[0029] Two pairs of blocking cylinders 10 are arranged on the frame of the tray conveyor 1, and L-shaped blocking plates are arranged at the ends of the piston rods of the blocking cylinders 10. When the piston rods of the blocking cylinders 10 extend, the L-shaped blocking plates are driven to block the seismic charge feeding trays 9.

[0030] The transverse sliding table 3 is a pneumatic sliding table, and the slide of the transverse sliding table 3 is installed on the top of the grasping frame 2.

[0031] The cylinder barrel of the lifting cylinder 4 is vertically installed on the slider of the transverse sliding table 3.
