Description

Jaw crusher adjusting device Technical Field The application relates to the field of jaw crushers, in particular to a jaw crusher adjusting device. Background The jaw crusher is commonly called jaw crusher and mainly comprises a frame, fixed jaw plates, movable jaw plates, upper and lower guard plates, an eccentric shaft, an adjusting seat, movable jaw pull rods and the like, wherein when the jaw crusher works, the eccentric shaft is driven to rotate by a driving mechanism, the eccentric shaft drives the movable jaw plates to periodically reciprocate on the fixed jaw plates, the jaw crusher is close to the fixed jaw plates and is separated from the fixed jaw plates, when the jaw crusher is close to the fixed jaw plates, materials are extruded, split and impacted between the two jaw plates to be crushed, and when the jaw crusher is separated from the fixed jaw plates, the crushed materials are discharged from a discharge port under the action of gravity. At present, when facing the crushing demands of different sizes of ores, workers usually need to stop the jaw crusher, then adjust the angle of the movable jaw plate, and then adjust the distance between the fixed jaw plate and the movable jaw plate, so that the size of a discharge hole formed by the fixed jaw plate and the movable jaw plate meets the crushing demands of different sizes of ores. But move the angle of adjustment of jaw board limited, and decide the jaw board again and fix in the frame, be difficult to adjust the inclination who decides the jaw board, lead to deciding the jaw board and move the adjustment range of the size of the discharge gate that the jaw board formed less, and then lead to the jaw breaker to the broken size demand of ore when having a big difference the suitability lower. Disclosure of Invention In order to improve the applicability of the jaw crusher when the crushing size requirements of ores are greatly different, the application provides an adjusting device of the jaw crusher. The application provides a jaw crusher adjusting device which adopts the following technical scheme: The jaw crusher adjusting device comprises a movable jaw adjusting mechanism and a fixed jaw adjusting mechanism, wherein the movable jaw adjusting mechanism is arranged on a jaw crusher and used for driving movable jaw plates of the jaw crusher to rotate, the fixed jaw adjusting mechanism is arranged on the jaw crusher and used for driving fixed jaw plates hinged to the jaw crusher to rotate, the fixed jaw adjusting mechanism comprises a supporting rod, a driving piece and a locking assembly, the supporting rod is slidably arranged on a frame of the jaw crusher in a penetrating mode, the supporting rod is abutted to the fixed jaw plates of the jaw crusher, the driving piece is arranged on the frame and used for driving the supporting rod to slide on the frame, and the locking assembly is arranged on the supporting rod and used for positioning the supporting rod on the frame. Through adopting above-mentioned technical scheme, the staff drives jaw breaker's movable jaw board through movable jaw guiding mechanism and rotates for movable jaw board is close to or keeps away from fixed jaw board, and the staff can drive the bracing piece through the driving piece again and slide in jaw breaker's frame simultaneously, makes the bracing piece to be close to or keep away from the direction removal of fixed jaw board, and fixed jaw board can rotate along with the removal of bracing piece to being close to or keep away from the direction of movable jaw board, adjusts the inclination who decides jaw board, can adjust the distance between fixed jaw board and the movable jaw board again, effectively promotes the suitability when the jaw breaker differs great to the crushing size demand of ore. Optionally, the locking subassembly includes locking seat, locking ring, locking piece and setting element, the locking seat sets up in the frame, the locking hole has been seted up on the locking seat, the bracing piece slides and wears to establish on the lateral wall of locking hole, the opening size of locking hole reduces gradually from being close to the direction of deciding the jaw board to keeping away from deciding the jaw board, the locking ring slides and sets up on the bracing piece, the locking piece is provided with a plurality of on the locking ring, and is a plurality of the locking piece is used for supporting tightly to the lateral wall of locking hole, the setting element sets up on the locking ring and is used for fixing a position the locking ring on the bracing piece. Through adopting above-mentioned technical scheme, after the staff has adjusted the position of bracing piece, fix a position the locking ring on the bracing piece through the setting element for a plurality of locking pieces butt on the locking ring are to the lateral wall in locking hole, when jaw breaker broken ore, the ore is to deciding the extrusion of jaw board, decides the jaw
