Description

Technical Field

[0001] This utility model relates to the technical field of slag removal devices, and in particular to a slag removal device for a down-the-hole hammer drill rod rotating blade. Background Technology

[0002] Down-the-hole hammer drills, as a highly efficient rock drilling device, are widely used in mining, geological exploration, and engineering construction. During drilling operations, slag removal is a crucial step, as its effectiveness directly impacts drilling efficiency, equipment lifespan, and operational safety.

[0003] Currently, among the existing down-the-hole hammer drill slag removal equipment, such as the patent with announcement number CN119102490A, the invention discloses a large-diameter down-the-hole hammer positive circulation slag removal auxiliary device, including: a telescopic cylinder, a first connecting component, and a second connecting component; the telescopic cylinder includes multiple nested cylinders, and adjacent cylinders are telescopic; the cylinder is hollow inside and open from top to bottom, and can pass through the drill rod that drives the down-the-hole hammer; the first connecting component is placed at the free end of the outermost cylinder of the telescopic cylinder.

[0004] However, during the use of the device, it was found that the device was not very effective in transporting rock debris using airflow, which reduced the efficiency and reliability of slag removal. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a slag removal device for the rotating blades of a down-the-hole hammer drill rod that improves the slag removal efficiency of rock debris, while also enhancing dust absorption and reducing dust pollution.

[0006] This utility model discloses a rotary blade slag removal device for a down-the-hole hammer drill rod, comprising a cylinder and a down-the-hole hammer, with the hammer positioned below the cylinder. It also includes a collection device, a crushing device, a rotating shaft, spiral blades, and a drive motor. The rotating shaft is rotatably mounted inside the cylinder, with its bottom end connected to the top of the down-the-hole hammer. The spiral blades are mounted on the outer wall of the rotating shaft. The drive motor is mounted at the top of the cylinder, with its output end concentrically connected to the rotating shaft. The collection device is connected to the upper part of the cylinder and is used to collect rock debris within the cylinder. The collection device also draws air from the cylinder. An inlet is located at the bottom of the cylinder, and the crushing device is positioned at the air inlet. The drive motor drives the rotating shaft to rotate, causing the down-the-hole hammer to rotate and crush the rock. The rock debris is conveyed into the cylinder through the inlet. Simultaneously, the rotating shaft drives the spiral blades to rotate, causing them to convey the rock debris entering the cylinder upwards into the collection device. The collection device draws air from the cylinder, thereby improving the slag removal efficiency and dust absorption, and reducing dust pollution.

[0007] Preferably, the collection device includes a vibration device, a collection cylinder, a conveying pipe, a closed door, a filter screen, a top plate, and a fan. The collection cylinder is connected to the cylinder body through the conveying pipe. An outlet is provided at the bottom of the collection cylinder, and the closed door is located at the outlet. The filter screen is installed inside the collection cylinder through the vibration device, which drives the filter screen to vibrate. The top plate is installed at the top opening of the collection cylinder, and the fan is installed at the top of the top plate. The fan input end is connected to the inside of the collection cylinder. The fan draws air into the collection cylinder, causing the collection cylinder to draw air into the cylinder body through the conveying pipe. This allows the rock fragments to be conveyed and discharged by airflow. The rock fragments are conveyed to the collection cylinder through the conveying pipe and filtered by the filter screen, thus storing the rock fragments inside the collection cylinder. The rock fragments are cleaned and discharged by periodically opening the closed door.

[0008] Preferably, the crushing device includes a frame, a first cutter, a mounting base, and a second cutter. The frame is located at the bottom inlet of the cylinder. Multiple sets of first cutters are mounted on the outer wall of the frame, the mounting base is mounted on the outer wall of the rotating shaft, and multiple sets of second cutters are mounted on the mounting base. After the rotating shaft rotates, it drives the multiple sets of second cutters to move circumferentially through the mounting base, so that the multiple sets of second cutters cooperate with the multiple sets of first cutters to cut and crush the rock fragments entering the cylinder again, thereby improving the convenience of conveying and discharging the rock fragments.

[0009] Preferably, the vibration device includes telescopic rods, springs, and a vibration motor. Multiple sets of telescopic rods are arranged between the collection cylinder and the filter screen, multiple sets of springs are respectively installed on the multiple sets of telescopic rods, and the vibration motor is installed on the filter screen. By turning on the vibration motor, the filter screen vibrates under the support of multiple sets of telescopic rods and multiple sets of springs, thereby improving the convenience of cleaning the filter screen by vibration.

[0010] Preferably, it also includes multiple sets of latches, which are set between the collection cylinder and the top plate; this improves the convenience of loading and unloading the top plate and the convenience of internal maintenance of the collection cylinder.

[0011] Preferably, it also includes a flow guide platform, which is set at the bottom of the collection cylinder; the flow guide platform guides the rock debris in the collection cylinder to improve the smoothness of slag discharge.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the drive motor drives the rotating shaft to rotate, which in turn drives the down-the-hole hammer to rotate and crush the rock. The rock fragments are transported into the cylinder through the inlet. At the same time, the rotating shaft drives the spiral blades to rotate, which in turn transports the rock fragments into the cylinder upwards, so that the rock fragments enter the collection device. At the same time, the collection device sucks air into the cylinder, thereby improving the slag discharge efficiency of the rock fragments, improving the dust absorption effect, and reducing dust pollution.
