DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1 , Figure 2 and Figure 3A mechanical gripper for fixing explosives for dredging a mine chute comprises: a bracket 1; a clamp 2 is arranged on the bracket 1; a universal body 6 is arranged at the center of the bottom of the bracket 1 (equivalent to a kit, and the bottom of the kit is bent toward the central area of ​​the kit so that the ball of the ball head shaft 5 will not move downward from the kit), a ball head shaft 5 is movably arranged in the universal body 6, the ball of the ball head shaft 5 is in the universal body 6, the ball of the ball head shaft 5 can rotate in the universal body 6, the shaft body of the ball head shaft 5 is below the universal body 6, and a mounting plate 4 is arranged on the bottom of the shaft body of the ball head shaft 5.

[0024] Working principle: the clamp 2 is powered on and opened to place the explosive on the bracket 1, and then the clamp 2 is closed until the explosive is clamped and fixed on the bracket 1; the explosive fixing mechanical gripper is moved to make the explosive contact with the bottom of the ore blocking the chute. When the explosive touches an irregular surface, due to the existence of the universal component (the universal component refers to the universal body 6 and the ball head shaft 5. The ball of the ball head shaft 5 rotates in the universal body 6, so that the universal body 6 and the bracket 1 can swing above the ball head shaft 5 to change their own angles), the bracket 1 drives the explosive to swing to achieve a suitable angle, so that the contact surface between the explosive and the blocking ore is more closely fitted, achieving a better adhesion effect, and making the explosive fully fit with the explosion area; after fixing the explosive to the bottom of the blocking ore, the clamp 2 releases the explosive and moves the fixed mechanical arm out of the chute.

[0025] It should be noted that before installing the explosives, a long-distance camera and a long-distance rangefinder are used to observe the internal situation of the chute to confirm the location and height of the blockage; and the surface of the explosives is coated with an adhesive layer so that the explosives can be directly fixed to the bottom of the blocked ore.

[0026] It should also be noted that the mounting plate 4 is connected to the mounting area, and the explosive fixing mechanical gripper is mounted to the mounting area (the mounting area may be a moving device or a mechanical arm, a support rod, and other components).

A clamping nut 10 is provided in the universal body 6, and the clamping nut 10 is located above the universal pressure block 9 to limit the position of the universal pressure block 9. The universal pressure block 9 limits the sphere of the ball head shaft 5 so that it will not move up and down in the universal body 6; a universal seat 7 is provided on the outer wall of the shaft body of the ball head shaft 5, and the top of the universal seat 7 is fitted with the bottom of the universal body 6. A limiting nut 8 is provided on the threaded sleeve on the outer wall of the shaft body of the ball head shaft 5 (a thread is provided on the outer wall of the shaft body of the ball head shaft 5, and the thread matches the limiting nut 8), and a spring 3 is provided between the limiting nut 8 and the universal seat 7; by moving the limiting nut 8 (the limiting nut 8 moves up and down), the supporting force provided by the spring 3 to the universal seat 7 is changed, so that the difficulty of the ball of the ball head shaft 5 rotating in the universal body 6 can be changed.
