[0042] See also Figures 1 to 9The present embodiment provides a coal sample container cleaning device, which can completely clean coal sample containers 100 of different specifications, has high cleaning efficiency and strong versatility. The coal sample container cleaning device comprises a locking mechanism 1, a cleaning mechanism 2 and a blower mechanism. The locking mechanism 1 comprises a locking disk 11 and a plurality of locking assemblies 12. The locking disk 11 is rotatable, and the rotation axis of the locking disk 11 does not coincide with its own axis. The locking disk 11 is axially provided with a through hole 111. The plurality of locking assemblies 12 are circumferentially spaced and arranged on the locking disk 11. Coal sample containers 100 of different calibers can be locked to the locking disk 11 through the locking assemblies 12, so that the inner cavity of the coal sample container 100 is opposite to the through hole 111. The cleaning mechanism 2 includes a lifting cleaning brush 21, which can rotate around its own axis. The rotation axis of the locking disk 11 coincides with the axis of the cleaning brush 21. The cleaning brush 21 is arranged below the locking disk 11. The cleaning brush 21 can extend into the coal sample container 100 through the through hole 111 to clean the coal sample container 100.

Then the cleaning brush 21 is driven to rise until the end of the cleaning brush 21 abuts against the bottom wall of the coal sample container 100. Then the locking disk 11 and the cleaning brush 21 are driven to rotate, and the blower mechanism is started to blow hot air into the inner cavity of the coal sample container 100, so as to clean the coal sample container 100. Multiple locking assemblies 12 can lock coal sample containers 100 of different calibers on the locking disk 11, and by driving the cleaning brush 21 to rise and fall, it can be inserted into coal sample containers 100 of different depths for cleaning, thereby adapting to coal sample containers 100 of different specifications, and having strong versatility. During cleaning, since the rotation axis of the locking disk 11 does not coincide with its own axis but coincides with the axis of the cleaning brush 21, that is, the locking disk 11 rotates eccentrically around the cleaning brush 21, the rotating cleaning brush 21 can completely clean the inner wall of the coal sample container 100, and the rotating locking disk 11 can also drive the coal sample container 100 to shake, so that the residual coal slag in the coal sample container 100 can fall more smoothly.

By moving the first limiting rod 121, the second limiting rod 122 can be limitedly abutted against the side wall of the coal sample container 100, so as to lock the coal sample container 100 to the locking disk 11. Specifically, when installing the coal sample container 100, firstly, the plurality of first limiting rods 121 are driven to move to a suitable position according to the caliber of the coal sample container 100, and the container mouth of the coal sample container 100 is placed downward on the plurality of first limiting rods 121, so that the plurality of first limiting rods 121 jointly support the coal sample container 100; then, the plurality of first limiting rods 121 are driven to move radially again until the plurality of second limiting rods 122 are in contact with the side wall of the coal sample container 100, so that the coal sample container 100 is stably limited on the locking disk 11. In this embodiment, the second limiting rod 122 extends into the coal sample container 100, that is, the second limiting rod 122 is in contact with the inner side wall of the coal sample container 100. In other embodiments, the second limiting rod 122 may not extend into the coal sample container 100, so that the second limiting rod 122 is in contact with the outer side wall of the coal sample container 100, and the coal sample container 100 can also be limited on the locking disk 11.

[0045] In the current embodiment, the first limiting rod 121 and the second limiting rod 122 are arranged vertically. Preferably, the second limiting rod 122 is arranged in an arc shape on one side facing the coal sample container 100, so as to be able to more stably limit and abut against the side wall of the coal sample container 100. Furthermore, an elastic member is arranged on one side of the second limiting rod 122 facing the coal sample container 100, and the second limiting rod 122 can elastically contact the coal sample container 100 through the elastic member, thereby effectively protecting the coal sample container 100 and avoiding scratching the coal sample container 100. Optionally, the elastic member is made of a rubber material, which has high elasticity and good protection effect, and can also increase the friction between the second limiting rod 122 and the coal sample container 100, further improving the stability of the limiting of the coal sample container 100 and the locking disk 11.

[0046] Optionally, a plurality of openings connected to the installation cavity are provided on the side wall of the locking disk 11, and the openings are arranged one-to-one corresponding to the locking assembly 12.

Optionally, a connection seat 112 is provided on the locking disk 11, and the locking driver 13 is rotatably provided on the connection seat 112 to avoid interference with the locking disk 11 when driving the first connecting rod 14 to rotate.

After the coal sample container 100 is locked on the locking disk 11, the lifting drive 23 is first driven to allow the cleaning brush 21 to extend into the interior of the coal sample container 100, and then the cleaning drive 22 is started to drive the cleaning brush 21 to rotate, thereby cleaning the interior of the coal sample container 100, which is convenient to use. Specifically, the lifting drive 23 is arranged on the second mounting plate 32 of the mounting frame 3.

Further, the mounting tube 211 is provided with air holes 213, and the exhaust end of the blower mechanism is connected to the mounting tube 211. When the blower mechanism is started, hot air can be blown into the coal sample container 100 through the air holes 213 on the mounting tube 211. Optionally, the blower mechanism is a fan.

Specifically, a second avoidance hole is provided on the connecting frame 24, and the drainage channel 5 is penetrated through the second avoidance hole in the connecting frame 24 to avoid interference with the connecting frame 24. Optionally, the drainage channel 5 uses a cloth bag, and the cloth belt is easy to obtain and has low cost. Specifically, one end of the cloth bag is connected to the first mounting plate 31 and is opposite to the first avoidance hole 311, and the other end is connected to the second mounting plate 32.

[0055] Optionally, a controller is further included, and the locking mechanism 1, the cleaning mechanism 2 and the blower mechanism are all electrically connected to the controller, and the controller can send signals to the locking mechanism 1, the cleaning mechanism 2 and the blower mechanism to automatically clean the coal sample container 100. In this embodiment, the controller is a PLC controller.

[0056] Optionally, a first detection member 6 is further included, and the first detection member 6 is arranged on the locking disk 11, and is used to detect whether a coal sample container 100 is placed on the locking disk 11. Further, the first detection member 6 is electrically connected to the controller, and is fixed on the locking disk 11 through the first fixing plate 113. The first detection member 6 can detect in real time whether a coal sample container 100 is placed on the locking disk 11 and send the detection result to the controller. If it is detected that a coal sample container 100 is placed on the locking disk 11, the controller drives the locking drive member 13 to lock the coal sample container 100 on the locking disk 11, and then the controller sends a signal to the cleaning mechanism 2 to clean the coal sample container 100. Optionally, the first detection member 6 includes but is not limited to a proximity switch, a micro switch, a travel switch, a photoelectric switch, a diffuse reflection sensor, etc.

[0057] It can be understood that, since the locking drive 13 is connected to the locking structure through the connecting rod structure, that is, the telescopic distance of the output end of the locking drive 13 can be converted into the moving distance of the first limit rod 121, the second limit rod 122 can be limitedly abutted with the coal sample containers 100 of different calibers by controlling the extended distance of the locking drive 13, thereby locking the coal sample container 100. Based on this, a plurality of limit switches are arranged at intervals on the telescopic path of the output end of the locking drive 13, and each limit switch corresponds to a coal sample container 100 of a caliber, thereby limiting the extended length of the locking drive 13 to lock the coal sample containers 100 of different calibers. The number and specific position of the limit switches are determined according to the caliber of the coal sample container 100 to be locked. For example, in this embodiment, two limit switches are arranged to respectively lock the coal sample containers 100 of 300 mm and 400 mm calibers. Furthermore, an identifier electrically connected to the controller is provided, and a specification label is provided on the coal sample container 100. The identifier can identify the specification label to determine the caliber and depth of the coal sample container 100. Optionally, the identifier is a camera.

[0058] In other embodiments, a measuring piece is provided on one side of the second limiting rod 122 facing the coal sample container 100, and the measuring piece is electrically connected to the controller to measure the pressure between the coal sample container 100 and the second limiting rod 122. When the pressure between the coal sample container 100 and the second limiting rod 122 reaches a preset value, it indicates that the coal sample container 100 is locked. Optionally, the measuring piece is a pressure sensor.

[0059] Similarly, a plurality of limit switches are provided on the lifting path of the cleaning brush 21, and different limit switches correspond to coal sample containers 100 of different depths. The controller can control the output end of the lifting drive 23 to extend and retract to the corresponding limit switch position according to the depth of the coal sample container 100, thereby limiting the lifting stroke of the cleaning brush 21 and preventing the cleaning brush 21 from rising excessively and damaging the bristles 212 at the top thereof.

[0060] Further, see Figure 7 , further comprising a second detection member 7, the second detection member 7 is electrically connected to the controller, and the second detection member 7 is used to detect the rotation speed of the locking disk 11. Specifically, the second detection member 7 detects the rotation speed of the locking disk 11 in real time and feeds back to the controller, and the controller calculates the relative rotation speed of the locking disk 11 and the cleaning brush 21 according to the rotation speeds of the locking disk 11 and the cleaning brush 21 (the rotation speed of the cleaning brush 21 is determined according to the rotation speed of the cleaning drive member 22), thereby determining whether the cleaning frequency meets the cleaning requirements. Specifically, if the relative rotation speed is not equal to 0, it means that the cleaning frequency meets the cleaning requirements. Optionally, the second detection member 7 is a speed sensor.

[0061] This embodiment also provides a method for cleaning a coal sample container, using the above-mentioned coal sample container cleaning device, comprising the following steps:

[0062] S1. Lock the coal sample container 100 to the locking disk 11 through the locking assembly 12, so that the inner cavity of the coal sample container 100 is opposite to the through hole 111 of the locking disk 11;

[0063] S2, driving the cleaning brush 21 upward to extend into the inner cavity of the coal sample container 100 until the cleaning brush 21 abuts against the bottom wall of the coal sample container 100;

[0064] S3, driving the locking disk 11 and the cleaning brush 21 to rotate, and driving the blower mechanism to blow hot air into the inner cavity of the coal sample container 100 to clean the coal sample container 100.

[0065] Specifically, step S1 includes:

[0066] S11. Place the coal sample container 100 with its mouth facing downward on a plurality of first limiting rods 121, and insert the second limiting rods 122 into the coal sample container 100. The first detection component 6 detects in real time whether a coal sample container 100 is placed on the locking disk 11. If so, the identifier identifies the specifications of the coal sample container 100 to determine the caliber and depth of the coal sample container 100.

[0067] S12, the controller sends a signal to the locking drive 13, and when the output end of the locking drive 13 is extended to the corresponding travel switch, it stops extending, so that the second limit rod 122 is limitedly abutted against the inner wall of the coal sample container 100, thereby locking the coal sample container 100 on the locking disk 11.

[0068] In step S2, the controller sends a signal to the lifting drive 23 to drive the cleaning brush 21 to rise until the output end of the lifting drive 23 is extended to the travel switch position at the corresponding depth. At this time, the cleaning brush 21 stops rising, and the bristles 212 on the top of the cleaning brush 21 abut against the bottom wall of the coal sample container 100.

[0069] In step S3, the rotating drive member 41 is started to drive the locking disk 11 to perform eccentric rotational motion, and the cleaning drive member 22 is started to drive the cleaning brush 21 to rotate, and the air outlet mechanism is started at the same time, so that the hot air generated by the air blowing mechanism is blown into the coal sample container 100 through the air holes 213 on the mounting cylinder 211, thereby cleaning the coal sample container 100; during the cleaning process, the second detection member 7 detects the rotation speed of the locking disk 11 in real time and feeds back to the controller, so as to determine whether the cleaning frequency meets the cleaning requirements, so as to adjust the rotation speed of the locking disk 11 and the cleaning brush 21 in time.
