Description

  The present invention relates to a stone milling machine for grain such as brown rice.

The brown rice may be mixed with foreign substances such as stones. Therefore, when performing the rice polishing, after removing the foreign matter by putting the unpolished rice into a stone remover, the rice is supplied to the rice milling tank of the rice milling machine (elevator) to perform the rice polishing (see, for example, Patent Document 1). ).
Note that instead of an elevator, a threshing thrower may be used as the cerealing machine, and this slaughter is connected to a cerealing chamber in which whipping blades are built in and to the upper end of the cerealing chamber. And a slotter drive motor that is linked to a destoner motor.

  Also, in a stone-removing rice mill that does not use a pulverizer, a stone-removing machine is installed below the rice-milling exit of the rice-milling machine, and after brown rice is polished by the rice-milling machine, it is dropped on the perforated plate of the stone-removing machine. The stone is removed (for example, refer to Patent Document 2).

Japanese Patent No. 3182712 Japanese Patent No. 30699904

The conventional example has the following problems.
(1) When using a cerealing blower, when the motor of the stone remover is turned off (off), the operation of the stone remover is stopped and the operation of the blower is also stopped. Kernels remain in the cereal chamber. Therefore, when the cereal thrower is started next time, it receives a load of the residual cereal and the supply of the cereal from the destoner starts, so that it is difficult to scrape the cereal in the cereal chamber. . As a result, the throttle may eventually become clogged and may not be discharged.

(2) Since the stone remover is relatively large and fixed to the side of the rice milling machine, it is difficult to remove this stone remover and carry it to a place where it is easy to perform maintenance work. It is.
(3) A predetermined gap is required between the outer peripheral end of the cerealing blade and the bottom wall of the cerealing chamber. If this gap is made too wide, it will not be possible to scrape the grains located in the gap, and conversely if the gap is made too narrow, the tip of the cereal blade will contact the bottom wall of the cereal chamber. And may be damaged. As described above, the size of the gap is extremely important, but adjusting as designed requires a technique and is a difficult task.

  (4) In the stone remover, the cerealing chamber and the slot cylinder are non-rotatably connected. For this reason, it is inconvenient because the outlet of the slot can not be directed to the rice mill or to the brown rice bag near the rice mill.

  In view of the above circumstances, the present invention is to prevent clogging of a threshing thrower and to easily adjust a gap between a cerealing blade and a cerealing chamber bottom wall. Another object is to reduce the size of the stone removing machine and facilitate maintenance.

This invention is a stone removing machine part that removes foreign matters mixed in the grain, a rice milling machine part that refines the grain, and a grain supplied to the cerealing room from the stone removing machine part, In a stone-milled rice mill provided with a grain- milling rice mill that cereals the rice-milling machine part by means of a grain-milling blade; And delay control means for discharging the residual grain.

The delay control means according to the present invention is a microcomputer program that causes the thrower motor to be extended for a predetermined time when the main power switch is turned off. Delay control means of the invention, a sensor for detecting the residual grains of the AgeKoku chamber, a delay control circuit for a shutdown of the Surowamota Ru delays for the output of the sensor of the AgeKoku Surowa comprises It is characterized by that. The sensor according to the present invention is a transmissive optical sensor or a contact sensor provided in a slot cylinder continuous with the cerealing room.

  A thrower cylinder is rotatably connected to the cerealing room of the present invention. A gap adjusting member extending toward the bottom wall of the cerealing chamber is provided at the tip of the cerealing blade of the present invention. The gap adjusting member according to the present invention is a brush or a spatula elastic plate.

The present invention is characterized in that a stone removing machine part and a rice milling machine part are provided side by side on a base, and the stone removing machine of the stone removing machine part is stored in a stone removing machine storage part so as to be able to be taken in and out. . The destoning machine storage portion of the present invention is provided with a guide that also serves as a dust-preventing wall that is generated during destoning work, guides the loading and unloading of the destoning machine, and a stopper that fixes the destoning machine.

According to the present invention, a stone removing tank is provided at an upper portion of the perforated plate of the present invention, and an elastic relay cylinder is provided at an outlet of the stone removing tank.

  In the present invention, since the cereal thrower is provided with a delayed operation control means for discharging the residual cereal, the cereal thrower continues to operate even after the operation of the stone remover is stopped, After draining the residual grain in the room, the operation is stopped. Therefore, unlike the conventional example, the whipping blades rotate smoothly at the time of starting the whipped slaughter, and the occurrence of the clogging phenomenon can be prevented.

  In the present invention, since the slot is connected to the cerealing chamber so as to be rotatable, the position of the discharge port can be changed by rotating the slot. Therefore, it is possible to supply the deceased grain not only to the rice milling machine part but also to other places such as a container such as a brown rice bag.

  In this invention, since the clearance adjustment member extending toward the bottom wall of the cerealing chamber is provided at the tip of the cerealing blade, the clearance between them can be easily adjusted. That is, since the gap can be easily adjusted by adjusting the tip position of the cereal blade, even if the outer diameter of the cereal blade is smaller than the design value, it can be adjusted by the gap adjustment member, The outside dimension of the whipping blade may be rough.

Next, the operation of the present embodiment will be described.
Operation of stone-free rice milling machine:
After putting grain, for example, mixed stone brown rice ks, into the stone removal tank 12, a main power switch (main switch) (not shown) is turned on (ON). Then, the rice milling motor, the stone drilling machine motor 40, and the thrower motor 68 are started, and the milling roll, the fan 20, the cam 38, and the cerealing blade 54 rotate, and the perforated plate 18 slides in the direction of arrow A18.

  When the opening / closing lever of the stone removal tank 12 is pulled by hand to open the shutter, the mixed stone brown rice ks falls onto the perforated plate 18. The mixed stone unpolished rice ks flows down while receiving the sorting air A20 from the fan 20, and flows into the cerealing chamber 28 through the slot hopper 52 and the slot supply port 53. The stone s moves upward by the sliding of the perforated plate 18 and is collected in the vicinity of the stone discharge port 22.

  The brown rice k in the cerealing chamber 28 is scraped up by the cerealing blades 54 and rises in the slot 56, and falls into the milled rice tank 7 from the discharge port 56a.

The brown rice k in the milled rice tank 7 falls into a milling chamber (not shown) and is milled, becomes white rice w and is discharged from the milled rice outlet 10 into a milled rice container (not shown).
In the case where only stone removal is performed, as shown by a chain line in FIG. 2, the lower cylinder 56 is rotated so that the discharge port 56 a faces the upper portion of the bag 78 from the milled rice tank 7 and the brown rice k is placed in the bag 78. Drop it.

Decommissioning of stone-free rice milling machine:
When the main switch is turned off (off), the rice milling motor and the stone removing motor 40 are stopped, but the throttle motor 68 is not stopped.

The residual grain detection sensor 60 detects the residual grain k in the lifting chamber 28, and while the residual grain k exists, the light of the light emitting element 60a of the sensor 60 is the residual grain. Since it is blocked by k, it does not enter the light receiving element 60b.
Thereafter, when the residual grain k is lifted up by the whipping blade 54 and disappears, the light of the light emitting element 60a of the sensor 60 enters the light receiving element 60b, and the light receiving element 60b outputs a detection signal to the delay circuit 62. .

  Then, the delay circuit 62 turns off the switching circuit 66 after a certain time, for example, 3 seconds, and stops the thrower motor 68. Therefore, the thrower motor 68 stops in the state where the residual grain k does not exist in the whipping chamber 28.

  When the stone outlet lever 24 is operated to open the stone outlet 22, the stone s is discharged outside the vessel.

Destoner maintenance:
As shown in FIGS. 5 and 6, the door fixing screw 46 is turned with a screwdriver 80 to remove the stone removal inspection door 44. Then, after removing the stopper (fixing screw) 50 and releasing the fixation between the stone remover 14 and the base 1, as shown in FIG. 7, when a hand H is put on the handle 82 and the stone remover 14 is pulled forward. The stone removing machine 14 is pulled out of the machine while being guided by the guide rail 48.

The deburring machine 14 is carried to a place where it is easy to work, and maintenance such as cleaning of the perforated plate 18 is performed.
After the maintenance work is completed, the stone remover 14 is returned to the storage portion 13 in the reverse manner as described above, and after the stopper 50 is applied, the stone removal inspection work door 44 is closed and fixed with the fixing screw 46.

A second embodiment of the present invention will be described with reference to FIG. 12. The same reference numerals as those in the drawings have the same names and functions.
The difference between this embodiment and the first embodiment is as follows.
(1) The threshing blade 90 is a U-shaped blade composed of a rectangular front wall 90a and side walls 90b erected on both side edges of the front wall 90a.
(2) A spatula-like elastic plate 92 is provided at the tip of the front wall 90a. The spatula-like elastic plate 92 is made of, for example, rubber, and a tip 92a thereof is close to or slightly in contact with the inner peripheral surface of the bottom wall 28a of the whipping chamber.

A third embodiment of the present invention will be described with reference to FIG. 13. The same reference numerals as those in the drawings have the same names and functions.
The difference between this embodiment and the first embodiment is that when the main power switch (main switch) 96 is turned off, the microcomputer program 98 is activated, and the thrower motor 68 is stopped after a certain period of time, for example, 1 minute. It is that. This delay time is appropriately set in consideration of the time required for discharging the residual grain. Reference numeral 100 denotes a power plug.

Embodiment 4 of the present invention will be described with reference to FIG. 14. The same reference numerals as those in the drawings have the same names and functions.
The difference between this embodiment and the first embodiment is the arrangement position of the residual grain detection sensor. Since this residual grain detection sensor should just be provided in the place where residual grain accumulates, or the place which passes, it can also be arrange | positioned as follows.
(1) As shown in FIG. 14 (A), a transmission type optical sensor comprising a light emitting element 60a and a light receiving element 60b is disposed on the lower bottom wall 28a of the whipping chamber 28.

(2) As shown in FIG. 14B, a transmissive optical sensor comprising a light emitting element 60a and a light receiving element 60b is disposed in the slot cylinder 56.
(3) As shown in FIG. 14 (C), a contact type grain detection sensor 61 is provided on the slot cylinder 56.

A fifth embodiment of the present invention will be described with reference to FIGS. 15 to 17. The same reference numerals as those in the drawings have the same names and functions.
As a result of the experiment, the inventor of the present invention supplies not only the opening degree (opening area) of the shutter but also the porous plate 18 to supply a certain amount of mixed stone unpolished rice ks from the stone removal tank 12 onto the selected porous plate 18. I learned that the distance to the exit of the stone removal tank 12 is also related. Therefore, by connecting the relay cylinder 102 to the outlet, the position of the outlet is adjusted, and the relay cylinder is formed of an elastic member that can be easily deformed and restored so as not to obstruct the removal and insertion of the stone remover. It was decided.

The difference between this embodiment and the first embodiment is that an elastic relay cylinder 102 is continuously provided at the outlet 12 a of the stone removal tank 12.
The cross-sectional shape of the relay cylinder 102 is formed in a rectangular shape according to the outlet 12a. However, it is not always necessary to match the outlet 12a. Since the relay cylinder 102 is located in the movement locus when the stone remover 14 is taken in and out of the storage portion 13, it is deformed when pressed by the stone remover and the pressing force is released. In order to be able to return to the original state when it is done, it is made of an elastic member, for example, rubber, synthetic resin or the like.

  A flange portion 102 a is provided at the upper end portion of the relay cylinder 102, and this flange portion 102 a is fixed to the lower surface of the stone removal tank 12 by a metal stopper 104. The upper end of the relay cylinder 102 constitutes a support portion for a metal shutter plate 106 that slides along the lower surface of the stone removal tank 12. Therefore, the shutter plate 106 receives the frictional resistance at the upper end, so that the relay cylinder 102 also functions as a stopper (anti-slip) for the shutter ST.

  The shutter plate 106 includes a rectangular portion 106a, a vertical portion 106b, and a positioning slot 106c. An opening / closing lever 108 for sliding the shutter plate 106 is connected to the vertical portion 106b. A leg 110a of a positioning screw 110 provided in the stone removal tank 12 is loosely fitted in the positioning long hole 10c.

The shutter plate 106 includes a rectangular portion 106a, a vertical portion 106b, and a positioning slot 106c. An opening / closing lever 108 for sliding the shutter plate 106 is connected to the vertical portion 106b. The elongated positioning hole 10 6 c, legs 110a of the positioning screw 110 provided on the stone vent tank 12 is loosely fitted.

  If the distance L is too long (the relay cylinder 102 is too short), the amount of mixed stone brown rice Ks that falls onto the perforated plate 18 from the outlet 12a increases, and the mixed stone brown rice ks on the porous plate 18 increases. Is excessively thick and is supplied so as to overflow to the vicinity of the grain outlet 25 without being subjected to sufficient sorting. On the contrary, if the interval L is too short (the relay tube 102 is too long), the stone remover 14 When it is taken in and out of the case body 2, troubles occur and the work in and out cannot be performed smoothly.

In this way, by appropriately designing the length of the relay cylinder 102, the interval L can be optimized, so that the supply amount of the mixed stone unpolished rice ks can be controlled and stabilized.
In the present embodiment, the angle of repose θ when the mixed stone unpolished rice ks drops and accumulates on the perforated plate 18 to form a mountain shape is 35 °.

Next, the operation of this embodiment will be described.
When the opening / closing lever 108 is pulled by hand after driving the stone remover 14 and the shutter ST is opened, the mixed stone brown rice ks passes through the outlet 12a and the relay cylinder 102 and falls onto the swinging perforated plate 18. To do. The fallen mixed stone brown rice ks flows down while being dispersed on the porous plate 18, and the brown rice k descends toward the grain outlet 25 side while the stone s moves on the porous plate 18. Heading towards the stone outlet 22 side while rising. Thereby, the brown rice k and the stone s can be completely separated.

When a mixed stone brown rice sensor (not shown) provided on the inner surface of the stone removal tank 12 is activated, the stone removal machine 14 is automatically stopped, and the swinging of the perforated plate 18 is stopped.
At this time, the mixed stone unpolished rice ks is deposited on the perforated plate 18 and is in a piled state, but since this mountain has an angle of repose θ, it is stable. Therefore, even if vibration is generated by a rice mill during operation, the mountain does not collapse, so the mixed stone unpolished rice ks does not flow down. Therefore, it is possible to prevent the mixed stone unpolished rice ks from flowing down into the grain outlet 25 in an unselected state.
