Dust removal box 3 inside is provided with multiple sets of vibration assembly 301, and vibration assembly 301 utilizes gravitational potential energy, makes material and dust vibration and separates. Specifically, as Figure 4 shown, vibration assembly 301 includes setting in dust removal box 3 inside, transverse arrangement's horizontal plate, and horizontal plate is inclined downward arrangement. When the nut enters dust removal box 3 from the hopper 2, will fall on these horizontal plates in turn. In the process that the nut repeatedly hits horizontal plate, the dust adhered to its surface will separate from the nut under the action of vibration and impact, thereby realizing the vibration dust removal effect to the nut.

[0022] Dust removal box 3 below is placed with the negative pressure guide box 8 for collecting dust, and the slope of the front side of the negative pressure guide box 8 is provided for guiding the material. The slope of the front side of the negative pressure guide box 8 is arranged in an arc shape. When the nuts fall from the horizontal plates, they will try to hit the arc-shaped slope vertically. After the material hits the slope under the action of gravity, a filter component is provided on the slope. A negative pressure dust collection mechanism 5 is fixedly arranged inside the shell 1, and the output end of the negative pressure dust collection mechanism 5 is connected with the negative pressure guide box 8. The negative pressure dust collection mechanism 5 can provide a negative pressure environment. Under the action of airflow, the dust adhering to the surface of the nuts or having separated from the slope on the slope will be brought into the negative pressure guide box 8, thereby removing the dust and ensuring the cleanliness of the detection environment.

[0023] Further, a first conveyor belt assembly 6 and a second conveyor belt assembly 7 are arranged inside the shell 1. The first conveyor belt assembly 6 is arranged below the negative pressure guide box 8, and its main function is to receive the nuts after dust removal treatment and uniformly deliver them. The second conveyor belt assembly 7 is arranged below the first conveyor belt assembly 6, and is used to deliver the material output by the first conveyor belt assembly 6 at a high speed to a color selection mechanism (not shown in the figure). Through high-speed delivery, the nuts can be separated from each other, reducing mutual shielding and interference between the nuts, thereby reducing the detection difficulty and improving the accuracy and efficiency of color selection.

[0024] In an alternative embodiment, a dust suction cavity 302 is arranged at the middle position of the rear side of the dust removal box 3, and a filter plate 303 is arranged at the front side of the dust suction cavity 302, and the filter plate 303 is located between the two groups of horizontal plates, as Figure 4The dust collection cavity 302 is connected with the output end of the negative pressure dust collection mechanism 5. The dust collection structure arranged in the middle of the dust removal box 3 can more effectively collect the dust generated in the dust removal process, and the whole realizes twice dust collection operation, thereby improving the overall dust collection effect.

[0025] In another alternative embodiment, the lower end of the dust removal box 3 is fixedly provided with a rotating shaft 304, the rotating shaft 304 is rotatably arranged at both ends of the shell 1, and the upper end of the dust removal box 3 is provided with a vibrating mechanism 4 for driving the dust removal box 3 to vibrate.

In use, the vibrating block 401 drives the dust removal box 3 to vibrate, one end of the dust removal box 3 moves along the axis of the rotating shaft 304, and the position is maintained. The spring 403 can ensure that the dust removal box 3 can be reset in time after vibration, so as to prepare for the next vibration, thereby ensuring continuous and stable vibration effect and improving dust removal efficiency. In addition, the distance between the front side wall and the rear side wall of the dust collection box is less than three times the diameter of the material, so as to avoid too much material being discharged at one time and prevent the nuts from being accumulated to cause insufficient dust removal.

[0026] In another alternative embodiment, the negative pressure dust collection mechanism 5 includes a negative pressure device 501 fixedly arranged on the inner side of the shell 1, a first dust collection pipe 502 in cooperation with the negative pressure guide box 8 and a second dust collection pipe 503 in cooperation with the dust collection cavity 302 are arranged on the negative pressure device 501. Through the arrangement of the two dust collection pipes, the negative pressure device 501 can simultaneously suck the dust in the negative pressure guide box 8 and the dust collection cavity 302, forming a complete dust collection system and further improving the dust collection efficiency.

[0027] Working principle: the nuts fall from the feeding hopper 2, and move downwards along the feeding hopper 2. The nuts enter the dust removal box 3 arranged in cooperation with the shell 1 from the lower end of the feeding hopper 2. The dust removal box 3 is internally provided with multiple groups of transverse plates. The nuts fall onto these transverse plates in turn, and under the action of gravity, the nuts collide with the transverse plates multiple times. By using the gravitational potential energy, the dust on the surface of the nuts is separated from the nuts under the action of vibration and impact. The vibrating block 401 drives the dust removal box 3 to vibrate. One end of the dust removal box 3 moves along the axis of the rotating shaft 304, while the spring 403 between the fixed plate 402 and the dust removal box 3 ensures that the dust removal box 3 is reset in time after vibration, and the vibrating block 401 is started, which can improve the vibration effect of the nuts. The dust collection cavity 302 is connected with the output end of the negative pressure dust collection mechanism 3. The dust collection structure arranged in the middle of the dust removal box 3 can more effectively collects the dust generated in the dust removal process, and the whole realizes twice dust collection operation, thereby improves the overall dust collection effect.

[0028] The nuts after the vibration dedusting drop from the horizontal plate, vertically impact on the arc-shaped slope surface arranged in front of the negative pressure guide box 8 below the dedusting box 3. The dust adhered to the surface of the nuts or separated from the slope surface is taken into the negative pressure guide box 8 under the action of the airflow, and the nuts are dedusted again, so that the detection environment is ensured to be clean.

[0029] The nuts after the sufficient dedusting fall on the first conveying belt assembly 6, and the first conveying belt assembly 6 conveys the nuts to the second conveying belt assembly 7 arranged below. The second conveying belt assembly 7 runs at a high speed, and conveys the materials output by the first conveying belt assembly 6 at a high speed to the color selection mechanism. During the high-speed conveying process, the nuts are separated from each other, the mutual shielding and interference between the nuts are reduced, and the detection difficulty is reduced.
