Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment, specifically to an anti-clogging screw conveyor for a feeder. Background Technology

[0002] As a key piece of equipment for continuous material conveying in industrial production, the screw feeder is characterized by its compact structure, stable conveying, and wide applicability to various material types. Its core working principle is to drive the screw conveyor rod to rotate through the drive device, and use the spiral blades on the surface of the rod to push the material to move along the axial direction of the hopper, ultimately realizing the directional conveying of the material from the inlet to the outlet. It is an important link connecting raw material storage, processing and subsequent processes.

[0003] Traditional screw conveyors rely solely on the thrust of a single screw blade to transport materials. The blade direction is fixed and there are no auxiliary dispersing components, making it difficult to break the stable accumulation state of materials caused by gravity or viscosity. Especially in areas such as hopper corners and discharge ports, materials are prone to stagnation due to uneven thrust distribution. For materials containing a small amount of lumps or hard impurities, the single screw structure cannot break them or avoid them, leading to material blockage.

[0004] Therefore, it is necessary to invent an anti-clogging screw conveyor for a feeder to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a clogging-resistant screw conveyor for a feeder. By setting up a cooperative structure of anti-clogging components and transmission components, two sets of rotating rods are set on the inner wall of the hopper. Multiple sets of mounting shells are fixed on the outer side of the rotating rods through connecting sleeves. Multiple sets of arc-shaped baffles in a ring array are inclinedly set on the outer side of adjacent mounting shells. The rotation of the rotating rods drives the baffles to continuously agitate and divert the material. This solves the problem in the existing technology of traditional screw conveyors, which have limited thrust from a single screw blade and lack of auxiliary dispersing components, resulting in material easily accumulating at the corners of the hopper and the discharge port, and cannot handle the clogging caused by lumps or hard impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging screw conveyor for a feeder, comprising...

[0007] A hopper is used to support the overall device. A drive motor is fixedly connected to the right side of the hopper. A conveying rod with helical blades on its surface is rotatably connected to the inner wall of the hopper. The conveying rod is connected to the drive motor. A transmission assembly is provided on the outer side of the conveying rod.

[0008] An anti-clogging component is installed on the inner wall of the hopper. The anti-clogging component includes two sets of rotating rods. The rotating rods are rotatably connected to the inner wall of the hopper. An installation shell is fixedly installed on the outer side of the rotating rod through a connecting sleeve. Multiple sets of installation shells are provided. A baffle is inclinedly arranged on the outer side of two adjacent sets of installation shells. The connecting sleeve is fixedly installed on the outer side of the rotating rod through fastening bolts.

[0009] Preferably, a positioning post is fixedly connected to the side of the mounting shell near the rotating rod, and a slot is provided on the outer side of the rotating rod to engage with the positioning post.

[0010] Preferably, the spoiler is arc-shaped, and multiple sets of spoilers are provided, with multiple sets of spoilers arranged in a ring array on the outside of two adjacent sets of mounting shells.

[0011] Preferably, the transmission assembly includes a transmission wheel a, a belt, and a transmission wheel b. The transmission wheel a is fixedly connected to the right side of the rotating rod, and the transmission wheel b is fixedly connected to the outside of the conveying rod. The transmission wheel a and the transmission wheel b are connected by a belt drive.

[0012] Preferably, there are two sets of each of the transmission wheel a, belt and transmission wheel b. The two sets of transmission wheels a, belt and transmission wheel b are respectively arranged on the outside of the two sets of rotating rods and conveying rods, and the two sets of transmission wheels a, belt and transmission wheel b are staggered.

[0013] Preferably, the connecting sleeve is inserted into the outer side of two adjacent sets of mounting shells, and the fastening bolt passes through the mounting shell.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This utility model features a ring array of multiple arc-shaped baffles on the outside of the mounting shell, with the baffles on adjacent mounting shells arranged at an angle. When the rotating rod drives the mounting shell to rotate, the baffles can continuously agitate and divert the material in the hopper, breaking up the "bridging" and "clumping" formed by the material due to gravity or viscosity. This is especially effective for powdery, high-humidity, and other easily agglomerated materials, significantly reducing the risk of accumulation and blockage. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1 - Figure 3 The illustrated anti-clogging screw conveyor includes a hopper 1 and an anti-clogging component 5.

[0025] The hopper 1 is used to support the entire device and serves as the foundation for the device. It is used to hold the material to be conveyed and provides installation space and operating environment for the conveying rod 2 and the anti-blocking component 5. The left side is set as the discharge port. The right side of the hopper 1 is fixedly connected to the drive motor 3, which is a geared motor. It drives the conveying rod 2 to rotate, thereby driving the entire conveying system and the anti-blocking component 5. Its output power and speed can be adjusted according to the material characteristics. The inner wall of the hopper 1 is rotatably connected to the conveying rod 2, which has helical blades on its surface. The material is pushed from the right side of the hopper 1 to the discharge port on the left side by the thrust of the helical surface. At the same time, the transmission wheel b43 on the outer side of the conveying rod 2 rotates synchronously with it, providing a power source for the anti-blocking component 5. The conveying rod 2 is connected to the drive motor 3. The outer side of the conveying rod 2 is equipped with a transmission component 4.

[0026] The anti-clogging component 5 is installed on the inner wall of the hopper 1. The anti-clogging component 5 includes two sets of rotating rods 51. The rotating rods 51 are rotatably connected to the inner wall of the hopper 1 and rotate under the drive of the transmission wheel a41. Their axis is parallel to the conveying rod 2. The outer mounting shell 52 drives the baffles 53 to rotate synchronously. The mounting shell 52 is fixedly installed on the outer side of the rotating rod 51 through the connecting sleeve 54 to fix the baffles 53. There are multiple sets of mounting shells 52. The baffles 53 are inclinedly arranged on the outer side of the two adjacent sets of mounting shells 52. The arc-shaped surface of the baffles 53 reduces the rigid collision with the material and reduces the risk of material breakage. At the same time, the curved surface guides the material to diffuse radially and breaks the "bridging" and "clumping" formed by the material due to gravity or viscosity. The connecting sleeve 54 is fixedly installed on the outer side of the rotating rod 51 by the fastening bolt 57. The locking of the mounting shell 52 can be quickly released by rotating the fastening bolt 57, which is convenient for disassembly and maintenance.

[0027] like Figure 1 - Figure 3 As shown, a positioning post 55 is fixedly connected to the side of the mounting shell 52 near the rotating rod 51. A slot 56 is provided on the outer side of the rotating rod 51 to engage with the positioning post 55. By engaging the positioning post 55 with the slot 56, the mounting shell 52 can be quickly aligned and assembled during installation, while also increasing the stability between the mounting shell 52 and the rotating rod 51. The spoiler 53 is arc-shaped, and multiple sets of spoilers 53 are arranged in a ring array on the outer side of two adjacent sets of mounting shells 52.

[0028] like Figure 1 and Figure 4 As shown, the transmission assembly 4 includes a transmission wheel a41, a belt 42, and a transmission wheel b43. Transmission wheel a41 is fixedly connected to the right side of the rotating rod 51 and rotates under the drive of the belt 42, thereby driving the rotating rod 51 to rotate around its own axis. Transmission wheel b43 is fixedly connected to the outside of the conveying rod 2 and rotates synchronously with the conveying rod 2. It drives the belt 42 to move through friction. Transmission wheel a41 and transmission wheel b43 are connected by the belt 42, and the rotational motion of transmission wheel b43 is transmitted to transmission wheel a41 by the friction between transmission wheel a41 and transmission wheel b43. Two sets of transmission wheels a41, belt 42, and transmission wheel b43 are provided, and the two sets are respectively located on the outside of the two sets of rotating rods 51 and conveying rods 2, with the two sets of transmission wheels a41, belt 42, and transmission wheel b43 arranged alternately. Connecting sleeves 54 are inserted into the outside of two adjacent sets of mounting shells 52, and fastening bolts 57 penetrate the mounting shells 52.

[0029] The working principle of this device is as follows: When the device is started, the drive motor 3 outputs power to drive the conveyor rod 2 to rotate. The spiral blades on the surface of the conveyor rod 2 rotate accordingly. Through the thrust of the spiral surface, the material in the hopper 1 is stably pushed from the right side to the left side of the discharge port, thus realizing the basic material conveying function.

[0030] At the same time, the transmission wheel b43 on the outer side of the conveyor rod 2 rotates synchronously with it, and transmits power to the transmission wheel a41 on the right side of the rotating rod 51 through the belt 42, thereby driving the two sets of rotating rods 51 to rotate synchronously on the inner wall of the hopper 1.

[0031] When the rotating rod 51 rotates, the multiple sets of mounting shells 52, which are fixed to the outside by the connecting sleeve 54 and the fastening bolts 57, rotate accordingly, and the arc-shaped baffles 53 on the outside of the mounting shells 52 move synchronously. During the rotation, the multiple sets of ring-shaped baffles 53, which are arranged at an angle, continuously agitate and divert the material in the hopper 1. The arc-shaped surface reduces rigid collisions with the material, preventing material breakage, while the tilt angle guides the material to diffuse radially, breaking up bridging and agglomeration caused by gravity or viscosity.

[0032] When maintenance is required, the fastening bolts 57 are loosened to release the fixing constraint of the connecting sleeve 54 on the mounting shell 52. At this time, the connecting sleeve 54 can be pulled out from the outside of the two adjacent sets of mounting shells 52, so that the positioning post 55 on one side of the mounting shell 52 can be disengaged from the slot 56 outside the rotating rod 51, which facilitates the replacement of the worn spoiler 53 or the cleaning and maintenance of the mounting shell 52.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
