Description

Sample collection and preparation combined batching system

Technical Field

The utility model mainly relates to the field of material sample collection and preparation equipment, in particular to a sample collection and batch preparation system for sample collection and preparation.

Background

For the sampling and analyzing work of materials (such as ores and coal materials), each country has a mandatory standard, and the sampling and analyzing work must be carried out according to the standard. For example, in the coal analysis, the sampling and analyzing process is based on the principle that the collected sample is gradually reduced in particle size and mass without destroying the representativeness of the sample until the particle size and mass (weight) precision requirements of the sample in laboratory tests are met, and then the sample meeting the requirements is subjected to relevant test analysis. There can be no loss of sample during this process, and no physical or chemical changes to the sample that would affect the final test results.

Currently, the demand for sample collection and preparation integrated operation and collection and preparation integrated system is higher and higher, such as sample collection and batch preparation operation. The sample combination and batch grouping means that different coal samples of multiple batches are prepared and packed by sample barrels at the front end of sample preparation operation, and each batch of coal sample barrels also have a certain number, and the coal samples are disordered in the preparation and transfer processes. Therefore, at the rear end of the sampling operation, the coal samples in different batches, different quantities and disordered sequences need to be gathered together in the same batch, and then the sampling operation of each same batch is completed in a centralized manner.

For example: part of the existing sample combination batch system is provided with a temporary storage transmission line, a sample preparation transmission line and a transfer transmission line which are arranged in parallel; the part is provided with a temporary storage transmission line, a non-current sample transmission line, an empty barrel transmission line and a sample preparation transmission line which are arranged in parallel; and the device is also provided with an empty barrel conveying belt, a sample preparation conveying belt and a batching circulating conveying belt which are arranged in parallel and longitudinally. This has the following technical problems:

firstly, set up so many transfer lines bulky, area is big, is unsuitable for the flexible putting and use of industrialization, if especially will realize the operation of batching of closing the appearance of many batches, return to batch the circulation in order to satisfy the annular and must make the system volume bigger and complicated. Secondly, each transmission line has too single function, the sample barrels need to be circulated on a plurality of conveying mechanisms for many circles in the sample combining and batching process of the sample barrels, the sample barrel circulating conveying takes longer time, the batching time is long, the batching rhythm is slow, and the working efficiency is low. Thirdly, the number of times of reading and writing cards of the sample barrel is large, and sorting is difficult. After all the sample buckets are read once each time, the sample buckets in the required batch can be selected, so that the reliability is reduced.

Also for example: a part of the existing sample collection and batching system for sample collection and preparation is provided with a barrel conveying belt and is used for being directly butted with a transfer trolley for conveying sample barrels, and all sample barrels on the transfer trolley are conveyed to the barrel conveying belt and then conveyed to other conveying belt devices of the sample collection and batching system through the barrel conveying belt. When the empty barrel is discharged, the empty barrel is also conveyed into the transfer trolley through the barrel conveying belt. This has the following technical problems:

firstly, because the width of transport dolly and bucket conveyor belt is about the same, if make the sample bucket make a round trip smoothly between transport dolly and two conveying mechanism of bucket conveyor belt and go into out the bucket, just need align dolly rear of a vehicle with bucket conveyor belt. This makes to transport dolly parking precision requirement higher, if the parking is inaccurate, then need to reverse a car many times and just can align. This makes the requirement high to vehicle operating personnel, and the butt joint is difficult, and the consumption time is long, and degree of automation is low, work efficiency is low.

Secondly, if the sample barrels are misaligned, the automatic in-and-out of the sample barrels is seriously influenced, the sorting and batching efficiency of sample combination and batching is influenced, and the sample barrels can fall down. And the alignment is not uniform, so that the position of the sample barrel transmitted to the barrel feeding transmission belt is not accurate, and the accurate butt joint of the barrel feeding transmission belt and other transmission belt devices of the sample combining and batching system is influenced.

Detailed Description

The present invention will be described in further detail with reference to the following specific embodiments and the accompanying drawings.

As shown in fig. 1 to 10, the present invention provides a specimen sampling and batching system for sampling and preparing specimens, which includes a control unit (not shown in the drawings), a front butt transfer unit 1, a rear butt transfer unit 2, and more than one set of batching and conveying units 3 disposed between the front butt transfer unit 1 and the rear butt transfer unit 2, wherein the front butt transfer unit 1 is used for butting against a conveying vehicle (as shown in a), the rear butt transfer unit 2 is used for butting against a specimen preparing device (as shown in C), the batching and conveying unit 3 includes a conveying frame 31, and the conveying frame 31 is provided with a plurality of supporting leg assemblies (explicitly shown in the drawings but not numbered). The transmission frame 31 is provided with a plurality of rollers 32 and is used for forming a roller transmission line capable of transmitting forward and backward so as to transmit the sample barrel 9; the conveying frame 31 is provided with a plurality of lifting limiting mechanisms 33 which can extend upwards from the gap between adjacent rollers 32, the plurality of lifting limiting mechanisms 33 are arranged in two parallel lines along the conveying direction and are used for sequentially dividing the roller conveying line into a first temporary storage sample conveying channel 311, a current sample conveying channel 312 and a second temporary storage sample conveying channel 313 from left to right during lifting, and the first temporary storage sample conveying channel 311 and the second temporary storage sample conveying channel 313 are used for temporarily storing sample barrels to be prepared 9 conveyed by the front-end butt-joint conveying unit 1 or sample-prepared empty sample barrels 9 conveyed by the rear-end butt-joint conveying unit 2; a plurality of double-side bucket hooking 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 limiting mechanisms 33 descend so that the double-side bucket hooking mechanism 34 hooks the same batch of sample buckets 9 on the first temporary sample transmission channel 311 or the second temporary sample transmission channel 313 onto the current sample transmission channel 312, and then the plurality of lifting limiting mechanisms 33 ascend so that the roller transmission line forwards transmits the same batch of sample buckets 9 to be prepared on the current sample transmission channel 312 to the rear-end butt transmission unit 2 or reversely transmits the same batch of empty sample buckets 9 to the front-end butt transmission unit 1.

The specific implementation principle is as follows:

it should be noted that the following descriptions of the directions are all described according to the directions shown in the drawings for easy understanding, and are not intended to limit the technical solutions. In this embodiment, two sets of batching and conveying units 3 arranged in parallel are arranged between the front end butt joint conveying unit 1 and the rear end butt joint conveying unit 2. Of course, in other embodiments, three, four or even more sets of batching and conveying units 3 can be provided according to actual needs. Assuming that the cart transports E, F, G three batches of sample buckets 9, the multiple sample buckets 9 for each batch are randomly shuffled. After the trolley and the front end butting transmission unit 1 are butted, the plurality of lifting limiting mechanisms 33 are lifted, the roller transmission line is sequentially divided 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, and then the trolley transmits a plurality of sample buckets 9 which are placed in a disordered mode to the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 through the front end butting transmission unit 1. During transmission, because the plurality of lifting limiting mechanisms 33 are lifted to form isolation limiting, the sample buckets 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.

In this embodiment, the front-end docking transmission unit 1 is provided with a code reading mechanism, the code reading mechanism is in communication connection with the control unit of the present invention, and when the cart outputs one sample bucket 9, the information on the top cover of the sample bucket 9 is read (in the prior art), and the sample bucket 9 is numbered and transmitted to the control unit. For example, the first output is designated as bucket number E lot 1 and is the first on the first buffer transport path 311, the second output is designated as bucket number F lot 1, is the second on the first buffer transport path 311, and so on. In any case, the control unit can know at which positions of the first buffer transport path 311 and the second buffer transport path 313 all sample buckets 9 of any one lot are located. Of course, in other embodiments, the code reading mechanism may be directly disposed on the cart for reading, or may be directly disposed on the front end of the batching and conveying unit 3. This is not a limitation of the present application as long as the control unit can accept all the data.

When all the samples are transmitted in place (state shown in fig. 1), the sample grouping operation is started. The plurality of lifting limiting mechanisms 33 descend, then the control unit issues a control instruction to the double-side bucket hooking mechanism 34, all the sample buckets 9 of the E batch on the first temporary storage sample transmission channel 311 and/or the second temporary storage sample transmission channel 313 are hooked to the middle current sample transmission channel 312, and then sorting and sample combining and batching of all the sample buckets 9 of the E batch are completed. Then, the plurality of lifting limiting mechanisms 33 are lifted to form a limiting channel, and at this time, the roller transmission line forwards transmits the sample barrels 9 to be prepared in the same batch on the current sample transmission channel 312 to the rear-end butt joint transmission unit 2, and transmits the sample barrels to be prepared to the sample preparing equipment through the rear-end butt joint transmission unit 2 for sample preparation. And F batches and G batches can be subjected to sampling, grouping and transmission. The first temporary sample storage transmission channel 311 and the second temporary sample storage transmission channel 313 can also be used for temporarily storing the empty sample barrels 9 after sample preparation, and after sample preparation is finished, reverse transmission is carried out to completely transmit the empty sample barrels 9 to the trolley through the front end butt connection transmission unit 1. In the above description, there are several ways how to prevent the sample buckets 9 of other batches on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313 from being transferred out when the roller transmission line is used to forward transfer out the sample buckets 9 to be prepared of E batches on the current sample transmission channel 312: firstly, it is all independently operated that the transport frame 1 is equipped with many rollers 2, for example when many rollers 32 of the present appearance transfer passage 312 were operated, many rollers 32 of first scratch sample transfer passage 311 and second scratch sample transfer passage 313 do not operate. Secondly, the rollers 32 of the first temporary sample transfer path 311, the current sample transfer path 312 and the second temporary sample transfer path 313 are in common, but as described below, a third bucket stopping mechanism 35 which can extend upwards from a gap between adjacent rollers 2 is arranged at the rear end of the first temporary sample transfer path 311 and the second temporary sample transfer path 313 on the transfer frame 31, and when the current sample transfer path 312 is transferred, the third bucket stopping mechanism 35 stops the first sample bucket 9 on the first temporary sample transfer path 311 and the second temporary sample transfer path 313, so that the first sample bucket 9 and all subsequent sample buckets 9 cannot be continuously transferred forwards. Only in this process, the sample buckets 9 of the subsequent F lot and G lot may move to the changed positions (because the empty positions of the sample buckets 9 of the E lot are formed on the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313), but at this time, the control unit performs the algorithm control, and the new positions of the sample buckets 9 of the F lot and G lot after the changed positions have been recalculated, and when the next F lot is closed, all the sample buckets 9 of the changed F lot can be accurately hooked again.

Through the special scientific design, the method has the following technical advantages:

the sample collection and batching system for sample collection and preparation is compact and simple in structure, and the front end butt joint transmission unit 1, the rear end butt joint transmission unit 2 and the batching and conveying unit 3 effectively connect a conveying vehicle with a new material of sample preparation equipment.
