Abstract

The utility model relates to a pneumatic screening machine, which can screen and separate grains (wheat) and grain chaff by taking advantage of pneumatic force generated in a mechanical way. The purpose of the utility model is that the grain chaff, long slag, soil particles, and grain coat guests are automatically separated by constantand concentrated pneumatic quantity. The main structure is that a crank shaft 13 is rotated by a motor 1 which is positioned on a machine frame 6 through a pulley wheel, and the up and down movement of a movable support frame 11 and the side-to-side movement of a basket component are respectively driven by two sets of connecting rod mechanisms which are positioned on the crank shaft 13. A hermetic pneumatic box body is composed of a left and a right side plates 8, a front top plate 9, and an air duct plate 3; the lower part is provided with a font and a back funnels 5 and 4. The utility model has the advantages that the work efficiency is more than 1500 kilograms /hour, and the effect of separating and removing can be more than 98 percents which is more than 30 times than artificial sound amplification.

Description

Wind screening machine

The utility model relates to and utilizes machinery to produce wind-force, and paddy (wheat) grain and paddy (wheat) chaff are carried out the machine of separation screening, specially refers to a kind of wind screening machine.

In background technology, be example with the wheat, present vast rural area uses three kinds of methods to winnow: one is to use fan to winnow, the method weak point is that wind-force is difficult for concentrating use, meet faint natural wind, its air channel also can become mixed and disorderly and can't work, and exposed fan is absolutely unsafe again.Two are to use windmill, this windmill, and wind-force is little, and long slag can not separate, and seed of not peeling (being commonly called as wheat skin visitor) and grogs can not be removed, and efficient is low.The 3rd, most of people still adopt ancient traditional approach, and promptly natural wind is winnowed, and natural wind not only needs to wait bitterly for, and needs the cooperation of wind direction, wind-force and the time of natural wind again, and so inconvenience and uncontrollable factor are worked people round the clock, and are arduous unusual.

The purpose of this utility model is the weak point that solves in above-mentioned each method, develops a kind of wind screening machine, and it is constant and can concentrate use to reach air quantity, can separate cavings, long slag, grogs automatically and reach " wheat skin visitor ", raise the efficiency, and the screening purpose of practicality again.

The former technical solution of the utility model is as follows:

Comprise that motor 1 output shaft on the frame 6 connects belt pulley 22 down through driving-belt, assembling fan blade assembly 2 on the following belt pulley 22, it is characterized in that: following belt pulley 22 connects upper belt pulley 21 through driving-belt, floral disc 20 is assemblied on the upper belt pulley 21, floral disc 20 is through transmission chain belt connecting crank axle 13, two groups of linkages of assembling on the crank axle 13, one group connects the square-bottomed bamboo basket assembly 10 that can swing, another group connects the support alive 11 that can move up and down, assembling is by a left side on the frame 6, right plate 8, front top plate 9, exit plate 7, the plate 3 common airtight wind box of forming in air channel are before the wind box,

funnel

5 and 4 before and after the assembling on the frame 6 of below, middle part.

Technical solution of the present utility model also comprises:

In two groups of linkages that assemble on the crank axle 13, one suite arbor 13 is through crank 17, connecting rod 18, the rocking bar 19 hinged square-bottomed bamboo basket assemblies 10 that seesaw, another suite arbor 13 connects the support 11 of living through crank 16, connecting rod 15, rocking bar 14, and support 11 middle parts of living are hinged on the boxhole place on frame 6 tops.

In above-mentioned airtight bellows, air channel plate 3 upper and lower plates be combined into inclination into and out of the air port, upper plate is relative in front top plate 9 and the air channel plate 3 misplaces, preceding high back is low, square-bottomed bamboo basket assembly 10 in the swing is low early and high after, and height is by low gradually high between the front and

back funnel

5 and 4 of bellows below.

The boxhole place of support 11 alive is equipped with the adjusting device 12 of adjustable boxhole size on frame 6 tops, be assemblied on the two little axles by the two boards correspondence that can dig, two same ends of little axle connect driving lever separately, connect the connecting rod of adjustable two boards mouth size between the driving lever, and a little axle head connects handle.

Accompanying drawing of the present utility model is the complete machine structure schematic diagram, and number in the figure is described as follows:

1-motor, 2-be with the leaf assembly, 3-air channel plate, funnel behind the 4-, funnel before the 5-, 6-frame, 7-exit plate, the left and right side plate of 8-, the 9-front top plate, 10-square-bottomed bamboo basket assembly, 11-support alive, 12-boxhole size adjustment device, the 13-crank axle, 14-rocking bar, 15-connecting rod, 16-crank, the 17-crank, 18-connecting rod, 19-rocking bar, the 20-floral disc, 21-upper belt pulley, belt pulley under the 22-.

The utility model embodiment is as follows: referring to accompanying drawing, the 6 right end of frame motor 1 connects belt pulley 22 down through driving belt, assembling fan blade assembly 2 on the following belt pulley 22, assemble driving belt between the

belt pulley

21 and 22 up and down, upper belt pulley 21 borders are floral disc 20 fixedly, floral disc 20 is through chain belt (or other driving-belt) connecting crank axle 13, two groups of linkages of assembling on the crank axle 13, wherein one group by crank 17, connecting rod 18, rocking bar 19 is formed, the hinged square-bottomed bamboo basket assembly 10 that swings of rocking bar 19 1 ends, square-bottomed bamboo basket assembly 10 in the motion is low early and high after, and this is one of characteristics of the present utility model.Another group is made up of crank 16, connecting rod 15, rocking bar 14, and rocking bar 14 1 ends connect the support 11 of living, and support 11 middle parts of living are hinged on frame 6, and it is reciprocal up and down that the front and back washboard is, those high these low corresponding motions, and this is two of the utility model characteristics.Airtight wind box is made up of left side plate 8, front top plate 9, exit plate 7 and air channel plate 3, and this is three of a design feature, front top plate 9 and relative dislocation of air channel plate 3 upper plates, and preceding high back is low, and height is by low gradually high between the front and

back funnel

5 and 4 of wind box below.Back funnel 4, square-bottomed bamboo basket assembly 10 and boxhole place support 11 upper-lower position correspondences alive.When cereal when boxhole drops into, support 11 does not stop to pump because of living, regardless of different kinds of, length cereal, all enter square-bottomed bamboo basket assembly 10 very soon, because screen cloth all is equipped with in group and bottom behind the square-bottomed bamboo basket in the square-bottomed bamboo basket assembly 10, make long slag and cavings be blown out outside the machine, and " wheat skin visitor " and big grogs fall into preceding funnel 5 from the square-bottomed bamboo basket mouth, need treat to peel again, paddy (wheat) grain enters back funnel 4 with grogs, and grogs leaks down through screen cloth, and grain separates, the purpose that realization is once cleaned, whole screening process can be carried out continuously.

Advantage of the present utility model and effect are as follows:

1. whole screening is to carry out in machine, can automatically separate paddy (wheat) grain and paddy (wheat) chaff, Automatically remove long slag, cavings, " wheat skin visitor " and grogs through the field operation test, are removed effect and can be reached 98% More than, be more than 30 times that manually winnows.

2. air quantity foot, wind-force is constant and concentrated, operating personnel are easy to control, and not disturbed by extraneous wind direction or Impact, through performance testing, the wind power utilization rate is high, and screening rate per hour can be cleaned more than the 1500kg.

3. this machine is in light weight, and about 54 kilograms, economize the energy, adopt 110 watts motor; Use occasion is not subjected to Safety, reliable is used in restriction, is the powerful of operation on summer, the autumn field.
