[0040] Example 3

[0041] See also Figures 1-4 As shown, on the basis of the first and second embodiments, a limit assembly 6 is provided on the mobile rod 2, and the limit assembly 6 includes a slide groove 61 provided on one of the mobile rods 2, a slider 62 is slidably installed in the slide groove 61, and a limit plate 63 is fixedly installed on the side of the slider 62 close to the rotating rod 41. The limit plate 63 plays the role of limiting and stabilizing the rotating rod 41, and a special-shaped spring piece 64 with a circular hole is fixedly installed on the side of the slider 62 close to the rotating rod 41. The special-shaped spring piece 64 plays the role of driving the slider 62 to elastically reset. The mobile rod 2 is in the reciprocating block 53 When sliding inward, the reciprocating block 53 drives the slider 62 through the limit plate 63 to slide on the guide rod 65 to squeeze the special-shaped spring piece 64, so that the special-shaped spring piece 64 is in a compressed state. The end of the special-shaped spring piece 64 away from the slider 62 is fixedly installed on the inner wall of the slide groove 61. The guide rod 65 is installed on the slider 62 for sliding through. The guide rod 65 plays the role of guiding the limit slider 62. The two ends of the guide rod 65 are fixedly installed on the two ends of the slide groove 61. The guide rod 65 slides through the circular hole of the special-shaped spring piece 64, which plays the role of stabilizing the special-shaped spring piece 64.

[0042] The other end of the pull rod 67 slides through the moving rod 2, and the pull rod 67 drives the triangular block 69 to retract into the receiving groove 66 to squeeze the spring 68, so that the spring 68 is in a compressed state. The other end of the spring 68 is fixedly mounted on the inner wall of the receiving groove 66, and the spring 68 is nested on the outer surface of the pull rod 67. The spring 68 plays the role of driving the triangular block 69 to elastically reset, 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 rotating rod 41 in the horizontal direction, and conveniently limiting and stabilizing the rotating rod 41, which is beneficial to improving the limiting stability of the device and the flexible stability of the device.

[0043] The working principle of the present invention is as follows: when using the device, when sampling in different areas in the horizontal direction, first squeeze the sampling bottle and clamp the spring piece 48 to place it on the placement plate 49, then start the rotary cover 410 to move downward to seal the sampling bottle, and then start the first motor 414, so that the output end of the first motor 414 drives the winding roller 415 to rotate on the support plate 416 to wind the winding rope 417, and at the same time, the winding rope 417 drives the rotating rod 41 to rotate to the baffle 413, and at the same time, the rotating rod 41 slides on the inclined surface of the triangular block 69 to squeeze the triangular block 69, and at the same time, the triangular block 69 retracts into the storage groove 66 to squeeze the spring 68 and the pull rod 67, and at the same time make the pull rod 67 slide on the moving rod 2, and at the same time make the spring 68 in a compressed state. When the rotating rod 41 moves to the baffle 413, the elastic reset force of the spring 68 drives the triangular block 69 to elastically reset the limit rotating rod 41, and then pushes the mobile rack 1 to move to the raw material barrel that needs to be detected, and then starts the second motor 57 and the third motor 58, so that the output end of the second motor 57 drives the reciprocating screw 52 to rotate, and at the same time makes the reciprocating screw 52 drive the reciprocating block 53 to slide in the rectangular through hole 51, and at the same time makes the output end of the third motor 58 drive the reciprocating screw 56 to rotate on the reciprocating block 53, and at the same time makes the reciprocating screw 56 The screw rod 56 drives the connecting plate 3 to move downward on the mounting frame 55, and at the same time, the connecting plate 3 drives the moving rod 2 to slide downward on the reciprocating block 53, and at the same time, the elastic restoring force of the special-shaped spring piece 64 drives the slider 62 to slide in the slide groove 61, and at the same time, the slider 62 drives the limit plate 63 to elastically reset on the guide rod 65, and at the same time, the first electric telescopic rod 42 is started, so that the first electric telescopic rod 42 drives the pushing frame 43 to push the diamond extension frame 45, so that the diamond extension frame 45 extends to adjust the distance between the two sampling bottles, and at the same time, the moving rod 2 continues to descend, and then the rotary cover 410 is rotated to open the sampling bottle, so that the sampling bottle on the diamond extension frame 45 is opened. The sample bottle is filled with milk powder and whey to be tested, and then the rotary cover 410 is rotated to seal the sample bottle filled with milk powder and whey. The third motor 58 is then started in reverse, so that the third motor 58 drives the reciprocating screw 56 to rotate, and at the same time, the reciprocating screw 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, and at the same time, the rotating rod 41 drives the sample bottle to leave the raw material liquid through the diamond-shaped extension frame 45. Then, the second electric telescopic rod 412 is started, so that the second electric telescopic rod 412 moves in the waist-shaped through hole 411 to push the sample bottle clamped by the clamping spring 48 out of the placement plate 49 to facilitate the unloading operation;

[0044] When sampling different depths of the raw material in the vertical direction, after the sampling is installed, the first motor 414 is started in reverse to make the winding roller 415 loosen the winding rope 417, and then the pull rod 67 is pulled to drive the pull rod 67 to drive the triangular block 69 to squeeze the spring 68, and the spring 68 is in a compressed state. At the same time, the rotating rod 41 is rotated to the limit plate 63 under the action of the gravity of the diamond extension frame 45, and then the extension operation of the diamond extension frame 45 is repeated. Then the third motor 58 is started again, so that the third motor 58 drives the moving rod 2 downward through the reciprocating screw rod 56 and the connecting plate 3, and at the same time drives the sampling bottle to the required position, and then the rotary cover 410 is started to fill the sampling bottle. After the filling is completed, the rotary cover 410 is started again to seal the sampling bottle, and then the rotating rod 41 is retracted and the third motor 58 is started in reverse to make the sampling bottle move upward, and then the second electric telescopic rod 412 is started to push the sampling bottle on the placement plate 49 to perform the material removal operation.
