[0001] The utility model relates to the technical field of shovel plate parts, and in particular to a shovel plate part which is convenient for collecting materials. Background Art

[0002] A tunnel boring machine is a mechanical device specially used for underground engineering or tunnel construction. The blade of a tunnel boring machine often refers to a device used to cut and move soil, rock or other materials.

[0003] The working method of the existing shovel section of the tunnel boring machine is: by rotating the star wheel on the shovel section, the star wheel collides and crushes the materials entering the shovel section, and at the same time, the materials are transported from the transport trough to the transport device.

[0004] Although this enables the shovel section to crush and transport materials through the star wheel, the following problems still exist: since the slot of the shovel section transport trough lacks a screening structure, some large particles of material may enter the transport trough without being completely crushed. After entering the transport device, the large volume of the particles may cause the transport device to jam, affecting the normal operation of the tunnel boring machine. Utility Model Content

[0005] The utility model provides a shovel plate part which is convenient for collecting materials, solves the problem in the prior art that materials with larger volumes are easy to enter the transport trough and cause the transport device to jam, and improves the practicability of the equipment.

[0006] The technical solution of the utility model is as follows:

[0007] A shovel plate part for collecting materials, comprising a shovel plate body,

[0008] A shovel head portion is provided on the shovel plate body, and a transport groove is provided on the shovel plate body away from the shovel head portion. The shovel plate body is rotatably connected with a first star wheel and a second star wheel, and the side walls on both sides of the transport groove are respectively provided with a first placement cavity and a second placement cavity, and a plurality of first material baffle plates are provided between the first placement cavity and the second placement cavity. A first adjusting structure for adjusting the spacing between the first material baffle plates and keeping the spacing between adjacent first material baffle plates equal is provided in the first placement cavity, and a second adjusting structure for adjusting the spacing between the first material baffle plates and keeping the spacing between adjacent first material baffle plates equal is provided in the second placement cavity. The first adjusting structure is also provided with a first control structure for controlling the first adjusting structure and fixing the position of the first adjusting structure, and the second adjusting structure is also provided with a second control structure for controlling the second adjusting structure and fixing the position of the second adjusting structure.

[0009] Further, the first adjustment structure includes a scissors jack. One end of the scissors jack is rotatably connected to the first placement cavity, and one end of each of the first baffle plates is rotatably connected to the scissors jack. The first adjustment structure and the second adjustment structure have the same structure.

[0010] Further, the first control structure includes a control bolt. A threaded hole is provided at the end of the first placement cavity away from the scissors jack. The control bolt is threadedly connected to the threaded hole. A sliding member is provided at the end of the control bolt. A limiting hole is provided on the side surface of the sliding member. A rotating hole is provided at the end of the limiting hole close to the threaded hole. The control bolt is rotatably connected to the rotating hole. A limiting bolt is provided in the limiting hole. The limiting bolt is fixedly connected to the control bolt. The first control structure and the second control structure have the same structure.

[0011] Further, a sliding rail is also fixed in the first placement cavity. A sliding groove is provided in the sliding rail. The sliding groove has a "冂"-shaped structure. The sliding member is slidably connected to the sliding groove.

[0012] Further, the first star wheel includes a rotating disk. A plurality of crushing blades are fixedly connected to the outer periphery of the rotating disk through threaded connection.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] The working process of this embodiment: The material to be crushed and transported enters the shovel plate body through the shoveling material notch. Driven by the rotation of the first star wheel and the second star wheel, the material is crushed and transported to the transport groove. At this time, some fine particles enter the transport device through the gaps between the first baffle plates. Some large-particle materials are blocked by the gaps between the first baffle plates and cannot directly enter the transport device. They can only be crushed again under the drive of the first star wheel and the second star wheel until they can enter the transport groove.

[0017] The utility model sets a plurality of first material baffles on the shovel plate body, and adjusts the gaps between the fixed first material baffles through the first control structure, the second control structure, the first adjustment structure and the second adjustment structure, so as to screen materials of appropriate size to enter the transport device.

The shovel head 13 in this embodiment is arranged on the shovel board body 1, and the transportation trough 14 is arranged on the side of the shovel board body 1 away from the shovel head 13, which is used to install a transportation device to facilitate the transportation of materials processed by the shovel board. The first star wheel 21 and the second star wheel 22 are both rotatably arranged on the shovel board body 1, the first placement cavity 61 and the second placement cavity 62 are respectively arranged on the side walls on both sides of the transportation trough 14, and a plurality of first baffle plates 3 are arranged between the first placement cavity 61 and the second placement cavity 62. The first adjustment structure is arranged in the first placement cavity 61, which is used to adjust the spacing between the first baffle plates 3 and keep the spacing between adjacent first baffle plates 3 equal. The second adjustment structure is arranged in the second placement cavity 62, which is used to adjust the spacing between the first baffle plates 3 and keep the spacing between adjacent first baffle plates 3 equal. The first control structure is arranged on the first adjustment structure, which is used to control the first adjustment structure and fix the position of the first adjustment structure. The second control structure is arranged on the second adjustment structure, which is used to control the second adjustment structure and fix the position of the second adjustment structure.

[0028] The limit baffle 11 in this embodiment is fixedly arranged on the outer periphery of the shovel plate body 1, and the limit baffle 11 is an annular structure. The shovel material notch 12 is arranged on the side of the limit baffle 11 close to the shovel head 13. The limit baffle 11 in this embodiment is designed to prevent the material from being thrown off the shovel material body during the rotation of the first star wheel 21 and the second star wheel 22. The shovel material notch 12 is designed to make it easier for the material to enter the shovel material body.

[0029] The first star wheel 21 in this embodiment includes a rotating disk 211, a plurality of crushing blades 212 are fixedly arranged on the outer periphery of the rotating disk 211 by screw threads, an anti-collision layer 213 is fixedly arranged on the crushing blades 212, and the anti-collision layer 213 is made of rubber material. The first star wheel 21 has the same structure as the second star wheel 22. Such a design is to ensure the strength of the crushing blades 212 and prevent the crushing blades 212 from being broken or damaged.

[0030] In this embodiment, the second baffle plate 41 is arranged at the end of the notch of the transport trough 14 away from the control bolt 5, and the third baffle plate 42 is arranged at the end of the notch of the transport trough 14 close to the control bolt 5. One end of the second baffle plate 41 abuts against the first baffle plate 3, and the other end of the second baffle plate 41 is fixedly connected to the transport trough 14. The vertical projection surface of the third baffle plate 42 partially falls within the vertical projection surface of the first baffle plate 3 on the other side. The second baffle plate 41 is designed to allow large particles on the first baffle plate 3 to slide out of the second baffle plate 41. The third baffle plate 42 is designed to prevent large particles from entering the transport device.

[0031] The first adjustment structure in this embodiment includes a scissors fork 7. One end of the scissors fork 7 is rotatably connected to the first placement cavity 61, and one end of each first baffle plate 3 is rotatably connected to the scissors fork 7. The first adjustment structure and the second adjustment structure have the same structure.

The first control structure and the second control structure have the same structure. Such a design not only ensures that the distance between the first baffle plates can be adjusted by rotating the control bolt 5, but also enables self-locking after the adjustment of the distance between the first baffle plates is completed, avoiding the expansion or reduction of the distance between the first baffle plates during the working process. In this embodiment, when rotating, the control bolt 5 of the first control structure and the control bolt 5 of the second control structure can be rotated simultaneously to control the movement of both ends of the first baffle plate 3, so that the movement of the first baffle plate 3 is not prone to deviation.

[0033] The sliding rail 8 in this embodiment is fixedly arranged in the first placement cavity 61. A sliding groove 81 is arranged in the sliding rail 8. The sliding groove 81 is of a "冂" - shaped structure. The sliding member 9 is slidably connected to the sliding groove 81. Such a design ensures that the sliding member 9 slides more stably in the sliding groove 81 and does not deviate during sliding.

[0034] The working process of this embodiment: The materials to be broken and transported enter the shoveling body through the shoveling notch 12. Driven by the rotation of the first star wheel 21 and the second star wheel 22, the materials are broken and transported to the transport trough 14. At this time, some fine particles enter the transport device through the gaps between the first baffle plates 3. At this time, some large - particle materials are blocked by the gaps between the first baffle plates 3 and cannot directly enter the transport device, and can only be re - broken under the drive of the first star wheel 21 and the second star wheel 22 until they can enter the transport trough 14.
