Detailed Description

The invention is further explained with reference to the drawings and the embodiments.

Referring to fig. 1, the multi-stage rice impurity removing and screening apparatus includes a box 1, a first screening chamber 2, a second screening chamber 3, a feeding port 4, a blower 5, a first discharging port 6, a first sieve plate 7, a first dust outlet 8, a second sieve plate 9, a second dust outlet 10, and a second discharging port 11. The feeding hole 4 is arranged on one side of the upper end of the box body 1, the first screening cavity 2 is arranged right below the feeding hole 4, the right side of the first screening cavity is provided with a blast hole and a first discharging hole 6, the left side of the first screening cavity is provided with a first dust outlet 8, and the bottom of the first screening cavity is provided with a first screening plate 7; a second screening chamber 2 is arranged below the first screening plate 7, a blast port and a second discharge port 11 are fixedly arranged on the right side of the second screening plate 9, and a second dust outlet 10 is arranged on the left side of the second screening chamber 2; the blast port is provided with a blower 5, the first dust outlet 8 and the second dust outlet 10 are both connected with a dust collecting box 14, and the first discharge port 6 and the second discharge port 11 are both connected with a discharging chute 15.

In this embodiment, the lower terminal surface of box is provided with U style of calligraphy structure, and U style of calligraphy structure bottom is equipped with the third discharge gate, and the rice that passes through the second sieve is because the radian design of gravity and U type, and the third discharge gate falls automatically.

In this embodiment, first sieve 7 and second sieve 9 all incline and bottom fixedly connected with vibrating motor to the below right, and the rice falls into the sieve from the upper left side on, moves to below right through the vibrating motor effect, until reaching the discharge gate.

In this embodiment, the first sieve 7 and the second sieve 9 are filter screens, and the aperture of the filter screen of the first sieve is larger than that of the second sieve. Big granule's rice is followed first discharge gate roll-off, and the rice of less granule drops to the second sieve and continues to divide the sieve, and less granule rice falls into the third discharge gate.

In this embodiment, the ground of the bottom of unloading spout 15 and third discharge gate below all is equipped with and connects workbin 13, makes things convenient for the staff to observe the rice condition after the branch sieve at any time, also is convenient for carry.

In this embodiment, the dust collecting box is detachably connected with the box body, and the dust collecting box 14 is taken down and cleaned by workers after the screening and impurity removing work is finished.

In this embodiment, the feed inlet is provided with a discharge pipe.

Furthermore, the support column is fixedly connected to the lower portion of the box body and fixed to the ground.

The working principle is as follows:

during the use, at first start vibrating motor and air-blower, put into the unloading pipe with the rice that contains impurity again for form horizontal air current in first screening cavity and the second screening cavity. The rice falls onto the first sieve plate through the feeding hole, under the action of the vibration motor, clean large-particle rice falls into the material receiving box 13 from the first discharging hole through the chute, small-particle rice falls onto the second sieve plate, and meanwhile, small-particle dust contained in the falling rice is blown to the first dust outlet 8 through the air blower, so that primary screening and impurity removal are completed; the rice that drops on the second sieve is like through the effect of vibrating motor and air-blower, further blows off light impurity, and the broken rice of littleer granule and partial solid impurity shake and fall to the bottom half, discharge from the third discharge gate.

The present invention is not limited to the above embodiments, and various combinations and modifications of the above technical features may be provided for those skilled in the art, and modifications, variations, equivalents, or uses of the structure or method of the present invention in other fields without departing from the spirit and scope of the present invention are included in the protection scope of the present invention.
