Description

Technical Field

[0001] The utility model relates to the technical field of concrete batching machines, in particular to a measuring bucket of a concrete batching machine. Background Art

[0002] At present, the existing concrete batching machine metering hopper is open. Figure 2 As shown, a powder bin, an aggregate bin and an open measuring hopper are arranged above the mixer hopper. During metering, the aggregate bin first adds aggregates into the open measuring hopper, and after completion, the powder bin adds powders into the open measuring hopper. When the batching machine batches the powders, such as cement, fly ash, etc., the powders are beaten into the open measuring hopper, which will cause dust to fly all over the sky and pollute the environment. In addition, the powders are directly piled on the aggregates, such as gravel, sand, etc., and the aggregates are usually wet. The powders are easy to clump when they meet the aggregates and adhere to the inner wall of the measuring hopper, resulting in unclean unloading, which requires frequent manual cleaning and affects the use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a concrete batching machine measuring bucket in view of the deficiencies of the above-mentioned prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A measuring hopper of a concrete batching machine comprises two silos, one of which is an open silo and the other is a sealed silo. The measuring hopper composed of the open silo and the sealed silo is installed on a frame of the concrete batching machine.

[0006] Furthermore, an aggregate bin is arranged above the frame of the concrete batching machine, and the aggregate bin is located above the open bin body. A powder bin is arranged on the side of the frame of the concrete batching machine, and the powder bin is connected to the sealed bin body of the metering hopper through a conveying device.

[0007] Furthermore, an upper sealing plate is arranged above the sealed warehouse body to close the upper opening of the sealed warehouse body, and a feed interface and a vent pipe are arranged on the upper sealing plate, and the vent pipe extends into the open warehouse body.

[0008] Furthermore, the conveying device adopts a screw conveyor, which includes a feed interface and a discharge interface. The feed interface of the screw conveyor is connected to the discharge port of the powder silo, and the discharge interface of the screw conveyor is connected to the feed interface of the sealed silo body through a hose.

[0009] Furthermore, a meter is installed on the side of the sealed warehouse body.

[0016] The technical solutions in the embodiments of the present utility model will be described clearly and completely below. Example

[0017] like Figure 1 As shown, a concrete batching machine metering hopper includes two silos, one of the two silos is an open silo 1, and the other silo is a sealed silo 2. The metering hopper composed of the open silo 1 and the sealed silo 2 is installed on the frame of the concrete batching machine, and the sealed silo 2 is arranged on the side of the open silo 1, wherein an aggregate silo 3 is arranged above the frame of the concrete batching machine, and the aggregate silo stores aggregates such as gravel, sand, etc. The aggregate silo 3 is located above the open silo 1, and a powder silo 4 is arranged on the side of the frame of the concrete batching machine, and the powder silo stores powders such as cement, fly ash, etc. The powder silo 4 is connected to the sealed silo 2 of the metering hopper through a conveying device 5.

[0018] In this embodiment, an upper sealing plate is provided above the sealed silo 2 to seal the upper opening of the sealed silo 2, and an air vent 6 is provided on the upper sealing plate, and the air vent 6 extends into the open silo 1. The conveying device 5 adopts a screw conveyor, and the screw conveyor includes a feed interface and a discharge interface. The feed interface is connected to the discharge port of the powder silo 4. The upper sealing plate is provided with a feed interface, and the discharge interface of the screw conveyor is connected to the feed interface of the sealed silo 2 through a hose 7. In the batching process, the aggregate is first proportioned, After the aggregate fills the open silo 1, the lower outlet of the sealed silo 2 and the air vent 6 are buried in the aggregate, and then the powder is proportioned. The screw conveyor 5 drives the powder into the sealed silo 2. Since the sealed silo 2 is used to proportion the powder alone, the powder and the aggregate are separated by dry and wet conditions, which can prevent the powder from getting wet and clumping on the inner wall of the silo, making it easy to clean. The air vent 6 ensures that the internal air pressure of the sealed silo 2 is balanced with the external air pressure. Since the air vent 6 is buried in the aggregate during proportioning, no dust will be generated during the proportioning process.

[0019] A metering device 8 is installed on the side of the sealed silo 2, and weighing is performed by the metering device 8. After weighing, the aggregate and powder are sent into the upper hopper 10 of the mixer by the belt conveyor 9.

[0020] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
