The reason for this stratification is the extreme difference in the physical properties of the two materials. Under the mechanical action of gravity, inertia, airflow, etc., the particle movement trajectory and speed are different, which eventually leads to the separation of "light and heavy materials", thus requiring further intervention during the filling process. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In current filling processes, EPS particles and waste-based materials are prone to stratification during flow. This stratification is essentially due to the extreme differences in the physical properties of the two materials. Under the influence of gravity, inertia, and airflow, the particles move at different trajectories and speeds, ultimately leading to the separation of the "light and heavy materials." This necessitates further intervention during the filling process. Therefore, to address these issues, this paper proposes the following technical solution:

[0035] Please see Figures 1 to 7 This invention provides a technical solution for a filling equipment for mixing EPS particles and waste residue-based materials: its structure includes: a filling gun 1, the filling gun 1 is connected to a pump head 4 through a pipe, one end of the pump head 4 is connected to the filling gun 1, and the other end is connected to a machine body 5, the top of the machine body 5 is provided with a feeding hopper 3, the feeding hopper 3 is controlled by a control box 2 installed on the top of the machine body 5, the filling gun 1 includes a connector 11, the connector 11 is connected to the pump head 4 through a conduit, the connector 11 is connected to a base 12, a first handle 13 and a second handle 14 are respectively provided on the surface of the base 12, one end of the base 12 is connected to the connector 11, and the other end is connected to an adjusting base 15, a pipe head 16 is nested inside the adjusting base 15, the pipe head 16 is movably connected to the adjusting base 15, and a protective cover 17 is provided at the connection between the adjusting base 15 and the pipe head 16 for sealing, one side of the adjusting pipe 163 of the pipe head 16 is provided with a spherical protrusion, which is nested and cooperates with the adjusting base 15.

[0036] The main structure of this device includes a body 5, inside which is a drive motor that drives the screw inside the pump head 4 to rotate. A feed hopper 3 is provided on the top of the pump head 4. The feed hopper 3 is used to connect to the mixing and conveying pipe to further mix and homogenize the EPS particles and waste residue base mixture after mixing. After being sent out by the pump head 4, the filling operation is completed by the filling gun 1.

[0037] The base 12 of the filling gun 1 is provided with a connector 11 at one end, which is connected to the pump head 4 through a pipe. The base 12 is equipped with a first handle 13 and a second handle 14 for easy hand operation; an adjusting base 15 is provided on one side of the base 12, which is used to fix the pipe head of the adjusting pipe 163. A protective cover 17 is provided between the adjusting base 15 and the adjusting pipe 163 for joint protection.

[0038] During the filling process, due to the large mass of the waste residue and the light weight of the EPS particles, stratification is likely to occur during transportation. To address this, the device has been specifically optimized: a baffle 167 is installed inside the regulating pipe 163. During transportation, the EPS particles will converge towards the center under the resistance of the baffle 167, thereby achieving further mixing.

[0039] To make the mixing more dynamic, the regulating pipe 163 is designed to vibrate within a small range under the scouring of the fluid. During concrete pumping, waste residue-based materials tend to concentrate directly below the discharge port due to inertia, leading to local accumulation. However, the oscillation of the pipe opening allows the concrete flow to fall in a dispersed manner, with the waste residue-based materials being evenly distributed in the fill area, fully mixing with the EPS particles. This avoids the problem of waste residue-based materials clumping together or areas lacking EPS particles, ensuring the uniformity of the concrete composition.

[0040] The function is achieved by: a spring plate 164 being provided on the surface of the regulating tube 163, which supports the regulating tube 163 and maintains a reasonable gap between the regulating tube 163 and the outer ring 151. The regulating tube 163 and the outer ring 151 are nested and engaged by a ball joint on the surface of the regulating tube 163 and an inner sliding ring 152 inside the outer ring 151. The elasticity of the spring plate 164 keeps the regulating tube 163 in a centered position. The regulating tube 163 is connected to the first connecting ring 161 through a telescopic tube 162. The thread of the first connecting ring 161 engages with the internal thread of the base 12, and the adjusting base 15 engages with the external thread of the base 12. When the regulating tube 163 swings, the telescopic tube 162 moves synchronously with it and continuously feeds material, reducing leakage at the joint; the outer ring 151 protects the telescopic tube 162, preventing it from being damaged under external force.

[0041] To prevent fatigue damage to the spring 164, a spring 166 is provided between the spring 164 and the adjusting tube 163, and is limited by a protective cover 165 that fastens into the hole of the spring 164. During installation, the protective cover 165 is nested in the movable groove inside the outer ring 151, and the swing amplitude of the adjusting tube 163 is limited by the limiting groove 156 of the positioning inner ring 155.

[0042] Due to the large weight of the fluid, a buffer block 153 is provided inside the outer ring 151 to provide support. The buffer block 153 is a rubber block. Multiple release grooves 154 are formed on the surface of the buffer block 153 to increase its deformation range and at the same time play a shock absorption role, thereby improving the performance.

[0043] To prevent mud and water from affecting the gap between the spring 164 and the adjusting tube 163 and the outer ring 151, thus reducing the flexibility of movement, this device is equipped with a protective cover 17 for transitional protection: the fixing ring 171 is clamped to the outside of the spring 164 through the fixing groove 172, the cover 173 is made of rubber, and the second connecting ring 174 at its end is nested with the outer ring 151, which can play a role in preventing mud and water from entering during the movement of the device.

[0044] How to use this device:

[0045] 1: Connect the filling gun 1 to the pump head 4 via the connector 11 of the base 12 of the filling gun 1 using a pipe; connect the mixing conveying pipe to the feed hopper 3 and ensure that all interfaces are sealed and leak-free.

[0046] 2: Confirm that the protective cover 17 (including the fixing ring 171 and the second connecting ring 174) is installed in place and is not loose; check that the fit clearance between the adjusting tube 163 and the outer ring 151 is normal, the spring 164 and the spring 166 are not deformed, and the buffer block 153 is not damaged.

[0047] 3: The operator holds the first handle 13 and the second handle 14 of the base 12, aligns the adjusting tube 163 of the filling gun 1 with the filling operation area, and then turns on the drive motor inside the machine body 5. The motor drives the screw inside the pump head 4 to rotate, starting the feeding power.

[0048] The mixed EPS particles and waste residue base mixture are poured into the feed hopper 3. After further mixing and homogenization in the feed hopper 3, the mixture enters the pump head 4. Under the push of the screw, the mixture is transported through the pipeline to the regulating pipe 163 of the filling gun 1. Guided by the turbulence strip 167 inside the regulating pipe 163, the EPS particles converge towards the center. At the same time, the mixture washes over the regulating pipe 163, causing it to vibrate in a small range under the support of the spring 164 and the spring 166, so as to achieve dynamic and uniform mixing of materials.

[0049] By holding the first handle 13 and the second handle 14, the angle and position of the filling gun 1 can be flexibly adjusted to ensure that the mixture is evenly spread in the working area; if the height of the nozzle needs to be finely adjusted, it can be adapted by adjusting the external thread fit between the base 15 and the base 12.

[0050] After the filling operation is completed, stop feeding material into the feed hopper 3. After the remaining material in the pump head 4 and regulating pipe 163 is emptied, turn off the drive motor of the machine body 5, disassemble the connecting pipes, and clean the residual material inside the feed hopper 3, pump head 4, regulating pipe 163 and protective cover 17. Check the wear of the spring 164, spring 166 and buffer block 153, and replace the damaged parts in time to ensure the reliability of the next use.

[0051] The improved device guides EPS particles to converge towards the center through the turbulence strip 167 inside the regulating pipe 163, effectively alleviating the stratification of light and heavy materials. Combined with the small-range automatic vibration design of the regulating pipe 163 under fluid scouring, it avoids the waste residue base material from accumulating due to inertia, realizing dynamic and uniform mixing of waste residue base and EPS particles, solving the problems of material clumping and local lack of EPS particles, ensuring the consistency of concrete composition, and improving the quality of backfill construction.

[0052] The combined structure of the spring 164 and the spring 166 effectively disperses stress, prevents fatigue damage to the spring 164, and extends the service life of the component. The buffer block 153 inside the outer ring 151 provides stable support and increases the deformation range and enhances the shock absorption effect through the release groove 154, thereby improving the overall structural stability.

[0053] The outer ring 151 protects the telescopic tube 162, preventing it from being damaged by external forces. The protective cover 17 can block mud and water from entering, prevent the spring piece 164 and the adjusting tube 163 from getting stuck in the fit between the outer ring 151, ensure the flexibility of the device, and reduce the frequency and cost of later maintenance.

[0054] The above description only outlines the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and modifications based on the above description, and these changes and modifications should fall within the protection scope of the present invention.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
