Description

Technical Field

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

[0002] Batching machine, also known as aggregate batching machine, concrete batching machine, is used to store and measure various sand and gravel aggregates in concrete or asphalt mixing plants, and transport them to the mixer according to the pre-set formula, and mix them with cement, fly ash, mineral powder, additives, water, etc. to form concrete. The concrete machinery transports gravel, sand, block stones and other raw materials, and transports the raw materials to the main machine through the belt scale. The batching machine sets the concrete mix ratio, and automatically batches the ingredients according to the set mix ratio to mix into concrete.

A discharge pipe 55 is fixedly connected to the wall of the batching bin 2 on one side away from the dust shield 4 and close to the bottom. One end of the discharge pipe 55 is located in the inner cavity of the batching bin 2, and the other end of the discharge pipe 55 is fixedly connected to the bottom of the lower hopper 54. A vibration motor 56 is fixedly connected to the discharge pipe 55. The vibration motor 56 can prevent dust from accumulating in the inner cavity of the discharge pipe 55 and causing blockage.

[0024] A dust reduction assembly 6 is provided on the discharge bin 3 and near the bottom, and the dust reduction assembly 6 includes a water storage tank 61 fixedly connected to the side wall of the discharge bin 3, a connecting pipe 63 is fixedly connected to the bottom of the water storage tank 61, a control valve 62 is fixedly installed at the water inlet end of the connecting pipe 63, a "mouth"-shaped guide pipe 64 is fixedly connected to the bottom of the connecting pipe 63, the opposite side wall of the guide pipe 64 is fixedly connected to the side wall of the discharge bin 3, and a plurality of atomizing nozzles 65 are fixedly connected to the outer wall of the guide pipe 64.

[0025] The working principle of this utility model:

[0026] When in use, first open one side of the dust shield 4 on the batching bin 2, and put the ingredients into the inner cavity of the batching bin 2. When each ingredient enters the inner cavity of the batching bin 2, the powder will float out from the upper port of the batching bin 2 due to its light weight. Then, cover the dust shield 4 to prevent some dust from floating in the air. At the same time, start the induced draft fan 57. Under the action of the suction force of the induced draft fan 57, the dust is collected into the inner cavity of the dust collecting box 53 through the dust collecting pipe 52, and then falls from the dust collecting box 53 to the lower hopper 54. In the inner cavity, the powder returns to the inner cavity of the batching bin 2 through the discharge pipe 55 by the cooperation of the discharge pipe 55 and the vibration motor 56. Not only will it not float in the air, but the floating powder can be recovered into the batching bin again, and waste is also avoided. When discharging, the control valve 62 is started. At this time, the water in the water tank 61 flows into the inner cavity of the guide pipe 64 through the connecting pipe 63. The water is collected in the inner cavity of the guide pipe 64 and then sprayed out by the atomizing nozzle 65 to reduce dust on the powder falling from the outlet of the discharge bin 3.
