Description

Technical Field

[0001] The present invention relates to the technical field of coal quality detection, and in particular to a two-in-one feeding system. Background Art

[0002] Traditional coal quality testing methods are time-consuming and labor-intensive and cannot meet the needs of the rapid development of the coal industry. Therefore, various coal quality rapid testing technologies have emerged.

[0003] To accommodate the coal quality rapid test analyzer, a detection belt conveyor is typically added to the feeder conveyor of the traditional sampling machine. Coal samples are then transferred from the feeder conveyor to the detection belt conveyor via a transmission pipeline. This results in a large number of components, a larger space occupied by the feeding system, and high manufacturing costs. Furthermore, due to structural limitations, the entire feeding system must be suspended if the coal quality rapid tester malfunctions, affecting its overall efficiency. This presents a problem that needs to be addressed. Summary of the Invention

To this end, one object of the present invention is to provide a two-in-one feeding system that occupies less space as a whole and, in the event of a malfunction of the coal quality rapid testing instrument, can automatically control the belt transmission mechanism to transfer samples to a sample collection bucket for collection, thereby preserving the samples in a timely manner without suspending the entire two-in-one feeding system, thereby improving the operating efficiency of the two-in-one feeding system.

The belt transmission mechanism is a forward and reverse bidirectional transmission mechanism, and the belt transmission mechanism includes a first transmission end and a second transmission end. The first transmission end and the second transmission end are located at the two ends of the belt transmission mechanism along the transmission direction of the belt transmission mechanism.

In addition, by providing a device in the first transmission pipeline for detecting the accumulation of samples in the pipeline, The height detection part is configured to detect the height of the sample, and when the sample stacking height in the first transmission pipe is greater than the first preset stacking height, the controller controls the belt transmission mechanism to transport the sample to the sample collecting barrel, so that it can judge whether the coal quality rapid test instrument is working normally in a relatively timely and accurate manner, and when the coal quality rapid test instrument fails, the controller can automatically control the belt transmission mechanism to transmit the sample to the sample collecting barrel, so that the sample collecting barrel can collect the sample in time, and the sample in the sample collecting barrel can be directly used for manual sampling, such as manual testing, to reduce or avoid sample waste without pausing the entire two-in-one feeding system, which is beneficial to improving the working efficiency of the two-in-one feeding system.

[0026] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] Reference below Figure 1 A two-in-one feeding system 100 according to an embodiment of the present invention is described.

[0028] Reference Figure 1 According to an embodiment of the present invention, a two-in-one feeding system 100 includes a coal quality rapid tester 1, a sample collecting bucket 2, a transmission component 3, a detection element 41 and a controller. The coal quality rapid tester 1 is used to test samples, the sample collecting bucket 2 is used to collect samples, and the samples collected by the sample collecting bucket 2 are used for manual sampling. The transmission component 3 is used to transmit samples and the transmission component 3 includes a belt transmission mechanism 31, a first transmission pipe 32 and a second transmission pipe 33. The belt transmission mechanism 31 is a forward and reverse bidirectional transmission mechanism. The belt transmission mechanism 31 includes a first transmission end 311 and a second transmission end 312. The first transmission end 311 and the second transmission end 312 are located at the two ends of the belt transmission mechanism 31 along the transmission direction of the belt transmission mechanism 31. The first transmission pipe 32 is arranged between the first transmission end 311 and the coal quality rapid tester 1, and the second transmission pipe 33 is arranged between the second transmission end 312 and the sample collecting bucket 2. The belt transmission mechanism 31 is used to transmit the sample to the coal quality rapid tester 1 through the first transmission pipe 32 and to transmit the sample to the sample collecting bucket 2 through the second transmission pipe 33.

[0029] The transmission component 3 adopts a forward and reverse bidirectional belt transmission mechanism 31 to transmit samples. The first transmission end 311 of the belt transmission mechanism 31 is connected to the coal quality rapid tester 1 through a first transmission pipe 32, and the second transmission pipe 33 is connected to the second transmission end 312 of the belt transmission mechanism 31 and the sample collecting bucket 2. In this way, only a single belt transmission mechanism 31 is set to realize the process of transmitting samples to the coal quality rapid tester 1 or the sample collecting bucket 2 respectively. Compared with using two belt transmission mechanisms 31 to transmit samples to the coal quality rapid tester 1 and the sample collecting bucket 2 respectively, the belt transmission mechanism 31 is a forward and reverse bidirectional belt transmission mechanism 31, which can reduce the number of belt transmission mechanisms 31 and the number of parts accordingly. For example, there is no need to set up two sets of driving mechanisms, etc., which reduces the space occupied by the two-in-one feeding system 100 as a whole, and is also conducive to reducing manufacturing costs.

[0030] A detection member 41 is provided in the first transmission pipe 32 and is used to detect the sample accumulation height within the first transmission pipe 32 to determine whether the coal quality rapid tester 1 is functioning properly. The detection member 41 and the belt transmission mechanism 31 are both electrically connected to a controller. The controller is used to control the belt transmission mechanism 31 to transport the sample to the sample collection bucket 2 when the sample accumulation height within the first transmission pipe 32 exceeds a first preset accumulation height. By detecting the sample accumulation height within the first transmission pipe 32, the detection member 41 can more accurately determine whether the coal quality rapid tester 1 is functioning properly. For example, if the coal quality rapid tester 1 can perform sample testing normally, the sample within the first transmission pipe 32 will be continuously consumed and will not accumulate. If the sample accumulation height within the first transmission pipe 32 exceeds the first preset accumulation height, it indicates that the coal quality rapid tester 1 may have a fault and require maintenance, resulting in the sample within the first transmission pipe 32 not being promptly transported to the coal quality rapid tester 1, causing the sample accumulation height within the first transmission pipe 32 to exceed the first preset accumulation height.

[0031] When the sample stacking height in the first transmission pipe 32 is greater than the first preset stacking height, the controller automatically controls the belt transmission mechanism 31 to run in the other direction to transmit the sample to the sample collecting barrel 2 through the second transmission pipe 33, so that the sample collecting barrel 2 can collect the sample in time, and the sample in the sample collecting barrel 2 can be directly used for manual sampling, such as manual testing, to avoid sample waste. In addition, the sample collecting barrel 2 can also serve as a temporary storage for samples. After the maintenance of the coal quality rapid tester 1 is completed, the samples stored in the sample collecting barrel 2 can be retransmitted to the coal quality rapid tester 1 for testing without pausing the entire two-in-one feeding system 100, which is beneficial to improving the working efficiency of the two-in-one feeding system 100.

[0032] According to the two-in-one feeding system 100 of the embodiment of the present invention, the forward and reverse bidirectional belt transmission mechanism 31 is used to transmit samples through the transmission component 3, and the first transmission pipe 32 is connected with the belt transmission mechanism 31 and the coal quality rapid detection instrument 1, and the second transmission pipe 33 is connected with the belt transmission mechanism 31 and the sample collecting bucket 2. In this way, only a single belt transmission mechanism 31 is provided to realize the process of transmitting samples to the coal quality rapid detection instrument 1 or the sample collecting bucket 2 respectively, which can reduce the number of parts. For example, there is no need to set up two sets of additional drive mechanisms, etc., which reduces the space occupied by the two-in-one feeding system 100 as a whole and is also conducive to reducing manufacturing costs. In addition, by providing a device for detecting the sample in the first transmission pipe 32, The detection part 41 of the sample stacking height is configured, and when the sample stacking height in the first transmission pipe 32 is greater than the first preset stacking height, the controller controls the belt transmission mechanism 31 to transport the sample to the sample collecting barrel 2, so that it can be judged more timely and accurately whether the coal quality rapid tester 1 is working normally, and when the coal quality rapid tester 1 fails, the controller can automatically control the belt transmission mechanism 31 to transport the sample to the sample collecting barrel 2, so that the sample collecting barrel 2 can collect the sample in time, and the sample in the sample collecting barrel 2 can be directly used for manual sampling, such as manual testing, reducing or avoiding sample waste without pausing the entire two-in-one feeding system 100, which is beneficial to improving the working efficiency of the two-in-one feeding system 100.

[0033] Reference Figure 1 According to some embodiments of the present invention, the transmission component 3 includes a cover shell 34, which is arranged on the outside of the belt transmission mechanism 31. A feed port 341 is formed on the cover shell 34. The feed port 341 is located directly above the belt transmission mechanism 31 and the feed port 341 is located between the first transmission end 311 and the second transmission end 312. A first discharge port 342 and a second discharge port 343 are formed on the cover shell 34. The first transmission pipe 32 is connected to the first discharge port 342, and the second transmission pipe 33 is connected to the second discharge port 343.

[0034] The cover 34 is arranged on the outside of the belt transmission mechanism 31, so that the outer surface of the belt transmission mechanism 31 forms a relatively closed transmission space, which can effectively prevent the sample from falling directly to the outside of the feeding system due to vibration, inertia, etc. during the transmission process on the belt transmission mechanism 31. The cover 34 can also protect the sample and block external dust, impurities, etc. from entering the transmission path of the sample, avoiding sample contamination, and improving the accuracy of the subsequent coal quality rapid test instrument 1 and the purity of the manually tested samples in the sample collection barrel 2.

[0035] A feed port 341 is formed on the cover shell 34, which allows samples to enter the belt transmission mechanism 31 from a preset position to facilitate transmission of the samples. The feed port 341 is located directly above the belt transmission mechanism 31 and between the first transmission end 311 and the second transmission end 312, so that the sample can fall directly into the belt transmission mechanism 31 under the action of its own gravity. There is no need to use a feed guide device to guide the sample into the belt transmission mechanism 31, thereby reducing the number of parts.

[0036] The feed port 341 is located between the first transmission end 311 and the second transmission end 312, and can also cooperate with the forward and reverse functions of the belt transmission mechanism 31. For example, when the belt transmission mechanism 31 runs forward, the sample falls into the belt transmission mechanism 31 from the feed port 341 and moves toward the first transmission end 311, and enters the coal quality rapid tester 1 through the first discharge port 342. When the belt transmission mechanism 31 runs reversely, it moves to the second transmission end 312, and enters the sample collecting barrel 2 through the second discharge port 343. It can adapt to the two-way transmission requirements without adjusting the feed position, further simplifying the operation logic.

[0037] In addition, the feed port 341, the first discharge port 342 and the second discharge port 343 are formed on the cover shell 34, and the belt transmission mechanism 31, the feed port 341, the first discharge port 342 and the second discharge port 343 can be partially integrated into a whole through the cover shell 34, so that these components can be arranged more centrally, which can make the overall structure of the two-in-one feeding system 100 more compact and further reduce the space occupied by the two-in-one feeding system 100 as a whole.

[0038] Reference Figure 1 According to some embodiments of the present invention, the belt transmission mechanism 31 is two belt transmission mechanisms arranged along the first direction. The first direction (for example, refer to Figure 1 The e1 direction in the figure is parallel to the conveying direction of the belt transmission mechanism 31. The sample collecting barrel 2 and the coal quality rapid tester 1 are located on the same side of the width direction of the belt transmission mechanism 31. There are two sample collecting barrels 2, and the two sample collecting barrels 2 are located on both sides of the coal quality rapid tester 1 along the first direction. The outer side of each belt transmission mechanism 31 is covered with a cover 34. The two belt transmission mechanisms 31 are arranged along the first direction to form a parallel transmission channel, which can simultaneously receive samples from two sources. Compared with a single belt transmission mechanism 31, the sample transmission volume can be doubled in the same time, thereby improving the transmission efficiency of the belt transmission mechanism 31. Moreover, by sharing one coal quality rapid tester 1 with two belt transmission mechanisms 31, the process of a single coal quality rapid tester 1 detecting samples transmitted by two belt transmission mechanisms 31 can be realized, thereby improving the use efficiency of the coal quality rapid tester 1 and effectively reducing the number of components used, thereby effectively reducing the space occupied by the two-in-one feeding system 100 as a whole and reducing manufacturing costs.

[0039] By locating the sample collecting bucket 2 and the coal quality rapid tester 1 on the same side of the belt transmission mechanism 31 in the width direction, the layout can be made more centralized and compact, avoiding the waste of space caused by the sample collecting bucket 2 and the coal quality rapid tester 1 being dispersed on both sides of the belt transmission mechanism 31 in the width direction.

[0040] In addition, a cover 34 is provided on the outside of each belt transmission mechanism 31, which can protect the samples on the two belt transmission mechanisms 31 and prevent the samples on the two belt transmission mechanisms 31 from being mixed with external impurities, thereby ensuring the accuracy of subsequent detection or the purity of the collected samples.

[0041] Reference Figure 1 According to some embodiments of the present invention, two belt transmission mechanisms 31 share a first transmission pipeline 32. The first transmission pipeline 32 includes a main transmission pipeline 321 and two branch transmission pipelines 322. The two branch transmission pipelines 322 are respectively connected to the discharge ports of the cover shells 34 corresponding to the two belt transmission mechanisms 31. The main transmission pipeline 321 is connected to the side of the two branch transmission pipelines 322 away from the discharge ports, and the main transmission pipeline 321 is located between the branch transmission pipelines 322 and the coal quality rapid test instrument 1. The detection component 41 is arranged on the main transmission pipeline 321.

[0042] The design of the two belt transmission mechanisms 31 converging into the main transmission pipeline 321 through two transmission branch pipelines 322 allows the two belt transmission mechanisms 31 to share the first transmission pipeline 32. Compared with each belt transmission mechanism 31 being provided with a corresponding first transmission pipeline 32 to transmit the sample to the coal quality rapid tester 1, this reduces the material of a set of first transmission pipelines 32 and reduces the manufacturing cost of the transmission component 3; and the main transmission pipeline 321 after the two transmission branch pipelines 322 converge only needs to be connected to the coal quality rapid tester 1 once, reducing the number of interfaces between the first transmission pipeline 32 and the coal quality rapid tester 1, simplifying the installation process and improving assembly efficiency.

[0043] By providing the detection component 41 in the main conveying pipe 321 and detecting the sample accumulation height in the main pipe through the detection component 41, it is possible to directly and accurately judge whether the coal quality rapid tester 1 is operating normally. If the sample accumulation height in the main conveying pipe 321 is greater than the first preset accumulation height, it indicates that the coal quality rapid tester 1 cannot process the sample entering from the main conveying pipe 321 in time, which makes it easier for the controller to control the belt transmission mechanism 31 to transport the sample to the sample collecting barrel 2 in a more timely and accurate manner. In this way, there is no need to separately detect the sample accumulation height in the two conveying branch pipes 322, which reduces the number of detection components 41, and the controller only needs to process the detection signal of one detection component 41 to determine whether the coal quality rapid tester 1 is operating normally, thereby simplifying the logic of the control program.

[0044] For example, when the detection part 41 detects that the sample accumulation height in the conveying main pipeline 321 is greater than the first preset accumulation height, the controller can simultaneously control the two belt transmission mechanisms 31 to transfer the sample to the sample collecting barrel 2, so as to prevent one of the belt transmission mechanisms 31 from continuing to transport the sample into the conveying main pipeline 321, causing the accumulation height to continue to increase, and prevent the conveying main pipeline 321 from being aggravated by the continuous sample supply on one side.

[0045] Reference Figure 1 According to some embodiments of the present invention, the belt transmission mechanism 31 is provided with a first sensor, which is used to detect the current transmission direction of the belt transmission mechanism 31. The first sensor is electrically connected to the controller. A first signal light 346 and a second signal light 347 are provided on the outside of the cover 34. The first signal light 346 and the second signal light 347 are both electrically connected to the controller. The first signal light 346 is located directly above the first transmission end 311, and the second signal light 347 is located directly above the second transmission end 312. The controller is used to control the opening or closing of the first signal light 346 or the second signal light 347 according to the current transmission direction of the belt transmission mechanism 31.

[0046] The controller is electrically connected to the first sensor, and the first signal light 346 and the second signal light 347 are both electrically connected to the controller, so that the controller can automatically switch the state of the first signal light 346 or the second signal light 347 according to the current transmission direction of the belt transmission mechanism 31 detected by the first sensor, thereby reducing the state misjudgment caused by manual operation (such as forgetting to switch the state of the signal light) and ensuring the consistency of the state of the signal light with the actual transmission direction.

[0047] The first signal light 346 is located directly above the first transmission end 311, the second signal light 347 is located directly above the second transmission end 312, and the first signal light 346 and the second signal light 347 are both arranged on the outside of the cover 34. The current transmission direction of the belt transmission mechanism 31 is intuitively reflected through light signals. This allows the operator outside the cover 34 to know the current transmission direction of the belt transmission mechanism 31 more directly and accurately based on the status of the signal light. For example, when the first signal light 346 is on, it indicates that the current transmission direction of the belt transmission mechanism 31 is to transmit the sample to the coal quality rapid tester 1. When the second signal light 347 is on, it indicates that the current transmission direction of the belt transmission mechanism 31 is to transmit the sample to the sample collecting bucket 2.

[0048] Reference Figure 1According to some embodiments of the present invention, a cleaning mechanism 344 is provided within the housing 34. The cleaning mechanism 344 is located below the belt transmission mechanism 31 and is used to clean the belt of the belt transmission mechanism 31. By cleaning the belt of the belt transmission mechanism 31 with the cleaning mechanism 344, residual sample on the belt surface can be promptly removed, effectively reducing the amount of sample remaining on the belt surface. For example, this can reduce the possibility of cross-contamination between different batches of samples and improve the purity of each batch of samples.

[0049] For example, when the belt transmission mechanism 31 is transporting samples, for example, the samples are powdered or granular coal ash, samples are likely to remain on the belt surface. If they are not cleaned in time, when the belt transmission mechanism 31 transports the next batch of samples, these residual samples may be mixed into the next batch of samples, resulting in cross-contamination of samples from different batches, affecting the accuracy of subsequent testing. By cleaning the belt of the belt transmission mechanism 31 through the cleaning mechanism 344, the residual samples on the belt surface can be removed in time, reducing the possibility of cross-contamination of samples from different batches, thereby improving the accuracy of subsequent sample testing.

[0050] In addition, by locating the cleaning mechanism 344 below the belt transmission mechanism 31, the space in the upper and lower directions of the belt transmission mechanism 31 can be fully utilized to avoid interference between the cleaning mechanism 344 and the samples located above the belt transmission mechanism 31. The samples remaining on the belt can also be cleared in time, making the overall structure of the cleaning mechanism 344 and the belt transmission mechanism 31 more compact.

[0051] Reference Figure 1 According to some embodiments of the present invention, the cleaning mechanism 344 includes a roller brush and a roller brush drive mechanism. The roller brush drive mechanism is connected to the roller brush to drive the roller brush to rotate, so that the roller brush contacts the belt. The roller brush and the belt are in flexible contact, for example, by elastically deforming the bristles of the roller brush to conform to the belt surface. Compared to a rigid scraper, the elastic deformation of the roller brush bristles allows the roller brush to promptly remove residual samples from the belt surface while preventing the roller brush from causing scratches, tears, and other wear on the belt surface.

[0052] Reference Figure 1According to some embodiments of the present invention, a portion of the cover 34 is recessed downward to form an ash collection trough 345. The roller brush is located within the ash collection trough 345. The ash collection trough 345 has an ash discharge port, which is equipped with an ash discharge valve for opening and closing the ash discharge port. The ash collection trough 345 can collect and store this residue. Residue removed from the belt surface by the roller brush can fall directly into the ash collection trough 345 below. Compared to the absence of the ash collection trough 345, where the residue is scattered to any position at the bottom of the cover 34, the recessed portion of the cover 34 can collect the residue and prevent it from floating or accumulating freely within the cover 34.

[0053] The ash discharge port of the ash collecting trough 345 can facilitate the timely discharge of the residue in the ash collecting trough 345. By controlling the opening or closing of the ash discharge valve, the opening or closing of the ash discharge port is controlled. For example, when the residue accumulation height in the ash collecting trough 345 is relatively high, the ash discharge valve can be controlled to open the ash discharge port so that the residue in the ash collecting trough 345 can be discharged through the ash discharge port in time to avoid the residue in the ash collecting trough 345 from adhering to the belt surface again due to the residue accumulation height in the ash collecting trough 345 being too high. For another example, when the residue accumulation height in the ash collecting trough 345 is lower than the preset accumulation height, the ash discharge valve can be controlled to close the ash discharge port to avoid the residue in the ash collecting trough 345 from being discharged to the outside of the cover shell 34 at will through the ash discharge port.

[0054] Reference Figure 1 According to some embodiments of the present invention, a third sensor 43 is provided on the side wall of the ash collecting trough 345 for detecting the coal ash accumulation height within the ash collecting trough 345. The third sensor 43 is electrically connected to a controller, which is configured to issue an ash discharge reminder when the coal ash accumulation height within the ash collecting trough 345 exceeds a third preset accumulation height. By detecting the coal ash accumulation height within the ash collecting trough 345 by the third sensor 43, intelligent monitoring and early warning of residues within the ash collecting trough 345 can be achieved. Compared to the method of manually opening the cover to check the coal ash accumulation height within the ash collecting trough 345 at regular intervals, this method can avoid coal ash overflow within the ash collecting trough 345 due to excessively long manual inspection cycles, and can more promptly and accurately determine the coal ash information within the ash collecting trough 345 and perform ash discharge operations in a timely manner.

[0055] For example, the controller determines that the coal ash accumulation height in the ash collecting trough 345 is greater than the third preset accumulation height based on the detection information of the third sensor 43, and promptly issues a reminder to discharge the ash, so as to facilitate timely ash discharge operations and effectively avoid secondary pollution to the belt caused by the overflow of coal ash in the ash collecting trough 345.

[0056] Reference Figure 1According to some embodiments of the present invention, the apparatus further includes a transfer mechanism 5 having a groove 51 formed therein. At least a portion of the coal quality rapid tester 1 is accommodated within the groove 51. The first transmission pipe 32 is detachably connected to the coal quality rapid tester 1, and the sample collecting barrel 2 is spaced apart from or separably disposed from the first transmission pipe 32. Accommodating at least a portion of the coal quality rapid tester 1 within the groove 51 may include the following situations: for example, a portion of the coal quality rapid tester 1 may be accommodated within the groove 51; or, for another example, the entire coal quality rapid tester 1 may be accommodated within the groove 51.

[0057] By providing a transfer mechanism 5, the difficulty of moving the coal quality rapid tester 1 can be reduced, making the transfer of the coal quality rapid tester 1 more convenient and labor-saving. For example, when the coal quality rapid tester 1 fails, the transfer mechanism 5 can move the coal quality rapid tester 1 to a larger space more quickly and labor-savingly to facilitate the maintenance of the coal quality rapid tester 1; and by at least partially arranging the coal quality rapid tester 1 in the groove 51 of the transfer mechanism 5, the overall structure of the coal quality rapid tester 1 and the transfer mechanism 5 can be made more compact, and the surrounding wall of the groove 51 can also limit the coal quality rapid tester 1, thereby reducing the relative movement between the coal quality rapid tester 1 and the transfer mechanism 5.

[0058] The first transmission pipe 32 is detachably connected to the coal quality rapid tester 1. In this way, when the coal quality rapid tester 1 fails, the connection between the coal quality rapid tester 1 and the first transmission pipe 32 can be removed to facilitate the maintenance or replacement of the coal quality rapid tester 1, avoiding maintenance operations on the entire two-in-one feeding system 100, thereby reducing the difficulty of maintaining the coal quality rapid tester 1.

[0059] By setting the sample collecting barrel 2 and the first transmission pipe 32 at intervals or detachably, when the sample collecting barrel 2 needs to be moved, it is only necessary to separate the sample collecting barrel 2 from the first transmission pipe 32, and then the sample collecting barrel 2 can be moved alone without moving the entire two-in-one feeding system 100, making the movement of the sample collecting barrel 2 more convenient.
