Abstract
The utility model discloses a cylindrical precleaner case with a winnowing and impurity eliminating device. A grain inlet is formed in the side edge of the upper end of the case, an inner-layer straight cylindrical screening drum and an outer-layer straight cylindrical screening drum are installed in the middle of the case, a large impurity outlet is formed in the front end of the bottom of the case, and a small impurity outlet is formed in the middle of the case. A grain outlet is formed between the large impurity outlet and the small impurity outlet, the winnowing and impurity eliminating device is installed on one side edge of the grain outlet and is a fan, the fan directly faces the side edge of the grain outlet, and an air outlet is formed in the other side edge of the grain outlet. An air volume regulation plate is arranged on the portion, on the air outlet of the fan, of the winnowing and impurity eliminating device and can control air volume. The winnowing and impurity eliminating device is installed on the grain outlet in the lower end of the cylindrical precleaner case so that light impurities can be eliminated in the process of primary screening of grains, the original structure is hardly changed, the cost is low, and the effect is remarkable.
Description
technical field:
The utility model relates to grain processing equipment field, relates in particular to a kind of cylindrical pre-cleaning screen housing with Winnowing impurity-cleaning device.
background technology:
Cylindrical pre-cleaning screen is applicable to the slubbing cleaning of raw grain, adopts straight cylinder screen drum, the large small impurities in separable raw grain, and screen drum tilts to install, and angle is adjustable.TCQY series cylindrical pre-cleaning screen has inside and outside two-layer screen drum, utilizes the different of grain and impurity size, by the continuous rotation of screen drum, the thin impurity that is greater than the large impurity of interior screen-aperture and is less than outer screen-aperture is separated to clear effect at the beginning of reaching in raw grain.The front end of screen drum supports rotation by two support rollers, and rear end is connected by universal cross coupler and main shaft, in the time that support roller is adjusted inclination angle up and down, due to the effect of Hooks coupling universal coupling, guarantees that screen drum can rotate freely.The adjustment at screen drum inclination angle, can change the gliding speed of material in screen drum, thereby changes productivity ratio.This sieve series height, assorted clearly effective, screen drum is by front and back rolling disc and band steel seam, and sieve is made up of cold drawing punching, with the fixing composition of bolt screen drum.Slot size is selected according to the different grain of screening.Power section selects cycloidal planetary gear speed reducer to slow down, and chain drive, has compact conformation, stable drive, the advantage that noise is little.
But find in process of production, in the raw grain after screening, inevitably, with light skin grain husk shell, dust, snow frost etc., drop with raw grain, remove these impurity also needs to increase a procedure, very inconvenient.Therefore imagination provides a kind of equipment to solve this problem.
utility model content:
The purpose of this utility model is just to provide a kind of cylindrical pre-cleaning screen housing with Winnowing impurity-cleaning device, solve but find in process of production, in raw grain after screening, inevitably with light skin grain husk shell, dust, snow frost etc., drop with raw grain, remove these impurity and also need to increase a procedure, very inconvenient problem.
The technical solution adopted in the utility model is:
A kind of cylindrical pre-cleaning screen housing with Winnowing impurity-cleaning device: housing upper end side is provided with grain inlet, housing middle part has installs inside and outside double-deck straight cylinder screen drum, housing bottom front end is provided with large assorted outlet, middle part is provided with little assorted outlet, between large assorted outlet and little assorted outlet, be provided with grain outlet, grain outlet side is provided with Winnowing impurity-cleaning device, and described Winnowing impurity-cleaning device is a blower fan, blower fan is the side to grain outlet just, and another side of grain outlet is provided with air outlet.
Described Winnowing impurity-cleaning device is also provided with air quantity adjustment disk at fan outlet place, can control air force.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by the structure of Winnowing impurity-cleaning device is installed at grain outlet place, cylindrical pre-cleaning screen housing lower end, can be removed light weight sundries in primary election grain, and original structure is not almost changed, and cost is low, and effect is remarkable.
accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model side view.
the specific embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
A kind of cylindrical pre-cleaning screen housing with Winnowing impurity-cleaning device: housing 1 upper end side is provided with grain inlet 2, housing 1 middle part has installs inside and outside double-deck straight cylinder screen drum, housing 1 bottom front is provided with large assorted outlet 3, middle part is provided with little assorted outlet 5, between large assorted outlet 3 and little assorted outlet 5, be provided with grain outlet 4, grain outlet 4 sides are provided with Winnowing impurity-cleaning device, and described Winnowing impurity-cleaning device is a blower fan 6, blower fan 6 is the side to grain outlet 4 just, and grain outlet 4 another sides are provided with air outlet 7; Winnowing impurity-cleaning device is also provided with air quantity adjustment disk at fan outlet place, can control air force.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, the utility model can also have other implementations.It should be noted that, do not departing under the prerequisite of the utility model design, within any apparent improvement and modification all should fall into protection domain of the present utility model.
