Description

Technical Field

[0001] This utility model relates to the field of mechanization technology, specifically to a connection mechanism between a crusher blade and a cutter shaft. Background Technology

[0002] The connection mechanism between the crusher blades and the cutter shaft is a crucial core component in crushing equipment, and its design directly determines the equipment's cutting efficiency, operational stability, and subsequent maintenance costs. A scientifically designed connection mechanism not only significantly improves the crusher's efficiency during the cutting process, ensuring that materials are crushed quickly and uniformly, but also effectively guarantees the stability of the equipment under long-term high-load operation, reducing the failure rate caused by vibration or wear. Furthermore, an optimized connection mechanism design can reduce maintenance costs, making blade replacement and maintenance more convenient and efficient, thereby extending the equipment's service life and improving overall economic benefits. Therefore, careful design and continuous improvement of the crusher blade-cutter shaft connection mechanism are key to enhancing the overall performance of crushing equipment.

[0003] For example, patent number CN210580050U relates to a wheat straw crusher, including a box-type casing and a crushing mechanism. One end of the box-type casing is connected to the straw discharge port of a wheat harvester, and the other end has a discharge port. The crushing mechanism includes a main rotating blade and a secondary rotating blade. The main rotating blade uses 8-12 sets of blades fixed on a main rotating blade shaft, and the secondary rotating blade uses circular saw-type blades fixed on a secondary rotating blade shaft, with each circular saw-type blade corresponding to one set of blades from the main rotating blade. One end of the main rotating blade shaft is connected to the harvester's power wheel via a transmission wheel, and one end of the secondary rotating blade shaft is connected to the transmission wheel of the main rotating blade via a transmission wheel. Based on the existing structure of wheat crushers, the fixed blade is designed as a rotating sawtooth disc. The crushing blade shaft and the passive blade shaft rotate, and the overlapping parts of the blades move in opposite directions, changing the original passive waiting and interception of the fixed blade to active rotation and cutting, resulting in higher working efficiency and better crushing effect.

[0004] For example, patent number [number missing] provides a medicinal herb pulverizer, belonging to the field of pulverizer technology. This medicinal herb pulverizer includes a housing and a pulverizing mechanism. The pulverizing mechanism includes a motor, which is fixedly connected to the front of the housing; a drive shaft is fixedly connected to the output end of the motor; a first blade is fixedly connected to the outer wall of the drive shaft and is disposed inside the housing; a main gear is fixedly connected to the outer wall of the drive shaft, the main gear meshes with a driven gear, the driven gear is fixedly connected to a driven shaft, and a second blade is fixedly connected to the outer wall of the driven shaft. When the motor is started, the output end of the motor drives the drive shaft to rotate, the drive shaft drives the main gear to rotate, the main gear drives the driven gear to rotate, the driven gear drives the driven shaft to rotate, and thus drives the first and second blades to rotate, thereby pulverizing the medicinal herbs. The cooperation of the first and second blades ensures more thorough pulverization of the medicinal herbs, guaranteeing their subsequent usability.

[0005] A wheat straw crusher and a medicinal herb crusher both use rotating blades for crushing. While these methods are effective, both machines employ a rotating blade and shaft design. This design results in a large moment of inertia and slow start-up and braking because the blade and shaft rotate together. Furthermore, the torque generated during crushing directly impacts the shaft, reducing its lifespan. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a connection mechanism between a crusher blade and a cutter shaft, comprising a rotating shaft 1 and a housing 2. The housing 2 is mainly composed of an outer shell 201. A recovery motor 202 is installed inside the outer shell 201. The recovery motor 202 is equipped with an active recovery pulley 203. A recovery belt 220 is installed on the active recovery pulley 203. A driven recovery pulley 204 is installed at the other end of the recovery belt 220. The driven recovery pulley 204 is mounted on a recovery crossbar 205. The recovery crossbar 205 is positioned on the left... A swing arm 206 is provided at both ends of the right side. The other end of the swing arm 206 is connected to a push rod 207. The other end of the push rod 207 is connected to the slider 11. The two ends of the recovery crossbar 205 are installed at the left and right ends of the outer casing 201. Belt compartments 215 are provided at the left and right ends of the outer casing 201. Driven pulleys 1218 are provided inside the belt compartments 215. Driven pulleys 1218 are installed at both ends of the transmission rod 208. A transmission belt 217 is installed on the driven pulleys 1218. A driven pulley 2216 is provided at the other end of the transmission belt 217. The driven pulley 2216 is connected to the gear shaft 214, and the gear shaft 214 is equipped with a transmission gear 213. The transmission gear 213 meshes with the rotating gear 12. A power motor 219 is installed inside the housing 201. The power motor 219 is connected to the power shaft 212, and the power shaft 212 is equipped with a driving power pulley 211. The driving power pulley 211 is equipped with a power belt 210, and the lower end of the power belt 210 is connected to a driven power pulley 209. The driven power pulley 209 is mounted on... On the transmission rod 208, both ends of the transmission rod 208 are mounted on the outer casing 201. The rotating shaft 1 is based on the cutter shaft 15. The cutter shaft 15 is provided with 13 blade holders 16. The blade holders 16 are equipped with 4 rotating rods 14. The rotating rods 14 are equipped with 13 blade holders. Each blade holder 16 is fixed to the rotating rod 14 by a fixing block 17. The rotating rods 14 are provided with connecting discs 13 and rotating gears 12 at both ends. The cutter shaft 15 is provided with sliders 11 at both ends. The blade holders 16 are equipped with 4 blade mounting brackets 18.

[0026] In use, the recycling motor 202 rotates clockwise, causing its driven recycling pulley 204 to rotate clockwise, which in turn drives the recycling crossbar 205 to rotate clockwise. The recycling crossbar 205 drives the swing arm 206 to rotate clockwise, and the swing arm 206 causes the push rod 207 to push the rotating shaft 1 to the bottom of the housing 2.

The rotating rods 14 drive the blade holder 16 to rotate. When the work is completed, the recycling motor 202 rotates counterclockwise to retract the rotating shaft 1 into the housing 2.

[0027] In summary, the connection mechanism between the shredder blades and the cutter shaft utilizes a retraction motor 202 to retract and lower the rotating shaft. A transmission gear 213 drives a rotating gear 12, which in turn drives four rotating rods 14 to rotate around the cutter shaft 15. This achieves asynchronous rotation of the blade holder 16 and the cutter shaft 15, extending the lifespan of the cutter shaft, reducing its moment of inertia, and enabling faster start-up and braking. This mechanism allows the rotating shaft to be retracted, effectively reducing space occupation when the equipment is idle or requires transportation or maintenance. Furthermore, this retractable design prevents accidental collisions or damage to the blades when not in operation, further improving the equipment's safety and durability. When the equipment needs to be used again, the retraction motor is started in reverse, and the rotating shaft is unfolded to the working position in the opposite motion, allowing for rapid shredding operations.
