Abstract

The utility model provides a cyclone lifter by utilizing rotating airflow to pick up cotton, which has no block in whole path. Therefore, the utility model can avoid the necessary for cleaning the enwound and jammed cotton, in order to pick up cotton with high achievement. The cyclone lifter comprises an air suction opening, diversion vanes and an air duct, which comprises a horn-like thin-wall tubular body. The air suction opening is a double-curved surface thin-wall pipe. The diversion vanes are in the form of airfoil edge and are arranged on the inner wall of the double-curved surface pipe axially. A helix angle (a) is positioned between the axes and the double-curved surface pipe. The air duct is a rounded thin-wall pipe. During the working, airflow enters the air duct along the air suction opening, and rotates under the function of the diversion vanes. When the air suction opening is near the cotton, the cotton are wrested from the plants and then enter the cotton storage swiftly through air duct and the flexible pipe of the vacuum cotton plucker connected with air duct, under the effect of rotating airflow.

Description

The one whirlwind extractor that grows cotton

Technical field

The utility model relates to the Mining that grows cotton and plucks device, specifically is meant to be used for one of the suction type cotton Mining off-hook whirlwind extractor that grows cotton.

Background technology

Suction type cotton Mining off-hook is the principle of negative pressure that utilizes similar dust catcher, plucks cotton rotating mechanism by drawing the Mining piching cotton, being equipped with in the existing absorption heads, needs often to remove and twines and stifled flower, so it is low to pluck cotton efficient, is awkward.

Summary of the invention

The utility model aims to provide a kind of cotton whirlwind extractor that utilizes swirling eddy to win cotton, twines and stifled flower phenomenon to solve.

The purpose of this utility model is achieved in that the whirlwind extractor that grows cotton, and comprises the thin-walled tubular body of the likeness in form loudspeaker that inlet scoop, water conservancy diversion fin, air channel one constitute, and wherein: described inlet scoop is the hyperboloid sheet-metal duct; Described water conservancy diversion fin shape wing edge like flying is distributed on the hyperboloid inside pipe wall vertically, its axis and hyperboloid pipe axis wire clamp α helical angle; Described air channel is circular sheet-metal duct; At work, air-flow enters the air channel along the inlet scoop, rotates under the effect of water conservancy diversion fin, when inlet scoop during near cotton, under the effect of swirling eddy, cotton is screwed from the plant and the flexible pipe of the suction type cotton Mining off-hook that joins by the air channel with the air channel rapidly enters the cotton storehouse of storage.

After the utility model adopts said structure,, reached to remove and twined and stifled flower, efficiently plucked cotton purpose owing to no any obstacle in whole passage.

Embodiment

As shown in Figure 1, the of the present utility model one whirlwind extractor that grows cotton comprises the thin-walled tubular body of the likeness in form loudspeaker that inlet scoop 1, water conservancy diversion fin 2, air channel 3 one constitute, and wherein: described inlet scoop 1 is the hyperboloid sheet-metal duct; Described water conservancy diversion fin 2 shapes wing edge like flying is distributed on the hyperboloid inner-walls of duct vertically, its axis and hyperboloid pipe axis wire clamp α helical angle; Described air channel 3 is circular sheet-metal duct; At work, air-flow 1 enters the air channel along the inlet scoop, under the effect of water conservancy diversion fin 2, rotate, when inlet scoop 1 during near cotton, under the effect of swirling eddy, cotton is screwed from the plant and the flexible pipe of the suction type cotton Mining off-hook that joins by air channel 3 with the air channel rapidly enters the cotton storehouse of storage; Because no any obstacle in whole passage has reached to remove and has twined and stifled flower, efficiently plucks cotton purpose.

Claims
