In recent years, food safety and security needs have increased, and the use of pesticides has also been reduced in cereals. In addition, many pests have emerged that may be related to the effects of global warming, leading to a phenomenon that reduces the appearance and internal quality of cereals. ing. In particular, grain damage caused by stink bugs of rice, i.e., black-spotted rice, is often observed in cereals, and the color sorter for removing defective rice due to the appearance, i.e. color, described in Patent Document 1 is also spreading.

  As in Patent Document 1, there is a demand for a unit that is integrally provided with a sorting device, a lifting device that feeds the grain to the sorting device, a hopper that serves as a charging port, and a grain tank for storing the grain. In particular, there is a growing demand to arrange a color appearance sorting device in the line of the grain drying control facility as shown in FIG.

  In the configuration in which the current appearance sorting device is incorporated in the grain drying adjustment line, as shown in FIG. 1, the grain that has been dried by the grain drying device 3 is accumulated in the straw temporary accumulation tank 6 by the conveying device 4 and the coarse sorting machine 7. Is passed to the rice huller 8 and separated into brown rice and rice husk. Then, the grain size sorting machine 9 sends a brown rice grain size exceeding the standard to the stone removing machine 10. The layout is such that the sorter 16 is disposed in the subsequent path, and the brown rice serving as a product is deposited in the brown rice storage tank 11 via the transfer device 5.

  In the selection of the sorter shown in FIG. 1, it is necessary to select the sorter 16 having a large amount of processing in order to prevent the brown rice discharged from the stone remover 10 from being delayed by the sorter 16. At present, the price of the sorter 16 that sorts by appearance is high, and it is difficult to purchase by an authorized farmer and a bearer individual, and there are many forms in which inexpensive sorters with relatively low processing capacity are arranged on the line. It is done. In the layout where the sorter 16 having a low processing capacity is arranged in this way, it is planned that the appearance sorting operation is operated unattended at night or early in the morning, and the processing amount is covered by long-time operation. A large grain tank 17 as shown in FIGS. 2 and 3 is arranged above the machine 16, and a sorting unit 15 is formed by connecting an elevating device 18 to the grain tank 17.

  Since the sorting machine 16 of the current sorting unit 15 is configured to include a fixed quantity supply device of grain, a dropping chute, a color judgment unit, and an ejector of a high-pressure air injection port in the vertical direction, the height of the device Needs about 1.8m or more. In order to supply many grains continuously to the sorter 16 configured in this manner for a long time, a large grain tank 17 as shown in FIGS. 2 and 3 is arranged above the sorter 16. As necessary, the grain tank 17 itself and the pillar members that support it are thicker, thicker and heavier, and longer upwards and longer in order to increase strength. Also in the lifting device 18, in order to supply the grain from above the grain tank 17 having a high overall length, it is necessary to lengthen the entire length, which requires the strength of the lifting device itself and further driving power. The sorting unit 15 including these is configured as the sorting unit 15 having a high overall length, that is, an unstable and high center of gravity, an inferior assembly property and transportability (parts), and a high manufacturing cost. In addition, it is difficult to move the sorting unit 15 itself, and the current situation is that it is fixed to the installation surface of the work place by an anchor in order to prevent shaking and fall-down during an earthquake.

Therefore, the present invention arranges a tank that can continuously supply the grain to the sorter from the upper side of the sorter adjacent to the side portion, lowers the overall length of the tank, and further lowers its discharge port from the inlet of the sorter. Even if it is a tank configuration that lowers the center of gravity of the tank itself and stabilizes it, we propose a configuration that can continuously supply grains from the tank to the supply port of the sorter, and the thickness and use of the members that make up the tank Provided is a unit configuration of a grain sorter that reduces the amount and strength thereof, has a large integrated capacity even at low manufacturing costs, and has good parts transportation and assembly.

In addition, the unit itself of a grain sorter that can move stably and freely as a unit itself is provided by reducing the center of gravity and improving the stability by lowering the floor of the tank itself and the lifting device that supplies the grain to the tank. To do.

In order to achieve the above object, a unit configuration of a grain sorter according to claim 1 of the present invention is an integral unit of a grain lifting and lowering device including a charging hopper, a sorter, and a grain tank for storing grain. In the sorting machine unit provided, the outlet of the lifting device has a feeding path connected to the loading slot of the sorting machine, and the grains overflowing from the feeding path are configured to be stored in the grain tank. The lower end of the grain tank is joined to the circulation hopper below the lifting device, the grain stored in the grain tank is put into the lifting device, and the feeding path connecting the outlet of the lifting device to the feeding port of the sorter Grain that is input to the input hopper from the outside is supplied from the discharge port of the lifting device to the input port of the sorter and processed by the sorter and processed by the sorter. Unsatisfactory grain overflows into the grain tank After the loading to the input hopper from the outside, the grain in the grain tank is supplied from the lifting device to the input path, slightly exceeding the throughput of the sorter, and slightly overflowing from the input path It is configured to form a circulation path that is again put into the grain tank .

In order to achieve the above object, the unit configuration of the grain sorter according to claim 2 of the present invention is the unit configuration of the grain sorter according to claim 1, wherein the lifting device including the input hopper is an input hopper. A circulation hopper for feeding the grain supplied from the grain tank into the lifting device at a symmetrical position, and the feeding hopper and the circulation hopper are linked to each other in the presence or absence of grain ingress and Both are provided with shutters for regulating the amount.

The unit configuration of the grain sorter according to claim 3 is the unit configuration of the grain sorter according to claim 2, wherein the shutter provided in the input hopper and the circulation hopper is closed when one is open. Thus, each opening / closing operation is configured to operate oppositely.

The unit configuration of the grain sorter according to claim 4 is the unit configuration of the grain sorter according to claim 2, wherein the shutters provided in the input hopper and the circulating hopper are opened and closed in a symmetrical manner in conjunction with each other. Even if the opening degree of one of the interlocking shutters is changed, the amount of grains supplied from the charging hopper and the circulation hopper into the lifting device is always constant. It is.

The unit configuration of the grain sorter according to claim 5 is the unit configuration of the grain sorter according to claim 1, 2, 3, 4 or 5, and includes a grain tank adjacent to the rear of the sorter. In addition, a lifting device is provided in front of the grain tank and on the side of the sorter.

  According to the present invention, even if the grain can be continuously supplied to the input port of the grain sorter, the grain tank outlet is arranged lower than the input port of the sorter. By lowering the tank and lowering the total length of the grain tank and transport device, the center of gravity can be lowered, so it can be easily placed as a single unit that can be moved, and the strength of the grain tank and lifting device Therefore, it is possible to supply a grain sorter unit that can be made thin and reduce the amount of use of the member, thereby reducing the manufacturing cost.

  Further, since the driving power can be reduced by lowering the lifting device, the cost of the driving source can be reduced and the power consumption can be saved.

In addition, the grain sorter unit proposed by the present invention can easily separate the tank part to which the lifting device is connected, that is, the tank transport block, from the sorter. In addition to being able to work in a place where it can be easily separated and repaired, the sorter can be easily changed to a model with a different throughput, so it is attempted to place a sorter unit with a different throughput and slightly different external dimensions In some cases, it is not necessary to design a new tank and lifting device, and a unit with excellent manufacturing costs can be provided.

The color selection unit 20 shown in FIGS . 4 and 5 is composed of a connected body of a sorter 21 having a moving means (caster) 23 at the lower end and a tank transport block 22 having a moving means (caster) 23 at the lower end. Even if it is the case where it connects with the moving means 23 with which it comprises, the color selection unit 20 can be moved easily.

  The sorter 21 has a loading port 24 at the upper end, and sorts grains that have been put into the sorting machine from the loading port 24 according to the appearance, and selects a good grain from a good product port 25 and a defective product from a defective product port 26. It is discharged to the outside and supplied to the subsequent process.

  The tank transport block 22 includes a tank 27 and a lifting device 28, and the lifting device 28 is supported and fixed to the tank 27. The lower side of the tank 27 is inclined in the direction in which the lifting device 28 is provided, and the lower end thereof is connected to a circulation hopper 29 of the lifting device 28.

  At the lower end of the elevating device 28, there is provided a circulation hopper 29 connected to the lower end of the tank 27 and a charging hopper 30 provided in the symmetrical direction so that grains from the outside are supplied into the color selection unit. It has become.

  The lifting device 28 is a bucket lifting machine having a plurality of buckets in a series of belts. The bucket belt is rotated by transmission of power from the drive motor 31, and the grains put into the feeding hopper 30 or the circulating hopper 29 are moved upward. And then discharged from the outlet 32 of the lifting device 28.

The circulation hopper 29 is provided with a shutter 33, and the closing hopper 30 is provided with a shutter 34. Each of the circulating hopper 29 can be fixed at an intermediate position so that the closing amount can be adjusted in addition to being fully closed and fully open. As shown in FIG. 9, the shutter 33 and the shutter 34 are connected to the opening / closing lever 36. When the shutter 33 is opened by the fulcrum 35, the shutter 34 is closed and a hopper to be put into the lifting device 28 can be selected. Since the opening / closing amounts of the respective shutters can be adjusted simultaneously, the amount of grain supplied from both hoppers is regulated, and even if the grains are simultaneously supplied from both hoppers into the elevating device 28, oversupply is reached. It is possible to adjust the amount of grain put into the elevating device 28 so as to prevent it.

The discharge port 32 of the elevating device 28 is provided with an input path 37 connected to the input port 24 of the sorter 21, and the grains discharged from the output port 32 are preferentially transferred from the input path 37 to the input port 24. It comes to be supplied. The charging path 37 is provided with an overflow path 38, which is connected to the upper surface or the side surface of the tank 27, and is formed in the charging path 37 by grains that are sequentially deposited from the charging port 24 of the sorter 21. The grains filled in and overflowed from the input path 37 are accumulated in the tank from the overflow path 38.

  The sorter 21 is disposed behind the tank 27, and the lifting device 28 is disposed on the side surface of the sorter 21 and in front of the tank 27.

When putting the grain to be sorted into the color sorting unit 20, the shutter 33 of the circulation hopper 29 is closed and the shutter 34 of the feeding hopper 30 is opened, and then the grain is put into the feeding hopper 30. In this case, as shown in FIG. 9 , when both the shutters 33 and 34 are interlocked and opened and closed by the open / close lever 36 around the fulcrum 35, the shutter 34 is fully opened. As a result, the shutter 33 is closed.

In a state where the sorter 21 and the lifting device 28 are in operation, the grains thrown in from the feeding hopper 30 are raised by raising the plurality of buckets in the lifting device 28 and are thrown into the feeding path 37 from the discharge port 32. . Then, as shown in FIG. 6, it is introduced into the introduction port 24 of the sorter 21 connected to the introduction path 37. Since the sorter 21 is in operation, the grains input from the input port 24 are sorted by appearance, and the good rice is discharged from the good product port 25 and the colored rice is discharged from the defective product port 26 for selection. However, if the amount of grain that is input from the input hopper 30 and cerealed by the lifting device 28 is greater than the amount that can be processed by the sorter 21, the amount of grain supplied to the input path 37 is processed by the sorter 21. However, the grains that gradually flow up to the overflow path 38 reach the overflow path 38, and grains that are supplied from the lifting device 28 but cannot be processed by the sorter 21 enter the overflow path 38. Start overflowing.

  Since the tip of the overflow path 38 is joined to the upper surface or the upper side surface of the tank 27, the overflowing grain from the charging path 37 is introduced into the tank 27. The lower side of the tank 27 is inclined in one direction including the elevating device 28 and the lower end thereof is connected to the circulation hopper 29 of the elevating device 28. Since the shutter 33 is closed, the sorter 21 gradually enters the tank. The overflowing grain that cannot be treated begins to accumulate (see FIG. 7).

  When the grain in the tank 27 is full, the shutter 34 is closed as shown in FIG. 8 while the sorter 21 and the lifting / lowering device 28 are in operation, and the grain sorter 20 enters the grain from the outside. Is stopped, and the shutter 33 is opened to start supplying the grain in the tank 27 to the lifting device 28. In this case, the opening degree of the shutter 33 is adjusted so that the grains discharged from the discharge port 32 of the elevating device 28 accumulate in the input path 37 and slightly overflow into the overflow path 38 more than the processing amount of the sorter 21. Then, while adjusting the amount of the grain supplied from the tank 27 to the lifting device 28, the path for supplying the grain in the tank 27 to the sorting machine 21, that is, the tank 27, the circulation hopper 29, the lifting device 28, and the discharge port. 32. A circulation path of the grain composed of the input path 37, the overflow path 38 and the overflow path 38 is formed, and the sorter 21 preferentially sorts the appearance in the middle of the path to sort all the grains in the tank 27. 21. Separated into good rice and colored rice.

  Further, even when the supply of the grain to the color selection unit 20 from the outside is finished, the shutter of the charging hopper 30 is closed as shown in FIG. The amount of supply from the tank 27 to the lifting / lowering device 28 is adjusted so that the particles slightly overflow into the overflow path 38, or the shutter 33 and the shutter 34 interlocked with the opening / closing lever 36 as shown in FIG. The opening / closing lever 36 is adjusted so that the flow rate from the shutter 33 slightly overflows the overflow path 38 as described above.

  FIG. 10 is a diagram in which the embodiment of the present invention is arranged in a grain drying adjustment line. Grains harvested in the field are transferred from the input device 1 to the grain drying device 3 via the coarse sorter 2 and the transport device 4. Supplied and dried over time (from the evening of the previous day to the early morning of the next day). After drying, the dried grains are accumulated in the temporary accumulation tank 6 and the interior of the grain drying device 3 is emptied to the next field. Ready to accept the harvest at the plant. Then, the grain in the temporary accumulation tank 6 is supplied again from the coarse sorter 7 to the hulling machine 8 and if it is a koji, it is separated into rice husk and brown rice. After being supplied to the sorting unit 20 and subjected to sorting by appearance, the colored rice is discharged out of the machine from the defective rice port 26 of the sorter 21, and the good rice is supplied from the good rice port 25 of the sorter 21 to the brown rice storage tank 11. Then, it is packed and moved to another storage location by the transport device 12. By using the embodiment of the present invention, a large amount of grains can be provided for providing the tank 27 in the color sorting unit 20 even if the sorter 21 having inferior processing capacity is provided in the line due to price problems or the like. Therefore, it is not necessary to adjust the flow rate (processing amount) of the subsequent process of each device in the line, and the flow of the grain can be maintained without stress, that is, the line that is not clogged. Can be provided. Further, according to the embodiment of the present invention, since the tank 27 is lowered and has a low center of gravity, the elevating device 28 can also be lowered, and thus the stable tank transport block 22 can be configured.
