[Detailed description of the invention]

[0001]

The present invention relates to a turning adjustment of a suction air blower for rice hulling, which can discharge dust including rice hulls in any desired direction only by a simple loosening operation of a tightening device. Related to the device.

2. Description of the Related Art Conventionally, a paddy supplied from a paddy tank 1 is removed by a pair of paddy rolls 2 and 3 and the obtained mixed rice and rice hulls are disposed in a separation casing 4 in a sorting air passage 5. And the rice is separated into brown rice, scrap rice and rice hulls by the suction sorting wind of the suction blower 6, the brown rice is collected as a product, the scrap rice is discharged outside the machine, and the rice hulls are passed through the suction duct 7. As shown in FIG. 5, a hulling sorter that sucks the air into the suction air blower 6 and discharges the rice to the rice husk storage through the air discharge duct 8 is known before the present application.

[0003]

By the way, in this kind of rice hulling sorter shown in FIG. 5, a suction air blower that discharges dust containing a large amount of rice hulls or the like does not turn in a direction in which the air discharge direction cannot be changed. It was fixed on the sorting housing. Therefore, in the case of performing a hulling sorting operation in a work place with a height limit using a suction exhaust fan only for upward exhaust, a suction exhaust fan only for horizontal exhaust that can be discharged in a horizontal direction. Use it as a replacement, or connect a curved pipe with a large exhaust resistance to the discharge side of the discharger of the suction exhauster dedicated to upward exhaust, to perform inefficient exhaust operation. There has been a problem that it is not possible to efficiently exhaust dust including rice hulls or the like in an arbitrary direction by the suction exhaust fan.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to make it possible to rotate a fan case of a suction blower by loosening a tensioning device. In addition to the above configuration, the fan case is fixed at an arbitrary position only by a simple tightening operation of the tightening device, and the exhaust direction of the suction exhaust fan can be freely changed and adjusted. The purpose of the present invention is to provide a turning adjustment device.

[0005]

In order to achieve the above-mentioned object, in the present invention, the turning adjustment device of the suction air blower for rice hulling is connected at the lower end to the upper end of the sorting air passage disposed in the sorting housing. A pair of left and right suction ducts, each provided with a mounting flange having an opening for dust suction on the inner side of the upper part, are installed on the sorting housing at intervals, and a pair of left and right mounting flanges are provided on the front side of the pair of left and right mounting flanges. A stepped fixed flange fitted to a stepped rotation support port opened on the left and right side walls of the fan case of the suction exhaust fan arranged between the suction ducts is opposed to each other, and suction is performed with a tensioning tool inserted through the mounting flange. The left and right side walls of the fan case of the exhaust fan are fixed by pinching.

[0006]

Now, a predetermined amount of paddy is supplied into the paddy tank, and at the same time, the paddy sorter and the suction exhauster are operated. Then, the selection airflow is generated in the selection air path from the intake window to the suction exhaust fan by the suction action of the suction exhaust fan. In this state, the paddy is supplied to the pair of hulling rolls from the paddy tank to remove the paddy, and at the same time, the detached grains are supplied to the sorting wind path. Then, while the degranulated particles are flowing down in the sorting air passage, they are separated by the sorting wind into three types of dust including brown rice, unremoved chaff and rice husk, and only the dust is sorted in the sorting passage. The air is further discharged through a suction duct through a suction air blower to be processed.

By the way, when the above-mentioned hulling sorting operation is to be performed by using a suction exhaust fan (see the solid line in FIG. 1) of a type dedicated to upward exhaust air installed in a work place having a restriction in the height direction. Cannot discharge dust in the upward direction. In such a case, first, loosen the tightening tool to release the clamping state of the mounting flange and the stepped fixing flange that clamp and fix the left and right side walls of the fan case of the suction and exhaust fan, and then perform suction and discharge. After rotating only the fan case of the blower in a direction in which the discharge direction is not obstructed, for example, in the horizontal discharge direction (see the chain line in FIG. 1), if the clamping direction is fixed again by the tightening operation of the tightening device, the exhaust direction is changed. It is easily turned, and dust such as rice husks can be efficiently discharged to the outside of the machine.

Therefore, in the device according to the present invention, even if only one suction blower is used, the dust discharge direction can be set to an appropriate direction according to the installation condition in the workplace only by a simple loosening operation of the fastener. In this way, it is possible to carry out efficient discharge work by adjusting the deflection.

[0009]

An embodiment will be described with reference to the drawings. In FIG. 1 to FIG. 4, reference numeral 101 designates dehulling and sorting of the supplied paddy to separate unpolished rice, unpulled paddy and dust including rice hulls, and collects the obtained brown rice as a product.ぷ Pulley is supplied to the mixed rice tank and de-sorted again, and dust containing rice hulls and the like is a hulling sorter that can be discharged to a rice hull storage etc. by a suction exhaust fan, and the hulling sorter 101 Is roughly divided into a huller 102 in which a pair of hulling rolls 103, 103 are rotatably mounted and a sorting wind that circulates mixed rice that has been crushed. A sorting housing 104 in which a sorting air passage 105 for sorting by dust is installed;
