The present invention relates to a continuous constant speed particle feeding device, it is suitable for supplying with particle and can destroy be easy to ground grains most.
Supply with continuously in the system of particle a constant speed,, can cause not only that with a common belt or spiral the broken of particle looses, and be difficult to make the constant speed feed that particle might be on request if what supplied with is to be easy to be subjected to ground grains with pre-provisioning request.In addition, slide if particle takes place, they are subjected to broken loosing easily, perhaps produce speed course latitude error, and the result can not reach the particle feed of the accurate constant speed of per unit rotation.
Initial stage of the present invention has proposed a particle feeding device that is applicable to above-mentioned granule materials, it comprises the hopper of a bottom surface gradient greater than supply material angle of repose, a feed roller is located at a side of hopper mouth, roller has a circumference friction face and the material friction of supplying with, adjustment doors with half garden shape section, passage with feed roller tube formation material, also have a discharging trough to be configured in following (the Japanese Utility Model communique sho 53-6221) of feed roller, its good result is generally acknowledged.
Yet in the above-mentioned particle feeding device, although what supplied with is granular material, the feed roller has only a coarse appearance friction face.Therefore, though, cause the ratio between feed roller speed and the feed amount to be damaged as long as feed roller speed low-frictional force feed fully just when feed roller speed improves, the material slip will take place.In addition, the particle of being discharged by material channel with the rotation of feed roller when the feed roller reaches a certain anglec of rotation, will slide in appearance and falls at the feed roller.Therefore, the material of being supplied with will drop out discharging trough discontinuously.
In addition, have bigger relatively diameter and be easy to be subjected under the broken diffusing situation at the supply particle because the sliding phenomenon material channel outside, the material of supplying with just fragile diffusing.
The purpose of this invention is to provide a kind of particle feeding device, it can overcome the shortcoming of above-mentioned prior art, even and to being easy to ground grains, also can supply with granule materials continuously pro rata and can not destroy them with feed roller speed.
As mentioned above, utilize a kind of continuous constant speed feeding device of with groove roller of harmless supply friable particle, just might reduce and material pressure still can constant speed be supplied with particle when reducing at material.And these particles can be supplied with reliably, are not easy to broken material and can not damage.In addition, the speed of feed roller 1 and feed amount are proportional, and the particle by passage 6 will never slip down above the appearance of feed roller 1, therefore do not have the possibility that particle is interrupted feed.
According to the present invention, the particle feeding device of a continuous constant speed is provided, it has a roller of with groove and supplies with particle, be not easy to ground grains and can not damage these, it comprises the hopper 3 of the degree of dip of a bottom surface 3a greater than confession material angle of repose, a feed roller 1, be located at a side of hopper 3 mouths 5, with a adjustment doors 2 with half garden shape section, passage 6 with feed roller 1 formation material, feed roller 1 has by many axial groove 7 formed external peripheral surfaces, and the width 1 of groove 7 and degree of depth s are enough to hold the lowermost layer particle 11 from the granule materials 10 of material channel 6.
Therefore, slide, and the speed of feed roller and feed amount be proportional, therefore the feed reliably of particle to the last no matter the speed of feed roller 1 how, can not make the material of being supplied with produce.In addition, though that the vertical dimension of passage 6 is reduced to is minimum, even particle 11 also can be easy to also unlikely broken the loosing of broken diffusing particle by feed reliably.
When feed roller 1 forwarded certain angle of rotation to, granule materials 10 was just fallen in the discharging trough 4.At this moment, material 10 will never slide along the outside face of feed roller, gives the position of deciding angle of rotation but be brought to corresponding to feed roller 1 in groove 7.Therefore, material can fall and continuous feeding.
With reference to accompanying drawing, the most preferred embodiment explanation of the present invention in conjunction with following can more clearly understand above and other objects of the present invention and characteristics of the present invention, wherein:
