Description
Technical field
The utility model belongs to corn mechanical threshing technical field of tools, and can also be used for corn available for processing of farm products educates
In kind experimental study, specially a kind of machine for threshing maize by single ear.
Background technology
During corn breeding, breeder mixes to seed to be paid close attention to the most, because zasiokaurin amount is big, if mixed
Sow will result in again after miscellaneous and go here and there powder between plant, this will increase the seed selection workload of offspring, and then extend the seed selection time.And mix
Often caused by threshing this link, thus how to ensure seed will not mechanical admixture it is most important for corn breeding.
With continuous application of the machine for threshing maize by single ear in corn breeding, its artificial threshing before not only instead of,
Save labor, and improve efficiency.And good thresing machine need to possess and both can guarantee that seed was complete in threshing course, and can is protected
Card seed is not contaminated.The machine for threshing maize by single ear structure used at present in production is substantially similar, and chaff discharging port is open
, a length of 10cm, a width of 4cm, its position is between fan and threshing chamber.Thresing machine is in the process of running, clear at the beginning of it to be
System is to be suctioned out the debris such as clever chaff by suck-back air-flow caused by fan, if running into the lighter jade such as less than normal, not full, silty
Rice seed, can so be such that seed is suctioned out in dropping process by air-flow, if continuing threshing, suctioning out seed can reenter again too much
In threshing chamber, so as to cause to mix, machine is cleared up once if per the complete single fringe of threshing, can thus substantially reduce work effect
Rate, and frequent shutdown is cleared up, and can also be had an impact to service life of a machine, and due to its present position, clear up also very not
Easily.
The content of the invention
The purpose of this utility model is to overcome the seed at existing thresing machine chaff discharging port to flow back to cause seed in threshing chamber
The technological deficiency that grain mixes.The purpose of this utility model is achieved through the following technical solutions.
A kind of machine for threshing maize by single ear, from top to bottom it is disposed with charging aperture, threshing chamber, air-flow just clear device and discharging
Mouthful, gap adjustment plate and the threshing cylinder with motor connection are provided with the threshing chamber, just clear device includes chaff discharging port to air-flow
And fan, the outside of chaff discharging port set fan, set a separation net at the chaff discharging port, the aperture of the separation net mesh is
0.35~0.6mm。
As the improvement to separation net, the separation net is welded at chaff discharging port.
Further, the separation net is welded on the outside of chaff discharging port, close to the side of fan.
Further, the area of separation net is more than chaff discharging port, and separation net is rectangle, and long side is respectively welded at 5, and short side respectively welds
Connect at 3.
Further, the mesh of the separation net is uniformly distributed.
Further, the mesh of the separation net is circular hole, and mesh diameter is 0.38 ~ 0.42mm.
Further, the mesh of the separation net is square hole, and the size of square hole is 0.4 mm × 0.4mm.
Further, the isolation thickness of net is 0.1mm, and separation net is rectangle, a length of 11cm, a width of 5cm.
The beneficial effects of the utility model：
1）Can be sucked out the tiny debris such as clever chaff, and seed is blocked, and avoids the mechanical admixture in threshing course；
2）Without frequently shutting down cleaning again in threshing course, save the time, improved operating efficiency；
3）Simple in construction, cost is low；
4）Application also may extend to the thresing machine of other similar crops；
Invention is described in detail with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 the utility model structure diagrams.
Reference：1. charging aperture；2. motor；3. threshing cylinder；4. gap adjustment plate；5. chaff discharging port；6. fan；7. go out

Embodiment
As shown in figure 1, a kind of machine for threshing maize by single ear, at the beginning of being from top to bottom disposed with charging aperture 1, threshing chamber, air-flow
Clear device and discharging opening 7, are provided with gap adjustment plate 4 and the threshing cylinder 3 being connected with motor 2 in the threshing chamber, at the beginning of air-flow
Clear device includes chaff discharging port 5 and fan 6, and the outside of chaff discharging port 5 sets fan 6, a separation net 9 is set at the chaff discharging port 5,
The aperture of the mesh of separation net 9 is 0.35 ~ 0.6mm.
At work, threshing cylinder 3 and fan 6 all start quickly to rotate thresing machine, and single ear corn enters from charging aperture 1,
The continuous rubbing between threshing cylinder 3 and gap adjustment plate 4, seed and corncob separate and under gravity from discharging openings
7 outflows, and the debris such as clever chaff is then discharged under suck-back airflow function caused by fan from chaff discharging port 5.The utility model is to existing
Just clear device is improved the air-flow of machine for threshing maize by single ear, a separation net 9 is installed at chaff discharging port 5, its aperture can be designed
Into can make the discharge of the tiny debris such as clever chaff, and relatively large seed is isolated net and stopped, will not discharge, the selective screening
Device can make thresing machine, and no longer cleaning is shut down in midway in the process of running, improves operating efficiency, avoids and mix.The separation net
It should be noted that should not be too thick during design, mesh distribution is uniform, need to be welded on the outside of chaff discharging port, to contact tight
It is close.
In the present embodiment：Separation net is tightly fastened at chaff discharging port by being welded on；Separation net is welded on the outside of chaff discharging port,
Close to the side of fan.The area of separation net is slightly larger than chaff discharging port, and separation net is rectangle, and long side is respectively welded at 5, and short side respectively welds
Connect at 3.Isolation thickness of net is 0.1mm, a length of 11cm, a width of 5cm, and the separation net is wire netting.
The mesh of separation net can be circular hole, and mesh diameter is 0.38 ~ 0.42mm；The mesh of separation net can also be side
Hole, the size of square hole is 0.4 mm × 0.4mm.
