Description

Technical Field

[0001] This utility model relates to the technical field of beet shredder equipment maintenance, specifically to a beet shredder blade delivery mechanism. Background Technology

[0002] The beet shredder is one of the key pieces of equipment on the sugar factory production line. It is mainly used to cut beets into shreds of a certain size for further processing in the subsequent sugar juice extraction process. The blade is the core component of the shredder. The shredder has multiple blade holders, and multiple blades are arranged on the blade holders. The blades are corrugated blades with a milled structure.

[0003] Due to the hardness of beets and their tuberous structure, the blades of the shredder are prone to damage during use. The blades need to be inspected and replaced by the operator. When replacing the blades, the blade holder needs to be removed together. After removal, the blades are removed from the blade holder for replacement. After the blades have been replaced, the blade holder is reinstalled in its original position.

[0004] Due to its considerable weight, the blade holder requires frequent operation on both sides during disassembly. After removing the nut on one side, the clamp and blade on the other side of the blade holder detach directly, making them prone to falling and causing secondary damage. Furthermore, new blades need to be installed back into the blade slot after disassembly. Manually flipping the blade holder is not only inconvenient to operate, but also labor-intensive due to the large number of blade holders on the shredder, resulting in high maintenance costs. Utility Model Content:

[0005] To address the shortcomings of existing technologies, this utility model provides a blade-dispensing mechanism for a beet shredder. This mechanism can fix and automatically rotate the blade holder, replacing the manual rotation step. It effectively limits the clamps and blades on the blade holder, reduces labor intensity, and helps improve maintenance efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Detailed implementation method:

[0024] like Figure 1-3 As shown, a beet shredder's blade delivery mechanism is primarily used for the maintenance and replacement of the blade holder 5 and the blade 5.3, assisting operators in the replacement operation. This mechanism is supported by a support 1, with a groove plate 12 for holding bolts fixed to the inner side of the support 1 at an angle. After the blade holder 5 is fixed to the fixing assembly 4, the bolts fall into the groove plate 12 after the nut 5.1 is removed. Slide rails 2 are vertically fixed at both ends of the support 1; a sliding groove 3 is slidably provided on the slide rail 2; a fixing assembly 4 is rotatably mounted on the top of the sliding groove 3; a lifting cylinder 11 is fixed to the support 1; the telescopic end of the lifting cylinder 11 is fixed to one side of the sliding groove 3, providing the fixing assembly 4 with a lifting function and ensuring sufficient space for the fixing assembly 4 to rotate.

[0025] like Figure 1-4As shown, the fixing component 4 includes: a side plate 4.1, a drive motor 4.2, a positioning rod 4.3, a support frame 4.4, and a pressure frame screw 4.5; the drive motor 4.2 is fixed to the top outer side of the slide groove 3; the drive end of the drive motor 4.2 is connected to the side plate 4.1 via a shaft; the side plates 4.1 are fixedly connected to each other via the positioning rod 4.3; the positioning rod 4.3 fits into the arc-shaped groove 5.4 of the tool holder 5; an L-shaped slot 4 is provided on the edge of the side plate 4.1 opposite to the positioning rod 4.3. .6; The two ends of the support frame 4.4 are provided with joints 4.7 that mate with the L-shaped slots 4.6; The support frame 4.4 and the positioning rod 4.3 clamp and fix the tool holder 5; A through hole 4.8 is provided at one end of the side plate 4.1, and the through hole 4.8 passes through the plate and enters the L-shaped slot 4.6; A pressure screw 4.5 is rotatably provided in the through hole 4.8, and the pressure screw 4.5 enters the L-shaped slot 4.6 to restrict the movement of the joints 4.7 of the support frame 4.4.

[0026] like Figure 1-4 As shown, the following optimizations will be made:

[0027] The fixed assembly 4 is equipped with a first positioning rod 4.31 and a second positioning rod 4.32. The second positioning rod 4.32 is threadedly fixed to the side plate 4.1 via a connector. The outer side of the side plate 4.1 is equipped with a limiting wheel 4.9 to restrict the flipping angle. The limiting wheel 4.9 prevents the fixed assembly 4 from flipping beyond the maximum limit. After reaching the maximum angle, the limiting wheel 4.9 contacts one side of the slide groove 3. The support frame 4.4 includes one or more stop bars 4.41. The stop bars 4.41 are fixedly connected by a connecting rod 4.42. The number of stop bars 4.41 on the support frame 4.4 is consistent with the number of rows of blades 5.3 on the blade holder 5. The blade holder currently has three rows of blades, and there are three stop bars. Each stop bar 4.41 has a connector 4.7 at both ends that mates with an L-shaped slot 4.6. The side plate 4.1 has L-shaped slots 4.6 corresponding to the number of each connector 4.7. The blade holder is an existing shredder component and will not be described in detail.

[0028] Furthermore, to facilitate the installation of the tool holder 5, a movable platform 6 is provided on the back of the support 1; a roller conveyor 8 is provided on the movable platform 6; a tool holder 5 to be replaced is placed on the roller conveyor 8; a base 7 is provided below the movable platform 6, and a traveling wheel 9 is provided at the bottom of the base 7; a counterweight 10 is fixed on the inner side of the base 7; when the fixing component 4 is flipped to a horizontal state, it should be flush with the movable platform 6 after it is lowered.

[0029] Unless otherwise specified, the above methods of fastening are all achieved using welding or threaded fastening, which are common techniques employed by industry professionals.

[0030] The working principle is as follows:

[0031] When the tool holder 5 needs to be installed, flip the fixing component 4 to a horizontal position. The support frame 4.4 is now located above the fixing component 4. Turn the knob of the pressure frame screw 4.5 to loosen the pressure frame screw 4.5. Then, take out the connector 4.7 of the support frame 4.4 from the L-shaped slot 4.6 and put the tool holder 5 on the support platform into place. The arc-shaped slot 5.4 of the tool holder 5 fits into the positioning rod 4.3. After putting in the tool holder 5, put the support frame 4.4 back into its original position and tighten the pressure frame screw 4.5. Control the drive motor 4.2 to flip the fixing component 4 to facilitate the removal of the blade 5.3 of the tool holder 5. Remove the nut 5.1 and the bolt falls into the slot plate 12. At this time, the clamp 5.2 that fixes the blade 5.3 on the tool holder 5 is blocked by the support frame 4.4, which prevents the blade 5.3 from falling directly and avoids secondary damage to the blade 5.3. Remove the support frame 4.4 and then take out the blade 5.3. This method ensures precise control of the clamps and blades during disassembly, preventing all components on the other side from being released from their restraints when removing nut 5.1 on one side.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
