Technical Field

[0001] The present application relates to the technical field of concrete mixing devices, and in particular to a concrete mixing device. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion, and obtained by mixing. It is also called ordinary concrete and is widely used in civil engineering.

[0003] After searching the patent document with the announcement number CN219054838U, it was found that the patent document uses a motor to drive a rotating rod to rotate, the rotating rod drives a cross block to rotate, the cross block drives a stirring rod to rotate around the rotating rod, the stirring rod stirs the material to prepare concrete, and at the same time, a scraper is used to scrape the inner wall of the tank to scrape off the adsorbed concrete. In this process, the tank will also be rolled to allow it to be fully stirred.

[0004] In the above patent, after the scraper has been scraping against the inner wall of the tank for a long time, the port of the scraper is worn. After long-term use, a gap is formed between the scraper and the inner wall of the mixing drum, and the inner wall of the mixing drum cannot be effectively scraped, resulting in poor scraping of concrete. In addition, the existing concrete mixing requires workers to load the materials. Due to the high height of the mixing drum, loading the materials is time-consuming and labor-intensive. Therefore, the present application provides a concrete mixing device to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the present application provides a concrete mixing device.

[0006] The concrete mixing device provided in this application adopts the following technical solution:

[0007] A concrete mixing device comprises a bottom plate and a mixing drum;

[0008] A loading assembly is arranged at the upper end of the bottom plate, and the loading assembly includes four arc-shaped support columns, and an oblique upward loading frame is fixedly installed at one end of the four arc-shaped support columns, a conveyor belt is arranged inside the oblique upward loading frame, and a plurality of loading plates are fixedly installed outside the conveyor belt, and a conveying motor is fixedly installed outside the oblique upward loading frame;

One end of the output shaft of the mixing motor passes through the interior of the mixing drum, and a rotating column is fixedly installed at one end of the output shaft, and a plurality of stirring rods are fixedly installed on the outside of the rotating column, and three cleaning components are arranged on the outside of the rotating column.

[0010] Preferably, one of the cleaning components comprises two guide plates, and the two guide plates are fixed on the outside of the rotating column near the upper and lower ends.

[0011] Preferably, a connecting plate is provided on one side of the guide plate, and a scraping plate is fixedly installed on one side of the two connecting plates. The scraping plate is made of rubber material, and one end of the scraping plate is in contact with the inner wall of the mixing drum.

[0012] Preferably, fixed blocks are fixedly installed near the middle of the upper and lower ends of the guide plate, and a screw is threaded through one side of the fixed block. A protective cover is provided on the outside of the guide plate, a rubber column is fixedly installed on one side of the protective cover, and the screw is located on the inner side of the protective cover, and a socket matching the rubber column is opened on one side of the connecting plate.

[0013] Preferably, a through hole is opened on one side of the connecting plate, and T-shaped blocks are fixedly installed on the upper and lower inner walls of the through hole, and one end of the guide plate is sleeved inside the through hole.

[0014] Preferably, the upper and lower ends of the guide plate are both provided with T-slots matching the T-block, and one end of the screw rod is movably engaged inside the connecting plate.

[0015] In summary, the present application includes the following beneficial technical effects: by setting up a feeding assembly, starting a conveying motor, and allowing the conveyor belt to drive the feeding plate to move, workers only need to place the concrete raw materials on the conveyor belt between the two feeding plates, and finally allow the concrete raw materials to fall freely into the interior of the mixing drum, and the assembly makes concrete feeding more convenient and saves time and effort;

[0016] Through the cleaning component that is set up, after the stirring motor drives the rotating column to rotate, the guide plate and the connecting plate rotate, and the scraper plate scrapes the inner wall of the mixing drum. When the scraper plate is worn, the protective cover is pulled outward to expose the screw, and the two screws are rotated so that the screws push the connecting plate to move toward the inner wall of the mixing drum. After the scraper plate fits the inner wall of the mixing drum, the screw is stopped. Due to the effect of the T-block, the connecting plate is always mounted on the outside of the guide plate. This component can always scrape the inner wall of the mixing drum, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
