Description

Technical Field

[0001] This utility model relates to the field of concrete batching technology, specifically to a scraping device for a concrete batching machine. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. Concrete typically refers to cement concrete, also known as ordinary concrete, which uses cement as the cementing material, sand and gravel as aggregates, and water in a specific ratio. In special engineering projects, admixtures and additives are added to concrete during construction to improve its properties such as frost resistance and crack resistance. Since additives have finer particles, they need to be pre-mixed and thoroughly mixed with sand and gravel to prevent fine particles from flowing through the sand and gravel gaps and accumulating at the bottom of the mixing bin, thus affecting the mixing effect.

[0003] In the prior art, publication number "CN220638408U" discloses a scraping device for a concrete batching machine, including a frame. A hopper is fixedly installed on the inner wall of the frame, and a moving mechanism is provided on the top of the frame. A driving mechanism is provided on the moving mechanism. When cleaning the hopper, water is transported through a first hollow rod to the inside of a second hollow rod via an external water pipe connected to a rotary joint. The water pressure pushes a third hollow rod to slide outward inside the second hollow rod, causing a nozzle to extend from the inside of the second hollow rod and spray the inner wall of the hopper. At the same time, the driving mechanism drives the first hollow rod to rotate inside the hopper for uniform spraying of the inner wall. The moving mechanism drives the first hollow rod to move up and down to further uniformly spray the inner wall of the hopper. After cleaning the inner wall of the hopper, a first spring drives the third hollow rod and the nozzle to return to their original positions, thereby achieving the purpose of cleaning the inner wall of the hopper.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the aforementioned device and existing technology, when powder is fed into a square hopper for mixing, due to the special internal cavity of the square hopper, the mixing blades inside the square hopper cannot reach all positions within the square hopper cavity. A large amount of mixed powder will accumulate in the right-angled area of ​​the square hopper. Excessive accumulation of powder will cause a large amount of mixed powder to solidify and adhere to the inner cavity of the square hopper, which is difficult to remove. The solidified powder will further reduce the internal volume of the square hopper, affecting the mixing efficiency of the powder. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5 This utility model provides a technical solution:

[0033] Example 1: A scraping device for a concrete batching machine: including a mixing box 1, a fixing frame 2, a supporting column 3 and a storage bin 4. The supporting column 3 is installed in the bottom area of ​​the mixing box 1, and the supporting column 3 is set in several groups at intervals. The storage bin 4 is installed between several groups of supporting columns 3. The fixing frame 2 is installed in the top area of ​​the mixing box 1. The mixing box 1 is provided with a mixing chamber 11.

[0034] The concrete powder mixing and proportioning anti-powder sticking and scraping unit is set between the fixed frame 2 and the mixing box 1. It is used to stir and proportion the mixed powder inside the mixing box 1, and scrape off the powder sticking inside the mixing box 1 during the proportioning process.

[0035] The concrete powder mixing and proportioning anti-powder sticking and scraping unit includes a mixing section, which includes a rotating electric shaft 21. The rotating electric shaft 21 is installed in the top area of ​​the fixed frame 2. A mixing main shaft 22 is installed on the rotating end of the rotating electric shaft 21. An annular disk 23 is sleeved on the surface of the mixing main shaft 22. An installation cavity 24 is provided on the surface of the annular disk 23. An electric hinge 25 is installed inside the installation cavity 24. A rotating swing arm 7 is installed on the rotating end of the electric hinge 25. A transverse lever 8 is installed on one side of the rotating swing arm 7. A mixing bottom rod 9 is installed at the bottom of the mixing main shaft 22. A bottom lever 91 is installed at the bottom of the mixing bottom rod 9. The bottom lever 91 is set in several groups at intervals. A lever 91 has a levering slope 92 at the bottom.

[0036] The concrete powder mixing ratio anti-powder sticking scraping unit also includes a material removal section, which includes a diversion block 71. The diversion block 71 is installed in the bottom area of ​​the rotating swing arm 7. The surface of the diversion block 71 is provided with diversion holes 72. Reinforcing ribs 82 are installed on both sides of the transverse deflector plate 8. A material removal scraper 81 is installed at one end of the transverse deflector plate 8.

[0037] In this embodiment, the bottom area of ​​the material-pushing inclined surface 92 of the bottom paddle 91 is inserted into the material discharge hole 12. The bottom paddle 91 will follow the rotation of the mixing bottom rod 9 to mix and stir the powder inside the material discharge hole 12. When the mixing main shaft 22 rotates, the rotating arm 7 of the annular disk 23 area installed on the mixing main shaft 22 rotates synchronously. The transverse paddle plate 8 installed at one end of the rotating arm 7 will mix and stir the powder in the mixing chamber 11, ensuring that the powder in the mixing chamber 11 and the material discharge hole 12 area is fully mixed and proportioned, and ensuring the proportioning efficiency of concrete powder.

[0038] A discharge hole 12 is provided at the bottom of the mixing chamber 11, and a powder mixing and proportioning closed discharge guide unit is provided at the bottom area of ​​the discharge hole 12.

[0039] The powder mixing and proportioning closed feeding guide unit includes a closed part, which includes a top frame 41. The top frame 41 is installed on the top of the storage bin 4. An electric drive push rod 42 is installed on the top of the top frame 41. A movable column 6 is installed on the movable end of the electric drive push rod 42. An arc-shaped top block 61 is provided on the top of the movable column 6. The movable column 6 and the arc-shaped top block 61 are movably inserted into the feeding hole 12.

[0040] The powder mixing and proportioning closed feeding guide unit also includes a flow guide section, which includes a feeding shell 5. The feeding shell 5 is installed on the top of the top frame 41. The movable column 6 and the arc-shaped top block 61 move through the top of the feeding shell 5. The surface of the feeding shell 5 is provided with a flow guide slope 51.

[0041] In this embodiment, the movable column 6 and the arc-shaped top block 61 are inserted into the top of the feeding shell 5 under the drive of the electric drive push rod 42. The arc-shaped top block 61 will fit against the top of the feeding shell 5. When the powder in the area of ​​the feeding hole 12 falls, the powder can fall into the storage bin 4 under the guidance of the arc-shaped top block 61 and the guide slope 51, thereby ensuring the conveying efficiency of the powder.

[0042] Working Principle: During operation, the operator pours the required proportions of concrete powder into the mixing tank 1. The mixing chamber 11 inside the mixing tank 1 is a circular cavity. After the powder is fully added to the mixing chamber 11, the operator can rotate the drive shaft 21. When the drive shaft 21 rotates, it drives the mixing main shaft 22 and the mixing bottom rod 9 to rotate. The mixing bottom rod 9 has a bottom lever 91 installed near the top of the discharge hole 12. The bottom lever 91 has a tilting slope 9... 2. The bottom area will be inserted into the discharge hole 12. The bottom paddle 91 will follow the rotation of the mixing bottom rod 9 to mix and stir the powder inside the discharge hole 12. When the mixing main shaft 22 rotates, the rotating arm 7 of the annular disk 23 area installed on the mixing main shaft 22 will rotate synchronously. The horizontal paddle 8 installed at one end of the rotating arm 7 will mix and stir the powder in the mixing chamber 11 to ensure that the powder in the mixing chamber 11 and the discharge hole 12 area is fully mixed and proportioned, and to ensure the proportioning efficiency of concrete powder.

[0043] When the transverse deflector plate 8 rotates, the scraper 81 installed on one side of the transverse deflector plate 8 can scrape the inner cavity of the mixing chamber 11 as it rotates with the transverse deflector plate 8. When the scraper 81 is in the initial position, part of the scraper 81 will remain in contact with the inner wall of the mixing chamber 11. As the powder mixing ratio proceeds, the viscosity of the powder increases. In order to further ensure the mixing effect of the powder in the mixing chamber 11, the electric hinge 25 can be driven. The rotating end of the electric hinge 25 will drive the rotating arm 7 to rotate downward. The downward rotation of the rotating arm 7 will pressurize the area of ​​the transverse deflector plate 8, so that the scraper 81 at the bottom of the transverse deflector plate 8 can be further pressurized to remove the sticky powder attached to the inner cavity of the mixing chamber 11, ensuring that the powder inside the mixing chamber 11 is fully mixed.

[0044] After the powder is fully mixed, the electric drive push rod 42 can be driven to retract and reset. When the moving end of the electric drive push rod 42 descends, it will drive the movable column 6 and the arc-shaped top block 61 to move out of the discharge hole 12. At this time, the discharge channel in the area of ​​the discharge hole 12 is opened. The movable column 6 and the arc-shaped top block 61 will be inserted into the top of the discharge shell 5 under the drive of the electric drive push rod 42. The arc-shaped top block 61 will fit against the top of the discharge shell 5. When the powder in the area of ​​the discharge hole 12 falls, the powder can fall into the storage bin 4 under the guidance of the arc-shaped top block 61 and the guide slope 51, thereby ensuring the conveying efficiency of the powder.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
