[0002] The process loading and unloading operations of dry bulk cargo terminals such as ore, coal, and cement are characterized by a variety of cargo types and multi-level continuous transportation. Belt conveyors are relatively mature continuous conveying equipment widely used in dry bulk cargo terminals. In actual operation, there is a common problem of material leakage on the return belt of belt conveyors. There are two reasons for this. One is abnormal material spillage caused by belt deviation or hopper damage, and the accumulated material is located around the belt conveyor frame or hopper; the other is the material on the return belt, and the accumulated material is located under the belt conveyor. Among them, most of the accumulated material is generated by the return belt. Continuous material carrying and material spillage will cause long-term cleaning of accumulated material, which requires a lot of manpower and material resources to maintain. The material carrying problem will cause poor environmental hygiene around the belt conveyor and even affect the safe operation of the equipment. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0018] like Figure 1-3 As shown, a device for collecting spilled materials of a belt conveyor comprises a sweeper 1, which is arranged at the return belt 2 of the belt conveyor, the blade length of the first scraper 3 of the sweeper 1 matches the width of the return belt, and the blade surface of the first scraper 3 matches the surface of the return belt 2; a limiting device 4 is provided adjacent to one side of the sweeper 1 along the moving direction of the return belt, which is specifically arranged on the right side of the sweeper 1, and the adjacent arrangement is for timely cleaning after the accumulated materials are loosened, the limiting device 4 comprises a bracket 5, and two relatively arranged limiting parts 6 for limiting the return belt are provided on the bracket 5, because the return belt always shakes to varying degrees when returning, the limiting parts 6 are provided to prevent the belt from shaking left and right and up and down, so as to facilitate cleaning by the sweeper 1, and an air jet device is provided between the two limiting parts 6, and a bracket 7 is provided at the bottom of the return belt 2 for collecting the accumulated materials swept by the sweeper or sprayed by the air jet device, so as to facilitate recovery and prevent accumulation of materials in the corridor of the belt conveyor, and a material drop opening 8 is provided below the redirecting roller 9 of the belt conveyor.

[0019] In order to scrape off the accumulated materials on the return belt, the cleaner 1 includes a cleaner rod 12, a first scraper 3 and a cleaner bracket 10. Two cleaner brackets 10 are arranged on both sides of the return belt 2. A cleaner rod 12 is fixed between the two cleaner brackets 10. A plurality of first scrapers 3 are arranged on the cleaner rod 12. The blade surface of the first scraper 3 is flattened into a plane, which matches the return belt 2. The blade body of the first scraper 3 is fixed to the cleaner rod 12 by bolts.

[0020] In order to disperse the accumulated materials on the return belt before scraping, the jet device includes a hollow base 13 arranged on the bracket 5, and a plurality of nozzles 14 are arranged on the hollow base 13 at equal intervals. An air inlet 15 is arranged on one side of the hollow base 13, and the air inlet 15 is connected to the air supply device through an air pipe. In order to prevent the return belt from being scratched by the nozzle, the nozzle surface of the nozzle is set in an arc, and the space formed by the nozzle and the top of the limit part 6 is adapted to the return belt 2. The nozzle is close to the return belt to increase the pressure of the ejected gas, and the stubborn accumulated materials are dispersed by high-pressure gas, which is convenient for subsequent scraper cleaning. The gas pressure can be adjusted by the air supply device before the device is activated, so that the accumulated materials are not splashed and the accumulated materials can be loosened.

[0021] In order to prevent the return belt from jumping, a support roller 16 is provided adjacent to the limit device 4 away from the sweeper 1. The support roller 16 can press the return belt while dragging the return belt 2. In cooperation with the limit device 4, the return belt can be more stable when being cleaned by the sweeper 1. In order to enable the scraped accumulated materials to automatically flow to the drop hopper, a further preferred technical solution is that the bracket 7 is arranged in an inclined surface, the highest point of the bracket 7 is located below the sweeper, and the lowest point is located at the drop port 8. The accumulated materials slide into the drop port 8 by themselves through the gravity of the inclined surface, saving resources and improving the utilization efficiency of materials. In order to be able to preliminarily scrape off the thick accumulated materials, the drop port 8 is close to the edge of the return belt 2. The second scraper is set to preliminarily scrape off the thick accumulated materials that have not fallen, reducing the workload of the subsequent scrapers, which is equivalent to one for preliminary processing and one for fine processing.

[0022] The working process of the utility model is as follows: the return belt 2 first passes through the second scraper 11 to scrape off the thicker accumulated materials remaining on the return belt 2. The accumulated materials here are generally loose and can be directly scraped off by an ordinary scraper. Then, the belt is pressed by the supporting roller 16, and the limit part 6 limits the sliding of the belt. At the same time, the jet device sprays gas to disperse the stubborn accumulated materials on the return belt 2. The dispersed accumulated materials are collected by the first scraper 3 and scraped into the bracket 7, and automatically slide to the drop port 8 by gravity.

[0023] The utility model discloses the utility model discloses the return belt is limited to the middle by setting the limit device, and prevents it from jumping repeatedly, thus being convenient for the cleaning of the rear sweeper. At the same time, the air blowing device is used to blow loose the stubborn accumulated materials in the gap of the return belt, thus improving the cleaning effect of the rear sweeper. It does not increase the extra power consumption, has the advantages of simple structure and reasonable layout, is convenient for cleaning the accumulated materials, can solve the problem of returning the materials and cleaning the accumulated materials to the greatest extent, and saves manpower and material resources.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
