Description

Technical Field

[0001] This utility model relates to the field of shredder technology, specifically a large-scale dual-shaft shredder. Background Technology

[0002] A large-scale twin-shaft shredder is a device that uses a twin-shaft structure for shredding materials. The twin shafts drive shredding blades to compress and shred the material. However, in existing twin-shaft shredders, some of the shredded material gets stuck on the shredding blades during operation, and material accumulates in the feeding mechanism, preventing the smooth discharge of the shredded material from the shredder and thus affecting its operational smoothness.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figure 1-6 This utility model provides a large dual-shaft shredder, including two mounting bases 1. Equipment boxes 2 are fixedly connected to the upper side walls of the two mounting bases 1. Motors 3 are fixedly connected inside the two equipment boxes 2. Gearboxes 4 are fixedly connected to the upper side of the two equipment boxes 2. The output shaft of the motor 3 is connected to the input end of the gearbox 4. The same housing 5 is fixedly connected to the upper side of the two equipment boxes 2. Two rotating shafts 6 are symmetrically rotatably connected to the housing 5. The output ends of the two gearboxes 4 are respectively fixedly connected to the two rotating shafts 6. Multiple shredding blades 7 are fixedly connected to the shaft wall of the rotating shaft 6 inside the housing 5. A guide hopper 8 is fixedly connected between the two equipment boxes 2. The guide hopper 8 is located below the housing 5. An auxiliary mechanism is installed between the guide hopper 8 and the equipment box 2.

[0025] The auxiliary mechanism includes a rotating shaft 9 rotatably connected between two equipment boxes 2. Both the equipment box 2 and the guide hopper 8 have shaft holes 10. The rotating shaft 9 passes through the equipment box 2 and the guide hopper 8 through the shaft holes 10. A driven gear 11 is fixedly sleeved on the shaft wall of the rotating shaft 9. A fixing hole 12 is provided on the equipment box 2. The driven gear 11 passes through the equipment box 2 through the fixing hole 12. A driving gear 13 that meshes with the driven gear 11 is fixedly sleeved on one of the rotating shafts 6. Multiple sleeves 14 are fixedly sleeved on the shaft wall of the rotating shaft 9 located in the guide hopper 8. Multiple pulling claws 15 are evenly fixedly connected to the outer wall of the sleeves 14. A hook 16 is fixedly connected to the end of the pulling claw 15 away from the sleeve 14.

[0026] In the above embodiment, during use, two motors 3 are started, which drive two gearboxes 4 to operate. The two gearboxes 4 drive two rotating shafts 6 to rotate at high speed. The two rotating shafts 6 drive multiple shredding blades 7 to rotate at high speed. The material is placed into the housing 5, and the multiple high-speed rotating shredding blades 7 work together to shred the material. The rotating shaft 6 drives the drive gear 13 to rotate, which drives the driven gear 11 to rotate. The driven gear 11 drives the rotating shaft 9 to rotate, which drives multiple pulling claws 15 to rotate. The multiple pulling claws 15 can pull the material on the shredding blades 7, thereby enabling the shredded material to quickly detach from the shredding blades 7. The multiple hooks 16 can further shred the material, improving the shredding effect. The rotating multiple pulling claws 15 can also move the material blocked in the guide hopper 8, allowing the material to slide smoothly in the guide hopper 8. This allows the shredded material to smoothly detach from the shredder, effectively improving the smoothness of operation of the large dual-shaft shredder.

[0027] Two connecting plates 17 are symmetrically fixedly connected to the bottom of the guide hopper 8. The same vibration motor 18 is fixedly connected between the two connecting plates 17. The vibration motor 18 is tightly fitted to the bottom of the guide hopper 8. The vibration motor 18 can drive the guide hopper 8 to vibrate, thereby improving the smoothness of material discharge.

[0028] A feeding hopper 19 is fixedly connected to the upper side of the housing 5, and baffle plates 20 are symmetrically fixedly connected to the upper side of the feeding hopper 19, which can improve the convenience of feeding and prevent materials from falling out of the shredder.

[0029] Multiple feet 21 are fixedly connected to the bottom of both mounting bases 1. The multiple feet 21 are located at the four corners of the bottom of the equipment box 2, which can lift the bottom of the mounting base 1 off the ground and improve its adaptability to the placement environment.

[0030] The diameter of the driving gear 13 is larger than that of the driven gear 11, which can increase the relative rotational speed of the driven gear 11, thereby increasing the rotational speed of the pulling claw 15, thus improving the material feeding efficiency and the smoothness of material discharge.

[0031] The shredding blades 7 located on the two rotating shafts 6 are arranged in an alternating manner, which can improve the shredding effect.

[0032] A support tube 22 is fixedly connected between the gearbox 4 and the housing 5. The rotating shaft 6 is rotatably connected to the inner wall of the support tube 22 through a ball bearing, which can support the rotating shaft 6 and improve the stability of the rotating shaft 6.

[0033] A reinforcing crossbar 23 is fixedly connected between two adjacent foot posts 21, which can improve the structural strength of the foot posts 21, thereby improving the load-bearing capacity of the foot posts 21 and improving the stability of the mounting base 1.

[0034] Working Principle: During operation, two motors 3 are started, driving two gearboxes 4, which in turn drive two rotating shafts 6 to rotate at high speed. These shafts, in turn, drive multiple shredding blades 7 to rotate at high speed. Material is placed inside the housing 5, where the high-speed rotating blades 7 work together to shred the material. The rotating shafts 6 drive the drive gear 13 to rotate, which in turn drives the driven gear 11 to rotate. The driven gear 11 then drives the rotating shaft 9 to rotate, which in turn drives multiple pulling claws 15 to rotate. These claws pull the material on the shredding blades 7, allowing the shredded material to quickly detach from the blades. Multiple hooks 16 further shred the material, improving the shredding effect. The rotating pulling claws 15 also dislodge material clogged in the guide hopper 8, allowing it to slide smoothly within the hopper and detach smoothly from the shredder. This effectively improves the smoothness of operation of the large dual-shaft shredder.
