Technical Field

The invention belongs to the technical field of rice mill equipment, and particularly relates to a gear regulator hand wheel.

Background

Rice mills are mainly of three types: a separation type rice mill, a rice huller mill and an air jet type rice mill; the rice huller is a grain processing machine for hulling rice to prepare brown rice, and can hulle rice, reduce rice grain waist and skin damage, and keep brown rice intact as far as possible. The rice mill uses mechanical force to peel and whiten the brown rice. The rice huller and mill combined rice huller combines the rice huller and the rice mill together to form the rice huller and mill combined rice huller with rice hulling and milling functions.

With the increasing living standard of people, the requirement on food is high. Different people require differently to the whiteness degree of rice, some people like the rice of some on the white side, traditional rice huller grinds the whiteness degree that the combined rice mill is difficult to adjust rice in continuous work, directly discharge from the combined rice huller discharge gate of rice hulling mill after the rice husking mill is ground, if want to increase the whiteness degree of rice, generally add repeatedly processing or adjust the whiteness degree of rice through adjusting chaff separation strength and rice milling intensity etc. of whole device in the combined rice mill through the rice after will grinding many times, the operation is complicated, consume for a long time. Therefore, a position-blocking type rice mill capable of adjusting the whiteness of rice is developed. The rice whiteness control device controls the discharge time of rice by adjusting the gap between the rice baffle plate and the discharge hole, and then controls the whiteness of the rice. However, when the gear of the existing rice mill is adjusted, when the pressure applied by a user accidentally exceeds the designed pressure of the whole machine or mechanical overload or dead halt caused by the voltage change of a power grid, a pressure relief pull rod on a hand wheel needs to be pulled for pressure relief, and the existing pressure relief pull rod is not installed in the center of the hand wheel, so that the problems of unsmooth and unsmooth pulling are generally caused during pulling.

Disclosure of Invention

The invention aims to: the utility model provides a keep off position regulator hand wheel solves the release pull rod of installation on the current hand wheel and does not have the problem that the pulling that causes is not smooth, the card is dunked in hand wheel central point.

The technical scheme adopted by the invention is as follows:

a gear regulator hand wheel comprises a hand wheel body, wherein a circular groove is formed in one side end face of the hand wheel body, a plurality of hemispherical grooves used for mounting steel balls are distributed around the circular groove in an annular mode, a pressure relief hole used for mounting a pressure relief rod is formed in the center of the circular groove, and a mounting hole is formed beside the pressure relief hole.

Furthermore, two mounting holes are formed in the pressure relief hole, the circle centers of the two mounting holes and the circle center of the pressure relief hole are located on the same straight line, and the two mounting holes are symmetrically arranged relative to the pressure relief hole.

Further, the hand wheel body is in a flower ring shape.

Furthermore, the outer surface of the hand wheel body is coated with an anti-corrosion coating.

Furthermore, a buffering rubber pad is bonded on the end face of one side, far away from the hemispherical groove, of the hand wheel body.

Furthermore, a plurality of anti-skidding salient points are further arranged on the buffer rubber mat.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. the hand wheel comprises a hand wheel body, wherein a circular groove is formed in the end face of one side of the hand wheel body, a plurality of hemispherical grooves used for mounting steel balls are annularly distributed around the circular groove, a pressure relief hole used for mounting a pressure relief rod is formed in the center of the circular groove, and a mounting hole is formed beside the pressure relief hole. Through the arrangement, the pressure relief hole is formed in the center of the circular groove, so that the pressure relief pull rod mounted in the pressure relief hole can relieve pressure conveniently, and when the pressure applied by a user accidentally exceeds the designed pressure of the whole machine or mechanical overload or dead halt caused by voltage change of a power grid, pressure can be relieved through the pressure relief pull rod in the middle of the handle wheel body. The pressure relief hole for installing the pressure relief pull rod is designed in the center of the hand wheel body, so that the pressure relief pull rod is ensured to be installed in the center of the hand wheel body, and the problems of unsmooth pulling and blockage caused by the fact that the pressure relief pull rods of the same type are not arranged in the center of the hand wheel are effectively solved.

2. In the invention, two mounting holes are formed, the circle centers of the two mounting holes and the circle center of the pressure relief hole are on the same straight line, and the two mounting holes are symmetrically arranged relative to the pressure relief hole. Through this setting, be convenient for fix the hand wheel body, ensure that the hand wheel operation is stable.

3. In the invention, the outer surface of the hand wheel body is coated with an anti-corrosion coating. Through this setting, increased the corrosion resistance of hand wheel body, improved the life of hand wheel body.

4. In the invention, a buffering rubber pad is bonded on the end face of one side of the hand wheel body, which is far away from the hemispherical groove. Through this setting, people can support the buffering to the palm when the hand wheel is rotated in the operation to the buffering cushion, improve the operation travelling comfort.
