Furthermore, it should be understood that in some electric skip cars 10 preset with an automatic control program, the control panel may be omitted, which does not affect the realisation of the above work and the achievement of technical purposes.

In this embodiment, as shown in fig. 1, in order to prevent the damage to the environment caused by the powder lifting during the bag breaking and discharging of the incoming material breaking assembly 1 and the direct loss caused by the loss of the lifted and scattered powder, the incoming material breaking assembly 1 is connected with a first filtering and dust collecting assembly 14, the first filtering and dust collecting assembly 14 comprises a fan for generating negative pressure suction, and the fan creates a negative pressure environment, so that the powder is sucked into the assembly from the lifted material generated by the material breaking assembly 1, and the first filtering and dust collecting assembly 14 further comprises a cloth bag for realizing the functions of filtering and dust collecting.

In the embodiment, the material sucking and metering assembly 4 comprises a main frame 16, wherein a metering bin 17 connected with the incoming material breaking assembly 1 and a collecting bin 18 connected with the metering bin 17 are respectively arranged in the main frame 16 from top to bottom, the metering bin 17 and the collecting bin 18 are in connection and fit through flexible hoses, and a first electric control valve 19 is arranged at the connection position; the measuring bin 17 is internally provided with an inductor 2 for inducing the height of dust, and the powder measurement and calculation are realized by matching the height data with the shape and the volume of the measuring bin; the metering bin 17 is connected with the negative pressure equipment 5 through a pipeline, and the negative pressure equipment 5 provides a negative pressure environment for the metering bin 17, so that the metering bin 17 can suck the powder particles in the incoming material breaking component 1.

In this embodiment, the aggregate bin 18 is provided with a plurality of discharge ports, and each discharge port is provided with an electric control valve, and the electric control valve can control the opening and closing of the discharge port to realize discharge.

It should be understood that even if the measuring bin 17 is designed to be completely sealed, dust will be generated inevitably when powder is sucked, in order to solve the dust generated in the measuring bin and process the dust, the second filter dust collection assembly 20 is installed in the measuring bin 17 to collect the dust, and after a certain amount is collected, the dust is sent out.

It will be appreciated that the second filter cleaning assembly 20 is provided with a filter arrangement which is effective to capture and filter dust generated from the metering hopper 17. The filter device typically includes a filter, cartridge or other filter media having a fine pore structure that is effective in capturing dust particles. The filtered dust is collected and stored in the second filter dust collection assembly 20. Dust can be stored centrally within the assembly in the form of a collection container or dust bag, or the like. When a certain amount of dust has accumulated, it can be treated or cleaned periodically to ensure proper operation of the assembly and effective dust treatment. Once the second filter and dust collection assembly 20 has collected a quantity of dust, it can be disposed of by a suitable disposal method. This may include transferring the dust to specialized processing equipment, collection containers, or for subsequent processing, such as recycling, reuse, or safe disposal.

By introducing the second filter dust collection assembly 20, efficient collection and disposal of dust generated within the metering bin 17 can be achieved. This helps to reduce the impact of dust on the environment and operators and ensures the safety and hygiene of the metering process. Meanwhile, accumulated dust in the second filter dust collection assembly 20 is treated and cleaned periodically, so that the filtering efficiency and the operation efficiency can be maintained, and the reliability and the persistence of the device are ensured.

In this embodiment, in order to prevent the blockage of the discharge, the above problem is solved by vibrating during the discharge process, so that a vibration anti-blocking assembly is introduced into the device, the vibration anti-blocking assembly has two vibration units, the first vibration unit 21 is mounted on the metering bin 17, the metering bin 17 is driven to vibrate by vibration, the adhesive force between the powder and the inner wall surface of the metering bin 17 can be broken by the vibration, the powder is kept in a loose state, and thus the smooth discharge process is promoted, and the attachment on the inner wall surface of the metering bin 17 during the discharge of the powder is prevented. The second vibration unit 22 is installed in the aggregate bin 18, and drives the aggregate bin 18 to vibrate through vibration, so that powder can be prevented from adhering to the inner wall surface of the aggregate bin 18 through vibration, free flow of the powder during discharging is ensured, and blockage is avoided or discharging resistance is reduced. By introducing the vibration anti-blocking component, the problems of adhesion and blockage possibly generated in the discharging process of the powder can be effectively solved. The first vibration unit 21 and the second vibration unit 22 function to break the adhesion between the powder and the inner wall surface of the bin by the vibration force so that the powder maintains fluidity and smoothly flows out from the bin.

It should be noted that the intensity and frequency of the vibration should be adjusted and controlled according to the nature and discharge requirements of the powder to ensure that the blocking problem is solved without adversely affecting the structure and stability of the device. In addition, as a cooperation of the vibration anti-blocking assembly, rubber blocks are arranged on the installation positions between the metering bin 17 and the collecting bin 18 and the main frame 16, and the rubber blocks play a role of flexible connection, so that the influence of the rigid structure of the main frame 16 on the occurrence and effect of vibration is avoided. This flexible connection effectively isolates the rigid nature of the main frame so that the vibration anti-blocking assembly can function better. The vibration and choke assembly is typically required to generate a specific vibration pattern to prevent material from clogging in the metering and collecting bins 17, 18. By using rubber blocks for flexible connection, it is ensured that vibration can be efficiently transferred to the metering bin 17 and the collecting bin 18 without being affected by the rigid structure of the main frame 16. Therefore, the vibration anti-blocking assembly can be ensured to work normally, and blockage and accumulation of materials are prevented.
