And then the sample conveying mechanism driving device (3) is started to operate, a sampling shovel (17) filled with a sample is conveyed out of the plate conveyor along a track vertical to the sampling mechanism track (namely the material conveying direction) and is operated to the upper part of the sample collecting hopper (7), a discharging mechanism push rod (5) on a sampling hanger (19) is under the action of a discharging positioning impact rod (6) on the track to open a discharging lifting rope (18) for controlling the sampling shovel (17) to lift the sampling shovel and discharge the sample into the sample collecting hopper (7), a splitter is arranged in the sample collecting hopper (7), the sample is split and then divided into two paths, one part of the sample enters a sampling box to be tested, and the other part of the sample enters a main flow. After the material sample is unloaded, the sample conveying mechanism collides with a limit switch on the track to stop running and returns to the original middle position, the push rod (5) of the unloading mechanism restores to the original position, the unloading lifting rope (18) of the sampling shovel (17) is controlled to be separated from the push rod (5) of the unloading mechanism, the sampling shovel restores to the original position under the action of a reset spring arranged below the sampling shovel, and a sampling process is completed. Thus, the automatic sampling is carried out according to the set time cycle.
Under the condition that double-bin double-plate type conveyors (A, B conveyors) supply materials alternately, if the A-plate type conveyor runs, the sampling automatic control switch can be turned to A, and the sampler automatically takes off the material samples of the A-plate type conveyor at fixed time, fixed quantity, fixed position and fixed section under the control of a PLC program; when the B platen type conveyor runs and the sampling automatic control switch is turned to the B platen type conveyor, the materials of the B platen type conveyor can be automatically sampled.
Adopt the utility model provides a portable two-way automatic sampler is applicable to the sample that chain slat conveyor carried various loose materials. The sampler has the advantages of less equipment, simple and reasonable structure, and capability of automatically sampling and dividing, so that the sampling is representative and accurate.
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of a mobile bidirectional automatic sampler according to the present invention.
Fig. 2 is a sectional view taken along line a-a of fig. 1.
Referring to fig. 1 and 2, the utility model discloses a by send appearance mechanism operation limit switch (1), send appearance mechanism orbit (2), send appearance mechanism drive arrangement (3), sample and send appearance mechanism meso position limit switch (4), send appearance mechanism limit push rod (5), unload location lance (6), sampling mechanism drive arrangement (9), sampling mechanism orbit (10), sampling mechanism operation limit switch (11), sample shovel (17), unload spare parts such as lifting rope (18) and sample gallows (19) and connect and form. Also shown in fig. 1 and 2 are a sample collecting hopper (7), a bin B (8), a raw material bin A (12), a platen conveyor A (13), a discharge hopper (14), a platen conveyor B (15) and a floor platform (16).
