Description

Technical Field

[0001] The utility model relates to the technical field of hopper equipment, in particular to an impact-resistant drop hopper for a stacker-reclaimer. Background Art

[0002] A stacker-reclaimer is a device that has both stacking and reclaiming functions during the process of ore storage and transportation and ore homogenization. It can continuously transport ore to the material yard to pile it into a pile, and can also continuously take out ore from the pile in the material yard. The stacker-reclaimer is a special equipment in the bulk material storage yard. The impact-resistant drop hopper is a key component specially designed for stackers and reclaimers. Its main function is to withstand the huge impact force generated when the material falls, and to ensure that the material can enter the next processing link stably and smoothly. There are many types of weighing hoppers on the market with different models, but there is a general problem of insufficient impact resistance. When continuous material enters, the weighing hopper will be impacted by the material, causing a resonance effect, resulting in damage to the hopper, which greatly shortens the service life of the weighing hopper.

[0003] In order to solve the above problems, the utility model patent with publication number CN214932668U discloses an impact-resistant weighing hopper, which can avoid the resonance phenomenon caused by material impact by dispersing the impact force. Compared with the existing vertical drop weighing hopper, it has better impact resistance and longer service life, and can reduce production costs.

[0004] There are still some shortcomings in the use of the above-mentioned impact-resistant drop hopper. The drop angle and drop port height of the drop hopper are usually fixed structures, which makes it inconvenient to flexibly adjust the drop hopper according to the required angle and height when dropping materials. Due to the differences in particle size and density of different materials, it is not convenient to adapt to the characteristics of different materials, it is not convenient to drop materials, and it is not convenient to control the distribution and falling position of materials, which is not conducive to the uniform distribution of materials when dropping materials, reducing the flexibility and adaptability of the drop hopper.
