Technical Field

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

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, gear type rice mills capable of adjusting the degree of whiteness of rice have been 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 rice mill 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 to relieve the pressure, but the problems of unsmooth pulling and blockage exist generally.

Disclosure of Invention

The invention aims to: the utility model provides a gear formula regulator for rice mill, solves the problem that current rice mill gear regulator release is not smooth, the release is easy to be stuck.

The technical scheme adopted by the invention is as follows:

the utility model provides a gear position formula regulator for rice mill, the hand wheel comprises a hand wheel, the release pull rod is installed at the hand wheel center, it is equipped with hob and lower hob still to overlap on the release pull rod, go up the helicoid of hob and the helicoid looks adaptation of hob down, it is connected with hand wheel connection to go up hob, it establishes and installs the hand wheel seat to go up the hob outer still cover, it is equipped with the guide ring outward still to overlap down the hob, the guide ring is connected with hand wheel seat, the mounting hole has still been seted up along the radial direction of guide ring on the global of guide ring, install guide screw in the mounting hole, set up the bar groove with guide screw looks adaptation on the hob down, the release pull rod is kept away from hand wheel one end and still is installed the fender rice board, it is equipped with fender rice board spring to lie in between.

Furthermore, a spring guide plate is sleeved between the rice baffle spring and the guide ring on the pressure relief pull rod, and a spring positioning plate is sleeved between the rice baffle spring and the rice baffle plate on the pressure relief pull rod.

Furthermore, the end part of the pressure relief pull rod, which is close to one side of the hand wheel, is also connected with a pull ring.

Further, the upper screw rod is connected with the hand wheel through a fastening screw.

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

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

1. the rice noodle pressing device comprises a hand wheel, a pressure relief pull rod is arranged in the center of the hand wheel, an upper screw rod and a lower screw rod are further sleeved on the pressure relief pull rod, the screw surface of the upper screw rod is matched with the screw surface of the lower screw rod, the upper screw rod is connected with the hand wheel, a hand wheel seat is further sleeved outside the upper screw rod, a guide ring is further sleeved outside the lower screw rod and connected with the hand wheel seat, mounting holes are further formed in the circumferential surface of the guide ring along the radial direction of the guide ring, guide screws are mounted in the mounting holes, a strip-shaped groove matched with the guide screws is formed in the lower screw rod, a rice noodle blocking plate is further mounted at one end, away from the hand wheel, of the pressure relief pull rod, a rice noodle blocking plate spring is further sleeved between.

Through this setting, hand wheel dextrorotation reaches the initiating bit, because the hand wheel is connected with last hob, and the hand wheel keeps synchronous revolution with last hob, and fender rice leaf spring reaches ultimate length this moment, is in no pressure state, goes up hob and lower hob and is in inseparable interlock state, becomes a cylinder. Anticlockwise rotation gear, the helicoid atress extrusion of going up hob and lower hob begins spiral angular motion, and lower hob is ended in the bar inslot of lower hob by the direction screw on the guide ring this moment, can not follow the hand wheel rotation, can only the axial be linear motion, and its motion limit distance equals the spiral helical pitch of design, and in this motion limit distance, this distance is equallyd divide by the gear number of design on the hand wheel, forms the gear. The linear distance of the lower screw rod acts on the rice baffle spring and then is applied to the rice baffle, so that the rice baffle is displaced, the distance between the rice baffle and the discharge hole is changed, and the adjustment process of the gears is completed. When the pressure applied by a user accidentally exceeds the designed pressure of the whole machine or mechanical overload or crash caused by the voltage change of the power grid, the pressure relief pull rod can be pulled to relieve the pressure through the pull ring in the middle of the pull wheel. The pressure relief pull rod is designed at the center of the hand wheel for pressure relief, so that the problems of unsmooth pulling and blockage caused by the fact that the pressure relief pull rods of the same type are not arranged at the center are effectively solved. The multi-gear adjustment of the rice mill within the range of 270 degrees by the hand wheel is realized by using a simpler structure and fewer elements.

2. According to the rice baffle plate spring, the spring guide plate is sleeved between the rice baffle plate spring and the guide ring on the pressure relief pull rod, and the spring positioning plate is sleeved between the rice baffle plate spring and the rice baffle plate on the pressure relief pull rod. Through the arrangement, when the gear is adjusted, the linear distance of the movement of the lower screw rod acts on the spring guide plate and then the rice baffle plate is applied to the rice baffle plate spring, so that the process that the rice baffle plate spring is pressed by the lower screw rod to enable the rice baffle plate to move is more stable and reliable.

3. In the invention, the end part of the pressure relief pull rod, which is close to one side of the hand wheel, is also connected with a pull ring. Through this setting, be convenient for people to stimulate the release pull rod.
