Description

The present invention relates to a weighing rice bin.

Conventionally, weighed rice bins that store rice and weigh the stored rice and take it out to a predetermined container have been known.

For example, in Patent Document 1, a storage chamber for storing rice, a drop opening formed on the bottom surface of the storage chamber for dropping rice from the storage chamber, and a drop opening provided below the drop opening correspond to a certain amount of rice. A rice box having a rotating measuring box having a volume and a measuring unit operating means for operating the rotating measuring box is disclosed. The rotary measuring box has a cylindrical shape and is rotatably supported by the side wall of the cabinet constituting the rice box body. Specifically, the rotary measuring box is fitted with a mass support shaft that penetrates the inside of the rotary measuring box along the center line, and both ends of the mass support shaft in the axial direction are formed on the side wall of the cabinet. It is inserted and supported in the hole. The measuring unit operating means rotates and operates the rotary measuring box. The rotary measuring box is formed with an opening that can communicate with the drop opening.

In the rice box configured in this way, when the rotary measuring box is placed at a position where the opening of the rotary measuring box faces upward and faces the drop opening, rice is passed through these openings and the drop opening to the inside of the rotary measuring box. Is introduced. On the other hand, when the rotary weighing is rotated so that the opening of the rotary measuring box faces downward, a certain amount of rice is dropped from the rotating measuring box through these openings into a container arranged below the rotating measuring box. ..

In this rice box, since the rotating shaft penetrates the inside of the rotating measuring box for measuring rice, there arises a problem that rice is not smoothly introduced into the rotating measuring box and proper weighing becomes difficult. Further, the rice box is required to easily take out the rotary measuring box from other members for maintenance and cleaning, but in the rice box of Patent Document 1, the mass support shaft and the side wall are released from the mating. Furthermore, it is necessary to pull out this mass support shaft from the side wall of the cabinet, and there is a problem that disassembly is not easy.

On the other hand, Patent Document 2 discloses a rice bin in which a shaft portion is provided on the outside from the main body portion of the box member for measuring rice and the box member is detachably attached to the rice box main body.

Specifically, Patent Document 2 includes an upper body having a drop port for storing rice and dropping the stored rice, and a lower body provided below the upper body. , A measuring box having a volume corresponding to a certain amount of rice, a lower housing that rotatably supports the measuring box, an operating member for rotating the measuring box, and a container for receiving the rice measured by the measuring box are provided. Weighed rice bins have been disclosed.

The measuring box has a main body portion having a substantially cylindrical shape and a predetermined space inside, and a substantially cylindrical shaft portion extending from the front end surface of the main body portion toward the front. A bearing is formed in the housing of the lower body to rotatably support the shaft portion of the measuring box that is recessed downward by being inserted from above. A cam disk is provided on the front end surface of the shaft portion, and the cam disk and the operating member are engaged at a position radially separated from the center of the shaft portion.

In the weighing rice bin configured in this way, the shaft portion does not penetrate inside the main body portion of the measuring box, and the rice can be smoothly introduced into the main body portion. Further, by pulling out the shaft portion of the measuring box upward from the bearing of the housing, only the measuring box can be easily taken out from other parts.

However, the measuring rice box of Patent Document 2 has a problem that the measuring box cannot be rotated stably and the operability is not good.

Specifically, in this measuring rice box, as described above, the operating member is engaged with a portion (cam disk) located in the measuring box forward away from the main body portion. Therefore, a large force is applied to the front side portion of the measuring box, and a sufficient force is not applied to the rear side portion. That is, the force applied to the operating member is not evenly applied to the measuring box in the direction of its rotation axis. Therefore, the measuring box is tilted, and the central axis of the shaft portion of the measuring box and the proper rotation axis of the measuring box (rotation axis defined by the mechanism supporting the measuring box) are deviated, and the measuring box rotates stably. It becomes difficult to do.

An object of the present invention is to provide a weighed rice bin that can be easily decomposed and can improve operability while weighing rice more appropriately.

In order to solve the above problems, the present invention is a metered rice bin, which has a storage chamber for storing rice and a drop port for allowing rice to fall in the storage chamber, and the drop port. A housing having a drop port for dropping the rice dropped from the drop port, a weighing member capable of weighing the rice dropped from the drop port and deriving it to the dropping port, and an operating member for operating the measuring member. The measuring member is provided with an operating member having an operating force transmitting portion that is displaced in the vertical direction when the operating force is received by the operator, and the measuring member is an introduction port into which rice dropped from the falling port is introduced. A pair of side walls that define a storage chamber for accommodating a certain amount of rice between the tubular peripheral wall on which the rice is formed, and a pair of side walls provided on each of the side walls along the axial direction of the peripheral wall. A pair of shaft portions extending in a direction away from the peripheral wall and a member to be operated that are detachably engaged with the operating force transmitting portion are provided in the housing, in which the introduction port faces the drop port. The shaft of the measuring member in a state in which the measuring member can be rotated around the axis of the peripheral wall between the position and the outlet position where the introduction port faces the dropping port and the measuring member is detachable from the housing. The operated member is rotatably provided on the peripheral wall of the measuring member so as to support the portion, and the measuring member moves around the axis of the peripheral wall as the operating force transmitting portion is displaced in the vertical direction. The members to be operated extend from the peripheral wall of the measuring member to the outside in the radial direction of the peripheral wall, and the pair of the members to be operated are opposed to each other in the circumferential direction of the peripheral wall. Provided , the operating force transmitting portion is provided with a measuring rice bin , which is inserted into the space between the abutting plates from the outside in the radial direction of the peripheral wall .

In this configuration, only the measuring member can be taken out from other parts, and maintenance and cleaning of the measuring member and its surroundings can be easily performed.

Moreover, the shaft portion of the measuring member extends in the direction away from the peripheral wall on the side wall that divides the accommodation chamber, and the operated member that transmits the operating force applied to the operating member partitions the accommodation chamber among the measuring members. It is rotatably provided integrally with the peripheral wall located between the side walls. Therefore, compared to the case where the shaft portion is provided inside the storage chamber, the rice is introduced into the storage chamber more smoothly and uniformly, and the rice is weighed more appropriately in the axial direction with respect to the measuring member. The operating force can be applied more uniformly, and the measuring member can be rotated stably. In particular, the weight of the peripheral wall portion becomes heavier than that of other portions due to the introduction of rice into the containment chamber. Therefore, by applying the operating force directly from the operating force transmitting unit to the operated member provided on the peripheral wall having a large weight, the measuring member can be rotated more stably.

Therefore, according to this configuration, it is possible to improve the maintainability and the operability while realizing more appropriate weighing of rice.

Further comprising a pair of contact plates facing each other in the circumferential direction of the peripheral wall, said operating force transmitting unit, that is inserted from the outer side in the radial direction of the peripheral wall into the space of the abutment plates.

According to this configuration, the operating force transmitting unit can be detachably connected to the operated member with a simple configuration. Moreover, the operating force transmitting portion can be brought into contact with the operated member from both sides in the circumferential direction of the peripheral wall. Therefore, the operating force transmitting unit can more reliably move the operated member in the circumferential direction of the peripheral wall, that is, rotate it.

The front side of the paper will be described as the left side.

The weighing rice bin 1 includes a storage body 110 in which a storage chamber 11 for storing rice is formed inside, and a lower body 120 for measuring and taking out rice. The lower body 120 is detachably connected to the reservoir 110 below the reservoir 110.

(1) Reservoir FIG. 3 is a schematic exploded perspective view of the reservoir 110.

The storage body 110 includes a storage body main body 20, a reinforcing plate (reinforcing wall) 30 attached to the storage body main body 20 so as to close the opening 20a above the storage body main body 20, and an opening 30a formed in the reinforcing plate 30. It has a lid portion 40 for opening and closing. These are formed separately from each other.

As shown in FIG. 3, the storage body main body 20 includes a side wall (outer wall) 21 that surrounds the storage chamber 11, an opening 20a that opens the storage chamber 11 upward, and a bottom wall that constitutes the bottom surface of the storage chamber 11. It has 25 and.

The bottom wall 25 is formed with a drop port 25a that penetrates the bottom wall 25 up and down to allow rice in the storage chamber 11 to fall downward.

The side wall 21 surrounds the storage chamber 11. The side wall 21 includes a front side wall 21a, a rear side wall 21b, a right side wall 21c, and a left side wall 21d, which extend in the vertical direction and form a front surface, a rear surface, a right surface, and a left surface of the weighing rice box 1, respectively. Each of the side walls 21a to 21d is a plate-shaped member, and a portion surrounded by the upper edges of the side walls 21a to 21d forms the opening 20a.

The bottom wall 25 is inclined downward from the inner side surfaces of the side walls 21a to 21d toward the drop port 25a.

The outer surfaces of the side walls 21a to 21d constituting the front surface, the rear surface, the right surface, and the left surface of the weighing rice bin 1 are substantially flat except for the portion connecting them.

Locking projections 22 that project horizontally toward the inside of the storage chamber 11 are formed at the upper ends of the side walls 21a to 21d, respectively. Further, at the upper ends of the side walls 21a to 21d, a plurality of ribs 23 are formed so as to project toward the inside of the storage chamber 11 to increase the rigidity of the storage body main body 20.

The front side wall 21a is formed with an opening 21e into which a transparent panel 29 (see FIG. 2) for checking the inside of the storage chamber 11 is fitted.

The reinforcing plate 30 is a member for increasing the rigidity of the reservoir 110 and suppressing its deformation. Specifically, as described above, the side walls 21a to 21d of the reservoir body 20 have a plate shape extending in the vertical direction, and their upper edges are opened so as to partition the opening 20a. Therefore, when a large amount of rice is put into the storage chamber 11 and a force in the outer peripheral direction is applied to these side walls 21a to 21d (in a state where the reinforcing plate 30 is not attached), the vicinity of the upper ends of the side walls 21a to 21d becomes. It may be easily deformed in the horizontal direction. On the other hand, if the reinforcing plate 30 is locked to the upper ends of the side walls 21a to 21d, the reinforcing plate 30 regulates the horizontal deformation and displacement of the side walls 21a to 21d. That is, in the state where the reinforcing plate 30 is attached, in order for the vicinity of the upper end of each side wall 21a to 21d to be deformed in the horizontal direction, it is necessary to deform the reinforcing plate 30 extending in the horizontal direction, so that each side wall 21a to 21d The vicinity of the upper end of is not easily deformed or displaced. Therefore, the deformation of the reservoir 110 is suppressed by attaching the reinforcing plate 30 to the reservoir body 20. In particular, in the present embodiment, since the reinforcing plate 30 is provided with the leg portion 32 protruding downward to increase the rigidity of the reinforcing plate 30 itself, the rigidity of the reservoir 110 can be further increased.

Then, in this state, each operating force transmitting portion 75 is inserted into the groove 63d of each operated projection 63 of the drum 60 from the radial outer open end of the groove 63d. As a result, the operating lever 70 and the drum 60 are engaged with each other.

After engaging the operation lever 70 with the drum 60, the drum 60 is moved downward while operating the operation reception unit 78 of the operation lever 70 upward. As a result, the drum 60 is mounted on the housing body 50 in a state of being engaged with the operation lever 70.

<Cover>
FIG. 21 is a plan view of the cover 80. FIG. 22 is a sectional view taken along line XXII-XXII of FIG. In the following description of the cover 80, the front-back, left-right, and up-down directions when the cover 80 is attached to the housing body 50 will be simply referred to as front-back, left-right, and up-down directions.

The cover 80 is a member that covers the drum 60 from above. The cover 80 has a box side covering 81 that covers the box 61 of the drum 60 from above, and shaft side coverings 82 and 82 that cover each drum support shaft 62 of the drum 60 from above.

Specifically, the box side covering portion 81 extends in the left-right direction and has a substantially semicircular cross section, and covers the upper half portion of the box portion 61 from above. Further, the shaft-side covering portions 82 and 82 project outward in the left-right direction from the left and right side walls 81a and 81a of the box-side covering portion 81. The shaft-side covering portions 82 and 82 also have a substantially semicircular cross section, and cover the upper half portion of the drum support shaft 62 from above.

A substantially rectangular opening 83 extending to the left and right is formed on the upper surface of the box side covering portion 81.

Plate-shaped locking plates 84 extending in the vertical direction are provided in the vicinity of both ends of the cover 80 in the front-rear direction in the left-right direction. Specifically, the brim portion 85 extends in the horizontal direction from both the front-rear edges of the box-side covering portion 81 and the shaft-side covering portion 82, and the locking plate 84 extends upward from the brim portion 85. Is extended. The locking plate 84 is formed with a locking projection 84a projecting outward in the front-rear direction at a substantially central portion above and below the locking plate 84.

As shown in FIG. 12 and the like, the cover 80 is inserted into the first recess 210 from above the drum 60, and the locking projections 84a are inside the locking holes 215a formed in the first recess 210 of the housing body 50. By being inserted into and engaging with the drum 60, the drum 60 is fixed to the housing body 50 while covering it from above. As a result, the movement of the drum 60 upward is restricted. At this time, the locking projection 84a is easily inserted into the locking hole 215a by elastically deforming the locking plate 84 in the front-rear direction.

The opening 83 of the cover 80 is fixed to the housing body 50 with the drop port 25a housed inside, and guides the rice that has fallen from the drop port 25a into the box 61.

In the present embodiment, the foamed polyethylene 320 is attached to the lower surface (inner peripheral surface) of the box side covering portion 81 located at the rear edge portion of the opening 83. Specifically, the foamed polyethylene 320 is provided between the vicinity of the trailing edge of the opening 83 and the portion behind the cover 80 of the cover 80. In this embodiment, as shown in FIG. 12 and the like, it is a part of the outer peripheral surface of the peripheral wall 61a of the drum 60, and is on the lower side in a state where the introduction port 61d and the drop port 25a of the drum 60 communicate with each other. Foamed polyethylene 321 is also attached to the outer peripheral surface of the portion.

(3) Operation In the weighing rice box 1 configured as described above, as shown in FIG. 12, the introduction port 61d and the drop port of the drum 60 are placed in a state where the operation reception unit 78 of the operation lever 70 is arranged at the introduction position. The 25a and the 25a communicate with each other through the opening 83 of the cover 80. Along with this, the rice in the storage chamber 11 falls into the drum 60 through these openings 61d, 25a, 83, and a predetermined amount of rice is stored in the drum 60. On the other hand, the entire drop port 212 is blocked by the peripheral wall 61a, and the fall of rice through the drop port 212 is restricted.

At this time, as shown in FIG. 12, the holding contact piece 77 of the operation lever 70 is below the holding protrusion 257 of the housing body 50, and the holding protrusion 257 contacts the holding contact piece 77 from above. It is arranged at a possible position, and this contact restricts the movement of the operating lever 70 to the lead-out position side.

From this state, when the operation receiving unit 78 is pressed downward, the operation lever 70 rotates. However, as described above, the movement of the operating lever 70 to the lead-out position side is restricted by the contact between the holding protrusion 257 and the holding contact piece 77, and only when a force for releasing this contact is applied. The operating lever 70 rotates. Specifically, when a predetermined force or more is applied, the holding contact piece 77 gets over the holding protrusion 257 and moves upward, and the operating lever 70 rotates.

Then, when the operating lever 70 rotates, as shown in FIG. 13, the operating force transmitting unit 75 swings upward, and accordingly, the operated protrusion of the drum 60 engaged with the operating force transmitting unit 75. 63 moves upwards. Specifically, the operating force transmitting unit 75 abuts on the contact wall 63a on the upper side of the operated projection 63 from below, so that the operated projection 63 is pushed upward. Specifically, at this time, the operating force transmitting unit 75 moves upward while sliding in the groove 63d of the operated projection 63 in the radial direction outward of the peripheral wall 61a.

As a result, the protrusion 63 to be operated and the drum 60 oscillate around the axis of the peripheral wall 61a of the drum 60, and the peripheral wall 61a closes the opening 83 of the cover 80. When the operation receiving unit 78 moves to the lower lead-out position, the peripheral wall 61a closes the entire opening 83 and the drop opening 25a of the cover 80, and rice falls from the opening 83 and the drop opening 25a into the drum 60. Be regulated. On the other hand, the introduction port 61d of the peripheral wall 61a and the drop port 212 come into communication with each other, and the rice in the drum 60 falls from the drop port 212. The fallen rice is stored in the tray 90. In this way, a certain amount of rice is dropped into the tray 90.

Here, while the operation receiving portion 78 is moving to the lead-out position, the lower end portion of the operation lever 70 presses the holding locking piece 254 downward, and the upper end (bulging) of the bulging portion 254a of the holding locking piece 254. It moves backward over the uppermost bulging portion of the protruding portion 254a). Therefore, when the operation receiving portion 78 moves to the lead-out position and the lower end portion of the operation lever 70 moves to the rear of the upper end portion of the bulging portion 254a, the holding locking piece 254 elastically returns to the bulging portion 254a. There consisting rear to the lower end of the operation lever 70 into abutment. As a result, the forward movement of the lower end portion of the operating lever 70, that is, the upward rotation of the operation receiving portion 78 is restricted, and the return of the operating lever 70 to the introduction position side is restricted.

Further, FIG. 14, as described above with reference to FIG. 15, when the operating lever 70 is moved to the derived position from the introduction position, the drawer stopper 310 is moved downward, the notch within 311a of drawer stopper 310, The upper end of the pull-out prevention wall 95 is inserted. Then, the movement of the tray 90 in the front-rear direction is restricted.

On the other hand, when the operation receiving unit 78 is pressed upward after the rice is dropped on the tray 90 or the like, the operating force transmitting unit 75 swings downward to the contact wall 63a below the operated projection 63. By abutting from above, the operated protrusion 63 is pushed down. As a result, the drum 60 rotates in the direction in which the peripheral wall 61a closes the drop port 212, and returns to the state shown in FIG. At this time, the operating lever 70 rotates while pressing the bulging portion 254a downward.

Further, the drawer stopper 310 moves upward to allow the tray 90 to move in the front-rear direction. Further, as described above, as the operation lever 70 is rotated to the introduction position, the holding contact piece 77 gets over the holding protrusion 257 and is arranged below the holding protrusion 257, and the contact causes the operation lever 70 to move. The rotation is restricted.

(4) Action, etc. As described above, in the measuring rice box 1 of the present embodiment, the reservoir 110 and the lower body 120 can be easily decomposed. Further, the drum 60 can be easily removed from the housing body 50 by pulling it upward, and the drum 60 can be easily attached to the housing body 50 from above. Therefore, cleaning of the drum 60 and maintenance around the drum 60 can be easily performed.

Further, the drum support shafts 62 and 62 of the drum 60 extend from the left and right side walls 61b and 61b of the box 61 to the left and right outside, and the shaft does not penetrate inside the box 61. Therefore, the rice can be smoothly dropped into the box 61. In addition, rice can be introduced more evenly into the box 61, and rice can be weighed more appropriately.

Here, in order to allow the drum 60 to be rotatably supported by the housing body 50 and the drum 60 to be easily attached to and detached from the housing body 50, the connection between the housing body 50 and the drum 60 is not strong. Is preferable. However, in this case, the drum 60 becomes stable and difficult to rotate. In particular, as described above, in the present embodiment, the drum 60 can be attached to the housing body 50 simply by inserting the drum 60 into the first recess 210 from above, and the drum 60 can be attached and detached very easily. Can be done. However, since the upper half of the rotation shaft of the drum 60 is not supported, the rotation of the drum 60 tends to be unstable.

On the other hand, in the present embodiment, the peripheral wall 61a of the drum 60 is provided with the operated protrusions 63, 63 protruding outward in the radial direction, and the operated protrusions 63, 63 and the operating lever 70 (operating force transmitting unit) are provided. 75) is designed to engage. That is, an operating force is applied to the peripheral wall 61a of the drum 60 via the operating lever 70. Therefore, the force can be applied to the drum 60 more evenly in the axial direction, and the drum 60 can be rotated stably. In particular, the weight of the peripheral wall 61a portion of the drum 60 becomes larger than that of the other portion due to the introduction of rice into the storage chamber 61c surrounded by the peripheral wall 61a. Therefore, the drum 60 can be stably rotated by directly applying the operating force to the heavy peripheral wall 61a.

Further, in the present embodiment, the operated protrusion 63 has a pair of contact walls 63a, 63a arranged in the circumferential direction of the peripheral wall 61a of the drum 60, and the operating force transmitting portion 75 is inside the contact walls 63a, 63a. Is inserted so that the operated protrusion 63 and the operating force transmitting portion 75 are engaged with each other. Then, when the operating force transmitting unit 75 is displaced (rotated) in the vertical direction, the operating force transmitting unit 75 comes into contact with the contact wall 63a and presses the contact wall 63a in any direction. There is. Therefore, the operating force applied to the operating lever 70 can be more reliably transmitted to the operated projection 63 and the drum 60, and the operability is improved.

Further, the groove 63d formed between the contact walls 63a and 63a opens outward in the radial direction of the peripheral wall 61a of the drum 60, and as described above, the groove 63d can be easily inserted into the contact walls 63a and 63a from this open end. The operating force transmitting unit 75 can be inserted and pulled out from the contact walls 63a and 63a. Therefore, as described above, while the operating force can be appropriately applied to the drum 60, the drum 60 can be easily attached and detached to enhance convenience.

Further, in the present embodiment, two operated protrusions 63 are provided, and the operated protrusions 63 are orthogonal to the axis of the peripheral wall 61a of the box portion 61 and pass through the center of the peripheral wall 61a in the axial direction as a reference. , Are provided at positions symmetrical with each other. That is, these operated protrusions 63 are provided at positions symmetrical with respect to the axial center line of the peripheral wall 61a. Therefore, the operating force can be more reliably applied to the drum 60 in the axial direction.

Further, in the present embodiment, the operating lever 70 is supported so as to rotate about an axis extending parallel to the rotation axis of the drum 60. Therefore, with a simple configuration, the operation lever 70 can be stably supported in a state where the operation reception unit 78 and the operation force transmission unit 75 can be displaced in the vertical direction. Specifically, for example, the operating lever 70 can be supported on the housing body 50 so as to be slidably displaced in the vertical direction, but in this case, the structure becomes complicated. Further, in this case, if the force applied to the operating lever 70 is non-uniform in the direction parallel to the rotation axis of the drum 60, the force applied to the drum 60 tends to be non-uniform as it is. On the other hand, in the present embodiment, even if the force applied to the operating lever 70 is non-uniform in the direction parallel to the rotation axis of the drum 60, the movements of both operating force transmitting units 75 are maintained the same. Therefore, the drum 60 can be operated more uniformly in the direction parallel to its rotation axis.

Further, in the present embodiment, the operation receiving unit 78 of the operating lever 70 and the operating force transmitting unit 75 extend in the front-rear direction, that is, the side wall 73 extending in the direction orthogonal to the axis of the peripheral wall 61a of the drum 60, that is, the rotation axis of the drum 60. The operation lever 70 is provided at both ends of the above, and the operation lever 70 rotates about an axis passing through a position between the operation reception unit 78 and the operation force transmission unit 75 in the front-rear direction.

Therefore, the force applied to the operation reception unit 78 can be more appropriately transmitted to the operation force transmission unit 75 and the drum 60. Specifically, for example, when the operating lever 70 and the operating force transmitting unit 75 are connected via a link mechanism or the like, the structure becomes complicated. Further, for example, when the operation lever 70 is bent between the operation reception unit 78 and the operation force transmission unit 75, the distribution of the force applied to the operation lever 70 in the axial direction of the drum 60 may be biased. There is. On the other hand, in this embodiment, the force applied to the operation receiving unit 78 can be transmitted to the drum 60 more uniformly in the axial direction of the drum 60 with a simple configuration.

Further, in the present embodiment, the holding locking piece 254, more specifically, the bulging portion 254a of the holding locking piece 254 regulates the operation lever 70 from rotating from the lead-out position to the introduction position side. .. Therefore, when the rice is led out to the tray 90, it is not necessary to keep pressing the operation receiving unit 78 so that the operating lever 70 is maintained at the drawn-out position, which enhances convenience.

In particular, in the present embodiment, the movement of the operating lever 70 is restricted by using the holding locking piece 254 that elastically displaces in the vertical direction, and this regulation can be realized with a simple configuration, and the operating lever 70 can be realized. Can be easily operated to the introduction position side.

Further, in the present embodiment, when the operating lever 70 is in the lead-out position, the drawer stopper 310 restricts the tray 90 from being pulled out forward. Therefore, when the rice is led out to the tray 90, the tray 90 can be pulled out forward to prevent the rice from being scattered on the floor or the like other than the tray 90, and the convenience is enhanced.

Further, in the present embodiment, the upper half of the drum 60 inserted into the first recess 210 is covered with the cover 80. Further, the cover 80 is locked to the housing body 50 while covering the drum 60. Therefore, as described above, it is possible to suppress the rattling of the drum 60 while facilitating the attachment / detachment of the drum 60 by housing the lower half of the drum 60 in the first recess 210. In particular, in the present embodiment, the locking holes 215a for locking the cover 80 are provided at positions symmetrical with respect to the center in the left-right direction of the box accommodating portion 211 accommodating the box portion 61. Therefore, the displacement of the box 61 can be regulated more evenly in the axial direction by the cover 80, and the drum 60 can be rotated stably.

Further, in the present embodiment, the storage body 110 is composed of a storage body main body 20 and a reinforcing plate 30 which are separate from each other, and the reinforcing plate 30 is engaged with the opening 20a of the storage body main body 20. There is. Therefore, the deformation of the reservoir 110 can be suppressed.

Specifically, as described above, in the present embodiment, the storage body 110 and the lower body 120 are detachably connected to each other, and it is difficult to secure the rigidity of the storage body 110. Therefore, when a large amount of rice is introduced into the storage chamber 11, the side wall 21 of the storage body 110 may be deformed due to the weight thereof. On the other hand, in this embodiment, the reinforcing plate 30 is engaged with the opening 20a surrounded by the upper edge of the side wall 21 of the reservoir body 20, so that the deformation of the side wall 21 is regulated by the reinforcing plate 30. To. Therefore, the deformation of the side wall 21 and thus the reservoir 110 can be suppressed.

Moreover, in the present embodiment, while the storage body main body 20 and the reinforcing plate 30 are separated in this way, their outer peripheral surfaces are flatly continuous vertically, and the storage body main body 20 and thus the weighing rice bin 1 Can improve the appearance of.

Further, in the present embodiment, an opening 30a is formed in the reinforcing plate 30, a lid portion 40 for opening and closing the opening 30a is provided, and a packing 300 is sandwiched between the lid portion 40 and the reinforcing plate 30. ing. Therefore, it is possible to easily introduce rice into the storage chamber 11 through the opening 30a, and it is possible to suppress water from entering the storage chamber 11 through the opening 30a.

(5) Modification Example In the above embodiment, the case where the drum 60 is arranged so as to extend in the left-right direction, that is, in the width direction (short direction) of the weighing rice bin 1, but the central axis of the drum 60 is the weighing rice bin. The drum 60 may be arranged so as to extend along the longitudinal direction of 1.

The specific shape of the operating lever 70 and the support structure thereof are not limited to the above. For example, the operating lever 70 may be supported so as to be slidably movable in the vertical direction.

In the above embodiment, the case where the lower half of the box 61 of the drum 60 and the lower half of the drum support shafts 62 and 62 are inserted into the box housing 211 and the drum bearing 214, respectively, has been described. And the portion accommodated in the drum bearing 214 is not limited to this.

Further, the number and arrangement of the locking holes 215a formed in the vertical wall 215 of the housing body 50 are not limited to the above. The holding locking piece (operating member regulating portion) 254 and the stopper 310 can be omitted.
