Description

Technical Field

[0001] This utility model relates to the field of resource recycling technology, specifically a block dismantling machine. Background Technology

[0002] In modern industrial recycling and resource recovery systems, plastic and metal waste are compressed and packaged into high-density bales to reduce transportation costs and improve storage efficiency. However, before these neatly arranged bales can enter the reprocessing stage, they need to be broken down and crushed using bale dismantling machines to restore them to loose materials or granular forms suitable for subsequent processing, thereby achieving efficient recycling of resources.

[0003] Existing bale breakers mostly employ a dual-shaft meshing design, with two shafts arranged horizontally side-by-side. The material is crushed by the shearing force generated by the opposing rotation of the two shafts. However, this dual-shaft horizontal layout requires a large amount of lateral space, resulting in an excessively large footprint and hindering usability. Therefore, we propose a bale breaker that effectively addresses these drawbacks. Utility Model Content

[0004] The purpose of this utility model is to provide a block dismantling machine to solve the problem mentioned in the background art that the existing block dismantling machine adopts a dual-shaft meshing type and occupies too much space.

[0025] 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.

[0026] Please see Figures 1 to 5 A block dismantling machine includes a frame 1 that provides support for other components in the equipment. A control box is fixed on the frame 1 for controlling the entire machine.

[0027] This embodiment also includes: a block conveying mechanism 2, a discharge mechanism 3, and a crushing mechanism 4, which are used to solve the problem that the existing block dismantling machine adopts a dual-shaft meshing type and occupies too much space.

[0028] The following is a description of the block conveying mechanism 2:

[0029] The bale conveying mechanism 2 is mounted on the frame 1 and distributed along the length of the frame 1, and is used to convey bales. In this embodiment, the bale conveying mechanism 2 includes a conveyor belt 201 mounted on the frame 1, and a first motor 202 mounted on the frame 1 to drive the conveyor belt 201 to rotate cyclically. The first motor 202 is communicatively connected to the control box. By starting the first motor 202 through the control box, the conveyor belt 201 is driven to rotate cyclically. Then, the bales are placed on the conveyor belt 201, and the bales are conveyed to the crushing mechanism 4 for crushing.

[0030] The following is a description of the discharge mechanism 3:

[0031] The discharge mechanism 3 is mounted on the frame 1 and located at the unloading end of the bale conveying mechanism 2, discharging the crushed material. Specifically, the discharge mechanism 3 includes a discharge hopper 301 fixed to the frame 1 and located at the unloading end of the bale conveying mechanism 2. The discharge hopper 301 is inclined, allowing the material to slide down quickly by gravity. A discharge shaft 302 is rotatably connected to the frame 1 and located above the discharge hopper 301. Several material-pushing blades 303 are evenly distributed on the discharge shaft 302. When the discharge shaft 302 rotates, the material-pushing blades 303 rotate synchronously, and the mechanical thrust generated by the rotation actively pushes the material accumulated on the inclined surface of the discharge hopper 301 out. This design effectively avoids clogging problems caused by factors such as moisture and stickiness of the material, ensuring a continuous and efficient discharge process. Even when handling high-humidity or easily agglomerated materials, it can still maintain stable unloading efficiency.

[0032] In this embodiment, a first chain 5 is connected between the discharge shaft 302 and the bottommost crushing shaft 401. When the crushing shaft 401 rotates, it drives the discharge shaft 302 to rotate synchronously. This design cleverly utilizes the power source of the crushing mechanism 4, eliminating the need for an additional independent drive device. This not only simplifies the overall transmission system and reduces energy consumption, but also ensures that the discharge rhythm is highly matched with the crushing process, effectively avoiding material accumulation or discharge delay, and improving the continuity and automation level of equipment operation.

[0033] The following is a description of crushing mechanism 4:

[0034] The crushing mechanism 4 is mounted on the frame 1 and located above the discharge mechanism 3, and is used to crush the conveyed bales.

[0035] The crushing mechanism 4 includes several crushing shafts 401 rotatably connected to the frame 1 at equal intervals from top to bottom. A drive assembly 402 is mounted on the frame 1 to drive the crushing shafts 401 to rotate synchronously. Several crushing components 403 are fixed at equal intervals along the axial direction on each crushing shaft 401. When the drive assembly 402 drives the crushing shafts 401 to rotate synchronously, the crushing components 403 can crush the blocks. Since the crushing shafts 401 are arranged in an orderly manner along the vertical direction, a three-dimensional crushing plane is constructed that intersects perpendicularly with the conveyor belt 201, which can greatly save lateral space.

[0036] In this embodiment, there are three crushing shafts 401, and the adjacent crushing components 403 are staggered. This structural design can form multiple three-dimensional shearing surfaces in the vertical space when the crushing shafts 401 are in operation, which not only significantly expands the crushing coverage area, but also allows for multiple impacts and shearings on the block at multiple angles.

[0037] Additionally, the drive assembly 402 includes a second motor 4021 mounted on the frame 1, which is communicatively connected to the control box. A second chain 4022 is connected between the output end of the second motor 4021 and each crushing shaft 401. When the control box starts the second motor 4021, the second chain 4022 drives each crushing shaft 401 to rotate synchronously.

[0038] Using the above design, the control box is powered on, and the worker places the bale onto the conveyor belt 201. The control box then controls the first motor 202 to drive the conveyor belt 201, transporting the bale to the crushing position. Simultaneously, the second motor 4021 starts, driving the crushing shafts 401 and the discharge shaft 302 to rotate via a chain. When the conveyor belt 201 transports the bale to the crushing position, crushing can begin. After crushing, the material is driven down from the discharge hopper 301 by rotating feed vanes 303. If the crushing process gets stuck, a signal will automatically control the shafts to reverse via the control box, and then crushing will continue.

[0039] In some embodiments of this application, the crushing component 403 includes a cutter disc 4031 fixed to the crushing shaft 401, and a plurality of crushing blades 4032 are detachably connected to the cutter disc 4031 at equal intervals in the circumferential direction. When the crushing blades 4032 are damaged and cannot be used normally, the crushing blades 4032 can be replaced.

[0040] In traditional designs, the crusher blade 4032 is typically secured to the cutter head 4031 with screws. Replacing worn blades requires unscrewing all screws one by one, and installing new blades necessitates repeating this tedious tightening process. This severely limits the equipment's rapid maintenance and emergency response capabilities, making it difficult to meet the demands of continuous production. Therefore, the following design is proposed:

[0041] The cutter head 4031 has placement slots 6 that mate with each of the crushing blades 4032 for placing the blades. Two positioning pins 7 are fixed in each placement slot 6, and each crushing blade 4032 has positioning holes 8 that mate with the two positioning pins 7. When a crushing blade 4032 is placed in a placement slot 6, the positioning pins 7 and positioning holes 8 work together to position the blade and prevent movement. A sealing ring 9, which fits against the cutter head 4031, is bolted to the crushing shaft 401 to seal the placement slots 6. The sealing ring 9 has clearance holes 10 corresponding to each positioning pin 7, allowing the positioning pins 7 to be inserted into the clearance holes 10, thus preventing relative rotation between the sealing ring 9 and the cutter head 4031.

[0042] With the above design, when the crusher blades 4032 need to be replaced, first remove the bolts between the sealing ring 9 and the crushing shaft 401, then move the sealing ring 9 away from the cutter head 4031, and you can directly remove each crusher blade 4032 from the cutter head 4031. Then, place the new crusher blades 4032 one by one into the placement slot 6, and position them using the positioning pins 7 and positioning holes 8. Finally, fix the sealing ring 9 with bolts. The entire process eliminates the need for repetitive and tedious tightening procedures, greatly improving the equipment's rapid maintenance and emergency response capabilities.
