The second motor is started, and the output shaft of the second motor drives the auger to rotate, transfer it to the discharge plate and re-enter the preparation box for further crushing, thereby avoiding the situation where some incompletely crushed particles are mixed in the crushed powder, which may reduce the processing effect if they are not picked out.
[0007] Preferably, two slide grooves are provided on the preparation box, and a mounting bracket is provided on the sieve plate, and the mounting bracket is slidably connected to the slide grooves.
[0008] The effect achieved by the above components is that the up and down sliding mounting frame drives the screen plate to oscillate up and down, thereby improving the screening efficiency.
[0009] Preferably, two racks are fixedly connected to the mounting frame, and half gears are meshedly connected to the racks.
[0010] The effect achieved by the above components is: when the half gear rotates and the half gear and the rack engage with each other, it will drive the rack to slide upward.

[0014] The effect achieved by the above components is: opening the door panel makes it easy to replace the sieve plate to adapt to different preparation size requirements. After the sieve plate is installed in the mounting frame, sliding the card block into the corresponding card slot can limit the sieve plate.
[0015] Preferably, a sliding plate is slidably connected in the sliding groove, the sliding plate is fixedly connected to the clamping block, and a connecting rod is fixedly connected to both sliding plates.
[0016] The effect achieved by the above components is that the two sliding plates can be driven to slide synchronously through the sliding connecting rod, thereby driving the clamping block to slide.
[0017] Preferably, a spring is fixedly connected to the sliding plate, and one end of the spring is fixedly connected to the inner wall of the sliding groove.
[0018] The effect achieved by the above components is that when the card block is inserted into the card slot, the spring is in a contracted state, so the rebound force of the spring acts on the sliding plate, making the limit more stable.
[0019] Preferably, a knob is rotatably connected to the screen plate, two pull ropes are fixedly connected to the knob, and the pull ropes are fixedly connected to the connecting rod.
[0020] The effect achieved by the above components is that turning the knob can drive the two pull ropes to wind, and then drive the two connecting rods to slide closer synchronously, making the disassembly operation more convenient.
