[0042] According to the automatic weighing device of coal sample disclosed in the present invention, it includes: a box body 1, a conveying mechanism 6, a crucible, a sampling component 10, a balance component, a moving component 14 and a control processor, wherein the box body 1 has a closed weighing space 1001, the conveying mechanism 6 is partially arranged outside the box body 1, and the rest is arranged in the weighing space 1001 of the box body 1, the crucible, the sampling component 10, the balance component and the moving component 14 are all arranged in the weighing space 1001, the conveying mechanism 6 transports the coal sample outside the box body 1 to the weighing space 1001 of the box body 1, and weighs the coal sample in the weighing space 1001 through the cooperation of the sampling component 10, the crucible and the balance component, so as to reduce the exposure of the coal sample to the external environment during the weighing process, reduce the possibility of the coal sample being contaminated during the weighing process, ensure the reliability of the purity of the coal sample, and thus improve the accuracy of the coal sample when used for measuring the calorific value of the power plant. At the same time, the weighing space 1001 is a visual space, and the operator can observe the operation process in the weighing space 1001 to monitor the weighing process of the automatic weighing device, thereby ensuring the reliability and safety of the operation of the automatic weighing device. In addition, the control processor is arranged in the box body 1, and the control processor is electrically connected to the transmission mechanism 6, the sampling component 10, the balance component and the moving component 14. Specifically, the control processor controls the transmission mechanism 6 to transmit the coal sample outside the box body 1 to the weighing space 1001 in the box body 1, and then the control processor controls the sampling component 10 to take out part of the coal sample, and the control processor controls the moving component 14 to move the empty crucible to the balance component, and then controls the sampling component 10 to transfer the taken out coal sample to the crucible on the balance component, and the balance component weighs the crucible containing the coal sample and transmits the weighing data to the control processor, and the control processor records the coal sample data, and the control processor controls the moving component 14 to move the weighed crucible containing the coal sample to the placement position.

Specifically, the display area 2 is a display screen, and the display screen is used to display information of the coal sample weighing, such as the number and weight of the coal sample. The key area 3 includes a plurality of operation buttons, such as start, stop, set, etc., to transmit the start, stop or set signals to the control processor, and the control processor controls the action or stop of each component or mechanism according to the signal of the button.

[0044] Furthermore, the box body 1 is provided with a shielding member (not shown in the figure) that can be opened and closed. The shielding member is arranged at the position where the conveying mechanism 6 enters the inside of the box body 1 from the outside of the box body 1. When the conveying mechanism 6 transports the coal sample from the outside of the box body 1 into the weighing space 1001 of the box body 1, the shielding member is in an open state; when the coal sample is weighed in the weighing space 1001, the shielding member is in a closed state, so that the weighing space 1001 is in a closed state, thereby preventing the coal sample from being contaminated by objects outside the box body 1 during the weighing process.

[0045] In some embodiments of the present disclosure, the automatic weighing device of the coal sample includes: a barcode scanner 5, the barcode scanner 5 is electrically connected to the control processor, and the barcode scanner 5 is used to scan the information code of the coal sample bottle 7 containing part of the coal sample. The barcode scanner 5 can be set in the weighing space 1001 in the box body 1, and the barcode scanning is realized by automatic operation, or the barcode scanner 5 is set outside the box body 1, and the barcode scanning is realized by manual operation. After scanning the code, the barcode scanner 5 transmits the scanned code information to the control processor to be recorded in the control processor, and the control processor can display the information obtained by scanning the code by the barcode scanner 5 through the display screen, so as to facilitate the operator to check.

[0046] In some embodiments of the present disclosure, the automatic weighing device of the coal sample includes: a tray assembly 8, the tray assembly 8 is arranged in the weighing space 1001, the tray assembly 8 is arranged near the conveying mechanism 6, and the tray assembly 8 is configured to support the coal sample bottle 7 containing the coal sample. Specifically, the tray assembly 8 is arranged near one end of the conveying mechanism 6 located in the weighing space 1001, so as to transfer the coal sample bottle 7 on the conveying mechanism 6 to the tray assembly 8. The conveying mechanism 6 transports the coal sample bottle 7 containing the coal sample to the weighing space 1001, and the coal sample bottle 7 can be transferred to the tray assembly 8 by a manipulator (not shown in the figure) arranged in the weighing space 1001, or the coal sample bottle 7 can be transferred to the tray assembly 8 by a moving assembly 14 in the weighing space 1001. It should be noted that the moving assembly 14 in the weighing space 1001 can move in the weighing space 1001, so that the moving assembly 14 can transfer the coal sample bottle 7 from the conveying mechanism 6 to the tray assembly 8, and can also move the crucible between the balance assembly and the placement position.

[0047] In some embodiments of the present disclosure, the tray assembly 8 includes: a tray (not shown in the figure) and a rotating member (not shown in the figure), the tray is used to support the coal sample bottle 7, the rotating member is connected to the bottom of the tray, and the rotating member is electrically connected to the control processor. The rotating member is controlled by the control processor to rotate to realize the rotation of the tray, so that the coal sample bottle 7 on the tray rotates, ensuring that the sampling assembly 10 can select coal samples at different positions of the coal sample bottle 7 multiple times, thereby improving the uniformity of coal sample selection. It should be noted that the sampling assembly 10 in this embodiment needs to take coal samples from the coal sample bottle 7 multiple times. Therefore, before each sampling, the control processor controls the rotating member to rotate a certain angle, so that the sampling assembly 10 can take coal samples at different positions in the coal sample bottle 7 without moving the position, so that the coal samples taken by the sampling assembly 10 are more uniform.

[0048] In some embodiments of the present disclosure, the automatic weighing device of the coal sample includes: a bottle opener 4, which is arranged near the tray assembly 8 and is configured to open the coal sample bottle 7.

Before the sampling assembly 10 is sampled, the control processor controls the cleaning brush to clean the sampling assembly 10 to reduce the contamination of the coal sample by the sampling assembly 10 and prevent the coal powder covered on the sampling assembly 10 from affecting the weight of the new coal sample. A waste trough is provided under the cleaning brush. After the cleaning brush cleans the sampling assembly 10, the coal powder covered on the sampling assembly 10 falls into the waste trough to collect the waste coal sample.

The motor drives the sampling rotating member 101 to rotate, the sampling rotating member 101 drives the connecting rod to rotate, and the connecting rod drives the sampling rod to rotate around the axis of the connecting rod. Since the connecting rod is located between the balance assembly and the tray assembly 8, the rotation of the connecting rod can make the sampling rod rotate from the top of the tray assembly 8 to the top of the balance assembly, so as to realize the transfer of coal samples between the tray assembly 8 and the balance assembly.

[0051] In some embodiments of the present disclosure, the moving assembly 14 includes a motor (not shown in the figure), a moving rotating member 141 and a moving member 142, wherein the control processor is electrically connected to the motor, the motor drive is connected to the moving rotating member 141, and the axis of the moving rotating member 141 is connected to the moving member 142.

The motor drives the movable rotating member 141 to rotate, and the movable rotating member 141 drives the rotating rod to rotate, and the rotating rod drives the movable rod to rotate around the axis of the rotating rod. Since the rotating rod is located between the balance assembly and the crucible placement rack, the rotation of the rotating rod can make the movable rod rotate from the top of the tray assembly 8 to the top of the balance assembly, so as to realize the movement of the coal sample from the crucible placement rack to the balance assembly; since the rotating rod is located between the balance assembly and the lifting assembly 15, the rotation of the rotating rod can make the movable rod rotate from the top of the balance assembly to the top of the lifting assembly 15, so as to realize the movement of the coal sample from the balance assembly to the lifting assembly 15.

The moving assembly 14 moves the empty crucible to the center of the balance tray 13, the sensor 11 senses the weight of the empty crucible, and the sensor 11 transmits the weight of the empty crucible to the control processor through the support rod 12, so that the control processor can record the weight. As the sampling assembly 10 continues to add coal samples to the crucible, the sensor 11 continues to transmit the total weight of the crucible and the coal sample contained therein to the control processor.
