Description

Gear type regulator for rice mill
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
There are three main types of rice mills: a separation type rice mill, a rice milling combined rice mill and a wind-spraying type rice mill; the rice huller is a grain processing machine for removing chaff from rice to prepare brown rice, which can remove the husk of the rice, reduce the burst of the rice and the damage of the surface skin, and keep the integrity of the brown rice as much as possible. The rice mill uses mechanical force to peel and whiten the brown rice. The rice huller and mill combined rice huller and mill are combined together to form the rice huller and mill combined rice huller with rice huller and mill functions.
Along with the increasing living standard of people, the requirements on grains are high. Different people have different whiteness requirements on rice, partial people like to whiten some rice, the traditional rice huller-mill combined rice machine is difficult to adjust the whiteness of the rice in continuous work, rice husking and whitening are directly discharged from a discharge port of the rice huller-mill combined rice machine, if the whiteness of the rice is to be increased, the whiteness of the rice is generally adjusted by repeatedly adding the whitened rice into the rice huller-mill combined rice machine or by adjusting the separation strength of husks, the rice milling strength and the like of the whole device, the operation is complex, and the consumed time is long. Therefore, gear rice mills with adjustable rice whiteness have been developed. The method controls the discharging time of the rice by adjusting the gap between the rice baffle and the discharging hole, and then controls the whiteness of the rice. However, when the existing rice mill adjusts the gear, when the pressure applied by a user unintentionally exceeds the pressure designed by the whole machine or the mechanical overload or dead halt caused by the voltage change of the power grid, the pressure relief pull rod on the hand wheel is required to be pulled for pressure relief, but the problem of unsmooth pulling and blocking generally exists.
Disclosure of Invention
The invention aims at: the gear regulator for the rice mill solves the problems of unsmooth pressure relief and Yi Kadu pressure relief of the gear regulator of the existing rice mill.
The technical scheme adopted by the invention is as follows:
The utility model provides a gear formula regulator for rice mill, which comprises a hand wheel, the release pull rod is installed to the hand wheel center, still overlap on the release pull rod and be equipped with screw pole and lower screw pole, the helicoid of going up the screw pole and the helicoid looks adaptation of screw pole down, go up the screw pole and be connected with the hand wheel, go up the screw pole and still overlap outward and establish and install the hand wheel seat, still overlap down the screw pole and be equipped with the guide ring, the guide ring is connected with the 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 the guide screw in the mounting hole, set up the bar groove with the guide screw looks adaptation on the lower screw pole, the release pull rod is kept away from hand wheel one end and is still installed the fender rice board, the cover is equipped with the fender rice board spring between guide ring and the fender rice board on the release pull rod.
Further, 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 on the pressure relief pull rod.
Further, 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 flower ring shape.
In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:
1. The invention comprises a hand wheel, wherein a pressure relief pull rod is arranged in the center of the hand wheel, an upper screw rod and a lower screw rod are 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 sleeved outside the upper screw rod, a guide ring is sleeved outside the lower screw rod, the guide ring is connected with the hand wheel seat, a mounting hole is further formed in the circumferential surface of the guide ring along the radial direction of the guide ring, a guide screw is arranged in the mounting hole, a strip-shaped groove matched with the guide screw is formed in the lower screw rod, a rice baffle plate is further arranged at one end of the pressure relief pull rod, far away from the hand wheel, and a rice baffle plate spring is sleeved between the guide ring and the rice baffle plate on the pressure relief pull rod.
Through this setting, the hand wheel right-hand rotation reaches the initial position, owing to the hand wheel is connected with last hob, and the hand wheel keeps synchronous rotation with last hob, keeps off rice leaf spring and reaches limit length this moment, is in pressureless state, goes up hob and lower hob and is in closely interlock state, becomes a cylinder. The gear is rotated anticlockwise, the spiral faces of the upper spiral rod and the lower spiral rod are extruded by stress to start spiral angle movement, at the moment, the lower spiral rod is stopped in a strip-shaped groove of the lower spiral rod by a guide screw on a guide ring, cannot rotate along with a hand wheel and can only do linear movement axially, the movement limit distance of the lower spiral rod is equal to the designed spiral lead, and in the movement limit distance, the gear number designed on the hand wheel equally divides the distance to form the gear. The linear distance of the lower screw rod motion 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 gear adjusting process is completed. When the pressure applied by a user unintentionally exceeds the pressure designed by the whole machine or the mechanical overload or dead halt caused by the voltage change of the power grid, the pressure release pull rod can be pulled to release the pressure by pulling the pull ring at the middle position of the handle wheel. The pressure relief pull rod is designed in the center of the hand wheel to relieve pressure, so that the problem that the same type of pressure relief pull rod is not smooth in pulling and is blocked due to the fact that the pressure relief pull rod is not arranged in the center is effectively solved. The multi-gear adjustment of the rice mill with the hand wheel within the range of 270 degrees is realized by a simpler structure and fewer elements.
2. In the invention, a spring guide plate is sleeved between a rice baffle spring and a guide ring on a pressure relief pull rod, and a spring positioning plate is sleeved between the rice baffle spring and the rice baffle on the pressure relief pull rod. Through this setting, when adjusting the gear, the straight line distance of lower hob motion acts on the spring deflector and again to the fender rice board spring and apply to the fender rice board again, makes down hob pressure move the process that keeps off rice board spring and makes the fender rice board displacement more stable, 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. By the arrangement, people can conveniently pull the pressure relief pull rod.
