Description

Technical Field

[0001] This invention relates to the field of soil mixing equipment technology, specifically a mixing equipment for solidifying soil materials for highway subbase. Background Technology

[0002] In highway construction, mixing equipment for the solidification of subgrade soil is crucial for ensuring roadbed quality. This equipment, through innovative design of its separation and mixing mechanisms, achieves layered storage, uniform feeding, and efficient mixing of raw materials and cement, making it suitable for large-scale roadbed construction scenarios. Its core lies in the staggered groove design of the rotating disc and chassis to control the intermittent release of cement, combined with the pre-crushing and dispersion of raw materials by pressure plates and grinding blocks, improving mixing uniformity and production continuity. This is of great significance for ensuring the stability of highway subgrades and construction efficiency.

[0003] Traditional soil mixing equipment has significant shortcomings. In terms of feeding methods, traditional equipment often uses a single, centralized feeding process, leading to uneven mixing of raw materials and cement, easily forming lumps, requiring frequent shutdowns for manual intervention, and severely impacting construction efficiency. During the feeding process, the lack of a dynamic control mechanism allows cement to easily clump due to moisture absorption, clogging the feeding channels and causing uncontrolled mixing ratios, affecting the quality of the solidified soil. Structurally, traditional mixing drums lack pre-crushing and dispersing devices at the bottom, allowing lumpy raw materials to directly enter the mixing area, increasing mixing resistance and making it difficult to ensure uniformity, resulting in inconsistent strength of the solidified soil. Furthermore, traditional equipment cannot achieve continuous operation, requiring intermittent shutdowns for feeding, which cannot meet the large-scale, high-efficiency construction demands of highway construction. Moreover, high manual operation costs and difficulty in accurately controlling the mixing ratio restrict the quality and progress of subbase construction. Summary of the Invention

[0004] (a) Technical problems to be solved This invention provides a mixing and stirring device for solidified soil material in the subbase of highways, which solves the problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a mixing and stirring device for solidifying subbase soil of a highway, comprising a mixing drum, a fixing ring fixedly connected to the top outer surface of the mixing drum, a fixing frame fixedly connected to the upper surface of the fixing ring, the fixing frame being positioned directly above the mixing drum, and further comprising: a mixing mechanism fixedly installed inside the mixing drum; and a separation mechanism fixedly installed on the mixing mechanism; wherein the mixing mechanism includes a motor fixedly installed on the upper surface of the middle part of the fixing frame, the output end of the motor being rotatably connected to a rotating shaft, a mixing rod fixedly connected to the bottom of the rotating shaft, the mixing rods being arranged in groups of three, and the mixing rods being arranged at fixed intervals around the central axis of the rotating shaft in three groups.

[0006] According to one embodiment of the present invention, the separation mechanism includes a separation ring, which is fixedly connected to the inner surface of the middle part of the stirring cylinder. A material leakage groove is formed through the upper surface of the separation ring. A separation cylinder is fixedly connected to the side surface of the separation ring away from the stirring cylinder. The separation cylinder and the stirring cylinder are arranged with the same central axis.

[0007] According to one embodiment of the present invention, a base plate is fixedly connected to the bottom inner surface of the separating cylinder, a first misalignment groove is formed through the upper surface of the base plate, a rotating disk is rotatably connected to the upper surface of the base plate, the rotating disk is fixedly sleeved on the middle outer surface of the rotating shaft, a second misalignment groove is formed through the upper surface of the rotating disk, and the second misalignment groove is arranged in the same shape as the first misalignment groove.

[0008] According to one embodiment of the present invention, a lever is fixedly connected to the top outer surface of the rotating shaft. The levers are arranged in groups of three, and the levers are arranged at fixed intervals around the central axis of the rotating shaft. The levers are disposed inside the separating cylinder.

[0009] According to one embodiment of the present invention, a connecting frame is fixedly connected to the top of the separating cylinder, a transfer wheel is rotatably connected to the inner surface of the top of the connecting frame, the transfer wheel is rotatably connected to the lower surface of the top of the fixed frame, a connecting wheel is rotatably connected to the side of the transfer wheel away from the connecting frame, and the connecting wheel is fixedly sleeved on the outer surface of the top of the rotating shaft.

[0010] According to one embodiment of the present invention, a groove is formed on the top inner surface of the stirring cylinder, and a sliding rod is fixedly connected in the groove. A pressure plate is fixedly connected to the bottom outer surface of the separation cylinder. The pressure plate is inclined and the side of the pressure plate away from the separation cylinder is attached to the top inner surface of the stirring cylinder.

[0011] According to one embodiment of the present invention, a mating plate is elastically slidably sleeved on the slide rod, the mating plate is inclined, the bottom surface of the mating plate is initially attached to the upper surface of the pressure plate, and the bottom of the pressure plate is attached to the upper surface of the separation ring.

[0012] According to one embodiment of the present invention, a dispersion cover is fixedly connected to the bottom of the separation cylinder. The bottom of the dispersion cover is funnel-shaped. A fixing rod is fixedly connected to the top outer surface of the dispersion cover. The end of the fixing rod away from the dispersion cover is fixedly connected to the inner surface of the stirring cylinder. A gap is provided between the bottom of the dispersion cover and the stirring cylinder. A grinding block is provided above the bottom of the dispersion cover. The bottom surfaces on both sides of the grinding block are inclined. A connecting rod is fixedly connected to the grinding block. The end of the connecting rod away from the grinding block is fixedly connected to the outer surface of the rotating shaft through the gap between the dispersion cover and the stirring cylinder.

[0013] According to one embodiment of the present invention, an aggregate block is fixedly connected to the end of the stirring rod away from the rotating shaft. The cross-section of the aggregate block is triangular, and the surface of the end of the aggregate block away from the stirring rod is attached to the inner bottom surface of the mixing drum. The raw materials required for solidifying the soil are added into the mixing drum, and the motor is started. The motor drives the rotating shaft to rotate, which in turn drives the stirring rod at its bottom to rotate, thereby fully mixing the raw materials of the solidified soil. Before adding the raw materials, cement from the raw materials is introduced into the separation drum, and other raw materials are introduced into the gap between the mixing drum and the separation drum. When the motor starts, the connecting wheel at the top of the rotating shaft drives the transfer wheel to rotate, thereby driving the transfer frame to rotate. Finally... The separation cylinder begins to rotate, and the rotation direction of the separation cylinder is opposite to that of the rotating shaft. When the separation cylinder rotates, it drives the pressure plate on its outer surface to rotate, causing the pressure plate to rotate within the gap between the separation cylinder and the mixing cylinder. The rotation of the pressure plate agitates the raw materials between the separation cylinder and the mixing cylinder, allowing the raw materials to enter the bottom of the mixing cylinder evenly through the material leakage groove on the separation ring. At the same time, the rotation of the rotating shaft drives the rotating disk to rotate, causing the rotating disk to rotate continuously on the upper surface of the base plate. Ultimately, the second misalignment groove on the rotating disk intermittently overlaps with the first misalignment groove on the base plate, so that the cement intermittently and evenly enters the bottom of the mixing cylinder through the first and second misalignment grooves.

[0014] (III) Beneficial Effects This invention provides a mixing and stirring device for solidifying the subbase soil of a highway. It has the following beneficial effects: (I) The mixing equipment for the solidification of the subbase of this highway can significantly improve the uniformity of mixing by uniformly feeding the raw materials and cement into the bottom of the mixing drum and then mixing them with the mixing rod at the bottom of the rotating shaft. This avoids the problem of raw materials clumping and being unable to be mixed evenly when they are directly put into the mixing drum at once. At the same time, the uniform feeding method can also greatly improve the working continuity of this equipment, thereby ensuring the continuity of production and avoiding the problem of intermittent shutdown for feeding required by existing mixing equipment. When the rotating shaft rotates, it will drive the actuating rod to rotate synchronously, thereby continuously agitating the cement inside the separation drum during equipment operation. This greatly improves the smoothness of cement passing through the No. 1 and No. 2 misalignment grooves, avoids the blockage problem caused by cement standing for a long time, and at the same time maintains the uniformity of cement, greatly improving the subsequent mixing effect of raw materials.

[0015] (II) The mixing equipment for the subbase solidification soil of this highway intermittently compresses the mating plate as the pressure plate rotates and agitates the raw materials. Under pressure, the mating plate moves upward along the slide bar within the groove. When the pressure plate reaches the bottom of the mating plate, it eventually misaligns with it, causing the mating plate to return to its original position under elastic force. This achieves intermittent compression and contact between the raw materials and the bottom surface of the mating plate during agitation. The mutual compression between the pressure plate and the mating plate crushes and breaks up the lumpy sand in the raw materials, significantly improving efficiency. The continuous flow of raw materials through the discharge trough prevents blockages. As the pressure plate rotates, it continuously cleans the upper surface of the separation ring from its bottom, further enhancing the ring's anti-clogging performance. Furthermore, the pressure plate's movement creates cavities behind it, causing raw materials at the top to fall to the bottom. This significantly improves the overall flowability of the raw materials between the separation and mixing drums, achieving pre-mixing and greatly increasing the subsequent mixing efficiency and production capacity.

[0016] (III) In the mixing equipment for the subbase solidification soil of this highway, when the raw material enters below the separation ring through the leakage chute, it will stay above the dispersion hood. At this time, the rotation of the shaft will drive the grinding blocks to rotate continuously above the dispersion hood through the connecting rod. The grinding blocks on both sides of the bottom surface will further crush and grind the raw material, further reducing the possibility of raw material agglomeration. Finally, the powdered raw material will leak through the gap between the dispersion hood and the mixing drum to the bottom of the mixing drum, further improving the mixing efficiency. The continuous rotation of the connecting rod can also continuously clean the gap between the dispersion hood and the mixing drum, thereby greatly reducing the problem of blockage. When the raw material leaks to the bottom of the mixing drum, it will be dispersed at the edge. At this time, the rotation of the aggregate block with a triangular cross section will push the leaked raw material to the middle of the mixing drum through its inclined surface. This, together with the continuously falling cement, further improves the mixing effect, thereby greatly improving the production quality of the solidified soil. Attached Figure Description

The toggle levers 58 are arranged in three groups with a fixed spacing around the central axis of the rotating shaft 42. The toggle levers 58 are located inside the separation cylinder 53.

[0024] A connecting frame 59 is fixedly connected to the top of the separating cylinder 53. A transfer wheel 510 is rotatably connected to the inner surface of the top of the connecting frame 59. The transfer wheel 510 is rotatably connected to the lower surface of the top of the fixed frame 3. A connecting wheel 511 is rotatably connected to the side of the transfer wheel 510 away from the connecting frame 59. The connecting wheel 511 is fixedly sleeved on the outer surface of the top of the rotating shaft 42.

[0025] A groove 512 is provided on the inner surface of the top of the mixing drum 1. A slide rod 513 is fixedly connected in the groove 512. A pressure plate 514 is fixedly connected to the outer surface of the bottom of the separation drum 53. The pressure plate 514 is inclined and the side of the pressure plate 514 away from the separation drum 53 is attached to the inner surface of the top of the mixing drum 1.

[0026] A mating plate 515 is elastically slidably sleeved on the slide rod 513. The mating plate 515 is inclined. Initially, the bottom surface of the mating plate 515 is attached to the upper surface of the pressure plate 514, and the bottom of the pressure plate 514 is attached to the upper surface of the separation ring 51.

[0027] A dispersion cover 516 is fixedly connected to the bottom of the separation cylinder 53. The bottom of the dispersion cover 516 is funnel-shaped. A fixing rod 517 is fixedly connected to the top outer surface of the dispersion cover 516. The end of the fixing rod 517 away from the dispersion cover 516 is fixedly connected to the inner surface of the stirring cylinder 1. A gap is provided between the bottom of the dispersion cover 516 and the stirring cylinder 1. A grinding block 518 is provided above the bottom of the dispersion cover 516. The bottom surfaces on both sides of the grinding block 518 are inclined. A connecting rod 519 is fixedly connected to the grinding block 518. The end of the connecting rod 519 away from the grinding block 518 is fixedly connected to the outer surface of the rotating shaft 42 through the gap between the dispersion cover 516 and the stirring cylinder 1.

[0028] An agglomerate block 520 is fixedly connected to one end of the stirring rod 43 away from the rotating shaft 42. The cross-section of the agglomerate block 520 is triangular, and the surface of the end of the agglomerate block 520 away from the stirring rod 43 is attached to the bottom inner surface of the stirring drum 1.

[0029] During operation, the raw materials required for solidifying the soil are put into the mixing drum 1, and the motor 41 is started. The motor 41 drives the rotating shaft 42 to rotate, which in turn drives the mixing rod 43 at its bottom to rotate, thereby fully mixing the raw materials of the solidifying soil. Before the raw materials are put in, the cement in the raw materials is introduced into the separation drum 53, and other raw materials are introduced into the gap between the mixing drum 1 and the separation drum 53. When the motor 41 starts, it drives the transfer wheel 510 to rotate through the connecting wheel 511 at the top of the rotating shaft 42, thereby driving the transfer frame to rotate, and finally causing the separation drum 53 to start rotating. The rotation direction of the separation drum 53 is opposite to that of the rotating shaft 42. When the separation drum 53 rotates, it drives the pressure plate 514 on its outer surface to rotate, thereby increasing the pressure. Plate 514 rotates within the gap between separation cylinder 53 and mixing cylinder 1, thereby agitating the raw materials between them through the rotation of pressure plate 514. This allows the raw materials to evenly enter the bottom of mixing cylinder 1 through the material leakage groove 52 on separation ring 51. Simultaneously, the rotation of shaft 42 drives rotating disk 56 to rotate, causing it to continuously rotate on the upper surface of base plate 54. Ultimately, the second misalignment groove 57 on rotating disk 56 intermittently overlaps with the first misalignment groove 55 on base plate 54, ensuring that cement intermittently and evenly enters the bottom of mixing cylinder 1 through the first and second misalignment grooves 55 and 57. The evenly entering raw materials and cement at the bottom of mixing cylinder 1 allows the rotating shaft 42 to achieve a smooth flow. The bottom stirring rod 43 significantly improves the uniformity of mixing, avoiding the problem of raw materials clumping and uneven mixing caused by directly adding them into the mixing drum 1. Simultaneously, the uniform feeding method greatly improves the continuity of operation, ensuring continuous production and avoiding the need for intermittent shutdowns for material feeding required by existing mixing equipment. Furthermore, the rotation of the rotating shaft 42 synchronously drives the actuating rod 58, continuously agitating the cement inside the separation drum 53 during operation. This significantly improves the smoothness of cement passing through the first and second misalignment grooves 55 and 57, preventing blockages caused by prolonged cement stagnation and maintaining cement uniformity, thus greatly improving subsequent mixing of raw materials. The effect is that when the pressure plate 514 rotates and agitates the raw material, it intermittently squeezes the mating plate 515. Under pressure, the mating plate 515 begins to move upwards along the slide rod 513 within the slide groove 512. When the pressure plate 514 reaches the bottom of the mating plate 515, it finally misaligns with it, meaning the mating plate 515 returns to its original position under the action of elasticity. This achieves the effect that when the pressure plate 514 agitates the raw material, it pushes the raw material to intermittently press against the bottom surface of the mating plate 515. The mutual squeezing action between the pressure plate 514 and the mating plate 515 crushes the lumpy sand in the raw material, significantly improving the continuity of the raw material passing through the discharge chute 52 and preventing blockages in the discharge chute 52.As the pressure plate 514 rotates, it continuously cleans the upper surface of the separation ring 51 through its bottom, further improving the anti-clogging performance of the separation ring 51. When the pressure plate 514 pushes the raw material, it continuously creates cavities behind it, causing the raw material at the top to fall to the bottom. This significantly improves the overall flowability of the raw material between the separation cylinder 53 and the mixing cylinder 1 when the pressure plate 514 agitates the raw material, thereby achieving pre-mixing of the raw material and greatly improving the subsequent mixing efficiency and production capacity. When the raw material enters below the separation ring 51 through the discharge chute 52, it stays above the dispersion cover 516. At this time, the rotation of the shaft 42 drives the grinding block 518 to continuously grind the grinding block 518 on the dispersion cover 516 via the connecting rod 519. The mixing drum 1 rotates, further pulverizing and grinding the raw materials through the inclined grinding blocks 518 on both sides of the bottom surface, further reducing the possibility of raw material agglomeration. Ultimately, the powdered raw materials leak through the gap between the dispersion cover 516 and the mixing drum 1 to the bottom of the mixing drum 1, further improving the mixing efficiency. The continuous rotation of the connecting rod 519 also continuously cleans the gap between the dispersion cover 516 and the mixing drum 1, significantly reducing clogging problems. When the raw materials leak to the bottom of the mixing drum 1, they disperse at the edges. At this time, the rotation of the triangular cross-section aggregate block 520 continuously pushes the leaked raw materials to the center of the mixing drum 1 through its inclined surface, thereby further improving the mixing effect in conjunction with the continuously falling cement, thus significantly improving the production quality of the solidified soil material.
