Problems solved by technology

There are some problems in this kind of feeding mechanism: 1. The screw that withstands the material roller shaft may become loose after long-term vibration of the machine, causing the material roller to stop rotating, which will not achieve the effect of uniform material but hinder the inflow of rice, affecting the normal operation of the rice huller. run
In case the screw falls off, it will fall between the two rubber rollers, damage the rubber rollers, and even bend their shafts, causing greater losses
2. The inner hole of the material roller matched with the material roller shaft is small and long. For the convenience of processing, a large-diameter hole is designed in the middle, but it is difficult to cast. For example, the diameter of the inner hole of the material roller of LM24-2C rice huller is 17 The length of mm is 164 mm, the diameter of the middle large hole is 30 mm and the length is 120 mm, the casting yield is low
3. The method of using spacer to realize the axial positioning of two bearings is also uneconomical

Embodiment Construction

[0009] The accompanying drawing is the feeding mechanism designed according to the LM24-2C rice huller. The outer rings of the two 6203 bearings 5 ​​are installed in the corresponding holes of the right wallboard 6 through the gland 4 and the plug 7 respectively. Its inner ring is contained on the journal corresponding to the two ends of the large cylinder in the middle of the material roller shaft 9 respectively, and the diameter of the large cylinder is 3 millimeters larger than the bearing 5 endopores. Gland 4 is installed on the right wallboard 6 with screws, and the outer circle of blocking 7 and the right wallboard 6 endoporus are tighter transition fits. The pulley 3 is mounted on one end of the material roller shaft 9 through a key, and the bolt 1 and the corresponding spring washer fix the pulley 3 and the bearing 5 through the stop pad 2 and the end face of the large cylinder in the middle of the material roller shaft 9; the material roller 10 is fixed with an elasti...

Abstract

A material driving mechanism for rice huller features that a belt wheel and a bearing are fixed to the end face of big cylinder on the axle of material driving roller via screw bolt, spring washer and stop pad, the material driving roller is installed to another end of said axle by elastic cylindrical pin, and said material driving roller has a small internal hole at one end and a big internal hole at another end.

Description

technical field [0001] The invention relates to a paddy processing equipment component, in particular to a feeding mechanism of a rice huller. Background technique [0002] Husker is an important equipment in rice processing equipment. Its main function is to process rice into brown rice. It is generally a rubber roller husker. Its principle is: the rice is sent into the middle of the rubber rollers with opposite directions and different rotating speeds through the feeding mechanism. Under the pressure and differential speed between the two rubber rollers, the outer shell (also called bran) of the rice is rubbed off to make brown rice. Therefore, the rice huller is an important machine in the complete set of rice milling equipment. The function of the feeding mechanism is to scatter the input rice evenly with the rotating material roller protruding on the surface, filling the whole length of the two rubber rollers. The material roller will have the same length as the rubb...
