Concrete mixture weighing mechanism

The utility model relates to the technical field of concrete detection, and discloses a concrete mixture weighing mechanism which comprises a weight detector, a knocking mechanism is arranged on the upper surface of the weight detector, and the knocking mechanism is composed of a side plate, a transmission rod, an eccentric wheel, a connecting rod, an impact block, a telescopic rod, a knocking plate and a limiting block. A side plate is fixedly connected to the upper surface of the weight detector, and transmission rods are rotationally connected to the surfaces of the inner walls of the two sides of the side plate. According to the concrete mixture weighing mechanism, through the arrangement of the transmission rod, the eccentric wheel, the impact block and the knocking plate, the capacity cylinder can be continuously knocked, gas in concrete in the capacity cylinder can be removed, the concrete detection effect is guaranteed, during use, a concrete mixture is added into the capacity cylinder, a motor is sta
