Abstract
The utility model relates to a small-sized combine harvester, and more specifically relates to a small-sized combine harvester grain weed winnowing separator. The small-sized combine harvester grain weed winnowing separator is characterized in that: a conveying cylinder is slantingly arranged, a lower end of the conveying cylinder is connected with a threshing barrel, an upper end of the conveying cylinder is provided with a weed separating cylinder and a grain outlet, the conveying cylinder is internally provided with a conveyor belt which is driven by a driving wheel to rotate, the weed separating cylinder is provided with an air inlet and an air outlet, the air inlet of the weed separating cylinder is connected with an exhaust outlet of an internal-combustion engine of a small-sized combine harvester, and a joint of the weed separating cylinder and the conveying cylinder is provided with a wind shield. According to the small-sized combine harvester grain weed winnowing separator, exhaustion of the internal-combustion engine of the small-sized combine harvester is comprehensively utilized, energy is saved, a grain weed winnowing separating effect is good, and the separator has a promotion value.
Description
Technical field
The utility model relates to baby combine, more specifically relates to a kind of baby combine cereal weeds wind selecting separator.
Background technology
Grain header is that the crop harvesting of cereal seed such as results paddy and wheat etc. and stalk is mechanical; Be known as combine at the beginning of the fifties; It is the harvesting that can once accomplish cereal, threshing, separation cane, remove operation such as assorted excess, directly obtains the harvest machinery of grain from the field.Baby combine is the general designation of one type of lower-powered grain header in the grain header.The most selection by winnowing that adopt special-purpose fan blower to carry out the cereal weeds of the selection by winnowing separator of present small harvester are separated; Like the applying date is that 2005.07.01, application number are 200520051284.3, publication number is CN 2798547, name is called " pneumatic separation device of grain combine " disclosed technical scheme; It is place, the mouth of a valley; The top of grain transport tube is provided with the inlet scoop, and the inlet scoop links to each other with the air inlet of centrifugal blower through airduct.The selection by winnowing separator of such cereal weeds need be used special centrifugal blower, and energy consumption is higher, and the selection by winnowing separating effect is relatively poor, haves much room for improvement.
Summary of the invention
The purpose of the utility model: a kind of baby combine cereal weeds wind selecting separator is provided.
The technical scheme of the utility model is: a kind of baby combine cereal weeds wind selecting separator; It is characterized in that transport tube is obliquely installed, the lower end of transport tube is connected with threshing barrel; Be provided with weeds cylinder and grain outlet in the upper end of transport tube; In transport tube, be provided with conveyer belt, driving wheel drives conveyer belt and rotates, and on the weeds cylinder, is provided with air inlet and air outlet; The air inlet of weeds cylinder is connected with the exhaust outlet of the internal combustion engine of baby combine, is provided with deep bead at weeds cylinder and transport tube junction.
Described baby combine cereal weeds wind selecting separator, its described weeds cylinder is obliquely installed, and the air inlet of weeds cylinder is following, and the air outlet of weeds cylinder is last.
Above-mentioned described baby combine cereal weeds wind selecting separator, described deep bead is the active catch aerofoil, the angle of regulating deep bead changes the amount of keeping out the wind.
The operation principle of the utility model: the air inlet of weeds cylinder is connected with the exhaust outlet of the internal combustion engine of baby combine; Make the slit of deep bead go out to produce negative pressure; Conveyer belt in the transport tube is transported to the cereal in the threshing barrel and weeds the upper end of transport tube continuously; Cereal is discharged from grain outlet to falling under the effect of gravity, and weeds are discharged from the air outlet of weeds cylinder behind the slit entering weeds cylinder that passes under the vacuum suction of weeds cylinder between the deep bead.Regulate the vacuum magnitude of the favourable adjusting of the angle weeds cylinder of deep bead.
The baby combine cereal weeds wind selecting separator of the utility model is installed on the baby combine.
The beneficial effect of the utility model: the baby combine cereal weeds wind selecting separator of the utility model, fully utilized the exhaust of the internal combustion engine of baby combine, practiced thrift the energy, cereal weeds selection by winnowing good separating effect has promotional value.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
Through embodiment, the utility model is further described below.
Embodiment
With reference to accompanying drawing; A kind of baby combine cereal weeds wind selecting separator, transport tube 5 is obliquely installed, and the lower end of transport tube 5 is connected with threshing barrel 7; Be provided with weeds cylinder 3 and grain outlet 2 in the upper end of transport tube 5; In transport tube 5, be provided with conveyer belt 1, driving wheel 6 drives conveyer belt 1 and rotates, and on weeds cylinder 3, is provided with air inlet and air outlet; The air inlet of weeds cylinder is connected with the exhaust outlet of the internal combustion engine of baby combine, is provided with deep bead 4 in weeds cylinder 3 and transport tube 5 junctions.Described weeds cylinder 3 is obliquely installed, and the air inlet of weeds cylinder is following, and the air outlet of weeds cylinder is last.Described deep bead 4 is the active catch aerofoil, and the angle of regulating deep bead 4 changes the amount of keeping out the wind.The air inlet of weeds cylinder is connected with the exhaust outlet of the internal combustion engine of baby combine.
