On the other hand, the magnet switch 270 is attached to the outside of the weighing tank 200, and the link 280 is connected and installed between the magnet switch 270 and the discharge shutter 290 by the operation of the magnet switch 270. The discharge shutter 290 is to open and close.

The magnet switch 270 that opens and closes the discharge shutter 290 is operated by a signal applied from a control unit. In this control unit, rice is provided in the space 210 of the weighing tank 200 in addition to the limit switches 470 and 472. When the overflow falls to the bottom, the sensor 700 for detecting this is installed in the lower portion of the weighing tank 200, the sensor 700 is operated by the impact of the falling rice to send a signal to the control unit, the control unit receives the discharge While operating the magnet switch 270 connected to the shutter 290, the nozzle 440 is advanced by driving a motor (not shown) for rotating the crank 460.

The present invention configured as described above is to open the cover 110 of the upper portion of the rice storage tank 100 can be stored by putting a large amount of rice in the storage unit 120, when the rice is dropped into the storage unit 120 Since the rice hits the upper surfaces of the guide plates 130 and 132 attached to the middle portion of the storage unit 120 and is dispersed and lowered to both sides, the rice can be prevented from accumulating to the center of the storage unit 120 and the storage unit. 120 will not directly hit the nozzle 440 of the pressure-feeding means 400 is installed in the lower can prevent the damage.

Since the storage unit 120 is thoroughly blocked from the outside, it prevents the rice from being deteriorated by the external moisture or the proximity of the rats or other pests, thereby preventing the rice from being damaged or contaminated. Can be stored.

In order to supply a predetermined amount of rice in a state in which a sufficient amount of rice is stored in the storage 120, an operator operates an adjustment lever 600 attached to the lower side of the weighing tank 200 to control the inside of the tubular body 610. By adjusting the length of the rod 620 protruding into the space 250 by adjusting the rod 620 up and down, the volume of the space 250 can be added or subtracted. When the switch is operated, the control unit operates the blower 410 of the pressure feeding means 400 to inject air to the nozzle 440. At the same time, the crank 460 rotates so that one end of the crank 460 is eccentrically fixed. The link 464 pulls the nozzle 440 to operate the nozzle 440 backward as shown in FIG. 5.

The nozzle 440 maintains a state in which its tip is fitted to the inlet pipe 450 and then leaves the outside, so that high-speed air injected from the nozzle 440 is ejected into the inlet pipe 450. The pressure inside the pipe 450 is relatively lower than the pressure in the reservoir 120 according to the Berunui principle.

When the pressure of the inlet pipe 450 is lowered, the air in the storage unit 120 is sucked into the inlet pipe 450 to compensate for the pressure in the inlet pipe 450, and the rice in the storage unit 120 is At the same time it is sucked into the inlet pipe 450.

Rice and air sucked into the inlet pipe 450 is introduced into the inlet 220 of the metering tank 200 installed on the top of the rice storage tank 100 by the inlet pipe 450 to be dropped into the space 250. .

Meanwhile, air pressurized to the space portion 250 of the weighing tank 200 is discharged through a through hole drilled in the mesh body 240 forming the space 250, and one end of the air is discharged to the upper portion of the weighing tank 200. It is discharged to the connected return pipe 500 and back to the rice storage tank 100 so that the pressure in the rice storage tank 100 can be kept constant.

When the rice in the storage unit 120 is filled to fill the space 250 of the metering tank 200, the rice overflows to the outside of the inlet 220, and the overflowed rice again stores the rice storage tank 100. It will fall to 120.

When the rice overflows while the rice is filled in the space 250 of the weighing tank 200, the sensor 700 installed in the lower part of the weighing tank 200 senses this and signals the controller to full rice. The control unit receives this signal and rotates the crank 460 of the feeding means 400 so that the nozzle 440 is advanced so that the tip of the nozzle 440 is inserted into the inlet pipe 450. The operation of the blower 410 is stopped to prevent air from being sprayed so that no more rice is supplied.

The degree of rotation of the crank 460 by separating the contact of the limit switch (470,472) while the projection 462 formed on one outside of the crank 460 is in contact with the limit switch (470,472) provided on the outside of the crank 460 Each stops at the maximum forward and backward positions.

In addition, the control unit is opened by rotating and lifting the discharge shutter 290 that was kept in a blocked state by operating the magnet switch 270 attached to one outside of the weighing tank 200 so that the link 280 is pulled out. Thus, the rice metered in the space 250 of the metering tank 200 is discharged to the dry or wet semi-device of the next process not shown in the discharge chute 232.

When the discharge shutter 290 is opened, the discharge wire 292 attached to the inside of the discharge shutter 290 is also pulled out and discharged, so that the rice accumulated in the compressed state in the discharge chute 232 is easily discharged. The wire 292 is to prevent the bottleneck occurs on the discharge chute 232 side of the discharge of the rice and to allow the rice to be discharged smoothly.

When the rice inside the metering tank 200 is completely discharged again, the magnet switch 270 operates in reverse to the above, so that the discharge shutter 290 is blocked and waits for pressure of the next rice. Repeatedly, the continuous and quantitative rice feeding, weighing and discharging can be automatically performed.

As described above, the present invention can store a large amount of rice in a state of being stored in the storage unit 120 of the rice storage tank 100 in a clean and safe manner, and the rice in the storage unit 120 is sprayed at a high speed by the feeding means 400. The air is automatically transferred to the space 250 of the weighing tank 200 through the discharge hose 300, and the rest of the rice which is supplied to the space 250 and accumulated quantitatively falls back to the rice storage tank. By detecting that the rice is full in the space 250 by dropping the rice, it blocks the supply of more rice and opens the discharge shutter 290 to supply the quantitative rice to the semi-processing device of the next process. Will be done.

The present invention, as described above, by automatically conveying the quantitative rice by the conveying means to the weighing tank which can add or subtract the volume from the rice storage tank that can store a large amount of rice at once, clean and safe, the quantitative rice is transported to the weighing tank When completed, the operation of the transport means to stop and at the same time open the discharge shutter to supply the rice to the next process, according to the present invention can be stored safely and cleanly avoiding the attack of moisture and rats or other pests in large quantities Therefore, it is possible to solve the hygiene problems that were held when storing rice in a conventional bag state and at the same time, it is possible to prevent the waste of manpower and make the work smoothly because it is not necessary to carry the bag at all times. Since rice is automatically supplied to the weighing tank by the conveying means, separate manpower is used. Of course, there is no need to do it, and the bottom part of the weighing tank is equipped with a sensor that detects the falling rice when the rice is filled in the space, stopping the operation of the conveying means and opening the discharge shutter. It is possible to solve the problem of the occurrence of errors and loss of rice, which may occur when the rice is transported and weighed by the conventional manpower, and also has the advantage of providing a smooth food service.
