Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a reamer metering device which is easy to maintain. Background Art

[0002] Mineral powder is a general term for stone powder and its substitutes that meet engineering requirements. It is the product of ore crushing and processing. It is the first step in ore processing and smelting, and it is also one of the most important steps. The hydrophilicity coefficient of mineral powder is the ratio of the volume of unit mineral powder in the same volume of water (polar molecule) and the same volume of kerosene (non-polar molecule). In highway engineering, mineral powder with a hydrophilicity coefficient of <1 is called alkaline mineral powder.

[0003] In the process of mineral powder production and processing, it is often necessary to weigh and transport the mineral powder. The existing technology generally transports it through a reamer conveyor, and then weighs the material after it falls into the hopper. The operation is relatively cumbersome. For example, the powder weighing device with Chinese patent publication number CN202903300U uses a hoisting frame to hoist the spiral conveying metering reamer. The hoisting frame structure is fixed. When the weight sensor and the reamer need to be maintained, external tools are required for high-altitude maintenance, which is inconvenient to operate and increases the burden on maintenance personnel.

Two mounting brackets are symmetrically fixedly installed on both sides of the upper surface of the top plate 2, and the guide wheels 36 are rotatably connected inside the two mounting brackets, and the guide wheels 36 cooperate with the corresponding steel wire ropes 32. A hopper 6 is fixedly installed through the upper surface of the top plate 2, and a first bag tube 7 is fixedly connected between the bottom end of the hopper 6 and the feed port of the reamer conveyor 43, and a second bag tube 8 is fixedly connected to the discharge port of the reamer conveyor 43.

[0023] When in use, the material falls from the hopper 6 and enters the reamer conveyor 43 through the first bag tube 7. At this time, the weighing sensor 41 can weigh the material. When the reamer conveyor 43 is running, the material can be discharged from the second bag tube 8. The weighing sensor 41 can weigh the weight of the remaining material, ensuring the accuracy of the material conveying amount. When it is necessary to maintain the weighing sensor 41 and the reamer conveyor 43, it is only necessary to open the limit mechanism 5, and then start the two electric hoists 31, and the weighing sensor 41 and the reamer conveyor 43 can be lowered to the ground through the wire rope 32, without the need for tools to climb up for maintenance, so that maintenance is convenient.

[0024] Embodiment 2:

[0025] like Figures 1 to 3 As shown, a limiting mechanism 5 matched with the lifting mechanism 3 is fixedly installed on the lower surface of the top plate 2, and the limiting mechanism 5 includes a U-shaped plate 51 fixedly installed on the lower surface of the top plate 2, and grooves 52 are provided on both sides of the outer surface of the U-shaped plate 51, and a bidirectional screw rod 53 is rotatably connected between the two grooves 52, and both ends of the bidirectional screw rod 53 are threadedly connected with a clamping plate 54 slidably connected to the inner wall of the groove 52, and a clamping groove 55 matched with the clamping plate 54 is provided on the outer surface of the vertical plate 33. A motor 56 is fixedly installed on the lower surface of the U-shaped plate 51, and the output shaft of the motor 56 is fixedly connected to a first bevel gear 57, and the outer surface of the bidirectional screw rod 53 is fixedly sleeved with a second bevel gear 58 meshing with the first bevel gear 57. Both sides of the upper surface of the top plate 2 are provided with openings that are slidably connected to the vertical plates 33. When the electric hoist 31 drives the reamer conveyor 43 to move to the use position, the motor 56 is started, and the motor 56 rotates through the first bevel gear 57 and the second bevel gear 58 to drive the bidirectional screw rod 53 to rotate, and then drives the two clamping plates 54 to move through the threads and clamp them into the clamping grooves 55, so that the vertical plates 33 can be limited, and the electric hoist 31 does not need to be continuously operated, thereby improving the service life.

[0026] Working principle: When in use, the material falls from the hopper 6 and enters the reamer conveyor 43 through the first bag tube 7. At this time, the weighing sensor 41 can weigh the material. When the reamer conveyor 43 is running, the material can be discharged from the second bag tube 8, and the weighing sensor 41 can weigh the weight of the remaining material, thereby ensuring the accuracy of the material conveying amount. When it is necessary to maintain the weighing sensor 41 and the reamer conveyor 43, it is only necessary to open the limit mechanism 5 and then start the two electric hoists 31 to lower the weighing sensor 41 and the reamer conveyor 43 to the ground through the wire rope 32. No tools are needed for maintenance, which makes maintenance easier. When the electric hoist 31 drives the reamer conveyor 43 to move to the use position, the motor 56 is started. The motor 56 rotates through the first bevel gear 57 and the second bevel gear 58 to drive the bidirectional screw rod 53 to rotate, and then drives the two clamping plates 54 to move through the threads and clamp them into the clamping groove 55, so that the vertical plate 33 can be limited, and the electric hoist 31 does not need to run continuously, thereby increasing the service life.

[0027] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
