Description

Technical Field

[0001] The utility model relates to the technical field of raw material transportation, in particular to a material feeding metering structure for mineral raw material transportation. Background Art

[0002] Mineral raw materials refer to mineral aggregates mined from ore deposits for the extraction of useful components or which themselves have certain properties that can be utilized. There are many types of mineral raw materials. When mining and refining mineral raw materials, it is necessary to select appropriate mining methods and refining technologies based on factors such as ore type, ore deposit type, geological conditions and economic properties.

[0003] Mineral raw materials are generally transported by conveyor belts, but traditional mineral raw material transportation only uses a hopper to simply unload the materials onto a conveyor belt for transportation. In subsequent production, the raw materials need to be measured and proportioned, and the production efficiency is extremely low. Therefore, a material unloading and metering structure for mineral raw material transportation is needed. Utility Model Content

[0004] The utility model discloses a material discharging and metering structure for conveying mineral raw materials, aiming to solve the technical problem that the mineral raw materials are simply discharged onto a conveyor belt by a hopper for conveying, and the raw materials need to be metered and proportioned in subsequent production, resulting in extremely low production efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A material feeding and metering structure for conveying mineral raw materials, comprising a frame and a conveying device, and also comprising:

[0007] A mixing mechanism, used for mixing raw materials;

[0008] Opening and closing mechanism for material storage and unloading;

[0009] The top outer wall of the frame is equipped with a first hopper and a second hopper, the bottom outer wall of the first hopper is provided with a mounting cylinder, the top outer wall of the first hopper is equipped with a first motor, the output end of the first motor is connected to a first screw rod, the bottom end of the second hopper is connected to a conveying pipe, a second motor is equipped with a side outer wall of the conveying pipe, and the output end of the second motor is connected to a second screw rod;

[0010] The opening and closing mechanism includes two bottom plates connected to the bottom outer wall of the mounting tube by hinges, the outer walls on both sides of the bottom plates are connected to connecting rods through rotating shafts, the outer walls on both sides of the mounting tube are installed with mounting blocks, the bottom outer wall of the mounting block is installed with an electric telescopic rod, and the piston end of the electric telescopic rod is connected to a connecting block.

[0011] In this solution, the cylinder is installed by closing the bottom plate, and the raw materials are quantitatively discharged through the first screw rod and the second screw rod. Finally, the bottom plate is opened to allow the proportioned raw materials to fall onto the conveying device for orderly transportation. During the process of discharging and conveying, metering and proportioning are carried out at the same time, which can improve production efficiency compared with traditional raw material transportation.

[0012] In a preferred embodiment, the mixing mechanism comprises a rotating rod connected to the bottom end of the first spiral rod, and the outer wall of the rotating rod is connected to a stirring blade.

[0013] In order to further improve production efficiency, a rotating rod and a stirring blade are added at the bottom of the first screw rod. When the raw materials fall into the installation cylinder, the stirring blade rotates with the first screw rod to stir and mix the raw materials, which can omit the subsequent stirring process and further improve production efficiency.

[0014] As can be seen from the above, a material metering structure for conveying mineral raw materials includes a frame and a conveying device, and also includes:

[0015] A mixing mechanism, used for mixing raw materials;

[0025] The utility model discloses a material unloading and metering structure for conveying mineral raw materials, which is mainly used in the scenario where traditional mineral raw material conveying only utilizes a hopper to simply unload the materials onto a conveyor belt for conveying, and in subsequent production, the raw materials need to be metered and proportioned, resulting in extremely low production efficiency.
