The bottleneck of equipment structure needs to be broken through. It is necessary to develop a transfer equipment suitable for the open-pit coal mine environment, and a hydraulic telescopic tail of an open-pit heavy-duty scraper feeder is an important component of it. Summary of the invention

[0003] The purpose of the utility model is to solve the transfer problem between open-pit mine trucks and long-distance belt conveyors, and to develop a transfer feeding device suitable for open-pit coal mine environments, wherein a hydraulic telescopic tail of an open-pit mine heavy-duty scraper feeder is an important component.

[0004] The technical scheme of the utility model is composed of a wing plate 1, a fixed middle plate 2, a fixed side plate 3, a fixed guard plate 4, a fixed bottom plate 5, a flange 6, a left cylinder seat 7, a cylinder pin 8, a cylinder 9, a right cylinder seat 10, a movable middle plate 11, a movable side plate 12, a pin nut 13, an elastic washer A14, an upper bolt 15, a tail wheel assembly pressure block 16, a sliding bottom plate 17, a nut 18, an elastic washer B19, a lower bolt 20, a derailleur bracket 21, an elastic washer C22, a screw 23, a tongue plate cover 24, a derailleur 25, a positioning pin 26, a scraper 27, a locking nut 28, a U-bolt 29, a guide rail 30, a round link chain 31, and a sprocket assembly 32. Figure 7 , 8 As shown in , 9, the fixed bottom plate 5 is the basis, and the wing plate 1, the fixed middle plate 2, the fixed side plate 3, the fixed guard plate 4, and the left cylinder seat 7 are welded together; the guide rail 30 is connected to the fixed bottom plate 5 through the nut 18, the elastic washer B19, and the lower bolt 20; the above parts constitute the fixed seat. Fig.10 , 11 As shown in 12, the moving middle plate 11, the moving side plate 12, the sliding bottom plate 17, the derailleur bracket 21, and the right oil cylinder seat 10 are welded together; the tail wheel assembly pressing block 16 is connected to the moving side plate 12 through the pin nut 13, the elastic washer 14, and the upper bolt 15; the derailleur 25 is placed in the groove A of the derailleur bracket 21; the tongue plate cover 24 is placed above the derailleur bracket 21 and fixed by the elastic washer C22 and the screw 23; the above parts constitute the moving seat. Fig.15 As shown, the scraper 27 and the round link chain 31 are connected together by U-bolts 29 and fixed and locked by anti-loosening nuts 28 to form a scraper chain. Figure 3As shown, the movable seat slides into the fixed seat along the arrow K, and the sliding base plate 17 is inserted into the space formed by the two guide rails 30. Fig. 9 EE view, Fig.12 DD view, assembly effect see Fig.13 ; After the moving seat moves to the position along the arrow K, Figure 6 As shown, the fixed middle plate 2 and the movable middle plate 11 are aligned seamlessly, corresponding to Figure 1 The piston rod of the oil cylinder 9 is in the initial position, and the initial distance between the oil cylinder pins 8 is E. Fig.10 , 11 As shown in FIGS. 12 and 16, the sprocket assembly 32 is placed in the circle between the moving side plate 12 and the tail wheel assembly pressure block 16, the positioning pin 26 is positioned, the column pin nut 13, the elastic washer A14, and the upper bolt 15 are connected and fixed, and the two chain derailleurs 25 are respectively placed in the middle groove of the sprocket of the sprocket assembly 32, which plays the role of separating and supporting the round chain 31. After the sprocket assembly 32 is installed, the shaft does not move, the sprocket is driven, and can rotate freely, that is, the idler. Figure 3 The scraper chain is wound around the wheel of the sprocket assembly 32, the lower round chain runs to the left, winds around the sprocket, and then becomes the upper round chain, changing direction to run to the right. The cylinder body of the oil cylinder 9 is fixed to the left oil cylinder seat 7 with the oil cylinder pin 8, and the piston rod of the oil cylinder 9 is fixed to the right oil cylinder seat 10 with the oil cylinder pin 8. During operation, if the round chain 31 is loose, according to Figure 1 As shown, the piston rod of the oil cylinder 9 pushes the right oil cylinder seat 10 to the right along the arrow J, driving the entire moving seat and the sprocket assembly 32 and the scraper chain assembled on it to move to the right together, playing the role of tensioning the round link chain 31; Figure 2 As shown, when the distance between the two cylinder pins 8 is F, it is the maximum tensioning stroke position of the piston rod of the cylinder 9.

[0005] Furthermore, if Figure 3 , 5 As shown in 6, the upper chain path where the fixed middle plate 2 and the movable middle plate 11 overlap is straight, and the scraper chain passes straightly with little resistance; when the piston rod of the oil cylinder 9 is extended to tighten the round link chain 31, the gap formed between the fixed middle plate 2 and the movable middle plate 11 is V-shaped, and the scraper 27 passes smoothly and horizontally above the gap to avoid the scraping phenomenon; the space formed between the lower part of the fixed middle plate 2 and the movable middle plate 11 and the upper part of the fixed bottom plate 5 is relatively large, which provides a relatively large environmental space for observing the operation of the lower chain path and the maintenance of the scraper chain; as shown in FIG. Fig.14 The wing plate 1 limits the running state of the scraper 27, ensuring that the scraper 27 smoothly transitions to other equipment connected to the flange 6; Figure 3 As shown, the H surface of the fixed side plate 3 is inserted into the K surface of the movable side plate 12, which plays a guiding and positioning role. At the same time, it strengthens the sliding connection strength and rigidity between the fixed seat and the movable seat.
