<< First Embodiment >>
FIG. 1 is a cross-sectional view of a rough sorting machine according to the present embodiment. As shown in FIG. 1, the rough sorting machine 1 according to the present embodiment includes a hopper 10, a sorting net 11, a transport mechanism 2, a grain-raising conveyor 12, and a discharge duct 13.

The hopper 10 is arranged above the sorting net 11. The hopper 10 has an input port 101 for inputting grains (grains to be sorted) mixed with dust such as straw, and a supply trough inclined from the input port 101 toward the supply port 111 of the sorting net 11. It has 102 and. By charging the grains into the input port 101 of the hopper 10, the grains pass through the supply trough 102 and are conveyed from the supply port 111 to the inside of the main body 112 of the sorting net 11.

The sorting net 11 has a supply port 111 to which grains are supplied from the hopper 10, a main body 112, and a discharge port 113. The main body 112 is a tubular structure and has a mesh for sorting dust and grains. Further, the entire lower side of the main body 112 is the discharge port 113, and the grains that have passed through the mesh of the main body 112 are discharged from the discharge port 113 to the transport mechanism 2. In the present embodiment, the main body 112 is rotatably held by a motor (not shown), and when the main body 112 rotates, grains fall from the mesh of the main body 112 and pass through the discharge port 113. It falls to the transport gutter 3 of the transport mechanism 2. Most of the dust such as straw cannot pass through the mesh and remains inside the main body 112, so that the sorting net 11 sorts the grains and the dust.

The transport mechanism 2 is arranged below the sorting net 11, and transports the grains discharged from the discharge port 113 of the sorting net 11 to the grain lifting conveyor 12 by the screw conveyor 4 in a substantially horizontal direction. The details of the transport mechanism 2 will be described later.

The grain-raising conveyor 12 is a device for upwardly transporting grains transported by the transport mechanism 2. In the present embodiment, the grain-raising conveyor 12 has a grain-raising duct 121, a belt 122, a motor 123, and a plurality of buckets 124, and is attached to the belt 122 by driving the belt 122 with the motor 123. A plurality of buckets 124 can be moved along the belt 122. As a result, the grains transported to the lower part of the frying duct 121 by the transport mechanism 2 are scooped up by the bucket 124 and transported upward, and are discharged to the outside from the upper discharge duct 13. The grain-lifting conveyor 12 is not limited to the above configuration, and may be configured to transport grains upward by, for example, a screw conveyor.

In this way, the grains thrown in from the hopper 10 are sorted into dust and grains by the sorting net 11, and then fall into the transport gutter 3 of the transport mechanism 2. Then, the grains that have fallen into the transport gutter 3 are transported in a substantially horizontal direction by the transport mechanism 2, transported in a substantially vertical direction by the grain raising conveyor 12, and then discharged to the outside from the discharge duct 13. ..

Next, the transport mechanism 2 according to the present embodiment will be described. The transport mechanism 2 is a mechanism for transporting the grains that have fallen from the sorting net 11 to the transport gutter 3 to the grain lifting conveyor 12 by the screw conveyor 4. Here, FIGS. 2 to 4 are diagrams for explaining the transport mechanism 2 according to the present embodiment. Note that FIG. 2 shows a state in which the first adjusting plate 61 and the second adjusting plate 62 are not attached to the bottom 33 of the transport gutter 3, and FIG. 3 shows a state in which the first adjusting plate 61 is not attached to the bottom 33 of the transport gutter 3. Is shown, and FIG. 4 shows a state in which the second adjusting plate 62 is attached to the bottom 33 of the transport gutter 3. As shown in FIGS. 2 to 4, the transport mechanism 2 includes a transport gutter 3, a screw conveyor 4, magnet catches 51 and 52, and adjustment plates 6 (first adjustment plate 61 and second adjustment plate 62). ..

As shown in FIG. 3 or 4, the transport gutter 3 includes a left flow plate 31 on the left side surface of the transport gutter 3, a right flow plate 32 on the right side surface, and an adjusting plate 6 (first adjustment) of the transport gutter 3. It has a bottom surface composed of a plate 61 or a second adjusting plate 62). The left flow plate 31 and the right flow plate 32 are provided so as to face each other, and a screw conveyor 4 is interposed between them. Further, the left flow plate 31 and the right flow plate 32 are inclined, and the width between the left flow plate 31 and the right flow plate 32 becomes narrower toward the lower side. Further, the bottom 33 of the transport gutter 3 has a removable adjusting plate 6, and as shown in FIG. 2, the adjusting plate 6 is removed from the bottom 33 so that the transport gutter 3 does not have a bottom surface. It is possible to remove the grains remaining in the transport gutter 3 from the bottom 33. On the other hand, when the adjusting plate 6 is attached to the bottom 33 of the transport gutter 3, the adjusting plate 6 constitutes the bottom surface of the transport gutter 3 as shown in FIGS. 3 and 4.

In the present embodiment, the adjusting plate 6 has two types of first adjusting plate 61 and a second adjusting plate 62 having different shapes. As shown in FIGS. 2 to 4, the first adjusting plate 61 is fixed to the right flow plate 32 via the hinge 322. Similarly, the second adjusting plate 62 is fixed to the left flow plate 31 via the hinge 312. Further, the first adjusting plate 61 is rotatable about the hinge 322, and by rotating the first adjusting plate 61, the push latch 612 is locked at the lower end of the left flow plate 31. The first adjusting plate 61 can be attached to the bottom 33 of the transport gutter 3 by locking the 311. By pushing the push latch 612 while the first adjusting plate 61 is attached to the bottom 33 of the transport gutter 3, the locking between the first adjusting plate 61 and the locking portion 311 is released, and the first adjustment plate 61 is released. The adjusting plate 61 can also be removed from the bottom 33 of the transport gutter 3. Similarly, the second adjusting plate 62 is rotatable around the hinge 312, and by rotating the second adjusting plate 62, the push latch 622 is locked at the lower end of the right flow plate 32. The second adjusting plate 62 can be attached to the bottom portion 33 of the transport gutter 3 by locking the portion 321. Further, by pushing the push latch 622 while the second adjusting plate 62 is attached to the bottom 33 of the transport gutter 3, the locking between the second adjusting plate 62 and the locking portion 321 is released, and the second adjustment plate 62 is released. The adjusting plate 62 can be removed from the bottom 33 of the transport gutter 3.
As described above, in the transport mechanism 2 according to the present embodiment, the adjusting plate 6 attached to the bottom 33 of the transport gutter 3 can be easily switched between the first adjusting plate 61 and the second adjusting plate 62.

As described above, in the transport mechanism 2 according to the present embodiment, the adjusting plate 6 is attached to the transport gutter 3 by using the latch mechanism, so that the user attaches or removes the adjusting plate 6 to the bottom 33 of the transport gutter 3. The burden on the work can be reduced. That is, as a mechanism for attaching the adjusting plate 6 to the transport gutter 3, in addition to the latch mechanism, there are a toggle clamp mechanism, a lever clamp mechanism, a magnet mechanism, and the like. However, since the transport mechanism 2 according to the present embodiment is located at the lowermost part of the rough sorting machine 1, there is a problem that the operation space is narrow and it is difficult for the user to reach and apply force, so that the toggle clamp mechanism and the lever are difficult to apply. When a certain space is required for the operation or an operation for applying a certain amount of force is required as in the clamp mechanism, it is difficult for the user to attach / detach the adjusting plate 6 to / from the bottom 33 of the transport gutter 3. There was a problem. Further, in the present embodiment, since the transport mechanism 2 transports grains such as hard paddy, when the grains are transported using the magnet mechanism, the magnet increases when the pressure of the grains on the bottom surface of the transport trough 3 increases. There was also the problem that the mechanism would come off. On the other hand, the latch mechanism does not require a stronger force than other mechanisms, and even when the operation space is narrow and the user cannot reach it, the adjusting plate 6 is relatively easily transported. It can be attached to the gutter 3. Further, in the latch mechanism, by locking the push latches 612 and 622 to the locking portions 311, 321 even when the pressure of the grains on the bottom of the transport gutter 3 increases, the adjusting plate 6 can be moved to the bottom of the transport gutter 3. It can be firmly fixed to 33.

Further, FIG. 5 is a perspective view of the first adjusting plate 61 according to the first embodiment, and FIG. 6 is a perspective view of the second adjusting plate 62 according to the first embodiment. As shown in FIG. 5, the first adjusting plate 61 according to the first embodiment has a flat surface portion 611 forming the bottom surface of the transport gutter 3 when the first adjusting plate 61 is attached to the bottom portion 33 of the transport gutter 3. .. Further, as shown in FIG. 6, the second adjusting plate 62 according to the first embodiment has a convex surface portion 621 that constitutes the bottom surface of the transport gutter 3 when the second adjusting plate 62 is attached to the bottom portion 33 of the transport gutter 3.

The gap between the screw conveyor 4 and the flat surface portion 611 of the first adjusting plate 61 (that is, the bottom surface of the transport gutter 3) has a height H1. On the other hand, as shown in FIG. 4, when the second adjusting plate 62 is attached to the bottom 33 of the transport gutter 3 and the bottom surface of the transport gutter 3 is formed by the second adjusting plate 62, the second adjusting plate 62 has a convex surface. Since the portion 621 is provided, the gap between the screw conveyor 4 and the convex portion 621 of the second adjusting plate 62 (that is, the bottom surface of the transport gutter 3) is a height H2 (H2 <H1) lower than the height H1. Become.

By forming the bottom surface of the transport gutter 3 with the second adjusting plate 62 in this way, the gap between the screw conveyor 4 and the bottom surface of the transport gutter 3 can be narrowed. As a result, the remaining amount of grains in the gap between the screw conveyor 4 and the bottom surface of the transport gutter 3 can be reduced, and the waste loss of grains can be reduced. Further, when the bottom surface of the transport gutter 3 is formed by the second adjusting plate 62, the gap between the screw conveyor 4 and the bottom surface of the transport gutter 3 may be too narrow depending on the grain, and the screw conveyor 4 and the transport gutter 3 may be too narrow. Grains may get caught between the bottom and the bottom of the gutter and damage the grains. In such a case, by replacing the adjusting plate 6 constituting the bottom surface of the transport gutter 3 with the first adjusting plate 61 from the second adjusting plate 62, a gap between the screw conveyor 4 and the bottom surface of the transport gutter 3 is provided. As a result, it is possible to effectively prevent the grains from being caught between the screw conveyor 4 and the bottom surface of the transport gutter 3 and damaging the grains.

In the present embodiment, the first adjusting plate 61 and the second adjusting plate 62 are made of a magnetic material such as iron, and the outside (back side) of the left flow plate 31 and the right flow plate 32 according to the present embodiment. Are provided with magnet catches 51 and 52. As a result, as shown in FIG. 3, when the first adjusting plate 61 is attached to the bottom 33 of the transport gutter 3, the unused second adjusting plate 62 can be held by the magnet catch 51. Similarly, as shown in FIG. 4, when the second adjusting plate 62 is attached to the bottom 33 of the transport gutter 3, the unused first adjusting plate 61 is held by the magnetic force with the magnet catch 52. be able to.

As described above, the rough sorting machine 1 (conveyor mechanism 2) according to the present embodiment can be attached to the bottom 33 of the transport gutter 3, and by attaching to the bottom 33 of the transport gutter 3, the bottom surface of the transport gutter 3 is configured. It has two or more types of adjusting plates 6 having different shapes, and by replacing the adjusting plates 6, it is possible to change the height of the gap between the screw conveyor 4 and the bottom surface of the transport gutter. .. As a result, the height of the gap between the screw conveyor 4 and the bottom surface of the transport trough 3 can be adjusted according to the size of the grains to be transported such as rice and soybeans, and the grains remaining in the gap can be discarded. The loss can be reduced, and it is possible to effectively prevent the grains from being caught between the screw conveyor 4 and the bottom surface of the transport gutter 3 and damaging the grains.
