[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0018] Combined with Figures 1 to 3 The blasting hole position display device for thick ore body mining comprises a frame 1, and a mounting groove is provided in the frame 1, and an adjusting mechanism 3 and an extending mechanism 4 are respectively installed in the mounting groove, and the rotating end of the adjusting mechanism 3 is meshedly connected with the moving end of the extending mechanism 4, and the extending mechanism 4 is driven to work by the adjusting mechanism 3, and the frame 1 is supported by the extending mechanism 4.
[0019] The frame 1 is a cross-shaped frame.
[0020] The installation groove consists of two movable grooves and a central groove. The two movable grooves are cross-shaped, staggered and not connected. The movable grooves are arranged up and down to avoid movement interference of the rack 401 in the movable groove. The central groove is located in the middle part of the frame 1 and is connected to the two movable grooves.
[0021] The extending mechanism 4 includes a rack 401 and a contact plate 402. The number of the racks 401 is two groups, and the number of each group of racks 401 is two. The two groups of racks 401 are respectively located in two movable grooves and are slidably connected, and the two racks 401 are respectively contacted and connected with the groove walls on both sides of the movable groove. One end of the rack 401 is fixedly connected to the contact plate 402, and the rack 401 is meshed and connected with the rotating end of the adjustment mechanism 3.
[0022] The adjusting mechanism 3 includes a rotating rod 301, a gear 302 and a driving rod. There are two gears 302. The two gears 302 are respectively located on the frame walls on both sides of the central groove and are rotatably connected, and the two gears 302 are respectively meshed with two sets of racks 401. The gear 302 is located between the two racks 401 and is meshed. A through groove is provided on the gear 302, and the groove wall of the through groove is provided with equidistantly arranged clamping grooves. The rotating rod 301 is located in the frame body 1 and is rotatably connected, and the rotating rod 301 is fixedly connected with equidistantly arranged driving rods. The rotating rod 301 is located in the through groove of the gear 302 and is slidably connected, and the driving rod on the rotating rod 301 is slidably connected to the clamping groove.
[0023] The frame 1 is fixedly connected with center circle marking rods 2 which are arranged at equal intervals, and the center circle marking rods 2 are arranged in a circle.
[0024] The device for displaying the position of blasting holes for mining thick ore bodies is used when a worker places the frame 1 on the surface of the ore body and rotates the rotating rod 301. The rotating rod 301 drives one of the gears 302 to rotate through the driving rod on the rod body, and drives one of the racks 401 to move left and right through the rotating gear 302. When the contact plates 402 on the two racks 401 are in contact with the walls on both sides of the ore body, they stop rotating. The rotating rod 301 is pushed or pulled to make the driving rod on the rotating rod 301 move forward. The gear 302 is inserted into another gear 302, and drives the other gear 302 to rotate, so that the contact plates 402 on the two racks 401 are in contact with the walls on both sides. Since the two racks 401 move at the same time, when the rack 401 on one side is in contact with the wall and the rack 401 on the other side is not in contact with the wall, the frame 1 will be driven to move. When the contact plates 402 on both sides are in contact with the wall, the frame 1 will stop moving. After the adjustment is completed, the frame 1 is located in the middle position of the ore body surface, and the position where the blasting hole needs to be drilled is displayed.
