Description

Technical Field

[0001] This utility model relates to the field of loading and unloading transportation, and in particular to a dry powder hopper unloading device. Background Technology

[0002] Dry powder loading and unloading machines are suitable for quantitative packaging and loading / unloading of powdered, granular, and solid materials in industries such as chemicals, food, and agricultural products. They typically employ a screw feeder controlled by a servo motor, offering high precision and speed.

[0003] The dry powder loading and unloading device feeds the material into the hopper, and then uses a auger conveyor and a geared motor to achieve rapid loading, unloading and transportation. The advantages of the dry powder loading and unloading device are significant in many situations. High efficiency: The dry powder device can accurately control the amount of powder added and work continuously and stably, improving the addition efficiency.

[0004] If the material is fed too quickly or unevenly from the top of the hopper, it can easily cause blockages. During conveyor operation, large amounts of dust often overflow at transfer points and the feed inlet, causing serious environmental pollution. Compared to liquid dosing devices, dry powder loading and unloading devices have lower maintenance costs, longer equipment lifespan, and reduced replacement frequency. Since dry powder can be used directly, it avoids the energy loss and waste generated by powder-based solutions. The high degree of automation, with its automated control system, makes the loading and unloading process simpler and more efficient, reducing the possibility of manual intervention.

A feeding hopper 1 is fixedly connected to the top of the inlet 14, with a large opening for easy material input. A reciprocating mechanism support frame 15 is fixedly connected inside the feeding hopper 1 to reinforce and stabilize the reciprocating mechanism. Two gear 17 fixing bases 18 are fixedly connected to the top of the reciprocating mechanism support frame 15, providing good stability for the gear 17 fixing bases. A pulley 22 is rotatably connected to the inner side of the gear 17 fixing base 18, and a belt is sleeved between the two pulleys 22. The belt 21 allows the pulley 22 to operate flexibly. The pulley 22 is fixedly connected to the gear 17 on the side away from the fixed base 18 of the gear 17. A reciprocating rod 20 meshes between the two gears 17. A resistance rod 19 is fixedly connected to the outside of the reciprocating rod 20. A motor 16 is fixedly connected to the top of the reciprocating mechanism support frame 15, which can provide stable power output for the reciprocating mechanism. The output end of the motor 16 is fixedly connected to the inside of the gear 17. The bottom of the auger conveyor 10 is fixedly connected to the auger conveyor base 12. The bottom of the auger conveyor base 12 is fixedly connected to the support frame 4, which can ensure good stability and load-bearing capacity during the operation of the entire device.

[0036] Reference Figure 1 and Figure 3 The top of the auger conveyor 10 is fixedly connected to a vacuum pump bracket 9, and the left side of the vacuum pump bracket 9 is fixedly connected to a vacuum pump 8, which provides suction to the pipeline. The input end of the vacuum pump 8 is fixedly connected to an air pipe 3, and the left side of the air pipe 3 is fixedly connected to a filter 6, which can effectively filter dust in the intake air. The top of the filter 6 is fixedly connected to an air pipe 5, and the top of the air pipe 5 is fixedly connected to a suction ring 13, which can evenly adsorb the dust generated during the conveying process. The top of the auger conveyor 10 is fixedly connected to a valve switch 7, which facilitates cleaning the dust in the filter 6.

[0037] Reference Figures 1-3 The bottom of the auger conveyor 10 is fixedly connected to the discharge port 11, which makes unloading more convenient.

[0038] Reference Figure 1 The top of the support frame 4 is fixedly connected to the feeding hopper support column 2, which provides stability for the support column. The feeding hopper 1 is fixedly connected to the inside of the support frame 4 to stabilize and reinforce the feeding hopper 1.

[0039] Reference Figure 2 , Figure 4 and Figure 5 The bottom of the reciprocating mechanism support frame 15 is fixedly connected to a reciprocating rod bracket 23, which is slidably connected to the outside of the reciprocating rod 20 to maintain the stable vertical operation of the reciprocating rod 20.

The bottom end of the reciprocating rod 20 is set inside the feed inlet 14, which can promote the flow of materials.

[0042] Working Principle: Material is fed into the feeding hopper 1. The motor 16 is started, and the connection between the pulley 22 and the belt 21 causes two gears 17 to rotate in the same direction. The rotation of gears 17 drives the reciprocating rod 20 to move downwards and then upwards, performing continuous reciprocating motion. Under the constraint of the reciprocating rod support frame 23, it moves smoothly up and down. Simultaneously, it drives the bottom resistance rod 19 to move inside the feed inlet 14, clearing and dispersing the material to facilitate its entry into the auger conveyor 10 and prevent blockage. When the vacuum pump 8 is running, it provides suction to the air pipe 3, which in turn provides suction to the filter 6. The filter 6 provides suction to the air pipe 5, which in turn provides suction to the suction ring 13. The suction ring 13 evenly absorbs the dust generated during transport. The dust passes through the suction ring 13 to the air pipe 5, reaches the filter 6 for filtration, and finally exits through the air pipe 3 to the vacuum pump 8. Finally, the valve switch 7 is opened to allow the powder to be discharged into the auger conveyor, preventing waste.
