Description

Technical Field

[0001] This utility model relates to the field of chain conveyor feeding technology, and in particular to an automatic material clearing device for chain conveyors. Background Technology

[0002] A chain conveyor is a transmission device that uses standard chain plates as the bearing surface and a motor and reducer as the power transmission.

[0003] However, in existing technologies, bentonite has a certain degree of viscosity, and when it accumulates on the chain plate surface, it increases the weight of the chain plate. This causes the drive motor, chain, sprocket and other components to bear a greater load. Long-term operation may cause the motor to overload, accelerate the wear of the chain and sprocket, and shorten the service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that bentonite has a certain degree of viscosity, and its accumulation on the chain plate surface will increase the weight of the chain plate, so an automatic material clearing device for chain plate machines is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic material clearing device for a chain conveyor, comprising a chain conveyor body, a drive shaft installed on the inner side of one end of the chain conveyor body, a transmission assembly connected to one end of the drive shaft, and a cleaning mechanism connected to one end of the transmission assembly.

[0006] The cleaning mechanism includes a rotating cylinder, a rotating rod inside the rotating cylinder, multiple rotating sleeves movably sleeved on the outer surface of the rotating rod, multiple limiting holes on the outer surface of the rotating cylinder, a scraper slidably connected inside the limiting holes, one end of the scraper being fixedly connected to the outer side of the rotating sleeve, one end of the scraper extending out of the inner side of the rotating cylinder, and a fixed shaft being fixedly connected to one end of the rotating rod.

[0007] Preferably, a second support frame is rotatably connected to the outer surface of one end of the fixed shaft.

[0008] Preferably, the transmission assembly includes a central shaft, a driven gear is fixedly connected to the outer surface of one end of the central shaft, and one end of the central shaft is fixedly connected to the side wall of the rotating cylinder.

[0009] Preferably, a driving gear is meshed below the driven gear.

[0010] Preferably, the drive gear is fixedly connected to the outer surface of one end of the drive shaft.

[0011] Preferably, a first support frame is rotatably connected to the outer surface of one end of the central shaft.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the central shaft drives the rotating cylinder to rotate in linkage, thereby driving multiple scrapers connected to it to rotate synchronously. During the rotation, the scrapers can effectively clean the surface of the chain conveyor body, prevent materials from adhering and accumulating at the discharge port, improve the stability of equipment operation and the continuity of material discharge. The scrapers can also rotate locally around their own rotating rod. Because the rotating rod and the axis of the rotating cylinder do not coincide, an eccentric structure is formed, which causes the scrapers to generate periodic offset force during rotation and slide radially on the inner wall of the limiting hole, thus having an automatic extension and retraction function. When the scraper moves away from the chain conveyor, it automatically retracts to avoid interference, and when it moves close, it automatically unfolds to contact the chain plate, and achieves material scraping and surface cleaning through rotational kinetic energy.

[0014] 2. In this utility model, the drive shaft drives the drive gear to rotate. After the drive gear meshes with the driven gear, it transmits power stably to the driven gear, thereby driving the central shaft to rotate. The central shaft, as the main power shaft, directly determines the operation of the subsequent devices. The rotating central shaft further drives the rotating cylinder to rotate synchronously. The rotating cylinder is installed through low-friction structures such as bearings to ensure smooth rotation and low energy consumption. Under the stable support of the first support frame, the rotating cylinder maintains the set trajectory to rotate, avoiding shaking and improving the reliability of system operation. The scraper installed on the rotating cylinder generates force by rotation, so as to make contact with the cleaning surface and complete the scraping operation. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1-4 As shown, this utility model provides an automatic material clearing device for a chain conveyor, including a chain conveyor body 1, a drive shaft 2 installed on the inner side of one end of the chain conveyor body 1, a transmission assembly 3 connected to one end of the drive shaft 2, and a cleaning mechanism 4 connected to one end of the transmission assembly 3.

[0023] The cleaning mechanism 4 includes a rotating cylinder 41, a rotating rod 46 disposed inside the rotating cylinder 41, and multiple rotating sleeves 45 movably sleeved on the outer surface of the rotating rod 46. Multiple limiting holes 42 are provided on the outer surface of the rotating cylinder 41, and scrapers 43 are slidably connected inside the limiting holes 42. One end of the scraper 43 is fixedly connected to the outer side of the rotating sleeve 45, and the other end of the scraper 43 extends out of the inner side of the rotating cylinder 41. A fixed shaft 44 is fixedly connected to one end of the rotating rod 46. A second support frame 48 is rotatably connected to the outer surface of one end of the fixed shaft 44.

[0024] The specific settings and functions of this embodiment are described below. During the operation of this device, the rotating cylinder 41 rotates synchronously with the central shaft 33. As the central shaft 33 rotates, the rotating cylinder 41 also rotates around its axis. Since there is a transmission connection between the scraper 43 and the rotating cylinder 41, the rotating cylinder 41 applies a driving force to the scraper 43 when it rotates, thereby achieving synchronous rotation of multiple scrapers 43. Through this structural design, the scraper 43 can effectively clean the surface of the chain conveyor body 1, preventing material from adhering and accumulating near the discharge port and causing blockages, thus improving the stability of equipment operation and the continuity of material discharge.

[0025] Furthermore, as the scraper 43 rotates with the rotating cylinder 41, each scraper 43 also rotates locally around its own rotating rod 46. It is important to note that the rotation center of the rotating rod 46 does not coincide with the rotation center of the rotating cylinder 41; that is, they are located on different spatial axes, forming a typical eccentric structure. This eccentric design causes a periodic offset force to be generated on the scraper 43 when the rotating cylinder 41 rotates, thereby causing the scraper 43 to slide radially along the inner wall of the limiting hole 42.

[0026] This sliding process endows the scraper 43 with a retractable motion capability, meaning it can automatically extend or retract inward or outward according to the rotation angle during rotation. When the scraper 43 moves away from the chain conveyor body 1, its automatic retraction effectively avoids interference or collision with surrounding structural components, improving the adaptability and safety of the structure. When the scraper 43 approaches the chain conveyor body 1, it unfolds and makes full contact with the chain plate surface. With the help of the rotational kinetic energy provided by the rotating cylinder 41, it scrapes off the material adhering to or deposited on the surface of the equipment, thereby achieving a highly efficient cleaning function.

[0027] Example 2: Figure 1 and Figure 2 As shown, the transmission assembly 3 includes a central shaft 33. A driven gear 32 is fixedly connected to the outer surface of one end of the central shaft 33, and one end of the central shaft 33 is fixedly connected to the side wall of the rotating cylinder 41. A driving gear 31 is meshed below the driven gear 32. The driving gear 31 is fixedly connected to the outer surface of one end of the driving shaft 2. A first support frame 47 is rotatably connected to the outer surface of one end of the central shaft 33.

[0028] The overall effect of this embodiment is that when the drive shaft 2 starts to rotate, its rotational motion will directly drive the drive gear 31 mounted on it to rotate synchronously. Since the drive gear 31 and the driven gear 32 mesh with each other, the rotation of the drive gear 31 will efficiently and stably transmit power to the driven gear 32 through the gear transmission mechanism, thereby driving it to perform corresponding rotational motion.

[0029] As the driven gear 32 rotates, the central shaft 33, coaxially connected to it, also begins to rotate. This central shaft 33 serves as the main power transmission shaft for the entire system, and its rotation directly affects the operation of subsequent components. During rotation, the central shaft 33 further drives the rotating cylinder 41 connected to it to rotate synchronously. The rotating cylinder 41 is typically mounted on a fixed structure via bearings or other low-friction connections, thus exhibiting good mechanical stability and minimal energy loss during rotation.

[0030] Under the structural support and constraint of the first support frame 47, the rotation of the rotating cylinder 41 can be maintained within a predetermined track or angle range, effectively preventing swaying or deviation and ensuring the operational reliability of the entire system. At this time, the scraper 43 installed on the outer wall or end of the rotating cylinder 41 will receive a substantial force driven by the rotation, causing it to perform contact scraping operations along the inside of the equipment or the target cleaning surface. Through this mechanical drive, the scraper 43 can continuously and uniformly complete the cleaning of surface impurities, deposits, or liquid residues, achieving a highly efficient cleaning effect.

[0031] The operating principle and usage of this device are as follows: When the rotating cylinder 41 rotates together with the central shaft 33, it applies force to the scraper 43, thereby driving the multi-layer scraper 43 to rotate synchronously. At this time, the scraper 43 cleans the surface of the chain conveyor body 1, preventing material accumulation at the discharge point. Furthermore, when the scraper 43 rotates under the drive of the rotating cylinder 41, it also rotates around the rotating rod 46. Since the rotation centers of the rotating rod 46 and the rotating cylinder 41 are not on the same horizontal line, forming an eccentric structure, the scraper 43 slides inside the limiting hole 42 when the rotating cylinder 41 rotates, thus retracting during rotation. The retraction of the scraper 43 not only prevents it from contacting other objects when it moves away from the chain conveyor body 1, but also scrapes away accumulated material on the surface with the help of the rotating cylinder 41.

[0032] When the drive shaft 2 rotates, it drives the drive gear 31 to rotate. At this time, the drive gear 31 transmits the force to the driven gear 32, causing the central shaft 33 to start rotating. When the central shaft 33 rotates, it drives the rotating cylinder 41 to rotate synchronously. The rotating cylinder 41 rotates under the support of the first support frame 47, which in turn causes the scraper 43 to be subjected to force and begin the cleaning operation.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
