Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a specific gravity destoner for rice processing. Background Technology

[0002] A gravity destoner is a machine that separates impurities such as stones from grains based on the difference in specific gravity and suspension velocity of grains. When the gravity destoner is working, the material continuously enters the middle of the screen from the feed inlet. Due to the vibration of the screen surface and the effect of the airflow through the material layer, the porosity between the particles increases and the material is in a fluidized state. This allows for the screening of rice and stones. The weight of the stones in the rice is greater than the weight of the rice, so the gravity destoner needs to screen and remove the heavier stones.

[0003] Existing gravity destoners require workers to unload entire bags of rice at once, resulting in a large amount of rice accumulating on the destone plate, leading to low work efficiency. Furthermore, they require high-power motors to vibrate the destone plate, resulting in higher manufacturing costs. Utility Model Content

The bevel gear is fixedly mounted on the outer side of the auxiliary shaft and the rotating shaft, with adjacent bevel gears meshing. The impact block is fixedly mounted on the outer side of the auxiliary shaft and abuts against the destone plate.

[0012] By adopting the above technical solution, the bevel gear allows the rotating shaft to drive the auxiliary shaft to rotate after rotation, and the auxiliary shaft can drive multiple striking blocks after rotation.

[0013] Preferably, the guide cylinder has an installation groove, and the inclined feeding pipe is fixedly installed inside the installation groove, wherein the inclined feeding pipe is inclined.

[0016] By adopting the above technical solution, after the fan is started, it can blow the rice produced inside the gravity destoner. Since the stones in the rice are relatively heavy, the airflow can only blow the rice.

[0023] 2. This utility model utilizes a high-frequency vibration component in its gravity destoner. The high-speed rotating drive shaft drives the rotating shaft via a synchronous pulley and belt. After the rotating shaft rotates, it drives the auxiliary shaft via a bevel gear. The auxiliary shaft drives multiple striking blocks to strike the second mounting frame. The second mounting frame can be displaced after being struck and can reciprocate via a spring. This keeps the material in an active state of motion on the high-frequency vibrating destoner plate, enhancing the interaction between the material, the destoner plate, and the airflow. This helps the material to stratify according to its specific gravity. Turning on the fan allows the airflow to blow the lighter rice towards the grain outlet pipe and discharge it from there, while the heavier stones will fall from the stone outlet pipe. This achieves the effect of separating rice and stones in the device. Attached Figure Description

[0033] The uniform feeding assembly 1 of the gravity destoner includes a first mounting frame 11, a motor 12, a drive shaft 13, a gear reducer 14, a movable shaft 15, and a conveying auger 16.

The synchronous wheel 23 is fixedly installed on the outer side of the rotating shaft 22 and the drive shaft 13, respectively. The synchronous belt 24 is tensioned and sleeved on the outer side of the synchronous wheel 23. The decelerated conveying auger 16 can make the rice more stable during the conveying process. The high-speed rotating drive shaft 13 can drive the rotating shaft 22 to rotate through the synchronous wheel 23 and the synchronous belt 24. After the rotating shaft 22 rotates, it can drive the auxiliary shaft 28 to rotate through the bevel gear 29.

[0037] In this embodiment, the high-frequency vibration component 2 of the gravity destoner also includes a spring 25, a second mounting bracket 26, and a destone plate 27.

[0038] In this embodiment, the high-frequency vibration assembly 2 of the gravity destoner also includes an auxiliary shaft 28, a bevel gear 29, and an impact block 30. The auxiliary shaft 28 is rotatably mounted on the inner side of the gravity destoner housing 7.

After rotating, the elliptical striking block 30 can cause the second mounting bracket 26 and the stone removal plate 27 to vibrate regularly without damaging the auxiliary shaft 28. The striking motion of the striking block 30 on the stone removal plate 27 is transformed into the reciprocating motion of the stone removal plate 27, and the rice can vibrate above the stone removal plate 27 with a large amplitude through the airflow.

[0042] In this embodiment, a feeding trough is provided on the top of the destoner housing 7, and the inclined feeding pipe 6 is connected to the feeding trough; the feeding trough allows the inclined feeding pipe 6 to feed rice into the interior of the destoner housing 7.

Movable shaft 15 then drives conveyor auger 16 to lift the rice inside rice storage bin 4 and discharge it through inclined discharge pipe 6 into the gravity destoning machine housing 7. The reduced speed of conveyor auger 16 ensures more stable rice transport during the process. Meanwhile, the high-speed rotating drive shaft 13 drives rotating shaft 22 to rotate through synchronous pulley 23 and synchronous belt 24.

Turning on the fan 17 can blow the lighter rice to the stone discharge pipe 9 and discharge it from the stone discharge pipe 9, while the heavier stones will fall from the grain discharge pipe 8, which can realize the diversion effect of the device on rice and stones.
