[0009] In order to effectively improve the loosening efficiency of the removable bucket teeth;

[0010] As a further improvement of the above technical solution: the vibration mechanism includes a motor, a counterweight and a rotating shaft, the motor is installed on the outer shell, the output shaft of the motor is connected to one end of the rotating shaft through a coupling, the rotating shaft is rotatably installed on the outer shell, and the counterweight is eccentrically installed on the rotating shaft.

[0011] The beneficial effect of this improvement is that when the motor is running, it drives the counterweight block to rotate eccentrically, thereby causing the outer shell to vibrate, thereby improving the loosening efficiency of the detachable bucket teeth below.

[0012] In order to conveniently adjust the vibration amplitude of the outer shell;

[0013] As a further improvement of the above technical solution: there are multiple counterweights, which are installed adjacent to each other on the rotating shaft.

[0014] The beneficial effect of this improvement is that the vibration amplitude of the outer shell can be conveniently adjusted by adjusting the number of installed counterweights.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0028] Embodiment 1:

[0029] like Figure 1—4 shows: a mineral mining loosening device, comprising an excavator body 1, the front end of the boom of the excavator body 1 is rotatably connected to the rear side of an outer shell 2 through a pin shaft, the front end of the boom cylinder of the excavator body 1 is rotatably connected to a connecting seat 3 through a pin shaft, the connecting seat 3 is arranged on the outer shell 2, a vibration mechanism 4 is installed on the outer shell 2, a connecting seat 2 5 is arranged on the front side of the outer shell 2, the connecting seat 2 5 is rotatably connected to one end of a loosening cylinder 6 through a pin shaft, the other end of the loosening cylinder 6 is rotatably connected to the upper end of a bucket tooth mounting bracket 7 through a pin shaft, the bucket A detachable bucket tooth 8 is installed at the bottom of the tooth mounting frame 7, and a connecting arm 9 is connected to the rear side of the bucket tooth mounting frame 7. The connecting arm 9 is rotatably connected to the main pin shaft 10 inserted on the outer shell 2. The modification and use of this device has the characteristics of flexible construction and adaptability to different working surfaces, and compared with the blasting method, the safety and environmental protection are effectively improved. The connecting seat 3 is arranged at the upper rear of the outer shell 2. By controlling the extension and contraction of the boom cylinder of the excavator body 1, the angle of the outer shell 2 can be conveniently adjusted to flexibly use the construction angle of the detachable bucket tooth 8 installed below the outer shell 2 The vibration mechanism 4 includes a motor 41, a counterweight 42 and a rotating shaft 43. The motor 41 is installed on the outer shell 2. The output shaft of the motor 41 is connected to one end of the rotating shaft 43 through a coupling. The rotating shaft 43 is rotatably installed on the outer shell 2. The counterweight 42 is eccentrically installed on the rotating shaft 43. When the motor 41 is running, the counterweight 42 is driven to rotate eccentrically, so that the outer shell 2 vibrates, thereby improving the loosening efficiency of the detachable bucket tooth 8 below. The number of the counterweight 42 is multiple, and they are adjacently installed on the rotating shaft 43. By adjusting the counterweight 42 The vibration amplitude of the outer shell 2 can be conveniently adjusted by the number of installations. The bucket tooth mounting frame 7 is provided with a groove structure that is smoothly connected to the upper end surface of the detachable bucket tooth 8. The detachable bucket tooth 8 and the bucket tooth mounting frame 7 are both provided with slots that are adapted to insert bolts 71. The detachable bucket tooth 8 can be firmly installed on the bucket tooth mounting frame 7. The bottom side of the detachable bucket tooth 8 is provided with a reinforcing rib 81, and the reinforcing rib 81 is an arc-shaped groove structure. The setting of the reinforcing rib 81 increases the pressure at the contact point between the detachable bucket tooth 8 and the rock surface, thereby improving the ground-breaking effect of the detachable bucket tooth 8.

[0030] The working principle of this technical solution is: when the loosening cylinder 6 is extended, it drives the bucket tooth mounting frame 7 and the connecting arm 9 to rotate with the kingpin shaft 10 as the support shaft, and the rotating bucket tooth mounting frame 7 drives the detachable bucket tooth 8 at the bottom to move downward to loosen the soil. When the motor 41 is running, it drives the rotating shaft 43 to rotate, and the counterweight block 42 eccentrically installed on the rotating shaft 43 causes the outer shell 2 to vibrate rapidly, thereby improving the loosening efficiency of the detachable bucket tooth 8 connected to the bottom of the outer shell 2.
