Description

Technical Field

[0001] This utility model relates to the field of casting production technology, and in particular to a casting sand removal device for casting production and processing. Background Technology

[0002] Existing casting sand removal devices for casting production and processing are used to crush molding sand, breaking larger sand blocks into smaller particles. This facilitates subsequent regeneration and reuse of the molding sand, saving raw materials. However, these devices lack any noise reduction components, resulting in significant noise during sand removal. For example, a Chinese patent discloses a "casting sand removal device for casting production and processing" (application number "202221451768.7"). This device uses a drive motor to drive opposing rotating gears, which in turn drive opposing crushing rollers to crush lumps in the sand. This provides better pulverization of lumps, facilitating subsequent processing. However, the crushing process generates significant noise, and the lack of noise reduction components means workers are exposed to high-noise environments without effective sound insulation for extended periods. This can lead to hearing loss, tinnitus, and other problems, potentially impacting their health, quality of life, and work efficiency. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a casting sand removal device for casting production and processing. When the crushing roller crushes blocky molding sand, the rubber plate set inside the crushing box can effectively absorb the impact sound generated by the crushed molding sand splashing onto the inner wall of the crushing box, reducing the generation and propagation of noise. Through the multiple honeycomb holes set on the crushing box, the honeycomb holes have a sound absorption effect, and the porous structure scatters and absorbs sound waves, which can further reduce the sound transmitted from the crushing box. The crushing box is connected between the upper support plate and the lower support plate by springs and dampers, which can eliminate the vibration sound when the crushing box is working. The crushing box is connected between the upper support plate and the lower support plate by springs and dampers, which can effectively eliminate the vibration sound when the crushing box is working. Through the triple sound insulation effect, the noise generated by the equipment when processing molding sand can be effectively absorbed, isolated and attenuated, so as to significantly reduce the noise level of the workplace and the surrounding environment, creating a quieter and more comfortable working environment.

[0004] This utility model also provides a casting sand removal device for casting production and processing, comprising: a lower support plate, a support rod fixedly connected to the upper surface of the lower support plate, an upper support plate fixedly connected to the upper end of the support rod, springs fixedly connected to two opposite surfaces of the upper and lower support plates, dampers fixedly connected to two opposite surfaces of the upper and lower support plates, a crushing box fixedly connected between the springs and dampers, a crushing roller rotatably connected to the inner surface of the crushing box, multiple honeycomb holes provided on the crushing box, a rubber plate fixedly connected to the inner surface of the crushing box, a feeding box penetrating through the inner surface of the lower support plate, the feeding box communicating with the crushing box, a feed box penetrating through the inner surface of the upper support plate, the feed box communicating with the crushing box, multiple baffles fixedly connected to the inner surfaces of the feed box and the feeding box, the multiple baffles being inclined downward at a 15-degree angle, rubber strips fixedly connected to the outer walls of the feed box and the feeding box, the rubber strips being movably connected to the rubber plate.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model provides a casting sand removal device for casting production and processing, which includes: a lower support plate 4, a support leg 13 fixedly connected to the lower surface of the lower support plate 4, a reinforcing rod 14 fixedly connected to the side surface of the support leg 13, a rotating shaft 15 rotatably connected to the lower surface of the support leg 13, a bracket 16 fixedly connected to the side surface of the rotating shaft 15, a rotating wheel 17 rotatably connected to the inner surface of the bracket 16, and a protective sleeve 18 fixedly connected to the outer surface of the rotating wheel 17.

[0022] Specifically: The lower surface of the lower support plate 4 is supported by the support leg 13, and the reinforcing rod 14 on the side surface of the support leg 13 enhances the stability of the support. At the same time, the rotating shaft 15, bracket 16, rotating wheel 17 and protective sleeve 18 on the lower surface of the support leg 13 form a moving mechanism, which facilitates the movement and handling of the equipment and allows the equipment to be flexibly adjusted in position according to production needs.

[0023] A support rod 3 is fixedly connected to the upper surface of the lower support plate 4. An upper support plate 1 is fixedly connected to the upper end of the support rod 3. A feed box 9 is connected through the inner surface of the upper support plate 1. A cover plate 8 is movably connected to the upper surface of the feed box 9. A handle 7 is fixedly connected to the upper surface of the cover plate 8. The feed box 9 is connected to the crushing box 2. Multiple baffles 22 are fixedly connected to the inner surfaces of both the feed box 9 and the discharge box 24. The multiple baffles 22 are all tilted downward at a 15-degree angle. Springs 11 are fixedly connected to the two opposite surfaces of the upper support plate 1 and the lower support plate 4. Dampers 10 are fixedly connected to the two opposite surfaces of the upper support plate 1 and the lower support plate 4. The crushing box 2 is fixedly connected between the springs 11 and the dampers 10. A crushing roller 23 is rotatably connected to the inner surface of the crushing box 2. A motor 12 is fixedly connected to the side surface of the crushing box 2. The crushing roller 23 is driven by the motor 12. Multiple honeycomb holes 21 are provided on the crushing box 2. A rubber plate 20 is fixedly connected to the inner surface of the crushing box 2.

[0024] Specifically: By opening the cover plate 8 through handle 7, the molding sand containing the casting to be processed is poured into the feed box 9. Under the action of gravity, the molding sand falls along the feed box 9. Since multiple downward-inclined baffles 22 are fixedly connected to the inner surface of the feed box 9, the baffles 22 make the falling path of the molding sand tortuous, slowing down the falling speed of the molding sand, and at the same time play a preliminary role in dispersing the molding sand, so that the molding sand enters the crushing box 2 more evenly. On the other hand, the baffles 22 can isolate sound to a certain extent and reduce noise transmission. The motor 12 is started, and the motor 12 drives the crushing roller 23 in the crushing box 2 to rotate. The molding sand entering the crushing box 2 is crushed into smaller pieces by the impact of the rotating crushing roller 23. The crushing chamber 2 is connected between the upper support plate 1 and the lower support plate 4 by spring 11 and damper 10. Spring 11 can play an elastic buffering role when the equipment is working, and damper 10 can consume vibration energy. The two work together to effectively eliminate the vibration generated when the crushing chamber 2 is working, thereby reducing the noise caused by vibration. During the crushing process, the rubber plate 20 inside the crushing chamber 2 can play a buffering role, reducing the impact sound generated by the molding sand splashing onto the inner wall of the crushing chamber 2, and also reducing the wear of molding sand on the chamber wall. The multiple honeycomb holes 21 set on the crushing chamber 2 have a sound absorption function. Its porous structure can scatter and absorb sound waves, further reducing the sound transmitted from the crushing chamber 2, and achieving the sound insulation effect.

[0025] The inner surface of the lower support plate 4 is connected to the feeding box 24. The lower surface of the feeding box 24 is fixedly connected to four support rods 5. The four support rods 5 are symmetrically arranged. The lower ends of the four support rods 5 are fixedly connected to the feeding plate 6. The feeding plate 6 is located below the feeding box 24. The feeding box 24 is connected to the crushing box 2. The outer walls of the feeding box 9 and the feeding box 24 are fixedly connected to rubber strips 19. The rubber strips 19 are movably connected to the rubber plate 20.

[0026] Specifically: The crushed molding sand falls downward through the feed box 24 connected to the crushing box 2. The multiple downward-sloping baffles 22 inside the feed box 24 can slow down the falling speed of the molding sand and disperse the molding sand, so that the molding sand falls more evenly on the feed plate 6, and can also isolate sound. The rubber strips 19 on the outer wall of the feed box 24 and the feed box 9 are movably connected to the rubber plate 20, which further enhances the sealing and sound insulation effect of the equipment and prevents molding sand leakage and noise transmission.

[0027] Working Principle: By opening the cover plate 8 with handle 7, the molding sand containing the castings to be processed is poured into the feed box 9. Under gravity, the molding sand falls along the feed box 9. Because multiple downward-sloping baffles 22 are fixedly connected to the inner surface of the feed box 9, the baffles 22, on the one hand, make the falling path of the molding sand tortuous, slowing down the falling speed, and simultaneously playing a preliminary dispersing role, allowing the molding sand to enter the crushing box 2 more evenly. On the other hand, the baffles 22 can isolate sound to a certain extent, reducing noise transmission. The motor 12 is started, driving the crushing rollers 23 inside the crushing box 2 to rotate. The molding sand entering the crushing box 2 is struck by the rotating crushing rollers 23, breaking larger sand blocks into smaller ones. The crushing chamber 2 is connected between the upper support plate 1 and the lower support plate 4 by spring 11 and damper 10. Spring 11 can play an elastic buffering role when the equipment is working, and damper 10 can consume vibration energy. The two work together to effectively eliminate the vibration generated when the crushing chamber 2 is working, thereby reducing the noise caused by vibration. During the crushing process, the rubber plate 20 inside the crushing chamber 2 can play a buffering role, reducing the impact sound generated by the molding sand splashing onto the inner wall of the crushing chamber 2, and also reducing the wear of molding sand on the chamber wall. The multiple honeycomb holes 21 set on the crushing chamber 2 have a sound absorption function. Its porous structure can scatter and absorb sound waves, further reducing the sound transmitted from the crushing chamber 2, and achieving the sound insulation effect.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
