[0026] As Figures 1-5 shown, a sampling device for detecting pesticide residues in Chinese medicinal materials proposed by the present utility model comprises:

[0027] The detection cylinder 11 is arranged at the place of use as required. Of course, according to different usage requirements, brackets and the like can be added to support the detection cylinder 11, and the present utility model will not elaborate further on this; a plurality of partition plates 2 are arranged between the inner wall of one end of the detection cylinder 11 and the outer wall of the central cylinder 31, so that a plurality of detection chambers are formed in the detection cylinder 11; as Figure 4 shown, 4 partition plates 2 are arranged between the central cylinder 31 and the detection cylinder 11, and the partition plates 2 are connected to the inner wall of the detection cylinder 11 and the outer wall of the central cylinder 31 by welding, so as to ensure the overall sealing of the formed detection chambers; at the same time, a corrosion-resistant layer needs to be arranged on the inner wall of the detection chambers to avoid the corrosion of the inner wall of the detection chambers by the detection liquid; it should be noted that in the present utility model, the number of the partition plates 2 can be adjusted according to actual situations, and the present utility model will not further limit this.

[0028] The material distribution bin 32 is arranged at the top end of the central cylinder 31; a material distribution plate 41 is arranged in the material distribution bin 32, and the material distribution plate 41 is connected to a first motor 42 arranged outside the material distribution bin 32; and a plurality of material distribution ports 43 corresponding to a plurality of detection bins are arranged on the material distribution bin 32; specifically, the first motor 42 is arranged in the central cylinder 31, and the output shaft of the first motor 42 passes through the bottom plate of the material distribution bin 32 and is connected to the material distribution plate 41 placed in the material distribution bin 32; when the first motor 42 is started, it will drive the material distribution plate 41 to rotate, and the Chinese medicinal materials placed in the material distribution bin 32 will be pushed by the material distribution plate 41 into the material distribution port 43, and after passing through the material distribution port 43, they will enter the specified detection bin; it should be noted that the bottom of the material distribution bin 32 is of a conical structure, and the conical surface is smoothed to reduce the friction with the Chinese medicinal materials directly; during the use stage, the material distribution ports 43 are opened and closed as needed to ensure that the material distribution port 43 corresponding to the specified detection bin is in an open state, and other material distribution ports 43 are in a closed state; only in this way can it be ensured that the Chinese medicinal materials can enter the specified detection bin; the number of the material distribution plates 41 can be set as needed, and they enter the material distribution port 43 in cooperation with the gravity of the Chinese medicinal materials themselves; in the present utility model, it is preferably set to 3 material distribution plates; when the Chinese medicinal materials enter the material distribution bin 32, due to the existence of the conical surface, the Chinese medicinal materials will gradually be placed at the position of the material distribution port 43, and the material distribution plate 41 rotates, and in the present utility model, the rotation speed of the material distribution plate 41 is relatively slow, so that it can push the Chinese medicinal materials to rotate in the material distribution bin 32. When the Chinese medicinal materials rotate to the position of the open material distribution port 43, they will enter the detection bin through the material distribution port 43, and continue to act until all the Chinese medicinal materials in the material distribution bin 32 enter the detection bin.

[0029] As Figure 3 shown, in the present utility model, a plurality of electromagnetic valves 44 are further arranged, and the plurality of electromagnetic valves 44 are arranged on the plurality of material distribution ports 43; in this way, during the material distribution stage, the discharging position of the material distribution bin 32 can be controlled by controlling the opening and closing of the electromagnetic valves 44, so as to ensure that all the Chinese medicinal materials after this pulverization enter the specified detection bin;

[0030] The crushing bin 51 is arranged on the material distribution bin 32, and a bracket is arranged on the inner wall of the detection cylinder 11. The crushing bin 51 is fixed to the detection cylinder 11 through the bracket. At the same time, in the present utility model, a fixing frame can also be arranged outside the detection cylinder 11. The detection cylinder 11 is fixed through the fixing frame, and the fixing frame is arranged at the place of use to support the detection cylinder 11. In addition, the detection cylinder 11 includes two parts, namely an upper part and a lower part. The upper part is connected to the fixing frame, and the detection bin is arranged in the lower part. Through the arrangement of the upper part and the lower part, the crushing bin 51, the material distribution bin 32, and the extraction device 6 can be placed in the upper part, and the detection bin can be placed in the lower part. The upper and lower parts of the detection cylinder 11 can be separated. At the same time, due to the arrangement of the fixing frame, the upper and lower parts can be in a separated state during the use stage. The lower part is directly placed at the place of use, and the upper part is supported by the fixing frame and placed above the lower part. This can prevent the crushing of traditional Chinese medicine in the crushing bin 51 from affecting the detection bin in the lower part and avoid vibration of the detection bin. It should be noted that when the upper and lower parts are in a separated state, before use, the material distribution port 43 in the material distribution bin 32 needs to be aligned with the detection bin to ensure that the crushed traditional Chinese medicine can enter the detection bin.

[0031] A crushing wing 52 is arranged in the crushing bin 51. The crushing wing 52 is connected to the output shaft of a second motor 53 arranged at the top of the detection cylinder 11. The traditional Chinese medicine to be detected enters the crushing bin 51. After the second motor 53 is started, it drives the crushing wing 52 to rotate. The traditional Chinese medicine placed in the crushing bin 51 is crushed by the crushing wing 52. The crushed traditional Chinese medicine will fall into the material distribution bin 32 and be distributed to the designated detection bin in the material distribution bin 32. In addition, to ensure the particle size of the traditional Chinese medicine entering the material distribution bin 32, in the present utility model, a filter plate 54 is preferably arranged. The filter plate 54 is arranged between the crushing bin 51 and the material distribution bin 32. A number of through holes are arranged on the filter plate 54. In this way, the traditional Chinese medicine crushed in the crushing bin 51 will enter the material distribution bin 32 through the number of through holes. The traditional Chinese medicine that cannot enter the material distribution bin 32 will continue to be crushed by the crushing wing in the crushing bin 51 until it is crushed and successfully passes through the filter plate 54.

[0032] The extraction device 6 is arranged on the annular track 7 in the detection cylinder 11. During the use stage, the extraction device 6 can move along the annular track 7. In this way, when sampling is required, the extraction device 6 changes its position on the annular track 7 and moves above the designated detection bin. After the designated detection bin stands still, the extraction device 6 extracts the mixed liquid in the designated detection bin, and the extracted mixed liquid is used for subsequent detection.

[0033] As Figure 1As shown, a top cover 12 is provided at the top of the detection cylinder 11, and the second motor 53 is provided on the top cover 12. Of course, in addition to providing the top cover 12, a mounting bracket can also be provided as needed to mount the second motor 53 through the mounting bracket. Other methods can also be adopted, and the present utility model will not elaborate further on this. In addition, a number of material taking ports 121 are provided on the top cover 12, and the material taking ports 121 are correspondingly arranged with a number of detection bins. Through the arrangement of the material taking ports 121, after the extraction device 6 extracts the mixed liquid, the sampling box 64 can be taken out from the detection bin for subsequent detection. It should be noted that the position where the extraction device 6 stops during detection corresponds to the material taking port 121, so that the sampling box 64 can be taken out through the material taking port 121 after sampling. At the same time, the material taking port 121 is placed between adjacent brackets to avoid affecting the use of the material taking port 121 due to the arrangement of the brackets. Among them, the number of detection bins needs to be set as required. Therefore, the material taking port 121 also increases or decreases according to the number of detection bins to cooperate with the adjustment of the detection bins. The present utility model will not further limit this. A feed inlet 122 is provided on the top cover 12, and the feed inlet 122 is oppositely arranged with the crushing bin 51. During the use stage, Chinese medicinal materials can be put into the crushing bin 51 by opening the top cover 12, or a feed inlet 122 can be provided on the top cover 12, and in this way, Chinese medicinal materials are conveyed into the crushing bin 51 through the feed inlet 122. Of course, when using a conveying mechanism to convey Chinese medicinal materials, the conveying mechanism (such as a conveyor belt) can be arranged adjacent to the feed inlet 122. In this way, the conveyed Chinese medicinal materials will fall to the position of the feed inlet 122 after leaving the conveying mechanism, and enter the crushing bin 51 after passing through the feed inlet 122.

[0034] As Figure 4 and Figure 5 shown, the extraction device 6 includes a driving body 61, a bearing plate 62, a sampling box 64, and an extraction mechanism 65. The driving body 61 is arranged on the annular track 7. The bearing plate 62 is arranged on the driving body 61. And a placing plate 63 is provided on the top of the bearing plate 62 and the driving body 61. The sampling box 64 is arranged on the placing plate 63. The extraction mechanism 65 is arranged on the bearing plate 62 and is communicated with the sampling box 64 through a pipeline. During the use stage, the driving body 61 drives the bearing plate 62 to move on the annular track 7, and at the same time drives the sampling box 64 and the extraction mechanism 65 to move simultaneously. After stopping at a position above the specified detection bin, the extraction mechanism 65 operates to make one end of the extraction mechanism 65 below the liquid level of the mixed liquid in the detection bin. And under the action of the sampling box 64, the mixed liquid in the detection bin is extracted. After the extraction is completed, the extraction mechanism 65 resets and waits to be placed above the next detection bin under the drive of the driving body 61. In the present utility model, the driving body 61 is preferably a motor.

[0035] As Figure 4As shown in the figure, the extraction mechanism 65 includes a pusher 651, a slider 652, and an insertion body 653. The pusher 651 is arranged on the bearing plate 62; the slider 652 is arranged on the slideway on the bearing plate 62, connected to the pusher 651, and moves linearly on the slideway driven by the pusher 651; the insertion body 653 is arranged on the slider 652, communicates with the sampling box 64 through a pipeline, and moves simultaneously with the slider 652; when the extraction device 6 is placed above the designated detection chamber, the pusher 651 acts, pushing the slider 652 to move linearly on the slideway, and at the same time driving the insertion body 653 to act through the slider 652, so that one end of the insertion body 653 is inserted below the liquid level of the mixed liquid in the detection chamber; at this time, the sampling box 64 acts, sucking the mixed liquid into the insertion body 653, and transmitting the mixed liquid to the sampling box 64 through the pipeline; and after sampling is completed, the pusher 651 resets, driving the slider 652 to act, and at the same time driving the insertion body 653 to separate from the mixed liquid through the slider 652; it should be noted that in the present utility model, the insertion body 653 is a tubular structure, the end adjacent to the detection chamber is an open structure, and the end far from the detection chamber is a closed structure, so as to ensure that the mixed liquid entering the insertion body 653 will enter the pipeline.

[0036] In the present utility model, the sampling box 64 includes a box body and an extraction pump (not shown in the figure) arranged on the box body. The extraction pump communicates with the insertion body 653 through a pipeline; when the insertion body 653 is placed below the liquid level of the mixed liquid, the extraction pump acts, and under the action of the extraction pump, the mixed liquid will enter the sampling box 64 and be stored through the sampling box 64; and after sampling is completed, the sampling box 64 is taken out through the access port 121 for subsequent use.

[0037] It should be further noted that a clamping groove can be provided on the sampling box 64 to be clamped with the clamping block on the placement plate 63, or threads can be provided on both the sampling box 64 and the placement plate 63, and the sampling box 64 is fixed on the placement plate 63 by means of threaded connection, specifically subject to the actual situation, and the present utility model will not be further limited in this regard; of course, the sampling box 64 can be taken out after the extraction pump is separated from the sampling box 64 as needed; or the extraction pump and the sampling box 64 can be taken out together; but the pipeline connecting the extraction pump and the insertion body 653 needs to be removed before taking out.

[0038] In addition, in the present utility model, a controller is also provided. The controller can select a single-chip microcomputer or a PLC control board; the controller is respectively connected to the first motor 42, the second motor 53, the driving body 61, the pusher 651, the solenoid valve 44, and the extraction pump, and controls the actions of each part through the controller as needed; of course, the controller adopts the existing technology, and the present utility model will not be further described in this regard.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
