Description

Technical Field

[0001] This utility model belongs to the technical field of auger conveyor devices, and more specifically, it relates to an auger conveyor device with a double plow-blade arch-breaking structure. Background Technology

[0002] Screw conveyors, more commonly known as screw conveyors in engineering and industrial fields, are continuous conveying equipment that uses rotating helical blades (i.e., "augers") to push materials, thereby achieving horizontal, inclined, or vertical material transport.

[0003] Based on existing technology, it has been found that existing auger conveying devices only achieve lateral conveying and arch breaking / flow assistance through the auger during use. However, this method is prone to "bridging" or "rat hole" phenomena, causing the material above the hopper to be suspended and stuck, unable to fall smoothly, interrupting the feeding. When the arch bridge suddenly collapses, a large amount of material will rush to the auger instantly, resulting in a surge in the feeding volume in a short period of time, uneven feeding, unstable flow, resulting in a large load on the auger, high energy consumption, and rapid wear. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an auger conveyor with a double plow-blade arch-breaking structure. This solves the problem that existing auger conveyors only achieve lateral conveying and arch-breaking flow assistance through the auger, which is prone to "bridging" or "rat hole" phenomena. This causes the material above the hopper to be suspended and stuck, resulting in uneven feeding, unstable flow, high auger load, high energy consumption, and rapid wear.

[0005] This utility model discloses a screw conveyor device with a double plowshare arch-breaking structure, achieved through the following specific technical means: A screw conveyor with a double plow-blade arch-breaking structure includes a feeding mechanism, a rotating mechanism, an arch-breaking mechanism, and a conveying mechanism. The feeding mechanism is equipped with a rotating mechanism inside; the arch-breaking mechanism is located at the bottom of the feeding mechanism and is situated at the bottom of the rotating mechanism; the conveying mechanism is located at the bottom of the feeding mechanism. The feeding mechanism includes: a main body, which is a hopper body; The rotating mechanism includes: a motor A, which is fixedly mounted on the side of the main body; the motor A is connected to a rotating component; and a plow blade A is mounted on the rotating component. The conveying mechanism includes: a conveying component, which is fixedly installed at the bottom of the main body; a motor C is fixedly installed on the conveying component; and the output shaft of the motor C is connected to the auger.

[0006] Furthermore, the feeding mechanism also includes a feeding port and a discharging port; The feeding port is located at the top of the main body; the discharge port is located at the bottom of the main body.

[0007] Furthermore, the rotating component is located at the top of the interior of the main body; the plow blade A is configured with a V-shaped structure; and the plow blade A is evenly distributed on the rotating component.

[0008] Furthermore, the arch-breaking mechanism includes: a motor B and a drive roller; The motor B is fixedly mounted on the side of the main body; the drive roller is connected to the output shaft of the motor B; the drive roller is located at the bottom inside the main body.

[0009] Furthermore, the arch-breaking mechanism also includes: a plow blade B; The plow blade B is fixedly mounted on the drive roller; the plow blade B is offset from the plow blade A.

[0010] Furthermore, the inlet and outlet at the top of the conveyor are correspondingly arranged; the diameter at the outlet of the conveyor is smaller than the diameter at the inlet; the auger is configured as a spiral structure; and the auger is located inside the conveyor.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, plow blade A and plow blade B are provided. Plow blade A is mounted on the rotating component, while plow blade B is mounted on the drive roller. During operation, motor A drives the rotating component and plow blade A to rotate, while motor B drives the drive roller and plow blade B to rotate. Plow blade A, positioned at the top of the main body, first contacts any loose arched structures or "rat holes" that may form on the upper part of the main body. Its function is to "pioneer break arches" and "loosen" the structure, breaking up large, initial arched pieces to prepare the material for entering the more easily arched conical area. Under its own weight and the action of plow blade A, the material converges. The material is collected at the main cone section, and the plow blade B, through rotation, can break up the arches in this area. The plow blades A and B are arranged vertically and horizontally. At the intersection of their movement trajectories, the material flows from different directions will penetrate, fold, and stretch each other, generating strong shearing forces and improving the arch breaking effect. This minimizes the possibility of arching along the entire path, achieving arch breaking coverage without dead angles. It eliminates the impact load on the auger caused by the sudden collapse of the arch, making the auger's load very stable, significantly reducing energy consumption, reducing wear, and providing extremely high and stable conveying efficiency. It is also more adaptable to conveying different materials. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides an auger conveyor with a double plow-blade arch-breaking structure, including a feeding mechanism 1, a rotating mechanism 2, an arch-breaking mechanism 3, and a conveying mechanism 4; The feeding mechanism 1 is equipped with a rotating mechanism 2; the arch-breaking mechanism 3 is located at the bottom of the feeding mechanism 1 and is located at the bottom of the rotating mechanism 2; the conveying mechanism 4 is located at the bottom of the feeding mechanism 1. The feeding mechanism 1 includes: a main body 101, which is the hopper body; The rotating mechanism 2 includes: a motor A201, which is fixedly installed on the side of the main body 101; the motor A201 is connected to the rotating component 202; a plow blade A203 is installed on the rotating component 202; the motor A201 is used to drive the rotating component 202 to rotate, and the plow blade A203 is installed inside the top of the main body 101. It first contacts the loose arched structure or "mouse hole" that may be formed on the upper part of the main body 101. Its function is to "break the arch" and "loosen" the large, initial arched structure, and prepare the material to enter the cone area that is more prone to arching. Through the disturbance of the plow blade A203, the material in the entire cross section of the main body 101 moves downward, forming a more ideal "overall flow" or "plunger flow". All materials can be discharged in sequence, avoiding the long-term retention and deterioration of old materials. The conveying mechanism 4 includes: a conveying component 401, which is fixedly installed at the bottom of the main body 101; a motor C402 is fixedly installed on the conveying component 401; the output shaft of the motor C402 is connected to the auger 403; the conveying component 401 is used to drive the auger 403 to rotate through the motor C to realize the conveying of materials.

[0019] Among them, such as Figure 1 As shown, the feeding mechanism 1 also includes a feeding port 102 and a discharging port 103; the feeding port 102 is located at the top of the main body 101; and the discharging port 103 is located at the bottom of the main body 101.

[0020] Among them, such as Figure 2 As shown, the rotating component 202 is located at the top inside the main body 101; the plow blade A203 is configured as a V-shaped structure; the plow blade A203 is evenly distributed on the rotating component 202.

[0021] Among them, such as Figure 3 As shown, the arch-breaking mechanism 3 includes: a motor B301 and a drive roller 302; the motor B301 is fixedly installed on the side of the main body 101; the drive roller 302 is connected to the output shaft of the motor B301; the drive roller 302 is installed at the bottom inside the main body 101.

[0022] Among them, such as Figure 3 As shown, the arch-breaking mechanism 3 also includes: a plow blade B303; the plow blade B303 is fixedly mounted on the drive roller 302; the plow blade B303 is offset from the plow blade A203; through the arrangement of the plow blades A203 and B303, their rotation trajectories can cover almost the entire cross-section of the cone portion of the main body 101, and the plow blades A203 and B303 are arranged vertically and horizontally. In the intersection area of ​​the movement trajectories, the material flow in different directions will penetrate, fold, and stretch each other, generating strong shearing force, improving the arch-bridge breaking effect. They can not only destroy the central arch bridge, but also effectively clean up... The material near the inner wall of the main body 101 eliminates the dead angle of arch breaking, realizes full-section arch breaking, is more efficient, has a more balanced arch breaking force, and avoids flow deviation. The motor A201 drives the plow blade A203 and the motor B301 and plow blade B303 to rotate in opposite directions. The forces generated by the plow blades A203 and B303 cancel each other out in the horizontal direction, mainly generating a downward vertical tearing force on the material. This makes the material fall evenly and vertically, with a more ideal flow pattern, without generating vortices or flow deviation, more stable power, and stronger reliability, and can be applied to the processing of different materials.

[0023] Among them, such as Figure 3As shown, the feed inlet and discharge outlet 103 at the top of the conveyor 401 are correspondingly arranged; the diameter of the outlet of the conveyor 401 is smaller than the diameter of the feed inlet; the auger 403 is set as a spiral structure; the auger 403 is set inside the conveyor 401; the arrangement of the conveyor 401 and the auger 403 can prevent material blockage, improve reliability, and achieve uniform and stable feeding and discharging. The motors A201, B301 and C402 are all controlled by the background control panel, which is a conventional technical means.

[0024] The specific usage and function of this embodiment are as follows: In this invention, when using this device, material is fed into the main body 101 through the feeding port 102. The rotating component 202 and the plow blade A203 are rotated by the motor A201. By contacting the loose arched structure or "rat hole" that may form on the upper part of the main body 101, the device "breaks the arch" and "loosens" the large, initial arched structure, preparing the material to enter the cone area where it is more prone to arching. The motor B301 drives the drive roller 302 and the plow blade B303 to break the arch of the material at the bottom of the main body 101. The motors A201 and B301 rotate in opposite directions, so that the forces generated by the plow blades A203 and B303 cancel each other out in the horizontal direction, mainly generating a downward vertical tearing force on the material. This makes the material fall evenly and vertically, and then enter the conveyor 401 through the discharge port 103. The auger 403 is driven to rotate by the motor B402 to realize the conveying of the material.
