Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partial view of fig. 1 from direction a.
In the figure: the device comprises a shell 1, a counterattack hanging rack 2, a rotor 3, an adjusting pull rod 4, an adjusting oil cylinder 5, a spring outer sleeve 6, an adjusting plate frame 7, a connecting guide rod 8, a central guide rod 9, a thrust bearing 10, a spring washer 11, a spiral adjusting disc 12, a pressure spring 13 and a locking nut 14.
Detailed Description
As shown in fig. 1-2, the utility model relates to a counterattack formula breaker counterattack stores pylon automatic regulating apparatus, including counterattack formula breaker's casing 1 with articulate in casing 1 around the three counterattack stores pylon 2 of 3 distributions of rotor, be close to its free end difference symmetric connection two regulation pull rods 4 on every counterattack stores pylon 2, it is equipped with adjustment grillage 7 respectively to correspond every counterattack stores pylon 2 punishment in the casing 1 outside, there is adjustment hydro-cylinder 5 at adjustment grillage 7 outside mid-mounting, the cylinder body of adjustment hydro-cylinder 5 passes through the bolt fastening on adjustment grillage 7, it has central guide arm 9 to correspond fixed welding of adjustment hydro-cylinder 5 department on casing 1, the piston rod one end of adjustment hydro-cylinder 5 can be dismantled through the screw with central guide arm 9 and be connected.
The adjusting pull rod 4 penetrates out of the two ends of the shell 1 and the adjusting plate frame 7 respectively, the two ends of the adjusting plate frame 7 are connected with the shell 1 through four connecting guide rods 8 which are uniformly distributed on the periphery of the adjusting pull rod 4 along the circumferential direction, and the inner ends of the connecting guide rods 8 are connected with corresponding screw holes formed in the shell 1 through threads. A certain gap is left between the adjusting plate frame 7 and the shell 1.
The outer end of the adjusting pull rod 4 is respectively connected with a spiral adjusting disc 12 through threads and is sleeved with a pressure spring 13, a spring outer sleeve 6 is sleeved outside the pressure spring 13, the outer port of the spring outer sleeve 6 is sealed, a flange is fixedly welded at the inner end of the spring outer sleeve 6, and the flange is sleeved on connecting guide rods 8 which are uniformly distributed on the circumference through four through holes which are uniformly distributed on the circumference and is fixed with an adjusting plate frame 7 through locking nuts 14 which are arranged on the connecting guide rods 8.
When the gap between the counterattack hanging rack 2 and a striking plate hammer arranged on the rotor 3 needs to be changed, the locking nut 14 is loosened, the adjusting oil cylinder 5 is started through the hydraulic station, hydraulic oil enters the adjusting oil cylinder 5 through the high-pressure oil pipe, the cylinder body of the adjusting oil cylinder drives the adjusting plate frame 7 to move back and forth along the central guide rod 9, the counterattack hanging rack is driven by the adjusting plate frame 7 to move towards the radial direction of the rotor, a graduated scale on the outer side of the shell 1 is observed, when the gap reaches an ideal position, the power supply of the hydraulic station is cut off, the locking nut 14 is screwed, and the gap between the counterattack hanging rack and the rotor is ensured; thereby can accurate quick adjustment ejection of compact granularity, guarantee the finished product proportion of qualified material.
When the uncrushable foreign matters such as iron blocks pass through, the pressure spring 13 cannot bear the instantaneous external force and is compressed at a high speed, so that the whole counterattack hanging rack moves backwards, the gap between the counterattack hanging rack and the rotor is increased by a plurality of times suddenly, the uncrushable foreign matters can be discharged rapidly under the condition of not damaging the workpiece in the machine, and the pressure spring 13 can continue normal crushing operation after recovering the free state, so that the safety coefficient is increased.
