Description

Technical Field

[0001] The invention belongs to the technical field of vibrating feeding equipment, and in particular relates to a vortex arch-breaking vibrating feeder with a self-locking function. Background Art

[0002] In the powder material transportation in coal mining, metallurgy, construction and other industries, due to the high water content of the powder material, the material arching and blockage often occur at the material outlet of the storage bin, resulting in the storage material being unable to fall into the conveyor belt or the conveying vehicle, interrupting the material transportation. The existing vibrating feeding equipment does not solve the technical problem of arching and blockage well.

[0003] The current vortex-type vibrating feeding equipment consists of a vibrating motor, a bucket, an activation cone, an activation cone base and a vibration isolation device. The vibrating motor drives the bucket to make each point of the bucket perform a spiral reciprocating motion. The material is subjected to both vertical and circumferential forces, thereby achieving the purpose of arch-breaking feeding. This type of vibrating feeding equipment has a simple structure and can complete general feeding tasks. Its shortcomings are poor arch-breaking ability, insufficient reliability, low working efficiency, and is only suitable for some materials with a small arch tendency.

[0004] The patent with the authorization announcement number CN 207843939U previously applied by the applicant discloses a vortex arch-breaking feeder, which includes a lower hopper and a support cone arranged on the top of the lower hopper. The arch-breaking cone is arranged at the center of the inner side of the lower hopper through a support beam fixed on the conical hole wall of the lower hopper. The top of the arch-breaking cone is placed in the support cone. Two vibration motors with adjustable inclination angles are arranged on the support beam outside the lower hopper. The two vibration motors are cross-arranged 180° symmetrically and run in opposite directions to form vortex-type vibration. Compared with the prior art, the present invention has the advantages of multi-point arch breaking, eradicating arch knots and wall hanging caused by arch knots, high arch breaking efficiency, small body wear and uninterrupted material transportation.

[0005] However, when the vortex arch-breaking feeder is used in a storage bin, a gate needs to be set on the horizontal bracket at the material drop port of the lower hopper to control the material drop conveying of the feeder; when the vortex arch-breaking feeder is used in a coal storage yard, a gate needs to be set on the support platform at the material drop port of the lower hopper to control the material drop conveying of the feeder. It can be seen that the vortex arch-breaking feeder designed in the early stage does not have a self-locking function, that is, it cannot automatically stop dropping after the vibration motor stops running. Therefore, according to the customer's usage requirements, it is necessary to improve the existing vortex arch-breaking feeder to realize its self-locking function. Summary of the invention

[0006] The technical problem solved by the present invention is to provide a vortex arch-breaking feeder with a simple structure and reasonable design and a self-locking function, which effectively solves the technical problem of material transportation interruption caused by arching and blockage of stored materials and coal yard materials, and the vortex arch-breaking feeder has a self-locking function, that is, the feeder automatically stops dropping materials after the vibration motor stops running.

[0007] In order to solve the above technical problems, the present invention adopts the following technical scheme: a vortex arch-breaking vibrating feeder with a self-locking function, characterized in that it includes a lower hopper and a supporting cone arranged on the top of the lower hopper, the arch-breaking cone is arranged at the center position of the inner side of the lower hopper through a supporting beam fixed on the wall of the conical hole of the lower hopper, the top of the arch-breaking cone is placed in the supporting cone, and a plurality of groups of spiral partitions for realizing the self-locking function of the vibrating feeder are arranged on the inner wall of the conical hole of the lower hopper, the inner edge of the spiral partition is fixedly connected to the arch-breaking cone and the middle part of the spiral partition is fixed on the supporting beam, and two vibration motors with adjustable inclination angles are arranged on the supporting beam outside the lower hopper, and the two vibration motors are symmetrically cross-arranged at 180° and operate in opposite directions to each other to form vortex-type vibration.

[0008] Furthermore, 3-12 groups of spiral partitions are evenly welded on the inner wall of the conical hole of the discharge hopper to form 3-12 spiral channels for material discharge, the inner edge of the spiral partition is welded and fixed to the arch-breaking cone, and the middle part of the spiral partition is welded and fixed to the support beam.

[0009] Furthermore, the spiral angle of the spiral partition is 20° to 540°.

[0010] Furthermore, the downward inclination angle of the inner side of the spiral partition is 0° to 35°.

[0011] Furthermore, the axes of the two vibration motors intersect with each other to form an angle of 0° to 90°, and the distance between the two vibration motors and the center of gravity of the equipment is adjustable to obtain different torques. The two vibration motors are fixed on a support beam with adjustable upper and lower positions to obtain the maximum exciting force close to the material arch breaking position.

[0012] Furthermore, the axes of the supporting cone and the arch-breaking cone form an angle of 10° to 85° with the horizontal plane, and the directions of the angles are consistent. The supporting cone and the arch-breaking cone participate in arch breaking at the same time, wherein the arch-breaking cone is used for central arch breaking and the supporting cone is used for breaking the root of the arch.

[0013] Furthermore, a plurality of spring supports are evenly distributed along the circumferential direction on the outer bottom of the support cone, and the support cone is fixed to the support body via a buffer spring matched with the spring supports.

[0014] Furthermore, an annular sealing baffle and a soft seal for sealing the support cone and the support body are provided at the bottom of the outer edge of the support cone.

[0015] The present invention obtains different arch breaking capabilities by adjusting the angle between two vibration motors; obtains different torques by adjusting the center distance between the two vibration motors, thereby increasing the vortex area in the vertical direction of the arch breaking cone; and makes the force of the vortex vibration closer to the arch position of the material by adjusting the position of the middle support beam between the two vibration motors, so as to achieve a better arch breaking effect. Through the coordinated use of the above three methods, the arch breaking cone and the support cone participate in the arch breaking at the same time, so that the material is quickly stratified to form friction between the material and the material, reduce the wear of the part in contact with the material in the machine body, and extend the service life of the equipment; speed up the falling speed of the material, so that the large piece of material accelerates the flushing of the small piece of material layer, and effectively avoids the occurrence of material hanging on the wall and material storage.

[0016] Compared with the prior art, the present invention has the advantages of multi-point arch breaking, eradication of arch knots and wall hanging caused by arch knots, high arch breaking efficiency, less machine body wear and uninterrupted material transportation; the vortex arch breaking feeder has a self-locking function, that is, the feeder automatically stops dropping materials after the vibration motor stops running, effectively avoiding the defect of achieving vibration feeder dropping control by installing a gate at the dropping end of the lower hopper, and has a good prospect for promotion and application.
