Description

Material mixing device for construction

Technical Field

The utility model belongs to the technical field of material stirring devices, in particular to a material stirring device for building construction.

Background Art

The most commonly used material on construction sites is concrete, which is composed of cement, sand, aggregates and other additives. In order to ensure that the various ingredients in the concrete are evenly mixed to obtain consistency and strength, a mixing device is needed to mix the concrete.

In a Chinese patent with publication number CN214163486U, a material mixing device for construction is mentioned. The utility model rotates the fixing pin out of the fixing hole, so that the connecting column and the fixing ring lose their limiting effect, pushes the connecting column or the telescopic drive device to move or shakes the hand crank to make the connecting column slide along the strip hole, that is, the rotating plate rotates around its axis, so that the discharge hole on the rotating plate is opposite to the discharge hole on the bottom plate, and the material in the mixing chamber can enter the discharge funnel below through the discharge hole to realize discharge.

However, the utility model only considers whether there will be any residue on the circular part of the mixing barrel. However, the discharge section of most mixing devices is constructed into a cone shape in order to improve the discharge efficiency. The utility model only stirs the circular part of the mixing barrel and scrapes and cleans its inner wall. The diameter of the stirring paddle of the utility model is only suitable for the circular part of the mixing barrel. The diameter of the stirring paddle is larger than the diameter of the conical discharge section. Therefore, it is difficult for the stirring paddle of the utility model to enter the conical discharge section to stir the concrete inside the discharge section. Secondly, when the concrete is discharged through the conical discharge section, the concrete will still adhere to the inner wall of the discharge section. A long-term vicious cycle will cause undesirable phenomena such as slow discharge rate.

The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

As shown in Figures 1 to 6:

Embodiment 1: The utility model provides a material mixing device for construction, including a main body mechanism 100, the main body mechanism 100 includes a mixing barrel 101, a material discharge section 102 is provided at the lower end of the mixing barrel 101, the material discharge section 102 is constructed as a cone, and a sealing cover 104 is provided at the upper end of the mixing barrel 101.

As can be seen from the above, by installing the bottom cover 103 at the bottom end of the unloading section 102 to seal the bottom end of the unloading section 102, and then pouring the concrete raw materials into the mixing barrel 101, covering it with the sealing cover 104, and using the sealing cover 104 to seal the open end of the mixing barrel 101.

A driving motor 207 is fixedly installed on the upper surface of the lifting plate 203, and the output shaft end of the driving motor 207 passes through the lifting plate 203, and a transmission wheel 1 is fixedly installed on the end thereof, and a transmission wheel 2 is fixedly installed on the outer side of the stirring shaft 204, and the outer sides of the transmission wheel 1 and the transmission wheel 2 are connected through a transmission belt 208.

As can be seen from the above, by starting the drive motor 207 to drive the transmission belt 208, and then drive the stirring shaft 204 to rotate, the stirring shaft 204 and the stirring blade 205 can rotate in the mixing barrel 101 to stir the concrete raw materials inside the mixing barrel 101. During the stirring process, the scraper 206 slides on the inner wall of the mixing barrel 101, so as to scrape off the concrete attached to the inner wall of the mixing barrel 101.

By starting the telescopic cylinder 202 to drive the lifting plate 203 to move up and down, the rotating component and the cleaning mechanism 300 can be driven to move up and down, so that the position of the rotating component and the cleaning mechanism 300 inside the mixing barrel 101 can be adjusted, and deep mixing can be performed at different positions. In the process of the rotating component and the cleaning mechanism 300 being lifted and lowered, the concrete can be driven to be mixed vertically, thereby increasing the sufficiency of the concrete mixing and then improving the uniformity of the concrete mixing.

Embodiment 3: This is the third embodiment of the utility model, including a cleaning mechanism 300, including a material discharge tray 301 rotatably mounted inside the lower end of the material discharge section 102, a support tube 302 is fixedly mounted inside the material discharge tray 301, and a scraper assembly is arranged outside the support tube 302.

The scraper assembly includes a fixed cylinder 303 fixedly installed on the outer surface of the support cylinder 302, a plurality of connecting frames 304 are evenly fixedly installed on the outer surface of the fixed cylinder 303, a plurality of connecting frames 304 are rotatably connected inside with rotating shafts 305, a plurality of rotating shafts 305 are fixedly installed on the outer surfaces with rotating rods 306, a plurality of rotating rods 306 are rotatably installed at the front ends with scraper plates 307, and a plurality of scraper plates 307 are in contact with the inside of the unloading section 102.

Support rods 310 are rotatably installed inside the support frames 309, and the support rods 310 are rotatably connected to the rotating rods 306 respectively. A number of connecting rods 311 are evenly and fixedly installed on the outer surface of the sliding ring 308, and the number of connecting rods 311 are fixedly connected to the stirring shaft 204.

As can be seen from the above, the stirring shaft 204 rotates to drive the support cylinder 302 to rotate, and then the discharge plate 301 can rotate inside the stirring barrel 101, thereby driving the scraper assembly to rotate and stirring the material inside the discharge section 102.

After stirring, the bottom cover 103 is disassembled by rotating the bottom cover 103, and the concrete is discharged through the discharge tray 301. The user drives the lifting plate 203 down by starting the telescopic cylinder 202, so that the stirring shaft 204 moves downward in the support tube 302, and then uses the connecting rod 311 to push the sliding ring 308 to slide downward outside the support tube 302, so that the support rod 310 rotates to change the angle, drives the rotating rod 306 to rotate, and causes the scraper plate 307 to slide down along the inner wall of the tapered discharge section 102. In the process of sliding down, the concrete attached to the inner wall of the discharge section 102 can be scraped off, so that the concrete falls to the discharge tray 301 and is discharged from the discharge hole on the discharge tray 301. Then, the driving motor 207 is started to drive the rotating assembly and the cleaning mechanism 300 to rotate and change the position of the scraper assembly. By further repeating the above steps, different positions inside the discharge section 102 can be cleaned. At the same time, when rotating, the scraper 206 rotates to further scrape off the concrete attached to the inner wall of the mixing barrel 101, and the concrete falls to the unloading section 102 for discharge. By setting the above structure, firstly, the concrete on the inner wall of the unloading section 102 can be stirred, and secondly, the scraper plate 307 slides down along the tapered inner wall of the unloading section 102, so that the concrete attached to the inner wall of the unloading section 102 can be cleaned and scraped off. The rotation of the scraper 206 cleans and scrapes off the concrete attached to the inner wall of the mixing barrel 101, which can avoid the waste of concrete and can avoid the concrete from sticking to the inner wall of the mixing barrel 101 and the inner wall of the unloading section 102, causing the concrete to solidify. The long-term solidification of multiple layers of concrete affects the use of the mixing device and reduces the use efficiency. Finally, when the scraper plate 307 scrapes downward, it will generate a certain extrusion force on the concrete, which can accelerate the rate of concrete discharge.
