Description

Technical Field

[0001] This utility model relates to the field of fluidized solidified soil processing, and more specifically, to a grinding head with a bulk material structure. Background Technology

[0002] Construction waste disposal remains a persistent challenge. Due to the large proportion of construction waste, traditional landfill methods are not environmentally friendly and can lead to ground subsidence. Furthermore, traditional backfilling methods require layered compaction with high density requirements, which is difficult to achieve in confined spaces, resulting in extended construction periods and increased labor costs. Moreover, traditional materials such as sand, gravel, and earthwork have discrete cavities, and insufficient compaction can easily lead to settlement and ground subsidence. Therefore, fluidized bed solidification has become the main method for handling construction waste in the current construction industry. Fluidized bed solidification uses waste soil and slurry as raw materials to achieve internal recycling within the project, reducing sand and gravel mining and cement usage to meet the requirements of low-carbon economy.

[0003] Currently, in the processing of fluidized solidified soil, excavators are typically used to dig up construction waste, which is then crushed. The crushed material is then placed in a mixer and mixed with water, additives, etc., to form fluidized solidified soil for backfilling.

[0004] The above method has the following drawbacks: due to the wide variety of construction waste and the significant differences in soil quality in different regions, such as sand, clay, and even steel bars from the construction site, the current method relies solely on crushing and mixing. Since the crushed waste is still in a gravel state, the resulting fluidized solidified soil is prone to segregation, bleeding, and stratification, meaning that it cannot achieve a fully mixed and uniform state of mud and water. As a result, the soil structure is poor when backfilling. In addition, the hard fragments such as steel bars contained in the construction waste can easily damage the equipment.

[0005] In order to process construction waste into smaller particles for fluidized solidification, the applicant proposed to use grinding instead of crushing. During grinding, the pre-crushed construction waste particles need to be placed into the grinding roller groove for grinding. However, the current grinding head does not have a structure to disperse the material evenly, resulting in poor and uneven grinding effect.

[0006] Therefore, improvements were made to the grinding head connector to ensure uniformity. Utility Model Content

[0007] The main objective of this application is to provide a grinding head with a material distribution structure, in which pre-crushed construction waste particles are evenly dispersed into the grinding head for grinding through a material distribution disc assembly, resulting in good uniformity.

[0008] To achieve the above objectives, in a first aspect, this application provides a grinding head with a material distribution structure, including a central shaft assembly, at least two grinding rollers fixedly disposed relative to the central shaft assembly, and a material distribution plate assembly fixedly disposed on the top of the central shaft assembly; the material distribution plate assembly includes a conical material distribution plate body, and the edge of the material distribution plate body is provided with a plurality of material discharge ports.

[0009] Optionally, the edge of the fabric tray body is fixedly provided with several baffles by fasteners, and the material discharge port is opened on the baffles.

[0010] Optionally, the baffle is detachably connected to the fabric tray body.

[0011] Optionally, the central shaft assembly includes a central shaft body, a plurality of mounting fins uniformly fixed on the upper outer periphery of the central shaft body, the grinding roller being fixedly mounted on the corresponding mounting fins, and a power assembly being connected to the bottom of the central shaft body.

[0012] Optionally, the power assembly includes a speed reducer and a drive motor, the drive motor being connected to the speed reducer, and the speed reducer being connected to the central shaft body via a coupling.

[0013] Optionally, the fabric tray body has at least a plurality of first mounting holes and second mounting holes along its radial direction, and the baffle is fixedly mounted on the fabric tray body through the first mounting holes or the second mounting holes.

[0014] The present invention provides a grinding head with a material dispersing structure. Compared with the prior art, its advantages are as follows: after the construction waste is crushed by the crusher, it falls onto the material distribution disc body under its own weight. During operation, the material distribution disc body rotates together with the central shaft assembly, thereby dispersing in all directions under the action of centrifugal force. The edge of the disc has a material discharge port, so the construction waste particles fall into the grinding groove from the material discharge port, realizing uniform material dispersion and improving grinding uniformity.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0022] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0023] In addition, the term "multiple" should mean two or more.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-2As shown, a grinding head with a material distribution structure includes a central shaft assembly, at least two grinding rollers 2 fixedly disposed relative to the central shaft assembly, and a material distribution plate assembly fixedly disposed on the top of the central shaft assembly; the material distribution plate assembly includes a conical material distribution plate body 4, and the edge of the material distribution plate body 4 is provided with a plurality of material drop ports 6.

[0026] The cone-shaped feeding disc body 4 is used. When the crushed particles fall, they can be dispersed in all directions due to the cone shape. Moreover, as the feeding disc body 4 rotates with the central axis, the centrifugal force generated also disperses the particles in all directions, and finally they fall from the discharge port 6, thus achieving uniform feeding.

[0027] Specifically, considering cost, efficiency, and stability, the preferred number of grinding rollers 2 is three. This ensures that the three grinding rollers 2 are evenly distributed within the circular grinding groove, resulting in good stability. Furthermore, the simultaneous grinding by the three grinding rollers 2 improves efficiency.

[0028] To allow for adjustment based on the size of different pulverized particles to meet various application scenarios, several baffles 5 are fixedly installed on the edge of the feeding disc body 4 using fasteners. The material discharge port 6 is opened on the baffles 5. The baffles 5 are detachably connected to the feeding disc body 4. The feeding disc body 4 has at least several first mounting holes and second mounting holes along its radial direction. The baffles 5 are fixedly installed on the feeding disc body 4 through the first mounting holes or the second mounting holes. By installing the baffles 5 in different positions, the gap between the baffles 5 and the inner wall of the shell can be adjusted to suit different pulverized particles, thereby achieving controllable material size and allowing for the filtering of hard particles according to actual conditions.

[0029] The central shaft assembly includes a central shaft body 1 and several mounting fins 3 uniformly fixed on the upper outer periphery of the central shaft body 1. The grinding roller 2 is fixedly mounted on the corresponding mounting fins 3. A power assembly is connected to the bottom of the central shaft body 1. The power assembly includes a reducer and a drive motor. The drive motor is connected to the reducer. The reducer is connected to the central shaft body 1 through a coupling.

[0030] The central shaft body 1 is driven to rotate by the drive motor, which in turn drives the grinding roller 2 to rotate, thereby grinding the crushed particles that fall into the grinding trough. In actual application, the crushed particles and water fall into the grinding trough together, so that not only are the crushed particles ground, but they can also be mixed with water, so there is no need for subsequent stirring. In addition, the grinding speed can be controlled by setting a speed reducer.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
