The cover plate 2 is fixed on the top of the stirring box 1 (i.e. the opening side of the stirring box 1) by screw fastening mode. The feeding port 3 is arranged on the top of the cover plate 2, which is convenient to add materials into the stirring box 1 and sample taking (the feeding port 3 is composed of a feeding column and a feeding hole, the feeding column is fixed on the top of the cover plate 2 by welding mode, i.e. the side of the cover plate 2 away from the stirring box 1, the feeding hole vertically penetrates the feeding column and the cover plate 2 and is communicated with the inside of the stirring box 1, which is convenient for material adding and sampling).

[0034] The outer periphery of the feeding column is provided with external threads, and the sealing cover is screwed on the feeding column by thread connection mode. During the process of adding or taking materials, the sealing cover can be unscrewed by reversing the sealing cover. After the process of adding or taking materials is completed, the sealing cover is screwed tightly to avoid the impurities from the outside entering the stirring box 1 through the feeding port 3 (the sealing cover is not shown in the figure, the inner side wall of the sealing cover is provided with internal threads matched with the external threads, and the sealing cover is a common plastic cover on the market, similar to the connection mode of the beverage bottle and the bottle cap).

[0035] The stirring assembly is arranged on the cover plate 2 for stirring materials, and the stirring assembly comprises a support plate 6, a mounting plate 7, a driving motor 8, a first gear 9, a first stirring shaft 10, a first stirring blade 11, a second gear 12, a second stirring shaft 13 and a second stirring blade 14. The support plate 6 has two pieces, which are fixed on the top of the cover plate 2 (i.e. the side of the cover plate 2 away from the stirring box 1) by welding mode. The distance between the two support plates 6 is greater than the diameter of the first gear 9, so as to avoid collision and interference with the rotating track of the first gear 9 during stirring.

[0036] The mounting plate 7 is fixed on the top of the two support plates 6 by welding mode. The mounting plate 7 and the support plate 6 form a "]" shaped structure, and the opening side of the "]" shaped structure faces the cover plate 2, which provides a space for the installation of the first gear 9.

Under the action of the bearing, the first stirring shaft 10 and the second stirring shaft 13 can rotate, thereby completing the mixing and stirring of the materials in the stirring box 1.

[0041] The housing of the drive motor 8 is fixed to the top of the mounting plate 7 by screws. The drive shaft of the drive motor 8 passes through the mounting plate 7 and is connected to the first stirring shaft 10 via a coupling (the coupling is not shown in the figure). The drive motor 8 drives the first stirring shaft 10 to rotate, which in turn drives the second stirring shaft 13 to rotate under the drive of the gear transmission mechanism.

[0042] The discharge platform 4 is fixed to the bottom inner side of the mixing tank 1, and the top of the discharge platform 4 forms an inclined slope to facilitate the discharge of materials from the mixing tank 1. The discharge port 5 is fixed to the bottom outer side of the mixing tank 1 and close to the lowest point of the discharge platform 4. A valve is installed on the discharge port 5. The valve is closed during mixing to prevent the internal materials from flowing out. After mixing, the valve is opened to discharge the materials (the valve is not shown in the figure).

[0043] A sampling assembly is installed on one side of the mixing tank 1 for sampling materials inside the mixing tank 1. The sampling assembly includes a vertical plate 15, an extension plate 16, a support rib 17, a guide sleeve 18, a guide column 19, a lifting plate 20, a lifting cylinder 21, an anti-detachment plate 22, a sampling cylinder 23, a slot 24, a through groove 25, a sampling column 26, a sampling groove 27, a handle 28, a first limiting plate 29, a second limiting plate 30, and a contact plate 31. A horizontally positioned pad is welded to the bottom of the vertical plate 15, and the pad is fixed to the ground by screws, thereby fixing the vertical plate 15.

To prevent the extension plate 16 from deforming under the action of gravity, the support rib 17 is inclined and fixed between the extension plate 16 and the upright plate 15 to improve the structural strength of the extension plate 16.

[0045] The cylinder body of the lifting cylinder 21 is fixed on the top of the extension plate 16 by screw fastening, and the piston rod of the lifting cylinder 21 is connected with the lifting plate 20 by penetrating the extension plate 16. The lifting plate 20 is driven to lift by the lifting cylinder 21, so that the sample at different height layers can be taken during sampling, and the versatility is improved.

When the lifting plate 20 is driven to lift by the lifting cylinder 21, the guide column 19 is simultaneously lifted along the guide sleeve 18. The anti-falling plate 22 is fixed on the top of the guide column 19, and the diameter of the anti-falling plate 22 is greater than that of the guide column 19, so that the guide column 19 is prevented from falling out of the guide sleeve 18 when the lifting plate 20 is driven to descend by the lifting cylinder 21.

[0047] The sampling cylinder 23 is fixed on the lifting plate 20 (specifically, the lifting plate 20 is provided with a through hole, the sampling cylinder 23 is penetrated in the through hole, and then the two are fixed together by welding. When the lifting plate 20 is driven to descend by the lifting cylinder 21, the sampling cylinder 23 is simultaneously driven to descend). The diameter of the sampling cylinder 23 is equal to the inner diameter of the feeding port 3, so that the sampling cylinder 23 can descend along the feeding port 3 and extend into the stirring box 1 to sample the material in the stirring box 1.

[0048] As shown in Figure 4 , 5 , the insertion groove 24 is provided in the sampling cylinder 23, the sampling column 26 has a diameter equal to that of the insertion groove 24, and the sampling column 26 is inserted in the insertion groove 24. The through groove 25 is provided at the bottom of the sampling cylinder 23 and communicates with the insertion groove 24, and the sampling groove 27 is provided at the bottom of the sampling column 26 and cooperates with the through groove 25. After the sampling column 26 is inserted in the insertion groove 24, the sampling column 26 is rotated until the sampling groove 27 and the through groove 25 are coincided, at this time, the material in the stirring box 1 flows into the sampling groove 27 through the through groove 25; the sampling column 26 is continuously rotated until the sampling groove 27 and the through groove 25 are in opposite states, at this time, the through groove 25 can be sealed to prevent the material in the stirring box 1 from flowing into the insertion groove 24 through the through groove 25.

[0049] The handle 28 is fixed on the top of the sampling column 26, the circumferential surface of the handle 28 is provided with anti-skid grooves, and the operator can rotate the sampling column 26 without slipping. The first limiting plate 29 and the second limiting plate 30 are fixed on the top of the sampling cylinder 23 and oppositely arranged, the contact plate 31 is fixed on the outer circumferential surface of the sampling column 26 and cooperates with the first limiting plate 29 and the second limiting plate 30, and the two rotating positions of the sampling column 26 are limited by the first limiting plate 29 and the second limiting plate 30.

[0050] When the sampling column 26 rotates to the sampling groove 27 and the through groove 25 are coincided, the contact plate 31 is in contact with the second limiting plate 30 at this time; when the sampling column 26 rotates to the sampling groove 27 and the through groove 25 are opposite, the contact plate 31 is in contact with the first limiting plate 29 at this time.

[0051] The utility model discloses a planet machine sampling mechanism for heat conduction silicon gel, which stirs the material in the stirring box 1 through the stirring assembly, and when sampling, the sampling cylinder 23 is driven to descend by the lifting cylinder 21 (in the descending process, to avoid that the material in the stirring box 1 penetrates into the insertion slot 24 through the through groove 25, the sampling column 26 rotates to the contact plate 31 and the first limiting plate 29 are in contact at this time, as shown in the figure). Figure 7

[0052] After descending to the specified depth, the operator rotates the sampling column 26 to the contact plate 31 and the second limiting plate 30 are in contact, as shown in the figure, at this time, the sampling groove 27 and the through groove 25 are coincided, the material in the stirring box 1 will flow into the sampling groove 27 through the through groove 25, and then the sampling column 26 is continuously rotated to the contact plate 31 and the first limiting plate 29 are in contact, to avoid that the material in the sampling groove 27 flows out in the pulling-out process. Figure 6

[0053] The lifting cylinder 21 drives the lifting plate 20 to ascend to the sampling cylinder 23 being pulled out from the stirring box 1, the silicon gel adhered to the periphery of the sampling cylinder 23 is scraped back into the stirring box 1 through the feeding port 3, and finally the operator pulls out the sampling column to detect the silicon gel in the sampling groove 27.

[0054] Further, different samples at different heights in the stirring box 1 can be taken for detection during sampling, the universality is stronger, and the detection result is more accurate.
