Abstract

An adjustable stem bend screening device relates to tobacco processing equipment, is effective in use and capable of realizing reduction of cleaning and maintaining labor intensity and prolonging of the service life. The adjustable stem bend screening device is provided with a tank, an upper screening bar layer, an upper screening bar support, a lower screening bar layer and a lower screening bar support, wherein the upper screening bars are fixed on the upper screening bar support, the lower screening bars are fixed on the lower screening bar support, the upper screening bar support and the lower screening bar are fixedly staggered, one of the upper screening bar layer and the lower screening bar layer is directly fixed on two side boards of the tan, the other one of the upper screening bar layer and the lower screening bar layer are fixed by the two side boards of the tank and can be lifted and lowered, initial positions of upper secondary screening bars and lower secondary screening bars are subject to the position of an equilateral triangle sectionally formed by optional one of the upper secondary screening bar and two lower screening bars adjacent to the optional upper secondary screening bar, and an elongated leaking slot is formed between each two adjacent screening bars.

Description

A kind of adjustable stalk turns a screening plant

Technical field

The utility model relates to a kind of tobacco processing equipment, especially relates to a kind of efficient adjustable stalk and turns a screening plant.

Background technology

At the threshing and redrying production line of tobacco processing, the offal after the stalk leaf separates, some is to be with the stalk of knob to turn head, its dense structure, xylon gas is highly seasoned, is the discarded object of cigarette enterprise, must from offal, sieve rejecting.Existing screening is rejected technology and is generally accomplished by a kind of vibration screening device.Chinese patent ZL 200920137084.8 discloses the adjustable offal head of a kind of spacing screening plant, and it comprises screening bar, the groove that shakes, and also comprises screw mandrel support, adjusting nut, spring shim, sieve bar locating piece; The screw mandrel spacer support frame is staggered to be provided with the sieve bar locating piece and the spring shim that can wear location screening bar and to form horizontally-arranged, and horizontally-arranged two ends spring shim is provided with packing ring and adjusting nut, regulates the screening distance between tie rods with adjusting nut; The screw mandrel support that is provided with screening bar, sieve bar locating piece, spring shim, adjusting nut is built in the cell body; Shaking, both sides respectively are provided with a sloping baffle above the groove; Form a bar shaped and leak the material mouth; Carry offal head above the screening bar, carry offal below less than the screening distance between tie rods greater than the screening distance between tie rods; When needing the adjustment spacing, through regulating adjusting nut, change clamping force, utilize the elastic force return of spring shim, it is adjustable to form the screening distance between tie rods.The weak point of this screening plant is that the adjustable range of spacing is little, can influence screening effect; Simultaneously in actual use since stalk to turn the head heavy-tailed light, center of gravity substantial deviation geometric center can erect on the screening bar and is clipped between the screening bar, causes cleaning inconvenience and influences screening effect.

Summary of the invention

The purpose of the utility model is to provide a kind of result of use better, can reduce cleaning and safeguard labour intensity, and the adjustable stalk that prolongs screening plant service life turns a screening plant.

The utility model is provided with cell body, upper strata screening bar, upper strata screening shaft bar, lower floor's screening bar and lower floor's screening shaft bar; Said upper strata screening bar is fixed on the upper strata screening shaft bar, and lower floor's screening bar is fixed on lower floor's screening shaft bar, and upper strata screening shaft bar and lower floor's screening shaft bar are staggered fixing; Wherein one deck of upper strata screening bar and lower floor's screening bar directly is fixed on the biside plate of cell body; Screening bar in upper strata is fixing and adjustable up and down through the cell body biside plate with another layer of lower floor's screening bar, and the initial position of upper strata screening bar and lower floor screening bar is that any upper strata is sieved bar and adjacent two lower floors and sieved bar forms equilateral triangle on cross section position and be as the criterion; Spacing between adjacent two screening bars forms strip and leaks hopper.

Said upper strata screening bar preferably vertically evenly distributes and is fixed on the upper strata screening shaft bar.

The utility model provides a kind of screening plant and its spacing control method in order to solve weak point of the prior art, to solve the spacing adjustment and to turn the problem that head uprightly influences the screening plant result of use because of stalk.

The utility model is according to the characteristic of the three-way unification of isosceles triangle, i.e. the characteristic of the height on the center line on drift angle bisector, base and base coincidence through changing the height on isosceles triangle base, changes stringcourse length, to reach the purpose of regulating the screening spacing.

The beneficial effect of the utility model is mainly reflected in result of use, and the one, easy to adjust reliable, the 2nd, stalk turns head and is not sandwiched between the screening bar, cleans unobstructedly between the screening bar all the time, reduces cleaning and safeguards labour intensity, helps guaranteeing screening effect.

Description of drawings

Fig. 1 is that the structure of the utility model embodiment is formed sketch map.

The specific embodiment

Referring to Fig. 1, the utility model embodiment is provided with cell body 1, upper strata screening bar 2, upper strata screening shaft bar 3, lower floor's screening bar 4 and lower floor's screening shaft bar 5; Said upper strata screening bar 2 is fixed on the upper strata screening shaft bar 3, and lower floor's screening bar 4 is fixed on lower floor's screening shaft bar 5, and upper strata screening shaft bar and lower floor's screening shaft bar are staggered fixing; Wherein one deck of upper strata screening bar and lower floor's screening bar directly is fixed on the biside plate of cell body 1; Screening bar in upper strata is fixing and adjustable up and down through cell body 1 biside plate with another layer of lower floor's screening bar, and the initial position of upper strata screening bar and lower floor screening bar is that any upper strata is sieved bar and adjacent two lower floors and sieved bar forms equilateral triangle on cross section position and be as the criterion; Spacing B between adjacent two screening bars forms strip and leaks hopper.

The basic structure of the utility model adopts the structure of shell fragment bobbing machine, and the design of compass screen surface comprises screening bar and support, divides two-layer.Upper strata screening bar is fixed on the upper strata screening shaft bar, and lower floor's screening bar is fixed on lower floor's screening shaft bar, and the screening bar vertically evenly is fixed on the support by a determining deviation; Levels screening shaft bar is staggered fixing; Wherein one deck of two-layer up and down screening bar directly is fixed on the biside plate of cell body 1; Another layer also is to fix through cell body 1 biside plate; But adjustable up and down, its initial position sieves bar forms equilateral triangle on cross section position and is as the criterion to guarantee any upper strata screening bar and adjacent two lower floors; Spacing B between adjacent two screening bars forms strip and leaks hopper.During work, after offal falls into upper strata screening bar, turn head greater than the stalk of screening distance between tie rods B and stay on the compass screen surface, after screening, drop in the cell body 1 and be transferred away less than the offal of screening spacing B.During adjustment, unclamp the fastening bolt of that adjustable one deck screening bar cell body 1 biside plate, spacing H is to meeting the demands, and fastening bolt gets final product then.

In Fig. 1, B representes to sieve the horizontal center distance between the bar, and H representes the vertical centre distance between the levels screening bar.
