[0002] The coke sample crushing strength tester is primarily used to determine the crushing strength of coke, a key indicator of coke quality. Crushing strength reflects the coke's ability to resist breakage when impacted and is crucial to its performance during the blast furnace smelting process.
[0003] Existing coke sample crushing strength testing devices require placing the sample to be tested on a press plate. A hydraulic cylinder is activated, which drives the press plate to compress the sample while simultaneously displaying the monitored value on a control panel. After the test, coke residue adheres to the press plate, requiring manual cleaning, which can easily contaminate the operator's hands and reduce their comfort when using the equipment. Therefore, we propose a coke sample crushing strength testing device. Utility Model Content

[0008] Wherein, both ends of the sliding rod are fixedly connected inside the protective cabinet.
[0009] The outer side of the sliding block is slidably connected to the inner wall of the shell.
[0010] The latch passes through the mounting block and is inserted into the brush, and one end of the latch away from the mounting block is fixedly connected with a pull column.
[0011] One end of the spring is fixedly connected to the inner wall of the shell, and the other end of the spring is fixedly connected to the outer side of the sliding block.
[0012] The utility model has at least the following beneficial effects:
[0013] When the utility model is in use, the glass protective door is opened, the sample is placed above the pressing platform, the glass protective door is closed, and the hydraulic cylinder is started through the control panel. The hydraulic cylinder pushes the pressing plate to extrude the sample, and the control panel displays the monitored data. By setting the cleaning mechanism, the motor is started, the motor drives the threaded rod to rotate, and the threaded rod drives the mounting block to move.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example 1
[0020] See also Figures 1 to 4 The utility model provides a technical solution: a coke sample crushing strength testing device, comprising: a cabinet body 1, a control panel 2 is provided on the outside of the cabinet body 1, a protective cabinet 3 is fixedly connected to the top of the cabinet body 1, a glass protective door 4 is hinged on the outside of the protective cabinet 3, a hydraulic cylinder 5 is fixedly connected to the inside of the top of the protective cabinet 3, and the output end of the hydraulic cylinder 5 is fixedly connected to a pressure plate 6, the inside of the bottom of the protective cabinet 3 is fixedly connected to a mounting column 7, and the top of the mounting column 7 is fixedly connected to a pressure platform 8. A cleaning mechanism 9 is provided inside the protective cabinet 3. When in use, the glass protective door 4 is opened, the sample is placed on the pressure platform 8, and the glass protective door 4 is closed. The hydraulic cylinder 5 is started through the control panel 2, and the hydraulic cylinder 5 pushes the pressure plate 6 to squeeze the sample. At the same time, the control panel 2 displays the monitored data. By setting the cleaning mechanism 9, the coke residue attached to the pressure plate 6 can be automatically cleaned, eliminating manual cleaning, preventing coke residue from contaminating the operator's hands, improving the operator's comfort in using the equipment, and the quick replacement of the brush 93 prevents the brush 93 from being used for a long time and the cleaning effect is reduced.
[0021] The cleaning mechanism 9 includes a motor 90, the output end of the motor 90 is fixedly connected to a threaded rod 91, the outer periphery of the threaded rod 91 is threadedly connected to a mounting block 92, the interior of the mounting block 92 is slidably connected to a brush 93, the interior of the mounting block 92 is slidably connected to a slide rod 94, the outer side of the mounting block 92 is fixedly connected to two shells 95, the interior of the shell 95 is slidably connected to a latch 96, the outer periphery of the latch 96 is sleeved with a spring 97, the outer periphery of the latch 96 is fixedly connected to a sliding block 98, and the bottom of the mounting block 92 is fixedly connected to a baffle 910. When in use, the hydraulic cylinder 5 is started to push the pressure plate 6 down to abut against the brush 93, and then the motor 90 is started. The motor 90 drives the threaded rod 91 to rotate, and the threaded rod 91 drives the mounting block 92 to move. The mounting block 92 moves on the periphery of the slide rod 94 and moves with the brush 93 at the same time. The brush 93 cleans the coke residue attached to the pressure plate 6 and the pressing platform 8. , the residue of the pressing plate 6 falls on the baffle 910, preventing the cleaned residue from falling on the broken sample on the surface of the pressing platform 8 and interfering with the test personnel's observation of the sample. Pull the pull column 99, and the pull column 99 drives the latch 96. The latch 96 slides out from the inside of the brush 93 and the mounting block 92 to slide inside the shell 95. At the same time, the latch 96 drives the sliding block 98 to slide inside the shell 95. When the sliding block 98 slides, the spring 97 is compressed, so that the spring 97 generates an elastic force. When the latch 96 slides out from the inside of the brush 93, the brush 93 can be taken out for replacement. When installing the brush 93, also pull the pull column 99 and place the brush 93 into the inside of the mounting block 92. Release the pull column 99, and the spring 97 pushes the sliding block 98. The sliding block 98 drives the latch 96 to insert into the inside of the brush 93. By controlling the forward and reverse rotation of the motor 90 to drive the threaded rod 91 to rotate, the brush 93 can be reset. Example 2
[0022] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the outer periphery of the threaded rod 91 rotates inside the protective cabinet 3, so that the threaded rod 91 rotates stably and prevents dust from adhering to the surface of the threaded rod 91 and affecting its service life. Both ends of the sliding rod 94 are fixed inside the protective cabinet 3. The sliding rod 94 can prevent the mounting block 92 from rotating with the threaded rod 91 and support the mounting block 92 to slide. The outer side of the sliding block 98 slides on the inner wall of the shell 95, so that the latch 96 can drive the sliding block 98 when it moves. The latch 96 passes through the mounting block 92 and is inserted into the brush 93, so that the brush 93 is stably installed and convenient to replace the brush 93. A pull column 99 is fixed on the end of the latch 96 away from the mounting block 92 to facilitate pulling the latch 96. One end of the spring 97 is fixed to the inner wall of the shell 95 and the other end is fixed to the outside of the sliding block 98, so that the spring 97 can be compressed by the sliding block 98 to provide elastic force.
