Abstract
The utility model relates to a rice processing mechanism, in particular to a cribriform plate for rice stone-removing machines. A plurality of apertured bosses are evenly distributed on the surface of the cribriform plate, the back surfaces of the bosses are rectangular concaves with circular arcs on both sides. The long side of the rectangular concave stretches outward, forming an apertured front facade and a back bevel with circular ends. The utility model is an alternative to the conventional rice stone-removing method which features in a procedure consisting of manual selection, wind selection, round hole sieve classifying and rice washing by means of floatation force of the water, wherein uniform staggered bosses with arc inclined surfaces are punched on the steel plates, small lengthwise holes are clipped on the front vertical surfaces of the boss facing the direction thereof. By utilization of the vibration produced by a motor, stones, sand, other matters are thoroughly separated and brought to more than two different outlets respectively due to different weights of the grains and sands. The utility model is economical, energy-saving and practical.
Description
Technical field
The utility model relates to the rice organisation of working, refers in particular to rice stone remover sieve plate.
Background technology
In the paddy of peasant's results,, make unavoidably and be mixed with some sand grains, stone in the paddy because harvest machinery splashes earth and the airing process is sneaked into silt.Conventional practice adds utilizes selection by winnowing, round-hole mesh sorting man-hour, but because the sandstone grain varies in size, and often also difficulty is clean with the sandstone choosing through tens sortings, causes and is with sand in the rice, has a meal and presses against tooth, the consumer is difficult to accept.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provides a kind of technology advanced person, with low cost, practical especially rice to remove the stone sieve plate.
The realization the technical solution of the utility model is: evenly be staggered on the sieve plate matrix surface boss in crack with holes of the utility model, the back side of boss is the rectangle concave surface of two ends band circular arc, and the length direction of boss projection and the preceding facade that forms crack with holes become the back bevel of circular arc with two ends.
The utility model changes picking, selection by winnowing, the round-hole mesh classification choosing of former rice processing shakeout stone employing and utilizes the old way of buoyancy of water sorting when rice washing, the little slotted hole that facade cuts simultaneously towards boss before the even staggered circular arc of utilization punching press on steel plate inclined-plane boss and the boss, under the vibration force effect that the frame vibration motor produces, utilize grain different with the gravity of sandstone, and on frame the discharging opening of two above diverse locations, separate various sandstones, foreign material, once thoroughly separate through this sieve plate, economical, energy-conservation, practical.

The specific embodiment
By Fig. 1 to 5 as can be known, the utility model is at evenly the be staggered boss (2) of crack with holes (5) of sieve plate (1) matrix surface, the back side of boss (2) is the rectangle concave surface of two ends band circular arc, and the length direction of boss (2) projection and the preceding facade (4) that forms crack with holes (5) become the back bevel (3) of circular arc with two ends.
The preceding facade of boss described in the utility model (2) (4) is cut off when punching press and is formed a strip hole (5), and forms the back bevel (3) of a band circular arc through punching stretch.The utility model has thoroughly changed the traditional approach of former material shakeout stone, sandstone thoroughly can be separated, and saving of labor, energy-conservation enhances productivity tens times.
Claims (2)
1. an efficient rice removes the stone sieve plate, it is characterized in that evenly the be staggered boss (2) of crack with holes (5) of sieve plate (1) matrix surface, the back side of boss (2) is the rectangle concave surface of two ends band circular arc, and the length direction of boss (2) projection and the preceding facade (4) that forms crack with holes (5) become the back bevel (3) of circular arc with two ends.
2. efficient rice according to claim 1 removes the stone sieve plate, it is characterized in that the preceding facade of described boss (2) (4) is cut off to form a strip hole (5) when punching press, and forms the back bevel (3) of a band circular arc through punching stretch.
