Description

Technical Field

[0001] The utility model relates to the technical field of screw coal feeders, in particular to an anti-jamming screw coal feeder. Background Art

[0002] The existing screw coal feeder is composed of a closed feed barrel and a conveying screw inside. Since the feed barrel of the screw coal feeder is fully enclosed and there is mostly no dredging device at the feed inlet, the coal material will be blocked due to excessive feeding. During long-term operation, it will adhere, accumulate and caking inside the feed barrel, increasing the wear of the conveying screw and the coal feeding resistance. Especially when the coal material is damp and caked, the conveying screw will be stuck by the caked hard coal material, and it is necessary to disassemble the conveying screw to dredge the coal material in the feed barrel, which is time-consuming and laborious. Therefore, an anti-jamming screw coal feeder is designed to solve the above problems. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing screw coal feeder, the purpose of the utility model is to provide an anti-jamming screw coal feeder, which has the advantages of dredging the incoming coal material, dredging the stuck coal material in the feed barrel, etc.

The crushing assembly 4 is arranged on the outer wall of the top 6 of the feed cylinder 2, and the crushing assembly 4 is used to crush the caked coal in the feed cylinder 2. The stirring assembly 5 and the linkage assembly 7 are arranged on the side wall of the feed hopper 6. The stirring assembly 5 is used to stir the coal in the feed hopper 6 to prevent blockage, and the linkage assembly 7 is used to transmit the power of the conveying screw 3 to the stirring assembly 5;

[0020] The crushing assembly 4 includes a cylinder 41, a vibration motor 42, a gantry 43, a substrate 44, a flexible plastic rod 45, a buffer rubber pad 46 and a metal crushing head 47. The gantry 43 is fixedly connected to the outer wall of the feed cylinder 2. The middle of the gantry 43 is fixedly connected with the cylinder 41. The substrate 44 is fixedly connected to the telescopic end of the cylinder 41 through the buffer rubber pad 46. The vibration motors 42 are arranged on both sides of the top of the substrate 44. A plurality of flexible plastic rods 45 penetrating the outer wall of the feed cylinder 2 are arranged at equal intervals at the bottom of the substrate 44. The bottom end of the flexible plastic rod 45 is provided with a metal crushing head 47, and the flexible plastic rod 45 moves out of the feed cylinder 2 when the conveying screw 3 works;

[0021] The bottom end face of the metal crushing head 47 is conical;

[0022] The flexible plastic rod 45 has the characteristic of being bendable and recoverable; when the flexible plastic rod 45 extends into the barrel 2 to crush the caked coal material, the flexible plastic rod 45 is not subject to radial force and thus will not bend; when the flexible plastic rod 45 abuts against the conveying screw 3, since the conveying screw 3 is made of metal and has a curvature, the flexible plastic rod 45 is forced to bend under the radial force, thereby preventing the conveying screw 3 from being damaged by the crushing head;

[0023] The stirring assembly 5 includes a stirring rod 51, a rotating seat 52 and a driven bevel gear 53. The rotating seat 52 is rotatably connected to the side wall of the feed hopper 6. The rotating seat 52 is inclined with a stirring rod 51 corresponding to the inner end face of the feed hopper 6. The other end face of the rotating seat 52 is fixedly connected with a driven bevel gear 53;

[0024] The linkage assembly 7 includes a linkage rod 71, a driving bevel gear 72 and a transmission bevel gear 73. The driving bevel gear 72 is sleeved on the input shaft of the conveying screw 3. The linkage rod 71 is rotatably connected to the outer wall of the feed hopper 6. Both ends of the linkage rod 71 are provided with transmission bevel gears 73.

[0025] Through the above settings, in the actual working process, its specific working principle is as follows:

[0026] When the spiral coal feeder works, the driving motor 8 is started. The power output by the driving motor 8 drives the conveying screw 3 to rotate through the reducer 9, so as to convey the coal material by the conveying screw 3;

[0027] In the above process, the rotating conveying screw 3 drives the driving bevel gear 72 to rotate at the same time. The power of the driving bevel gear 72 is transmitted to the driven bevel gear 53 through the linkage rod 71 and the transmission bevel gear 73. The driven bevel gear 53 drives the rotating seat 52 and the stirring rod 51 located in the feed hopper 6 to rotate. The rotating stirring rod 51 continuously stirs the coal material in the feed hopper 6, so as to crush and dredge the caked coal material in the feed hopper 6, facilitating the conveying operation of the conveying screw 3;

[0028] When the conveying screw 3 is stuck by the caked coal material, the air cylinder 41 and the vibration motor 42 are started. The air cylinder 41 extends to drive the flexible plastic rod 45 to extend into the barrel 2. The vibration motor 42 forces the metal crushing head 47 at the bottom end of the flexible plastic rod 45 to swing at a high frequency, so as to facilitate the metal crushing head 47 to insert into the caked coal material for crushing and dredging. During this process, the driving motor 8 drives the conveying screw 3 to rotate forward and backward, so as to assist the metal crushing head 47 to crush the caked coal material. Thus, when dredging the coal material in the barrel 2, it is not necessary to disassemble the conveying screw 3, achieving the effect of saving time and effort;
