Abstract
The utility model discloses a cleaning system and a cyclone separation barrel applied to the same. The cyclone separation barrel comprises a barrel body, wherein the middle section of the barrel body is a cylinder section, and the upper and lower sections of the barrel body are cone sections; a separation pipeline extending in the radial direction and used for being communicated with a winnower is communicated with the cylinder section; and the side wall of the separation pipeline, which is far away from an axis of the barrel body protrudes from the barrel wall of the cylinder section of the barrel body. Therefore, the materials to be cleaned are guaranteed to be far away from the position of the axis of the barrel body as far as possible when fed into the cyclone separation barrel, the amount of grains sucked by an impurity suction fan is reduced, and the cleaning loss can be lowered without the increment of the diameter of the barrel body.
Description
Technical field
The utility model relates to a kind of cyclonic separation cleaning and sorting system of grain combine, is specifically related to the cyclone separating tube of cyclonic separation cleaning and sorting system.
Background technology
Cleaning and sorting system is the important component part of grain combine, and the quality of its performance directly has influence on the operation effectiveness of complete machine.At present, on most of grain combines, the mode of cleaning that extensively adopts blower fan to match with vibratory sieve.But,,, should not dispose bulky " blower fan-vibratory sieve " cleaning and sorting system owing to receive the restriction of power and locus for the miniature grain combine of hilly and mountainous land.Consider that miniature grain combine feed quantity is less, cleaning operation with cyclonic separation cleaning and sorting system completion simple and compact for structure, reliable operation is more reasonably to select.
Existing cyclonic separation cleaning and sorting system mainly is made up of winnow, the pipeline of winnowing, cyclone separating tube, impurity adsorbing blower and gettering pipeline; The cylindrical shell of cyclone separating tube is a both ends open structure up and down; The lower ending opening of cylindrical shell is the mouth of putting out cereal, and an end of said gettering pipeline links to each other with the sealing of the open upper end of cyclone separating tube, the other end links to each other with the gettering mouth sealing of said impurity adsorbing blower.The epimere of said cylindrical shell is that up-small and down-big cone segments, interlude is that column body segment, hypomere are up big and down small cone segments; Offer feeding mouth on the interlude of cylindrical shell, an end of the said pipeline of winnowing links to each other with the sealing of the feeding mouth of cyclone separating tube, the other end links to each other with the air outlet sealing of said winnow.During work; Material to be cleaned (seed, clever chaff, short stem mixture) at a high speed is thrown into cyclone separating tube in through the pipeline of winnowing along the tangential direction of cyclone separating tube by winnow; Under the acting in conjunction of inertia force, gravity and air-flow, the bigger seed of proportion along the cyclonic separation barrel in the shape of a spiral track mouthful move to putting out cereal, the less light foreign material of proportion are to the cyclone separating tube central motion; And discharge by impurity adsorbing blower through the gettering pipeline, realize separating of light foreign material such as seed and clever chaff.The cleaning and sorting system of said structure, the axis of cylindrical shell open upper end overlaps with tubular axis, and the wind-force that impurity adsorbing blower produces mainly concentrates on the axial location of cylindrical shell; Get into the material to be cleaned in the cyclone separating tube, a part of seed near the axial location of cyclone separating tube, is siphoned away by impurity adsorbing blower with light foreign material in getting into cyclone separating tube the time; Cause cleaning loss; In order to reduce cleaning loss, strengthen the diameter of cyclone separating tube usually, this just requires to improve the ability of impurity adsorbing blower; Make the impurity adsorbing blower physical dimension increase or the rotating speed raising, increased cost again.
The utility model content
The purpose of the utility model provides a kind of under the prerequisite that does not strengthen the cyclone separating tube diameter, can reduce the cleaning and sorting system of the cleaning loss of cleaning and sorting system, and the cyclone separating tube that is applied in this cleaning and sorting system is provided simultaneously.
The cyclone separating tube of the utility model adopts following technical scheme: a kind of cyclone separating tube; Comprise cylindrical shell; The interlude of cylindrical shell is that column body segment, two sections are cone segments; The separating pipe that being used for of being communicated with on the said column body segment that radial direction extends is communicated with winnow, separating pipe protrude the column body segment barrel of cylindrical shell away from the sidewall of tubular axis.
The barrel of said cylindrical shell column body segment and separating pipe be arc surface away from the transition face between the sidewall of tubular axis.
The cleaning and sorting system of the utility model adopts following technical scheme: a kind of cleaning and sorting system; Comprise cyclone separating tube; Said cyclone separating tube comprises cylindrical shell, and the upper end of cylindrical shell is communicated with on impurity adsorbing blower, the interlude and is communicated with winnow, and the interlude of cylindrical shell is that column body segment, two sections are cone segments; The separating pipe that said column body segment extends through its radial direction is communicated with winnow, separating pipe protrude the column body segment barrel of cylindrical shell away from the sidewall of tubular axis.
The barrel of said cylindrical shell column body segment and separating pipe be arc surface away from the transition face between the sidewall of tubular axis.
Adopt the cleaning and sorting system of said structure and be applied in the cyclone separating tube of this cleaning and sorting system; Be communicated with the separating pipe that radially extends on the column body segment of cyclone separating tube; And the column body segment barrel away from the sidewall of tubular axis protrusion cylindrical shell of separating pipe; Guaranteed like this to wait to clean material in getting into cyclone separating tube the time as much as possible away from the axial location of cylindrical shell, reduced the amount that seed is siphoned away by impurity adsorbing blower, need not increase barrel diameter and can realize reducing cleaning loss yet.
In addition, separating pipe away from the barrel of the sidewall of tubular axis and cylindrical shell column body segment through the arc surface transition, help material better along orbiting motion in the shape of a spiral, improve the ability of cleaning of cleaning and sorting system.
