Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing and transportation, in particular to a waste scraping device for a concrete mixer truck. Background Art

[0002] After the concrete transport truck in the construction industry has completed unloading at the construction site, concrete is often adhered to the discharge plate. If it is not cleaned or cleaned incompletely, it will not only hinder the next unloading, but the remaining concrete will cause more concrete to adhere to the discharge plate. Therefore, the remaining concrete on the discharge plate needs to be cleaned. The traditional cleaning method is to flush it with a high-pressure water gun.

[0003] After searching, the application with patent application number CN202223087982.1 discloses a scraping device for concrete waste on a concrete mixer truck, including a conveying trough, two side surfaces of the conveying trough are fixedly connected with a slide groove, the inside of the slide groove is rotatably connected with a threaded rod, one end of the threaded rod passes through the slide groove and is connected with a driving mechanism, a moving block is threadedly connected with a side surface of the threaded rod, a scraper plate is fixedly connected with the inside of the moving block through a rotating shaft, a buckle strip is fixedly connected with one side surface of the scraper plate, and a limiting mechanism is provided on the upper surface of one end of the conveying trough;

[0004] Although the concrete waste scraping device of the concrete mixer truck drives the scraper plate to reciprocate in the conveying trough to clean the concrete adhered to the conveying trough, the scraper plate of the concrete waste scraping device of the concrete mixer truck is easily blocked by the concrete when moving, which easily causes the scraper plate to be damaged.

[0005] Therefore, we propose a waste scraping device for a concrete mixer truck. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a waste scraping device for a concrete mixer truck, which solves the problem that the scraping plate of the prior device is easily blocked by concrete when moving, which easily causes the scraping plate to be damaged.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a waste scraping device for a concrete mixer truck, comprising a feed trough;

[0008] A first installation box and a second installation box are symmetrically installed on both sides of the feed trough, and threaded rods and sliding rods are rotatably mounted inside the first installation box and the second installation box respectively through bearing rings. A motor is fixedly installed on the side of the first installation box, and the output end of the motor passes through the side wall of the first installation box and is fixedly connected to the threaded rod. A first scraper and a second scraper driven by the motor are arranged inside the feed trough, and the first scraper and the second scraper are respectively penetrated by a first groove and a second groove on the arc surface close to the feed trough.

[0009] Preferably, the outer surface of the threaded rod is threadedly sleeved with one end of the first U-shaped plate and the second U-shaped plate, the other ends of the first U-shaped plate and the second U-shaped plate are slidably sleeved on the outer surface of the sliding rod, and the bottom surfaces of the first U-shaped plate and the second U-shaped plate are respectively fixedly mounted with the first scraper and the second scraper, wherein the threaded rod is driven to rotate by a motor, and then the first scraper and the second scraper fixedly mounted on the bottom surfaces of the first U-shaped plate and the second U-shaped plate are driven to reciprocate inside the feed trough.

[0010] Preferably, the arc surfaces of the first scraper and the second scraper are in contact with the inner wall of the feed trough, and there are at least thirty evenly distributed first grooves and second grooves, and the first grooves and the second grooves are staggered, wherein the first grooves and the second scraper can be used to alternately scrape concrete inside the feed trough, thereby reducing the resistance of the concrete to the movement of the first scraper and the second scraper and facilitating the flushing of concrete on the surfaces of the first scraper and the second scraper.

[0011] Preferably, connecting rods are fixedly installed on the side walls of the first U-shaped plate and the second U-shaped plate, and the connecting rods are symmetrically distributed on both sides of the first U-shaped plate and the second U-shaped plate, wherein the first U-shaped plate and the second U-shaped plate are connected together by the connecting rods so that they move synchronously.

[0012] Preferably, a baffle is fixedly mounted on the side wall of the feed trough, and the baffle can prevent the concrete inside the feed trough from flowing out.

[0013] Preferably, a flushing pipe is fixedly mounted inside the baffle, and the flushing pipe is connected to a water source, wherein the surfaces of the feed trough, the first scraper and the second scraper can be flushed through the flushing pipe.

[0014] The utility model provides a waste scraping device for a concrete mixer truck, which has the following beneficial effects:

[0015] 1. The scraper device for a concrete mixer truck drives the first scraper and the second scraper to move back and forth along the inside of the feed trough through a motor to scrape the concrete inside the feed trough. Since the first groove and the second groove are alternately distributed, not only can the inside of the feed trough be fully cleaned, but also the resistance of the concrete to the movement of the first scraper and the second scraper is reduced, thus solving the problem that the scraper plate of the existing device is easily blocked by concrete when moving, which easily causes the scraper plate to be damaged;

[0016] 2. The waste scraping device of the concrete mixer truck can flush the surfaces of the feed trough, the first scraper and the second scraper through a flushing pipe. When the first scraper and the second scraper reciprocate inside the feed trough, the water flow sprayed from the flushing pipe will flush the concrete on the surfaces of the feed trough, the first scraper and the first groove, thereby preventing the concrete from adhering to the surfaces of the first scraper and the second scraper, thereby causing damage to the first scraper and the second scraper.
