[0028] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The inner cavity of the mounting member 1 is provided with a mounting sleeve 10, which is arranged vertically (according to Figure 1 As shown in the direction, a push rod 5 is slidably provided in the inner cavity of the mounting sleeve 10 (the push rod 5 can move up and down in the inner cavity of the mounting sleeve 10), and a spring member 18 (spring) is provided between the mounting sleeve 10 and the push rod 5. When the push rod 5 is completely in the inner cavity of the mounting sleeve 10, the spring member 18 is in a compressed state.

[0029] See also Figure 4 , Figure 5 , Figure 7 and Figure 8 , a driving assembly is provided in the mounting member 1, and the driving assembly includes a linkage member and a driving member 13;

[0030] Among them, the linkage part includes a first connecting rod 11 and two second connecting rods 12, the first connecting rod 11 is rotatably arranged in the inner cavity of the mounting member 1 (the middle part of the first connecting rod 11 is installed in the inner cavity of the mounting member 1 through a pin shaft), one end of the two second connecting rods 12 is respectively hinged to the two ends of the first connecting rod 11, and the ends of the two second connecting rods 12 away from the first connecting rod 11 are respectively hinged to the two fixed blocks 4, the driving member 13 is an electric cylinder, and the moving end of the electric cylinder is hinged to the first connecting rod 11; a third connecting rod 14 is slidably arranged in the inner cavity of the mounting member 1, the third connecting rod 14 is hinged to the first connecting rod 11, and a limit stopper 15 is hinged in the inner cavity of the mounting member 1 (one end of the limit stopper 15 is hinged in the inner cavity of the mounting member 1 through a pin shaft), and the other end of the limit stopper 15 is hinged to the third connecting rod 14, and a limit groove 19 is provided on the side wall of the push rod 5, and the side wall of the limit stopper 15 is inserted in the limit groove 19 to limit the movement of the push rod 5.

[0031] It should be noted that the mounting member 1 is mounted on a telescopic support (such as an electric telescopic rod), and the worker moves the explosive fixing gripper by holding the telescopic support.

[0032] Working principle: the electric cylinder extends when working, pushing the first connecting rod 11 to rotate, so that the two second connecting rods 12 move with the two fixing blocks 4 to the outside of the mounting member 1. In this process, the push rod 5 is pressed into the inner cavity of the mounting sleeve 10. Since the movement of the first connecting rod 11 will move the third connecting rod 14, the limit block 15 is inserted into the inner cavity of the limit groove 19 to restrict the push rod 5; a layer of cloth is wrapped around the outside of the explosive, and holes are opened on both sides of the cloth, and then glue is applied to the top of the cloth, and the explosive is placed on the top of the mounting member 1, and the two fixing blocks 4 are inserted into the holes of the cloth to fix the explosive (the fixing blocks 4 tighten the cloth to fix the explosive on the top of the mounting member 1); the staff holds the telescopic pillar and moves the gripper to the chute After the explosive contacts the bottom of the ore, the electric cylinder contracts and rotates the first connecting rod 11 in the opposite direction, so that the second connecting rod 12 moves with the fixing block 4 toward the inside of the mounting member 1, relaxes the taut cloth, and releases the fixing of the fixing block 4 to the explosive; the third connecting rod 14 will be reset as the first connecting rod 11 moves, and the limit stopper 15 is moved out of the inner cavity of the limit groove 19, thereby releasing the restriction on the push rod 5. Under the action of the spring member 18, the push rod 5 moves upward, and pushes the explosive upward, so that the explosive contacts the bottom of the ore fully. After the explosive is fixed to the bottom of the ore (bonded by the glue on the cloth), the staff moves the pillar, moves the gripper out of the inside of the ore chute, and then detonates the explosive to clear the ore blocking the ore chute.

[0033] In this embodiment, as a further optimized solution, please refer to Figure 1 and Figure 4 There are several mounting sleeves 10 and push rods 5, and several mounting sleeves 10 are linearly distributed on the mounting member 1 (according to Figure 4 In the direction shown, several mounting sleeves 10 are arranged in sequence from left to right); the explosives are lifted up by multiple push rods 5 so that the explosives can fully contact the bottom of the ore, ensuring that the explosives can be stably fixed at the bottom of the ore.

[0034] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6, a spring 9 is provided at the bottom of the mounting member 1, a mounting plate 8 is provided at the bottom end of the spring 9, a pressure block 16 is provided at the top of the mounting plate 8, a switch 17 is provided at the bottom of the mounting member 1, and the switch 17 is located directly above the pressure block 16. The switch 17 is used to control the contraction of the extended electric cylinder. A power supply assembly 2 (battery) is installed on the mounting member 1, and the switch 17 is connected in series with the electric cylinder and the power supply assembly 2; the telescopic support held by the staff is connected to the mounting plate 8. When the telescopic support is moved to make the explosive contact with the bottom of the ore, the spring 9 is squeezed and contracted, so that the mounting plate 8 is moved closer to the mounting member 1, so that the pressure block 16 presses the switch 17, the power supply of the electric cylinder is turned on, and the electric cylinder is contracted, so as to realize the automatic contraction of the fixed block 4 and the automatic lifting of the push rod 5, thereby increasing the automation level of the gripper; and the mounting plate 8 is connected to the mounting member 1 through the spring 9. Since the spring 9 is flexible, the mounting member 1 can turn relative to the mounting plate 8. When the bottom of the ore is skewed and uneven, the explosive can rotate when it contacts it, so that the explosive is fully in contact with the bottom of the ore, ensuring that the explosive is fixed and stable.

[0035] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 2 and Figure 3 A camera assembly 3 (camera) is provided on the side wall of the mounting member 1, and the camera assembly 3 is powered by the power supply assembly 2; the camera assembly 3 captures the situation at the bottom of the ore and reports it to the staff, so that the staff can select the installation position of the explosives according to the image, and the explosives can be accurately installed, thereby improving the effect of explosive blasting and dredging.

[0036] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 2 and Figure 3 A plurality of buffer columns 6 are provided on the side wall of the mounting member 1. The buffer column 6 comprises a set, a support rod slidably inserted in the inner cavity of the set, and a spring installed between the set and the support rod. The moving direction of the support rod is the same as that of the push rod 5. When the gripper approaches the bottom of the ore with the explosive, the buffer column 6 first contacts the bottom of the ore, which has a buffering effect, so that there will be no collision between the explosive, the mounting member 1 and the ore, thereby protecting both.

[0037] In this embodiment, as a further optimized solution, please refer to Figure 1 and Figure 3 , retaining bars 7 are evenly arranged around the top of the mounting member 1; they are used to limit the explosive on the top of the mounting member 1.

[0038] In this embodiment, as a further optimized solution, please refer to Figure 1 and Figure 2The mounting member 1 includes a shell 101 and a shell cover 102, and the shell cover 102 is installed on the top of the shell 101 by bolts; the bolts are removed so that the shell cover 102 can be removed from the top of the shell 101 to open the interior of the mounting member 1 so as to facilitate the inspection or replacement of the components inside the mounting member 1.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
