[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: it includes an outer casing 1 and an inner cylinder 2, and the inner cylinder 2 is rotatably arranged inside the outer casing 1 through a bearing; It also includes: The base 3 is hinged to the bottom of the outer casing 1, and an electric push rod 4 is hinged inside the base 3. The upper end of the electric push rod 4 is hinged to the outer casing 1. The feeding hopper 5 is suspended on the front side of the inner cylinder 2. A rotating frame 6 is fixedly installed on the left side wall of the feeding hopper 5. Two connecting blocks 7 are fixedly installed on the front side wall of the outer box 1. The rotating frame 6 is rotatably connected to the two connecting blocks 7 through bearings. The outer box 1 is provided with a synchronous flipping mechanism 8 connected to the rotating frame 6. A handle 14 is fixedly installed on the front side wall of the feeding hopper 5. A latch 15 connected to the outer box 1 is provided on the feeding hopper 5. When it is necessary to maintain the inside of the inner cylinder 2, the feeding hopper 5 can be flipped more conveniently through the handle 14, which improves the convenience of opening the front opening of the inner cylinder 2. A guide plate 13 is fixedly installed inside the feeding hopper 5 and is located in the opening of the inner cylinder 2. The guide plate 13 can provide guidance for the feeding of the inner cylinder 2 and prevent the material from accumulating or scattering in the gap between the inner cylinder 2 and the feeding hopper 5. A fixed shell 9 is fixedly installed on the rear side wall of the outer box 1. A motor 10 is fixedly installed inside the fixed shell 9. A scraping mechanism 11 connected to the motor 10 is provided on the inner cylinder 2. The synchronous flipping mechanism 8 includes: Drive rod 8-1, the drive rod 8-1 is fixedly installed at the bottom of the rotating frame 6, the lifting bar 8-2 is movably sleeved on the drive rod 8-1, and the guide block 8-4 is movably installed in the rotating guide groove 8-3 opened on the drive rod 8-1, and the guide block 8-4 is fixedly installed on the inner wall of the lifting bar 8-2. The slide rail frame 8-5 is fixedly installed on the front side wall of the outer housing 1. A slider 8-6 is slidably installed inside the slide rail frame 8-5, and the slider 8-6 is fixedly connected to the rear side wall of the lifting bar 8-2. A spring 8-7 connected to the slider 8-6 is fixedly installed inside the slide rail frame 8-5. A fixed plate 8-8 is fixedly installed on the front side wall of the base 3. A vertical rod 8-9 is fixedly installed at the lower end of the lifting bar 8-2. A roller 12 is provided at the lower end of the vertical rod 8-9. The roller 12 is movably abutting against the fixed plate 8-8. The roller 12 can prevent the lower end of the vertical rod 8-9 from directly abutting against the fixed plate 8-8 and causing wear, effectively improving the service life of the vertical rod 8-9 and the fixed plate 8-8. When the outer box 1 and the inner cylinder 2 are flipped forward, the feeding hopper 5 can be automatically flipped by the synchronous flipping mechanism 8, opening the front opening of the inner cylinder 2 and improving the convenience of material discharge. The wall scraping mechanism 11 includes: The scraper strips 11-1, there are several scraper strips 11-1, which are movably abutting inside the inner cylinder 2 with equal rounded corners. A rotating plate 11-2 is fixedly installed on the rear side of the scraper strips 11-1. A rotating rod 11-3 is fixedly installed on the rear side wall of the rotating plate 11-2, and the rotating rod 11-3 is rotatably inserted through the rear side wall of the inner cylinder 2 through a bearing. Rotary sleeve 11-4 is rotatably inserted into the rear side wall of outer housing 1 via bearing, and is rotatably sleeved on rotating rod 11-3 via bearing. A first bevel gear 11-5 is fixedly sleeved on the output shaft of motor 10, and rotating sleeve 11-4 is fixedly installed on the rear side wall of inner cylinder 2. The second bevel gear 11-6 is fixedly sleeved on the rear end of the rotating rod 11-3. The rear end of the rotating sleeve 11-4 is fixedly sleeved with the third bevel gear 11-7. Both the second bevel gear 11-6 and the third bevel gear 11-7 are meshed with the first bevel gear 11-5. When the inner cylinder 2 is driven to rotate by the motor 10, the first bevel gear 11-5 and the third bevel gear 11-7, the meshing of the second bevel gear 11-6 and the first bevel gear 11-5 enables the rotating plate 11-2 to drive the scraper strip 11-1 to rotate synchronously in opposite directions inside the inner cylinder 2. This is to achieve material turning inside the inner cylinder 2 while also preventing the material from sticking to the inner wall of the inner cylinder 2.

[0019] When using this invention, the material is fed into the inner cylinder 2 through the feed hopper 5. The inner cylinder 2 heats and calcines the material. Simultaneously, the motor 10 is started, driving the first bevel gear 11-5 to rotate. With the cooperation of the second bevel gear 11-6 and the third bevel gear 11-7, the rotating rod 11-3 and the rotating sleeve 11-4 can rotate synchronously in opposite directions. The rotating sleeve 11-4 drives the inner cylinder 2 to rotate, and the rotating rod 11-3, through the rotating plate 11-2, drives the scraper strip 11-1 to rotate in opposite directions within the inner cylinder 2. This not only achieves material turning within the inner cylinder 2, improving the uniformity of material heating, but also avoids… The material adheres and clumps on the inner wall of the inner cylinder 2. When the material needs to be discharged after calcination, the latch 15 can be opened and the electric push rod 4 can be activated to extend it. At this time, the outer box 1 drives the inner cylinder 2 to flip forward, making it tilted downward. During this process, the roller 12 will roll on the fixed plate 8-8 and the vertical rod 8-9 will be squeezed upward. The vertical rod 8-9 drives the lifting bar 8-2 to move upward. By utilizing the movement of the guide block 8-4 in the rotating guide groove 8-3, the drive rod 8-1 can drive the rotating frame 6 to flip. The rotating frame 6 drives the feed hopper 5 to flip and open the front opening of the inner cylinder 2 for material discharge.

[0020] Compared with the prior art, the beneficial effects of this utility model are: Through the hinge structure between the base 3 and the outer box 1, the tilt adjustment design of the electric push rod 4, and the cooperation of the synchronous flipping mechanism 8, not only can the outer box 1 and the inner cylinder 2 be flexibly tilted for material discharge, but the front opening of the inner cylinder 2 can also be quickly opened by the flipping feed hopper 5, which greatly improves the convenience of material discharge. With the help of the scraping mechanism 11 driven by the motor 10, the first bevel gear 11-5 meshes with the second bevel gear 11-6 and the third bevel gear 11-7 respectively, so as to realize the rotation of the inner cylinder 2 and the synchronous rotation of the scraper 11-1 in opposite directions. This not only enhances the mixing effect of the material, but also cleans the inner wall of the inner cylinder 2 in real time through the scraper 11-1, effectively preventing the material from sticking and caking, and ensuring the uniformity of the calcination reaction and the stability of product quality. The roller 12 can prevent the lower end of the vertical rod 8-9 from directly contacting and moving on the fixed plate 8-8, thus avoiding wear and effectively improving the service life of the vertical rod 8-9 and the fixed plate 8-8. The guide plate 13 can guide the feeding of the inner cylinder 2, and prevent the material from accumulating or scattering in the gap between the inner cylinder 2 and the feed hopper 5.

[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
