[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0021] Example 1

[0022] The crushing device of the waste recycling equipment in highway construction described in this embodiment is as follows: Figure 1 As shown, it comprises a horizontally arranged roller 1, and connecting rods 4 for connecting with a driving device are arranged at the left and right ends of the roller 1, so as to facilitate the roller 1 to rotate through the driving device, thereby driving the crushing assembly to rotate;

[0023] The roller 1 is provided with a crushing assembly for crushing waste, which is convenient for crushing larger solid waste to make it smaller, which is convenient for collection and separation of materials such as steel bars wrapped in the waste;

[0024] The crushing assembly includes a plurality of vertically arranged limit rings 2 and cutter discs 3, which are cross-fitted on the roller 1 from left to right, and the two outermost ends are both limit rings 2, which is convenient for replacing and maintaining the cutter disc 3 separately, and also convenient for higher stability during the crushing process, avoiding falling off or displacement during the crushing process, which affects the crushing effect and work efficiency;

[0025] A connecting assembly is provided between the stop ring 2 and the cutter disc 3, and the connecting assembly is used to make the stop ring 2 and the cutter disc 3 form a whole, so as to improve their strength, thereby reducing wear and tear, increasing their service life, and thus reducing the cost of use;

[0026] The roller 1 is provided with a locking assembly for preventing the limit ring 2 and the cutter disc 3 from being displaced, so as to further improve the overall stability and prevent the limit ring 2 or the cutter disc 3 from falling off the roller 1 due to excessive strength of the waste during the crushing process;

[0027] The roller is a prior art, which refers to a cylindrical object that can rotate in a machine. The roller should have sufficient rigidity to ensure that the bending deformation does not exceed the allowable value under heavy load;

[0028] The driving device is only used to describe the connection usage scenario of the roller 1 for ease of understanding.

[0029] like Figure 2 As shown, the cutter disc 3 includes a fixing ring 3.1, the arc surface of which is provided with a plurality of slots distributed in a circle, each slot being provided with a blade 3.2 which is interference fit therewith, so that a single replacement and maintenance of the blade 3.2 is convenient when it is damaged, thereby reducing the use cost.

[0030] The blade tip of the blade 3.2 is a trapezoidal structure that is narrow at the top and wide at the bottom, and the contact surface with the waste material is provided with side edges, so as to prevent the blade tip of the blade 3.2 from being too sharp and being easily worn and broken during the crushing process, thereby improving the overall strength of the blade 3.2 and making it easier to crush the waste material, thereby improving the crushing efficiency and reducing the use cost;

[0031] The contact end of the blade 3.2 with the waste material may also be in a prism-shaped structure, which is convenient for ensuring that the contact surface with the waste material is small and does not affect the crushing effect, and is also convenient for avoiding the contact point with the waste material being too sharp and thin to cause breakage.

[0032] Example 2

[0033] This embodiment further illustrates the technology. Figure 3 and Figure 4 As shown, the connecting component is a limit rod 6, and the left and right side walls of the fixing ring 3.1 are provided with through holes connected to the slots, the limit rod 6 is independently installed in the through holes, and the two ends of the limit rod 6 are located outside the fixing ring 3.1, and the side walls of the limit ring 2 close to the cutter disc 3 are provided with grooves for inserting the limit rod 6, and the limit rod 6 and the groove are interference fit, and the length of the limit rod 6 located outside the fixing ring 3.1 is equal to the depth of the groove, so that the limit ring 2 and one side of the cutter disc 3 are conveniently mounted on the roller 1 and combined and connected through the limit rod 6 to form a whole, thereby improving its stability and strength, reducing its wear to a certain extent, and reducing the cost of use;

[0034] The limit rod 6 can be made of rubber material, and a number of steel wires are embedded inside it to increase the strength, so as to limit the blade 3.2 and prevent it from falling off during the crushing process. When in use, when the blade 3.2 moves outward, it will drive the limit rod 6 to move and bend and limit it, and the wear of the limit rod 6 and the fixing ring 3.1 is relatively low. When the blade 3.2 stops moving outward, the characteristics of the limit rod 6 itself can accelerate the resetting of the blade 3.2 during the crushing process.

[0035] The cross section of the roller 1 is in a "cross" shape, and the inner ring shapes of the limiting ring 2 and the fixing ring 3.1 are consistent with it. The limiting ring 2 and the cutter disc 3 are both in clearance fit with the roller 1, which is convenient for fitting the limiting ring 2 and the cutter disc 3 on the roller 1, and when the roller 1 rotates, the limiting ring 2 and the cutter disc 3 will not rotate with it, so that the stability is higher;

[0036] The outer side wall of the roller 1 has rounded corners to prevent the limiting ring 2 and the cutter disc 3 from colliding and rubbing with the roller 1, thereby increasing the overall strength and making it less prone to wear.

[0037] The limiting ring 2 and the fixing ring 3.1 are both special-shaped rings, and the inner rings thereof are not circular structures. The limiting ring 2 and the fixing ring 3.1 can also be understood as a disc structure, and a channel having the same cross section as the roller 1 is opened at the center of the disc, and there is a clearance fit between the channel and the roller 1;

[0038] The clearance fit between the stop ring 2, the cutter disc 3 and the roller 1 is a minimum clearance fit. The clearance fit is an existing fit relationship, which refers to a fit with a gap (including a minimum gap equal to zero), that is, the actual size of the hole is always greater than or equal to the actual size of the shaft. It is often used in the field of mechanical manufacturing to ensure the connection between parts and the smooth movement. By controlling the gap between parts, excessive friction and wear during the movement process can be avoided;

[0039] The limiting ring 2, the cutter disc 3 and the roller 1 may also be fitted with an interference fit;

[0040] The roller 1 and the cross section can also be in a "triangular" structure, or a rectangular structure cannot be a circular structure, and the edges and corners thereof are all rounded.

[0041] Example 3

[0042] This embodiment further illustrates the technology. Figure 1 As shown, the locking assembly is a limit nut 5, and the side walls at both ends of the roller 1 are provided with external threads that are threadedly matched with the limit nut 5, and the external threads are located on the roller 1 outside the area of ​​the limit ring 2 and the cutter disc 3, which is convenient for fixing the position of the limit ring 2 and the cutter disc 3 to avoid displacement when the roller 1 is driven to rotate and when the crushing work is performed;

[0043] In actual use, a second threaded through hole that is connected to the left and right can be opened on the limit nut 5, and a third threaded countersunk hole that is connected to the second through hole can be opened on the side wall of the limit ring 2 at the outer end. The second threaded through hole and the third threaded countersunk hole are equipped with screws that are threadedly matched with them, so as to avoid the limit nut 5 from loosening during the crushing process, thereby causing the limit ring 2 and the cutter disc 3 to loosen and affect the crushing effect or even be damaged; the locking assembly can also include two nuts, and the thread directions of the two nuts are opposite, so as to increase the limiting effect of the limit ring 2 and the cutter disc 3, thereby reducing the probability of the limit ring 2 and the cutter disc 3 falling off during the crushing process.

[0044] Example 7

[0045] This embodiment further illustrates the technology. The contact surfaces of the limit ring 2 and the fixed ring 3.1 are both provided with sealing rings, which are not shown in the figure, to block the debris and dust generated during the crushing process and prevent them from entering the gap between the limit ring 2 and the cutter disc 3 and the roller 1 to affect their installation and disassembly.

[0046] The sealing ring can be installed and fixed on the side wall of the limiting ring 2, which is convenient for reducing the influence of the sealing ring on the heat dissipation performance of the blade, causing heat to accumulate on the blade, thereby affecting the life and stability of the blade. Working principle: first, the limiting ring 2 and the cutter disc 3 are sequentially mounted on the roller 1. During the mounting process, the limiting ring 2 and the cutter disc 3 are connected by the limiting rod 6, and the outermost side is the limiting ring 2. Then, the limiting ring 2 and the cutter disc 3 are fixed on the roller 1 by the limiting nut 5. Finally, the two crushing components are arranged in parallel and connected to the driving device through the connecting rod 4.
