Description
Technical field
The utility model belongs to the screening plant technical field, is specifically related to a kind of drum-type corn screening plant.
Background technology
Behind the harvest corn, in corn, tend to mix impurity such as stone, the grains of sand at present, influence the total quality of corn.Existing screening technique has two kinds usually: one for artificial method for screening, and it is big that this method for screening has labour intensity, cost height, inefficiency, shortcoming such as the screening cleanliness of corn is low; Two for using the method for corn screening machine, and this method in addition, because impurity is many in the corn, a large amount of dust can occur because corn screening machine complex structure causes and buys the high shortcoming of this equipment cost in screening process, influence health of operators.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and provides a kind of simple in structure, with low cost, screening precision height, labour intensity low, the drum-type corn screening plant of high efficiency and no dust pollution.
The purpose of this utility model is achieved in that and comprises support, the support top is provided with body, body upper is provided with charging aperture, be tiltedly installed with rotating two-layer screen pack formula cylinder in the housing, the filter mesh of scalping cylinder is greater than the filter mesh of dusting cover cylinder, the length of scalping cylinder is greater than the length of dusting cover cylinder, the top of scalping cylinder links to each other with charging aperture, the port of export of scalping cylinder links to each other with the big impurity outlet that is located at base inner, the port of export of dusting cover cylinder links to each other with the clean grain discharging opening that is located at base inner, base inner between dusting cover cylinder and the charging aperture is provided with thin impurity outlet, the bottom of described two-layer screen pack formula cylinder links to each other with rotary electric machine by reductor, the top of described body is provided with the dust outlet, the dust outlet links to each other with deduster by sweep-up pipe, and deduster links to each other with the dedusting fan import by airduct.
Described thin impurity outlet is at least one.
Described two-layer screen pack formula cylinder is provided with the support of band roller near a bottom portion of charging aperture.
The utility model is by arranging the big impurity outlet of two-layer screen pack formula cylinder and lower housing portion, and clean grain discharging opening and thin impurity outlet improve the screening precision of corn greatly, can make operating personnel avoid the hardship of dust pollution by the deduster that arranges; Have simple in structure, with low cost, screening precision height, labour intensity is low, the advantage of high efficiency and no dust pollution.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises support 1, support 1 top is provided with body 13, body 13 tops are provided with charging aperture 2, be tiltedly installed with rotating two-layer screen pack formula cylinder in the housing 1, the filter mesh of scalping cylinder 3 is greater than the filter mesh of dusting cover cylinder 4, the length of scalping cylinder 3 is greater than the length of dusting cover cylinder 4, the top of scalping cylinder 3 links to each other with charging aperture 2, the port of export of scalping cylinder 3 links to each other with the big impurity outlet 7 that is located at support 1 inside, the port of export of dusting cover cylinder 4 links to each other with the clean grain discharging opening 6 that is located at support 1 inside, support 1 inside between dusting cover cylinder 4 and the charging aperture 2 is provided with thin impurity outlet 5, the bottom of described two-layer screen pack formula cylinder links to each other with rotary electric machine 9 by reductor 8, the top of described body 13 is provided with dust outlet 10, dust outlet 10 links to each other with deduster 11 by sweep-up pipe 16, and deduster 11 links to each other with dedusting fan 15 imports by airduct 14.Described thin impurity outlet 5 is at least one.Described two-layer screen pack formula cylinder is provided with the support 12 of band roller near a bottom portion of charging aperture 2.
When using the utility model, unscreened corn is put into charging aperture 2, corn is owing to the gravity of self enters in the scalping cylinder 3, open rotary electric machine 9, scalping cylinder 3 and dusting cover cylinder 4 rotate simultaneously, corn exports 7 ends by charging aperture 2 ends to big impurity and advances, corn and thin impurity are entered in the dusting cover cylinder 4 by the screen pack of scalping cylinder 3, thin impurity is discharged by thin impurity outlet 5, corn enters in the clean grain discharging opening 6 through the port of export of dusting cover cylinder 4, and the big impurity of scalping cylinder 3 enters in the big impurity outlet 7 through the port of export of scalping cylinder 3; When opening rotary electric machine 9, deduster 11 is started, deduster 11 is discharged the dust in the housing 1 by dust outlet 10.Can support 1 inside between dusting cover cylinder 4 and the charging aperture 2 be provided with several impurity outlets 5 according to actual conditions, can make thin impurity be convenient to collect.The filter mesh of scalping cylinder 3 is greater than the length of corn, and the filter mesh of dusting cover cylinder 4 is less than the length of corn.
