Description

Technical Field

[0001] The utility model relates to the technical field of crushing and grinding rotors, and in particular to a cutter disc rotor structure. Background Art

[0002] With the development of society and the improvement of industrialization level, equipment with crushing and grinding functions plays a huge role in food, chemical, pharmaceutical and other industries. The key component of such equipment - rotor assembly is particularly important. A good rotor assembly runs smoothly, has low vibration, long life and high work efficiency.

[0003] Currently, the rotor assemblies available on the market come in a variety of shapes, and most of them are constructed using a rotary tool holder with attached cutting tools. The cutting tools are bolted to the disc-shaped tool holder and are evenly distributed around its periphery, parallel to the axis of rotation. The high-speed rotation of the cutting tools impacts and shears the material, pulverizing it. However, in such rotor assemblies, the cutting tools are often very long, with one cutting tool occupying the entire working area. During rotary grinding, the material is not evenly spread, but rather, due to the combined effects of impact, inertia, and centrifugal forces, tends to skew to one side, or to a greater extent, to one side. This not only reduces tool utilization, but also makes the side with the heaviest load more susceptible to chipping and damage. Once damaged, the entire blade must be replaced. However, due to its length, less than half of the blade is damaged, leaving the remaining blade wasted and costly to replace.

[0004] Therefore, how to provide a cutter rotor structure that can crush and grind materials relatively evenly, improve the utilization rate of the cutter, enable the cutter to be replaced quickly and conveniently, and improve the grinding efficiency while reducing the cost of tool maintenance has become a technical problem that needs to be urgently solved by technical personnel in this field.

In the cutter disc rotor structure, multiple pieces of the stepped flanges are installed on the side wall of the tool holder base in the vertical direction, and each piece of the stepped flange is detachably connected to a group of the cutter disc assemblies, so that the cutter disc assembly is divided into multiple layers, which is convenient for the quick installation and replacement of the cutter disc assembly, and when the blade is slightly damaged, there is no need to replace the entire assembly, which greatly reduces the maintenance cost; secondly, for the same reason, it is also affected by gravity.

When the material falls under the influence of gravity, it is received by the small grids formed by the cutter assembly below. The overlapping effect realizes the uniform spreading of the material, which can make all the small grids evenly participate in the crushing and grinding work. The space utilization rate of the rotor and the utilization rate of the cutter are extremely high, achieving uniform grinding of the material, high working efficiency of the whole machine, and achieving the purpose of reducing power consumption. It can be seen that the technical solution provided by the utility model is more uniform than that of the prior art, which can crush and grind the material relatively evenly, improve the utilization rate of the cutter, and make the cutter quick and convenient to replace. While reducing the maintenance cost of the cutter, it also improves the working efficiency of the grinding. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] As described above, the cutterhead rotor structure provided by the embodiment of the utility model is mainly used for filling the gap between the excavation diameter of the shield machine and the outer diameter of the pipe segment, so as to solve the problem that the solidification time of the single-liquid cement mortar is long, and the single-liquid cement mortar stays in the tail shield channel for a long time after grouting, which will cause solidification and blockage of the pipeline. The use of double-liquid grouting will aggravate the blockage of the pipeline, making the pipeline difficult to clean and maintain. In the cutter disc rotor structure described in the present invention, its main structure consists of the tool holder base 1, cover plate 2, locking washer 3, stepped flange 4, cutter disc assembly 5, partition flange 6 and the partition assembly 7; the cutter disc rotor structure adopts a vertical structure. Compared with the horizontal structure, the material will be affected by gravity and mainly concentrated at the bottom, while in the vertical structure, the material is evenly distributed around, and the knives 10 in each group of the cutter disc assembly 5 can contact the material. In the cutter disc rotor structure, multiple pieces of the stepped flange 4 are installed on the side wall of the tool holder base 1 in the vertical direction, and each piece of the stepped flange 4 can be detachably connected to a group of the cutter disc assembly 5, so that the cutter disc assembly 5 is divided into multiple layers, which is convenient for the cutter disc assembly 5 to be quickly installed and replaced, and when the blade is slightly damaged, there is no need to replace the entire assembly, which greatly reduces the maintenance cost; secondly, for the same reason, it is also affected by gravity. The traditional cutter disc When the rotor is working, most of the material is in contact with the bottom of the tool. On this basis, the cutter disc rotor structure adopts a vertical cone structure. From top to bottom, the diameter of each layer of the cutter disc assembly 5 is larger than that of the previous layer, and the partition flange 6 is installed between the cutter disc assemblies 5. The partition assembly 7 is arranged on the partition flange 6. Each layer of the cutter disc assembly 5 is separated by the partition assembly 7. The upper and lower partition assemblies 7 and the tool 10 can be enclosed into a grid shape. When the material falls, it will be evenly divided into all the small grids of a layer in the horizontal direction. When the material falls under the influence of gravity, it is received by the small grids enclosed by the cutter disc assembly 5 below. The overlapping effect realizes the uniform spreading of the material, and enables all the small grids to evenly participate in the crushing and grinding work. The space utilization rate of the rotor and the utilization rate of the tool are extremely high, which realizes the uniform grinding of the material. The working efficiency of the whole machine is high, and the purpose of reducing power consumption can be achieved. It can be seen that the technical solution provided by the present invention, compared with the existing technology, can crush and grind materials relatively evenly, improve the utilization rate of the tool, enable the tool to be replaced quickly and conveniently, and improve the grinding work efficiency while reducing the tool maintenance cost.
