The riffle 7 includes a feed chute 21, a driven roller 22, a riffle steel structure 23, a riffle motor 24, a shaping device 19, a rotary C-type riffling head 25, a spring sweeper 20 and a residue return system 17. The rotary C-type riffling head 25 is connected to a third chute 13. A collector 8 is arranged below the third chute 13. The collector 8 includes a support frame 29 and a collector motor 28. A turntable 27 is arranged on the support frame 29. A sample collecting bottle 26 is arranged on the turntable 27. The turntable 27 is connected to the collector motor 28.

[0022] A slewing mechanism 4 is arranged in the middle of the column 10. The slewing mechanism 4 is connected to the rocker arm 3 to control the rotation angle of the rocker arm 3. A lidar is arranged on the central axis of the slewing mechanism 4 for vehicle positioning. A guardrail 15 is arranged on the steel structure 5. The automatic sampling device for industrial salt is also provided with an electrical control system.

[0023] The head of the spiral drill sampling head 16 is similar to the crushing blade of a shield machine, which can adapt to frozen salt in winter and crystalline salt blocks after absorbing water, and has an excellent crushing effect on large salt blocks.

[0024] The spiral drilling sampling head 16 is made of TA2 material, which greatly improves the anti-salt corrosion performance. There is an overload protection device in its structure, which can greatly extend the service life of the sampling head. The spiral drilling sampling head 16 can reach 400 mm below the salt surface for sampling according to the national standard requirements, or can conduct full-section sampling according to needs. The spiral drilling sampling head 16 is driven with reliable double protection of electricity and machinery, avoiding damage to the unit caused by uncontrollable factors during the vehicle sampling process and affecting the sampling progress. The width of the feed inlet is at least 2.5 - 3 times the maximum particle size of the salt. There is no salt splashing and residual salt during sampling. The sampling method is spiral full-column sampling, meeting the requirements of GB / T8618-2001 standard.

[0025] The feeder 6 adopts a fully enclosed small belt conveyor with a belt width of 500 mm. It has good sealing performance, little loss of material moisture, no dust, and no material accumulation. The motor is steplessly variable speed through a frequency converter, the belt running speed is adjustable, the feeding is uniform, eliminating the salt blockage caused by uneven feeding due to the pulsed feeding of the sampling device. The spring sweeper 20 is installed outside the discharge roller, used to clean the material attached to the working surface of the conveyor belt after discharging.

[0026] The guide chute 21 is provided with a skirt to prevent material leakage during belt feeding. The manual adjustment gate controls the salt layer thickness. The driven roller 22 is waist-shaped. The conveyor is equipped with anti-deviation idlers to prevent the belt from deviating, and the conveyor is equipped with a zero-speed switch to detect the working condition of the feeder 6.

[0027] The splitter 7 is composed of a splitter motor 24, a rotary C-type splitting head 25, and a splitter steel structure 23. The rotary C-type splitting head 25 is made of TA2 material, and its end is equipped with wear-resistant rubber to ensure full-section sampling and not damage the tape. The splitter motor 24 installed on the steel structure 5 drives and stops the rotary C-type splitting head 25. The rotary C-type splitting head 25 continuously discharges materials during rotation, and the proximity switch controls the end point of the splitting head stroke. A protection device is set to prevent the rotary C-type splitting head 25 from misstopping, ensuring the correct stop position of the rotary C-type splitting head 25, eliminating material blockage on the conveyor belt. The minimum number of sub-samples and the splitting time interval are both determined by the tonnage or time number of the sampling vehicle, and the interval time is controlled by the PLC.

[0028] The collector 8 adopts an automatic indexing sample collector. The collector 8 is composed of a sample bottle 26, a turntable 27, a collector motor 28, a proximity switch, and a support frame 29. The collector motor 28 drives the turntable 27 to rotate. The sample bottle 26 is placed on the turntable 27. The end point of the angular displacement of the turntable 27 rotation is controlled by the proximity switch. The sample bottle 26 is provided with a bottle cap to avoid moisture loss. The positioning of the sample bottle 26 of this device is accurate and it is convenient to take the bottle. The storage tank for samples used for total moisture analysis is sealed, and the moisture loss rate shall not exceed 1%.

[0029] In the industrial salt automatic sampling device, mechanisms such as the sampler 1, traveling trolley 2, slewing mechanism 4, sampling head lifting mechanism 14, riffler motor 24, and collector motor 28 adopt independent power distribution systems. At the same time, each mechanism control system is equipped with protection devices for undervoltage, short circuit, overload, and phase loss, and has good short-circuit, overload, and protection functions. Reliable interlock and interlocking functions are installed between the devices of the device, so as to achieve the purpose of automatic control.

[0030] The control system is programmed and controlled by an imported PLC. The system has two modes: on-site manual and remote automatic control. On-site manual is used for debugging, maintenance, and single-machine startup. When the automatic working mode is selected, each device of the industrial salt automatic sampling device can be automatically started and stopped according to the specified program, and samples can be automatically collected and processed; it is also possible to select unlocking, and the operator can selectively start and stop the sampling and sample preparation system according to the actual situation on site.

[0031] The control system has the function of automatically retrieving the working status of the equipment. The system automatically checks whether the equipment is working properly according to the signals of the sensors installed on the equipment, and immediately alarms in case of a fault. After the alarm, the equipment above the fault immediately stops, and the equipment below stops with a time delay according to the program to prevent salt blockage.

[0032] A timer for adjusting the sampling and riffling intervals is provided on the electrical cabinet panel. The setting of the timer can be changed according to different salt types and qualities, so that the PLC automatically adjusts the system operation to ensure that the number of subsamples and sample quality of the sampling meet the relevant standards.

[0033] The electrical control system combines a programmable controller and a manual control machine. It can achieve three working modes: automatic, semi-automatic, and manual.

[0034] Automatic working mode: Place the working mode selection switch on the electrical cabinet control panel in the automatic state, press the system start button once. The sample preparation system automatically starts and stops in sequence. After the startup process is completed, if a vehicle enters the sampling position, press the system start button again. The sampling system automatically positions, automatically samples, then automatically returns to the original position to place the sample, and waits for the next sampling. Press the system start button at any time, the sampling system will return to the original position to discharge materials, and the sample preparation system will automatically stop in sequence after finishing the sample.

[0035] Semi-automatic working mode: Place the working mode selection switch on the electrical cabinet control panel in the semi-automatic state. The difference from the automatic working mode is that the sampling device needs to be manually selected and positioned, and the others are the same as the automatic working mode.

[0036] Manual working mode: Place the working mode selection switch on the electrical cabinet control panel in the manual state, and all equipment needs to be started and stopped with the corresponding operation switches. This mode is used for normal maintenance and repair.

[0037] The working principle of the utility model is as follows: The automatic sampling device is installed on one side of the vehicle driving route, with a vehicle stopper in front. When the vehicle drives to the designated position in front of the vehicle stopper, the swing arm 3, the traveling trolley 2 and the spiral drilling sampling head 16 are in the initial working position (the end close to the column 10). After receiving the vehicle-in-place command, the swing arm 3, the traveling trolley 2 and the spiral drilling sampling head 16 automatically run to the sampling point according to the parameters given by the PLC program based on the random point position command from the computer. The spiral drilling sampling head 16 then automatically drills into the raw salt to take salt samples according to the parameters given by the PLC program based on the random depth position command from the computer below 400 mm. The salt is vertically lifted by the spiral of the spiral drilling sampling head 16 to the position of the sampling head discharge port, leaving a salt sample of more than 5 kg as specified by the national standard. The swing arm 3 and the traveling trolley 2 return to the initial working position and put the salt sample into the salt dropping hopper 18. The salt sample enters the first chute 11 and the second chute 12 through the salt dropping hopper 18. After passing through the two chutes, the salt sample enters the feeder 6 and then enters the splitter 7, where the salt sample is continuously split during rotation. The split salt sample is evenly fed into the shaping device 19, and the salt sample with equal width and height enters the third chute 13. Finally, the salt sample enters the collector 8. The collector 8 automatically runs to the position to receive the salt sample according to the parameters given by the PLC program based on the position of the sample bucket designated by each user from the computer. The remaining salt after splitting is sent to the remaining salt bin through the remaining material return system 17.

[0038] Finally, it should be noted that the above-listed are only the preferred embodiments of the utility model. Of course, those skilled in the art can make changes and modifications to the utility model. If these modifications and variations fall within the scope of the claims of the utility model and its equivalent technologies, they should be considered within the protection scope of the utility model.
