Description

Technical Field

[0001] The utility model relates to the technical field of grain processing equipment, in particular to a rice husk grain lifter. Background Art

[0002] The husk extractor is mainly used in conjunction with a rice husk machine to extract full grains, rough and broken rice, imperfect grains and shriveled grains from a rice husk mixture. The husk extractor mainly utilizes the principle of wind selection to separate the rice grains, shriveled grains and imperfect grains with higher specific gravity from the rice husk and collect them separately according to the different specific gravities of the rice husk, rice grains, shriveled grains and imperfect grains.

[0003] The prior art discloses an improved grain lifter with application number CN201922228032.8. The improved grain lifter of the utility model uses a negative pressure vent located above a box body and utilizes gravity to suck out rice husks and dust mixed in the rice. Compared with the existing grain lifter, it has a better separation effect and improves the purity of the rice.

[0004] The above patent can separate grains from rice husks. However, although the concave conveyor belt in the middle can prevent the rice from bouncing to both sides and spilling when it falls from the feed port onto the conveyor belt, it will cause the grain to accumulate in the concave, resulting in part of the rice husks being wrapped in the rice, making it difficult for the negative pressure vent to suck out the rice husks. Although the problem is solved by a vibration motor, a high-power vibration motor is required to vibrate the entire box, which will generate huge noise and affect the hearing of workers working in the working environment. There are certain disadvantages. Utility Model Content

[0027] Reference Figure 2 , wherein an extension slide 21 is fixedly installed on the feed hopper 2 , and one end of the extension slide 21 extends to the top of the conveyor belt 5 .

[0028] With the above-mentioned structural arrangement, after the processing starts, the grain is poured into the hopper 2, and the grain in the hopper 2 slides directly onto the conveyor belt 5 along the extended slide 21, thereby preventing the grain from bouncing when falling from a height and falling outside the conveyor belt 5 to be wasted.

[0029] Reference Figure 2-5, wherein driving rollers 52 are rotatably installed at both ends of the conveyor belt 5, a first motor 51 is fixedly installed inside the installation cabinet 4, and the output end of the first motor 51 penetrates and extends to the inside of the box body 1, and is connected by the driving roller 52 in the conveyor belt 5;

[0030] Through the above-mentioned structural arrangement, the first motor 51 is started, and the first motor 51 drives the driving roller 52 to make the conveyor belt 5 start to move, so as to transport the food thereon.

[0031] Reference Figure 2-5 , wherein a plurality of supporting rollers 6 are rotatably mounted between the two driving rollers 52, a plurality of convex plates 7 are irregularly mounted on the outer sides of the plurality of supporting rollers 6, and one end of the plurality of supporting rollers 6 penetrates and extends to the interior of the mounting cabinet 4;

[0032] Through the above-mentioned structural setting, the support roller 6 is used to assist in supporting the conveyor belt 5 so that it remains stable when transporting grains. As the support roller 6 rotates, the protrusion plate 7 turns over the grains on the conveyor belt 5 to prevent rice husks from being pressed on the bottom of the grains and unable to be absorbed, thereby effectively cleaning the rice husks pressed by the grains.

[0033] Reference Figure 2-4 , wherein the transmission assembly 8 includes a second motor 81, the second motor 81 is fixedly installed inside the installation cabinet 4, a transmission rod 82 is rotatably installed inside the installation cabinet 4, one end of the transmission rod 82 is connected to the output end of the second motor 81, a plurality of belt grooves 83 are fixedly installed on the outer sides of the transmission rod 82 and the support roller 6, and the positions of the belt grooves 83 on both are located on the same straight line, and the insides of the transmission rod 82 and the belt grooves 83 on the support roller 6 are both connected through a transmission belt 84;

[0034] Through the above-mentioned structural setting, the second motor 81 is started, and the second motor 81 drives the transmission rod 82 to rotate. The transmission rod 82 drives the supporting roller 6 to rotate through the transmission belt 84, so that the protrusion plate 7 on the supporting roller 6 turns the grain on the conveyor belt 5.

[0035] Reference Figure 2-3 , wherein a comb tooth 91 is installed on the side of the scraping plate 9 facing the conveyor belt 5, and an angle limit seat 92 located on the right side of the scraping plate 9 is fixedly installed on the top of the inner side of the box body 1;

[0036] Through the above-mentioned structural arrangement, when the grain moves on the conveyor belt 5, the scraper plate 9 will scrape the excessively accumulated grain flat through the comb teeth 91 thereon, reduce the thickness of the grain accumulation and expose the internal rice husks, which is convenient for the negative pressure air outlet 10 to absorb. The angle limit seat 92 limits the angle at which the scraper plate 9 can be tilted to adjust the thickness of the grain scraped on the conveyor belt 5, and at the same time supports and limits the scraper plate 9 to ensure the scraping effect.

[0037] Working principle:

[0038] The first step to implement the innovation point:

[0039] Step 1: After the processing starts, the grain is poured into the hopper 2, and the grain in the hopper 2 slides directly onto the conveyor belt 5 along the extended slide 21, and the first motor 51 is started at the same time, and the first motor 51 drives the driving roller 52 to make the conveyor belt 5 start to move, so as to transport the grain thereon;

[0040] Step 2: When the grain moves on the conveyor belt 5, the scraper plate 9 scrapes the excessively accumulated grain flat through the comb teeth 91 thereon, reduces the thickness of the grain accumulation and exposes the rice husks inside, which is convenient for the negative pressure vent 10 to absorb. At the same time, the second motor 81 is started, and the second motor 81 drives the transmission rod 82 to rotate. The transmission rod 82 drives the supporting roller 6 to rotate through the transmission belt 84, so that the protrusion plate 7 on the supporting roller 6 turns over the grain on the conveyor belt 5 to avoid the rice husks being pressed on the bottom of the grain and unable to be absorbed, and the rice husks pressed by the grain are effectively cleaned.
