Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

A maize seed double entry cleaning plant as shown in fig. 1 ~ 3 comprises bottom plate 1, cushion rubber callus on the sole 2, dustcoat 3, hopper 4, vibrating motor 5, vibration tray 6, dead lever 7, one-level spiral 8, proportion sieve dish 9, wind dish 10, intake pipe 11, blast pipe 12, diverter plate 13, second grade spiral 14, one-level dish 15, second grade dish 16, tertiary dish 17, one-level hopper 18, second grade hopper 19 and tertiary hopper 20. The whole structure is divided into three parts, namely a shell fixing device, a vibrating device and a spiral multi-structure screening device.

The shell fixing device consists of a bottom plate 1 and an outer cover 3, and the whole structure of the compound corn seed cleaning and sorting machine is cylindrical, so that the outer cover 3 is of a cylindrical barreled structure. Be equipped with the cushion gum callus on the sole 3 between bottom plate 1 and dustcoat 3, the cushion gum callus on the sole specifically is the damping rubber ring, adds damping spring and the rubber ring inside that is equipped with high strength, can effectually prevent the vibration of dustcoat 3 in the course of the work, improves the stability of maize seed double entry cleaner.

As shown in fig. 2, the power source of the vibration device is a vibration motor 5, which is mounted on the bottom plate 1, the output end of the vibration motor 5 is provided with a vibration tray 6, and the vibration tray 6 is located in the outer cover 3 and cannot be separated from the outer cover 3 in the vibration process. The fixed rod 7 is fixed to the position installation between two parties of the vibration tray 6, and the upper end position of fixed rod 7 is installed at the top of the housing 3, and at the vibration motor 5 in-process from top to bottom, the tray 6 vibrates with the fixed rod 7 from top to bottom in step, and because the limiting displacement of the housing 3, the tray 6 and the fixed rod 7 can not produce the swing of horizontal direction. The stability of the entire structure becomes high.

As shown in fig. 3, the spiral type multi-structure sieving apparatus is mounted on the fixing bar 7, and the spiral type multi-structure sieving apparatus is divided into a primary spiral 8 and a secondary spiral 14 from the top. The primary screw 8 is of a double-layer structure, the primary screw 8 integrates proportion screening and winnowing, the upper layer space is a proportion screening tray 9, and the lower layer space is an air tray 10. The working principle of the specific gravity screening is that the materials generate specific gravity segregation under the dual action of aerodynamic force and vibration friction force, and the materials with larger specific gravity sink to the bottom by adjusting technical parameters such as wind pressure, amplitude and the like and move from low to high by adhering to a screen surface, and the materials with smaller specific gravity suspend on the surface and move from high to low, so that the purpose of specific gravity separation is achieved. Therefore, the bottom surface of the gravity screen is provided with an inclination angle, generally a longitudinal inclination angle and a transverse inclination angle. The corn seed compound cleaning and sorting machine adopts a spiral structure, the inclination angle is formed by self in the longitudinal direction and is 10-20 degrees in the transverse direction, namely the spiral bottom surface of a specific gravity sieve tray 9 of a primary spiral 8 inclines 10-20 degrees to the center, as shown in figure 4. The bottom surface of the specific gravity sieve tray 9 is provided with an air hole 1001 structure, and because the pipe orifice diameter of the air inlet pipe 11 arranged at the lower end of the air tray 10 is larger than the pipe orifice diameter of the exhaust pipe 12, an air flow discharge difference is formed, and air flow in the air tray 10 can flow into the specific gravity sieve tray 9 through the air hole 1001. The aperture of the air hole 1001 is 0.5 mm-1 mm, so that the corn seed is prevented from blocking the air hole 1001. During operation, one-level spiral 8 is under the reciprocating vibration effect, and the maize seed that drops to specific gravity sieve dish 9 from hopper 4 carries out the layering in the quotation, through outside fan to 11 gas injections of intake pipe, under the effect of air current, the layering has been carried out to the seed in the quotation, and heavier seed is in the below, and blade and flat grain fall on the top. The motion tracks of the two are different, so that the purpose of screening is achieved. The primary screw 8 removes some of the lighter impurities such as skin chips, barks, etc.
