Description
Technical field
A kind of structure of polishing rice machine is the utility model is related to, specifically one kind can automatically control polishing roll rotating speed
Polishing rice machine.
Background technology
At present, the polishing rice machine that polishing can be ground to rice surface is applied widely in grain machine industry,
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, a certain amount of crack rice inevitably is produced.In view of the price cracked rice and the price variance of whole 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 clock) of same grade.
Utility model content
The purpose of this utility model is to overcome the shortcoming of background technology, and polishing can be automatically controlled by providing one kind
The polishing rice machine of roller rotating speed.
To achieve these goals, the technical solution of the utility model is：The rice that polishing roll rotating speed can be automatically controlled is thrown
Ray machine, including polishing machine body, are provided with feed hopper, polishing roll and motor on the polishing machine body, the output terminal of motor with
The input terminal connection of polishing roll, the discharge end of feed hopper are corresponding with polishing roll, it is characterised in that：Further 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
Output terminal speed probe is installed, the output terminal of described digital governer one end and polishing roll connects, the other end and three-phase
The first frequency conversion port on frequency converter connects, and the second frequency conversion port on three phase converter is connected with 380 AC power of three-phase, and three
The input terminal connection of the 3rd port and motor on phase inverter device.
The utility model can use the rotating speed of three kinds of grades to be polished rice, and realizing needs different types of polishing
Ask, broken rice rate can be reduced.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
1- polishing machines body in figure, 2- feed hoppers, 3- polishing rolls, 4- motors, 5- digital governers, 6- three phase converters,
The first frequency conversions of 61- port, the second frequency conversions of 62- port, the 3rd frequency conversion ports of 63-, 7- Material Sensors, 8- speed probes, 9-

Embodiment
Describe the performance of the utility model in detail below in conjunction with the accompanying drawings, but they are not formed to the utility model
Limit, it is only for example.The advantages of making the utility model by explanation at the same time, is more clear and is readily appreciated that.
Understood refering to attached drawing：The polishing rice machine of polishing roll rotating speed, including polishing machine body 1, the throwing can be automatically controlled
Feed hopper 2, polishing roll 3 and motor 4 are installed on ray machine body 1, the output terminal of motor 4 is connected with the input terminal of polishing roll 3, into
The discharge end of hopper 2 is corresponding with polishing roll 3, it is characterised in that：Further include digital governer 5 and three phase converter 6, the motor
4 be three phase alternating current motor or three-phase variable frequency motor, and Material Sensor 7, the output terminal installation of polishing roll 3 are provided with feed hopper 2
There is speed probe 8, the three phase converter 6 is equipped with three frequency conversion ports, and three frequency conversion ports are respectively the first frequency conversion end
The 61, second frequency conversion port 62 of mouth and the 3rd frequency conversion port 63, described 5 one end of digital governer are connected with the output terminal of polishing roll 3,
The other end is connected with the first frequency conversion port 61 on three phase converter 6, the second frequency conversion port 62 and three-phase on three phase converter 6
380 AC powers 9 connect, and the 3rd port on three phase converter 6 is connected with the input terminal of motor 4.
In actual work, autocontrol method of the invention is as follows：It includes the following steps,
Step 1：Three rotating speed gear buttons are set on digital governer 5, and three gear rotating speed buttons correspond to three respectively
The rotating speed of kind different stalls, wherein, the rotating speed of three kinds of gears is respectively 450-500 revs/min, 650-700 revs/min and 750-
800 revs/min；
Step 2：According to the regulation in polishing rice machine service manual, and the place of production of rice to be processed, water content and shape
Suitable rice processing rotating speed is selected, and a kind of suitable rice processing gear is selected (such as selection first on digital governer 5
Shelves rotating speed, 400-500 revs/min is chosen to be by the rotating speed of polishing roll)；
Step 3：Rice is sent in feed hopper 2, and allows polishing roll 3 to be polished rice；
Step 4：The signal being each collected into is sent to digital governer by Material Sensor 7 and speed probe 8, number
The signal that regulation device 5 is collected into according to Material Sensor 7 and speed probe 8, again adjusts the rotating speed of polishing roll 3
Section, the rotating speed (rotating speed of polishing roll is such as chosen to be 480 revs/min) for keeping constant rice polishing roller.
Other unaccounted parts belong to the prior art.
