Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and particularly relates to a belt conveyor blanking cleaning device. Background Technique

[0002] A belt conveyor is a commonly used device in material transportation. When some materials return on the belt conveyor after unloading, it is inevitable that residual materials will adhere to the surface of the conveyor belt. If the adhered materials are not cleaned in time, they are likely to accumulate continuously during subsequent transportation, thereby affecting the transportation efficiency of the belt conveyor. Therefore, a belt conveyor blanking cleaning device is required.

[0003] In the patent application with the authorization publication number CN220097613U, the authorization publication date of November 28, 2023, and the name of "Belt Conveyor Blanking Cleaning Device and Belt Conveyor", the belt conveyor blanking cleaning device is installed in the unloading section of the belt conveyor. The unloading section includes an upper belt for carrying slag and a lower belt after rotation. The blanking cleaning device includes a discharge hopper and a scraper. The discharge hopper is arranged below the lower belt and is used to receive the slag output from the unloading section of the belt conveyor. The scraper is arranged between the lower belt and the discharge hopper. The scraper extends along the width direction of the lower belt. One side of the scraper is used to contact the lower belt to scrape the slag remaining on the lower belt into the discharge hopper. The utility model scrapes the slag remaining on the lower belt into the discharge hopper through the scraper to realize the cleaning of the slag adhered to the lower belt.

[0004] When the existing belt conveyor blanking cleaning device is in use, although it can scrape off the materials attached to the conveyor belt, the scraped-off materials cannot be re-fed onto the conveyor belt for transportation, resulting in a great waste of the scraped-off materials and inconvenience in use. Therefore, we propose a belt conveyor blanking cleaning device to solve the problems raised above. Content of the Utility Model

[0005] 1. Technical problems to be solved by the utility model:

[0006] The purpose of the utility model is to provide a belt conveyor blanking cleaning device to solve the problems in the current market proposed in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A belt conveyor blanking cleaning device includes a frame. A conveyor belt is arranged inside the frame. A receiving hopper is installed inside the frame corresponding to the lower part of the conveyor belt. Among them,

[0009] A scraping mechanism is provided inside the receiving hopper corresponding to one end of the conveyor belt. A return material cylinder is installed on the outer side of the frame away from the scraping mechanism. A spiral feeding rod is rotatably connected inside the return material cylinder. A motor is installed on the top of the return material cylinder, and the shaft end of the motor is fixedly connected to the spiral feeding rod.

[0010] One end of the receiving hopper close to the return material cylinder is communicated with a feed pipe at the bottom. The end of the feed pipe away from the receiving hopper is communicated with the return material cylinder. The return material cylinder is communicated with a discharge pipe on one side above the conveyor belt.

[0011] Preferably, the scraping mechanism includes a fixing frame. The fixing frame is fixedly connected to the inner side of the receiving hopper away from the feed pipe. A scraper is arranged on the side of the fixing frame close to the conveyor belt. Guide rod grooves are symmetrically penetrated on the fixing frame. Guide rods are fixedly connected to the side of the scraper corresponding to the guide rod grooves. Springs are sleeved on the guide rods between the scraper and the fixing frame.

[0012] Preferably, one end of the scraper away from the fixing frame abuts against the lower surface of the conveyor belt through a spring.

[0017] 3. Beneficial effects:

[0018] Adopting the technical solution provided by the present utility model, compared with the prior art, the belt conveyor blanking cleaning device of the present utility model is as follows:

[0019] (1) When the material is conveyed by the conveyor belt, the material falls from the end of the conveyor belt. When the material attached to the conveyor belt passes through the scraping mechanism, the material attached to the lower surface of the conveyor belt is scraped off by the scraping mechanism, so that the material falls into the receiving hopper. The material falling from both sides during the conveyor belt conveying also falls into the receiving hopper, so that the material in the receiving hopper flows along the inclined bottom toward the feed pipe. At the same time, the motor drives the spiral feeding rod to rotate. After the material enters the return material cylinder through the feed pipe, the spiral feeding rod drives the material to move upward and falls back onto the top of the conveyor belt through the discharge pipe. Through this belt conveyor blanking cleaning device, the falling material can be cleaned and re-conveyed onto the conveyor belt, avoiding waste.

[0020] (2) The end of the scraper is pressed against the lower surface of the conveyor belt by a spring. When the conveyor belt is working, relative movement occurs between the scraper and the conveyor belt. The scraper can scrape off the materials adhering to the lower surface of the conveyor belt. At the same time, due to the elastically arranged scraper, it is possible to avoid an increase in the gap between the scraper and the conveyor belt caused by wear of the scraper, enabling the scraper to always press against the conveyor belt and effectively improving the scraping effect on the conveyor belt.

[0030] Please refer to Figures 1 to 4 , a belt conveyor material dropping and cleaning device, which includes a frame 1. A conveyor belt 2 is arranged inside the frame 1. A receiving hopper 3 is installed inside the frame 1 corresponding to the lower side of the conveyor belt 2. Among them,

[0031] A scraping mechanism is arranged inside the receiving hopper 3 corresponding to one end of the conveyor belt 2. A return material cylinder 9 is installed on the outer side of the frame 1 away from the scraping mechanism. A spiral feeding rod 10 is rotatably connected inside the return material cylinder 9. A motor 11 is installed on the top of the return material cylinder 9, and the shaft end of the motor 11 is fixedly connected to the spiral feeding rod 10;

[0032] One end of the bottom of the receiving hopper 3 close to the return material cylinder 9 is communicated with a feeding pipe 12. One end of the feeding pipe 12 away from the receiving hopper 3 is communicated with the return material cylinder 9. One side of the return material cylinder 9 close to the upper side of the conveyor belt 2 is communicated with a discharge pipe 13;

[0033] When the material is conveyed by the conveyor belt 2, the material falls from the end of the conveyor belt 2. When the material attached to the conveyor belt 2 passes through the scraping mechanism, the material attached to the lower surface of the conveyor belt 2 is scraped off by the scraping mechanism, so that the material falls into the receiving hopper 3. The material falling from both sides during the conveyance of the conveyor belt 2 also falls into the receiving hopper 3, making the material in the receiving hopper 3 flow along the inclined bottom towards the feeding pipe 12. At the same time, the motor 11 drives the spiral feeding rod 10 to rotate. After the material enters the return material cylinder 9 through the feeding pipe 12, the spiral feeding rod 10 drives the material to move upward and re-falls onto the top of the conveyor belt 2 through the discharge pipe 13. Through this belt conveyor material dropping and cleaning device, the dropped material can be cleaned and re-conveyed onto the conveyor belt 2 to avoid waste.

[0034] Please refer to Figures 1 to 4, the scraping mechanism includes a fixed frame 4. The fixed frame 4 is fixedly connected to the inner side of the material receiving hopper 3 away from the feed pipe 12. A scraper 5 is arranged on the side of the fixed frame 4 close to the conveyor belt 2. Guide rod grooves 6 are symmetrically penetrated through the fixed frame 4. A guide rod 7 is fixedly connected to the side of the scraper 5 corresponding to the guide rod groove 6. A spring 8 is sleeved on the guide rod 7 between the scraper 5 and the fixed frame 4. One end of the scraper 5 away from the fixed frame 4 abuts against the lower surface of the conveyor belt 2 through the spring 8. The guide rod 7 is a cylinder, and the guide rod 7 and the guide rod groove 6 form a guiding structure. The end of the scraper 5 abuts against the lower surface of the conveyor belt 2 through the spring 8. When the conveyor belt 2 is working, relative movement is generated with the scraper 5. The material attached to the lower surface of the conveyor belt 2 can be scraped off by the scraper 5. At the same time, through the elastically arranged scraper 5, it is avoided that the gap between the scraper 5 and the conveyor belt 2 increases due to wear of the scraper 5, so that the scraper 5 can always abut against the conveyor belt 2, effectively improving the scraping effect on the conveyor belt 2.

[0035] Please refer to Figures 1 to 4 , the inner bottom of the material receiving hopper 3 is inclined, and the inner bottom of the material receiving hopper 3 is inclined downward toward the feed pipe 12. The feed pipe 12 is inclined downward from the material receiving hopper 3 to the return material cylinder 9. The discharge pipe 13 is inclined downward from the return material cylinder 9 to the conveyor belt 2. When the material falls into the interior of the material receiving hopper 3, through the inclined inner bottom of the material receiving hopper 3, it is convenient for the material to flow toward the feed pipe 12, and through the inclined feed pipe 12, it is convenient for the material to enter the return material cylinder 9. When the material in the return material cylinder 9 enters the discharge pipe 13, the material can fall onto the upper side of the conveyor belt 2 along the inclined discharge pipe 13.

[0036] Working principle: When using this belt conveyor blanking and cleaning device, as Figures 1 to 4As shown, first, when the material is transported by the conveyor belt 2, the material falls from the end of the conveyor belt 2, and when the material attached to the conveyor belt 2 passes through the scraper mechanism, the material attached to the lower surface of the conveyor belt 2 is scraped off by the scraper mechanism, so that the material falls into the receiving hopper 3, and the material falling from both sides of the conveyor belt 2 also falls into the receiving hopper 3, so that the material in the receiving hopper 3 flows along the inclined bottom toward the feed pipe 12, and at the same time, the motor 11 drives the spiral feeding rod 10 to rotate. After the material passes through the feed pipe 12 and enters the return tube 9, the material is driven to move upward by the spiral feeding rod 10 and passes through the discharge The tube 13 falls back to the top of the conveyor belt 2. Through the belt conveyor falling material cleaning device, the fallen materials can be cleaned and re-conveyed to the conveyor belt 2 to avoid waste. The end of the scraper 5 is pressed against the lower surface of the conveyor belt 2 through the spring 8. When the conveyor belt 2 is working, it moves relative to the scraper 5. The scraper 5 can scrape off the material attached to the lower surface of the conveyor belt 2. At the same time, the elastically set scraper 5 can prevent the scraper 5 from wearing and causing the gap with the conveyor belt 2 to increase, so that the scraper 5 can always press against the conveyor belt 2, effectively improving the scraping effect of the conveyor belt 2, thereby completing a series of tasks.
