[0002] The roadbed is the foundation of the road surface. The main function of the roadbed is to provide the necessary conditions for road paving or driving operations. The roadbed needs to withstand the static and dynamic loads of locomotives, vehicles, road surfaces and traffic loads. In order to ensure the reliability and stability of the roadbed, the quality of the roadbed filling materials is generally tested during road construction, such as compaction tests, vibration screening tests, etc. With the continuous development of road construction, different types of roadbed filling material testing machines have appeared on the market.
[0003] The existing roadbed filling material compaction device is mostly composed of a base, a body, a control component and a compaction rod.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0028] The following describes an embodiment of the utility model based on its overall structure.
[0029] A highway roadbed filling material compaction test device, such as Figure 1-5 As shown, it includes a base 1, a body 2 and a control component 3, a compacting rod 4 is fixedly installed at one end of the body 2, and a discharge box 5 is movably installed at one end of the base 1, a placement groove 6 for the discharge box 5 to move is provided on the end surface of the base 1, and a through hole 14 is provided at one end of the discharge box 5, a top block 7 is movably installed inside the base 1, and a first movable groove 8 for the top block 7 to move is provided inside the base 1, a top plate 10 is installed inside the base 1, and a second movable groove 9 for the top plate 10 to move is provided on the end surface of the base 1, and a cap for limiting the discharge box 5 is fixedly installed on the end surface of the base 1. Limiting component, after the discharge box 5 moves to one end of the placement slot 6, the spring 21 applies elastic force to the clamp 15 to fix and limit the discharge box 5. At the same time, the limiting rod 18 enters into the limiting hole 23, and the control component 3 is started to control the compacting rod 4 to compact the raw materials inside the discharge box 5. After compaction is completed, the clamp 15 is released from the restriction of the discharge box 5, and the discharge box 5 is pulled. The worker pushes the top plate 10 to move the position of the top block 7 upward and enters into the discharge box 5 through the through hole 14, and squeezes the extruded filling raw material out of the discharge box 5 to complete the compaction of the roadbed filling material.
[0030] See also Figure 2 - Figure 3The limiting assembly includes a clamp 15, a limiting groove 16, a limiting block 17, a limiting rod 18, a pulling plate 19, a fixing plate 20, a spring 21 and a connecting rod 22. A fixing plate 20 is fixedly installed at one end of the base 1, and a connecting rod 22 is fixedly installed at one end of the fixing plate 20. A clamp 15 is movably installed at one end of the connecting rod 22. A spring 21 is fixedly installed at one end of the fixing plate 20, and the fixing plate 20 and the clamp 15 are connected by a spring 21. The fixing plate 20 provides fixation for the connecting rod 22. The movably installed clamp 15 allows the clamp 15 to move along the connecting rod 22. The spring 21 will continuously provide elastic force to the clamp 15 to ensure that the clamp 15 can clamp and fix the discharge box 5 normally, so as to ensure that the position of the discharge box 5 will not move during the compaction process to affect the compaction effect.
[0031] See also Figure 3 - Figure 5 A limit rod 18 is movably installed inside the clamp 15, and a pull plate 19 is fixedly installed at one end of the limit rod 18. The limit rod 18 and the pull plate 19 are fixedly connected, so that the worker only needs to pull the pull plate 19 to control the position of the limit rod 18, so that the worker can better control the position of the limit rod 18 and complete the restriction and fixation of the clamp 15.
[0032] See also Figure 3 - Figure 5 A limiting block 17 is fixedly installed at one end of the limiting rod 18, and a limiting groove 16 matching the size of the limiting block 17 is opened inside the clamp 15, and a limiting hole 23 matching the limiting rod 18 is opened inside the body 2. The limiting block 17 is restricted by the set limiting groove 16, so that the limiting rod 18 can move inside the clamp 15, and the limiting hole 23 can provide fixation for the limiting rod 18. At the same time, when the limiting rod 18 enters the limiting hole 23, the fixation of the clamp 15 can be guaranteed, thereby improving the accuracy of compaction.
[0033] See also Figure 3 - Figure 4 A slider 12 is fixedly installed at one end of the top plate 10, and a handle 11 is fixedly installed at one end of the top plate 10. A slide groove 13 for the slider 12 to slide is opened inside the base 1. The slider 12 cooperates with the slide groove 13 to fix and limit the top plate 10, and at the same time provide space for the slider 12. The handle 11 can make it more convenient for workers to control the position of the top plate 10, which is more time-saving and labor-saving.
[0034] See also Figure 3 - Figure 4One side end face of the top plate 10 and the bottom end face of the top block 7 are both arc-shaped, and the diameter of the through hole 14 is larger than the diameter of the top block 7. By setting one side end face of the top plate 10 and the bottom end face of the top block 7 to an arc shape, the top plate 10 will not be blocked when in contact with the top block 7, so that the top block 7 is lifted up and enters into the discharge box 5 through the through hole 14, so as to eject the compacted raw materials inside.
[0035] The working principle of the utility model is as follows: when a worker uses the utility model, the worker puts the filling material to be compacted into the discharge box 5, pulls the pull plate 19, so that the limit rod 18 is disengaged from the limit hole 23, and the restriction on the clamp 15 is released. The user pushes the discharge box 5 to move it along the placement slot 6. After it moves a certain distance, the clamp 15 is squeezed to make it move backward. After the discharge box 5 moves to one end of the placement slot 6, the spring 21 applies elastic force to the clamp 15 to fix and restrict the discharge box 5. At the same time, the limit rod 18 enters the limit hole 23, and the control component 3 is started to control the compacting rod 4 to compact the raw materials inside the discharge box 5. After compaction is completed, the restriction of the clamp 15 on the discharge box 5 is released, and the discharge box 5 is pulled. After it moves a certain distance, the worker pushes the top plate 10, so that the top block 7 moves up and enters the discharge box 5 through the through hole 14, and the extruded filling raw material is squeezed out of the discharge box 5 to complete the compaction of the roadbed filling material.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
