Description

Technical Field

[0001] This invention belongs to the field of filling and feeding technology, specifically a rapid filling and feeding device for the production of tunnel fast excavation support spray coating. Background Technology

[0002] A rapid filling and feeding device for the production of spray coatings for tunnel excavation support is often referred to as an "automatic feeding system" or "rapid filling system." Its design aims to improve production efficiency, reduce manual intervention, and ensure rapid, stable, and efficient material transport. Such equipment typically includes the following core components: an automatic batching system, a screw conveyor, a pneumatic lifting device, etc.

[0003] In existing technologies, when slurry is transported to filling equipment via a screw conveyor, a screw rod is typically used to transport the slurry. Due to the poor fluidity of the slurry or the uneven distribution of material particles, uneven conveying may occur during the screw conveying process, causing fluctuations in material flow and affecting filling accuracy. Summary of the Invention

[0004] To address the issue of poor slurry flowability mentioned in the background art, in some cases, some incompletely moved slurry or other substances may accumulate inside the auger, causing blockage. This affects the continued flow of the slurry, leading to slurry accumulation in that area and increasing flow resistance. Material accumulation may be caused by excessive slurry, excessively high viscosity, or incomplete equipment cleaning. This invention provides a rapid filling and feeding device for the production of roadway rapid excavation support spray coating.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid filling and feeding device for producing roadway rapid excavation support spray coating, comprising a support platform, three support plates fixedly connected to the top of the support platform, a top plate fixedly connected to the top of the support plates, a mixing shell fixedly connected to the bottom of the top plate, a conveying pipe connected to the top of the mixing shell, and a filling and feeding mechanism, comprising a cylinder fixedly connected to the bottom of the mixing shell, a discharge component fixedly connected to the bottom of the cylinder, an electric discharge valve connected to the outer wall of the discharge component, and a filling assembly provided on the top of the top plate for filling the slurry.

[0006] Preferably, the filling assembly includes a motor fixedly connected to the top of the top plate, and a rotating shaft fixedly connected to the output end of the motor. One end of the rotating shaft passes through the mixing shell and extends into the interior of the mixing shell.

[0007] Preferably, a cross-shaped sleeve rod is fixedly connected to the bottom outer wall of the rotating shaft, a spiral rod is sleeved and slidably connected to the outer wall of the cross-shaped sleeve rod, a clamping plate is fixedly connected to the bottom of the cross-shaped sleeve rod, and multiple iron balls are provided at the bottom of the inner wall of the spiral rod.

[0008] Preferably, a cleaning assembly is provided at the top end of the rotating shaft. The cleaning assembly includes a fixed shell fixedly connected to the outer wall of the top end of the rotating shaft, and crossbars are fixedly connected to both sides of the outer wall of the fixed shell.

[0009] Preferably, a curved plate is fixedly connected to the end of the crossbar away from the fixed shell, a sliding rod is slidably connected through the top sidewall of the curved plate, and a cleaning plate is fixedly connected to one end of the sliding rod.

[0010] Preferably, the outer wall of the cleaning plate is disposed in contact with the inner wall of the stirring shell, and a semi-circular curved shell is fixedly connected to both sides of the inner wall of the stirring shell, and a heating tube is fixedly connected to the top of the inner wall of the semi-circular curved shell.

[0011] Preferably, the end of the sliding rod is provided with an auxiliary component, the auxiliary component including a rotating plate hinged to the end of the sliding rod away from the cleaning plate, and a sliding sleeve hinged to the end of the rotating plate away from the sliding rod.

[0012] Preferably, the sliding sleeve is provided as a single unit, with its inner wall slidably connected to the outer wall of the rotating shaft, and multiple vertical rods fixedly connected to the bottom of the sliding sleeve, the bottom of each vertical rod being fixedly connected to the top of the spiral rod.

[0013] Preferably, a round rod is fixedly connected to both sides of the top of the sliding sleeve, the top end of the round rod penetrates the fixed shell and extends into the inner cavity of the fixed shell, and a piston plate is fixedly connected to the top of the round rod.

[0014] Preferably, the outer wall of the piston plate is slidably connected to the top of the inner cavity of the fixed shell, and a plurality of conical springs are fixedly connected to the bottom of the piston plate. The bottom of the conical springs is fixedly connected to the bottom of the inner cavity of the fixed shell, and the conical springs are arranged in eight sections.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of a filling component and a cleaning component, places the storage tank on top of a support platform. Simultaneously, the processed slurry is fed into the mixing shell via a conveying pipe. The motor is started, driving the rotating shaft and cross sleeve to rotate. The cross sleeve then drives the auger to rotate, causing the slurry inside the mixing shell to move into the cylinder. The slurry then enters the discharge component through the cylinder and is subsequently poured into the storage tank, thus enabling rapid filling and feeding. When the rotating shaft rotates, it drives the fixed shell to rotate, which in turn drives the crossbar and curved plate to rotate. The curved plate then drives the sliding rod and cleaning plate to rotate. During rotation, the cleaning plate scrapes the inner wall of the mixing shell, preventing slurry from adhering to the inner wall after prolonged operation and avoiding slurry residue. This effectively prevents material accumulation during mixing, reduces cleaning workload, and ensures the equipment is clean and residue-free after each operation.

[0016] This invention, through the coordinated arrangement of a filling component, a cleaning component, and an auxiliary component, utilizes the heating element inside the semi-circular curved shell to raise the temperature of the slurry inside the mixing shell. This prevents the slurry from cooling down rapidly inside the mixing shell, reduces its viscosity, and improves its fluidity. As the cleaning plate rotates, it contacts the outer wall of the semi-circular curved shell, scraping and cleaning it. This prevents the slurry from overheating and adhering to the outer wall of the shell when the heating element heats the mixing chamber, thus affecting the heating effect of the heating element. The cleaning plate also experiences a reaction force from the curved shell, causing the sliding rod to slide towards the curved plate. The sliding rod then moves the rotating plate, which in turn moves the sliding sleeve vertically down the outer wall of the rotating shaft. The sliding sleeve moves the vertical rod down, which in turn moves the auger vertically down the outer wall of the cross-shaped sleeve. This allows the slurry conveyed by the auger to oscillate between the auger blades, improving its fluidity and preventing poor flow due to excessive viscosity during mixing. This method ensures smooth slurry flow within the cylinder and avoids blockages.

[0017] This invention, through the coordinated arrangement of a filling component, a cleaning component, and an auxiliary component, allows the sliding sleeve to descend, driving the round rod and piston plate to descend within the inner cavity of the fixed shell. When the cleaning plate is no longer in contact with the semi-circular curved shell, the elastic deformation of multiple conical springs and the airtightness of the fixed shell cause the piston plate to return to its original position and rise within the inner cavity of the fixed shell. During the piston plate's ascent, it drives the vertical rod in the auxiliary component to rise, which in turn drives the spiral rod to rise vertically along the outer wall of the cross sleeve. During the spiral rod's ascent, it pushes away any slurry accumulated at the connection between the mixing shell and the cylinder, preventing slurry from accumulating and getting stuck between them. Furthermore, the multiple iron balls inside the spiral rod impact each other during the ascent and descent, further optimizing the slurry's flowability on the outer wall of the spiral rod. This impact slightly improves the slurry's flowability, reduces viscosity, and ensures smooth slurry transport within the cylinder. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0021] like Figures 1 to 8 As shown, the present invention provides a rapid filling and feeding device for the production of roadway rapid excavation support spray coating, including a support platform 1, three support plates 2 are fixedly connected to the top of the support platform 1, a top plate 3 is fixedly connected to the top of the support plate 2, a mixing shell 4 is fixedly connected to the bottom of the top plate 3, and a conveying pipe 5 is connected to the top of the mixing shell 4. The filling and feeding mechanism 6 includes a cylinder 61 fixedly connected to the bottom of the mixing shell 4. A discharge component 62 is fixedly connected to the bottom of the cylinder 61. An electric discharge valve 63 is connected to the outer wall of the discharge component 62. The electric discharge valve 63 can use a pneumatic or electric actuator to control the discharge of slurry and accurately control the discharge amount. It is suitable for industrial applications that require high efficiency and precise control. A filling assembly 64 is provided on the top of the top plate 3 for filling slurry.

[0022] The filling assembly 64 includes a motor 641 fixedly connected to the top of the top plate 3. The motor 641 is a Y132M-4 model with a power range of 2.2kW to 15kW. The motor 641 is suitable for stirring ordinary medium and high viscosity slurries and can provide greater power and lower speed. The output end of the motor 641 is fixedly connected to a rotating shaft 642. One end of the rotating shaft 642 passes through the stirring shell 4 and extends into the interior of the stirring shell 4.

[0023] A cross-shaped sleeve rod 643 is fixedly connected to the outer wall of the bottom end of the rotating shaft 642. A spiral rod 645 is sleeved and slidably connected to the outer wall of the cross-shaped sleeve rod 643. A clamping plate 644 is fixedly connected to the bottom of the cross-shaped sleeve rod 643. Multiple iron balls 646 are provided at the bottom of the inner wall of the spiral rod 645.

[0024] The above-mentioned method involves: placing the storage tank securely on top of the support platform 1, and conveying the processed slurry into the mixing shell 4 via the conveying pipe 5. The motor 641 is then started, driving the rotating shaft 642, which in turn rotates the cross sleeve 643, thereby rotating the screw rod 645. During rotation, the screw rod 645 pushes the slurry within the mixing shell 4 towards the cylinder 61, from where it flows into the discharge component 62. Finally, the slurry is poured from the discharge component 62 into the storage tank, achieving a rapid and efficient filling and feeding process.

[0025] like Figures 1 to 8As shown, a cleaning assembly 65 is provided at the top of the rotating shaft 642. The cleaning assembly 65 includes a fixed shell 651 fixedly connected to the outer wall of the top of the rotating shaft 642. A crossbar 652 is fixedly connected to both sides of the outer wall of the fixed shell 651.

[0026] A curved plate 653 is fixedly connected to the end of the crossbar 652 away from the fixed shell 651. A sliding rod 654 is slidably connected through the top side wall of the curved plate 653. A cleaning plate 655 is fixedly connected to one end of the sliding rod 654.

[0027] The above solution works as follows: When the rotating shaft 642 starts to rotate, it drives the fixed housing 651 to rotate, which in turn drives the crossbar 652 and the bending plate 653 to rotate together. The rotation of the bending plate 653 causes the sliding rod 654 and the cleaning plate 655 to rotate accordingly. During the rotation of the cleaning plate 655, it can effectively scrape off the slurry adhering to the inner wall of the mixing shell 4. In this way, after the equipment has been running for a long time, slurry can be prevented from adhering to the inner wall of the mixing shell 4, ensuring the normal operation and cleanliness of the equipment.

[0028] The outer wall of the cleaning plate 655 is in contact with the inner wall of the stirring shell 4. Both sides of the inner wall of the stirring shell 4 are fixedly connected to a semi-circular curved shell 656, and a heating tube 657 is fixedly connected to the top of the inner wall of the semi-circular curved shell 656.

[0029] The above solution utilizes the heating element 657 inside the semi-circular curved shell 656 to effectively raise the temperature of the slurry inside the mixing shell 4, preventing rapid cooling and viscosity reduction during mixing, thereby improving the slurry's fluidity. Simultaneously, as the cleaning plate 655 rotates, it contacts the outer wall of the semi-circular curved shell 656, effectively scraping and cleaning it. This prevents slurry from adhering to the outer wall of the semi-circular curved shell 656 due to overheating of the heating element 657 during heating, which could affect the heating effect and potentially cause equipment malfunction.

[0030] An auxiliary component 66 is provided at the end of the sliding rod 654. The auxiliary component 66 includes a rotating plate 661 hinged to the end of the sliding rod 654 away from the cleaning plate 655. A sliding sleeve 662 is hinged to the end of the rotating plate 661 away from the sliding rod 654.

[0031] The sliding sleeve 662 is arranged in a single configuration. The inner wall of the sliding sleeve 662 is slidably connected to the outer wall of the rotating shaft 642. Multiple vertical rods 663 are fixedly connected to the bottom of the sliding sleeve 662, and the bottom of the vertical rods 663 is fixedly connected to the top of the spiral rod 645.

[0032] Using the above scheme: Under the reaction force of the semi-circular curved shell 656, the cleaning plate 655 pushes the sliding rod 654 to slide towards the curved plate 653. The sliding rod 654 drives the rotating plate 661 to move, which in turn drives the sliding sleeve 662 to descend vertically along the outer wall of the rotating shaft 642. The descent of the sliding sleeve 662 causes the vertical rod 663 to descend accordingly, and the vertical rod 663 then pushes the spiral rod 645 to descend vertically along the outer wall of the cross sleeve rod 643. Through this series of movements, the spiral rod 645 can fully shake and agitate the slurry between the spiral blades, effectively promoting the fluidity of the slurry and ensuring its smooth delivery.

[0033] Both sides of the top of the sliding sleeve 662 are fixedly connected with round rods 664. The top of the round rods 664 penetrates the fixed shell 651 and extends into the inner cavity of the fixed shell 651. The top of the round rods 664 is fixedly connected with piston plates 665.

[0034] The outer wall of the piston plate 665 is slidably connected to the top of the inner cavity of the fixed shell 651. A plurality of conical springs 666 are fixedly connected to the bottom of the piston plate 665. The bottom of the conical springs 666 is fixedly connected to the bottom of the inner cavity of the fixed shell 651. There are eight conical springs 666.

[0035] The above-mentioned scheme works as follows: During the ascent of the piston plate 665, it drives the vertical rod 663 in the auxiliary assembly 66 to rise together. The vertical rod 663 pushes the spiral rod 645 to rise vertically along the outer wall of the cross sleeve rod 643. When the spiral rod 645 rises, it can effectively push the slurry accumulated at the connection between the mixing shell 4 and the cylinder 61, preventing the slurry from accumulating or getting stuck at this position, ensuring that the channel between the mixing shell 4 and the cylinder 61 is unobstructed, and further improving the working efficiency of the equipment.

[0036] Working principle and usage process of this invention: The storage tank is placed on top of the support platform 1, and the processed slurry is simultaneously fed into the mixing shell 4 through the conveying pipe 5. The motor 641 is started, and the motor 641 drives the rotating shaft 642 and the cross sleeve rod 643 to rotate. The cross sleeve rod 643 drives the screw rod 645 to rotate. During the rotation of the screw rod 645, the slurry inside the mixing shell 4 moves into the cylinder 61. The slurry enters the discharge part 62 through the cylinder 61 and is then poured into the storage tank, thus performing a rapid filling and feeding operation. When the rotating shaft 642... When the shaft 642 rotates, the rotating shaft 642 drives the fixed shell 651 to rotate. The fixed shell 651 drives the crossbar 652 and the bending plate 653 to rotate. The bending plate 653 drives the sliding rod 654 and the cleaning plate 655 to rotate. During the rotation of the cleaning plate 655, the inner wall of the mixing shell 4 can be scraped to prevent the slurry from adhering to the inner wall of the mixing shell 4 after long-term operation. This avoids the accumulation of slurry during the mixing process, reduces the amount of cleaning work, and ensures that the equipment is clean and free of residue after each operation.

[0037] Heating by the heating element 657 inside the semi-circular curved shell 656 raises the temperature of the slurry inside the mixing shell 4, preventing rapid cooling and reducing viscosity while improving fluidity. As the cleaning plate 655 rotates, its curved sidewalls contact the arc-shaped outer wall of the semi-circular curved shell 656, causing it to slide along the arc surface and scrape clean the outer wall. This prevents overheating of the slurry when the heating element 657 heats the mixing shell 4, which would otherwise affect the heating effect of the heating element 657. Furthermore, the cleaning plate 655 gradually moves away from the arc surface of the semi-circular curved shell 656 due to the reaction force of the shell. At the outer wall of the mixing shell 4, the semi-circular curved shell 656 exerts pressure, causing the cleaning plate 655 to slide along the sliding rod 654 towards the curved plate 653. The sliding rod 654 then moves the rotating plate 661, which in turn moves the sliding sleeve 662 vertically down the outer wall of the rotating shaft 642. The sliding sleeve 662 then moves the vertical rod 663 down, which in turn moves the auger 645 vertically down the outer wall of the cross sleeve rod 643. This allows the slurry conveyed by the auger 645 to oscillate between the spiral blades of the auger 645, improving the slurry's fluidity and preventing it from becoming sluggish due to excessive viscosity during mixing. This method ensures smooth flow of the slurry within the cylinder 61, preventing blockages.

[0038] When the sliding sleeve 662 descends, it drives the round rod 664 and the piston plate 665 to descend within the cavity of the fixed shell 651. When the cleaning plate 655 is no longer in contact with the semi-circular curved shell 656, the piston plate 665 is reset and rises within the cavity of the fixed shell 651 due to the elastic deformation of multiple conical springs 666 and the airtightness of the fixed shell 651. During the rise of the piston plate 665, it drives the vertical rod 663 in the auxiliary component 66 to rise. The vertical rod 663 drives the spiral rod 645 to rise vertically along the outer wall of the cross sleeve rod 643. During the rise of the spiral rod 645, it can push the slurry accumulated at the connection between the mixing shell 4 and the cylinder 61, preventing the slurry from accumulating and getting stuck between the mixing shell 4 and the cylinder 61. In addition, the multiple iron balls 646 inside the spiral rod 645 collide during the rise and fall, further optimizing the fluidity of the slurry on the outer wall of the spiral rod 645. This impact can slightly improve the flow of the slurry, reduce viscosity, and ensure smooth transport of the slurry inside the cylinder 61.
