Abstract

An air adjusting type vibration winnowing screen solves the problems of poor adaptability and winnowing effect of an existing vibration winnowing screen. The air adjusting type vibration winnowing screen comprises a screen body, the screen body is mounted on a framework by the aid of an elastic part, electric vibration exciters are mounted on two sides of the screen body respectively, a material conveying plate and a winnowing plate are disposed in the screen body, and a screen cover is mounted on the upper portion of the screen body. The air adjusting type vibration winnowing screen is characterized in that an air adjusting plate is mounted at an air inlet of the screen body. The air adjusting type vibration winnowing screen has the advantages that air flow velocity and flow rate are changed since the air inlet can be adjusted by changing angles of the air adjusting plate, winnowing efficiency is improved and accordingly production yield is increased. Furthermore, winnowing effect of materials is improved, such as buckwheat, content of kernels in buckwheat shells is lower than or equal to 1%, content of shells in the kernels is 0.02%, and nearly no shells are mixed in the kernels. In addition, the air adjusting type vibration winnowing screen is wider in application range, is multipurpose and suitable for removal of shells, impurities and shriveled kernels of various materials including buckwheat, sunflower seeds, pumpkin seeds, pearl barleys, silybum marianums after being shelled.

Description

The air regulating type Vibration wind riddle

Technical field

The utility model belongs to a kind of agricultural product sorting and impurity-removing device, particularly a kind of air regulating type Vibration wind riddle.

Background technology

In the process of agricultural product, to carry out the sorting removal of impurities to the material after the shelling usually and handle, remove impurity wherein, to guarantee the quality of product.In the prior art, the crops sorting unit has many kinds, but all can not obtain gratifying separating effect.Chinese patent CN2493309Y discloses a kind of " Vibration wind riddle ", and it mainly is made up of sorting casing, frame, electric activator, flexible member and wind-force separator etc.The sorting casing comprises sieve nest and sieve lid, on sieve nest, also has sorting plate and mass transport plate, and the front end of sorting plate and mass transport plate is positioned at the top that air inlet is a blanking port.When material when the mass transport plate falls, full material does not receive windage, falls from blanking port; Light impurity is then directly taken away by wind, and not full material and heavier impurity are taken on the sorting plate by wind-force, when the front end of sorting plate falls; Exchange with wind once more, carry out sorting repeatedly.The subject matter that this patent exists is, because the size of wind-force is not easy to adjustment, thereby changes when the kind of material, and when perhaps inlet amount changed, separating effect was not good, can influence each item index, thereby influenced the quality of product.

Summary of the invention

The technical problem that the utility model will solve is, overcomes existing Vibration wind riddle bad adaptability, the not good problem of separating effect, provides that a kind of scope of application is wide, the air regulating type Vibration wind riddle of good separation effect.

The utility model has a sieve nest, and sieve nest is installed on the frame through flexible member, is separately installed with electric activator in the both sides of sieve nest; Mass transport plate and sorting plate are arranged in sieve nest; The sieve lid is installed on the top of sieve nest, and its special character is at the air inlet place of sieve nest air regulating board to be installed; Through the flow velocity and the flow of air regulating board adjusting wind, to improve separating effect.

Described air regulating board is fixed in the rotating shaft, and rotating shaft is installed on the sieve nest, at an end of rotating shaft the adjusting device of controlling air regulating board is installed.

Described adjusting device comprises handle, handle and securing member, and handle and securing member are installed in the rotating shaft, and handle is installed in the end of handle, through handle and handle rotating shaft is rotated, and then regulates the angle of air regulating board.

The advantage of the utility model is:

1, at the air inlet place of sieve nest air regulating board is installed,, adjusts the size of air inlet, changed the flow velocity and the flow of wind, improved the efficiency of separation, thereby improved output through changing the angle of air regulating board.

2, improved the effect of sorting material, for example buckwheat contains benevolence≤1% in the skin, contains skin 0.02% in the benevolence, contains skin hardly.

3, the scope of application is wideer, is suitable for removing cot, light assorted and flat seed after the shelling of more kinds of materials, like buckwheat, sunflower, pumpkin seeds, the seed of Job's tears, milk thistle etc., a tractor serves several purposes.
