Description

Technical Field

[0001] The present invention mainly relates to the field of sampling, preparation and analysis equipment for material samples, and particularly relates to a sample mixing and batch - returning system for sample sampling, preparation and analysis. Background Art

[0002] For the sampling, preparation and analysis of material samples (such as ores and coal), each country has mandatory standards, and the sampling, sample preparation and analysis work must be carried out in accordance with the standards. Taking the analysis of coal as an example, the criterion for the sampling, preparation and analysis process is to gradually reduce the particle size of the collected sample and also gradually reduce the mass under the premise of not destroying the representativeness of the sample until it meets the requirements of the particle size and mass (weight) accuracy for laboratory testing of the sample. Then, relevant test analysis is carried out on the sample that meets the requirements. There should be no loss of samples during this process, and no physical or chemical changes should occur to the samples, otherwise it will affect the final test results.

[0003] Currently, there are higher and higher requirements for the integrated sampling and preparation operation and the integrated sampling and preparation system of samples, such as the sample mixing and batch - returning operation. The so - called sample mixing and batch - returning means that at the front end of the sampling and sample preparation operation, multiple batches of different coal samples are prepared and put into sample barrels, and each batch of coal sample barrels also has a certain quantity. And during the production and transportation process, the coal samples will be in chaos. This makes it necessary to first gather and combine these coal samples of different batches, different quantities and disordered order into the same batch at the back end of the sampling and sample preparation operation, and then centrally complete the sampling and sample preparation operation for each same batch.

[0004] For example: Some existing sample mixing and batch - returning systems are equipped with parallel temporary storage transfer lines, sample preparation transfer lines and transfer transfer lines; some are equipped with parallel temporary storage transfer lines, non - current sample transfer lines, empty barrel transfer lines and sample preparation transfer lines; and some are equipped with longitudinally arranged parallel empty barrel conveyor belts, sample preparation conveyor belts and batch - returning circulating conveyor belts. The following technical problems exist:

[0005] First, setting up so many conveyor lines is huge in volume and occupies a large area, which is not suitable for flexible industrial placement and use. Especially if multi - batch sample mixing and batch - returning operations are to be realized, in order to meet the circular batch - returning cycle, the system volume will inevitably become more huge and complex. Second, the function of each transfer line is too single. During the process of sample barrel mixing and batch - returning, the sample barrels need to circulate many times on several conveying mechanisms. The circulating transportation of sample barrels takes a long time, the batch - returning time is long, the batch - returning rhythm is slow, and the work efficiency is low. Third, the number of times of reading and writing cards for sample barrels is large and sorting is difficult. Each time, all the sample barrels storing samples need to be read card by card before the required batch of sample barrels can be selected, resulting in reduced reliability.

[0006] Also, for example, in some existing sample collection, preparation, and homogenization batch combination systems, there is an in-barrel conveyor belt used to directly connect with a transfer cart for transporting sample barrels. After all the sample barrels on the transfer cart are transported to the in-barrel conveyor belt, they are then transported to other conveyor belt devices in the batch combination system through the in-barrel conveyor belt. When empty barrels are discharged, the empty barrels are also transported to the transfer cart through the in-barrel conveyor belt. The following technical problems exist:

[0007] First, since the width of the transfer cart is similar to that of the in-barrel conveyor belt, if the sample barrels are to smoothly enter and exit between the two conveying mechanisms of the transfer cart and the in-barrel conveyor belt, the rear of the cart needs to be aligned with the in-barrel conveyor belt. This requires a high precision in parking the transfer cart. If the parking is inaccurate, multiple reverse maneuvers are needed to align. This places high requirements on vehicle operators, makes docking difficult, consumes a long time, has a low degree of automation, and low work efficiency.

[0008] Second, if they are not aligned, it seriously affects the automatic entry and exit of the sample barrels, not only affecting the sorting and batch combination efficiency of the batch combination, but also possibly causing the sample barrels to fall. And the misalignment makes the position where the sample barrels are transported to the in-barrel conveyor belt inaccurate, thus affecting the precise docking between the in-barrel conveyor belt and other conveyor belt devices in the batch combination system. Summary of the Invention

[0009] The technical problem solved by the present invention is: in view of the problems existing in the prior art, to provide a batch combination system for sample collection, preparation, and homogenization that is simple and compact in structure, small in floor area, high in degree of automation and intelligence, can greatly improve work efficiency, and has high reliability.

[0010] To solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A sample sampling, preparation and analysis sample batch merging system, comprising a control unit, a front-end docking and transmission unit, a rear-end docking and transmission unit, and more than one set of batch merging and conveying units arranged between the front-end docking and transmission unit and the rear-end docking and transmission unit. The front-end docking and transmission unit is used to dock with a transport vehicle, and the rear-end docking and transmission unit is used to dock with a sample preparation device. The batch merging and conveying unit includes a transmission rack, on which a plurality of rollers are provided to form a roller transmission line capable of forward and reverse transmission to transport sample barrels; a plurality of lifting and limiting mechanisms are provided on the transmission rack and can protrude upward from the gaps between adjacent rollers. The plurality of lifting and limiting mechanisms are arranged in two parallel columns along the transmission direction to divide the roller transmission line into a first temporary storage sample transmission channel, a current sample transmission channel, and a second temporary storage sample transmission channel from left to right in sequence when rising. The first temporary storage sample transmission channel and the second temporary storage sample transmission channel are used to temporarily store the sample barrels to be prepared transported by the front-end docking and transmission unit / or temporarily store the empty sample barrels after sample preparation transported by the rear-end docking and transmission unit; a plurality of double-sided hook barrel mechanisms are arranged on the transmission rack along the transmission direction; during operation, under the control instruction of the control unit, the plurality of lifting and limiting mechanisms descend so that the double-sided hook barrel mechanisms can hook the sample barrels of the same batch on the first temporary storage sample transmission channel or the second temporary storage sample transmission channel to the current sample transmission channel, and then the plurality of lifting and limiting mechanisms rise so that the roller transmission line can forwardly transmit the sample barrels of the same batch on the current sample transmission channel to the rear-end docking and transmission unit / or reversely transmit the empty sample barrels of the same batch to the front-end docking and transmission unit.

[0012] As a further improvement of the present invention, the front-end docking and transmission unit includes a horizontal translation mechanism and a longitudinal transmission mechanism provided on the horizontal translation mechanism. A positioning component is provided on the longitudinal transmission mechanism to form a plurality of sample barrel positioning areas on the longitudinal transmission mechanism. A detection switch component for detecting the position of the transport vehicle carriage is also provided on the longitudinal transmission mechanism. During operation, the longitudinal transmission mechanism translates on the horizontal translation mechanism and forms a docking with the carriage through the detection switch component to longitudinally transmit a plurality of sample barrels in the carriage to the sample barrel positioning areas, and then translates to the first temporary storage sample transmission channel and the second temporary storage sample transmission channel through the horizontal translation mechanism to longitudinally transmit the plurality of sample barrels to the first temporary storage sample transmission channel and the second temporary storage sample transmission channel.

[0013] As a further improvement of the present invention, a roller component capable of forward and reverse transmission is provided on the longitudinal transmission mechanism. The positioning component includes two first positioning plates and two second positioning plates. One first positioning plate is provided at each end near the left and right ends of the roller component. The two second positioning plates are arranged in parallel in the middle of the roller component to sandwich and limit the sample barrels in the sample barrel positioning areas formed between the adjacent first positioning plates and the second positioning plates.

[0014] As a further improvement of the present invention, the front and rear ends of the first positioning plate and the second positioning plate are both inclined, and are used to cooperate with the front and rear ends of the adjacent first positioning plate and the second positioning plate to form a flared shape to guide the transmitted sample barrels.

[0015] As a further improvement of the present invention, the positioning assembly further includes a plurality of fixing rods. One end of the fixing rod is fixed on the longitudinal transmission mechanism, and the other end extends upward from the gap between the rollers of the roller assembly to fix the second positioning plate.

[0016] As a further improvement of the present invention, more than two sample barrels can be longitudinally carried in each sample barrel positioning area. A bracket is further provided above the sample barrel positioning area on the longitudinal transmission mechanism. A card reader is provided at the corresponding bearing position of each sample barrel on the bracket to read the information on each sample barrel below and transmit it to the control unit.

[0017] As a further improvement of the present invention, a first barrel blocking mechanism is further provided at the rear end of the longitudinal transmission mechanism in the transmission direction of the roller assembly. The first barrel blocking mechanism includes a first cylinder and a first barrel blocking plate connected to each other. The first cylinder drives the first barrel blocking plate to extend upward from the gap between the rollers to limit the sample barrel on the roller assembly.

[0018] As a further improvement of the present invention, a second barrel blocking mechanism is further provided at the front end of the longitudinal transmission mechanism in the transmission direction of the roller assembly. The second barrel blocking mechanism includes a second cylinder and a second barrel blocking plate connected to each other. The second cylinder drives the second barrel blocking plate to extend upward from the gap between the rollers to limit the sample barrel on the roller assembly.

[0019] As a further improvement of the present invention, the lateral translation mechanism includes a horizontally arranged frame. A slide rail assembly and a lateral driving assembly are provided on the frame. The longitudinal transmission mechanism is slidably and limitedly installed on the slide rail assembly and is used to slide laterally along the slide rail assembly under the drive of the lateral driving assembly.

[0020] As a further improvement of the present invention, a third barrel blocking mechanism that can extend upward from the adjacent roller gap is provided at the transmission rear ends of the first temporary sample transmission channel and the second temporary sample transmission channel on the transmission rack. When the roller transmission line forwards the to-be-made sample barrels of the same batch on the current sample transmission channel out of the sample preparation, the two third barrel blocking mechanisms extend to prevent the sample barrels on the first temporary sample transmission channel and the second temporary sample transmission channel from being forwarded out.

[0021] As a further improvement of the present invention, a third bucket blocking mechanism that can protrude upward from the gap between adjacent rollers is also provided at the front end of the transmission on both the first temporary sample transmission channel and the second temporary sample transmission channel. When the roller transmission line reversely transmits the empty sample buckets of the same batch on the current sample transmission channel, the two third bucket blocking mechanisms protrude to prevent the sample buckets on the first temporary sample transmission channel and the second temporary sample transmission channel from being reversely transmitted.

[0022] As a further improvement of the present invention, a third bucket blocking mechanism that can protrude upward from the gap between adjacent rollers is also provided at the front end and the rear end of the transmission on the current sample transmission channel, so as to limit the transmission of the sample buckets on the current sample transmission channel at the protruding position.

[0023] As a further improvement of the present invention, the lifting limit mechanism includes a mounting seat, a limit guide rail, and a third cylinder arranged below the rollers. The limit guide rail and the third cylinder are vertically fixed on the transmission rack. The mounting seat is simultaneously connected to the limit guide rail and the third cylinder and is used to drive the mounting seat to lift along the limit guide rail through the third cylinder. A plurality of limit frames arranged along the transmission direction are installed on the mounting seat, and each limit frame can protrude upward from the gap between adjacent rollers.

[0024] As a further improvement of the present invention, the double-sided bucket hooking mechanism includes a mounting bracket arranged below the rollers. The mounting bracket is fixed on the transmission rack along the axial direction of the rollers. A limit slide rail and a driving component are arranged along the axial direction on the mounting bracket. A bucket hooking bent plate that protrudes upward from the gap between adjacent rollers is provided at both ends of the mounting bracket, and both bucket hooking bent plates are connected to the limit slide rail and the driving component.

[0025] As a further improvement of the present invention, two position detectors are also provided on the mounting bracket. The position detectors are communicatively connected to the driving component to control the moving stroke of the bucket hooking bent plate.

[0026] As a further improvement of the present invention, the rear-end docking transmission unit includes a rear-end lateral translation mechanism and a rear-end longitudinal transmission mechanism provided on the rear-end lateral translation mechanism. During operation, the rear-end longitudinal transmission mechanism translates on the rear-end lateral translation mechanism to the current sample transmission channel to longitudinally transmit the sample bucket to be sampled to the rear-end longitudinal transmission mechanism and then translates to the sample preparation device for sample preparation / or drives the empty sample bucket to translate laterally to the first temporary sample transmission channel or the second temporary sample transmission channel after sample preparation to longitudinally transmit the empty sample bucket to the first temporary sample transmission channel or the second temporary sample transmission channel.

[0027] As a further improvement of the present invention, a rear-end positioning assembly is provided on the rear-end longitudinal transmission mechanism for forming a sample bucket positioning area on the rear-end longitudinal transmission mechanism. The rear-end longitudinal transmission mechanism is provided with a rear-end roller assembly capable of forward and reverse transmission. The rear-end positioning assembly includes two rear-end positioning plates provided at the left and right ends of the rear-end roller assembly, and is used to clamp and limit the sample bucket between the two rear-end positioning plates.

[0028] As a further improvement of the present invention, fourth sample bucket blocking mechanisms are provided at the front and rear ends of the rear-end longitudinal transmission mechanism in the transmission direction of the rear-end roller assembly for limiting the sample bucket on the rear-end roller assembly.

[0029] Compared with the prior art, the advantages of the present invention are as follows:

[0030] First, a sample sampling, mixing and batch-assembling system of the present invention has a compact and simple structure. The front-end docking transmission unit, the rear-end docking transmission unit and the batch-assembling conveying unit effectively connect the transport vehicle and the new materials of the sample preparation equipment. And only one set of transmission line can complete the pre-batch assembly of the sample buckets to be prepared, the mixing and batch-assembling transportation of sample buckets in different batches, and the collective transportation of empty sample buckets. It is small in volume and occupies a small area, and is suitable for flexible industrial placement and use.

[0031] Second, a sample sampling, mixing and batch-assembling system of the present invention no longer uses cyclic transmission for batch assembly. The method of hooking and sorting is fast, accurate and simple. The sample bucket batch-assembling time is short, the batch-assembling rhythm is fast, and the work efficiency is high.

[0032] Third, a sample sampling, mixing and batch-assembling system of the present invention eliminates the multiple read-write cards of the sample bucket. The equipment only needs to read the card once, and then the required batch of sample buckets can be selected. It has high reliability and high attention efficiency.

[0033] Fourth, a sample sampling, mixing and batch-assembling system of the present invention. The lateral translation mechanism has a certain translation length. When the transport vehicle reverses, as long as it reverses within the length distance of the lateral translation mechanism (instead of necessarily precisely reversing to a certain point), rapid and accurate docking and transportation can be achieved. This greatly reduces the requirements for the parking accuracy of the transfer trolley and the requirements for vehicle operators, and has a high degree of automation and high work efficiency.

[0034] Fifth, a sample sampling, mixing and batch-assembling system of the present invention can form a rapid docking with the transfer trolley. It not only ensures the precise docking of the longitudinal transmission mechanism and the carriage in the early stage, but also because a positioning assembly is provided on the longitudinal transmission mechanism, multiple sample bucket positioning areas can be formed on the longitudinal transmission mechanism, ensuring that the sample bucket can be accurately carried onto the longitudinal transmission mechanism during subsequent longitudinal transmission and accurately transmitted to the first temporary sample transmission channel or the second temporary sample transmission channel, making the sample bucket transmission precise.

[0047] The present invention will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0048] As Figures 1 to 10As shown in the figure, the present invention provides a sample sampling, preparation and homogenization batch combining system, including a control unit (not shown in the figure), a front-end docking and transmission unit 1, a rear-end docking and transmission unit 2, and more than one batch combining and conveying unit 3 arranged between the front-end docking and transmission unit 1 and the rear-end docking and transmission unit 2. The front-end docking and transmission unit 1 is used to dock with a transport vehicle (such as A shown in the figure), and the rear-end docking and transmission unit 2 is used to dock with a sample preparation device (such as C shown in the figure). The batch combining and conveying unit 3 includes a transmission frame 31, and the transmission frame 31 is provided with a plurality of leg assemblies (clearly shown but not numbered in the figure) for support. A plurality of rollers 32 are arranged on the transmission frame 31 to form a roller transmission line capable of forward and reverse transmission for transmitting sample barrels 9; a plurality of lifting and limiting mechanisms 33 are arranged on the transmission frame 31 and can protrude upward from the gaps between adjacent rollers 32. The plurality of lifting and limiting mechanisms 33 are arranged in two parallel columns along the transmission direction to divide the roller transmission line into a first temporary storage sample transmission channel 311, a current sample transmission channel 312, and a second temporary storage sample transmission channel 313 in sequence from left to right when lifted. The first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 are used to temporarily store the sample barrels 9 to be prepared transmitted by the front-end docking and transmission unit 1 / or the empty sample barrels 9 after sample preparation transmitted by the rear-end docking and transmission unit 2; a plurality of double-sided hook barrel mechanisms 34 are arranged on the transmission frame 31 along the transmission direction; during operation, under the control instruction of the control unit, the plurality of lifting and limiting mechanisms 33 descend so that the double-sided hook barrel mechanisms 34 can hook the sample barrels 9 of the same batch on the first temporary storage sample transmission channel 311 or the second temporary storage sample transmission channel 313 to the current sample transmission channel 312, and then the plurality of lifting and limiting mechanisms 33 rise so that the roller transmission line can forwardly transmit the sample barrels 9 of the same batch on the current sample transmission channel 312 to the rear-end docking and transmission unit 2 / or reversely transmit the empty sample barrels 9 of the same batch to the front-end docking and transmission unit 1.

[0049] The specific implementation principle is as follows:

[0050] It should be noted that the following descriptions of directions are all based on the directions shown in the figures for the convenience of understanding, rather than limitations on the technical solutions. In this embodiment, there are two sets of batch sorting and conveying units 3 arranged in parallel between the front-end docking and conveying unit 1 and the rear-end docking and conveying unit 2. Of course, in other embodiments, three sets, four sets or even more batch sorting and conveying units 3 can also be set according to actual needs. Assume that the trolley transports three batches of sample barrels 9, namely E, F, and G, and the multiple sample barrels 9 in each batch are randomly and disorderly placed. After the trolley is docked with the front-end docking and conveying unit 1, a plurality of lifting and limiting mechanisms 33 rise, dividing the roller conveyor line into a first temporary storage sample transmission channel 311, a current sample transmission channel 312, and a second temporary storage sample transmission channel 313 from left to right in sequence. Then, the trolley transports the disorderly placed multiple sample barrels 9 to the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 through the front-end docking and conveying unit 1. During transmission, since the plurality of lifting and limiting mechanisms 33 rise to form isolation and limitation, the sample barrels 9 on the two channels of the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 can be normally conveyed in sequence.

[0051] In this embodiment, a code reading mechanism is provided on the front-end docking and conveying unit 1. The code reading mechanism is communicatively connected to the control unit of the present invention. Each time the trolley outputs a sample barrel 9, the information on the top cover of the sample barrel 9 (prior art) is read, the sample barrel 9 is numbered, and the information is transmitted to the control unit. For example, the first output is recorded as barrel No. 1 of batch E and is the first one on the first temporary storage sample transmission channel 311, the second output is recorded as barrel No. 1 of batch F and is the second one on the first temporary storage sample transmission channel 311, and so on. In short, the control unit can know the positions of all the sample barrels 9 of any batch on the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313. Of course, in other embodiments, a code reading mechanism can also be directly provided on the trolley for reading, or a code reading mechanism can be directly provided at the front end of the batch sorting and conveying unit 3. This is not a limitation of this application, as long as the control unit can receive all the data.

[0052] When all the transmissions are in place (such as Figure 1In the state shown, the sample combining and batch returning operation starts. Multiple lifting limit mechanisms 33 descend, and then the control unit issues a control instruction to the double-sided hook bucket mechanism 34 to hook all the sample buckets 9 of batch E on the first temporary sample transfer channel 311 and / or the second temporary sample transfer channel 313 to the current sample transfer channel 312 in the middle. At this time, the sorting and sample combining and batch returning of all the sample buckets 9 of batch E are completed. Then, the multiple lifting limit mechanisms 33 are raised to form a limit channel. At this time, the roller conveyor line forwards the sample buckets 9 of the same batch to be processed on the current sample transfer channel 312 to the rear docking transfer unit 2, and is transmitted through the rear docking transfer unit 2 to the sample preparation equipment for sample preparation. Subsequently, the sample combining and batch returning and transmission of batches F and G can be carried out. The first temporary sample transfer channel 311 and the second temporary sample transfer channel 313 can also be used to temporarily store the empty sample buckets 9 after sample preparation. After the sample preparation is completed, the empty sample buckets 9 are reversely transmitted and all are transmitted to the trolley through the front docking transfer unit 1. In the above description, when the roller conveyor line forwards the sample buckets 9 of batch E to be processed on the current sample transfer channel 312, there are various ways to prevent the sample buckets 9 of other batches on the first temporary sample transfer channel 311 and the second temporary sample transfer channel 313 from being transmitted: First, multiple rollers 2 on the transfer rack 1 operate independently. For example, when the multiple rollers 32 of the current sample transfer channel 312 operate, the multiple rollers 32 of the first temporary sample transfer channel 311 and the second temporary sample transfer channel 313 do not operate. Second, the rollers 32 of the first temporary sample transfer channel 311, the current sample transfer channel 312, and the second temporary sample transfer channel 313 run together. However, as described below, a third bucket blocking mechanism 35 that can protrude upward from the gap between adjacent rollers 2 is provided at the transfer rear ends of the first temporary sample transfer channel 311 and the second temporary sample transfer channel 313 on the transfer rack 31. When the current sample transfer channel 312 is transferring, the third bucket blocking mechanism 35 blocks the first sample bucket 9 on the first temporary sample transfer channel 311 and the second temporary sample transfer channel 313, so that the first sample bucket 9 and all subsequent sample buckets 9 will not continue to be transmitted forward. Only in this process, the sample buckets 9 of subsequent batches F and G may move and change positions (because there are empty spaces after the sample buckets 9 of batch E are hooked out on the first temporary sample transfer channel 311 and the second temporary sample transfer channel 313). However, at this time, the control unit controls through an algorithm and recalculates the new positions of the sample buckets 9 of batches F and G after the position change. When the next batch F sample combining is carried out, all the sample buckets 9 of batch F after the change can be accurately hooked again.

[0053] Through the above special scientific design, the following technical advantages are achieved:

[0054] First, a sample collection, preparation, and homogenization batch - combining system of the present invention has a compact and simple structure. The front - end docking and transmission unit 1, the rear - end docking and transmission unit 2, and the batch - combining conveying unit 3 effectively connect the transport vehicle and the new materials of the sample - preparation equipment. And only one set of transmission lines can complete the pre - batch collection of the sample barrels 9 to be prepared, the batch - combining and conveying of sample barrels 9 of different batches, and the collective conveying of empty sample barrels 9. It is small in volume and occupies a small area, suitable for flexible industrial placement and use.

[0055] Second, a sample collection, preparation, and homogenization batch - combining system of the present invention no longer uses cyclic transmission for batch - combining. The method of hooking and sorting is fast, accurate, and simple. The batch - combining time of the sample barrels is short, the batch - combining rhythm is fast, and the work efficiency is high.

[0056] Third, a sample collection, preparation, and homogenization batch - combining system of the present invention eliminates the multiple card - reading and writing of the sample barrels 9. The equipment only needs to read the card once, and then the required batch of sample barrels 9 can be selected. It has high reliability and high attention efficiency.

[0057] Furthermore, in a preferred embodiment, the front - end docking and transmission unit 1 includes a horizontal translation mechanism 11 and a longitudinal transmission mechanism 12 provided on the horizontal translation mechanism 11. A positioning component 13 is provided on the longitudinal transmission mechanism 12 to form a plurality of sample - barrel positioning areas on the longitudinal transmission mechanism 12. A detection switch component 14 for detecting the position of the transport vehicle carriage is also provided on the longitudinal transmission mechanism 12. During operation, the longitudinal transmission mechanism 12 translates on the horizontal translation mechanism 11 and forms a docking with the carriage through the detection switch component 14 to longitudinally transmit a plurality of sample barrels in the carriage to the sample - barrel positioning areas, and then translates through the horizontal translation mechanism 11 to the first temporary - sample transmission channel 311 and the second temporary - sample transmission channel 313 to longitudinally transmit the plurality of sample barrels to the first temporary - sample transmission channel 311 and the second temporary - sample transmission channel 313. The specific implementation principle is as follows:

[0058] The lateral translation mechanism 11 has a certain translation length, which is much longer than the width of the carriage. The detection switch assembly 14 uses a laser detector or a position sensor, etc. When the transporter reverses, it only needs to reverse within the length distance of the lateral translation mechanism 11. At this time, the longitudinal transmission mechanism 12 will translate on the lateral translation mechanism 11. When the detection switch assembly 14 on the longitudinal transmission mechanism 12 detects the position of the transporter carriage, it will accurately stop translating and form an accurate docking with the carriage. At this time, the sample bucket 9 in the carriage is longitudinally transported to the sample bucket positioning area, and then the longitudinal transmission mechanism 12 is laterally translated to the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313, and then multiple sample buckets are longitudinally transported to the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313. Moreover, since the longitudinal transmission mechanism 12 is also provided with a positioning assembly 13, multiple sample bucket positioning areas can be formed on the longitudinal transmission mechanism 12, which not only ensures the accurate docking between the longitudinal transmission mechanism 12 and the carriage in the early stage, but also ensures that the sample bucket can be accurately carried onto the longitudinal transmission mechanism 12 during subsequent longitudinal transmission and accurately transmitted to the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313. Through the above scientific design, the following technical advantages are achieved:

[0059] First, the lateral translation mechanism 11 has a certain translation length. When the transporter reverses, it only needs to reverse within the length distance of the lateral translation mechanism 11 (instead of necessarily reversing accurately to a certain point), and rapid and accurate docking and transportation can be achieved. This greatly reduces the requirements for the parking accuracy of the transfer trolley and the requirements for vehicle operators, with high automation and high work efficiency.

[0060] Second, it can form a rapid docking with the transfer trolley. Not only does it ensure the accurate docking between the longitudinal transmission mechanism 12 and the carriage in the early stage, but also since the longitudinal transmission mechanism 12 is also provided with a positioning assembly 3, multiple sample bucket positioning areas can be formed on the longitudinal transmission mechanism 12, ensuring that the sample bucket can be accurately carried onto the longitudinal transmission mechanism 12 during subsequent longitudinal transmission and accurately transmitted to the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313, making the transmission of the sample bucket 9 accurate.

[0061] Furthermore, in a preferred embodiment, the longitudinal transmission mechanism 12 is provided with a roller assembly 121 that can drive in both forward and reverse directions. The positioning assembly 13 includes two first positioning plates 131 and two second positioning plates 132. One first positioning plate 131 is provided at each end near the left and right ends of the roller assembly 121, and the two second positioning plates 132 are arranged in parallel in the middle of the roller assembly 121 to sandwich and limit the sample bucket 9 within the sample bucket positioning area formed between the adjacent first positioning plate 131 and the second positioning plate 132.

[0062] Further, in a preferred embodiment, the front and rear ends of the first positioning plate 131 and the second positioning plate 132 are both inclined, and are used to make the front and rear ends of the adjacent first positioning plate 131 and the second positioning plate 132 cooperate to form a flared shape to guide the sample bucket 9 being transported. This enables the sample bucket 9 to be guided and accurately and quickly transported to the sample bucket positioning area when the sample bucket 9 to be sampled is transported onto the longitudinal transport mechanism 12, or when the empty sample bucket 9 after sampling is transported onto the longitudinal transport mechanism 12 by the batch-return conveying unit 3.

[0063] Further, in a preferred embodiment, the positioning assembly 13 further includes a plurality of fixing rods. One end of each fixing rod is fixed to the longitudinal transport mechanism 12, and the other end extends upward from the gap between the rollers of the roller assembly 121 to fix the second positioning plate 132.

[0064] Further, in a preferred embodiment, each sample bucket positioning area can carry more than two sample buckets 9 longitudinally. A bracket 122 is further provided above the sample bucket positioning area on the longitudinal transport mechanism 12. A card reader 123 is provided at the corresponding bearing position of each sample bucket 9 to read the information on each sample bucket 9 below and transmit it to the control unit. That is, the longitudinal transport mechanism 12 can carry and transport more than four sample buckets 9 at a time, and the transfer efficiency is extremely high. And the card reader 123 can read the information on each sample bucket 9 below (for example, a chip is provided on the top of the sample bucket in the prior art, or a two-dimensional code is provided, and each sample bucket has an independent label and information), so that the information can be read synchronously and quickly during transfer, and this information can be used by the batch-return conveying unit 3 to provide a decision guarantee for subsequent sorting and conveying, with high intelligence and automation.

[0065] Further, in a preferred embodiment, a first bucket blocking mechanism 124 is further provided at the rear end of the longitudinal transport mechanism 12 in the transport direction of the roller assembly 121. The first bucket blocking mechanism 124 includes a first cylinder 1241 and a first bucket blocking plate 1242 connected to each other. The first cylinder 1241 drives the first bucket blocking plate 1242 to extend upward from the gap between the rollers to limit the sample bucket on the roller assembly 121. When the sample bucket 9 to be sampled is transported from the transport vehicle onto the longitudinal transport mechanism 12, the first bucket blocking mechanism 124 extends, so that the first row of sample buckets 9 transported onto the roller assembly 121 will be limited and will not be continuously transported. When the longitudinal transport mechanism 12 is translated to the batch-return conveying unit 3 for longitudinal transport, the first bucket blocking mechanism 124 drops and no longer limits.

[0066] Further, in a preferred embodiment, a second bucket-blocking mechanism 125 is further provided at the front end of the longitudinal transmission mechanism 12 in the transmission direction of the roller assembly 121. The second bucket-blocking mechanism 125 includes a second air cylinder 1251 and a second bucket-blocking plate 1252 which are connected to each other. The second air cylinder 1251 drives the second bucket-blocking plate 1252 to extend upward from the roller gap for limiting the sample bucket on the roller assembly 121. When the batch delivery unit 3 transports the empty sample bucket 9 that has been sampled to the longitudinal transmission mechanism 12, the second bucket-blocking mechanism 125 extends, so that the empty sample bucket 9 in the first row transported to the roller assembly 121 will be limited and will not be continuously transported.

[0067] Further, in a preferred embodiment, the lateral translation mechanism 11 includes a horizontally arranged frame 111. A slide rail assembly 112 and a lateral drive assembly 113 are provided on the frame 111. The longitudinal transmission mechanism 12 is slidably and limitedly installed on the slide rail assembly 112 and is used to laterally slide along the slide rail assembly 112 under the drive of the lateral drive assembly 113. The lateral drive assembly 113 can adopt a lead screw assembly or an air cylinder assembly, etc.

[0068] Further, in a preferred embodiment, a plurality of positioning switches are provided on the frame 111 for positioning the translation position of the longitudinal transmission mechanism 12. An extreme limit switch is provided at each of the left and right ends of the frame 111. This effectively ensures an excellent lateral translation effect and high lateral translation accuracy, and further effectively ensures the normal progress of subsequent longitudinal transportation.

[0069] Further, in a preferred embodiment, at the transmission rear ends of the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313 on the transmission rack 31, there is respectively provided a third bucket blocking mechanism 35 that can protrude upward from the gap between adjacent rollers 32. When the roller transmission line is sending out the sample buckets 9 of the same batch on the current sample transmission channel 312 forward for sample preparation, the two third bucket blocking mechanisms 35 protrude to prevent the sample buckets 9 on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313 from being sent out forward. That is to say, the rollers 32 of the first temporary sample transmission channel 311, the current sample transmission channel 312, and the second temporary sample transmission channel 313 of the present invention are co-linear, which greatly reduces the manufacturing cost and control cost of the equipment. When the trolley transports all the sample buckets 9 to be prepared to the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313, the two third bucket blocking mechanisms 35 will rise to block the first sample bucket 9 to be prepared on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313, and finally all the sample buckets 9 to be prepared are gathered on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313. As described above, when the current sample transmission channel 312 is transmitting, the third bucket blocking mechanism 35 will also block the first sample bucket 9 on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313. When it is necessary to transport empty buckets to the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313, the two third bucket blocking mechanisms 35 will lower.

[0070] Further, in a preferred embodiment, at the transmission front ends of the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313 on the transmission rack 31, there is also respectively provided a third bucket blocking mechanism 35 that can protrude upward from the gap between adjacent rollers 32. When the roller transmission line is sending out the empty sample buckets 9 of the same batch on the current sample transmission channel 312 in the reverse direction, the two third bucket blocking mechanisms 35 protrude to prevent the sample buckets 9 on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313 from being sent out in the reverse direction.

[0071] Further, in a preferred embodiment, at the transmission front end and the transmission rear end of the current sample transmission channel 312 on the transmission rack 31, there is also respectively provided a third bucket blocking mechanism 35 that can protrude upward from the gap between adjacent rollers 32, so as to limit the transmission of the sample buckets 9 on the current sample transmission channel 312 at the protruding position. When multiple sample buckets 9 of this batch retrieved by hooking are carried on the current sample transmission channel 312, these sample buckets 9 are not closely adjacent to each other. To facilitate the continuity of subsequent sample preparation operations, at this time, the third bucket blocking mechanism 35 at the transmission rear end of the current sample transmission channel 312 is raised, and then the current sample transmission channel 312 starts to transmit. The first sample bucket 9 will be blocked by this third bucket blocking mechanism 35, and then the subsequent sample buckets 9 continue to transmit until they are closely adjacent to each other in a row, and then the third bucket blocking mechanism 35 is lowered, and then the sample preparation operation starts.

[0072] Further, in a preferred embodiment, the third bucket blocking mechanism 3 includes a cylinder and a bucket blocking plate disposed below the roller 32 for upwardly extending the bucket blocking plate from the gap between the rollers 32 under the drive of the cylinder for blocking. This design does not occupy space and has a simple and compact structure.

[0073] Further, in a preferred embodiment, the lifting limit mechanism 33 includes a mounting seat 331, a limit guide rail 332, and a third cylinder 333 disposed below the roller 32. The limit guide rail 332 and the third cylinder 333 are vertically fixed on the transmission frame 31. The mounting seat 331 is connected to both the limit guide rail 332 and the third cylinder 333 for driving the mounting seat 331 to lift along the limit guide rail 332 under the drive of the third cylinder 333. A plurality of limit frames 334 arranged along the transmission direction are mounted on the mounting seat 331, and each limit frame 334 can extend upward from the gap between adjacent rollers 32 to form a limit.

[0074] Further, in a preferred embodiment, the double-sided bucket hooking mechanism 34 includes a mounting bracket 341 disposed below the roller 32. The mounting bracket 341 is axially fixed on the transmission frame 31 along the roller 32. A limit slide rail 342 and a driving assembly 343 are provided axially on the mounting bracket 341. A bucket hooking bent plate 344 extending upward from the gap between adjacent rollers 32 is provided at each end of the mounting bracket 341. Both bucket hooking bent plates 344 are connected to the limit slide rail 342 and the driving assembly 343. When hooking is not required, the bucket hooking bent plates 344 retract to both sides of the roller transmission line so as not to obstruct the sample buckets 9 transported on the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313. When hooking is required, the driving assembly 343 drives the corresponding bucket hooking bent plate 344 to run towards the current sample transmission channel 312 to hook the sample bucket 9 originally on the first temporary storage sample transmission channel 311 or the second temporary storage sample transmission channel 313 to the current sample transmission channel 312.

[0075] Further, in a preferred embodiment, two position detectors 345 are further provided on the mounting bracket 341. The position detectors 345 are communicatively connected to the driving assembly 343 for controlling the moving stroke of the bucket hooking bent plate 344 to make the movement safe and reliable.

[0076] Further, in a preferred embodiment, the rear-end docking and transmission unit 2 includes a rear-end lateral translation mechanism 21 and a rear-end longitudinal transmission mechanism 22 provided on the rear-end lateral translation mechanism 21. During operation, the rear-end longitudinal transmission mechanism 22 translates on the rear-end lateral translation mechanism 21 to the current sample transmission channel 312 to longitudinally transmit the sample bucket 9 to be sampled onto the rear-end longitudinal transmission mechanism 22, and then translates to the sample preparation device for sample preparation / or after sample preparation, drives the empty sample bucket 9 to laterally translate to the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313 to longitudinally transmit the empty sample bucket 9 onto the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313.

[0077] Further, in a preferred embodiment, a rear-end positioning component 23 is provided on the rear-end longitudinal transmission mechanism 22 to form a sample bucket positioning area on the rear-end longitudinal transmission mechanism 22. A rear-end roller component 221 capable of forward and reverse transmission is provided on the rear-end longitudinal transmission mechanism 22. The rear-end positioning component 23 includes two rear-end positioning plates provided at the left and right ends of the rear-end roller component 221, and is used to clamp and limit the sample bucket 9 between the two rear-end positioning plates.

[0078] Further, in a preferred embodiment, fourth sample bucket blocking mechanisms 222 are provided at the front and rear ends of the rear-end longitudinal transmission mechanism 22 in the transmission direction of the rear-end roller component 221, to be used for limiting the sample bucket 9 on the rear-end roller component 221.
