Abstract

The utility model discloses a movable oscillating grain-screening machine, belonging to the separated and sorting equipment form solids to solids. The utility model is particularly is suitable for the screening of the grain particulates. The vibration generated by a motor driving an eccentric motion component drive an upper screen body to vibrate through an eccentric link and also drive a lower screen body to vibrate through a mechanical connection frame on a frame. Four pairs of spacer springs isolates the vibration in the upper screen body and the lower screen body and does not transfer to a bottom frame and a caster wheel which can be used as a movable grain-screening machine.

Description

Movable oscillating grain-screening machine

The utility model (design) packaged type vibratory sieve grain machine belongs to solid is separated from solid, and screening installation is specially adapted to the screening of grain.

Existing sieve grain equipment great majority are fixed vibratory sieve or easy stream sieve, fixed vibratory sieve must be fixed on the eccentric motion parts that cause vibration on the ground to support sieve vibration up and down, Gu this, fixed floor space is big, and benzene is heavy, the mounting cost height, inconvenient operation, can only be used in the workshop or the grain that after screening, directly puts in storage screening, can not be at Ku Yuan, the warehouse district mobile operational process.The stream sieve is used for middle-size and small-size grain depot or storage department mostly, because cool solarization area is wide, mobile big, the stream sieve can be with placing the sieve end on the framework of angle steel connection, prop the screening of flowing naturally by particle of angle that one side forms with it, thereby the flow that grades sifts out up entirely, screening purity is low, grain foreign material after the screening are many, influence grain quality.

The design's purpose is the above-mentioned shortcoming that overcomes fixing vibratory sieve and stream sieve, a kind ofly both can be moved the or not packaged type vibratory sieve of sieve grain machine integral body when bolting work by four castors by well-designed producing.

The screening that employing the design's product can solve storehouse institute mobile operational process and stored grain, thus convenient the use reduced the grain impurity content.

The big feature that the design sieves the grain machine is to be driven by eccentric ratio by the vibration one side that driven by motor eccentric motion parts cause to go up the sieve nest vibration, and the support with motor and eccentric motion parts causes down the sieve nest vibration by mechanical connection frame and following sieve nest connection on the other hand; Four pairs of spacer springs are isolated in sieve nest zone up and down with vibration, do not pass to underframe and castor.And when operation is changed places in transfer, can draw the castor place of being assigned a new job.Because its deft design, floor space is little, is convenient to move, and has solved the demand of mobile operational process such as storehouse institute storage.

Fig. 1 is the design's a perspective view.

Fig. 2 is the design's a detailed connection schematic diagram.

1 for going into the grain bucket among the figure, and 2 is last sieve nest, and 3 are sieve No. 1, the end, 4 is motor, 5 is the eccentric motion parts, and 6 is eccentric ratio, and 7 is the mechanical connection frame, 8 is a pair of spring, 9 is the slag notch of last sieve nest, and 10 are following sieve nest, and 11 are No. 2, the sieve end, 12 are sieve No. 3, the end, 13 are sieve nest finished product of grain outlet down, and 14 are the rejected grain outlet, and 15 are the dust outlet, 16 is a pair of spacer spring, 17 is underframe, and 18 is four castors, and 19 is a pair of spacer spring between motor and eccentric motion body support frame and the last sieve nest, 20 be with another of 16 symmetries to spacer spring, 21 is the support of motor and eccentric motion parts.

Existing conjunction with figs. is described below the design's embodiment:

The last sieve nest 2 of square groove shape with go into grain bucket 1 and be welded into one, put out cereal mouthfuls 9 on the last sieve nest 2, following sieve nest 10 is connected with last sieve nest so that upward the sieving of sieve nest 2 flows directly into down sieve nest, sieve nest junction outer rim is equipped with a pair of spring 8 up and down, motor 4 and eccentric motion parts 5 are contained on its support 21, the connecting rod 6 of eccentric vibrating mass 5 by being connected with last sieve nest 2, cause sieve nest 2 and go into 1 vibration of grain bucket, go into a pair of shock-absorbing spring 19 is housed on the column between grain bucket 1 and last sieve nest 2 and the support 21, eccentric motion parts 5 directly pass to down vibration sieve nest 10 and make its vibration by the mechanical connection frame 7 that is connected with its support 21 and be welded in down the sieve nest outside, complete machine underframe 17 and the position of following sieve nest more than 10 are by the spring 16 on two columns, 20 are isolated in two sieve nest zones with vibration, do not pass to underframe and be contained in four castors 18 below the underframe, last sieve nest 2 and following sieve nest 10 inside are equipped with screw and are fixed on the angle iron frame at the bottom of the removable sieve No. 13, the sieve end No. 2 11 and the sieve end No. 3 12, finished product of grain outlet 13 is arranged at following sieve nest 10 bottoms, rejected grain outlet 14 and dust outlet 15, when going into the grain bucket is that 1000mm is wide, last sieve nest is that 1000mm is wide, following sieve nest is that 1050mm is when wide, two sieve nest per minutes vibration 840 times, eccentric throw is 3, per hour can sieve 40 tons in grain.

It is rational in infrastructure, novel that the design sieves the grain machine, and floor space is little, and the activity convenient transfer can be according to user's needs design size.Use this vibration screen capacity to improve 4 times, and owing to have at the bottom of 3 sieves that can change according to the grain kind, make the grain that the sifts out purity of grading improve 4-6 doubly, use the classification of this sieve grain machine grain to know and to tell big slag, finished product of grain, rejected grain and dust than stream sieve.
