Description

Technical Field

[0001] The utility model belongs to the technical field of hardware tools and relates to a magnetic drill rod for a mine rock drill. Background Art

[0002] The drill rod is a tool for connecting the drill bit and rock drilling in roadway engineering. In mine roadway engineering, the generally used drill rods are hexagonal hollow steel and hollow round steel, usually made of ZK55SiMnMo steel. During the operation of the existing mine rock drill for drilling, the drill rod often breaks accidentally. After breaking, the drill rod remains in the ore and is difficult to take out. It is directly sent to the ore dressing with the ore. After the ore is broken, the broken drill rod cannot be selected by the magnetic separator because it has no magnetism. If the manual decomposition is not complete, it is easy to cause problems such as jamming and damage to the downstream equipment, affecting the continuity and stability of production. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a magnetic drill rod for a mine rock drill aiming at the problems existing in the prior art, and solve the problems that after breaking during the operation of the existing mine rock drill for drilling, the drill rod remains in the ore and is difficult to take out, and it is easy to cause problems such as jamming and damage to the downstream equipment.

[0004] For this reason, the utility model adopts the following technical solutions:

[0005] A magnetic drill rod for a mine rock drill includes a drill rod. The drill rod is hollow, and a water channel is provided through the center. An inlay cavity is arranged in the middle of the water channel. A magnetic tube is embedded in the inlay cavity. One end of the drill rod is provided with a drill bit, and the other end is sequentially provided with a shoulder and a tail. Water outlet holes are arranged through both sides of the drill bit, and a water inlet hole is arranged in the center of the tail. The water inlet hole and the water outlet holes are communicated with the water channel.

[0006] Further, the distances between the two ends of the inlay cavity and the water outlet holes and the shoulder are 50-100 mm respectively, and the distances increase with the increase of the length of the drill rod.

[0007] Further, the magnetic tube and the water channel are concentrically arranged, and the inner diameter is the same as that of the water channel.

[0008] The beneficial effects of the utility model are as follows:

[0009] By arranging a magnetic tube in the drill rod, the utility model makes the drill rod magnetic, and can be separated from the ore by the magnetic separator when the drill rod breaks accidentally and remains in the ore, eliminating the adverse factors such as jamming of the equipment caused by the broken drill rod directly entering the ore dressing process, and ensuring the stable operation of the ore dressing equipment. Description of the Drawings

[0010] Figure 1 is a three-dimensional schematic diagram of the utility model;

[0011] Figure 2 It is a partial sectional view of the present utility model;

[0012] Figure 3 is Figure 2 an enlarged schematic view.

[0013] In the figure, 1 is a drill rod, 2 is a drill bit, 3 is a drill shoulder, 4 is a drill tail, 5 is a water inlet hole, 6 is a water outlet hole, 7 is a magnetic tube, 8 is a water channel, and 9 is an inlay cavity. Specific embodiments

[0014] The technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] As Figures 1 to 3 shown, a magnetic drill rod for a mining rock drill includes a drill rod 1. The drill rod 1 is hollow and is provided with a through water channel 8. An inlay cavity 9 is provided in the middle of the water channel 8. A magnetic tube 7 is embedded inside the inlay cavity 9. One end of the drill rod 1 is provided with a drill bit 2, and the other end is successively provided with a drill shoulder 3 and a drill tail 4. The drill bit 2 is provided with a water outlet hole 6 penetrating through both ends thereof. A water inlet hole 5 is provided at the center of the drill tail 4. The water inlet hole 5, the water outlet hole 6 are communicated with the water channel 8.

[0016] In addition, the distances between the two ends of the inlay cavity 9 and the water outlet hole 6 and the drill shoulder 3 are 50 - 100 mm respectively, and the distance increases with the increase of the length of the drill rod 1. The magnetic tube 7 is concentric with the water channel 8, and the inner diameter of the magnetic tube 7 is the same as the size of the water channel 8.

[0017] In addition, according to different uses and working environments, the short drill rod may not be provided with a water channel. The magnetic tube 7 embedded in the center thereof can be replaced with a cylindrical magnetic rod. The magnetic rod is respectively 5 mm or close to 5 mm away from the drill bit 2 and the drill shoulder 3. The drill bit 2 and the drill tail 4 of the medium drill rod and the long drill rod can be formed by forging in one step, or can be assembled by split thread connection.

[0018] By embedding the magnetic tube 7 in the drill rod 1, the present utility model makes the drill rod 1 magnetic, so that it can be separated from the ore by a magnetic separator in case of accidental fracture, eliminating the adverse factors such as jamming of the equipment caused by the broken drill rod 1 directly entering the ore dressing process, and ensuring the stable operation of the ore dressing equipment.
