The utility model is characterized in that some eccentric wheel assemblies are arranged on the vertical bar which receive power, eccentric wheel assemblies are connected with the sieve by punchers, rolling bearings are arranged under the end part of the sieve on the both sides, the outlet of peanut kernels and the shaking swing arm which is live connected with the sieve is arrange on the forepart of the sieve. The conception and design of the utility model is novel and scientific. The utility model has the advantage that reducing the links of power transmission, save labor, time, man-power and manufacture cost, easy to make, improve work efficiency 5 to 8 times and has long working life, therefore provides high value in using and generalization.

Description

Shelled peanut sizing screening machine

Affiliated technical field

The utility model relates to a kind of screening machine, relates to a kind of shelled peanut sizing screening machine specifically, belongs to the agricultural machinery technical field, mainly is adapted to the shelled peanut sizing screening and uses.

Background technology

At present, known its structure of shelled peanut screening machine be by framework, feed hopper, sieving and grading sieve with and on classification peanut kernel outlet and swing rocking arm, the outlet of not plump benevolence impurity, be connected the rolling bearing of classifying screen and the transfer device of track and power connects and composes.When power input transmission device, drive sprocket fixedly connected on the framework is given double-deck pull rod by chain with transmission of power, connects the parallel again and again reciprocating swing of double-deck pull rod that classifying screen jigs rear wall, in the hope of reaching the purpose of sizing screening.But, adopt sprocket wheel and chain to carry out transmission of power by double-deck pull rod, make and the mounting process complexity, the waste raw material, the cost height, also chain is not wear-resisting, often damages and changes, be also must add a lubricating arrangement or hand oiling to lubricate again, trouble is inconvenient, so production efficiency is low, take a lot of work, time-consuming, require great effort, the demand of very inapplicable production does not reach the purpose of efficient rapid classification screening.

Summary of the invention

In order to overcome above-mentioned drawback and defective, the utility model provides a kind of shelled peanut sizing screening machine, this not only fabrication and installation save time conveniently, operate steadily, the more important thing is the complicated link of having cancelled sprocket wheel and chain drive, so sturdy and durable, convenience easy to maintenance, high efficiency.

The technical scheme that its technical problem that solves the utility model adopts is: its structure of the utility model comprises framework, classifying screen jigs, the swing rocking arm, the classification peanut kernel outlet, rolling bearing, track, the outlet of not plump benevolence impurity be connected the vertical single pole driver etc. that classifying screen jigs rear wall, described vertical single pole driver connects driven pulley on the vertical big bar by the driving wheel on the motor through belt, the driven pulley that is fixed on the vertical big bar is given vertical big bar with transmission of power, multilayer eccentric wheel assembly is installed on the vertical big bar, be evenly distributed on the eccentric wheel assembly on the vertical big bar, circle is one to be fixed on the eccentric wheel on the vertical big bar in it, the fixedly connected bearing inner race of eccentric wheel periphery, in the bearing, accompany rolling element between the outer ring, bearing outer ring is fixed on the eccentric wheel housing, the eccentric wheel housing is fixedly connected on the single entry push rod, the work of single entry push rod is connected in classifying screen and jigs rear wall, the rolling bearing on the track on the framework of being fixed on that classifying screen jigs lower end, two side, rear portion is fixed on classifying screen by transverse axis and jigs the bottom, rear end, classifying screen jigs the front portion has one to be fixed on the swing rocking arm that moves back and forth on the framework, it is the classification peanut kernel outlet that its classifying screen jigs the front end bottom, a not plump benevolence is arranged below its last classification screening sieve rear portion, the impurity outlet.When starting operation procedure, power is passed to driven pulley through driving wheel, driven pulley drives vertical big bar rotation, to the greatest extent and the rotation of the multilayer eccentric wheel on the vertical big bar, eccentric wheel drives the rolling element rotation on the bearing inner race, because eccentric moment does not wait, the centrifugal force that rotation is produced is also unequal, according to this principle, the eccentric wheel housing that is fixed as one with bearing outer ring just produces a kind of step motion rail journey that swings back and forth that comes and goes, the power that rotation is produced becomes linear uniform motion through the conversion of intermediate link, and the single entry push rod that connects the eccentric wheel housing is pushing away classifying screen and jigging by the linear slide at the uniform velocity back and forth of the rolling bearing on the track.So far, realized the purpose of invention.

The beneficial effects of the utility model are: reduced the complicated link that intermediate power is transmitted, it is very convenient to operate, and production process is simple, saves material, cost reduces greatly, and wear-resistant, long service life, the more preceding raising of operating efficiency 5-8 is doubly, higher value for applications is arranged, through update search, do not find as yet at present state, inside and outside have identical or the similar techniques feature, so common mechanical producer needn't increase the production of can practicing midwifery or change the line of production of any facility.
