Description
Technical field
The utility model relates to seed purifier, and what be specifically related to a kind of seed purifier closes bellows.
Background technology
Seed could be put in storage through screening usually.The screening of seed is divided into primary election and selected, what primary election adopted usually is first clear, is used for removing the bigger material in seed and light foreign material, selected employing be refiner, be that seed is carried out sorting by density and size further.
The primary structure of existing seed purifier comprise feed hopper, be communicated with feed hopper seed is sucked Classification Desk and the Pneumatic System of wind-force is provided, is used for the Classification Desk that seed is carried out sorting by density and size and the receiving hopper be communicated with Classification Desk for Classification Desk.The main weak point that above-mentioned seed purifier exists is: 1. during work, seed directly enters Classification Desk by conveying pipeline, and in order to pass through pneumatic seed-transportation, certain air-flow can be passed in conveying pipeline, this part air-flow enters Classification Desk easily via the mouth of pipe of conveying pipeline, and the negative pressure state in Classification Desk cannot be ensured, and affect separating effect.
Utility model content
What the utility model was intended to provide a kind of seed grading refiner closes bellows, to avoid the air-flow in conveying pipeline to enter Classification Desk, and affects the vacuum effect in Classification Desk.
Seed grading refiner in this programme close bellows, comprise casing, the top of casing is provided with the seed inlet be communicated with flexible conveying pipeline, the bottom of casing be provided be communicated with seal closure go out kind of a mouth, the first baffle plate is provided with in casing, the inwall of casing is provided with the bellows of a level, pressure door is provided with in the end of described bellows, the lower end of the first baffle plate is to pressure door lopsidedness, the lower end of described pressure door and the lower end of the first baffle plate form seed channel, and this passage is relative with going out kind of mouth.
This programme close the operation principle of bellows and beneficial effect as follows: kind of the mouth that goes out closing bellows is in closed condition in a non-operative state, only have when seed has certain accumulation at pressure door place, the gravity of seed pushes pressure door open, and seed enters the seal closure of Classification Desk from going out kind of a mouth.Closing bellows and both can having ensured that seed can enter Classification Desk smoothly of this programme, can prevent air from entering seal closure from going out kind of a mouth simultaneously, is in certain negative pressure state when ensureing Classification Desk's work.
Further, the inwall of described casing is also provided with the first guide plate of level, the bottom of the first guide plate is provided with the second guide plate, the lateral surface of the second guide plate is inclined-plane, the upper end of described pressure door has round and smooth hemisphere face, and described hemisphere face can contact with the bottom surface of the first guide plate and the inclined-plane of the second guide plate respectively.When pressure door rotary opening and closing, because hemisphere face contacts with the bottom surface of the first guide plate and the inclined-plane of the second guide plate respectively, therefore the rotary motion of pressure door is had to the effect of guiding.
Further, the sidewall of casing has via hole, be equipped with a cantilever in via hole, the aperture of via hole is greater than the diameter of cantilever, and one end and the pressure door of cantilever are hinged, the other end of cantilever and the upper end thereof of extension spring arranged below it.Pressure door by cantilever, extension spring, make kind of the mouth that goes out closing bellows be in closed condition in a non-operative state, and seed have necessarily pile up time, the gravity of seed forces pressure door overcome the power of extension spring and push pressure door open.
Further, also comprise second baffle, the upper end of described second baffle is fixed on the inwall of casing, and the other end of second baffle is fixed on the top of described first guide plate side, and described second baffle is from top to bottom to the centroclinal setting of casing.Second baffle is set, because second baffle tilts, the seed entered therefore can be avoided to be deposited in the top of the first guide plate and cannot to fall.
