Plasticine block, therefore, it is possible to make described screw piece relatively easily be directed at described plasticine block, improves para-position stability.When
When described screw piece compresses described plugging hole and connects described insufflation channel, described screw piece pushes against described viscosity block and deforms and support
It is depressed on described pushing and pressing part, thus rotating described baffle plate using described pushing and pressing bar, to open described baffle plate.Now, described casing
Interior dust can pass through described clathrum under the promotion of compressed nitrogen and enter in described outlet tube.For example, for the ease of
Install described pushing and pressing bar, the side wall of described casing is concavely provided with sliding tray, and described catch bar is slidingly arranged at described sliding tray
In, described pushing and pressing part is cylindrical shape, its side wall offers multiple breach, described rubber sleeve is arranged in described pushing and pressing part.By
Offer sliding tray on the side wall of described casing, therefore, it is possible to certain guiding function is produced to described catch bar, prevent institute
State freely swinging of pushing and pressing bar.
For example, for the ease of when described powders grading equipment works, described baffle plate can be automatically switched off, on described baffle plate
It is additionally provided with extension spring 68, one end of described extension spring connects the edge of described baffle plate, the other end connects on described plugging block.For example,
The also insertion of the bottom of described casing offers inclined hole 69, and the relatively described installing groove of described inclined hole is obliquely installed.The side of described inclined hole
Side is connected by slit with described installing groove, and described extension spring is arranged in described inclined hole and is connected on described plugging block.For example,
The coefficient of elasticity of described extension spring is less than the coefficient of elasticity of described compression spring, and that is, the pushing force of described compression spring is more than described drawing
The pulling force of spring.When described powders grading equipment works, described plugging block, in the presence of described compression spring, can be jammed in
Described blow afloat in passage.When described screw piece pushes against described plugging block, under the cooperation of described extension spring, described plugging block can
Income is dissolved in described installing groove, and meanwhile, described screw piece also drives described baffle plate to open using described pushing and pressing bar.In order to keep
Sealing, the section of described inclined hole is circle, and the middle part of described extension spring is provided with slip blocking post 681, and described slide post stick harness is solid
In described extension spring and be slidingly arranged in described inclined hole, the described side sliding blocking post is formed with blocking sidepiece, institute
State blocking sidepiece to be slidingly arranged in described slit, so that described installing groove forms a rectangle completing, to keep
The sealing effectiveness of inclined hole.For example, the described blocking post that slides includes barrel-type casing and is contained in the radiating in described barrel-type casing
Matrix, described blocking sidepiece is convexly equipped on the side wall of described barrel-type casing, and described heat dissipation base can play certain radiating and make
With.The outside of described barrel-type casing is provided with sliding layer, and described sliding layer is arranged with the medial wall slip of described inclined hole.For example,
Form 18 degree of angle between the bearing of trend of the axis of described inclined hole and described installing groove.Described in described actuator drives
When compressing cam and compressing described feed hopper, described screw piece can synchronously push against described plugging block to open described gas hole, and
Described extension spring can discharge described baffle plate again, so that described baffle plate is opened under the pushing and pressing of described screw piece.So pass through actuator
Rotation driving can synchronously realize three actions, and then realize the automatization of described casing and clean, and described compressed nitrogen
It is prevented from the dust explosion in described casing again.
The technical characteristic that other embodiments of the invention are also included in the various embodiments described above be mutually combined formed can
The technical scheme implemented.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the guarantor of the present invention
Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
