Description

Technical Field

[0001] This utility model relates to the field of toothed roller crusher technology, and in particular to a fastening structure for the anti-impact partition of a toothed roller crusher cover. Background Technology

[0002] Toothed roll crushers are equipment suitable for crushing raw materials in industries such as coal, metallurgy, mining, chemicals, and building materials. The impact baffle of a toothed roll crusher is a component designed inside the crusher, primarily used to reduce the impact force of materials during the crushing process, protecting the machine and extending its service life. Specifically, the impact baffle is usually installed inside the crushing chamber of the crusher.

[0003] The existing shock-absorbing baffles inside the engine hood are fastened to the inner wall of the hood with multiple sets of bolts. The disadvantage of this installation method is:

[0004] 1. Because the impact baffle is located between the toothed roller and the inner wall of the machine cover, the bolts are installed before the toothed roller is installed. It is difficult to remove the bolts after the toothed roller is installed, which affects the replacement and maintenance of the impact baffle in the later stage.

[0005] 2. The bolts are tightened by a single nut on the outside. Under the high-frequency vibration of the crusher, the tightening force of the nut will be reduced, which will not only affect the use of the impact baffle, but also increase the maintenance work.

[0006] 3. The number of bolts required is large, resulting in a significant workload for installation.

[0007] To address the aforementioned issues, a fastening structure for the impact-resistant partition of a toothed roller crusher guard is proposed. Utility Model Content

A fastening mechanism is provided in the screw mounting holes, and an impact baffle plate is installed on the inner side of the fastening mechanism.

[0011] The fastening mechanism includes a fastening screw that is slidably installed through both the protective cover body and the impact baffle. A fastening bracket is threadedly connected to one end of the fastening screw, and a locking nut that is threadedly connected to the fastening screw is provided on the outside of the fastening bracket.

[0012] Furthermore, the screw mounting holes are set to 5, and the impact baffle is also provided with 5 reserved holes that are aligned and connected with the screw mounting holes.

[0013] Furthermore, the diameter of one end of the fastening screw is larger than the diameter of the other end, the inner end of the fastening screw is engaged with the recessed platform in the reserved hole, and the outer wall of the fastening screw is flush with the outer wall of the impact baffle.

[0014] Furthermore, the top of the protective cover body is fixed with a feed hopper by bolts, and the bottom is formed with a discharge trough. The impact baffle can slide in and out along the feed hopper and the discharge trough.

[0015] Furthermore, the protective cover body is also provided with movable mounting holes and fixed mounting holes located on both sides of the screw mounting hole.

[0016] Furthermore, the outer sides of the impact baffle are located between the movable mounting hole and the fixed mounting hole.

[0029] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] like Figures 1-4 As shown in the figure, the embodiment of the present invention provides a fastening structure for the anti-impact partition of a toothed roller crusher guard, including a guard body 1. The inner wall of the guard body 1 is provided with symmetrical and through screw mounting holes 103. A fastening mechanism 2 is provided in the screw mounting holes 103. An impact partition 3 is installed on the inner side of the fastening mechanism 2. The fastening mechanism 2 includes a fastening screw 202 that is slidably installed through the guard body 1 and the impact partition 3. A fastening bracket 201 is threadedly connected to one end of the fastening screw 202. A locking nut 203 that is threadedly connected to the fastening screw 202 is provided on the outer side of the fastening bracket 201.

[0031] In the above structure, the five threaded holes on the fastening bracket 201 also serve as the first layer of the nut structure in the double nut anti-loosening structure. During the installation of the double nuts, the bottom nut needs to be fixed before the top nut can be tightened. This method greatly increases the workload of installation. The fastening bracket 201 in this structure serves to lock the bottom nut as a whole, thereby reducing the workload of installation, and at the same time, it also serves to prevent loosening.

[0032] Five screw mounting holes 103 are provided, and five reserved holes 301 are also provided on the impact baffle 3, which are aligned and connected with the screw mounting holes 103. The five holes are evenly distributed on the fastening position of the impact baffle 3, which not only provides a stable fastening installation, but also reduces the number of screws used.

[0033] The diameter of one end of the fastening screw 202 is larger than that of the other end. The inner end of the fastening screw 202 is stuck in the recessed platform in the reserved hole 301. The outer wall of the fastening screw 202 is flush with the outer wall of the impact partition 3. When the crushing toothed roller is installed, it is located on the outer side of the impact partition 3. Therefore, the inner end of the fastening screw 202 cannot exceed the impact partition 3 to avoid friction damage to the toothed roller.

[0034] The top of the protective cover body 1 is fixed with a feed hopper by bolts, and the bottom is formed with a discharge groove. The impact baffle 3 can slide in and out along the feed hopper and the discharge groove. With this configuration, the impact baffle 3 can be removed from the top or bottom of the feed hopper after the fastening mechanism 2 is disassembled by removing the fastening screw 202.

[0035] The protective cover body 1 is also provided with movable mounting holes 101 and fixed mounting holes 102 located on both sides of the screw mounting hole 103.

[0036] The outer sides of the impact baffle 3 are located between the movable mounting hole 101 and the fixed mounting hole 102. This arrangement can prevent the impact baffle 3 from interfering with the installation of the moving toothed roller and the fixed toothed roller drive shaft.

[0037] A pad 201a is movably placed at the bottom of the fastening bracket 201. The pad 201a acts as a spring pad and provides initial shock absorption.

[0038] The working principle of this device is as follows: During installation, after the impact baffle 3 enters from the feed hopper at the top of the protective cover body 1, the reserved hole 301 is aligned with the screw mounting hole 103. Five sets of fastening screws 202 are inserted from the inside and pass through the impact baffle 3 and the protective cover body 1. The fastening frame 201 is simultaneously aligned with the outer end of the fastening screw 202. Using a tool, the fastening screw 202 is screwed into the threaded holes at the four outer ends and the center of the fastening frame 201. Finally, the locking nut 203 is screwed to the outermost end of the fastening screw 202 to complete the installation. Then, the moving toothed roller and the fixed toothed roller are installed in the movable mounting hole 101 and the fixed mounting hole 102, respectively.

[0039] During disassembly, the screw mounting holes 103 on the upper and lower sides are located in the external visible range of the moving toothed roller and the fixed toothed roller, so the fastening screw 202 can be directly removed. The screw mounting hole 103 in the middle part can adjust the moving toothed roller along the movable mounting hole 101 to the other side so that it can be exposed and then disassembled. In this way, the impact partition 3 can be quickly removed.

[0040] In addition, by adopting the above structure, the fastening bracket 201 acts as the bottom nut in the double nut anti-loosening structure. Together with the external locking nut 203, it effectively prevents loosening and reduces the interference of machine cover shaking on the fastening structure.

[0041] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0042] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
