Description

Technical Field

[0001] This invention relates to a sample grinding and powder preparation receiving device and method, used for grinding and powder preparation, belonging to the field of mineral sampling and preparation. Background Technology

[0002] In the field of mineral sample preparation, grinding equipment is required to grind samples to the required particle size. During the sample grinding process, the final collection of samples is a crucial step. On the one hand, it is necessary to avoid material pollution in the environment during collection, and on the other hand, the loss rate should be as low as possible. Currently, grinding devices on the market use a direct collection method, that is, sample bottles are placed directly at the outlet of the grinder. During the grinding process, samples that meet the particle size requirements fall directly into the sample bottles through the sieve holes at the bottom of the grinder. The problems with this direct collection method are: serious residue in the grinding chamber, which can easily cause mixing with the next batch of samples. At the same time, the loss rate is high and it causes environmental pollution.

[0003] Based on the shortcomings of existing grinders, a novel sample grinding and powder preparation receiving device and method that can reduce the residual amount in the grinding chamber, reduce the loss rate, and reduce environmental pollution has become the goal pursued by those skilled in the art.

[0021] The bottle receiving mechanism includes: a bottle receiving mechanism bracket mounted on the frame; the bottle receiving mechanism bracket includes a mounting plate perpendicular to the direction of movement of the translation module; a vertically adjustable mounting seat is provided on the mounting plate; a rotary drive mechanism is mounted on the mounting seat; a corresponding bottle clamping cylinder is provided at the lower end of the mounting seat; the rotary drive mechanism is connected to the tail end of the bottle clamping cylinder and is used to drive the bottle clamping cylinder to rotate 180 degrees left and right; the free end of the bottle clamping cylinder is provided with a clamping arm for clamping the sample bottle; a vertical power mechanism is mounted on the bottle receiving mechanism bracket and connected to the mounting seat for driving the mounting seat to rise and fall; when the rotary drive mechanism drives the bottle clamping cylinder to rotate to one side of the transfer bottle mechanism, the sample bottle clamped by the clamping arm is located between the left and right bottle clamping rods above the mounting seat plate of the bottle clamping mechanism.

[0022] This invention also provides a method for sample grinding and powder preparation and receiving, characterized by comprising the following steps:

[0023] Feeding: The sample is conveyed to the grinding mechanism; the sample bottle is transferred to the first receiving position, the grinding mechanism is started to grind and the first sample is received;

[0024] Once the rated grinding time is reached, stop grinding, remove the sample bottle, connect the second receiving mechanism to the grinding mechanism outlet, and transfer the sample bottle to the second receiving position.

[0025] Start the grinding mechanism and supply high-pressure air into the grinding chamber of the grinding mechanism. At the same time, start the cyclone separator to blow air into the grinding chamber and perform secondary sample collection.

[0026] Then remove the sample bottle and output it.

[0027] Specifically, the sample grinding and powder preparation method is as follows: the sample is conveyed to the grinding mechanism by activating the feeding component of the grinding mechanism to convey the grinding sample into the grinding chamber of the grinding component of the grinding mechanism;

[0028] The transfer bottle mechanism receives sample bottles from the receiving bottle mechanism and transports them to the bottle placement assembly of the first receiving mechanism at the first sample receiving position. The bottle placement assembly is raised to align the sample bottle with the outlet of the feed pipe of the grinding assembly. At the same time, the power assembly of the grinding assembly is started to perform grinding and the first sample receiving.

[0029] Once the rated grinding time has been reached, proceed to the next step;

[0030] The transfer bottle mechanism moves the sample bottle to the second receiving mechanism: the bottle placement component of the first receiving mechanism is lowered; the transfer bottle mechanism removes the sample bottle.

[0031] The cyclone separator of the second receiving mechanism is rotated so that the feed pipe of the cyclone separator is aligned with the outlet of the feed pipe at the lower end of the grinding assembly.

[0032] The transfer bottle mechanism delivers the sample bottles removed from the first receiving position to the bottle placement component two of the second receiving mechanism;

[0033] The second lifting power device of the second receiving mechanism drives the bottle placement assembly to rise, so that the sample bottle is connected to the outlet of the cyclone separator. The second lifting power device continues to drive the bottle placement assembly to rise, which in turn drives the cyclone separator to rise, so that the inlet of the feed pipe of the cyclone separator is connected to the outlet of the feed pipe at the lower end of the grinding mechanism.

[0034] Perform the second sample collection: Start the high-pressure air compressor connected to the grinding chamber of the grinding assembly to supply high-pressure gas into the grinding chamber. At the same time, start the negative pressure mechanism of the cyclone separator to collect the remaining sample in the grinding chamber through the cyclone separator of the second receiving mechanism for the second sample collection. When the rated time is reached, turn off the high-pressure air compressor and the negative pressure mechanism of the cyclone separator to stop grinding.

[0035] Sample bottle removal: The second lifting power device of the second receiving mechanism drives the bottle placement assembly to descend, so that the inlet of the cyclone separator's feed pipe is separated from the outlet of the lower feed pipe of the grinding mechanism. When the cyclone separator stops descending, the bottle placement assembly descends further, so that the sample bottle on the bottle placement assembly is separated from the outlet of the cyclone separator. The transfer bottle mechanism takes out the sample bottle and transports it to the bottle receiving mechanism.

[0036] The cyclone separator of the second receiving mechanism rotates, causing the feed pipe of the cyclone separator to separate from the outlet of the feed pipe at the lower end of the grinding mechanism.

[0037] By employing the aforementioned technical solution, this invention arranges a first and a second receiving mechanism side-by-side below the grinding device. During the grinding process, a sample is collected simultaneously with the grinding, allowing nearly 95% of the sample to be collected directly through the first receiving. The remaining sample is then collected through the cyclone separator assembly of the second receiving mechanism. Cyclone separation uses negative pressure to collect the residual sample in the grinding chamber. This secondary receiving improves the sample collection rate and reduces the loss rate, increasing the collection rate to 98%-99% and reducing the amount of residue in the grinding chamber. Another advantage is that it avoids confusion with the next batch of samples, ensuring the authenticity of the samples.

[0038] Furthermore, this invention provides fixing plates on the sides of the first and second receiving positions for mounting the first and second receiving mechanisms, and a transfer bottle mechanism on the other side of the first and second receiving positions for transferring sample bottles. The first receiving mechanism drives the bottle placement assembly one via a lifting power device, allowing the sample bottles on the bottle placement assembly one to directly connect with the discharge port at the lower end of the grinding mechanism, completing the first sample receiving. The second receiving mechanism achieves secondary sample receiving through a cyclone separator assembly. Specifically, the inlet pipe of the cyclone separator can selectively connect with the discharge port at the lower end of the grinding mechanism. The bottle placement assembly two is driven by a lifting power device two to raise and lower the sample bottles to connect with the outlet of the cyclone separator. During secondary sample receiving, the inlet of the cyclone separator's inlet pipe is aligned with the discharge port at the lower end of the grinding mechanism. The lifting power device two drives the bottle placement assembly two to raise the sample bottles, connecting them with the discharge port at the lower end of the grinding mechanism. The bottles continue to rise until the inlet of the cyclone separator's inlet pipe connects with the discharge port at the lower end of the grinding mechanism, thus achieving secondary sample receiving. In particular, the cyclone separator is rotatably mounted on the cyclone support. The cyclone separator can be driven to rotate between two positions: receiving and non-receiving. When it is in the receiving position, the inlet of the cyclone separator's feed pipe is aligned with the outlet at the lower end of the grinding mechanism. When it is in the non-receiving position, it rotates away from the position below the outlet at the lower end of the grinding mechanism.

[0039] Furthermore, this invention provides two air blowing holes on the grinding base and grinding cover, connected to a high-pressure compressed air compressor via a pipeline equipped with a one-way valve. This allows for simultaneous secondary sample reception, during which high-pressure compressed air is blown into the grinding chamber, dislodging samples adhering to the inner wall of the chamber. These samples are then recovered via a cyclone separator in the second receiving mechanism, further reducing the loss rate and achieving the goal of cleaning the grinding chamber. Furthermore, the sample bottle transfer mechanism of this invention utilizes a translation module and a bottle clamping mechanism to transfer sample bottles. Specifically, the two clamping rods of the clamping mechanism, the left and right disc portions with meshing teeth at their ends, are driven by a reciprocating drive mechanism to rotate the left clamping rod around the center of the left disc portion. The meshing of the teeth on the left and right disc portions enables the opening and closing of the left and right clamping rods.

[0040] In summary, the present invention has an ingenious design concept, a simple structure, and a reasonable layout. It can realize automatic secondary sample collection and automatic transfer of sample bottles, effectively reducing the sample loss rate and achieving a sample recovery rate of 98% to 99%.

Detailed Implementation

[0056] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these preferred embodiments should not be used to limit the scope of protection of the present invention.

[0057] See Figure 1-19The figure shows a sample grinding and powder preparation receiving device according to the present invention, which includes: a grinding mechanism 1, a transfer bottle mechanism 3, and a receiving mechanism; the grinding mechanism 1 is installed on the top of the frame 7 and is used to grind the sample; the receiving mechanism is installed on the frame 7 and located below the grinding mechanism 1; a first receiving position is located below the lower outlet of the grinding mechanism 1, and a second receiving position is provided adjacent to the first receiving position; the receiving mechanism includes a first receiving mechanism 4 and a second receiving mechanism 5, the first receiving mechanism 4 is located below the lower outlet of the grinding mechanism 1, and the second receiving mechanism 5 is located at the second receiving position; the transfer bottle mechanism 3 is used to transfer sample bottles, is installed on the frame 7 below the grinding mechanism 1, and is located on the side of the first receiving position and the second receiving position, that is, the transfer bottle mechanism 3 and the receiving mechanism are located on both sides of the first receiving position and the second receiving position, respectively; The first receiving mechanism 4 includes a bottle placement assembly 41 that can be raised and lowered to hold sample bottles. By raising and lowering the bottle placement assembly 41, the sample bottles can be directly connected to and disconnected from the lower outlet of the grinding mechanism 1 for receiving and placing samples. The second receiving mechanism 5 includes a cyclone separator assembly 53 located at the second receiving position. The cyclone separator assembly 53 includes a cyclone separator 532. The inlet of the cyclone separator 532 can be selectively connected to the lower outlet of the grinding mechanism 1. Selective means that it can be connected when the second receiving mechanism 5 needs to receive samples, and it is not connected when the first receiving mechanism 4 receives samples. Below the outlet of the cyclone separator 532, there is a bottle placement assembly 51 that can be raised and lowered to hold sample bottles. By connecting the inlet of the cyclone separator 532 to the lower outlet of the grinding mechanism 1, the sample bottles are placed on the bottle placement assembly 51 for secondary sample receiving. This invention, by setting up two sample receiving mechanisms: a first receiving mechanism 4 and a second receiving mechanism 5, allows for the first sample receiving during the grinding process, enabling most samples to fall directly into the sample bottle. Then, the second receiving mechanism is activated, employing a cyclone separator. Through negative pressure, the sample remaining in the grinding chamber enters the sample bottle through the cyclone separator outlet. This further improves the sample recovery rate, reduces the loss rate during sample preparation, and ensures the authenticity of the sample preparation.

[0058] See Figure 9-15Specifically, the first receiving mechanism 4 includes a fixed plate 44 vertically mounted on the frame 7. The fixed plate 44 is located on the side of the first receiving position and the second receiving position. A linear rail 42 is vertically arranged on the side of the first receiving position on the fixed plate 44. A bottle placement assembly 41 is slidably connected to the linear rail 42. The bottle placement assembly 41 is located at the first receiving position and is used to place sample bottles. A lifting power device 43 is located on the upper part of the back of the fixed plate 44. The lifting power device 43 is connected to the bottle placement assembly 41 and is used to drive the bottle placement assembly 41 to move up and down along the linear rail 42, that is, to switch between the first receiving position at the lower end outlet of the grinding mechanism 1 and the bottle placement position below the first receiving position. The lifting power device 43 includes a motor 431. Located on the upper part of the back side of the fixed plate 44, a lifting screw 432 is longitudinally arranged on the back side of the fixed plate 44. A belt drive mechanism 433 is connected between the motor 431 and the lifting screw 432 to drive the lifting screw 432 to rotate. The bottle placement assembly 41 includes a horizontal bottle placement plate 411 and a back plate 412 perpendicular to the bottle placement plate. Two sliders 413 that are slidably connected to the linear guide 42 are provided on the back side of the back plate 412. A reinforcing rib plate perpendicular to the two plates can be provided between the back plate 412 and the bottle placement plate 411. A nut connector 414 passes through a longitudinal hole on the fixed plate 44 and is connected to the back plate 412. The nut connector 414 is provided with a nut 415 that is threadedly connected to the lifting screw 432. The motor 431 drives the belt transmission mechanism 433 to rotate the lifting screw 432. The nut 415 and the nut connector 414 drive the back plate 412 and the bottle placement plate 411 to rise and fall. When the bottle placement plate 411 falls to the low position, it is used to receive the sample bottle transferred by the bottle clamping mechanism 32. When it rises to the high position, the sample bottle is located at the lower end of the grinding seat 121, which is used to receive the ground sample.

[0059] The second receiving mechanism 5 includes: a bottle placement assembly 51, a linear guide rail 52, a cyclone separator assembly 53, and a lifting power device 55. The linear guide rail 52 is parallel to and arranged side-by-side with the linear guide rail 42 on the fixed plate 44. The bottle placement assembly 51 is located at the second receiving position and is used to place sample bottles. The bottle placement assembly 51 and the linear guide rail 52 are slidably connected. The cyclone separator assembly 53 is located on the linear guide rail 52 and above the bottle placement assembly 51. A lifting power device 55 is located on the back of the fixed plate 44. In this example, the lifting power device 55 is an electric push rod, which is connected to the bottle placement assembly 51 and is used to drive the bottle placement assembly 51. The bottle-feeding assembly 51 moves up and down, specifically between the bottle-feeding position and the sample-receiving position. The second bottle-feeding assembly 51 includes a horizontal bottle-feeding plate 511 and a back plate 512 perpendicular to the bottle-feeding plate 511. Two sliders 513, slidably connected to the linear guide 52, are located on the back of the back plate 512. An electric push rod is connected to the back plate 512, and its structure is the same as that of the first bottle-feeding assembly 41. A stop block 54 is fixed to the fixed plate 44. The stop block 54 is used to prevent the cyclone separator assembly 53 from descending. When the cyclone separator assembly 53 descends to the stop block 54, the feed pipe 536 of the cyclone separator 532 disengages from the lower outlet of the grinding mechanism 1.

[0060] The cyclone separator assembly 53 includes the cyclone separator 532 located at the second receiving position. The feed inlet on the side of the cyclone separator 532 is connected to the lower outlet of the grinding mechanism 1 through the feed pipe 536. The bottle placement assembly 51 carries the sample bottle and is connected to the lower outlet of the cyclone separator 532. The exhaust pipe of the cyclone separator 532 is connected to the negative pressure mechanism 56. The second lifting power device 55 can drive the second bottle placement assembly 51 to rise to the receiving position. At this time, the sample bottle on the second bottle placement assembly 51 connects with the lower outlet of the cyclone separator 532 and continues to rise, pushing the cyclone separator 532 upward until the feed pipe 536 connects with the lower outlet of the grinding mechanism 1. Then, it stops moving and receives the sample. After the sample is received, the second lifting power device 55 drives the second bottle placement assembly 51 to descend. When the stop block 54 stops the cyclone separator 532 from continuing to descend, the cyclone separator 532 disengages from the lower outlet of the grinding mechanism 1 and continues to descend, so that the sample bottle disengages from the lower outlet of the cyclone separator 532. The sample bottle is then taken out by the transfer bottle mechanism 3 (described in detail later).

[0061] See Figure 11-13The cyclone separator assembly 53 further includes a cyclone support 535, which includes a flat plate 5351 and a vertical plate 5352 vertically arranged behind the flat plate. A slider 5353 connected to the second linear guide 52 is provided on the back of the vertical plate 5352. The flat plate 5351 is used to mount the cyclone separator 532. The slider 5353 on the back of the vertical plate 5352 of the cyclone support 535 allows the cyclone support 535 to be slidably connected to the second linear guide 52. The top plate of the cyclone separator 532 is rotatably mounted on the flat plate 5351 of the cyclone support 535 via a bearing 534. A horizontal feed pipe 536 is connected to the side wall of the cyclone separator 532. The lower end of a feed hopper 533 communicates with the feed pipe 536, and its upper end is used to connect with the lower end of the discharge pipe 14 (described in detail later) of the grinding mechanism 1. The lower outlet of the separator 532 is located above the horizontal plate of the bottle-dispensing assembly 51. A driving component 537 is provided on the top plate of the cyclone separator 532, and a rotating power mechanism 531 is provided on the cyclone support 535. In this embodiment, the rotating power mechanism 531 is a cylinder. One end of the cylinder is hinged and fixed to a vertical plate of the cyclone support 535, and the other telescopic end is hinged to the driving component 537. It is used to drive the cyclone separator 532 to rotate around its center. When the cylinder extends, the feed hopper 533 of the cyclone separator 532 is just connected to the lower end of the discharge pipe 14. The second receiving mechanism 5 is in working state. When the cylinder retracts, the feed hopper 533 of the cyclone separator 532 is just moved away from the lower end of the discharge pipe 14. At this time, the second receiving mechanism 5 is in a non-receiving state, and the first receiving mechanism 4 is in a receiving state.

[0062] See Figure 2-8 The grinding mechanism 1 includes a power component 11, a grinding component 12, a feeding component 13, and a discharge pipe 14. The power component 11 provides grinding power to the grinding component 12, the feeding component 13 provides grinding sample to the grinding component 12, and the discharge pipe 14 is connected to the lower outlet of the grinding component 12 for discharging the sample.

[0063] Specifically, the power assembly 11 includes a motor 111 and a belt drive device 112. The driven pulley of the belt drive device 112 is located at the outer end of the grinding spindle 124 of the grinding assembly, and the driving pulley is located on the output shaft of the motor. The belt connects the driving pulley and the driven pulley.

[0064] The grinding assembly 12 includes a grinding base 121 and a grinding cover 122. The grinding base 121 is mounted on the top of the frame 7, and the upper part of the grinding base 121 and the grinding cover 122 enclose a closed grinding chamber 120. A grinding spindle 124 is horizontally positioned via a support portion 125 fixed at one end to the rear of the grinding base 121. One end of the grinding spindle 124, which extends into the grinding chamber 120, is connected to a striking block 123. The other end of the grinding spindle extends from the shaft support portion 125 and is connected to a motor 111 via a belt drive device 112. The lower part of the grinding chamber 120 has a screen 126, and a feed pipe 14 is connected to an outlet at the lower end of the grinding base 121 for material discharge. See also Figure 3-8 Another feature of the present invention is that at least one air hole 1211 and at least one air hole 1221 are respectively arranged on the grinding seat 121 and the grinding cover 122. The air hole 1211 is radially arranged on the rib plate from the outer circular wall of the grinding seat 121 and then bends at 90 degrees to communicate with the horizontally arranged hole. The air hole 1221 is directly arranged in the hole parallel to the axial direction of the grinding cover 122. In this embodiment, there are three air holes 1211 and three air holes 1221. The air holes 1211 and 1221 are respectively connected to a high-pressure compressed air machine through pipes, and the pipes are equipped with one-way valves. By providing air blowing holes in the grinding base 121 and the grinding cover 122, a high-pressure compressed air compressor can be turned on to blow high-pressure air into the grinding chamber 120 during secondary material receiving. Thus, the pressurized air blown out of the first air blowing hole 1211 on the grinding base 121 can fall onto the sample on the grinding cover 122, and the pressurized air blown out of the second air blowing hole 1221 on the grinding cover 122 can fall onto the sample on the grinding base 121. This allows for further sample recovery, reduces the loss rate, and also achieves the purpose of cleaning the grinding chamber, preventing the current sample from being mixed into the next batch of samples, and ensuring the authenticity of the samples.

[0065] The feeding assembly 13 includes: a feeding hopper 131, and a screw feeder 132 located at the bottom end of the feeding hopper 131 and connected thereto. The outlet of the screw feeder 132 is connected to the inlet at the center of the grinding cover 122 of the grinding assembly 12. The sample enters the screw feeder 132 through the feeding hopper 131 at the upper end of the screw feeder 132, and is evenly pushed into the grinding chamber of the grinding assembly 12 by the screw rod of the screw feeder 132, which can achieve uniform feeding.

[0066] See Figure 19 , 20The bottle receiving mechanism 2 includes: a bottle receiving mechanism support 21 mounted on the frame 7.

Specifically, it includes: a second motor 261 mounted on the motor mounting base 212 and a lead screw 262 connected to the second motor 261. The mounting base 22 has a second nut connector 222 screwed to the lead screw 262. The second motor 261 drives the lead screw 262 to rotate, further driving the mounting base 22 to rise and fall; a rotary drive mechanism 23 is mounted on the mounting base 22. A bottle-clamping cylinder 24 is provided at the lower end of the mounting base 22.

A cylinder connector 232 with a driven gear at its upper end is connected to the tail end of the bottle-clamping cylinder 24 and is connected by electricity. The gear driven by the rotary drive mechanism 23 rotates in both directions, enabling the bottle clamping cylinder 24 to rotate 180 degrees left and right. The free end of the bottle clamping cylinder 24 is provided with a clamping arm 25 for clamping the sample bottle. When the rotary drive mechanism 23 drives the bottle clamping cylinder 24 to rotate to one side of the transfer bottle mechanism 3, the sample bottle clamped by the clamping arm 25 is located between the left clamping rod 321 and the right clamping rod 321' above the mounting base plate 323 of the bottle clamping mechanism 32. When the bottle clamping cylinder 24 rotates to the side away from the transfer bottle mechanism 3, it is used to receive the sample bottle transported from the outside. During operation, the rotary drive mechanism 23 drives the bottle-clamping cylinder 24 to rotate to the side away from the transfer bottle mechanism 3 to receive the sample bottle. It then rotates 180 degrees to the side of the transfer bottle mechanism 3. Next, the vertical power mechanism 26 drives the mounting base 22 to descend onto the mounting base plate 323. The bottle-clamping cylinder 24 releases, and the left and right bottle-clamping rods 321 and 321' close to clamp the sample bottle and transfer it to the receiving position.

[0069] Furthermore, a vibrator 57 is provided on the side wall of the cyclone separator 532 and the feed hopper 533; a vibrator 133 is also provided on the feed hopper 131 of the feeding assembly 13. Through vibration, the sample is dislodged and prevented from adhering to the side wall of the cyclone separator 532, the feed hopper 533 and the feed hopper 131.

[0070] The present invention also provides a sample grinding and powder preparation method, which includes the following steps:

[0071] Feeding: Convey the sample to grinding mechanism 1;

[0072] The sample bottle is transported to the first sample receiving position, and the grinding mechanism 1 is started to grind and receive the first sample.

[0073] When the rated grinding time is reached, stop grinding, remove the sample bottle, connect the second receiving mechanism to the outlet of grinding mechanism 1, and transfer the sample bottle to the second receiving position;

[0074] Start the grinding mechanism 1 and supply high-pressure air into the grinding chamber of the grinding mechanism 1. At the same time, start the cyclone separator to blow air into the grinding chamber and perform secondary sample collection.

[0075] Then remove the sample bottle and output it.

[0076] Specifically, the feeding step includes: conveying the sample to the grinding mechanism 1: starting the feeding component 13 of the grinding mechanism 1 to convey the grinding sample to the grinding chamber 120 of the grinding component 12 of the grinding mechanism 1;

[0077] The sample bottle is transported to the first receiving position and the grinding assembly 12 is started to perform grinding and the first sample receiving. Specifically, the transfer bottle mechanism 3 receives the sample bottle and transports it to the bottle placement assembly 41 of the first receiving mechanism 4 at the first receiving position. The bottle placement assembly 41 is raised to align the sample bottle with the outlet of the grinding assembly 12. At the same time, the power assembly 11 of the grinding assembly 12 is started to perform grinding and the first sample receiving.

[0078] Once the rated grinding time has been reached, proceed to the next step;

[0079] Transfer the sample bottle to the second receiving mechanism: lower the bottle placement component 41 of the first receiving mechanism 4; the transfer bottle mechanism 3 removes the sample bottle;

[0080] The cyclone separator 532 of the second receiving mechanism 5 is driven to rotate, so that the feed pipe 536 of the cyclone separator 532 is aligned with the lower outlet of the grinding assembly 12.

[0081] The transfer bottle mechanism 3 delivers the sample bottle taken from the first receiving position to the bottle placement component 51 of the second receiving mechanism 5;

[0082] The second lifting power device 55 of the second receiving mechanism 5 drives the bottle placement assembly 51 to rise, so that the sample bottle is connected to the outlet of the cyclone separator 532. The second lifting power device 55 continues to drive the bottle placement assembly 51 to rise, which in turn drives the cyclone separator 532 to rise, so that the inlet of the feed pipe 536 of the cyclone separator 532 is connected to the lower outlet of the grinding mechanism 1.

[0083] To perform the second sample collection: Start the high-pressure compressed air compressor connected to the grinding chamber of the grinding assembly 12 to supply high-pressure gas into the grinding chamber. At the same time, start the negative pressure mechanism 56 of the cyclone separator to collect the remaining sample in the grinding chamber through the cyclone separator 532 of the second receiving mechanism 5 for the second sample collection. When the rated time is reached, turn off the high-pressure compressed air compressor and the negative pressure mechanism 56 of the cyclone separator to stop grinding.

[0084] Sample bottle removal: The lifting power device 2 55 of the second receiving mechanism 5 drives the bottle placement assembly 2 51 to descend, so that the inlet of the feed pipe 536 of the cyclone separator 532 is separated from the lower outlet of the grinding mechanism 1. When the cyclone separator 532 stops descending, the bottle placement assembly 2 51 descends further, so that the sample bottle on the bottle placement assembly 2 51 is separated from the outlet of the cyclone separator 532. The transfer bottle mechanism 3 takes out the sample bottle and transports it to the bottle receiving mechanism 2.

[0085] The cyclone separator 532 of the second receiving mechanism 5 rotates, causing the feed pipe 536 of the cyclone separator 532 to disengage from the lower outlet of the grinding mechanism 1.

[0086] The above description is illustrative only and not restrictive of the present invention. The present invention aims to provide a sample grinding and powder preparation receiving device and method, which realizes secondary sample receiving through two sample receiving mechanisms, thereby reducing the sample loss rate, increasing the recovery rate to 98-99%, and reducing the loss rate to below 2%. Those skilled in the art will understand that many modifications, variations, or equivalents can be made without departing from the spirit and scope defined by the claims, such as changing the bottle receiving mechanism, changing the sample bottle transfer mechanism, etc., but all of these will fall within the protection scope of the present invention.
