And the working efficiency is further improved, the structure is simple, and meanwhile materials cannot be damaged.

The utility model belongs to the technical field of stone crushing devices, and provides a multi-stage stone crushing and impacting device which comprises a material throwing and impacting device and a conveyor. The material throwing impact device is composed of an impact cylinder, a material throwing device and a discharging hopper, the material throwing device is arranged in an inner cavity of the impact cylinder, and the inner cavity of the impact cylinder is composed of multiple layers of impact cavities; crushing teeth are uniformly distributed on the inner wall of each impact cavity, the crushing teeth of each impact cavity respectively correspond to one specification, the specification of the crushing teeth on the uppermost layer is the largest, and the specification of the crushing teeth on the lowermost layer is the smallest; the material throwing device is composed of a feeding port, a material throwing cylinder and a material throwing motor, a guide plate is arranged in the material throwing cylinder, through grooves are formed in the material throwing cylinder at equal intervals, and broken stones are injected into the material throwing cylinder through the feeding port; according to the scheme, the multi-layer impact crushing device is provided to meet different crushing requirements, the universality of the impact device is improved, the crushing specification can be adjusted by adjusting the relative position of the material throwing barrel and the impact cavity, and the multi-layer impact crushing device is very convenient to use.

The utility model provides a wear -resisting alloy rotary excavating tooth, including connection support body, stable tooth holder, installation connecting groove, installation support base body, broken tooth body and rock breaking tooth tip, wherein: stable tooth holder fixed mounting is in the top of connection support body, and installation connecting groove is opened in the surface of connection support body, and installation support base body fixed mounting is below connection support body, broken tooth body sliding installation is in the outside of installation support base body, and rock breaking tooth tip fixed mounting is in the bottom of broken tooth body, the utility model discloses installation support base body and the setting of broken tooth body, high, can realize efficient progressive crushing, can replace locally after damaging.

The utility model relates to the technical field of mechanical transmission, in particular to a precision gear with an assembly adjustable function, fan-shaped tooth blocks are uniformly mounted between two chucks, T-shaped pins are fixedly mounted on the fan-shaped tooth blocks, T-shaped grooves are formed in the fan-shaped tooth blocks, rotating columns for transmission are mounted on the chucks in a sliding manner, and the T-shaped grooves are formed in the rotating columns. A rotary cover used for clamping the chuck is installed on the rotary column in a threaded mode, and threaded rods used for adjusting the position are evenly and fixedly installed at the side end of the rotary column. When teeth of the fan-shaped tooth block are broken in the transmission process, the screw cap is screwed off, then the chuck at the screw cap end is taken down, the fan-shaped tooth block can be completely exposed outside, then the broken fan-shaped tooth block is pushed along the axis, the broken fan-shaped tooth block can be taken down and replaced with a new fan-shaped tooth block, then the screw cap end is inserted back, and then the screw cap is screwed down. Operation is easy and convenient, broken teeth are convenient to replace, and the maintenance cost is reduced.

The present application belongs to the field of vibration detection, and particularly relates to a kind of conical box component vibration fault detection device, comprising: operation platform;Self-adapting buffer detection mechanism, it is installed inside the operation platform, for with conical box inside gear self-adapting buffer type contact, prevent and gear contact not comprehensive appear detection result inaccuracy phenomenon;Through self-adapting buffer detection mechanism adopts symmetrical arrangement, rack and pinion meshing realizes the reverse synchronous motion of detection head: one side contact tooth top lifts when, the other side automatically probes tooth groove, ensure that detection point all around evenly contact tooth surface.Each detection head independently equipped with spring and damper, form buffer filter system, both can adapt to the microfluctuation of tooth surface, avoid rigid impact, can also filter out high-frequency noise, extract pure vibration signal to identify pitting, broken teeth and other faults.This design fundamentally solves the signal distortion problem caused by poor contact, significantly improves the accuracy, reliability and efficiency of vibration diagnosis.
