[0020] Further in the present invention; a coal blending method of intelligent coal blending equipment comprises the following steps:

[0021] Step 1: Load the coal from the processing box, and turn on the stepper motor to drive the driving rod to rotate. At this time, the crushing teeth staggered on the surface of the driving rod will crush the coal so that the coal can be quickly discharged from the discharge port, ensuring the loading efficiency, improving the work quality, preventing large pieces of coal from getting stuck, and ensuring the stability of the equipment;

[0022] Step 2: The crushed coal falls on the surface of the screen plate inside the sealing cover. At this time, the servo motor is turned on to drive the swing arm to rotate. The swing arm rotates and abuts against the surface of the screen plate to force it to move down along the fixed rod. At the same time, the limit spring is compressed. When the swing arm is separated from the surface of the screen plate, the limit spring is reset to make the screen plate vibrate, so as to quickly screen and discharge the coal, ensure the coal blending efficiency, and improve the work quality; when it is necessary to screen coal of different fineness, the screen plate can be replaced, and the anti-slip pad is pressed to make the push rod move under force. At the same time, the movable rod slides along the guide rod and compresses the positioning spring. At this time, the positioning block is collected in the interior of the positioning plug and is no longer clamped in the interior of the fixed rod. Then the positioning seat can be removed. After all the positioning seats are disassembled in turn, the screen plate can be replaced to ensure the convenience of disassembly and assembly of the screen plate and improve the use efficiency of the equipment;

[0023] Step 3: The screened coal falls into the upper ends of the conveyor belts inside the upper collecting rack and the lower collecting rack respectively, and then the driving motor is started to drive the conveyor belt to carry out feeding work. The coal is sent along the conveyor belt to the inside of the collecting box for collection. When the driving motor is working, it will drive the push rod to rotate, and the push rod abuts against one side of the matching block to make the collecting box move under force. At the same time, the T-shaped slider at the upper end of the collecting box abuts against one side of the abutting block and compresses the return spring. When the push rod is separated from the matching block, the return spring resets and pushes the T-shaped slider to move. At this time, the collecting box is forced to swing so as to spread the coal collected inside it evenly, prevent coal accumulation from affecting the collection effect, and improve the loading quality; when the collecting box needs to be removed for use, the trapezoidal stopper is moved upward to make the connecting rod move along the inside of the fixed plate. At this time, the telescopic spring is compressed and the trapezoidal stopper no longer limits the T-shaped slider. Then the T-shaped slider can be slid along the T-shaped slide groove to remove the collecting box for use, thereby improving the convenience of equipment use and saving human resources.

[0024] Step 4: When collecting coal, the exhaust fan can be started to extract air. The dust generated by coal unloading is blocked by the dust shield. At the same time, the airflow sucks the dust into the filter rack inside the installation box for filtration and collection, preventing dust from harming human health, improving the safety of equipment use, and ensuring work quality; when it is necessary to clean the filter rack, pull the limit rod to move the card frame and detach it from the inside of the limit frame. At this time, the tension spring is stretched by force, and then the two sets of card frames are taken out at the same time and the upper cover is moved upward to remove the filter rack from the inside of the installation box, ensuring the convenience of disassembly and cleaning of the filter rack, improving the filtering effect, and ensuring the quality of dust reduction.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention can crush the coal by setting a feed processing component so that the coal can be quickly discharged from the discharge port, thereby ensuring the feeding efficiency, improving the work quality, preventing large pieces of coal from getting stuck, and ensuring the stability of the equipment operation.

[0027] 2. The present invention provides a filtering and screening component, which can vibrate the screen plate to quickly screen and discharge the coal, thereby ensuring the coal blending efficiency, improving work quality, saving human resources, and conveniently replacing screen plates of different specifications for use, thereby improving the applicability of the equipment, improving the disassembly and assembly efficiency, and saving human resources.

[0028] 3. The present invention provides a convenient dust reduction component. The dust generated by coal feeding is shielded by the dust shield. The exhaust fan is started to suck the dust into the filter frame inside the installation box for filtration and collection, thereby preventing dust from harming human health, improving the safety of equipment use, and ensuring work quality. The filter frame is easy to disassemble and clean, thereby improving the filtering effect and ensuring the dust reduction quality.

[0029] 4. The present invention provides a swinging and evenly spreading component, in which the collection box is driven by a push rod to swing, so as to spread the coal collected inside evenly, prevent coal accumulation from affecting the collection effect, improve the loading quality, and conveniently remove the collection box to take out the coal. The equipment is easy to use and saves human resources. BRIEF DESCRIPTION OF THE DRAWINGS

When the driving motor 52 is working, it will drive the push rod 54 to rotate, and the push rod 54 abuts against one side of the matching block 55 to make the collecting box 56 move under force. At the same time, the T-shaped slider 536 at the upper end of the collecting box 56 abuts against one side of the abutting block 57 and makes the reset spring 58 compressed under force. When the push rod 54 is separated from the matching block 55, the reset spring 58 resets and pushes the T-shaped slider 536 to move.

[0065] By adopting the above technical solution, when the collection box 56 needs to be removed for use, the trapezoidal stop block 534 is moved upward to allow the connecting rod 532 to move along the inside of the fixed plate 531. At this time, the telescopic spring 533 is compressed and the trapezoidal stop block 534 no longer limits the T-shaped slider 536. Then, the T-shaped slider 536 can be slid along the T-shaped slide groove 535 to remove the collection box 56 for use, thereby improving the convenience of equipment use and saving human resources.

[0066] When the present embodiment is in use, the screened coal falls into the upper ends of the conveyor belts 6 inside the upper collecting rack 7 and the lower collecting rack 8 respectively, and then the driving motor 52 is started to drive the conveyor belt 6 to perform feeding work, and the coal is sent to the inside of the collecting box 56 along the conveyor belt 6 for collection. When the driving motor 52 is working, it will drive the push rod 54 to rotate, and the push rod 54 abuts against one side of the matching block 55 so that the collecting box 56 is forced to move.

When the push rod 54 is separated from the matching block 55, the return spring 58 is reset to push the T-shaped slider 536 to move. At this time, the collecting box 56 is forced to swing so as to spread the coal collected inside it evenly, prevent coal accumulation from affecting the collection effect, and improve the loading quality.

[0067] When the collection box 56 needs to be removed for use, the trapezoidal stop block 534 is moved upward to allow the connecting rod 532 to move along the inside of the fixed plate 531. At this time, the telescopic spring 533 is compressed and the trapezoidal stop block 534 no longer limits the T-shaped slider 536. Then the T-shaped slider 536 can be slid along the T-shaped slide groove 535 to remove the collection box 56 for use, thereby improving the convenience of equipment use and saving human resources.

[0068] The structure and use principle of the side baffle 1, conveyor belt 6, upper collecting rack 7 and lower collecting rack 8 in the present invention have been disclosed in an automatic coal blending equipment for coal mines disclosed in Chinese patent application No. 202323048630.X.

[0069] Working principle and use process of the present invention: When the present invention is used, the coal is loaded from the processing box 32, and the stepper motor 35 is turned on to drive the driving rod 33 to rotate. At this time, the crushing teeth 34 staggered on the surface of the driving rod 33 will crush the coal so that the coal can be quickly discharged from the discharge port 31, thereby ensuring the loading efficiency, improving the work quality, preventing large pieces of coal from getting stuck, and ensuring the stability of the equipment operation;

[0070] The crushed coal falls on the surface of the sieve plate 24 inside the sealing cover 21. At this time, the servo motor 27 is turned on to drive the swing rod 26 to rotate. The swing rod 26 rotates and abuts against the surface of the sieve plate 24 to force it to move down along the fixed rod 22. At the same time, the limit spring 25 is compressed. When the swing rod 26 is separated from the surface of the sieve plate 24, the limit spring 25 is reset to make the sieve plate 24 vibrate, so as to quickly screen and discharge the coal, ensure the coal blending efficiency, and improve the work quality.

[0071] When it is necessary to screen coal of different fineness, the sieve plate 24 can be replaced, and the anti-slip pad 234 is pressed to make the push rod 238 move under force, and at the same time, the movable rod 235 slides along the guide rod 237 and compresses the positioning spring 236. At this time, the positioning block 233 is retracted into the interior of the positioning plug rod 231 and is no longer clamped in the interior of the fixed rod 22. Then the positioning seat 232 can be removed, and the sieve plate 24 can be replaced after all the positioning seats 232 are disassembled in turn, so as to ensure the convenience of disassembly and assembly of the sieve plate 24 and improve the use efficiency of the equipment;

[0072] The screened coal falls into the upper ends of the conveyor belts 6 inside the upper collecting rack 7 and the lower collecting rack 8 respectively, and then the driving motor 52 is started to drive the conveyor belt 6 to perform feeding work, and the coal is sent to the inside of the collecting box 56 along the conveyor belt 6 for collection. When the driving motor 52 is working, it will drive the push rod 54 to rotate, and the push rod 54 abuts against one side of the matching block 55 to make the collecting box 56 move under force. At the same time, the T-shaped slider 536 at the upper end of the collecting box 56 abuts against one side of the abutting block 57 and compresses the reset spring 58. When the push rod 54 is separated from the matching block 55, the reset spring 58 resets and pushes the T-shaped slider 536 to move. At this time, the collecting box 56 is forced to swing so as to spread the coal collected inside it evenly, prevent coal accumulation from affecting the collection effect, and improve the loading quality.

[0073] When the collection box 56 needs to be removed for use, the trapezoidal stopper 534 is moved upward to allow the connecting rod 532 to move along the inside of the fixed plate 531. At this time, the telescopic spring 533 is compressed and the trapezoidal stopper 534 no longer limits the T-shaped slider 536. Then, the T-shaped slider 536 can be slid along the T-shaped slide groove 535 to remove the collection box 56 for use, thereby improving the convenience of equipment use and saving human resources.

[0074] When collecting coal, the exhaust fan 44 can be started to extract air, and the dust generated by coal feeding is shielded by the dust shield 46. At the same time, the airflow sucks the dust into the filter rack 42 inside the installation box 45 for filtration and collection, so as to prevent dust from harming human health, improve the safety of equipment use, and ensure the work quality;

[0075] When it is necessary to clean the filter rack 42, pull the limit rod 432 to make the clamping frame 433 move and disengage from the inside of the limit rack 434. At this time, the tension spring 431 is stretched by the force, and then the two sets of clamping frames 433 are taken out at the same time and the upper cover 41 is moved upward to remove the filter rack 42 from the inside of the installation box 45, thereby ensuring the convenience of disassembly and cleaning of the filter rack 42, improving the filtering effect, and ensuring the dust reduction quality.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
