The invention discloses machining drilling equipment capable of replacing multi-model drill bits, and relates to the technical field of drilling. The device comprises a device body, supporting legs are arranged at the bottom of the device body, an L-shaped plate is arranged at the edge of the top of the device body, a workbench is arranged at the center of the top of the device body, the device further comprises an anti-jamming device, the anti-jamming device is arranged at the top of the inner wall of the L-shaped plate, and the anti-jamming device comprises a drilling assembly, an electric telescopic rotating column, a telescopic clamping ring and a drilling head. The top of the drilling assembly is fixedly installed on the top of the inner wall of the L-shaped plate, the top of the electric telescopic rotary column is rotationally installed in the center of the bottom of the drilling assembly, and a spring is arranged on the outer wall surface of the telescopic end of the electric telescopic rotary column. By means of the telescopic clamping ring, the telescopic clamping ring is made to adapt to drilling heads of different sizes and diameters by means of the contraction characteristic of the telescopic clamping ring and the abutting force generated when the drilling heads are installed, the method is different from the complexity of manual accessory replacement of transmission workers, and the working efficiency is improved to a certain degree.

The utility model relates to the technical field of waste gas treatment of fuming cupboards, and discloses a waste gas treatment device for a fuming cupboard, which comprises a fixed frame, a filter box body is fixedly connected to the fixed frame, and a top cover is arranged at an opening in the top of the filter box body. Dust collected in a dust collecting box is poured out and cleaned, dust on a filter bag can be effectively and conveniently collected, a high-pressure air injection device is started and releases compressed air into a supporting framework through a partition plate, the compressed air impacts on the inner surface of the filter bag, and dust on the inner surface of the filter bag is removed. When the air passes through the filter bag, stubborn dust which is not shaken off on the surface of the filter bag is blown off, the dust on the filter bag can be effectively cleaned in time through operation of the mechanisms, and the problem that the air purification efficiency is low due to the fact that the filter bag is blocked by the attached dust is solved.

The present invention discloses a mechanical processing drilling device with multiple types of drill bits to be replaced, and relates to the technical field of drilling. The present invention includes a device body, a support leg is arranged at the bottom of the device body, an L-shaped plate is arranged at the top edge of the device body, a workbench is arranged at the top center of the device body, and an anti-stuck device is also included, the anti-stuck device is arranged at the top of the inner wall of the L-shaped plate, the anti-stuck device includes a drilling assembly, an electric telescopic rotating column, a telescopic clamping ring and a drilling head, the top of the drilling assembly is fixedly installed on the top of the inner wall of the L-shaped plate, the top of the electric telescopic rotating column is rotatably installed at the bottom center of the drilling assembly, and a spring is arranged on the outer wall surface of the telescopic end of the electric telescopic rotating column. The present invention enables the telescopic clamping ring to adapt to drilling heads of different sizes and diameters by relying on its own contraction characteristics and the resistance force generated when the drilling head is installed, which is different from the complexity of manual replacement of accessories by transmission staff, and improves work efficiency to a certain extent.
