Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaning equipment, in particular to a self-pressing second-stage belt cleaner for a belt conveyor. Background Art

[0002] In order to reduce the accumulation of materials adhered to the return belt and scattered on the ground and the aggravated wear of the belt, at present, special cleaners are generally installed at the cleaning points of the return belt of the belt conveyor. A scraper with its upper edge close to the return belt is installed perpendicular to the running direction of the belt conveyor on the cleaner, which can be used to scrape and clean the return belt at a fixed point as it runs. Then, the materials cleaned and concentrated are transported away at one time after accumulating to a certain amount. Although the above-mentioned special cleaner can clean the return belt, it is found in use that the scraper will be continuously worn and gradually shortened during the cleaning process, so that the gap between the scraper and the belt becomes larger and larger. When the scraper cannot be close to the return belt, it is necessary to stop the operation of the belt conveyor, and the maintenance personnel need to lift the scraper upward in time to reduce the gap until it cannot be lifted due to wear and then replace the whole scraper to ensure the normal operation of the belt cleaner; once the adjustment is not timely, the cleaning will not be successful; in addition, the scraper of the cleaner is currently an integral structure, and when a certain section is damaged, the whole scraper must be replaced, wasting resources.

[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further detailed description of the utility model is provided in conjunction with the drawings and embodiments. The specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0022] Such as Figures 1 to 5As shown in the figure, this embodiment exemplarily shows a self - pressing second - stage belt cleaner for a belt conveyor, which is installed in a funnel under the belt of the belt conveyor. It includes a cleaner body 1, and the cleaner body 1 is composed of an installation steel pipe 102 and a cleaning blade 101. The top of the cleaning blade 101 is in contact with the belt; both ends of the installation steel pipe 102 are provided with installation frames 2 installed on the outer side wall of the funnel. The installation frame 2 includes a first right - angle plate 201 and two second right - angle plates 202 arranged perpendicular to the first right - angle plate 201. Both ends of the first panel of the first right - angle plate 201 are fixedly connected to the top ends of the first panels of the two second right - angle plates 202. Vertical third right - angle plates 203 are respectively installed on the outer side walls of the two second right - angle plates 202. The first panel of the third right - angle plate 203 is fixedly connected to the outer side wall of the second panel of the second right - angle plate 202, and the second panel of the third right - angle plate 203 is fixed on the outer wall of the funnel; a U - shaped notch 8 is formed between the two second right - angle plates 202. A sleeve 3 fixed outside the end of the installation steel pipe 102 is arranged in the U - shaped notch 8. During the actual installation process, a plurality of threaded holes are opened on the sleeve 3, and the sleeve 3 is fixed to the installation steel pipe 102 with screws; vertical strip - shaped holes 9 for the ends of the installation steel pipe 102 to pass through are opened on both side walls of the funnel. The length of the vertical strip - shaped hole 9 is greater than or equal to the depth of the U - shaped notch 8. A sealing plate 7 is fixed on the installation steel pipe 102 outside the vertical strip - shaped hole 9. The sealing plate 7 is close to the outer side wall of the funnel and always blocks the vertical strip - shaped hole 9. Specifically, during the up - and - down movement of the sealing plate 7, it can always cover the vertical strip - shaped hole 9. The sealing plate 7 is a sufficiently large rectangular plate; a screw rod 4 is vertically welded to the top end of the sleeve 3. The top end of the screw rod 4 passes through a through - hole opened at the center of the second panel of the first right - angle plate 201. A compression spring 5 is sleeved on the screw rod 4 above the second panel of the first right - angle plate 201. A locking nut 6 is installed at the top end of the screw rod 4. It should be noted that the selected compression spring 5 in this embodiment can not only ensure that the pressure between the cleaning blade 101 of the cleaner and the belt is within a reasonable range, that is, ensure the scraping and cleaning effect, but also prevent excessive tightness and unnecessary excessive wear. In addition, since the installation frame 2 of this embodiment is arranged on the outer side wall of the funnel, during the actual use process, the relative position between the sleeve 3 and the second panel of the first right - angle plate 201 can be used to judge whether the cleaning blade 101 needs to be replaced. For example, the initial distance between the sleeve 3 and the second panel of the first right - angle plate 201 is set to 3 cm. When the distance between the sleeve 3 and the second panel of the first right - angle plate 201 is less than 1 cm, it means that the cleaning blade 101 needs to be replaced.

[0023] As Figure 5 shown, the sealing plate 7 is slidably assembled between the first panels of the two third right - angle plates 203. The first panels of the two third right - angle plates 203 play a guiding role on both sides of the sealing plate 7, and there will be no excessive gap between the sealing plate 7 and the side wall of the funnel.

[0024] As Figure 6 、Figure 7 As shown, the cleaning blade 101 of this embodiment is composed of several cleaning blade segments 1011. An installation groove 1014 is provided at the bottom of the cleaning blade segment 1011. The installation groove 1014 is matched with the rib 103 axially installed on the installation steel pipe 102. The cleaning blade segment 1011 is fixed on the rib 103 by bolts and nuts. One end of the cleaning blade segment 1011 is provided with a connecting column 1012, and the other end is provided with a column groove 1013 matched with the connecting column. When one or several of the cleaning blade segments 1011 are severely worn, only the local cleaning blade segment 1011 needs to be replaced, and there is no need to replace the entire cleaning blade.

[0025] During use, the distance between the top end of the cleaning blade 101 and the belt is adjusted by adjusting the lock nut. Due to the spring-back effect of the compression spring 5, when the cleaning blade 101 wears, it will drive the cleaning blade 101 on the installation steel pipe 102 to move upward to ensure the pressure between the cleaning blade 101 of the cleaner and the belt. For example, the initial distance between the sleeve 3 and the second panel of the first right-angle plate 201 is set to 3 cm. When the distance between the sleeve 3 and the second panel of the first right-angle plate 201 is less than 1 cm, it indicates that the cleaning blade 101 needs to be replaced. At this time, only the cleaning blade segment 1011 needs to be replaced. Since the sealing plate 7 is installed on the installation steel pipe 102, the sealing plate 7 moves up and down with the cleaner. The sealing plate 7 closely adheres to the outer wall of the funnel and always blocks the vertical strip-shaped holes 9, preventing the materials scraped from the belt from escaping from the vertical strip-shaped holes 9 on both sides of the funnel, which is more environmentally friendly.

[0026] The technical solution of the present invention is not limited to the limitations of the above specific embodiments. Any technical deformation made according to the technical solution of the present invention falls within the protection scope of the present invention.
