Description

Technical Field

[0001] This invention belongs to the field of sampling machine technology and relates to a full-section rotary automatic raw coal sampling machine. Background Technology

[0002] Coal mine sampling is the process of extracting a small, representative sample from a large quantity of coal for analysis, testing, and identification of coal quality characteristics. Its core purpose is to reflect the average quality of the entire batch of coal through a small sample, providing a scientific basis for coal processing, utilization, and resource development.

[0003] Chinese patent disclosure CN206818481U discloses a rotary full-section sampling device at the end of a coal conveyor belt. The document states that the sampling device includes a sampling head and a roller, the sampling head being welded to the roller via a connecting arm; the sampling head is an elongated receiving groove; the roller is rotatably mounted on a bearing seat to drive the sampling head to rotate and intercept the coal flow scattered by the coal conveyor belt across its entire cross-section. In one embodiment, the sampling device further includes a coal sample hopper for receiving the coal sample intercepted by the sampling head. In one embodiment, the width of the sampling head is not less than the width of the coal flow scattered by the coal conveyor belt. In another embodiment, the… The distance between the sampling head and the coal conveyor belt is not less than 500mm. In one embodiment, the sampling device further includes a drive motor and a reducer. The drive motor drives the drum to rotate, and the reducer reduces the speed of the drive motor. In one embodiment, the rotation of the drum drives the sampling head to rotate, and the rotation direction of the sampling head is consistent with the rotation direction of the drum at the head of the coal conveyor belt. The sampling device provided in this embodiment is installed at the head of the coal conveyor belt, without any contact with the coal conveyor belt, only with the coal flow. Furthermore, the sampling head has a semi-circular open design, and its rotation direction is opposite to the throwing direction of the coal flow, thus avoiding coal sticking and coal block jamming.

[0004] However, in the above scheme, since the coal block has a certain weight, after the coal is cut and received, it still needs to be thrown to the dropping position. This can easily shorten the service life of the sampling equipment under long-term sampling impact, and the coal block is also easy to break under impact, making it difficult to accurately sample the size of the raw coal. Therefore, it is necessary to design a full-section rotary automatic raw coal sampler. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a full-section rotary automatic raw coal sampler to solve the problem that, due to the weight of the coal, after the coal is cut and received, it still needs to be thrown to the dropping position, which easily causes the service life of the sampling equipment to be shortened under long-term sampling impact, and the coal is also easy to break under impact, making it difficult to accurately sample the size of the raw coal.

[0006] To achieve the above objectives, this invention discloses a full-section rotary automatic raw coal sampler, comprising:

[0007] Conveyor support;

[0008] A first conveyor belt is fixedly connected to one side of the conveyor support, and a second conveyor belt is fixed to the other side of the conveyor support. The first conveyor belt is located above the second conveyor belt and is away from the second conveyor belt.

[0010] A sampling mechanism mounted on the top of a fixed frame, the sampling mechanism including a hopper;

[0011] A buffer plate is mounted on one side of the top of the hopper, and a shock-absorbing damper is mounted on one side of the bottom of the hopper. The sampling mechanism extends to a position below an output position of the conveyor belt, and the buffer plate and the shock-absorbing damper are in rotational contact.

[0012] A collection mechanism is mounted on the side of the shock absorber and damper. The sampling mechanism is rotatably connected to the collection mechanism. An auxiliary flipping mechanism is provided between the sampling mechanism and the collection mechanism. The auxiliary flipping mechanism can assist the sampling mechanism in rotating to one side of the collection mechanism.

[0013] A conveying mechanism fixed on both sides of the collection mechanism, and a sliding positioning mechanism fixed on both sides of the collection mechanism.

[0014] The further improvement of the full-section rotary automatic raw coal sampler of the present invention is as follows:

[0015] Furthermore, the buffer plate is hinged to the hopper for rotation, and the sampling mechanism further includes:

[0016] A baffle fixed to the top of the hopper is used to protect the buffer plate from rotating at the hinge point between the hopper and the buffer plate.

[0017] Furthermore, the middle part of the side of the hopper is rotatably connected to the top end of the collecting mechanism via a hinge.

[0018] Furthermore, the collection mechanism includes:

[0019] A support frame that slides on the top of a fixed frame, wherein the side of the support frame away from the sampling mechanism and the top are hollow;

[0020] A sampling drawer is inserted inside the support frame and is attached to the inner wall of the support frame. The sampling drawer is used to receive the sample taken out by the sampling mechanism.

[0021] Furthermore, a handle is fixedly connected to the side of the sampling drawer away from the sampling mechanism, and the handle is used to pull out the sampling drawer.

[0022] Furthermore, the auxiliary flipping mechanism includes:

[0023] A V-shaped groove is formed on both sides of the support frame, and a U-shaped positioning ring is fixedly connected to the bottom of the side of the V-shaped groove away from the hopper;

[0024] A motor box is fixed to the top of the support frame, away from the hopper. A motor is fixedly connected to the side wall inside the motor box, and a take-up shaft is fixedly connected to the output end of the motor.

[0025] A steel wire rope is inserted inside the U-shaped positioning ring. One end of the steel wire rope is fixed to the top of the hopper, and the other end of the steel wire rope is fixed to the winding shaft. The other end of the steel wire rope is wound around the outside of the winding shaft.

[0026] Furthermore, the position of the U-shaped positioning ring is lower than the hinge rotation position between the hopper and the support frame.

[0027] Furthermore, the conveying mechanism includes:

[0028] Fixing bracket two is fixed to the top of fixing bracket one;

[0029] Motor 2 is fixed to both sides inside the fixed frame 1, and gears are fixedly connected to the output end of motor 2;

[0032] Furthermore, a sliding positioning mechanism is provided on both sides of the collecting mechanism, the sliding positioning mechanism comprising:

[0033] The sliders are fixed to both sides of the support frame, and the slide grooves are opened on both sides inside the second fixing frame. The sliders slide inside the slide grooves.

[0034] The present invention has the following beneficial effects:

[0035] In specific operation, the full-section rotary automatic raw coal sampler of this invention uses a buffer plate to reduce material breakage when the hopper intercepts coal. The auxiliary tilting mechanism is activated to pull the sampling mechanism to rotate, thus pouring the coal into the collection mechanism for collection. Then, the conveying mechanism is activated to simultaneously output from both the collection and sampling mechanisms. During the output process, a sliding positioning mechanism provides positioning, thus solving the problem that because coal lumps have a certain weight, after interception and collection, they still need to be thrown to the drop position, which easily shortens the service life of the sampling equipment under long-term sampling impacts. Furthermore, coal lumps are easily broken under impact, making it difficult to accurately sample the size of the raw coal. Attached Figure Description

The auxiliary turning mechanism 7 is activated to pull the sampling mechanism 5 to rotate, so that the coal can be poured into the collection mechanism 6 for collection. Then, the conveying mechanism 8 is activated to output the coal simultaneously to the collection mechanism 6 and the sampling mechanism 5. During the output process, the sliding positioning mechanism 9 is used for positioning.

[0055] In a further preferred embodiment of the present invention, the buffer plate 502 is hinged to the hopper 501 for rotation, and the sampling mechanism 5 further includes a baffle 503 fixed to the top of the hopper 501, the baffle 503 being used to protect the position where the buffer plate 502 and the hopper 501 are hinged to rotate.

[0057] In a further preferred embodiment of the present invention, the middle part of one side of the hopper 501 is rotatably connected to one end of the top of the collecting mechanism 6 by a hinge, and the hopper 501 is adapted to rotate to the top of the collecting mechanism 6.

[0058] In this embodiment, the material can be easily discharged by rotating the hopper 501 to the top of the collecting mechanism 6.

[0059] In a further preferred embodiment of the present invention, the collection mechanism 6 includes: a support frame 601 that slides against the top of the fixing frame 4; the support frame 601 is hollow on the side away from the sampling mechanism 5 and at the top; and a sampling drawer 602 inserted into the support frame 601, the sampling drawer 602 being attached to the inner wall of the support frame 601, and the sampling drawer 602 being used to receive the sample taken out by the sampling mechanism 5.

[0060] In this embodiment, the sampling drawer 602 enables the collection of samples output by the sampling mechanism 5, making it convenient to extract and send them for testing.

[0062] In this embodiment, the sampling drawer 602 can be manually removed by means of the handle 603.

[0065] In this embodiment, starting the motor 705 can wind up the wire rope 703, thereby enabling the hopper 501 to rotate and tilt to discharge the material, reducing the impact of spillage on the coal.

[0066] In a further preferred embodiment of the present invention, the position of the U-shaped positioning ring 702 is lower than the hinge rotation position between the hopper 501 and the support frame 601.

[0067] In this embodiment, by setting the U-shaped positioning ring 702 at a lower position, the hopper 501 can be tilted into the interior of the V-shaped groove 701 during the winding of the steel wire rope 703, which facilitates material unloading.

[0071] In this embodiment, by placing the second motor 802 in the middle of both sides of the first fixed frame 4, the support frame 601 can be effectively pushed to output.

[0072] In a further preferred embodiment of the present invention, a sliding positioning mechanism 9 is provided on both sides of the collecting mechanism 6. The sliding positioning mechanism 9 includes: a slider 901 fixed to both sides of the support frame 601, and a groove 902 opened on both sides inside the fixing frame 801. The slider 901 slides inside the groove 902.

[0073] In this embodiment, the slider 901 and the groove 902 can be used to position the support frame 601 during the sliding process.

[0074] In summary, the coal is intercepted by the hopper 501, and the buffer plate 502 buffers the coal to reduce breakage. The auxiliary turning mechanism 7 pulls the sampling mechanism 5 to rotate, which can pour the coal into the collection mechanism 6 for collection, further reducing the breakage caused by spillage. Then, the conveying mechanism 8 is started to output the coal to the collection mechanism 6 and the sampling mechanism 5 at the same time. During the output process, the sliding positioning mechanism 9 is used for positioning.
