[0033] When in use, the material-discharging shaft 10 is driven to rotate by the driving motor 38, so that the multiple material-discharging hook plates 11 fixedly installed on the outer surface of the material-discharging shaft 10 rotate, so that the material-discharging hook plates 11 pass through the strip opening opened at the bottom of the feed hopper 3 and hook part of the straw into the feeding hopper 2, so that the first conveyor belt 8 in the feeding hopper 2 conveys the hooked part of the straw in the direction of the crushing cover 4.

[0035] When the material-discharging shaft 10 rotates, the rotating rod 16 will be driven to rotate through the first pulley 18 and the first belt 19, so that the multiple eccentric wheels 17 fixedly installed on the outer surface of the rotating rod 16 can rotate accordingly, so that the eccentric wheel 17 cooperates with the multiple tension spring rods 14 to continuously push the push plate 15 to move downward, so that the push plate 15 can push the straw in the feed hopper 3 downward, to prevent the straw from getting stuck in the feed hopper 3 and affecting the feeding effect of the straw.

[0036] In this embodiment, the tensioning assembly includes a first thrust spring rod 20 fixedly mounted on the outer surface of the feed hopper 3, and a tensioning wheel 21 is rotatably mounted on the telescopic end of the first thrust spring rod 20, and the tensioning wheel 21 is against the inner side of the first belt 19.

[0037] When in use, the telescopic end of the first thrust spring rod 20 will push the tensioning wheel 21 to always press against the inner side of the first belt 19 to tension the first belt 19 so as to ensure the transmission effect between the two first pulleys 18 and the first belt 19 when the portal frame 13 moves up and down.

[0038] In this embodiment, the lifting mechanism includes a rotating column 22 that passes through and is rotatably installed between the top and bottom ends of the guide frame 39. The outer surface of the rotating column 22 is provided with a spiral groove 23. The rotating column 22 passes through the outer surface of the lifting block 12 and is slidably installed therewith. The upper surface of the lifting block 12 near the rotating column 22 is provided with a mounting groove 24. A second thrust spring rod 25 is fixedly installed inside the mounting groove 24. A connecting block 26 is fixedly installed at the telescopic end of the second thrust spring rod 25. A guide column 27 matching the spiral groove 23 is fixedly installed at one end of the connecting block 26 away from the second thrust spring rod 25. The guide column 27 is slidably installed on the inner wall of the spiral groove 23. A transmission mechanism is installed between the rotating column 22 and the material-dispensing shaft 10. An unlocking mechanism is installed on the lifting block 12. The transmission mechanism includes a driven bevel gear 33 fixedly installed at the bottom end of the rotating column 22. A transmission shaft 34 is rotatably installed on the outer surface of the feeding hopper 2. An active bevel gear 35 meshing with the driven bevel gear 33 is fixedly installed at one end of the transmission shaft 34. The same end of the material-dispensing shaft 10 is fixedly mounted with a second pulley 36, and the outer surfaces of the two second pulleys 36 are sleeved with a second belt 37. The unlocking mechanism includes a damping slider 29 which can be slidably mounted on the inner wall of the mounting groove 24. A spring is mounted on the outer side of the damping slider 29. The surface of the spring has a rubber layer, which can increase the friction between the damping slider 29 and the inner wall of the mounting groove 24, so that the damping slider 29 can stop at any position in the mounting groove 24. The length of the damping slider 29 is greater than the thickness of the lifting block 12. Degree; a trapezoidal groove 30 is provided on the outer surface of the damping slider 29 near the connecting block 26, and a lever 28 is fixedly installed on the outer surface of the connecting block 26 near the damping slider 29. The outer periphery of the lever 28 is in contact with the inner wall of the trapezoidal groove 30, and a baffle 31 is fixedly installed on the inner wall of the guide frame 39 near its bottom. A plurality of third thrust spring rods 32 are fixedly installed on the lower surface of the baffle 31, and the telescopic ends of the plurality of third thrust spring rods 32 pass through the upper surface of the baffle 31 and are fixedly installed on the lower surface of the lifting block 12.

[0039] When the material-dispensing shaft 10 rotates, the transmission shaft 34 will be driven to rotate through the second pulley 36 and the second belt 37, so that the active bevel gear 35 installed at the end of the transmission shaft 34 drives the driven bevel gear 33 meshing with it to rotate, so that the driven bevel gear 33 drives the rotating column 22 to rotate. In the initial state, since the guide column 27 is inserted into the spiral groove 23 opened on the outer surface of the rotating column 22 by the elastic force of the second thrust spring rod 25, the rotating column 22 can drive the lifting block 12 to move downward through the spiral groove 23 and the guide column 27 when rotating, so that the lifting block 12 can drive the door frame 13 to move downward slowly as a whole, so that as the straw in the feed hopper 3 decreases, the height of the push plate 15 is reduced, so that the push plate 15 can always push the straw in the feed hopper 3; when the lifting block 12 drops to the lowest point, the bottom end of the damping slider 29 installed in the mounting groove 24 that slides up and down will abut against the upper surface of the baffle plate 31, so that the baffle plate 3 1 can push the damping slider 29 upward, so that the damping slider 29 pushes the lever 28 toward the direction of the second thrust spring rod 25 through the oblique side of the trapezoidal groove 30 opened on its side, so that the lever 28 can drive the connecting block 26 and the guide column 27 to retract into the installation groove 24, so that the guide column 27 is pulled out from the spiral groove 23. At this time, there is no axial constraint between the lifting block 12 and the rotating column 22, so that the lifting block 12 is pushed upward under the elastic force of the plurality of third thrust spring rods 32 and returns to the initial position; after the lifting block 12 rises to the top, the top of the damping slider 29 will abut against the top of the guide frame 39, so that the damping slider 29 is pushed downward, so that the lever 28 can be pushed into the trapezoidal groove 30 opened on the side of the damping slider 29 under the action of the second thrust spring rod 25, so that when the rotating column 22 rotates later, the guide column 27 can be inserted into the spiral groove 23 again, and the lifting block 12 and the door frame 13 are repeatedly driven to move downward as a whole.

[0040] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the bundled and unpacked straw is put into the feed hopper 3, and the driving motor 38 drives the material-dispensing shaft 10 to rotate, so that the multiple material-dispensing hook plates 11 fixedly installed on the outer surface of the material-dispensing shaft 10 rotate, so that the material-dispensing hook plates 11 pass through the strip opening opened at the bottom of the feed hopper 3 and hook part of the straw into the feeding hopper 2, so that the first conveyor belt 8 in the feeding hopper 2 conveys the hooked part of the straw in the direction of the crushing cover 4, and the second conveyor belt 9 and the first conveyor belt 8 are used in coordination, so that a certain clamping force can be applied to both the upper and lower sides of the straw, so that the straw can be better fed into the crushing cover 4, and the stability of the straw transportation is ensured;

[0041] After the straw is fed into the crushing cover 4, the crushing motor 6 will drive the crushing blade shaft 7 to rotate at a high speed, so that the high-speed rotating crushing blade shaft 7 can crush the straw, and the crushed straw particles will be discharged downward through the discharge hopper 5 so that the straw particles can be received and collected;

[0042] When the material-dispensing shaft 10 rotates, the first pulley 18 and the first belt 19 drive the rotating rod 16 to rotate, so that the multiple eccentric wheels 17 fixedly installed on the outer surface of the rotating rod 16 can rotate accordingly, so that the eccentric wheels 17 cooperate with the multiple tension spring rods 14 to continuously push the push plate 15 to move downward, so that the push plate 15 can push the straw in the feed hopper 3 downward to prevent the straw from being stuck in the feed hopper 3 and affecting the feeding effect of the straw;

[0043] When the material-dispensing shaft 10 rotates, the transmission shaft 34 will be driven to rotate through the second pulley 36 and the second belt 37, so that the active bevel gear 35 installed at the end of the transmission shaft 34 drives the driven bevel gear 33 meshing with it to rotate, so that the driven bevel gear 33 drives the rotating column 22 to rotate. In the initial state, the guide column 27 is inserted into the spiral groove 23 opened on the outer surface of the rotating column 22 by the elastic force of the second thrust spring rod 25, so that the rotating column 22 can drive the lifting block 12 to move downward through the spiral groove 23 and the guide column 27 when rotating, so that the lifting block 12 can drive the portal frame 13 to move downward slowly as a whole, so that as the straw in the feed hopper 3 decreases, the height of the push plate 15 is reduced, so that the push plate 15 can always push the straw in the feed hopper 3;

[0044] When the lifting block 12 descends to the lowest point, the bottom end of the damping slider 29 installed in the mounting groove 24 by sliding up and down will abut against the upper surface of the baffle 31, so that the baffle 31 can push the damping slider 29 upward, so that the damping slider 29 pushes the lever 28 toward the direction of the second thrust spring rod 25 through the oblique side of the trapezoidal groove 30 opened on its side, so that the lever 28 can drive the connecting block 26 and the guide column 27 to retract into the mounting groove 24, so that the guide column 27 is pulled out of the spiral groove 23. At this time, there is no longer an axial constraint between the lifting block 12 and the rotating column 22, so that the lifting block 12 is pushed upward under the elastic force of the multiple third thrust spring rods 32 and returns to the initial position.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
