Description

Technical Field

[0001] The utility model relates to road construction equipment, in particular to an asphalt mixture sampler. Background Art

[0002] When paving asphalt roads, asphalt samples must be taken from each truckload to verify that the asphalt mix meets the standards. Traditional samplers consist of a sampling bucket and a hook. The sampler is first hung from the vehicle's side panel, with the hook attached to the top of the panel. The length of the hook is adjusted based on the amount of asphalt loaded, ensuring that the asphalt bucket is completely covered when the vehicle is filled. The hook is then lifted by a crane and raised to the inspection point. During this lifting process, the sampling bucket is full and the material is at the edge of the opening. This can cause material to spill, affecting the surrounding environment and making it difficult to clean up. Utility Model Content

[0029] Combine Figure 1 shown

[0030] An asphalt mixture sampler comprises a material chamber 1.

[0031] Specifically, the material cavity 1 is used for filling asphalt materials, wherein the material cavity can be in various shapes, such as cylindrical, special-shaped, square, etc. Preferably, a square shape is adopted.

[0032] The material chamber 1 is provided with:

[0033] A column 2 is provided at the side end of the material cavity 1 and is used to support the material cavity 1;

[0034] Specifically, by providing the upright column 2 , the force of the material cavity 1 is transferred to the upright column 2 , thereby supporting the material cavity 1 .

[0035] Specifically, the pillar 2 can be in various shapes such as cylindrical, special-shaped or square pillar. Preferably, a square pillar is adopted.

[0036] The hook portion 3 is provided at the side end of the column 2 and is formed with an open hook slot 17;

[0037] Specifically, by providing the hook portion 3, the hook groove 17 on the hook portion 3 can be hung on the side plate of the charging vehicle, and the fixing method is simple and stable.

[0038] The hook portion 4 is provided on the top of the column 2 and is placed above the hook portion 3 , and forms a hook groove 18 with the hook portion 3 .

[0039] Specifically, a hook portion 4 is provided independently of the hook portion 3 and is disposed on the top of the hook portion 3 , so that the hook on the crane can well hook the hook slot 18 and lift the hopper 1 and the column 2 .

[0040] Specifically, after the hook slot 17 of the utility model is hung on the top of the side panel of the charging truck, due to the use of square columns 2, the back of the columns 2 can be well pressed against the side panel of the charging truck, so that the hopper 1 is placed stably. When the hopper 1 is filled with samples, the hook of the crane passes through the hook slot and lifts, so that the hopper 1 and the column 2 are lifted and separated from the charging truck.

[0041] Combine Figure 2 As shown:

[0042] A bottom cavity 5 is provided at the bottom of the material cavity 1, a column cavity 6 connected to the bottom cavity 5 is provided inside the column 2, a hook cavity 7 connected to the column cavity 6 is provided inside the hook part 4, and a through hole 16 connected to the hook cavity 7 is provided on the top inner wall of the hook part 4.

[0043] Specifically, the bottom cavity 5, the column cavity 6, the hook cavity 7 and the through hole 16 function to provide a space for the internal transmission structure components to move.

[0044] A piston plate 9 that can move up and down is provided inside the material chamber 1, a first connecting rod 10 and a second connecting rod 11 are provided on the bottom chamber 5, a third connecting rod 12 is vertically provided in the column chamber 6, and a top plate 13 is horizontally provided in the hook chamber 7.

[0045] The top and bottom of the first connecting rod 10 are rotationally connected to the piston plate 9 and one end of the second connecting rod 11 respectively, the other end of the second connecting rod 11 is rotationally connected to the bottom of the third connecting rod 12, and the top of the third connecting rod 12 is fixedly connected to one end of the top plate 13.

[0046] A first swivel seat 19 is fixedly provided at the lower end of the piston plate 9, and the first swivel seat 19 is rotatably connected to the top of the first connecting rod 10. Second swivel seats 20 are fixedly provided at both ends of the second connecting rod 11, and the second swivel seats 20 at both ends are rotatably connected to the bottom of the first connecting rod 10 and the bottom of the third connecting rod 12 respectively.

[0047] Specifically, the present invention changes the capacity of the material chamber 1 by moving the piston plate 9 up and down in the material chamber 1. When the piston plate 9 rises, the capacity of the material chamber 1 decreases; when the piston plate 9 falls, the capacity of the material chamber 1 increases; when loading, the piston plate 9 is in the most raised position of the material chamber 1, and the capacity of the material chamber 1 is the smallest. After filling with materials, when the material chamber 1 needs to be lifted out, in order to prevent the full material chamber 1 from leaking and dirtying the ground or other areas, it is necessary to increase the capacity of the material chamber 1 when the material chamber 1 is lifted out, so that the material is lowered and not at the opening edge of the material chamber 1, so that the material chamber 1 will not easily spill everywhere when being lifted, so it is necessary to lower the piston plate 9.

[0048] Specifically, in order to achieve the rise and fall of the piston plate 9 and adjust the capacity of the material chamber 1, a second connecting rod 11 is provided. The second connecting rod 11 serves as a lever, and the rotating shaft 15 serves as the rotating support shaft of the lever, wherein the two ends of the rotating shaft 15 are rotatably connected to the two ends of the inner wall of the bottom chamber 5.

[0049] Specifically, when the second connecting rod 11 rotates counterclockwise, the left end of the second connecting rod 11 drives the first connecting rod 10 to descend, driving the piston plate 9 to descend, and the right end of the second connecting rod 11 rises. At this time, the piston plate 9 is in a descending process and the capacity of the material chamber 1 increases.

[0050] Specifically, in order to provide the rotational force of the second connecting rod 11, the top plate 13 is lifted, which drives the top of the third connecting rod 12 to be lifted, drives the bottom of the third connecting rod 12 to be lifted, and drives the right end of the second connecting rod 11 to rotate counterclockwise.

[0051] Specifically, by providing the first rotating seat 19, the second rotating seat 20 and the third rotating seat 21, the connecting rods rotatably connected thereto can move in a certain arc trajectory during the rising or falling process, adapting to the rotation direction of the second connecting rod 11, making the connection of the components smooth and reasonable.

[0052] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown:

[0053] A pressure block 14 is movably provided on the through hole 16 , and a first spring 22 is fixedly provided between the pressure block 14 and the top wall of the hook cavity 7 .

[0054] The baffle 8 is provided with a second spring 23 , and the top of the second spring 23 is fixedly connected to the piston plate 9 .

[0055] Specifically, the function of the first spring 22 is to keep the pressure block 14 always pressed down in the initial state, at which time the top plate 13 is horizontally located at the bottom of the hook cavity 7. The function of the second spring 23 is to keep the piston plate 9 always lifted up in the initial state, so that the capacity of the material cavity 1 is the minimum in the initial state.

[0056] Specifically, when the hook of the crane passes through the hook slot 18 and then lifts, the pressure block 14 is compressed, driving the top plate 13 to lift up, driving the third connecting rod 12 to rise, driving the second connecting rod 11 to rotate counterclockwise, and driving the piston plate 9 to descend. This process causes the material chamber 1 to be lifted and moved out, and is carried out synchronously with the descent of the piston plate of the material chamber 1. Therefore, when the material chamber 1 is lifted, the capacity of the material chamber 1 is increased synchronously, and the material descends in the material chamber 1. The material is not at the opening edge of the material chamber 1, so it can be well ensured that the material will not spill everywhere at the edge when it is lifted, and will not affect the environment of the ground or other areas.

[0057] Specifically, after the material chamber 1 is filled with material, the second spring 23 can always lift the material without being pressed to the flattest state by the material. The second spring 23 will be pressed to the flattest state only when it cooperates with the downward pulling force of the pressure block 14 and the piston plate 9. The elastic force can be adjusted by simply adjusting the number of the second springs. It is necessary to cooperate with the lifting force of the pressure block 14 to pull the piston and increase the capacity of the material chamber 1.

[0058] The size of the piston plate 9 is smaller than the opening size of the material chamber 1 and forms a piston motion structure with the material chamber 1.

[0059] The bottom of the bottom cavity 5 is open and communicated with the outside.

[0060] Specifically, the bottom cavity 5 is connected to the outside world. When loading, the material will flow through the bottom cavity 5 between the piston plate 9 and the inner wall of the material cavity 1 to a certain extent, and then flow back into the material vehicle, but this outflow is very small, and it is also to ensure that the bottom cavity 3 will not be blocked by the material.

[0061] The baffle 8 is formed along the inner wall of the material cavity 1 and has a ring opening 24 formed thereon. The ring opening 24 is connected to the bottom cavity 5 . The size of the ring opening 24 is smaller than that of the piston plate 9 and limits the piston plate 9 .

[0062] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
