Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a heavy-duty automatic adjustable through crusher. Background Technology

[0002] In the coal industry, in order to meet the needs of the downstream market, mines will choose a variety of different finished product particle sizes. Currently, most through-type crushers on the market require workers to manually adjust the output particle size of the equipment by using bolts or shims after the machine is stopped. This is time-consuming, labor-intensive, and the downtime for adjustment leads to production interruption. It is impossible to adjust according to changes in materials (such as hardness and particle size). It is easy to jam or be damaged when encountering hard objects. When the crushing gap is not suitable, it is easy to cause excessive wear of the hammers or even blockage. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the extension and retraction of the hydraulic telescopic column can drive the upper and lower sliding seats to slide up and down along the U-shaped groove. The upper and lower sliding seats can drive the crushing roller to move up and down, thereby adjusting the gap between the crushing roller and the straight section guide chute, thus adjusting the crushing gap. When the crushing roller moves upward, it drives the lower end of the protective support shell to move upward. The protective support shell drives the crushing motor to rotate, and the crushing motor drives the rotating support to rotate. The protective support shell ensures that the belt and pulley between the crushing roller and the crushing motor are always in a taut state. When the rotating support rotates, it can drive the sliding block to slide along the sliding rod, thereby ensuring smoother rotation of the rotating support and making control more convenient. This heavy-duty automatic crushing gap adjusting through-type crusher has a simple structure and is easy to operate. The crushing gap can be precisely adjusted through hydraulic control, thereby reducing the labor intensity of workers and reducing downtime. Attached Figure Description

A hydraulic telescopic column 14 is mounted on the hydraulic push rod base 15. The telescopic end of the hydraulic telescopic column 14 is fixed to the lower surface of the upper and lower sliding seats 8. The extension and retraction of the hydraulic telescopic column 14 drives the upper and lower sliding seats 8 along the U-shaped groove. 3. The crushing roller 9 can be moved up and down by the sliding seat 8, thereby adjusting the gap between the crushing roller 9 and the straight guide chute 7, and thus adjusting the crushing gap. The crushing drive device includes a support installed between the scraper conveyor 1 and the U-shaped chute 3. Two lower mounting bases 13 are installed on the front and rear sides of the upper surface of the support. The upper surface of each of the two lower mounting bases 13 is connected to a rotating support 12 by a hinge. A sliding connector 5 is provided between the other end of the rotating support 12 and the upper surface of the lower mounting base 13. A crushing motor 11 is fixed on the upper surface of each of the two rotating supports 12. The two crushing motors 11 are controlled simultaneously, and the control method is existing technology. For example, installing an NPS102 controller can control the simultaneous operation of two crushing motors 11. The output shaft end of the crushing motor 11 is connected to the end of the crushing roller 9 via a belt and pulley. A protective support shell 4 is provided between the output shaft of the crushing roller 9 and the output shaft of the crushing motor 11. The output shaft of the crushing roller 9 and the crushing motor 11 are connected to the protective support shell 4 via bearings.

This heavy-duty automatic adjustable crusher has a simple structure and is easy to operate. The crushing gap can be precisely adjusted by hydraulic control, thereby reducing the labor intensity of workers and reducing downtime. In use: The extension and retraction of the hydraulic telescopic column 14 causes the upper and lower sliding seats 8 to slide up and down along the U-shaped groove 3. The upper and lower sliding seats 8 can drive the crushing roller 9 to move up and down, thereby adjusting the gap between the crushing roller 9 and the straight guide chute 7, thus adjusting the crushing gap. When the crushing roller 9 moves upward, it drives the lower end of the protective support shell 4 to move upward. The protective support shell 4 drives the crushing motor 11 to rotate, and the crushing motor 11 drives the rotating support 12 to rotate. The protective support shell 4 ensures that the belt and pulley between the crushing roller 9 and the crushing motor 11 are always in a taut state. When the rotating support 12 rotates, it can drive the sliding block 53 to slide along the sliding rod 52, thereby ensuring that the rotating support 12 rotates more smoothly and making control more convenient. This allows for adjustment of the crushing gap. When the raw material flows down through the straight section guide chute 7, it passes through the crushing roller 9. The rotation of the crushing motor 11 can drive the crushing roller 9 to rotate, and the crushing roller 9 can crush the raw material. After crushing, the raw material falls onto the upper surface of the scraper conveyor 1. The scraper conveyor 1 can transport the crushed raw material to the roller screen 2, and the roller screen 2 can screen the crushed raw material to complete the processing.
