[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0024] like Figure 1-3 As shown, the utility model provides a reduction device, including a device body and a guide structure, the device body has a three-dimensional annular cavity, the cavity is divided by a rectifying plate 4 to form a plurality of sample-retaining cutting grooves 6 and a sample-storing collecting groove 7, a sample-retaining port 31 and a sample-storing port 32 are provided on the bottom plate 3 of the device body, the sample-retaining port 31 is arranged in a one-to-one correspondence with the sample-retaining cutting groove 6, and the sample-storing port 32 is arranged in a one-to-one correspondence with the sample-storing collecting groove 7; the guide structure includes an inclined guide plate 5, one end of the guide plate 5 is connected to the upper end of the rectifying plate 4, and the other end is connected to the sample-storing port 32.
[0025] Furthermore, a sample retaining bucket is correspondingly arranged below the sample retaining port 31, and a sample storage bucket is correspondingly arranged below the sample storage port 32. The sample retaining port 31 and the sample storage port 32 are through-hole structures, which facilitates sample placement.
[0026] The utility model divides the three-dimensional annular cavity into a plurality of independently arranged sample cutting grooves 6 and sample storage collection grooves 7 by a rectifying plate 4, so as to realize the diversion of coal samples for different purposes. An inclined guide plate 5 is arranged in the sample storage collection groove 7. After the coal sample falls into the sample cutting groove 6, it enters the sample storage bucket through the sample storage port 31. The coal sample falls into the sample storage collection groove 7 and is guided by the guide plate 5, so that the coal sample automatically gathers toward the sample storage port 32 along the guide plate 5, and enters the sample storage bucket through the sample storage port 32, so as to improve the sample preparation efficiency.
[0027] As an optional implementation, Figure 1 , 2 As shown in Figure 3, the device body also includes an outer circular body 1 and an inner circular body 2 arranged on the bottom plate 3. The outer circular body 1 is sleeved on the outside of the inner circular body 2, and a cavity is formed between the outer circular body 1, the bottom plate 3 and the inner circular body 2.
[0028] Furthermore, the outer circular body 1, the bottom plate 3 and the inner circular body 2 are made of stainless steel, and the outer circular body 1, the bottom plate 3 and the inner circular body 2 are connected by welding, so the structural strength is high.
[0029] The specifications of the outer sphere 1, the bottom plate 3, the inner sphere 2, the rectifying plate 4 and the guide plate 5 can be designed according to the use requirements to meet the sampling requirements of coal samples with different particle sizes.
[0030] As an optional implementation, the bottom center of the bottom plate 3 is transmission-connected to the driving structure to drive the device body to rotate, so that the coal sample can fall into the sample cutting groove 6 and the sample collecting groove 7 in sequence.
[0031] As an optional implementation, Figure 1 , 2 As shown, there are four rectifying plates 4, which extend in the radial direction of the cavity to divide the cavity into two sample-retaining cutting grooves 6 and two sample-retaining collecting grooves 7, and the sample-retaining cutting grooves 6 and the sample-retaining collecting grooves 7 are alternately arranged.
[0032] Furthermore, the two sample-retaining cutting grooves 6 are symmetrically arranged, and the two sample-retaining collecting grooves 7 are symmetrically arranged.
[0033] Most of the existing reduction devices are equipped with eight discharge ports, corresponding to eight barrels, which are cumbersome to operate and inconvenient to clean up later. Moreover, due to the large opening size of the barrel, only one barrel can be collected as a sample. However, the utility model divides the cavity into two sample cutting grooves 6 and two sample collection grooves 7 by the rectifying plate 4, which correspond to two sample barrels and two sample storage barrels respectively. The number of barrels is reduced, the cumbersomeness of operation is reduced, and the later cleaning is convenient. Moreover, the sample cutting grooves 6 and the sample collection grooves 7 are alternately arranged, which increases the number of cutting times of the sample, and improves the efficiency and accuracy of sample preparation.
[0034] As an optional implementation, Figure 1 , 2 As shown, the cross-sectional area of the sample collection groove 7 is larger than the cross-sectional area of the sample cutting groove 6 .
[0035] By increasing the number of the sample cutting grooves 6 and reducing the area of the sample cutting grooves 6, the number of cutting times of the sample is increased, and the sample preparation efficiency and accuracy are improved.
[0036] As an optional implementation, Figure 1 , 2 As shown, the included angle of the two rectifying plates 4 forming the sample retaining cutting groove 6 is 17° to 27°, and the included angle of the two rectifying plates 4 forming the sample storing and collecting groove 7 is 152° to 162°.
[0037] Furthermore, the included angle between the two rectifying plates 4 forming the sample-retaining cutting groove 6 is 22.5°, and the included angle between the two rectifying plates 4 forming the sample-retaining collecting groove 7 is 157.5°.
[0038] As an optional implementation, Figure 3 As shown, the upper end of the rectifying plate 4 is lower than the upper ends of the outer cylindrical body 1 and the inner cylindrical body 2 to form an anti-overflow area 8 .
[0039] Furthermore, the distance between the upper end of the rectifying plate 4 and the upper ends of the outer sphere 1 and the inner sphere 2 is 20 mm, which effectively prevents the coal sample from overflowing.
[0040] The existing reduction and division device lacks an anti-overflow structure. During the discharge process of the coal flow, the coal sample is easy to overflow and cause environmental pollution. However, the utility model forms a height difference between the rectifying plate 4 and the cavity to form an anti-overflow area 8, which plays a certain anti-overflow buffering role on the falling of the coal sample, effectively preventing the coal sample from overflowing and protecting the working environment.
[0041] As an optional implementation, Figure 1 As shown, there are two groups of flow guiding structures, which are correspondingly arranged in the sample storage and collection groove 7. The flow guiding structure includes two flow guiding plates 5, which are symmetrically arranged on both sides of the sample storage port 32.
[0042] Furthermore, the sample storage port 32 is located in the middle of the sample storage collection tank 7, and the cross-sectional area of the sample storage port 32 is smaller than the cross-sectional area of the sample storage collection tank 7, so as to facilitate the installation of the inclined guide plate 5. One end of the guide plate 5 is connected to the upper end of the rectifying plate 4, and the other end is connected to the side of the sample storage port 32, providing a guiding effect for the coal sample entering the sample storage collection tank 7, so that the coal sample automatically gathers toward the sample storage port 32 along the guide plate 5, and enters the sample storage barrel through the sample storage port 32, avoiding the accumulation of coal samples, so as to improve the sample preparation efficiency.
