[0028] Example 2

[0029] As shown in the figure, the working principle of the present embodiment is as follows:

[0030] During operation, glyphosate raw material powder is transported from the drying bin 1 to the bin 3 through the conveying auger 2, and then is fed into the packaging bin 7 through the spiral feeder 4 after being buffered in the bin 3. The automatic sampler 6 is installed in the packaging bin 7, and the raw material powder is fed into the ton bag 9 under the action of gravity. During the feeding and packaging process, the automatic sampler 6 synchronously operates to obtain the glyphosate raw material powder and then puts the glyphosate raw material powder into the sampling bag. The weighing device 8 is arranged on the packaging bin 7, and is set to 600kg-1000kg according to the actual setting, and is connected with the running motor 5 matched with the spiral feeder 4, so that when the weighing device 8 reaches the set value, the spiral feeder running motor 5 stops running, and the sampling auger conveying motor 14 in the automatic sampler 6 is delayed for 30-60 seconds compared with the running motor 5.

[0031] The automatic sampler 6 is adopted, and the operation mode is as follows: the spiral feeder running motor 5 starts running, the sleeve rotating motor 10 in the sampling sleeve device 601 and the sampling auger conveying motor 14 in the sampling auger device 602 are synchronously started. After the sleeve rotating motor 10 is started, the sleeve rotating motor 10 is connected with the sampling sleeve 12 through the speed reduction connecting shaft device 11 and starts slow rotation. After the sampling auger conveying motor 14 is started, the sampling auger conveying motor 14 is connected with the sampling auger 15 through the speed reduction connecting shaft device 11' and starts slow running. When the sampling sleeve feeding port 13 and the sampling auger feeding port 16 coincide, the glyphosate raw material powder enters the automatic sampling and conveying stage. The obtained raw material powder is conveyed to the sampling discharge port 17 by the sampling auger 15 and then enters the sampling bag.

[0032] The sampling sleeve 12 rotates one circle to complete the first sampling of a single bag. The sampling frequency can be set according to the example, for example, 1000kg of packaging can be set according to 9 times of sampling frequency. When the weighing device 8 reaches 100kg, 200kg, 300kg, 400kg, 500kg, 600kg, 700kg, 800kg and 900kg, the sampling sleeve feeding port 13 and the sampling auger feeding port 16 coincide, and the time for one circle rotation of the sampling sleeve 12 is set. The sampling amount of each time can be set according to the opening size L1 of the sampling sleeve feeding port 13 and the opening size L2 of the sampling auger feeding port 16 to achieve the balanced sampling degree.
