Description

Technical Field

[0001] The utility model relates to the field of blasting engineering, and more specifically, to a mine drilling device. Background Art

[0002] Mining drilling devices are equipment used to drill holes in rocks in mines, usually composed of a drill, a drill bit, and a drill rod. The drill is a device used to drive the drill bit and drill rod to rotate. The drill bit is used to break rocks, and the drill rod is used to transmit rotational force and withstand the reaction force during drilling. Different types of drilling devices can be selected according to different application scenarios and rock types, such as down-the-hole drills, rotary drills, and impact drills. Down-the-hole drills are suitable for drilling operations in medium-hard rocks, rotary drills are suitable for drilling operations in soft and hard rocks, and impact drills are suitable for drilling operations in soft soil layers.

[0003] A down-the-hole drill will generate a lot of dust when drilling, and is usually equipped with a dust collection device. On the one hand, it can improve the construction environment, and on the other hand, the collected dust can be refilled into the blasting hole. However, the dust collection device discharges the dust through the ash outlet, and the height of the ash outlet is not adjustable. If the ash outlet is higher than the ground, the discharged dust will be affected by the wind and dispersed in the air. If inhaled by construction workers, it will affect their health.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] A mining drilling device, such as Figures 1 to 4As shown, it includes a body 1, on which a drill bit and a connecting plate 2 are provided, on which a collecting box 3 for collecting dust produced by the drill bit is slidably connected, on which an ash outlet 9 is provided, on which a distance sensing device is provided, and between which a connecting plate 2 and the collecting box 3 is provided a control mechanism, for controlling the upward and downward displacement of the collecting box 3 on the connecting plate 2, by setting the collecting box 3 to slide on the connecting plate 2, and at the same time, the control mechanism can adjust the distance between the ash outlet 9 and the ground according to the information of the distance sensing device, so that when the dust comes out of the ash outlet 9, the falling distance of the dust is shorter, thereby reducing the influence of wind on the dust, and further improving the construction environment.

[0022] like Figure 2 and Figure 3 As shown, a sliding groove 4 is opened on the connecting plate 2, and a sliding bar 5 is fixedly connected to the collecting box 3. The sliding bar 5 slides in the sliding groove 4, so that the collecting box 3 can slide on the connecting plate 2. The cross-section of the sliding bar 5 is T-shaped, and the cross-section of the sliding groove 4 is the same as the cross-section of the sliding bar 5, so that the sliding bar 5 keeps sliding in the sliding groove 4. The sliding bar 5 is located on the side of the collecting box 3 close to the ash outlet 9, so that the sliding bar 5 can slide in the sliding groove 4. The opening of the sliding groove 4 is located below the connecting plate 2, and a closing cover 10 for closing the opening position of the sliding groove 4 is fixedly connected to the bottom of the connecting plate 2, so as to limit the sliding of the sliding bar 5, and when the sliding bar 5 conflicts with the closing cover 10, the collecting box 3 and the connecting plate 2 remain flush.

[0023] like Figure 4 As shown, the control mechanism includes two racks 6 and two driving gears 7 meshing with the racks 6. The racks 6 are integrally formed on both sides of the collecting box 3. When the driving gear 7 rotates, the racks 6 are driven to move, and then the collecting box 3 slides on the connecting plate 2. When the driving gear 7 rotates, the racks 6 are driven to move, and then the collecting box 3 slides on the connecting plate 2. Cavities are provided on both sides of the connecting plate 2, and a motor 8 is accommodated in the cavity. The driving gear 7 is connected to the motor 8 by a key. When the motor 8 rotates, the driving gear 7 rotates to realize the displacement of the collecting box 3 on the connecting plate 2.

[0024] Working process: Before drilling in the mine, the operator first moves the collection box 3 downward so that the ash outlet 9 of the collection box 3 is close to the ground. During this process, the driving gear 7 rotates synchronously while the motor 8 rotates. Since the driving gear 7 is engaged with the rack 6, the rack 6 drives the collection box 3 to move toward the ground, and the sliding bar 5 on the collection box 3 slides to the bottom of the sliding groove 4 until the ash outlet 9 is close to the ground.

[0025] When drilling in the mine, the dust collected in the collecting box 3 is gradually discharged from the ash outlet 9, so that the accumulated dust gradually becomes higher. When the distance between the accumulated dust and the ash outlet 9 is less than 10 cm, the distance sensing device sends a signal to the motor 8, causing the motor 8 to rotate, so that the ash outlet 9 rises, until the distance between the ash outlet 9 and the dust is greater than 10 cm, and then the motor 8 stops rotating.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
