The invention discloses a jaw crusher with functions of spray dust suppression and dust collection dust removal, the jaw crusher comprises a jaw crusher body, the front side and the rear side of the left side of the top of the jaw crusher body both are fixedly connected with a first fixing plate. The jaw crusher body, a first nozzle, a second nozzle, a first dust collector, a telescopic tube, a first dust collection cover, an adjusting mechanism, a third nozzle, a second dust collector, a connecting tube, a second dust collection cover, a clamping block, a filter plate, an opening, a baffle plate, a fixing mechanism, a through opening, a storage box, a box door, a fixing column, a fixing block, a pull ring, a clamping rod and a clamping groove are matched for use, so that the problem the most existing jaw crushers do not have the function of inhibiting dust generation is solved. In the process of working, dust may inevitably be generated at a feeding port, a discharging port and a crushing cavity, and especially when in crushing of materials such as limestone, a large amount of dust will be generated, and not only pollutes the environment, but also damages the health of workers.
