Description
Technical Field
The invention belongs to the technical field of agricultural rice hullers, and particularly relates to a self-feedback automatic compensation rice huller.
Background
With the current population rise, the food supply demand is increasing. According to field investigation and the reaction of grain factory personnel, the key components used for shelling at present are two large rubber rollers with the same initial radius, the working condition of the rice huller is three shifts, and the rice huller continuously works for 24 hours, so that the rubber rollers are greatly abraded, the service life of the rubber rollers is generally changed once in 3-6 days, a person is required to manually adjust the distance between the rotating shafts of the two rubber rollers regularly, and the distance between the opposite surfaces of the two rubber rollers is strictly controlled, so that the shelling rate and the yield of rice are related. So traditional rice huller production efficiency is low, and product quality is unstable, operates inconveniently, needs personnel to guard in real time, brings a large amount of human resources's waste.
According to the related technical data and field investigation, the surface rotation speed difference V1-V2 of the two rubber rollers is required to be constant when the surface rotation speed difference V1-V2 is △ V, the output V1+ V2 is also required to be constant, and the distance between the opposite surfaces of the two rubber rollers is required to be constant.
The prior rice huller exists some drawbacks at present:
1) the existing new-generation rice huller drives one rubber roller to move close to the other rubber roller by means of movement of two synchronous hydraulic cylinders, but has the defects that the shafts of the two rubber rollers cannot be ensured to be parallel, and the error of the movement distance is large because the synchronous hydraulic cylinders have large errors during movement;
2) also, by consulting manufacturers, it is known that the fast roll may act by rice grains to increase the speed of the slow roll, while the fast roll is slower and there is a fluctuation in the instantaneous speed of the two rolls. This has a serious influence on the husking rate and yield
3) Because two rollers can wear during operation, and the radius wear degree of the two rollers can be different, the surface linear velocity of the two rollers can be changed under the condition that the rotating speed is not changed.
Therefore, it is necessary to design a novel automatic rice huller capable of automatically detecting the wear of the two rubber rollers and automatically compensating the distance.

After the time interval △ T, the processing module controls the approaching motion servo motor 101 on the first measuring module 1 and the second measuring module 2 to drive the longitudinal threaded rod 103 to rotate at a high speed and drive the threaded slider 104 to move rapidly, so that the main sensor 107 on the first measuring module 1 and the second measuring module 2 rapidly approaches the fixed rubber roller 3 and the movable compensation rubber roller 4 from the original points O1 and O2 respectively, thereby saving the measuring time, and simultaneously, the processing module starts to record the rotating speed n1 of the approaching servo motor 1011、n21。
When the anti-collision rollers 1054 of the anti-collision sensors 105 on the first measurement module 1 and the second measurement module 2 are firstly contacted with the outer surface buses of the fixed rubber roller 3 and the moving compensation rubber roller 4 to drive the rollers 1054 and the anti-collision induction squirrel cage winding 1053 to rotate to generate induction current, the anti-collision induction electrodes 1052 measure and transmit electric signals to the processing module, the positions where the main sensor 107 reaches are defined as Y1 and Y2, and the processing module records the number n1 of turns of the servo motor 101 at the moment1(Y)、n21And (Y) recording the positions of Y1 and Y2 points (because the moving distance is equal to the circle speed multiplied by the precise thread pitch), controlling the approaching servo motor 101 by the processing module to drive the longitudinal threaded rod 103 to rotate at a low speed, so that the main sensor 107 approaches slowly, preventing the surface of the roller 1071 from being crushed and worn by a rubber roller, and simultaneously enabling the anti-collision sensor 105 to rotate backwards due to the buffering effect of the buffering torsion spring 1056, so as to avoid damage to the anti-collision roller 1054.

So that the corresponding i-th measurement is performed with the initial horizontal center distance LCiConstant height difference H, R1Ci、R2CiThe initial radius of the ith measurement, the change in radius Δ R1i, Δ R2i of the ith measurement,
when two new rubber rollers are installed for the first time and run for a specified time interval, the first abrasion measurement is carried out, the transverse servo motor drives the main sensor to move in the direction parallel to the rubber roller bus, the radius of the point is measured every time the point is moved by m/N distance, and the N equidistant points on the R1 and R2 rubber roller bus which are measured in sequence are recorded by the simultaneous processing module

According to the formula:
calculating the average radius of the R1 and R2 rubber rollers
