A kind of blanking system of band blower fan
The present invention relates to a kind of agricultural machinery equipment, specifically, be the blanking system of a kind of band blower fan.
The feed system of straw granulator is the most all linear feed, from the direct blanking of charging aperture, because raw material is a pile one
Heap blanking, the when of being easily caused pinch roller binder, pressure increases, and because blanking amount is big, has little time process and has clout and accumulate in
Pinch roller limit, causes production efficiency to decline, and current blanking system sealing is the best, easily brings loss and the dirt of energy
The invasion of dye thing, affects service life.
Summary of the invention
Invention solves the technical problem that: present invention solves the technical problem that and is that providing a kind of reduces pinch roller pressure and raising
The blanking system of the band blower fan of production efficiency.
Technical scheme: the present invention uses following technological means to be realized: the blanking system of a kind of band blower fan, including module
Changing cutting agency and blower fan, described modularity cutting agency top is provided with blower fan, is provided with pinch roller bottom modularity cutting agency.
As preferably, described blower fan one end connects blast pipe, and one end connects discharge pipe.
As preferably, described blast pipe and the end points of discharge pipe terminate on pinch roller.
As preferably, the blanking system of described band blower fan, the module group of modularity cutting agency is least one set.
As preferably, the blanking system of described band blower fan, each group of number of modules is three, i.e. by upper module (5), in
The setting that cooperates of module (6) and lower module (7) forms.Modular setting is conveniently overhauled and processing.Blower fan produces negative
During pressure, the unnecessary raw material in pinch roller limit is inhaled into from blast pipe, and releases from discharge pipe, and this process constantly circulates, and raw material is at blast
Under become smoke-like, thus eliminate the buildup of pinch roller.
As preferably, described blanking system is externally provided with seal closure.Good airproof performance is airtight.
As preferably, the distance of the end-point distances pinch roller of described blast pipe and discharge pipe is 20-30cm.This distance is inhaled
Wind effect is best.
As preferably, described blanking system top is additionally provided with explosive-proof electromagnetic valve.
Beneficial effect: blower fan is arranged on blanking system by the present invention, when blower fan produces negative pressure, the raw material that pinch roller limit is unnecessary
Being inhaled into from blast pipe, and release from discharge pipe, this process constantly circulates, and raw material becomes smoke-like under blast, thus eliminates
The buildup of pinch roller, improves production efficiency, and seal closure enables to equipment good seal performance, airtight.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram, and wherein 1 is blower fan, and 2 is pinch roller, and 3 is blast pipe, and 4 is discharge pipe, and 5 is upper mold
Block, 6 is middle module, and 7 is lower module, and 8 is seal closure.
Fig. 2 is the structural representation of upper module, and wherein 5 is upper module, and 9 is grain forming passage.Middle module, lower module
Structure similar with upper module.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in further detail:
As it is shown in figure 1, the blanking system of a kind of band blower fan, including modularity cutting agency and blower fan 1, modularity cutting agency top
Portion is provided with blower fan 1, is provided with pinch roller 2 bottom modularity cutting agency, and specifically, modularity cutting agency includes that least one set depends on
The upper module 5 of secondary setting, middle module 6 and lower module 7, three modules in a group operationally cooperate connection.Such as Fig. 2 institute
Showing, upper module 5, middle module 6 and the lower module 7 often organized circumferentially are provided with two row's bolts, and bolt is the most corresponding, adjacent
Forming grain forming passage 9 between two groups of bolts, the raw material charging aperture from module centre position drops to pinch roller, blower fan 1 one
End connects blast pipe 3, and one end connects discharge pipe 4.The end points of blast pipe 3 and discharge pipe 4 terminates on pinch roller 2, blanking
System peripheral has seal closure 8, strengthens sealing property, and blanking system top is additionally provided with explosive-proof electromagnetic valve, improves security performance.At this
In invention, the distance of the end-point distances pinch roller 2 of blast pipe 3 and discharge pipe 4 is 20-30cm, the life of the present invention under this distance condition
Product efficiency is optimal.
Blower fan is arranged on blanking system by the present invention, and when blower fan produces negative pressure, the unnecessary raw material in pinch roller limit is from blast pipe
Being inhaled into, and release from discharge pipe, this process constantly circulates, and raw material becomes vaporific under powerful blast, thus constantly eliminates pressure
The buildup on wheel limit, improves production efficiency, and seal closure enables to equipment good seal performance, airtight.
As the deformation of preceding solution, the group number of modularity cutting agency is two or more situation, also at this
Within the protection domain of patent of invention.
