Description

Technical Field

[0001] The invention relates to the technical field of potato breeding, in particular to a device for conveying and removing impurities from potato original seeds. Background Art

[0002] The original stock is the seed potato produced at the beginning of the transplanting or cutting period of virus-free test tube seedlings.

[0003] When harvesting the original seeds cultivated in substrate, workers need to manually shake the original seeds off the rhizomes into the substrate in the culture tray, and then pour the original seeds and substrate in the seedling tray into a screening device for separation.

[0004] Patent number CN211831914U discloses a potato seed harvester, including a support frame, a buffer assembly fixed on the top of the support frame, a chute arranged obliquely fixed on the top of the buffer assembly, a vibrator installed at the bottom of the chute, a screen net fixed at the middle of the inner side of the chute, a hopper arranged at the top of the chute inclined upward, a seed discharge port arranged at the upper part of the chute inclined downward, and a matrix main discharge port arranged at the bottom of the chute inclined downward. The utility model has a simple structure, and the potato seed and growth matrix mixture in the chute are separated, and flow out from different outlets for bagging, which can realize continuous operation, greatly improve the harvesting speed of potato seed, and realize the full harvesting of seed without omission.

[0005] The above device can only separate the matrix from the potato original seeds by screening, but there are usually rhizomes remaining in the matrix. Although the matrix mixed with the potato original seeds can pass through the sieve net in the equipment, the rhizomes remaining in the matrix continue to be mixed with the original seeds and move along the sieve net. Workers are required to manually pick out the rhizomes mixed in the original seeds, and the above device cannot clean the outer skin of the potato original seeds. After screening, some of the matrix will adhere to the outer skin of the potato original seeds. The matrix may contain pathogens or insect eggs, which may increase the risk of disease during planting. In addition, the matrix may absorb moisture, resulting in a moist surface of the original seeds, which is not conducive to storage and increases the possibility of rotting. Summary of the invention

[0033] Embodiment 2: Based on embodiment 1, Figure 3 and Figure 4 As shown, the shaking preliminary screening mechanism includes a shaking screening shovel plate 302, a moving block 3022 and a fixed round rod 3042. The shaking screening shovel plate 302 is fixedly connected to the sliding block 3021. The bottom surface of the shaking screening shovel plate 302 fits with the inner bottom surface of the picking frame 1. A through hole is provided on the shaking screening shovel plate 302. The sliding block 3021 at the right end is fixedly connected with a moving block 3022. A wavy groove is provided in the moving block 3022. The right end of the lower roller 3041 is fixedly connected to the fixed round rod 3042. The fixed round rod 3042 is located in the wavy groove on the moving block 3022. When the lower roller 3041 rotates, the moving block 3022 is driven to slide left and right through the fixed round rod 3042, and then the shaking screening shovel plate 302 is driven to shake left and right through the sliding block 3021 to perform preliminary screening of the potato original seed and the matrix.

[0034] When the lower roller 3041 rotates, it pushes the moving block 3022 to move left and right through the fixed round rod 3042, thereby driving the sliding block 3021 to slide left and right along the lower roller 3041.

In the process of the shaking screening shovel 302 shaking left and right, the potato original seeds in the matrix can be screened out. As the moving frame 2 and the electric slider 203 continue to slide along the electric guide groove 101, the potato original seeds screened out by the shaking screening shovel 302 fall into the conveyor belt 304, thereby realizing the function of preliminary screening of the potato original seeds in the matrix.

[0035] like Figure 5-Figure 8 As shown, the conveying and cleaning mechanism includes a first auger 305, a sliding cleaning brush 306, a sliding rod 307, a second belt drive group 308, a bevel gear drive group 309 and a swinging jet assembly. The first auger 305 is rotatably connected in the mobile frame 2, and the first auger 305 is located in the conveying frame 3. The potato original seeds sent into the conveying frame 3 by the conveyor belt 304 are pushed into the mobile frame 2 by the first auger 305. The conveying frame 3 is slidably connected with the sliding cleaning brush 306 and the sliding rod 307, and the sliding rod 307 is fixedly connected to the sliding cleaning brush 306. The second auger 402 drives the first auger 305 to rotate through the second belt drive group 308 and the bevel gear drive group 309. The swinging jet assembly is located in the mobile frame 2, and the swinging jet assembly blows off the residual matrix in the potato original seeds entering the mobile frame 2.

[0036] When the power shaft 4 rotates, it drives the second auger 402 to rotate, and the second auger 402 drives the first auger 305 to rotate through the second belt drive group 308 and the bevel gear drive group 309. The two first augers 305 in the conveying frame 3 rotate in opposite directions, so as to respectively convey the potato original seeds to the moving frames 2 at both ends of the conveying frame 3, and in the process of the first auger 305 driving the potato original seeds to move in the conveying frame 3, the potato original seeds contact the sliding cleaning brush 306 in the conveying frame 3, and the sliding cleaning brush 306 sweeps away the matrix remaining on the surface of the potato original seeds. When the potato original seeds are delivered to the moving frame 2 and fall on the receiving plate 401, the swing jet assembly blows air to the potato original seeds on the receiving plate 401, and uses a high-speed airflow to blow away the matrix and roots remaining on the surface of the potato original seeds, and the blown-off matrix and roots fall from the through holes of the receiving plate 401.

During the sliding frame 503 sliding back and forth along the guide frame 502, the sliding frame 503 drives the rotating block 504 to rotate forward and reverse continuously through the arc convex strip, and then drives the air injection pipe 501 to swing left and right through the air inlet pipe 5, so as to blow away the matrix in the potato original seed in the movable frame 2.

[0038] Before collecting the potato original seeds, the external blower outlet is connected to the air inlet pipe 5. When the power shaft 4 rotates, it drives the rotating block 403 to rotate. When the rotating block 403 rotates, the sliding frame 503 is driven by the wavy guide groove inside the rotating block 403 to slide back and forth along the guide frame 502. When the sliding frame 503 slides along the guide frame 502, it drives the rotating block 504 to rotate back and forth, thereby driving the air inlet pipe 5 and the air jet pipe 501 to swing back and forth. The airflow entering the air inlet pipe 5 through the blower is ejected outward from the air jet pipe 501, and the high-speed airflow contacts the potato original seeds on the receiving plate 401 and blows away the matrix and roots remaining on the surface of the potato original seeds, thereby realizing the function of removing impurities in the process of conveying the potato original seeds.

[0040] When the rotating block 504 drives the air intake pipe 5 to rotate, the swing link 3072 on the air intake pipe 5 swings accordingly. During the reciprocating swing of the swing link 3072, the sliding rod 307 is driven to slide back and forth along the conveying frame 3 through the fixed plate 3071, and the sliding cleaning brush 306 slides back and forth accordingly. During the process of the first auger 305 conveying the potato seed, the sliding cleaning brush 306 moves back and forth to clean the surface of the potato seed.

[0044] When the upper roller 3043 rotates, it drives the connecting shaft 7 to rotate through the first belt transmission group 3044. When the connecting shaft 7 rotates, the fixed push block 701 moves accordingly. During the movement of the fixed push block 701, it drives the swing rod 702 to swing. During the swinging of the swing rod 702, it drives the sliding cleaning frame 703 to slide back and forth in the moving frame 2. When the sliding cleaning frame 703 slides, it pushes away the roots entangled in the outer lever of the rotating cleaning wheel 601 through the wedge block 704.
