Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

A rice classifying system as shown in fig. 1 to 3 and 6, comprising a first rice classifying device 1, a second rice classifying device 3 and a rice classifying device 2 in the middle, wherein the first rice classifying device 1 has a mixture outlet connected with the inlet of the rice classifying device 2, the rice classifying device 2 has a mixture outlet connected with the inlet of the second rice classifying device 3, the rice classifying device 2 is a roller classifying machine with a plurality of groups of rollers, one end of each group of rollers is a driving device, the other end is a small granule collecting tank 4 for discharging, the small granule collecting tank 4 is connected with a chute shaft 5, the chute shaft 5 is connected with a screw shaft 6 through a bearing and passes through a guide cylinder device 7 at the end of the rice classifying device 2, then the end of the chute shaft 5 is connected with an angle indicating needle 8, one end of the angle indicating needle 8 is a tip, the other end is provided with a screw hole sleeve, the screw hole sleeve is internally connected with an adjusting rod 9, the adjusting rod 9 is provided with a lock sleeve 10, a hole sleeve 11 and a handle 12, the hole sleeve 11 is connected on a support plate 13, and the support plate 13 is rotatably connected on the guide cylinder device 7 through an angle adjusting support 14. The angle of the small-particle collecting tank 4 is adjusted according to the granularity requirement of the selected rice until the requirement is met.

In the above technical solution, the support plate is provided with a lock nut for fixing the adjusting rod 9. After the position of the small-particle collecting tank 4 is adjusted in place, the position of the adjusting rod 9 is fixed through the locking nut, and then the position of the small-particle collecting tank 4 can be fixed.

As shown by the broken line in fig. 4, when the machine is stopped, the variety needs to be changed or it is desired to clean the bottom of the small particle collecting tank, the lock nut is loosened and removed from the main body. Then the angle indicator needle is rotated to turn the bottom of the granule collecting groove. After cleaning, the collection trough is returned to the original position.

In the technical scheme, the guide cylinder device 7 of the roller fine separator 2 is provided with angle scales matched with the angle indicating needle 8.

In the above technical solution, the handle 12 is an embossed handle. The knurling handle can increase frictional force, is difficult to skid when adjusting.

The rice grading system is characterized in that a rice grading device is used for carrying out primary separation on raw grains to extract whole grains with different particle sizes, then the mixture containing a small number of whole grains is conveyed to a rice fine selection device, the mixture is subjected to secondary grading to extract the whole grains and the grains containing the extremely small number of whole grains, finally, the rice grading device of different models is used for carrying out finer grading treatment on the grains containing the extremely small number of whole grains, and the whole grains, the broken grains and the rice crushed products with smaller volumes are extracted.

The angle of the small-particle collecting tank is changed by adjusting the position of the handle for the materials flowing out of the upper-layer and middle-layer sieve cylinders, so that the mixture 2 is not mixed into the third-level rice.

When adjustment handle turned left, granule collecting vat connects the material mouthful to reduce, can accept more materials.

As shown in FIG. 5, when the adjusting handle is turned right, the small particle collecting groove receiving opening is lifted, and less material is received.

After the raw grains enter the rice grading device, the screening surfaces are uniformly distributed under the combined action of feeding pressure, gravity and centrifugal force. According to the difference of the grain granularity of the raw grain, screens with adaptive screen holes are prepared, materials move relative to the screen surfaces on the screen surfaces in a plane rotation mode, and are classified according to the granularity through continuous screening of a plurality of layers of screens (the screen holes are different in size), and the classified rice is divided into rice grains of different grades, such as first-grade rice (more than or equal to three quarters of the average length of the whole rice), second-grade rice (less than or equal to three quarters of the average length of the whole rice), small broken rice 1 (containing the whole grain rate less than or equal to 0.05), mixture 1 (containing a small amount of whole grains) and the like. The mixture 1 enters a rice fine-selecting device in the next procedure. The choice device of rice is by mainly taking a sieve section of thick bamboo of pocket hole, screw conveyer etc. constitute, 1 material of mixture gets into after the machine, less grain can fall into the pocket hole of a rotary screen section of thick bamboo, then these grain are taken to certain height, fall into the granule collecting vat, mixture 2 carries out sieve section of thick bamboo through screw conveyer and gets into different model rice grading plant once more and carry out more meticulous hierarchical processing, hierarchical level four rice and rice broken rice are gone out, and other materials that can not reach the height in the sieve section of thick bamboo are by another export tertiary rice of discharging.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
