The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0020] Reference will now be made to Figures 1 to 17 A basic chemical raw material sampler provided by the present application comprises a spiral drill bit 100, a sealing cover 200, and a driving mechanism 300. Specifically, the spiral drill bit 100 is provided with a plurality of sampling bins 110 at intervals along its axial direction, and a spiral strip 120 is arranged on the outer circumferential surface of the spiral drill bit 100. When the spiral drill bit 100 is inserted into the basic chemical raw material, the raw material can be discharged along the spiral strip 120, thereby facilitating the smooth insertion of the spiral drill bit 100 into the interior of the basic chemical raw material. The spiral drill bit 100 is also provided with sampling ports 130 in communication with the sampling bins 110 at intervals along its axial direction. The spacing between the plurality of sampling bins 110 and the plurality of sampling ports 130 is set according to actual sampling requirements. The sealing cover 200 is used to open and close the sampling ports 130. The driving mechanism 300 is in transmission connection with the sealing cover 200 and is used to drive the sealing cover 200 to move.

[0021] In use, the auger bit 100 is first inserted into the predetermined depth, and then the sealing cover 200 is driven to move by the driving mechanism 300 until the sealing cover 200 is completely opened to the sampling port 130, so that the corresponding depth of the basic chemical raw materials falls into the corresponding sampling bin 110 through the sampling port 130. After sampling is completed, the sealing cover 200 is driven to move by the driving mechanism 300 until the sealing cover 200 is completely closed to the sampling port 130, and finally the auger bit 100 is extracted.

[0022] In some optional embodiments, as shown in Figure 6 , the driving mechanism 300 drives the sealing cover 200 to rotate in the sampling bin 110, so as to change the position of the sealing cover 200 in the sampling bin 110. Since the sealing cover 200 is located in the sampling bin 110, when the auger bit 100 is inserted into the inside of the accumulated basic chemical raw materials, the opening operation of the sealing cover 200 can be avoided by the material. At the same time, the size of the sealing cover 200 is greater than the size of the sampling port 130, so as to ensure that the sealing cover 200 can completely close the sampling port 130, so as to prevent the basic chemical raw materials from leaking when the sampling is completed, or to prevent the basic chemical raw materials at different heights from entering the same sampling bin 110 and mixing together when the auger bit 100 is inserted.

[0023] In some optional embodiments, as shown in Figure 5 , Figure 6 , Figure 8 and Figure 9 , the driving mechanism 300 includes a first rotating shaft 310 and a first rotary driver 320. Specifically, the first rotating shaft 310 is rotationally arranged in the inside of the auger bit 100, and the center line of the first rotating shaft 310 is parallel to the center line of the auger bit 100, for example, the center line of the first rotating shaft 310 coincides with the center line of the auger bit 100. The sealing cover 200 is sleeved on the first rotating shaft 310, and the first rotary driver 320 is arranged in the inside of the auger bit 100, and the first rotary driver 320 is in transmission connection with the first rotating shaft 310 through the first gear pair 330. Optionally, the first rotary driver 320 can be selected from a rotary motor, a rotary cylinder, a rotary hydraulic cylinder and the like power device. In this embodiment, when the first rotary driver 320 is in a working state, the driving shaft of the first rotary driver 320 transmits power to the first gear pair 330, the first gear pair 330 transmits power to the first rotating shaft 310, so that the first rotating shaft 310 rotates, and the rotation of the first rotating shaft 310 drives the sealing cover 200 to rotate in the sampling bin 110, thereby changing the position of the sealing cover 200 in the sampling bin 110.

[0024] Due to the small particle size of the basic chemical raw material, agglomeration is prone to occur when it is piled up. When the sealing cover 200 is completely opened, the corresponding deep agglomeration of the basic chemical raw material is difficult to fall into the corresponding sampling bin 110 from the sampling port 130, resulting in insufficient sampling sample quantity, and even completely unable to sample, affecting the effectiveness of the sampling operation. Based on this, in some optional embodiments, as shown in Figure 6 The spiral drill bit 100 is provided with a plurality of first sliding cavities 140 and first sliding ports 150 in communication with the first sliding cavities 140 at an axial interval along the same, wherein the number of the first sliding cavities 140 is consistent with the number of the sampling bins 110, each first sliding cavity 140 is located below a corresponding sampling bin 110, and each first sliding port 150 is located below a corresponding sampling port 130.

[0025] The basic chemical raw material sampler further comprises a bulk material device 400 for periodically hitting the agglomerated basic chemical raw material near the sampling port 130 to disperse the agglomerated basic chemical raw material near the sampling port 130, so as to ensure that the agglomerated basic chemical raw material near the sampling port 130 can flow smoothly into the sampling bin 110.

[0026] Specifically, as shown in Figures 10 to 15 The bulk material device 400 comprises a second rotating shaft 410, a sliding block 420, and a hitting block 430. Specifically, the second rotating shaft 410 is rotationally arranged inside the spiral drill bit 100, that is, the second rotating shaft 410 can rotate relative to the whole spiral drill bit 100, and the center line of the second rotating shaft 410 is parallel to the center line of the spiral drill bit 100, for example, the center line of the second rotating shaft 410 coincides with the center line of the spiral drill bit 100, and the second rotating shaft 410 is in transmission connection with the first rotary driver 320 through a second gear pair 440. The sliding block 420 is movably arranged on the second rotating shaft 410. When the first rotary driver 320 is in a working state, the driving shaft of the first rotary driver 320 transmits power to the second gear pair 440, and the second gear pair 440 transmits power to the second rotating shaft 410, so that the second rotating shaft 410 rotates, and the rotation of the second rotating shaft 410 drives the sliding block 420 to move up and down in the first sliding cavity 140. The hitting block 430 is elastically arranged in the first sliding cavity 140. Optionally, a spring 450 can be arranged between the hitting block 430 and the cavity wall of the first sliding cavity 140. The hitting block 430 is in inclined wedge cooperation with the sliding block 420. When the sliding block 420 moves upward in the first sliding cavity 140, the sliding block 420 pushes the hitting block 430 out of the first sliding port 150 in the radial direction, and the spring 450 is stretched. When the sliding block 420 moves downward in the first sliding cavity 140, the hitting block 430 moves reversely under the action of the elastic force generated by the spring 450, and at this time the hitting block 430 is retracted from the first sliding port 150 in the radial direction. Thus, the agglomerated basic chemical raw material near the sampling port 130 is hit and dispersed by the periodic extension and retraction of the hitting block 430.

[0027] In some optional embodiments, as shown in Figure 12 、 Figure 13 The first rotating shaft 310 is hollow, and the second rotating shaft 410 is coaxially arranged in the first rotating shaft 310. Optionally, a bearing can be assembled in the hollow region of the first rotating shaft 310, the outer ring of the bearing is interference-fitted on the first rotating shaft 310, and then the second rotating shaft 410 is arranged on the inner ring of the bearing. In this way, not only the space can be saved, but also a rotating driver can be shared to drive the first rotating shaft 310 and the second rotating shaft 410 to rotate simultaneously. Moreover, the first rotating shaft 310 and the second rotating shaft 410 can be driven to rotate at different speeds by the first gear pair 330 and the second gear pair 440 with different transmission ratios. The first rotating shaft 310 is provided with a sliding groove 311, the sliding block 420 is integrally sleeved on the first rotating shaft 310, and part of the sliding block 420 penetrates the sliding groove 311. The part of the sliding block 420 penetrating the sliding groove 311 is bidirectionally screwed with the second rotating shaft 410. Specifically, a bidirectional threaded groove 411 is arranged on the second rotating shaft 410, and a clamping block matched with the bidirectional threaded groove 411 is arranged on the sliding block 420. The clamping block is embedded in one of the bidirectional threaded grooves 411 at different times. It can be understood that the first rotating driver 320 can drive the first rotating shaft 310 and the second rotating shaft 410 to rotate in the same direction, or drive the first rotating shaft 310 and the second rotating shaft 410 to rotate in different directions.

[0028] In some optional embodiments, as shown in Figure 8 、 Figure 9 The first gear pair 330 includes a driving gear 331 and a first driven gear 332. The driving gear 331 is sleeved on the driving shaft of the first rotating driver 320, and the first driven gear 332 is sleeved on the first rotating shaft 310. The first driven gear 332 is provided with a notch 3321. The second gear pair 440 includes a driving gear 331 and a second driven gear 441. The second driven gear 441 is sleeved on the second rotating shaft 410.

[0029] In the embodiment, when the auger bit 100 is inserted into the piled base chemical raw material, the first rotary driver 320 starts to drive the first rotating shaft 310 and the second rotating shaft 410 to rotate respectively through the first gear pair 330 and the second gear pair 440. Exemplarily, the first rotary driver 320 drives the first rotating shaft 310 and the second rotating shaft 410 to rotate at the same speed in the same direction through the first gear pair 330 and the second gear pair 440. When the driving gear 331 on the driving shaft of the first rotary driver 320 is rotated to the gap 3321 of the first driven gear 332, the driving gear 331 is disengaged from the first driven gear 332, at this time, the sealing cover 200 is completely opened to the sampling port 130, and the first rotating shaft 310 stops rotating, and the sealing cover 200 keeps the position unchanged. Since the driving shaft of the first rotary driver 320 is always rotating, the second rotating shaft 410 keeps rotating, so that the slider 420 reciprocates up and down on the second rotating shaft 410. Conversely, when the sealing cover 200 needs to be closed after sampling, the driving gear 331 and the first driven gear 332 can be re-engaged by applying an external force, and the driving shaft of the first rotary driver 320 is reversely rotated. After the sealing cover 200 is completely closed to the sampling port 130, the driving shaft stops rotating, and finally the auger bit 100 is pulled out.

[0030] In some optional embodiments, as shown in Figure 5 、 Figure 7 、 Figure 8 The auger bit 100 is provided with a reset limiting mechanism 500, which is used to limit the rotation angle of the first rotating shaft 310 and provide a restoring force to prevent the first rotating shaft 310 from rotating from the initial angle to the target angle.

[0031] Specifically, the rotation angle is matched with the number of teeth on the first driven gear 332, and the auger bit 100 is provided with a circular rotating cavity 160, which extends a blocking block 161 inward in the radial direction.

[0032] The reset limiting mechanism 500 includes a rotating block 510 and a torsional spring 520. Specifically, the rotating block 510 is sleeved on the first rotating shaft 310, and the edge of the rotating block 510 is provided with a protrusion 511 which is limitedly matched with the blocking block 161. The torsional spring 520 is sleeved on the first rotating shaft 310, and the two ends of the torsional spring 520 are connected with the rotating block 510 and the cavity wall of the rotating cavity 160 respectively. When the driving gear 331 is disengaged from the first driven gear 332, the rotating block 510 rotates counterclockwise to the position where the blocking block 161 is located in the protrusion 511, and the torsional spring 520 is in the state of being compressed and stored energy. Figure 3C in FIG. 11B, at this time, the rotating block 510 cannot continue to rotate counterclockwise due to the limiting of the protrusion 511 to the block 161, the first rotating shaft 310 stops rotating, although the torsional spring 520 generates a tendency to drive the rotating block 510 to rotate clockwise at this time, but since the rotating direction of the driving gear 331 is also clockwise, the driving gear 331 will offset the elastic force generated by the torsional spring 520, so that the first driven gear 332 remains in a relatively static state; after the sampling is completed, the rotating direction of the driving gear 331 is changed to counterclockwise, so that under the action of the tendency of the torsional spring 520 to drive the rotating block 510 to rotate clockwise, the driving gear 331 and the first driven gear 332 are in meshing state again, and the first driven gear 332 is driven to rotate clockwise at the same time with the driving gear 331 rotating, until the rotating block 510 rotates clockwise to the position where the block 161 is located Figure 3 D in FIG. 11B, at this time, the sealing cover 200 completely closes the sampling port 130 and is in a static state, at the same time, the torsional spring 520 returns to the natural state, and the driving gear 331 still remains in meshing state with the first driven gear 332.

[0033] After the material near the sampling port 130 flows into the sampling bin 110, a vacancy position is left, if the material near the vacancy position collapses and flows to the vacancy position at this time, the material on the upper layer will flow into the sampling port 130 of the lower layer under the action of gravity, and then flow into the sampling bin 110 of the lower layer, causing the sample of the lower sampling layer to be mixed, affecting the accuracy of the detection result of the sampling sample. Based on this, in some optional embodiments, as shown in FIG. 12, the auger bit 100 is provided with a plurality of second sliding ports 170 at intervals along the axial direction, the second sliding port 170 is consistent with the number of the sampling bin 110, and the second sliding port 170 is in communication with the sampling bin 110, each second sliding port 170 is located above a corresponding sampling port 130, and the base chemical raw material sampler further comprises a partition device 600 for blocking the base chemical raw material above the sampling port 130. Figure 6

[0034] Specifically, the partition device 600 comprises a disc 610 and a partition plate 620. Specifically, as shown in FIG. 13, the disc 610 is arranged on the rotating shaft 310, and the partition plate 620 is arranged on the disc 610. Figure 16 Figure 17 ​​As shown, the disc 610 is located in the sampling bin 110 and sleeved on the first rotating shaft 310, the disc 610 is provided with an arc-shaped groove 611, the baffle 620 is slidingly arranged in the second sliding port 170, the baffle 620 is provided with a circular protruding column 621, and the protruding column 621 is slidingly limited in the arc-shaped groove 611 during assembly. When the disc 610 rotates with the first rotating shaft 310, the arc-shaped groove 611 also rotates, thereby periodically generating leftward and rightward pushing forces on the protruding column 621, and when the disc 610 rotates one circle with the first rotating shaft 310, the baffle 620 extends from the second sliding port 170 once and retracts once under the action of the pushing forces. When the driving gear 331 is disengaged from the first driven gear 332, the first rotating shaft 310 does not rotate, and the trend of the arc-shaped groove 611 can make the baffle 620 extend from the second sliding port 170, thereby receiving the material of the current height collapse and placing downward flow.

[0035] In order to facilitate the rotation of the auger bit 100 to extend into the interior of the accumulated basic chemical raw materials, in some optional embodiments, as shown in Figures 1 to 3 As shown, the basic chemical raw material sampler further comprises a handle 700, and the handle 700 is connected with the auger bit 100. In this way, the operator can drive the auger bit 100 to rotate by holding the handle 700 and rotating the handle 700.

[0036] In some optional embodiments, as shown in Figures 1 to 4 As shown, the bottom of the handle 700 is provided with a sleeve interface 710 extending along the axial direction of the auger bit 100, and the auger bit 100 is sleeved in the sleeve interface 710, so that the auger bit 100 can not only rotate in the sleeve interface 710, but also move along the axial direction of the sleeve interface 710. A threaded rod 720 is movably arranged in the handle 700, one end of the threaded rod 720 is connected with the auger bit 100, and a second rotary driver 730 is further arranged in the handle 700, and the second rotary driver 730 is in transmission connection with the threaded rod 720. When the second rotary driver 730 is in a working state, the driving shaft of the second rotary driver 730 transmits power to the threaded rod 720, and the threaded rod 720 moves up and down along the axial direction of the auger bit 100. Optionally, the second rotary driver 730 can be a rotary motor, a rotary cylinder, a rotary hydraulic cylinder or the like. In some optional embodiments, in order to realize the up-and-down movement of the threaded rod 720 along the axial direction of the auger bit 100, as shown in Figures 2 to 4As shown, the handle 700 is provided with a fixed seat 740 and a rotating seat 750, the fixed seat 740 is fixed on the handle 700 and is threadedly connected with the threaded rod 720, and the fixed seat 740 plays a role of limiting the threaded rod 720 in the radial direction. The rotating seat 750 is rotatably arranged on the handle 700, and the rotating seat 750 is sleeved on the threaded rod 720, so that the threaded rod 720 is driven to rotate when the rotating seat 750 rotates. In addition, in order to enable the threaded rod 720 to move up and down, the threaded rod 720 is provided with a first straight edge 721 in the axial direction, and the rotating seat 750 is correspondingly provided with a special-shaped hole 751, the special-shaped hole 751 is provided with a second straight edge 7511 which is matched with the first straight edge 721, and is provided with a threaded edge 7512 which is threadedly connected with the threaded rod 720.
