Description

Technical Field

[0001] This utility model relates to the field of limestone mine drilling, and more specifically, to an open-pit limestone mine drilling device with shock absorption function. Background Technology

[0002] Drilling equipment is an indispensable tool in the mining of open-pit limestone. However, existing drilling equipment for open-pit limestone mines has some shortcomings in practical applications.

[0003] Traditional drilling equipment often generates significant vibration during operation, which not only severely damages the equipment itself and shortens its lifespan, but also affects the accuracy and quality of drilling. Excessive vibration also impacts the equipment's operational stability, making it prone to malfunctions, increasing maintenance costs and downtime, and ultimately reducing work efficiency.

[0004] Secondly, existing drilling equipment typically employs a single linear drilling method, which is often inefficient when faced with complex geological conditions and ore characteristics. Because rotary drilling is not possible, the contact area between the drill bit and the ore is relatively small during the drilling process, requiring more time and energy to complete the drilling task. Therefore, we propose an improvement: an open-pit limestone mine drilling device with vibration damping capabilities. Utility Model Content

[0005] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: an open-pit limestone mine drilling device with shock absorption function, comprising a main frame of the drilling device, a drilling sliding frame mounted on the main frame, C-shaped buffer sliding plates on both sides of the drilling sliding frame, the C-shaped buffer sliding plates cooperating with buffer slide rails, a servo motor mounted on the drilling sliding frame, the servo motor connected to a motor drive roller via a motor shaft, and a conveyor belt cooperating with a driven roller.

[0006] As a preferred technical solution of this utility model, the driven round rod is connected to the main drive shaft, and the end of the main drive shaft is provided with a driving bevel gear.

[0007] As a preferred technical solution of this utility model, the driving bevel gear is engaged with the transmission gear.

[0008] As a preferred technical solution of this utility model, the transmission gear is connected to the gear shaft.

[0009] As a preferred technical solution of this utility model, a piercing drill bit is provided at the lower end of the gear shaft, and the piercing drill bit is provided with conical drill teeth.

[0010] As a preferred technical solution of this utility model, a shock-absorbing rubber block is provided at the connection between the servo motor and the perforated sliding frame.

[0011] As a preferred technical solution of this utility model, the perforated sliding frame is connected to one end of the steel wire body, and the other end of the steel wire body is connected to the steel wire round rod.

[0012] As a preferred technical solution of this utility model, the steel wire roller is connected to an external motor via a rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the coordinated operation of its various components, enables rapid and efficient drilling operations in limestone mines, thus improving work efficiency. The C-shaped buffer sliding plates on both sides of the drilling sliding frame, in conjunction with the buffer slide rails, and the shock-absorbing rubber blocks at the connection between the servo motor and the drilling sliding frame, effectively reduce vibrations generated during operation, minimizing damage and extending the equipment's lifespan. The excellent vibration damping helps improve the equipment's operational stability, reducing errors caused by vibration, thereby improving drilling accuracy and quality. The reasonable connection and coordination between components ensures smoother operation and reduces the probability of malfunctions. The equipment is suitable for drilling operations in open-pit limestone mines and can operate stably in relatively harsh working environments.

[0015] This invention is started by a servo motor on a perforating sliding frame. The motor shaft drives the active roller to rotate, which in turn drives the driven roller to rotate via a conveyor belt. The rotation of the driven roller drives the main drive shaft to rotate, and the active bevel gear at the end of the main drive shaft rotates accordingly. The active bevel gear and the transmission gear cooperate with each other, driving the transmission gear to rotate. The transmission gear drives the perforating drill bit to rotate via a gear shaft. The conical drill teeth on the perforating drill bit perform perforation operations on the limestone ore under the action of rotation, improving the perforation efficiency through rotary perforation.

The drilling sliding frame 2 is connected to one end of the wire body 13, and the other end of the wire body 13 is connected to the wire round rod 14. The wire round rod 14 is connected to an external motor through a rotating shaft.

[0027] The working principle of the open-pit limestone mine drilling equipment with shock absorption function is as follows: An external motor drives the steel wire rod 14 to rotate through a shaft. The rotation of the steel wire rod 14 causes the connected steel wire body 13 to pull the drilling sliding frame 2. The C-shaped buffer sliding plates 21 on both sides of the drilling sliding frame 2 slide along the buffer slide rail 3, which plays a role in buffering and shock absorption.

[0028] The servo motor 4 on the perforated sliding frame 2 starts, driving the motor drive roller 5 to rotate via the motor shaft 41. The motor drive roller 5 drives the driven roller 7 to rotate via the conveyor belt 6.

[0029] The driving bevel gear 81 cooperates with the transmission gear 9, driving the transmission gear 9 to rotate. The transmission gear 9 drives the drilling bit 10 to rotate via the gear shaft 91. The conical drill teeth 11 on the drilling bit 10 perform drilling operations on the limestone ore under the action of rotation.

[0030] The shock-absorbing rubber block 12 installed at the connection between the servo motor 4 and the perforation sliding frame 2 can effectively reduce the impact of the vibration generated by the servo motor 4 during operation on the main frame 1 of the perforation equipment, thereby improving the stability and service life of the equipment.

[0031] The working process of the drilling equipment for open-pit limestone mines with shock absorption function is as follows: Start the external motor, which drives the steel wire rod 14 to rotate through the shaft. The rotation of the steel wire rod 14 causes the steel wire body 13 to pull the drilling sliding frame 2. The C-shaped buffer sliding plates 21 on both sides of the drilling sliding frame 2 slide on the buffer slide rail 3, which plays a role in buffering and shock absorption. At the same time, the drilling sliding frame 2 begins to move.

[0032] Start the servo motor 4 on the perforated sliding frame 2. The servo motor 4 drives the motor drive roller 5 to rotate through the motor shaft 41.

[0033] The motor-driven roller 5 drives the driven roller 7 to rotate via the conveyor belt 6. The rotation of the driven roller 7 drives the main drive shaft 8 to rotate, and the driving bevel gear 81 at the end of the main drive shaft 8 rotates accordingly. The driving bevel gear 81 cooperates with the transmission gear 9, driving the transmission gear 9 to rotate.

[0034] The transmission gear 9 drives the drilling bit 10 to rotate via the gear shaft 91. The conical drill teeth 11 on the drilling bit 10 perform drilling operations on the limestone ore under the action of rotation.

[0035] Example 2: In this example, the main frame 1 of the perforating device is made of high-strength steel to ensure sufficient strength and stability in harsh working environments.

[0040] Example 3: In this example, the main frame 1 of the perforating device is made of aluminum alloy to reduce the overall weight of the device while ensuring its strength and stability. Lubricating oil is added between the C-shaped buffer sliding plate 21 and the buffer slide rail 3 to further reduce friction and wear.

[0041] The servo motor 4 is equipped with an advanced control system that can precisely adjust its speed and torque according to work requirements. Gear transmission is used between the motor shaft 41 and the motor drive roller 5 to improve transmission stability and reliability.
