[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0022] Please refer to Figures 1-4, an embodiment provided by the present utility model: a crushing device for the production of recycled environmentally friendly permeable concrete, including a crushing device box 1, a first crushing roller 2 is installed inside the crushing device box 1, a driving wheel 3 is installed at one end of the first crushing roller 2, a connecting shaft 4 is installed at one end of the driving wheel 3, a second crushing roller 5 is installed on one side of the first crushing roller 2, a driven wheel 6 corresponding to the driving wheel 3 is installed at one end of the second crushing roller 5, auxiliary limiting seats 7 are installed on both sides of the inner wall of the crushing device box 1, a feeding box 10 is installed above the crushing device box 1, a cover plate 11 is installed above the feeding box 10, a retaining bar 17 is arranged at one end of the cover plate 11, a mounting seat 1002 is arranged at the upper end inside the feeding box 10, a fixing seat 13 is installed on one side of the mounting seat 1002, a support spring 15 is installed on one side of the fixing seat 13, and a support seat 16 is installed at one end of the support spring 15. It should be noted that, in order to save space and highlight the innovative elements of this patent, the working principle and process of how the driving wheel drives the driven wheel to rotate are not described in this patent.
[0023] During use, the waste concrete is added to the feeding box 10. Under the action of gravity, the waste concrete squeezes open the cover plate 11. At this time, the cover plate 11 squeezes the support spring 15, causing the support spring 15 to deform, thereby opening the cover plate 11. Then, the waste concrete enters the upper ends of the first crushing roller 2 and the second crushing roller 5 through the feeding box 10. After the feeding is completed, the support spring 15 returns to its original state, which can support the cover plate 11 and close the cover plate 11. Then, the driving wheel 3 is rotated by a motor. The first crushing roller 2 is driven to rotate by the driving wheel 3. When the driving wheel 3 rotates, it can drive the driven wheel 6 to rotate. The second crushing roller 5 can be driven by the driven wheel 6. The waste concrete can be well crushed by the first crushing roller 2 and the second crushing roller 5.
[0024] Please refer to Figure 2 , a first crushing gear 201 is arranged around the outer wall of the first crushing roller 2. The first crushing gear 201 and the first crushing roller 2 are of an integral structure. A second crushing gear 501 is arranged around the outer wall of the second crushing roller 5. The second crushing gear 501 and the second crushing roller 5 are of an integral structure. This can make the structure between the first crushing gear 201 and the first crushing roller 2 more firm, and can make the structure between the second crushing gear 501 and the second crushing roller 5 more firm. By arranging the first crushing roller 2 and the second crushing roller 5, the waste concrete can be conveniently and quickly crushed for recycling and reuse.
[0025] Please refer to Figure 1 and Figure 2, the auxiliary limit seat 7 is arranged corresponding to the first crushing roller 2 and the second crushing roller 5. The auxiliary limit seat 7 and the crushing device box 1 are fixedly connected by fixing bolts 8, which can facilitate the installation and fixation between the auxiliary limit seat 7 and the crushing device box 1. The installed auxiliary limit seat 7 can block the waste concrete, so that the waste concrete will not fall from both sides of the first crushing roller 2 and the second crushing roller 5, and at the same time will not affect the crushing effect of the first crushing roller 2 and the second crushing roller 5.
[0026] Please refer to Figure 1 , a stable support frame 9 is installed at the lower end of the crushing device box 1. The stable support frame 9 and the crushing device box 1 are welded together, which can make the structure between the stable support frame 9 and the crushing device box 1 more firm. The set stable support frame 9 can stably support the crushing device box 1.
[0027] Please refer to Figure 1 and Figure 3 , the feed box 10 and the crushing device box 1 are welded together. An inclined chute 1001 is arranged at the lower end inside the feed box 10, which can make the structure between the feed box 10 and the crushing device box 1 more firm. Through the set inclined chute 1001, the falling waste can be buffered.
[0028] Please refer to Figure 1 、 Figure 3 and Figure 4 , there are two cover plates 11. The cover plates 11 and the feed box 10 are rotatably connected by rotating hinges 12. Through this setting, the cover plates 11 and the feed box 10 can rotate relative to each other.
[0029] Please refer to Figure 3 and Figure 4 , a fixing foot 1301 is arranged at the lower end of the fixing seat 13. The fixing foot 1301 and the mounting seat 1002 are fixedly connected by fixing screws 14. There are eight support springs 15, and the eight support springs 15 are symmetric about the vertical center line of the feed box 10, which can facilitate the installation and fixation between the fixing seat 13 and the mounting seat 1002. The support springs 15 can support the lower end of the cover plate 11. When the cover plate rotates under the extrusion of the waste, the support springs 15 can reset the cover plate 11.
[0030] Working principle: When in use, by adding waste concrete into the feeding box 10, under the action of gravity, the waste concrete squeezes open the cover plate 11. At this time, the cover plate 11 squeezes the supporting spring 15, causing the supporting spring 15 to deform, so that the cover plate 11 opens. Then, the waste concrete enters the upper ends of the first crushing roller 2 and the second crushing roller 5 through the feeding box 10. After the feeding is completed, the supporting spring 15 returns to its original state, which can support the cover plate 11 and close the cover plate 11. Then, the motor is used to rotate the driving wheel 3, and the driving wheel 3 drives the first crushing roller 2 to rotate. When the driving wheel 3 rotates, it can drive the driven wheel 6 to rotate, and the driven wheel 6 can drive the second crushing roller 5. The first crushing roller 2 and the second crushing roller 5 can well crush the waste concrete. During the crushing process, the crushed concrete may splash or generate a large amount of dust. The closed cover plate 11 can prevent the crushed concrete from splashing, thus avoiding the possible harm to the staff caused by the splashing concrete. The installed baffle 17 can well block the scattering of dust during the crushing process and avoid environmental pollution.
[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
