Abstract

The utility model relates to a sieve plate as a main part used in a rice processing machine, in particular to a multifunctional sieve plate capable of finishing rice husking, husked rice polishing and rice-bran separation in one step. The multifunctional sieve plate is arranged in a rice machine and comprises a sieve surface for bearing materials and sieve meshes uniformly distributed in the sieve surface and used for separating bran husks, wherein husk scraping knives for husking the materials are arranged at the horizontal gaps of the sieve meshes in the front charge hole end of the sieve plate; convex points for polishing the husked materials are formed in the horizontal gaps of the sieve meshes in the rear charge hole end of the sieve plate; and the husk scraping knives and the convex points are all arranged on the sieve surface of the sieve plate in contact with the materials. According to the multifunctional sieve plate, three husk scraping knives are added in only the production of the original sieve plate, a certain amount of the convex points are stamped on the original sieve plate, the production cost is low, the process is simple, but multiple functions can be achieved, and the production efficiency is improved by more than 40%, so that the multifunctional sieve plate is energy-saving and practical.

Description

A kind of multi-functional sieve plate

Technical field

The utility model relates to the critical piece sieve plate that uses in the rice processing equipment, refers in particular to the multi-functional sieve plate that the polishing of the disposable completion paddy husking of a kind of ability, brown rice separates with rice bran.

Background technology

In the rice processing factory, earlier paddy is shelled with shelling machine in modern times, isolate brown rice with grain separating machine again, after brown rice being polished with polishing machine, separate into rice through rice bran again, this process must cooperate through each Xingqi duty of many machineries to be accomplished.But rural area in some remote mountain areas of China; The peasant can not send to processing factory far away from the grain ration of eating, the processing of can only being in, and small-sized rice machine has become unique instrument of their paddy processing; And small-sized rice machine is limited by the type body; Generally can only accomplish paddy husking, rice bran separation, the rice matter that therefore processes is bad, can only gather together edible.Therefore, how to let the millet machine in shelling, separate in the function of tool polishing again, this is a very big difficult problem.

Summary of the invention

The purpose of the utility model is to improve and innovate to defective that exists in the background technology and problem, provides a kind of under the situation that does not change other parts of millet machine, produces the multi-functional sieve plate that rice is polished in the high-quality shelling.

The technical scheme of the utility model is a kind of being arranged in meter machine of structure, separates the sieve aperture of chaff shell on comprising the compass screen surface that carries material and being distributed on compass screen surface, wherein:

The sieve aperture lateral clearance place of feed inlet end is provided with to what material shelled and scrapes the shell cutter before the sieve plate, and the sieve aperture lateral clearance place of discharge port end is provided with to the salient point of back material polishing that shells behind the sieve plate, and scrapes shell cutter and salient point and all be located on sieve plate and the compass screen surface that material contacts.

Advantage of the utility model and beneficial effect:

The utility model only adds that three are scraped the shell cutter when former sieve plate is produced, and the salient point of some in the punching press, and production cost is not high, and technology is simple, but can realize a tractor serves several purposes, enhances productivity more than 40% energy-conservation practicality.

Description of drawings

Fig. 1 is the utility model polygonal screen plate structure sketch map.

Fig. 2 is the semicircle sieve-plate structure sketch map of the utility model.

The specific embodiment

Can know that by Fig. 1,2 the utility model is arranged in meter machine, separate the sieve aperture 2 of chaff shell on comprising the compass screen surface 1 that carries material and being distributed on compass screen surface 1, wherein:

The sieve aperture 2 lateral clearance places of feed inlet end are provided with to what material shelled and scrape shell cutter 3 before the sieve plate; The sieve aperture 2 lateral clearance places of discharge port end are provided with to the salient point 4 of back material polishing that shells behind the sieve plate, and scrape shell cutter 3 and salient point 4 and all be located on sieve plate and the compass screen surface that material contacts.

The described salient point 4 of the utility model raises up, and is arranged in uniformly in the gap of the per two row's sieve apertures 2 in sieve plate rear end.Describedly scrape shell cutter 3 welding or through being bolted to each compass screen surface 1 front end, and at least two of every sieve plate settings.The described shell cutter 3 of scraping is the strip that high rigidity, strong high-abrasive material are processed, and thickness is less than the diameter of processing materials grain.The strip through-hole of described sieve aperture 2 for being obliquely installed, and incline direction is consistent with rice machine screw propulsion direction, leaks down for preventing the processing materials grain, and the width of sieve aperture 2 is less than the diameter of processing materials grain.Said sieve plate is semicircle sieve plate, perhaps is the polygon sieve plate.

Structure of the utility model and operation principle:

The utility model is on the sieve plate of millet machine, and the paddy feeding port front end adds scrapes the shell cutter more than three, and this cutter thickness can not require high rigidity, wear-resisting by force greater than the grain diameter, and available sunk screw or spot welding are fixed on the sieve plate; The sieve plate rear end rushes to the dot on the compass screen surface that is distributed on that raises up when dashing leakage chaff hole.

When the utility model used, grain was in charging aperture entering machine, under the iron roll of band screw propulsion on the rice machine main shaft drives; Rapidly rotation is advanced; Because having increased by three scrapes the shell cutter, become chaff from leaking chaff sieve aperture venting so soon rice hulls is scraped off, scrape the brown rice that shells and advance to the machine sieve place that is covered with salient point; The polished chaff skin that goes under the friction extruding of iron roll and salient point waits from discharging opening to come out to have become sparkling and crystal-clear white bright rice.

The described embodiment of the utility model only is the description that the preferred implementation of the utility model is carried out; Be not that the utility model design and scope are limited; Under the prerequisite that does not break away from the utility model design philosophy, engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
