Description

Technical Field

[0001] This invention relates to the fields of coal mining and geotechnical engineering research and technology, and in particular to an intelligent laying system for model test materials with quick-insertion material conveying. Background Technology

[0002] In fields such as underground coal seam mining, the on-site construction environment is complex, the research is difficult, and major accidents are prone to occur, causing unnecessary casualties and economic losses. However, physical simulation tests are often used as a method for studying underground engineering because of their advantages such as repeatability, simple and safe operation, ability to simulate working conditions under various conditions, and ease of control.

[0003] Physical simulation testing is a method that uses a test model to simulate on-site working conditions by converting on-site conditions through a certain similarity ratio. It can reflect the relationship between geological structures and engineering structures, more accurately simulate the construction process and its impacts, and provide more intuitive test results, making it easier to analyze the stress distribution, deformation patterns, and stability characteristics of rock mass engineering. Therefore, configuring suitable geological similarity materials and properly transporting and fabricating the model are necessary conditions for completing similarity simulation tests. Traditional similarity simulation tests rely on manual material preparation, transportation, and placement, resulting in low automation and a relatively complex process.

[0004] The existing methods for batching, conveying, and spreading similar materials mainly include the following:

[0005] Chinese patent ZL201510889401.1 discloses "an automatic material spreading device and its usage method for similar material simulation tests." In this invention, the material outlet of the container begins to discharge material under the up-and-down vibration of a vibrating device. During the discharge process, an operator controls the vibrating device to spread and compact the material using a handheld switch box. However, this device requires manual addition of similar materials to the container, and manual operation of the switch to control the direction and speed of the vibrating device is necessary. Manual replenishment of material is also required during the spreading process, resulting in low efficiency.

[0006] Chinese patent ZL201510475636.6 invented a similarity simulation experimental system and method based on 3D printing rapid prototyping technology. This invention can lay models of complex geological structures such as folds, faults, and collapse columns that cannot be laid using traditional methods. However, this invention has several drawbacks during the material conveying process. The mixing of dry and wet materials can easily cause material blockage in the conveying pipe, affecting the conveying efficiency. Furthermore, the material cannot be fully covered during laying, resulting in uneven laying. The lack of a compaction device also leads to a reduction in material strength.

[0007] Chinese patent ZL 201910378657.4 discloses a feeding mechanism for 3D printing of materials. This mechanism is easy to move and can quantitatively add raw material powder into the printer, enabling non-stop filling and collecting dust scattered during feeding. However, this invention requires the feeding mechanism to move with the printer, making operation complex and lacking automation; furthermore, it can only transport dry powder and cannot transport fluids.

[0008] Existing batching, conveying, and spreading systems each have their own characteristics, but their main limitations are as follows:

[0009] 1) The system is not highly automated and requires a lot of manpower and resources. It cannot automatically fill, weigh, mix, convey, or spread materials.

[0010] 2) Poor sealing during material conveying can easily lead to dust diffusion, which can harm human health; and there is also a risk of dust explosion.

[0011] 3) 3D printing does not have a vibration compaction device, so it is impossible to control the strength and density of the material, which affects the model forming effect and cannot achieve accurate reproduction of complex geology;

[0012] 4) It cannot achieve the separation and conveying of dry and fluid materials. The conveying process of wet materials is prone to clogging of pipelines and low conveying efficiency.

[0013] Developing an intelligent material laying system for model tests with quick-connect feeding, capable of efficiently and conveniently automating the proportioning, mixing, feeding, discharging, and compaction of similar materials, has become a pressing technical problem for those skilled in the art.
