[0035] like Figure 1 and Figure 3 As shown, the production line 100 further includes a recovery device 160, which includes a weighing mechanism 161, a feeder 162 and a recovery mechanism 163. The weighing mechanism 161 and the feeder 162 are sequentially arranged below the reduction device 130 from top to bottom. The recovery mechanism 163 connects the feeder 162 and the conveying device 110. The recovery mechanism 163 is used to convey the sample at the feeder 162 to the conveying device 110. Another part of the sample after being reduced by the reduction device 130 is conveyed to the recovery device 160, and passes through the weighing mechanism 161, the feeder 162 and the recovery mechanism 163 in sequence, and is finally conveyed to the conveying device 110; the recovery device 160 can recover another part of the sample after being reduced by the reduction device 130, that is, recover the sample that has not been broken, so as to reduce the waste of industrial silicon raw materials and save production costs.
[0036] like Figure 1 and Figure 3As shown, the weighing mechanism 161 includes a first weighing funnel 1611, a sifter 1612 and a plurality of second weighing funnels 1613. The first weighing funnel 1611 is arranged on the top of the sifter 1612 and is used to transport another part of the sample after being reduced by the reduction device 130 to the sifter 1612. Each second weighing funnel 1613 is arranged on the feeder 162 and connected to the bottom of the sifter 1612. The first weighing funnel 1611 and each second weighing funnel 1613 are used to weigh the weight of the sample, and the plurality of second weighing funnels 1613 are respectively used to receive samples of different diameters and particle sizes. The sifter 1612 is used to sieve the samples and transport the samples in different diameter particle size ranges to different second weighing funnels 1613; when the samples pass through the weighing mechanism 161, they first need to enter the first weighing funnel 1611, and the first weighing funnel 1611 weighs the total weight of the samples, then the sifter 1612 sieves the samples and transports the samples in different diameter particle size ranges to different second weighing funnels 1613, and the second weighing funnel 1613 weighs the weight of the samples in a certain diameter particle size range; by comparing the weight of the sample in a certain second weighing funnel 1613 with the mass of the sample in the first weighing funnel 1611, the proportion of the weight of the sample in a certain diameter particle size range to the weight of the total sample can be obtained, and then the proportion of industrial silicon raw materials in a certain diameter particle size range can be obtained.

[0038] For example, in a specific embodiment, the volume of the first weighing funnel 1611 is greater than the volume of the second weighing funnel 1613, and the first weighing funnel 1611 is arranged below the reduction device 130. The first weighing funnel 1611, the sifter 1612, the second weighing funnel 1613 and the feeder 162 are arranged in sequence from top to bottom, so that the sample can be transported from the reduction device 130 to the first weighing funnel 1611, the sifter 1612, the second weighing funnel 1613 and the feeder 162 in sequence under the action of gravity, which can simplify the sample transportation process between the devices, reduce the use of sample transportation structures, and reduce production costs.
[0039] like Figure 1 and Figure 3 As shown, the recovery mechanism 163 includes a conveying track 1631 and a hopper 1632. The conveying track 1631 is arranged on one side of the feeder 162. The hopper 1632 is used to receive the sample conveyed by the feeder 162. The conveying track 1631 can drive the hopper 1632 to move, so as to convey the sample in the hopper 1632 to the conveying device 110. Specifically, the samples weighed by the second weighing funnel 1613 will be conveyed to the feeder 162, and then the feeder 162 will convey the samples to the hopper 1632. Finally, the conveying track 1631 drives the hopper 1632 to move, and the samples are conveyed to the conveying device 110, so as to realize the recovery of the samples.
[0040] like Figure 1 and Figure 3 As shown, there are multiple hoppers 1632, which are spaced apart on the conveying track 1631, and the conveying track 1631 can drive the multiple hoppers 1632 to move. When recovering samples, the conveying track 1631 can drive the multiple hoppers 1632 to move to convey the samples to the conveying device 110, which can improve work efficiency.
[0041] In one embodiment, if Figure 1 and Figure 2 As shown, the sifter 1612 includes a vibrating screen 1615, and the sampling device 120 is arranged at the end of the conveyor belt 111. The vibrating screen 1615 is mainly suitable for separating and filtering various fine materials such as particles, powders, and liquids. In other words, the vibrating screen 1615 is mainly suitable for screening silica in industrial silicon raw materials, and the weight of silica is relatively heavy. The sampling device 120 uses a receiving frame to receive samples at the end of the conveyor belt 111 to achieve sampling of industrial silicon raw materials.
[0042] In another embodiment, if Figure 3 and Figure 4 As shown, the screener 1612 includes a drum screen 1616, and the sampling device 120 is arranged in the middle of the conveyor belt 111. The drum screen 1616 is mainly suitable for separating and screening large particles such as coal, that is, the drum screen 1616 is mainly suitable for screening clean coal and wood chips in industrial silicon raw materials, and the weight of clean coal and wood chips is relatively light. The sampling device 120 uses a cleaning brush to sweep the sample into the receiving frame in the middle of the conveyor belt 111 to achieve sampling of industrial silicon raw materials.
[0043] like Figure 5As shown, the automatic sampling device includes two production lines 100, one of which is used for sampling silica, and the other is used for sampling clean coal and wood chips. The automatic sampling device includes two production lines 100, which are used for sampling silica and clean coal and wood chips respectively, so that when sampling industrial silicon raw materials, silica sampling and clean coal and wood chips can be performed simultaneously to improve work efficiency.
[0044] The process of collecting samples using the automatic sampling equipment is as follows (taking silica sampling as an example): first, the sampling device 120 collects samples at the end of the conveyor belt 111, and then transports them to the reduction device 130 through the conveying pipe 112, and the reduction device 130 reduces the samples (that is, mixes the samples and piles them up); one part of the samples is transported to the crushing device 140, and after crushing, it is transported to the collecting device 150, and the other part of the samples is transported to the first weighing funnel 1611, the vibrating screen 1615, the second weighing funnel 1613 and the feeder 162 in sequence, and finally the recovery mechanism 163 transports the other part of the samples to the conveying device 110 to achieve sample recovery.
[0045] The utility model provides two embodiments, the difference between the two embodiments is that the sifter 1612 is different and the setting position of the collecting device is different; in the first embodiment, Figure 1 and Figure 2 As shown, the sifter 1612 is a vibrating screen 1615, and the sampling device 120 is disposed at the end of the conveyor belt 111; in the second embodiment, as shown in FIG.
