Description
Technical Field
The utility model belongs to seed processing equipment mainly relates to a corn seed threshing, proportion select, size select, selection by winnowing, dust removal and edulcoration combined operation system.
Background
In recent years, corn seed processing enterprises in China introduce a low-breakage-rate corn seed threshing machine from abroad, and the threshing machine is matched with a sieve type size sorting device for threshing, cleaning and processing operations of corn seeds. However, in practical operation, the cleaning and separating effect of the matching structure scheme is poor, namely, impurities such as broken cores, bracts and filaments which are close to corn grains cannot be separated out, so that the impurity amount is large, the broken cores, bracts and filaments are too much to wind a fan to cause blockage of a winnowing pipeline, the equipment failure rate is improved, and meanwhile, the excessive impurities also cause overload operation of a winnowing and dust removing system, and the power consumption is increased. In view of the above problems, it is necessary to develop a cleaning system suitable for use with a low-breakage rate corn seed thresher introduced abroad so as to fully utilize and exert the technical advantages of the low-breakage rate corn seed thresher introduced abroad.
Disclosure of Invention
The utility model aims at solving the problems existing in the prior art, combining the actual need of the matched use of the low-breakage rate corn seed thresher introduced from abroad, developing and designing a corn seed threshing and cleaning system with a new structure, and achieving the purposes of reasonable matching, good cleaning quality, high processing efficiency, reliable use, few faults and strong applicability.
The utility model discloses a basic design is: the corn seed threshing and cleaning system is characterized in that a specific gravity sorting device is assembled at a position between a low-breakage-rate corn seed threshing machine and a three-layer screen type size sorting device which are mutually communicated, a feeding end and a discharging end of the specific gravity sorting device are mutually communicated with the low-breakage-rate corn seed threshing machine and the three-layer screen type size sorting device respectively, a dust hood is installed in the configuration where the specific gravity sorting device is mutually communicated, a pulse bag type dust collector is respectively communicated with the dust hood and a negative pressure suction fan through a dust suction pipeline and a negative pressure air pipeline, a positive pressure blower is installed on the bottom of the specific gravity sorting device, and an impurity outlet of the specific gravity sorting device is communicated with an impurity inlet of an impurity bin by an impurity removing pipeline conveying device, so that the corn seed threshing and cleaning system is formed.
The utility model discloses an add configuration proportion sorting unit between low breakage rate corn seed thresher and three-layer sieve formula size sorting unit to the edulcoration system that the cooperation is constituteed with suction hood, pulse bag collector, the dust collection system and the malleation hair-dryer of negative pressure suction fan combination, miscellaneous surplus storehouse has increased substantially and has cleaned the effect, the realization has with full play low breakage rate corn seed thresher's technical advantage, have the structure science, it is reasonable, thresh clean efficient, high quality, the operation trouble is few, the strong characteristics of adaptability.
Drawings
FIG. 1 is a schematic diagram of the general structure of a corn seed threshing and cleaning system.
Description of part numbers in the figures:
1. the device comprises a waste bin, 2, an impurity removal pipeline conveying device, 3, a low-breakage-rate corn seed threshing machine, 4, a specific gravity sorting device, 5, a dust hood, 6, a pulse bag type dust collector, 7, a negative pressure suction fan, 8, a three-layer screen type size sorting device, 9, a positive pressure blower, 10, a dust suction pipeline, 11 and a negative pressure air pipeline.
Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The utility model provides a corn seed cleaning system of threshing, includes low breakage rate corn seed thresher 3 and three-layer sieve formula size sorting unit 8, and position department assembles proportion sorting unit 4 between low breakage rate corn seed thresher 3 and the mutual intercommunication of three-layer sieve formula size sorting unit 8, proportion sorting unit 4's pan feeding end and discharge end communicate with low breakage rate corn seed thresher 3 and three-layer sieve formula size sorting unit 8 each other proportion sorting unit 4 top configuration installation suction hood 5 that communicates each other, pulse bag dust remover 6 through dust absorption pipeline 10 and negative pressure air pipeline 11 respectively with suction hood 5 and negative pressure suction fan 7 intercommunication install malleation hair-dryer 9 on proportion sorting unit 4 bottom, impurity removal pipeline conveyor 2 with proportion sorting unit 4's miscellaneous mouth and miscellaneous storehouse 1 miscellaneous mouth intercommunication.
During operation, the threshing mixed material obtained after the corn seed ears are threshed by the low-breakage-rate corn seed thresher 1 enters the specific gravity sorting device 4, under the blowing of the positive pressure blower 9, the threshing mixed material is in a suspension state on the inner table surface of the specific gravity sorting device 4, the heavy material in the threshing mixed material is positioned at the lower part, the light material is positioned at the upper part, heavy materials are conveyed to a three-layer screen type size sorting device 8 under the reciprocating action of an inclined table surface of a specific gravity sorting device 4, filaments, broken bracts and the like blown up by a positive pressure blower 9 in light materials pass through a dust suction hood 5 and a dust suction pipeline 10, and enters the pulse bag type dust collector 6 under the matching of the negative pressure air pipeline 11 and the negative pressure suction fan 7 for dust removal treatment and then slowly descends and is discharged, other broken cores, bracts and the like are conveyed into the impurity and residue bin 1 through the impurity removing pipeline conveying device 2 for centralized treatment, so that the cleaning and separating operation of the mixture after threshing by the low-breakage-rate corn seed threshing machine 1 is completed.
In the system, a threshing mixture after threshing by a low-breakage-rate corn seed thresher 3 is firstly subjected to a specific gravity sorting device 4, waste impurities such as filaments, broken bracts, broken cores and dust in light materials are basically removed, the load of a three-layer screen type size sorting device 8 on corn seed cleaning operation is greatly reduced, the seed cleaning quality and the operation efficiency are greatly improved, the system operation is smooth and free from blockage, the operation faults are few, technical support and guarantee are provided for an advanced corn seed threshing machine introduced from abroad to exert a good operation function, and the technical effect is obvious and outstanding.
