If Yes, the vibration motor 35 is driven for a predetermined time to vibrate the net body 35 of the input hopper 5. Then, the adhering kernel is dropped (step S1). Next, a rice milling end operation for a predetermined time is started, and the brown rice feeding means 8, the first elevator 11, the stone remover 12, the second elevator 13, the brown rice tank 14, the rice mill 15, and the rice bran discharge fan 16 are sequentially operated (step) S12) When the predetermined time is over, the rice milling operation is stopped (step S13), the door is closed, and the rice milling operation is finished.

  Next, FIG. 5 will be described.

  The charging hopper 5 is provided with a net body 34 for removing foreign matter and a vibration motor 35 for vibrating the net body 34. The top of the charging hopper 5 is a square grain input opening in a plan view, the left and right side plates 5a and 5b are vertical, the rear side plate 5c is vertical, the front side plate 5d is downwardly inclined, and the opening The upper plate 5e that closes the rear side portion constitutes a hopper, and brown rice feeding means 8 is provided at the bottom of the hopper.

  As shown in FIG. 6, the mesh body 34 is arranged with vertical round bars 34b,... In the vertical direction at predetermined intervals on the upper surface of the outer frame body 34a having a rectangular shape in plan view. It is welded and attached. .. Are arranged at predetermined intervals on the lower surface side of the outer frame body 34a and attached in the same manner to form a lattice shape.

  According to the above configuration, however, the vertical gap between the vertical round bars 34b,... And the horizontal round bars 34c,. Prevents tangled brown rice and allows it to fall smoothly. Further, both ends of the vertical round bars 34b,... Are welded and attached to the upper surface of the rectangular outer frame 34a, and both ends of the horizontal round bars 34c,... Are welded to the lower surface of the outer frame 34a. Since it is attached, it is possible to reduce the number of welding points and reduce the cost.

  Further, when attaching the mesh body 34 to the charging hopper 5, as shown in FIG. 5, the rear support piece 34d of the outer frame 34a of the mesh body 34 is inserted and supported in the support portion of the rear side plate 5c of the charging hopper 5, The front support piece 34e of the outer frame body 34a is inserted into the support hole of the bracket 36 of the side plate 5d, and is fastened and supported by mounting bolts 37. And the vibration motor 35 is attached to the intermediate | middle outer side part of the up-down direction of the front side board 5d, and the net | network body 34 is located in the upper vicinity of the vibration motor 35. FIG. In addition, a grain charging sensor 31 that forms a protruding portion 31 a inside the charging hopper is attached to the lower part of the front side plate 5 d, and the grain charging sensor 31 is positioned in the vicinity of the lower part of the vibration motor 35. The input sensor 31 is a capacitance type sensor whose capacitance changes when the brown rice comes into contact.

  According to the above configuration, since the vertical intermediate portion of the inclined front side plate 5d of the feeding hopper 5 is vibrated by the vibration motor 35, the brown rice remaining on the front side plate 5d is surely dropped, and is positioned in the vicinity. Since the net body 34 and the grain input sensor 31 are vibrated by the vibrating motor 35, the brown rice caught on the protruding portion 31a of the grain input sensor 31 is surely dropped and fed to the brown rice feeding means 8 with certainty. It is possible to eliminate brown rice from remaining in the grain input sensor 31 and improve detection accuracy.

  Moreover, you may comprise as FIG.

  A net body 34 is attached to the charging hopper 5, and a vibration 35 is attached so as to be positioned on the side of the first elevator 11 on the upper left and right sides of the rear plate 5c. According to the said structure, the brown rice adhering to the net | network body 34 can be dropped by driving the vibration motor 35 at the time of the completion | finish of rice milling work. Further, when the opening / closing door (not shown) is opened and the charging hopper 5 is in a state in which the brown rice can be charged, the vibration motor 35 is provided near the operation chamber 2 of the charging hopper 5, and maintenance of the vibration motor 35 can be performed easily. .

  Moreover, you may comprise as shown in FIG. In attaching the mesh body 34 to the charging hopper 5, the mesh body 34 is inclined forward and inclined so that the left and right front and rear side surfaces of the outer frame 34a are in contact with the left and right side plates 5a and 5b, the front side plate 5d, and the rear side plate 5c. If comprised in this way, brown rice will fall on the net | network body 34, flowing down along the front-falling inclination, and the residue of brown rice can be decreased.

  Moreover, you may comprise as shown in FIG. When attaching the mesh body 34 to the charging hopper 5, the mesh body 34 is inclined forward and inclined, and the front and rear side surfaces of the outer frame body 34 a of the mesh body 34 are contacted and supported by the front side plate 5 d and the rear side plate 5 c. Spacing portions 5f and 5f are formed between both sides and the left and right side plates 5a and 5b. If comprised in this way, since it is separated from the right-and-left space | interval parts 5f and 5f of the right and left sides of the net | network 34 from the brown rice feeding means 8 of the bottom part of the injection | throwing-in hopper 5, the cost of the net | network 34 is avoided, avoiding a user's danger. Can be reduced.

  Next, FIG. 10 will be described. The front support part of the mesh body 34 is supported by the middle part of the front side plate 5d of the charging hopper 5 in a vertically rotatable manner, and the rear support part 34d of the mesh body 34 is vertically movable in the long hole of the rear side plate 5c. To support. Then, a return spring 38 and a solenoid 39 are attached to the rear support portion 34d of the mesh body 34 so that the mesh body 34 can be vibrated up and down. Thus, when the net body 34 is cleaned or when the input hopper 5 is detected as having no grain, the solenoid 39 is driven to vibrate the net body 34 and drop the grains of the input hopper 5 and the net body 34.

  Moreover, you may comprise as shown in FIG. A vibration motor 35 is attached to the upper surface of the upper plate 5d of the charging hopper 5 so that the brown rice of the charging hopper 5 and the net 34 is dropped. According to the above configuration, the vibration motor 35 can be attached to the narrow machine room 3 at a position that does not get in the way.

  Moreover, you may comprise as FIG. Front and rear support rods 34f and 34g are provided on both front and rear sides of the outer frame 34a of the net 34 having a quadrangular shape in plan view. The front and rear support rods 34f and 34g are pivotally supported on the front and rear side plates 5d and 5c of the hopper 5 in a reversible manner. . And if the vibration motor 35 is attached to either of the front and rear support bars 34f and 34b, and the net 34 is vibrated in an inverted state, the insect-feeding brown rice connected in a string shape can be easily dropped.

  A net body 34 is detachably attached to the charging hopper 5, and the net body 34 is provided with a net body detection sensor (not shown) that can detect the lifted state. Thus, when the net body detection sensor detects the lifting of the net body 34, each working unit of the automatic rice milling equipment and the vibration motor 35 are stopped, and the machine is stopped by lifting the net body 35 on a monitor display device (not shown). Display to the effect. Further, when the mesh body 35 is returned to the original state, it is displayed that the attachment state of the mesh body 34 is normal after a predetermined time, so that the driving is resumed, and the driving of each working unit and the vibration monitor 35 is resumed. It is safe.

  The present invention can be applied to rice milling equipment for brown rice milling as well as to rice milling equipment dedicated to brown rice.
