DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] Please see Figures 1 to 7 The present invention provides a combined end head mechanism for connecting a scraper conveyor and a transfer machine, including a scraper conveyor head 01 and a transfer machine tail trough 02; The scraper head 01 includes a head slot 11, and a bottom plate 12, a middle plate 13, and an upper plate 14 installed in sequence from bottom to top in the head slot 11; a scraper lower chainway 15 is formed between the bottom plate 12 and the middle plate 13, and a scraper upper chainway 16 is formed between the upper plate 14 and the head slot 11; a lower vertical plate 17 arranged opposite to each other along the short side direction of the head slot 11 is arranged between the bottom plate 12 and the bottom of the head slot 11, and the lower vertical plate 17 is connected to the bottom plate 12, and A lower chain path 18 of the transfer machine is formed between the bottom of the head trough 11, an upper vertical plate 19 arranged opposite to the short side of the head trough 11 is provided between the middle plate 13 and the upper plate 14, and an upper chain path 20 of the transfer machine is formed between the upper vertical plate 19 and the upper plate 14; a gap is formed on the upper plate 14 for the coal blocks to fall; 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.

[0032] Of course, in order to ensure that the coal flow can be effectively blocked and redirected, a coal plow plate 06 is installed on the head slot 11. This technology is existing technology and its specific structure will not be repeated here.

[0033] Among them, the tail slot 02 of the transfer machine includes a first connecting slot 21 and a second connecting slot 22; the first connecting slot 21 is connected to the head slot 11 and the two are installed in a T shape, so that the first connecting slot 21 can be correspondingly connected to the upper chainway 20 of the transfer machine and the lower chainway 18 of the transfer machine; the second connecting slot 22 is connected to the first connecting slot 21, and the second connecting slot 22 is rotatably connected to the end of the first connecting slot 21 away from the head slot 11, so that the second connecting slot 22 can swing left and right with the end of the first connecting slot 21.

[0034] The second connecting groove 22 is rotatably connected to the first connecting groove 21 to adjust the relative angle between the scraper conveyor and the transfer machine, thereby adjusting the coal flow steering resistance, and at the same time improving the flexibility of the equipment layout of the underground working face. When in use, it can ensure that the coal flow passes smoothly at the junction of the scraper conveyor and the transfer machine, reduce the coal flow steering resistance, and reduce power consumption. Secondly, when the coal flow is congested at the junction of the scraper conveyor and the transfer machine, we can control the second connecting groove 22 so that the second connecting groove 22 forms a continuous left and right swing based on the center line of the first connecting groove 21, and the swing amplitude is between 0-10°; through the left and right swing of the second connecting groove 22, the coal blocks congested at the junction of the scraper conveyor and the transfer machine can be loosened, and the coal blocks can be quickly transported away by relying on the cooperation of the scraper and scraper chain of the transfer machine to achieve smooth coal flow.

[0035] Please see Figure 8 , Fig. 9 In one embodiment, the first connecting groove 21 includes a telescopic protective plate 04211 installed opposite to one side of the head groove 11, and a lower plate 212, a middle plate 213, and an upper plate 214 installed between the telescopic protective plate 04211; the lower plate 212 is connected to the bottom of the head groove 11, the middle plate 213 is connected to the middle plate 13 in the head groove 11, and 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. By means of the telescopic guard plate 04, the coal blocks can be prevented from being scattered, and the coal blocks transported by the scraper conveyor can fall into the chain path 20 on the transfer machine through the gap formed on the upper plate 14.

[0036] To be specific, the telescopic protective plate 04211 includes a fixed seat 2111, a curved plate 2112, and a movable plate 2113; the fixed seat 2111 is installed on one side of the machine head slot 11, the curved plate 2112 is installed on the end of the fixed seat 2111 away from the machine head slot 11, the movable plate 2113 is slidably connected to the curved plate 2112, and one end of the movable plate 2113 is hinged to the second connecting slot 22, when the second connecting slot 22 swings left and right, it can drive the movable plate 2113 to slide and retract along the curved plate 2112.

[0037] Of course, in order to enable the movable plate 2113 to stably slide along the curved plate 2112, a sliding groove is provided on the curved plate 2112 to enable the movable plate 2113 to slide. When the movable plate 2113 slides, the movable plate 2113 can fit with the side of the second connecting groove 22 to ensure that the movable plate 2113 and the curved plate 2112 can be used to prevent the coal blocks from scattering.

[0038] Please see Fig.10 , Fig.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 along the groove body 221; the end of the groove body 221 is hinged to the movable plate 2113, the lower plate 222 overlaps and is flush with the lower plate 212 of the first connecting groove 21, the lower plate 222 is rotatably connected to the lower plate 212, the middle plate 223 is flush with the middle plate 213 of the first connecting groove 21, and the middle plate 223 is rotatably connected to the middle plate 213, a lower channel 225 is formed between the middle plate 223 and the lower plate 222, the lower channel 225 is communicated with the lower channel of the first connecting groove 21, the upper plate 224 is overlapped and 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 body 221, and the upper channel 226 is communicated with the upper channel 216 of the first connecting groove 21.

[0039] Specifically, telescopic rods 227 are provided on both sides of the tank body 221, one end of the telescopic rod 227 is hinged to the side of the head tank 11, and the other end of the telescopic rod 227 is hinged to the side of the tank body 221; when the telescopic rod 227 on one side is extended, the tank body 221 can be swung to the other side. For the selection of the telescopic rod 227, a hydraulic cylinder is used in consideration of factors such as the environment of the well operation. If the telescopic rod 227 on the left side of the tank body 221 is retracted and the telescopic rod 227 on the right side is extended, the tank body 221 is biased to the left; if the telescopic rod 227 on the left side of the tank body 221 is extended and the telescopic rod 227 on the right side is retracted, the tank body 221 is biased to the right. Relying on the above-mentioned action, the angle adjustment of the second connecting slot 22 and the first connecting slot 21 can be achieved. Of course, the above-mentioned adjustment action can also be performed continuously, that is, the left and right swing of the second connecting slot 22 is achieved.

[0040] In one embodiment, the lower plate 212, the middle plate 213, and the upper plate 214 are arc-shaped at one end away from the head slot 11, and the lower plate 222, the middle plate 223, and the upper plate 224 are provided with arc grooves at one end facing the head slot 11, so that the lower plate 222, the middle plate 223, and the upper plate 224 can form an adaptive rotation with the lower plate 212, the middle plate 213, and the upper plate 214. Among them, the end of the lower plate 222 is provided with an arc-shaped concave platform, and the lower plate 212 is provided with an arc-shaped boss platform adapted to the end of the lower plate 222. The boss platform and the concave platform are engaged and fit together, so that the rotation and positioning between the lower plate 222 and the lower plate 212 can be realized, and the gap between the two can be made smaller to prevent the coal blocks from getting stuck. In addition, the middle plate 223 and the middle plate 213, as well as the upper plate 224 and the upper plate 214, are connected in the same manner accordingly.

[0041] To be specific, a connecting plate 228 is fixedly arranged below the lower plate 222 and the upper plate 224, and the connecting plate 228 extends toward one side of the trough body 221, and the length of the connecting plate 228 is greater than 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 pins of the lower plate 212 and the upper plate 214. 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, so as to ensure the overall structural strength here. At the same time, the pin positioning between the end of the connecting plate 228 and the upper plate 214 and the lower plate 212, as well as the positioning formed by the upper plate 224 and the lower plate 222 corresponding to the upper plate 214 and the lower plate 212, can be utilized to form a rotation positioning at two points to ensure that the second connecting groove 22 is still stable during the overall left and right swing, so as to ensure the stable operation of the transfer machine and the scraper conveyor.

[0042] In one embodiment, a plurality of through holes 03 connected to the lower chainway 18 of the transfer machine are provided on the bottom plate 12. When the crushed coal particles on the lower chainway 15 of the scraper conveyor are acted upon by the scraper of the scraper conveyor, the crushed coal particles can fall into the lower chainway 18 of the transfer machine through the through holes 03.

[0043] Specifically, a guard plate 04 is provided on the middle plate 13, and a skylight is provided on the guard plate 04 and the middle plate 13 to connect to the lower chainway 15 of the scraper conveyor. The skylight is sealed by two stacked blocking plates 05. Since this is the coal drop point, the skylight is used to facilitate the inspection and maintenance of the scraper conveyor head chain sprocket; and the design mechanism of the double-layer blocking plate 05 can enhance the overall strength of the coal drop point. Of course, in order to facilitate replacement and disassembly, the two blocking plates 05 are installed by bolt fixing.

[0044] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
