[0002] Currently, in coal-using operations such as generators, a certain amount of coal needs to be collected for analysis before it is fed into the furnace. Usually, a sample is taken out by a sampling machine or manually, then crushed and mixed, and then manually collected into a sampling bucket and taken to the testing room. The whole process involves a lot of manual labor, which is time-consuming and labor-intensive. Moreover, the coal sample is basically exposed to the elements, and after a long period of work, the moisture in the coal sample is easily evaporated, affecting the test results. It is also very easy for staff to add other substances to the coal sample. Summary of the Invention

There are two guide rails 402a, which are two concentric circular guide rails 402a. Each guide rail 402a is provided with four sets of sliders 402b. Each set of sliders 402b has two sliders, and the sliders 402b are connected to each other so as to move synchronously. One of the sliders 402b is provided with a drive motor 402c. The drive motor 402c controls the drive wheel 402d to rotate. The drive wheel 402d is adapted to or meshes with the inner wall of the guide rail 402a, and drives the slider 402b to move through the drive wheel 402d.

[0035] Furthermore, the feeding component 403 includes a feeding port 403a opened on the mounting box 401a and a feeding slide plate 403b disposed at the feeding port 403a. The feeding port 403a is disposed on the lower surface of the mounting box 401a, and the feeding slide plate 403b has an arc-shaped plate structure. A collection box is provided at the bottom of the feeding slide plate 403b, and the sealed packaging bag falls into the collection box along the feeding slide plate 403b.

The fixing plate 501a is a "U"-shaped plate structure disposed on the lower surface of the slider 402b. The fixing groove 501b is disposed on the horizontal side of the fixing plate 501a, and the fixing shaft 501c is disposed on the vertical side of the fixing plate 501a. The fixing grooves 501b on the two sliders 402b face the same direction.

[0037] Furthermore, the active component 502 includes a rotating rod 502a disposed on a fixed shaft 501c, a connecting plate 502b disposed on the rotating rod 502a, a clamping protrusion 502c disposed on the connecting plate 502b, and an extension plate 502d disposed on the rotating rod 502a. The rotating rod 502a is rotatably connected to the fixed shaft 501c. There is a certain angle between the connecting plate 502b and the fixed plate 501a. The clamping protrusion 502c is adapted to the fixed groove 501b. The extension plate 502d extends one end of the length along the connecting plate 502b. After the clamping protrusion 502c is inserted into the fixed groove 501b, it can clamp the opening of the plastic packaging bag.

[0038] Furthermore, the power assembly 503 includes a power cylinder 503a mounted on the slider 402b, a movable rod 503b mounted on the output end of the power cylinder 503a, and a transmission plate 503c mounted on the connecting plate 502b. The power cylinder 503a can control the extension and retraction of the movable rod 503b. The movable rod 503b is fixedly connected to the transmission plate 503c, and the transmission plate 503c is fixedly connected to the extension plate 502d. When the movable rod 503b extends and retracts, it drives the connecting plate 502b to rotate, thereby controlling the clamping and releasing between the clamping protrusion 502c and the fixing groove 501b. The fixing assembly 501, the movable assembly 502, and the power assembly 503 are all located below the slider 402b. The upper surface of the guide rail 402a is fixed to the inner upper surface of the mounting box 401a. The slider 402b is clamped on the guide rail 402a and slides along the guide rail 402a.

The fixed sealing head 504a and the movable sealing head 504b are disposed below the fixed assembly 501 and the movable assembly 502. The fixed sealing head 504a is fixedly installed on the inner wall of the mounting housing 401a. The fixed sealing head 504a and the movable sealing head 504b are disposed at the position where the coal sample is collected in the plastic packaging bag. When the coal sample is collected in the plastic packaging bag, it is directly sealed. The movable sealing head 504b and the electric push rod 504c are installed inside the mounting housing 401a. All the devices in this device are electrically connected to the control box 401d, and are powered and controlled by the control box 401d.

[0040] The rest of the structure is the same as in Example 1.

[0041] Operating Procedure: When using this device, install it below the quantitative packaging device. First, open the feeding door 401c. Place plastic bags under each slider 402b. Activate the power cylinder 503a to control the clamping protrusion 502c to disengage from the fixing groove 501b. At this time, place the opening of the plastic bag in the fixing groove 501b. Activate the power cylinder 503a again to control the clamping protrusion 502c to insert into the fixing groove 501b, thereby clamping the opening of the plastic bag. This fixes the bag and opens it. After the upper component dispenses the material, a fixed weight of coal sample is discharged into this device. After the coal sample enters the device, it falls directly into the plastic bag. When all the coal sample is in the bag, the electric push rod 504c pushes out the movable sealing head 504b until the movable sealing head 504b and the fixed sealing head 502b are closed. 04a together seals the plastic packaging bag. After sealing, the power cylinder 503a is activated again to release the plastic packaging bag. The packaged plastic packaging bag falls directly through the feeding port 403a onto the feeding slide plate 403b and slides out of the device. The staff can then obtain a packaged fixed-weight coal sample, and the moisture of the coal sample is locked inside. The device can also be equipped with a coding or labeling device, connected to the quantitative dispensing device. During sealing, various information such as the weight and collection time of the coal sample can be directly written on the packaging bag. The device is equipped with four sets of moving components 402, which can fit four plastic packaging bags at a time. There are two coal sample collection ports, which can collect two coal samples at the same time. After collection, the slider 402b can move 90° clockwise or counterclockwise to immediately collect the next two coal samples. Example

[0042] Reference Figures 1-3This is the third embodiment of the present invention, which differs from the previous embodiments in that it further includes a supporting component 100, comprising a housing component 101 disposed on the supporting component 401, an electronic scale 102 disposed within the housing component 101, a feed inlet 103 disposed on the housing component 101, and a discharge outlet 104 disposed on both sides of the housing component 101; a distributing component 200, comprising a distributing component 201 disposed within the housing component 101, a receiving component 202 disposed below the distributing component 201, and a control component 203 disposed between the distributing component 201 and the receiving component 202; and a discharging component 300, comprising a discharging component 301 disposed on the housing component 101, a limiting hook 301b disposed within the housing component 101, and a guide component 302 disposed on the receiving component 202.

[0043] Specifically, the housing assembly 101 is equipped with an electronic scale 102, which is used to weigh the receiving assembly 202. The inlet 103 is connected to the discharge of the external sampler. The coal sample after being crushed and mixed by the sampler is fed in through the inlet 103. After being weighed, the coal sample is discharged through the outlet 104. The distribution assembly 201 is used to guide the coal sample into the receiving assembly 202. The control assembly 203 controls the movement of the distribution assembly 201 and drives the receiving assembly 202 to move. The discharge assembly 301 is used to guide and collect the coal sample discharged by the receiving assembly 202. The guide assembly 302 guides the coal sample into the discharge assembly 301 to prevent the coal sample from spilling.

[0044] Furthermore, the housing assembly 101 includes a mounting housing 101a, an arcuate cavity 101b disposed on the mounting housing 101a, and a converging ramp 101c disposed below the mounting housing 101a. The arcuate cavity 101b is disposed on the top of the mounting housing 101a. When the distributing plate 201b of the distributing assembly 201 rotates, both ends of the distributing plate 201b enter the arcuate cavity 101b to prevent the distributing plate 201b from being unable to rotate. The converging ramp 101c does not affect the rotation of the receiving plate 202b of the receiving assembly 202, and at the same time can restrict the position of the telescopic member 302b during the descent and rise of the hopper 202c-3, so that the hopper 202c-3 remains facing upward to the left.

[0045] Furthermore, the material distribution assembly 201 includes an active roller 201a disposed on the mounting housing 101a and a material distribution plate 201b disposed on the active roller 201a; wherein, the material distribution plate 201b includes a main plate 201b-1 fixedly connected to the active roller 201a and a baffle plate 201b-2 disposed on the main plate 201b-1, the active roller 201a is rotatably connected to the mounting housing 101a, the material distribution plate 201b is fixedly connected to the active roller 201a, and the baffle plate 201b-2 is disposed perpendicular to the active roller 201a to prevent coal samples from falling from both sides of the main plate 201b-1.

[0046] Furthermore, the receiving assembly 202 includes a driven roller 202a disposed on the mounting housing 101a, a receiving plate 202b disposed on the driven roller 202a, and a receiving component 202c disposed on the receiving plate 202b. The driven roller 202a is rotatably connected to the mounting housing 101a, and the axes of the driven roller 202a and the driving roller 201a are parallel to each other. The receiving component 202c is disposed at both ends of the receiving plate 202b, and the receiving component 202c is positioned below both ends of the distributing plate 201b. When the coal sample slides down from both ends of the distributing plate 201b, it can fall directly into the receiving component 202c.

[0047] Furthermore, the receiving component 202c includes a column 202c-1 mounted on the receiving plate 202b, a lifting sling 202c-2 mounted on the column 202c-1, and a hopper 202c-3 mounted on the lifting sling 202c-2; wherein, the hopper 202c-3 is a trapezoidal box, and a retaining slope 202c-3a is provided inside the hopper 202c-3, with a discharge port 202c-3b opened at the top of the retaining slope 202c-3a; the receiving plate 202b is an "I"-shaped plate structure, and the columns 202c-1 are located at the four ends of the receiving plate 202b. The column 202c-1 is hoisted to the hopper 202c-3 by the sling 202c-2. The discharge port 202c-3b of the hopper 202c-3 corresponds to the discharge assembly 301. The center of the hopper 202c-3 is located at the bottom of the retaining slope 202c-3a, so that the top opening of the hopper 202c-3 can be aligned with the end of the distribution plate 201b when no coal sample is collected. Since the hopper 202c-3 and the column 202c-1 are connected by the sling 202c-2, it is a flexible connection. Therefore, the hopper 202c-3 can change its angle to prevent spillage after coal sample collection.

[0048] Furthermore, the control component 203 includes a servo motor 203a disposed outside the mounting housing 101a, a transmission component 203b disposed on the driving roller 201a and the driven roller 202a, and a limiting baffle 203c disposed on the inner wall of the mounting housing 101a; wherein, the servo motor 203a is connected to the driving roller 201a for transmission, and the transmission component 203b includes a drive sprocket 203b-1 disposed on the driving roller 201a and a driven sprocket 203b disposed on the driven roller 202a. -2 and the transmission chain 203b-3 connected to the drive sprocket 203b-1 and the driven sprocket 203b-2. The servo motor 203a drives the active roller 201a to rotate. The active roller 201a drives the driven roller 202a to rotate synchronously through the transmission chain 203b-3, so that the material distribution plate 201b and the material receiving plate 202b rotate at the same time and the material distribution plate 201b and the material receiving plate 202b remain parallel. When the material distribution plate 201b rotates, the upper end enters the arc cavity 101b.

[0049] Operating Procedure: During use, install this device at the discharge point of the sampler. The inlet 103 is connected to the sampler. Start the servo motor 203a to control the rotation of the drive roller 201a. The drive roller 201a drives the driven roller 202a to rotate synchronously via the transmission chain 203b-3, causing the distribution plate 201b and the receiving plate 202b to begin rotating until the distribution plate 201b contacts the limit baffle 203c. The limit baffle 203c has inclined surfaces at both ends to control the rotation position of the distribution plate 201b. At this time, the weight of the hopper 202c-3 rests entirely on the electronic scale 102. After the electronic scale 102 weighs the hopper 202c-3, it opens the discharge point of the sampler. The coal sample falls from the inlet 103 onto the distribution plate 201b and then slides down the distribution plate 201b into the hopper 202. Inside c-3, as the amount of coal sample in hopper 202c-3 increases, the reading of electronic scale 102 increases until it reaches the preset value. At this time, electronic scale 102 sends an electrical signal, and the discharge port of the sampler is closed. After a period of time, servo motor 203a starts again, controlling the active roller 201a to rotate in the opposite direction, causing the distribution plate 201b to tilt to the other end. During the movement of distribution plate 201b, hopper 202c-3 discharges the coal sample into the discharge assembly 301 until the distribution plate 201b contacts the limit baffle 203c again. At this time, all the coal sample in the first hopper 202c-3 is discharged, and the other hopper 202c-3 is completely placed on electronic scale 102. The discharge port of the sampler is opened again, and the above process is repeated to weigh each sample. Different sampling weights can be set.

[0050] The discharge assembly 301 includes a discharge bin 301a disposed outside the mounting housing 101a and a limiting hook 301b disposed on the inner wall of the mounting housing 101a; wherein, the discharge bin 301a includes a connection port corresponding to the discharge port 202c-3b, an arc-shaped release space disposed at the top of the discharge bin 301a, a collection chamber disposed at the bottom of the discharge bin 301a and a discharge port disposed at the bottom of the collection chamber.

[0051] Specifically, the discharge bin 301a is used to collect coal samples discharged from the hopper 202c-3. The limiting hook 301b hooks one end of the hopper 202c-3 just before it rises to its highest point, preventing the side of the hopper 202c-3 from rising further, thus causing the hopper 202c-3 to rotate. The rotation axis is the position where the hook hooks the hopper 202c-3. Since the hopper 202c-3 is connected by a flexible sling 202c-2, the two slings 202c-2 connecting the hopper 202c-3 deform at this time, and the coal sample enters the discharge bin 301a from the discharge port 202c-3b of the hopper 202c-3 through the connection port of the discharge bin 301a.

[0052] Furthermore, the guiding component 302 includes a guiding pipe 302a disposed at the discharge port 202c-3b, and a telescopic component 302b disposed on the guiding pipe 302a; wherein, the telescopic component 302b includes a limiting plate disposed at the opening of the guiding pipe 302a, a sleeve disposed on the outer wall of the guiding pipe 302a, and a limiting groove disposed on the sleeve. The guiding pipe 302a is disposed at the discharge port 202c-3b. When the hopper is not loaded with coal samples, the guiding pipe 302a points diagonally upward. The guiding pipe 302a will not touch the inner wall of the mounting housing 101a and the closing slope 101c when the hopper 202c-3 is raised and lowered. When the hopper 202c-3 is about to reach the limiting hook 301b, the guiding pipe 302a touches the limiting hook 301b first, and the guiding pipe 302a is limited by the hook. When hook 301b contacts the hopper 202c-3, the hopper begins to tilt until it contacts the limiting hook 301b. At this point, guide tube 302a points diagonally downwards, and its end extends into the arc-shaped release space. As the hopper 202c-3 tilts, the sleeves of telescopic component 302b begin to slide out under gravity until the limiting grooves of each sleeve press against the limiting plates. During the sliding process, telescopic component 302b is in the arc-shaped release space, which does not obstruct the extension of telescopic component 302b. When the hopper 202c-3 descends, guide tube 302a is stuck at the connection port, and due to the weight of the hopper 202c-3, guide tube 302a points diagonally upwards again, and all sleeves retract under gravity.

[0053] Furthermore, the limiting hook 301b is adapted to the hopper 202c-3. The limiting hook 301b is set on the moving path of the hopper 202c-3. The center of gravity of the hopper 202c-3 is located at the bottom of the retaining slope 202c-3a. The telescopic component 302b is adapted to the arc-shaped release space.

[0054] Operating Procedure: During use, as hopper 202c-3 rises, hopper 202c-3 and guide pipe 302a are restricted by limiting hook 301b, causing guide pipe 302a to begin to level and hopper 202c-3 to begin to tilt. At this time, due to the retaining slope 202c-3a, coal sample will not be discharged from hopper 202c-3. As hopper 202c-3 continues to rise, it is hooked by limiting hook 301b, and telescopic component 302b begins to point diagonally downwards. Under the action of gravity, each sleeve extends into the discharge bin. Within the arc-shaped release space of 301a, the coal sample in hopper 202c-3 enters guide pipe 302a through discharge port 202c-3b and then enters telescopic component 302b to be discharged into discharge bin 301a. When hopper 202c-3 descends, guide pipe 302a is stuck at the connection port, and due to the weight of hopper 202c-3, guide pipe 302a points diagonally upward again. All sleeves retract under the action of gravity. After the coal sample enters discharge bin 301a, it gathers together in the collection chamber and is discharged from the discharge port. At this time, the coal sample can be collected from the discharge port.
