[0003] Aggregate batching equipment mainly includes hoppers for holding aggregates and conveyor belts for transporting aggregates. Impurities may be introduced into the aggregates during daily transportation and storage; therefore, secondary screening is required when the aggregates enter the hoppers. Currently, secondary screening is mainly carried out by setting screens on the hoppers. However, the screens accumulate screened material during use, affecting normal aggregate screening and requiring regular manual cleaning, which impacts the continuous operation efficiency of aggregate batching. Based on these problems, this application proposes an aggregate batching device that can automatically clean the accumulated material on the screens. Utility Model Content

[0030] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:
[0031] Example:
[0032] like Figures 1 to 5 As shown, this utility model provides an aggregate batching device, including a frame 1 and a hopper 2 disposed on the frame 1, and a conveyor belt 3 disposed at the bottom of the frame 1 below the discharge port of the hopper 2. The conveyor belt 3 is a belt scale, which adopts an electric drum drive and frequency conversion speed control metering method. The speed of the electric drum is changed by the frequency converter to accurately change the speed of the belt scale. Since the conveyor belt 3 is prior art, its structure is not detailed.
[0033] The aggregate batching device of this utility model also includes:
[0034] Rotating plate 4 is rotatably located on one side of the upper end of the feeding hopper 2;
[0035] Screen 5 is fixedly installed on one side of the rotating plate 4;
[0036] The pushing mechanism 6 is located on the side of the hopper 2 and is connected to the rotating part 41 of the rotating plate 4;
[0037] The discharge channel 7 is located on one side of multiple hoppers 2. The driving mechanism 6 drives the rotating plate 4 to rotate, which in turn drives the screen 5 to rotate, so as to pour the excess material screened out by the screen 5 into the discharge channel 7 for discharge.
[0038] The aggregate batching device of this utility model is equipped with multiple feeding hoppers 2, and the multiple feeding hoppers 2 are fixedly supported by separately set frame bodies 1, so as to transport different materials to the mixing cylinder for mixing.
[0039] See Figure 3In this application, the screen 5 is fixed at an incline on the rotating plate 4. The connection between the screen 5 and the rotating plate 4 is at the upper incline of the screen 5 inside the feed inlet of the hopper 2, preventing the accumulation of screened materials exceeding the limit at the connection between the screen 5 and the rotating plate 4. The rotating plate 4 is inclined at the upper end of the feed hopper 2, so that the angle between the screen 5 and the rotating plate 4 is greater than 120 degrees. When the material exceeding the limit inside the screen 5 rotates, it is poured into the discharge channel 7.
[0040] See Figures 1 to 3 The pushing mechanism 6 of this application includes a telescopic rod 61 and a swing arm 62. The telescopic rod 61 is one of an electric push rod, a pneumatic push rod, and a hydraulic push rod. The rotating part 41 is a rod structure, which is hinged to the side plate of the hopper 2 and fixedly connected to one end of the swing arm 62 through the side plate. The other end of the swing arm 62 is hinged to the output end of the telescopic rod 61. The end of the telescopic rod 61 is hinged to the side of the hopper 2, so that the telescopic movement of the telescopic rod 61 controls the rotation of the rotating plate 4.
[0041] See Figure 1 The application specifies two sets of driving mechanisms 6, each located on one side of the hopper 2, to facilitate stable control of the rotating plate 4. Further details can be found in the following section. Figure 2 and Figure 6 as well as Figure 7 The feeding hopper 2 includes a first feeding hopper 21, a second feeding hopper 22 and a third feeding hopper 23. The second feeding hopper 22 does not have a pushing mechanism 6 on its two side walls. At this time, the swing arms 62 on one side of the first feeding hopper 21 and the third feeding hopper 23 are connected to the swing arms 62 on both sides of the second feeding hopper 22 through the connecting rod 63, so as to synchronously control the three rotating plates 4.
[0042] See Figure 1 In this application, baffles 51 are provided on both sides of the screen 5. When the rotating plate 4 rotates, the baffles 51 can prevent the material exceeding the limit value screened on the screen 5 from sliding off from both sides.
[0043] In one embodiment, such as Figure 5 As shown, the hopper 2 of this application is inclinedly equipped with a guide plate 201, which can reduce the impact of falling material on the conveyor belt 3. A discharge mechanism 8 is rotatably mounted on the discharge port 20 of the hopper 2 to control the discharge speed. The discharge mechanism 8 controls the discharge speed of the material in the hopper 2 by its rotation speed to achieve quantitative discharge; simultaneously, when the discharge mechanism 8 stops rotating, it closes the discharge port 20. Specifically, the drive motor 81 is connected to the rotating rod 82 through a reducer, and the drive motor 81 is a self-locking motor.
[0044] See Figure 5The material discharge mechanism 8 of this application includes a drive motor 81, a rotating rod 82 and a material discharge plate 83. The drive motor 81 is fixedly mounted on the side of the discharge port 20. The rotating rod 82 is rotatably mounted inside the discharge port 20 and connected to the output end of the drive motor 81. The material discharge plate 83 consists of multiple pieces, which are evenly distributed on the rotating rod 82 along the circumference.
[0045] In one embodiment, the application further includes a vibration motor, which is disposed on the side wall of the hopper 2.
[0046] The feeding hopper 2 of this application is mounted on the frame 1 on both sides by rollers, and the front and rear ends of the feeding hopper 2 are connected to the frame 1 by elastic elements. The feeding hopper 2 relies on the rollers on both sides to bear the overall weight, and in combination with the elastic elements and the horizontally set vibration motor, the feeding hopper 2 can vibrate in the horizontal direction.
[0047] Furthermore, as another embodiment, the hopper 2 is provided with an elastic element in the vertical direction and connected to the roller, so that the hopper 2 vibrates in multiple directions under the action of the multi-directional vibration motor. Furthermore, the elastic element can be used instead of the roller.
[0048] The elastic element in this application is a spring. One end of the spring is connected to the hopper 2, and the other end of the spring is connected to the frame 1. There are multiple springs. Specifically, there are 3-5 springs at both the front and rear ends.
