[0042] Among them, a discharging chamber 101 is opened inside the box body 1, a discharging port a104 is opened between the discharging chamber 101 and the crushing chamber 105, an electric telescopic rod 3 is arranged inside the box body 1, one end of the electric telescopic rod 3 extends into the discharging chamber 101 and is fixedly connected with a push block 301, two hydraulic chambers 103 are opened inside the box body 1, two lifting chambers 108 are opened inside the box body 1, and the two lifting chambers 108 are respectively communicated with the two hydraulic chambers 103, a storing chamber 109 is opened inside the box body 1, a discharging port b410 is opened on one side of the discharging block 4, a discharging chamber 401 is opened inside the discharging block 4, an electric push rod a402 is arranged on one side of the discharging block 4, a connecting pipe 404 is fixedly connected to one side of the discharging block 4, a connecting cover 405 is arranged on one side of the discharging block 4, a dust filter bag 407 is fixedly connected to one side of the connecting cover 405, and a cloth bag 406 is installed inside the dust filter bag 407.

[0043] When the crushing is completed, the electric telescopic rod 3 can be controlled to retract, thereby driving the push block 301 to move away from the discharging block 4 and opening the discharging port a104. At this time, the rice straw debris inside the crushing chamber 105 enters the discharging chamber 101 through the discharging port a104 and is located on one side of the push block 301. Then the electric telescopic rod 3 is controlled to extend to reset the push block 301, block the discharging port a104, and make the rice straw debris inside the discharging chamber 101 enter the discharging chamber 401 through the discharging port b410. Then the electric push rod a402 is controlled to extend to drive the push plate 403 to push the rice straw debris inside the discharging chamber 401 into the cloth bag 406 to collect the rice straw debris. At the same time, the dust filter bag 407 can be set to prevent rice powder from floating into the air when the rice straw debris is collected.

[0044] Among them, a limit cavity 102 is opened at the top of the inner wall of the discharge cavity 101, and a limit plate 2 is arranged inside the limit cavity 102. Two connecting rods 201 are fixedly connected to one side of the limit plate 2, and one end of the two connecting rods 201 is fixedly connected to an extrusion piston 202.

[0052] When in use, the operator can spread the rice straw to be crushed on the top of the stone filter net 505, and turn on the two servo motors a501, and rotate the rotating wheel 503 through the two servo motors a501, so that the multiple knocking rods 504 intermittently hit the stone filter net 505, and then the stone filter net 505 vibrates, so that the stones or soil stuck in the rice straw are shaken off and fall into the bottom of the inner wall of the stone screening box 5 through the mesh on the stone filter net 505. When the stones or soil are shaken off, the two servo motors a501 can be turned off to stop the knocking rods 504 from hitting the stone filter net 505, and then the two servo motors a506 can be turned on. , two servo motors a506 rotate two threaded screws 507, thereby driving the scraper 509 to leave the placement groove 508 and move toward the direction close to the two servo motors a506, so as to push the rice straw on the top of the stone filter net 505 to the installation groove 9, and then make the rice straw fall from the installation groove 9 into the inside of the mobile platform 8, and finally, the threaded screw 507 is reversed by the two servo motors a506, thereby driving the scraper 509 to reset, and then the next batch of rice straw can be processed. In addition, a slot is opened on one side of the stone screening box 5, and the operator can clear the screened stones and soil from the stone screening box 5 through this slot.

[0053] Here’s how it works: When in use, the operator can spread the rice straw to be crushed on the top of the stone filter net 505, and turn on the two servo motors a501, and rotate the rotating wheel 503 through the two servo motors a501, so that the multiple knocking rods 504 intermittently hit the stone filter net 505, and then the stone filter net 505 vibrates, so that the stones or soil stuck in the rice straw are shaken off and fall into the bottom of the inner wall of the stone screening box 5 through the mesh on the stone filter net 505. When the stones or soil are shaken off, the two servo motors a501 can be turned off to stop the knocking rods 504 from hitting the stone filter net 505, and then the two servo motors a506 can be turned on. , two servo motors a506 rotate two threaded screws 507, thereby driving the scraper 509 to leave the placement groove 508 and move toward the direction close to the two servo motors a506, so as to push the rice straw on the top of the stone filter net 505 to the installation groove 9, and then make the rice straw fall from the installation groove 9 into the inside of the mobile platform 8, and finally, the threaded screw 507 is reversed by the two servo motors a506, thereby driving the scraper 509 to reset, and then the next batch of rice straw can be processed. In addition, a slot is opened on one side of the stone screening box 5, and the operator can clear the screened stones and soil from the stone screening box 5 through this slot.

[0054] Furthermore, after screening out the stones and soil, the rice straw inside the mobile platform 8 can be taken out, put into the feed trough 605, and placed on one side of the feed push block 602, and then the two servo motors b601 are turned on, and the two screws 606 are rotated by the two servo motors b601, thereby driving the slider 607 and the feed push block 602 to move towards the box body 1, and then pushing the rice straw to the bottom of the bracket 7, and then controlling the electric push rod b703 to extend, drive the cutting knife 702 and the two knife seats 701 to move downward, and cut the rice straw, and then control the electric push rod b703 to retract, so that the cutting knife 702 is reset, and the two servo motors b601 are turned on again, driving the feed push block 602 to push the rice straw into the crushing chamber 105, and at the same time, turn on the two motors 107 and rotate the two crushing rollers 106 to crush the rice straw.

[0055] Then, the crushed rice straw debris passes through the discharge port a104 and falls to the top of the push block 301. A transparent plastic plate is provided on one side of the box body 1, and the operator can observe whether the rice straw is crushed through the transparent plastic plate. When the crushing is completed, the electric telescopic rod 3 can be controlled to retract, thereby driving the push block 301 to move away from the discharge block 4 and opening the discharge port a104. At this time, the rice straw debris inside the crushing chamber 105 enters the discharge chamber 101 through the discharge port a104 and is located on one side of the push block 301. Then, the electric telescopic rod 3 is controlled to extend to reset the push block 301, block the discharge port a104, and allow the rice straw debris inside the discharge chamber 101 to enter the discharge chamber 401 through the discharge port b410. Then, the electric push rod a402 is controlled to extend to drive the push plate 403 to push the rice straw debris inside the discharge chamber 401 into the cloth bag 406 to collect the rice straw debris. At the same time, the dust filter bag 407 can be set to prevent rice powder from floating into the air when the rice straw debris is collected.

[0056] When the electric telescopic rod 3 controls the push block 301 to move away from the discharge block 4 and opens the discharge port a104, the push block 301 pushes the limit plate 2 and the connecting rod 201 to move toward the electric telescopic rod 3, so that the extrusion piston 202 squeezes the liquid inside the hydraulic chamber 103, and then pushes the piston 203 to rise along the lifting chamber 108 through the liquid, squeezes the spring 205, and drives the blocking plate 206 to rise, thereby blocking the crushing chamber 105 and preventing new rice straw from entering the crushing chamber 105, so that the equipment can start the next cycle of work after emptying the current batch of rice straw debris, so as to reduce unnecessary equipment downtime.
