Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, and in particular to a concrete preparation mixing equipment. Background Technology

[0002] Concrete: refers to a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water in a certain proportion. It is widely used in civil engineering.

New materials are then added again for repeated preparation. If the concrete cannot be discharged in time, the device needs to wait. This method results in low efficiency and inconvenience for operators.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a concrete preparation and mixing equipment. Utility Model Content

The diameter of the third gear 10 is larger than that of the second gear 9, and the diameter of the second gear 9 is larger than that of the fourth gear 12.

[0035] In order to solve the problem of mixing raw materials, multiple connecting rods 13 are fixedly provided on the outside of the vertical rod 11, and connecting rods 14 are fixedly provided at the bottom of the multiple connecting rods 13. Inclined plates 15 are fixedly provided at the bottom of the connecting rods 14.

[0036] To address the issue of the sleeve 16's ability to rotate, a sleeve 16 is movably connected to the inner wall of the preparation cylinder 1 via a bearing. The sleeve 16 is positioned between the first partition 5 and the second partition 7. A rack 17 is fixedly installed inside the sleeve 16. A rotating shaft 18 is movably connected between the first partition 5 and the second partition 7 via a bearing. A fifth gear 19 is fixedly installed outside the rotating shaft 18.

[0037] In order to solve the problem of the rotating shaft 18 being able to rotate, a first pulley is fixedly provided on the outside of the rotating shaft 18, and a second pulley is fixedly provided on the outside of the rotating shaft 18. A belt 20 is provided between the first pulley and the second pulley, and the first pulley and the second pulley are connected by the belt 20.

[0038] In order to solve the problem of concrete entering the first partition 5, the sleeve 16, the first partition 5 and the second partition 7 are all provided with through grooves 21. The top of the first partition 5 is fixedly provided with a collection hopper 22, which is located between the first partition 5 and the through groove 21 of the sleeve 16.

[0039] In order to protect the structure such as the first gear 6, a protective box 23 is fixedly installed on the top of the first partition 5. The first gear 6, the rotating shaft 18 and the third gear 10 are all located inside the protective box 23. Support rods 24 are fixedly installed at the four corners of the bottom of the preparation cylinder 1. Two feed hoppers 25 are fixedly installed on the top of the preparation cylinder 1. A discharge pipe is fixedly installed at the bottom of the preparation cylinder 1.

[0040] Working Principle: In use, this invention is first connected to an external power source. Raw materials are fed into the preparation cylinder 1 through two feed hoppers 25. Simultaneously, the motor 2 is started. The motor 2 drives the rotating rod 3 to rotate, which in turn drives multiple mixing rods 4 outside the rotating rod 3 to rotate. The rotation of the rotating rod 3 also drives the first gear 6 to rotate, which in turn drives the second gear 9 to rotate. The second gear 9 then drives the rotating shaft 8 to rotate, which in turn drives the third gear 10 to rotate. The third gear 10 then drives the fourth gear 12 to rotate, which in turn drives the vertical rod 11 to rotate. The rotating shaft 8 drives the connecting rod 13 to rotate, which in turn drives the connecting rod 14 to rotate, and the connecting rod 14 to rotate the inclined plate 15. The rotation of the inclined plate 15 allows for mixing of the raw materials at the top of the first partition 5. Because the first gear 6 and the second gear 9 have the same diameter, the third gear 10 has a larger diameter than the second gear 9, and the second gear 9 has a larger diameter than the fourth gear 12, the rotating shaft 8 and the rotating rod 3 rotate at the same speed. However, the vertical rod 11 rotates at a speed greater than the rotating shaft 8, meaning the vertical rod 11 rotates at a speed greater than the rotating rod 3. When the rotating shaft 8 rotates, it also drives the first pulley to rotate. The first pulley, via the belt 20, carries... The second pulley rotates, which in turn drives the fifth gear 19 to rotate. Since the fifth gear 19 meshes with the rack 17, and the sleeve 16 is connected to the inner wall of the preparation cylinder 1 via bearings, the rotation of the fifth gear 19 also drives the rack 17 to rotate, which in turn causes the sleeve 16 to rotate. When the sleeve 16 rotates, it drives the through groove 21 on the sleeve 16 to rotate, thus blocking the through groove 21 of the second partition 7 at the top, preventing the raw material at the top of the second partition 7 from entering the first partition 5. When the sleeve 16 slowly rotates one revolution, the raw material at the top of the second partition 7 will be mixed. At this point, the first partition 5 and the second partition 7... The channels 21 on plate 7 and sleeve 16 will gradually overlap, and the mixed concrete at the top of the second partition 7 will enter the top of the first partition 5 through the channel 21. The mixing rod 4 can slowly stir the concrete at the top of the first partition 5 to prevent it from solidifying. When the inclined plate 15 rotates one or two times, the concrete on the second partition 7 will basically enter the first partition 5. As the sleeve 16 continues to rotate, it will block the channel 21 on the second partition 7. At this time, the raw materials can be added into the preparation cylinder 1 again through the feed hopper 25 for mixing. The concrete on the first partition 5 can be discharged through the discharge pipe.

[0041] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
