Description

Technical Field

[0001] This application relates to the technical field of aggregate storage, and in particular to an aggregate storage device. Background Art

[0002] For the mixing of concrete products, it is usually produced by a mixing station. The mixing station is usually equipped with an aggregate bin for storage. After being conveyed by a conveyor belt to an aggregate hopper for weighing, it is then conveyed into a mixer for mixing.

[0003] In the prior art, CN111055383A discloses a folding mixing station, which includes an aggregate storage device, including an aggregate hopper and a folding conveyor belt mechanism. The aggregate hopper is of an inverted conical structure, and a discharge port is provided at the bottom of the inverted conical structure. The discharge port faces the conveyor belt, and a discharge valve is provided at the discharge port. Under the action of gravity and the conical guidance of the inverted conical structure, the aggregate will fall on the conveyor belt and be conveyed to the next process position by the conveyor belt; the conveyor belt of the aggregate storage device is in a folded form. In the folded state, the overall volume of the storage device can be reduced, which is convenient for the transfer and transportation of the device. In the folded state, a part of the structure of the conveyor belt needs to overlap above the aggregate hopper, that is, the height of the aggregate hopper needs to be lower than the height of the hinge point of the conveyor belt structure, which reduces the capacity space of the aggregate hopper. To solve this problem, usually a plurality of foldable side plates are provided on the peripheral side of the top of the aggregate hopper. When the conveyor belt is folded, the side plates are turned over to reduce the height of the aggregate hopper so that the conveyor belt can be overlapped and fixed on the aggregate hopper. However, since the aggregate is usually heavy, the pressure on the side plates in the accommodating space formed by the folded side plates is usually large, so the load-bearing capacity requirements for the folding structure are high, and the folded side plates are prone to damage or leakage of materials; if the position of the hinge point is increased, the conveying length will be increased, the conveying efficiency will be reduced, and it is not convenient for transfer; therefore, how to ensure effective folding transportation while increasing the storage capacity of the aggregate hopper is a technical problem that the storage device needs to focus on solving. Summary of the Utility Model

[0004] In order to ensure effective folding transportation while increasing the storage capacity of the aggregate bin, this application provides an aggregate storage device.

[0005] An aggregate storage device provided by this application adopts the following technical solutions:

[0006] An aggregate storage device includes a conveying mechanism and an aggregate bin. The conveying mechanism includes a conveying section, and the conveying section gradually slopes upward along the conveying direction. The conveying section includes a first conveying section and a second conveying section, and the first conveying section and the second conveying section are connected by a hinge assembly. A fixed base is provided on the first conveying section, and the aggregate bin is arranged above the first conveying section through the fixed base. The bottom of the aggregate bin abuts against the surface of the first conveying section, and the length direction of the bottom of the aggregate bin extends along the conveying direction of the first conveying section.

[0007] By adopting the above technical solution, the first conveying section and the second conveying section in the conveying mechanism are connected by a hinge assembly, so that the conveying mechanism is a foldable structure, which can make the overall aggregate storage device have a relatively reduced volume when moving, facilitating movement. The first conveying section of the conveyor belt is used to form part of the aggregate hopper, and the material output of the aggregate hopper is controlled by starting and stopping the conveyor belt, making full use of the length space in the conveying direction of the conveyor belt, improving the storage capacity of the hopper, and the stored aggregates can be spread out along the length direction of the conveyor belt, with the conveyor belt being evenly stressed, reducing the transmission load, also reducing the concentration degree of aggregates in the storage space, reducing the stress on the aggregate bin, and improving the structural stability of the aggregate bin. At the same time, due to the conveying power of the conveyor belt, the aggregates in the aggregate bin can be kept in an inclined movement state. The aggregates have an upward inclined movement in the aggregate bin and a downward sliding movement tendency due to gravity. The combination of multiple movement states reduces the compaction phenomenon caused by long-term static accumulation of aggregates, facilitating the output of aggregates.

[0016] Preferably, the support member includes a connecting rod fixedly connected to both sides of the frame and a first oblique side roller and a second oblique side roller respectively arranged on the two connecting rods, the first oblique side roller and the second oblique side roller are arranged to be inclined downward toward the middle of the transmission belt, and the first oblique side roller and the second oblique side roller are arranged to be relatively inclined.

[0017] By adopting the above technical solution, a first inclined side roller and a second inclined side roller are provided so that the middle part of the conveyor belt is affected by the gravity of the aggregate, and the cross-section is arranged in an arc shape to form an aggregate cavity for accommodating the aggregate, thereby reducing the possibility of the aggregate slipping and detaching from the two sides during the conveying process, so as to improve the corresponding conveying stability.

[0018] Preferably, the hinge assembly includes two hinge rods fixedly connected to the first frame and the second frame respectively and a rotating rod rotatably connected to the two hinge rods, and the height of the hinge rods is lower than the height of the transmission belt at the edge.

[0019] By adopting the above technical solution, by providing an articulated rod and a rotating rod, since the height of the articulated rod is lower than the height of the transmission belt at the edge, the possibility of the articulated rod touching the conveyor belt can be reduced, and the stretching of the transmission belt after rotation can also be reduced.

[0020] Preferably, a first support rod is detachably connected to one end of the second frame away from the first frame, a second support rod is fixedly connected to one end of the first frame away from the aggregate bin, the second support rod is fixedly connected to the bracket, a support plate is arranged on the upper surface of the second support rod, and the upper surface of the support plate is used for abutting against the lower surfaces of the first frame and the second frame.

[0045] The implementation principle of an aggregate storage device according to an embodiment of the present application is as follows: The first conveying section 11 and the second conveying section 12 in the conveying mechanism 1 are connected by a hinge assembly 4, so that the conveying mechanism 1 is a foldable structure, which can make the overall aggregate storage device relatively reduce in volume when moving, facilitating movement. The first conveying section 11 of the conveyor belt 16 is used to form part of the aggregate hopper, and the material output of the aggregate hopper is controlled by starting and stopping the conveyor belt 16. The length space in the conveying direction of the conveyor belt 16 is fully utilized, the storage capacity of the hopper is increased, and the stored aggregate can be spread out in the length direction of the conveyor belt 16. The conveyor belt 16 is evenly stressed, the transmission load is reduced, the concentration degree of the aggregate in the storage space is also reduced, and the stress on the aggregate bin 2 is reduced, improving the structural stability of the aggregate bin 2. At the same time, due to the conveying power of the conveyor belt 16, the aggregate in the aggregate bin 2 can be kept in an inclined movement state. The aggregate has a tendency to move upward obliquely in the aggregate bin 2 and then slide downward due to gravity. The combination of multiple movement states reduces the compaction phenomenon caused by the long-term static accumulation of the aggregate, facilitating the output of the aggregate.
