[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-way catalytic converter substrate crushing device for platinum group metals, comprising a crushing processing box, a rotating block, a transmission cylinder and a pulley, wherein a shaking frame is provided inside the crushing processing box, the bottoms of both sides of the shaking frame are respectively connected to the two sides of the crushing processing box through return springs, and pulleys are symmetrically connected to the two sides of the bottom of the shaking frame, and a bracket frame is provided at the bottom of the shaking frame, and the bracket frame is fixed to the two sides of the crushing processing box, and the top of the bracket frame is connected to a limiting slide matching the pulley, and the pulley slides along the limiting slide to assist the shaking frame in stabilizing the left and right shaking action;

[0006] A transmission cylinder is fixed on one side of the shaking frame, and a movable opening is connected to one side of the crushing and processing box. The transmission cylinder passes through the movable opening and extends to the outside of the side of the crushing and processing box. The top and bottom of the movable opening are both connected to a guide block 1, and the top and bottom of the transmission cylinder are both connected to a guide groove 1 that matches the guide block 1. The guide block 1 slides along the guide groove 1 to limit the auxiliary transmission cylinder to stably move left and right in the movable opening;

[0007] A rotating block is provided on the side of the transmission cylinder facing away from the crushing and processing box. A force wheel is connected to the top of the rotating block. The force wheel is used to replace the rotating block and repeatedly contact the transmission cylinder, thereby isolating the rotating block and effectively protecting the rotating block.

[0008] The interior of the rotating block is connected with a transmission rod, the rear end of the transmission rod is equipped with a motor, and the motor is fixed to the outside of the crushing processing box through a fixing frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The platinum group metal three-way catalytic converter substrate crushing device drives the rotating block to rotate by cooperating with the transmission rod through the motor. The rotating block will repeatedly contact and push the transmission cylinder with the force wheel during the rotation process. The transmission cylinder can be slidably connected with the guide groove and the guide block to realize repeated left and right movement in the movable mouth. Since the transmission cylinder is fixedly connected to the side of the shaking frame, the shaking frame will be forced to slide along the top of the bracket frame and the corresponding limit sliding groove through the pulley. The shaking frame itself is connected to the two sides of the crushing processing box through the reset spring. The restoring property of the reset spring causes the shaking frame to repeatedly shake, thereby improving the screening effect of the internal coarse material collection box on the crushed material passing through. The coarse material will remain in the coarse material collection box, and the fine material will fall into the fine material collection box for collection, which is convenient for the subsequent coarse and fine material classification and collection operation;

[0018] (2) This platinum group metal three-way catalytic converter substrate crushing device can limit the position of the coarse material collection box to the front side by keeping the limit lever in the state of being limited to the front side of the coarse material collection box due to the expansion of the tension spring 2, so as to facilitate the subsequent removal of the coarse material collection box from the shaking frame and the removal of the coarse material collected in the coarse material collection box. The limit lever can rotate and interact in the movable groove, and one end of the tension spring 2 is movably connected to the guide block 4, so that the guide block 4 can slide along the guide groove 4 to adapt to the rotation of the limit lever, thereby reducing the problem of deformation of the tension spring 2 in the later stage.

[0019] (3) The platinum group metal three-way catalytic converter substrate crushing device can pre-extrude the three-way catalytic converter substrate by setting the extrusion roller, which is convenient for the subsequent crushing work. The setting of the crushing roller can efficiently crush the flattened three-way catalytic converter substrate and improve the crushing uniformity. The setting of the guide plate can guide the three-way catalytic converter substrate dropped from the feed hopper and guide it between the two extrusion rollers, thereby improving the effect of extruding the material and avoiding the problem of material jamming. The restorability of the tension spring can elastically support the guide plate, so that the guide plate can quickly reset when under pressure to maintain the guiding effect.

[0029] A transmission cylinder 7 is fixed to one side of the shaking frame 18, and a movable opening 3 is connected to one side of the crushing processing box 1. The transmission cylinder 7 passes through the movable opening 3 and extends to the outside of the side of the crushing processing box 1. The top and bottom of the movable opening 3 are connected to a guide block 9, and the top and bottom of the transmission cylinder 7 are connected to a guide groove 8 matching the guide block 9. A rotating block 6 is provided on the side of the transmission cylinder 7 away from the crushing processing box 1, and the top of the rotating block 6 is connected to the force wheel 4, and the inside of the rotating block 6 is connected to a transmission rod 33.

[0032] Both sides of the front side of the vibration frame 18 are connected to movable grooves 30. The movable grooves 30 are hinged with limit bars 28 inside. The limit bars 28 can rotate and interact within the movable grooves 30. Then, one end of the second tension spring 31 is movably connected to the fourth guide block 29. The fourth guide block 29 can slide along the fourth guide groove 27 to adapt to the rotation of the limit bars 28, thereby reducing the problem of deformation of the second tension spring 31 in the later stage.

[0033] The top of the limiting blocking rod 28 is connected to a guide groove 27, and a matching guide block 29 is slidably installed in the guide groove 27.

[0038] A tension spring 2 31 is hinged on the guide block 4 29. The expansion of the tension spring 2 31 enables the limit lever 28 to remain in a state limited to the front range of the coarse material collection box 19, which can play a front limit role in the position of the coarse material collection box 19, making it easy to subsequently pull the coarse material collection box 19 out of the shaking frame 18 and to take out the coarse material collected in the coarse material collection box 19.

[0039] The other end of the second tension spring 31 is connected to the inner side of the movable slot 30 .
