Abstract
A kind of feed bin material detection device, for flour processing field.Shell is fixed with elasticity static contact and movable contact spring, shell is threaded, and nut one and nut two are spun on shell, and shell one end cover has dust protection rubber cover, and dust protection rubber cover intermediate sleeve is in the end of movable contact spring, and movable contact spring is connected with baffle plate; With spring plate on movable contact spring; Shell one end is provided with for the movable square hole of movable contact spring within it; Static contact and spring plate are respectively equipped with stationary contact and moving contact.The utility model is for detecting in flour process in material silo with or without material, this device is arranged on bin bottom, when having wheat or flour, carry downwards due to wheat or flour or in flow process, downward pressure produced, because square hole size is larger than the movable contact spring size in it to baffle plate, movable contact spring can square hole be fulcrum, centre is upturned, and the moving contact on spring plate is contacted, switch conduction with the stationary contact on static contact.Easy for installation, reliability and durability, structure is simple, with low cost.
Description
Technical field
The utility model relates to flour processing technical field, specifically a kind of feed bin material detection device.
Background technology
In flour processing process, it is the important evidence judging whether system normally works that material in pipeline detects, be control system work whether, realize important parameter that is energy-efficient and early warning, therefore effectively accurately detect particularly important.Traditional feed bin material detection device, in order to cost-saving, considered technology maturity and complexity, generally be have employed reflected infrared sensors as signal acquisition terminal, realizes detecting by arranging a glass window at duct wall.But the material transfer canal due to flour processing place is different from the detection in other field, by the impact of pipeline internal memory at more dust, easily cause glass visibility to reduce in use for some time, and and then cause sensor to be judged by accident.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of feed bin material detection device, with solve traditional infrared sensor because of dust cause judge by accident problem.
For achieving the above object, shell of the present utility model is fixed with elasticity static contact and movable contact spring, shell is threaded, nut one and nut two are spun on shell, one end cover of shell has dust protection rubber cover, and the intermediate sleeve of dust protection rubber cover is in the end of movable contact spring, and movable contact spring is connected with baffle plate.
With spring plate on described movable contact spring.
One end of described shell is provided with for movable contact spring square hole movable within it.
Described static contact and spring plate are respectively equipped with stationary contact and moving contact.
Main application of the present utility model to detect in flour process in material silo with or without material, this device is arranged on the bottom of feed bin, when having wheat or flour, in the process of carrying due to wheat or flour or flow, downward pressure is produced to baffle plate downwards, because the size of square hole is larger than the size of the movable contact spring in it, movable contact spring can square hole be fulcrum, centre is upturned, and the moving contact on spring plate is contacted, switch conduction with the stationary contact on static contact.
The utility model compared with prior art, has the following advantages:
(1) easy for installation, only need to open circular hole on equipment, pick-up unit is put into it, then adopt and be screwed.
(2) by mechanical elasticity switch, and be added with dust protection rubber cover, reliability and durability, avoid traditional infrared sensor because of dust cause judge by accident deficiency.
(3) structure is simple, with low cost.

Fig. 1 is perspective view of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the switch sections sketch of Fig. 1.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, shell 3 is fixed with elasticity static contact 1 and movable contact spring 2, shell 3 is threaded, nut 1 and nut 25 are spun on shell 3, one end cover of shell 3 has dismountable dust protection rubber to overlap 6, and the intermediate sleeve of dust protection rubber cover 6 is in the end of movable contact spring 2, and movable contact spring 2 is connected by the mode of welding with baffle plate 7, when movable contact spring 2 is stressed, dust protection rubber cover 6 also can deform with it; With spring plate 8 on described movable contact spring 2, when movable contact spring 2 bends because baffle plate 7 is stressed, spring plate 2 contacts with static contact 1, thus movable contact spring 2 and static contact 1 conducting, switch conduction; One end of shell 3 is provided with for the movable square hole 9 of movable contact spring 2 within it, and the size of square hole 9 is slightly larger than the size of movable contact spring 2, and therefore, movable contact spring 2 can have certain space to rotate up and down in square hole 9; Static contact 1 and spring plate 8 are respectively equipped with stationary contact 11 and moving contact 10, to ensure that static contact 1 contacts well with spring plate 8, and durable in use.
This device is arranged on the bottom of feed bin, when having wheat or flour passes through, in the process of carrying downwards due to wheat or flour or flow, downward pressure can be produced to baffle plate 7, movable contact spring 2 can square hole 9 be fulcrum, centre is upturned, thus the moving contact 10 on spring plate 8 is contacted with the stationary contact 11 on static contact 1, switch conduction.
