In the figure: mixing tank 1, inclined rod 2, transition connecting rod 3, transverse strut 4, arc scraper 5, telescopic rod 6, oil cylinder 7, rotating shaft 8, lug plate strut 9, hydraulic oil pipe 10, lug plate Limiting slot 11, cross strut body 12.

Detailed ways

The technical solutions of the present utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

Embodiment: As shown in Figure 1 and Figure 2, a concrete mixer truck concrete waste scraping device, the mixing tank 1 is provided with a rotating shaft 8 extending out of the mixing tank 1, and the rotating shaft 8 is provided with an oil cylinder. Hydraulic oil pipe 10 that communicates with the 7-phase oil circuit. The rotating shaft 8 is provided with a pair of oil cylinders 7 which are symmetrically distributed and integrally sleeved with the rotating shaft 8. Both ends of the oil cylinder 7 are provided with transverse struts 4. Both ends are provided with an ear plate limiting groove 11 which is connected with the transition connecting rod 3 by inserting a pin shaft. Between the horizontal strut 4 and the oil cylinder 7, there are telescopic rods 6 that are movably nested and connected to the oil cylinder 7, and both ends of the horizontal strut 4 are provided with lug plate struts 9 that are integrated with the rotating shaft 8 in a vertical structure. Between the plate strut 9 and the transverse strut 4, there is an oblique rod 2 that is hingedly connected with the ear plate strut 9 to limit the position. Between the inclined rod 2 and the transverse strut 4, there is a transition link 3 that is pivotally hinged and limited with the inclined rod 2. The upper ends of the inclined rods 2 are provided with four circular arc scrapers 5 which are equally spaced and are in movable contact with the stirring tank body 1 . The upper ends of the transition connecting rods 3 are provided with circular arc scrapers 5 which are equidistant and in movable contact with the stirring tank body 1 . The upper ends of the transverse struts 4 are provided with circular arc scrapers 5 which are equidistant and in movable contact with the stirring tank 1 .

When scraps need to be scraped off in the mixing tank 1 , the telescopic rod 6 and the oil cylinder 7 are in a retracted state to ensure that the device enters the mixing tank 1 . After it is in place, the oil pressure is fed through the hydraulic oil pipe 10, so that the oil cylinder 7 drives the telescopic rod 6 to stretch synchronously. At this time, the horizontal strut 4 rises, and at the same time drives the inclined rod 2 and the transition link 3 to articulately unfold. When the arc scraper 5 is in contact with the spiral turntable in the mixing tank 1 at an interval, the hydraulic oil pipe 10 stops feeding oil, and the oil cylinder 7 performs a hydraulic lock-type pressure maintenance at the same time. Then the mixing tank 1 and the rotating shaft 8 rotate in the opposite direction, so that the concrete waste is effectively scraped off.

To sum up, the concrete waste scraping device of the concrete mixer truck has the characteristics of simple structure, convenient operation and good running stability. Solved the problem of residual agglomeration of concrete in the mixing tank. Improve the scraping effect and efficiency, and avoid residual agglomeration caused by the decrease of concrete mixing uniformity.
