[0001] The utility model belongs to the technical field of roadbed construction equipment, and in particular relates to a stone crushing device used for stone-filled roadbed construction. Background Art

[0002] During the construction of stone-filled roadbed, large stones need to be broken into small pieces by crushing equipment, and then transported to transport vehicles and transported to the construction area for unloading.

[0003] In the prior art, the Chinese utility model patent document with authorization announcement number CN215197497U discloses a discharge buffer device of a mobile jaw crushing and screening station, which crushes stones by a jaw crusher, and the crushed stones are discharged downward from the bottom of the jaw crusher into a guide plate, and the stones slide along the guide plate onto a conveyor belt, and the crushed stones are transported to a uniform speed vehicle through the conveyor belt; wherein the conveyor belt is fixedly arranged on the top of the mobile chassis, which makes the angle and direction of the conveyor belt fixed and cannot be adjusted according to needs. The height of the output end of the conveyor belt cannot match the height of different buckets, which will cause the output end of the conveyor belt to be too high or too low; when the output end of the conveyor belt is too high, the impact of the material on the bucket when it falls is too large, which can easily cause damage to the bucket; when the output end of the conveyor belt is too low, the material cannot be transported to the bucket.

[0004] Therefore, it is necessary to design a stone crushing device for stone-filled roadbed construction that can adjust the direction and angle of the conveying mechanism as needed, improve the conveying flexibility, and facilitate matching with truck beds of different heights to solve the current technical problems. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the utility model provides a stone crushing device for stone-filled roadbed construction that can adjust the direction and angle of the conveying mechanism as needed, improve conveying flexibility, and facilitate matching with truck beds of different heights.
