The overall idea is as follows:

[0022] In view of the problems existing in the prior art, the utility model provides a feeding structure of a rotary kiln, including a rotary kiln body 31, wherein the right end of the rotary kiln body 31 is connected to a feeding box 11 through an input pipe, and a feeding port 12 is provided at the left end of the feeding box 11, and the feeding box 11 is connected to the interior of the rotary kiln body 31 through the provided feeding port 12, wherein a raised platform 21 is fixedly installed at the bottom of the inner wall of the feeding box 11, and an inclined slot 22 is provided at the upper end of the raised platform 21, wherein two rectangular holes are provided through the left end of the feeding box 11, and fans 13 are fixedly installed in the two rectangular holes provided in the feeding box 11, wherein a vibration motor 16 is fixedly installed at the rear end of the feeding box 11, and when the rotary kiln is being fed, the user feeds the inner wall of the feeding box 11 through the feeding port 14 provided in the feeding box 11, and while feeding, the user turns on the two fans 13 so that the two fans 13 work to move toward Air is blown in the direction of the slag discharge channel 15. At this time, the material added to the feeding box 11 will be blown by the two fans 13, and some light fine particles will be blown in the direction of the slag discharge channel 15, while those with good quality will continue to fall towards the position of the filter screen 17. At this time, the vibration motor 16 works, and drives the connecting shaft 19 and the filter screen 17 to vibrate through the output shaft. During the vibration process, the material particles are screened, and some larger materials that have not been crushed are left on the upper end of the filter screen 17, so as to facilitate the subsequent crushing of these larger material particles. The material particles falling from the filter screen 17 will automatically fall into the interior of the rotary kiln body 31 under the design of the upper bevel of the elevated platform 21, so that they can be processed by the rotary kiln body 31, and the fine particles filtered out by the two fans 13 will be discharged outward through the interior of the slag discharge channel 15 for treatment.

[0023] A connecting shaft 19 is installed at the front end of the vibration motor 16 through the output shaft, and a filter screen 17 is fixedly installed through the middle circumferential surface of the connecting shaft 19, and baffles 18 are fixedly installed on both sides of the upper end of the filter screen 17. A feeding hole 14 is opened at the upper end of the feeding box 11, wherein a slag discharge channel 15 is provided at the right end of the feeding box 11, and the interior of the slag discharge channel 15 is connected with the interior of the feeding box 11, wherein the slag discharge channel 15 is aligned parallel to the two fans 13. The present invention uses two fans 13 arranged at the side ends of the feeding box 11 and the slag discharge channel 15 to enable the device to rotate the rotary kiln body 31 When feeding, some lighter fine particles and impurities in the material particles can be discharged and will not fall into the interior of the rotary kiln body 31, thereby ensuring the efficiency and level of the processing of the rotary kiln body 31. The new device can perform secondary screening on the added materials by setting the vibration motor 16, the filter screen 17 and the connecting shaft 19, so that the larger particles can be filtered out, and then taken out for secondary crushing and added to the interior of the rotary kiln body 31 for processing, which will not cause waste of materials and greatly save the cost of processing the rotary kiln body 31.

[0024] Working principle:

[0025] In the first step, when the rotary kiln is feeding, the user feeds the material to the inner wall of the feeding box 11 through the feeding hole 14 provided in the feeding box 11. While feeding, the user turns on the two fans 13, so that the two fans 13 work and blow air toward the direction of the slag discharge channel 15. At this time, the material added to the feeding box 11 will be blown by the two fans 13, and some lighter fine particles will be blown toward the direction of the slag discharge channel 15, while those with better quality will continue to fall toward the position of the filter screen 17. At this time, the vibration motor 16 works, and drives the connecting shaft 19 and the filter screen 17 to vibrate through the output shaft. In the process of vibration, the material particles are screened, and some larger materials that have not been crushed are left at the upper end of the filter screen 17, so as to facilitate the subsequent crushing of these larger material particles, and the material particles falling from the filter screen 17 will be automatically The two fans 13 and the slag discharge channel 15 are arranged at the side ends of the feeding box 11, so that the lighter fine particles and impurities in the material particles can be discharged when the rotary kiln body 31 is fed, and the impurities will not fall into the interior of the rotary kiln body 31, thereby ensuring the efficiency and level of the processing of the rotary kiln body 31. The vibration motor 16, the filter screen 17 and the connecting shaft 19 are arranged in the present invention, so that the device can perform secondary screening on the added material, so that larger particles can be filtered out, and then taken out for secondary crushing and added to the rotary kiln body 31 for processing, which will not cause waste of materials and greatly save the cost of processing the rotary kiln body 31.

[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
