Description

Technical Field

[0001] This utility model relates to the field of building material processing equipment technology, and in particular to a green and environmentally friendly mixing device for building material processing. Background Technology

[0002] Green and environmentally friendly building materials refer to building materials that meet specific environmental protection standards during production, use, and disposal, are environmentally friendly and harmless to human health, and have characteristics such as resource conservation and energy efficiency.

[0003] Some building materials require mixing solids and liquids to combine the advantages of each material and compensate for the shortcomings of individual materials. However, during mixing, some materials may stick to the mixing shaft. To ensure that the mixing is not affected by residual materials in the next mixing, the mixing shaft needs to be disassembled and cleaned in its dead corners. Some existing equipment uses bolts to fasten the mixing shaft, which is convenient for fixing the mixing shaft and making it more stable during mixing. However, disassembly and installation require a lot of time and manpower. Therefore, this application provides a green and environmentally friendly mixing device for building material processing to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a green and environmentally friendly mixing device for processing building materials. By setting a fixing component, the mixing shaft can be automatically locked and released. When the mixing cover is closed, the pressure block presses down to trigger the fixing block to insert into the slot, which automatically fixes the mixing shaft. After the mixing cover is opened, the spring returns to release the fixing block, and the mixing shaft can be directly pulled out for cleaning. This facilitates the cleaning and maintenance of the mixing shaft and solves the problem of time-consuming disassembly of the mixing shaft in existing green and environmentally friendly mixing devices for processing building materials.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A green and environmentally friendly mixing device for processing building materials includes a mixing tank, a mixing cover rotatably connected to the top of the mixing tank, a mixing motor installed at the bottom of the mixing tank, a discharge port installed at the bottom of the mixing tank, a drive bevel gear installed at the output end of the mixing motor, a mixing shaft inserted into the bottom of the mixing tank, and a fixing component. The fixing component is used to realize the automatic locking and releasing of the mixing shaft, and the fixing component is connected to the mixing shaft.

[0007] Optionally, the fixing component includes a pressure block, which is slidably connected inside the stirring shaft. A first return spring is fixedly connected between the bottom of the pressure block and the inner wall of the top of the stirring shaft. A pressing rod is fixedly connected to the bottom of the pressure block. A fixing block is slidably connected to the inner wall of the stirring shaft at the end away from the pressure block. A second return spring is fixedly connected between the fixing blocks.

[0008] Optionally, the end of the extrusion rod away from the pressure block has a tapered structure and is adapted to the side wall of the fixed block that is close to it.

[0009] Optionally, a spiral stirring rod and an inclined blade stirring rod are welded to the outer surface of the stirring shaft, and the corners of the spiral stirring rod and the inclined blade stirring rod are chamfered.

[0010] Optionally, a driven bevel gear is rotatably connected to the bottom of the mixing tank, and the driven bevel gear meshes with the driving bevel gear.

[0011] Optionally, a connecting shaft is fixedly connected to the top of the driven bevel gear, and both the bottom of the stirring shaft and the top of the connecting shaft are toothed and mesh with each other.

[0012] Optionally, a guide rod is provided inside the stirring shaft near the connecting shaft. The guide rod has a tapered structure, and a slot is provided at the position corresponding to the connecting shaft. The guide rod is inserted into the slot.

[0013] Optionally, a slot is provided at the position corresponding to the slot of the fixing block, and the fixing block is inserted into the slot.

[0014] Optionally, the outer walls on both sides of the fixing block are provided with sliding rods, and guide grooves are provided at the corresponding positions of the sliding rods and the inner walls of the guide rods, and the sliding rods are slidably connected inside the guide grooves.

[0015] Optionally, the bottom of the stirring cover is provided with a rotating groove, and the inner contour of the rotating groove matches the outer contour of the top of the stirring shaft, and the stirring shaft is inserted into the rotating groove.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, the automatic locking and releasing of the stirring shaft is achieved by setting a fixing component. When the stirring cover is closed, the pressure block presses down to trigger the fixing block to insert into the slot, automatically fixing the stirring shaft. After the stirring cover is opened, the spring resets and the fixing block disengages. At this time, the stirring shaft can be directly pulled out for cleaning, which is convenient for cleaning and maintenance of the stirring shaft.

[0018] With rounded teeth at the bottom of the mixing shaft, when installing the mixing shaft, simply align the guide rod with the slot, and the mixing shaft will move down due to gravity and automatically engage. The internal fixing blocks of the mixing shaft will correspond to the internal slots of the connecting shaft. The rounded corners at the meshing points of the mixing shaft and the connecting shaft reduce wear and extend the service life of the equipment. At the same time, the spiral mixing rod and the inclined blade mixing rod welded to the outer surface of the mixing shaft have chamfered corners, which facilitates the breaking up of building materials that are stuck together, allowing the building materials to be fully mixed and improving the uniformity and quality of the mixture.

[0034] like Figure 1 and Figure 6As shown, this utility model provides a green and environmentally friendly mixing device for processing building materials, including a mixing tank 1. A mixing cover 2 is rotatably connected to the top of the mixing tank 1. A sealing ring is provided at the contact position between the inner ring of the mixing cover 2 and the mixing tank 1. The sealing ring is a prior art technology and will not be described in detail. It can effectively prevent the internal building materials from escaping during mixing. A mixing motor 3 is provided at the bottom of the mixing tank 1, and a discharge port 4 is provided at the bottom of the mixing tank 1. A butterfly valve is provided at the discharge port 4. The butterfly valve is a prior art technology and will not be described in detail. A drive bevel gear 301 is installed on the output shaft of the mixing motor 3. A mixing shaft 5 is inserted into the bottom of the mixing tank 1. A fixing component is used to realize the automatic locking and releasing of the mixing shaft 5. The fixing component is connected to the mixing shaft 5. By setting the fixing component, the automatic locking and releasing of the mixing shaft 5 is realized. When the mixing cover 2 is closed, the pressure block 6 presses down to trigger the fixing block 7 to insert into the slot, automatically fixing the mixing shaft 5. After the mixing cover 2 is opened, the spring returns to release the block, and the mixing shaft 5 can be directly pulled out for cleaning.

[0035] In this embodiment, as Figures 1 to 6 As shown, the fixing assembly includes a pressure block 6, which is slidably connected inside the stirring shaft 5. A first return spring 601 is fixedly connected between the bottom of the pressure block 6 and the inner wall of the top of the stirring shaft 5. The bottom of the stirring cover 2 has a rotating groove, and the inner contour of the rotating groove matches the outer contour of the top of the stirring shaft 5. When the stirring cover 2 covers the top of the stirring tank 1, the top of the stirring shaft 5 is inserted into the rotating groove, thereby causing the pressure block 6 to move down until it is flush with the top of the stirring shaft 5. A pressing rod 602 is fixedly connected to the bottom of the pressure block 6. Figure 4 As shown, a fixing block 7 is slidably connected to the inner wall of the end of the stirring shaft 5 away from the pressure block 6. Two fixing blocks 7 are slidably installed on the inner wall of the stirring shaft 5. The inner walls of the two fixing blocks 7 are respectively connected to the two ends of the second return spring 701, which pulls the fixing blocks 7 inward. The end of the extrusion rod 602 away from the pressure block 6 is tapered and is adapted to the side wall of the fixing blocks 7 that is close to each other. Sliding rods 702 are provided on both outer walls of the fixing blocks 7. The inner wall of the guide rod 503 is provided with a guide groove, and the sliding rod 702 is slidably connected inside the guide groove. The pressure block 6 moves down, causing the extrusion rod 602 to move down, thereby causing the fixing blocks 7 to move outward along the guide groove.

[0036] In this embodiment, as Figures 1 to 6As shown, the driven bevel gear 8 and the driving bevel gear 301 mesh with each other. Starting the stirring motor 3 can drive the driving bevel gear 301 and the driven bevel gear 8 to rotate. A connecting shaft 801 is fixedly connected to the top of the driven bevel gear 8. The bottom of the stirring shaft 5 and the top of the connecting shaft 801 are both toothed, and the meshing teeth are rounded to reduce wear. They mesh with each other. A guide rod 503 is provided inside the end of the stirring shaft 5 near the connecting shaft 801. The guide rod 503 has a conical structure. A slot 9 is provided on the connecting shaft 801. The guide rod 503 is inserted into the slot 9. When it is necessary to install the stirring shaft 5, simply align the guide rod 503 with the slot. The stirring shaft 5 will move down due to gravity. The rounded meshing teeth at the bottom of the stirring shaft 5 will contact the meshing teeth at the top of the connecting shaft 801. It will move down along its curved surface until it is fully meshed. At this time, the stirring shaft 5 and the connecting shaft 801 will mesh with each other. The internal fixing block 7 of the stirring shaft 5 will correspond to the position of the internal slot 10 of the connecting shaft 801. Specifically, the fixing block 7 is provided with a protrusion 703, which can be inserted into the groove 10. Closing the mixing cover 2 can drive the fixing block 7 to be inserted into the groove and fix the mixing shaft 5. The outer surface of the mixing shaft 5 is welded with a spiral mixing rod 501 and an inclined blade mixing rod 502. The corners of the spiral mixing rod 501 and the inclined blade mixing rod 502 are chamfered to facilitate the breaking up of the building materials that are stuck together.

[0037] The workflow of the technical solution provided by this utility model is as follows:

[0038] In use, first place the building materials to be mixed inside the mixing tank 1, then tighten the mixing cover 2. At this time, the top of the mixing shaft 5 will be inserted into the rotating groove at the bottom of the mixing cover 2, thereby driving the pressure block 6 to move down to be flush with the top of the mixing shaft 5, and then driving the extrusion rod 602 to move down. The conical structure at the bottom of the extrusion rod 602 extrudes the fixing block 7. The fixing block 7 moves outward along the guide groove and is inserted into the slot 10. The fixing block 7 will fix the mixing shaft 5, connecting the mixing shaft 5 to the connecting shaft 801. At this time, the mixing motor 3 can be started. The mixing motor 3 will drive the driving bevel gear 301 and the driven bevel gear 8 to rotate. Since the mixing shaft 5 and the connecting shaft 801 are meshed by rounded corner teeth, the mixing will be driven... When shaft 5 rotates, the spiral stirring rod 501 and the inclined blade stirring rod 502 welded to the surface of the stirring shaft 5 will mix the building materials. The corners of the spiral stirring rod 501 and the inclined blade stirring rod 502 are chamfered to facilitate the breaking up of the building materials that are stuck together. After mixing is completed, the building materials can be discharged through the butterfly valve set at the bottom of the mixing tank 1. When it is necessary to disassemble the stirring shaft 5 for cleaning, the stirring cover 2 can be opened. At this time, the pressure block 6 is not squeezed. The first return spring 601 will drive the pressure block 6 and the squeezing rod 602 to move upward. The second return spring 701 will drive the protrusion 703 of the fixing block 7 to disengage from the slot 10 opened inside the connecting shaft 801. The stirring shaft 5 can be directly pulled out for cleaning.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
