[0021] like Figure 1-4 A sample recovery and processing device for detection shown in the figure includes a recovery barrel 1 and a crushing assembly 2 arranged inside the recovery barrel 1; the crushing assembly 2 includes two groups of crushing rollers 21 arranged inside the recovery barrel 1, an adjusting screw bearing seat 22 fixed to the outside of the recovery barrel 1, and a pressure roller 23 arranged outside the recovery barrel 1, and the two groups of crushing rollers are respectively fixed on the outer surfaces of the first shaft 24 and the second shaft 26.

[0022] In this embodiment: when it is necessary to adjust the distance between the two sets of crushing rollers 21, by rotating the first rotating screw 27, the adjusting threaded block 28 drives the second bearing seat to slide inside the slide groove of the recycling barrel 1, so that the distance between the second shaft rod 26 is adjusted to be farther or closer, thereby adapting to the size of the food to be crushed and achieving rapid crushing.

[0023] The first shaft 24 is rotatably connected to the inside of the recycling bin 1 through the first bearing seat group. Two sets of slide grooves are provided inside the recycling bin 1. The second bearing seat group 25 is slidably connected to the inside of the slide groove. The central axis of the second bearing seat group 25 is slidably connected to the second shaft 26. The two sets of crushing rollers 21 rotate in opposite directions. When food enters, the food is crushed.

[0024] The central axis of the adjusting screw bearing seat 22 is rotatably connected to the first rotating screw 27, and the outer surface of the first rotating screw 27 is threadedly connected to the adjusting thread block 28, and one side of the adjusting thread block 28 is fixed to the outer axis of the second bearing seat assembly 25. By rotating the first rotating screw 27, the adjusting thread block 28 drives the second bearing seat to slide inside the slide groove of the recycling bin 1, so that the spacing of the second shaft 26 is adjusted to be farther or closer, so as to adapt to the size of the food to be crushed and achieve rapid crushing.

[0025] A first gear 29 is fixed to the outer surface of one end of the first shaft 24, and a second gear 201 is rotatably connected to the outer surface of the recycling bin 1.

[0028] The pressure roller 23 is rotatably connected to the outer side of the adjusting slider 208, and the pressure roller 23 contacts the transmission belt 204. The pressure roller 23 descends, so that the transmission belt 204 wraps the first transmission wheel 202 and the second transmission wheel 203.

[0029] During operation, when it is necessary to adjust the distance between the two groups of crushing rollers 21, by rotating the first rotating screw 27, the adjusting threaded block 28 drives the second bearing seat to slide inside the slide groove of the recycling bin 1, so that the distance between the second shaft rod 26 is adjusted to be farther or closer, so as to adapt to the size of the food to be crushed and achieve rapid crushing. Before crushing is required, the second rotating screw 207 is rotated, and the second rotating screw 207 drives the adjusting slider 208 to slide on the track of the roller screw bearing seat 206, so that the pressure roller 23 is lowered, and the transmission belt 204 wraps the first transmission wheel 202 and the second transmission wheel 203. During crushing, by driving the crushing motor 205, the crushing motor 205 drives the first gear 29 to rotate, and the first gear 29 drives the first shaft rod 24 to rotate, and the second gear 201 meshing with the first gear 29 drives the second shaft rod 26 to rotate through the first transmission wheel 202 and the second transmission wheel 203, so that the two groups of crushing rollers 21 rotate in opposite directions, and when food enters, the food is crushed.

[0030] In summary, when the device needs to adjust the distance between the two sets of crushing rollers 21, the first rotating screw 27 is rotated to adjust the threaded block 28 to drive the second bearing seat to slide inside the slide groove of the recycling barrel 1, so that the distance between the second shaft rod 26 is adjusted to be farther or closer, thereby adapting to the size of the food to be crushed and achieving rapid crushing.
