Description

Technical Field

[0001] The utility model belongs to the technical field of crop selection, and in particular relates to a high-efficiency seed cleaning machine for agricultural seeds. Background Art

[0002] A seed cleaner is a device that uses the differences in shape, size, specific gravity, surface characteristics and aerodynamic characteristics of grains and inclusions to select qualified and high-quality seeds. Seed cleaning is an important link in the seed processing process. A seed cleaner can separate immature, moldy, insect-bitten, unqualified seeds and debris from good seeds among seeds with similar appearances, thereby obtaining high-quality seeds. Common gravity seed cleaners are mainly composed of a vibrating grading table, a negative pressure fan and a drive mechanism.

[0003] The existing seed cleaning machine has the problem of incomplete separation. A small amount of debris still remains between the high-quality seeds after cleaning. This is because the debris always stays with the seeds during the vibration classification and wind selection process, and a good separation effect cannot be achieved. Utility Model Content

[0008] Furthermore, a rotating shaft is installed in the impurity removal screen drum, a spiral blade is wound around the rotating shaft, a belt transmission mechanism is connected to the end of the rotating shaft, and the belt transmission mechanism is connected to a driving motor. A plurality of sieve holes are provided on the surface of the impurity removal screen drum.

[0009] Furthermore, a support frame is connected between the vibration plate and the inner wall of the device housing, a vibration generator is connected to the bottom surface of the vibration plate, and the vibration generator is electrically connected to a power supply.

[0010] Furthermore, a primary seed collection bin, a secondary seed collection bin and a debris collection bin are sequentially arranged at the bottom of the equipment housing, the primary seed collection bin is arranged on a side close to the fan, and the debris collection bin is arranged on a side away from the fan.

[0011] Furthermore, the first-level seed collecting bin is connected to a first-level seed collecting pipe, the bottom of the second-level seed collecting bin is connected to a second-level seed collecting box, and the bottom of the debris collecting bin is connected to a debris removal door.

[0012] Furthermore, an air filter is connected to the air inlet side of the fan.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] The seed cleaning machine of the utility model pre-processes sand, gravel, dust and other debris through the debris removal screen drum and the debris collection drum, collects this type of debris into the drum through the screen holes, and then performs subsequent seed selection, thereby avoiding the problem of poor separation effect of sand, gravel, dust and other debris during vibration and wind selection process. Subsequently, light debris such as weeds and leaves that cannot pass through the screen are separated again by the fan, thereby realizing two-stage separation of debris and significantly improving the effect of debris removal.
