Sample collecting device

Abstract

The invention discloses a sample collecting device. The sample colleting device comprises a machine frame; a rotating driving device is fixedly mounted at the bottom of the machine frame; a tray is mounted above the rotating driving device; electricity supply bottom plates are uniformly arranged on the tray; an electricity supply boss is arranged on each electricity supply bottom plate; a conductive sliding ring is suspended right above the rotating centre of the tray; the conductive sliding ring is connected with the electricity supply bosses through wires; a sample barrel is arranged on each electricity supply bottom plate; each sample barrel comprises a barrel body and a barrel cover; an IC (Integrated Circuit) card combination lock is arranged between each barrel body and the corresponding barrel cover; an electricity receiving groove which is coupled with each electricity supply boss is formed in the centre of the bottom of the corresponding barrel body; each IC card combination lock is connected with the corresponding electricity receiving groove through a wire; an IC card sweeping and unlocking device is arranged at the side part of the machine frame; and a sample guide pipe is arranged above the IC card sweeping and unlocking device. According to the sample collecting device, the security performance of equipment can be enhanced; moreover, electricity can be supplied to the IC card combination lock continuously; and long-term use of the equipment is ensured.

Description

technical field [0001] The invention relates to the field of engineering machinery, and more specifically, to a sample collector. Background technique [0002] Coal is a solid combustible organic rock, which is transformed by biochemical action of plant remains, buried and then transformed by geological action. The main elements contained in coal are carbon, hydrogen, oxygen, and nitrogen, accounting for more than 95%, and the remaining elements include sulfur, phosphorus, fluorine, chlorine, and arsenic. When coal is burned, nitrogen does not generate heat, and is transformed into nitrogen oxides and ammonia at high temperatures, which are precipitated in a free state. Sulfur, phosphorus, fluorine, chlorine and arsenic are harmful components in coal, among which sulfur is the most important. When coal is burned, most of the sulfur is oxidized into sulfur dioxide (SO2), which is discharged with flue gas, pollutes the atmosphere, endangers animal and plant growth and human ...

Problems solved by technology

In the conventional sample collector, in order to realize the automatic opening and closing of the sample barrel, the matching ID card and the ID card swiping motor lock are generally set on the sample barrel. The ID card is called an identification card, which is a non-writable sensor. The ID card only uses the "card number", and there is no security function in the card except the card number. The actual "card number" of the ID card is open and exposed, and it is easy for outsiders to open the sample barrel with the card. Therefore, the existing The confidentiality performance of the sample collector is very poor; in addition, in the actual operation process, the sample barrel generally needs to be continuously driven, and the next sample barrel continues to move to the position of the previous sample barrel for loading after the previous sample barrel is filled. Like this, the positions of the sample barrels are different and changeable. Therefore, the power required for the use of the ID card swiping motor lock on the sample collector generally cannot be provided by an external power supply. The existing sample collectors are generally provided by setting batteries on the sample barrel. In this way, every time the sample collector is used for a period of time, the sample barrel must be removed to replace the battery, which greatly limits the long-term use of the sample collector
