DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0017] like Figure 1-Figure 4 As shown, an automatic pushing device for a scraper of a roadheader is disclosed, which is characterized by comprising: refer to Figure 2 As shown, a split tray 1 is divided into slots for placing scrapers by partitions 13, and a transmission device is provided at one end of the split tray 1 and a driven device is provided at the other end; refer to Figure 1 or Figure 4 As shown, a moving bracket 2, one end of which is rotationally connected to the transmission device, and the other end is slidingly connected to the driven device, and the moving bracket 2 is provided with a pushing mechanism for pushing out the scraper.

[0018] like Figure 1 As shown, in the specific implementation process of this embodiment, the transmission device includes a screw 10 that is rotatably arranged between the legs on both sides of one end of the partition tray 1, and a driving motor 11 is provided at one end of the screw 10. The moving bracket 2 is connected to the screw 10 through a screw nut pair, and the driven device includes an optical axis 5 that is arranged between the legs on both sides of the other end of the partition tray. The driving motor 11 rotates to drive the moving bracket 2 to move along the screw 10 and the optical axis 5. It should be noted here that the optical axis 5 is driven, and moves along with the screw 10 when the screw 10 rotates.

[0019] In the specific implementation process of this embodiment, the pushing mechanism includes a bracket body 16 arranged on the moving bracket 2, one end of the bracket body 16 is provided with a stepper motor 4, and the other end is provided with a connecting shaft (not shown in the figure) through a bearing base 3, and a pushing belt 15 is provided between the output end of the stepper motor 4 and the connecting shaft. The pushing belt 15 is provided with a pushing plate 7 for pushing the scraper 9 out, which is specifically explained as follows: the stepper motor 4 rotates, further drives the pushing belt 15 to rotate, and further drives the pushing plate 7 arranged on the pushing belt 15. When the pushing plate 7 rotates to the end of the scraper 9, the scraper 9 is pushed out of the slot by the rotation of the pushing plate 7.

[0020] like Figure 4 As shown, in the specific implementation process of this embodiment, the bearing support 3 is symmetrically fixed at both ends of the moving bracket 2. The symmetrical installation ensures that the rotation path of the push plate 7 is straight, and when pushing the scraper 9, it will not hit the slot, resulting in the scraper being unable to be pushed out.

[0021] During the specific implementation process, this embodiment also includes a controller 6 and a sensor 12. The sensor is connected to the controller and is used to detect the number of pallets in the split tray and transmit data to the controller. The controller transmits instructions to the stepper motor to realize the function of rotating the stepper motor to drive the pulley and belt to push the pallets in sequence.

[0022] In the specific implementation process of this embodiment, a lower baffle 14 is provided at one end of the split tray 1 through a pin 17. Figure 4 As shown, after the split tray 1 and the moving bracket 2 are installed, the latch needs to be opened before the device works, and the lower baffle 14 needs to be moved to allow the scraper 9 to slide out in an orderly manner.

[0023] The stepper motor 4 drives the pulley 8 to provide power to the pulley and the screw 10. The controller 6 is fixed to the moving bracket 2 and moves with the moving bracket 2. The sensor 12 is connected to the controller 6 and is used to detect the number of scrapers 9 in the split tray 1 and transmit data to the controller 6. The controller 6 transmits instructions to the stepper motor 4 to realize the function of the stepper motor 4 rotating to drive the pulley 8 and the push belt 15 to push the scraper 9 in sequence. The automatic pushing device for the scraper of the tunnel boring machine provided by the present invention is used for the assembly of the scraper, which can greatly improve the assembly efficiency.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
