DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0020] Please refer to Figures 1-4 , a double-cone rotary dryer with an auxiliary blanking device, including a support assembly, a bottom plate 1, a drying assembly and an auxiliary fixing member. A support assembly is provided below the bottom plate 1. The drying assembly includes a drying box 2, side plates 3, a feed cover 4, a discharge pipe 5 and a switching valve 6. The side plates 3 are in an inverted L shape, and two groups of side plates 3 are symmetrically arranged on the bottom plate 1. The left and right sides of the drying box 2 are rotatably connected to the upper parts of the side plates 3. The upper and lower sides of the drying box 2 are respectively provided with a feed cover 4 and a discharge pipe 5. A switching valve 6 is also provided on the discharge pipe 5. The auxiliary fixing member includes a protective cover 7, a bracket 8, a left and right hand screw 9, a worm gear 10, a worm 11, a motor 12, a support frame 13 and a clamping frame 14. Protective covers 7 and brackets 8 are symmetrically arranged on the left and right sides above the bottom plate 1. A worm 11 and two groups of worm gears 10 are arranged in the protective cover 7. The worm 11 meshes with the worm gear 10. The output end of the motor 12 penetrates through the protective cover 7 and is connected to the worm 11. One end of the left and right hand screw 9 is rotatably connected to the bracket 8, and the other end of the left and right hand screw 9 penetrates through the protective cover 7 and is connected to the center of the worm gear 10. The support frame 13 is in a U shape with an open top, and two groups of support frames 13 are symmetrically arranged. Screw holes adapted to the left and right hand screw 9 are provided on the front and rear sides of the bottom wall of the support frame 13. Clamping frames 14 for clamping the side wall of the drying box 2 are provided at the two free ends above the support frame 13.

[0021] During actual use, the support assembly provides stable support for the bottom plate 1, and the side plates 3 above the bottom plate 1 provide stable support for the drying box 2. Open the feed cover 4, close the switching valve to complete feeding, and then close the feed cover 4. The drying box 2 completes the rotary drying operation driven by an external driving device. The above driving device is a structure well-known to those skilled in the art and will not be elaborated herein. This article aims to provide a double-cone rotary dryer with an auxiliary blanking structure. Initially, when the drying box 2 rotates, the distance between the two support frames 13 is relatively large. When the drying box 2 completes the drying operation and the discharge pipe 5 is located below, in order to prevent the drying box 2 from rotating, start the motor 12. The motor 12 drives the worm 11 to rotate, the worm gear 10 drives the left and right hand screw 9 to rotate, the support frame 13 drives the clamping frame 14 to move towards each other, and the clamping frame 14 contacts the drying box 2 to prevent it from shaking. A buffer pad 18 is provided on the side of the clamping frame 14 close to the drying box 2 to ensure the stability of clamping. The motor 12 uses a servo motor 12 with stable operation.

[0022] During actual use, due to the unevenness of the ground, a support component is required to assist in adjusting the support to ensure the stability of the support of the bottom plate 1. The support component includes a U-shaped auxiliary frame 15, a support leg 16, and a fixing block 17. Two groups of the auxiliary frames 15 are symmetrically arranged below the bottom plate 1. A support leg 16 with a fixing block 17 is further arranged below the auxiliary frame 15. The support leg 16 is a stud, and the stud-structured support leg 16 is threadedly connected to the bottom wall of the auxiliary frame 15, which is convenient for adjusting the support height. A through hole is also provided in the center of the bottom plate 1, which is located between two groups of left-hand and right-hand threaded screws 9 to ensure the stability of the material feeding.
