[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] See also Figure 1-4 , the utility model provides a technical solution: a sampler for automatic sampling of inoculant, comprising: a sampling discharge pipe 4 and a rotating shaft 6 arranged at the lower side of the side of the inoculant high-level silo 1;

[0028] The upper end of the sampling discharge pipe 4 extends to the interior of the inoculant high-level silo 1, and the upper side of one end of the sampling discharge pipe 4 located inside the inoculant high-level silo 1 is closed. A feed port 5 is provided on the side wall of the sampling discharge pipe 4 located at one end inside the inoculant high-level silo 1, and the rotating shaft 6 is rotatably connected to the upper end of the sampling discharge pipe 4, and the lower end of the rotating shaft 6 extends to the interior of the sampling discharge pipe 4. A valve plate 7 is provided inside the sampling discharge pipe 4, and the valve plate 7 is set in a semi-cylindrical shape. The position of the valve plate 7 corresponds to the position of the feed port 5, and the inoculant high-level silo 1 is provided with a driving mechanism for driving the rotating shaft 6 to rotate.

[0029] Analysis of the above content: When in use, the inoculant is added to the inoculant high-level silo 1 in advance, and the sampling method is set according to the capacity of the inoculant high-level silo 1. For example, if the capacity of the inoculant high-level silo 1 is 1 ton, three samples are taken before the inoculant in the inoculant high-level silo 1 is packed; if the capacity of the inoculant high-level silo 1 is 2 tons, six samples are taken before the inoculant in the inoculant high-level silo 1 is packed, and so on. The following is a description of the case where the capacity of the inoculant high-level silo 1 is 1 ton:

[0030] Under the action of gravity, the inoculant enters the inoculant high-level silo 1 from the material inlet 2 of the inoculant high-level silo 1 and is output from the material outlet 3 of the inoculant high-level silo 1. During this process, sampling is performed three times within the range of 1 / 3 of the total amount of the output inoculant, within the range of 2 / 3 of the total amount of the output inoculant, and within the remaining inoculant. When sampling, the rotating shaft 6 is driven to rotate by the driving mechanism, and the rotating shaft 6 drives the valve plate 7 to rotate, such as Figure 4 As shown, the valve plate 7 is semi-cylindrical. When the arc surface of the valve plate 7 corresponds to the feed port 5, the feed port 5 can be closed, so that the inoculant cannot enter the sampling discharge pipe 4 through the feed port 5; when the flat surface of the valve plate 7 corresponds to the feed port 5, the feed port 5 is not blocked, and the inoculant can enter the sampling discharge pipe 4 through the feed port 5 for sampling (this sampling method is also applicable to other similar sampling operations).

[0031] Embodiment 2:

[0032] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: the upper end of the rotating shaft 6 extends to the upper surface of the inoculant high-level silo 1, and the driving mechanism includes a swing arm 13 connected to the upper end of the rotating shaft 6, and one side of the outer wall of the swing arm 13 is fixedly connected to the upper end of the rotating shaft 6 by screws. The driving mechanism also includes a driving motor 9 arranged on the upper side of the side wall of the inoculant high-level silo 1, and a rotating disk 11 is connected to the upper side of the driving motor 9, and one side of the rotating disk 11 is rotatably connected to a connecting rod 12 through a pin shaft, and the other end of the connecting rod 12 is rotatably connected to the other side of the outer wall of the swing arm 13.

[0033] Analysis of the above content: the output shaft of the driving motor 9 can drive the turntable 11 to rotate, and the edge of the turntable 11 drives the connecting rod 12 to swing. The swing of the connecting rod 12 can drive the swing arm 13 to rotate, and the swing arm 13 drives the rotating shaft 6 to rotate.

[0034] Embodiment three:

[0035] See also Figure 1-4 The utility model provides a technical solution based on the second embodiment: the upper surface of the inoculant high-level silo 1 is provided with a bearing seat 14, a bearing is installed in the bearing seat 14, and the upper end of the rotating shaft 6 is inserted into the inner ring of the bearing.

[0036] Analysis of the above content: Through the arrangement of the bearing seat 14 and the bearing, the shaft 6 has less resistance when rotating and runs smoothly.

[0037] Embodiment 4:

[0038] See also Figure 1-4The utility model provides a technical solution based on the second embodiment: the driving mechanism also includes a reducer 10, the input end of the reducer 10 is connected to the output shaft of the driving motor 9, and the upper side of the output end of the reducer 10 is connected to the turntable 11.

[0039] Analysis of the above content: Through the setting of the reducer 10, the rotation speed of the output terminal turntable 11 is slowed down, which plays a role of reducing speed and increasing torque, making it convenient to control the rotation angle.

[0040] Embodiment five:

[0041] See also Figure 1-4 The utility model provides a technical solution based on the second embodiment: two proximity switches 16 are arranged on the upper surface of the inoculant high-level silo 1, and a sensing plate 15 is arranged at one end of the swing arm 13 away from the connecting rod 12, and the sensing plate 15 corresponds to the position of the two proximity switches 16.

[0042] Analysis of the above content: the proximity switch 16 adopts the existing technology, and the sensor plate 15 is a conventional shielding plate. When the sensor plate 15 moves to one of the proximity switches 16 with the rotation of the swing arm 13, the proximity switch 16 detects the movement of the sensor plate 15, and the proximity switch 16 outputs a signal (output to an external PLC, based on the PLC to control the drive motor 9), which is used to control the start and stop of the drive motor 9. In this way, the sensor plate 15 is limited to rotate within the range between the two proximity switches 16, which limits the rotation angle of the rotating shaft 6.

[0043] Embodiment six:

[0044] See also Figure 1-4 The utility model provides a technical solution based on the fifth embodiment: a protective cover 8 is provided on the upper side of the inoculant high-level silo 1, and the bearing seat 14, the turntable 11, the connecting rod 12, the swing arm 13, the induction plate 15, and the proximity switch 16 are all located in the protective cover 8.

[0045] Analysis of the above content: The protective cover 8 protects the bearing seat 14, the turntable 11, the connecting rod 12, the swing arm 13, the sensor plate 15, the proximity switch 16 and other structures, and plays a role in dustproof, waterproof and collision-proof.
