[0002] Subgrade fill material is used for filling and paving in subgrade construction. There are various types of subgrade fill material, one of which is volcanic ash fill material. Volcanic rock residual soil is formed by the accumulation of magma erupted from submarine volcanoes, and the excavated volcanic ash is a type of earthwork material. Volcanic ash fill material is prepared by mixing volcanic ash earthwork material with cement in a certain proportion, and then carrying out the mixing, leveling, compaction, and curing construction processes. Traditionally, when mixing volcanic ash earthwork material with cement, it is generally mixed inside a mixing tank, and the material is mixed using a geared motor driven by a motor shaft to finally reach the finished product.

[0003] In the above operation, since the earthwork material and cement are mixed together in the mixing drum, it takes a long time to mix the materials evenly. The earthwork material or cement material cannot be dispersed when it is poured, which reduces the mixing time. In the preparation of volcanic ash roadbed filler, there is no material drum design to disperse the volcanic ash, which is a shortcoming. Existing methods for preparing roadbed fill materials have the problem of lacking a mixing and preparation device with a material hopper design to disperse the raw materials. To address this, this application proposes a mixing and proportioning device for preparing volcanic rock residual roadbed fill materials. Utility Model Content

[0016] Please see Figures 1 to 5This utility model provides a technical solution: a mixing device for preparing volcanic rock residual roadbed filling material, including a mixing assembly for mixing volcanic rock residual roadbed filling material, comprising a mixing drum 11 and a support plate 12 fixed by bolts, a reduction mixing motor 13 and a spiral mixing shaft 14 connected by a coupling, the spiral mixing shaft 14 penetrating the support plate 12, the bottom end of the spiral mixing shaft 14 being located inside the mixing drum 11, the reduction mixing motor 13 driving the spiral mixing shaft 14 to rotate, the spiral mixing shaft 14 mixing the mixed roadbed raw materials inside the mixing drum 11 to achieve the purpose of preparing roadbed filling material, the support plate 12 serving to support and fix the support column 2; it also includes a feeding assembly, comprising the support column 2 and a top plate 3 fixed by bolts, and a material bucket 4 welded to the top plate 3, the material bucket 4 being in a stable state under the support and fixation of the fixed support column 2 and the top plate 3, the material bucket 4 being located on the upper side of the mixing drum 11. The material is placed in a way that facilitates the feeding of raw materials from the material tank 4 into the mixing tank 11 for mixing. A filter screen 8 is fixed to the bottom surface of the material tank 4 by bolts. The filter screen 8 disperses the raw materials, keeping them dispersed during feeding and feeding into the material tank 4 and preventing them from clumping together and increasing mixing time. The material tank 4 also includes a support assembly, including a reinforcing member 51 fixed to the material tank 4 by bolts, a stabilizing column 52 penetrating the reinforcing member 51, a welded cross arm 53, and a motor base 54. The reinforcing member 51 provides reinforcement. The system includes a support column 52, a cross arm 53, and a motor base 54 to support the geared mixing motor 13; it also includes a mixing assembly, including a sleeve 6 sleeved on the outside of the spiral mixing shaft 14, a cross bar 61 symmetrically installed on the outside of the sleeve 6, a mixing rod 7 and a scraper 10 connected in combination. When the geared mixing motor 13 drives the spiral mixing shaft 14 to rotate, the sleeve 6, the mixing rod 7 and the scraper 10 rotate with the spiral mixing shaft 14. The mixing rod 7 and the scraper 10 cause the raw materials inside the material bucket 4 to move, which is conducive to the discharge of raw materials.

[0017] In this embodiment, the material bucket 4 includes an inner ring 41, a guide ring 42, a bottom plate 43, and an outer ring 44. The guide ring 42 is a hollow conical structure with a sloping conical surface, which facilitates the flow of raw materials on its surface. The inner ring 41 is fixedly connected to the top plate 3. The bottom plate 43 is installed between the guide ring 42 and the inner ring 41. The bottom plate 43 has evenly distributed perforated grooves a and evenly distributed fan-shaped discharge grooves b. The raw materials stored inside the material bucket 4 can leak down from the perforated grooves a and discharge grooves b to disperse the raw materials and ensure that the raw materials are in a dispersed state. The filter screen 8 is located at the discharge groove b. The filter screen 8 is fan-shaped and has distribution rods 9 welded on both sides. The distribution rods 9 serve to distribute the raw materials discharged from the discharge groove b, thus preventing the raw materials from accumulating at the location of the filter screen 8.

[0018] In this embodiment, a connecting block is welded to the top of the stirring rod 7, one end of the crossbar 61 is inserted into the connecting block, the stirring rod 7 is perpendicular to the crossbar 61, the stirring rod 7 and the crossbar 61 are connected to form an integral structure, and the bottom end of the stirring rod 7 is inserted into the inside of the material bucket 4.

[0019] In this embodiment, a circular sleeve c is welded to one side of the scraper 10, and the bottom end of the stirring rod 7 is connected to the sleeve c by screws. The scraper 10 and the stirring rod 7 are connected in a combined manner, which facilitates disassembly and replacement of the scraper 10. An "L"-shaped material distribution column 101 is connected to the surface of the scraper 10. The material distribution column 101 plays a role in distributing materials. The scraper 10 scrapes the raw materials, and the material distribution column 101 disperses the raw materials, reducing the resistance caused by the agglomeration of raw materials on the scraper 10.

[0020] In this embodiment, the reinforcing member 51 includes an arc portion and a circular tube portion. The stabilizing column 52 passes through the circular tube portion and is perpendicular to the end of the horizontal arm 53. The arc portion of the reinforcing member 51 is welded to the mixing tank 11, and the circular tube portion is used to support and fix the stabilizing column 52.

[0021] Working principle and usage process of this utility model: The raw materials for preparing the roadbed are put into the mixing tank 11. When the manual operation of the reduction mixing motor 13 is running, the reduction mixing motor 13 drives the spiral mixing shaft 14 to rotate. The spiral mixing shaft 14 mixes the roadbed raw materials in the mixing tank 11 to achieve the purpose of preparing roadbed filling materials. The raw materials to be mixed are poured into the inside of the material bucket 4. When the spiral stirring shaft 14 stirs, the sleeve 6, stirring rod 7 and scraper 10 rotate with the spiral stirring shaft 14. The stirring rod 7 and scraper 10 cause the raw materials inside the material bucket 4 to move, which is conducive to the raw materials being discharged into the mixing bucket 11. When the raw materials are fed into the material bucket 4, the filter screen 8 plays a role in dispersing the raw materials, so that the raw materials fed into the material bucket 4 are in a dispersed state, avoiding the raw materials from clumping together and increasing the stirring time. The raw materials stored inside the material bucket 4 can leak down from the positions of the chute a and the discharge chute b to disperse the raw materials and ensure that the raw materials are discharged in a dispersed state. The material distribution rod 9 serves to distribute the material, thereby dispersing the raw material discharged from the feeding trough b and preventing the raw material from accumulating on the filter screen 8. In summary, this application provides a mixing device for preparing raw materials for volcanic rock residual roadbed filling. The mixing device has a material bucket 4 for dispersing the raw materials. When the deceleration mixing motor 13 drives the spiral mixing shaft 14 to mix the raw materials in the mixing bucket 11, the sleeve 6, the mixing rod 7, and the scraper 10 rotate with the spiral mixing shaft 14. The mixing rod 7 and the scraper 10 cause the raw materials inside the material bucket 4 to move, which is conducive to the raw materials being discharged into the mixing bucket 11. The filter screen 8 and the material distribution rod 9 disperse the raw materials, thus having the function of dispersing the raw materials.
