Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, specifically relating to an anti-bridging feeding machine. Background Technology

[0002] Anti-bridging feeders are specially designed to solve the problem of material bridging during storage and transportation. Bridging refers to the formation of an arched structure in a silo or container due to the material's stickiness, clumping, or poor flowability, preventing it from being discharged smoothly. Anti-bridging feeders effectively break up material clumps and prevent bridging by incorporating a mixer, buffer plate, or a specially designed silo structure inside the equipment, thus ensuring continuous and stable material transportation.

[0003] In some existing anti-bridging feeding machines, the receiving position of the hopper is usually relatively fixed when receiving materials discharged from the front-end equipment. This design causes the material to fall in a concentrated manner, forming local stacking. This concentrated falling and stacking method not only fails to effectively disperse the material, but also makes it easier to form new material arches or compacted blocks in the landing area. This has an extremely adverse effect on the working efficiency of the subsequent dispersing mechanism, reducing the overall anti-bridging and feeding smoothness effect. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide an anti-bridging feeding machine. This addresses the issue mentioned in the background section where existing anti-bridging feeding machines typically have a fixed receiving position for the hopper when receiving materials discharged from the front-end equipment. This design leads to concentrated material drop points and localized stacking. This concentrated material drop and stacking not only fails to effectively disperse the material but also makes it easier to form new material arches or compacted blocks in the drop area. This has a severely adverse impact on the efficiency of the subsequent dispersing mechanism, reducing the overall anti-bridging and feeding smoothness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-bridging feeding machine, comprising a main body and a scattering mechanism disposed on top of the main body to scatter falling materials, thereby reducing the accumulation of materials due to excessive concentration of falling points. The scattering mechanism includes a sealing plate engaged with the top of the hopper, inner plates symmetrically arranged on the inner side of the sealing plate, a flow guide fixedly connected to one side of the sealing plate, a third motor fixedly connected to the top side of the sealing plate, a drive gear fixedly connected to the output end of the third motor, a synchronous belt drivingly connected to the outer side of the drive gear, a driven gear drivingly connected to the inner side of the synchronous belt, a rotating shaft fixedly connected to the inner side of the driven gear, a sealing plate rotatably connected to the outer side of the top end of the rotating shaft, a fixed base rotatably connected to the outer side of the bottom end of the rotating shaft, side arms symmetrically arranged on the outer side of the fixed base, hoppers fixedly connected to both ends of the side arms, and several impact plates symmetrically arranged on the outer side of the rotating shaft.

[0006] Preferably, the main body mechanism includes a frame, a feeding pipe is fixedly connected to the top of the frame, a discharge pipe is fixedly connected to one side of the bottom of the feeding pipe, a conveying blade is rotatably connected to the inner side of the feeding pipe, a first motor is fixedly connected to one end of the conveying blade, a feeding pipe is fixedly connected to one side of the first motor, a hopper is fixedly connected to the top of the feeding pipe, a second motor is fixedly connected to one side of the hopper, and a plurality of stirring blades are symmetrically arranged on the outer side of the output end of the second motor.

[0007] Preferably, the bottom of the sealing plate is threaded with a positioning screw, and several positioning screws are symmetrically arranged. A foot pad is threaded to the outside of the positioning screw, and a cover is fixedly connected to one side of the foot pad. The cover is located outside the synchronous belt.

[0008] Preferably, a tensioning wheel is rotatably connected to one side of the top of the shield, and two tensioning wheels are symmetrically arranged. A synchronous belt is driven to one side of each tensioning wheel.

[0009] Preferably, a washer is movably connected to the outer side of one end of the positioning screw, and the washer is located on one side of the foot pad.

[0010] Preferably, the inner panel is made of transparent acrylic material, and a sealing plate is fixedly connected to the outer side of the inner panel.

[0011] Preferably, both the hopper and the flow guide are truncated frustum structures with a top diameter smaller than the bottom diameter.

[0013] Compared with the prior art, this utility model provides an anti-bridging feeding machine, which has the following beneficial effects:

[0014] 1. This utility model incorporates impact plates, with the device installed below the front-end discharge mechanism. A guide shroud receives the material discharged from the front-end device. A third motor drives the drive gear to rotate, which in turn drives the driven gear to rotate at a constant speed via a synchronous belt. The driven gear then drives the rotating shaft to rotate inside the sealing plate and fixed base. As the material falls onto the inner wall of the hopper, some material is struck by the rotating impact plates, causing it to disperse. This portion of material loses kinetic energy upon impacting the inner wall of the hopper and falls into a portion of the stirring blades. The remaining material is indirectly arranged... The material falls naturally through the gaps between the impact plates and is discharged to another part of the mixing blade area. At the same time, the second motor is turned on to drive the mixing blade to rotate in the hopper, breaking up the stacked material. The processed material falls to the top of the conveying blade in the feeding pipe. The first motor is turned on to drive the conveying blade to rotate in the feeding pipe, conveying the material to the discharge pipe and then to the back-end equipment or collection container. This can effectively scatter and disperse the falling material, reduce the concentration of its landing point, and reduce the occurrence of new material arches or compacted blocks in the landing area, thereby improving the operating efficiency of the device.

[0015] 2. By setting up a shield, this utility model can effectively shield the transmission area of ​​the device, reducing the occurrence of material splashing into the working area of ​​the driving gear and driven gear, which could lead to impact or wear.

[0016] 3. By setting a gasket, this utility model can effectively reduce the loosening of the positioning screw during long-term use and ensure the positioning screw's limiting ability.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description
