raw materials and water to form mud-like materials. The mixing drum is the main part of the concrete mixer truck, which mainly consists of a drum body and internal mixing blades. The mixing blades are used to mix the materials.

[0003] During concrete transportation, the mixing of concrete by the existing mixing blades in the mixing tank can lead to insufficient mixing at the beginning and end of the concrete discharge process. This results in stones falling out first during discharge, causing an excess of stones to be visible. Therefore, it is necessary to provide a mixing drum for the concrete mixer truck to solve the above problems. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Example 1 Reference Figure 1 and Figure 2 This embodiment provides a mixing drum for a mixer truck, including a drum body 1 and a mixing mechanism 2. One end of the drum body 1 is the feeding end, and the other end is the discharging end. The mixing mechanism 2 is disposed inside the drum body 1 and is used to mix the materials. In use, the materials are placed into the drum body 1, and the mixing mechanism 2 is activated to mix the materials inside the drum body 1, making them more evenly mixed.

[0024] Reference Figure 2 The stirring mechanism 2 includes stirring blades 21, a baffle cone 22, and a feed cone 23. The stirring blades 21 are spirally arranged and coaxially mounted with the cylinder 1, with the sidewalls of the stirring blades 21 fixed to the inner sidewall of the cylinder 1. The stirring blades 21 include multiple first blades 211 and multiple second blades 212, which are alternately welded and fixed. Each first blade 211 and second blade 212 has three evenly spaced vent holes 24, each φ80mm.

[0025] When in use, after the material enters the cylinder 1, the stirring mechanism 2 is started. The stirring blades 21 will stir the material. During the mixing process, air will be mixed in and form bubbles. The vent holes 24 on the stirring blades 21 can provide a channel to allow the bubbles to be smoothly discharged from the stirring cylinder during the stirring process. It can also promote the flow of materials during the stirring process, improve the uniformity of the stirring, and make the stones more evenly mixed.

[0026] Reference Figure 2 and Figure 3The baffle cone 22 is located inside the cylinder 1 near the feed end and in the middle of the stirring blades 21. The baffle cone 22 includes a D-baffle 221, a reinforcing plate 222, a first conical plate 223, and a second conical plate 224. The D-baffle 221 has a symmetrically arranged half-φ145mm flow hole 225 at a distance of 65mm from the edge along its straight section, a half-φ80mm flow hole 225 at the middle of its straight section, and a symmetrically arranged full-size φ145mm flow hole 225 at a distance of 65mm from the edge along its curved section. There are two D-baffles 221, welded together to form a single circular plate, coaxially aligned with the cylinder 1, and located 50mm from the end of the feed cone 23. There are multiple reinforcing plates 222; in this embodiment, there are two, arranged in an "L" shape. Two reinforcing plates 222 are symmetrically arranged on both sides of the two D-baffles 221, and the two ends of the two reinforcing plates 222 are welded and fixed to the D-baffles 221 and the inner wall of the cylinder 1, respectively. There are multiple first conical plates 223, seven in this embodiment, with two φ80mm vent holes 24 spaced apart. There are multiple second conical plates 224, six in this embodiment, with three φ80mm vent holes 24 spaced apart. The first conical plates 223 and the second conical plates 224 are arranged alternately around the two D-baffles 221, and are all fixedly connected to the D-baffles 221 to form an integral cone. The outer wall of the baffle cone 22 is welded and fixed to the stirring blade 21. During welding, the gap between the baffle cone 22 and the stirring blade 21 can be filled with wear-resistant strips. A notch is cut on the side of the baffle cone 22 near the feed end along the spiral direction of the stirring blade 21, with a short side length of 750mm after cutting.

[0027] Reference Figure 2 The feed cone 23 is located inside the cylinder 1 near the discharge end, and a discharge port is formed between the inner surface of the cylinder 1 and the outer surface of the feed cone 23. The feed cone 23 has an opening on one side, which is arc-shaped and faces the feed end. The outer wall of the feed cone 23 is welded and fixed to the stirring blade 21, and multiple φ80mm vent holes 24 are evenly distributed on the feed cone 23.

[0028] During use, the material enters the cylinder 1 from the feed end, and then is thoroughly mixed by passing through the baffle cone 22 and the feed cone 23 along with the stirring blades 21. The baffle cone 22 guides the flow of the material, helping to reduce disordered movement of the material. In addition, the rotation direction of the baffle cone 22 and the stirring blades 21 are matched to form a specific material flow pattern, further improving the mixing effect. The feed cone 23 helps the material to contact the stirring blades 21 more effectively, improving the uniformity of material mixing, making the stones more evenly mixed with other materials, and reducing the situation of too many stones falling off during discharge and too many stones appearing.

[0029] Example 2 Reference Figure 1 This embodiment provides a mixer truck, which includes a vehicle body 3, a mixer drum provided in embodiment 1, and a reducer (not shown in the figure). The mixer drum is rotatably connected to the vehicle body 3, and the reducer is fixed to the vehicle body 3 and drives the mixer drum to rotate.

[0030] The working principle of this utility model is as follows: When in use, the material is loaded into the mixing drum, the reducer is started, and the motor can drive the mixing drum to rotate, so that the mixing mechanism 2 in the drum 1 can fully mix the material, making the material mix more even and reducing the occurrence of too many stones when discharging the material.

[0031] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
