Description

[Detailed description of the invention] This invention is inspired by the improvement of circulating rice milling machines.

This type of rice milling machine has traditionally installed a resistor that can be moved in and out of the circulation circuit that communicates with the exit side of the grain feeding roll chamber, and by changing its protruding length, the pressure of brown rice in the milling chamber can be adjusted. However, depending on the degree of drying of the brown rice to be milled and the progress of milling, the pressure inside the milling chamber increases, resulting in an excess or deficiency in the pressure suitable for the brown rice to be milled.

If the pressure is too high, the rice will be broken, and if it is too low, the efficiency of rice milling will be reduced.

The purpose of the present invention is to
To always maintain the pressure of brown rice at an optimum level in a milling chamber so as not to generate broken rice or reduce milling efficiency during milling.

The present invention will be described with reference to the embodiments shown in the accompanying drawings. First, the lower part of the tank of a so-called circulating rice milling machine is connected to the input/output port 2&, 2b of the grain feeding roll chamber 2, and the grain feeding roll 3 is connected to the grain feeding roll chamber 2.
is rotatably provided by a belt 4 and a raw motor 5, and a circulation circuit 7 is provided between the outlet 2a of the grain roll 2 and the tank 1.
A resistor 6 is provided in this circulation circuit 7, which is inserted and removed by the auxiliary motor 9, and a resistor 6 is provided in the circulation circuit 7 to detect the load current of the main motor 5, as shown in Fig. 73. A flow detector 12 is connected to the state motor 9 and a flow detector 12.
This is a rice milling machine that electrically connects the

The grains such as paddy and brown rice in the tank 1 are moved by the rotation of the grain feed roll 3 to the arrows AI, A2, A3, A4, A3, and A in Figure 1.
It is forced to circulate in the direction of 6. At this time, rice is polished by the friction between the grain feeding rolls 3 and the grains, and the resistor 6 provided in the circulation circuit 7 acts as a circulation load for the grains, and the rice polishing force is increased depending on the length of its protrusion t. Change.

This resistor 6 is connected to an auxiliary motor 9 for driving the resistor 6 via a coupling 8 in a casing 11 outside the circulation circuit 7 . The coupling 8 has an inner screw 8a on the auxiliary motor 9 side screwed into an outer screw 8b on the resistor 6 side, and by driving the auxiliary motor 9, the inner screw 8a is rotated, and the stopper lO rotates the inner screw 8a. The resistor 6, whose rotation is stopped, is moved in and out in its length direction.

The aforementioned main motor 5 and auxiliary motor 9 are connected by an electric circuit as shown in Figure 3.

That is, an output current value detector 12 is connected to the main motor 5 to detect the load current and convert it into a voltage value.

Further, a lighting drive circuit 13 is connected to the output current value detector 12, which classifies or encodes the voltage output by the voltage comparator having one or more reference voltages according to its size and outputs the result. It has been Rized.

Connected to the lighting drive circuit 13 is a C light display device 14 that lights one or more lights in response to a signal sent from the circuit 13-P.

Further, the electric display device 14 is connected to a discrimination table f16 which checks the number of lights lit per lighting position, classifies or encodes the load status of the main motor 5 into light load, proper load, high load, etc. and outputs the result.

Furthermore, the front ε lighting drive circuit 13 includes the above-mentioned discriminating device 1.
A changeover switch 15 is connected to change the state to be determined in No. 6, and the changeover switch 15 is set to correspond to the lighting position or lighting condition of the display device 14 and the load status output of the main motor 5, and the changeover switch 15 is connected to If the resistance amount Z is high moisture rice + 7), set it to "weak", for standard rice, set it to "standard j1", or for low moisture rice, set it to "weak".
It is possible to switch to strong J etc. according to the quality of brown rice, and the nameplate 15a of the changeover switch 15 is ↑
This is shown in Figure 4. ξ Between the city record discriminating device 16 and the auxiliary motor 9, the discriminating device 16 receives a signal to move the resistor 6 in and out of the front layer in the longitudinal direction. An auxiliary motor 9 C1) drive circuit w117 is intervened and connected to perform operations such as stopping.

The above-mentioned electric light display device f14 has seven rectangular light emitting diodes 14a to 14f arranged as shown in FIG. "
6"9 It is marked as "7".

The indicator 15a of the selector switch 15 in Fig. 74 indicates the standard position, and the optimum current value of the main motor 5 at that time is 4 light emitting diodes 14a to 4.
14a lights up, after a while after the start of rice milling, the main motor 5's
The current value begins to fall.

At this time, the number 4 diode 14d that had been lit up until now
When the light goes out, the discrimination device 16 detects a signal to rotate the auxiliary motor 9 in the normal direction, activates the auxiliary motor drive circuit 17, rotates the auxiliary motor 9 in the normal direction, and increases the protrusion length t of the resistor 6. C,
Increase the current value of the rice polishing field 7-ta.

As a result, when the recrystallization diode 14 (L) lights up, the discrimination device 16 stops the signal generation of the auxiliary motor 9.

Then, the drive circuit 17 of the auxiliary motor 9 is turned off, the rotation of the auxiliary motor 9 is stopped, and the protruding length of the resistor 6 is warped! ! -The current value of the main motor 5 is stabilized within an appropriate range.

In addition, even in the case where the diodes 14Q and 14 (L) of No. 3 and No. 4 go out, the same operation as when the diode 14a of the four-point chain goes out, and the When the diode lights up, the resistor 6 is stabilized within an appropriate range.

Contrary to the naming case, an overload is applied to the main motor 5, its current value increases, and the diode 14 of S5 and above
When 15 t % 14 f lights up, the discrimination device 16 discovers a signal that causes the auxiliary motor 9 to reverse @, and the auxiliary motor 9 starts reverse rotation due to the current from the auxiliary motor drive circuit 17, and the resistor 6 The protrusion length L decreases, the load on the main motor decreases, and the current value decreases.

As a result, diodes 14e14 of No. 5 and above were lit.
When r and 14f go out, the discriminator 16 stops the reverse rotation signal, the auxiliary motor drive circuit 17 is turned off, the auxiliary motor 9c/) stops rotating, and the protrusion length '2! of the resistor 6! t becomes constant, and the main motor 5v)'Ft flow value stabilizes within an appropriate range.

When the selector switch 15 in Fig. 4 is switched to the weak (static water) position on the left, the 31-wire diodes 14&% from the first diode 14a to the third diode 14o
141)% When 14G lights up, main motor 5 runs out of operation at a constant current value of 1. The average current value at this time is switch 1.
5 is lower than when it is in the standard position, the amount of resistance against grains is lower, and the occurrence of broken rice, etc. can be prevented.

When the selector switch 15 is set to the 0 position (low moisture rice) on the right side, 5 ill C from SL test to 5 apricot is selected.
1) When the diodes 14 & ~ 14e light up, the raw motor 5 is operated at a constant current value, the average current value becomes high, and the resistance of the resistor 6 increases, increasing the efficiency for milling hard rice such as brown rice. be able to.

This invention is as described above.
By operating 5, rice can be milled automatically at the appropriate pressure depending on the hardness of brown rice due to differences in dryness, etc., and the occurrence of broken rice due to too much pressure. Efficient rice milling can be carried out without causing a decrease in efficiency due to low grain size or low yield.
