Description

Technical Field

[0001] The utility model relates to the field of mining belt cleaning, in particular to an anti-blocking mud discharge device of a mining belt cleaning machine. Background Art

[0002] Mining belt conveyor is also called belt conveyor. The conveyor belt moves according to the principle of friction transmission. It is easy to take out powdery, granular, small-block low-abrasive materials and bagged materials, such as coal, gravel, sand, cement, fertilizer, grain, etc. When conveying muddy and sticky materials with high moisture content, the conveyor belt is not cleaned properly, causing the conveyor belt to deviate, scatter materials, and the carrying capacity to fail to meet the design requirements. Due to unclean unloading, there will often be muddy and sticky materials on the conveyor belt surface, which will accumulate more and more and eventually cause the belt to deviate. Therefore, the belt often needs to be cleaned.

[0003] According to the patent CN212475082U, a mud discharge device of a mining belt cleaning machine includes a base plate, a cleaning mechanism, a mud collecting box and a bracket. Two groups of hydraulic cylinders are installed on the upper surface of the base plate in a vertically symmetrical distribution. The upper ends of the hydraulic cylinders are connected to the bottom end faces of the horizontally arranged fixed plates. The fixed plates are parallel to the base plate. The upper surface of the base plate is located below the cleaning wheel and is also obliquely provided with a mud collecting box. The opening of the mud collecting box faces upward. The cleaning mechanism includes a cleaning wheel, a driving motor and a support rod. The cleaning wheel is a horizontally arranged cylindrical structure, and both side walls are protruding with an integral structure having a rotating shaft. The rotating shaft rotates synchronously with the cleaning wheel, and the end of the rotating shaft away from the cleaning wheel is also rotatably connected to the clamping plate, and the clamping plate is It is said that they are distributed on both sides of the cleaning wheel, and the clamping plate is also fixedly connected to one end of the support rod. In the process of realizing the utility model, the inventor found that there are at least the following problems in the prior art that have not been solved. Through the arrangement of the cleaning wheel and the mud collecting box, the sludge and sewage generated by the cleaning can be collected while cleaning the mining belt conveyor to prevent it from dripping everywhere, thereby effectively protecting the on-site environment. During use, the traditional method requires cleaning when the belt stops conveying materials, so that it cannot be used during cleaning, thereby affecting the efficiency of material transportation, and the existing method directly sprays water through the nozzle for flushing. Since there is no protective mechanism on the outside, sewage splashing is easily generated when flushing the belt. For this reason, it is necessary to design a new technical solution to solve this problem. Utility Model Content

Detailed implementation mode

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0022] Embodiment 1: A sludge discharge device for preventing blockage of a mine belt cleaning machine, see Figures 1 to 7, including a rectangular collecting hopper 1, a bracket 13 is fixedly connected to the bottom of the rectangular collecting hopper 1, a rectangular frame 11 is fixedly connected to the top of the rectangular collecting hopper 1, notches 12 are formed on both sides of the rectangular frame 11, a cover plate 14 is arranged on the top of the rectangular frame 11, bolts 15 penetrate through the four corners of the top of the cover plate 14, and the four bolts 15 are all threadedly connected to the surface of the rectangular frame 11; scraping plates 41 are arranged on both sides of the inner cavity of the rectangular frame 11, partition plates 4 are arranged at the opposite ends of the two scraping plates 41, and the two partition plates 4 are both fixedly connected to the bottom end of the inner cavity of the rectangular collecting hopper 1. Connecting shafts 29 are rotatably connected to both sides of the inner cavity of the rectangular frame 11 between the two partition plates 4. A cleaning roller 21 is installed between the two connecting shafts 29. The connecting shafts 29 and the cleaning roller 21 are both of hollow structures, and the connecting shafts 29 and the cleaning roller 21 communicate with each other. A plurality of cleaning brushes 211 are installed on the outer side of the cleaning roller 21. A driving motor 2 is arranged at one end of the outer side of the rectangular frame 11. The driving end of the driving motor 2 is connected to the connecting shaft 29. A rotary joint 23 is installed at one end of the rectangular frame 11 away from the driving motor 2, and the rotary joint 23 is connected to the connecting shaft 29. A water inlet pipe 24 is communicated with the outer side of the rotary joint 23. A plurality of water spraying holes 28 are formed on the outer side of the cleaning roller 21. The plurality of water spraying holes 28 and the plurality of cleaning brushes 211 are alternately distributed on the outer side of the cleaning roller 21. During operation, the rectangular collecting hopper 1 is moved below the belt conveyor so that the belt is placed in the notch 12, and then the bolts 15 are screwed to fix the cover plate 14 on the top of the rectangular frame 11, so that a part of the belt is placed in the rectangular frame 11, so that the scraping plates 41 and the cleaning brushes 211 are in contact with the bottom surface of the belt. Then the driving motor 2 is started to drive the cleaning roller 21 to rotate and cooperate with the cleaning brushes 211 to brush the belt, so that the scraping plates 41 and the cleaning brushes 211 can clean the materials adhered to the return belt, and thus there is no need to stop the machine to clean the belt, thereby improving the efficiency of the belt conveying materials. When brushing the belt, the water inlet pipe 24 is connected to the water source, so that the water can be sprayed on the surface of the belt from the inside of the rotating cleaning roller 21 through the water spraying holes 28 in cooperation with the rotary joint 23, so as to improve the cleaning effect of the belt in cooperation with the cleaning brushes 211. Since the belt is rinsed inside the rectangular frame 11, a large amount of sewage splashing during rinsing is avoided, thus preventing pollution.

[0023] Specifically, refer to Figure 1 — Figure 3 , sludge discharge pipes 31 are communicated with both sides of the rectangular collecting hopper 1, a sewage discharge pipe 32 is communicated with the bottom of the rectangular collecting hopper 1, an arc-shaped filter screen 33 is fixedly connected between the two partition plates 4 below the cleaning roller 21, sludge discharge holes are formed at both ends of the rectangular collecting hopper 1, and sealing covers 3 are threadedly connected in the two sludge discharge holes. The materials scraped by the scraping plates 41 and the materials cleaned by the cleaning brushes 211 are separated and discharged through the partition plates 4.
