Abstract
The utility model relates to a granary top installation secondary clearing selection device which belongs to a wheat-rice combine harvester fitting device. The utility model is used to improve the clearing selection performance; and has a top sifter that is arranged on the top of a granary. One end of the top sifter is positioned on a sliding track, and the other end of the top sifter is connected with a crank. The discharge hole of the top sifter butts the inlet orifice of a helical feeder, and the inlet orifice of the helical feeder corresponds to the top of a first-level threshing cabinet. The inlet orifice of a hoisting machine is arranged on the top sifter and connected with the clearing selection chamber. The utility model meets the demands of complete threshing and dirt percentage, and threshing and clearing selection have good effect, the threshing rate can reach 99.5 percent under any weather condition, dirt percentage decreases to one percent. The utility model has simple and reasonable structure, convenient production and assembly. Also, the utility model can be both produced and modified with strong adaptability, thereby being favorable for promotion.
Description
Technical field
The utility model relates to a kind of silo overhead secondary cleaning plant, belongs to the wheat and rice combine harvester corollary apparatus, is used to improve sorting performance.
Background technology
In the wheat and rice combine harvester workflow, enter threshing cylinder behind the wheat rice crops process one-level threshing chamber, pass through cleaning room again, the long shoot bar is discharged from outside the machine, seed, disconnected fringe and broken short cane need be cleaned, outside grain husk chaff and the broken cane discharge machine, main seed, the disconnected fringe of part and short cane are promoted to silo by elevator, and disconnected fringe of part and short cane carry out final election by rethresher.Existing rethresher also only is to expect a fan blade impeller unit of Lower Hold one side after being fitted in threshing cylinder, be transported to again on the sieve plate behind the threshing cylinder by will break fringe and short cane of impeller wind-force, carry out programmed screening, can't veritably the fringe that breaks be carried out threshing again, and greatly disturbed the reasonable air-flow of cleaning room from the high wind speed of rethresher, reduced the function of cleaning of cleaning room, cause disconnected fringe of the overwhelming majority and the broken cane of part all to enter silo, influenced seed percentage of impurity and crop and taken off most rate index.If be subjected to the unfavourable weather condition influence in the process of crop growth, will in threshing course, produce a large amount of disconnected fringes and broken short cane, this problem is just more outstanding.
The utility model content
The purpose of this utility model is to provide a kind of silo overhead secondary cleaning plant, guarantees the most rate height that takes off of threshing, and percentage of impurity is low, and threshing and cleaning is effective.
Silo overhead secondary cleaning plant described in the utility model, the top sieve that places the silo top is arranged, one end of top sieve is fitted on the slideway, the other end of top sieve is connected on the crank, the discharging opening of top sieve docks with the charging aperture of auger conveyor, the discharging opening correspondence of auger conveyor is at the top of one-level threshing chamber, and the discharging opening that connects the elevator of cleaning room is positioned at sieve top, top.
Setting by top sieve and auger conveyor, after disconnected fringe of seed, part that promotes by elevator and short cane entered screen frame, seed fell into silo in the vibration processes of top sieve, and will not take off most fringe head, short cane is sent into the one-level threshing chamber, carry out real answering and take off, the fringe head that thoroughly will break takes off to the greatest extent.Guarantee the most rate height that takes off of threshing, percentage of impurity is low, and threshing and cleaning is effective.
After using the utility model, can directly former rethresher be removed, thereby keep the reasonable air-flow of cleaning room, give full play to the function of cleaning of cleaning room, reduce percent of loss and percentage of impurity.Also can keep original rethresher, be used for auxiliary adjustment, avoid the influence of the involutory stream of regulating the flow of vital energy of powerful wind-force again.
In the utility model:
Top sieve can be made of sieve plate and screen frame, and screen frame connects slide block, and slide block is fitted on the slideway, and screen frame is fitted in slideway by slide block, two body structures, install, use easy to adjust, as regulating slip angle etc.Slideway can directly be provided with on the silo, also can set up separately.
The connected mode of screen frame and slide block has a lot, and screen frame and slide block can be connected by adjustable plate is installed, and the installation adjustment hole is set installing on the adjustable plate, installs to regulate flexiblely, as the height of adjustment sieve plate etc., can satisfy instructions for use well.
During work, top sieve one end does reciprocating linear motion along slideway, and the other end is driven by crank and does the elliptical orbit motion.In actual production, can change linear movement direction by adjusting slip angle according to concrete crop situation, change the inclination angle of pushing up sieve by the setting height(from bottom) of adjusting top sieve one end, improve the adaptability of top sieve, satisfy instructions for use.
The utility model silo overhead secondary cleaning plant, most rate of taking off of threshing and percentage of impurity requirement have been satisfied, threshing and cleaning is effective, can both make to take off most rate and reach 99.5% under any weather conditions, and percentage of impurity reduces to 1%, and it is simple and reasonable, it is convenient to make, be equipped with, and both can produce, and can transform again, adaptability is strong, is beneficial to popularization.
Description of drawings
Fig. 1, the utility model one example structure schematic diagram.
Among the figure: 1, one-level threshing chamber 2, elevator 3, auger conveyor 4, slideway 5, screen frame 6, sieve plate 7, crank 8, crank drive shaft 9, silo 10, installation adjustable plate.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, silo overhead secondary cleaning plant described in the utility model, the top sieve that places silo 9 tops is arranged, the top sieve is made of screen frame 5 and sieve plate 6, one end of screen frame 5 is fitted on the slideway 4 by slide block or roller or roller bearing, screen frame 5 and slide block or roller or roller bearing are connected by adjustable plate 10 is installed, adjustable plate 10 is installed is provided with the installation adjustment hole, the other end of screen frame 5 is connected on the crank 7, the discharging opening of top sieve docks with the charging aperture of auger conveyor 3, the discharging opening correspondence of auger conveyor 3 is at the top of one-level threshing chamber 1, and the discharging opening that connects the elevator 2 of cleaning room is positioned at the top of top sieve plate 6.
Require installation to regulate according to routine, under the drive of crank 7, the top sieve does reciprocating linear motion, after promoting the disconnected fringe of seed, part that comes and short cane and enter screen frame 5 by elevator 2, in the vibration processes of top sieve, seed falls into silo 9, and auger conveyor 3 will not take off most fringe head, short cane is sent into one-level threshing chamber 1 once more, and the fringe head that will break thoroughly takes off to the greatest extent.
