Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0032] In the description of this invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] Please refer to Figures 1 to 7 The present invention provides a combined end mechanism for connecting a scraper conveyor and a transfer conveyor, including a scraper conveyor head 01 and a transfer conveyor tail trough 02;

[0034] The scraper conveyor head 01 includes a head groove 11 and a bottom plate 12, a middle plate 13, and an upper plate 14 installed sequentially from bottom to top within the head groove 11. A lower scraper conveyor chain path 15 is formed between the bottom plate 12 and the middle plate 13, and an upper scraper conveyor chain path 16 is formed between the upper plate 14 and the head groove 11. A lower vertical plate 17 is provided between the bottom plate 12 and the bottom of the head groove 11, arranged opposite each other along the short side of the head groove 11. The lower vertical plate 17 and the bottom plate 12, and... The bottom of the head trough 11 forms the lower chain path 18 of the transfer machine. An upper vertical plate 19 is arranged opposite to the head trough 11 along the short side direction between the middle plate 13 and the upper plate 14. The upper chain path 20 of the transfer machine is formed between the upper vertical plate 19 and the upper plate 14. A gap for coal blocks to fall is formed on the upper plate 14. When the scraper conveyor transports the coal blocks, the coal blocks can fall into the tail trough 02 of the transfer machine through the gap formed on the upper plate 14, and then be transported by the transfer machine.

[0035] Of course, in order to ensure that the coal flow can form an effective obstruction and change direction, a plow plate 06 is installed on the head trough 11. This technology is existing technology, and its specific structure will not be described in detail here.

[0036] The tail section 02 of the transfer machine includes a first connecting groove 21 and a second connecting groove 22. The first connecting groove 21 is connected to the head section 11 and the two are installed in a T-shape, so that the first connecting groove 21 can be connected to the upper chain track 20 and the lower chain track 18 of the transfer machine. The second connecting groove 22 is connected to the first connecting groove 21, and the second connecting groove 22 is rotatably connected to the end of the first connecting groove 21 away from the head section 11, so that the second connecting groove 22 can swing left and right with the end of the first connecting groove 21.

[0037] By using a rotating connection between the second connecting groove 22 and the first connecting groove 21, the relative angle between the scraper conveyor and the transfer conveyor can be adjusted, thereby regulating the coal flow turning resistance and improving the flexibility of equipment layout in the underground working face. During operation, this ensures smooth coal flow at the junction of the scraper conveyor and the transfer conveyor, reducing turning resistance and thus lowering power consumption. Furthermore, when congestion occurs at the junction, the second connecting groove 22 can be controlled to continuously swing left and right with the centerline of the first connecting groove 21 as a reference, with an amplitude between 0-10°. This left-right swinging of the second connecting groove 22 loosens the coal lumps congested at the junction, allowing the transfer conveyor's scrapers and scraper chain to quickly transport the coal away, ensuring smooth coal flow.

[0038] Please refer to Figure 8 , Figure 9 In one embodiment, the first connecting groove 21 includes a telescopic protective plate 04211 mounted opposite to one side of the head groove 11, and a lower plate 212, a middle plate 213, and an upper plate 214 mounted between the telescopic protective plates 04211. The lower plate 212 is connected to the bottom of the head groove 11, and the middle plate 213 is connected to the middle plate 13 inside the head groove 11. A lower channel is formed between the middle plate 213, the lower plate 212, and the telescopic protective plate 04211, and the lower channel is connected to the lower chain path 18 of the transfer machine. The upper plate 214 is connected to the upper plate 224 of the head groove 11, and an upper channel 216 is formed between the upper plate 224 and the telescopic protective plate 04211, and the upper channel 216 is connected to the upper chain path 20 of the transfer machine. The retractable protective plate 04 can prevent coal blocks from scattering out, while the coal blocks conveyed by the scraper conveyor can fall into the upper chain track 20 of the transfer machine through the gap formed on the upper plate 14.

[0039] Specifically, the telescopic protective plate 04211 includes a fixed base 2111, an arc-shaped plate 2112, and a movable plate 2113. The fixed base 2111 is installed opposite to one side of the machine head groove 11, the arc-shaped plate 2112 is installed at the end of the fixed base 2111 away from the machine head groove 11, and the movable plate 2113 is slidably connected to the arc-shaped plate 2112. One end of the movable plate 2113 is hinged to the second connecting groove 22. When the second connecting groove 22 swings left and right, it can drive the movable plate 2113 to slide and extend along the arc-shaped plate 2112.

[0040] Of course, in order for the movable plate 2113 to slide stably along the arc plate 2112, a sliding groove is provided on the arc plate 2112 to allow the movable plate 2113 to slide. When the movable plate 2113 slides, it can fit against the side of the second connecting groove 22 to ensure that the movable plate 2113 and the arc plate 2112 can be used to prevent coal blocks from scattering.

[0041] Please refer to Figure 10 , Figure 11 In one embodiment, the second connecting groove 22 includes a groove body 221 and a lower plate 222, a middle plate 223, and an upper plate 224 installed from bottom to top within the groove body 221; the end of the groove body 221 is hinged to a movable plate 2113; the lower plate 222 overlaps and is flush with the lower plate 212 of the first connecting groove 21, and the lower plate 222 is rotatably connected to the lower plate 212; the middle plate 223 is flush with and abuts the middle plate 213 of the first connecting groove 21, and the middle plate... 223 is rotatably connected to the middle plate 213, and a lower channel 225 is formed between the middle plate 223 and the lower plate 222. The lower channel 225 is connected to the lower channel of the first connecting groove 21. The upper plate 224 overlaps with and is flush with the upper plate 214 of the first connecting groove 21. The upper plate 224 is rotatably connected to the upper plate 214. An upper channel 226 is formed between the upper plate 224 and the groove 221. The upper channel 226 is connected to the upper channel 216 of the first connecting groove 21.

[0042] Specifically, telescopic rods 227 are provided on both sides of the trough 221. One end of the telescopic rod 227 is hinged to the side of the head slot 11, and the other end is hinged to the side of the trough 221. When one side of the telescopic rod 227 extends, the trough 221 can swing to the other side. Considering factors such as the well-working environment, a hydraulic cylinder is used for the selection of the telescopic rods 227. If the telescopic rod 227 on the left side of the trough 221 retracts and the telescopic rod 227 on the right side extends, the trough 221 will tilt to the left; if the telescopic rod 227 on the left side of the trough 221 extends and the telescopic rod 227 on the right side retracts, the trough 221 will tilt to the right. This action allows for adjustment of the angle between the second connecting slot 22 and the first connecting slot 21. Of course, this adjustment action can also be performed continuously, allowing the second connecting slot 22 to swing left and right.

[0043] In one embodiment, the ends of the lower plate 212, middle plate 213, and upper plate 214 away from the head slot 11 are arc-shaped, and the ends of the lower plate 222, middle plate 223, and upper plate 224 facing the head slot 11 are provided with arc-shaped grooves, so that the lower plate 222, middle plate 223, and upper plate 224 can be adapted to rotate with the lower plate 212, middle plate 213, and upper plate 214 respectively. The lower plate 222 has an arc-shaped recess at its end, while the lower plate 212 has an arc-shaped boss that matches the end of the lower plate 222. The boss and the recess engage and fit together, which enables rotation and positioning between the lower plate 222 and the lower plate 212, and also reduces the gap between them to prevent coal blockage. In addition, the same connection method is used for the middle layer plate 223 and the middle plate 213, as well as the upper layer plate 224 and the upper plate 214.

[0044] Specifically, a connecting plate 228 is fixedly installed below the lower plate 222 and the upper plate 224. The connecting plate 228 extends towards the side of the groove 221, and the length of the connecting plate 228 is greater than that of the upper plate 224 and the lower plate 222. At the same time, the ends of the connecting plate 228 are respectively connected to the lower plate 212 and the upper plate 214 by pins. In this way, a double-layer structure can be formed between the upper plate 224 and the upper plate 214, and between the lower plate 222 and the lower plate 212. This ensures the overall structural strength of the area. At the same time, the pins at the ends of the connecting plate 228 and the upper plate 214 and the lower plate 212, as well as the corresponding positioning of the upper plate 224 and the lower plate 222 with the upper plate 214 and the lower plate 212, form rotational positioning at two points. This ensures that the second connecting groove 22 remains stable during the overall left-right swinging motion, thus ensuring the stable operation of the transfer machine and the scraper conveyor.

[0045] In one embodiment, a plurality of through holes 03 are provided on the base plate 12 to connect to the lower chain track 18 of the transfer machine. When the pulverized coal particles on the lower chain track 15 of the scraper conveyor are scraped by the scraper, they can fall into the lower chain track 18 of the transfer machine through the through holes 03.

[0046] Specifically, a protective plate 04 is installed on the middle plate 13. A skylight connecting the lower chain track 15 of the scraper conveyor is opened on both the protective plate 04 and the middle plate 13. The skylight is sealed by two stacked sealing plates 05. Since this is the coal drop point, the skylight design facilitates the inspection and maintenance of the scraper conveyor head chain and sprockets. The double-layered sealing plate 05 design enhances the overall strength of the coal drop point. Of course, for easy replacement and disassembly, both sealing plates 05 are installed using bolts.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
