[0002] At present, in the production and processing of hard-shell nuts, nuts that are intact and free of impurities and have larger particles are much more expensive than broken nuts with smaller particles. Therefore, nut grading in the screening process of hard-shell nuts is very important.

[0003] When the existing material selection device for nut processing is installed and used, it cannot perform multi-stage sorting of nuts, resulting in the nuts needing to be sorted multiple times before they can be accurately sorted into appropriate size partitions; since there is no sieve hole cleaning structure, the nuts stuck in the sieve holes cannot be automatically cleaned and need to be cleaned manually by the user. Moreover, the number of nuts to be sorted is large, which puts too much burden on the user and also affects the sorting effect of other nuts, bringing certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a material selection device for nut processing. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a material selection device for nut processing, the guide plate 15 is inclined, the discharge port 5 is connected to the material selection rack 1, the guide plate 15 and the material selection rack 1 are an integrated structure, the circular protrusion 16 is close to the filter hole of the filter screen, the transmission device 7 and the transmission chain 9 are meshed, the transmission device 7 can be a transmission gear, the transmission rod 8 and the transmission device 7 are welded, a rotating groove is provided between the transmission rod 8 and the material selection rack 1, and the transmission rod 8 and the material selection rack 1 are movably connected through the rotating groove.

[0023] like Figure 1-Figure 4 As shown, the distribution of the circular protrusions 16 fits the distribution of the filter mesh inside the first screen frame 13, the first group of discharge ports 5 are located at the upper end of the first screen frame 13, the second group of discharge ports 5 are located between the first screen frame 13 and the second screen frame 14, and the third group of discharge ports 5 are located at the upper end of the lowest point of the guide plate 15. Connecting rings are provided at both ends of the spring 17, and the connecting rings have built-in threads, which are threadedly connected to the base 6 and the bottom plate 18 through threads.

[0024] It should be noted that the utility model is a material selection device for nut processing. When in use, the user puts the nuts into the material selection rack 1 through the feed port 12, and the vibration motor 2 starts to operate, driving the material selection rack 1 to vibrate at the upper end of the base 6. The six groups of springs 17 maintain the balance of the material selection rack 1, and accelerate the nut sorting process through vibration. At the same time, due to the vibration effect and the push of the first scraper 10, the nuts will gradually perform a circular motion, that is, move toward the edge of the first screen frame 13 and the second screen frame 14. Nuts of a certain size pass through the sieve holes of the two to enter the next layer, and nuts that cannot pass through the sieve holes are discharged through the discharge port 5. Nuts with smaller volumes can pass through the first screen frame 13 and the second screen frame 14 in turn, and finally enter the discharge port 5 through the guide plate 15, so that the nuts can be sorted twice.

[0025] At the same time, due to the irregular shapes of the nuts, they may get stuck in the sieve holes of the first sieve frame 13 and the second sieve frame 14. The motor 3 drives the transmission chain 9 to drive the transmission device 7, the transmission device 7 drives the transmission rod 8 to rotate, and the transmission rod 8 drives the first scraper 10 and the second scraper 11 to rotate. The first scraper 10 scrapes the nuts on the surface of the first sieve frame 13 to avoid the stacking of nuts affecting the sorting effect. At the same time, the circular protrusion 16 on the upper end of the second scraper 11 contacts the nuts stuck in the sieve holes and squeezes the nuts upward to avoid the nuts being stuck in the sieve holes.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
