[0026] Embodiment 3

[0027] Please refer to Figures 1-4 As shown, based on the first and second embodiments, a limiting component 6 is provided on the moving rod 2. The limiting component 6 includes a chute 61 opened on one of the moving rods 2. A slider 62 is slidably installed in the chute 61. A limiting plate 63 is fixedly installed on the side of the slider 62 close to the rotating rod 41. The limiting plate 63 functions to limit and stabilize the rotating rod 41. A special-shaped elastic piece 64 with a round hole is fixedly installed on the side of the slider 62 close to the rotating rod 41. The special-shaped elastic piece 64 functions to drive the elastic reset of the slider 62. When the moving rod 2 slides in the reciprocating block 53, the reciprocating block 53 drives the slider 62 to slide on the guide rod 65 and squeeze the special-shaped elastic piece 64 through the limiting plate 63, so that the special-shaped elastic piece 64 is in a compressed state. The end of the special-shaped elastic piece 64 away from the slider 62 is fixedly installed on the inner wall of the chute 61. A guide rod 65 is slidably penetrated through the slider 62. The guide rod 65 functions to guide and limit the slider 62. Both ends of the guide rod 65 are fixedly installed at both ends of the chute 61. The guide rod 65 is slidably penetrated through the round hole of the special-shaped elastic piece 64, which functions to stabilize the special-shaped elastic piece 64.

[0028] A receiving groove 66 is opened at one end of the other moving rod 2 close to the rotating rod 41. A triangular block 69 is slidably installed in the receiving groove 66. An inclined surface is opened at one end of the triangular block 69 away from the baffle 413. The triangular block 69 functions to limit and stabilize the rotating rod 41. A spring 68 and a pull rod 67 are fixedly installed on the side of the triangular block 69 away from the rotating rod 41. The other end of the pull rod 67 slidably penetrates through the moving rod 2. The pull rod 67 drives the triangular block 69 to retract into the receiving groove 66 and squeeze the spring 68, so that the spring 68 is in a compressed state. The other end of the spring 68 is fixedly installed on the inner wall of the receiving groove 66. The spring 68 is nested on the outer surface of the pull rod 67. The spring 68 functions to drive the elastic reset of the triangular block 69, so that the triangular block 69 cooperates with the baffle 413 to limit and fix the rotating rod 41, which is convenient for limiting the rotating rod 41 in the vertical direction and the horizontal direction, convenient for limiting and stabilizing the rotating rod 41, beneficial to improving the limiting stability of the device, and beneficial to improving the flexible stability of the device.

[0029] Working principle of the present invention: When using the device, when sampling in different horizontal regions, first, the sampling bottle is placed on the placement plate 49 by squeezing the clamping elastic piece 48, then the rotating cover 410 is started to move downward to seal the sampling bottle, and then when the first motor 414 is started, the output end of the first motor 414 drives the winding roller 415 to rotate and wind the winding rope 417 on the support plate 416. At the same time, the winding rope 417 drives the rotating rod 41 to rotate onto the baffle 413. At the same time, the rotating rod 41 slides on the inclined surface of the triangular block 69 to squeeze the triangular block 69. At the same time, the triangular block 69 contracts into the receiving groove 66 to squeeze the spring 68 and the pull rod 67. At the same time, the pull rod 67 slides on the moving rod 2. At the same time, the spring 68 is in a compressed state. When the rotating rod 41 moves onto the baffle 413, the elastic restoring force of the spring 68 drives the triangular block 69 to elastically reset and limit the rotating rod 41. Then, the moving frame 1 is pushed to the raw material barrel to be detected. Then, the second motor 57 and the third motor 58 are started. The output end of the second motor 57 drives the reciprocating screw rod 52 to rotate. At the same time, the reciprocating screw rod 52 drives the reciprocating block 53 to slide in the rectangular through hole 51. At the same time, the output end of the third motor 58 drives the reciprocating screw rod 56 to rotate on the reciprocating block 53. At the same time, the reciprocating screw rod 56 drives the connecting plate 3 to move downward in the mounting frame 55. At the same time, the connecting plate 3 drives the moving rod 2 to slide downward on the reciprocating block 53. At the same time, the elastic restoring force of the special-shaped elastic piece 64 drives the slider 62 to slide in the chute 61. At the same time, the slider 62 drives the limiting plate 63 to elastically reset on the guide rod 65. At the same time, the first electric telescopic rod 42 is started. The first electric telescopic rod 42 drives the pushing frame 43 to push the diamond-shaped extension frame 45, so that the diamond-shaped extension frame 45 extends to adjust the distance between the two sampling bottles. At the same time, the moving rod 2 continues to descend. Then, the rotating cover 410 is rotated to open the sampling bottle, so that the sampling bottle on the diamond-shaped extension frame 45 is filled with the milk powder whey to be detected. Then, the rotating cover 410 is rotated to seal the sampling bottle filled with milk powder whey. Then, the third motor 58 is started in the reverse direction. The third motor 58 drives the reciprocating screw rod 56 to rotate. At the same time, the reciprocating screw rod 56 drives the connecting plate 3 to move upward, so that the connecting plate 3 drives the rotating rod 41 on the moving rod 2 to move upward. At the same time, the rotating rod 41 drives the sampling bottle to leave the raw material liquid through the diamond-shaped extension frame 45. Then, the second electric telescopic rod 412 is started. The second electric telescopic rod 412 moves in the waist-shaped through hole 411 to push out the sampling bottle clamped by the clamping elastic piece 48 from the placement plate 49 for convenient blanking operation; When sampling at different depths in the vertical direction of the raw materials, after the sampling is installed, then reverse-start the first motor 414 to loosen the winding rope 417 on the winding roller 415, and then pull the pull rod 67 to drive the triangular block 69 to squeeze the spring 68 by the pull rod 67. The spring 68 is in a compressed state. At the same time, make the rotating rod 41 rotate to the limiting plate 63 under the action of the gravity of the diamond-shaped extension frame 45, and then repeat the extension operation of the diamond-shaped extension frame 45 above. Then start the third motor 58 to drive the moving rod 2 to move downward through the reciprocating lead screw 56 and the connecting plate 3, and at the same time drive the sampling bottle to move to the required position. Then start the rotary capping 410 to fill the sampling bottle. After the filling is completed, start the rotary capping 410 again to block the sampling bottle. Then contract the rotating rod 41 and reverse-start the third motor 58 to make the sampling bottle move upward. Then start the second electric telescopic rod 412 to perform the operation of pushing and discharging the sampling bottle on the placement plate 49.

[0030] The above has described an embodiment of the present invention in detail, but the content described is only a preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
