[0022] In order to make the above purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail below with reference to the drawings and specific embodiments.

[0023] The utility model provides a kind of ice-breaking mechanical drill bit, such as Figs. 1-2As shown, it includes: a shell 1, a support rod 2, a drill tip 3, a drill blade 4, a plurality of impurity removal grooves 5 and an impurity removal channel 6, the shell 1 is used for fixed connection with the icebreaker; the top end of the support rod 2 extends into the shell 1 and is in transmission connection with the drill bit driving device 7 of the icebreaker; the drill tip 3 is integrally connected to the bottom end of the support rod 2; the drill blade 4 is integrally connected to the outer side wall of the support rod 2 in a spiral shape; each impurity removal groove 5 is arranged on the drill blade 4 and is arranged in a spiral shape along with the drill blade 4; the impurity removal channel has one end connected with the shell 1 and in communication, and the other end is in communication with the outside world, and the drill tip 3 is integrally connected to the bottom end of the support rod 2, which provides a sharp starting point for the drill bit. This integrated connection structure enhances the connection strength between the drill tip 3 and the support rod 2, and when facing the huge resistance of the ice layer, the force can be better concentrated on the drill tip 3, the ice layer can be more effectively cut, the risk of drill tip 3 falling off or damage is reduced, and the service life of the drill bit is prolonged. The spiral-shaped drill blade 4 is integrally connected to the outer side wall of the support rod 2, which has many advantages. The spiral shape can produce a spiral propulsion effect when the drill bit rotates, helping the drill bit to penetrate the ice layer more easily, reducing the dependence on external pressure, and improving the autonomy and efficiency of ice breaking. In addition, the integrated connection design ensures the integrity and strength of the drill blade 4 and the support rod 2, and during high-speed rotation and strong friction, the drill blade 4 will not loosen or fall off, improving the reliability of the drill bit work. The impurity removal grooves 5 are arranged on the drill blade 4 and are spiral-shaped, cooperating with the rotation direction of the drill blade 4, and utilizing the centrifugal force, the impurities and debris generated during the rotation of the drill bit can be quickly and effectively thrown into the impurity removal grooves 5. This design can avoid the accumulation of impurities and debris near the drill bit, prevent their contact with the drill bit and the ice layer, and prevent subsequent interference to the ice breaking operation, thereby maintaining the continuous and efficient ice breaking performance of the drill bit. One end of the impurity removal channel 6 is connected with the shell 1 and in communication, and the other end is in communication with the outside world, which builds a smooth impurity removal path. This communication design ensures that the impurities collected from the impurity removal grooves 5 can be smoothly discharged to the outside environment, ensuring the cleanliness of the internal working environment of the drill bit, thereby avoiding the influence of impurity blockage on the working performance of the drill bit, and ensuring that the drill bit can continuously perform ice breaking operation, improving the running stability of the overall ice breaking equipment.

[0024] In a preferred embodiment, the pitch of the drill blade 4 is 50-150 mm, the width of the drill blade 4 is 10-30 mm, and the drill blade 4 is spiral-shaped, and the pitch can be changed within the range of 50-150 mm according to the thickness and hardness of the ice layer, the width of the blade is 1-3 cm, which can change the cutting depth and angle, and optimize the ice breaking effect.

[0025] In a preferred embodiment, the outer surface of the drill bit 4 is provided with micro grooves or protrusions. The laser etching technology is used to process micro grooves or protrusions on the surface of the spiral drill bit 4. The laser parameters are precisely controlled (energy density 10-20 joules / square centimeter, pulse width 5-10 nanoseconds, scanning speed 5-10 millimeters per second) to achieve uniform distribution of microstructures with a depth of 50-150 microns and a width of 30-100 microns. This structure significantly increases the contact area of the drill bit 4 with the ice layer and can embed into the ice layer, enhancing the friction and overcoming the problem of slipping.

[0026] In a preferred embodiment, the outer surface of the drill bit 4 is coated with a wear-resistant coating. After roughening the surface of the drill bit 4, a tungsten carbide-cobalt (WC-Co) composite coating is applied using a thermal spraying process. The tungsten carbide mass fraction is 80%-90%, the cobalt mass fraction is 10%-20%, and the coating thickness is 100-300 microns. This improves the friction between the drill bit 4 and the ice layer and protects the drill bit 4.

[0027] In a preferred embodiment, the width of the impurity removal groove 5 is 5-10 mm. This width ensures that impurities and debris can be smoothly removed through the impurity removal groove 5 during ice breaking, preventing blockage due to too narrow a groove width, ensuring smooth impurity removal, and facilitating the maintenance of normal ice breaking operations of the drill bit, improving operational efficiency.

[0028] In a preferred embodiment, the pitch between each impurity removal groove 5 is 15-25 mm. This pitch design helps to efficiently throw impurities and debris into the impurity removal groove 5 using centrifugal force when the drill bit rotates, and allows them to be smoothly removed along the impurity removal groove 5, effectively cleaning impurities and debris generated during the process of breaking the ice layer, ensuring the working performance of the drill bit and avoiding interference of impurities with the operation of the drill bit.

[0029] In a preferred embodiment, the length of the support rod 2 is 300-800 mm and the diameter is 100-300 mm. This size range ensures that the support rod 2 has sufficient strength and stability, preventing bending or damage due to structural problems during ice breaking operations of the support drill tip 3 and the drill bit 4, ensuring stable power transmission and reliable operation of the entire drill bit, while also facilitating coordination with the ice breaker.

[0030] In a preferred embodiment, the impurity removal channel 6 is a smooth-walled circular tube structure. The smooth-walled circular tube structure of the impurity removal channel 6 provides a smooth discharge path for impurities and debris discharged from the impurity removal groove 5, reducing the risk of impurities remaining and clogging in the channel, ensuring the stability of the impurity removal effect, and allowing the drill bit to maintain good working condition throughout the entire ice breaking operation.

[0031] In a preferred embodiment, the support rod 2, the drill tip 3 and the drill blade 4 are all made of high manganese steel material, which has good wear resistance, high strength and certain toughness, so that the support rod 2, the drill tip 3 and the drill blade 4 can maintain good performance when facing the friction, impact and other harsh working conditions of ice layer, are not easy to be damaged, prolong the service life of the whole drill bit, and ensure the efficient and stable operation of the ice breaking operation.

[0032] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model.
