[0065] By adopting the above technical scheme, when it is necessary to crush and sample fruits and vegetables, first open the sealing device, then put the fruit and vegetable samples to be crushed into the crushing device, then close the sealing device, and control the crushing device to start working through the operating device on the top of the chassis 1, and then crush the fruit and vegetable samples through the crushing device. After the fruit and vegetable samples are crushed, pour out the crushed fruit and vegetable samples through the pouring device. The user can drive the power supply device and the chassis 1 to a suitable position through the moving device, which is convenient for operation. It is also convenient to take the device outdoors for use, and the movement is more convenient. By setting a separate movable power supply device, the power supply device can power the chassis 1 after storing electricity, which can ensure that the chassis 1 can work for a long time, and the chassis 1 can be free from the restrictions of the site power supply factors when working, so as to realize flexible sampling anytime and anywhere.

[0066] In some embodiments, the unloading device includes: a support seat 21, which is arranged on one side of the chassis 1; a rotating rod 22, which is rotatably arranged on both sides of the upper side of the support seat 21, and there are two rotating rods 22, and a threaded circular hole is penetrated on the rotating rod 22 on the side away from the operating device; a support frame 23, which is arranged between the rotating rods 22 on both sides, and the crushing device is arranged on the support frame 23; a chuck 24, which is arranged on the side of the chassis 1 away from the charging port, and the adjacent rotating rods 22 pass through the center position of the chuck 24; an operating rod 25, which is arranged in the threaded circular hole on the rotating rod 22, and the operating rod 25 is clamped with the chuck 24; a locking rod 26, which is slidably arranged on one side of the chuck 24, and the locking rod 26 penetrates into the rotating rod 22.
