[0013] In order to more fully explain the implementation of the utility model, the implementation examples of the utility model are provided. These implementation examples are only the elaboration of the utility model and do not limit the scope of the utility model.

[0014] The utility model is further explained in detail in combination with the drawings, and the various marks in the drawings are as follows: 1: groove body; 2: chain; 3: scraper; 4: track plate; 5: discharge port; 6: support; 7: shaft pipe; 8: scraper connecting rod; 9: rotating sleeve; 10: shaft sleeve; 11: driving sprocket; 12: passive sprocket; 13: track groove; 14: motor; 15: sliding block; 16: slide rail; 17: screw rod; 18: tensioning plate; 19: nut; 20: rotating shaft.

[0015] As shown in the drawings, a single-arm buried chain type scraper machine comprises a groove body 1, in the drawings, the side plate and the top plate of the groove body 1 are removed for the convenience of illustration, the feeding port is located on the upper end face of the groove body, Figure 1The feeding port is not shown in the figure, and the discharging port 5 is located on the lower end surface of the groove body. A driving sprocket 11 and a driven sprocket 12 are rotatably installed in the groove body. The driving sprocket 11 is driven by a motor 14. A chain 2 is wound around the driving sprocket and the driven sprocket. The chain has a gap with the bottom surface of the groove body. In this embodiment, the driven sprocket 12 is rotatably installed on a sliding block 15 which is slidingly fitted on a sliding rail 16. A screw rod 17 is fixedly connected to the sliding block. The screw rod passes through a hole in a tensioning plate 18 and is rotatably connected to a nut 19 at the rear end. The nut abuts against the tensioning plate 18. The tensioning plate is fixedly connected to the outside of the groove body. The tightness of the chain can be adjusted by rotating the nut. In this application, there is only one chain, i.e. a single chain.

[0016] The scraper 3 is installed on the chain 2. The driving sprocket and the driven sprocket are installed in the groove body near one side. A track plate 4 is fixedly installed on the inner side of the driving sprocket and the driven sprocket. The track plate has a chain track groove 13. Part of the thickness of the chain is located in the chain track groove 13. A support 6 is fixedly connected to each of the two adjacent chains. The support is located on the thickness of the chain outside the chain track groove. A rotating shaft 20 is rotatably connected to the support. In this embodiment, a shaft tube 7 is fixedly connected to the support. The rotating shaft 20 is rotatably connected in the shaft tube.

[0017] The inner end of the rotating shaft 20 is fixedly connected to a shaft sleeve 10. The scraper connecting rod 8 is slidingly arranged in the two shaft sleeves. The axis of the shaft sleeve is orthogonal to the axis of the rotating shaft in space. The axis of the shaft sleeve and the axis of the rotating shaft are located on two parallel planes in space, or the axis of the shaft sleeve and the axis of the rotating shaft are located on the same plane. A rotating sleeve 9 is rotatably connected to the scraper connecting rod between the two shaft sleeves. The rotating sleeve is limited in the axial direction of the scraper connecting rod. The scraper 3 is fixedly connected to the rotating sleeve.

[0018] The working principle of the scraper machine is as follows: the track plate is connected with the curved groove body; the driving sprocket is assembled at the head of the curved groove body; the driven sprocket is assembled with the tensioning assembly at the tail of the curved groove body; the single-sided wheel chain passes through the track groove and is matched with the driving sprocket and the driven sprocket 4 to form an S-shaped ring arrangement; the scraper is rotatably connected with the scraper connecting rod through the rotating sleeve; the rotating shaft and the support are assembled on the two chains of the single-sided wheel chain. The driving sprocket drives the single-sided wheel chain to move along the track groove. When the scraper 3 runs to the bending part of the curved groove body, the rotating shaft 20 rotates to control the swing angle of the scraper connecting rod 89, so that the scraper 3 turns along the track of the track groove. When the scraper 3 runs to the bottom, it automatically flips down, and the material is transported along the curved groove body bottom to the discharging port through the friction between the scraper 6 and the curved groove body bottom.
