DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 , the utility model provides a technical solution:

[0022] Embodiment 1: A slag conveying device for high-speed railway trench excavation equipment includes a slag conveying device, which is installed on the excavation equipment 1. The excavation equipment 1 includes an excavation component 3 and an outer mold 2. The slag conveying device includes a conveyor belt 5 and a conveying guide rail 6. A stepped bottom plate 14 is provided at the lower end of the outer mold 2. A rotatably mounted guide assembly is provided on the front end of the stepped bottom plate 14 close to the excavation component 3. The conveyor belt 5 is obliquely installed on the other side of the stepped bottom plate 14. The upper end of the conveyor belt 5 is connected to the conveying guide rail 6. The other end of the conveying guide rail 6 extends to the outside of the trench.

[0023] Working principle: First, the excavation component 3 is used to achieve the purpose of excavating the trench, and the excavated debris is transmitted backward. At this time, under the traction and movement of the excavation equipment 1, the outer mold 2 slides and fits along the inner wall of the excavated trench, and the debris adhering to the inner wall of the trench is scraped off in time and gathered at the front end of the outer mold 2. The conveyor belt 5 is used to transport the debris upward, and the conveying guide rail 6 is used to transport the debris to the outer wall of the trench, so as to avoid the debris from affecting the subsequent injection molding.

[0024] Example 2: On the basis of Example 1, in order to ensure that the debris completely enters the conveyor belt 5 and avoid overflow of the debris, the outer mold 2 is located on the rear side of the excavation component 3, and the lower end of the outer mold 2 is in contact with the inner wall of the groove. The guide component is composed of four groups of rotating arc bars 4 distributed in a circular array, and the rotating arc bars 4 are bent in an S shape. The guide component is rotatably installed through a rotating shaft 13.

[0025] Through the fitting of the outer mold 2, the inner wall of the groove is accurately scraped off, and the rotation of the rotating arc bar 4 allows the slag to be accurately transported to the side of the conveyor belt 5 under the action of the rotating centrifugal force, avoiding the slag from being blocked on the outer mold 2.

[0026] The conveyor belt 5 is installed on the conveyor frame 7, and the conveyor frame 7 is fixed on the step bottom plate 14 through the bracket 8 at the lower end. The upper end of the conveyor frame 7 extends to just above the conveying guide rail 6, and the lower end of the conveyor frame 7 is flush with the front end bottom surface of the step bottom plate 14. The conveyor belt 5 is provided with equally spaced partitions 9, and the height of the partitions 9 is less than the width between adjacent partitions 9. A pair of symmetrically distributed baffles 10 are provided on the inner side of the outer mold 2, and the baffles 10 are vertically fixed to the side walls of the outer mold 2.

[0027] By setting a stepped bottom plate 14, the debris at the front end of the outer mold 2 falls onto the conveyor belt 5. The partition plate 9 is used to limit the position of the debris on the conveyor belt 5 to prevent it from sliding down or falling due to gravity. The baffle 10 is used to block both sides of the outer mold 2 to prevent the debris from overflowing to both sides.

[0028] One side of the guide assembly faces the excavation assembly 3 , and the other side of the guide assembly is provided with a pair of guide inclined plates 11 fixed on a pair of baffles 10 , and a guide groove 12 connected to the conveyor belt 5 is formed between adjacent guide inclined plates 11 .

[0029] By providing the guide inclined plate 11, the debris is gathered in the guide groove 12, and then the debris falls completely on the conveyor belt 5, thereby improving the quality of groove forming and the flatness of its inner wall.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
