Specific embodiment
The preferred embodiment of seed screening plant of the invention is described further with reference to the accompanying drawing.
The preferred embodiment of seed screening plant of the present invention, as depicted in figs. 1 and 2, seed screening plant include that heating is dried
Equipment for drying and air separation units, heating, drying device include shell 1, and the top of shell 1 is provided with to be entered inside shell 1 for seed
Seed entrance, the bottom of shell 1 are provided with the seed export for the seed outflow inside shell 1.The bottom of shell 1 is also connected with
Accommodate the cabinet 13 of air separation units.
Seed entrance is connected with feed pipe 3, and the loading hopper 5 of taper is provided on feed pipe 3, is also set up on feed pipe 3
There is the inlet valve 4 of control seed influx.The discharge nozzle 33 for seed outflow is provided at seed export.
The heating, drying chamber dried to the seed in shell 1 is formd inside shell 1, in order to preferably add to entrance
Seed in hot drying cavity is dried, in heating, drying about three spaced apart stock guides 7 of intracavitary setting, stock guide 7
For straight panel, each stock guide 7 has the hinged end being hinged on the side wall of shell 1, and the blanking end opposite with hinged end, falls
Expect that there are the gaps to flow downward for seed between end and the side wall of shell 1.
In two neighboring stock guide 7, the hinged end of one of stock guide 7 is hinged in the opposite two side walls of shell 1
On one of side wall, the hinged end of another stock guide 7 is hinged on another side wall in the opposite two side walls of shell 1
On, each stock guide 7 tilts down arrangement by hinged end.Three stock guides 7, the guide in the top are selected in the present embodiment
Plate 7 is hinged on the side wall away from the closer side of seed entrance, so that seed is had on the stock guide 7 of the top sufficiently long
Flow path.
The blanking end of two neighboring stock guide 7 is between the hinged end of the two stock guides 7, makes two neighboring guide
Projection of the plate 7 in the same horizontal plane meets: the stock guide 7 that the blanking end projection of the stock guide 7 of top is below is fallen
Expect between end projection and hinged end projection, three stock guides 7 form interlaced arrangement form as shown in Figure 2, and seed is dried in heating
The reciprocal bending curve for doing intracavitary downward motion profile form of zigzag extends the seed movement intracavitary in heating, drying
Track, good drying effect.
By the interlaced arrangement of three stock guides 7, form seed in shell 1 when falling as shown in Figure 2
The reciprocal bending curve of "the" shape, in order to further increase drying effect, being additionally provided on each piece of stock guide 7 makes seed
The guide item 9 of the reciprocal bending curve of "the" shape is formed on each stock guide 7.
In the present embodiment, the stock guide in the top, the stock guide in centre divide on the stock guide in bottom
It is not provided with 4,6,6 guide items 9.Guide item 9 is provided on stock guide 7 it should be noted that illustrating only in Fig. 2,
Specific arrangement of the guide item 9 on stock guide 7 is not represented.
The hinged end for defining each piece of stock guide 7 is the front end of the stock guide, and the blanking end of stock guide 7 is the stock guide
Rear end.Specific arrangement of the guide item 9 on stock guide 7, as shown in figure 3, guide item 9 is in guide surface before and after stock guide 7
Direction interval setting at least two, each stock guide 7 is arranged perpendicular to guide surface, in two adjacent guide items 9, one of them by
From left end to right end, height is gradually risen before backward, and from right end to left end, height is gradually risen from the front to the back for another, so that kind
Son is guided after being exported by the guide item 9 in front side by the guide item 9 of rear side, and motion profile of the seed on stock guide is in reciprocal
The curve of bending forms the reciprocal bending curve of "the" shape on stock guide 7, further extends the movement rail of seed
Mark improves drying effect.
Each stock guide 7 is arranged that each 9 interlaced arrangement of guide item simultaneously tilts down cloth from hinged end to blanking end diagonally downward
It sets, makes seed that can flow downward under gravity.
Stock guide 7 in the present embodiment is heating board, and stock guide 7 is directly disposed as heating board, does not need additional set
Heating unit is set, while seed is also to move in the guide surface of stock guide 7, stock guide 7 can directly heat seed
Drying, drying efficiency are high.Stock guide 7 in the present embodiment uses the heating board of model CFXB40-50, using electrically heated side
Formula generates heat.
Stock guide 7 is also sequentially connected with vibration unit, and vibration unit can drive the vibration of stock guide 7 so that in guide surface
Seed flows downward, and is evenly distributed on seed in guide surface.In order to improve the concertedness of the vibration of stock guide 7, make each guide
The vibration frequency having the same of plate 7, preferably flows downward convenient for seed, and two neighboring stock guide 7 is passed through 10 phase of connecting rod
Even, when the vibration of one of stock guide 7, remaining stock guide 7 can vibrate therewith, and three stock guides 7 form an entirety, no
It needs individually to be equipped with vibration unit for each stock guide 7, reduces the cost of entire heating, drying device.
