Description

The automatic adjustable rice mill

Technical field

The utility model relates to Cereals Processing Machines equipment, belongs to the production technical field of miniature farm machinery, specifically a kind of automatic adjustable rice mill, and it is particularly suitable for peasant family and is used for paddy is carried out the husk rice operations.

Background technology

All be to be main production kind in the most agricultural district of China with rice cultivation, for broad masses of the people provide abundant edible rice, the rice that we eat with paddy through grind the system shelling, the rice bran sorting is processed into.High speed development along with China's agricultural machinery cause; At present; Farm machinery management department has worked out a series of policies and measures and has actively promoted the use of the family expenses rice mill, this to the amount of labour that alleviates peasant's husk rice operation, improve Mi Zhiliang and improve level of farming mechanization and all brought into play positive role.The existing rice mill that generally uses mainly is made up of several parts such as the host shell that feed hopper is installed, rice huller screen, rice milling roller and discharging governor motions; When carrying out the husk rice operation; Only need paddy is sent into the flow of controlling paddy in the rice mill and by the discharging governor motion by feed hopper; Starter motor drive rice milling roller to paddy grind the system shelling, again after chaff is removed in the rice huller screen sorting, can export the rice finished product by discharge bucket.But; Need not to dare not or would not speak up; We also recognize in actual production use for many years: the governor motion of existing rice mill exists degree of regulation low and regulation and control stability difference and the use defective of regulating troublesome poeration, being difficult to accurate grasp; Its reason is: the vibration that rice mill is produced when the husk rice operation also will directly influence the working stability performance of governor motion parts, can cause also when serious that stone roller pressing pressure in the host shell unusual fluctuations occur and then influences Mi Zhiliang.This is existing rice mill also needs further to improve and perfect place on structural design at governor motion, this also just the utility model want the further problem of solution.

The utility model content

The purpose of the utility model is intended to overcome the above-mentioned weak point that existing rice mill exists and proposes a kind of tooth plate structure of putting into gear that adopts and regulate the automatic adjustable rice mill of discharging gear.

The purpose of the utility model realizes by following technical scheme:

The automatic adjustable rice mill that the utility model proposes; It comprises host shell, be fitted to rice bran separating sieve in the host shell, be installed on the rice milling roller of main shaft; Said main shaft supporting is in front-end bearing pedestal and rear bearing block; It is characterized in that: the inner side end at rear bearing block is provided with the taper choma; On main shaft suit shift fork, spring with the taper choma mutually meter baffle plate that goes out of clutch constitute the automatic governor motion of discharging, on rear bearing block, be equipped with the suitable gear tooth plate of the action bars of putting into gear of shift fork and constitute discharging gear governor motion.

Say that further the utility model also has following technical characterictic:

Saidly go out a meter baffle plate and be installed on the slide, the spring-loaded that is set in main shaft is between slide and shift fork.

The design feature of the utility model is: it is that teeth groove by the put into gear action bars and the gear tooth plate of shift fork forms the structure of putting into gear and regulates the discharging gear; Can be according to the concrete working condition of actual operations; The action bars that only needs to put into gear is passed to selected teeth groove and can be regulated the discharging gear easily; The operation principle of the automatic governor motion of discharging is: passing put into gear action bars put into gear the operation in; The shift fork that is set in main shaft will be moved to the position of corresponding gear vertically; Be that shift fork capable of using is regulated setting spring to going out the precompression of meter baffle plate along the axial displacement of main shaft, when the husk rice operation, go out meter baffle plate and can dynamically respond to the open degree of grinding the variation of pressing pressure in the Continuous Tracking host shell and under the acting in conjunction of pre-pressure of the spring, regulating the taper choma automatically; Make the stone roller pressing pressure in the host shell remain at best steady-working state, can realize that accuracy controlling goes out Mi Liuliang and guarantees the stay-in-grade goal of the invention of rice.Because the utility model is to adopt optimizing structure that tooth plate puts into gear to realize regulating the discharging gear, can improve the stability against earthquake performance of governor motion effectively.The utility model uses through actual motion and shows: it has, and the adjusting gear is easy to operate, the gear of putting into gear stable, degree of regulation is high, the good outstanding advantage of regulation and control stability, can thoroughly prevent to regulate the phenomenon that parts generation displacement influences Mi Zhiliang because of the main frame vibration makes.

The utility model compared with prior art has following substantive distinguishing features and progress:

The utility model has been initiated the discharging gear governor motion of " put into gear action bars and the adaptive formation of gear tooth plate put into gear structure " on rice mill; Can use meter baffle plate is regulated the taper choma automatically under the effect of grinding pressing pressure and pre-pressure of the spring open degree; But accuracy controlling goes out Mi Liuliang, obviously improves and Mi Zhiliang, it has, and structure is simple and direct, production cost is low, easy to install, the gear shift operation is easy to grasp, the regulation and control stability is strong and go out the measured advantage of meter matter.
