Description

Technical Field

[0001] This utility model relates to the field of material crushing equipment technology, specifically a multi-functional crusher with switchable crushing modes. Background Technology

[0002] In fields such as ore processing and building material preparation, crushing devices are key equipment for material pretreatment. Traditional crushing devices mostly use fixed-structure crushing rollers, which have the following problems: First, the roller teeth wear down after prolonged use. Since the roller teeth are integrated with the crushing roller or are difficult to disassemble, replacing the roller teeth requires disassembling the entire crushing roller, which is complex and time-consuming, seriously affecting production efficiency. Second, the spacing between the crushing rollers is usually a fixed value, which cannot be flexibly adjusted according to the characteristics of different materials and crushing requirements, resulting in uneven particle size and difficulty in meeting diverse production requirements. Third, maintenance of the crushing chamber is inconvenient. When it is necessary to clean the residual material in the crushing chamber or repair internal components, the enclosed structure of the chamber restricts the operating space for workers, increasing maintenance difficulty and safety hazards. In addition, during the material conveying process, traditional crushing devices are prone to spillage from equipment gaps, causing material waste and pollution of the working environment.

[0003] Therefore, those skilled in the art have provided a multi-functional crusher with switchable crushing modes to solve the problems mentioned in the background art. Utility Model Content

Example

[0026] Reference Figures 1-6This embodiment is based on the previous embodiment, but differs in that the adjusting assembly is provided with a left moving seat 15 and a right moving seat 20, respectively. A left column 14 and a right column 21 are fixedly connected to the left moving seat 15 and the right moving seat 20, respectively.

Support legs 8 are fixedly connected to the lower end of the crushing chamber 1 near the four corners.

[0029] Working Principle: When using this crushing device, firstly, based on the characteristics of the material to be crushed and the target particle size, if it is necessary to adjust the distance between the crushing rollers, start drive motor 17. It drives screw 18 to rotate via a coupling, causing the left and right moving seats 20, which are threaded to screw 18 and slidably engaged with guide rod 19, to move synchronously. This drives crushing roller 4 to move to the right, achieving precise adjustment of the distance between the two rollers. After adjustment, start drive motors 5 and 2, which drive crushing rollers 3 to rotate in opposite directions (left and right) via couplings and reducers, respectively. Material flows from crushing chamber 1... The material is fed into the crusher and crushed under the squeezing and shearing action of the two rotating crushing rollers. The finished product is discharged from the lower discharge hopper 7. When the roller teeth 23 are worn and need to be replaced, loosen the bolts of the movable side plate 2 and flip it downward to expose the inside of the crushing chamber 1. Unscrew the bolts inside the roller teeth 23, pull out the old roller teeth 23, insert the new roller teeth 23 and fix them. Then reset the movable side plate 2. During the entire crushing operation, the baffle plate 12 on the right 4 rotating shaft 13 of the crushing roller is always in close contact with the inner wall of the crushing chamber 1, continuously preventing the material from overflowing from the through hole 11, ensuring that the crushing operation is stable and efficient.
