Description

Technical Field

[0001] The present application relates to the technical field of ore sampling, and in particular to an ore sampling device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. Ores can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in an ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, while other ores are often expressed in percentages. Ore grade is usually used to measure the value of an ore.

[0003] As the ore is mined, in order to ensure the quality of the ore, it is necessary to sample the ore from time to time so that the grade of the ore can be tested in real time. The mined ore is generally transported by a discharge hopper and a conveyor belt. The ore sampling is usually done by the operator taking the ore from the conveyor belt and then testing it. Manual sampling by operators has the defect of poor sampling randomness, which can easily lead to inaccurate test results. Utility Model Content

[0004] In order to improve the problem of poor randomness in manual sampling by operators, which easily leads to inaccurate test results, the present application provides an ore sampling device.

[0005] The ore sampling device provided in this application adopts the following technical solution:

[0006] An ore sampling device comprises a hopper body and a sampling hopper, wherein a sampling port is provided on the side wall of the hopper body, the sampling hopper is vertically arranged on the outer side wall of the hopper body, the sampling hopper is vertically connected, the sampling hopper is located below the sampling port, a baffle is provided on the hopper body, and an adjustment mechanism is provided on the sampling hopper for driving the baffle to form different degrees of shielding for the sampling port.

[0007] By adopting the above technical scheme, the mined ore is unloaded through the hopper body. When sampling is required, the baffle is driven to move by the adjusting mechanism, the sampling port is opened, and the ore is randomly thrown out through the sampling port and falls into the sampling hopper while being unloaded. The ore falls through the bottom of the sampling hopper and is collected and sampled by the operator. The sampling process is random, which reduces the interference of human factors and improves the accuracy of the test results. When the sampling is completed, the baffle is controlled by the adjusting mechanism to cover the sampling port, which does not affect the normal operation of the hopper body. The structure is simple and easy to use.

[0008] Optionally, the adjustment mechanism includes a linear drive member, the top of the baffle is rotatably connected to the outer side wall of the hopper body along the transverse direction, the output end of the linear drive member is rotatably connected to the side wall of the baffle away from the hopper body, a connecting bracket is provided on the sampling hopper, the fixed end of the linear drive member is rotatably connected to the connecting bracket, and the linear drive member and the rotation plane of the baffle are coplanar.

[0009] By adopting the above technical solution, when sampling is required, the linear drive component is started, and the output end of the linear drive component drives the baffle to rotate, thereby connecting the inner cavity of the sampling bucket and the inner cavity of the hopper body. The ore in the unloading state in the hopper body randomly falls into the sampling bucket and falls from the bottom of the sampling bucket to be sampled. The structural arrangement of the linear drive component and the baffle is simple and easy to use.

[0010] Optionally, a crushing mechanism is provided on the sampling bucket, and the crushing mechanism is used to crush the ore in the sampling bucket.

[0011] By adopting the above technical solution, since the ore grade of each piece of ore has deviations, a larger piece of ore in the sampling may have a greater impact on the test results. The setting of the crushing mechanism enables the ore to be crushed by the crushing mechanism after entering the sampling bucket, and then falls from the bottom of the sampling bucket to be collected and sampled. The operator collects powdered ore with a smaller volume and uniform distribution, which improves the accuracy of the test results; the pre-crushing by the crushing mechanism also reduces the difficulty of carrying for the operator, and there is no need for the operator to crush the ore in the laboratory, which reduces the difficulty of detection.

[0012] Optionally, the crushing mechanism includes a first crushing roller, a second crushing roller and a power piece, the first crushing roller and the second crushing roller are both rotatably connected to the sampling bucket, the first crushing roller and the second crushing roller are both provided with meshing teeth on the peripheral walls, the first crushing roller and the second crushing roller are meshed by the meshing teeth, and the power piece is used to drive the first crushing roller to rotate.

[0013] By adopting the above technical scheme, the ore falling from the sampling port of the hopper body falls on the first crushing roller and the second crushing roller, and the power piece is started to drive the first crushing roller to rotate, which drives the second crushing roller to rotate synchronously, thereby crushing the ore into smaller particles or powder, thereby realizing the functional requirement of the crushing mechanism to crush the ore. The coordinated arrangement of the first crushing roller, the second crushing roller and the power piece has a simple structure and is easy to use.

[0014] Optionally, a shunt tube is connected to the bottom of the sampling bucket, the shunt tube is communicated with the inner cavity of the sampling bucket, and the shunt tube is arranged at an angle.

[0015] By adopting the above technical solution, the setting of the diverter tube can divert the ore falling from the top of the sampling bucket. A small amount of ore randomly falls into the diverter tube and falls along the diverter tube. The operator only needs to collect the ore falling in the diverter tube as a sample. On the one hand, it reduces the sampling cost, and on the other hand, it also increases randomness, thereby improving the accuracy of the test results.

[0016] Optionally, a movable partition is slidably connected to the side wall of the sampling hopper, and the movable partition can slide to separate the diverter tube from the inner cavity of the sampling hopper. The sampling hopper is provided with a locking component for locking the position of the movable partition.

[0017] By adopting the above technical solution, the movable partition is slid after sampling is completed, so that the movable partition separates the diverter tube from the inner cavity of the sampling bucket, and then the position of the movable partition is locked by the locking component, thereby avoiding the waste caused by excess ore flowing out of the diverter tube. The setting of the locking component can also reduce the probability of losing the movable partition.

[0018] Optionally, the locking assembly includes an insertion rod and a return spring, a support block is provided on the sampling bucket, a through hole is formed on the support block, an extension direction of the through hole is perpendicular to the sliding direction of the movable partition, and the insertion rod is passed through the through hole; a socket is formed corresponding to the through hole on the movable partition, one end of the return spring is connected to the support block, and the other end of the return spring is connected to the insertion rod, and the return spring tends to make the insertion rod pass through the through hole and be inserted into the socket.

[0019] By adopting the above technical solution, when the position of the movable partition is adjusted into place, the insertion rod is passed through the through hole and then inserted into the socket corresponding to the through hole, thereby locking the position of the movable partition. The structure is simple and practical. The setting of the reset spring enables the insertion rod to be automatically inserted into the socket under the elastic force of the reset spring, saving time and effort.

[0020] Optionally, the sampling hopper is provided with an inspection compartment door.

[0021] By adopting the above technical solution and setting the maintenance door, the staff can open the maintenance door to repair and clean the inside of the sampling bucket, thereby ensuring the normal progress of the sampling operation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The coordination of the hopper body, sampling hopper, baffle and adjustment mechanism enables the hopper body to be connected with the sampling hopper by adjusting the position of the baffle through the adjustment mechanism when the ore is discharged through the hopper body. The ore falls randomly into the sampling hopper when unloading, and then falls through the bottom of the sampling hopper to be collected and sampled. The sampling process is random, which reduces the interference of human factors and improves the accuracy of the test results.

[0024] 2. The setting of the crushing mechanism enables the ore to be crushed when it falls in the sampling bucket, reducing the probability of inaccurate test results caused by sampling larger pieces of ore; and crushing the ore in advance also reduces the inconvenience caused by the staff in crushing the ore in the laboratory, reducing the difficulty of detection;

[0025] 3. The setting of the diverter tube can divert the ore falling from the sampling bucket. A small amount of ore falls randomly into the diverter tube, and the ore falls from the diverter tube again. The operator only needs to collect the ore samples falling in the diverter tube, which reduces the sampling cost, further increases the randomness of sampling, and improves the accuracy of the test results.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses an ore sampling device. Figure 1The ore sampling device comprises a hopper body 1 and a sampling hopper 2. The hopper body 1 is used to discharge the ore. A horizontal conveyor belt 3 is provided at the bottom of the hopper body 1 to receive the ore falling through the hopper body 1 and transport the ore away. A sampling port 11 is provided on the side wall of the hopper body 1. The sampling hopper 2 is vertically welded and fixed on the outer wall of the hopper body 1 on the side where the sampling port 11 is provided. The upper and lower ends of the sampling hopper 2 are both opened, and the upper end opening of the sampling hopper 2 is located below the sampling port 11 of the hopper body 1.

[0033] The hopper body 1 is rotatably connected with a baffle 4, the baffle 4 has the same shape as the sampling port 11, and the top of the baffle 4 is rotatably connected to the hopper body 1 via a rotating shaft 41, and the baffle 4 can be rotated to completely block the sampling port 11. A connecting bracket 21 is welded and fixed to the sampling hopper 2, and an adjustment mechanism for driving the baffle 4 to block the sampling port 11 to different degrees is provided on the connecting bracket 21.

[0034] When the baffle 4 is driven to open by the adjustment mechanism, the ore randomly passes through the sampling port 11 and falls into the sampling hopper 2 during the process of unloading through the hopper body 1, and falls in the sampling hopper 2, and the operator collects the ore sample under the sampling hopper 2. The ore sampling has a high randomness, which reduces the deviation caused by manual sampling, thereby improving the accuracy and reliability of the test results. When sampling is not required, it is only necessary to drive the baffle 4 through the adjustment mechanism to completely cover the sampling port 11, which does not hinder the normal use function of the hopper body 1.

[0035] The adjustment mechanism includes a linear drive member 211. For example, the linear drive member 211 adopts a telescopic cylinder. The fixed end of the linear drive member 211 is rotatably connected to the connecting bracket 21 through the first rotating rod 212. The telescopic end of the linear drive member 211 is rotatably connected to the side wall of the baffle 4 on the side away from the hopper body 1 through the second rotating rod 213. The first rotating rod 212, the second rotating rod 213 and the rotating shaft 41 are parallel to each other, that is, the linear drive member 211 is parallel to the plane where the baffle 4 rotates. When it is necessary to open the baffle 4 so that the sampling hopper 2 is connected to the hopper body 1, the telescopic cylinder is started to drive the telescopic end of the telescopic cylinder to retract and pull the baffle 4 to open; when sampling is not required, the telescopic cylinder is started to operate in reverse so that the baffle 4 covers the sampling port 11.

[0036] Reference Figure 2 When the ore is transported on the conveyor belt 3, the ore grade of each piece of ore has deviations. A larger piece of ore in the sampling may have a greater impact on the test results. For this reason, a crushing mechanism 5 is provided on the sampling bucket 2. The crushing mechanism 5 is used to crush the ore in the sampling bucket 2, so that the sampling size is uniform and the accuracy of the test results is improved.

[0037] The crushing mechanism 5 includes a first crushing roller 51, a second crushing roller 52 and a power member. The first crushing roller 51 and the second crushing roller 52 are both connected to the middle inner cavity of the sampling bucket 2 in a lateral rotation, and meshing teeth 511 are provided on the outer peripheral walls of the first crushing roller 51 and the second crushing roller 52. The first crushing roller 51 and the second crushing roller 52 are meshed with each other through the meshing teeth 511. The power member is used to drive the first crushing roller 51 to rotate. When the ore sample falls in the sampling bucket 2, it will first fall on the first crushing roller 51 and the second crushing roller 52. At this time, the first crushing roller 51 is driven to rotate by the power member, thereby driving the first crushing roller 51 and the second crushing roller 52 to rotate synchronously, and then the ore is crushed. The crushed ore falls through the bottom of the sampling bucket 2 and is collected and sampled.

[0038] The power part includes a rotating motor 53 and a synchronous belt 54. The rotating motor 53 is bolted and fixed on the sampling bucket 2. A synchronous wheel 55 is coaxially welded and fixed on the rotating shaft of the rotating motor 53 and the first crushing roller 51. The synchronous belt 54 is jointly wound on the two synchronous wheels 55. Starting the rotating motor 53 can drive the first crushing roller 51 to rotate.

[0039] In addition, in order to facilitate the staff to inspect and clean the sampling bucket 2, an inspection port 22 is opened on the sampling bucket 2, and an inspection compartment door 23 is rotatably connected to the inspection port 22 on the sampling bucket 2. By opening and closing the inspection compartment door 23, the interior of the sampling bucket 2 can be inspected and cleaned through the inspection port 22.

[0040] Furthermore, a shunt pipe 6 is connected to the side wall at the bottom of the sampling bucket 2. The shunt pipe 6 is tilted downward, and the top of the shunt pipe 6 is open. The higher end of the shunt pipe 6 goes deep into the inner cavity of the sampling bucket 2. During the falling process of the ore crushed by the crushing mechanism 5, a small part of the ore will randomly enter the shunt pipe 6, and fall along the tilted shunt pipe 6, and be collected and sampled by the operator, and most of the remaining ore will naturally fall to the conveyor belt 3 at the bottom and be transported away. The setting of the shunt pipe 6 allows only a small amount of ore samples to be collected, reducing the sampling cost, and can further increase the randomness of sampling, thereby improving the reliability of the detection results.

[0041] Reference Figure 2-3 In order to be able to block the diversion tube 6 in time after the sampling is completed to avoid ore waste, a movable partition 7 is provided on the side wall of the sampling bucket 2. The movable partition 7 is vertically slid and clamped on the side wall of the sampling bucket 2. When the movable partition 7 slides vertically to the bottom, it can just block the diversion tube 6. The sampling bucket 2 is provided with a locking component 8 for locking the position of the movable partition 7.

[0042] The locking assembly 8 includes a support block 81, an insertion rod 82 and a reset spring. The support block 81 is welded and fixed on the sampling bucket 2, and the support blocks 81 are symmetrically arranged on both sides of the movable partition 7. A sliding engagement cavity for sliding the movable partition 7 is arranged between the two support blocks 81. A through hole 811 is opened horizontally on the upper edge of the support block 81, and the insertion rod 82 is inserted into the insertion hole 71. The movable partition 7 is provided with an insertion hole 71 corresponding to the through hole 811. When the movable partition 7 slides downward until the bottom of the movable partition 7 abuts against the bottom wall of the inner cavity of the diverter plate, the movable partition 7 can block the diverter pipe 6, so that the diverter pipe 6 no longer flows out ore. At this time, the insertion hole 71 of the movable partition 7 is aligned with the through hole 811 of the support seat, the return spring is sleeved on the insertion rod 82, one end of the return spring is welded to the support block 81, and the other end of the return spring is welded to the peripheral wall of the insertion rod 82, and the return spring tends to make the insertion rod 82 pass through the through hole 811 and insert into the insertion hole 71, thereby locking the movable partition 7. The matching arrangement of the insertion rod 82 and the return spring allows the movable partition 7 to be locked more conveniently and quickly, with a simple structure and easy use.

[0043] The implementation principle of the ore sampling device of the embodiment of the present application is as follows: when the ore is discharged through the hopper body 1, the linear drive member 211 is started to drive the baffle 4 to open, so that the hopper body 1 is connected with the sampling hopper 2, and the ore randomly enters the sampling hopper 2 through the sampling port 11 while being discharged. After entering the sampling hopper 2, the ore falls on the first crushing roller 51 and the second crushing roller 52. The ore can be crushed by starting the rotating motor 53 to drive the first crushing roller 51 to rotate. The crushed ore continues to fall in the sampling hopper 2. As the ore continues to fall, a small amount of ore falls into the diverter pipe 6 and flows out from the lower end of the diverter pipe 6. The operator collects and samples the ore flowing out of the diverter pipe 6. By setting the baffle 4 in combination with the sampling bucket 2, the ore can enter the sampling bucket 2 randomly, thereby improving the randomness of sampling and improving the reliability of the test results; the setting of the crushing mechanism 5 can pre-crush the ore, reduce the inconvenience caused by the operators in crushing the ore in the laboratory, and reduce the difficulty of detection; the setting of the diversion pipe 6 further improves the randomness of ore sampling and improves the reliability of the test results.

[0044] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
