The bottom of the two connecting rods 242 are respectively hinged to the front and rear sides of the sliding plate 222 through the rotating shaft 243.

[0028] The self-feeding assembly 25 includes a ratchet ring 251, a locking block fixing shaft 252, a locking block 253, a compression spring 254, a feeding roller 255, a rack 256, and a fixing block 257.

The bottoms of the two fixing blocks 257 are fixedly connected to the left and right sides of the top of the base 1 respectively. A damping shaft, which is mature in the field, is installed between the outer wall of the clamping block fixed shaft 252 and the inner wall of the fixing block 257, so that the clamping block fixed shaft 252 can be freely suspended at any angle. The bottom side of the feeding roller 255 abuts against the material to be sampled. The ratchet ring 251 is located between the fixed block 257 and the end of the feeding roller 255.

[0029] In this utility model, the operator drives the right end of the pressure rod 241 downward, causing the pressure rod 241 to drive the sliding plate 222 to move downward through the connecting rod 242; the downward movement of the sliding plate 222 causes the limiting roller 232 to slide in a limited position with the limiting rod 231; at the same time, the downward movement of the sliding plate 222 causes the sliding plate 223 to move downward through the limiting rod 224; when the sliding plate 223 abuts against the pressure block 213, the sliding plate 222 continues to move downward to compress the spring 225 while sliding in a limited position with the limiting rod 224, at which time the pressure knife 221 presses down to cut the sampling material and enters the sampling chamber 211 through the pressure groove 212.

[0030] During the downward pressing of the pressure rod 241, the rack 256 moves downward, causing the ratchet ring 251 to rotate. The ratchet teeth inside the ratchet ring 251 cause it to rotate forward. At this point, the locking block 253 presses down on the compression spring 254, causing the ratchet ring 251 to rotate relative to the locking block's fixed shaft 252. Figure 5 In the middle, the ratchet ring 251 rotates counterclockwise), the locking block 253 slides against the inner wall of the ratchet ring 251, and the ratchet ring 251 cannot drive the fixed shaft 252 to rotate counterclockwise ( Figure 5(Middle view state) Rotation; After pressure cutting and sampling, the operator releases the pressure rod 241; Spring 233 pushes the limit slide roller 232 and the sliding plate 222 to move upward and reset; The upward and reset sliding plate 222 drives the pressure rod 241 to reset; At the same time, Spring 225 pushes the sliding plate 223 to move upward and reset; At this time, the rack 256 drives the ratchet ring 251 to rotate, and the ratchet teeth on the inner wall of the ratchet ring 251 drive the locking block fixing shaft 252 to rotate through the locking block 253. The rotation of the locking block fixing shaft 252 drives the feeding roller 255 to rotate. Since the bottom side of the feeding roller 255 is in contact with the material to be sampled, the rotation of the feeding roller 255 drives the material to be sampled forward ( Figure 5 Move from center to left to achieve continuous automatic feeding and sampling.

[0031] In some embodiments, the self-sampling mechanism 3 includes a sampling drive assembly 31 and a sampling assembly 32; two sets of sampling drive assemblies 31 are symmetrically distributed on the front end of the sliding plate 222, the top of the sampling drive assembly 31 is hinged to the sliding plate 222, the bottom of the sampling drive assembly 31 is hinged to the sampling assembly 32, the sampling assembly 32 is connected to the top front end of the base 1, and the sampling assembly 32 is connected to the pressure bearing assembly 21; the sampling drive assembly 31 is used to drive the sampling assembly 32; the sampling assembly 32 is used to automatically remove the sample from under the pressure bearing assembly 21.

[0032] Specifically, the sampling drive assembly 31 includes connecting blocks 311 and connecting rods 312. The rear ends of the two connecting blocks 311 are fixedly connected to the left and right sides of the front end of the sliding plate 222, respectively. The tops of the two connecting rods 312 are hinged to the front ends of the two connecting blocks 311, respectively. The bottoms of the two connecting rods 312 are hinged to the front ends of the left and right sides of the sampling assembly 32, respectively.

[0033] The sampling assembly 32 includes a sliding block 321; the front sides of the left and right ends of the sliding block 321 are respectively hinged to the bottom of two drive assemblies 31 via hinge shafts; a sampling groove 323 for placing samples is provided on the top of the sliding block 321; a limiting groove 322 for limiting the sliding of the sliding block 321 is provided on the front surface of the pressure block 213; and clearance grooves 324 are provided on the front sides of the left and right ends of the pressure block 213; the clearance grooves 324 are used to avoid the hinge shafts connecting the sliding block 321 and the drive assembly 31; wherein, the bottom of the two connecting rods 312 are respectively hinged to the front ends of the left and right sides of the sliding block 321 via hinge shafts. When the sliding block 321 is inserted into the limiting groove 322, the sampling groove 323 communicates with the sampling chamber 211.

[0034] In this invention, the operator pushes the pressure rod 241 to drive the pressure knife 221 to cut and sample the material to be sampled. During cutting, the sliding plate 222 moves down and drives the sliding block 321 to slide backward within the limiting groove 322 via the connecting rod 312. The cut sample falls from the pressure groove 212 into the sampling slot 323 inside the sampling chamber 211. After sampling is completed, the sliding plate 222 moves up and drives the sliding block 321 to slide forward within the limiting groove 322 via the connecting rod 312. The sampling slot 323 slides out from the sliding block 321, making it convenient for the operator to remove the cut sample from inside the sampling slot 323.
