DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] 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.

[0033] Referring to Figure 2 、 Figure 4 and Figure 6 , an embodiment provided by the present utility model: a device for explosive loading of a rock drilling jumbo, including a base 1. A robotic arm 3 is fixedly connected to the left side of the top of the base 1. A hollow drill rod 4 is fixedly connected to the left end of the robotic arm 3. A cylinder 5 is fixedly connected to the right side inside the hollow drill rod 4. The output end of the cylinder 5 is fixedly connected to a first piston 6. A connecting rod 7 is fixedly connected to the left end of the first piston 6. A second piston 8 is fixedly connected to the left end of the connecting rod 7. The top end of the hollow drill rod 4 communicates with a transparent hollow barrel 9. A barrel cover 10 is arranged at the top end of the transparent hollow barrel 9. A servo motor 11 is fixedly connected to the middle of the top end of the barrel cover 10. The output end of the servo motor 11 penetrates through the barrel cover 10 and is fixedly connected to a rotating rod 12. Cross-shaped fixing plates 14 are fixedly connected to the peripheries of the bottom of the outside of the rotating rod 12. A sector plate 13 is fixedly connected to the middle and lower part inside the transparent hollow barrel 9. The bottom end of the rotating rod 12 is rotatably connected to the middle of the top end of the sector plate 13. A scale 15 is arranged on the front side of the transparent hollow barrel 9. A limiting mechanism 2 is arranged on the outside of the hollow drill rod 4. The limiting mechanism 2 is used to increase the stability of the hollow drill rod 4 during operation. The gap sizes on the cross-shaped fixing plates 14 respectively match the sizes of the corresponding sector plates 13;

[0034] Specifically, starting the servo motor 11 can drive the rotating rod 12 to rotate, and the sector plate 13 on the rotating rod 12 will rotate synchronously. This design can flexibly adjust the input speed of the explosive according to the angle change between the cross-shaped fixing plate 14 and the sector plate 13. While adjusting the input speed of the explosive, observe the scale 15 on the front side of the transparent hollow barrel 9 to accurately control the input amount of the explosive. This design enables us to easily achieve the effect of quantitative feeding, avoiding the errors and inconveniences that may occur in the manual proportioning process, eliminating the need for manual prior proportioning work, thereby reducing the workload of the staff and meeting the needs of users.

[0035] Referring to Figure 1 、 Figure 4 and Figure 5The limiting mechanism 2 includes a circular ring 201, which is rotatably connected to the middle part of the outer side of the hollow drill rod 4. A plurality of hollow columns 202 are fixedly connected to the left side of the circular ring 201 at equal intervals. A spring 203 is fixedly connected to the right side of the inside of the hollow column 202. A movable column 204 is fixedly connected to the left end of the spring 203. A support plate 205 is fixedly connected to the left end of the movable column 204. Slide blocks 207 are fixedly connected to the front and rear sides of the plurality of movable columns 204. Slide grooves 206 are provided on the front and rear sides of the interiors of the plurality of hollow columns 202. The plurality of slide blocks 207 are slidably connected to the insides of the corresponding slide grooves 206 respectively.

[0036] Specifically, when the hollow drill rod 4 is drilling, the surrounding support plates 205 will first contact the wall to support the hollow drill rod 4. This support design allows the hollow drill rod 4 to maintain a more stable posture during operation, thereby improving the accuracy and efficiency of drilling. Since the area surrounded by the support plates 205 is a triangle, this structural design not only has excellent stability, but also can effectively disperse the pressure and vibration generated by the hollow drill rod 4 during operation. As the hollow drill rod 4 gradually enters the borehole, the support plates 205 will begin to squeeze the corresponding movable columns 204 into the interior of the hollow columns 202. This design allows the support plates 205 to always maintain close contact with the wall, so that the hollow drill rod 4 can always maintain a stable posture during operation without inclination or shaking. This can not only improve the accuracy and efficiency of drilling, but also effectively avoid the occurrence of repeated drilling.

[0037] Reference Figure 1 and Figure 3 The front and rear ends of the top right side of the base 1 are fixedly connected with hydraulic rods 23, and the output ends of the two hydraulic rods 23 are fixedly connected with the same baffle 24. The top of the base 1 is fixedly connected with a fixed rod 19, and the top of the fixed rod 19 is rotatably connected with a turntable 20. The middle part of the top of the turntable 20 is fixedly connected with a controller 21. The controller 21 is electrically connected with the mechanical arm 3, the cylinder 5, the servo motor 11 and the hydraulic rod 23 respectively. A protective cover 22 is arranged on the outside of the controller 21, and one side of the protective cover 22 is rotatably connected with one side of the turntable 20;

[0038] Specifically, the operation of the robot arm 3, the cylinder 5, the servo motor 11 and the hydraulic rod 23 can be controlled by the controller 21, and the protective cover 22 can protect the controller 21 from being damaged by external factors, and the barrier 24 can block the gravel generated by the drilling work, thereby improving the working safety of the device.

[0039] Reference Figure 2 The top front side of the barrel cover 10 is connected with a feed port 17, the top of the feed port 17 is threadedly connected with a sealing cover 18, and the front and rear sides and left and right ends of the base 1 are rotatably connected with walking wheels 25;

[0040] Specifically, explosives can be conveniently injected into the transparent hollow barrel 9 through the feed inlet 17, and the provided sealing cover 18 can prevent the leakage of the materials inside the transparent hollow barrel 9.

[0041] Refer to Figure 2 , bolts 16 are threadedly connected to both the left and right sides of the barrel cover 10, and one end of each bolt 16 sequentially penetrates through the barrel cover 10 and the transparent hollow barrel 9;

[0042] Specifically, the limit fixation of the barrel cover 10 can be released through the bolts 16. At this time, the barrel cover 10 can be removed to perform maintenance work on the structure at its bottom.

[0043] Working principle: When using this device, the staff can start the device and then move it to the working position through the traveling wheels 25. Subsequently, the sealing cover 18 is opened to inject explosives into the transparent hollow barrel 9. Then, the robotic arm 3 is started to drive the hollow drill rod 4 to rotate for drilling the wall surface. After the drilling work is completed, the servo motor 11 and the cylinder 5 are started. The servo motor 11 can drive the rotating rod 12 to rotate. At this time, the sector plate 13 on the rotating rod 12 will rotate accordingly. The explosive input speed can be adjusted according to the angle change between the cross fixing plate 14 and the sector plate 13. Subsequently, by observing the scale 15 on the front side of the transparent hollow barrel 9, the input amount of explosives can be controlled, so as to achieve the effect of quantitative feeding. There is no need for manual prior proportioning work, thus reducing the workload of the staff. The cylinder 5 can push the explosives entering the hollow drill rod 4 into the drill hole, ensuring that the explosives can be correctly placed inside the rock to ensure the effect and safety of the blasting operation;

[0044] And while the hollow drill rod 4 is performing drilling work, the surrounding support plates 205 will first contact the wall surface to support the hollow drill rod 4. Since the area surrounded by the support plates 205 is triangular, the hollow drill rod 4 can be made more stable during operation. As the hollow drill rod 4 enters the drill hole, the support plates 205 will squeeze the corresponding movable columns 204 to make them enter the hollow columns 202, continuously supporting the wall surface, so that the hollow drill rod 4 will not generate an inclination during operation, avoiding repeated drilling, and thus reducing the damage to the wall surface.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
