[0026] Working principle: After the materials are put into the feeding hopper 1, the materials are conveyed by the auger 2, discharged from the upper end of the auger 2 and then fall into the feeding hopper 3 of the sheller. The materials slide into the feeding port of the sheller head one 4 from the feeding hopper 3 of the sheller, and after the shelling is performed by impact inside, the materials are discharged from the lower end of the sheller head one 4 and then fall into the skin-seed kernel sorting machine one 6. The shelled materials include part of unshelled melon seeds, half-shelled melon seeds, melon seed skins, melon kernels and a small amount of broken kernels.
[0027] The skin-seed kernel sorting machine one 6 has a layer of sieve pieces. After the shelled materials are vibrated, screened and conveyed, the materials are divided into two categories: one category is unshelled melon seeds and large melon seed skins, and the other category is melon kernels, broken kernels and fine melon seed skins. The unshelled melon seeds and the large melon seed skins are above the sieve pieces, conveyed by vibration and discharged from the lower end of the pipe 9 cover. The fan 8 draws air from the pipe 9 cover to form a negative pressure, and the large melon seed skins in the materials are taken away and discharged through the pipe 9 and the fan 8. The unshelled melon seeds are discharged from the discharge end of the skin-seed kernel sorting machine one 6 and then fall into the seed kernel sorting machine one 7. The melon kernels, broken kernels and fine melon seed skins are below the sieve pieces, conveyed by vibration and discharged from the side discharge port of the skin-seed kernel sorting machine one 6 and then fall into the side feeding port of the seed kernel sorting machine one 7.
[0028] The seed kernel sorting machine one 7 has a layer of sieve pieces. The unshelled melon seeds fall into the seed kernel sorting machine one 7 from the feeding end, discharged from the discharge end and then fall into the feeding port of the sheller head two 16 after being vibrated, screened and conveyed. The melon kernels, broken kernels and fine melon seed skins enter the sieve pieces below from the side feeding port of the conveying starting end, conveyed by vibration and discharged from the side discharge port of the conveying ending end and then fall into the feeding port above the chute 15, and finally discharged from the lower end of the chute 15 and then fall into the side feeding port of the middle section of the seed kernel sorting machine two 14.
[0029] The unshelled melon seeds fall into the feeding port of the sheller head two 16, and after the shelling is performed by impact inside, the unshelled melon seeds are discharged from the lower end of the sheller head two 16 and then fall into the skin-seed kernel sorting machine two 13. The shelled materials include part of unshelled melon seeds, half-shelled melon seeds, melon seed skins, melon kernels and a small amount of broken kernels.
[0030] The seed kernel sorting machine two 13 has a layer of sieve pieces, and the materials after shelling are divided into two categories after passing through the vibrating screen and conveying: one category is the unshelled watermelon seeds and larger watermelon seed skins; the other category is watermelon kernels, broken kernels and small watermelon seed skins. The unshelled watermelon seeds and larger watermelon seed skins are above the sieve pieces and pass through the lower part of the pipe 9 end cover through vibrating conveying. The fan 8 draws air from the pipe 9 end cover to form a negative pressure, and carries away the larger watermelon seed skins in the materials, which are discharged through the pipe 9 and the fan 8. The unshelled watermelon seeds are discharged from the discharge end of the seed kernel sorting machine two 13 and fall into the seed kernel sorting machine two 14 feeding end; the watermelon kernels, broken kernels and small watermelon seed skins are below the sieve pieces and are discharged from the side discharge port of the seed kernel sorting machine two 13 and fall into the side feeding port of the conveying starting end of the seed kernel sorting machine two 14.
[0031] The seed kernel sorting machine two 14 has a layer of sieve pieces and a short sieve section, and the unshelled watermelon seeds fall from the feeding end, pass through the sieve pieces after vibrating screening and conveying, and are discharged from the discharge end and fall into the upper hopper 1. The watermelon kernels, broken kernels and small watermelon seed skins enter the sieve pieces below the side feeding port of the conveying starting end, pass through vibrating conveying, reach the sieve pieces of the short sieve section, and then vibrate and screen and convey on the sieve pieces of the short sieve section together with the materials falling from the side feeding port of the middle section. The watermelon kernels pass through vibrating conveying on the sieve surface of the short sieve section, are discharged from the side discharge port of the conveying end of the seed kernel sorting machine two 14, and enter the next process. The broken kernels and small watermelon seed skins pass through vibrating conveying below the sieve surface of the short sieve section and are discharged from the side discharge port of the conveying end of the short sieve section. Through the above technical scheme, the purposes of improving the yield of the watermelon seed shelling machine group, improving the fine classification efficiency of the shelled materials and reducing the breakage rate of the watermelon kernels during secondary shelling are achieved.
