Description

Technical Field

[0001] This utility model relates to the field of coal recovery, and in particular to a device for cleaning and recovering lower conveyor belts. Background Technology

[0002] Underground coal transportation primarily relies on belt conveyors. During transport, the humid underground environment causes coal slurry, coal dust, and small coal lumps to adhere to the conveyor belts, increasing belt load and causing belt misalignment, which are detrimental to transportation safety. Cleaning the belt solely with scrapers results in material waste, especially since scrapers are often located at transfer points, and the scraped coal dust and fallen coal can cause localized coal accumulation. Currently, there is no corresponding solution to this problem. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a belt cleaning and material recovery device that integrates belt cleaning and material recovery functions, avoids local coal accumulation, and fully recovers the material falling off the belt.

[0004] The equipment includes a support frame, a belt scraper system, and a coal recovery system;

[0005] The bracket is the basic assembly component of this equipment and is used to assemble under the belt conveyor during use;

[0006] The support frame is equipped with a belt scraper system and a coal recovery system;

[0007] The belt scraper system includes a trough, and a drain is provided at the bottom of the trough;

[0008] A belt scraper is provided in the material trough, and a height adjustment mechanism is provided between the belt scraper and the material trough or the support.

[0009] The effect achieved is that the height of the belt scraper is adjusted by the height adjustment mechanism so that it fits against the bottom of the lower belt; the scraped coal dust and coal chunks fall into the feed trough;

[0010] A coal recovery system is installed below the trough, which returns the coal falling from the trough to the top of the belt conveyor.

[0011] The beneficial effects of this utility model are: This utility model solves the problems of unreasonable belt scraper configuration and the uploading of scraped coal dust and fallen coal in the prior art; its configuration structure is reasonable, especially based on the integrated assembly of the equipment, the height adjustment mechanism can adjust the two scrapers separately to scrape the belt clean, and in conjunction with the linkage of the fallen coal recovery system, the fallen coal and coal dust are reloaded to avoid material waste.

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 , Figure 2 The present invention provides a belt cleaning and material recovery device, which includes a support frame, a belt scraper system and a coal recovery system.

[0018] The bracket is the basic assembly component of this equipment and is used to assemble under the belt conveyor during use;

[0019] The support frame is equipped with a belt scraper system and a coal recovery system;

[0020] The belt scraper system includes a trough 7, and the bottom of the trough 7 is provided with a drain.

[0021] A belt scraper is provided in the material trough 7, and a height adjustment mechanism 8 is provided between the belt scraper and the material trough 7 or the support.

[0022] The effect achieved is that the height of the belt scraper is adjusted by the height adjustment mechanism 8 so that it fits the bottom of the lower belt; the scraped coal dust and coal chunks fall into the feed trough 7;

[0023] A coal recovery system is installed below the trough 7, which returns the coal falling from the trough 7 to the top of the belt conveyor.

[0024] Example 1, refer to the accompanying drawings in the specification. Figure 1 The bracket is in the form of a steel frame 4, and the belt scraper system is installed on the steel frame 4.

[0025] The coal recovery system is installed on the stable support surface 1 at the lower part of the steel structure frame 4.

[0026] The effect achieved is to optimize the assembly structure and enable the equipment to operate stably and smoothly.

[0027] Example 2: The belt scraper system is provided with two scrapers, including a long scraper 6 that covers the width of the belt and a second scraper unit 5 composed of multiple short scrapers arranged alternately.

[0028] The long scraper 6 and the second scraper unit 5 are respectively mounted on the blade holder, and the blade holder is connected to the steel structure frame 4 through a height adjustment mechanism 8.

[0029] The effect achieved is that the two scrapers clean the bottom surface of the belt in sequence, and the contact pressure between the two scrapers and the belt surface can be flexibly configured based on the height adjustment of the two scrapers.

[0030] Furthermore, the height adjustment mechanism 8 is located outside the steel structure frame 4.

[0031] The effect achieved is that, based on the integrated assembly of the equipment, the two scrapers can be adjusted in height according to their length, width and wear, and thus fit the underside of the belt;

[0032] The adjustment mechanism located outside the steel frame 4 facilitates adjustment operations.

[0033] Furthermore, the height adjustment mechanism 8 is configured in the following manner:

[0034] The tool holder is provided with a screw sleeve on its side, and a screw 81 is inserted into the screw sleeve. A positioning pin is provided between the screw 81 and the screw sleeve.

[0035] In other words, the locating pin locks the screw 81 to the screw sleeve, thereby preventing the screw 81 from rotating.

[0036] The upper part of the screw 81 extends through the steel structure frame 4, and an adjusting screw sleeve 82 is provided on its upper part;

[0037] A washer is provided below the adjusting screw sleeve 82, and a spring is provided between the washer and the steel structure frame 4.

[0038] Preferably, the spring is sleeved on the screw 81.

[0039] The effect achieved is that by turning the adjusting sleeve 82, the screw 81 can be moved up and down, which in turn moves the tool holder up and down.

[0040] In Example 3, multiple nozzles are evenly arrayed in the material trough 7, and the nozzles are positioned facing downwards from the belt.

[0041] This achieves the effect of further improving the cleaning efficiency by spraying water while the scraper is running.

[0042] Example 4: The coal recovery system is configured as follows:

[0043] The material trough 7 is provided with a first auger 2 below it, and the first auger 2 is rotatably disposed in the first auger 2 shell with an open top surface;

[0044] That is, the coal falling from the feed hopper 7 falls directly into the casing where the first screw conveyor 2 is located;

[0045] At the front end of the first auger 2, a vertically positioned second auger 3 is provided, which is rotatably disposed within the shell of the second auger 3; and a coal drop outlet 31 is provided at the upper end of the shell of the second auger 3.

[0046] That is, the first auger 2 transports the coal to the bottom of the second auger 3, and the second auger 3 transports it upward to the coal drop outlet 31 to drop the coal, and then it is transported back to the upper conveyor belt.

[0047] Furthermore, the first auger 2 is powered by the first motor, and the second auger 3 is powered by the second motor.

[0048] In other words, the two augers are controlled by two separate motors. This facilitates inspection and maintenance.
