[0027] Please also refer to Figures 1 to 3 , a sampling device for sand and gravel aggregates provided by the utility model is now described. The sampling device for sand and gravel aggregates includes a base 1, a bracket 2, a connecting assembly 3, a first drive assembly 4, a positioning rod 5, a second drive assembly 6, a sampler 7 and a third drive assembly 8. The base 1 is fixed on the ground, and the base 1 has a vertically arranged support column 11. The bracket 2 is fixed on the support column 11. The connecting assembly 3 is rotatably connected to the bracket 2 around a vertical axis. The first drive assembly 4 is used to drive the connecting assembly 3 to rotate.

[0028] The utility model provides a sampling device for sand and gravel aggregates. Compared with the prior art, the initial position of the sampler 7 is located above the vehicle transporting the sand and gravel aggregates. Then, the first drive component 4 drives the connecting component 3 to rotate and the second drive component 6 drives the positioning rod 5 to slide, so that the sampler 7 reaches a suitable sampling position. Then, the third drive component 8 drives the sampler 7 to slide downward, so that the sampler 7 samples the sand and gravel aggregates on the vehicle. Since the inspectors do not need to climb onto the vehicle transporting the sand and gravel aggregates, it can avoid the inspectors climbing onto the vehicle transporting the sand and gravel aggregates to sample the sand and gravel aggregates, which is not only laborious but also has certain safety hazards.
[0029] In this embodiment, the sampling position of the sampler 7 can be changed by the first driving component 4 driving the connecting component 3 to rotate and the second driving component 6 driving the positioning rod 5 to slide, thereby enabling sampling at different positions.
[0030] Sampler 7 can adopt the spiral sampler in the prior art. Spiral sampler is more suitable for the sampling of sand and gravel aggregate. Of course, sampler 7 can also other prior art.
[0031] In some embodiments, see Figure 2 and Figure 3 The bracket 2 has a horizontally arranged first connecting plate 21, and the connecting assembly 3 includes a connecting shaft 31 and a limiting ring 32.

The two limiting rings 32 are respectively fitted with the top and bottom surfaces of the first connecting plate 21. The first connecting plate 21 limits the two limiting rings 32, which can limit the movement of the connecting shaft 31 in the vertical direction, so that the connecting shaft 31 has only the degree of freedom of rotation, thereby realizing the rotational connection between the connecting assembly 3 and the bracket 2.
[0032] In some embodiments, the above-mentioned characteristic connection component 3 can be used as follows Figure 2 and Figure 3 The structure shown. Figure 2 and Figure 3 The connecting assembly 3 further includes a connecting sleeve 33. The connecting sleeve 33 is fixed on the connecting shaft 31. The positioning rod 5 is slidably inserted into the connecting sleeve 33, thereby being inserted into the connecting assembly 3.
[0033] In some embodiments, the above-mentioned characteristic bracket 2 can be used as follows Figure 2 See the structure shown. Figure 2 The bracket 2 also has a second connecting plate 22 located below the first connecting plate 21 and arranged horizontally. The second connecting plate 22 is fixed on the support column 11, and the first driving component 4 is fixed on the second connecting plate 22, thereby setting the first driving component 4 on the bracket 2.

The output shaft of the first drive assembly 4 can drive the connecting shaft 31 to rotate, that is, drive the connecting assembly 3 to rotate. The advantages of a stepper motor are no cumulative error, simple structure, and easy use and maintenance.
[0035] In some embodiments, see Figure 2 and Figure 3 The connecting sleeve 33 has a notch 331, which runs through both ends of the connecting sleeve 33 along the length direction of the positioning rod 5.

The fixed rack 61 is parallel to the positioning rod 5, and the fixed rack 61 slides through the notch 331. The fixed rack 61 is fixedly connected to the positioning rod 5. The driving motor 62 is fixed to the support plate 332. The driving gear 63 is sleeved and fixed on the output shaft of the driving motor 62, and the driving gear 63 is engaged with the fixed rack 61. The driving motor 62 drives the fixed rack 61 to move back and forth in a straight line through the driving gear 63, thereby driving the positioning rod 5 to slide.
[0036] In this embodiment, the fixed rack 61 can increase the strength of the positioning rod 5 , thereby preventing the positioning rod 5 from being deformed.

Since the sampler 7 is fixedly connected to the lifting part 10 and the fixing part 9 is fixedly connected to the positioning rod 5, the sliding connection between the sampler 7 and the positioning rod 5 in the vertical direction is indirectly achieved.
[0038] In some embodiments, see Figure 1 The sampling device for sand and gravel aggregate further comprises a camera 120. The camera 120 is fixed on the lower surface of the fixing member 9. The sampling process is conveniently observed by the camera 120.
[0039] In some embodiments, see Figure 2The third drive assembly 8 is fixed to the fixing member 9 and has a piston rod that can be extended and retracted in the vertical direction. The piston rod of the third drive assembly 8 is fixedly connected to the lifting member 10. The piston rod of the third drive assembly 8 drives the sampler 7 to slide along the sliding shaft 110 in the vertical direction by extending and retracting.
[0040] In this embodiment, the third driving assembly 8 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.
[0041] In some embodiments, see Figure 4 and Figure 5 The sampling equipment for sand and gravel aggregates also includes a fixed shaft 130, a supporting ring 140 and a sample barrel 150. The fixed shaft 130 is arranged horizontally, and one end of the fixed shaft 130 is fixedly connected to the support column 11. The axis of the supporting ring 140 is arranged vertically, and the supporting ring 140 is fixedly connected to the other end of the fixed shaft 130. The sample barrel 150 is slidably inserted into the supporting ring 140, and the top of the sample barrel 150 has an outward folded edge 1501, and the folded edge 1501 abuts against the upper surface of the supporting ring 140. The supporting ring 140 is fixedly connected to the support column 11 through the fixed shaft 130, and the supporting ring 140 supports the sample barrel 150 by supporting the folded edge 1501. After the sampler 7 has completed sampling, the first drive assembly 4 drives the connecting assembly 3 to rotate, and the second drive assembly 6 drives the positioning rod 5 to slide, so that the sampler 7 reaches the appropriate position, allowing the sampler 7 to discharge the sample into the sample barrel 150. The sample barrel 150 is then slid out of the support ring 140 and a new sample barrel 150 is placed in the support ring 140.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
