The discharge opening adjusting mechanism of the jaw crusher, which is disclosed by the utility model, ensures that the ejector rod is outwards ejected or inwards contracted by the ejector block by driving the wedge-shaped blocks connected with the sleeves to relatively or oppositely move through rotating the screw rods, thereby enabling the discharge opening to be reduced or enlarged in size; and the discharge opening adjusting mechanism of the jaw crusher achieves the convenience, labor conservation and safety during adjustment, and can realize the stepless adjustment of the size of the discharge opening.
Description
Technical field
The utility model relates to a kind of mining machinery, relates to specifically a kind of discharge gate governor motion of jaw crusher.
Background technology
Jaw crusher is a kind of ore crusher that the most generally uses, usually by a frame and place the parts such as power set, fixed jaw and sewing jaw in the frame to form, the wallboard of fixed jaw and sewing jaw and frame two sides consists of a up big and down small wedge shape crusher chamber, drive the swing that sewing jaw is made vertical and horizontal by power set, the ore that places in the crusher chamber is broken and discharges from the discharge gate of crusher chamber bottom.Difference according to the ore of required fragmentation, the size of discharge gate also needs difference, the discharge gate size is mainly regulated by a discharge gate governor motion, as shown in Figure 2, the discharge gate governor motion of existing jaw crusher generally includes a drive link composition that is fixed on the adjuster on the back joint frame and is rotatably connected with adjuster, the other end of drive link is connected with the position of moving jaw near discharge gate, the main polylith backing plate of adjuster and a jacking block form, by increasing or reduce the quantity of backing plate, make drive link drive moving jaw, and then regulate nesting population size and reduce or increase.The adjustment process of existing this discharge gate governor motion all needs to finish at machine intimate, and is both dangerous, also inconvenient, and by the size that the quantity that increases or reduce backing plate is regulated discharge gate, the variation of discharge gate all is stepped after regulating at every turn.
The utility model content
For overcoming defects, the utility model aims to provide a kind of both safety, regulates easily again the discharge gate size, can realize again the discharge gate governor motion of the jaw crusher of discharge gate step-less adjustment simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of discharge gate governor motion of jaw crusher, comprise an adjusting seat and push rod, have an adjuster and a jacking block in the described adjusting seat, two ends of described push rod are rotatably connected with jacking block and the moving jaw position near discharge gate respectively, described adjuster comprises two wedges of relatively installing, the large end of described wedge is connected with a screw rod, described external thread of screw is connected with a sleeve, described sleeve is towards an end of the wedge support that has been rotatably connected, described support and adjusting seat fix, and described sleeve has an adjusting head away from an end of wedge.
Described bush outer sleeve has a locking pipe, and described locking pipe is positioned at and has a locking screw on the adjusting head position, is connected with a stop pin on the described locking screw.The junction of described support and sleeve is provided with bearing.
Adopted the discharge gate governor motion of jaw crusher of the present utility model, by the adjusting head on the turnbarrel drive wedge on the screw rod do relative to or moving in opposite directions, so that wedge is to overhanging or to inside contracting, thereby so that the size reduction of discharge gate or increase, both convenient and strength-saving during adjusting, safety can realize that again discharge gate is in little step-less adjustment simultaneously again.
Description of drawings
Fig. 1 is the structural representation of adjuster of the present utility model;
Fig. 2 is structural representation of the present utility model.
Among the figure: the 1-adjusting seat, the 2-push rod, the 3-adjuster, the 4-jacking block, 5-moves jaw, the 6-discharge gate, 7-decides jaw, the 11-wedge, the 12-screw rod, the 13-sleeve, the 14-support, the 15-adjusting head, 16-locks pipe, and 17-locks screw, 18-stop pin, 19-bearing.
The specific embodiment
As depicted in figs. 1 and 2, the utility model discloses a kind of discharge gate governor motion of jaw crusher, comprise an adjusting seat 1 and push rod 2, have an adjuster 3 and a jacking block 4 in the described adjusting seat 1, two ends of described push rod 2 are rotatably connected with the position of jacking block 4 and moving jaw 5 near discharge gates 6 respectively, adjusting by adjuster 3, jacking block 4 is moved to push rod 2 directions, push rod 2 drives moving jaw 5 and moves to deciding jaw 7 directions, thereby discharge gate 6 is turned down, otherwise, by the adjusting of adjuster 3, make jacking block 4 retractions, push rod 2 drives moving jaw 5 to moving away from deciding jaw 7 directions, thereby discharge gate 6 is tuned up, in sum, basic identical with the version of the discharge gate governor motion of existing jaw crusher.
The innovative point of the discharge gate governor motion of jaw crusher of the present utility model is that mainly described adjuster 3 comprises two wedges 11 of relatively installing, the large end of described wedge 11 is connected with a screw rod 12, described screw rod 12 external screw threads are connected with a sleeve 13, described sleeve 13 is towards an end of wedge 11 support 14 that has been rotatably connected, and described support 14 fixes with adjusting seat 1.During concrete operations, rotate simultaneously the sleeve 13 on two limits, sleeve 13 drives screw rod 12 and connection two wedges 11 thereon are mobile in opposite directions, so that the thickness S of two wedges 11 increases, jacking block 4 is moved to push rod 2 directions, push rod 2 drives moving jaw 5 and moves to deciding jaw 7 directions, thereby discharge gate 6 is turned down; Otherwise, the sleeve 13 on simultaneously opposite spin two limits, sleeve 13 drive screw rods 12 and connection two wedges 11 thereon are from movement, so that the thickness S of two wedges 11 reduces, make jacking block 4 retraction, push rod 2 drives moving jaw 5 to moving away from deciding jaw 7 directions, thereby discharge gate 6 is tuned up.
Described sleeve 13 has an adjusting head 15 away from an end of wedge 11.The rotation of screw rod 12 is put adjusting head 15 by the tool cover of special use usually carry out, the form of described adjusting head 15 can be hexagonal or quadrangle.
In order to make discharge gate 6 sizes that regulate locked, described sleeve 13 overcoats have a locking pipe 16, and described locking pipe 16 is positioned at and has a locking screw 17 on adjusting head 15 positions, is connected with a stop pin 18 on the described locking screw 17.After discharge gate 6 size adjustment are good, stop pin 18 is inserted locking screw 17, adjusting head 15 is lived on the crown of stop pin 18, prevents the rotation of screw rod 12, thereby has locked the size of discharge gate 6.
Described support 14 is provided with bearing 19 with the junction of sleeve 13.By the setting of bearing 19, make the rotation of sleeve 13 more laborsaving, also avoided the wearing and tearing of support 14 with the junction of sleeve 13 simultaneously.
