[0002] Slag, as a common building material, is often used in scenarios such as road paving and dam construction. When used in combination with concrete, it can quickly form the basic structure of components and projects.

[0003] During the construction of a reservoir dam, it is usually necessary to dump a large amount of slag at the dam construction site. At present, the transportation and dumping of slag are mostly carried out by dump trucks. The dump truck is fully loaded with slag, reverses to the edge of the dam construction, raises the dump bucket and dumps the slag downward. There are some functional deficiencies in actual use, and there is room for improvement. For example, the dump truck itself has a large weight, and when it is fully loaded with slag and reverses to the edge of the dam construction, the strength of the dam construction edge position itself has not reached the highest state, and the operation risk itself is relatively large. In addition, when unloading, the dump truck mostly dumps from a fixed position, and the dumped slag forms a conical slag pile at the bottom of the dam, which requires an excavator for subsequent leveling, which is more troublesome, and does not have the function of extending the distance to adjust the unloading position.

[0004] Now, a new type of slag transport device for reservoir dam construction is proposed to solve the above problems. Utility Model Content

A gear disc 9 is fixedly connected to the output end of the servo motor 8, and a transmission chain 6 is sleeved on the outside of the gear ring 5 and the gear disc 9;

[0027] The vertical center lines of the chassis 1, the bearing seat 2, the main shaft 3, and the conveyor belt support bracket 14 coincide with each other, the bottom end of the main shaft 3 is movably connected to the bottom end of the bearing seat 2, the inner wall of the inner bearing 4 is connected to the outer wall of the main shaft 3, the outer wall of the inner bearing 4 is connected to the inner wall of the bearing seat 2, the tooth blocks of the gear ring 5 and the gear disc 9 are distributed at the same distance, the tooth blocks of the gear ring 5 and the gear disc 9 are matched with the tooth eyes of the transmission chain 6, which prolongs the material discharge distance and improves safety, and at the same time can change the dumping position of the slag;

[0028] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the first electric cylinder 10 retracts downward, and the servo motor 8 on the motor mounting frame 7 drives the toothed disc 9 to rotate. The toothed disc 9 drives the main rotating shaft 3 to rotate through the transmission chain 6 and the gear ring 5. The conveyor belt support bracket 14 on the top of the main rotating shaft 3 also rotates synchronously, and the discharge position of the conveyor belt is changed, forming a plurality of uniform slag piles at the bottom of the dam. The inner bearing 4 in the bearing seat 2 can make the main rotating shaft 3 rotate more smoothly.

[0029] Embodiment 2: Two groups of first electric cylinders 10 are respectively installed at the front and rear ends of the bottom of the chassis 1, and the top of the first electric cylinder 10 is fixedly connected with a positioning protrusion 11, and the bottom end of the conveyor belt support bracket 14 is fixedly connected with two groups of arc-shaped positioning plates 12, and the bottom end of the arc-shaped positioning plate 12 is provided with a plurality of groups of positioning grooves 13, and the shape and size of the positioning protrusion 11 are adapted to the shape and size of the positioning groove 13, and the positioning grooves 13 are arranged at equal intervals, which limit the angle and provide upward support at the same time;

[0030] Specifically, Figure 2 and Figure 3 As shown, when the servo motor 8 stops moving, the first electric cylinder 10 extends upward, pushing the positioning protrusion 11 to move upward, and the positioning protrusion 11 is inserted into the positioning groove 13 at the bottom of the arc-shaped positioning plate 12, which limits the rotation direction while providing an upward supporting force to keep the conveyor belt support bracket 14 stable.

The inner bearing 4 in the bearing seat 2 can make the main rotating shaft 3 rotate more smoothly. As the direction of the conveyor belt support bracket 14 is changed and the servo motor 8 stops moving, the first electric cylinder 10 extends upward, pushing the positioning protrusion 11 to move upward, and the positioning protrusion 11 is stuck in the positioning groove 13 at the bottom of the arc-shaped positioning plate 12, limiting the rotation direction while providing an upward support force to keep the conveyor belt support bracket 14 stable.
