JP3005668U - Flow rate control plate for paddy sorting machine - Google Patents

Abstract

(57) [Summary] [Purpose] Even if foreign matter larger than the paddy is mixed in the paddy supplied from the paddy tank toward the flow gap, the foreign matter is restored by the elastic restoring action of the flow regulating plate itself. The flow rate gap is automatically maintained at a predetermined gap except when passing through so that good hull sorting work can be performed. [Structure] The paddy fed from the paddy tank 2 is fed between a pair of paddy rolls 3 and 3 through a flow rate gap L ₂ formed between a feeding roll 6 that rotates and a flow rate regulating plate 11 to roll the paddy. In the above, the flow rate regulating plate 11 is composed of a spring steel plate capable of elastic recovery.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flow rate regulating plate in a hull sorting machine.

[0002]

[Prior art]

 Conventionally, a hull sorting machine that feeds hulls supplied from a hull tank between a pair of hulling rolls through a flow rate gap formed between a feeding roll that rotates the hulls and a flow rate regulating plate for hulling Prior to application, for example, they are described and disclosed in Japanese Patent Publication No. 54155/1990 or Japanese Patent Laid-Open No. 53502/1993.

[0003]

[Problems to be solved by the device]

 By the way, the flow control plate used in this type of hull sorting machine was made of a rigid steel plate that could not be elastically restored, so during the hulling operation, the flow was fed from the hull tank toward the flow gap. When foreign matter larger than the paddy (for example, pebbles, wood chips, etc.) is mixed in the roughened paddy, the flow regulating plate is forced to move from the solid line position in FIG. As it is pushed open and curved, the flow gap becomes large, and more than a certain amount of paddy is supplied between the pair of paddy rolls, resulting in good padding work. Perhaps it is not possible, but there was a problem that the flow gap could not be finely adjusted accurately after the foreign matter had passed.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to provide the paddy supplied from the paddy tank toward the flow gap rather than the paddy. Even when a large foreign matter is mixed in, the flow rate gap is automatically maintained at a predetermined gap except when the foreign matter is passing due to the elastic restoration operation of the flow rate control plate itself, and a constant amount is always maintained. An object of the present invention is to provide a flow rate control plate in a hull sorting machine that can efficiently supply accurate hull sorting work by supplying the hulls to a pair of hulling rolls.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the flow regulating plate in the paddy sorting machine of the present invention, a pair of flow gaps formed between the feeding roll rotating the paddy fed from the paddy tank and the flow regulating plate is used. In the one which is fed between the hulling rolls and hulled, the flow rate regulating plate is made of a spring steel plate capable of elastic recovery.

[0006]

[Action]

 At the start of the hulling and sorting work, a predetermined amount of hull is put into the hull tank, and after adjusting the flow gap between the feeding roll and the flow regulating plate, the feeding roll and a pair of hull rolls are respectively Rotate in the direction of the arrow.

By the way, the paddy supplied from the paddy tank toward the flow rate gap sequentially passes through the flow rate gap by the feeding operation of the feeding rolls, and is supplied to and removed from the pair of paddy rolls.

By the way, during the hulling / sorting operation as described above, if a foreign matter larger than the paddy (for example, pebbles, wood chips, etc.) happens to be mixed in the paddy, the flow rate regulating plate will Although the foreign matter forcedly passing through the gap pushes it open from the solid line position in Fig. 3 toward the dotted line position, the flow rate regulating plate is made of a spring steel plate that can elastically restore, so The flow regulation plate is restored to the position shown by the solid line in FIG. 3 by the elastic restoring action of the spring steel plate except when it is passing, and the flow gap returns to the flow gap size selected at the start.

Therefore, even if foreign matter is supplied to the flow rate gap along with the paddy during the hulling / sorting operation, when the foreign matter passes through the flow rate gap, the foreign matter is simply opened temporarily and the foreign matter passes through. After that, the elastic restoring operation of the flow rate regulating plate automatically returns to the initial flow rate interval, a predetermined amount of paddy is supplied to the pair of paddy rolls, and good paddying work can be continued. .

[0010]

【Example】

Examples will be described with reference to the drawings. In FIG. 1 to FIG. 3, reference numeral 1 denotes a pair of hull rolls 3 and 3 that rotate inwardly at different speeds and roll the dried hull, and the resulting brown rice and hulls are blasted. A rice hull sorting machine capable of sorting brown rice and rice husks in a sorting unit (not shown), wherein the hulling sorting machine 1 has a hull gap L ₁ and different speeds from each other. A pair of paddy rolls 3 and 3 that rotate inwardly are mounted on the paddy-chamber 2, a paddy tank 4 arranged above the paddy-chamber 2, and a given amount of paddy supplied from the paddy-tank 4 It is composed of a feeding portion 5 that continuously supplies the grain to the grain clearance L ₁ .

The feeding section 5 is rotatably provided with a large number of feeding projections 7 ... A restricting plate is attached to a mounting member 9 protruding from a part of the peripheral surface of the shaft 8 via a tensioning device 10 so as to be freely removable and elastically recoverable, for example, a flow restricting plate formed by a spring steel plate. 11 and 11.

Then, the flow rate regulating plate 11 is fed out by the rotation adjusting operation of the regulation plate shaft 8 in the left-right direction, and the flow rate gap L ₂ formed between the roll 6 and the flow rate regulating plate 11 is adjusted to an appropriate opening degree. It is configured so that a predetermined amount of paddy can be supplied to the paddy gap L ₁ by adjusting so that Reference numeral 12 is a supply adjusting plate provided in the lower part of the paddy tank 4, and 13 is a small stone, a piece of wood, and other foreign matter.

[0013]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

According to the present invention, even when foreign matter larger than the paddy is mixed in the paddy supplied from the paddy tank, when the foreign matter passes by the elastic restoring operation of the flow rate regulating plate. Other than the above, the flow rate gap is automatically maintained at a preset degree of opening, and a certain amount of paddy is continuously supplied between a pair of paddy rolls to enable smooth paddy sorting work efficiently. In fact, the flow control plate can be surely prevented from being deformed inadvertently, and the flow gap can be finely adjusted at any time.
