[0023] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1:

[0025] In this embodiment, if Figures 1 to 5As shown, a reduction machine for automatic sampling of iron ore includes a casing 1 and a control mechanism and a driving mechanism arranged in the casing 1. The control mechanism and the driving mechanism are both existing technologies. The control mechanism can be controlled by a PLC control system. A feeding mechanism 2 and a reduction mechanism 3 are provided at the upper end of the casing 1. The driving mechanism can be realized by a motor and is mainly used to drive the reduction mechanism 3 to rotate. The feeding mechanism 2 is arranged beside the reduction mechanism 3. The reduction mechanism 3 includes a rotating shaft 31, a tray 32, a support 33 and a reduction assembly 34. The lower end of the rotating shaft 31 is connected to the driving mechanism in a transmission manner. The tray 32 is installed at the upper end of the rotating shaft 31. The tray 32 is used to place samples The container, the lower end of the pillar 33 is fixedly connected to the tray 32, the upper end of the pillar 33 is provided with a mounting platform 35, and a plurality of blocks 36 are provided around the mounting platform 35. The shrinking component 34 is installed on the mounting platform 35, and the shrinking component 34 includes an inner ring 37, an outer ring 38 and a plurality of shrinking funnels 39. The inner ring 37 is provided with a plurality of slots 310, and the plurality of slots 310 correspond to the plurality of blocks 36 one by one and engage with each other. The plurality of shrinking funnels 39 are distributed in a circle between the inner ring 37 and the outer ring 38, and the inner ring 37 and the outer ring 38 are fixedly connected by the shrinking funnel 39. The outer ring 38 is provided with a connecting platform 311, and the connecting platform 311 is provided with a plurality of blocks 36.

[0026] In the present invention, the shrinking component 34 and the mounting truncated table 35 are movably connected by the engagement of the clamping block 36 and the clamping slot 310, so that the shrinking component 34 can be easily replaced. Therefore, when conducting different experiments, if there are different requirements for the number of sample copies, different shrinking components 34 can be replaced, such as Figure 2 There are 12 reducing funnels 39 in the middle reducing component 34, which means that the sample can be divided into 12 portions. If there are different needs, different reducing components 34 can be replaced. The arcs spanned by the reducing funnels 39 in different reducing components 34 are different, which can change the number of reducing funnels 39 and thus change the number of samples after reduction. In addition, a block 36 is also provided on the connecting platform 311 of the outer ring 38 of the reducing component 34, so that a larger reducing component 34 can be installed on the outside of the reducing component 34, and the number of reducing funnels 39 on the outer ring reducing component 34 can also be more. Therefore, the adjustment range of the sample quantity when the present invention is in use can be further expanded.

[0027] The appended Figure 1 and Figure 5A set of parameters is provided in the figure. It can be seen that the number of reduction funnels 39 in the reduction component 34 of the inner circle is 12, and the number of reduction funnels 39 in the reduction component 34 of the outer circle is 20. It can be seen that with each increase in the circle, the number of sample portions that can be divided out by the reduction component 34 is greater. In short, the present invention can not only adjust the number of sample portions after reduction by replacing the reduction component 34 to adapt to different experimental needs, but also add a large circle of reduction components 34 to further increase the setting range of the number of sample portions.

[0028] In order to facilitate the alignment of the container containing the sample with the corresponding reduction funnel 39, a plurality of positioning grooves 4 distributed in a circumference are provided at the lower end of the outer ring 38. The number of positioning grooves 4 corresponds to the number of reduction funnels 39. The position of the corresponding reduction funnel 39 can be known through the position of the positioning groove 4, thereby improving the placement efficiency of the container.

[0029] In order to improve the alignment efficiency of the container and the reduction funnel 39 in the radial direction of the tray 32, a plurality of annular grooves 5 are provided on the tray 32. The annular grooves 5 are arranged correspondingly below the moving path of the reduction funnel 39. A positioning ring line 6 is provided in the middle of each annular groove 5. When placing the container, as long as the positioning ring line 6 passes through the center of the bottom of the container, the alignment of the container and the reduction funnel 39 in the radial direction of the tray 32 can be accurately determined.

[0030] Specifically, the unloading mechanism 2 includes a connecting rod 21, a unloading funnel 22, a vibrating conveying assembly 23 and an adjusting assembly 24. The connecting rod 21 is vertically fixed on the housing 1, the unloading funnel 22 is fixedly arranged at the upper end of the connecting rod 21, the adjusting assembly 24 is installed on the housing 1 and the adjusting assembly 24 is located directly below the unloading funnel 22, and the vibrating conveying assembly 23 is installed at the upper end of the adjusting assembly 24. During operation, a large portion of the sample is poured into the unloading funnel 22, and then the vibrating conveying assembly 23 works to convey the sample falling out of the unloading funnel 22. Among them, the setting of the adjusting assembly 24 is to cooperate with the work of the reduction assembly 34, such as Figure 1 As shown, the end of the vibration conveying component 23 is located on the shrinking component 34 of the inner ring. At this time, the sample can only be shrunk by the shrinking component 34 of the inner ring. When the inner ring is not able to shrink the sample enough, the outer ring needs to be used to shrink the sample (the inner ring does not shrink at this time, and the inner and outer rings cannot shrink at the same time, which will cause uneven sample shrinkage). Then, the adjustment component 24 can be rotated to rotate the end of the vibration conveying component 23 to the top of the shrinking component 34 of the outer ring.

[0031] To facilitate adjustment of the conveying end position of the vibrating conveyor assembly 23, the adjustment assembly 24 includes an adjustment dial 241, which is rotatably mounted on the upper end of the housing 1. The adjustment dial 241 is provided with a rotation slot 242, within which a limiting rod 243 is rotatably connected. The upper end of the housing 1 is provided with a plurality of limiting slots 244 that engage with the limiting rods 243. The limiting slots 244 are distributed circumferentially around the adjustment dial 241. Simply rotate the limiting rod 243 out of the limiting slot 244, rotate the adjustment dial 241, and then lower the limiting rod 243 so that the limiting rod 243 enters another limiting slot 244 to fix the position of the adjustment dial 241. The adjustment assembly 24 is very convenient to use. It should be emphasized that a motor can also be provided under the adjustment dial 241 and controlled by a control mechanism to achieve automatic operation of the adjustment assembly 24.

[0032] Specifically, a handle 7 fixedly connected to the free end of the limiting rod 243 is provided, and the limiting rod 243 can be more conveniently controlled by the handle 7 .

[0033] Specifically, the vibrating conveyor assembly 23 includes a bracket 231, a vibrating conveyor 232, and a feed track 233. The bracket 231 is mounted on the upper end of the adjustment turntable 241, the vibrating conveyor 232 is mounted on the upper end of the bracket 231, and the feed track 233 is mounted on the upper end of the vibrating conveyor 232, with one end of the feed track 233 located directly below the discharge hopper 22. The vibrating conveyor 232 is a conventional technology that can provide vibration so that the sample is evenly conveyed along the feed track 233.

[0034] Specifically, a vibration isolation block 8 is provided between the bracket 231 and the vibrating conveyor 232, and the bracket 231 and the vibrating conveyor 232 are fixedly connected via the vibration isolation block 8. The vibration isolation block 8 is prior art and will not be described in detail here. It can prevent the vibration of the vibrating conveyor 232 from affecting other structures.

[0035] 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, 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.
