Description

Grain Automatic Weighing Device

The present invention relates to a grain automatic weighing discharging device, and more particularly, grains capable of automatically and continuously weighing the dried grains by a certain amount, and raising and lowering the weighed grains to a position where the bag can be easily transported by a worker. It relates to an automatic meter discharge device.

The conventional automatic grain weighing device for discharging the dried grain is provided with a grain container on the upper side, and a tank and plate manual balance for measuring the weight of the grain below the grain container.

The automatic grain dispensing device configured as described above discharges the desired amount of grain into the bag by the plate manual balance whose weight is set in advance. Therefore, the worker blocks the grain from being discharged from the grain container when the grain of the weight set in the plate manual balance is put in the bag, and moves the grain bag containing the quantitative grain. Then, a new empty bag is placed on the plate manual balance to repeatedly carry out the grain discharge operation.

By the way, in the grain discharging device as described above, it is very difficult to discharge the grain of the exact amount by the weight set in the plate manual balance in one operation. Thus, usually the bag had to contain an amount of grain in excess of the desired weight, and then the operator had to carry out additional work of removing the excess weight of grain from the bag.

In addition, since the plate manual cutlery uses weights, errors in the weighing of grains are severe and have been disadvantageous to consumers and sellers. In addition, in order to load or transport the finished grain sacks to another place, the worker had to lean his back and lift the grain sacks to shoulder height. Due to this, there is a drawback that the work efficiency of the worker is lowered, there is a problem that a lot of labor of the worker is made because all such work is made by hand.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is to automatically and continuously weigh the dried grains by a predetermined amount, the position that is easy for the operator to transport the finished grain bag The present invention relates to a grain automatic weighing discharging device capable of lifting up to.

The following briefly describes the operation of the automatic grain discharging device according to the present invention.

Figure 4a is a side cross-sectional view showing a state in which grain is supplied to the metering tank in the auxiliary tank shown in FIG.

Referring to Figure 4a, in order to drive the automatic grain discharging device 100 according to the present invention is first put grain in the auxiliary tank (200). In order to discharge the grain in the auxiliary tank 200 to the weighing tank 300, the operator operates the weighing operation button of the control box 600 (see FIG. 1). When the metering operation button is operated, the first solenoid 260 and the second solenoid 280 of the input device 250 mounted on the input unit 220 operate. The levers 268 and 288 coupled to the lower ends of the first solenoid 260 and the second solenoid 280 are raised upward. Then, the input door 222 is rotated to the rear side along the levers 268 and 288 around the first hinge 224, and as a result, the grain is discharged from the auxiliary tank 200 into the weighing tank 300. Since the door 222 is rotated to the rear, the operator can visually check the grain introduced into the weighing tank (300).

The first solenoid 260 and the second solenoid 280 are automatically shut off when the grain introduced into the weighing tank 300 matches the weight set by the operator. At this time, the input door 222 is closed by the restoring force of the springs 261 and 281 that are coupled to the coupling holes (269, 289) and the L-shaped holder (267, 287).

4B is a front view illustrating a state in which grain is supplied to the grain bag in the weighing tank illustrated in FIG. 1.

Referring to FIG. 4B, in order to discharge the grain of the weighing tank 300 to the outside, the bag is first fitted to the bag hanger rod 339. Then, the discharge operation button of the control box (not shown) is operated. When the discharge operation button is operated, the third solenoid 360 operates. Then, the opening and closing rod 370 moves to the third solenoid side along the guide hole 336a of the second side plate 336 and the guide pipe 375. At this time, the door plate 340 fixed by the opening and closing rod 370 is opened by the weight of the grain, and as a result, the grain is put into the grain bag.

When the input of grain into the grain bag is completed by the restoring force of the spring (368) connected to the b-shaped second holder (336b) opening and closing rod 370 along the guide pipe 375 and the guide hole (336a) toward the door plate 340 side And the door plate 340 is fixed as a result.

Figure 4c is a side view showing a state in which the grain bag is lifted by the lifting device after the discharge of grain is completed.

Referring to Figure 4c, when the grain is finished into the grain bag, the operator operates the lift switch. When the lift switch is operated, power is applied to the brake deceleration motor 540 installed in the third support end 116 to operate. As a result, the wire 550 extending from the brake reduction motor 540 and extending to the first wire wheel 112a and the second wire wheel 112b and the first support 530a of the lift 530 is a brake reduction motor. 540 is wound. The lift 530 then rises along the first guide rail 520 and the second guide rail 522. The lift 530 will ascend until the lift switch is released. Meanwhile, the lift 530 stops rising when detected by the second limit switch L2 (see FIG. 1) installed in the first guide rail 520. At this time, when the brake deceleration motor 540 stops, the worker moves the bag containing the grain to another place. When the lower switch is operated again, the brake deceleration motor 540 operates in the opposite direction, and the lift 530 descends until the lower switch is turned off. On the other hand, the lift 530 stops falling when sensed by the first limit switch L1 (see FIG. 1).

When the lift 530 is located at the bottom, the operator operates the weighing operation button again to continuously carry out the weighing and discharging work.

As described above, the automatic grain dispensing device of the present invention is provided with a control box that can control the first solenoid, the second solenoid and the third solenoid can automatically measure the grain. In addition, a load cell is provided so that a constant weight of grain is always contained in the bag, thereby providing reliability to consumers and sellers. In addition, the lifting device is provided so that the worker can easily transport the bag containing the grain to another place, there is an effect of improving the work efficiency of the worker.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims below. It will be appreciated that it can be changed.
