Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rough rice rough sorting machine used when receiving paddy harvested by a combine or the like.

[0002]

[Prior art]

 Conventionally, the roughing-separator sorting machine used for receiving paddy has been used for sieving by sorting the sorting plate.Therefore, the swinging motion of the sorting plate not only vibrates the machine, but also imparts a swinging motion. Means is required and the structure is complicated.

[0003]

[Problems to be solved by the device]

 Therefore, the first object of the present invention is to eliminate the above-mentioned conventional drawbacks, that is, to reduce the vibration noise and simplify the structure by improving the vibration of the airframe and the complicated structure. The second purpose is to realize a versatile one that can be used for both rough selection and fine selection while being a sorter for rough selection and used for fine selection.

[0004]

[Means for Solving the Problems]

 In order to achieve the object described in the above paragraph, the present invention provides a cylindrical selection cylinder having a large number of selection holes of appropriate size on the peripheral surface in a substantially hermetically-sealed body, in which the supply side is placed at a high position and the discharge side is placed at a high position. It is possible that the lower part of the sorting cylinder is rotatably laid in a slightly tilted state and a suction air passage is formed below the sorting cylinder, and the sorting cylinder is smaller than the sorting hole of the sorting cylinder. It is characterized in that it can be replaced with that of the sorting cylinder.

[0005]

[Action]

 With this configuration, when the machine is started, the sorting cylinder rotates in a fixed direction with the supply side at a high position and the discharge side at a low position, and the suction selection wind blows in the suction air passage below the selection cylinder. As a result, the received paddy gradually flows into the supply side of the sorting cylinder and undergoes the rough sorting action.

That is, while the paddy that has flowed into the supply side moves toward the discharge side due to the rotation of the sorting cylinder, the paddy and small dust particles leak from the sorting holes on the peripheral surface and fall into the suction air passage. The small dust is discharged to the outside of the machine by suction sorting wind, and the paddy is taken out, and the straw chips and grains with branch branches that do not leak from the sorting hole are taken out from the discharge side and roughly sorted.

[0007] Further, when the rough-separated paddy is flowed into the supply side of the replaced sorting cylinder by replacing it with that of a sorting cylinder having a smaller sorting hole, the good rice in the paddy leaks from the sorting hole. Without dropping, the unprepared grains are leaked and picked up separately and carefully selected.

[0008]

【Example】

 The following is a description of a roughing sorting machine according to the present invention with reference to an embodiment diagram. (1) is a substantially airtight machine with a lid (5), and (3) is an upper part of the machine (1). A cylindrical sorting cylinder that is rotatably mounted horizontally with the supply side at a high position and the discharge side at a low position, and a plurality of sorting cylinders (3) (3) are arranged in parallel and the peripheral surface thereof is provided. A large number of selection holes (2) of appropriate size are formed in this area by tensioning a net. The selection cylinders (3) and (3) are supported on the supply side and the discharge side by a pair of drive wheels (6) and (7) and rotate in a fixed direction by the rotation of the drive wheels (6) and (7). Of.

Below the sorting cylinders (3) and (3), there are slanted grain plates (8) and (8) that receive the leaked substances from the sorting holes (2). ) One side of the airframe (1) has an air inlet (9) on the underside of the airframe (8), and the other side has a suction fan (11) at the upper end of the wind tunnel (10) for the sorting cylinder. (3) A suction air passage (4) through which suction sorted air blows is formed in a direction traversing the (3), and a bottom plate of the suction air passage (4) forms a waffle (12) (12) connection In the section, a horizontal conveyor gutter (13) with a screw conveyor for laterally conveying the leaked substance from the discharge side to the supply side is installed.

Reference numeral (14) is a take-out gutter for receiving and taking out what has flowed to the discharge side without leaking from the selection holes (2) of the selection cylinders (3), (3) and flows out from the end thereof. 15) is a paddy tank in which the lower part is formed into a funnel shape and two supply ports (16) (16) are opened. Each supply port (16) (16) is the supply side of the sorting cylinder (3) (3). I am looking into it. Further, (17) is a reel roller for feeding out the water in the paddy tank (15), which is directly connected to the speed change motor (M) and rotates.

Further, (18) is made of a flexible material such as a rubber plate which is installed in parallel with the rotation axis of the selection cylinder (3) so as to be rotatable between the selection cylinders (3) and (3). A blade for preventing clogging, wherein the blade for preventing clogging (18) has the same length as that of the portion forming the sorting hole (2) from the supply side to the discharge side of the sorting cylinders (3) (3). Is configured to abut and slide on the outer peripheral surface of the sorting cylinders (3) and (3).

Therefore, the selection holes (2) shown in FIG. 3 allow the selection cylinders (3) and (3) having appropriate sizes to be supported by the drive wheels (6) (6) and (7) (7). (6) When the suction fan (11) is started while rotating in a certain direction by the rotation of (7), the paddy in the paddy tank (15) is fed by the rotation of the lead roller (17). What flows from each supply port (16) (16) to the supply side of the sorting cylinder (3) (3) flows toward the discharge side, and during this time, paddy and small dust leaks from the sorting hole (2). Then, the air is filtered by the suction selection wind that blows through the suction air passage (4), the small dust particles are discharged from the suction fan (11) to the outside of the machine through the wind tunnel (10), and the paddy is sent laterally (13). ). In addition, the straw chips / grains with branch branches that do not leak from the sorting hole (2) reach the discharge side and fall into the extraction trough (14) from the end of the discharge side, and the straw chips are removed from the paddy.・ Grains with branch shoots and small particles are removed by coarse removal.

Next, the lid (5) is opened, and the sorting cylinders (3) and (3) are sequentially pulled up and taken out, and the sorting holes (2) of the sorting barrel (3) shown in FIG. 4 are taken out. Drop the sorting cylinder (3a) with smaller sorting holes (2a) from above the fuselage (1) and place its supply and discharge sides on the drive wheels (6) (6), (7) and (7). Then, the selection cylinders (3a) (3a) are rotated and the suction fan (11) is rotated, and the paddy taken out from the laterally sent gutter (13) by the rough selection is put into the paddy tank (15). When thrown in and fed into the sorting cylinders (3a) (3a) from the supply ports (16) (16) by rotation of the reel roller (17), immature grains in the paddy leak through the sorting hole (2a). Then, it was taken out by the horizontal gutter (13), and the good rice came to the discharge side without leaking and was taken out from the takeout gutter (14). As a result, roughly-sorted paddy is finely sorted and sorted into good-grained rice and immature grain.

In the rough selection and the fine selection, the increase / decrease in the supply amount into the selection cylinders (3) (3a) is controlled by adjusting the rotation speed of the lead roller (17) by the variable speed motor (M). Let them do it. Further, the selection cylinders (3) and (3a) shown in this embodiment have a cylindrical shape and the selection holes (2) and (2a) are formed by stretching a net. ) (3a) has a polygonal shape, or a perforated iron plate is stretched around the peripheral surface to form the selection holes (2) and (2a). Good to do.

[0015]

[Effect of device]

 As described above, the rough selection machine for rough paddy according to the present invention has a cylindrical selection cylinder (3) in which a large number of selection holes (2) of appropriate size are formed on the peripheral surface in a substantially sealed machine body (1). With the supply side at a high position and the discharge side at a low position, and is rotatably laterally mounted in a slightly inclined state, and a suction air passage (4) is formed below the sorting cylinder (3). Therefore, unlike a conventional rough paddy sorting machine used when receiving paddy, a sorting cylinder that forms a sorting hole (2) on the peripheral surface is different from the one that swings a sorting plate to perform screening. Since the selection is performed by the rotation of 3), the vibration and noise of the machine body generated by the swinging motion of the sorting plate is eliminated, and the means for imparting the swinging motion is not required, and the structure is simple. It could be done. In addition, rough sorting is performed by making the sorting cylinder (3) replaceable with a sorting cylinder (3a) having a sorting hole (2a) smaller than the sorting hole (2) of the sorting cylinder (3). By further finely selecting the paddy, it can be sorted into good paddy and immature grains, which can be used for both rough selection and fine selection, thus realizing a versatile sorter.
