Description

  The present invention relates to a rice washing apparatus, and more particularly to an apparatus for washing rice while feeding rice into a drum and feeding rice in the drum by rotation of feed blades provided on the drum.

  In order to wash a large amount of rice at a time, such as for school lunches, there has been a conventional device for washing rice while putting rice into the drum and pouring water, and feeding rice in the drum by rotation of feed blades provided on the drum. Has been used. In a conventional apparatus, generally, a long and slender drum-like drum and a rotating shaft to which a feed blade is attached along the length direction of the drum are arranged, and the rice is stirred toward the discharge port by the rotation of the feed blade. The method of washing with water poured while being fed was used. For example, Patent Document 1 includes a drum (rice washing tank) in which a single screw (having a spiral feed blade around a rod-shaped rotating shaft) is disposed in the longitudinal direction, and rice is put into the drum. And the rice washing apparatus which can wash | clean rice by performing water injection, stirring and conveying rice to the discharge port (carrying outlet) direction by rotation of a screw is disclosed.

FIG. 14 and FIG. 15 are diagrams showing an example of the structure of a conventional rice washing apparatus, and schematically show a drum and a feed blade disposed therein in the rice washing apparatus. 14 is a perspective view, FIG. 15A is a sectional view taken along line XX in FIG. 14, and FIG. 15B is a sectional view taken along line YY in FIG. As shown in FIG. 14, the conventional rice washing apparatus has an inlet 1402 for introducing rice into the drum 1410 and a plurality of water inlets 1404 (above the drum for injecting water into the drum 1404 ( (Some withdrawal numbers are omitted). The structure in the drum is as shown in FIG. That is, as shown in FIG. 15A, in the conventional apparatus, a single rotating shaft 1516a is passed in the longitudinal direction in a horizontal drum 1510, and a feed blade 1511 that rotates around this is arranged. . Further, the drum was provided with a discharge port 1509 for discharging the washed rice in addition to the input port 1502 for loading rice. Therefore, when washing rice, it is said that the rice is washed by being stirred and conveyed while rotating the feed blade and immersing the rice in water while pouring water through the inlet and rotating the feed blade. The method was taken.
JP-A-11-290704

  However, in the conventional rice washing apparatus, since the rice is stirred and conveyed while being immersed in water as described above, the feed blade 1511 is generally in contact with the inner wall of the drum 1510 as shown in FIG. It was supposed to rotate in the state. For this reason, there is a possibility that the rice being transported may be clogged between the feed blade and the drum and damaged, or may not pass through the feed blade and the drum and remain.

  Further, in the conventional rice washing apparatus, the washing of rice is performed only by water injection. However, in the case of such a rice washing method, there is a problem that a large amount of water is required for washing the rice. In addition, the rice is soaked in the water containing the dirt removed from the rice through almost the entire washing process, and there is also a problem that the rice after removing the dirt absorbs the dirty water again.

  Further, in the conventional rice washing apparatus, as shown in FIG. 15A, the feeding blade 1511 is provided around one rotating shaft 1516a passed through the drum center in the longitudinal direction of the drum 1510. It was provided as a spiral blade. Also, in general, the drum has a structure that cannot be easily disassembled after being assembled as a single cylindrical body in a state where the feed blades are accommodated at the time of manufacture. For this reason, when removing pieces of rice clogged between the feed blades or cleaning the inside of the drum or the feed blades, it is necessary to disassemble the drum into, for example, upper and lower half-cylindrical parts. Even if such disassembly is possible, it is difficult to divide a single spiral blade, and for example, it is not easy to clean between the blades.

  Therefore, the problem to be solved by the present invention is that, firstly, the rice being transported is clogged between the feed blade and the drum and damaged, or the rice cannot be fed through the feed blade and the drum and remains. It is in providing the rice-washing apparatus which does not have a possibility of doing. Secondly, it is an object of the present invention to provide a rice washing apparatus that does not require a large amount of water for washing the rice and that the rice that has been washed does not absorb dirt again.

<Overview>
The rice washing apparatus of this embodiment is a rice washing apparatus having a rotating drum configured by combining two semicylindrical drum halves. Each drum half is provided with a plurality of feed blades, and when the drum halves are combined, the feed blades of one drum half and the feed blades of the other drum half are paired to form a substantially spiral shape. To be. In addition, an input port is provided at one end of the rotary drum, and a discharge port is provided at the other end, and the rotary drum is installed so as to have an upward slope from the input port to the discharge port. Further, the rotating drum has a water-permeable side wall.

  Further, the rice washing apparatus of the present embodiment has a main cleaning pipe that is arranged to penetrate through the pipe space provided by cutting out the feed blades in the rotating shaft region of the rotary drum, and at least the water surface in the pipe-closer pipe space. An immersion tank for immersing the rotating drum so as not to be exposed.

<Configuration>
(General)
The rice washing apparatus of the present embodiment includes a rotating drum, a main washing pipe, and a water bath.
FIG. 1 is a perspective view showing an example of the appearance of the rice washing apparatus of the present embodiment. FIG. 2 is a vertical sectional view taken along line XX of FIG. As shown in FIG. 2, the “rice washing apparatus” 0200 of the present embodiment includes a “rotating drum” 0210, a “main washing pipe” 0220, and a “water bath” 0230.

    (Rotating drum)

  The rotating drum is a cylindrical one configured by combining two semicylindrical drum halves (first drum halves and second drum halves). For example, each center of the upper surface and the lower surface of the cylinder It is held so as to be rotatable about an axis that penetrates through. On the other hand, the plurality of feed blades provided in the rotating drum are fixed to the inner wall of the rotating drum, and no gap is generated between the feeding blade and the inner wall of the rotating drum. Moreover, the feed blade of the rice-washing apparatus of this invention arranges the planar thing. In this respect, the conventional rice washing apparatus shown in FIGS. 14 and 15 has a structure in which the drum itself does not rotate, and the feed blade rotates in a state of being substantially in contact with the inner wall of the drum. A wing is different from a single spiral (thus having a curved surface).

(First drum half)
FIG. 3 shows an example of the shape of the first drum half. As shown in the figure, the “first drum half” 0310a has a semi-cylindrical shape. In the present invention, the “semi-cylindrical shape” refers to a shape obtained by dividing a cylinder into two in the vertical direction with respect to the bottom surface. In addition to a cylinder), a polygonal cylinder (including a substantially polygonal cylinder) whose bottom surface is a polygon (including a substantially polygonal shape) is included. The first drum half in this figure is an example in the case of forming a substantially regular hexagonal cylinder (substantially regular hexagonal column) when a rotary drum is formed in combination with the second drum half. The bottom surface of the half is shaped like a regular hexagon in half. As will be described later, a rotating drum is formed by combining the second drum half on the first drum half.

  The first drum half is provided with a plurality of feed blades. In the example shown in the figure, the first drum half has eight “feed blades” 0311a (a drawer number is given only at one place to avoid complication). Note that the vicinity of the center of the feed blade (rotary shaft region) has a notch portion 0312a (only one place is given a drawing number to avoid complication), and this is a pipe space for penetrating the main cleaning pipe. This is to ensure Details thereof will be described later.

  When these feed blades are combined with the second drum half which is the other half of the drum, they are paired with the feed blades provided on the second drum half so as to be substantially spiral. Arranged diagonally rather than parallel. In the example of this figure, the bottom surface on the discharge port side is closer to the left side surface (side surface appearing at the upper left in the drawing) 0313a of each feed blade than the position contacting the right side surface (side surface appearing at the lower right in the drawing) 0314a. (As will be described later, the rice is transported in the direction of arrow B from the upper right to the lower left of the first drum half in the figure, so the bottom surface on the discharge port side is the bottom surface that appears in the lower left). (An example is shown by the fact that the distance “L1” between the contact position and the bottom surface of one feed blade on the left side surface is shorter than the distance “L2” between the contact position of the feed blade and the bottom surface on the right side surface).

  In the example of this figure, a member 0315a for joining the drum halves is attached to the first drum half. This is for joining the drum halves together with the same kind of member attached to the second drum half, which will be described later, to form a rotating drum.

  The first drum half may be provided with “rotating drum support members” 0350a and 0350a ′ at the ends thereof. Further, a “driven gear” 0360 may be provided at one end. These will be described later in another embodiment.

  Furthermore, as also shown in the figure, a “rice supply pipe” 0302b may be attached to the first drum half. This is a pipe for supplying rice into the rotating drum. Therefore, when the first drum half in the example of the figure is combined with the second drum half to form a rotating drum, the first drum half is supplied into the rotating drum from the inlet of the rotating drum through this rice supply pipe. The rice is washed while being conveyed in the direction of arrow B.

(Second drum half)
FIG. 4 shows an example of the shape of the second drum half. The second drum half also has a semi-cylindrical shape. The “second drum half” 0410b in this figure is for forming a rotating drum in combination with the first drum half shown in FIG. In the same manner as the first drum half shown in FIG. 3, the bottom surface has a substantially hexagonal half shape.

  The second drum half is also provided with a plurality (eight in the example of this figure) of “feed blades” 0411b (with one drawer number attached to avoid complexity). In addition, the vicinity of the center of the feed blade (rotary axis region) has a notch portion 0412b (only one place is given a drawing number to avoid complication), and this is also a pipe space for penetrating the main cleaning pipe. This is to ensure

  Furthermore, when these feed blades are combined with the first drum half, they are arranged so as to form a spiral with the feed blades provided in the first drum half. For this reason, the feed blades of the second drum half are also arranged obliquely rather than parallel to the bottom surface. In the example of this figure, the position in contact with the left side surface (side surface appearing in the upper left in the figure) 0413b of each feed blade is closer to the right side surface (side surface appearing in the lower right in the figure) 0414b. (An example of this is that the distance “M1” between the contact position and the bottom surface of one feed blade on the left side surface is shorter than the distance “M2” between the contact position of the feed blade and the bottom surface on the right side surface). To show)

  Also in the example of FIG. 4, “joining member between drum halves” 0415 b is attached to the second drum half. In addition, the second drum half in the figure also has a “rotating drum support member” 0450b. This will be described later in another embodiment.

  The first drum half and the second drum half need only have a structure and shape that are formed as a rotating drum when the two are combined, so which is the first drum half and which is the second drum half. It does not matter whether, for example, the first drum half may have the shape shown in FIG. 4, and the second drum half may have the shape shown in FIG. Further, for example, the rotating drum support member may be provided only in one drum half.

(Combination of both drum halves)
FIG. 5 is a view showing an example of the shape of a rotating drum formed by combining the first drum half shown in FIG. 3 and the second drum half shown in FIG. In the example of this figure, “second drum half” 0510b is stacked on “first drum half” 0510a, and both drum halves attached to each other are joined to each other. A “rotating drum” 0510 is formed by bonding and fixing. This fixing is preferably performed by simply fitting the joining members of the two drum halves together without screwing or the like so that the two halves can be easily separated and cleaned during use.

  Further, in the example of this figure, by this combination, the “rotating drum support member” 0550a on the bottom surface (appearing in the upper left in the figure) on the discharge port side of the first drum half and “ "Rotating drum support member" 0550b is overlapped to form a "rotating drum support member" 0550 that surrounds the entire circumference of the bottom surface of the rotating drum. On the other hand, the “rotating drum support member” 0550a ′ on the bottom surface on the inlet side (appearing in the lower right in the figure) is attached to the first drum half. These “rotating drum support members” are members for rotatably supporting the rotating drum by, for example, a roller portion (not shown) provided in the rotating drum housing case, and the material thereof is, for example, resin. A specific example is silicon resin.

  Further, in the example of this figure, a “driven gear” 0560 is provided on the outer side of the rotary drum support member on the input port side. This "driven gear" meshes with a drive gear (not shown) provided on the drive device side that drives to rotate the rotary drum, and transmits the rotation transmitted from the drive gear to the rotary drum. It is for rotating this. Details of this configuration will be described later in another embodiment.

(Relationship of feed blades)
Next, the arrangement relationship of the feed blades of the first drum half and the second drum half will be described.
FIG. 6 is a conceptual diagram for explaining the positional relationship between the feed blades of the first drum half and the second drum half, and when these two drum halves are combined, the feed provided to each of them is shown. It is typically shown that the blades are arranged so as to form a spiral in pairs. Among these, (a) shows the second drum half, (b) shows the first drum half, and (c) shows the combined state of the first and second drum halves. Since this drawing is only for explaining the concept, the number of feeding blades provided in each half of the drum is six, and in order to avoid the complexity of the drawing, a notch near the center of the feeding blade is used. Illustration is omitted. For the same reason, only the upper end surface of the feed blade is shown in (c).

  In the example shown in the figure, the six feeding blades of the “second drum half” 0610b shown in (a) are respectively between aa ′, bb ′, cc ′, and dd. The six feed blades of “first drum half” 0610a shown in (b) are arranged between gg, gh, and hh, respectively. Between ', ii', jj ', kk', and l '. Therefore, the second drum half was turned upside down, and the two drum halves were combined to form a “rotating drum” 0610 as shown in FIG. In this case, the feed blade provided in the second drum half is formed in a substantially spiral shape in a pair with the feed blade provided in the first drum half.

  As a result of the arrangement relationship of the feed blades, the rice put into the rotating drum rotates instead of being conveyed in the drum while being stirred by the rotation of the feed blades as in the conventional apparatus. The drum is transported through the drum while repeatedly rising and falling. That is, in the example of FIG. 6, first, in the state of (c), the rice is fed between the feed blade passed between gg ′ on the first drum half side and the feed blade passed between hh ′. If it is put in between, the rotating drum rotates counterclockwise (arrow C direction), so that the rice is pushed out by the feed blades passed between gg ′ and the discharge port direction (arrow B direction). Proceed to When the rotating drum is in the shape of a polygonal cylinder (polygonal prism) as in the example of this figure, as the rotating drum rotates, the rice on the side surface located on the floor portion in the rotating drum is rotated by the rotating drum. The floor is gradually tilted with the inclination of the floor, and it will eventually be unable to withstand the inclination and will drop at once. And when it rotates 120 degree | times from the state of (c), since the side surface of a 2nd drum half body turns into a floor surface, rice falls at this time to the 2nd drum half body side. At that time, most of the rice falls between the feed blades passed between aa ′ on the second drum half side and bb ′.

  Next, when the rotating drum further rotates, the rice between the feeding blades passed between aa ′ and the feeding blades passed between bb ′ on the second drum half side becomes aa ′. It proceeds in the direction of the discharge port (in the direction of arrow B) while being pushed out by the feed blades passed in between. Then, following the same progress as described in the previous paragraph, the rice will eventually be unable to withstand the inclination and will fall at once. At this time, most of the rice between the feed blades passed between aa ′ and the feed blades passed between bb ′ was passed between hh ′ on the first drum half side. It falls between the feed blades passed between the feed blades and ii ′.

  Furthermore, the rice between the feed blades passed between hh ′ on the first drum half side and the feed blades passed between ii ′ is between hh ′ as the rotating drum rotates. Advancing in the direction of the discharge port (in the direction of arrow B) while being pushed out by the feed blade in the direction of the discharge port, most of the rice is passed between bb 'on the second drum half when it can no longer withstand the inclination. It falls at a stretch between the feed blades passed between the feed blades and cc ′. By repeating such a process, the rice is gradually conveyed toward the discharge port.

  In the example of this figure, when the rotating drum makes one revolution, most of the rice between the feeding blades passed between aa ′ and the feeding blades passed between bb ′ is bb ′. This is a preferred example of moving between the feed blades passed in between and the feed blades passed between cc ′ to the next adjacent space across the feed blades. This is because it is possible to wash the rice by rubbing the rice at this time by dropping the rice at a stroke as described later, but by rubbing the rice little by little in this way, This is because rice can be washed more appropriately by increasing the number of opportunities for matching. However, the structure of the rotating drum according to the present embodiment is not limited to the structure in which the feed blade is separated and conveyed to the next adjacent space as described above. As for the positional relationship between the feed blades and the feed drums of the second drum half, when the rotating drum makes one rotation, most of the rice is conveyed across the feed blades while moving almost evenly to the next and second adjacent spaces. It may be arranged so as to follow.

  In this way, the structure of the rotating drum is such that the rice is transported through the drum while repeatedly rising and falling in the drum where the rice rotates, so that the rice is agitated by the rotation of the feed blade as in the conventional apparatus. However, unlike the structure that is transported in the drum, it eliminates the possibility of rice clogging between the feed blade and the drum and being damaged, or being unable to pass through the feed blade and the drum and remain. Can do.

(Main wash pipe)
Next, in the rotating drum of the present embodiment, the main cleaning pipe is disposed through the pipe space provided by cutting out the feed blade in the rotating shaft region of the rotating drum.

  The “main cleaning pipe” is a device for injecting water toward the rice for cleaning the rice being conveyed in the rotary drum. In the present invention, the main washing pipe is characterized in that it is arranged in a space penetrating the substantially central portion of the rotating drum. In this respect, the conventional rice washing apparatus shown in FIGS. This is different from the case where water is poured into rice that is being stirred and conveyed from here.

  FIG. 7 is a diagram illustrating an example of the shape of the “main cleaning pipe” 0720. In the example of this figure, the right direction is the inlet side of the rotating drum and the left direction is the outlet side of the rotating drum, and the washing water flows through the pipe from left to right. Since the washing water is pumped from the washing water tank by a pump, it is taken in from the left end of the main washing pipe.

  The “main cleaning pipe” is used to inject water toward the rice in order to wash the rice being transported in the rotating drum and to wash off the rice adhering to the ceiling of the rotating drum. Part 0723 (a drawer number is given only at one place to avoid complication). It is desirable that the injection unit is an injection nozzle. Although the example of this figure also shows what an injection | pouring part is an injection nozzle, details, such as the objective of setting it as an injection nozzle and the shape of an injection nozzle, are mentioned later in another Example.

  The main cleaning pipe is disposed through the pipe space and is rotatably held by, for example, a bearing portion provided in each half of the drum constituting the rotating drum. That is, the “pipe space” is a space for disposing the main cleaning pipe, and specifically, is provided by cutting out the feed blades in the rotating shaft region of the rotating drum.

  FIG. 8 is a diagram for explaining an example of an arrangement relationship between the main cleaning pipe and the rotating drum, and “second drum half” 0810b, “main cleaning pipe” 0820, and “first drum half” 0810a. Is shown in a separated state. Although not clearly shown in the figure, the “feed blade” 0811a provided in the “first drum half” constituting the rotating drum has a substantially semicircular shape having a diameter near the center of the upper edge. Although the portion 0812a is notched and does not clearly appear in the drawing, the feed blade 0811b of the “second drum half” is similarly a semicircular portion 0812b having a diameter near the center of the upper edge. The part is cut away (the cutout positions and shapes of the feeding blades of both halves are clearly shown in FIGS. 3 and 4). The main cleaning pipe is disposed through the pipe space (generally surrounded by the broken line oval 0821) provided by cutting out the feed blade in the rotating shaft region of the rotating drum (note that the rotating drum and the main cleaning pipe) An example of the position of the pipe space in the assembled state is shown later using FIG. 2).

  In the example of FIG. 8, “bearing portions” 0816 (some of which do not appear in the drawings) are provided on both the inlet and outlet sides of the first drum half and the second drum half. The main cleaning pipe is rotatably held by the bearing portion. In such a structure, since the main cleaning pipe is only on the bearing portion, the main cleaning pipe can be easily removed when the rotating drum is disassembled into two drum halves for cleaning and the like. Disassembly for cleaning and the like becomes easier.

  The reason why the main cleaning pipe is rotatably held is that the main cleaning pipe is fixed to the conduit so that the main cleaning pipe does not rotate together with the rotation of the rotating drum. Further, by adopting such a structure, it is possible to keep the injection direction of water injected from the main cleaning pipe constant.

(Immersion tank)
Next, the rice washing apparatus of the present example is installed so that the rotating drum has an upward slope from the inlet to the outlet, and in this respect, in conventional rice washing apparatuses, the drum is generally set horizontally. Is different.

  The purpose of such a structure is to store water in a submerged tank provided in the lower part near the inlet of the rotary drum and soak rice in the initial stage of conveyance there. This is because the soil lightly adhering to the surface of the rice is first removed by immersing the rice in the initial stage of washing the rice.

  Further, in order to make it possible to immerse the rice put into the rotating drum in the water of the submerged tank while being stored in the drum, the rotating drum of this embodiment has a water-permeable side wall. . One example thereof is a side wall in which an infinite number of small holes 0810c are formed in a metal plate (in this figure, small holes are shown only on a part of one side surface of the second drum half for convenience, but the side surface of the second drum half is shown. ), All other side surfaces and the entire surface of the second drum half are also drilled. In addition, a small hole (slit) 0810d (a drawer number is given only at one place to avoid complication) provided in the side surface of the drum half is for fixing the feed blade to the rotating drum.

  Further, the submerged tank is configured to submerge the rotating drum so that the water surface does not cover at least the space for the pipe closer to the inlet. This is because when the water surface reaches such a position, the upper end of the feed blade is buried in the water, and the rice climbs over the upper end of the feed blade in the water and directly adjacent to the same drum half. This is because there is a possibility of moving to a section (a space sandwiched between adjacent feed blades). Therefore, by configuring as described above, the rice is smoothly transferred from one drum half to the other drum half, and the process in which the rice is transported through the drum while repeatedly rising and falling is smoothly advanced. It becomes possible.

  FIG. 9 is a conceptual diagram showing a state where rice b is immersed in water a stored in the “immersion tank” 0930. The rice washing apparatus of this example has the same structure as that shown in FIGS. 1 and 2, and the details thereof will be described later with reference to these drawings. In this figure, the rotating drum of the rice washing apparatus is accommodated. The rice put in from a case input port 0902 provided in a case (rotary drum storage case) 0901 for supplying is supplied into the rotary drum 0910 from the input port 0917 through the rice supply pipe 0902b. Since the rotating drum is installed so as to have an upward slope from the inlet to the outlet 0918, the rice b is accumulated near the inlet of the rotating drum at the initial stage of conveyance. On the other hand, the water a accumulated in the submerged tank penetrates into the rotating drum through the water-permeable side wall of the rotating drum. As a result, the state in which the rice in the rotating drum is immersed in water at the initial stage of conveyance is realized.

  When performing rice washing using the rice washing apparatus of the present invention, as described above, the method of immersing the rice at the initial stage of conveyance as described above, and washing the rice by pouring water until the rice is immersed in water in the subsequent process Is not used. As will be described later, a main cleaning pipe is provided penetrating the region from the vicinity of the inlet to the outlet in the rotating drum, from which a small amount of water is jetted. Another reason is to send the rice to the outlet without any delay. Moreover, you may use in order to wash away the residual rice adhering in a drum. And in the washing of rice except for the initial stage of conveyance, a method of friction between rice is also used. By doing so, it is possible to avoid a situation in which dirty rice once again absorbs dirty water.

  In this way, the water tank is configured to submerge the rotating drum so that the water surface is not exposed to at least the inlet-side pipe space 0921, so that the rice alternates from one drum half to the other drum half. While being moved, the drum is transported in the drum while repeatedly rising and falling between a plurality of feed blades 0911 (partially attached with drawer numbers to avoid complications) provided to be substantially spiral. Is possible.

(Other)
In addition to the above, the rice washing apparatus according to the present embodiment may include a rotating drum housing, a washing water tank, a rice washing receiving tank, a support frame, and the like.

  The rice washing apparatus shown in FIG. 1 is also an example having such a configuration. In other words, the “rice washing apparatus” 0100 in the figure includes a “rotating drum housing case” 0101, a “washing water tank” 0103, a “rice washing tank” 0104, and a “support frame” 0105 for supporting the above members. Etc.

  The “rotary drum storage case” is a case for storing a rotary drum (not shown in the figure) inside. The rotating drum housing case has a “frame input port” 0102 for inputting rice into the rotating drum. In addition, the rotating drum storage housing also serves to prevent water sprayed from the main cleaning pipe from penetrating through the small holes formed in the rotating drum.

  The “washing water tank” is a tank for storing water to be used for washing rice. The water stored here is pumped up through a conduit 0106 by, for example, a pump (not shown in the figure), injected into a rotating drum, and used for washing rice. In addition, the “washing water tank” is a tank filled with rice that has been washed and collected in the rice washing tank with the pressure of the pump (may be part of the rice washing device or provided outside the rice washing device). It does not preclude taking on the role of storing wash water used for sending with water. The “filling bar” is an apparatus for immersing the washed rice in water for a predetermined time.

  The “rice washing tank” is for receiving rice discharged from the rotating drum after washing.

  As described above, the “support frame” is for supporting each member such as the rotating drum housing case, the washing water tank, and the rice washing tank. At the same time, it also serves to provide a space for arranging the pump and the conduit. I'm in charge.

  FIG. 2 is an XX vertical cross-sectional view of the rice washing apparatus shown in FIG. 1 (the XX line is a line appearing at the height of the casing input port 0102). However, the support frame, the pump, and the conduit have shown the appearance that appears on the front view (viewed in the direction A in FIG. 1) for convenience. With reference to this figure, the rotating drum storage housing, the washing water tank, the rice washing receiving tank, and the support frame described in FIG. First, a “feeding hopper” 0207 is provided under the “cassette inlet” 0202 of the “rotary drum storage case” 0201 of the “rice washing apparatus” 0200 in this figure, and this temporarily puts the rice introduced from the cabinet inlet. Fulfill the role of saving. Further, the rice stored in the charging hopper is supplied from the “loading port” 0217 into the “rotating drum” 0210 through the “rice supply pipe” 0202b provided below the rice. Further, the cleaned rice is discharged from the “housing outlet” 0209 to the “rice-washing tank” 0204.

  On the other hand, the cleaning water is stored in a “washing water tank” 0203, pumped out by a “pump” 0208, and pumped up for injection into a rotating drum through a “conduit” 0206. Moreover, the example of this figure is used for the washing water tank to send the rice collected in the rice washing receiving tank after washing together with water to the filling bar provided outside the rice washing apparatus by the pressure of the pump. This is an example of the role of storing wash water. Therefore, the conduit of this example includes a conduit portion 0206a for pumping water from the washing water tank by a pump, a conduit portion 0206b for taking out the rice from the washing rice receiving tank, and a conduit portion for draining the water in the washing water tank. 0206c.

  Further, in this figure, the “main cleaning pipe” 0220 is disposed penetrating through a “pipe space” (generally surrounded by a broken line oval 0221) provided by cutting out the “feed blade” 0211 in the rotation axis region. ing.

  In addition, the rice washing apparatus of the present embodiment may have a “finish washing pipe”. The finish cleaning pipe is disposed near the discharge port of the rotary drum, and is for injecting clean water onto the rice that has been almost cleaned. In addition, it is possible to prompt the rice to be smoothly discharged toward the washed rice receiving tank without adhering to the vicinity of the discharge port of the rotating drum. The clean water sprayed from the finish cleaning pipe is stored in the cleaning water tank and can be reused as cleaning water.

  Moreover, the rice washing apparatus of a present Example may have a "remaining rice washing pipe". The remaining rice washing pipe is for injecting water to wash off the rice adhering to the ceiling of the rotating drum. In the case where a remaining rice cleaning pipe is provided, the main cleaning pipe can specialize its function in jetting for cleaning the rice.

<Effect>
According to the invention of this embodiment, there is no possibility that the rice being transported will be clogged between the feeding blade and the drum and damaged, or the rice washing cannot pass through the feeding blade and the drum and remain. Can be provided. In addition, it is possible to provide a rice washing apparatus that does not require a large amount of water for washing the rice and that the rice that has been washed does not absorb dirt again. Moreover, it becomes possible to provide the rice washing apparatus which can remove first the stain | pollution | contamination lightly adhered to the surface of the rice by immersing the rice in the initial stage of the rice washing. Furthermore, it is possible to provide a rice washing device that can easily disassemble the drum and the feed blades, and can easily perform cleaning between the blades.

<Overview>
The rice washing apparatus of the present embodiment is basically in common with the rice washing apparatus of the first embodiment. However, the rice washing apparatus of the present embodiment is characterized in that the rotating drum is rotated by the driving force transmitted from the driving gear and has a roller portion that detachably supports the rotating drum.

<Configuration>
(General)
FIG. 10 is a diagram showing an example of the configuration of the rice washing apparatus according to the present embodiment, in which the rotating drum and its peripheral devices are viewed from the horizontal direction with respect to the rotating drum from the inlet side of the rotating drum (the arrow in FIG. 3). FIG. 2 schematically shows a state seen in the D direction).

(Roller part)
The “rotating drum” 1010 of this example also has a substantially regular hexagonal bottom surface, and is rotatably held around a “rotating shaft” 1011 in a rotating drum housing (not shown). At this time, a “rotating drum support member” 1050 is attached to the rotating drum, and the rotating drum is roller-supported by a “roller portion” 1070 via the rotating drum support member. An example of the shape of the roller portion is as shown in FIG. That is, the roller unit 0270 is, for example, a cylindrical shape, and is provided in the rotating drum storage housing 0201.

  The roller unit detachably supports the rotating drum. In other words, the roller portion provided in the rotating drum housing case simply carries the rotating drum. Therefore, the rotary drum can be easily detached from the rotary drum housing and disassembled for cleaning or the like.

(Driven gear)
The rotating drum of this example includes a “driven gear” 1060 that meshes with a “driving gear” 1061 provided in the rotating drum housing. Therefore, for example, when the driving gear rotates counterclockwise by driving the motor, the driven gear that meshes with the driving gear rotates clockwise by the driving force transmitted from the driving gear, and is attached to the rotating drum and this accordingly. The rotating drum support member also rotates clockwise because it is supported by the roller portion. In this case, the roller portion rotates counterclockwise. The rotation direction of the drive gear and the like in this figure corresponds to the case where the direction of the feed blades arranged obliquely with respect to the bottom surface is the example shown in FIGS. When the rotational direction of the driven gear and the like is opposite to that in the example in the figure, the feeding blade is arranged in the direction opposite to that in FIGS. 3 and 4 in order to push the rice in the direction of the discharge port as the rotating drum rotates. The

  An example of the shape of the driven gear and the rotating drum support member is as shown in FIGS. Although not appearing in FIG. 10, the rotating drum support member and the roller portion are also provided near the bottom surface on the discharge port side of the rotating drum. In the example of FIGS. 3 to 5, the rotating drum support member 0350 a ′ on the inlet side is attached to the first drum half, and the outlet 0350 a ′ is attached to the first drum half. The driven gear 0360 is attached to the first drum half, and the rotating drum support member and the driven gear are attached to which drum half. It may be. For example, unlike the examples of FIGS. 3 to 5, the rotating drum supporting member on the bottom surface A side is attached to one of the drum halves or the rotating drum supporting member on the inlet side is the second. A structure such as being attached to the drum half may be used. In short, any material can be used as long as it can be formed into a shape as shown in FIG.

  In this way, by configuring the rotating drum to rotate by the driving force transmitted from the driving gear, the drum itself does not rotate as in the conventional apparatus, and the state where the feed blade is almost in contact with the inner wall of the drum Unlike the case where rice is stirred and conveyed while rotating at, a mechanism can be realized in which the rotating drum itself rotates to convey rice while repeatedly rising and falling in the drum.

<Effect>
According to the present invention, the rotating drum can be easily detached from the rotating drum housing and disassembled for cleaning and the like. In addition, it is possible to realize a mechanism in which the rotating drum itself rotates to convey rice while repeatedly rising and falling in the drum.

<Overview>
The rice washing apparatus of the present embodiment is basically the same as the rice washing apparatus of the first embodiment. However, the rice washing apparatus of the present embodiment is characterized in that the main washing pipe has an injection nozzle, and the injection nozzle is disposed obliquely upward.

  <Configuration>

(General)
An example of the shape of the main washing pipe of the rice washing apparatus of the present embodiment is as shown in FIG. That is, the “main cleaning pipe” 0720 of the present embodiment has an “injection portion” 0723 for injecting cleaning water toward the rice being conveyed, as an injection nozzle. Further, the injection nozzle is disposed obliquely upward. Furthermore, it is desirable that the injection port of the injection nozzle be inclined so that the cleaning water is injected at a wide angle in a substantially vertical direction with respect to the edge portion forming the pipe space of the feed blade. “Nozzle” generally refers to a cylindrical device having a thin tip for jetting fluid at high speed. In the present invention, the nozzle has a fan-like jet port whose tip is thinned only in the front-rear direction and wide in the left-right direction. Refers to the device. Therefore, its function is not to inject water at high speed, but to inject water over a wide range.

  The washing water sprayed from the spray nozzle outlet does not spread in the front-rear direction, but spreads in the left-right direction at the fan angle in the left-right direction of the spray nozzle (about 100 degrees in this example), and a small amount of washing Water can be sprayed over a wide area.

(Arrangement direction of injection nozzle)
Moreover, the injection nozzle of the present embodiment is disposed obliquely upward.
FIG. 11 is a diagram illustrating a preferable example of the injection direction of the injection nozzle. This figure schematically shows the state of the main cleaning pipe and its peripheral devices as viewed from the horizontal direction with respect to the main cleaning pipe from the inlet side of the main cleaning pipe (in the direction of arrow D in FIG. 2). It is.

  In the preferred example of this figure, the “injection nozzle” 1123 of the “main cleaning pipe” 1120 is arranged obliquely upward by about 20 degrees. As a result, the cleaning water sprayed from the spray nozzle can be distributed to the ceiling of the rotating drum or the like. Combined with this jet and gravity, it is possible to wash off the rice adhering to the ceiling. If the upward angle of the spray nozzle is too large, water or rice sprayed near the ceiling may fall on the main cleaning pipe directly below, which is not preferable. The angle of about 20 degrees obliquely upward is also in consideration of such circumstances.

(Inclination direction of injection nozzle)
Moreover, it is desirable that the injection port of the injection nozzle be inclined so that the cleaning water is injected at a wide angle in a substantially vertical direction with respect to the edge portion forming the pipe space of the feed blade.

  FIG. 12 is a view for explaining the relationship between the edge of the feed blade and the direction of the injection port. In the figure, for convenience of explanation, only the direction of the feed blade and the injection port is schematically shown together with the relative positional relationship. The “edge part forming the pipe space of the feed blade” 1212 is an edge part on an arc formed by cutting out the vicinity of the center of the feed blade 1211. The injection port 1223 is disposed substantially at the center of a circle including the arc that forms the edge. “Inclined so that the cleaning water is sprayed at a wide angle in a direction substantially perpendicular to the edge” is just an example of the spray nozzle provided in the main cleaning pipe shown in FIG. It is attached in such a direction that water is sprayed at a wide angle from the side to the vertical direction. In addition, the reason why the spout is inclined slightly rather than horizontally (in the example of FIG. 12 is slightly inclined to the right) is to allow the sprayed water to spread over a wider range. Furthermore, since the feed blades are arranged obliquely, the position where the injection is received shifts as the rotating drum rotates (in the example of this figure, it shifts to the left). It becomes possible to continue spraying water to the edge.

  As shown in the examples of FIGS. 7 and 8, the inclination directions of the injection ports are preferably arranged so that the right-down and right-up directions are alternately arranged. This is to reduce the blind spot in the range where the injection can reach and to spread the water over a wider range.

(Water injection direction)
FIG. 13 shows an example of the direction in which water is ejected when the ejection nozzles are arranged in the preferred arrangement direction and the inclination direction described above. The injection port of the injection nozzle of this figure is an example of what inclines slightly rightward seeing from the direction of FIG. FIG. 13A shows the main washing pipe 1320 and the injection nozzle 1323 in the state seen from the same direction as FIG. 11, and shows the general direction of water injected from the injection nozzle by hatching. Moreover, FIG.13 (b) shows the right view when FIG.13 (a) is made into a front view, FIG.13 (c) shows a top view similarly. Although the injection nozzle does not appear in FIG. 13B, when viewed from this direction, the injection port of the injection nozzle is inclined slightly upward. As shown in these figures, when the injection nozzle is arranged in the preferred arrangement direction and the inclination direction described above, the water hardly spreads up and down around the direction of 20 degrees above, but just on the discharge port side. While having a slightly higher slope on the inlet side, the cleaning water is sprayed at a wide angle with a spread of about 100 degrees to the left and right in a direction substantially perpendicular to the edge forming the pipe space of the feed blade. Become.

(Purpose of this configuration)
The purpose of the configuration of the present embodiment is to make it possible to spray a small amount of washing water so as to spread over a wide range. In addition, the washing water is not sprayed intensively toward the rice with a strong momentum, but it is not so strong and with a large momentum, the purpose of the injection in this embodiment is the same as the conventional device. In order to remove the dirt on the surface of the rice and wash away the rice remaining in the rotating drum without being transported to the discharge port. It is. In the rice washing apparatus of the present embodiment, the removal of dirt on the surface of the rice is mainly performed by friction between the rices, and is used to remove dirt by jetting water. Small amount is enough. In addition, it is considered that the remaining rice often adheres to the ceiling part of the rotating drum and the feed blade. Therefore, the spray nozzle is disposed obliquely upward, and the direction of the spray port is the edge that forms the space for the pipe of the feed blade. By making the portion substantially perpendicular to the portion, the rice adhering to the above position can be easily washed off.

<Effect>
According to the invention of the present embodiment, the washing water can be sprayed over a wide range from the main washing pipe, and a small amount of water used for washing the rice can be used. It becomes possible to easily wash off the adhered residual rice.

<Overview>
The rice washing apparatus of the present embodiment is basically the same as the rice washing apparatus of the third embodiment. However, the rice washing apparatus of the present embodiment has an umbrella part arranged at the upper part of the main washing pipe at a distance higher than the protruding height of the injection nozzle, and is provided in the rotating drum and is slid in the vicinity of the umbrella part. It has a feature in that it has a swab to remove the adhered residual rice.

<Configuration>
(General)
An example of the shape of the main washing pipe of the rice washing apparatus of the present embodiment is as shown in FIG. That is, the rice washing apparatus of the present embodiment has an “umbrella portion” 0780 disposed above the “main washing pipe” 0720 and spaced apart by a protruding height of the “injection nozzle” 0723. Moreover, an example of the shape of a part of the rotating drum of the rice washing apparatus of the present embodiment is as shown in FIG. This figure is an example of the shape of the second drum half, but the rice washing apparatus of the present embodiment is provided in such a rotating drum and is slid in the vicinity of the umbrella part to remove residual rice adhering to the umbrella part. "Sticker" 0490.

(Umbrella part)
The “umbrella portion” is disposed above the main cleaning pipe at a distance higher than the protrusion height of the injection nozzle. The main cleaning pipe is installed so as to penetrate through the center of the space where the rice is transported as it rises and falls repeatedly. When washed off, the rice may adhere to the main washing pipe again. However, the rice adhering to the main cleaning pipe itself cannot be washed away with the cleaning water sprayed from the main cleaning pipe. Therefore, it can be considered that the rice is removed by a method of paying with a stick. However, when the main cleaning pipe has an injection nozzle, unevenness is generated on the surface of the main cleaning pipe, and it is difficult to easily pay this with a swab. Therefore, in the rice washing apparatus of this embodiment, an uneven umbrella portion is arranged on the upper part of the main washing pipe, the rice to be attached to the main washing pipe is attached here, and this can be easily wiped off with a swab. It is what I did.

  As shown in FIG. 7, the “umbrella portion” 0780 of this embodiment is disposed on the upper portion of the “main cleaning pipe” 0720. Further, at that time, they are arranged apart from the projection height of the injection nozzle. Otherwise, the umbrella portion cannot be made a surface without unevenness. Further, when the rice adhering to the ceiling of the rotating drum is washed away, the umbrella portion is arranged in the horizontal direction of the injection nozzle in order to prevent the rice from adhering again to the main washing pipe, particularly the injection nozzle which is the protruding portion. It is desirable to project to at least the same position as the projecting width to.

  An example of the position of the “umbrella” is as shown in FIG. In this figure, the “umbrella portion” 1180 is disposed above the “main cleaning pipe” 1120 at a distance higher than the protrusion height of the “injection nozzle” 1123, and at the same position as the protrusion width in the horizontal direction of the injection nozzle. The state of overhanging is shown. In this figure, the position of the “sticker” 1190 is also shown. As will be described later, the sticker in the example of this figure is fixed to the “rotating drum” 1110 and fixed around the main cleaning pipe. It is configured to rotate at an altitude. Specifically, this altitude is set to match the height of the umbrella. Therefore, the “umbrella portion” in the figure has an arcuate cross section.

(Sticker)
The “sticker” is provided on the rotating drum and is slid in the vicinity of the umbrella part to remove the remaining rice adhering to the umbrella part.

  In the example shown in FIG. 4, the “dispenser” of this embodiment is attached to the bearing portion 0416 of the second drum half 0410 b in the form shown in FIG. 4. Therefore, when the rotating drum rotates around the rotation axis, the “paying rod” rotates along an arc around the rotation axis.

  An example of the position of the wand is as shown in FIG. In this figure, the “paying stick” 1190 is positioned so as to be substantially in contact with the upper portion of the “umbrella portion” 1180. As described above, since the umbrella portion in the figure has an arc shape, the rice sticking on the umbrella portion can be wiped off by the circumferential movement of the swivel rod around the rotating shaft 1116a. It becomes possible. Note that “sliding in the vicinity of the umbrella portion” includes not only the case where the wand moves around the umbrella portion without contacting the umbrella portion as in the example of FIG. This includes the case where the circumference moves around.

<Effect>
According to the invention of this embodiment, there is provided a rice washing apparatus in which rice to be attached to a main washing pipe is attached to an umbrella portion provided on the upper part of the main washing pipe and can be easily removed with a stick. Can do.

<Overview>
The rice washing apparatus of this embodiment is basically the same as the rice washing apparatus of the first embodiment. However, the rice washing apparatus of the present embodiment is characterized in that the submerged tank is configured to submerge the rotary drum so that the water surface does not cover the charging port provided in the rotary drum.

<Configuration>
The configuration of this embodiment will be described with reference to FIG. This figure schematically shows a configuration in which the rotating drum is submerged so that the water surface does not cover the charging port 0917 provided in the rotating drum. In this figure, water is stored in an “immersion tank” 0930 provided below the “rotating drum” 0910 in the “rotating drum housing case” 0901. The water accumulated in the submerged tank penetrates into the rotating drum through the water-permeable side wall of the rotating drum. As a result, part of the water is also filled in the portion near the inlet of the rotating drum, and a state in which the rice in the rotating drum is immersed in water at the initial stage of conveyance is realized.

At this time, if the surface of water penetrating into the rotating drum from the submerged tank hits the inlet, the water penetrates into the supply pipe, the supply pipe gets wet with water, and the rice tends to adhere to the rotation. There is a risk that rice will not be smoothly fed into the drum. Therefore, in this embodiment, the submersion tank is configured to submerge the rotary drum so that the water surface does not cover the inlet provided in the rotary drum. Specifically, for example, it is assumed that innumerable small holes are formed on the entire surface of the side surface of the rotating drum such as a metal net. In this way, even if the water level in the rotating drum temporarily reaches a position higher than the water level of the submerged tank due to the cleaning water sprayed from the main cleaning pipe, this level of water before the bottom reaches the lower end of the inlet. It is possible to drain the overflowed water to the flooding tank through the metal net, etc., and as long as the water level in the flooding tank is kept below the lower end of the loading port, the water level should not be applied to the loading port. Can be secured.
Further, in order to make it possible to immerse the rice put into the rotating drum in the water of the submerged tank while being stored in the drum, the rotating drum of this embodiment has a water-permeable side wall. . One example thereof is a side wall in which an infinite number of small holes 0810c are formed in a metal plate (in this figure, small holes are shown only on a part of one side surface of the second drum half for convenience, but the side surface of the second drum half is shown. ), All other side surfaces and the entire surface of the second drum half are also drilled. In addition, a small hole (slit) 0810d (a drawer number is given only at one place to avoid complication) provided in the side surface of the drum half is for fixing the feed blade to the rotating drum.

<Effect>
According to the invention of this embodiment, water that has permeated into the rotating drum does not enter the inlet, and rice can be supplied smoothly into the rotating drum.

<Overview>
The rice washing apparatus of this embodiment is basically the same as the rice washing apparatus of the first embodiment. However, the rice washing apparatus of the present embodiment is characterized in that the rotating drum is polygonal.

<Configuration>
“The rotating drum is polygonal” means that the bottom surface of the rotating drum is polygonal and the rotating drum is a polygonal cylinder (polygonal column). The purpose of making the rotating drum polygonal is to make the rice rise and fall more smoothly in the rotating drum. That is, when the rotating drum is a cylinder, the rice in the rotating drum gradually falls with the rotation of the rotating drum, whereas when the rotating drum is a polygonal cylinder, it is positioned on the floor portion in the rotating drum. The rice on the side is gradually tilted with the tilt of the floor surface as the rotating drum rotates, and eventually falls off at a stretch because it cannot withstand the tilt. By dropping the rice at a stroke in this way, it becomes possible to wash the rice by rubbing the rice.

  The number of corners of the polygon does not matter, but if the number is too large, it will not be much different from the cylinder, and the advantage of making the rice rise and fall even smoother will be diminished. In view of the structure and function of the rotary drum described above, it is desirable that the number of angles is an even number. A suitable example is a hexagon.

<Effect>
According to the invention of the present embodiment, it is possible to provide a rice washing apparatus capable of performing rice rising and falling in the rotating drum more smoothly.
