[0018] The present invention will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, it includes: a base 1, a bracket 2 is integrally connected to the upper end of the base 1, a sampling component 4 is also integrally connected to the upper end of the base 1, a conveying and distributing component 3 is bolted to the upper end of the bracket 2, and a driving mechanism 5 is movably connected to one side of the bracket 2;

[0021] It should be noted that after installation, the conveyor belt 310, the driving roller 308, the multiple rollers 307 and the driven roller 309 can be regarded as a belt conveyor belt 310. The rotation speed of the spiral blade 304 can be controlled by adjusting the rotation speed of the first motor 305, thereby adjusting the travel speed of the waste to prevent the waste from accumulating due to too slow speed or insufficient material distribution due to too fast speed.

[0022] like Figure 3As shown, the sampling assembly 4 includes a first sampling box 401 and a second sampling box 402. The top of the first sampling box 401 is bolted to a first connecting pipe 403, and the top of the first connecting pipe 403 is inserted into the bottom wall of the inner cavity of the feeding frame 306. The second sampling box 402 is integrally connected to the outer wall of the first sampling box 401. The top of the second sampling box 402 is bolted to a second connecting pipe 404, and the second connecting pipe 404 is inserted into the feeding pipe 301.

[0023] It should be noted that the first sampling box 401 and the second sampling box 402 can be set to a push-pull type to facilitate the selection of samples.

[0024] like Figure 1 As shown, the driving mechanism 5 includes a second motor 501, which drives the driving wheel 502 to rotate. A driven wheel 503 is welded to one end of the driving roller 308. A chain 504 is nested outside the driving wheel 502 and the driven wheel 503 for use with them. The driving wheel 502 and the driven wheel 503 are both sprockets. The driven wheel 503 is fixedly connected to the driving roller 308. Driven by the driving wheel 502, the driven wheel 503 drives the driving roller 308 to rotate.

[0025] like Figure 1 As shown, one end of the delivery pipe 301 is fixedly connected to the feeding funnel 7 , and the feeding funnel 7 is welded to the delivery pipe 301 .

[0026] like Figure 3 As shown, a dust removal mechanism 6 is fixedly connected to the top of the conveying rack 306, and the dust removal mechanism 6 includes a dust suction pipe 601. One end of the dust suction pipe 601 is inserted into the top wall of the inner cavity of the conveying rack 306, and the other end of the dust suction pipe 601 is fixedly connected to a dust collector 602, so as to prevent dust from polluting the air. A through groove is provided at the top of the conveying rack 306 for the dust suction pipe 601 to absorb dust.

[0027] like Figure 1 As shown, a plurality of universal wheels 8 are fixedly connected to the bottom end of the base 1 to facilitate the movement of the device.

[0028] It should be noted that the waste enters the device from the feed hopper 7, and then the first motor 305 and the second motor 501 are started. The first motor 305 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the spiral blade 304 to rotate. Since the feeding pipe 301 has a certain inclination angle with the horizontal plane, the waste moves toward the sampling component 4 under the drive of gravity and the spiral blade 304. At the same time, the waste residue with smaller particles leaks from the through hole 303 on the side wall of the feeding pipe 301 to the conveyor belt 310. The second motor 501 drives the driving wheel 502 to rotate, and the driving wheel 502 drives the driven wheel 503 to rotate through the chain 504. The driven wheel 503 is fixedly connected to the driving roller 308, so the driving roller 308 The driven wheel 503 rotates to drive the conveyor belt 310. Multiple rollers 307 and driven rollers 309 assist the conveyor belt 310 in driving. Under the transportation of the conveyor belt 310, waste residue with smaller particles is transported to the first sampling box 401 through the first connecting pipe 403 at the tail end of the conveyor belt 310. Waste residue with larger particles cannot pass through the through hole 303, so that the waste residue with larger particles is driven by the spiral blade 304 and transported from the conveying pipe to the second connecting pipe 404 to the second sampling box 402. At the same time, more dust will be generated during the transportation process. The dust in the conveying pipe 301 and the conveying rack 306 is sucked into the vacuum cleaner 602 through the dust suction pipe 601 to prevent air pollution.

[0029] The working principle of the present invention is as follows: waste is injected into the feed funnel 7, the first motor 305 and the second motor 501 are started, the first motor 305 drives the rotating shaft 302 to drive the spiral blade 304 to rotate around the rotating shaft 302, the waste slides toward the sampling component 4 under the action of gravity and the drive of the spiral blade 304, and the waste with smaller particles falls onto the conveyor belt 310 through the through hole 303 during transportation, the second motor 501 drives the driving wheel 502 to rotate, and the driving wheel 502 drives the driven wheel 503 to rotate through the chain 504. The driven wheel 503 drives the driving roller 308 to rotate, and the driving roller 308 drives the conveyor belt 310 to move. The roller 307 and the driven roller 309 assist the conveyor belt 310 in conveying, thereby conveying the waste slag with smaller particles into the first sampling box 401, and the waste slag with larger particles is conveyed to the second sampling box 402 by the spiral blade 304. The transportation rate of the waste is adjusted by adjusting the speed of the rotor of the first motor 305, so that the waste can be screened more fully, and the dust generated during the transmission process is absorbed by the vacuum cleaner 602 to prevent air pollution.
