[0001] The invention belongs to the technical field of blasting, and in particular relates to a device for filling blastholes on a step of an open-pit mine. Background Art

[0002] Open-pit mine bench blasting is a key process in open-pit mine production. Its process usually includes preparation, hole layout, drilling, hole inspection, charging, filling, network connection and detonation.

[0003] The prior art has the following problems: the purpose of blasthole filling is to make better use of the energy of the explosive explosion and improve the rock blasting and crushing effect.

When the second ring arm 302 rotates counterclockwise from the first ring arm 301, a circular inward-retracted clamping structure for the outer wall of the slag bin 104 is formed between the multiple clamping shaft arms 309. The pulling arm 308 is rotatably connected to the eccentric wheel body of the driving disk arm 203 at one end away from the first ring arm 301, and the pulling arm 308 is guided and slid in the slide groove seat 204, and the driving disk arm 203 drives the rear end arm body of the pulling arm 308 to draw a circle. At this time, the front end arm body of the pulling arm 308 drives the slag bin 104 to form a universal shaking structure on the top of the outer ball seat 207.

[0020] In summary, the stuffing bin assembly 100 forms a self-vertical straightening longitudinal drilling and longitudinal stuffing structure on the stuffing arm seat assembly 200. By the retracted clamping fixation of the pulling arm assembly 300 and the eccentric rotation drive of the stuffing arm seat assembly 200, the stuffing bin assembly 100 forms an angle-adjustable drilling structure and a stuffing structure on the stuffing arm seat assembly 200. In actual use, the present invention is fixed to an external workbench or a manipulator by bolts and the arm seat 201. At this time, the bottom of the stuffing bin assembly 100 is pressed against the position to be drilled on the step of the open-pit mine, and then the spiral feed plate 107 on the drill shaft 111 and the blasthole drill 10 are driven by the drilling motor 105. 6 rotates, the blasthole drill bit 106 drills and forms a blasthole, the spiral feed plate 107 transports the slag after drilling from the bottom of the filling straight bin 101 to the slag storage bin 104, and the slag of the drilling is temporarily stored in the slag storage bin 104, and then the filling straight bin 101 is pulled out. After the drilling is completed, the explosives and the like are poured into the blasthole of the open-pit mine step. After the preparation work is completed, the filling straight bin 101 is inserted into the blasthole again, and the drilling motor 105 is rotated in the reverse direction. At this time, the spiral feed plate 107 transports the slag in the slag storage bin 104 in the reverse direction and fills it into the blasthole. In this way, it is convenient to collect the slag during drilling and fill the blasthole when the slag is refilled.

[0021] On the basis of the above, when it is necessary to drill a longitudinal blast hole, due to special terrain or the needs of the blast hole, longitudinal drilling is required to ensure the smoothness of subsequent blasting. In order to ensure the longitudinal drilling of the blast hole, the ball head 103 of the present invention is rotatably arranged inside the inner ball seat 110 through the first shaft arm 102 and the bearing, and the inner ball seat 110 is rotatably arranged inside the outer ball seat 207 through the second shaft arm 109 and the bearing. The first shaft arm 102 and the second shaft arm 109 are distributed vertically and horizontally. At the same time, since the gravity of the bottom warehouse body of the straight warehouse 101 is greater than the gravity of the top warehouse body of the straight warehouse 101, under the action of gravity and the vertical and horizontal Under the action of the shaft arm, when the stuffing arm seat assembly 200 is lifted, the stuffing straight bin 101 on the stuffing arm seat assembly 200 is always in a self-vertical and straight longitudinal arrangement state. At this time, the ball head 103 is tightened and fixed by the first cylinder 108, and the inner ball seat 110 is tightened and fixed by the second cylinder 206. In short, through this structure, regardless of whether the stuffing arm seat assembly 200 is vertical or not, the stuffing straight bin 101 on the stuffing arm seat assembly 200 can be in a self-vertical and straight longitudinal arrangement state. In this way, the longitudinal drilling processing and longitudinal filling processing of the open-pit mine step blasthole can be realized.

[0022] On the basis of the above, when there is no need to drill a blasthole longitudinally and it is necessary to tilt or adjust to a certain angle for drilling and filling, the third cylinder 306 is extended to realize the counterclockwise rotation of the second ring arm 302 on the first ring arm 301. When the second ring arm 302 rotates counterclockwise, the second ring arm 302 drives the rear end of the second arc-shaped arm 304 to rotate counterclockwise. Since the first arc-shaped arm 303 is limitedly hinged between the second arc-shaped arm 304 and the first ring arm 301, when the second ring arm 302 rotates counterclockwise, a circular inwardly retracted clamping structure for the outer wall of the slag bin 104 is formed between the arm bodies at the clamping shaft arms 309. At this time, the driving motor 202 The rear end arm of the pulling arm 308 is driven to draw a circle. At this time, the front end arm of the pulling arm 308 drives the slag bin 104 to form a universal shaking structure on the top of the outer ball seat 207. Since the filling straight bin 101 is universally movable in the outer ball seat 207, when the top of the filling straight bin 101 is universally shaken, a reverse swinging structure is formed at the bottom of the filling straight bin 101. Through this swing, when the required drilling and filling angles are adjusted, the rotation of the driving disk arm 203 can be stopped. At this time, the first cylinder 108 and the second cylinder 206 are both extended and tightened to maintain the drilling angle and filling angle of the bottom of the filling straight bin 101, thereby facilitating the drilling and filling requirements at specific angles in different terrains.
