Description

Technical Field

[0001] This utility model belongs to the field of asphalt concrete production technology, specifically relating to a temporary storage hopper device. Background Technology

[0002] Asphalt concrete, also known as asphalt aggregate, is a mixture made by manually selecting mineral aggregates, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., with a certain proportion of road asphalt materials, and mixing them under strictly controlled conditions. In the actual production process of asphalt concrete, the raw materials are often temporarily stored in a storage hopper before the mixing stage.

[0003] The existing temporary storage hopper has the following problems: 1. It is impossible to weigh the raw materials in the temporary storage hopper, which affects the accuracy of the raw material weight measurement; 2. It is difficult to determine whether the raw materials were properly added to the temporary storage hopper in the previous production stage; 3. It is difficult to determine whether the raw materials in the temporary storage hopper have been completely discharged, which requires manual inspection.

[0004] Therefore, it is necessary to design a temporary storage hopper device with weighing function. Utility Model Content

[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, this embodiment designs a temporary storage hopper device, including a hopper mounting base 7, a temporary storage hopper 1, a guide chute 6, a weighing sensor 3, and other components.

[0026] The temporary storage hopper 1 adopts a conical structure. The top of the temporary storage hopper 1 is provided with an upward-facing feed inlet, and the bottom of the temporary storage hopper 1 is provided with a downward-facing discharge outlet. When in use, the temporary storage hopper 1 is installed above the hopper mounting base 7.

[0027] The arm 2 is fixedly connected to the outside of the temporary storage bucket 1, and the arm 2 adopts a frame structure.

[0028] The arm 2 is connected to the outside via a weighing sensor 3; the weighing sensor 3 weighs the arm 2 and the temporary storage hopper 1 while also providing support for both, and a weighing sensor 3 is installed at each of the four corners of the arm 2.

[0029] A temporary material valve plate 8 is provided at the discharge port at the lower part of the temporary storage hopper 1. The temporary material valve plate 8 is a long strip structure. Both ends of the temporary material valve plate are fixedly connected to the shaft at the discharge port through separate valve plate connecting arms. The shaft is rotatably connected to the temporary storage hopper. After the temporary material valve plate 8 rotates, it can offset the corresponding discharge port or block the discharge port of the temporary storage hopper 1. The temporary storage hopper 1 is rotatably connected to the temporary material valve plate through the valve plate connecting arms, so that the weight of the raw material at the valve plate can be transferred to the temporary storage hopper 1, thereby facilitating accurate measurement by the weighing sensor.

[0030] An outer cover 5 is provided around the discharge port of the temporary storage hopper 1. The outer cover 5 is used to cover the gap between the guide chute 6 and the discharge port of the temporary storage hopper 1, thereby achieving a dustproof effect. The outer end of the shaft at the discharge port of the temporary storage hopper 1 extends out of the outer cover 5, and the outer end of the shaft is vertically fixedly connected to the control arm 10. The control arm 10 is connected to a valve plate actuator 11. The valve plate actuator 11 can be a telescopic hydraulic cylinder or a telescopic electric cylinder. The cylinder body of the telescopic hydraulic cylinder or the telescopic electric cylinder is rotatably connected to the outer side wall of the temporary storage hopper 1, and the telescopic rod of the telescopic hydraulic cylinder or the telescopic electric cylinder is rotatably connected to the end of the control arm 10. This allows the valve plate actuator 11 to control the rotation of the shaft through the control arm 10, thereby driving the temporary storage valve plate 8 to move. Through the movable connection between the storage valve plate and the temporary storage hopper 1, the opening and closing control of the discharge port is realized.

[0031] When the temporary storage valve plate 8 is moved away from directly below the discharge port of the temporary storage hopper 1, the discharge port is opened, allowing the raw material in the temporary storage hopper 1 to fall into the guide chute 6 provided below the temporary storage hopper 1. The upper end of the guide chute 6 is located directly below the discharge port of the temporary storage hopper 1, and the lower end of the guide chute 6 extends to the side of the hopper mounting base 7.

[0032] A vibration motor 4 is fixed on the outer wall of the temporary storage hopper 1 to vibrate the temporary storage hopper 1 so that all the raw materials in the temporary storage hopper 1 can be discharged.

[0033] One or more hopper installation stations can be set on the top of the hopper mounting base 7, and each hopper installation station is equipped with a temporary storage hopper 1. When the left and right sides of the hopper mounting base 7 are equipped with separate mixing drums, hopper installation stations can be set on the top of the hopper mounting base 7. The lower ends of the guide chute 6 of the two hopper installation stations face opposite directions so that they face the mixing drums.

[0034] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
