Description

Technical Field

[0001] The utility model relates to the technical field of conveying and hoisting machines, in particular to an aggregate conveying and hoisting machine. Background Art

[0002] Aggregate conveyor elevator is a kind of equipment used to transport aggregate from low to high. It is commonly used in construction sites such as concrete mixing plants and sand and gravel yards. It is usually composed of a conveyor belt, a drive device, a conveyor tower, etc. Its working principle is to transport aggregate from a low place to the feed port of the elevator through a conveyor belt, and then use the lifting function of the elevator to lift the aggregate along the conveyor tower or conveyor bucket to the target height, and finally transport the aggregate to the target position by gravity or other means.

[0003] After searching, the Chinese patent announcement number is: CN206417554U, which discloses an aggregate conveyor elevator. The key points of its technical solution are an aggregate conveyor elevator, including an inclined conveyor belt, a loading place is provided at the lower end of the conveyor belt for loading, and a receiving box is provided at the higher end of the conveyor belt for receiving materials. A scraper device is provided below the conveyor belt, and the scraper device is arranged parallel to the conveyor belt. The scraper device includes a crawler, and a plurality of scrapers are provided on the crawler. The scrapers conflict with the surface of the conveyor belt in a downward state, and the rotation direction of the crawler is opposite to the rotation direction of the conveyor belt. The aggregate conveying elevator of the utility model can clean the aggregates on the conveyor belt in time and collect them into the collecting box, thereby improving the conveying efficiency of the conveyor belt and having high safety. However, the structure between the scraper and the spring causes the device to accumulate the remaining aggregates in the corner formed by the scraper and the crawler after scraping off the remaining aggregates, and it is easy to accumulate in the dead corner. As the crawler rotates, due to the existence of the spring structure, the spring will rebound at the moment when the scraper and the rubber plate are out of contact with the conveyor belt. Before the rebound, no matter whether the spring is compressed or extended, certain problems will arise during the subsequent rebound. Utility Model Content

[0040] Reference Figure 1 and Figure 4The screening mechanism 2 includes a vertical plate 207, which is arranged at the front side of the bottom of the lifting device 1. A double-headed motor 201 is fixedly connected to the front side of the vertical plate 207, and a worm 206 is fixedly connected to the output ends of the double-headed motor 201. The left and right ends of the outer wall of the lifting device 1 are rotatably connected to worm wheels 202, which are meshed with the worm 206. A rubber hammer group 205 is fixedly connected to the rear side of the worm wheel 202. A storage box 203 is arranged in the middle of the bottom end of the lifting device 1, and a screening plate 204 is installed on the inner side of the storage box 203; air bags 22 are installed at both ends of the rubber hammer group 205; a slip ring 20 is fixedly connected to the rear side of the worm wheel 202, and annular grooves 21 are provided on the left and right sides of the front end of the outer wall of the vertical plate 207, and the slip rings 20 are slidably connected to the corresponding annular grooves 21 respectively;

[0042] Reference Figure 1 and Figure 3 The four corners of the bottom of the lifting device 1 are fixedly connected with pillars 4, and the outer walls of the pillars 4 are fixedly connected with stabilizing blocks 23; the left and right sides of the mounting frame 16 are threadedly connected with bolts 15, and the mounting frame 16 is threadedly connected with the pillars 4 through the bolts 15;

[0043] Specifically, the cooperation between the support column 4 and the stabilizing block 23 increases the stability of the equipment during operation, and the mounting frame 16 is installed and fixed by the bolts 15 .

[0044] Working principle: When scraping the residual aggregate on the lifting device 1, the adjusting knob 9 is rotated according to the inclination angle of the crawler of the lifting device 1, so as to adjust the inclination angle of the frame 5 by adjusting the knob 9. After the angle is adjusted to be consistent, the scraper 6 is taken and inserted into the slot 7. The placement position of the scraper 6 can be selected according to actual use, and the driving motor 19 is turned on to drive the active bevel gear 18 to select. The active bevel gear 18 rotates and meshes with the driven bevel gear 17 to drive the driven bevel gear 17 to rotate together with the threaded rod 13. The rotation of the threaded rod 13 drives the movable plate 10 to move up and down. When the movable plate 10 moves, the slider 11 is driven to slide in the slide groove 12 to limit the moving direction of the movable plate 10. The frame 5 is synchronously raised through the movement of the movable plate 10, so that the scraper 6 fits the bottom position of the lifting device 1. The scraper 6 is scraped by rotating the crawler on the lifting device 1. The spring does not drive the rubber The plate is stretched to scrape the material, which avoids the accumulation of aggregate in dead corners. At the same time, the frame 5 is adjusted to scrape the material in a height manner, which can adapt to a variety of different hoisting equipment and meet the needs of use. When the aggregate falls into the storage box 203, it is blocked by the screening plate 204. At the same time, the double-headed motor 201 is turned on to drive the worm 206 to rotate. The rotation of the worm 206 is meshed with the worm wheel 202 to drive the worm wheel 202 to rotate. The rotation of the worm wheel 202 causes the slip ring 20 to slide in the annular groove 21, and the rotation trajectory of the worm wheel 202 is planned. The rotation of the worm 206 causes the rubber hammer group 205 to rotate, thereby colliding with the outer wall of the storage box 203, thereby causing the aggregate on the screening plate 204 to be shaken and screened. Screening work can be performed while scraping the material, and there is no need to change the equipment for the screening process. The airbag 22 reduces the collision and noise during rotation, which brings convenience to use.
