Description

Technical Field

[0001] This utility model belongs to the field of coal truck residual coal recovery technology, specifically relating to a new residual coal recovery device for tamping coal trucks. Background Technology

[0002] In the field of coal mining equipment, coal is fed by a vibrating feeder and finally falls into the coal box of a tamping loading car. The tamping machine tamps the washed coal into coal cakes, and then uses a coal support plate to send the coal cakes into the carbonization chamber. Tamping work refers to the mechanical work done by the tamping hammers on the coal cakes, generally expressed as tamping unit work, that is, the work done on a unit weight of coal cake. Tamping unit work is related to factors such as the weight, stroke, frequency, and number of tamping hammers.

[0003] During the operation of existing tamping coal feeding vehicles, excess coal often falls to the ground, requiring manual collection. This not only increases the labor intensity of workers but may also lead to resource waste. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 This utility model provides the following technical solution: A novel residual coal recovery device for a tamping coal loading car, comprising: a recovery bin 1, a material inlet 2 at the top of the recovery bin 1, a sealing ring 3 fitted onto the inner wall of the opening at the top of the material inlet 2, the top of the sealing ring 3 abutting against a top cover 4, a first bolt 5 longitudinally penetrating the top of the top cover 4, the bottom of the first bolt 5 being threadedly connected to the material inlet 2, an air inlet pipe 6 and an air outlet pipe 7 respectively provided at both ends of the lower side wall of the recovery bin 1, a second bolt 8 transversely penetrating the opening end of the other side of the air inlet pipe 6, and the second bolt 8 being threadedly connected to the side wall of the second bolt 8. The filter pipe 9 is connected to the air outlet of the suction fan 11 via a third bolt 10 on the other side. The bottom of the suction fan 11 is installed on the top of one side of the trolley 12. The outlet end of the air outlet pipe 7 is transversely connected to the fourth bolt 13 and threaded to the connecting pipe 14. The other side of the connecting pipe 14 is threaded to the material collection cover 15. The top of the material collection cover 15 is provided with a connecting plate 16. The side wall of the connecting plate 16 is rotatably connected to the rotating shaft 17. The surface of the rotating shaft 17 is rotatably connected to the moving rod 18. In this design, the suction fan 11 is existing technology, and its model is: 4-72 centrifugal fan. Since it is existing technology and is not related to this design, it will not be described in detail here.

[0023] The preferred configuration consists of a recycling bin 1, a material inlet 2, a sealing ring 3, a top cover 4, and a first bolt 5 forming a threaded connection structure.

[0024] In practical use, the first bolt 5, which is fixed between the feed inlet 2 and the top cover 4, can be unscrewed to remove the sealing ring 3 and the top cover 4, thus facilitating the cleaning of residual coal from the feed inlet 2.

[0025] Preferably, the air inlet pipe 6, the air outlet pipe 7, the second bolt 8, the filter pipe 9, the third bolt 10, and the suction fan 11 form a threaded connection structure.

[0026] In actual use, unscrew the second bolt 8 and the third bolt 10 on both sides of the filter tube 9 to facilitate the disassembly and replacement of the filter tube 9.

[0027] Preferably, both the air inlet pipe 6 and the filter pipe 9 have filter screens installed on their inner walls.

[0028] In practical use, the filter screens installed on the inner walls of the air inlet pipe 6 and the filter pipe 9 are used to intercept the collected coal slag and prevent it from entering the suction fan 11.

[0029] Preferably, the receiving cover 15 is provided with a threaded tube on the rear side, and the shape and size of the threaded tube are adapted to the threaded structure on one side of the connecting tube 14.

[0030] In practical use, the threaded tube at the rear end of the receiving cover 15 facilitates the connection of the connecting tube 14 to it, thereby making it easy to disassemble and fix the connecting tube 14 and the receiving cover 15.

[0031] Preferably, the receiving cover 15 has a rectangular opening at the front end and a triangular scraper at the bottom of the front end of the receiving cover 15. The receiving cover 15, the connecting plate 16, the rotating shaft 17 and the moving rod 18 form a rotating connection structure.

[0032] In practical use, hold the moving rod 18 and use the pivot 17 at its front end connected between the receiving cover 15 and the moving rod 18 to easily lift the receiving cover 15 and adjust its angle.

[0033] Working principle: When the tamping and loading car is running, the pusher 12 is moved to the position where the remaining coal falls by using the lever on one side of the pusher 12. Then, the receiving hood 15, which is rotatably connected to the front end of the moving rod 18, is lifted. A connecting pipe 14 of appropriate length is then connected between the receiving hood 15 and the exhaust pipe 7, based on the distance the remaining coal has fallen. Afterward, the suction fan 11 is started to draw air, and the receiving hood 15 is moved to the position where the remaining coal has fallen by holding the moving rod 18. The suction between the connecting pipe 14 and the filter pipe 9 connecting the suction fan 11 and the receiving hood 15 collects the fallen remaining coal. The collected remaining coal is temporarily... The coal is stored in the recycling bin 1. During the collection process, if lumps or large coal pieces are encountered, the scraper at the bottom front of the collection hood 15 can be used to break and knock them down, thereby preventing large coal pieces from clogging the pipe. The collection hood 15 can also be disassembled and replaced regularly to prevent wear and tear on the scraper from affecting its use. At the same time, the filter screens installed in the air inlet pipe 6 and the filter pipe 9 intercept coal slag and prevent it from entering the suction fan 11. After collection is completed, the first bolt 5 fixed between the feed port 2 and the top cover 4 can be unscrewed to remove the sealing ring 3 and the top cover 4, making it easy to clean up the remaining coal from the feed port 2.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
