[0018] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.
[0019] like Figures 1-4As shown, the embodiment of the utility model provides a waste sand recycling grinding device, including a body 1, a fixing frame 4 is installed on the top of the body 1, and the installation of the driving motor 3 is completed through the fixing frame 4. The body 1 is a frame structure, and a grinding plate 7 is provided on the top of the body 1. The grinding plate 7 is an arc-shaped plate, which is convenient for the input of foundry sand, and the grinding plate 7 is provided with a plurality of filtering holes along the extension direction, which is convenient for the foundry sand that meets the requirements to pass through during the grinding process and to separate the foundry sand that does not meet the requirements. A driving motor 3 is installed on one side of the fixing frame 4, and a rotating shaft 5 is installed at the output end of the driving motor 3. Support plates 9 are installed at the bottom of both sides of the rotating shaft 5, and grinding rollers 6 are fixed between the bottoms of the support plates 9. The grinding rollers 6 can be driven to move on the grinding plate 7 by the rotation of the driving motor 3. The grinding rollers 6 are provided with protrusions to improve the grinding effect of the foundry sand. An oscillating grinding mechanism is provided between the grinding plate 7 and the body 1.
[0020] Specifically, the driving motor 3 is a stepping motor, and the moving trajectory of the grinding roller 6 is the same as the arc of the grinding plate 7, which facilitates the grinding operation of the foundry sand.
[0021] In this embodiment, the oscillating grinding mechanism includes a support column 13, a fixed plate 14, a spring 15 and a limit column 16. The support column 13 is installed at the four corners of the bottom of the body 1, and the fixed plate 14 is installed between the tops of the support columns 13. One end of the spring 15 is evenly arranged along the length of the fixed plate 14, and the other end is fixed to the bottom of the grinding plate 7. One end of the limit column 16 is installed at the bottom of the grinding plate 7, and the other end passes through the fixed plate 14. The limit column 16 and the spring 15 are located on both sides of the fixed plate 14. The support column 13 and the spring 15 can complete the support of the grinding plate 7, and the setting of the limit column 16 can prevent the grinding plate 7 from shaking left and right inside the body 1, so that the grinding plate 7 can only vibrate up and down along the limit column 16 during the grinding operation, thereby facilitating the grinding operation.
[0022] Specifically, an anti-drop cover 17 is installed at one end of the limiting column 16 that passes through the fixing plate 14 to prevent the grinding plate 7 from falling off the limiting column 16 .
[0023] Specifically, connecting plates 11 are installed on both sides of the support plate 9, and scrapers 10 are installed between the bottoms of the connecting plates 11. A plurality of comb plates 12 are evenly arranged along the length of the bottom of the scraper 10. The arrangement of the scraper 10 facilitates the scraping of the casting sand and facilitates the grinding operation.
[0024] Specifically, a sealing door 2 is installed on one side of the bottom of the machine body 1, and a guide plate 8 is installed on the bottom of the machine body 1. The guide plate 8 is a wedge-shaped plate and is connected to the sealing door 2 at an oblique lower end to facilitate the collection of the ground foundry sand.
[0025] Working principle: The operator introduces the foundry sand to be ground onto the grinding plate 7, and then starts the drive motor 3. The drive motor 3 drives the grinding roller 6 to roll along the grinding plate 7 through the rotating shaft 5. The drive motor 3 drives the rotating shaft 5 and the grinding roller 6 to move back and forth along the grinding plate 7, and when the grinding roller 6 moves, since the grinding roller 6 is fixedly connected to the support plate 9, the grinding roller 6 is in direct contact with the foundry sand, and the foundry sand can be directly crushed and ground. The drive motor drives the grinding roller 6 to grind the foundry sand, and during the grinding operation, the grinding plate 7 under pressure can press down the spring 15 to contract, and repeatedly contract and rise under the rebound of the spring 15, causing its vibration, so that the position of the foundry sand on the grinding plate 7 changes, thereby facilitating the improvement of the grinding efficiency. The ground foundry sand flows to the sealing door 2 through the guide plate 8 for subsequent collection.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
