Description

Technical Field

[0001] The utility model relates to the technical field of rice-rough separation, in particular to a gravity rice-rough separation device. Background Art

[0002] Brown rice separation is the process of separating brown rice from paddy rice in a mixture of brown rice and brown rice. This process, also known as "brown rice selection," aims to effectively separate brown rice from paddy rice for subsequent processing or use. Brown rice refers to rice that has had its husk removed but retains the cortex, aleurone layer, and germ, while paddy rice is rice that has not been hulled. The brown rice separation process plays a crucial role in rice processing, as it directly impacts the quality and intended use of the final product.

[0003] For example, a gravity grain-rough separation device with application number 202022236549.4 has rotatable storage boxes installed at the screening outlet and the miscellaneous material outlet of the gravity grain-rough separator body. Using a motor to rotate the rotating seat, other groups of storage boxes can be placed under the screening outlet or the miscellaneous material outlet to continuously collect and process the materials, improve the material collection effect, and increase the screening process speed. However, the device still has certain defects;

[0004] The rice bran is screened through the interior of the gravity rice bran separator body. When the rice bran is put in, a large amount of rice bran easily causes it to adhere to the inner wall of the gravity rice bran separator body, making it inconvenient to clean the inner wall of the gravity rice bran separator body, and resulting in waste of rice bran.

[0010] Preferably, the fan mechanism blows air downward, and the shaft end of the fan mechanism is connected to the first transmission shaft through a first connecting belt, and the first transmission shaft and the second transmission shaft are connected through a second connecting belt, and pulleys are installed on the first transmission shaft and the second transmission shaft, which limit the first connecting belt and the second connecting belt.

[0011] With the above structural design, the fan mechanism blows air to the inside of the grain box, thereby raising a large amount of dust in the grain box. When the first transmission shaft rotates, it can drive the second transmission shaft to rotate through the second connecting belt, and at the same time, the first connecting belt can rotate the fan mechanism.

[0012] Preferably, the second transmission shaft and the first transmission shaft are parallel to each other, and the first transmission shaft is connected to the output shaft end of the servo motor, the servo motor is fixed to the upper surface of the separation box, and the second transmission shaft and the first transmission shaft are both designed as rotating structures.

The interior of the grain box is staggered with guide plates, and the guide plates have an inclined structure design.

[0015] With the above structural design, the dust removal pump is started, and the dust removal pump sucks the dust raised in the grain box through the dust suction pipe, and transports the sucked dust to the dust box for storage through the dust exhaust pipe. The guide plate plays a role in guiding the input grains to prevent excessive accumulation of grains, which may cause the grain temperature to rise or agglomerate.

The rice husk box 2 is installed on the left side of the separation box 1, and the feed port 3 is installed on the left side of the rice husk box 2. The interior of the feed port 3 is designed in a conical structure. The rice husk box 2 is fed into the feed port 3 through the feed port 3.

When the servo motor 4 is started, the servo motor 4 drives the first transmission shaft 6 to rotate through the output shaft. The first transmission shaft 6 drives the fan mechanism 5 to rotate through the first connecting belt 8. The first transmission shaft 6 drives the second transmission shaft 7 to rotate through the second connecting belt 9. A dust box 10 is installed on the right side of the separation box 1. , and a dust removal pump 11 is installed on the dust box 10, and a dust suction pipe 12 and a dust exhaust pipe 13 are installed on the left and right sides of the dust removal pump 11 respectively.

When the dust removal pump 11 is started, the dust removal pump 11 sucks the dust raised in the grain box 2 through the dust suction pipe 12, and transports the sucked dust to the dust box 10 for storage through the dust exhaust pipe 13. The guide plate 14 plays a role in guiding the input grain to prevent excessive accumulation of grain, which may cause the grain temperature to rise or agglomerate.

[0034] A connecting strip 16 is installed below the rough rice box 2 through a connecting block 15, and a rice pouring plate 17 is installed below the connecting strip 16.

The upper opening of the rice husk box 18 is located at the lower right side of the sieve plate 24. The sieve plate 24 is designed with an inclined structure. After the rough rice passes through the sieve plate 24, the rice can fall into the rice pouring plate 17, and then the rice is discharged through the rice pouring plate 17, and the rice husk is located on the sieve plate 24. As the sieve plate 24 shakes, the rice on the sieve plate 24 is discharged. The husks can fall into the rice husk box 18 for collection.

The half gear 19 is fixedly connected to the second transmission shaft 7. When the second transmission shaft 7 rotates, the half gear 19 can be driven to rotate, and then the half gear 19 drives the rack 26 to move to the left. The rack 26 drives the n-shaped bar 23 to move to the left through the connecting rod 22, and the n-shaped bar 23 drives the sieve plate 24 below to move to the left. At this time, under the pulling action of the rack 26 and the connecting rod 22, the telescopic spring 25 is in a stretched state.

The first transmission shaft 6 drives the second transmission shaft 7 to rotate through the second connecting belt 9. The fan mechanism 5 blows air to the inside of the grain box 2, thereby raising a large amount of dust in the grain in the grain box 2.

[0036] When the second transmission shaft 7 rotates, it can drive the half gear 19 to rotate, and the rear half gear 19 drives the rack 26 to move to the left, and the rack 26 drives the n-shaped bar 23 to move to the left through the connecting rod 22, and the n-shaped bar 23 drives the lower screen plate 24 to move to the left. At this time, under the pulling action of the rack 26 and the connecting rod 22, the telescopic spring 25 is in a stretched state. When the gear end of the half gear 19 is away from the rack 26, the rack 26 and the connecting rod 22 are moved to the left under the action of the rebound force of the telescopic spring 25. The connecting block 15 drives the rice pouring plate 17 to vibrate through the connecting bar 16, thereby improving the rice feeding efficiency. At the same time, the connecting block 15 can drive the upper rice box 2 to vibrate, preventing the rice in the rice box 2 from adhering to the inner wall, which is inconvenient to clean.

[0037] The dust removal pump 11 sucks the dust raised in the grain box 2 through the dust suction pipe 12 and transports the sucked dust to the dust box 10 for storage through the dust discharge pipe 13.
