Description

Technical Field

[0001] The utility model relates to the technical field of shredders, in particular to a shredder with a convenient replacement of a cutter head. Background Art

[0002] A shredder is a mechanical device designed to crush various materials. It achieves this by shearing, tearing, and squeezing materials through high-speed rotating blades. As an important piece of machinery, shredders play a vital role in a variety of fields, including recycling, waste disposal, wood processing, and chemical raw materials. With rising environmental awareness and technological advancements, the application prospects of shredders are expanding.

[0003] In existing shredders, the cutter heads are usually fixed with bolts, and the entire shredding structure cannot be removed from the casing, making it inconvenient to replace the cutter heads. The cutter heads are prone to wear after long-term use, which will affect the working efficiency and shredding effect of the shredder. The worn cutter heads cannot effectively shred the materials, which may cause the shredded materials to be uneven in size and irregular in shape, not meeting production requirements, thereby reducing product quality. In addition, long-term downtime waiting for the cutter head replacement will cause delays in the entire production process and reduce output. Utility Model Content

The outer wall of the mounting rod 621 is equidistantly provided with mounting grooves, and a blade 623 is engaged with the interior of the mounting groove. A fixing hole 1 is provided inside the blade 623. A fixing hole 2 is equidistantly provided on the inner circumference of the fixing sleeve 622. The fixing hole 1 is communicated with the fixing hole 2. A locking rod 624 is engaged with the interior of the fixing hole 1 and the fixing hole 2. A threaded groove is provided at one end of the locking rod 624, and a nut 625 is threadedly connected to one end of the locking rod 624 through the threaded groove.

[0031] Furthermore, in the embodiment, the nut 625 is twisted to remove the nut 625 from one end of the engaging rod 624, the engaging rod 624 is taken out from the fixed sleeve 622 and the blade 623, and then the blade 623 is taken out from the fixed sleeve 622 for replacement, and the new blade 623 is engaged into the installation groove of the fixed sleeve 622, so that the fixing hole 1 is aligned with the fixing hole 2, the engaging rod 624 is inserted into the interior of the fixing hole 1 and the fixing hole 2, the nut 625 is put on one end of the engaging rod 624, and the nut 625 is rotated to fix the engaging rod 624.

[0032] Example 3

[0033] On the basis of embodiments 1 and 2, a preferred embodiment of a shredder that is easy to replace a cutter head provided by the present invention is as follows: Figure 1-4 As shown: the vibration assembly 8 includes: a dividing plate 811, which is movably arranged inside the shredder box 1; a rotating shaft 815, which is movably installed on one side of the outer wall of the shredder box 1; a second pulley 819, which is fixedly sleeved on the outer wall of one of the engaging outer cylinders 612; one end of the rotating shaft 815 is rotatably connected to the shredder box 1 through a bearing, and the outer wall fixed sleeve of the rotating shaft 815 is provided with a protrusion 816, and the other end of the rotating shaft 815 movably passes through the inner side of the fixed vertical plate 611 and extends to the other side of the fixed vertical plate 611, and the fixed sleeve is provided with a pulley 1 817, and the pulley 1 817 and the pulley 2 819 are connected by a belt 818 for transmission. The upper partition 812 is symmetrically installed on the top of the dividing plate 811, and the lower partition 814 is symmetrically installed on the bottom of the dividing plate 811. Connecting plates 813 are fixedly installed on both sides of the dividing plate 811, and the connecting plate 813 passes through the connecting port and is movably connected to the shredder box 1 through the connecting port.

[0034] Furthermore, in the embodiment, pulley 2 819 fixed to the outer wall of one of the engaging outer cylinders 612 also rotates accordingly. Pulley 2 819 is connected to pulley 1 817 through belt 818, thereby driving the rotating shaft 815 to rotate. The protrusion 816 fixed to the outer wall of the rotating shaft 815 rotates with the rotating shaft, continuously hitting the connecting plate 813, so that the connecting plate 813 drives the lower partition 814 to move up and down, generating a vibration effect. The upper partition 812 and the lower partition 814 prevent the material from scattering outward through the connecting port. This vibration helps to separate the material and prevent the material from being blocked.

[0035] When in use, first pour the material to be shredded into the interior of the shredder box 1 through the discharge hopper 4, and start the motor 613. After the motor 613 is started, its output end drives one of the engaging outer cylinders 612 to rotate. Since the outer wall of the engaging outer cylinder 612 is fixedly sleeved with a gear 614, and the gears 614 are meshed and connected, the two engaging outer cylinders 612 will rotate synchronously. The engaging outer cylinder 612 drives the engaging inner cylinder 617 and the cross engaging block 2 618 to rotate simultaneously through the mounting rod 621, and the mounting rod 621 drives the blade 623 to rotate through the fixed sleeve 622 to shred the material. When the motor 613 drives the engaging outer cylinder 612 to rotate, the outer cylinder 617 and the cross engaging block 2 618 are meshed and connected. When rotating, one of the pulleys 819 fixed on the outer wall of the outer cylinder 612 also rotates accordingly. The pulley 819 is connected to the pulley 1 817 through the belt 818, thereby driving the rotating shaft 815 to rotate. The protrusion 816 fixed on the outer wall of the rotating shaft 815 rotates with the rotating shaft, and continuously hits the connecting plate 813, so that the connecting plate 813 drives the lower partition 814 to move up and down, generating a vibration effect. The upper partition 812 and the lower partition 814 prevent the material from scattering outward through the connection port. This vibration helps to separate the material and prevent the material from being blocked. When the blade 623 needs to be replaced, first press the mounting rod 621 inward. The mounting rod 621 drives the engaging inner cylinder 617 to slide inwardly inside the fixed outer cylinder 616 through the slider 619. At the same time, the fixed outer cylinder 616 drives the guide rod 6111 to move outward and drives the spring 6112 to be compressed. The other end of the mounting rod 621 is disengaged from the engagement between the engaging outer cylinder 612 and the cross engaging block 1 615. One end of the mounting rod 621 is removed. After removing the other end, the pressure on the mounting rod 621 is released. The spring 6112 rebounds, driving the engaging inner cylinder 617 and the guide rod 6111 to slide inside the fixed outer cylinder 616 toward the shredder box 1. After returning to its original position, the other end of the mounting rod 621 is removed. The end is disengaged from the engaging inner cylinder 617 and the cross engaging block 2 618, and the mounting rod 621 is removed. Then, the nut 625 is twisted to remove the nut 625 from one end of the engaging rod 624, and the engaging rod 624 is taken out from the fixed sleeve 622 and the blade 623. Then, the blade 623 is taken out from the fixed sleeve 622 for replacement. The new blade 623 is engaged into the mounting groove of the fixed sleeve 622, and the fixing hole 1 is aligned with the fixing hole 2. The engaging rod 624 is inserted into the inside of the fixing hole 1 and the fixing hole 2, and the nut 625 is put on one end of the engaging rod 624. The nut 625 is turned to fix the engaging rod 624.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
