[0030] Please refer to Figures 1 - 6 , the present utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problems that in the use of a bulk grain sampling sample mixing and intelligent sample splitting device on the market, currently in the use of the mixing and sample splitting device on the market, it is not easy to add and fully mix the mixed samples according to the use requirements, realize intelligent sample splitting after mixing, and it is impossible to perform quantitative sample splitting and discharging control on bulk grain, and it is not convenient for multiple discharging operations during discharging;

[0032] Reference can be made to Figure 1 - Figure 6 , including a support frame 2 and a sample mixing tank 13. A weighing sensor 1 is fixedly installed at the bottom on the left side of the support frame 2. A motor body 3 is arranged on the left side of the support frame 2. The output shaft of the motor body 3 is fixedly connected to a rotating shaft 4 through a coupling and penetrates through the support frame 2 at one end; a turntable 5 is fixedly installed on the right side of the rotating shaft 4, and the turntable 5 is fixedly connected to a mounting seat 6 on the right side; the rotating shaft 4 and the turntable 5 are fixedly connected, and a torsion detection device is sleeved on the outer wall on the right side of the rotating shaft 4. After an appropriate amount of bulk grain enters the sample mixing tank 13, the external control board is used to start the motor body 3. The motor body 3 uses a stepping motor or a servo motor, and its rotation speed and frequency can be adjusted. The output shaft of the motor body 3 drives the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the mounting seat 6 and the sample mixing tank 13 connected to the fixing plate 12 through the turntable 5 to rotate, and the sample mixing tank 13 drives the sampled bulk grain to be mixed, realizing the mixing of the sampled bulk grain and facilitating subsequent intelligent sample splitting.

The inlet - outlet pipe 15 and the valve body 16 are connected and communicated through a flange connection, and the valve body 16 is used to control the grain flow; the staff connects the inlet - outlet pipe 15 with the external bulk grain conveying pipeline through the valve body 16, and after the bulk grain is sampled and mixed, the valve body 16 is controlled to start working through an external computer program according to the customer's usage requirements. A motor is arranged on the valve body 16, and the internal valve is driven by the motor to move back and forth for discharging or feeding; under the action of the valve body 16, the sample processed by mixing in the mixing tank 13 is discharged through the inlet - outlet pipe 15 and the valve body 16, so as to perform sub - sampling on the mixed bulk grain; among them, the inlet - outlet pipe 15 and the valve body 16 act synchronously, and the mixing tank 13 can also be fed during use; the cleaning material pipe 14 is in a closed state under normal conditions and is opened when the inside of the mixing tank 13 needs to be cleaned.
