[0001] The present application relates to the technical field of equipment for preparing concrete by dumping recycled aggregate, and in particular to equipment for preparing concrete by dumping recycled aggregate. Background Art

[0002] With the acceleration of urbanization, construction waste is increasing, and the use of recycled aggregate has become the focus of industry attention. Recycled aggregate is solid waste that has been crushed, screened, graded, and then mixed in a certain proportion to meet different usage requirements. Recycled aggregate can be used to prepare concrete.

[0003] For example, a Chinese patent (publication number: CN215038918U) discloses a recycled aggregate preparation and mixing device, including a supporting component and a mixing barrel arranged inside the supporting component, and also includes: a feed hopper and a telescopic device, both of which are fixedly connected to the top of the mixing barrel, the outer wall of the feed hopper is connected to the mixing barrel through a reinforcing plate, the outer wall of the mixing barrel is connected to a feeding device, and the output end of the feeding device matches the top of the feed hopper; a transmission device, connected to the outer wall of the fixed block, and the outer wall of the slider is connected to a first elastic component; a material control device, connected to the outer wall of the transmission device, the material control end of the material control device cooperates with the feed hopper, and the inside of the mixing barrel is connected to a mixing device, which effectively avoids the occurrence of congestion inside the mixing barrel due to excessive or too much feeding, and at the same time, the cement remaining on the inner wall of the mixing barrel can be cleaned, thereby improving the practicality and work efficiency of the device.

[0004] However, the above-mentioned search patent still has some shortcomings. When it is used, it can feed intermittently, but the position of the feed port is fixed, which causes the equipment to be unable to evenly disperse the recycled aggregate inside the mixing barrel during feeding, increasing the mixing burden and causing certain inconveniences in use. Therefore, a device for preparing concrete by dumping recycled aggregate is proposed to solve the above-mentioned problems. Utility Model Content

[0011] Furthermore, a bracket seat is fixed to the bottom surface of the mixing bin, a discharge valve is fixed on the outer peripheral wall of the discharge pipe, and a glass observation window is fixed to the front surface of the mixing bin.

[0013] Furthermore, the feed bin is a circular bin which is hollow inside and open on the top, and the plurality of feed pipes are evenly distributed along the circumferential direction of the feed bin.

[0014] The above technical solution facilitates uniform distribution of multiple feed pipes, thereby improving the uniformity of recycled aggregate dispersion.

[0015] Furthermore, the material guide block is a circular block, the material guide groove is a conical groove, the feed hole is a circular hole, and the feed hole and the feed pipe are opposite to each other in the upper and lower directions.

[0016] By adopting the above technical solution, the conical groove is provided to facilitate the collection of recycled aggregate so that it can enter the feed hole better.

[0017] Furthermore, the top end of the central axis extends to the feed bin and the bottom end extends to the mixing bin. The transmission bin, the gear, and the mixing rod are all arranged in the mixing bin. The multiple mixing rods are evenly distributed along the central axis and the left and right sides of the mixing shaft.

[0019] Furthermore, the rack is arc-shaped, the transmission bin is a cylindrical bin body which is hollow inside and open at the bottom, and the transmission bin, the gear and the central axis are coaxial.

[0020] The adoption of the above technical solution facilitates the synchronous and coaxial rotation of the transmission bin, the gear and the rack, thereby facilitating transmission.

[0021] Furthermore, the top end of the stirring shaft extends into the transmission bin, and the two stirring shafts are respectively located on the left and right sides of the missing gear.

[0022] By adopting the above technical solution, the rack and the gear can be matched to allow the stirring shaft to intermittently reverse and rotate, thereby improving the stirring and mixing effect.
