[0002] After the rice is processed, it needs to be weighed quantitatively so that it can be packaged into products of different weights to meet the different needs of consumers.

[0003] A search revealed a patent document with authorization announcement number CN207515896U, which discloses a quantitative rice weighing device. The device includes a weighing platform with a display connected to it. A quantitative rice weighing hopper is positioned on the platform, with several slots on the side wall of the hopper and corresponding slots on its inner wall. Insert plates are inserted into the slots and fixed to the hopper by fasteners. A flexible, sliding baffle is located inside the hopper at each slot; when the plate is inserted, the baffle contacts it; when not inserted, the baffle seals the slot. This simple yet ingenious design allows for precise metering of rice according to different bag sizes, facilitating bagging and improving work efficiency.

Therefore, we have proposed a rice quantitative weighing device to solve the above problems. Utility Model Content

[0041] Specifically, the conveying mechanism includes a conveying shaft 401 and a spiral blade 402.

[0042] Specifically, the second transmission mechanism includes two second transmission wheels 204 and a second transmission belt 205.

[0043] Specifically, the clamping mechanism includes two hydraulic cylinders 802 and a pressure plate 803. The hydraulic cylinders 802 are fixedly installed on the outside of the fixed frame 801. The output shaft of the hydraulic cylinders 802 extends into the fixed frame 801. The pressure plate 803 is provided inside the fixed frame 801.

[0044] Specifically, a slide rod is fixedly installed on the outside of the pressure plate 803, and the other end of the slide rod extends to the outside of the fixed frame 801, and the slide rod is slidably connected to the fixed frame 801.

[0045] Specifically, a controller is installed on the front side of the function box 2, and the controller is electrically connected to the weighing platform 7, the motor 201, and the solenoid valve.

[0046] In this application, during use, rice is first poured into the top inlet of the storage bin 3. The operator then sets the target weight using the controller on the front side of the function box 2 and starts the motor 201. The output shaft of the motor 201 drives the stirring shaft 301 to rotate inside the storage bin 3, and the stirring rod 302 on it continuously stirs the rice, effectively preventing the rice from clumping or bridging due to accumulation, and ensuring smooth feeding. At the same time, the stirring shaft 301 can transmit the rotational power through the first transmission mechanism composed of two first transmission wheels 202 and a first transmission belt 203. The rice is fed to the rotating shaft 501, which drives the multiple baffles 502 inside the feeding tube 5 to rotate. The baffles 502 evenly distribute the rice at a stable speed, which can accurately control the flow rate of the rice and avoid weighing errors caused by feeding too fast or too slow. During this process, the rubber rod 503 at the bottom of the rotating shaft 501 periodically strikes the striking seat 504 at the bottom of the storage box 3 as the shaft rotates. The resulting vibration can further loosen the rice in the storage box and prevent the feeding blockage caused by rice sticking and accumulating.

[0047] The rice falling into the conveyor cylinder 4 is driven by the rotation of the shaft 501 to rotate the conveyor shaft 401 under the action of the second transmission mechanism composed of two second transmission wheels 204 and a second transmission belt 205. The spiral blades 402 on the shaft drive the conveyor shaft 401 to rotate smoothly from the left side to the right side of the conveyor cylinder 4, and then discharge it in an orderly manner through the discharge pipe 6. This achieves precise control of the rice conveying volume and ensures weighing accuracy. By placing the packaging bag on the placement box 8, the hydraulic cylinder 802 on the outside of the fixing frame 801 is activated. Its output shaft pushes the pressure plate 803 to slide inward, and the pressure plate 803 and the fixing frame 801 are used to slide inward. The inner wall of the frame 801 fits snugly, firmly clamping and fixing the packaging bag from both sides. This prevents the packaging bag from shifting, tilting, or even tipping over due to the impact of falling rice or vibration during conveying, ensuring the accuracy of the weighing data. The weighing platform 7 can monitor the weight of the rice inside the packaging bag in real time and feed the data back to the controller. When the weight reaches the preset value, the controller immediately sends a command to close the solenoid valve on the discharge pipe 6, cutting off the rice conveying path. At the same time, it controls the motor 201 to stop running, and all mechanisms stop working, thereby accurately completing the quantitative weighing process of rice.
