[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5

[0027] Embodiment 1 provides a hole cleaning device for open-pit blasting:

[0028] Two sets of support seats 11 are fixedly connected to the bottom of the carrier frame 10. A through groove is formed at the top of the carrier frame 10. The two sets of support seats 11 are placed on the ground to play an overall supporting role.

[0029] The support plate 20 is movably connected to the carrier frame 10 through an adjustment assembly 30. A disk body 21 is rotatably arranged on the support plate 20. The adjustment assembly 30 can drive the support plate 20 to move vertically.

[0030] The air charging assembly 40 includes a compressed air pump 41 installed on the disk body 21 and an air charging pipe 42 eccentrically arranged on the disk body 21. The air charging pipe 42 passes through the disk body 21 and extends downward. A guide air hose 43 is arranged at the outlet end of the compressed air pump 41. The guide air hose 43 is connected to the air charging pipe 42. The compressed air pump 41 supplies compressed air to the air charging pipe 42 through the guide air hose 43.

[0031] When cleaning the blast hole, the air charging pipe 42 is vertically aligned with the blast hole. The adjustment assembly 30 drives the support plate 20 to move downward, driving the air charging pipe 42 into the blast hole. Compressed air is discharged from the bottom opening of the air charging pipe 42 to impact impurities such as broken stones inside the blast hole, so that the impacted broken stones and other impurities can move upward and leave the blast hole. Moreover, the support plate 20 plays a blocking role for the broken stones and other impurities to prevent them from splashing randomly.

[0032] A telescopic part 22 is arranged on the lower side of the support plate 20. The telescopic part 22 is connected with a retaining ring 23 that can cover the top of the blast hole. The telescopic part 22 includes a telescopic rod 221 and a spring 222 wound around the telescopic rod 221. The retaining ring 23 is connected to the bottom end of the telescopic rod 221, so that after the retaining ring 23 covers the top of the blast hole, the telescopic part 22 is compressed to maintain stability. The retaining ring 23 plays a blocking role for the top of the blast hole, so that the broken stones and other impurities that move upward and leave the blast hole will not re-enter the blast hole on the ground.

[0033] A rubber ring 231 is arranged at the bottom of the retaining ring 23. The rubber ring 231 contacts the ground to seal the gap, further improving the blocking effect.

[0034] The power assembly 50 is used to drive the disk body 21 to drive the air impact pipe 42 to deflect in the blast hole. The power assembly 50 includes a motor body 51 installed on the support plate 20. A main gear 52 is provided at the output end of the motor body 51, and a driven gear 53 is provided on the disk body 21. The main gear 52 meshes with the driven gear 53, so that the air impact pipe 42 deflects in the blast hole to flush out impurities such as crushed stones at different positions in the blast hole, effectively improving the cleaning effect of the blast hole.

[0035] Embodiment 2 provides a blast hole cleaning device for open-pit blasting:

[0036] Linear rails 32 are respectively provided on the two inner side walls of the carrier 10. Guide blocks 33 are provided at both ends of the support plate 20. The guide blocks 33 correspond to the linear rails 32 one by one and are fitted together. The adjusting assembly 30 includes an electric cylinder body 31 installed on the carrier 10, and the movable rod of the electric cylinder body 31 is connected to the support plate 20.

[0037] The position of the support plate 20 can be adjusted by the telescopic movement of the movable rod of the electric cylinder body 31, and the guide block 33 on the support plate 20 is slidably fitted with the linear rail 32 on the carrier 10, which plays a guiding role in the vertical movement of the support plate 20.

[0038] Flexible brush strips 44 are provided on the outer wall of the air impact pipe 42, and the flexible brush strips 44 can contact the inner wall of the blast hole.

[0039] During the process of the air impact pipe 42 entering the blast hole downward, the power assembly 50 drives the disk body 21 to drive the air impact pipe 42 to deflect in the blast hole. The flexible brush strips 44 contact the inner wall of the blast hole, brushing off unstable and easily falling impurities such as crushed stones remaining on the inner wall of the blast hole, which can be discharged together when cleaning the blast hole.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
