Description

Technical Field

[0001] The utility model relates to the technical field of waste high-chromium ball processing equipment, in particular to a crushing device for waste high-chromium balls. Background Art

[0002] High chromium balls are usually used to grind ore in ball mills, but they will be damaged or worn out after a period of use and then become scrapped. In order to further recycle and utilize these scrapped high chromium balls, we need to crush them first so that they can be produced again later.

[0003] After high chrome balls are scrapped, the common way to crush them is to manually break them with a hammer or other tools, and then collect the fragments to produce new high chrome balls. However, the manual crushing method is not only time-consuming and labor-intensive, but the splashing of fragments can easily injure the staff.

[0004] Therefore, we have proposed a crushing device for scrapped high-chromium balls that can replace manual and automated crushing and has higher safety. Utility Model Content

A plurality of upper crushing knives are provided, and the upper crushing knives cooperate with the lower crushing knives.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] (1) The utility model is a crushing device for scrapped high-chrome balls. The scrapped high-chrome balls are placed into the processing box through a feed pipe. Due to the inclination of the trapezoidal plate, the high-chrome balls will slide between two inclined limit plates toward the hatch until they can no longer slide, thereby achieving the effect of automatic feeding and automatic limit. At the same time, through the two inclined limit plates, it can also adapt to high-chrome balls of different sizes. When the high-chrome ball stops sliding down, the hydraulic cylinder is driven to drive the crushing mechanism downward. The upper crushing knife cooperates with the lower crushing knife to crush the scrapped high-chrome balls and cause them to break, thereby achieving the function of automatically crushing the high-chrome balls, thereby replacing manual crushing, saving time and effort, and improving the safety of crushing high-chrome balls.

The high-chromium balls entering the processing box 1 will slide toward the hatch 13 between the two inclined limit plates 23 due to the inclination of the trapezoidal plate 2 until they can no longer slide, thereby achieving the effect of automatic loading and automatic limiting. At the same time, the two inclined limit plates 23 can also adapt to high-chromium balls of different sizes. When the high-chromium ball stops sliding down after the limit, the hydraulic cylinder 31 is driven, and the hydraulic cylinder 31 drives the crushing mechanism 3 to press down. The upper crushing knife 32 cooperates with the lower crushing knife 22 to crush the scrapped high-chromium balls and cause them to break, thereby achieving the purpose of automatically crushing the high-chromium balls, thereby increasing the overall practicality.

[0025] Furthermore, the lower end surface of the processing box 1 is fixedly mounted with a support leg 11, the left side of the processing box 1 is provided with a feed pipe 12, and the right side of the processing box 1 is provided with a hatch 13. When in use, during the crushing process of the scrapped high-chrome balls, the broken large pieces of debris will slide along the trapezoidal plate 2 to the hatch 13. When accumulated to a certain extent, the hatch 13 can be opened for processing, thereby increasing the overall applicability. It should be noted that the debris collection effect is only for the collection of large pieces of debris, because small pieces of debris will be limited by the lower crushing knife 22, and small pieces of debris can be collected and processed by other means.

[0026] Furthermore, the mounting groove 21 and the limit plate 23 are set in an inclined state, the lower end of the return spring 211 is fixedly connected to the bottom surface of the mounting groove 21, and the upper end of the return spring 211 is fixedly connected to the lower surface of the limit plate 23. When in use, when the hydraulic cylinder 31 drives the crushing mechanism 3 to press down for crushing, the two sides of the crushing mechanism 3 will also press the limit plate 23, so that the limit plate 23 is retracted into the inside of the mounting groove 21 through the return spring 211 to avoid the limit plate 23 interfering with the downward pressure of the crushing mechanism 3. After the downward pressure is completed, the limit plate 23 loses pressure and rebounds through the return spring 211, thereby limiting the next high chrome ball.

[0027] Furthermore, a plurality of lower crushing knives 22 are provided, and the lower crushing knives 22 are equidistantly arranged along the inclination angle of the limiting plate 23. When in use, by setting the lower crushing knives 22, the upper crushing knives 32 can be cooperated to crush the high chrome balls.

A plurality of upper crushing knives 32 are provided, and the upper crushing knives 32 cooperate with the lower crushing knives 22. When in use, when the high chromium ball is located between the upper crushing knives 32 and the lower crushing knives 22, the upper crushing knives 32 are pressed down and interlaced with the lower crushing knives 22, such as Figure 6 As shown, the high chromium ball can be crushed.

[0029] Working principle: The utility model is a crushing device for scrapped high-chrome balls. When in use, the staff first puts the scrapped high-chrome balls into the processing box 1 through the feed pipe 12. There is an inclined trapezoidal plate 2 at the bottom of the processing box 1. The ball will slide along the trapezoidal plate 2 to the hatch 13. During the sliding process, the ball will stop between the two inclined limit plates 23 according to its own size. The two inclined limit plates 23 can adapt to high-chrome balls of different sizes. After the ball reaches the appropriate position, the hydraulic cylinder 31 is started. The hydraulic cylinder 31 drives the crushing mechanism 3 to press downward, so that the upper crushing knife 32 and the lower crushing knife 22 cooperate with each other to crush the ball. The limit plate 23 can be retracted and popped out by the reset spring 211 to avoid interference with the crushing mechanism 3. The large pieces of broken pieces will slide along the trapezoidal plate 2 to the hatch 13. When they are accumulated to a certain extent, they can be processed, thereby enriching the overall function and increasing the overall applicability.
