Description

Technical Field

[0001] This utility model relates to the field of transportation machinery, and in particular to a sweeping return material return device. Background Technology

[0002] The transportation machinery sector primarily involves various equipment and systems used for material handling, transportation, and conveying, including belt conveyors, elevators, stacker-reclaimers, and other similar equipment. These machines are widely used in industries such as mining, metallurgy, construction, and logistics for the efficient transport of bulk materials. A cleaning return device is a piece of equipment used in conveyor systems, typically to clean residual material from the conveyor belt, preventing material accumulation and ensuring the normal operation of the transportation equipment. These devices improve system efficiency by cleaning residual material from the return belt. The connection between the transportation machinery sector and cleaning return devices lies in the fact that cleaning return devices are crucial components in transportation machinery, ensuring the smooth operation of the conveying system and preventing material waste and equipment failure.

[0003] The working principle of a sweeping return material return device is to remove residual material from the conveyor belt using physical or mechanical means by sweeping devices installed on the return section of the conveyor belt. These devices typically include tools such as scrapers, brushes, or blades, which operate along the return section of the conveyor belt to remove adhering residual material. The design of the sweeping device takes into account factors such as the type of material, the speed of the conveyor belt, and the operating environment to ensure that the sweeping effect does not affect the normal operation of the conveyor belt. The sweeping return material return device can effectively reduce material waste, reduce conveyor belt wear, and ensure the efficient operation of the conveying system.

[0004] In the belt conveyor industry, material accumulation on belts is a common problem. During belt transportation, transported materials, as well as dust and debris, can adhere to the belt, severely hindering normal equipment operation and reducing production efficiency. This is especially true in complex environments such as mines, where accumulated material is often large, difficult to remove, and cannot be promptly transported away, leading to buildup and environmental pollution. Therefore, a cleaning and return material handling device is proposed to address these issues. Utility Model Content

[0025] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a cleaning return material return device, including a cleaning box shell 1. The cleaning box shell 1 is the main external structure of the cleaning return material return device, mainly used to accommodate various internal cleaning and conveying mechanisms. Two frames 3 are fixedly connected to the top of the cleaning box shell 1. The frames 3 play the role of support and fixing devices in the cleaning return material return device. A gathering block 7 is fixedly connected to the bottom of the cleaning box shell 1. The gathering block 7 is located at the bottom of the cleaning box shell 1 and plays the role of gathering materials and guiding them into the waste material return device. The function of the conveying mechanism 4 is that the belt cleaning mechanism 5 is fixedly connected inside the cleaning box shell 1. The belt cleaning mechanism 5 is one of the core components of the cleaning return and return device, and is mainly used to clean the residual materials on the conveyor belt. The bottom of the gathering block 7 is equipped with the waste conveying mechanism 4. The waste conveying mechanism 4 is responsible for conveying the waste or residual materials cleaned by the belt cleaning mechanism 5 from the bottom of the cleaning box shell 1 to the processing area. The gathering block 7 adopts a square funnel-shaped design, and the bottom of the gathering block 7 corresponds to the top of the waste conveying mechanism 4.

[0026] The belt cleaning mechanism 5 includes multiple mounting seats 51, which are fixedly connected to the outside of the cleaning box shell 1 and can be slidably adjusted.

The adjusting guide shaft 53 and the adjusting spring 52 work together to adjust the cleaning force and position of the belt cleaning mechanism 5. The adjusting guide shaft 53 rotates and adjusts the crossbeam 54 of the cleaning mechanism to adjust the contact position of the cleaning belt, thereby precisely controlling the cleaning intensity and adapting to the cleaning needs of different materials. The filling plate 59 and the adjusting spring 52 help adjust the elasticity and clamping force of the cleaning mechanism to achieve a better cleaning effect. Two belt leveling components 2 are fixedly connected to the adjacent side of the two frames 3.

A base plate 47 is fixedly connected to adjacent sides of the two conveying housings 41. The scraper 46 is used to further remove residual material and push the material to the end of the conveyor belt. The base plate 47 provides support for the entire conveying system, and a pad 48 is fixedly connected to the bottom of the base plate 47.

[0029] The conveying drive assembly 6 includes a drive motor 61, which is externally fixedly connected to the front side of the conveying housing 41. A transmission wheel 64 is fixedly connected to the drive end of the drive motor 61, and a linkage rod 65 is fixedly connected to the outside of the transmission wheel 64. Another transmission wheel 64 is fixedly connected to the other end of the linkage rod 65. A protective block 62 is fixedly connected to the top of the front conveying housing 41. The drive motor 61 drives the transmission wheel 64 through the linkage rod 65, thereby driving the movement of the chain conveyor belt 44. The protective block 62 is used to protect the drive motor 61 from the influence of the external environment and ensure the stability of the motor during long-term operation. The drive motor 61 and the conveyor housing 41 are fixedly connected to the same side of the motor adjustment clip 63. The motor adjustment clip 63 is used to adjust the installation position of the motor and maintain the accuracy and stability of the drive system. The left side of the two conveyor housings 41 is fixedly connected to the cover plate 66. The auxiliary conveyor shaft 42 and the transmission wheel 64 are both provided with receiving grooves.

The external of the drive motor 61 is fixedly connected to the inside of the protective groove.

[0030] Working principle: The belt leveling assembly 2, fixed outside the frame 3, organizes the belt to enter the cleaning box housing 1. Specifically, the auxiliary mounting bracket 22 and the fixed bearing 24 cooperate to provide the necessary installation position for the leveling wheel 25, which is rotatably connected inside the two fixed bearings 24. At the same time, the leveling wheel 25 combs the belt by rotating. After the belt enters the cleaning box housing 1, multiple belt cleaning mechanisms 5 fixedly connected inside the cleaning box housing 1 scrape and clean the belt. During this process, the belt cleaning mechanism 5 can be adjusted by adjusting the position of the nut threaded to the outside of the adjusting guide shaft 53, thereby improving the practicality of the device.

[0031] The belt cleaning mechanism 5 is connected to the outside of the cleaning box shell 1 via the mounting base 51. The crossbeam 54, which is slidably connected inside the mounting base 51, serves as a crossbeam and provides necessary lateral support for the mounting beam 55, which is slidably connected to the outside of the crossbeam 54. At the same time, the two clamping blocks 56 fixed to the top of the mounting beam 55 and the cleaning plate 57 fixed to the side of the two clamping blocks 56 clean the outside of the belt so that the debris falls to the top of the subsequent waste conveying mechanism 4.

[0032] The waste material cleaned from the conveyor belt is guided by the cleaning box shell 1 and the gathering block 7 to fall onto the top of the waste conveying mechanism 4. Then, the drive motor 61 fixed to the front of the conveying shell 41 is started. The drive motor 61 drives the transmission wheel 64 fixed to the drive motor 61 to rotate. Then, through the linkage rod 65, another transmission wheel 64 is driven to rotate. The two transmission wheels 64 drive the chain conveyor belt 44 located outside the crossbeam 54 to slide, which in turn drives the multiple scrapers 46 fixed outside the chain conveyor belt 44 to slide, thereby realizing the automatic transportation of waste material, eliminating safety hazards for workers and maintaining the cleanliness of the site environment.
