Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1 to 5 , a ventilation grate plate for cooling materials, including a grate plate seat 1. At the four corners of the grate plate seat 1, a cylindrical telescopic rod 2 is fixedly connected. The upper end of the cylindrical telescopic rod 2 is fixedly connected with a grate plate frame 3. A plurality of grate bars 4 are fixedly connected in the grate plate frame 3. A shock absorption mechanism 5 is fixedly connected between the grate plate seat 1 and the grate plate frame 3. A sealing plate 6 is fixedly connected to the front end of the grate plate seat 1. The sealing plate 6 is provided with an air inlet pipe. A cleaning assembly 7 is arranged on the upper surface of the grate plate seat 1. The end of the grate plate frame 3 is rotatably connected with a sealing assembly 8. A limiting assembly 9 for limiting the sealing assembly 8 is arranged at the end of the grate plate frame 3.

[0022] A ventilation grate plate for cooling materials in the present invention is similar in structure to the existing ventilation grate plate for cooling materials. For example, the patent with the publication number CN220507724U discloses a ventilation grate plate for cooling materials. The main improvement points of the present invention are as follows: through the action of the shock absorption spring 503, the impact of the materials on the grate bars 4 is reduced, thereby prolonging the service life of the grate bars 4. Moreover, it can also clean the small materials or particles accumulated on the grate plate seat 1, thereby ensuring the cleanliness of the grate plate seat 1 and ensuring the normal circulation of the cold air above the grate plate seat 1. Such as Figures 1 to 5As shown in the figure, when the ventilation grate plate for cooling materials in the present utility model is cooling the materials, the materials fall from a high place onto the grate bars 4. Under the action of the shock-absorbing springs 503, the impact force of the materials on the grate bars 4 is absorbed, thereby reducing the impact force of the materials on the grate bars 4, protecting the grate bars 4 and extending the service life of the grate bars 4. When the ventilation grate plate stops being used, the restriction of the tightening bolt 901 on the stop block 902 is released, and the stop block 902 is turned to the vertically downward state, so that the stop block 902 no longer restricts the cover plate 803. At this time, the multi-stage electric telescopic rod 701 is started, and the multi-stage electric telescopic rod 701 becomes longer, thereby pushing the scraper 702 to move along the surface of the grate plate seat 1, so as to scrape off the particulate matters or small materials on the grate plate seat 1 until the push rod 703 fixed on the scraper 702 jacks up the cover plate 803, and the cover plate 803 rotates upward around the rotating shaft 802, so that the small materials or particulate matters can fall from the end of the grate plate seat 1, thereby cleaning the grate plate seat 1. After the cleaning is completed, the multi-stage electric telescopic rod 701 is retracted according to the reverse operation, and the cover plate 803 can re-seal the ends of the grate plate seat 1 and the grate plate frame 3, and the stop block 902 is turned to the horizontal state, and then the tightening bolt 901 is tightened to continue the cooling work.

[0023] As Figure 2 shown, the shock-absorbing mechanism 5 includes an outer plate 501 fixed on the lower surface of the grate plate frame 3. An inner plate 502 is slidably connected inside the outer plate 501. Both sides of the upper surface of the grate plate seat 1 are fixedly connected with shock-absorbing springs 503, and the output ends of the shock-absorbing springs 503 are fixedly connected with the grate plate frame 3.

[0024] Specifically, when cooling the materials, the materials fall from a high place onto the grate bars 4. Under the action of the shock-absorbing springs 503, the impact force of the materials on the grate bars 4 is absorbed, thereby reducing the impact force of the materials on the grate bars 4, protecting the grate bars 4 and extending the service life of the grate bars 4. During this process, the outer plate 501 also moves downward, and the outer plate 501 and the inner plate 502 seal the left and right sides of the grate plate seat 1 and the grate plate frame 3.

[0025] As Figure 3 shown, the cleaning assembly 7 includes two multi-stage electric telescopic rods 701 fixed on the outer surface of the sealing plate 6. The output ends of the two multi-stage electric telescopic rods 701 pass through the inner surface of the sealing plate 6. The output ends of the two multi-stage electric telescopic rods 701 are fixedly connected with a scraper 702, and a push rod 703 is fixedly connected to the surface of the scraper 702.

[0026] Specifically, after the cooling operation stops, the multi-stage electric telescopic rod 701 is activated. The multi-stage electric telescopic rod 701 extends, thereby pushing the scraper 702 to move along the surface of the grate seat 1, so as to scrape off the particulate matter or small materials on the grate seat 1 until the push rod 703 fixed on the scraper 702 lifts the cover plate 803. The cover plate 803 rotates upward around the rotating shaft 802, so that the small materials or particulate matter can fall from the end of the grate seat 1.

[0027] As Figure 5 shown, the sealing assembly 8 includes a groove 801 opened at the end of the grate frame 3. A rotating shaft 802 is rotatably connected in the groove 801, and a cover plate 803 is fixedly connected to the rotating shaft 802.

[0028] Specifically, when cleaning work is carried out, after the push rod 703 contacts the cover plate 803 and continues to move, the cover plate 803 can be rotated upward around the rotating shaft 802, so as to open the end of the grate seat 1 and the grate frame 3, thus facilitating the scraper 702 to push the small materials or particulate matter out from the end of the grate seat 1.

[0029] As Figure 4 shown, the limiting assembly 9 includes a tightening bolt 901 threadedly connected to the end of the grate frame 3, and a stopper 902 is sleeved on the tightening bolt 901.

[0030] Specifically, when cleaning work needs to be carried out, first release the restriction of the tightening bolt 901 on the stopper 902, and turn the stopper 902 to a vertically downward state, then the restriction on the cover plate 803 can be released, so that the cover plate 803 can rotate under the action of the push rod 703. After the cleaning is completed, the cover plate 803 can be fixed by operating in the reverse order, so as to continue the cooling operation.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
