Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to a double-ear fresh-eating corn ear picking and impurity removing operation assembly which can be assembled on a fresh-eating corn combine harvester.
Background
In recent years, with the increase of the demand of fresh corn, the planting area of fresh corn is rapidly enlarged, and the mechanized harvesting operation of fresh corn is mentioned on the working schedule. At present, the mechanical harvesting operation of fresh corn mostly adopts a traditional corn harvesting machine to perform one-time ear picking operation, but due to the huge difference between the physical characteristics of the fresh corn and the physical characteristics of the dry-cooked corn, particularly, the fresh corn is a double-ear corn (the dry-cooked corn is a single-ear corn), when the fresh corn is harvested, the ear loss rate is high, the recovery rate is low, meanwhile, the ear is mixed with more impurities such as straws, stems, leaves, plant leaves and weeds, the cleanliness of the fresh corn ear is poor, and the proceeding of subsequent operation procedures is influenced. In order to solve the problems, a scheme of adopting a blowing type centrifugal wind turbine to remove impurities from fresh corn has been developed, but various technical problems of large occupied space, difficulty in configuration and installation, easiness in blockage in operation, poor impurity crushing and returning effect and the like exist.
Disclosure of Invention
Aiming at the problems in the prior art, the invention designs a double-ear fresh-eating corn secondary ear picking and stem leaf impurity removing device by combining the actual requirements of the current fresh-eating corn mechanized harvesting operation, so as to achieve the purposes of ensuring the cleanliness of the fresh-eating corn ear mechanized harvesting operation, improving the ear picking recovery rate of the fresh-eating corn and reducing the loss of the ears.
The invention aims to realize the purpose that the secondary ear picking and stem leaf impurity removing device for the double-ear fresh-eating corn comprises a harvesting rack, wherein a fan shell and a secondary ear picking roller assembly are respectively arranged on the harvesting rack, and the fan shell is positioned at the upper part of the secondary ear picking roller assembly; the device comprises a fan shell, a secondary snapping roll assembly, a tangential wind impurity leading-out cylinder, a fan impeller shaft assembly with a fan blade, a cutting and tearing crushing fixed cutter and a cutting and tearing blade, wherein the central part of the lower side of the fan shell is provided with the axial wind impurity absorbing cylinder, the lower port of the axial wind impurity absorbing cylinder faces the secondary snapping roll assembly, the tangential part of the circumference of the fan shell is provided with the cutting and tearing wind impurity leading-out cylinder, the fan impeller shaft assembly with the fan blade is rotatably arranged in the fan shell, the outer end part of the fan blade is provided with the groove-shaped cutting and tearing blade, the inner wall surface of the circumference of the fan shell is provided with the cutting and tearing crushing fixed cutter, and the cutting and tearing crushing fixed cutter and the groove-shaped cutting and tearing blade are in cross insertion overlapping fit or are separated from overlapping fit.
The invention adopts a negative pressure cavity formed in a fan shell by a rotary fan impeller shaft assembly to suck sundries mixed in fresh corn ears picked by a secondary snapping roll assembly into the fan shell from an axial flow air impurity suction barrel, and after the smashing is completed through the matching of a groove-shaped cutting edge on a fan blade and a cutting, tearing and smashing fixed knife, the sundries are discharged from a cutting air impurity guide barrel to be returned to the field under the combined action of positive pressure air flow blowing force and throwing force of the fan impeller shaft assembly.

Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A double-ear fresh corn secondary ear picking and stem leaf impurity removing device comprises a harvesting rack 1, wherein a fan shell 6 and a secondary ear picking roller assembly 2 are respectively arranged on the harvesting rack 1, and the fan shell 6 is positioned at the position above the secondary ear picking roller assembly 2; the secondary ear picking roller assembly is characterized in that an axial flow air impurity absorbing cylinder 3 is mounted at the central position of the lower side of a fan shell 6, the lower port of the axial flow air impurity absorbing cylinder 3 faces a secondary ear picking roller assembly 2, a tangential flow air impurity guiding cylinder 4 is mounted at the circumferential tangential position of the fan shell 6, a fan impeller shaft assembly 7 with a fan blade 8 is rotatably mounted in the fan shell 6, a groove-shaped cutting and tearing edge 9 is formed at the outer end of the fan blade 8, a cutting and tearing cutter 5 is mounted on the circumferential inner wall surface of the fan shell 6, and the cutting and tearing cutter 5 and the groove-shaped cutting and tearing edge 9 are in crossed insertion overlapping fit or are separated from overlapping fit.
When in operation and use, the secondary snapping roll assembly 2 firstly picks off the second ear of fresh corn which is still connected with the straw and has the incomplete stalk-cutting, at the same time, after the fan blade 8 rotating actively and at high speed in the fan housing 6 sucks air from the axial flow air-suction canister 3 into the cavity of the fan housing 6, and discharged from the tangential wind impurity guide cylinder 4, negative pressure is formed in the fan shell 6 in the process of high-speed air flow, the negative pressure makes sundries such as straws, stems and leaves mixed in fresh corn on the secondary snapping roll assembly 2 flow with air and enter the fan shell 6 through the axial flow air impurity absorbing cylinder 3, the sundries are cut and smashed under the matching of the groove-shaped cutting edge 9 on the rotating fan blade 8 and the cutting, tearing and smashing fixed knife 5, under the condition that the throwing of the fan blades 8 and the positive pressure air flow of the fan impeller shaft assembly 7 are blown, sundries are discharged from the tangential flow air sundry guide cylinder 4 and returned to the field.
