Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of coal sampling and sample preparation, and in particular to a robot intelligent dichotomizer and a method for using the same. Background Art
[0002] When conducting coal quality testing, the uniformity and particle size of coal samples are important foundations for accurately reflecting the characteristics of coal quality. Coal sample preparation is a key link in the entire testing process, and its quality is directly related to the accuracy and reliability of the test results. Coal samples with poor uniformity may lead to distorted test results, which in turn affects the quality assessment of coal combustion, economic benefit analysis, and carbon emission accounting. Therefore, how to prepare coal samples scientifically and accurately is of great significance for a comprehensive understanding of coal quality and optimizing coal utilization. In the process of coal sample preparation, reduction is an important part of determining the representativeness of coal samples. The purpose of reduction is to divide the original coal sample into smaller uniform samples according to a specific ratio to ensure that each sample can truly reflect the composition characteristics of the original coal sample.
[0003] The existing splitter is usually composed of a sample trough, a sample bucket, a sample receiver, a rack and a dustpan, and is divided into four specifications according to the different sample particle sizes, which are used for the reduction of samples of different particle sizes. In the reduction sampling and analysis of coal, ore or other uneven granular materials, the splitter is a commonly used device. Its reduction principle usually adopts a scraper mode, and the coal sample is intercepted in the coal flow to achieve quantitative reduction.
[0004] However, at present, coal sample preparation still requires a lot of manual work, which is labor-intensive and inefficient. At the same time, since coal powder is easy to clog, errors are difficult to avoid during the sample preparation process, resulting in poor uniformity and accuracy of the reduction. In addition, the reduction efficiency of traditional equipment is low, which cannot meet the needs of modern industry for efficient and accurate coal sample preparation. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention provides a robot intelligent binary divider and a method for using the same, which solves the problems existing in the current coal sampling process, such as large amount of manual participation, high labor intensity, low efficiency, easy clogging of the binary divider grid, large deviation in the weight of sub-samples after binary division of coal samples, lack of representativeness, and difficulty in controlling sampling errors.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a robot intelligent binary divider and a method of using the same, including a robot intelligent binary divider fixing seat and a binary algorithm enabling control unit, an automatic material unloading mechanism is arranged on the top of the robot intelligent binary divider fixing seat, a bracket is installed on the top of the robot intelligent binary divider fixing seat, an automatic reciprocating binary dividing mechanism is arranged on the top of the bracket, and an automatic cleaning mechanism and an automatic weighing and sample retention mechanism are arranged in the middle of the bracket from top to bottom.

[0011] Preferably, the top of the bracket is in a rectangular frame structure for supporting the mechanical reciprocating movement mechanism and its related components. The bracket has a load-bearing capacity and can stably fix the entire device.
[0012] Preferably, the shape of the sample collecting hopper is an inverted trapezoid, and the width of the bottom opening is matched with the width of the upper part of the splitter grid, so as to facilitate the uniform inflow and distribution of coal samples.
[0013] Preferably, the inner wall surface of the blanking hopper is designed to be smooth, and the inclination angle ranges from 30 to 45 degrees, which can effectively reduce the adhesion of coal samples and improve the blanking efficiency.
[0014] Preferably, the drainage grooves are symmetrically distributed arc-shaped structures, and their inner walls are smooth to reduce the retention of coal samples and are respectively connected to the sample retaining hopper and the waste sample hopper.
[0015] Preferably, after the equipment is started, the binary algorithm empowered control unit activates the program. The robot grabs the coal sample and pours it into the sample collecting hopper. The motor drives the mechanical reciprocating movement mechanism to drive the sample collecting hopper to move reciprocally. The coal sample is evenly distributed through the grid slots and drainage grooves of the riffle. At the same time, the vibrator cleans the remaining coal to ensure the smoothness of the grid slots of the riffle. The coal sample is diverted to the retained sample hopper and the discarded sample hopper.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] Please see attached Figure 1 The embodiment of the present invention provides a robot intelligent binary divider and a method for using the same, including a robot intelligent binary divider fixing seat 10 and a binary algorithm enabling control unit 15. The top of the robot intelligent binary divider fixing seat 10 is provided with an automatic material unloading mechanism, the top of the robot intelligent binary divider fixing seat 10 is installed with a bracket 9, the top of the bracket 9 is provided with an automatic reciprocating binary dividing mechanism, and the middle of the bracket 9 is provided with an automatic cleaning mechanism and an automatic weighing and retaining mechanism from top to bottom. The robot intelligent binary divider fixing seat 10 is the basic structure of the entire device, which plays a supporting and stabilizing role, and is used to provide a fixed position for all components of the robot intelligent binary divider, ensuring that the device remains stable during operation and avoiding errors or failures caused by vibration or external forces. The bracket 9 is used to provide an installation and support platform for all mechanisms, carrying the automatic reciprocating binary dividing mechanism, the automatic cleaning mechanism and the automatic weighing and retaining mechanism, ensuring that reasonable space and position are maintained between each module, so as to facilitate collaborative work. The binary algorithm enabling control unit 15 is the core module of the robot intelligent binary divider, responsible for coordinating and optimizing the control of each component of the device, and realizing accurate reduction and efficient operation of coal samples. The control unit combines real-time data acquisition, intelligent algorithm calculation, execution control and dynamic adjustment to ensure the accuracy, efficiency and stability of the reduction process. The automatic unloading mechanism is used for the robot 14 to replace manual unloading of the coal sample unloading hopper 13. The automatic reciprocating two-part mechanism is used to achieve smooth and uniform two-partitioning of coal powder. The automatic cleaning mechanism is used to automatically clean the remaining coal in the two-partitioner grid 4. The automatic weighing sample retention mechanism is used to realize automatic temporary storage of samples.
[0025] Please see attached Figure 1The automatic material pouring mechanism includes a robot 14 and a material pouring hopper 13. The bottom of the robot 14 is fixedly connected to the top of the robot intelligent divider fixing seat 10. The end of the robot 14 away from the robot intelligent divider fixing seat 10 is equipped with a material pouring hopper 13. The inner wall of the material pouring hopper 13 is designed to be smooth, with an inclination range of 30-45 degrees, which can effectively reduce the adhesion of coal samples and improve the material pouring efficiency. The robot 14 is the core executive component of the automatic material pouring mechanism, responsible for controlling the up and down movement of the material pouring hopper 13, realizing the grabbing, transportation and uniform material pouring of coal samples, and is used to replace manual operation, accurately grab coal samples and complete material pouring, control the position and angle of the material pouring hopper 13, ensure that the coal samples are smoothly poured into the sample collecting hopper 1 and improve the material pouring efficiency, and avoid unevenness and errors in manual material pouring. The pouring hopper 13 is used to hold coal samples and complete fixed-point pouring. Under the control of the robot 14, the pouring hopper 13 pours the coal samples evenly into the sample collecting hopper 1 below. The internal design inclination angle is generally 30-45 degrees to ensure that the coal samples slide out smoothly, reduce adhesion and residue, and ensure that the coal samples are evenly distributed during the pouring process, providing a guarantee for the subsequent precise binary separation.
[0026] Please refer to the attached Figure 1 The automatic reciprocating two-part mechanism includes a motor 11, which is fixedly connected to the outside of the bracket 9. A mechanical reciprocating mechanism 2 is installed at the output end of the motor 11. The mechanical reciprocating mechanism 2 is fixedly connected to the top of the bracket 9. A sample collecting bucket 1 is installed in the middle of the mechanical reciprocating mechanism 2. A two-partitioning device grid 4 is installed at the bottom of the mechanical reciprocating mechanism 2. The top of the bracket 9 is a rectangular frame structure for supporting the mechanical reciprocating mechanism 2 and its related components. The bracket 9 has a bearing capacity and can stably fix the entire device. The sample collecting bucket 1 is in the shape of an inverted trapezoid, and the bottom opening width matches the slot width of the upper part of the two-partitioning device grid 4 to facilitate the uniform inflow and distribution of coal samples. The motor 11 is the power source for the operation of the mechanical reciprocating mechanism 2 and is the core driving component of the entire device. It provides energy for the mechanical reciprocating mechanism 2 so that it can achieve reciprocating motion. The mechanical reciprocating mechanism 2 is used to convert the rotational motion of the motor 11 into a linear reciprocating motion, so that the device can reciprocate within a certain range, which is convenient for the uniform distribution and separation of coal samples. The sample collecting hopper 1 is used to collect coal samples and is the initial container for the coal samples to enter the separation device. The coal samples are introduced into the divisor grid 4 through the sample collecting hopper 1. The divisor grid 4 is used to separate the coal samples. Through reciprocating motion and a specially designed trough body, the coal samples are divided into two uniform parts to achieve the divisor operation of the sample.
[0027] Please refer to the attached Figure 1The automatic cleaning mechanism includes a jar 3, which is installed on the outside of the divider grid 4. Two drainage grooves 5 are installed directly below the divider grid 4. The jar 3 is used to clean the residual coal sample in the divider grid 4. By vibrating, the coal sample particles attached to the inside of the divider grid 4 fall off to avoid blockage and ensure the cleanliness of the divider grid 4, thereby ensuring the accuracy and stability of the subsequent separation process. The two drainage grooves 5 are located directly below the divider grid 4 and are used to send the coal material that has been divided into the sample retaining bucket 7 and the sample discarding bucket 12 respectively.
[0028] Please see attached Figure 1 The automatic weighing sample retention mechanism includes a sample retention bucket 7 and a sample discarding bucket 12. The sample retention bucket 7 and the sample discarding bucket 12 are both fixedly connected to the outside of the bracket 9 and are respectively located directly below the two drainage grooves 5. The inner bottom wall of the sample retention bucket 7 is fixedly connected to a weighing unit 8. An electromagnetic lock 6 is installed on the outside of the sample retention bucket 7. The drainage groove 5 is a symmetrically distributed arc structure with a smooth inner wall to reduce the retention of coal samples, and is respectively connected to the sample retention bucket 7 and the sample discarding bucket 12. The sample retention bucket 7 is used to receive and store the coal samples flowing in through the drainage groove 5, and to weigh and analyze the coal samples. The sample retention bucket 7 is also the core component for realizing sample retention and weighing. It cooperates with the weighing unit 8 to accurately weigh the samples, complete the sample data recording, and ensure that the quality of the retained samples is controllable. The sample discarding bucket 12 is used to receive non-retained samples flowing in through the drainage groove 5 to ensure that the system can classify and process different types of samples. The weighing unit 8 is installed on the inner bottom wall of the sample hopper 7, and is used to weigh the coal sample entering the sample hopper 7 in real time, and provide accurate measurement data of the coal sample weight for subsequent analysis or quality inspection. The weighing unit 8 is also the core detection element of the entire weighing and sample retention mechanism. The electromagnetic lock 6 is used to control the opening and closing state of the sample hopper 7, ensuring that the sample hopper 7 can release the coal sample or remain in a closed state only at a specified time or under conditions, so as to lock and protect the coal sample in the sample hopper 7, and prevent the coal sample from being lost under unpredictable conditions. At the same time, it can cooperate with the weighing unit 8 to unlock the sample hopper 7 after weighing to transfer the coal sample.
[0029] Working principle: After the equipment is started, the binary algorithm enables the control unit 15 to activate the operating program, control the robot 14 to grab the coal sample from a fixed position, and pour the coal sample into the sample collecting bucket 1. Subsequently, the motor 11 drives the mechanical reciprocating movement mechanism 2 to drive the sample collecting bucket 1 to perform reciprocating motion. The coal sample is evenly distributed through the binary divider grid 4 and the drainage groove 5 according to the set binary rule. At the same time, the vibrator 3 is started to clean the remaining coal in the binary divider grid 4 to ensure smooth flow and avoid blockage. After binary division, the coal samples flow into the sample retention bucket 7 and the discarded sample bucket 12 respectively.
[0030] After the first binary division, the robot 14 moves the dump hopper 13 to the bottom of the sample bucket 7, the electromagnetic lock 6 releases the coal sample, and the robot 14 pours the coal sample in the sample bucket 7 back to the sample collection bucket 1, and performs the binary division operation again to ensure that the final sample reduction meets the high-precision requirements. After the sample division is completed, the weighing unit 8 accurately weighs the coal sample in the sample bucket 7, and transmits the data to the binary algorithm enabling control unit 15, and optimizes and adjusts the sample distribution plan according to the algorithm to ensure that the set different sub-sample requirements are met, such as the specific weight requirements of 3mm analysis samples, full water samples, and retained samples.
[0031] After the reduction is completed, the robot 14 bottles each sub-sample to the designated location and transports the waste sample in the waste sample bucket 12 to the waste material pool. The residual coal is cleaned by the jar 3 to prevent the residue from affecting the next operation, and the equipment automatically enters the ready state. The whole process is completed automatically without manual intervention, ensuring the uniformity, efficiency and accuracy of the reduction, greatly improving the sample preparation quality and operation convenience.
