Peanut kernel color sorting device

Abstract

The utility model provides a peanut kernel color sorting device which solves the problems that due to the fact that too many peanut kernels passing through a screening device are overlapped, the screening effect of the peanut kernels is poor, and secondary screening is needed. The first rotating drum and the soft bristles are arranged in the conveying hopper, peanut kernels can be flatly laid into one layer, and the situation that defective peanut kernels and non-defective peanut kernels are blown out together by a high-speed spray valve or the defective peanut kernels are blocked by the non-defective peanut kernels and cannot be effectively screened out when the peanut kernels pass through the right end of the conveying hopper due to the fact that the number of overlapped layers is too large is avoided. And meanwhile, the first rotating drum is rotationally arranged, so that the first rotating drum and the soft bristles can automatically rotate when the peanut kernels are too much, and the peanut kernels are prevented from being blocked or blocked between the first rotating drum and the conveying hopper.

Description

Technical Field

[0001] The utility model relates to the technical field of peanut screening, in particular to a peanut kernel color sorting device. Background Art

[0002] Peanuts, formerly known as groundnuts, are a kind of nut with abundant production and wide use in my country. They are also known as "longevity nuts". They are rich in nutrients, can promote human metabolism, enhance memory, improve intelligence, resist aging, and prolong life. There are many processing methods for peanuts. After peanuts are sorted according to particle size, it is usually necessary to distinguish and screen the good and bad peanuts. According to the different weights of peanut kernels, when using a color sorter, the moldy or deteriorated peanut kernels are separated and the peanut kernels are screened. The working principle of the color sorting machine is to use photoelectric detection technology to automatically sort out the different-colored particles in the particles according to the differences in the optical properties of the particles. The image acquisition system collects the images of the passing particles, observes and displays the pictures of the particles to be sorted, and performs relevant image data analysis and sorting to obtain the discrimination results, which are transmitted to the actuator high-speed spray valve to achieve particle sorting.

[0003] However, when the peanut kernels passing through the screening device overlap too much, the peanut kernel screening effect will be poor. The high-speed spray valve will blow out the defective peanut kernels together with the good peanut kernels, or the defective peanut kernels will be blocked by the good peanut kernels and cannot be effectively screened out, requiring secondary screening.

[0027] A rotating drum 45 is rotatably provided in the feed hopper 41, and soft bristles 44 are fixedly provided on the outer peripheral surface of the rotating drum 45. The rotating drum 45 is located on the left side of the rotating drum 1 43, and the horizontal height of the rotating drum 45 is higher than that of the rotating drum 1 43. The rotating drum 45 located on the rotating drum 1 43 can block the excessive accumulation of peanut kernels, avoid the accumulation of peanut kernels, and further spread the peanut kernels evenly.

[0033] Working principle: When in use, the peanut kernels enter the inner left end of the feed hopper 41 through the barrel 47, and move to the right under the vibration effect of the vibration motor. The rotating drum 2 45 blocks the peanut kernels that accumulate too high, and the rotating drum 1 43 can further spread the overlapping multiple layers of peanut kernels into a layer and convey them along the chute. The peanut kernels are conveyed to the color sorting device 21 through the feed hopper 22. The color sorting device 21 sorts the peanut kernels into defective and good products. The defective peanut kernels are discharged through the discharge hopper 1 23, and the good peanut kernels are discharged through the discharge hopper 2 24 onto the conveyor belt 5. The complete peanut kernels are blocked by the V-shaped baffle 7, move along the inclined direction of the V-shaped baffle 7 and fall into the collecting box 2 9 for collection, and the half peanut kernels fall into the collecting box 1 8 through the gap between the V-shaped baffle 7 and the conveyor belt 5.
