[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0020] Embodiments of the present invention: Figure 1-Figure 4 As shown, a tobacco sampling device includes a placement platform 1, the bottom of the placement platform 1 is provided with supporting legs, the top of the placement platform 1 is provided with four lifting cylinders 2, the telescopic rods of the lifting cylinders 2 are vertically arranged upward, the mounting frame 3 is fixedly installed on the telescopic rods of the four lifting cylinders 2, the mounting frame 3 is provided with a stirring sampling mechanism, the top of the mounting frame 3 is provided with a driving assembly 4, and the driving assembly 4 is connected to the stirring sampling mechanism.

[0021] Two lifting cylinders 2 are respectively arranged at both ends of the placement platform 1, and the four lifting cylinders 2 are arranged in a rectangular shape. The lifting cylinders 2 are used to adjust the height of the mounting frame 3. When placing the tobacco box on the placement platform 1, the mounting frame 3 needs to be lifted up first, so that the stirring sampling mechanism in the mounting frame 3 will not interfere. After placing the tobacco box, the mounting frame 3 is lowered by the lifting cylinders 2, so that the stirring sampling mechanism enters the tobacco box. Driven by the driving component 4, the stirring sampling mechanism stirs and mixes the tobacco.

[0022] In a specific embodiment, the driving assembly 4 includes an output motor 401 and a connecting frame 402. The output motor 401 is fixed to the top of the mounting frame 3 through a motor mounting bracket 410. The output shaft of the output motor 401 is arranged vertically downward and passes through the top plate of the mounting frame 3. The connecting frame 402 is fixedly mounted on the output shaft of the output motor 401.

[0023] The stirring sampling mechanism includes a driven gear 403, an inner gear ring 404, a protective shell 405, an output cylinder 406, a transmission gear 408, a transmission plate 409, a sampling disc 4010 and a gear plate 4011. The connecting frame 402 is provided with two vertical rods and a horizontal rod. The two vertical rods are fixed at both ends of the horizontal rod. A driven gear 403 is rotatably installed at the lower ends of the two vertical rods. The inner gear ring 404 is fixedly connected to the inner wall of the mounting frame 3 through a connecting rod, and the two driven gears 403 are meshed with the inner gear ring 404.

[0024] The output shaft of the output motor 401 is fixedly connected to the middle position of the horizontal rod of the connecting frame 402, the driven gear 403 is coaxial with the vertical rod, the inner gear ring 404 is arranged horizontally, and the inner gear ring 404 is coaxial with the output shaft of the output motor 401, thereby ensuring that when the output motor 401 is working, the two driven gears 403 on the connecting frame 402 are always engaged with the inner gear ring 404.

[0025] A protective shell 405 is fixedly provided on the bottom surface of each of the two driven gears 403 . An output cylinder 406 is fixedly provided in the protective shell 405 . The telescopic rod of the output cylinder 406 is arranged vertically downward. A tooth plate 4011 is fixedly provided on the telescopic rod of the output cylinder 406 .

[0026] In this embodiment, the protective shell 405 is a cylindrical shell, so that the outer wall of the protective shell 405 is a smooth outer wall, which will not cause damage to the tobacco when the protective shell 405 rotates, thereby preventing the tobacco from generating a large amount of fragments.

[0027] A limit frame 407 is fixedly provided at the lower end of the two protective shells 405, and the lower end of the tooth plate 4011 passes through the bottom plate of the protective shell 405 and the limit frame 407. Two transmission gears 408 are rotatably installed in the two limit frames 407, and the transmission gears 408 are meshed with the tooth plate 4011. Two transmission plates 409 are installed on the two limit frames 407, one end of the transmission plate 409 is fixedly connected to the transmission gear 408, and the other end of the transmission plate 409 is fixedly provided with a sampling tray 4010.

[0028] The two transmission gears 408 in the same limit frame 407 are installed on both sides of the tooth plate 4011. Teeth are formed on both side surfaces of the tooth plate 4011. When the tooth plate 4011 moves, the two transmission gears 408 are driven to rotate at the same time, thereby changing the angle of the transmission plate 409. The transmission plate 409 is a bent plate. The sampling disk 4010 at the lower end of the transmission plate 409 is a circular disk, and the opposite surfaces of the two sampling disks 4010 are formed with recessed portions.

[0029] Furthermore, a fixing assembly 5 is provided on the placement platform 1, and the fixing assembly 5 includes a transmission motor 501, a bidirectional lead screw 502, an internal threaded barrel 503 and a fixing plate 504. A slideway is provided on the placement platform 1, and the transmission motor 501 is fixedly installed on one side of the placement platform 1. One end of the bidirectional lead screw 502 is fixedly installed on the output shaft of the transmission motor 501, and the other end of the bidirectional lead screw 502 is rotatably installed at the bottom of the placement platform 1. There are two internal threaded barrels 503, which are respectively threadedly connected to the two ends of the bidirectional lead screw 502, and one end of the fixing plate 504 passes through the slideway and is fixedly installed on the top of the internal threaded barrel 503.

[0030] The working principle of the present invention is as follows: when working, the four lifting cylinders 2 are controlled to extend to make the mounting frame 3 rise, and then the tobacco box is placed on the placing platform 1, and the transmission motor 501 is energized to make it work. After the transmission motor 501 is energized, it can drive the bidirectional screw 502 to rotate. The rotating bidirectional screw 502 can transmit the fixed plate 504 through the mutual cooperation with the internal threaded tube 503, and then the two fixed plates 504 can be clamped on both sides of the tobacco box, so that the tobacco box can be fixed to prevent the tobacco box from shifting during stirring. After the tobacco box is fixed, the transmission motor 501 stops working.

[0031] Then the four lifting cylinders 2 are controlled to retract, so that the mounting frame 3 descends, and the two stirring sampling mechanisms are inserted into the tobacco.

[0032] When the output motor 401 is powered on, the output motor 401 can drive the protective shell 405 to move around the inner gear ring 404 through the connecting frame 402. At the same time, under the meshing action of the driven gear 403 and the inner gear ring 404, the protective shell 405 rotates, and the tobacco is fully stirred and mixed through the transmission plate 409 and the sampling disk 4010, which can avoid the problem of deviation in the sampling results.

[0033] After stirring and mixing, the output motor 401 stops working. When the tobacco needs to be sampled, the output cylinder 406 drives the tooth plate 4011 to move, and then the tooth plate 4011 and the transmission gear 408 are engaged with each other to drive the transmission plate 409 to rotate, and then the transmission plate 409 drives the sampling disk 4010 to close. When the sampling disk 4010 is closed, the tobacco can be clamped, thereby achieving the purpose of sampling the tobacco.

[0034] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
