DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figures 1 to 8 As shown, the continuous transportation device 100 for underground coal mining of the utility model comprises a bearing assembly 10 , a moving assembly 20 , a mining assembly 30 , a transportation assembly 40 and a crushing assembly 50 .

[0029] The bearing assembly 10 comprises a shell 101 , a bearing plate 103 is fixedly connected to the bottom of the shell 101 , and two sides of the bearing plate 103 are used for mounting the moving assembly 20 .

[0030] The mobile assembly 20 on one side includes a driving motor 201, a plurality of upper transmission wheels 202 and a plurality of lower transmission wheels 203. The driving motor 201 is installed on both inner sides of the carrier plate 103. The output shaft of the driving motor 201 is connected to one of the upper transmission wheels 202. The adjacent upper transmission wheels 202 are connected and transmitted through a connecting rod. The plurality of lower transmission wheels 203 are located at the bottom of the upper transmission wheels 202, and the adjacent lower transmission wheels 203 are also transmitted through a connecting rod. Among them, the outer side surfaces of the plurality of upper transmission wheels 202 and the plurality of lower transmission wheels 203 are wrapped with a crawler 204, so that the mobile assembly 20 can move stably in harsh environments.

[0031] like Figure 4 As shown, the mining assembly 30 is mounted at one end of the bearing plate 103. The mining assembly 30 includes a base 301, and a swing arm 302 is hinged on the upper part of the base 301. The swing arm 302 is an N-shaped structure, and has a middle connecting rod 302B and a side connecting rod 302A. A digging head 303 is installed at the middle connecting rod 302B, and the digging head 303 is connected to an external motor for mining ore. A swing cylinder 304 is provided on the inner side wall of the side connecting rod 302A, and the swing cylinder 304 controls the swing arm 302 to swing along the base 301 to realize multi-angle mining of ore.

[0032] Furthermore, the inner side surface of the swing arm 302 has an ore accumulation gap 302C, and the ore mined by the hoe 303 naturally falls into the ore accumulation gap 302C.

[0033] like Figures 5 to 8 As shown, the transport assembly 40 is installed above the ore accumulation gap 302C, and the transport assembly 40 includes a suction pipe 401 and a receiving frame 402. The suction pipe 401 is connected to the receiving frame 402, and the suction pipe 401 is connected to an external suction pump, which is used to suck the ore located at the ore accumulation gap 302C into the receiving frame 402. Among them, the receiving frame 402 has a feed port 402A, and the feed port 402A is connected to the suction pipe 401. The receiving frame 402 also has a first chamber 402C and a second chamber 402D, and the ore passing through the suction pipe 401 enters the first chamber 402C from the feed port 402A. The first chamber 402C and the second chamber 402D are separated by a partition 402E, and a crushing assembly 50 is arranged above the partition 402E. The crushing assembly 50 crushes the ore in the first chamber 402C and sends it to the second chamber 402D, and a discharge port 402F is arranged on one side of the second chamber 402D. There is a cavity between the shell side 101 and the bearing plate 103, and the cavity is the discharge chamber 102. The discharge port 402F is installed inside the discharge chamber 102, and a control valve 402G is also arranged on the discharge port 402F. Through the control valve 402G, the ore in the second chamber 402D is continuously transported outward, thereby improving the transportation efficiency and reducing the transportation cost of the ore.

[0034] The crushing assembly 50 includes a control motor 501, a transmission member 502 and a crushing barrel 503. The control motor 501 is installed on one side of the accommodating frame 402, and its output shaft is connected to the transmission member 502. The crushing barrel 503 is rotatably connected in the accommodating frame 402, and one end of the crushing barrel 503 is connected to the transmission member 502 to realize the transmission between the control motor 501 and the crushing barrel 503. Most of the crushing barrel 503 is located in the first chamber 402C, and is used to crush the ore in the first chamber 402C. A small part of the crushing barrel 503 is located in the second chamber 402D to prevent the crushed ore from being stuck on the partition 402E, so as to realize continuous and efficient outward transportation of ore.

[0035] Since the ore excavated by the mining assembly 30 naturally falls into the ore accumulation gap 302C, in order to ensure that the suction pipe 401 can suck most of the ore, a suction head 405 is set at the bottom of the suction pipe 401. The suction head 405 is in a trumpet shape, wherein the larger end is opposite to the ore. Furthermore, a plurality of nozzles 406 are also arranged on both sides of the suction head 405, and the nozzles 406 are connected to the pump 403 through the conduit 404. An upper support plate 402B is also arranged on the top of the accommodating frame 402, and the upper support plate 402B is used to carry the conduit 404 to prevent it from falling naturally. The nozzles 406 are installed on both sides of the suction head 405 in an inwardly inclined manner. Among them, the pump 403 delivers high-pressure airflow to the nozzle 406 through the conduit 404, gathers the ore accumulation gap 302C under the suction head 405, and sucks the ore into the accommodating chamber 402 through the suction pipe 401. The nozzles 406 on both sides are also provided with an adjusting cylinder 407, which is used to adjust the inclination angle of the nozzle 406, so that the suction area of ​​the suction pipe 401 is further increased.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
