Description

  The present invention relates to a silo structure capable of selecting and storing either grains such as rice and wheat, or beans such as red beans and soybeans. The present invention relates to a silo structure capable of preventing cracks, cracks or damage.

  Conventionally, there are those described in Patent Documents 1 to 3 regarding the structure of a silo.

  In Patent Document 1, the lower surface of the silo is inclined with respect to the vertical line in order to prevent the grains from forming an arch structure in the vicinity of the silo outlet and closing the outlet. It is a structure provided with continuous or intermittent spiral fins. As a result, the lower surface of the spiral fin receives a granular pressure different from the arch stress, and the granular pressure in this portion is behind the fin and becomes smaller than the other portions. Even when the arches are being formed, collapse occurs under the fins, and the subsequent collapses occur one after another, preventing the formation of arches. .

  In order to prevent tearing of the outer shell due to impact force when dropping from a high place when feeding beans such as soybeans, the one disclosed in Patent Document 2 is spirally formed in the vertical direction along the peripheral wall surface of the silo. A flow-down supply basket is provided, and the upper end of the flow-down supply basket is connected to the grain supply port of the silo. As a result, the bean grains supplied to the upper end portion of the flow-down supply basket flow through the spiral supply basket at a low speed, overflow from the lower end, and the bean grains accumulate evenly. There is an action and effect that the grain supply efficiency can be improved by causing the grain to flow safely and smoothly into the silo without causing a grain surface tear.

  In Patent Document 3, a porous upright wind pipe is arranged inside an upright tube (equivalent to a silo) to adjust the storage temperature and humidity unevenness of the grain and prevent deterioration of the quality of the grain. And it is the structure which provided the air blower which goes to the lower end opening part of the same wind pipe, and arrange | positioned the spiral stepped grain porous chute in the outer peripheral space of a porous wind pipe. As a result, when the grain is introduced into the upright cylinder, the grain perforated chute descends spirally along the perforated upright wind pipe to the inclined bottom plate and is discharged sideways from the same wind pipe. In response to the wind, the wind passes through the perforated chute, passes through the ventilating plate of the upright cylinder, is discharged to the outside air, and has the effects and effects of being ventilated and dried by the wind.

  In the silo structures disclosed in the above-mentioned Patent Documents 1 to 3, all of the silos are provided with a spiral fin, a spiral flow-down feeding rod, or a spiral stepped grain perforated chute vertically downward inside the silo. Is. As a result, when storing round beans with a relatively large particle size such as red beans and soybeans, even if the angle of repose (eg 30 °) is designed to be loose, Since it rolls on the supply basket and the grain perforated chute at a low speed, the possibility of remaining on the fins, the falling supply basket and the chute is reduced. However, when storing grains with a relatively small particle size, such as rice or wheat, and a shape close to an ellipse, if you do not design based on the idea of making the angle of repose (for example, 45 °) steep, There is a problem that the flow of the grains is difficult, and the grains are not completely discharged from the silo and remain due to the accumulation of the grains on the fins, the flow feed rods and the chutes. As described above, there has been a problem in the past in designing a structure of a combined silo that selects and stores beans such as soybeans or grains such as rice and wheat.

  In addition, as shown in FIG. 11 of Patent Document 1, in the embodiment in which fins are attached to the outer periphery of the shaft passing through the center of the silo body so as to be wound around the shaft, There was a risk of damage to the shaft and fin.

  The structure of the silo 1 of the present invention mitigates the drop impact inside the cylindrical storage tank 2 for storing the storage object, the inverted frustoconical hopper 3 provided at the lower part of the cylindrical storage tank 2, and the rectangular machine casing 17. And a rectangular parallelepiped storage tank 6 having an inclined bottom surface ridge 5 having the same angle as the cone angle α of the hopper portion 3 so as to form a passage T that communicates with the hopper portion 3 through the communication port 14. . The inclined bottom surface 5 may be an inclined surface having an angle larger than the cone angle α. However, if the inclined surface has a gentle angle smaller than the cone angle α, the grains may be clogged or the residue may be generated, which is not appropriate. At the upper end of the cylindrical storage tank 2, a round canopy 8 having a grain inlet 7 for feeding only grains having a relatively small particle size such as rice or wheat and a shape close to an ellipse is provided. On the other hand, a rectangular canopy provided with a bean inlet 9 for feeding only rounded beans having a particle size larger than grains such as red beans and soybeans at the upper end of the rectangular parallelepiped storage tank 6 10 is applied. Furthermore, the lower end of the hopper 3 is provided with a discharge port 11 for discharging the storage stored in the cylindrical storage tank 2 and / or the rectangular parallelepiped storage tank 6. Reference numeral 12 denotes an inspection manhole in the cylindrical storage tank 2.

  A part of the side wall 4 of the cylindrical storage tank 2 is a partition wall 4a that partitions the cylindrical storage tank 2 and the rectangular parallelepiped storage tank 6. In the vertical direction of the partition wall 4a, the rectangular parallelepiped storage tank 6 side is provided. A plurality of overflow ports 13 are sequentially pierced each time the granular material charged from the inside accumulates in the storage tank 6 (see FIG. 2). On the other hand, each overflow port 13 on the cylindrical storage tank 2 side is directly above each overflow port 13 so that the granule introduced from the cylindrical storage tank 2 side does not overflow to the rectangular storage tank 6 side. Umbrella-shaped members 15 are provided.

  For example, as shown in FIGS. 1 and 2, the passage T formed inside the rectangular parallelepiped storage tank 6 has a zigzag-like drop by alternately arranging a plurality of cereal plates 16. It is good to form in the channel | path T, or to form in the fall channel | path T which arrange | positioned several small hoppers 18 ... continuously in the perpendicular direction, as shown in FIG. Thereby, the beans input from the beans input port 9 of the rectangular parallelepiped storage tank 6 are sequentially guided downward by hitting the cereal plate 16 ... or the small hopper 18 ... and flowing down while the drop impact force is relaxed, Grain cracking, cracking or damage will be prevented.

  1, 2, 3, 5, and the like is a check flap provided in the rectangular machine casing 20. And when the square machine frame 20 which accommodated the rectangular machine frame 17 and the inspection trap 19 which constitutes the outline of the rectangular parallelepiped storage tank 6 are both arranged in the gap between the two adjacent cylindrical storage tanks 2, they are installed. The area can be used effectively.

  The operation of the silo 1 having the above configuration will be described below with reference to FIGS. FIG. 6 is an operation diagram when beans such as red beans and soybeans are fed to the silo 1, and FIG. 7 is an operation diagram when grains such as rice and wheat are fed to the silo 1.

  As shown in FIG. 6, beans that need to prevent cracking, cracking, or damage of grains, such as red beans and soybeans, are fed from a bean inlet 9 at the top of the rectangular parallelepiped storage tank 6. Then, the beans hit the drift cereal plates 16 and flow down while being guided downward. At the bottom of the rectangular parallelepiped storage tank 6, the beans flow along the inclined bottom surface tub 5 and sequentially accumulate on the hopper 3 from the communication port 14. (Refer to FIG. 6A).

  Further, as beans are added, the beans are sequentially deposited on the rectangular parallelepiped storage tank 6 side through the communication port 14 and are filled with beans, but also from the overflow port 13 that overflows to the cylindrical storage tank 2 side. The beans overflow and the cylindrical storage tank 2 is filled with the beans together with the rectangular parallelepiped storage tank 6 (see FIG. 6B).

  Similarly, when the beans are additionally charged, the rectangular parallelepiped storage tank 6 and the cylindrical storage tank 2 are filled with the beans and become near the full amount (see FIG. 6 (c)). As described above, the beans sequentially hit the drift cereal plates 16 and are guided downward and stored while the drop impact force is relaxed, so that cracking, cracking or damage of the grains during grain feeding can be prevented.

  On the other hand, as shown in FIG. 7, grains such as rice and wheat that do not affect the drop impact force from a high place are fed from the grain inlet 7 in the upper part of the cylindrical storage tank 2. And a grain will fall from the height of about 20-30m from the ground, and will accumulate in a mountain shape sequentially from the bottom part of the hopper part 3 (refer Fig.7 (a)).

  An umbrella-like member 15 that covers the overflow port 13 is provided immediately above the overflow port 13. Thereby, even if the accumulation height of the grain gradually increases, the overflow port 13 is blocked by the umbrella-shaped member 15 and does not overflow to the rectangular parallelepiped storage tank 6 side (see FIG. 7 (b)). . Similarly, when additional grains are added, the cylindrical storage tank 2 is filled with the grains and is near the full capacity (see FIG. 7 (c)).

  In addition, when discharging beans or grains, if the discharge port 11 at the lower part of the hopper 3 is opened, it can be discharged outside the machine. At this time, since the inclined surface of the hopper 3 is asymmetrical (one side is longer than the other side by the inclined bottom surface ridge 5), the possibility that the grains form an arch structure is extremely low, It can be quickly discharged from the discharge port 11 at the bottom of the hopper 3.

  As described above, according to the present embodiment, it provides a silo structure capable of selecting and storing grains such as rice and wheat, or beans such as red beans and soybeans, When the beans are stored, grain cracking, cracking or damage can be prevented during grain feeding. And at the time of discharge | emission of a grain, installation of the auxiliary device which blocks | prevents the formation of the arch structure between grains is unnecessary, becomes a strong silo structure, and is very practical.

  The present invention is not limited to the above-described embodiment, and it goes without saying that the configuration can be appropriately changed without departing from the scope of the invention.

  The silo structure of the present invention can provide a silo structure in which grains such as rice and wheat, or beans such as red beans and soybeans can be selected and stored.
