[0051] The working process of the soil sample drying and crushing device is as follows:

[0052] Release the emergency stop button, start the power switch, and power on the device. Set the initial position for self-check and reset according to the program. Click the operation screen component to store the sample, the electromagnetic door lock 17 opens, and place the material tray on each storage plate of the rack component in turn and enter the sample information. Repeat the operation until the sample is stored. The system determines whether the stored sample is a selected sample based on the status of the tray sensor, and an alarm is output if the number of storage layers is wrong.

[0053] When taking out the sample, select the storage plate position where the sample is to be taken out, the electromagnetic door lock opens, and the system determines whether the sample to be taken out is a selected sample based on the status of the tray sensor. If an error is taken out, an alarm will be output.

[0054] After selecting the drying function, the system determines whether there are samples to be dried on the rack assembly. If there are, the stacking assembly reaches the corresponding layer number according to the location of the sample, the clamp mechanism extends to clamp the tray, the stacking assembly moves to the position of the mobile weighing assembly, and the tray is placed on the rotating tray of the mobile weighing assembly. The weigher weighs the sample and records the weight data of the sample before drying. The mobile weighing assembly moves to the bottom of the microwave drying assembly, the lifting cylinder 36 lifts the lifting box door 32, the lifting box door 32 and the drying box body 51 form a closed cavity, the vacuum pump is started, the closed cavity is evacuated to -97kpa, and the microwave heating starts to heat the sample. The temperature sensor and humidity sensor measure the sample temperature in real time to control the microwave power supply and the output power of the magnetron. The weigher measures the sample weight in real time. When the weight change of the sample is less than 2g within 30S (seconds), it is judged that the sample has been dried. The microwave heating and vacuum pump are turned off in sequence, the normal pressure valve is opened, and the normal atmospheric pressure is restored in the drying box. When the pressure sensor reads 0, the lifting cylinder moves to lower the lift box door, the weighing assembly returns to its original position, and the weight data of the sample after drying is recorded. The stacking assembly clamps the material tray and returns it to the rack assembly.

[0055] After selecting the crushing function, the system determines whether there are dried samples on the rack assembly. If there are, the stacking assembly reaches the corresponding layer according to the selected tray, the clamping mechanism extends to clamp the tray, and the stacking assembly sends the tray to the inlet of the flip tank. The tray clamping mechanism forms a seal between the tray and the flip tank, and the stacking assembly returns to the initial position. The flip tank flips, and the sample in the tray enters the crushing chamber, and the flap door of the discharge bin opens automatically. The crushing cylinder moves according to the set program, crushes the sample and sorts out the stones and roots. After the crushing is completed, the purge mechanism starts to clean the crushing chamber. After crushing, the sample is collected into the collection bucket or transported to the integrated sample preparation equipment through the collection trough and the discharge pipe interface. After the crushing is completed, the flip tank is reset. At this time, the sorted stones and roots enter the tray. The stacking assembly sends the tray to the mobile weighing assembly to weigh and measure the screened stones and roots. When completed, the palletizing assembly places the tray back on the rack assembly and notifies the operator on the screen that the tray can be replaced with a sample.

[0056] The above functions can be executed on a certain layer of the material rack component, or set up a task queue to execute until the soil samples in all the material trays have completed the drying and crushing tasks.
