Market demand is very big.Rice is put into be ground polishing in polishing rice machine when, rice need and polishing rice machine
In polishing roll contacted, polishing roll realizes the grinding and polishing to rice during rotation.When rice is by polishing
After roller grinding and polishing, inevitably produce a certain amount of crack rice, it is contemplated that the price and the price variance of whole rice cracked rice compared with
Big situation (price of cracking rice is only the half of whole the price of rice lattice), people can use up when being polished with polishing rice machine to rice
Amount reduces the generation cracked rice, and reduces broken rice rate as far as possible.
At present, the different types of rice of kind about more than 5000 in the world, it is country variant, different regions, different types of
Water content, length and the hardness of paddy differ, if the rice (such as long-grained nonglutinous rice) of south China is mostly the long grain of rice, water content compared with
Few, hardness is relatively low, and the rice (such as polished rice) of northern China is mostly the circle grain of rice, and water content is more, and hardness is higher.
Existing polishing rice machine when being polished to rice, consideration be all polishing roll length, water injection system
The influence to broken rice rate such as performance, without considering influence of the rotating speed of polishing roll to broken rice rate.At present, people are universal
Think, the rotating speed of polishing roll only influences whether the processing efficiency of rice, as long as the rotating speed of rice polishing roller is controlled in a conjunction
In the range of reason, then broken rice rate would not be affected, and therefore, people are to use when being polished to rice at present
The rotating speed (750-800 revs/min) of same grade.
The content of the invention
The first object of the present invention is to overcome the weak point of background technology, and polishing can be automatically controlled by providing one kind
The polishing rice machine of roller rotating speed.
The second object of the present invention is to overcome the weak point of background technology, and polishing can be automatically controlled by providing one kind
The autocontrol method of the polishing rice machine of roller rotating speed.
In order to realize above-mentioned first purpose, the technical scheme is that：The rice that polishing roll rotating speed can be automatically controlled is thrown

The input connection of polishing roll, the discharge end of feed hopper are corresponding with polishing roll, it is characterised in that：Also include digital governer and three
Phase inverter device, the motor are three phase alternating current motor or three-phase variable frequency motor, and Material Sensor, polishing roll are provided with feed hopper
On output end speed probe is installed, the output end of described digital governer one end and polishing roll connects, the other end and three
The first frequency conversion port on phase inverter device is connected, and the second frequency conversion port on three phase converter is connected with three-phase alternating-current supply, and three
The input connection of the 3rd port and motor on phase inverter device.
In order to realize above-mentioned second purpose, the technical scheme is that：The rice that polishing roll rotating speed can be automatically controlled is thrown
The autocontrol method of ray machine, it is characterised in that it comprises the following steps, step 1：Three rotating speeds are set on digital governer
Gear button, three gear rotating speed buttons correspond to the rotating speed of three kinds of different stalls respectively, wherein, the rotating speed of three kinds of gears is respectively
400-500 revs/min, 600-700 revs/min and 700-800 revs/min；Step 2：According in polishing rice machine service manual
Regulation, and the place of production of rice to be processed, water content and shape select suitable rice processing rotating speed, and on digital governer
Select a kind of suitable rice processing gear；Step 3：Rice is sent in feed hopper, and allows polishing roll to throw rice
Light；Step 4：The signal being each collected into is sent to digital governer, digital governer by Material Sensor and speed probe
The signal being collected into according to Material Sensor and speed probe, the rotating speed of polishing roll is adjusted again, polishes rice
Roller keeps constant rotating speed.
The present invention can use the rotating speed of three kinds of grades to be polished rice, realize that the polishing to variety classes rice needs
Ask, broken rice rate can be reduced.
