Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a mining blasting sampling device. Background Technology

[0002] Mining blasting sampling refers to the process of collecting representative ore samples from the blasting area during ore mining, especially after blasting operations. This process is crucial for assessing the quality, composition, and distribution of the ore and is an indispensable part of mining engineering.

[0003] Existing mine blasting sampling equipment typically uses cranes to send specialized sampling tubes / cylinders or mechanical lifting devices into the drill pit. The sampling is completed by moving the sampling point around the drill pit. However, the shock waves and rock fragmentation generated during blasting can cause the original drill hole to deform or enlarge, creating sampling blind spots during sampling. This makes it impossible to reach certain specific locations or only surface samples can be collected, affecting the quality of the samples.

[0004] Therefore, a mining blasting sampling device is proposed to solve the problems mentioned above. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please see Figure 1 - Figure 8 A mining blasting sampling device in this embodiment includes a rotating drum 5. Two or more swing devices 7 are fixedly installed on the outer surface of the rotating drum 5. A connecting plate 17 is fixedly connected to the output end of the swing device 7. A support rod 13 is fixedly installed at the end of the connecting plate 17 away from the rotating drum 5. A bucket 6 is fixedly installed on the outside of the support rod 13. The main body of the bucket 6 is inclined. A blade 18 is fixedly installed at the bottom of the bucket 6. A slide groove 14 is fixedly connected to the upper end of the bucket 6. The slide groove 14 has a height difference in the parallel direction with the bucket 6, and the lower side of the slide groove 14 is closer to the rotating drum 5.

[0030] The rotating drum 5 is equipped with a suction pipe 1 inside. A base plate 8 is fitted on the lower half of the outer surface of the suction pipe 1. A motor 9 is fixedly installed on the upper surface of the base plate 8. The rotating drum 5 is placed on the upper surface of the base plate 8.

[0031] Among them, motor 9 is electrically connected to an external power supply. After the mining blasting sampling equipment completes the sampling at the bottom of the drill pit with the assistance of a crane, the bucket 6 is leveled and can be extended into the sampling blind area of ​​the drill pit to contact the ore. Motor 9 drives the rotating drum 5 to rotate. As the quantity accumulates, it gradually rises and falls along the inclined surface of the bucket 6 into the chute 14. The ore slides along the chute 14 to the vicinity of the suction pipe 1, and then the sampling operation is carried out. This can collect the ore in the sampling blind area of ​​the drill pit and improve the quality of the sample.

[0032] One or more clamps 10 are fixedly installed on the lower surface of the chassis 8. A blasting device 4 is installed below the chassis 8. A protrusion 12 is installed at the center of the upper surface of the blasting device 4. One or more lifting rings 11 are installed around the upper surface of the blasting device 4.

[0033] When the suction pipe 1 is sent into the drilling pit, the clamp 10 clamps the lifting ring 11. When the blasting device 4 reaches the bottom of the drilling pit, the clamp 10 releases the lifting ring 11, so that the blasting device 4 can enter the drilling pit together with the suction pipe 1, so as to achieve more precise positioning of the blasting device 4 and ensure that it is in the predetermined optimal blasting position.

[0034] A slurry pump 3 is installed at one end of the suction pipe 1, and a discharge port 2 is installed at the end of the suction pipe 1 near the slurry pump 3.

[0035] The slurry pump 3 is equipped with a filter screen at its inlet to prevent ore from entering its interior and being discharged through the outlet 2. The outlet 2 is connected to an external transport vehicle to avoid mechanical failure or even equipment damage, thus reducing maintenance costs and downtime.

[0036] The swing device 7 has a motor 15 fixedly installed inside, and the output end of the motor 15 is fixedly connected to a rotating shaft 16.

[0037] The output end of the rotating shaft 16 is fixedly connected to the connecting plate 17, and the second motor 15 is electrically connected to an external power source, thereby driving the bucket 6 to swing up and down. Under the drive of the second motor 15, it can be in a vertical state, reducing the overall area occupied by the equipment, thus facilitating the entry and exit of the bucket 6 into the drilling pit. When the ore at the bottom of the drilling pit is insufficient to accumulate to the maximum height of the inclined surface of the bucket 6, the second motor 15 drives the bucket 6 to tilt, and the ore on the surface of the blade 18 can also slide down to the suction port near the suction pipe 1, further improving the quality of the sample.

[0038] The upper surface of the chassis 8 is provided with a groove 19, which is annular, and the lower surface of the rotating cylinder 5 is provided with a convex ring 20.

[0039] The convex ring 20 has the same cross-section as the groove 19. The convex ring 20 is locked in the groove 19, which reduces the amplitude of the rotating drum 5 during rotation, ensures the stability of the equipment during operation, and extends the service life of the equipment.

[0040] The protrusion 12, the rotating drum 5, and the suction pipe 1 are coaxial. The protrusion 12 covers the opening of the suction pipe 1, and the upper surface of the protrusion 12 is in contact with the lower surface of the suction pipe 1.

[0041] When the suction pipe 1 is sent into the drilling pit, the bottom is filled with sealing material and sealed by the protrusion 12. After the clamp 10 releases the lifting ring 11, the suction pipe 1 rises to a certain height and the internal sealing material seals the drilling pit. The crane does not need to work repeatedly, which reduces the time of the sampling process and improves the overall operation efficiency.

[0042] The blade 18 and the slide 14 are set in a parallel state, with the lower end of the slide 14 being lower than the bottom of the suction pipe 1.

[0043] The bottom of the blade 18 is lower than the bottom of the lower end of the slide groove 14, which ensures that the sample scooped up by the blade 18 can fall evenly into the slide groove 14, and avoids the blade 18 being unable to scoop up the sample because it is not at the lowest point and cannot contact the ground.

[0044] The working principle of the above embodiments is as follows:

[0045] During use, the blasting device 4 is sent to the bottom of the pit along with the suction pipe 1. The clamp 10 releases the lifting ring 11, and the suction pipe 1 rises to a certain height. The internal sealing material seals the pit. After the blasting device 4 is detonated, the mining blasting sampling equipment takes samples from the bottom of the pit with the assistance of a crane. The motor 9 is electrically connected to an external power source. The motor 9 drives the rotating drum 5 to rotate, and the cutting edge 18 comes into contact with the ore. As the quantity accumulates, the ore gradually rises and falls along the inclined surface of the bucket 6 into the chute 14. The ore slides down the chute 14 to near the suction pipe 1. The slurry pump 3 performs a suction action on the suction pipe 1. The ore collected by the bucket 6 is sucked into the suction pipe 1 and then output through the discharge port 2. This allows for the collection of ore in the blind sampling area of ​​the pit, improving the quality of the samples.

[0046] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
