Description

The gently assorted winnowing machine of grain

Technical field

The invention belongs to the grain machinery field, particularly relate to a kind of gently assorted winnowing machine of grain that can from the material of graininess grain such as paddy, wheat, isolate light impurity.

Background technology

At present, the clear general labourer's tool of the grain that use in the rural area mostly also is manual machine, and its shortcoming is that labour intensity is big, and production efficiency is low, and assorted clearly weak effect.In the prior art be: 200820008376.7 exhausting formula multifunctional grain winnowing machine as China Patent No., use manual machine labour intensity big though solved the rural area, shortcomings such as production efficiency is low, but because its selection by winnowing mode all is to adopt air draught type, it also is a side that just blower fan is installed in wind sucting tube, adopt material swash of wave mode to separate through the air port, there is following shortcoming in this type of winnowing machine that adopts air draught type to carry out selection by winnowing: the material that (1) blower fan the separates impact velocity of getting off is too fast, light assorted being followed by material easily subdued, the blanking skewness, inferior separating effect, thus the storage standard that all will just can reach national regulation when processing grain made through the processing more than two roads; (2) its maximum shortcoming is that treating capacity is very low, if want to increase treating capacity, will strengthen the air quantity of blower fan and the width of machine, not only cause machines cumbersome, and the blower fan electrical loss is big, and machine manufacturing cost height is not suitable for rural area landlord's use; (3) in addition the selection by winnowing mode adopts air draught type, and is can not wind recycling, causes pollution of peripheral dust or the like.

Summary of the invention

The objective of the invention is shortcoming at the gently assorted winnowing machine existence of above grain of the prior art, and provide design a kind ofly can overcome the defective that the selection by winnowing mode adopts air draught type, thereby reach good separating effect, energy-efficient, cost is low, the gently assorted winnowing machine of light a kind of grain handy, no dust pollution.

A kind of grain of the present invention gently technical scheme of assorted winnowing machine is: the gently assorted winnowing machine of a kind of grain, mainly constitute by frame 3, motor 8, impeller 6, the assorted separation chamber of grain, hopper 10 etc., it is characterized in that: the assorted separation chamber of grain is designed to be fixedly mounted on the drum of the assorted cylinder 19 of grain of the top of frame 3, and hopper 10 is contained on the top center position of the assorted cylinder 19 of grain; Be provided with a Blowing drum 14 in the assorted cylinder 19 of grain, the 14 upper and lower ends of Blowing drum, be made as port; Impeller 6 is housed below motor 8, a decelerator 9 is installed above motor 8, above decelerator 9, be connected with an equal charging tray 12 of rotation, rotate equal charging tray 12, decelerator 9, motor 8 and impeller 6 and fuse and adopt fixed support 13 uprightly to be installed in the centre in Blowing drum 14 intervals; Rotate the discharging opening that top that equal charging tray 12 is positioned at Blowing drum 14 upper port faces hopper 10; Between the barrel shell of the barrel shell of Blowing drum 14 and the assorted cylinder 19 of grain, be separated with one deck interlayer board 15, with the assorted Disengagement zone of grain of the assorted cylinder 19 of grain between be separated into clean grain interval 7 and light by assorted interval 18; Blowing drum 14, clean grain interval 7 and light assorted interval 18 top outlet are communicated with; The assorted cylinder 19 of grain light assorted interval 18 below be provided with a light assorted outlet 2; Below clean grain interval 7, be provided with the clean grain stream plate 5 that an oval ring with clean grain interval 7 that gradient arranged matches, on the assorted cylinder 19 of grain below clean grain stream plate 5, be provided with a clean grain outlet 4.

Because the gently assorted winnowing machine of this grain is equipped with a Blowing drum 14 in adopting under the hopper 10 of the assorted cylinder 19 of grain, and rotate equal charging tray 12, at decelerator 9, motor 8 and impeller 6 fuse and adopt fixed support 13 uprightly to be installed in the centre in Blowing drum 14 intervals, rotate being used in combination of equal charging tray 12 and decelerator 9 or the like under adding elevating hopper 10 outlets, therefore the gently assorted winnowing machine of grain of the present invention adopts the gently assorted grain winnowing machine ratio of air draught type removal grain to have following advantage with selection by winnowing mode of the prior art: (1) paddy, wheat, brown rice equigranular material flows to the equal charging tray 12 of rotation from hopper 10 outlets, by the rotary centrifugal force of rotation homocline 12 dishes and the effect of the 6 rotation blowings of the impeller in the Blowing drum 14, clean grain in the grain and the light assorted clean grain interval 7 and light by assorted interval 18 that in the assorted cylinder 19 of grain, is separated to separately at an easy rate; Rotate the design that the assorted separation chamber of Rotating with Uniform, the grain decanter type of equal charging tray 12 separates and adopt air circulation bleed type wind-force to separate light impurity in paddy, wheat, the brown rice equigranular material or the like, make that the material impulsive force is little, sub-material increases material and moving air contact area evenly, greatly, separate good impurity removing effect, disposable separating treatment just can reach the storage standard of national regulation.(2) the gently assorted winnowing machine of this grain adopts the air circulating type blowing, and the blower fan electrical loss is low, reduces power of motor greatly, energy-efficient, complete machine structure is compacter, volume is little, in light weight, cost is low, uses light, simple to operate, be the optimal selection that plant equipment is stored up in present supporting grain processing.(3) this machine adopts cylinder oblique angle type discharger, and middle idle loop air intake can not produce dust pollution, very environmental protection outward to machine.(4) complete machine need not fixed installation, and mobile pulley is installed in the frame bottom, makes things convenient for machine to move at any time, installs an elevator at random additional, and is very easy to use, is suitable for very much farm zero grain and stores up.
