Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on this practicality
Embodiment in novel, the every other reality that those of ordinary skill in the art are obtained under not making creative work premise
Execute example, broadly fall into the scope of this utility model protection.
Shown in Fig. 1-2, the Semen Fagopyri Esculenti proportioning mixing apparatus that this utility model provides, including valve seat 1, valve plate 2.Valve seat 1
It is a rectangular box-like structure, including side 11,12,13,14.The two ends of side 11 connect side 12,13.Side 14 is by side
12, the other end of 13 couples together.Through hole 110 is offered in the centre position of side 11.The inwall of side 12,13 offers cunning respectively
Groove 120,130.Chute 120,130 is connected with through hole 110.Fixed range sensor 140 on the inwall of side 14.Valve plate 2
One end passes through hole 110, is slidably connected with chute 120,130, and the other end is connected on the sidewall of rotating shaft 3.When rotating shaft 3 rotates
Time, valve plate 2 can be wound in rotating shaft 3.By the rotation of rotating shaft 3, change valve plate 2 and enter the length in valve seat 1, and then change valve
The size that door is opened, it is achieved automatically control.Now, range sensor is able to detect that the end of valve plate 2 and the distance of side, from
And the size of valve opening can be calculated exactly, thus improve the precision of proportioning.
Such as Fig. 3, arranging casing 4 in the outside of valve seat 1, rotating shaft 3 is positioned at the outside of casing 4.Casing 4 offers air port
41, air port 41 is positioned at the top of side 11.Air port 41 is connected to recovery bin 42 by pipeline, arranges blower fan 43 on pipeline.Buckwheat
Wheat enters from the valve formed between valve seat 1 and valve plate 2, and part Semen Fagopyri Esculenti can drop on valve plate 2.If now changing other kinds
Wheat seeds, can the Semen Fagopyri Esculenti that remain on valve plate 2 be poured in valve, cause proportioning that trace error occurs.By starting blower fan 43
Produce negative pressure, make the Semen Fagopyri Esculenti remained on valve plate 2 adsorb, improve the precision of proportioning further.In order to realize automatization's control
System, improves efficiency, it is to avoid is switched on blower fan when changing wheat seeds every time, in one embodiment, also includes infrared sensor
6, infrared sensor 6 is arranged in casing 4, and the lower section in air port 41.Whether infrared sensor 6 is able to detect that on valve plate 2 to go out
The wheat seeds now remained, for as the criterion whether opening blower fan 43.
Sub-material body 5 is welded above casing 4.Sub-material body 5 is fixed on the top of valve seat 1, for guiding material to valve
Seat 1.Such as Fig. 4, rotating shaft 3 is connected to decelerator 8 by shaft coupling 7, and decelerator 8 connects motor 9.Motor 9, infrared sensor 6, wind
Machine 43 and range sensor 140 are connected to controller.Controller, according to the ratio of proportioning, controls the operation of motor 9, and then
Control the size of valve opening;Detect valve size by range sensor 140, when reaching the position meeting ratio, control
Motor 9 is out of service.Controller receives the information that infrared sensor 6 detects simultaneously, and controls blower fan 43 according to this information
Open and close.
In order to realize monitoring the storage condition of different wheat seeds, in one embodiment, also include container tank 10, container tank
The quantity of 10 determines according to the wheat seeds quantity of proportioning.Different wheat seeds are placed in different container tank 10.Each container tank 10
It is connected to sub-material body 5 respectively by pipeline 11.Electromagnetic valve 12 is set on pipeline 11.In the bottom of container tank 10, gravity sensitive is set
Device 13, gravity sensor 13 connects controller.Gravity sensor 13 wheat seeds in detecting tank are set in the bottom of container tank 10
Amount of storage, and the numerical value that detects is sent to controller.When its low memory is in setting value, controller sends alarm,
Corresponding wheat seeds are poured into remind.
