The vertical helical mixing device
Technical field
The utility model relates to a kind of material mixing device.
Background technology
Granular material when package metro-measuring since between granular material because extruding causes large, the poor fluidity of frictional force, usually can in weighing hopper, produce arching phenomenon, namely granular material falls when reducing to a certain degree from discharging opening, material can become arcuation.At this moment, discharging opening is blocked, and granular material can not fall from discharging opening again.
In order to address this problem, present conventional method is to force broken arch with agitating device or at weighing hopper installation oscillator in hopper.Because agitating device and oscillator are often in running order, can cause that metering is inaccurate, and can damage weight sensor.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of broken arch when discharging, the vertical helical mixing device that broken arch is effective.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of vertical helical mixing device, comprise support, be located on the support and the bottom is provided with the barrel of discharging opening and is located at agitator in the barrel, described agitator comprises and is rotatably connected on the shaft that on the support and vertically connects barrel and is located at many rows puddler on the shaft, the bottom of described shaft is provided with helical blade, and the bottom of described helical blade is positioned at the discharging opening place of barrel.
For so that the mixing effect of this device is better, a kind of preferred technical scheme is: the downward-sloping setting of above-mentioned puddler, and horizontal by 10 ° to 30 ° angle.
For so that the operation of this device is more stable, a kind of preferred technical scheme is: above-mentioned vertical helical mixing device also comprises the reducing motor of being located on the support, and the motor shaft of described reducing motor links to each other with shaft by shaft coupling.
For so that this device has function of measuring, a kind of preferred technical scheme is: above-mentioned vertical helical mixing device also comprises to be located on the support and the weight sensor that links to each other with barrel.
The beneficial effect that the utility model brings is: vertical helical mixing device of the present utility model is provided with the helical blade of vertical installation in the bottom of shaft, agitator is only worked when blowing, helical blade had both played the effect of emptying door, can when blowing, rotate again and break up the material of arch camber, broken arch is effective, and does not affect the accuracy of metering.Many rows puddler on the shaft of agitator can further strengthen the broken arch effect, granular material is glided smoothly fulfil assignment.
Description of drawings
Below in conjunction with accompanying drawing vertical helical mixing device of the present utility model is described further;
Fig. 1 is the structural representation of vertical helical mixing device of the present utility model.
The specific embodiment
See Fig. 1, the vertical helical mixing device of present embodiment comprises support 6, be located on the support 6 and the bottom is provided with the barrel 1 of discharging opening and is located at agitator in the barrel 1.Agitator comprises the shaft 2 and many rows puddler 5 of being located on the shaft 2 that is rotatably connected on the support 6 and vertically connects barrel 1.Puddler 5 downward-sloping settings are horizontal by 10 ° to 30 ° angle.The bottom of shaft 2 is provided with helical blade 4.The bottom of helical blade 4 is positioned at the discharging opening place of barrel 1.
This vertical helical mixing device also comprises the reducing motor 3 of being located on the support 6, and the motor shaft of described reducing motor 3 links to each other with shaft 2 by shaft coupling.
This vertical helical mixing device also comprises to be located on the support 6 and the weight sensor 7 that links to each other with barrel 1.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
