[0030] The utility model discloses a granulating device for straw processing, which is mainly used in the scenario where the whole straw crushing and granulating efficiency is low.
[0031] Reference Figure 1-Figure 6A granulating device for straw processing comprises a base 1, a granulating cylinder 2 is fixedly arranged on the upper surface of the base 1, a horizontally distributed upper cylinder 3 is connected to the upper end of the granulating cylinder 2, and the straw inserted into the upper cylinder 3 is automatically transported to the granulating cylinder 2, a grinding disc 10 is fixed inside the granulating cylinder 2, a second motor 6 is fixedly arranged on one side of the base 1, and the output end of the second motor 6 drives the grinding wheel 13 on the surface of the grinding disc 10 to rotate through a gear set, and the grinding wheel 13 cooperates with the grinding disc 10 to crush the straw and squeeze it downward from the hole groove on the surface of the grinding disc 10; a vertical crushing knife 15 is arranged above the grinding wheel 13, and the vertical crushing knife 15 can be synchronously driven to rotate during the rotation of the grinding wheel 13, and the inner wall of the granulating cylinder 2 is fixed There is a connecting frame 21, a connecting rod 14 is rotatably arranged in the middle of the connecting frame 21, and vertical crushing knives 15 are evenly distributed on the outer surface of the connecting rod 14; a horizontal crushing knife 5 is rotatably arranged inside the upper barrel 3, and the horizontal crushing knife 5 is used to crush the straw entering from the upper barrel 3, and move the preliminarily crushed straw downward to the vertical crushing knife 15 for further crushing; a cutting knife 16 is arranged below the grinding disc 10, which is used to pelletize the material extruded from the hole groove, a quick-release mechanism 17 is movably arranged on the outer surface of the granulating barrel 2, one end of the upper barrel 3 is fixedly connected to the first motor 4, the output end of the first motor 4 is fixedly connected to the horizontal crushing knife 5, and a discharge chute 19 is arranged at the bottom of the granulating barrel 2.
[0032] In this embodiment, the whole straw is first inserted horizontally into the upper barrel 3, and the horizontal crushing knife 5 inside the upper barrel 3 will be driven to rotate by the first motor 4, so as to perform preliminary crushing on the straw, and the crushed straw will fall downward into the granulation barrel 2, and will be further crushed by the vertical crushing knife 15, so as to ensure the subsequent granulation effect, and the crushed straw will fall on the surface of the grinding disc 10, and as the second motor 6 drives the grinding wheel 13 to rotate, the straw will be squeezed and matured, and squeezed downward from the holes on the surface of the grinding disc 10, and at the same time, it will be granulated with the cutting knife 16 below. In this process, the grinding wheel 13 and the vertical crushing knife 15 rotate synchronously, which can improve the crushing efficiency and granulation efficiency while saving costs, and the overall structure of the equipment is compact and reasonable.
[0033] Specifically, Figure 1 As shown, the other end of the upper barrel 3 is a trumpet-shaped opening, which is convenient for personnel to stuff the whole straw into the upper barrel 3. A number of groups of conveying rollers are arranged on the inner wall of the upper barrel 3. The automatic feeding operation can be realized by the rotation of the conveying rollers, and there is no need for manual continuous feeding. The conveying rollers can be rotated by the motor at one end thereof, and a number of groups of conveying rollers rotate toward the inside of the upper barrel 3, thereby transporting the straw inserted into the upper barrel 3 inward and crushing it by the horizontal crushing knife 5.
[0034] Among them, the grinding wheel 13 can be automatically raised and lowered. The grinding wheel 13 rises to the lower surface of the connecting frame 21, and can contact the brush 23 on the lower surface of the connecting frame 21 to clean impurities. In the process of rotating granulation of the grinding wheel 13, the grinding wheel 13 can first rise and then fall, so that the crushed straw can be fully located on the surface of the grinding disc 10 to ensure the grinding and granulation effect. After the granulation is completed, the grinding wheel 13 can be raised to the lower surface of the connecting frame 21. Since the lower surface of the connecting frame 21 is provided with a brush 23, the impurities adhered to the outer surface of the grinding wheel 13 can be cleaned by the brush 23 by continuing to rotate the grinding wheel 13, thereby ensuring the subsequent granulation effect. The reason why impurities adhere to the grinding wheel 13 is mainly that it has not been cleaned for a long time or that materials with high moisture content are processed.
[0035] Among them, the quick-release mechanism 17 is used to remove the cutter 16 from the granulation barrel 2. The removed cutter 16 can be used to clean the straw blocked on the vertical crushing knife 15 and the horizontal crushing knife 5.

[0036] In this embodiment, the cutter 16 can be disassembled. If material is stuck in the gap between the vertical crushing knife 15 and the horizontal crushing knife 5 or material is blocked inside the granulating barrel 2, the inspection door 18 can be opened and the stuck straw can be hooked out through the hook structure at the end of the cutter 16, thereby improving the convenience of equipment maintenance and facilitating the maintenance of the cutter 16.
[0037] Specifically, Figure 3-Figure 8 The quick-release mechanism 17 includes a slot 1701 opened on the outer surface of the granulating cylinder 2, a fixed block 1702 is clamped at the slot 1701, and two groups of limit blocks 1703 are elastically connected inside the fixed block 1702. The clamping relationship between the fixed block 1702 and the slot 1701 can be released by pinching the two groups of limit blocks 1703 with fingers. A cutter 16 is fixed on the side of the fixed block 1702 close to the sleeve rod 9. The two groups of limit blocks 1703 are connected by a spring 1704. A pressing block 1705 is fixed to one end of the limit block 1703, and a clamping block 1706 is fixed to the other end of the limit block 1703.
[0038] In the present embodiment, during the process of disassembling the cutter 16, the pressing blocks 1705 of the two sets of limit blocks 1703 are pinched by fingers, so that the card block 1706 contracts inward, thereby disengaging from the card slot 1701, and then the cutter 16 can be pulled outward. If it needs to be installed, just release the fingers and allow the card block 1706 to be elastically reset and snapped into the card slot 1701 by the spring 1704.

[0040] In this embodiment, the second motor 6 can drive the active bevel gear 7 and the driven bevel gear 8 to rotate, so that the sleeve rod 9 and the grinding wheel 13 fixed to the driven bevel gear 8 rotate, thereby extruding and granulating the straw, and the sleeve rod 9 will drive the lifting rod 20, the telescopic rod 22 and the vertical crushing knife 15 to perform a rotational crushing operation, so that the crushing and granulation are carried out simultaneously, thereby improving the processing efficiency and saving costs, and the third motor 11 inside the sleeve rod 9 can drive the threaded rod 12 to rotate, thereby driving the lifting rod 20 on its outer surface to rise, and then the grinding wheel 13 at its upper end rises and contacts with the brush 23.
[0041] Specifically, the outer surfaces of the telescopic rod 22 and the lifting rod 20 are both provided with limiting strips 24, and the inner walls of the sleeve rod 9 and the lifting rod 20 are both provided with limiting grooves 25. The telescopic rod 22 cooperates with the limiting grooves 25 on the inner wall of the lifting rod 20 through the limiting strips 24, and the lifting rod 20 cooperates with the limiting grooves 25 on the inner wall of the sleeve rod 9 through the limiting strips 24, so as to ensure that the sleeve rod 9 can drive the lifting rod 20, the telescopic rod 22 and the vertical crushing knife 15 to rotate together while rotating, and will not affect the lifting and lowering of the grinding wheel 13.
[0042] The driven bevel gear 8 is rotatably connected to the top of the base 1, and the vertical crushing blades 15 are staggered along the vertical direction, which can effectively improve the crushing effect.
