Description

Technical Field

[0001] The present application relates to the technical field of waste treatment, and more particularly to a modular crusher. Background Art

[0002] When a crusher processes materials, it generally uses the cooperation of the fixed blade and the movable blade to crush the materials by tearing and shearing. In the process of interaction with the materials, the fixed blade and the movable blade will be worn, and as the amount of material processed increases, the wear of the fixed blade and the movable blade will increase accordingly, which will affect the crusher's processing effect on the materials. Therefore, regular maintenance of the fixed blade and the movable blade is required.

[0003] In the prior art, a crusher generally has multiple fixed blades, each of which is independently fixed on the crushing table. If the fixed blades are bolted to the crushing table, the independent bolting method can quickly complete the replacement of old parts with new ones when the fixed blades are maintained, but it is necessary to increase the structural strength of the crushing table and the fixed blades and the connection strength between the two, which not only increases the weight of the entire crusher, but also increases the manufacturing cost of the crusher. If the fixed blades are welded to the crushing table, when the fixed blades are maintained, it is necessary to repair the fixed blades by welding, and use auxiliary tools to adjust the shape of the fixed blades to a reasonable size, which is time-consuming and labor-intensive. In addition, if you want to replace the fixed blades, you need to replace the entire combination of the fixed blades and the crushing table, which is costly, heavy, and inconvenient to replace.

[0004] Therefore, how to improve the convenience of crusher maintenance has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0043] The core of this application is to provide a modular crusher to improve the convenience of crusher maintenance.

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] A crusher is a device that reduces the size of materials. It generally consists of a crushing table, a rotor, and a drive. The crushing table serves as the mounting base for the other components, which are bolted to the crushing table. The inner surface of the crushing table forms a crushing chamber, which contains fixed and rotating blades. When processing materials, the crusher generally uses the interaction of fixed and rotating blades to break the materials by tearing and shearing. During this interaction with the material, the fixed and rotating blades will wear. As the material processing volume increases, the wear of the fixed and rotating blades increases accordingly, which affects the crusher's processing efficiency. Therefore, regular maintenance of the fixed and rotating blades is required.

[0046] Traditional crushers generally have multiple fixed blades, each of which is independently fixed to the crushing table. If the fixed blades are bolted to the crushing table, the independent bolting method can quickly complete the replacement of old parts with new ones during maintenance, but it is necessary to increase the structural strength of the crushing table and the fixed blades and the connection strength between the two, which not only increases the weight of the entire crusher, but also increases the manufacturing cost of the crusher. If the fixed blades are welded to the crushing table, when maintaining the fixed blades, it is necessary to repair the fixed blades by welding, and use auxiliary tools to adjust the shape of the fixed blades to a reasonable size, which is time-consuming and labor-intensive. In addition, if you want to replace the fixed blades, you need to replace the entire combination of the fixed blades and the crushing table, which is costly, heavy, and inconvenient to replace.

[0047] For this reason, Figure 1As shown, the embodiment of the present application discloses a modular crusher, including a support module 100, a fixed cutting module 200, a rotary cutting module 300, and a drive module 400. By adopting a modular design for the easily-worn parts of the crusher, a plurality of fixed blades 202 are arranged on a fixed frame 201, and the fixed frame 201 is detachably connected to the support module 100, thereby realizing the connection between the fixed cutting module 200 and the support module 100. When the fixed blades 202 are to be maintained, it is only necessary to replace the fixed cutting module 200 as a whole to replace all the fixed blades 202, without the need to disassemble and assemble the new fixed blades 202 one by one, thereby improving the convenience of replacing the fixed blades 202. Moreover, under the premise of ensuring the overall strength of the module, the fixed cutting module 200 has a more streamlined structure than a plurality of independent fixed blade cutting modules, thereby achieving the lightweight requirement of the crusher, thereby improving the convenience of crusher maintenance, and reducing the manufacturing cost of the crusher.

[0048] The following will be combined Figures 1 to 6 The modular crusher disclosed in the embodiment of the present application is specifically explained and illustrated.

[0049] Among them, Figures 2 to 4 As shown, the support module 100 includes a pair of cross beams 101 and longitudinal beams 102, and the cross beams 101 and longitudinal beams 102 are arranged to form a blanking area 103, so that the material falls into the blanking area 103 after being cut and slides along the lower chute to the designated position.

[0050] In some embodiments, as Figure 2 and Figure 3 As shown, the crossbeam 101 and the longitudinal beam 102 can be made of I-shaped steel and connected by welding to enclose a blanking area 103. At the same time, a chute fixing interface 105 is provided on the longitudinal beam 102, so that the lower chute can be easily fixed to the bottom of the blanking area 103 by fasteners such as bolts, so that the material falls into the blanking area 103 after being cut and slides along the lower chute to the designated position. In order to improve the bearing capacity of the support module 100, a plurality of reinforcing ribs can be arranged at intervals along the length direction of the crossbeam 101 and the longitudinal beam 102, thereby improving the compressive resistance of the crossbeam 101 and the longitudinal beam 102, and further improving the overall bearing capacity of the support module 100. Specifically, the reinforcing ribs can be arranged between the upper and lower flanges of the I-shaped steel and evenly spaced along the length direction of the crossbeam 101 and the longitudinal beam 102, so as to ensure that the crossbeam 101 and the longitudinal beam 102 are evenly stressed.

[0051] like Figure 5As shown, the fixed cutting module 200 includes a fixed frame 201 and a plurality of fixed blades 202 spaced apart on the fixed frame 201, and the fixed frame 201 is detachably connected to the support module 100. When the fixed blades 202 are to be maintained, all the fixed blades 202 can be replaced by simply replacing the fixed cutting module 200 as a whole, without having to disassemble and assemble the new fixed blades 202 one by one. This improves the convenience of replacing the fixed blades 202. While ensuring the overall strength of the module, the fixed cutting module 200 has a more streamlined structure than multiple independent fixed blade cutting modules, thereby achieving the lightweight requirements of the crusher, thereby improving the convenience of crusher maintenance and reducing the manufacturing cost of the crusher.

[0052] In some embodiments, as Figure 4 As shown, a first positioning pin hole 1021 and a first fixing hole 1022 are provided on the longitudinal beam 102 of the support module 100. Figure 5 As shown, a second positioning pin hole 2012 and a second fixing hole 2013 are provided on the fixing frame 201. When the fixed cutting module 200 and the support module 100 are assembled, the second positioning pin hole 2012 can be matched with the first positioning pin hole 1021 to locate the installation position of the fixed cutting module 200, and then the second fixing hole 2013 can be matched with the first fixing hole 1022 to achieve the fixation of the fixed cutting module 200. Specifically, two first positioning pin holes 1021 can be used, and the two first positioning pin holes 1021 are located at diagonal positions of the support module 100. At the same time, the second positioning pin hole 2012 is provided on the fixing frame 201 at a position corresponding to the first positioning pin hole 1021, so that the installation and positioning of the fixed cutting module 200 can be achieved by matching the two sets of positioning pin holes with the positioning pins. The first fixing holes 1022 can be threaded holes, and multiple first fixing holes 1022 can be spaced apart along the circumference of the support module 100. Meanwhile, the second fixing holes 2013 can be plain holes that mate with the first fixing holes 1022, thereby allowing the cutting module 200 to be connected and fixed to the support module 100 via fasteners such as bolts. Of course, the first fixing holes 1022 can also be plain holes, while the second fixing holes 2013 can be threaded holes that mate with the first fixing holes 1022, thereby allowing the cutting module 200 to be connected and fixed to the support module 100 via fasteners such as bolts. It should be noted that the number of first locating pin holes 1021 can also be three, four, or more, and the second locating pin holes 2012 can mate with the first locating pin holes 1021. In addition, the number of the first fixing holes 1022 may be three, four, five or more, and the second fixing holes 2013 are adapted to the first fixing holes 1022 . The number of the first positioning pin holes 1021 and the first fixing holes 1022 is not limited herein.

[0053] like Figure 1 As shown, the rotary cutting module 300 is disposed on the supporting module 100. Figure 6 As shown, the rotary cutting module 300 includes a rotating shaft 301 and multiple movable blades 302 spaced apart on the rotating shaft 301. A drive module 400 is connected to the rotating shaft 301 to provide power to the rotary cutting module 300. Furthermore, the movable blades 302 are spaced apart from the fixed blades 202 so that when the drive module 400 drives the rotating shaft 301 to rotate, the movable blades 302 and the fixed blades 202 engage with each other, thereby cutting the material.

[0054] In some embodiments, as Figure 1 As shown, the rotating shaft 301 can be a single shaft crusher, and the rotating shaft 301 is arranged parallel to the longitudinal beam 102. The rotating shaft 301 includes a driving end 3011 and a supporting end 3012. The driving module 400 is connected to the driving end 3011 of the rotating shaft 301 to drive the rotating shaft 301 to rotate. At the same time, a fixed seat 1011 for supporting the rotating shaft 301 is provided on the beam 101, and the driving end 3011 and the supporting end 3012 of the rotating shaft 301 are both provided with a bearing seat 303, and the rotating shaft 301 rotates in cooperation with the bearing seat 303, and the rotating shaft 301 is installed on the fixed seat 1011 through the bearing seat 303, and a mounting groove for installing the bearing seat 303 is provided on the fixed seat 1011, so that the bearing seat 303 can be installed in the mounting groove of the fixed seat 1011, and at the same time, an arc-shaped avoidance groove 2014 for avoiding the rotating shaft 301 is provided on the fixed frame 201, so that when the bearing seat 303 of the rotating shaft 301 is installed in the mounting groove of the fixed seat 1011, the movable knife 302 can extend into the fixed frame 201 and cooperate with the fixed knife 202. For ease of understanding, the fixing seats 1011 on the two crossbeams 101 are defined as the support end fixing seat and the drive end fixing seat, respectively. The bearing seat 303 of the drive end 3011 of the rotating shaft 301 is defined as the drive side bearing seat, and the bearing seat 303 of the support end 3012 of the rotating shaft 301 is defined as the support side bearing seat. During installation, the support side bearing seat of the rotating shaft 301 is fixed to the support end fixing seat using fasteners such as bolts, and the drive side bearing seat of the rotating shaft 301 is fixed to the drive end fixing seat using fasteners such as bolts. At the same time, a drive installation interface 104 for installing the drive module 400 is provided at the end of the longitudinal beam 102 on the side close to the drive end 3011 of the rotating shaft 301. The drive module 400 is detachably connected to the drive installation interface 104 via a connector.

[0055] Of course, the number of rotating shafts 301 can be but not limited to one in the above embodiment, and two, three or more can also be used, and each rotating shaft 301 is arranged parallel to the longitudinal beam 102, so that the movable knife 302 and the fixed knife 202 on each rotating shaft 301 engage with each other, thereby realizing cutting of the material, that is, the modular design of the present application is not limited to single-shaft crushers, and can also be applied to multi-shaft crushers such as two-shaft and three-shaft crushers.

[0056] In the above embodiment, the fixing base 1011 is also provided with a lubrication assembly interface to facilitate connection with the lubrication assembly, thereby ensuring the stability of the rotation of the rotating shaft 301. And / or, the fixing base 1011 may also be provided with a logo installation interface for installing a nameplate, warning sign, etc.

[0057] In some embodiments, as Figures 1 to 4 As shown, the drive module 400 includes a hydraulic motor 401 and a shock absorber arm flange 402. The drive mounting interface 104 includes a drive fixing interface 1041 and a safety pin fixing interface 1042. During installation, the hydraulic motor 401 is connected to the connector via the shock absorber arm flange 402, and the connector is then connected to the corresponding drive fixing interface 1041. Bolts or other fasteners can be used to connect the shock absorber arm flange 402, the connector, and the drive fixing interface 1041. When the drive module 400 needs to be replaced, only the shock absorber arm flange 402 needs to be adjusted, without having to adjust other functional modules.

[0058] like Figure 1 As shown, the modular crusher also includes a crushing chamber module 500, which is arranged on the fixed frame 201 that fixes the cutting module 200 to form a closed material processing space 501, thereby ensuring that the crusher can effectively and safely process materials.

[0059] like Figures 2 to 4As shown, in some embodiments, the support module 100 is provided with lifting lugs 106 for easy movement. These lifting lugs 106 can be installed on the reinforcing ribs of the longitudinal beams 102. There can be four lifting lugs 106, symmetrically distributed on the two longitudinal beams 102, to facilitate the movement and assembly and disassembly of the support module 100 using lifting equipment. Furthermore, / or, the support module 100 can also be provided with leg interfaces 107 to facilitate the connection of legs to raise the overall height of the crusher to accommodate different operating conditions. Furthermore, / or, the support module 100 can also be provided with a displacement system interface 108 to facilitate connection to mobile equipment, thereby facilitating the adjustment of the crusher's position.

[0060] It can be seen from the above embodiments that the modular crusher provided in this application modularizes the various functional parts of the crusher and forms the overall structure of the crusher through detachable connections. It can not only realize the independent and rapid replacement of a single module, but also ensure the simplicity of design and ease of use, thereby improving the crusher's ability to cope with complex materials.
