Description
Technical field
The present invention relates to a kind of agriculture and animal husbandry equipment part, in particular to a kind of totally-enclosed discharging device of leak-proof.
Background technique
Slide valve be powdery, crystal grain material, little particulate material flow conveying control capital equipment, be widely used in metallurgy,
The industries such as mine, building materials, grain, chemical industry, country's Pneumatic gate valve is mainly by cylinder, valve body, flashboard, two-position five-way electromagnetism at present
Reversal valve composition.When being applied to the feed material leakage of farming and animal husbandry, the discharge port of the first closed feed bin of flashboard meeting, when its materials inside is deposited
Product to it is a certain amount of when open flashboard again, to carry out material leakage.
Notification number is that the Chinese patent of CN202203428U discloses a kind of program-controlled pneumatic gate valve, including shell and valve
Plate, shell is interior to be arranged feed inlet and outlet, the cylinder of the outside connecting band magnetic switch of the shell, the telescopic end direction disengaging of cylinder
Material mouth, the telescopic end of cylinder are connect with the valve plate, connection control cabinet and close switch on the shell, described in control cabinet connection
Cylinder, the signal output end close to switch connect control cabinet.
Shell, is installed on the lower end of other feed bins by above-mentioned this program-controlled pneumatic gate valve, utilizes the extension and contraction control of cylinder
The opening and closing of valve plate, to control the blanking situation of material in feed bin.But since valve plate often carries out pull movement, with
The seal degree of shell can be reduced because of long service in working condition, and when material is dropped down onto and stored in feed bin inherently at it
Inside generates the air-flow of flowing, this is easy for so that the material of grinds leaks and generates dust, especially entire pneumatic flashboard
When valve installation site is higher, the material to leak is directly trickled down to the person.And dust diffuses in workshop for a long time, when concentration reaches
Open fire is encountered when to a certain degree can then explode, and there are biggish security risks.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of totally-enclosed discharging device of leak-proof,
It leaks with the dust generated when reducing thin material or its blanking, to improve the effect of workshop condition safety.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of totally-enclosed discharging device of leak-proof, including outer housing, the bottom of the outer housing offer discharge port, the shell
