Problems solved by technology

In order to improve the sampling efficiency, after the sampling is completed, the next point or the next carriage will be sampled immediately. At this time, the relative position of the sampling machine and the train carriage will change, resulting in a change in the position relative to the carriage when it is discharged through the waste belt. When the waste material belt passes through the gap between the two carriages, the waste material will be sprinkled on the train track, which will cause coal samples to accumulate on the track in the long run, causing a complete hidden danger to the train running

Embodiment 1

[0040] like figure 1 As shown, the discarding control method of the sampler of the present embodiment comprises steps:

[0041] S01. During the operation of the sampling machine (such as the train sampling machine) at two adjacent target sampling points, and during the process of discarding the material, detect in real time whether the material discarding port of the sampling machine is located in the compartment between the two adjacent target sampling points gap position;

[0042] S02. When the material discarding port is located at the position of the compartment gap, stop the material discarding operation of the sampling machine.

[0043] The material discarding control method of the sampling machine of the present invention, in the process of checking the vehicle (finding the target sampling point) (carrying out the material discarding operation in this process), detects in real time whether the material discarding port is located between two adjacent target sampling poi...

Embodiment 2

[0059] The difference between this embodiment and the first embodiment is only that the recording point L0 of the initial position of the sampling machine in step S012 is different. specifically,

[0060] Step S01 is specifically:

[0061] S11. After the single sampling and sampling operation of the sampling machine is completed, when the sampling machine starts to travel to the next target sampling point, the waste material operation is started, and the waste material is transported to the carriage through the waste material belt;

[0062] S12. When the output signal of the vehicle inspection laser sensor jumps for the first time, the frame of the current car is detected, and the position value L0 of the sampling machine at this time is recorded through the rotary encoder of the sampling machine;

[0063] S13. The sampling machine continues to travel to the target sampling point. When the sampling machine travels to the position L0+h

Abstract

The invention discloses a material abandoning control method and device for sampling machines, a medium and equipment, belongs to the technical field of sampling, and aims at solving the technical problem that the train running is influenced as the abandoned materials are dispersed at the carriage clearances at present. The adopted technical scheme is that when a sampling machine is operated between two adjacent target sampling points and a material abandoning operation is carried out, real-time detection is carried out to judge whether the material abandoning port of the sampling machine is located at a carriage clearance position between the two adjacent target sampling points or not; and when the material abandoning port is located at the carriage clearance position, the material abandoning operation of the sampling machine is stopped. The adopted technical scheme has the advantages of being simple to operate and improving the train running safety and reliability.

Description

technical field [0001] The invention mainly relates to the technical field of coal sample sampling, in particular to a method, device, medium and equipment for controlling waste of a sampling machine. Background technique [0002] In the coal sampling process, the collection of coal samples is an important link in the mining process. Whether the coal samples are representative or not depends on the collection of coal samples. When manual sampling is often affected by sampling tools and human factors, the representativeness of the collected coal samples is not very strong. Using an automatic mechanized sampling machine instead of manual sampling not only ensures the sampling time, number of sub-samples, and weight of sub-samples, but also ensures The collection of the entire section of the cross-sectional coal flow makes the coal sample representative, and at the same time eliminates the safety hazard of manual sampling, reduces the labor intensity of employees, solves the in...
