Description

Technical Field

[0001] This application relates to the field of geotechnical engineering, and in particular to a mobile mixing device for fluidized solidified soil. Background Technology

[0002] Fluidized solidified soil is a new type of building material. It makes full use of the soil from excavated trenches, foundation pits, or abandoned foundation soil. After adding a certain proportion of solidifying agent and water, it is thoroughly mixed evenly through a unique process and special machinery to form a pumpable, fluid reinforcement material. It is used for backfilling and pouring of various trenches, foundation pits, and mine pits, and can also be widely used in the reinforcement of roadbeds, building foundations, and other fields.

[0003] Currently, most existing fluidized solidified soils are prepared by mixing with mixing equipment. The mixing equipment mainly includes a batching silo and a mixing drum. When using it, the raw materials such as soil are first added to the batching silo, and the raw materials such as soil are weighed and proportioned using the batching silo. Then, the raw materials are transported to the mixing drum, and solidifying agent and water are added to the mixing drum. Finally, the mixture is mixed in the mixing drum.

[0004] Regarding the aforementioned technologies, the inventors discovered that soil often contains a large number of slag lumps. Soil containing slag lumps is not only less efficient to mix, but if the slag lumps cannot be completely broken up during mixing in the mixing bucket, it will affect the quality of the fluidized solidified soil. Summary of the Invention

[0005] To alleviate the problem that soil slag lumps can easily reduce the mixing efficiency of fluidized solidified soil and affect its quality, this application provides a mobile mixing device for fluidized solidified soil.

[0006] This application provides a mobile mixing device for fluidized solidified soil, which adopts the following technical solution:

[0007] A mobile mixing device for fluidized solidified soil includes a mobile vehicle body, a batching bin, a vibration crushing mechanism, and a mixing mechanism. The batching bin is connected to the mobile vehicle body, and the vibration crushing mechanism is connected to the mobile vehicle body. The vibration crushing mechanism is used to vibrate and stratify the soil and to crush the slag lumps. The mixing mechanism is connected to the mobile vehicle body and is used to mix and prepare the solidified soil raw materials.

[0008] By adopting the above technical solution, a vibration crushing mechanism is installed on the vehicle body. When the solidified soil is mixed and prepared, the soil is first transported to the vibration crushing mechanism, which then vibrates and layers the solidified soil. The resulting slag lumps are then crushed, and the soil is poured into the batching bin. Finally, the mixing mechanism is used to mix the soil. This reduces the possibility of slag lumps in the soil affecting the mixing and forming of the fluidized solidified soil, thereby improving the quality of the fluidized solidified soil.

[0009] Preferably, a support frame is fixedly connected to the mobile vehicle body, the batching bin is fixedly connected to the mobile vehicle body, the vibration crushing mechanism includes a vibrating disc, a vibration component and a crushing component, the vibrating disc is slidably connected to the support frame, the vibration component is connected to the support frame, the vibration component is connected to the vibrating disc to drive the vibrating disc to slide back and forth, the crushing component is connected to the vibrating disc, and the crushing component is used to crush the vibrating and stratified slag blocks.

[0010] By adopting the above technical solution and utilizing the sliding setting of the vibratory plate, before the soil is mixed, the material is first poured into the vibratory plate, and then the vibration component is started. The vibration component drives the vibratory plate to slide and swing back and forth, so that the slag and soil blocks in the vibratory plate float to the upper surface of the soil under the vibration action of the vibratory plate. Then the crushing component is started to crush the slag and soil blocks, and then the soil is poured into the batching bin.

[0011] Preferably, the mixing mechanism includes a mixing tank, a stirring rod, and a rotating assembly. The mixing tank is fixedly connected to the mobile vehicle body. The stirring rod passes through the mixing tank and is rotatably connected to the mixing tank. The rotating assembly is connected to the mixing tank and is connected to the stirring rod to drive the stirring rod to rotate. The vibration assembly includes an eccentric wheel and two fixed plates. The eccentric wheel is rotatably connected to the support frame. The stirring rod is drivenly connected to the eccentric wheel. Both fixed plates are fixedly connected to the vibrating plate and are located on opposite sides of the eccentric wheel. The two fixed plates slide back and forth under the drive of the eccentric wheel.

[0012] By adopting the above technical solution, when the rotating component drives the stirring rod to rotate and mix the solidified soil raw materials in the mixing bucket, the rotating rod can simultaneously drive the eccentric wheel to rotate. The rotation of the eccentric wheel pushes the two fixed plates to move, which in turn drives the vibrating plate to move back and forth, thereby realizing the vibration separation of slag lumps in the soil.

[0013] Preferably, the vibration assembly further includes a second gear and a third gear, the second gear being coaxially and fixedly connected to the stirring rod, the third gear being coaxially and fixedly connected to the eccentric wheel, the second gear and the third gear being meshed, and the diameter of the second gear being larger than the diameter of the third gear.

[0014] By adopting the above technical solution, the diameter of the second gear is larger than that of the third gear. When the stirring rod slowly rotates to mix the soil in the mixing bucket, the transmission ratio between the second and third gears can still ensure the rotation frequency of the eccentric wheel, thereby ensuring the screening effect of the slag lumps.

[0015] Preferably, the crushing assembly includes a second motor, a bidirectional lead screw, and two crushing plates. The second motor is fixedly connected to the vibrating plate, and the bidirectional lead screw is rotatably connected to the vibrating plate. The second motor and the bidirectional lead screw are driven together. The bidirectional lead screw is threadedly connected to two sliders, both of which are slidably connected to the vibrating plate. Each slider is fixedly connected to a crushing plate. The bidirectional lead screw drives the two crushing plates to move in a direction that approaches or moves away from each other.

[0016] By adopting the above technical solution, after the slag blocks are screened out, the second motor is started. The second motor drives the bidirectional lead screw to rotate, which in turn drives the two crushing plates to move in a direction that approaches each other. This allows the two crushing plates to crush the slag blocks that float up in the vibrating plate, thus achieving the treatment of slag blocks in the soil.

[0017] Preferably, a curing agent adding mechanism is installed on the support frame. The curing agent adding mechanism includes a placement box, a pumping component, and a spraying component. The placement box is fixedly connected to the support frame and contains liquid curing agent. The pumping component is connected to the placement box and is used to pump the liquid curing agent into the mixing tank. The spraying component is connected to the placement box and is used to spray the liquid curing agent into the vibratory feeder.

[0018] By adopting the above technical solution, when the vibrating plate moves back and forth to turn and screen the soil, the spraying component simultaneously sprays liquid solidifying agent into the soil in the vibrating plate. Thus, as the soil is turned, the solidifying agent is sprayed into the soil, so that the solidifying agent is added evenly to the soil, thereby improving the uniformity of the solidified soil mixture.

[0019] Preferably, the spraying assembly includes a liquid outlet pipe, a jet nozzle, and a power component. The liquid outlet pipe is fixedly connected to the placement box and extends into the placement box. The jet nozzle is fixedly connected to the support frame and has a retractable corrugated structure. A jet pipe is connected to the side of the jet nozzle near the vibrating plate. The jet nozzle's jet outlet is opposite to the liquid outlet pipe's water outlet. The jet direction of the airflow in the jet pipe is perpendicular to the jet direction of the water flow in the liquid outlet pipe. An air inlet pipe is connected to the jet nozzle, and a first one-way valve is provided on the air inlet pipe. The first one-way valve allows external air to flow only from the outside to the inside of the jet nozzle in one direction. The power component is connected to the vibrating plate and is connected to the jet nozzle to drive the jet nozzle to extend and retract.

[0020] By adopting the above technical solution, during the sieving and stratification of soil, the extension and retraction of the jet cylinder is driven by a power component, allowing external gas to enter the jet cylinder through the air inlet pipe. When the jet cylinder is retracted, the gas inside the jet cylinder is ejected from the jet pipe. Since the jet pipe and the liquid outlet pipe correspond, when the airflow inside the jet cylinder is ejected from the jet pipe, the pressure at the liquid outlet of the liquid outlet pipe will decrease. This causes the liquid solidifying agent in the placement box to be ejected from the liquid outlet pipe under atmospheric pressure, and under the impact of the airflow, it forms a water mist that is sprayed onto the soil in the vibrating plate. During the sieving stage, the solidifying agent sprayed onto the soil is simultaneously turned over, improving the uniformity of solidifying agent addition.

[0021] Preferably, the power component is a power rod, which is fixedly connected to the vibratory feeder and to the end of the jet tube furthest from the vibratory feeder.

[0022] By adopting the above technical solution, and using a power rod, the mixing rod synchronously drives the vibratory plate to swing back and forth to turn the soil. When the vibratory plate moves towards the jet nozzle, the jet nozzle will extend along with the movement of the vibratory plate. At this time, air from the external environment will be drawn into the jet nozzle through the air inlet pipe. Then the vibratory plate moves back, and during the return movement, it drives the jet nozzle to contract. The gas in the jet nozzle will be sprayed out through the jet pipe, so that the curing agent can be sprayed in accordance with the sieving frequency of the soil in the vibratory plate, thereby further improving the uniformity of curing agent addition.

[0023] Preferably, the vibratory feeder is provided with a pushing assembly, which includes an electric pusher cylinder and a pusher plate. The electric pusher cylinder is fixedly connected to the vibratory feeder, and the pusher plate is slidably connected to the vibratory feeder. The piston rod of the electric pusher cylinder is connected to the pusher plate to drive the pusher plate to slide. The pusher plate is used to push the soil out of the vibratory feeder.

[0024] By adopting the above technical solution, after the slag blocks are processed, the electric pusher cylinder can be activated to push the soil off the vibratory plate, thus facilitating the soil to enter the batching bin.

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] 1. By installing a vibration crushing mechanism on the vehicle body, when preparing solidified soil, the soil is first transported to the vibration crushing mechanism, and the solidified soil is vibrated and layered. Then, the slag and soil blocks that appear in the layer are crushed. The soil is then poured into the batching bin, and then the soil is mixed by the mixing mechanism. This reduces the possibility of slag and soil blocks affecting the mixing and forming of fluidized solidified soil and improves the quality of fluidized solidified soil.

[0027] 2. By setting a curing agent addition mechanism on the support frame, when the vibrating plate moves back and forth to turn and screen the soil, the spraying component simultaneously sprays liquid curing agent into the soil in the vibrating plate. Thus, as the soil is turned over, the curing agent is sprayed into the soil at the same time, so that the curing agent is added to the soil evenly, thereby improving the uniformity of the solidified soil mixture.

[0028] 3. By using the material pushing component on the vibratory plate, after the slag blocks have been processed, the electric pusher cylinder can be activated to push the soil off the vibratory plate, thus facilitating the entry of the soil into the batching hopper. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a mobile mixing device for fluidized solidified soil.

[0038] Reference Figure 1 and Figure 2 A mobile mixing device for fluidized solidified soil includes a mobile vehicle body 100, a support frame 110 fixedly connected to the mobile vehicle body 100, and a batching hopper 200 fixedly connected to the support frame 110. A discharge conveyor 210 is fixedly connected to the support frame 110, and the discharge conveyor 210 is located below the discharge port of the batching hopper 200. A mixing mechanism 300 is installed on the mobile vehicle body 100. The discharge conveyor 210 is used to transport soil into the mixing mechanism 300, which is used to mix materials such as soil, solidifying agent, and water. To facilitate soil loading, in other embodiments, a loading conveyor can be installed on the support frame 110 to transport the soil into the batching hopper 200 for batching and weighing.

[0039] Reference Figure 2The mixing mechanism 300 includes a mixing tank 310, which is fixedly connected to the mobile vehicle body 100. The mixing tank 310 is vertically arranged, and a stirring rod 320 is inserted through the mixing tank 310. The stirring rod 320 is rotatably connected to the mixing tank 310, and multiple stirring blades are fixedly connected to the stirring rod 320. A rotating assembly 330 is installed on the mixing tank 310. The rotating assembly 330 includes a first motor 331 fixedly connected to the mixing tank 310. A first gear 332 is coaxially fixedly connected to the main shaft of the first motor 331, and another first gear 332 is coaxially fixedly connected to the stirring rod 320. The two first gears 332 are meshed together. In the preparation of solidified soil, the soil is first transported into the storage silo for weighing. Then, the soil, solidifying agent, and water are added to the mixing tank 310 according to the ratio. Then, the first motor 331 is started, and the stirring rod 320 is driven by the first motor 331 to stir and mix the various raw materials.

[0040] Reference Figure 2 and Figure 3 The raw material soil for fluidized solidified soil is usually various types of engineering waste soil, which inevitably contains a certain amount of waste soil lumps. Directly transporting larger waste soil lumps into the mixing bucket 310 for mixing not only affects the mixing speed of the solidified soil but also its mixing uniformity, thus easily affecting the quality of the solidified soil. To address this, a screening mechanism 400 is installed on the support frame 110. The screening mechanism 400 includes a vibrating plate 410, which is slidably connected to the support frame 110. A vibration component 420 is installed on the support frame 110 to drive the vibrating plate 410 to reciprocate. A crushing component 430 is installed on the vibrating plate 410 to crush the waste soil lumps on the vibrating plate 410.

[0041] Reference Figure 2 and Figure 3 The vibration assembly 420 includes a second gear 421 coaxially fixedly connected to the stirring rod 320, and a third gear 422 rotatably connected to the support frame 110. The diameter of the third gear 422 is smaller than that of the second gear 421. The second gear 421 and the third gear 422 are meshed together. The third gear 422 is coaxially fixedly connected to an eccentric wheel 423. Two fixing plates 424 are fixedly connected to the bottom of the vibrating plate 410. The two fixing plates 424 are located on opposite sides of the eccentric wheel 423. When the first motor 331 drives the stirring rod 320 to stir the solidified soil raw material in the mixing bucket 310, it will simultaneously drive the second gear 421 coaxially fixedly connected to it to rotate. Then, through the cooperation of the second gear 421 and the third gear 422, the eccentric wheel 423 will rotate, which will cause the eccentric wheel 423 to push the vibrating plate 410 to swing left and right, thereby realizing the vibration stratification of the next batch of soil.

[0042] Reference Figure 4 and Figure 5 The crushing assembly 430 includes a second motor 431 fixedly connected to the vibratory feeder 410. The main shaft of the second motor 431 is coaxially fixedly connected to a bidirectional lead screw 432. Two sliders 433 are threadedly connected to the bidirectional lead screw 432. The threads of the two sliders 433 and the bidirectional lead screw 432 are opposite in direction. Each slider 433 is fixedly connected to a crushing plate 434. Both crushing plates 434 are located on the vibratory feeder 410 and are kept at a certain distance from the bottom surface of the vibratory feeder 410. Before the soil is conveyed into the batching silo 200, it is first conveyed into the vibrating plate 410. The soil clumps in the soil will move to the upper surface of the soil under the vibration of the vibrating plate 410. Then, the second motor 431 is started. The second motor 431 drives the bidirectional lead screw 432 to rotate, which drives the two crushing plates 434 to move towards each other. This allows the two crushing plates 434 to crush the soil clumps. Then, the soil is poured into the storage hopper for storage, which reduces the possibility of the presence of soil clumps affecting the quality of the fluidized solidified soil.

[0043] Reference Figure 4 and Figure 5 To facilitate the dumping of soil from the vibratory feeder 410 into the batching hopper 200, a pushing assembly 440 is installed on the vibratory feeder 410. The pushing assembly 440 includes an electric pusher cylinder 441 fixedly connected to the side of the vibratory feeder 410 away from the batching hopper 200. A pusher plate 442 is fixedly connected to the piston rod of the electric pusher cylinder 441 and slidably connected within the vibratory feeder 410. After the soil clumps are removed, activating the electric pusher cylinder 441 pushes the soil off the vibratory feeder 410, facilitating its entry into the batching hopper 200.

[0044] Reference Figure 1 and Figure 3 A curing agent adding mechanism 500 is installed on the support frame 110. The curing agent adding mechanism 500 includes a placement box 510, which is fixedly connected to the support frame 110. The placement box 510 contains liquid curing agent. A pumping assembly 520 is installed on the placement box 510. The pumping assembly 520 is used to pump the liquid curing agent in the placement box 510 into the mixing tank 310. The pumping assembly 520 includes a water pump 521 fixedly connected to the placement box 510. The inlet of the water pump 521 is connected to the inside of the placement box 510 through an inlet pipe. The outlet pipe 522 of the water pump 521 is connected to the inside of the mixing tank 310. A spraying assembly 530 is installed on the placement box 510. The spraying assembly 530 is used to spray the liquid curing agent onto the soil in the vibrating plate 410.

[0045] Reference Figure 4 and Figure 6The spraying assembly 530 includes multiple liquid outlet pipes 531 fixedly connected to the placement box 510, with the multiple liquid outlet pipes 531 spaced apart along the length of the placement box 510. A jet cylinder 532 is fixedly connected to the support frame 110, located on one side of the vibrating plate 410. The jet cylinder 532 is a retractable corrugated structure. Multiple jet pipes 533 are fixedly connected to the side of the jet cylinder 532 closest to the placement box 510. All jet pipes 533 communicate with the interior of the jet cylinder 532. Each jet pipe 533 corresponds one-to-one with a liquid outlet pipe 531, and the airflow direction of each jet pipe 533 is perpendicular to the liquid outlet direction of its corresponding liquid outlet pipe 531. The jet tube 532 has multiple air inlet pipes 534 connected to the side opposite to the multiple jet pipes 533. These air inlet pipes 534 are spaced apart along the length of the jet tube 532. Each air inlet pipe 534 is equipped with a first one-way valve 535, which allows air to flow unidirectionally from the external environment into the jet tube 532. Each jet pipe 533 is equipped with a second one-way valve 536, which allows air to flow unidirectionally from the inside of the jet tube 532 outwards through the jet pipe 533. A power component 537, which is a power rod 538, is mounted on the vibratory feeder 410. The end of the power rod 538 furthest from the vibratory feeder 410 is fixedly connected to the end of the jet tube 532 furthest from the vibratory feeder 410.

[0046] When preparing and mixing the solidified soil, the liquid solidifying agent in the placement box 510 is extracted using a water pump 521 and then pumped into the mixing tank 310. Directly pumping the solidifying liquid requires a longer mixing time and results in poor mixing uniformity. Using the spray assembly 530, when the mixing rod 320 synchronously drives the vibrating plate 410 to reciprocate and turn the soil, as the vibrating plate 410 moves towards the jet nozzle 532, the jet nozzle 532 extends along with the vibrating plate 410. At this time, air from the external environment is drawn into the jet nozzle 532 through the air inlet pipe 534. Then, the vibrating plate 410 moves back... During the transfer process, the jet tube 532 is contracted, and the gas inside the jet tube 532 will be ejected through the jet pipe 533. Since the jet pipe 533 corresponds to the liquid outlet pipe 531, when the airflow in the jet tube 532 is ejected from the jet pipe 533, the pressure at the liquid outlet of the liquid outlet pipe 531 will decrease. This causes the liquid curing agent in the placement box 510 to be ejected from the liquid outlet pipe 531 under atmospheric pressure. Under the impact of the airflow, it forms a water mist and is sprayed onto the vibrating plate 410. During the process of the vibrating plate 410 turning the soil, the curing agent sprayed onto the soil at the same time as the soil is turned will be added to the soil evenly, thereby improving the uniformity of the solidified soil mixture.

[0047] The implementation principle of a mobile mixing device for fluidized solidified soil according to an embodiment of this application is as follows: A vibratory plate 410 is installed on the support frame 110 to prepare the fluidized solidified soil. First, the solidified soil is transported to the vibratory plate 410 using a first conveyor. When the first motor 331 drives the stirring rod 320 to rotate and stir the existing solidified soil raw materials in the mixing bucket 310, the stirring rod 320 will push the vibratory plate 410 to swing left and right. Soil debris will move to the upper surface of the soil under the vibration of the vibratory plate 410. Then, the second motor 43... 1. By using the second motor 431 to drive the bidirectional lead screw 432 to rotate, the two crushing plates 434 can be moved closer to each other, so that the two crushing plates 434 can crush the soil and debris, and then pour it into the storage hopper for storage. This reduces the possibility of the presence of soil and debris affecting the quality of the fluidized solidified soil. At the same time, by using the setting of the air jet 532, during the process of the vibrating plate 410 vibrating and turning the soil, the solidifying agent is sprayed onto the soil at the same time as the soil is turned, so that the solidifying agent is added evenly to the soil, thereby improving the uniformity of the solidified soil mixture.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
