Currently, manual sampling is the most common method. This requires operators to take samples at multiple points, which is labor-intensive. With limited manpower, it is very easy to have uneven sampling and inconsistent insertion depth of the sampling probe. In addition, it is difficult to manually control the spacing when sampling minerals on the vehicle, the sampling time is long, and the work efficiency is low. Summary of the Invention

The support is vertically installed at the sampling port in the middle of the mobile gantry corridor, and the pneumatic slide rail is vertically installed in the middle of the support. The sampling probe is installed on the slide base of the pneumatic slide rail. The sampling probe includes a probe rod and a sampling fork. The upper end of the probe rod is connected to the slide base, and the sampling fork is installed on the lower end of the probe rod. The sampling fork is a three-pronged structure composed of round tubes, and the upper end of the three-pronged structure is connected to the same outlet pipe.

[0008] The negative pressure sample collector is placed on the corridor of the mobile gantry frame. The negative pressure sample collector is connected to a sampling hose, and the inlet end of the sampling hose is connected to the outlet pipe at the upper end of the sampling fork.

[0009] Specifically, the support frame has a triangular structure, with a vertical support rod in the middle and a diagonal brace between the rear of the support rod and the gantry corridor.

[0010] Specifically, the sampling component is equipped with a canopy.

[0011] Due to the adoption of the technical solution described above, this utility model has the following advantages:

[0012] The automatic sampling device of this invention has a stable structure, can quickly and accurately complete multi-point sampling, avoids the instability of manual sampling, reduces manual labor intensity, has a high degree of structural fit, and improves sampling efficiency.

Detailed Implementation

[0017] The present invention will be further explained below with reference to the accompanying drawings and embodiments. However, this explanation should not be construed as limiting the scope of protection of the present invention. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Combined with appendix Figure 1-3 The vehicle-mounted automatic mineral powder sampling device shown includes a sampling platform 1, a sampling component 2, and a negative pressure sample collector 3.

[0019] The sampling platform 1 includes a weighbridge 11 and a mobile gantry 12; the mobile gantry 12 is set across the weighbridge 11, and a sampling port 121 is set in the middle of the corridor of the mobile gantry 12 corresponding to the position of the weighbridge 11.

[0020] The sampling assembly 2 includes a bracket 21, a pneumatic slide rail 22, and a sampling probe 23. The bracket 21 is vertically installed at the sampling port 121 in the middle of the corridor of the movable gantry frame 12. The bracket 21 has a triangular structure and a vertical support rod 211 is installed in the middle of the bracket 21. A diagonal brace 212 is installed between the rear side of the support rod 211 and the corridor of the gantry frame. The pneumatic slide rail 22 is installed on the support rod 211, and the sampling probe 23 is installed on the slide seat 221 of the pneumatic slide rail 22. The sampling probe 23 includes a probe rod 231 and a sampling fork 232. The upper end of the probe rod 231 is connected to the slide seat 221, and the sampling fork 232 is installed on the lower end of the probe rod 231. The sampling fork 232 is a three-pronged structure composed of round tubes. The upper end of the three-pronged structure is connected to the same outlet pipe 2321. A canopy 4 is installed above the sampling assembly 2.

[0021] The negative pressure sample collector 3 is placed on the corridor of the mobile gantry frame 12. The negative pressure sample collector 3 is connected to a sampling hose 31. The inlet end of the sampling hose 31 is connected to the outlet pipe 2321 at the upper end of the sampling fork 232.

[0022] The mobile gantry 12, pneumatic slide rail 22, and negative pressure sample collector 3 of this utility model are all controlled by a PLC. During operation, when the vehicle enters the weighbridge 11, the PLC controls the mobile gantry 12 to move to the front of the vehicle. The PLC controls the slide seat 221 of the pneumatic slide rail 22 to drive the sampling probe 23 to descend from the sampling port 121 of the mobile gantry 12. After the sampling fork 232 is inserted into the mineral powder pile of the vehicle, the negative pressure sample collector 3 is activated. Under the action of adsorption force, the mineral powder enters from the lower end of the sampling fork 232 and is sucked into the negative pressure sample collector 3 along the sampling hose 31, completing the sample extraction of the first sampling point. The PLC controls the pneumatic slide rail 22 to return, driving the sampling probe 23 to rise, and then controls the mobile gantry 12 to move sequentially to the middle and rear of the vehicle, completing the sampling of the front, middle, and rear sampling points of the vehicle.
