Description

Technical Field

[0001] The invention relates to the field of concrete mixers, in particular to a concrete mixer with a cleaning function. Background Art

[0002] Concrete is a general term for engineering composite materials that are cemented into a whole by cementitious materials. Concrete is everywhere in our lives, and concrete is a machine that mixes cement, sand and gravel aggregates and water into concrete mixture through a mixer. It is mainly composed of a mixing drum, a feeding and unloading mechanism, a water supply system, a prime mover, a transmission mechanism, a frame and a supporting device.

[0003] However, due to the rapid solidification of concrete in the prior art and the characteristics of adhesion and molding after mixing, during the mixing process, the concrete often adheres to the inner wall of the overall device. After a period of time, the concrete will completely solidify on the inner wall of the overall device, which not only affects the subsequent work, but also easily causes damage to the re-mixing or parts of the overall device. For this reason, after the work is completed, we usually need to clean and maintain the mixer. During cleaning, the inner wall of the mixer is difficult to clean, because the solidified concrete has the characteristics of a relatively hard texture. It is often necessary to manually go in and use a stone-breaking device and a hammer to break the concrete and then clean it finely. For this reason, we need to solve the problem of concrete adhesion and residue on the cylinder wall during the mixing process, and also solve the problem of how to conveniently clean the mixing parts. At the same time, in the subsequent fine cleaning process, most of the existing mixing devices on the market are suspended designs. When personnel enter to replace spare parts and overhaul, there are often certain risks due to the suspension design. Summary of the invention

During the rotation process, the stirring blades continuously rub the gaps between the scratching blades on the surface of the stirring rod, and the concrete materials adhered to the surface of the stirring blades are scratched. At the same time, the scratching blades continuously touch the inner wall of the mixing cylinder by means of axial rotation, and continuously contact and scratch the inner wall of the mixing cylinder. At the same time, the vertical scratching between the stirring blades and the scratching blades again avoids the adhesion of concrete on the side of the stirring blades.

The transmission motor inside the rotating box on the other side drives the rotating gear to rotate, and the transmission gear engaged with the transmission box rotates, driving the entire barrel to rotate, so that the inner wall of the mixing cylinder continuously tilts, rotates and falls in the process of contacting the concrete raw materials and the stirring blades, thereby increasing the stirring and mixing speed relative to it.

This concrete mixer with a cleaning function inverts the tilted mixing cylinder to clean the water, and the entire cylinder is tilted and rotated to allow the water used for cleaning to fully contact the inner wall of the cylinder. The stirring blades that contact the inner wall of the entire device cooperate with the scratching blades to mix the water with the concrete residue on the inner wall of the entire mixing cylinder.

The support frame 26 is semicircular in side view and the inner side is engaged with the rotating groove 17. The driving motor 21 drives the driving gear 22 to rotate, so that the auxiliary gear 24 rotates threadedly to drive the threaded rod 23 to rise and fall, and the cylinder body is driven to rise in the process of lifting. At the same time, the rotating shaft 25 drives the support frame 26 to raise the mixing cylinder 1. The process adapts to the inclination angle of the barrel body and is raised from the ground to avoid driving the entire mixing cylinder 1 to move from the transmission suspension mode, so that the stability of the overall device is better.

[0023] like Figure 2 - Figure 7 As shown, a transmission box 27 is movably provided on the inner wall of the rotating box 20, and rotating shafts 28 are fixedly provided on both sides of the transmission box 27. Both sides of the rotating shaft 28 are connected and fixed to the inner wall of the rotating box 20, and a transmission motor 29 is fixedly provided on one side of the inner wall of the transmission box 27. A rotating gear 30 is fixedly provided on one side of the transmission motor 29. The gear ring 18 penetrates the transmission box 27 and is engaged.

The transmission motor 29 inside the rotating box 20 drives the rotating The movable gear 30 rotates, and the transmission gear engaged with the transmission box 27 rotates, driving the entire cylinder to rotate, so that the inner wall of the mixing cylinder 1 is continuously tilted, rotated and dropped in the process of contacting the concrete raw materials and the stirring blade 4, thereby increasing the stirring and mixing speed relative thereto. At the same time, the entire cylinder is tilted and rotated, so that the water used for cleaning is fully in contact with the inner wall of the cylinder, and the stirring blade 4 contacting the inner wall of the entire device cooperates with the scratching blade 13 to mix the water with the concrete residue on the inner wall of the entire mixing cylinder 1. The stirring blade 4 is designed to maintain the T-shaped quick-release principle, and cooperates with the scratching blade 13 to scratch the inner wall and the inner wall of the mixing cylinder 1 for rapid cleaning with water, thereby avoiding the need to enter the inner wall of the device to thoroughly clean or crush the solidified concrete during the traditional concrete mixing process.

[0024] Working principle: concrete raw materials are placed through the feeding trough 14, and the stirring motor 8 drives the first elliptical gear 9 to rotate. The first elliptical gear 9 drives the second elliptical gear 10 to rotate axially around the fixed point of the second elliptical gear 10, so that the stirring rod 12 performs a uniaxial rotation like a gyroscope. During the rotation process, the stirring blade 4 continuously rubs the gap between the scratching blades 13 on the surface of the stirring rod 12, and the concrete material adhered to the surface of the stirring blade 4 is scratched. At the same time, the scratching blade 13 continuously touches the inner wall of the mixing tank 1 by axial rotation, The inner wall of the mixing cylinder 1 is constantly in contact and scraped, and at the same time, the stirring blade 4 and the scraping blade 13 are vertically scraped, which again avoids the adhesion of concrete on the side of the stirring blade 4. Combined with the rotation of the main stirring rod 12, the self-cleaning of various stirring components and the avoidance of stirring influence caused by continuous adhesion of concrete are realized during the stirring process. The concrete raw materials are placed through the feeding trough 14, and the driving motor 21 drives the driving gear 22 to rotate, so that the auxiliary gear 24 rotates and drives the threaded rod 23 to rise and fall. During the lifting process, the cylinder body is driven to rise. The rotating shaft 25 drives the support frame 26 to raise the mixing cylinder 1 to adapt to the tilt angle of the barrel body. The transmission motor 29 inside the rotating box 20 on the other side drives the rotating gear 30 to rotate, and the transmission gear engaged with the transmission box 27 is rotated, driving the entire barrel body to rotate, so that the inner wall of the mixing cylinder 1 is continuously tilted, rotated and dropped in the process of contacting the concrete raw materials and the stirring blades 4, increasing the mixing speed relative thereto, and fixing and supporting the entire mixing cylinder 1 from the bottom at the same time, which is more stable and has better maintenance and repair of the entire device than the transmission suspension type mixing method. Conveniently, the tilted mixing cylinder 1 is inverted to remove water for cleaning, and the entire cylinder is tilted and rotated, so that the water used for cleaning is fully in contact with the inner wall of the cylinder, and the stirring piece 4 that contacts the inner wall of the entire device cooperates with the scratching piece 13 to mix the water with the concrete residue on the inner wall of the entire mixing cylinder 1. The stirring piece 4 maintains the T-shaped quick-release principle in design, and cooperates with the scratching piece 13 to scratch the inner wall and the water to quickly clean the inner wall of the mixing cylinder 1, thereby avoiding the need to enter the inner wall of the device to thoroughly clean or break the solidified concrete during the traditional concrete mixing process.
