Description

Powder and particle feeder

  The present invention relates to a granular material supply device for supplying agricultural powder (medicine, fertilizer, seeds, etc.) to a field.

As an example of the powder and granular material supply device, there is a fertilizer application device that supplies fertilizer to a field. Such a fertilizer application device includes a structure disclosed in Patent Document 1.
In Patent Document 1, a drive shaft (47 in FIG. 5 and FIG. 6 in Patent Document 1) is disposed laterally below a storage portion (43 in FIG. 5 of Patent Document 1) for storing fertilizer, and is disk-shaped. (Cylinder-shaped) feeding rolls (45 in FIG. 5 and FIG. 6 in Patent Document 1) (corresponding to a rotating body) are attached to the drive shaft, and a large number of recesses (see FIG. 5 and 45a) of FIG.

  Thereby, as the feeding roll is driven to rotate, when the concave portion of the feeding roll reaches the outlet portion of the storage portion (46b in FIG. 6 of Patent Document 1), fertilizer enters the concave portion of the feeding roll. Next, when the recess of the feed roll reaches the discharge position (position facing the supply pipe 44 in FIGS. 5 and 6 of Patent Document 1), fertilizer comes out of the recess of the feed roll and is supplied to the field.

  As described above, by rotating and driving a feed roll having a large number of recesses on the outer peripheral surface, it is possible to feed the fertilizer in the reservoir, and by changing the rotation speed of the feed roll, The feeding amount per unit time can be changed.

Japanese Patent Laying-Open No. 2011-142889 (see FIGS. 5 and 6)

In recent years, for example, in medicines, it has begun to be desired to continuously feed out powder particles (supplying powder particles to the field in a streak).
On the other hand, in Patent Document 1, when the recesses are arranged side by side on the outer peripheral surface of the feeding roll, it is necessary to form a partition between the recesses and the recesses, so that each time the recess of the feeding roll reaches the discharge position. It will be in the state where manure is drawn out, and will be in the state where a granular material is drawn out intermittently.

  In this case, if the feed roll is rotationally driven at a high speed, it becomes possible to continuously feed the powder particles. However, if the feed roll is rotationally driven at a high speed, the feed amount per unit time of the powder particles increases. Therefore, it is impossible to cope with a state in which the powder particles are continuously fed out while suppressing the feed amount per unit time of the powder particles.

  The present invention is configured in such a manner that the granular material can be continuously fed in the powder feeding device provided with the rotating body, particularly in a state in which the feeding amount per unit time of the granular material is suppressed. It is aimed.

Are arranged on the outer circumferential surface of the rotating body and arranged in the outer circumferential surface of the rotating body so as to cross obliquely with respect to the rotating direction. Accordingly, when the entering part reaches the outlet part of the storing part, the granular material enters the entering part from the storing part, and when the entering part reaches the discharge position, the particulates come out from the entering part. Are configured to be supplied to the farm.
In the above configuration, it is preferable that the seeding device and the fertilizer application are operated and stopped in conjunction with each other by operating the small number of clutches.
